Description

Technical Field

[0001] This utility model belongs to the field of fastening tool technology, specifically relating to a positioning slide assembly, a special nail slide mechanism, and a fastening tool. Background Technology

[0002] Common fastening tools, such as nail guns, are fastening tools that use nails as fasteners and nozzles as the output end (or firing component) of the fastener. They are mostly used in construction and home renovation. A nail gun uses a drive motor and 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 to move, which in turn drives the firing pin mounted on the piston to strike and eject the nail, thus achieving nailing.

[0003] During the renovation process, nails may need to be driven into specific areas depending on the user's needs. For example, a recessed area may be created on the target object (wall or wood panel). To facilitate positioning, existing nail guns typically have a sliding sleeve attached to the nozzle, and this sleeve is movable to allow for adjustment of the penetration depth. However, because the current sliding sleeve is fitted outside the nozzle, its lateral dimension is wider than the nozzle width. Since the nozzle itself has a certain width, the sleeve is not easy to insert into smaller areas (such as the aforementioned recessed area), making it inconvenient to use. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a positioning slide assembly for fastening tools that facilitates nailing, a special nail slide mechanism, and a fastening tool.

[0005] The present invention adopts the following technical solution:

[0010] The positioning sleeve assembly for fastening tools proposed in this utility model also has the following feature: the adjusting member has an adjusting rod, which is rotatable and detachably mounted on the mounting base via a thread.

[0011] The positioning slide sleeve assembly for fastening tools proposed in this utility model also has the following feature: the slide sleeve component has a connecting part for connecting the main body and the positioning part, and the inner side surface where the connecting part is connected to the main body has an abutting surface for abutting against the end face of the actuating component.

[0012] The positioning sleeve assembly for fastening tools proposed in this utility model also has the following feature: the positioning part has a connecting portion integrally connected with the connecting part, and the end of the connecting portion away from the connecting part forms a positioning surface for abutting against the target object.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the fastening accessory positioning component of this utility model will be specifically described below in conjunction with the embodiments and accompanying drawings.

[0030] <Example 1>

[0031] This embodiment provides a positioning slide sleeve assembly for a fastening tool and a fastening tool, wherein the fastening tool can be a nail gun 100, such as... Figure 1 As shown, the nail gun 100 includes a tool body 20 and a positioning slide assembly 30. The front end of the tool body 20 is provided with an actuation component 21 and a nail magazine (not shown in the figure) for storing nails. The actuation component 21 is fixed to the front side of the tool body 20 by a mounting part 23, and has a nozzle for firing nails and a cover plate 22 covering the nozzle. An actuation channel for nails to pass through is formed between the nozzle and the cover plate 22. The positioning slide assembly is installed at the nozzle and is used to abut against the target object (usually a wall or wooden board, etc.) or insert into the target object for positioning. The nailing depth can be adjusted by adjusting the distance between the outer end of the nozzle and the target nailing position.

[0032] like Figure 1 and Figure 2 As shown, the positioning sliding sleeve assembly 30 in this embodiment is a positioning sliding sleeve assembly for a fastening tool, which is disposed on the actuation component 21 of the fastening tool. It includes a mounting base 31, an adjusting member 32, a sliding sleeve component 33, and a return spring 34. The mounting base 31 is fixedly mounted on the cover plate 22 of the actuation component 21. The adjusting member 32 is movably disposed on the mounting base 31. One end of the sliding sleeve component 33 protrudes from the front end of the cover plate 22 of the actuation component, and the other end is combined with the adjusting member 32.

[0033] Specifically, such as Figure 3As shown, the bottom of the mounting base 31 is a flat mounting plate 311, which is fixed to the end of the cover plate 22 near the tool body 20 by screws or bolts, and fixed above the cover plate 22. The mounting base 31 extends upward from the front end of the mounting plate 311 to form a mounting piece 312. A return spring 34 is installed between the rear end face of the mounting piece 312 (i.e., the side facing the tool body 20) and the mounting part 23. The adjusting component 32 includes an adjusting rod 321 and an adjusting knob 322. The mounting piece 312 has a through hole for the adjusting rod 321 to pass through axially, and the through hole has an internal thread. The corresponding outer circumference of the adjusting rod 321 has an external thread. The adjusting rod 321 and the mounting piece 312 are connected by a thread, so that the adjusting rod 321 can rotate relative to the mounting piece 312. The adjusting rod 321 is located at the rear end of the mounting plate 312 and passes through the return spring 34. An adjusting knob 322 is fixed on the outer periphery of the front side of the adjusting rod 321 and the outer periphery of the adjusting knob 322 is distributed with several anti-slip stripes. By rotating the adjusting knob 322, the adjusting rod 321 is driven to rotate. Under the action of the thread, the adjusting rod 321 can move back and forth axially relative to the mounting base 31.

[0034] The front end of the adjusting rod 321 extends through the adjusting knob 322 for mounting the sliding sleeve component 33. An annular groove 3211 is formed circumferentially at the junction of the front end of the adjusting rod 321 and the sliding sleeve component 33. The rear end of the sliding sleeve component 33 forms a sliding sleeve mating part 331 that engages with the front end of the adjusting rod 321. A mating hole 3311 is provided in the middle of the sliding sleeve mating part 331 for the front end of the adjusting rod 321 to extend into. A limiting round rod 3312 is also laterally provided on the sliding sleeve mating part 331. The circumference of the limiting round rod 3312... A portion of the part is exposed within the mating hole 3311. The limiting rod 3312 allows one side of this exposed portion to be embedded in the annular groove 3211. This ensures that the sliding sleeve component 33 does not rotate with the adjusting rod 321 during rotation. However, as the adjusting rod 321 moves back and forth along the axial direction, the sliding sleeve component 33 can move back and forth with it, thereby adjusting the relative distance between the sliding sleeve component 33 and the end face of the excitation component 21, and thus adjusting the penetration depth when the nail gun is used for nailing.

[0035] The adjusting member 32 also includes a limiting part formed by the combination of the limiting spring 323 and the limiting ball 324, such as Figure 3As shown, the adjusting knob 322 has a limiting mounting groove 3221 along the axial direction. A limiting spring 323 and a limiting ball 324 are sequentially installed in the limiting mounting groove 3221. The limiting spring 323 abuts against the bottom of the limiting mounting groove 3221 and the limiting ball 324. Under the action of the limiting spring 323, a portion of the limiting ball 324 can protrude from the opening of the limiting mounting groove 3221. During the rotation of the adjusting rod 321 and the adjusting knob 322, the limiting ball 324... The exposed portion of the sliding sleeve will roll or slide along the side end face of the sliding sleeve mating part 331 facing the adjusting knob 322, reducing rotational resistance. Simultaneously, a positioning groove 3313 adapted to the limiting ball 324 is also provided on the side end face of the sliding sleeve mating part 331 facing the adjusting knob 322. After rotating to a certain angle, the exposed portion of the limiting ball 324 can be embedded in the positioning groove 3313, thus creating a relatively stable state between the sliding sleeve component 33 and the adjusting component. In this embodiment, as... Figure 5 As shown, four positioning grooves 3313 are provided, evenly and circumferentially arranged on the outer periphery of the mating hole 3311. That is, starting with the limiting ball 324 engaging one of the positioning grooves 3313, and then rotating the adjustment knob 322 to 90 degrees, the limiting ball 324 will engage the next positioning groove 3313. A sound is emitted when the limiting ball 324 engages the positioning groove 3313, indicating to the user that it has been adjusted to the correct position. In practice, more positioning grooves 3313 can be provided. The angle between the positioning grooves 3313 can be calculated based on the distance required for actual nailing, thus determining the number and angular position of the positioning grooves 3313.

[0036] like Figures 1-5 As shown, the sliding sleeve component 33 also has a main body 332, a positioning part 333, and a connecting part 334. The main body 332 is in the shape of a long, rectangular sleeve, and is slidably fitted onto the outer periphery of the front end of the cover plate 22 of the firing component. A pair of guide grooves 3321 are formed on the inner walls of both sides of the main body 332 for engaging with guide protrusions on the sides of the cover plate 22. The rear end of the main body 332 extends upward to form the sliding sleeve mating part 331. The front end of the main body 332 tapers inward to form the positioning part 333, and the main body 332 and the positioning part 333 are connected as one unit by a stepped connecting part 334, which is larger at one end and smaller at the other. The positioning part 333 is used to abut against or insert into the target object for positioning. A nail-penetrating channel 330 is formed in the middle of the positioning part 333 and the connecting part 334 for the nail to pass through and be ejected. Figure 3 As shown, vertically, the main body 332, the positioning part 333, and the connecting part 334 are all located below the sliding sleeve mating part 331, as... Figure 1As shown, when the positioning sliding sleeve assembly 30 is installed on the cover plate 22, the main body 332 is sleeved on the outer periphery of the cover plate 22, the positioning part 333 and the connecting part 334 are located on the front side of the front end of the cover plate 22, and the sliding sleeve mating part 331, the adjusting part and the mounting seat are all located above the cover plate 22.

[0037] The main body 332 is fitted around the outer periphery of the cover plate 22, therefore its lateral dimension is at least greater than the lateral dimension (i.e., cross-sectional width) of the cover plate 22. The positioning part 333 is formed by the inward reduction of the main body 332, therefore the lateral dimension (i.e., cross-sectional width) of the positioning part 333 is smaller than the cross-sectional width of the main body 332. In this embodiment, as... Figure 2 As shown, the positioning part 333 is cylindrical, as... Figure 4 As shown, the main body 332 has a square groove cross-section that opens downwards, while the positioning part 333 has a circular cross-section, the diameter of which is smaller than the opening width of the square groove. During operation, the positioning part 333 rests against the target object; therefore, as... Figure 7 As shown, the reduced-size positioning part 333 can extend into a smaller target area (such as a recess on a wall), making nailing easier.

[0038] In practice, the positioning part 333 can also be the same square sleeve shape as the main body part 332. In this case, the cross-section of the main body part 332 is a square groove cross-section with an opening facing downwards, and the cross-section of the positioning part 333 is a square cross-section. The width of the square cross-section is smaller than the groove width of the square groove cross-section.

[0039] like Figure 3 and Figure 4 As shown, the inner side of the connecting part 334 where it connects to the main body part 332 also has an abutment surface 3341 that can be used to abut against the end face of the excitation component (i.e., the front end face of the cover plate 22). By adjusting the adjusting member, the distance between the abutment surface 3341 and the front end face of the cover plate 22 can be adjusted, thereby adjusting the nailing distance between the front end face of the cover plate 22 and the target object. When adjusted so that the front end face of the cover plate 22 abuts exactly against the abutment surface 3341, the nailing distance between the front end face of the cover plate 22 and the target object is minimized during the nailing process.

[0040] The positioning part 333 has a connecting portion 3331 integrally connected to the connecting part 334. One end of the connecting portion 3331 away from the connecting part 334 forms a positioning surface for abutting against the target object. Figures 2-6As shown, in this embodiment, a plurality of pointed tips 3332 that can be inserted into the target object are formed at the end of the connecting portion away from the connecting portion 334. One end of the pointed tip 3332 is sharp, and the other end is connected to the end face of the connecting portion 3331. In use, the tip of the pointed tip 3332 can abut against the surface of the target object, or even be inserted into the interior of the target object, thereby positioning the nailing position. The surface where the pointed tip 3332 finally contacts the surface of the target object is the positioning surface.

[0041] <Example 2>

[0042] Based on Embodiment 1 above, the adjusting rod 321 and the mounting plate 312 are still detachably connected. At least two adjusting components and sliding sleeve components 33 are provided, and the size and shape of the sliding sleeve components 33 can be set to be different. When it is necessary to adapt to nails of different sizes or models, the adjusting rod 321 can be removed by rotating the adjusting knob 322. At this time, the sliding sleeve component 33 will be removed together. Then, the sliding sleeve component 33 and the adjusting component corresponding to the nail can be installed to complete the replacement, which is very convenient.

[0043] <Example 3>

[0044] This embodiment proposes a special nail sliding sleeve mechanism for fastening tools and a fastening tool. The fastening tool can be a nail gun for firing special nails. The nail gun includes a tool body and a special nail sliding sleeve mechanism. The special nail sliding sleeve mechanism includes a special nail and a sliding sleeve assembly. The sliding sleeve assembly is a positioning sliding sleeve assembly as described in Embodiment 1 or 2 above. Refer to the appendix in Embodiment 1. Figure 1 The front end of the tool body is provided with an actuation component and a nail box for storing special nails. The actuation component is fixed to the front side of the tool body by a mounting part and has a nozzle for firing nails and a cover plate covering the nozzle. An actuation channel for nails to pass through is formed between the nozzle and the cover plate. A positioning slide assembly is installed at the nozzle and is used to abut against the target (usually a wall or wooden board) or insert into the target for positioning. The nailing depth can be adjusted by adjusting the distance between the outer end of the nozzle and the target nailing position.

[0045] The special nail in this embodiment is a double-headed nail, such as... Figure 8 As shown, the double-headed nail includes a nail body 11, which has an embedded section 111 and an exposed section 112. One end of the embedded section 111 is pointed to form a nail tip 12, and the other end is provided with a fastening cap 13 protruding from the surface of the embedded section 111 in a convex ring shape. One end of the exposed section 112 is connected to the fastening cap 13, and the other end forms a nail head 14. Figure 9As shown, when the special nail is driven into the target object 10, the embedded section 111 is inserted into the target object 10, while the exposed section 112 and the fastening cap 13 are exposed outside the target object 10, which can be used to hang items. The advantages of this double-cap nail are that it is easy to pull out, can be reused, avoids damage to the target object, saves manpower and resources, reduces costs, and can also achieve the dual functions of fixing and suspending objects.

[0046] When driving in these special nails, ordinary nail guns, due to the lack of a sliding sleeve or an inappropriate sleeve length, cannot accurately control the striking distance between the nail gun and the target object. If the striking distance is too close, the fastening cap 13 may also be driven into the target object, potentially damaging the surface during later removal. Therefore, using the positioning sliding sleeve assembly in Embodiment 1 or Embodiment 2 can effectively adjust the striking distance, thus solving this problem.

[0047] To better accommodate double-cap nails, the axial distance between the abutment surface 3341 at the junction of the connecting part 334 and the main body 332 and the positioning surface on the positioning part 333 can be set to be greater than or equal to the axial distance between the nail head 14 and the fastening cap 13 (i.e., the length of the double-cap nail exposed after being driven into the wall). In other words, when the sliding sleeve part 33 is adjusted so that the front end face of the cover plate 22 is exactly abutting the abutment surface 3341, the nailing distance between the front end face of the cover plate 22 and the target object is minimized during the nailing process. As long as this minimum distance is greater than or equal to the axial distance between the nail head 14 and the fastening cap 13, it can be ensured that the fastening cap 13 will not sink into the target object when the double-cap nail is driven into it, so that the target object will not be damaged when the double-cap nail is removed later.

[0048] 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.
