DETAILED DESCRIPTION

[0023] 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 in 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.

[0024] See also Figure 1-4 The utility model provides an embodiment: a PVC sealant coating gun nozzle, comprising a fixed guide seat 6 for support, a sealing gasket 1 for docking is fixedly arranged on the rear end surface of the fixed guide seat 6,

[0025] A spherical sealing groove 2 is provided on the inner end surface of the fixed guide seat 6, and a material guide groove 5 is provided on the inner end surface of the fixed guide seat 6 and extends to the outside of the sealing gasket 1;

[0026] The sealing device 3 is sealingly rotatably clamped on the inner end surface of the fixed guide seat 6;

[0027] The spraying device 4 is threadedly connected to the outer end surface of the sealing device 3 .

[0028] The sealing device 3 comprises a connecting sphere 31 , a positioning seat 32 is fixedly arranged at the center of the front end surface of the connecting sphere 31 , and a thread groove 33 is provided on the inner end surface of the positioning seat 32 .

[0029] The spraying device 4 comprises a threaded joint 41 , a sealing clamp ring 42 is fixedly provided at the center of the side end surface of the threaded joint 41 , and a spraying pipe 43 is fixedly installed at the center of the side end surface of the sealing clamp ring 42 .

[0030] A guide groove is provided at the center of the rear end surface of the connecting sphere 31 , and the diameter of the guide groove is larger than the diameter of the material guide groove 5 , which can facilitate the subsequent adjustment of the angle of the spraying device 4 to ensure the conduction and liquid supply between the guide groove and the material guide groove 5 .

[0031] The connecting ball 31 is sealed and rotated to be clamped on the inner end face of the fixed guide seat 6 through the spherical sealing groove 2, and the sealing clamp ring 42 is adapted to the threaded groove 33 through the threaded joint 41 and is sealed and threadedly connected to the outer end face of the positioning rotating seat 32. The threaded connection between the threaded joint 41 and the threaded groove 33 can facilitate subsequent users to quickly and conveniently assemble and disassemble spray devices 4 with different structures.

[0032] The working principle of this embodiment is as follows: when in use, the user can fix the device on an external spray gun through the sealing gasket 1. When in use, if it is necessary to apply glue to the required seal, the user can first adjust the angle of the glue application, and can adjust the connecting ball 31 to any angle inside the spherical sealing groove 2. Due to the strong damping setting of the connecting ball 31 and the spherical sealing groove 2, the support stability of the connecting ball 31 after adjustment can be guaranteed. Then the colloid is introduced into the inside of the connecting ball 31 through the spherical sealing groove 2, and finally exported from the spray pipe 43 for coating.

[0033] like Figure 5 As shown, it is the second embodiment of the utility model, which is different from the first embodiment in that a corrugated spray tube 44 is fixedly provided at the center of the side end surface of the sealing clamp 42, and six groups of shaping steel wires 45 are equidistantly provided on the inner end surface of the corrugated spray tube 44.

[0034] The working principle of this embodiment is: when coating some relatively narrow and irregular areas, the user can bend the corrugated spray tube 44 through the six groups of shaping wires 45 inside. The six groups of shaping wires 45 can maintain the spraying shape of the corrugated spray tube 44, thereby facilitating the spraying of different types of spraying areas.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
