Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1-3 As shown, this embodiment discloses an integrated cantilever nail magazine support structure for a nail gun, including a gun body assembly 1, a nail magazine 2 detachably mounted on the gun body assembly 1, and a support base 3 connecting the gun body assembly 1 and the nail magazine 2. The nail magazine 2 has an axially extending nail storage cavity 21, and the side wall of the nail storage cavity 21 is provided with a guide groove 22 parallel to the axial direction. A nail-pushing mechanism 4 for automatic nail feeding is slidably disposed in the guide groove 22. The support base 3 is provided with a receiving slot 31 that forms an insertion fit with the bottom of the nail magazine 2. The side wall of the receiving slot 31 has an inlet notch 32 to avoid the passage of the nail-pushing mechanism 4. One side of the receiving slot 31 extends upward to form a connecting base plate 33, and the top of the connecting base plate 33 has a horizontal extension towards the gun body assembly 1. The cantilever support beam 34 extends. The gun body assembly 1 includes a gun body frame formed by the mating of a left shell 11 and a right shell 12, and a locking fastener 5. The bottom of the gun body frame has a fitting cavity 13 that matches the shape of the cantilever support beam 34. The fitting cavity 13 is provided with a positioning base 14. The positioning base 14 has a horizontally extending snap-fit ​​groove 14a for the locking fastener 5 to be inserted. The fitting cavity 13 is provided with a limiting protrusion 15 that is opposite to the positioning base 14 and can abut against the locking fastener 5 after the left shell 11 and the right shell 12 are mated. The end of the cantilever support beam 34 is provided with a locking hole 34a that matches the locking fastener 5. The support base 3 and the gun body assembly 1 are detachably fixed by fasteners 6 passing through the locking hole 34a and the locking fastener 5 in sequence.

[0023] The support base 3 serves as the mechanical transmission hub between the nail magazine 2 and the gun body assembly 1, and its core function is to bear the impact load distribution and structural positioning. The receiving slot 31 contacts the bottom circumferential surface of the nail magazine 2 to prevent the nail magazine 2 from slipping under high-frequency impact. The guide notch 32 is used to form a receiving space to avoid interference between the nail pushing mechanism 4 and the support base 3 when assembling the nail rack.

[0024] The locking fastener 5 is engaged with the snap-fit ​​groove 14a to form an interference fit. After the left housing 11 and the right housing 12 are aligned, the locking fastener 5 abuts against the limiting protrusion 15. The self-locking effect prevents the locking fastener 5 from coming out when subjected to axial impact. The fastener 6 achieves a rigid connection between the support base 3 and the gun body assembly 1.

[0025] The operating procedure for this support structure in actual operation is as follows:

[0026] Nailing stage: the nail pushing mechanism 4 is pushed to the guide chute 22 to the introduction gap 32, and the row of nails is loaded into the nail storage cavity 21 from the bottom of the nail storage cavity 21. After the nails are hit out one by one, the nail pushing mechanism 4 pushes the nails to move along the guide chute 22 to the gun nozzle direction;

[0027] Impact conduction: the axial impact force generated during the nailing operation is transmitted to the socket 31 through the bottom of the nail magazine 2, and the load is shunted to the cantilever support beam 34 and the gun body frame by the connecting base plate 33. The upwardly extending connecting base plate 33 effectively reduces the cantilever effect of the nail magazine 2 and improves the structural strength against deformation under continuous impact working conditions;

[0028] Maintenance disassembly: after the fastener 6 is loosened, the locking of the support seat 3 and the gun body assembly 1 is released, the left shell 11 and the right shell 12 are disassembled, the limiting protruding column 15 is separated from the abutment with the locking piece 5, the locking piece 5 is taken out from the clamping groove 14a, and then the support seat 3 is pulled out from the bottom of the nail magazine 2, so that the support seat 3 is quickly separated. At this time, the nail magazine 2 or the nail pushing mechanism 4 can be maintained.

[0029] As shown in Figure 4 , in the present embodiment, the inner wall of the socket 31 is in clearance fit with the bottom of the nail magazine 2, and a plurality of protruding and interference-fitting convex rib strips 31a are arranged on the inner wall of the socket 31.

[0030] The socket 31 is wrapped on four sides and is in clearance fit with the bottom of the nail magazine 2, a plurality of convex rib strips 31a are formed between the socket 31 and the bottom of the nail magazine 2 to form multi-point support, the frictional contact surface when the socket 31 is inserted into the bottom of the nail magazine 2 is reduced, and the insertion and pulling of the support seat 3 is more labor-saving. When an axial impact occurs, the convex rib strips 31a are elastically deformed under extrusion, can absorb micro-vibration with an amplitude of 0.05-0.1 mm, and can also reduce the stress concentration coefficient of the root of the nail magazine 2.

[0031] Further, a triangular reinforcing rib 34b connected with the connecting base plate 33 is arranged on the lower end surface of the cantilever support beam 34.

[0032] The reinforcing rib 34b and the cantilever support beam 34 are integrally formed by casting, and the reinforcing rib 34b is used to improve the bending stiffness of the cantilever support beam 34 as a whole and to improve the stiffness of the connection between the cantilever support beam 34 and the connecting base plate 33.

[0033] Further, as shown in Figure 2 , the positioning base 14 and the limiting protruding column 15 are both circumferentially provided with a reinforcing rib 14b connected with the gun body frame.

[0034] The impact force of continuous nailing is conducted to the connecting base plate 33 by the nail magazine 2, and then is shunted to the cantilever support beam 34 by the connecting base plate 33, and is conducted to the positioning base 14 and the limiting boss 15 by the locking piece 5 connected thereto. Therefore, the reinforcing rib 14b is mainly used to improve the strength and rigidity of the positioning base 14 and the limiting boss 15, so as to prevent the breakage and deformation thereof.

[0035] Further, the locking piece 5 is made of alloy steel or ceramic material. The high-frequency vibration of long-time continuous nailing can cause the locking end surface (such as the threaded matching surface) matched with the locking piece 5 and the fastener 6 to be worn. The alloy steel or ceramic material is used to improve the wear resistance of the locking piece 5. After the locking piece 5 is worn, the fastener 6 will be loose and needs to be replaced in time. The alloy steel or ceramic material makes the replacement cost of the locking piece 5 lower.

[0036] Further, as shown in the figure, Figure 3 The pushing mechanism 4 is provided with a limiting end 41 capable of abutting against the upper end surface of the support seat 3.

[0037] When the row of nails in the nail magazine 2 is finished, the operator can push the pushing mechanism 4 to the end of the nail magazine 2 until the limiting end 41 abuts against the upper end surface of the support seat 3, so as to load the nails. The operation of the operator is clearly prompted, the operation process is simplified, the safety hazard is reduced, and the work efficiency and safety are improved.

[0038] Further, as shown in the figure, Figure 2 The cantilever support beam 34 is in a hollow shape, and a plurality of longitudinal support plates 34c are arranged in the inside thereof.

[0039] The hollow arrangement of the cantilever support beam 34 reduces the load at the bottom of the gun body assembly 1, so as to avoid too much burden on the operator. The plurality of longitudinal support plates 34c in the inside of the cantilever support beam 34 ensure the support and bending strength thereof.

[0040] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or adopt similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
