Description

Technical Field

[0001] The utility model relates to the technical field of foam glue spraying components, in particular to a polyurethane foam glue spraying component. Background Art

[0002] Foam glue is a kind of glue with foaming and bonding properties. It is mainly used for filling, sealing and bonding the edge seams of building doors and windows, expansion joints of components and holes. In construction, polyurethane foam glue is usually used to seal tiny gaps and holes. The foam glue can must be used with a foam glue spray gun.

[0003] The foaming tube of the existing foam glue spray gun is usually of fixed length and is relatively short. When applying glue at a higher position, construction workers are often required to climb up with the help of a ladder, which is prone to danger. During the process, they may need to climb the ladder repeatedly to apply glue, which reduces construction efficiency.

[0004] Therefore, those skilled in the art provide a polyurethane foam glue spraying assembly to solve the problems raised in the above background technology. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please refer to the attached Figure 1-5 The polyurethane foam glue spraying assembly in the embodiment of the utility model comprises a foaming tank 1, and the top of the foaming tank 1 can be assembled and connected with a glue spraying assembly 3, which can be assembled and connected or detached. The glue spraying assembly 3 and the foaming tank 1 are assembled and disassembled through threads, which is convenient for cleaning or replacement and easy to use;

[0028] The glue spraying assembly 3 includes a first glue spraying tube 31. When the glue spraying assembly 3 is in a fully expanded state, one end of the first glue spraying tube 31 is connected to the second glue spraying tube 32, and one end of the second glue spraying tube 32 is connected to the third glue spraying tube 33. The diameters of the first glue spraying tube 31, the second glue spraying tube 32 and the third glue spraying tube 33 gradually decrease in sequence. On the one hand, when the foam glue is easier to enter the glue spraying assembly 3, and under the gradually decreasing tubes, its spraying pressure is gradually increased, and its range can be improved;

[0029] When the glue spraying assembly 3 is in the folded state, the first glue spraying tube 31, the second glue spraying tube 32 and the third glue spraying tube 33 are connected in sequence. When the first glue spraying tube 31, the second glue spraying tube 32 and the third glue spraying tube 33 are connected in sequence, it is convenient to fill the foam glue at a close distance, and the foam glue is directly sprayed out through the third glue spraying tube 33;

[0030] A glue spraying port 332 is formed at one end of the third glue spraying tube 33 , and the third glue spraying tube 33 is bent near the glue spraying port 332 , so that the foaming tank 1 does not need to be tilted too much when spraying glue, and the tilt of the foaming tank 1 can be reduced, which is convenient to use.

[0031] A trigger plate 2 is connected to the lower part of the first glue spraying pipe 31. When the trigger plate 2 is pressed, the foam glue in the foaming tank 1 is sprayed out through the glue spraying assembly 3. A connecting pipe 12 is connected between the trigger plate 2 and the foaming tank 1. A regulating valve 4 is fixed to one side of the connecting pipe 12. The regulating valve 4 is used to adjust the amount and pressure of the foam glue sprayed.

[0032] A threaded sleeve 11 is fixed to the bottom of the connecting pipe 12 and a thread is fixed to the top of the foaming tank 1. The foaming tank 1 is connected to the threaded sleeve 11 through the thread, so that the connecting pipe 12 can be disassembled, cleaned or replaced, and the installation and disassembly are convenient.

[0033] Both ends of the first glue spraying hose 31 are fixed with a first internal thread 311, and one end of the second glue spraying hose 32 is fixed with a first external thread ring 321. The first external thread ring 321 cooperates with the first internal thread 311. When the glue spraying assembly 3 is in a fully unfolded state, the first external thread ring 321 is threadedly connected to the first internal thread 311 above the first glue spraying hose 31. When the glue spraying assembly 3 is in a folded state, the first external thread ring 321 is threadedly connected to the first internal thread 311 below the first glue spraying hose 31.

[0034] The second glue spraying hose 32 is fixed with a second internal thread 322 at both ends of the inner side, and the third glue spraying hose 33 is fixed with a second external thread ring 331 at one end. The second internal thread 322 cooperates with the second external thread ring 331. When the glue spraying assembly 3 is in a fully unfolded state, the second external thread ring 331 of the third glue spraying hose 33 is threadedly connected with the second internal thread 322 at the upper part of the second glue spraying hose 32. When the glue spraying assembly 3 is in a folded state, the second external thread ring 331 is threadedly connected with the second internal thread 322 at the lower part of the second glue spraying hose 32. Therefore, each part of the glue spraying assembly 3 can be disassembled and separated for easy cleaning and replacement. If one of the glue spraying hoses is damaged, there is no need to replace the entire glue spraying assembly 3, thereby reducing its use cost.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
