Abstract

A braking mechanism includes a rack, a receiving member, a braking member, a base seat, a resetting member and an elastic member. Two ends of the resetting member abut the base seat and the receiving member, and the elastic member is positioned between the base seat and the braking member. The elastic member and the resetting member are positioned at opposite sides of the braking member. The base seat includes a first guiding portion, the braking member includes a second guiding portion and an engaging part. The second guiding portion is capable of moving along the first guiding portion under an elastic restorative force of the resetting member and the elastic member, such that the engaging part is engaged with the rack.

First claim

a rack; a receiving member mounted on the rack; a braking member movably mounted on the receiving member; a base seat slidably mounted on the receiving member; a resetting member, two ends of the resetting member abutting the base seat and the receiving member; and an elastic member positioned between the base seat and the braking member; wherein the elastic member and the resetting member are positioned at opposite sides of the braking member; wherein the base seat comprises a first guiding portion, the braking member comprises a second guiding portion and an engaging part mounted on the first guiding portion, and the second guiding portion is slidably engaged with the first guiding portion; and wherein the second guiding portion is capable of moving along the first guiding portion under an elastic restorative force imposed by the resetting member and the elastic member, such that the engaging part is engaged with the rack.

2 . The braking mechanism as claimed in claim 1 , wherein the mechanism further comprises a resisting member, the resisting member is slidably mounted on the base seat and positioned between the elastic member and the braking member, and two ends of the elastic member abut the resisting member and the base seat.

3 . The braking mechanism as claimed in claim 2 ,
wherein the base seat comprises an extending portion protruded out of one end portion of the base plate away from the side plate, and the base seat comprises a sliding portion communicated with the first guiding portion; and wherein the resisting member is mounted in the sliding portion in a sliding way, and the elastic member is received in the extending portion.

4 . The braking mechanism as claimed in claim 3 , wherein the braking mechanism further comprises a driving member mounted at one side of the receiving member and adjacent to the elastic member, and the extending portion is capable of protruding out of the receiving member to abut the driving member.

5 . The braking mechanism as claimed in claim 2 , wherein the resisting member comprises a resisting portion, the resisting portion is protruded from one end of the resisting member toward the braking member and abuts the second guiding portion.

6 . The braking mechanism as claimed in claim 1 ,
wherein the receiving member comprises a base and an upper casing covered on the base, the upper casing define a receiving portion, and the base plate is slidably received in the receiving portion; wherein one end of the resetting member abuts the upper casing, and the base is fixed on the rack; and wherein the base defines a sliding groove through thereof, the engaging part passes through the sliding groove in a sliding way, and the engaging part is positioned spaced from the rack.

7 . The braking mechanism as claimed in claim 1 , wherein the base comprises a stopper portion, and the stopper portion is positioned between the resetting member and the braking member to restrict the movement of the braking member.

8 . The braking mechanism as claimed in claim 1 ,
wherein the number of the first guiding portion and the braking member are two, and a distance between the two first guiding portions is decreased along a direction away from the elastic member; and wherein each second guiding portion of the braking member is received in one of the first guiding portions.

9 . The braking mechanism as claimed in claim 1 ,
wherein the resetting member comprises a stiffener and a resetting part, one end of the stiffener is fixed at the base plate, and the resetting part is longer than the stiffener; and wherein the resetting part is sleeved on the stiffener, and two ends of the resetting part abut the base plate and the receiving member.

10 . A processing device comprising:
a fixing base; a sliding module mounted on the fixing base; a processing module mounted on the fixing base and being capable of moving with the sliding module; and a braking mechanism mounted in the receiving base, the braking mechanism comprising:
a rack mounted on the sliding module;
a receiving member mounted on the rack;
a braking member movably mounted on the receiving member;
a base seat mounted on the receiving member or the braking member;
a resetting member, two ends of the resetting member abutting the base seat and the receiving member; and
an elastic member positioned between the base seat and the braking member;
