Detailed Description

The present invention will be described in detail with reference to the following embodiments.

The device of the invention is shown in figures 1 to 3, and the whole mechanism of the device is arranged on a feeding rack 2 through a mounting rack 1. Striker 3 installs in the inside recess of mounting bracket 1, and the latch segment 4 welding is outside on the mounting bracket 1 right side, and latch 5 passes latch segment 4, striker 3 and mounting bracket 1 respectively from the right side, and 5 one end designs for square cross-section, the other end be circular cross-section and have excessive complex pinhole in circular cross-section middle part design of bolt. The rightmost end of the bolt 5 is provided with a handle 8 fixed by a pressing gasket 6 and a nut 7, a locking spring 9 is arranged between the handle 8 and the locking block 4, the bolt 5 is provided with a locking pin 10, and the locking pin 10 can lock the bolt 5 and the locking block 4.

A first-stage stepped hole 401 and a second-stage stepped hole 402 are formed in the locking block 4, symmetrical first long hole grooves 403 are formed in the first-stage stepped hole 401, symmetrical second long hole grooves 404 are formed in the same positions of the first-stage stepped hole 401 and the second-stage stepped hole 402, and the first long hole grooves 403 and the second long hole grooves 404 are vertically arranged in the circumferential direction.

When the handle is used, the square cross section end of the bolt 5 is arranged in the square hole of the handle 6, and the handle 8 is fixed by the compression gasket 6 and the nut 7. Locking spring 9 suit is on bolt 5, lean on tight handle 8 until one end, pack into fitting pin 10 with bolt 5, anticlockwise rotation handle 8 loosens handle 8 to vertical position, under locking spring 9's effect, bolt 5 takes fitting pin 10 to follow the first rectangular hole groove 403 and the rectangular hole groove 404 of second right motion of latch segment 4, until fitting pin 10 outcrop leans on at the bottom of the first rectangular hole groove 403 on latch segment 4 closely, so far bolt 5 realizes locking for the first time. When needing to change stock stop 3, hold handle 8 level and promote bolt 5 left, compression locking spring 9, the fitting pin 10 moves left along the first rectangular hole groove 403 and the rectangular hole groove 404 of second of latch segment 4, until fitting pin 10 exposes the head and holds mounting bracket 1 right side, clockwise turning handle 8 to the horizontal position, remove horizontal thrust left, bolt 5 moves right under locking spring 9's effect, bolt 5 drives fitting pin 10 and follows the slotted hole roll-off of latch segment 4 simultaneously, pull out bolt 5 with handle 8 this moment, remove original stock stop 3, so far, accomplish the unblock. When the material stopper 3 is installed next time, the material stopper can be locked again by the first locking operation. The locking and unlocking can be operated repeatedly, and the locking and the dismounting of the material stopper 3 are realized.

The bolt locking mechanism has the advantages of simple structure, small occupied space and light operation, ensures the safe and reliable locking of the bolt of the stock stop, and simplifies the complex work of unlocking the stock stop. The problem of tumbling and transferring when the material stopper works is solved, and the material stopper is more easily and conveniently replaced. The device can prevent the material stopper from tipping and moving horizontally during working. The locking spring is matched with the locking pin for use, the structure is simple, the occupied space is small, the operation is light, and the safe and reliable locking of the bolt of the material stopper is ensured.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the present invention.
