Tire repair liquid aerosol spraying cover assembly and aerosol bottle

Abstract

The utility model relates to the technical field of tire repairing aerial fog spraying, and particularly discloses a tire repairing liquid aerial fog spraying cover assembly and an aerial fog bottle applying the aerial fog spraying cover assembly, which comprise a cover body, a nozzle arranged on the cover body, a conveying pipe arranged on the nozzle in an interference fit mode, a connector arranged at the other end of the conveying pipe and used for being connected with an air tap on a tire, and a clamping groove arranged on the nozzle. A clamping groove is formed in the outer side of the nozzle, an anti-disengaging block is arranged on the inner wall of the conveying pipe and corresponds to the clamping groove, and the anti-disengaging block and the clamping groove are matched in a clamped mode. Even if air pressure in the tire flows back into the conveying pipe to generate reverse thrust on the nozzle, the nozzle and the conveying pipe cannot fall off due to clamping fit of the anti-falling block and the clamping groove, and therefore it is guaranteed that tire repairing liquid can be normally infused into the tire.

[0002] The tire sealing glue spraying device on the market mainly consists of a spray cap body with a bottle body arranged at the bottle mouth, a nozzle is connected to the spray cap body, one end of the nozzle is connected to a delivery pipe, and the other end of the delivery pipe is connected to an air nozzle connector for connecting with the air nozzle on the tire. When in use, by pressing the push button on the spray cap, the tire sealing glue stored in the bottle can be delivered to the tire to complete the automatic sealing of the tire;

[0003] However, in actual situations, even if the tire is punctured and leaking, the air pressure in the tire is not completely leaked out, and there is still a certain pressure in the tire. Therefore, when the air nozzle connector on the delivery tube is connected to the air nozzle on the tire, the gas in the tire will flow back into the delivery tube through the air nozzle. At this time, due to the reverse thrust of the gas flowing back from the tire, it is easy for the nozzle and the delivery tube to fall off, making it impossible to normally inject the tire repair fluid into the tire.

[0004] The technical problem to be solved by the present application is to design a tire repair liquid aerosol spray cap assembly that can ensure the connection stability between the nozzle and the delivery pipe to avoid falling off due to the reverse push of the gas, and an aerosol bottle using the aerosol spray cap assembly.

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] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a tire repair liquid aerosol spray cover assembly, including a cover body 1, a pressing slide groove 10 is provided on the cover body 1, a pressing buckle 5 that is limited and slidably matched with the pressing slide groove 10 is provided in the pressing slide groove 10, a nozzle 2 is provided on the pressing buckle 5, the nozzle 2 is communicated with the inside of the pressing buckle 5, a spray pipe 51 is also provided inside the pressing buckle 5, the nozzle 2 is communicated with the spray pipe 51, pressing the pressing buckle 5 can spray the solution in the bottle from the nozzle 2 through the aerosol valve, a delivery pipe 3 with an interference fit is provided on the nozzle 2, and the other end of the delivery pipe 3 is provided with a connector 4 for connecting to the air nozzle on the tire, a card slot 20 is provided on the outer side of the nozzle 2, and an anti-slip block 30 is provided on the inner wall of the delivery pipe 3 corresponding to the card slot 20, and the anti-slip block 30 is engaged with the card slot 20, which In this way, when the connector 4 is connected to the air nozzle on the tire, part of the air pressure in the tire will flow back into the delivery pipe 3 through the connector 4. Since a one-way valve is provided in the nozzle 2 and the nozzle 2 is tapered, the air pressure entering the delivery pipe 3 will generate a reverse thrust with the nozzle 2, which may easily cause the nozzle 2 and the delivery pipe 3 to fall off due to the reverse thrust, so that the tire repair fluid cannot be normally injected into the tire during the tire repair process. However, by making the anti-falling block 30 and the card slot 20 engage with each other, even if the air pressure in the delivery pipe 3 generates a reverse thrust on the delivery pipe 3 due to the nozzle 2, the anti-falling block 30 and the card slot 20 engage with each other, so that the nozzle 2 and the delivery pipe 3 will not fall off due to the engagement between the anti-falling block 30 and the card slot 20, thereby ensuring the connection stability between the nozzle 2 and the delivery pipe 3.

[0025] In order to further ensure the stability of the connection between the delivery pipe 3 and the nozzle 2, after the delivery pipe 3 is connected with the sleeve 31 by interference fit, another sleeve 31 is sleeved on the end where the delivery pipe 3 is connected to the nozzle 2, and the sleeve 31 also has an interference fit with the outer side of the delivery pipe 3. By adding an interference fit sleeve 31 at the end where the delivery pipe 3 is connected to the nozzle 2, the locking force of the anti-slip block 30 and the slot 20 can be enhanced, thereby further ensuring the connection stability between the delivery pipe 3 and the nozzle 2.

[0026] A limiting groove 11 is also provided at the rear end of the pressing slide 10, and the limiting groove 11 is U-shaped. When the pressing buckle 5 is installed in the pressing slide 10, the shaft sleeve 31 is located in the limiting groove 11, and the inner walls on both sides of the pressing slide 10 are provided with limiting baffles 12 arranged in a mirror image. The limiting baffles 12 abut against the rear side of the pressing buckle 5, so that the pressing buckle 5 can be limited, and the pressing buckle 5 can be limited and slidably matched in the pressing slide 10. The front side of the pressing slide 10 is arc-shaped, and a locking groove 13 is provided on the front side of the pressing slide 10, and a limiting block 14 is provided at the upper end of the locking groove 13. The front side of the pressing buckle 5 corresponds to the locking groove 13 A clamping strip 50 is provided. When the push buckle 5 is installed in the push slide groove 10, the clamping strip 50 and the clamping groove 13 are limited and slidably matched, and the upper end of the clamping strip 50 abuts against the limiting block 14 when the push buckle 5 is in a stationary state in the push slide groove 10. In this way, when the push buckle 5 is pressed downward, the sleeve 31 will abut against the bottom of the limiting groove 11, and when the push buckle 5 is reset upward, the upper end of the clamping strip 50 will abut against the limiting block 14, thereby limiting the downward pressing amplitude of the push buckle 5. By providing a limiting block 14 to abut against the upper end of the clamping strip 50, the push buckle 5 can also be prevented from falling off from the push slide groove 10.

[0027] Embodiment 2: An aerosol bottle, which is provided with any tire repair liquid aerosol spray cap assembly of the above-mentioned embodiment 1.

[0028] The working principle or beneficial effect of the utility model is as follows: a groove 20 is provided on the outer side of the nozzle 2, an anti-slipping block 30 is provided on the inner wall of the delivery tube 3 corresponding to the groove 20, and the anti-slipping block 30 and the groove 20 are engaged with each other, so that when the connector 4 is connected to the air nozzle on the tire, even if the air pressure in the tire flows back into the delivery tube 3 to generate a reverse thrust on the nozzle 2, the anti-slipping block 30 and the groove 20 are engaged with each other, so that the nozzle 2 and the delivery tube 3 will not fall off, thereby ensuring that the tire repair fluid can be normally injected into the tire.

[0029] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
