Description

Technical Field

[0001] This utility model relates to a glue gun. Background Technology

[0002] A glue gun is a tool for applying adhesive, widely used in industries such as construction and decoration, electronics, automobiles and auto parts, and shipbuilding and container manufacturing. The operator applies the adhesive by pressing a plate with their hand. In existing glue guns, the gun body has a space for storing the adhesive (generally for hard adhesives such as rigid silicone sealant or sealant), and there are notches along the axial direction of the gun body for easy disassembly and installation of the adhesive (usually on the upper surface of the gun body). For example, Chinese utility model patent CN216441014U discloses an adjustable stroke glue gun. In practical use, it is found that when more than half of the glue in the caulking gun is used (approaching the outlet), the push rod causes the rear end of the glue to be slightly tilted towards the notch. At this point, the center line of the glue and the center line of the push rod are not on the same straight line. This makes it more difficult to squeeze out the remaining glue. It is time-consuming and laborious to use all the remaining glue, resulting in low caulking efficiency. Discarding the remaining glue would be a great waste. Therefore, it is necessary to improve the existing technology to address this problem. Utility Model Content

[0003] (a) Technical problems that need to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a glue gun designed to prevent glue from curling up in the later stages of glue application and to easily squeeze out the remaining glue for use. This not only improves glue application efficiency but also reduces waste and better meets user needs.

[0005] (ii) Technical solutions to be adopted

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A glue-applying gun includes a gun body for storing glue and a handle disposed at the rear end of the gun body. A glue-pressing trigger is movably mounted on the handle via a fulcrum shaft. A push rod controlled by the glue-pressing trigger is disposed on the handle. The push rod moves along the axial direction of the gun body. A notch for disassembling and installing glue is provided on the gun body. The notch is arranged along the axial direction of the gun body. A positioning element is provided on the handle to prevent the rear part of the glue stored in the gun body from tilting up during the process of being pushed by the push rod.

[0008] Preferably, the positioning element includes a mounting seat disposed on the gun handle, the mounting seat having a positioning seat, the front portion of the positioning seat extending to the notch position on the gun body.

[0009] Preferably, the mounting base is provided with a rotating hole and a sliding hole, the sliding hole is provided with a locking position and an opening, the rotating hole is provided with a rotating shaft, the two ends of the rotating shaft are located on the positioning seat, and the positioning seat is provided with a sliding shaft.

[0010] Preferably, the gun handle and the mounting base are integrally formed.

[0011] Preferably, the rotating hole is a strip-shaped hole.

[0012] (III) The technical effects to be achieved

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Firstly, the gun handle of this utility model is provided with a positioning component to prevent the rear of the adhesive material stored in the gun body from tilting up during the pushing process by the push rod. This positioning component helps to prevent the adhesive material from tilting up in the later stages of use, so that the remaining adhesive material can be easily squeezed out for use. This not only improves the efficiency of dispensing but also reduces waste and better meets the needs of use.

[0015] Secondly, the positioning component of this utility model includes a mounting seat set on the gun handle, and a positioning seat is provided on the mounting seat. The front part of the positioning seat extends to the notch position of the gun body. This setting is reasonable and the structure is extremely simple, which facilitates production and reduces the input of production and manufacturing costs.

[0016] Thirdly, the mounting base of this utility model is provided with a rotating hole and a sliding hole. The sliding hole is provided with a locking position and an opening. A rotating shaft is provided in the rotating hole, and both ends of the rotating shaft are located on the positioning seat. The positioning seat is provided with a sliding shaft. In use, when the positioning seat rotates towards one side of the gun body with the rotating shaft as the pivot point, the sliding shaft enters through the opening, moving the positioning seat forward slightly. This facilitates the sliding shaft to enter the locking position along the sliding hole. At this time, the positioning seat will be fixed on the mounting base. By pulling the pressure trigger, the pressure trigger will cause the push rod to move forward, thereby squeezing the rubber material stored in the gun body. When the rubber material is squeezed to more than half its content, the subsequent... When in use, the rear of the adhesive material will tilt upwards towards the notch. At this point, the positioning seat will press down on the adhesive material, ensuring that the material remains aligned with the push rod. This allows the push rod to easily squeeze out any remaining adhesive material, significantly improving work efficiency and reducing waste, thus better meeting user needs. When not in use, simply move the positioning seat backwards. This will cause the sliding shaft to retract from its locking position and move along the sliding hole to the opening position. Rotating the positioning seat around the rotation axis away from the gun body facilitates storing or removing adhesive material through the notch. The operation is extremely simple, making it easy to promote and apply on a large scale. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0027] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A glue-applying gun includes a gun body 1 for storing glue and a handle 2 located at the rear end of the gun body 1. A pressure trigger 4 is movably mounted on the handle 2 via a pivot shaft 3. A push rod 5, controlled by the pressure trigger 4, is also located on the handle 2. The push rod 5 moves axially along the gun body 1, thereby squeezing out the glue stored in the gun body 1. A notch 11 for removing and installing the glue is provided on the gun body 1, and the notch 11 is arranged axially along the gun body 1. A positioning feature is provided on the handle 2 to prevent the rear of the glue stored in the gun body 1 from lifting up during the pushing process by the push rod 5. In use, by operating the pressure trigger 4, the push rod 5 moves forward, squeezing the adhesive stored in the gun body 1. When more than half of the adhesive is squeezed out, the rear of the adhesive will tilt towards the notch 11 as it is used further. At this point, the positioning part 6 will press down on the adhesive, ensuring that the adhesive remains aligned with the push rod 5. This allows the push rod 5 to easily squeeze out the remaining adhesive, improving work efficiency, reducing waste, and better meeting user needs. Since the push rod 5 and pressure trigger 4 on the gun handle 2 are common structures in caulking guns, they are not described in detail. For example, related structures are disclosed in patent publications CN 210614236U, CN 212664078 U, and CN 216441014 U.

[0028] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning component 6 includes a mounting seat 61 disposed on the gun handle 2, and a positioning seat 62 disposed on the mounting seat 61. The front part of the positioning seat 62 extends to the notch 11 of the gun body 1, which is beneficial to prevent the rubber material stored in the gun body 1 from lifting up. To further explain, the mounting base 61 is provided with a rotating hole 611 and a sliding hole 612. The sliding hole 612 is provided with a locking position 613 and an opening 614. A rotating shaft 63 is provided in the rotating hole 611, with both ends of the rotating shaft 63 located on the positioning base 62. This arrangement is conducive to the positioning base 62 rotating back and forth around the rotating shaft 63 as the pivot point. It can rotate forward when in use and rotate backward when not in use. The positioning base 62 is provided with a sliding shaft 64. The sliding shaft 64 enters from the opening 614 and continues to move along the sliding hole 612 into the locking position 613. At this time, it is conducive to fixing the sliding shaft 64 in the locking position 613. This can fix the positioning base 62 on the mounting base 61, which helps to prevent the adhesive stored in the gun body 1 from lifting up during use. When the sliding shaft 64 exits from the locking position 613, then moves along the sliding hole 612 and exits from the opening 614, the positioning base 62 can be rotated backward around the rotating shaft 63 as the pivot point. Finally, it should be noted that the rotating hole 611 is a strip-shaped hole, which is beneficial for the positioning seat 62 to rotate to the required position and achieve horizontal movement. In this embodiment, the strip-shaped hole is in the shape of a sports field (rectangular in the middle and arc-shaped at both ends), which is more conducive to implementation.

[0029] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the grip 2 and the mounting base 61 are integrally formed, which helps to strengthen the structural rigidity of the grip 2.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in use, when the positioning seat 62 rotates towards the gun body 1 around the rotating shaft 63, the sliding shaft 64 enters through the opening 614, moving the positioning seat 62 forward slightly. This facilitates the sliding shaft 64 entering the locking position 613 along the sliding hole 612, at which point the positioning seat 62 is fixed on the mounting base 61. By actuating the pressure trigger 4, the push rod 5 moves forward, thus squeezing the adhesive material stored in the gun body 1. When the adhesive material is squeezed to more than half its original content, the rear part of the adhesive material will tilt towards the notch 11 as it is used later. At this time, the positioning seat 62 will press the adhesive material down. This ensures that the adhesive material remains aligned with the push rod 5, allowing the push rod 5 to easily expel any remaining adhesive material. This significantly improves work efficiency, reduces waste, and better meets user needs. When not in use, simply move the positioning seat 62 backward, causing the sliding shaft 64 to retract from the locking position 613 and move along the sliding hole 612 to the opening 614. Rotate the positioning seat 62 around the rotating shaft 63 to the side away from the gun body 1. This facilitates storing or removing adhesive material through the notch 11, making the operation extremely simple and suitable for widespread promotion and application.

[0031] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0032] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
