Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and in particular to a chuck assembly, a nail gun, and a nail gun kit. Background Technology

[0002] A nail gun is a fastening tool, primarily used in construction. It works by using a motor and transmission mechanism to drive a piston, which in turn compresses a spring or compressed gas to store energy. During nailing, the spring or gas pressure drives the piston, which in turn strikes the nail with a striker mounted on the piston, propelling the nail from the nozzle. Another type of nail gun, to prevent accidental nailing, incorporates a nozzle slide. This slide abuts against the substrate, disengaging the safety mechanism before the trigger can be pulled. In this design, the nozzle slide is positioned at the front of the nozzle. To facilitate targeted nailing of different pipe clamps, a functional head is installed at the front of the nozzle. If the nail gun has a nozzle slide, this functional head assists in the nailing process.

[0003] Currently, there are many types of pipe clamps on the market (saddle clamps, clamp clips, conduit strip clamps, ceiling bracket clamps, gas clamps, etc.), and nail guns require a wide variety of functional heads. Consequently, technicians who need to assemble pipe clamps need to carry multiple different functional heads to adapt to different pipe clamps before starting the assembly work. During the pipe clamp assembly process, it is necessary to constantly change functional heads to adapt to different pipe clamps, which will lead to the following problems:

[0004] 1. Inconvenient to carry: Technicians need to carry multiple functional heads, which increases their workload and makes carrying them more difficult.

[0005] 2. Frequent replacement: During the assembly process, technicians need to frequently replace the functional heads according to different pipe clamp types, which reduces work efficiency. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art, the present invention provides a clamp assembly, a nail gun, and a nail gun kit, which can solve the problems of inconvenience in carrying and frequent replacement caused by having a large number of functional heads.

[0007] The technical solution adopted by this utility model to solve its problem is:

[0008] A collet assembly for mounting on the nozzle or nozzle slide of a nail gun, comprising:

[0009] The base head includes a base head mounting part and a functional head assembly part, wherein the base head mounting part is used to connect to the nail gun;

[0010] The functional head includes a connecting part and a functional part for clamping a corresponding pipe clamp, wherein the connecting part is detachably assembled to the functional head assembly part.

[0011] Furthermore, the functional head assembly is provided with an annular groove.

[0012] Furthermore, the functional head is made of a flexible material.

[0013] Furthermore, the flexible material is plastic or rubber.

[0014] Furthermore, the base head is made of a wear-resistant material.

[0015] Furthermore, the base head is used for the installation of one or more of the following: saddle clamp, ceiling bracket clamp, gas hanger clamp, and conduit clamp;

[0016] The functional head is used for the installation of one or more of the following: ceiling mounting brackets, gas mounting brackets, and pressure code brackets.

[0017] Furthermore, the functional unit includes a first clamping arm and a second clamping arm, which are disposed opposite to each other for clamping the pipe clamp between the first clamping arm and the second clamping arm.

[0018] Furthermore, the first clamping arm has a first stepped surface on the side facing the second clamping arm, and the second clamping arm has a second stepped surface on the side facing the first clamping arm. The first stepped surface and the second stepped surface are used to abut against the pipe clamp.

[0019] Furthermore, the functional head assembly is frustum-shaped, the connecting part of the functional head is sleeved on the functional head assembly, and the connecting part and the functional head assembly are interference-fitted.

[0020] This utility model also provides a nail gun, comprising:

[0021] A gun body, wherein the gun body has a muzzle, or the gun body has a muzzle and a muzzle slide;

[0022] Chuck assembly;

[0023] Wherein, when the gun body has the muzzle, the chuck assembly is mounted on the muzzle;

[0024] When the gun body has both the muzzle and the muzzle slide, the chuck assembly is mounted on the muzzle slide.

[0025] The clamp assembly is the clamp assembly described above.

[0026] This utility model also provides a nail gun kit, including:

[0027] A gun body, wherein the gun body has a muzzle, or the gun body has a muzzle and a muzzle slide;

[0028] Chuck assembly;

[0029] Wherein, when the gun body has the muzzle, the chuck assembly is mounted on the muzzle;

[0030] When the gun body has both the muzzle and the muzzle slide, the chuck assembly is mounted on the muzzle slide.

[0031] The chuck assembly is the chuck assembly described above;

[0032] The functional head has multiple parts, used to hold pipe clamps of different sizes or types;

[0033] One of the multiple functional heads is selectively mounted on the base head.

[0034] In summary, the clamp assembly, nail gun, and nail gun kit provided by this utility model have the following technical effects:

[0035] 1. Because the functional head can be detachably connected to the base head, and the base head and functional head work together, the base head does not need to integrate the corresponding functional components of the functional head. This allows the base head to be designed in a smaller size, making it suitable for installing pipe clamps such as saddle clamps, gas clamps, and conduit clamps. The functional head can effectively clamp pipe clamps with flat sidewalls, such as those used for clamping, ensuring stable support on both sides of the nail hole and guaranteeing stability and accuracy during nailing.

[0036] In the above-mentioned use of the base head alone, as well as the combined use of the base head and the functional head, it can be adapted to the assembly of many types of pipe clamps commonly used on the market, that is, to achieve the effect of one head for multiple uses, thereby reducing the number of functional heads to carry and the burden of carrying them. In addition, it can also reduce the frequency of functional head replacement and improve work efficiency.

[0037] 2. When the functional head is made of flexible material, the flexible material usually has a low density, that is, the functional head made of flexible material is lighter. For technicians who need to frequently change or carry multiple functional heads, this reduces the workload and improves portability.

[0038] 3. When the functional head is made of flexible material, the clamping effect and clamping efficiency can be improved because the relative position between the functional head and the clamped pipe clamp is fixed by clamping.

[0039] 4. The base head and functional head adopt a detachable assembly method, providing a structural basis for the independent operation of the base head and for the combined use of the functional head and the base head. When the functional head is made of flexible material, the functional head can quickly and easily complete the interference fit with the base head, thereby greatly improving the efficiency of assembly and disassembly between the base head and the functional head.

[0051] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0052] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0053] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0055] See Figures 1-10 This utility model discloses a clamp assembly for mounting on the nozzle or nozzle slide of a nail gun. The clamp assembly includes a base head 1 and a functional head 2. The base head 1 includes a base head mounting part 11 and a functional head assembly part 12. The base head mounting part 11 is used to connect the nail gun. The functional head 2 includes a connecting part 21 and a functional part 22 for clamping a corresponding pipe clamp. The connecting part 21 is detachably mounted to the functional head assembly part 12.

[0056] Specifically, the chuck assembly is used to mount on the nozzle or nozzle slide of a nail gun. When the nail gun has a nozzle slide at the front of the nozzle, the chuck assembly is mounted on the nozzle slide; when the nail gun does not have a nozzle slide or the nozzle slide is not located at the front of the nozzle, the chuck assembly can be optionally mounted on the nozzle to complete the auxiliary positioning function during nail firing. (Refer to...) Figures 1-3As shown, the chuck assembly includes a base head 1 and a functional head 2. The base head mounting part 11 is used to connect to the nail gun, ensuring that the entire chuck assembly can be firmly connected to the nail gun for effective nailing. The functional head assembly part 12 is used to assemble the functional head 2 to accommodate more pipe clamps of different sizes and types. The connecting part 21 can be easily connected to or separated from the functional head assembly part 12 on the base head 1. Correspondingly, the detachable connection between the connecting part 21 and the functional head assembly part 12 allows for quick replacement of different functional heads 2 according to different work requirements in practical applications, further improving the adaptability of the chuck assembly. The functional part 22 is used to clamp the type of pipe clamp that can be clamped, specifically pipe clamps whose outer walls on opposite sides are flat, such as the clamping clip 8. By clamping the flat surface of this type of pipe clamp by the functional part 22, a stable clamping force is provided during nailing, ensuring the accuracy and efficiency of the work.

[0057] Correspondingly, when the base head 1 is used alone, it can be used for the installation of the saddle clip 4, ceiling bracket clip, gas hanging clip 5 and conduit cable clip 6. The nailing installation can be completed by directly aligning the base head 1 with the nail hole of the above clips.

[0058] When functional head 2 is used on base head 1, it can be used for the installation of ceiling brackets, gas hangers 5, and clamping clips 8. During the installation of the ceiling bracket, the outer wall of functional head 2 fits snugly against the inner wall of the ceiling bracket, meaning the gap between them is minimal. Therefore, by inserting functional head 2 into the ceiling bracket, precise installation of the ceiling bracket can be achieved. Similarly, during the installation of the gas hanger 5, the outer wall of functional head 2 fits snugly against the inner wall of the gas hanger 5, meaning the gap between them is minimal. Therefore, by inserting functional head 2 into the gas hanger 5, precise installation of the gas hanger 5 can be achieved. During the installation of the clamping clip 8, functional head 2 can clamp the clamping clip 8, thus positioning functional head 2 relative to the clamping clip 8, facilitating subsequent nailing installation.

[0059] The above structure is based on the adaptation principle of different pipe clamps:

[0060] Horse riding card 4:

[0061] Specific reference Figure 4 As shown, due to its size, the universal head 3 in the market will interfere with the protrusion of the saddle clip 4 when the nail outlet is aligned with the nail hole of the saddle clip 4 in most small-sized saddle clips. This prevents the universal head 3 from fitting snugly against the nail hole of the saddle clip 4, thus compromising nailing accuracy. In this embodiment, refer to... Figure 5 As shown, by adopting a small-sized design for the base head 1, the small-sized base head 1 can be aligned and fitted with the nail hole of the saddle card 4 without interference between the base head 1 and the saddle card 4.

[0062] Ceiling bracket and gas clamp 5:

[0063] Specific reference Figure 6 As shown, the ceiling bracket and gas clamp 5 have similar basic structures and functions. However, the universal head 3 on the market has a large gap between its outer surface and the inner surface of the ceiling bracket / gas clamp 5 during use, making it impossible to accurately drive the nail into the nail hole in the middle of the ceiling bracket / gas clamp 5. For the corresponding information, please refer to... Figure 7 As shown, generally, adaptation can only be achieved by replacing the universal head 3 whose outer diameter corresponds to the inner diameter of the ceiling bracket / gas clamp 5. This results in the need to carry multiple sizes of universal heads 3, and to replace different sizes of universal heads 3 to adapt to different inner diameters of the ceiling bracket / gas clamp 5. In this embodiment, refer to... Figure 8 As shown, the ceiling bracket / gas hanger 5 can be provided with a bottom circular groove 7 on its bottom surface, so that the base head 1 can correspond to the bottom circular groove 7 of the ceiling bracket / gas hanger 5, thereby reducing the gap between the base head 1 and the wall surface that needs to be assisted in positioning and improving the accuracy of nailing.

[0064] Of course, when the inner diameter of the ceiling bracket / gas hanger 5 corresponds to the outer diameter of the functional head 2, that is, when the functional head 2 is inserted into the ceiling bracket / gas hanger 5, the outer wall of the functional head 2 fits against the ceiling bracket / gas hanger 5, so that after the functional head 2 is inserted into the ceiling bracket / gas hanger 5, the relative position of the functional head 2 and the ceiling bracket / gas hanger 5 can be kept stable, thereby improving the accuracy of nailing.

[0065] Conduit clip 6:

[0066] Specific reference Figure 9 As shown, since the conduit clip 6 has two relatively flat sides, it is generally installed using a clamping head. However, the size of the clamping head 8 differs from that of the conduit clip 6, and therefore cannot be directly adapted to the conduit clip 6. In this embodiment, similarly, the base head 1 can directly correspond to the circular groove 7 at the bottom of the conduit clip 6, allowing the base head 1 to correspond to the circular groove 7 at the bottom of the conduit clip 6 seat. This reduces the gap between the base head 1 and the wall surface that requires auxiliary positioning, improving the accuracy of nailing.

[0067] Of course, if the width of the conduit clip 6 can be stably clamped by the functional head 2, the functional head 2 can also be assembled on the base head 1, and the conduit clip 6 can be precisely installed by clamping it with the functional head 2.

[0068] Forced Code Card 8:

[0069] Specific reference Figure 10As shown, in this embodiment, a functional head 2 is detachably mounted on the base head 1. The functional head 2 has a functional part 22 for clamping the code card 8. By clamping the code card 8 through the functional part 22, the nozzle positioning during the assembly of the code card 8 is achieved.

[0070] In some embodiments, the functional unit 22 includes a first clamping arm 221 and a second clamping arm 222, which are disposed opposite to each other for clamping the tube clamp between the first clamping arm 221 and the second clamping arm 222.

[0071] It should also be noted that in some gun bodies, the base 1 can also be the muzzle itself.

[0072] For details, please refer to Figures 1-3 As shown, the first clamping arm 221 and the second clamping arm 222 are arranged opposite to each other, forming a space between the first clamping arm 221 and the second clamping arm 222 to accommodate the pipe clamp. When the functional head 2 is installed on the base head 1 and operated, the first clamping arm 221 and the second clamping arm 222 can apply clamping force to the pipe clamp from both sides to ensure that the pipe clamp remains stable during the nailing process.

[0073] Of course, when using the functional unit 22 for nailing, it is not limited to the installation of the clamping card 8. Any other device that can be clamped and fixed by the first clamping arm 221 and the second clamping arm 222, and whose nail gun nozzle corresponds to the nail hole of the tube clamp, is not limited here.

[0074] In some embodiments, the first clamping arm 221 is provided with a first step surface 223 on the side facing the second clamping arm 222, and the second clamping arm 222 is provided with a second step surface 224 on the side facing the first clamping arm 221. The first step surface 223 and the second step surface 224 are used to abut against the tube clip.

[0075] For details, please refer to Figures 1-3 As shown, the first stepped surface 223 and the second stepped surface 224 are used to abut against the upper surface of the pipe clamp. When the first clamping arm 221 and the second clamping arm 222 clamp the pipe clamp, the first stepped surface 223 and / or the second stepped surface 224 can provide a stable support point. This ensures that the pipe clamp receives additional support from the bottom when clamped, thereby greatly enhancing the overall clamping effect and the stability of the relative posture of the nail gun and the pipe clamp.

[0076] Furthermore, based on the good support provided by the first step surface 223 and / or the second step surface 224, the operator does not need to exert effort to maintain the relative position between the nail gun and the pipe clamp when performing nailing operations. That is, even in some more complex construction environments, the operator can complete the work more easily, reducing the time wasted and potential errors caused by adjusting posture.

[0077] In some embodiments, the functional head assembly portion 12 is frustum-shaped, the connecting portion 21 of the functional head 2 is sleeved on the functional head assembly portion 12, and the connecting portion 21 and the functional head assembly portion 12 are interference-fitted.

[0078] For details, please refer to Figures 1-3 As shown, the frustum-shaped design has a natural guiding effect, making it easier for the connecting part 21 of the functional head 2 to be found and accurately aligned with the position of the functional head assembly part 12. During installation, the operator does not need to align it very precisely to smoothly fit the connecting part 21 onto the functional head assembly part 12.

[0079] Furthermore, the functional head assembly part 12 includes a guide part and a mounting part. The guide part is frustum-shaped and is used for guiding the functional head 2 during the assembly process. The mounting part is column-shaped and is used for interference fit fixing of the functional head 2. That is, during the installation process of the functional head 2, the functional head 2 is inserted by the guide part and guided to the mounting part by the frustum-shaped guide part. When the functional head 2 moves to the mounting part, the functional head 2 and the mounting part are interference fit.

[0080] More importantly, the end of the base head 1 furthest from the base head mounting part 11 has a smaller diameter. This structure ensures accurate nailing during the installation of gas clamps 5 and conduit clamps 6, as the base head 1 can be directly inserted into the circular groove at the bottom of these clamps. The smaller diameter end avoids mismatch problems caused by excessive size, improving operational flexibility and accuracy. The end closer to the base head mounting part 11 maintains a larger diameter, facilitating connection with the nail gun nozzle. This thicker design not only provides stronger connection force but also ensures the strength and stability of the entire structure, preventing damage or loosening during high-intensity use.

[0081] In some embodiments, the functional head assembly 12 is provided with an annular groove 13.

[0082] For details, please refer to Figures 1-3 As shown, the annular groove 13 is located on the functional head assembly part 12, which can provide an additional anti-slip positioning effect, so that when the connecting part 21 of the functional head 2 is fitted onto the functional head assembly part 12, the connection between the two is tighter and less prone to loosening.

[0083] In some embodiments, the functional head 2 is made of a flexible material.

[0084] Specifically, flexible materials typically have a lower density, meaning that the functional head 2 made of flexible materials is lighter in weight. This reduces the workload and improves portability for technicians who need to frequently change or carry multiple functional heads 2.

[0085] More importantly, the flexible material allows the first clamping arm 221 and the second clamping arm 222 to undergo elastic deformation within a certain range. When the first clamping arm 221 and the second clamping arm 222 are subjected to external forces (such as clamping pipe clamps of different sizes), the first clamping arm 221 and the second clamping arm 222 can deform slightly to adapt to different pipe clamp sizes and shapes. This allows one functional head 2 to adapt to multiple types of pipe clamps, reducing the need for specialized tools. Furthermore, due to the elasticity of the flexible material, the first clamping arm 221 and the second clamping arm 222 can provide appropriate clamping force, neither damaging the pipe clamp due to excessive tightness nor causing unstable clamping due to excessive looseness. Especially for pipe clamps with slight differences in size but within a certain range, the flexible material functional head 2 can better meet the needs.

[0086] Furthermore, the flexible material allows for an interference fit between the connecting portion 21 of the functional head 2 and the mounting portion 12 of the functional head 2. This fit not only ensures stability after installation but also simplifies the installation and disassembly process due to the material's inherent flexibility. Operators can complete assembly or disassembly without applying excessive force, reducing operational difficulty. Moreover, the flexible material possesses good wear resistance and fatigue resistance, making it less prone to damage or wear even after repeated installation and disassembly, thus extending the service life of the functional head 2.

[0087] Furthermore, the flexible material is either plastic or rubber.

[0088] Specifically, whether requiring high strength support or high elasticity adaptability, plastic and rubber materials can meet the requirements, enabling the clamp assemblies to cope with various pipe clamp types and working environments. Furthermore, plastic and rubber molding processes are relatively mature, facilitating low-cost production.

[0089] Functional head 2 can be made of engineering plastics such as polyamide (nylon, PA) and polyoxymethylene (POM), as well as thermoplastic elastomers such as thermoplastic polyurethane (TPU) and thermoplastic vulcanizate (TPV). These materials not only possess sufficient mechanical strength to maintain stable clamping force and prevent pipe clamp slippage, but also have good elasticity and wear resistance, enabling them to adapt to pipe clamps of various sizes. Furthermore, they are chemically stable, possessing excellent weather resistance and resistance to chemical corrosion, ensuring long-term durability and reliability. Of course, other flexible materials can also be used, as long as they can guarantee strength and clamping stability while also ensuring lightweight and ease of operation; no specific limitations are imposed here.

[0090] In some embodiments, the base head 1 is made of a wear-resistant material.

[0091] Specifically, the base head 1 is made of wear-resistant material, preferably a hard metal, which leverages the high strength and excellent wear resistance of the material to ensure that the base head 1 is not easily worn during prolonged use and frequent operation, thereby extending its service life and reducing maintenance costs. Simultaneously, the good chemical stability and corrosion resistance of the wear-resistant material enable the base head 1 to maintain stable performance in various working environments, ensuring the accuracy and reliability of nail driving operations and improving overall work efficiency and user experience. Through optimized structural design and surface treatment technology, the durability and adaptability of the base head 1 are further enhanced, making it a key guarantee for the reliable operation of the chuck assembly.

[0092] This utility model also provides a nail gun, including a gun body and the above-mentioned chuck assembly. The gun body has a nozzle, or the gun body has a nozzle and a nozzle slide. When the gun body has a nozzle, the chuck assembly is installed on the nozzle. When the gun body has both a nozzle and a nozzle slide, the chuck assembly is installed on the nozzle slide.

[0093] Specifically, when the gun body does not have a nozzle slide, the base head mounting part 11 is connected to the nozzle. When the gun body has both a nozzle and a nozzle slide, the base head mounting part 11 is connected to the nozzle slide, and the connecting part 21 is detachably connected to the connecting part 21 of the functional head 2. The nail outlet of the nozzle corresponds to the nail outlet hole of the chuck assembly, so that when the nail is ejected from the nozzle, it can be accurately ejected from the nail outlet hole. When the base head 1 is assembled with the nozzle slide, the nail outlet of the nozzle, the nail outlet of the nozzle slide, and the nail outlet hole of the chuck assembly correspond to each other, so that when the nail is ejected from the nozzle, the nail passes through the nozzle slide and the chuck assembly in sequence to complete the nailing. Correspondingly, in the use of the nail gun, the functional head 2 can be disassembled to accommodate most types and sizes of pipe clamps on the market, greatly improving the convenience for operators.

[0094] This utility model also provides a nail gun assembly, including a gun body, a base head 1, and multiple functional heads 2. The gun body has a nozzle, or the gun body has a nozzle and a nozzle slide. When the gun body has a nozzle, a chuck assembly is mounted on the nozzle; when the gun body has both a nozzle and a nozzle slide, the chuck assembly is mounted on the nozzle slide; the chuck assembly is the aforementioned chuck assembly; multiple functional heads 2 are provided for holding pipe clamps of different sizes or types; one of the multiple functional heads 2 is selectively mounted on the base head 1.

[0095] Specifically, the base head mounting part 11 is connected to the nozzle of the gun body, and the connecting part 21 is detachably connected to the connecting part 21 of the functional head 2. The nail ejection nozzle of the nozzle corresponds to the nail ejection hole of the chuck assembly, so that when the nozzle ejects a nail, it can be accurately ejected from the nail ejection hole. When the base head 1 is assembled on the nozzle slide sleeve, the nail ejection port of the nozzle, the nail ejection port of the nozzle slide sleeve, and the nail ejection hole of the chuck assembly correspond, so that when the nozzle ejects a nail, the nail passes through the nozzle slide sleeve and the chuck assembly in sequence to complete the nailing. Multiple functional heads 2 may include functional heads 2 of different sizes and materials, which are not limited here. In the use of the nail gun, by removing and replacing the functional heads 2, it can adapt to most types and sizes of pipe clamps on the market, greatly improving the convenience of operators.

[0096] It should also be noted that multiple functional heads 2 can be selectively installed on the base head 1 to adapt to different pipe clamps through different functional heads 2.

[0097] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
