Abstract
Description
Technical Field
[0001] This utility model relates to the field of nail gun technology, and in particular to a nail gun clamping device. Background Technology
[0002] Nail guns are modern nail fastening technology products widely used in construction. They can instantly drive nails into the substrate. Safety nail guns generally use gunpowder or high-pressure gas to fire nails, which are then driven directly into the substrate such as steel structures, non-ferrous metals, composite materials, walls, concrete, or rock, thereby firmly connecting the components that need to be fixed together.
[0003] During the use of a nail gun, depending on the needs of various construction scenarios, the firing nozzle of the nail gun may need to be pointed downwards to fire the nail. In this case, the nail is prone to falling out of the nail gun. It is necessary to pre-fix the nail inside the nail gun to ensure that the nail will not fall out during construction. It is also necessary to ensure that the nail will not deviate when entering the target object.
[0004] Especially in my country's highly developed marine engineering, mineral processing, chemical, sewage treatment, and confined space installation, nails are very easy to slip off and get lost and cannot be retrieved. Existing nail guns lack a device for pre-fixing the nails. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a nail clamping device that can clamp nails in the nail gun, and the nail installation is very convenient and quick, with high work efficiency.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a nail clamping device, including a clamping seat connected to the nail tube of a nail gun, the clamping seat having a channel for placing the nail, the channel communicating with the inner cavity of the nail tube, at least two radially extending locking holes being provided on the outer wall of the channel, the locking holes communicating with the channel, a locking ball being installed in the locking hole, a clamping assembly for pressing the locking ball against the nail being installed on the clamping seat, and a limiting device for limiting the insertion depth of the nail being provided in the channel.
[0007] As a preferred technical solution, the locking hole is provided with a first limiting step to prevent the locking ball from entering the channel.
[0008] As a preferred technical solution, the inner diameter of the locking hole is not less than the diameter of the locking ball, and the diameter of the locking ball is greater than the depth of the locking hole.
[0009] As a preferred technical solution, the clamping seat is provided with a groove corresponding to the locking hole, and the clamping assembly is installed in the groove.
[0010] As a preferred technical solution, the clamping assembly includes an elastic ring, which is installed in the sink groove. The inner diameter of the elastic ring is not greater than the outer diameter of the clamping seat at the bottom wall of the sink groove, and the inner wall of the elastic ring is clamped to the locking ball.
[0011] As a preferred technical solution, the clamping assembly includes a retaining spring with an opening on one side, the retaining spring being installed in the recess and clamped to the locking ball.
[0012] As a preferred technical solution, the locking hole is provided with no less than two and is coaxially distributed, and the clamping seat is provided with two parallel cut surfaces corresponding to the position of the locking hole; the snap ring includes an arc-shaped part, and the two ends of the arc-shaped part are connected to straight parts that respectively cooperate with the two cut surfaces, and the free end of the straight part is provided with an inwardly bent anti-disengagement hook.
[0013] As a preferred technical solution, the limiting device includes a second limiting step disposed on the inner wall of the channel.
[0014] As a preferred technical solution, one end of the clamping seat is equipped with the nail, and the other end of the clamping seat is threadedly connected to the nail tube.
[0015] As a preferred technical solution, the clamping seat and the nail tube are an integral structure.
[0016] Due to the adoption of the above technical solution, the nail clamping device includes a clamping seat connected to the nail tube of the nail gun. The clamping seat has a channel for placing the nail, which communicates with the inner cavity of the nail tube. At least two radially extending locking holes are provided on the outer wall of the channel, communicating with the channel. A locking ball is installed in each locking hole. A clamping assembly is installed on the clamping seat to press the locking ball against the nail. A limiting device is provided in the channel to restrict the insertion depth of the nail. When no nail is inserted, the locking ball is held in place by the clamping assembly. Under pressure, the nail moves into the channel, and part of the locking ball enters the channel. During use, the nail is inserted from the opening end of the channel. The nail pushes the locking ball outwards, causing the clamping component to elastically deform. Simultaneously, the elastic force of the clamping component presses the locking ball against the nail, thus fixing the nail in place within the channel. This prevents the nail from falling out during nailing operations. The nail installation process is very convenient; simply inserting the nail completes the installation, greatly improving work efficiency. It also enables nail positioning, preventing the nail from slipping or shifting, ensuring vertical installation, and guaranteeing construction quality. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0028] like Figure 1 , Figure 2 and Figure 3As shown, the nail clamping device includes a clamping seat 21 connected to the nail tube 12 of the nail gun. The clamping seat 21 has a channel 22 for placing the nail 11. The channel 22 communicates with the inner cavity of the nail tube 12. At least two radially extending locking holes 31 are provided on the outer wall of the channel 22. The locking holes 31 communicate with the channel 22. A locking ball 32 is installed in the locking hole 31. A clamping assembly is installed on the clamping seat 21 to press the locking ball 32 against the nail 11. A limiting device for limiting the insertion depth of the nail 11 is provided in the channel 22.
[0029] When no nail 11 is inserted into the channel 22, the locking ball 32 moves into the channel 22 under the pressure of the clamping assembly, and part of the locking ball 32 enters the channel 22. During use, the nail 11 is inserted from the open end of the channel 22. The nail 11 pushes the locking ball 32 outward, causing the clamping assembly to undergo elastic deformation. Simultaneously, the elastic force of the clamping assembly presses the locking ball 32 against the nail 11, thus fixing the nail 11 within the channel 22. This prevents the nail 11 from falling out during nailing operations. The nail 11 installation process is very convenient; simply inserting it completes the installation, greatly improving work efficiency. It also enables nail 11 positioning, preventing slippage and displacement, ensuring vertical installation of the nail 11, and guaranteeing construction quality.
[0030] In one specific embodiment, a first limiting step 33 is provided in the locking hole 31 to prevent the locking ball 32 from entering the channel 22. If no limiting device is provided in the locking hole 31, when no nail 11 is inserted into the channel 22, the locking ball 32 will slide into the channel 22 under the elastic force of the clamping assembly. The first limiting step 33 can restrict the radial movement freedom of the locking ball 32, so that a part of the locking ball 32 can slide into the channel 22 along the locking hole 31 to achieve the function of clamping the nail 11, without moving excessively and falling into the channel 22.
[0031] According to one embodiment of the present invention, the inner diameter of the locking hole 31 is not less than the diameter of the locking ball 32, which can ensure that the locking ball 32 can slide in the locking hole 31; the diameter of the locking ball 32 is greater than the depth of the locking hole 31, so that the locking ball 32 can squeeze the nail 11 inward and squeeze the clamping assembly outward.
[0032] In one specific embodiment, a recess 34 is provided on the clamping base 21 corresponding to the locking hole 31, and the clamping assembly is installed in the recess 34. The recess 34 has a limiting function for the clamping assembly, which can prevent the clamping assembly from shifting along the axial direction of the clamping base 21.
[0033] According to one embodiment of the present invention, the clamping assembly includes an elastic ring (not shown in the figure), the elastic ring is installed in the sink 34, the inner diameter of the elastic ring is not greater than the outer diameter of the clamping seat 21 at the bottom wall of the sink 34, and the inner wall of the elastic ring is clamped to the locking ball 32. The elastic ring can be made of rubber and is fitted onto the clamping seat 21 outside the locking ball 32 during installation through elastic deformation. The inner diameter of the elastic ring is less than or equal to the outer diameter of the clamping seat 21 at the countersunk groove 34. When the inner diameter of the elastic ring is less than the outer diameter of the clamping seat 21 at the countersunk groove 34, the elastic ring will apply a certain pressure to the locking ball 32 even without inserting the nail 11. When the inner diameter of the elastic ring is equal to the outer diameter of the clamping seat 21 at the countersunk groove 34, after inserting the nail 11, the nail 11 pushes the elastic ring outward, and the elastic ring deforms, which will also apply a certain pressure to the locking ball 32, thereby applying a certain pressure to the nail 11, thus achieving the clamping and locking of the nail 11.
[0034] As one specific implementation method, such as Figure 4 As shown, the clamping assembly includes a retaining spring 4 with an opening on one side. The retaining spring 4 is installed in the recess 34 and is clamped to the locking ball 32. The retaining spring 4 applies a spring force to the locking ball 32 pointing towards the channel 22, which can compress the locking ball 32 into the channel 22, thereby pressing the locking ball 32 against the outer wall of the nail 11, thus achieving the locking of the nail 11.
[0035] In actual production, the clamping component can be a snap ring 4, or a spring ring, or other structural forms that can achieve the clamping function. Any alternative that can be easily conceived by those skilled in the art can be used.
[0036] According to one embodiment of the present invention, such as Figure 4 , Figure 5 and Figure 6 As shown, the locking hole 31 has at least two holes and is coaxially distributed. The clamping seat 21 has two parallel cut surfaces 35 corresponding to the position of the locking hole 31. The snap ring 4 includes an arc-shaped part 41. The two ends of the arc-shaped part 41 are connected to straight parts 42 that respectively cooperate with the two cut surfaces 35. The free end of the straight part 42 is provided with an inwardly bent anti-disengagement hook 43. The cut surface 35 is a plane, and the cut surface 35 cooperates with the straight part 42 to ensure that the straight part 42 of the snap ring 4 contacts the locking ball 32 and ensures that pressure can be applied to the locking device. The two straight parts 42 are symmetrically arranged at both ends of the arc-shaped part 41. The arc-shaped part 41 drives the straight part 42 to press the locking ball 32. When the nail 11 is inserted, the nail 11 pushes the locking ball 32 outward. The arc-shaped part 41 undergoes elastic deformation and drives the straight part 42 to adapt and adjust to the locking ball 32. The anti-disengagement hook 43 can prevent the snap ring 4 from falling off the clamping seat 21 during operation.
[0037] The clamping seat 21 may also be provided with three or more locking holes 31, and a locking ball 32 is installed in each locking hole 31. All the locking holes 31 and locking balls 32 are evenly distributed around the channel 22 in the circumference, so that the locking balls 32 can apply pressure to the nail 11 in a uniform circumference.
[0038] In one specific embodiment, the limiting device includes a second limiting step 23 disposed on the inner wall of the channel 22. The second limiting step 23 limits the depth to which the nail 11 is inserted into the channel 22.
[0039] According to one embodiment of the present invention, such as Figure 7 As shown, the nail 11 is mounted on one end of the clamping seat 21, and the other end of the clamping seat 21 is threadedly connected to the nail tube 12. The clamping seat 21 is connected to the nail tube 12 by threads, and the clamping seat 21 can be assembled with minor modifications to the nail tube 12, resulting in low modification costs. When this nail clamping device is damaged, it can simply be removed and a new one installed, and the nail tube 12 can continue to be used.
[0040] As one specific implementation method, such as Figure 8 As shown, the clamping base 21 and the nail gun tube 12 are an integral structure. The integral structure of the clamping base 21 and the nail gun tube 12 improves the overall strength, eliminates the assembly process during use, and improves work efficiency.
[0041] The clamping seat 21 and the nail gun tube 12 adopt the following... Figure 7 The split structure shown is convenient for maintenance and replacement, while the integrated structure has higher overall strength. The appropriate structure can be selected according to actual needs.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
