Abstract

An unpowered stop mechanism includes a mounting seat, a driving member, and a stop assembly. The stop assembly is located on the mounting seat and oppositely positioned to the driving member. The stop assembly includes a guide member, a stop member, and a hinge arm. The stop member is received within a guide slot defined in the guide member. The hinge arm is pivotably coupled to the guide member. The hinge arm protrudes from the guide member and is oppositely positioned to the driving member. The driving member drives the hinge arm to drive the stop member to retract within the guide slot. Then the driving member is moved to be spaced from the hinge arm, the stop member is driven by a resilient member received within the guide slot to protrude out of the guide slot.

First claim

What is claimed is:

1. An unpowered stop mechanism comprising:
a mounting seat;
a driving member; and
a stop assembly;
wherein the stop assembly is located on the mounting seat;
wherein the stop assembly is spaced from the driving member;
wherein the stop assembly comprises a guide member, a stop member, and a hinge arm;
wherein the stop member is received within a guide slot defined in the guide member;
wherein the hinge arm is pivotably coupled to the guide member;
wherein the hinge arm protrudes from the guide member and is spaced from the driving member;
wherein when the driving member is moved to abut on the hinge arm, the driving member drives the hinge arm to drive the stop member to retract within the guide slot; and
wherein when the driving member is moved to be spaced from the hinge arm, the stop member is driven by a resilient member received within the guide slot to protrude out of the guide slot.

2. The unpowered stop mechanism of claim 1 , wherein the mounting seat comprises a mounting end; the stop assembly is located at an end of the mounting seat opposite to the mounting end; the stop assembly is oriented perpendicularly to the mounting seat to orient the stop member of the stop assembly on a lateral side of the mounting seat; the hinge arm comprises a protruding end protruding from the end of the mounting seat opposite to the mounting end; the protruding end is spaced from the driving member.

3. The unpowered stop mechanism of claim 1 , wherein the guide slot and the hinge arm are located on an outer surface of the guide member; an upper portion of the guide slot receives the stop member, and a lower portion of the guide slot receives the resilient member; the resilient member resists against the stop member; the hinge arm spans across the guide slot.

4. The unpowered stop mechanism of claim 3 , wherein a base plate is located at a bottom end of the guide slot to cause the stop member resisted against by the resilient member to protrude out of a top end of the guide slot.

5. The unpowered stop mechanism of claim 3 , wherein the guide slot is a dovetail slot; the stop member is a sliding block slidably received within the guide slot; the stop member comprises a protruding block located at a bottom end of the guide slot; the protruding block protrudes from a surface of the stop member and abuts on the hinge arm.

6. The unpowered stop mechanism of claim 5 , wherein the hinge arm comprises a hinge end pivotably coupled at an end of the guide slot receiving the stop member; the hinge arm further comprises a first edge and a second edge opposite to the first edge, the second edge of the hinge arm abuts on the protruding block; a limiting pin protruding from an outer surface of the guide member is located at the first edge of the hinge arm; the limiting pin is located at an end of the guide slot spaced from the hinge end; the limiting pin limits movement of the hinge arm.

7. The unpowered stop mechanism of claim 6 , wherein the hinge arm and the protruding block move relative to each other; when the hinge arm pushes the protruding block, the stop member retracts into the guide slot; when the protruding block pushes the hinge arm, the stop member extends out of the guide slot; extension of the stop member out of the guide slot is limited by the limiting pin.

8. The unpowered stop mechanism of claim 2 , wherein the driving member comprises a driving mechanism and a driving block spaced from the protruding end of the hinge arm; the driving block is driven by the driving mechanism to push the protruding end to cause the hinge arm to drive the stop member.

9. The unpowered stop mechanism of claim 8 , wherein the driving block comprises an inclined surface; the protruding end is a curved end; the inclined surface applied on the curved end allows the driving member to drive the hinge arm.

10. The unpowered stop mechanism of claim 1 , wherein the mounting seat comprises a transport frame; the mounting seat is located on a lateral side of the transport frame so that the stop mechanism on the mounting seat on the lateral side of the transport frame stops a workpiece carried on the transport frame; the driving member is outside of the transport frame and spaced from the stop assembly; when the transport frame is moved to be spaced from the driving member, the stop member is positioned to stop the workpiece carried on the transport frame; when the hinge arm of the stop assembly of the transport frame is moved to abut on the driving member, the stop member is not in position to stop the workpiece carried on the transport frame.
