Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic mosquito nail guns, and in particular relates to a full-automatic pneumatic mosquito nail gun nail clip. Background Art

[0002] Pneumatic mosquito nail guns are widely used in small woodworking, furniture manufacturing and fastening of craft products. At present, the fully automatic mosquito nail guns are widely used in the market, and their nail clamps are structures that can automatically adjust the nail length; there are mainly four types of pneumatic mosquito nail guns with different nail lengths, namely: 1) P616 mosquito nail gun, its nail length is 5mm, 8mm, 12mm, 15mm, 16mm; 2) P622 mosquito nail gun, its nail length is 12mm, 15mm, 18mm, 20mm, 22mm; 3) P625 mosquito nail gun, its nail length is 12mm, 15mm, 18mm, 20mm, 22mm, 25mm; 4) P630 mosquito nail gun, its nail length is 12mm, 15mm, 18mm, 20mm, 22mm, 25mm, 30mm.

[0003] Please see attached Figure 1 Taking the P622 mosquito nail gun as an example, the position of nails of different lengths is limited by the top head and four pins on the movable nail clamp body; when using a 12mm nail, the top head pushes the nail forward under the action of the spring; when using a 15mm nail, the top head and the adjacent 12-speed pins push the nail together, and the next-speed pin is limited; then as the length of the nail increases, and so on, the pins automatically adjust the nailing height.

[0004] However, in actual applications, when binding thinner structures, 8mm or even 6mm nails are required, and the P616 mosquito nail gun will be used. However, the nail clip of this model of mosquito nail gun is not a fully automatic nail clip and cannot automatically adjust the binding height, which is inconvenient to use. Figure 1 It can be seen that the movable nail clamp body of the aforementioned P622 mosquito nail gun does not have sufficient width below the top head to provide a groove for accommodating a shorter length of the stick and the top head. If the height of the movable nail clamp body is increased, the height of the fixed nail clamp body must also be increased accordingly to match the movable nail clamp body. This will increase the manufacturing cost of the nail clamp, increase the weight of the nail clamp, and make it inconvenient to use.

[0005] Therefore, it is necessary to redesign a fully automatic pneumatic nail gun nail clip to meet the requirements of nailing with a shorter length without increasing the manufacturing cost of the nail clip too much. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a fully automatic pneumatic mosquito nail gun nail clamp, so as to avoid the problem that the existing fully automatic pneumatic mosquito nail gun cannot meet the demand for shorter nailing length, thereby achieving the effect of increasing the coverage range of nailing length without excessively increasing the manufacturing cost of the nail clamp.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A fully automatic pneumatic nail gun nail clamp comprises a fixed nail clamp and a movable nail clamp, wherein the fixed nail clamp comprises a fixed nail clamp body, a nail guide plate and a nail dividing plate, wherein the nail guide plate and the nail dividing plate are fixedly connected and installed at the front end of the fixed nail clamp body; the movable nail clamp comprises a movable nail clamp body, a top head, a plurality of inserts and a plurality of springs.

[0009] The movable nail clamp body is vertically provided with a transverse groove on the side surface along the length direction thereof, and the fixed nail clamp body is slidably installed in the transverse groove and forms a gap for accommodating gun nails between the fixed nail clamp body and the movable nail clamp body; a plurality of spaced limiting grooves are vertically provided on the bottom wall of the transverse groove along the height direction of the movable nail clamp body, and each limiting groove penetrates the two end surfaces of the movable nail clamp body along the length direction of the movable nail clamp body; the top head and each insertion stick are slidably connected to the corresponding limiting grooves from bottom to top in sequence, and each spring is arranged in the limiting groove one by one and correspondingly supports the top head and each insertion stick.

[0010] To further improve the above technical solution, strip grooves are vertically opened on the side of the fixed nail clamp body close to the transverse groove at the positions corresponding to the limit grooves, and each strip groove longitudinally penetrates the two end faces of the fixed nail clamp body; each insertion stick extends into each strip groove one by one on the side close to the fixed nail clamp body.

[0011] Furthermore, the limiting groove is composed of a circular groove with a circular inner cross section and a rectangular groove with a rectangular outer cross section, and the diameter of the circular groove is greater than the width of the rectangular groove;

[0012] The parts of the plug and each of the insertion sticks located in the circular groove have a cylindrical part matched with the circular groove.

[0013] Furthermore, the top head includes a sheet-shaped vertical section, and the vertical section is located between the fixed nail clamp body and the movable nail clamp body;

[0014] The middle part of the vertical section horizontally extends toward the limiting groove and is bent to form the cylindrical part.

[0015] Furthermore, the number of the plurality of sticks is 6.

[0016] Furthermore, an L-shaped rear baffle is provided at the rear end of the movable nail clamp body, and the transverse plate portion of the rear baffle is closely arranged with the rear end surface of the movable nail clamp body;

[0017] Each spring is compressed in the limiting groove between the rear end of the cylindrical part and the rear baffle.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The utility model is a fully automatic pneumatic nail gun nail clamp, which is no longer the original structure in which a fixed nail clamp body is enclosed by a movable nail clamp body, but a transverse groove is opened on the side of the movable nail clamp body, so that the fixed nail clamp body can be slidably arranged in the transverse groove; in this way, the structure in which the movable nail clamp body is enclosed by the fixed nail clamp body is adopted, and the entire bottom wall of the transverse groove can be used to open a limit groove to install plugs of different gears to cover the nailing length below 12mm (6mm and 8mm), so as to meet multiple nailing lengths as much as possible without excessively raising the material cost of the entire nail clamp.

[0020] 2. The utility model is a fully automatic pneumatic nail gun nail clamp, in which the inner end of the limit groove is designed to be circular, and the free ends of the parts of the top head and each plug-in located in the limit groove are correspondingly designed to be compatible cylindrical parts, so that the top head and each plug-in can be stuck in the limit groove but can slide in the limit groove; because when assembling and assembling, the top head, each plug-in and each spring must be installed on the movable nail clamp body first, and then the top head and each plug-in are aligned with the corresponding strip grooves on the fixed nail clamp body, and the sliding installation cooperation between the movable nail clamp body and the fixed nail clamp body is carried out; if the top head and each plug-in are not stuck in the limit groove, the top head and each plug-in will pop out under the action of the spring, which is inconvenient to install.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figure 2-Figure 5 A fully automatic pneumatic nail gun nail clamp of a specific embodiment includes a fixed nail clamp and a movable nail clamp, wherein the fixed nail clamp includes a fixed nail clamp body 11, a nail guide plate 12 and a nail dividing plate 13, wherein the nail guide plate 12 and the nail dividing plate 13 are fixedly connected and installed at the front end of the fixed nail clamp body 11; the movable nail clamp includes a movable nail clamp body 2, a top head 3, a plurality of inserts 4 and a plurality of springs 6,

[0034] The movable nail clamp body 2 is vertically provided with a transverse groove 201 on the side surface along its length direction, and the fixed nail clamp body 11 is slidably installed in the transverse groove 201 and forms a gap for accommodating gun nails between the fixed nail clamp body 11 and the movable nail clamp body 2; a plurality of spaced limiting grooves 202 are vertically provided on the bottom wall of the transverse groove 201 along the height direction of the movable nail clamp body 2, and each limiting groove 202 passes through the two end surfaces of the movable nail clamp body 2 along the length direction of the movable nail clamp body 2; the top head 3 and each insertion stick 4 are slidably connected to the corresponding limiting groove 202 from bottom to top in sequence, and each spring 6 is arranged one by one in the limiting groove 202 and correspondingly supports the top head 3 and each insertion stick 4.

[0035] A fully automatic pneumatic nail gun nail clamp of the embodiment is no longer the original structure in which the fixed nail clamp body 11 is wrapped around the movable nail clamp body 2, but a transverse groove 201 is opened on the side of the movable nail clamp body 2, so that the fixed nail clamp body 11 is slidably arranged in the transverse groove 201; in this way, the structure in which the movable nail clamp body 2 is wrapped around the fixed nail clamp body 11 is adopted, and the bottom wall of the entire transverse groove 201 can be used to open a limiting groove 202 to install a plug 4 of different gears to cover the nailing length below 12mm (6mm and 8mm), so as to meet multiple nailing lengths as much as possible without excessively raising the material cost of the entire nail clamp.

[0036] See also Figure 2 and Figure 5 , wherein, a strip groove 1101 is vertically opened on the side of the fixed nail clamp body 11 close to the transverse groove 201 at the position corresponding to each limit groove 202, and each strip groove 1101 longitudinally penetrates the two end surfaces of the fixed nail clamp body 11; each insertion stick 4 extends into each strip groove 1101 one by one on one side close to the fixed nail clamp body 11.

[0037] In this way, one side of the insertion rod 4 is located in the limiting groove 202 of the movable nail clamp body 2, and the other side is located in the strip groove of the fixed nail clamp body 11;

[0038] See also Figure 5 , wherein the limiting groove 202 is composed of a circular groove with a circular inner cross section and a rectangular groove with a rectangular outer cross section, and the diameter of the circular groove is greater than the width of the rectangular groove;

[0039] The parts of the plug 3 and the plugs 4 located in the circular groove have a cylindrical portion 5 that matches the circular groove.

[0040] During the assembly, the top head 3, the plugs 4 and the springs 6 need to be installed in the limiting groove 202 of the movable nail clamp body 2 first, and then the top head 3 and the plugs 4 are aligned with the corresponding strip grooves on the fixed nail clamp body 11, so as to perform the sliding assembly cooperation between the movable nail clamp body 2 and the fixed nail clamp body 11; the limiting groove 202 is specifically designed into the above-mentioned structure, and the parts of the top head 3 and the plugs 4 located in the limiting groove 202 correspond to the circular groove and the rectangular groove, so that the top head 3 and the plugs 4 can slide back and forth along the length direction of the limiting groove 202 without falling off laterally.

[0041] See also Figure 5-Figure 7 , wherein the head 3 includes a sheet-shaped vertical section 301, and the vertical section 301 is located between the fixed nail clamp body 11 and the movable nail clamp body 2;

[0042] The middle portion of the vertical section 301 extends horizontally toward the limiting groove 202 and is bent to form the cylindrical portion 5 .

[0043] Thus, since the fully automatic pneumatic nail gun nail clamp of the utility model is provided with 6mm and 8mm nailing heights, the head 3 originally used to push the 12mm nail forward needs to be shortened to accommodate the 6mm nail, but in order to make enough space on the transverse groove 201 to open the limit groove 202, the cylindrical portion 5 on the head 3 is designed to extend horizontally in the middle of the vertical section 301 and then be bent, rather than Figure 1 The upper end of the middle plug 3 is horizontally extended and then bent.

[0044] See also Figure 5 , wherein the number of the plurality of plugs 4 is 6.

[0045] During implementation, from bottom to top, they are 6-speed plug-in, 8-speed plug-in, 12-speed plug-in, 15-speed plug-in, 18-speed plug-in and 22-speed plug-in. Each gear position here corresponds to limiting the position of the corresponding length of the nail; for example, when a 6mm nail is loaded into the nail clamp, the top head 3 pushes the nail forward under the action of the spring, and the 6-gear plug above the top head 3 limits the vertical position of the nail of this length; when an 8mm nail is loaded into the nail clamp, the top head 3 and the 6-gear plug push the nail forward under the action of the spring, and the 8-gear plug above the 6-gear plug limits the position of the nail; and when the length of the nail is 25mm, the top head 3 and the 6 plugs push the nail of this length forward together; by analogy, the nail clamp structure of the utility model can cover the nailing lengths of 6mm, 8mm, 12mm, 15mm, 18mm, 22mm and 25mm currently available on the market.

[0046] Here, the innovativeness of the structural design of the movable nail clamp body 2 enclosing the fixed nail clamp body 11 in the utility model is further described. Figure 1On this basis, the limit grooves 202 are opened on the fixed nail clamp body 11, and the structure of the fixed nail clamp body 11 outsourcing the movable nail clamp body 2 continues to be adopted, which seems to be able to solve the problem of setting 6-speed and 8-speed plug-in sticks without changing the height of the nail clamp. However, if the limiting groove 202 is provided on the fixed nail clamp body 11, then each spring 6, the top head 3 and each insertion stick will also be installed on the fixed nail clamp body 11. When such a structure is nailed, it is necessary to first clamp a row of nails between the nail guide plate 12 and the top head 3 (and the insertion stick 4), and it is necessary to first compress the spring 6 corresponding to the top head 3 (and the insertion stick 4) to a suitable position, and then install the nail, which is very inconvenient; while the structure of the fully automatic pneumatic mosquito nail gun nail clamp of the utility model, when nailing, it is only necessary to slide the movable nail clamp backward to make room for nailing, and then put the nail into the fixed nail clamp body 11, and then slide the movable nail clamp forward to abut and close with the nail plate 13, and the spring 6 corresponding to the top head 3 (and the insertion stick 4) can be automatically compressed, which is convenient for nailing and improves work efficiency.

[0047] from Figure 1 and Figure 5 It can be seen that, whether it is the P622 mosquito nail gun or the present embodiment, the width of each inserting stick 4 including the top head 3 is staggered in length, and correspondingly, the depth of each limiting groove 202 on the movable nail clamp body 2 is also staggered in depth. This is to ensure that the top head 3 and each inserting stick 4 can be installed in place through the cooperation of the cylindrical portion 5 and the inner end of the limiting groove 202, and enough gears can be set to cover different nailing lengths; therefore, in the movable nail clamp body 2 with limited height, the circular inner ends of each limiting groove 202 are staggered, and the widths of the corresponding inserting sticks 4 are adapted.

[0048] See also Figure 3 and Figure 4 , wherein the rear end of the movable nail clamp body 2 is provided with an L-shaped rear baffle plate 7, and the transverse plate portion of the rear baffle plate 7 is closely arranged with the rear end surface of the movable nail clamp body 2;

[0049] Each spring 6 is compressed in the limiting groove 202 between the rear end of the cylindrical portion 5 and the rear baffle 7 .

[0050] When implementing, see Figure 4 and Figure 8 First, load nails of the required length (a row of nails) into the nail clamp, the nails are located in the gap between the fixed nail clamp body 11 and the movable nail clamp body 2, the springs 6 corresponding to the top head 3 and the inserted skewer 4 of the required gear will be compressed and support the nails, and the springs 6 corresponding to the remaining inserted skewer 4 will be in the initial state; then close the fixed nail clamp and the movable nail clamp and install them on the nail gun 8; when nailing, each time a nail is driven out, the top head 3 and the inserted skewer 4 will push the nail forward under the action of the spring 6, the nail is subjected to balanced force, and it is not easy to get stuck when nailing.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
