Description

Hot air gun front cover rotation clamping structure

technical field

The utility model relates to a rotating clamping structure of a front cover of a hot air gun.

Background technique

The heat gun is mainly a tool for welding and picking components by using the hot air blown from the gun core of the heating resistance wire. For the convenience of manufacture, the shell of the heat gun is usually divided into two parts and manufactured separately, and then assembled with screws, and the gun head part of the shell needs to be fixed with the front cover, but the connection between the front cover of the existing heat gun and the gun head part of the shell Usually threaded connection is used, which will lead to unreliable fixation due to wear and tear in the process of loading and unloading, short service life, and often need to be replaced, which increases the production cost.

Contents of the invention

The technical problem to be solved by the utility model is to provide a rotating clamping structure for the front cover of the heat gun, which has a simple structure, reliable clamping, is not easy to wear, and can reduce production costs.

In order to solve the above-mentioned existing technical problems, the utility model adopts the following scheme: the rotating clamping structure of the front cover of the heat gun, including the main body of the front cover and the clamping part corresponding to the main body of the front cover, and the main body of the front cover is provided with at least one For a symmetrical clamping block, the clamping portion is provided with a clamping groove corresponding to the clamping block.

Preferably, the engaging portion is provided with a push slot corresponding to the block, and the push slot is correspondingly connected with the draw slot. The connection between the main body of the front cover and the clamping portion is facilitated.

Preferably, a locking elastic piece corresponding to the locking block is provided in the locking groove, and the locking elastic piece is connected with the pushing groove. The connection between the main body of the front cover and the clamping part is made more reliable by using the clamping elastic piece.

A pair of symmetrically arranged blocks are used. The manufacture is convenient and the cost is low.

Beneficial effect:

The utility model adopts the above-mentioned technical scheme to provide a rotary locking structure for the front cover of the hot air gun, which has a simple structure, reliable locking, and is not easy to wear and tear, thereby reducing the production cost.

Fig. 3 is a sectional view of plane A-A in Fig. 2 .

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the front cover rotation clamping structure of the heat gun includes a front cover main body 1 and a snap joint part 2 corresponding to the front cover main body 1, and the front cover main body 1 is provided with at least one For the symmetrical clamping block 3 , the clamping portion 2 is provided with a clamping slot 4 corresponding to the clamping block 3 . The clamping portion 2 is provided with a push slot 5 corresponding to the clamp block 3 , and the push slot 5 is correspondingly connected with the clamp slot 4 . The clamping slot 4 is provided with a clamping elastic piece 6 corresponding to the clamping block 3 , and the clamping elastic piece 6 is connected with the pushing groove 5 . The clamping blocks 3 adopt a pair arranged symmetrically.

In actual use, the front cover main body 1 is sleeved on the clamping part 2, and the clamping block 3 is pushed along the advancing groove 5 to the tail of the advancing groove 5, and then the front cover main body 1 is rotated so that the clamping block 3 is inserted into the engaging slot 4 , under the action of the clamping elastic piece 6, the clamping block 3 is fixed in the clamping groove 4, the structure is simple, the clamping is firm, it is not easy to wear, and the production cost is reduced. In order to further reduce the production cost, a part of the middle part of the clamping block 3 can be removed, and the front end and the tail end can be kept, and the effect is the same.
