[0002] Common structures of foaming guns include a gun body and a handle that are molded as one piece, a trigger installed on the bottom of the gun body and a connector for the foaming tank formed on the top, and a barrel installed at the front end of the gun body. The defects are that the integrated configuration of the gun body and the grip is complex and difficult to mold. The yield rate is low during the injection molding process, resulting in high costs. In addition, if the gun body or the grip is damaged during subsequent use, it needs to be replaced as a whole, which has high maintenance costs and needs to be improved. Utility Model Content

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] This application document discloses a new foaming gun, including a gun body and a handle. The gun body includes a front part and a rear part, and the rear part is integrally formed with the handle. The front part and the rear part both have cavities. The tail end of the front part and the head end of the rear part are both provided with cavities connected to their cavities. The tail end of the front part is sleeved on the head end of the rear part and a fastener is provided at the sleeve to fix the two together.

[0005] The present invention improves the structure of the foaming gun. Specifically, the gun body is divided into a front part and a rear part. The rear part and the handle are integrally formed. The tail end of the front part is connected with the head end of the rear part and fixed with fasteners. The overall molding structure of the foaming gun is changed to a split assembly structure, which helps to reduce the molding difficulty and reduce the subsequent maintenance costs.

[0006] For fasteners, such as threaded types, such as screws, bolts, or non-threaded cylinders, they can be directly radially embedded after being fitted to fix the two, or glue can be used as fasteners, and the front tail end and the rear head end can be fitted together and fixed with screws, bolts, cylinders, etc., or glued.

[0007] Preferably, the fastener is a threaded type, and the end of the fastener passes through a hole formed on the front peripheral wall and is threadedly connected to the rear head end peripheral wall in the cavity.

[0008] Furthermore, a boss is formed on the rear peripheral wall, and the end face of the front tail end cavity is in contact with the boss. When assembled, the boss is used to limit the front part, thereby improving the stability of the structure and facilitating assembly and molding.

[0009] Furthermore, a notch is formed at the bottom wall of the cavity opening at the tail end of the front part, and a second boss is formed on the lower peripheral wall of the head end of the rear part. The tail end of the front part is sleeved on the head end of the rear part and the notch wall is in contact with the corresponding boss second. Adding the notch helps to expand the cavity opening, making it easier for the front and rear parts to be fitted together. When fitting and assembling, the second boss is used to limit the front part, thereby improving the stability of the structure and facilitating assembly and forming.

[0010] Furthermore, the top surface of the front portion is formed with a connector for docking with the foaming tank, and the specific configuration of the connector can refer to the conventional structure.

[0011] Furthermore, a bolt is threadedly connected to the tail end face of the rear portion and the bolt moves axially, so that the bolt can be screwed in conveniently to limit the position of the trigger on the gun body.

[0012] Furthermore, a cavity is formed in the handle and a mounting port communicating with the cavity is formed at the bottom of the handle, which helps to reduce weight, and a corresponding functional mechanism can also be installed in the internal cavity through the mounting port.

[0013] Furthermore, a convex plate is formed on the front end surface of the handle at least in the middle of the gripping area. When gripping, the convex plate is located between the fingers, and the fingers abut against the convex plate to form support, which helps to improve stability when gripping.

[0014] Furthermore, a non-slip surface is formed on the gripping area of ​​the rear end surface of the handle to improve grip stability.

[0015] Furthermore, it also includes a gun barrel, and the front end of the gun body is connected to the gun barrel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The utility model improves the structure of the foaming gun from the conventional integral configuration to a split assembly type, which helps to reduce the difficulty of molding and improve the yield rate. In addition, the corresponding parts can be replaced according to needs later, reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-4 As shown, the novel foaming gun in this example includes a gun body 1, a handle 2, and a barrel 3. The gun body 1 includes a front portion 10 and a rear portion 11. The front portion 10 and the rear portion 11 are typically cylindrical in shape, with the front end of the front portion 10 connected to the barrel 3. Both the front portion 10 and the rear portion 11 have cavities formed therein for mounting corresponding functional components. For example, the trigger is mounted in the front cavity, while the rear cavity allows for movement of a guide sleeve within the foaming gun.

[0028] The tail end of the front part 10 and the head end of the rear part 11 are both formed with cavities connected to their cavities, wherein a notch 17 is formed at the bottom wall of the tail end cavity of the front part 10, and the tail end of the front part 10 is sleeved on the head end of the rear part 11. The existence of the notch facilitates the expansion of the front tail end cavity and facilitates the insertion of the head end of the rear part 11 into the tail end cavity of the front part 10 to form a nested structure.

[0029] In this example, a fastener (not shown in the figure) is added to the fitting of the tail end of the front part 10 and the head end of the rear part 11 to fix the two together. The fastener is such as a screw, and a through hole 16 is formed on the peripheral wall of the tail end of the front part 10. A corresponding through hole or threaded hole 13 is formed on the peripheral wall of the head end of the rear part 11 corresponding to the through hole 16. After fitting together, the end of the fastener passes through the through hole 16 on the peripheral wall of the tail end of the front part 10 and is threadedly connected to the through hole or threaded hole 13 on the peripheral wall of the head end of the rear part 11 in the cavity. The split structure helps to reduce the difficulty of forming, and if the front part is damaged during subsequent use, the front part can be replaced accordingly, thereby reducing maintenance costs.

[0030] To facilitate assembly, in this example, a boss 15 is formed on the peripheral wall of the rear part 11. The boss can be in the shape of a block or a strip. When assembled, the end face of the cavity at the tail end of the front part 10 abuts against the boss 15, and the boss 15 limits the fitting position of the front part 10. The position of the boss can be preset. For example, when the end face of the cavity at the tail end of the front part 10 abuts against the boss 15 during the fitting process, the through hole at the peripheral wall at the tail end of the front part 10 corresponds to the through hole at the peripheral wall at the head end of the rear part 11, and fasteners can be screwed in to fix it.

[0031] A convex boss 14 can also be formed on the lower peripheral wall of the head end of the rear portion 11, as shown in FIG. Figure 4 As shown, bosses 14 are formed at relative positions at the lower part of the head end of the rear part 11, the tail end of the front part 10 is sleeved on the head end of the rear part 11, and the notch wall abuts against the corresponding boss 14. The position of the boss 14 can also be preset. When the two side walls of the notch 17 abut against the boss 14, the through holes in the peripheral wall of the tail end of the front part 10 correspond to the through holes at the peripheral wall of the head end of the rear part 11, which facilitates the installation of fasteners.

[0032] The bolt 4 can also be installed at the end face of the rear end 11, and the bolt can be turned to move forward or backward axially, and the forward movement into the cavity of the rear portion 11 can limit the movement of the guide sleeve in the cavity, thereby limiting the rotation of the trigger. For the installation of the bolt, a threaded hole can be formed at the end face of the rear end 11, or a nut can be directly fixed.

[0033] The connector for connecting with the external foaming tank in the foaming gun is generally arranged at the head end of the gun body. In this example, the connector 12 is integrally formed at the top surface of the front portion 10 of the gun body 1 .

[0034] In this example, a cavity is also pre-formed in the handle 2, and a mounting port 22 is formed at the bottom end surface of the handle to communicate with the cavity. The cavity is formed to reduce weight or install corresponding functional parts as needed.

[0035] To enhance grip stability, a raised plate 21 may be formed in the center of the gripping area on the front face of the handle 2. The number of raised plates may be single or multiple, and the height of the raised plates may be predetermined. This allows the raised plates to be positioned between the fingers during gripping, providing support and improving grip stability. Furthermore, a non-slip surface 23 may be formed in the gripping area on the rear face of the handle 2, such as a plurality of strip-shaped raised ridges arranged at intervals, or a plurality of raised columns arranged at intervals, to similarly enhance grip stability.

[0036] As for the materials of the gun body and grip, such as plastic, the specific model can be freely selected according to performance requirements.

[0037] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
