Description

Technical Field

[0001] This utility model belongs to the field of fastening tool technology, specifically relating to a sliding sleeve mechanism for a nail gun and a nail gun. Background Technology

[0002] Common fastening tools, such as nail guns, are fastening tools that use nails as fasteners and nozzles as the output end of the fastener. They are mostly used in construction and home renovation. A nail gun uses a drive motor and a corresponding transmission structure to push a piston. The piston compresses a force spring or compressed gas to store energy. When firing a nail, the force spring or air pressure drives the piston, which in turn moves a firing pin mounted on the piston to strike and eject the nail, thus achieving nailing.

[0003] Nail guns use different nailing structures for different application scenarios. For example, insulation nails used for installing building insulation panels need to be mounted on the nail gun nozzle via a sliding sleeve due to their special properties. The sliding sleeve usually corresponds to only one size and model of nail gun. When multiple different sizes and models of insulation nails need to be used in the same scenario, the nail gun sliding sleeve needs to be replaced.

[0004] Existing nail guns with replaceable sleeves typically have the sleeves fixed to the nozzle using screws or similar methods. Replacing the sleeve requires a rather cumbersome disassembly process, which is very inconvenient. Summary of the Invention

[0005] To solve the above problems, this utility model provides a nail gun with a sliding sleeve mechanism that can be quickly disassembled, replaced and installed, as well as a nail gun.

[0010] The sliding sleeve mechanism for a nail gun proposed in this utility model also has the following feature: the portion of the mounting sleeve that extends into the mounting hole has a threaded section, through which the mounting sleeve is connected to the mounting hole.

[0011] The sliding sleeve mechanism for a nail gun proposed in this utility model also has the following features: the spring is installed between the outer periphery of the push-pull rod and the inner wall of the through hole, and the end of the push-pull rod away from the push-pull cap is provided with a first protrusion for abutting one end of the spring, and the end of the through hole near the push-pull cap is provided with a second protrusion for abutting the other end of the spring.

[0013] The sliding sleeve mechanism for nail guns proposed in this utility model also has the following feature: the push-pull cap is integrally or separately disposed from the push-pull rod. When the push-pull cap is separately disposed from the push-pull rod, the push-pull cap is fixed to the push-pull rod by a pin or by welding or screwing.

[0014] The sliding sleeve mechanism for a nail gun proposed in this utility model also has the following feature: the anti-reverse groove is a long groove, which is distributed along the axial direction of the sliding sleeve on the side wall of the sliding sleeve, and the length of the long groove along the axial direction is greater than the length of the inner end of the moving member along the axial direction.

[0015] The sliding sleeve mechanism for a nail gun proposed in this utility model also has the following feature: a protective bracket is slidably installed on the mounting part on the side of the mounting assembly near the gun body.

[0018] Functions and effects of utility models

[0019] According to the present invention, a sliding sleeve mechanism for a nail gun and a nail gun are provided.

The sliding sleeve can then be removed for disassembly or moved into the sliding sleeve for installation. Disassembly and replacement are very convenient and quick. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes in detail the sliding sleeve mechanism for the nail gun and the nail gun of this utility model with reference to the embodiments and accompanying drawings.

[0028] <Example 1>

[0029] This embodiment proposes a nail gun, particularly a nail gun with a sliding sleeve, including a gun body (not shown) and a sliding sleeve mechanism 20 (i.e., a sliding sleeve mechanism 20 for a nail gun). The front side of the gun body has a nozzle 10, and the sliding sleeve mechanism 20 is mounted on the nozzle 10 for mounting nails. Figure 1 and Figure 2 As shown, the sliding mechanism 20 includes a sliding sleeve 21, a mounting part 22, and a mounting assembly 23. The sliding sleeve 21 is elongated and has a nail channel 211 inside for mounting nails. One end of the sliding sleeve can extend into the mounting part 22 to form an internal section, and the other end extends out of the mounting part 22 to form an external section. One end of the mounting part 22 is integrally or separately mounted on the nozzle 10 of the gun body, and the other end is used to mount the sliding sleeve 21. The sliding sleeve 21 is detachably mounted on the mounting part 22 via the mounting assembly 23.

[0030] Specifically, such as Figure 2 As shown, the mounting part 22 is separately mounted on the nozzle 10. The mounting part 22 has a mounting channel 221 for the inner section of the sliding sleeve 21 to extend into. The mounting assembly 23 has a moving part 231, a resetting part 232, and a mounting sleeve 233. The side wall of the mounting part 22 protrudes outward to form a mounting boss. A mounting hole 222 communicating with the mounting channel 221 is formed at the mounting boss along the radial direction of the mounting channel 221. The mounting hole 222 penetrates the side wall of the mounting part 22. The moving part 231 is movably mounted on the mounting part 22, with its outer end exposed outside the mounting part 22 and its inner end penetrating the side wall of the mounting part 22 and extending into the mounting channel 221. The resetting part 232 is a spring that acts on the moving part 231 to help the moving part 231 to reset. The inner section of the sliding sleeve 21 that extends into the mounting channel 221 has a retaining groove 212 for the inner end of the moving part 231 to extend into.

[0031] like Figure 2In the shown state, the sliding sleeve 21 is now installed with the mounting part 22. A spring is sleeved around the outer periphery of the portion of the moving part 231 that extends into the mounting hole 222. Under the spring's force, the inner end of the moving part 231 extends into the anti-reverse groove 212. At this time, due to the restriction of the groove wall of the anti-reverse groove 212, the movement stroke of the sliding sleeve 21 relative to the mounting channel 221 is limited. Simultaneously, it prevents the sliding sleeve 21 from falling out when the moving part 231 contacts the groove wall of the anti-reverse groove 212, ensuring the stability of the sliding sleeve 21's installation. When it is necessary to remove the sliding sleeve 21 for replacement, simply move the moving part 231 outwards, causing its inner end to leave the anti-reverse groove 212, releasing the restriction between the moving part 231 and the anti-reverse groove 212, and then the sliding sleeve 21 can be removed for disassembly. Similarly, during installation, simply move the moving part 231 outward, insert the inner section of the sliding sleeve 21 into the installation channel 221, and then remove the outward force on the moving part 231. Under the elastic action of the spring, push the moving part 231 inward so that its inner end is inserted into the anti-reverse groove 212 to complete the installation, which is very convenient.

[0032] In this embodiment, the user can move the movable component 231 outward by grasping the outer end of the movable component 231 exposed on the mounting portion 22 and pulling it outward. Further, as... Figure 2 As shown, the movable component 231 includes a push-pull cap 2311 and a push-pull rod 2312. The push-pull cap 2311 is located on the outside of the mounting part 22 for gripping. One end of the push-pull rod 2312 is connected to the push-pull cap 2311, and the other end passes through the side wall of the mounting part 22 and can extend into the mounting channel 221. A spring is sleeved on the outer periphery of the push-pull rod 2312. The push-pull cap 2311 and the push-pull rod 2312 can be integrally set or separately set. When separately set, the push-pull cap 2311 can be fixed to the push-pull rod 2312 by a pin 2313 or by welding.

[0033] like Figure 2 As shown, in this embodiment, the mounting sleeve 233 is a threaded sleeve. The portion of the mounting sleeve 233 that extends into the mounting hole 222 has a threaded section, through which the mounting sleeve 233 is threadedly connected to the mounting hole 222. A through hole 2331 is provided in the middle of the mounting sleeve 233 for the push-pull rod 2312 to pass through. The spring (i.e., the reset member 232) is installed between the outer periphery of the push-pull rod 2312 and the inner wall of the through hole 2331. The end of the push-pull rod 2312 away from the push-pull cap 2311 has a first protrusion 23121 for abutting one end of the spring, and the end of the through hole 2331 near the push-pull cap 2311 has a second protrusion 23311 for abutting the other end of the spring. The two ends of the spring are respectively limited so that the spring can be confined within the through hole 2331.

[0034] like Figure 2 and Figure 3As shown, the anti-reverse groove 212 is a long groove, which is distributed along the axial direction of the sliding sleeve 21 on the side wall of the sliding sleeve 21. The axial length of the long groove is greater than the axial length of the inner end of the moving part 231, so that the sliding sleeve 21 can still move within a certain range after installation. A protective bracket 31 is also slidably installed on the mounting part 22 on the side of the mounting assembly 23 near the nozzle 10. The end of the protective bracket 31 facing the mounting assembly 23 can extend into the mounting channel 221 and abut against the inner end of the sliding sleeve 21. When the sliding sleeve 21 moves, the sliding sleeve 21 can push the protective bracket 31 to move.

[0035] <Example 2>

[0036] This embodiment, based on embodiment 1 above, also includes a protection component 30, such as... Figure 5 As shown, the protective component 30 has a protective bracket 31, an elastic element 32, and a sensing element 33. The mounting part 22 is provided with a groove 223 on the side near the nozzle 10. The protective bracket 31 is slidably mounted on the groove 223. The end of the groove 223 away from the nozzle 11 is connected to the mounting channel 221, so that the end of the protective bracket 31 away from the nozzle 10 can extend into the mounting channel 221 and abut against the sliding sleeve 21 to form an abutment section 310. The elastic element 32 is disposed between the nozzle 10 and the protective bracket 31. The sensing element 33 is installed on the end of the protective bracket 31 near the nozzle 10. The nozzle 10 is provided with a sensor that senses the sensing element 33.

[0037] The sensing element 33 can be a magnetic induction magnet, and the sensor is preferably a Hall element used to sense the position of the magnetic induction magnet. When the sliding sleeve 21 moves inward and pushes the protective bracket 31 inward, the sensing element 33 will move along with the protective bracket 31. When the sensor detects that the sensing element 33 has moved to the set position, it sends a signal to the controller inside the machine body. At this time, the power supply of the control circuit is turned on, and the user can press the nail gun switch to allow the nail to be fired. The setting of the protective component 30 can prevent the nail gun from being fired accidentally, thus improving safety performance. The elastic element 32 is a spring. A spring seat 311 is formed at the end of the protective bracket 31 away from the nozzle 11. An installation port is formed on the side of the nozzle 11 facing the protective bracket 31. One end of the elastic element 32 extends into the installation port, and the other end rests on the spring seat 311, which facilitates the reset of the protective bracket 31.

[0038] <Example 3>

[0039] This embodiment is based on the above embodiments 1 and 2, such as Figure 6As shown, a guide slope 23122 is provided on the part of the push-pull rod 2312 that extends into the mounting channel 221 and / or on the end face of the sliding sleeve 21 that extends into the mounting channel 221. When installing the sliding sleeve, the inner end face of the sliding sleeve can guide the push-pull rod 2312 to move outward through the guide slope 23122, eliminating the need for manual lifting of the push-pull rod 2312, which is more convenient.

[0040] <Example 4>

[0041] The difference between this embodiment and the above embodiments 1-3 is that the mounting part 22 and the mounting sleeve 233 are integrally set, which can save the assembly of the mounting sleeve 233. However, it is necessary to open an avoidance hole on the side wall of the mounting part 22 below the mounting hole 222. The reset part 232 and the push-pull rod 2312 enter the interior of the mounting sleeve 233 in this embodiment through the avoidance hole. Then, the push-pull rod 2312 passes through the mounting hole 222 and is fixedly connected to the push-pull cap 2311 to realize the installation.

[0042] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the above embodiments.
