[0004] However, the overall structure of the glue gun is too bulky when in use, making it difficult to use conveniently, so there is an urgent need to provide a solution to improve the above problem. Utility Model Content

[0005] The utility model aims to provide a glue gun with thread-propelled propulsion, which is beneficial to reducing the volume of the overall equipment and can also more accurately adjust the glue output in the glue storage cylinder through the thread setting.

[0006] The utility model provides a thread-propelled glue gun, comprising a glue gun frame and a glue storage cylinder detachably arranged in the glue gun frame, the glue gun frame is provided with a threaded rod that moves toward the glue storage cylinder, and the threaded rod is threadedly rotatably arranged on the glue gun frame, the end of the threaded rod contacts the glue storage cylinder and squeezes the glue storage cylinder; when the threaded rod squeezes the glue storage cylinder, the glue storage cylinder discharges glue.

[0007] The utility model provides a thread-propelled glue gun, which makes the threaded rod on the glue gun frame to make it contact with the glue storage barrel, and squeezes the glue storage barrel as the threaded rod rotates, so that the glue storage barrel discharges glue. In this way, the glue liquid in the glue storage barrel can be discharged by rotating the threaded rod, and the glue storage barrel can be detachably arranged in the glue gun frame, which is conducive to reducing the volume of the overall equipment, and the amount of glue discharged in the glue storage barrel can be more accurately adjusted through the threaded setting.

[0008] Optionally, the glue gun rack is provided with an installation cavity, and the glue storage cylinder is detachably arranged in the installation cavity, and the side wall of the glue storage cylinder is snap-fitted with the side wall of the glue gun rack located at the installation cavity.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0024] See also Figure 1 and Figure 2 The embodiment of the utility model provides a thread-propelled glue gun, comprising a glue gun frame 1 and a glue storage cylinder 2 detachably arranged inside the glue gun frame 1. When performing glue injection, the glue storage cylinder 2 containing glue liquid is installed on the glue gun frame 1. The glue gun frame 1 fixes the glue storage cylinder 2 and facilitates the operator to hold the glue storage cylinder 2 for glue dispensing. Specifically, the glue liquid pre-stored in the glue storage cylinder 2 can be glass glue.

[0025] In fact, in actual use, a glue gun rack 1 can be used with multiple identical or different glue storage cylinders 2, so as to ensure the continuity of the glue discharging operation. When the glue in a glue storage cylinder 2 is completely squeezed out, the glue storage cylinder 2 can be replaced.

[0026] See also Figure 1 and Figure 2 The glue gun frame 1 is moved toward the glue storage cylinder 2 and is provided with a threaded rod 3, and the threaded rod 3 is threadedly rotatably arranged on the glue gun frame 1, and the end of the threaded rod 3 contacts and squeezes the glue storage cylinder 2. When the threaded rod 3 squeezes the glue storage cylinder 2, the glue storage cylinder 2 can discharge glue.

[0027] In fact, the glue gun holder 1 is cylindrical as a whole, and the threaded rod 3 is rotatably connected to the end of the glue gun holder 1, and the threaded rod 3 is coaxially arranged with the glue gun holder 1. When the threaded rod 3 is threadedly rotated at the end of the glue gun holder 1, due to the threaded connection between the threaded rod 3 and the glue gun holder 1, the rotational motion can be converted into linear motion, and the pressure applied by the end of the threaded rod 3 to the glue storage cylinder 2 can be more accurately controlled, thereby improving the accuracy of glue output control.

[0028] In fact, see Figure 2 The end of the threaded rod 3 relatively close to the rubber storage barrel 2 is semi-spherical, and the semi-spherical surface of the end contacts and squeezes the rubber storage barrel 2, which is conducive to uniformly applying force to the surface of the rubber storage barrel 2 and avoiding damage to the surface of the rubber storage barrel 2 by the threaded rod 3.

[0029] In some embodiments, see Figure 1 and Figure 2 The glue gun frame 1 is provided with a support tube 4 on the rotating side of the threaded rod 3, and the threaded rod 3 is threadedly connected in the support tube 4. The setting of the support tube 4 can improve the rotation stability of the threaded rod 3 on the glue gun frame 1. In fact, the support tube 4 and the glue gun frame 1 can be integrally formed by injection molding, so that the connection strength between the support tube 4 and the glue gun frame 1 can be improved, and the support tube 4 and the glue gun frame 1 can be prevented from being twisted off during the rotation of the threaded rod 3.

[0030] In some embodiments, see Figure 1 and Figure 2 A handle 5 is provided on the side of the threaded rod 3 relatively away from the glue storage cylinder 2, and the setting direction of the handle 5 is perpendicular to the axial direction of the threaded rod 3, so that the handle 5 and the threaded rod 3 are T-shaped as a whole, and a gripping groove 6 is formed on the side of the handle 5 close to the glue gun holder 1, so that the operator can more conveniently rotate the threaded rod 3 through the handle 5 and the matching gripping groove 6.

[0031] In some embodiments, see Figure 2 A limit ring 7 is provided between the threaded rod 3 and the support tube 4 and the handle 5, and the limit ring 7 is sleeved on the side wall of the threaded rod 3. When the threaded rod 3 rotates in the support tube 4 and undergoes linear displacement, and when the limit ring 7 conflicts with the end of the support tube 4, the maximum penetration distance of the threaded rod 3 is reached, thereby preventing the threaded rod 3 from excessively squeezing the rubber storage tube 2 and causing structural damage.

[0032] In some embodiments, see Figure 1 and Figure 2Two reinforcing ribs 8 are also provided at the connection between the glue gun holder 1 and the support tube 4. The two reinforcing ribs 8 are symmetrically arranged on two circumferential sides of the support tube 4, so that the torsion resistance of the support tube 4 can be improved when the threaded rod 3 rotates in the support tube 4. In fact, the glue gun holder 1, the support tube 4 and the reinforcing ribs 8 can be integrally formed by injection molding.

[0033] In some embodiments, see Figure 1 , Figure 2 and Figure 3 An installation cavity 9 is opened inside the glue gun rack 1, and the glue storage cylinder 2 is detachably arranged in the installation cavity 9. When the glue storage cylinder 2 is located in the installation cavity 9, the side wall of the glue storage cylinder 2 is in contact with and fits with the side wall of the glue gun rack 1 located at the installation cavity 9, thereby improving the position stability of the glue storage cylinder 2 when the glue gun rack 1 is installed.

[0034] In some embodiments, see Figure 2 and Figure 3 A disassembly opening 10 is provided on the side wall of the glue gun holder 1 at the installation cavity 9, and the disassembly opening 10 makes the installation cavity 9 open, and the installation cavity 9 can be connected with the outside through the disassembly opening 10, so that the glue storage cylinder 2 can enter the installation cavity 9 through the disassembly opening 10, or be taken out of the installation cavity 9 through the disassembly opening 10.

[0035] In fact, along the axial direction of the glue gun rack 1, the opening angle of the disassembly opening 10 on the installation cavity 9 is 180°, so that the glue gun rack 1 is semi-cylindrical as a whole, which is conducive to the cylindrical glue storage cylinder 2 entering the installation cavity 9. At the same time, the opening length of the disassembly opening 10 on the installation cavity 9 along the axial direction of the glue gun rack 1 is greater than the diagonal length of the glue storage cylinder 2, so that when the glue storage cylinder 2 is installed in the installation cavity 9, the glue gun rack 1 is not easy to interfere.

[0036] In some embodiments, see Figure 2 and Figure 3 The glue gun rack 1 is provided with N pressing plates 11 at the opening position of the disassembly port 10. When the glue storage cylinder 2 is located in the installation cavity 9, the N pressing plates 11 are clamped and abutted against the side wall of the glue storage cylinder 2; wherein N is a positive integer greater than or equal to 1.

[0037] In fact, Figure 2 Where N is 2, two clamping plates 11 are symmetrically arranged on both sides of the disassembly port 10. When the rubber storage tube 2 enters the installation cavity 9 through the disassembly port 10, the rubber storage tube 2 is squeezed between the two clamping plates 11, and the two clamping plates 11 are elastically moved away from each other. At this time, the end of the clamping plate 11 slides on the side wall of the rubber storage tube 2. When the rubber storage tube 2 enters the installation cavity 9, the clamping plate 11 fixes the position of the rubber storage tube 2.

[0038] In some embodiments, see Figure 2 and Figure 3 A disassembly hole 12 is also provided on the side wall of the glue gun holder 1 at the installation cavity 9, and the disassembly hole 12 is arranged opposite to the disassembly opening 10. When the glue storage cylinder 2 is located in the installation cavity 9, part of the side wall of the glue storage cylinder 2 is exposed in the disassembly hole 12. When the side wall installed in the glue storage cylinder 2 needs to be disassembled, the operator can push the glue storage cylinder 2 toward the disassembly opening 10 through the disassembly hole 12.

[0039] In some embodiments, see Figure 3 and Figure 4 The glue gun holder 1 is connected to the installation cavity 9 and is provided with a positioning hole 13, and the positioning hole 13 is provided on the side of the glue gun holder 1 relatively far away from the threaded rod 3, and the end of the glue storage barrel 2 is provided with a positioning column 14 which is plugged into and matched with the positioning hole 13. When the glue storage barrel 2 is installed in the installation cavity 9, the positioning hole 13 and the positioning column 14 are plugged into and matched with each other, which is beneficial to further improve the position stability of the glue storage barrel 2 and also can prevent the glue storage barrel 2 from rotating in the installation cavity 9.

[0040] In some embodiments, see Figure 4 The glue storage cylinder 2 includes a cylinder 21 for accommodating the glue to be injected, a sliding plate slidably arranged in the cylinder 21, and a glue outlet 22 detachably connected to the glue outlet of the cylinder 21. In fact, the cylindrical cylinder 21 is detachably arranged in the installation cavity 9. Figure 3 A receiving opening 15 is also provided at the end of the glue gun holder 1 relatively far away from the threaded rod 3, and the receiving opening 15 is communicated with the mounting cavity 9, and when the cylinder 21 is located in the mounting cavity 9, the glue outlet of the cylinder 21 is located in the receiving opening 15 and protrudes from the end side wall of the glue gun holder 1, and then the glue nozzle 22 is threadedly connected to the glue outlet.

[0041] In fact, when performing the glue discharging operation, the operator holds the handle 5 to rotate the threaded rod 3, so that the threaded rod 3 moves linearly on the glue gun frame 1, and the end of the threaded rod 3 conflicts with the sliding plate in the barrel 21. As the threaded rod 3 continues to move, the sliding plate squeezes the glue liquid in the barrel 21, and then the glue liquid is discharged from the glue outlet of the barrel 21 and through the glue nozzle 22. When the glue liquid in the current glue storage barrel 2 is completely used up, the operator rotates the threaded rod 3 to disengage the threaded rod 3 from the inside of the barrel 21, and after removing the glue nozzle 22, the operator pushes the glue storage barrel 2 out through the connecting barrel.

[0042] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
