Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a hard-tube glue gun which is convenient for disassembling and assembling a glue cylinder. Background Art

[0002] Glue is used for bonding between two objects. There are many kinds of glue on the market at present. When using glue for splicing seams, since the width of the seams is generally relatively small, a glue gun is always used. Classified by the packaging of the glue, it can be divided into hard-packaged glue and soft-packaged glue at present; among them, the hard-packaged glue is the barrel-packed glue, which means that the packaging of the glue is completed by a hard glue cylinder; while the soft-packaged glue is commonly known as sausage-packed glue, which means that the packaging of the glue is a soft plastic bag type. In order to cooperate with the barrel-packed glue, a hard-tube glue gun is designed. However, the structure of the existing hard-tube glue gun is relatively complex. When installing, fixing and using the glue cylinder, it has to cooperate with a glue-supporting rack, and both the installation and disassembly are relatively troublesome and not very convenient to use. Content of the Utility Model

[0003] Based on this, in view of the problems existing in the existing hard-tube glue gun, it is necessary to provide a hard-tube glue gun which is convenient for disassembling and assembling a glue cylinder, has a simple structure, is simple to install and disassemble, and is convenient to use.

[0004] A hard-tube glue gun which is convenient for disassembling and assembling a glue cylinder includes: a gun body having an accommodating cavity, a glue cylinder fixing mechanism connected to the gun body, a fixed handle fixedly connected to the gun body, a movable handle hinged to the fixed handle, a push rod movably penetrating through the gun body and the glue cylinder fixing mechanism, a push plate spring and a push plate sleeved on the push rod and located in the accommodating cavity; the glue cylinder fixing mechanism includes a hollow fixed pipe seat connected to the gun body, a support pipe located inside the fixed pipe seat, a guide sleeve passing through the support pipe, a ring-shaped elastic piece and a support spring sequentially sleeved on the outer wall of the support pipe, the support spring is located on the side of the ring-shaped elastic piece close to the gun body, and the guide sleeve abuts against the side of the ring-shaped elastic piece far from the support spring; a top cap is installed at one end of the push rod close to the fixed pipe seat, and the top cap is arranged opposite to the side of the ring-shaped elastic piece far from the support spring.

[0005] When the above-mentioned rigid tube glue gun facilitating the disassembly and assembly of the glue cylinder is in use, first pull the push rod to the initial position, and then push the glue cylinder filled with glue (one end is open and the other end is equipped with a glue outlet nozzle) into the fixed tube seat through the opening until the end of the glue cylinder abuts against the annular elastic sheet, causing it to elastically deform inward. Then, the end of the glue cylinder crosses the outer edge position of the annular elastic sheet. At this time, the outer edge of the annular elastic sheet abuts against the inner wall of the glue cylinder and applies an outward elastic force to it. At the same time, the outer wall of the glue cylinder also abuts against the inner wall of the fixed tube seat, thereby fixing the glue cylinder in the fixed tube seat. Moreover, the support spring can ensure that the annular elastic sheet will not become loose from the inside of the glue tube. When it is necessary to disassemble the glue tube from the fixed tube seat, pull it backward through the push rod until the top cap abuts against the outside of the annular elastic sheet. As it is further pulled backward, the annular elastic sheet retracts inward under the extrusion of the top cap, so that the outer edge of the annular elastic sheet disengages from the inner wall of the glue cylinder to release the clamping. Then, the glue cylinder can be pulled out and disassembled from the fixed tube seat. This rigid tube glue gun facilitating the disassembly and assembly of the glue tube forms a simple clamping structure through the cooperation of the fixed tube seat and the annular elastic sheet. The installation and disassembly of the glue cylinder are simple and convenient to use.

[0006] In one embodiment, it further includes a strong spring installed between the fixed handle and the movable handle, and both ends of the strong spring abut against the fixed handle and the movable handle respectively.

[0007] In one embodiment, a reinforcing piece is installed on the movable handle, and the reinforcing piece abuts against the push plate.

[0008] In one embodiment, the push rod is arranged to pass through the inside of the guide sleeve.

[0009] In one embodiment, first limiting convex rings and second limiting convex rings are respectively convexly provided at both ends of the guide sleeve. The first limiting convex ring abuts against the annular elastic sheet, and the second limiting convex ring abuts against the outer wall of the fixed tube seat.

[0010] In one embodiment, a reset ring is installed on the push rod. The reset ring is located on the side of the push plate away from the push plate spring and is connected to the gun body.

[0011] In one embodiment, a pull handle is installed at one end of the push rod away from the top cap, and the pull handle is located outside the rear end of the gun body.

[0012] In one embodiment, a hanging piece is further installed on the push rod, and the hanging piece is located on the side of the pull handle away from the gun body.

[0013] In one embodiment, the glue cylinder fixing mechanism further includes a support disc sleeved on the outer wall of the support tube, and both sides of the support disc abut against the annular elastic sheet and the support spring respectively.

[0014] In one of the embodiments, it further includes a cover plate installed on the gun body, and the cover plate is located above the push plate spring and the push plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1 to 6 , which is a schematic diagram of the rigid tube glue gun 100 facilitating the disassembly and assembly of the glue cylinder. The rigid tube glue gun 100 facilitating the disassembly and assembly of the glue cylinder includes a gun body 20 having an accommodation cavity 21, a glue cylinder fixing mechanism 30 connected to the gun body 20, a fixed handle 41 fixedly connected to the gun body 20, a movable handle 42 hinged to the fixed handle 41, a push rod 50 movably passing through the gun body 20 and the glue cylinder fixing mechanism 30, a push plate spring 51 and a push plate 52 sleeved on the push rod 50 and located in the accommodation cavity 21.

[0025] Further, the glue cylinder fixing mechanism 30 includes a fixed tube seat 31 connected to the gun body 20 and being hollow, a support tube 32 located inside the fixed tube seat 31, a guide sleeve 33 passing through the support tube 32, a circular elastic sheet 34 and a support spring 35 sequentially sleeved on the outer wall of the support tube 32. The support spring 35 is located on the side of the circular elastic sheet 34 close to the gun body 20, and the guide sleeve 33 abuts against the side of the circular elastic sheet 34 far from the support spring 35. Among them, the fixed tube seat 31, the support tube 32, the guide sleeve 33, the circular elastic sheet 34, and the support spring 35 are coaxially arranged. The circular elastic sheet 34 is integrally arranged in a frustum of a cone structure and is connected by a plurality of equally spaced feathers 341. In this embodiment, an avoidance opening 311 is provided on the fixed tube seat 31, and the avoidance opening 311 facilitates the quick pushing of the glue cylinder onto the fixed tube seat 31, wherein the avoidance opening 311 is located obliquely above the end of the fixed tube seat 31 far from the gun body 20.

[0026] Further, a top cap 53 is installed at one end of the push rod 50 close to the fixed tube seat 31, and the top cap 53 is oppositely arranged with the side of the circular elastic sheet 34 far from the support spring 35. Among them, the top cap 53 includes a pressing part 531 and a circular ring part 532 connected to the outer edge of the pressing part 531. The pressing part 531 can extrude the glue in the glue tube to extrude the glue from the glue tube, and the circular ring part 532 is oppositely arranged with the circular elastic sheet 34 and can extrude the outside of the circular elastic sheet 34 to cause it to deform.

[0027] Further, first limiting convex rings 331 and second limiting convex rings 332 are respectively protruded at both ends of the guide sleeve 33. The first limiting convex ring 331 abuts against the circular elastic sheet 34, and the second limiting convex ring 332 abuts against the outer wall of the fixed tube seat 31. Among them, the outer diameter dimensions of the first limiting convex ring 331 and the second limiting convex ring 332 are both larger than the outer diameter dimension of the support tube 32. Further, a plurality of opening slits 333 are provided on the guide sleeve 33, and the opening slits extend along the length direction of the guide sleeve 33 and the openings face the second limiting convex ring 332.

[0028] Further, the cartridge fixing mechanism 30 further includes a support disc 36 sleeved on the outer wall of the support tube 32. The two sides of the support disc 36 are respectively abutted against the annular elastic sheet 34 and the support spring 35. The support disc 36 can provide a certain outward thrust to the cartridge under the action of the support spring 35, facilitating the outward pushing of the cartridge and further improving the convenience of disassembly.

[0029] Further, the rigid tube glue gun 100 facilitating the disassembly and assembly of the cartridge further includes a strong spring 43 installed between the fixed handle 41 and the movable handle 42. The two ends of the strong spring 43 are respectively abutted against the fixed handle 41 and the movable handle 42. The strong spring 43 can provide a reset elastic force to the movable handle 42 so that the movable handle 42 can be reset immediately after completing the previous glue extrusion drive to prepare for the next glue extrusion. To protect the movable handle 42 from deformation, a reinforcing piece 44 is installed on the movable handle 42, and the reinforcing piece 44 is abutted against the push plate 52.

[0030] Further, the push rod 50 is arranged to pass through the inside of the guide sleeve 33, so that it can slide in a guided manner under the action of the guide sleeve 33. A reset ring 53 is installed on the push rod 50. The reset ring 53 is located on the side of the push plate 52 away from the push plate spring 51 and is connected to the gun body 20. The reset ring 53 can inhibit the backward movement of the push rod 50 to ensure the glue extrusion effect of each forward movement. The function of the push plate 52 is to push the push rod 50 forward, and the function of the push plate spring 51 is to return to its original position after the push plate 52 finishes pushing the push rod 50 forward each time.

[0031] Further, a pull handle 54 is installed at one end of the push rod 50 away from the top cap 53. The pull handle 54 is located outside the rear end of the gun body 20. The pull handle 54 is convenient for applying force to pull the push rod 50 backward. Further, a hanging piece 55 is also installed on the push rod 50. The hanging piece 55 is located on the side of the pull handle 54 away from the gun body 20. The hanging piece 55 is convenient for the user to place and store.

[0032] Further, the rigid tube glue gun 100 facilitating the disassembly and assembly of the cartridge further includes a cover plate 60 installed on the gun body 20. The cover plate 60 is located above the push plate spring 51 and the push plate 52.

[0033] The above hard-tube glue gun 100 facilitating the disassembly and assembly of the glue cylinder, when in use, first pull the push rod 50 to the initial position, and then push the glue cylinder filled with glue (one end is open and the other end is provided with a glue outlet nozzle) into the fixed tube seat 31 from the opening until the end of the glue cylinder abuts against the annular elastic piece 34, causing it to elastically deform inward. Then, the end of the glue cylinder crosses the outer edge position of the annular elastic piece 34. At this time, the outer edge of the annular elastic piece 34 abuts against the inner wall of the glue cylinder and applies an outward elastic force to it. At the same time, the outer wall of the glue cylinder also abuts against the inner wall of the fixed tube seat 31, thereby fixing the glue cylinder in the fixed tube seat 31. Moreover, the support spring 35 can ensure that the annular elastic piece 34 does not become loose from the inside of the glue tube. When it is necessary to disassemble the glue tube from the fixed tube seat 31, pull it backward through the push rod 50 until the top cap 53 abuts against the outer side of the annular elastic piece 34. As it is further pulled backward, the annular elastic piece 34 retracts inward under the extrusion of the top cap 53, so that the outer edge of the annular elastic piece 34 is disengaged from the inner wall of the glue cylinder to release the clamping. Then, the glue cylinder can be pulled out and disassembled from the fixed tube seat 31. This hard-tube glue gun 100 facilitating the disassembly and assembly of the glue tube forms a simple clamping structure through the combined use of the fixed tube seat 31 and the annular elastic piece 34. The installation and disassembly of the glue cylinder are simple and convenient to use.
