Description

Pressure adjustment structure of nailing gun

technical field

The utility model relates to a hand-held U-shaped nail tool, in particular to a pressure adjustment structure of a nailing gun with less components and lower cost.

Background technique

The form of the binding tool is different according to the thickness, thickness and material of the object to be bound. Please refer to Fig. 4 and Fig. 5. Fig. 4 is a partially exploded three-dimensional schematic diagram of an existing nail gun, and Fig. 5 is an existing A partial top view sectional view of the nailing gun. FIG. 6 is a partial combined structure sectional view of the existing nailing gun. The nail gun is assembled with a needle slot (not shown) at the bottom of the body 50, a front cover 51 is assembled at the front end, and a handle 52 is pivotally arranged at the end of the body 50 adjacent to the front cover 51, and the front end of the handle 52 is Pressed by a striker spring 53 at the top, the front cover 51 has two sides and a front side, the top of the front side is higher than the two sides, and a recess 510 is provided on the top of the two opposite sides. A nut 54 with a screw hole in the center is placed in the recess 510, and part of the peripheral edge of the nut 54 is cut into a plane to be attached to the front side of the front cover 51 so that the nut 54 cannot rotate. The top of the nut 54 is provided with an upper cover 55 covering the upper half of the nut 54 and the front cover 51. The upper cover 55 is inserted in the slot 511 at the front end of the front cover 51 with its front end, and the two sides Then, a bolt 512 is passed through and fixed on the front cover 51, and then a bolt 56 is screwed into the nut 54 from the outside, and, as shown in Figure 6, the end of the bolt 56 is passed through the striker spring 53, by The tightness of the striker spring 53 can be changed by the length of the adjusting bolt 56, and then the pressure on the handle 52 can be changed. When not in use, the free end of the handle 52 is tilted upwards. Press the handle 52 so that the striker located in the front cover 51 pushes out the needle body.

Detailed ways

Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the pressure adjustment structure of the nailing gun proposed according to the present invention will be described in detail as follows.

Please refer to FIG. 1 , which is a partially exploded three-dimensional schematic diagram of the pressure adjustment structure of the nailing gun of the present invention. The nailing gun used in the utility model is roughly the same as the existing product, that is, the front end of the body 10 is covered and closed with a front cover 20 with three perimeters, and the tops of the two sides of the front cover 20 are lower than the front side. On the front side, a slot 21 with a position higher than the top of the side is provided, and a handle 23 is pivotally arranged on the side of the body 10 adjacent to the front cover 20, and the front end top of the handle 23 is placed on the front cover 20. The striker spring 24 within the range is pressed, and a pressure adjustment structure 30 is provided on the top of the front cover 20 to adjust the force of the striker spring 24 pressing on the handle 23 . In order to achieve the purpose of reducing components and reducing costs, the utility model specially improves the design of the pressure adjustment structure 30 .

Please refer to Fig. 1 and Fig. 2, the pressure adjustment structure 30 of the present invention is composed of an upper cover 31 and a bolt 32, wherein the upper cover 31 is formed by punching a metal plate with two sides The structure of the plate 310 and a top plate 311, the two side plates 310 are punched with a coaxial through-hole 312 at the same time, and the middle of the top plate 311 is punched with a center with a perforation and extends in the same direction as the side plate 310 The protruding portion 313 (the protruding portion 313 can also extend oppositely to the side plate 310 ) is formed with a screw hole in the perforation of the protruding portion 313 , and a flange 314 is protruded from the front edge of the top plate 311 .

When the utility model is assembled, the upper cover 31 is covered on the top of the front cover 20, and the flange 314 is inserted into the slot 21 of the front cover 20, and then a latch 33 is placed in the perforation on the side plate 310. 312 and the two sides of the front cover 20 are fixed, and then the bolt 32 is screwed in the screw hole of the upper cover 31, and the end of the bolt 32 is placed on the end face of the striker spring 24, and the adjustment bolt 32 is screwed. The depth can change the tightness of the striker spring 24 and the pressure applied to the handle 23.

It can be seen from the above that the pressure adjustment structure of the present invention only has the upper cover 31 and the bolts 32, and the forming method of the upper cover 31 is as shown in Figure 3, directly punching out the two side plates of the upper cover 31 with a metal plate 310, top plate 311, flange 314, perforation 312, protrusion 313, and the perforation in protrusion 313 can be processed into screw holes in the perforation of protrusion 313. Therefore, the design of the present utility model can greatly shorten the processing process And time, not only do not need to manufacture the screw cap and the upper cover separately like existing products, but also the assembly is more convenient, fast and can reduce the cost, and indeed has the effect of promotion.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those skilled in the art, without departing from the scope of the technical solution of the present utility model, can use the structure and technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but all without departing from the utility model The content of the new technical solution, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the utility model.
