Description

Technical Field

[0001] This utility model relates to a quick-lock structure for a seat foam mold frame. Background Technology

[0002] When using a seat foam mold frame, it needs to be used back and forth between the production line and the transport vehicle (transfer rack). That is, it is placed on the production line during production and placed on the transfer rack when not in production. Since the seat foam mold frame needs to be repeatedly loaded and unloaded, a convenient quick-release device is required. Therefore, this application provides a quick-lock structure for a seat foam mold frame. Summary of the Invention

[0003] This utility model provides a quick-lock structure for a seat foam mold frame to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A quick-lock structure for a seat foam mold frame includes a lock seat, a lock pin, a spring, and a wrench. The lock seat has an arc-shaped lock groove and a mounting hole. The lock pin is elastically supported in the mounting hole by the spring, and the bottom end of the lock pin extends into the arc-shaped lock groove, while the top end is placed on the outside of the lock seat and fixedly connected to the wrench.

[0006] Furthermore, the locking pin extends obliquely into the arc-shaped locking groove.

[0007] Furthermore, the locking pin has a stepped surface, with the bottom end of the spring abutting against the stepped surface and the top end abutting against the wrench.

[0008] This utility model has the following beneficial effects:

[0009] This invention only requires one locking shaft to be installed on the production line and the transfer rack respectively. When in use, the quick-lock structure is locked on the locking shaft. When used on the production line, the lower mold frame of the seat foam mold frame can also be opened along the locking shaft, that is, the lock seat rotates along the locking shaft. No additional extra structure is required. It combines quick-locking and opening into one, making the structure more compact and the performance better. Attached Figure Description

[0010] Figure 1 This is a structural diagram of the present utility model.

[0011] Figure 2 This is a structural diagram of the seat foam mold frame on the transfer rack.

[0012] Figure 3 This is a schematic diagram of the assembly of the seat foam mold frame on the circular foam production line. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figures 1 to 3 This utility model discloses a quick-lock structure for a seat foam mold frame, comprising a lock seat 311, a lock pin 312, a spring, and a wrench 313. The lock seat 311 has an arc-shaped lock groove 314 and a mounting hole, which are connected. The lock pin 312 is elastically supported in the mounting hole by the spring. The lock pin 312 is arranged at an angle and has a stepped surface. The bottom end of the spring abuts against the stepped surface, and the top end abuts against the wrench 313. The bottom end of the lock pin 312 extends into the arc-shaped lock groove 314, and the top end is positioned outside the lock seat 311 and fixedly connected to the wrench 313.

[0015] Both the transfer base 12 and the annular foaming production line are equipped with locking shafts. The locking shafts are placed in the arc-shaped locking groove 314, and the locking pin 312 is placed below the locking shaft, limiting the locking seat 311 on the locking shaft. When removing, pull the wrench 313 outward and rotate it 180°, so that the locking pin 312 disengages from the arc-shaped locking groove 314. Under the action of the spring, the wrench 313 abuts against the outer wall of the locking seat 311.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
