Abstract

A device for installing an elastic sealing ring on an electronic device includes a clamp module and a pressing module. The clamp module includes a sliding column defining two grooves, two linkage plates, and two pins secured on the bottom end of the linkage plates. The pressing module includes a bracket and a knockout plate. The linkage plates are rotatably installed on the bracket and the sliding column can slide relative to the bracket. The knockout plate can slide relative to the bracket, to install the sealing ring on an electronic device.

First claim

What is claimed is:

1 . An installation fixture configured to install a sealing ring on an electronic device comprising:
a clamp module comprising:
a sliding column defining two grooves;
two linkage plates; and
two pins secured on the bottom end of the linkage plates;
a pressing module comprising:
a bracket; and
a knockout plate;
wherein the linkage plates are rotatably installed on the bracket, the sliding column being slidable relative to the bracket to locate the two pins in a first position or in a second position; wherein when the two pins are in the first position, the top end of the linkage plate resists against the sliding column, the two pins are proximate one another and passed through the knockout plate; wherein when the two pins are in the second position, the sliding column is slid down and the top end of the linkage plates are received in the grooves, the two pins are further away from each other than when in the first position to elastically expand the sealing ring, the knockout plate being slid relative the bracket to install the sealing ring on the electronic device.

2 . The installation fixture of claim 1 , wherein the bracket defines two limiting holes, each linkage plate defines two pivot holes, a pivot shaft is inserted into the pivot holes and the limiting holes to rotatably install the linkage plate on the bracket.

3 . The installation fixture of claim 2 , wherein the each linkage plate defines a blind hole below the pivot hole, and a second resilient member is elastically constricted and two opposite ends of the second resilient member are received in the two blind holes.

4 . The installation fixture of claim 3 , wherein sliding column comprises four sidewalls, a protrusion extending from the top end of each linkage, when the two pins are in the first position, the second resilient member responds to resist the protrusion against the sidewall.

5 . The installation fixture of claim 1 , wherein each side of the bracket comprises a securing pole, each securing pole defines a plurality of securing holes, the installation fixture further comprises a shell, a plurality of fasteners pass through the shell to insert into the securing holes to secure the bracket in the shell.

6 . The installation fixture of claim 5 , wherein the bracket defines a receiving groove between the two securing poles, the pressing module comprises a positioning pole received in the receiving groove, the sliding column are set on the positioning pole.

7 . The installation fixture of claim 6 , wherein the pressing module further comprises a third resilient member, two opposite ends of the third resilient member are respectively relied on the receiving groove and the sliding column, the third resilient member can respond to slide up the sliding column.

8 . The installation fixture of claim 5 , wherein the shell comprises a front plate, the inside of the front plate is equipped with a latch member, the clamp module comprises a clamp switch, the latch member can be rotated to secure on the clamp switch.

9 . The installation fixture of claim 8 , wherein the latch member comprises a stopper block, the pressing module comprises a pressure pole, the pressure pole can be relied on the stopper block.

10 . The installation fixture of claim 1 , wherein the pressing module further comprises a pressing switch and a connecting plate connected with the pressing switch, the pressing switch is capable of pushing the connecting plate to push the knockout plate to install the sealing ring on the electronic device.

11 . A sealing ring installation mechanism comprising:
a sealing ring; a clamp module comprising:
a sliding column defining two grooves;
two linkage plates; and
two pins secured on the bottom end of the linkage plates;
a pressing module comprising:
a bracket; and
a knockout plate;
wherein the linkage plates are rotatably installed on the bracket, the sliding column being slidable relative to the bracket to locate the two pins in a first position or in a second position; wherein when the two pins are in the first position, the top end of the linkage plate resists against the sliding column, the two pins are proximate one another and passed through the knockout plate; wherein when the two pins are in the second position, the sliding column is slid down and the top end of the linkage plates are received in the grooves, the two pins are further away from each other than when in the first position to elastically expand the sealing ring, the knockout plate being slid relative the bracket to install the sealing ring on an electronic device.

12 . The sealing ring installation mechanism of claim 11 , wherein the bracket defines two limiting holes, each linkage plate defines two pivot holes, a pivot shaft is inserted into the pivot holes and the limiting holes to rotatably install the linkage plate on the bracket.

13 . The sealing ring installation mechanism of claim 12 , wherein the each linkage plate defines a blind hole below the pivot hole, and a second resilient member is elastically constricted and two opposite ends of the second resilient member is received in the two blind holes.

14 . The sealing ring installation mechanism of claim 13 , wherein sliding column comprises four sidewalls, a protrusion extending from the top end of each linkage plate, when the two pins are in the first position, the second resilient member responds to resist the protrusion against the sidewall.

15 . The sealing ring installation mechanism of claim 11 , wherein each side of the bracket comprises a securing pole, each securing pole defines a plurality of securing holes, the installation fixture further comprises a shell, a plurality of fasteners pass through the shell to insert into the securing holes to secure the bracket in the shell.

16 . The sealing ring installation mechanism of claim 15 , wherein the bracket defines a receiving groove between the two securing poles, the pressing module comprises a positioning pole received in the receiving groove, the sliding column are set on the positioning pole.

17 . The sealing ring installation mechanism of claim 16 , wherein the pressing module further comprises a third resilient member, two opposite ends of the third resilient member are respectively relied on the receiving groove and the sliding column, the third resilient member can respond to slide up the sliding column.

18 . The sealing ring installation mechanism of claim 15 , wherein the shell comprises a front plate, the inside of the front plate is equipped with a latch member, the clamp module comprises a clamp switch, the latch member can be rotated to latch on the clamp switch.

19 . The sealing ring installation mechanism of claim 18 , wherein the latch member comprises a stopper block, the pressing module comprises a pressure pole, the pressure pole can be relied on the stopper block.

20 . The sealing ring installation mechanism of claim 1 , wherein the pressing module further comprises a pressing switch and a connecting plate connected with the pressing switch, the pressing switch is capable of pushing the connecting plate to push the knockout plate to install the sealing ring on the electronic device.
