[0002] An adhesive extrusion gun, also known as a glue gun, is used to push the colloid in the glue cartridge out in segments during use. It usually consists of a gun barrel, a push rod, a gun handle, and a grip. When actually applying glue, the glue tube is placed in the gun barrel, and the operator presses the grip to drive the push rod forward, and then slowly pushes the glue in the glue tube out through the push rod.

[0003] The existing Chinese patent with the publication number CN107116010B discloses a glue gun, which includes a main body, a push rod, a push block, a connecting rod group, a trigger, and a limiting member. A grip extends from the bottom end of the main body. The push block and the connecting rod group are located in the main body, the limiting member is located at the rear end of the main body, the push rod passes through the limiting member, the main body, and the push block. The connecting rod group includes two connecting rods arranged horizontally and clamping an angle with each other, one of the connecting rods abuts against the push block, and the trigger is pivotally arranged on the main body and one end thereof abuts against a pushing wheel between the two connecting rods.

[0004] Regarding the above related technologies, it is found that the angle between the gun handle and the grip of the existing glue gun is determined during use, that is, the stroke of the grip rotation during glue application is also determined at the factory. However, due to the differences in the hands and usage habits of the glue applicators, the unified grip angle is not suitable for the comfortable operation of different personnel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] The embodiment of the present application discloses an adhesive extrusion gun with adjustable stroke. Refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, an adhesive extrusion gun with adjustable stroke includes a gun barrel 1 and a push rod 2 slidably installed in the gun barrel 1. One end of the gun barrel 1 is fixedly installed with a gun handle 3, and a grip 4 for adjusting the position of the push rod 2 is rotatably installed on the gun handle 3. The grip 4 includes a handle rod 41 and a dial block 42. The handle rod 41 is rotatably installed on the dial block 42, and a plug row 5 that locks with the dial block 42 is inserted into the handle rod 41. A number of positioning shallow grooves 420 are evenly formed on the outer side surface of the dial block 42 in the circumferential direction, and an elastic frame 6 corresponding to the positioning shallow grooves 420 is also installed on the handle rod 41. By installing the push rod 2 in the gun barrel 1, it is convenient to stably extrude through the push rod 2 after the rubber tube is installed in the gun barrel 1. The gun handle 3 is provided to facilitate stable gripping during caulking. At the same time, by installing the grip 4 on the gun handle 3, when the caulking operator pulls the trigger and rotates the grip 4, the dial on the push rod 2 can be driven, realizing stable feeding of the push rod 2. By designing the traditional integrally formed grip 4 into two parts, namely the handle rod 41 and the dial block 42, the distance between the handle rod 41 and the gun handle 3 can be changed by adjusting the angle of the handle rod 41 on the dial block 42 during use, thereby achieving the purpose of meeting the gripping operations of different users. After adjusting the angle of the handle rod 41 on the dial block 42, the plug row 5 can be inserted and locked to ensure the stability of the overall grip of the grip 4. And through the settings of the positioning shallow grooves 420 and the elastic frame 6, it is ensured that the handle rod 41 is easier to position when rotating and adjusting on the dial block 42, facilitating the plug row 5 to better determine the insertion position for locking.

[0034] Referring to Figure 2 , Figure 3 and Figure 5 As shown in the figure, the handle rod 41 includes a bent rod portion 411 and a concave clamping plate 412. The concave clamping plate 412 is arranged at the head of the bent rod portion 411, and the concave clamping plate 412 is integrally formed with the bent rod portion 411. By setting the structure of the handle rod 41, the concave clamping plate 412 is installed at the head of the bent rod portion 411 to ensure that the concave clamping plate 412 can be clamped on the dial block 42 during use. Both the concave clamping plate 412 and the dial block 42 are rotatably installed in the gun handle 3. In this way, when the concave clamping plate 412 and the dial block 42 are not locked with each other, they can rotate independently, and when they are locked with each other, they can rotate synchronously. An arc-shaped groove 413 is formed on the side surface of the concave clamping plate 412, and a number of insertion holes 414 for installing the plug row 5 are arranged in the arc-shaped groove 413. By forming the arc-shaped groove 413 on the side surface of the concave clamping plate 412, it is convenient for the plug row 5 to be positioned and installed. At the same time, through the setting of the insertion holes 414, it is ensured that the plug row 5 is locked for use after being inserted.

[0035] Referring to Figure 2 , Figure 3 and Figure 5As shown, the shifting block 42 includes a cylindrical block 421 and an outer shifting rod 422. The outer shifting rod 422 is arranged at the outer end of the cylindrical block 421 and is fixedly connected to the cylindrical block. By setting the structure of the shifting block 42, it is ensured that the outer shifting rod 422 is fixedly installed on the cylindrical block 421, so that the paddle on the push rod 2 can be shifted by the outer shifting rod 422 during glue application. Corresponding mating holes 423 corresponding to the jacks 414 are evenly formed in the circumferential direction on the cylindrical block 421, and the mating holes 423 penetrate through both sides of the cylindrical block 421. By forming the mating holes 423 in the cylindrical block 421, it is convenient to insert and lock through the patch cord 5 after the mating holes 423 are aligned with the jacks 414.

[0036] Referring to Figure 5 As shown, the patch cord 5 includes an arc-shaped outer plate 51 and a plurality of plug rods 52. The plug rods 52 are evenly arranged on one side of the arc-shaped outer plate 51 and are fixedly connected to the arc-shaped outer plate 51. By setting the structure of the patch cord 5, it is ensured that a plurality of plug rods 52 are fixedly installed on the arc-shaped outer plate 51, so that the plug rods 52 can be inserted into the mating holes 423 and the jacks 414 when locking is required, and the arc-shaped outer plate 51 can be received in the arc-shaped groove 413.

[0037] Referring to Figure 4 As shown, the elastic frame 6 includes a mounting base 61 and a movable frame 62. The mounting base 61 is fixedly installed on the concave clamping plate 412, the movable frame 62 is slidably installed on the mounting base 61, and a tension spring 63 is also installed between the movable frame 62 and the mounting base 61. By setting the structure of the elastic frame 6, it is ensured that the movable frame 62 is installed through the mounting base 61, the movable frame 62 is arranged along the radial direction of the cylindrical block 421, and under the action of the tension spring 63, the lower end of the movable frame 62 can be stably clamped into the positioning shallow groove 420. When the handle 41 rotates relative to the shifting block 42, the movable frame 62 can jump between the positioning shallow grooves 420 to achieve better positioning and use.

[0038] Referring to Figure 4 As shown, the movable frame 62 includes a cylindrical rod 621, a sliding rod 622 and a top plate 623. The sliding rods 622 are fixedly installed at both ends of the cylindrical rod 621, and the top plate 623 is fixedly installed at the head of the sliding rod 622. By setting the structure of the movable frame 62, it is ensured that the cylindrical rod 621 can be slidably installed on the mounting base 61 through the sliding rods 622 at both ends, and the sliding rods 622 at both ends can be connected by the top plate 623, and the tension spring 63 is connected through the top plate 623. In this way, the movable frame 62 can be driven to move downward by the tension spring 63. When not stressed, the cylindrical rod 621 can be inserted into the positioning shallow groove 420, and when stressed, the cylindrical rod 621 can slide out of the positioning shallow groove 420.

[0039] The implementation principle of an adjustable-stroke adhesive extrusion gun in an embodiment of this application is as follows: When in need of use, the caulking operator can first adjust the distance between the handle rod 41 of the handle 4 and the gun handle 3, so as to enable the caulking operator to hold it better with the hand. When adjustment is required, first pull out the socket 5 from the handle rod 41, then rotate the handle rod 41 at the angle of the shifting block 42. After rotating and adjusting the angle, insert the socket 5 into the jack 414 and the mating hole 423 again. In this way, the operator can easily perform the caulking operation.

[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
