Abstract
Description
Technical Field
[0001] This utility model relates to a mechanism for preventing loosening of an assembled handle. Background Technology
[0002] In daily life, we often use cooking containers such as woks, frying pans, or soup pots. The handles of these pots are usually made of wood. The structure of the handle usually consists of a stud, a fireproof sleeve, and a handle. The handle is fixed to the stud by a fastening screw. Since the handle is directly fixed to the stud, all the force is borne by the stud. Therefore, after a period of use, the handle may become loose. Utility Model Content
[0003] This utility model provides a mechanism to prevent loosening of the assembled handle.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0005] A mechanism for preventing loosening of an assembled handle includes a welding stud, a connector, and a handle connected sequentially from the inside out. The welding stud has a welding point at its front end, which connects to a pot body, and a groove in the middle of its rear end. The connector has a first protrusion at its lower front end that mates with the groove. A support plate is located at the upper end of the first protrusion, and a fireproof ring is fitted onto the support plate, fixing it to the outside of the support plate and the welding stud. A second protrusion is located in the middle of the rear end of the connector. The upper end of the second protrusion is a ring with an internal thread. The handle has a guide hole radially arranged in the middle. The front end of the guide hole mates with the second protrusion. A locking screw guides the through hole and engages with the connector. The front end of the locking screw has an external thread that engages with the internal thread for fixation.
[0006] Preferably, a first screw hole is provided on both sides of the rear end of the welding point, and a first through hole is provided on the left and right sides of the connector body opposite to the first screw hole. The connector is fixed on the first screw hole by screws passing through the first through hole.
[0007] Preferably, the groove is located in the middle of the first screw holes on both sides.
[0008] Preferably, the lower end of the second protrusion is provided with an extension block.
[0009] Preferably, the rear end of the handle is provided with a hook.
[0010] Preferably, the hook is provided with a second through hole opposite to the guide through hole, and a locking screw passes through the second through hole and the guide through hole from the rear end of the hook to cooperate with the connector.
[0011] Preferably, the fireproof ring is made of aluminum or stainless steel.
[0012] Preferably, the handle is made of bakelite, steel, aluminum or wood.
[0013] Preferably, the guide through hole is a tapered shape that is narrow at the front and wide at the back.
[0014] Compared with the prior art, the anti-loosening assembled handle mechanism of this utility model welds the studs to the pot body and uses screws to fix the connecting parts to the studs. At the same time, fireproof rings are fitted on the front end of the connecting parts and the outside of the studs. A guide through hole is set in the radial direction of the handle, and a locking screw passes through the first through hole and the guide through hole from the rear end of the hook and connects to the connecting parts. The external thread of the locking screw cooperates with the internal thread of the rear end of the connecting parts to fix the handle to the connecting parts. The handle is detachably connected to the connecting parts, which is convenient for subsequent replacement and maintenance. Moreover, the handle is fixed to the pot body by the studs and the connecting parts, and the fireproof ring is set at the connection point to prevent the welding point from being loosened by high temperature.

[0021] The connector 3 has a first protrusion 32 on its lower front end that mates with the groove 13. A support plate 31 is located at the upper end of the first protrusion 32, and a fireproof ring 2 is fitted onto the support plate 31. The connector 3 has first through holes 33 on its left and right sides, corresponding to the first screw holes 12. The connector 3 is fixed to the first screw holes 12 by screws passing through the first through holes 33, thus fixing the connector 3 to the welding stud 1. The fireproof ring 2 is fixed to the support plate 31 and the outside of the welding stud 1. A second protrusion 34 is located at the middle of the rear end of the connector 3. The upper end of the second protrusion 34 is a ring with an internal thread 341. An extension block is located at the lower end of the second protrusion 34, which can distribute the force exerted by the second protrusion 34. The fireproof ring 2 is made of aluminum or stainless steel.
[0022] The handle 4 has a radially arranged guide through hole 41 that is tapered at the front and wide at the back. The front end of the guide through hole 41 mates with the second protrusion 34. The front end of the hook 6 is fitted onto the rear end of the handle 4. The hook 6 has a second through hole 61 opposite to the guide through hole 41. A locking screw 5 passes through the second through hole 61 and the guide through hole 41 from the rear end of the hook 6 and mates with the connector 3.
