Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1, the detachable air charging device in this embodiment is used for charging a ball, and comprises a communicating member 2 for supplying air supplied by a cylinder body 1 to an air charging head 3, wherein a first end of an inner cavity of the air charging head 3 is movably inserted into the communicating member 2, a second end of the air charging head 3 is inserted into an air charging needle 31, the communicating member 2 is provided with a first sealing structure 22, and the first sealing structure 22 is used for sealing a second end of the inner cavity of the air charging head 3 when a socket nozzle 34 of the air charging needle 31 is movably inserted into the communicating member 2 relative to the communicating member 2.
The cylinder block 1 is provided with a second sealing structure 11 for sealing the junction of the cylinder block 1 and the communication 2.
The outside of the communicating piece 2 is provided with a thread 21, and the inside of the inflating head 3 is provided with an internal thread 32 matched with the thread 21. The inner side wall of the air charging head 3 is gradually reduced from the arrangement position of the internal thread 32 to the other end part to form a gradual change part for clamping the first sealing structure 22 and the second sealing structure 11.
The first end of the air charging head 3 is provided with a blocking sealing structure 33 for pressing the second sealing structure 11 by the air charging head 3 moving close to the cylinder body 1. When the inflation head 33 is screwed with the communication piece 2, the internal thread 32 is matched with the thread 21, so that the gradual change part can gradually compress the first sealing structure 22, the blocking sealing structure 33 on the outer side of the inflation head 33 can gradually compress the second sealing structure 11, and the tightness of the first sealing structure 22 and the second sealing structure 11 can be further improved. The first seal structure 22 and the second seal structure 11 are both elastic seal structures.
The second end of the air charging head 3 is provided with a through hole, and the inner side of the through hole is provided with a third sealing structure 35 for sealing the communication part of the air charging needle 31 and the sleeving mouth 34. The through hole is provided at one end of the gradation portion near the inflating needle 31. The inflating needle 31 is arranged at the center of the sleeving mouth 34, the cross section of the other end of the sleeving mouth 34 is provided with a vent hole with the same size as the opening of the inflating needle 31, and the cross section is airtight except the vent hole. The cross section of the inflation needle 31 is smaller than that of the through hole so that the inflation needle 31 can be inserted into the through hole.
The third sealing structure 35 is fixedly connected to the through hole. One end of the third sealing structure 35 is provided with a sealing plug 36 for sealing the third sealing structure 35. The socket 34 may be fixedly connected to the through hole, or may be hinged to the through hole by a screw. The inflating needle 31 is fixedly connected to the sleeve joint mouth 34, so that the inflating head 3 can be detached from the communicating piece 2 when the detachable inflating device is not used, and then the sleeve joint mouth 34 and the inflating needle 31 can be detached from the inflating head 3, so that the inflating head 3, the communicating piece 2 and the inflating needle 31 can be cleaned conveniently, and the detachable inflating device can be detached practically and conveniently next time.
The communicating element 2 comprises a limiting part 23 for limiting the socket joint mouth 34 to be inserted into the communicating element 2, and the first sealing structure 22 is arranged on the limiting part 23. The communicating element 2 is a cylindrical body with two open ends, and the open section of one end of the limiting part 23 is set to be the same as the open section of the communicating element 2.
The communicating member 2 is provided with a socket 24 sleeved on the outer surface of the socket 34. When the inflation head 3 is in threaded connection with the communicating piece 2, the internal threads 32 are matched with the threads 21, the sleeve joint mouth 34 stretches into the sleeve joint mouth 24 until reaching the limit part 23 of the communicating piece 2 to stop, and the sleeve joint mouth 34 is matched with the structure of the sleeve joint mouth 24, so that gas leakage can be further reduced, and the tightness is improved. The socket 24 is provided at the center of the stopper 23. The opening section of the other end of the limiting portion 23 is set smaller than the opening section of the spigot 34 so as to block the spigot 34 from continuing to move toward the communication member 2. The mouth opening section of spigot 34 is smaller than the mouth opening section of spigot 24 so that spigot 34 can move within the interior cavity of spigot 24.
When inflation is required, the inflation needle 31 is inserted into the through hole of the inflation head 3 until the sleeve joint mouth 34 abuts against the third sealing structure 35. Then the inflating head 3 is connected with the communicating piece 2 in a screwed mode until the sleeving mouth 34 is abutted against the limiting part 23, the gradual change part of the inner cavity of the inflating head 3 can compress the first sealing structure 22 at the moment, the sealing performance of the first sealing structure 22 is improved, the blocking sealing structure 33 outside the inflating head 3 can compress the second sealing structure, the sealing performance of the second sealing structure is improved, the sleeving mouth 34 is matched with the structure of the sleeving mouth 24, the sealing performance can be further improved, and therefore the overall sealing performance of the detachable inflating device is improved.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
