Nailing tool

Abstract

The utility model discloses a nailing tool which solves the problems that an iron nail at a nailing position of an existing nail gun is prone to skew, the extending direction of the iron nail does not coincide with the stroke of a firing pin, and consequently nailing skew is caused. The magnetic structure is arranged at the position, adjacent to the nailing position, of the machine body so that the iron nails conveyed to the nailing position can be corrected through the magnetic force of the magnetic structure. No matter the connection tightness between two adjacent iron nail assemblies is not enough, dislocation occurs, and when residual nails in a nail bin are few, the elastic force of an elastic element is reduced, so that nail feeding is poor. The conditions that the iron nail is inclined at the nailing position and the nail outlet and the extending direction of the iron nail does not coincide with the stroke of the striker can be avoided under any one or the common conditions of the factors that the shape of a body is distorted due to improper storage of the iron nail assembly and the iron nail is inclined due to vibration of a tool when the nailing action is executed. The device is used for accurately positioning an iron nail so that a firing pin can accurately strike the iron nail to achieve nailing.

Description

Technical Field

[0001] The utility model belongs to a nailing tool, in particular to a nailing tool which can accurately position an iron nail so that a striker can accurately strike the iron nail to realize nailing. Background Art

[0002] Existing nail gun products have the problem that the nails are skewed at the nailing position, and the extension direction of the nails does not coincide with the striker stroke, resulting in skewed nailing. The reasons for the above problems include:

[0003] 1. Each nail assembly includes several (for example, 10) nails arranged side by side. Multiple nail assemblies can be placed in the nail bin. The connection between two adjacent nail assemblies is not tight enough, and misalignment is easy to occur at the nailing position.

[0004] 2. When there are few remaining nails in the nail feeding channel, the elastic force of the elastic element is reduced, resulting in poor nail feeding.

[0005] 3. The shape of the nail assembly is distorted due to improper storage.

[0006] 4. When nailing, the vibration of the tool itself causes the nail to be skewed. This can also cause problems such as nail jamming and empty gun. Utility Model Content

[0007] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the existing nail guns that the nails are easily skewed at the nailing position and the extension direction of the nails does not coincide with the stroke of the striker, and to provide a nailing tool that can accurately position the nails so that the striker can accurately hit the nails to achieve nailing.

[0008] To achieve the above-mentioned purpose, the nailing tool of the utility model includes a nailing position arranged on a body and a firing pin and a nail magazine corresponding to the nailing position, the front end of the nail magazine faces the nailing position so that the nails in the nail magazine are transported to the nailing position, and the firing pin is movably configured to move to the nailing position to implement nailing or leave the nailing position to make way for the nails to be transported to the nailing position, and its characteristic is that a magnetic structure is arranged at a position adjacent to the nailing position on the body to use the magnetic force of the magnetic structure to align the nails transported to the nailing position.

[0009] The nailing tool is provided with a magnetic structure at a position adjacent to the nailing position on the machine body so as to use the magnetic force of the magnetic structure to align the iron nails delivered to the nailing position, thereby preventing the iron nails from being skewed at the nailing position and the nail outlet, and preventing the extension direction of the iron nails from coinciding with the stroke of the striker, so as to accurately position the iron nails so as to allow the striker to accurately strike the iron nails to achieve nailing.

[0010] Preferably, the body has a positioning portion, and the positioning portion and the nail magazine are located on both sides of the nailing position and face each other. Accordingly, the delivered nails can be positioned so that the nails face the impact direction of the striker.

[0011] Preferably, the magnetic structure is located in the positioning part. Accordingly, the magnetic force can be directed to the nail magazine, so that the magnetic force of the magnetic structure can attract the nails along the conveying direction of the nails, thereby preventing the nails from the nail magazine from being skewed due to the magnetic force deflecting the conveying direction of the nails. In particular, when the number of nails included in the nail assembly is reduced during the nailing process, the nail assembly is more likely to be skewed due to the shortening of the length of the nail assembly, and the magnetic structure located in the positioning part can overcome this defect through magnetic force.

[0012] Preferably, the shape of the positioning portion is adapted to the shape of the nail, so as to support the delivered nail and prevent the nail from being skewed.

[0013] In one embodiment, the magnetic structure is a permanent magnet or a magnetized metal fixed to the positioning part. The permanent magnet and the magnetized metal can be given the required magnetic force according to the needs. Moreover, the magnetized metal can be configured into a shape suitable for accurately attracting the iron nail, for example: the star-shaped contour of the magnetized metal matches the contour of the iron nail. Moreover, the magnetized metal can be made of a material with a better lifespan to contact the iron nail, thereby extending the service life of the magnetized metal.

[0014] Specifically, the fuselage includes a first shell and a second shell, the first shell and / or the second shell have an assembly portion, and the permanent magnet or magnetized metal is fixed to the assembly portion.

[0015] In one embodiment, the magnetic structure is a magnetic positioning part. The magnetism of the positioning part is achieved by magnetizing the positioning part. Accordingly, the magnetic structure can be directly formed on the fuselage, simplifying assembly. In addition, it is not necessary to change the structure of the product, which can save the cost of re-opening the mold in the case where a manufacturing mold is already available.

[0016] In a specific embodiment, the nailing tool is a manual tool, an electric tool or a pneumatic tool, that is, the power for driving the striker can be a manual drive device, an electric drive device or a pneumatic drive device.

[0017] Preferably, a conveying assembly is arranged in the nail bin, and the conveying assembly includes a push block and a first elastic element, and the first elastic element is used to apply a forward elastic force to the push block. Accordingly, the nail assembly in the nail bin can be pushed forward, and appropriate elastic force is provided to push the nails into place and keep the nails in a correct posture to prevent the nails from being skewed.

[0018] Preferably, the conveying assembly further includes a support plate, a guide rod, and a locking structure; the support plate and the push block are assembled on the fuselage for forward and backward movement so as to pull the support plate and the push block out of the fuselage; the guide rod is assembled on the support plate and penetrates the push block so as to allow the push block to move forward and backward along the support plate, and the first elastic element is a spiral compression spring sleeved on the guide rod; the locking structure is arranged at the rear end of the support plate and is unlockably locked with the fuselage. Accordingly, the conveying assembly can be pulled out of the nail magazine according to demand, and the nail assembly can be added to the nail magazine.

[0019] Preferably, in order to facilitate loading of the nail assembly into the nail magazine, the lock structure includes a seat and a movable lock, the seat is assembled at the rear end of the support plate, the movable lock is movably assembled on the seat, a second elastic element acts between the seat and the movable lock, and the movable lock is unlockably locked with the body by the elastic force of the second elastic element. This structure facilitates locking and unlocking.

[0020] Preferably, in order to prevent the loosening of the conveying assembly from causing the nail assembly to tilt, the seat is movably connected to the rear end of the support plate so that the seat and the support plate can move relative to each other in the front-to-back direction, and a third elastic element acts between the seat and the support plate, and the elastic force of the third elastic element causes the front end of the support plate to elastically contact the fuselage forward and the movable lock to elastically contact the locking portion of the fuselage backward. Accordingly, when the conveying assembly is loaded into the nail magazine, the support plate and the lock structure can maintain a stable position.

[0021] Preferably, the support plate is provided with a protrusion, and the fuselage is provided with a retaining edge, and when the support plate is pulled out from the fuselage, the retaining edge blocks the protrusion and limits the support plate to the fuselage. Accordingly, it is possible to avoid completely pulling the entire conveying assembly out of the nail magazine, avoid the trouble of reloading the conveying assembly, and ensure that the nail assembly is correctly loaded into the nail magazine.

[0022] Preferably, the front end of the push block is provided with a guiding slope, which gradually extends forward from top to bottom. Accordingly, when the nail assembly is loaded into the nail bin, the guiding slope can guide the nail assembly to be placed on the front side of the push block.

[0023] The utility model arranges a magnetic structure at a position adjacent to the nailing position on the machine body so as to use the magnetic force of the magnetic structure to position the iron nails delivered to the nailing position. No matter if there is a misalignment due to insufficient connection tightness between two adjacent iron nail assemblies, poor nail delivery due to reduced elastic force of the elastic element when there are few remaining nails in the nail bin, distortion of the body shape of the iron nail assembly due to improper storage, or iron nail skewing due to vibration of the tool itself when performing the nailing action, the iron nail can be prevented from being skewed at the nailing position and the nail outlet, and the extension direction of the iron nail does not coincide with the stroke of the striker, so as to accurately position the iron nail so that the striker can accurately strike the iron nail to achieve nailing.

[0041] In the description of the present utility model, it is necessary to understand that the technical features defined by the terms "first", "second" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present utility model.

[0042] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0043] Figure 1-9 FIG. 1 shows a nailing tool of an embodiment. The nailing tool comprises a nailing position 101 disposed on a body 100 and a striker 200 and a nail magazine 102 corresponding to the nailing position. Figure 5In the structure shown, the firing pin 200 is arranged vertically (up and down direction), the nail magazine 102 is arranged horizontally (front and back direction), and the nailing position 102 is located at the intersection of the up and down movement stroke of the firing pin 200 and the forward extension of the nail magazine 102. The lower side of the nailing position 102 is a nail outlet 111. Accordingly, the front end of the nail magazine 102 faces the nailing position 101 so that the nails in the nail magazine are transported to the nailing position. The firing pin 200 is movably configured to move to the nailing position to implement nailing or leave the nailing position to make way for the nails to be transported to the nailing position. In the figure, the side of the firing pin is assembled in the corresponding guide grooves 112 on the first shell and the second shell to realize its movable configuration. A magnetic structure 103 is configured on the fuselage adjacent to the nailing position to use the magnetic force of the magnetic structure to align the nails delivered to the nailing position, in order to prevent the nails from being skewed at the nailing position and the nail outlet, and the extension direction of the nail from not coinciding with the stroke of the striker, so as to accurately position the nail so that the striker can accurately hit the nail to achieve nailing.

[0044] Specifically, the fuselage 100 has a positioning portion 104, and the shape of the positioning portion 104 is adapted to the shape of the iron nail. The positioning portion 104 is located at the front side of the nailing position 102, and the nail magazine 102 is located at the rear side of the nailing position 101, and the positioning portion and the nail magazine are opposite to each other in the front-to-back direction. Moreover, the magnetic structure 103 is a permanent magnet hidden and fixed in the positioning portion, and the permanent magnet does not contact the iron nail. In other embodiments, a magnetized metal can be used instead of a permanent magnet, and when a magnetized metal is used, the magnetized metal can contact the iron nail.

[0045] In the illustrated structure, for ease of assembly, the fuselage 100 is as follows Figure 8-9 As shown, it is assembled by a first shell 105 and a second shell 106. Both the first shell and the second shell are provided with holes and grooves as the assembly part 107, and the permanent magnets are installed in the corresponding holes and grooves and are hidden.

[0046] In another embodiment, the positioning portion may be magnetized to form a magnetic structure, eliminating the need to assemble a permanent magnet or magnetized metal.

[0047] In order to facilitate loading nails into the nail magazine and conveying the nails forward, a conveying assembly 300 is configured in the nail magazine 102. The conveying assembly 300 includes a push block 301 and a first elastic element 302, and the first elastic element 302 is used to apply a forward elastic force to the push block. Specifically, the conveying assembly 300 also includes a support plate 303, a guide rod 304, and a locking structure 305. The support plate 303 and the push block 301 are assembled on the fuselage to move forward and backward to pull the support plate and the push block out of the fuselage. Specifically, a front-end closed slide groove 110 is provided on the first shell 105 and the second shell 106, and the two side edges 313 of the support plate 303 are respectively located in the corresponding slide groove 110. The guide rod 304 is penetrated through the push block 301 so that the push block can move forward and backward along the support plate, and the rear end of the guide rod 304 is assembled on the support plate 303 to maintain the assembly relationship with the support plate. The first elastic element 302 is a spiral compression spring sleeved on the guide rod 304. The lock structure 305 is arranged at the rear end of the support plate 303 and is unlockably locked with the fuselage. The lock structure shown in the figure includes a seat 306 and a movable lock 307. The seat 306 is assembled at the rear end of the support plate 303, and the movable lock 307 is movably assembled on the seat 306. A second elastic element 308 acts between the seat 306 and the movable lock 307. The movable lock 307 is unlockably locked with the fuselage by the elastic force of the second elastic element 308. The seat 306 is movably connected to the long hole 315 at the rear end of the support plate 303 through a pin shaft 314 so that the seat and the support plate can move relative to each other in the front and rear directions. A third elastic element 309 acts between the seat 306 and the support plate 303. The elastic force of the third elastic element 309 causes the front end of the side edge 313 of the support plate to elastically contact the front end of the fuselage slide groove 110 forward, and causes the movable lock 307 to elastically contact the locking portion 108 of the fuselage backward. The support plate 303 is provided with a protrusion 310, and the first shell 105 of the fuselage is provided with a retaining edge 113. When the support plate is pulled out of the fuselage, the retaining edge 113 blocks the protrusion 310 to limit the support plate to the fuselage. The front end of the push block 301 is provided with a guiding slope 312, which gradually extends forward from top to bottom.

[0048] The movement of the striker 200 depends on the power drive device. The power drive device can be a manual drive device, an electric drive device or a pneumatic drive device. When the power drive device is a manual drive device, the nailing tool is a manual tool, when the power drive device is an electric drive device, the nailing tool is an electric tool, and when the power drive device is a pneumatic drive device, the nailing tool is a pneumatic tool.

[0049] exist Figure 5In the structure shown, the power drive device is a manual drive device 400. The manual drive device 400 includes a pressure handle 401, a pry bar 402, a drive spring 403, and a fourth elastic element 404. The rear end of the pressure handle 401 is rotatably assembled on the fuselage 100 via a first shaft 405, and the middle part of the pressure handle 401 has a first groove 406 and a second groove 407. The front end of the pry bar 402 is inserted into the pry hole 201 of the striker 200, and the rear end of the pry bar 402 is configured with a second shaft 408, and the second shaft 408 is located in the first groove 406 or the second groove 407. The middle part of the pry bar 402 has a third groove 409 and a fourth groove 410, and the third groove or the fourth groove is supported by the third shaft 109 on the fuselage. The driving spring 403 is composed of a plurality of plate-shaped springs stacked together. The rear end and the middle part of the driving spring 403 are mounted on the fuselage. The front end of the driving spring 403 is connected to the striker 200 (such as being inserted into the corresponding hole at the upper end of the striker) to apply a driving force to the striker in the forward and downward direction. The fourth elastic element 404 is placed between the front end of the pressure handle 401 and the front end of the pry bar 402 to apply an elastic force to the pry bar in the forward and downward direction. Figure 5 As shown, the second shaft 408 is located in the first slot 406, the fourth slot 410 is supported by the third shaft 109, and the front end of the driving spring 403 is connected to the striker 200. When the pressing handle 401 is pressed downward relative to the fuselage, the pry bar 402 swings like a lever with the third shaft 109 as the fulcrum. During the pressing process, as the posture of the pry bar and the pressing handle changes, the striker rises to make way for the nailing position, and the pry bar moves backward ( Figure 5 The second shaft 408 at the right end of the pry bar moves from the first slot 406 to the second slot 407, and the fourth slot 410 in the middle of the pry bar is transformed from the third shaft 109 to the third slot 409, and the front end of the pry bar is disengaged from the striker. With the elastic force of the driving spring 403, the striker 200 moves downward quickly to strike the nail at the nailing position to achieve nailing. After that, the pressure handle 401 is released, and the pry bar 402 is reset to the position under the elastic force of the fourth elastic element 404. Figure 5 In this way, by pressing the pressure handle one by one, nails can be driven one by one.
