Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and specifically to a driving structure for a nail gun. Background Technology

[0002] Most existing nail guns use a motor to drive an eccentric wheel, which in turn pushes a slider, which is then fired by a spring. For example, the nail gun shown in publication number CN113977528A has an eccentric wheel mounted above a reducer to drive the slider. However, the stroke of existing equipment is mostly large, and the eccentric force generated when the eccentric wheel rotates is also transmitted to the reducer or motor, causing damage. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed driving structure for a nail gun that addresses the defects and shortcomings of the existing technology, thereby solving the aforementioned deficiencies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a rotating shaft for connecting a motor or reducer to a nail gun, a drive wheel connected to the top of the rotating shaft, and a slider that works in cooperation with the drive wheel above the drive wheel. The slider is used to be installed on a slide bar inside the nail gun to perform a firing action.

[0005] Preferably, the drive wheel is long and narrow, with one end being arc-shaped and a connecting hole provided inside the end. The shaft is connected to the connecting hole, and drive rod one and drive rod two are respectively provided on the upper sides of the other end.

[0006] Preferably, on one side of the bottom of the slider, there are two push blocks, one protruding downwards and the other pushing block, respectively. When the inclined drive wheel in front of the push block 2 rotates, the drive rod 1 pushes the push block 2 first, and then the drive rod 2 pushes the push block 1, and then it is released and fired.

[0007] Preferably, the slider has multiple sliding holes and is slidably mounted on the slide rod through the sliding holes.

[0008] Preferably, the rotating shaft is provided with bearing one and bearing two, and is installed through bearing one and bearing two.

[0009] The beneficial effects of this utility model after adopting the above structure are: This application has a simple structure, utilizing dual drive rods and a push block. The two sets of structures take turns contacting and acting to form a complete push, which in turn fires the nail gun. The structure is stable and efficient, with a short stroke and a long battery life.

[0010] In this application, the rotating shaft is assisted by dual bearings to reduce the damage to the motor or reducer caused by the drive wheel bias force. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] See Figures 1-3 As shown, it includes a rotating shaft 1 for connecting a motor or reducer to a nail gun. A drive wheel 4 is connected to the top of the rotating shaft 1. A slider 8 that works with the drive wheel 4 is provided above the drive wheel 4. The slider 8 is used to be installed on a slide bar inside the nail gun to perform a firing action. The drive wheel 4 is long and narrow, with one end being arc-shaped. A connecting hole 5 is opened in the end, and the shaft 1 is connected to the connecting hole 5. The upper sides of the other end are respectively provided with drive rod 1 6 and drive rod 2 7. On one side of the bottom of the slider 8, there are push blocks 1 10 and push blocks 2 11 protruding downwards and to the front and back, respectively. The front side of push block 2 11 is inclined. When the drive wheel 4 rotates, drive rod 1 6 pushes push block 2 11 first, and then drive rod 2 7 pushes push block 1 10, and then releases and fires. The slider 8 has multiple sliding holes 9, which are slidably installed on the slide rod. The shaft 1 is provided with bearing 1 2 and bearing 2 3, which are installed through bearing 1 2 and bearing 2 3.

[0015] During the action, such as Figure 4 As shown, after the last firing, drive lever 6, drive lever 7, push block 10, and push block 21 are not in contact, and drive wheel 4 rotates clockwise until... Figure 5-6 In the state shown, drive rod 6 enters between push block 10 and push block 21, and comes into contact with the surface of push block 21. As it rotates, it causes push block 21 and slider 8 to slide to the left until... Figure 7 As shown, drive lever 6 approaches the edge of push block 11 and slides outward, while drive lever 7 approaches push block 10 until... Figure 8-9 In the state shown, drive lever 6 moves away from push block 11, drive lever 7 abuts against push block 10, and continues to push slider 8 to slide until... Figure 10 As shown, after the second drive rod 7 leaves the first push block 10, it loses its force on the slider 8. The slider 8 can then be ejected to the right by the spring inside the nail gun to fire. The spring structure and position are common existing technologies and are omitted in this application. From the moment the drive rod 16 contacts the push block 21 to the moment of firing, the drive wheel 4 rotates less than 180° to complete a single firing. The slider 8 has a long stroke, but the drive wheel 4 has a short rotation stroke, resulting in a strong nail gun endurance. The nail gun motor is a brushless motor that stops rotating when released, so the slider 8 can stop at any position during the stroke, which is convenient for maintenance.

[0016] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0017] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
