Fill in the glue. The inner tube 21 further protrudes from the outer surface of the top core portion 214 with a flange 215 and sleeves a nozzle plug 216 and a bushing 217. The width of the flange 215 in the lateral direction is not less than the inner tube 22 The width of the wall along the lateral direction. The nozzle plug 216 surrounds the outer wall surface of the top core portion 214 and is located on a side of the flange 215 away from the outer tube 22. One end of the bushing 217 is disposed between the flange 215 and the outer tube 22 and the other end extends away from the outer tube 22, and the bushing 217 surrounds the outer side of the nozzle plug 216.

The inlet head 30 is connected to the first end 211 of the inner tube 21, and the inlet head 30 is fixedly connected to the inner tube 21 in a screw-locking manner in the embodiment, and is filled with adhesive between the two. And the intake head 30 is inserted into the first end 221 of the outer tube 22. An intake port 31 is provided in the intake head 30, and the intake passage 31 and the air passage 213 of the inner tube 21 communicate with each other.

The intake head 30 is provided with a one-way valve member 32 in the intake passage 31. The one-way valve member 32 only allows gas to enter the inner tube 21 from the intake passage 31 of the intake head 30 in one direction. Air passage 213. One end of the intake head 30 remote from the communication device 20 is provided with a first threaded portion 33 which is externally threaded in this embodiment. The outer surface of the intake head 30 is further provided with a dial portion 34 which is located between both ends of the intake head 30. The dial portion 34 is embossed in this embodiment.

One end of the air outlet head 40 is connected to the second end 222 of the outer tube 22. The air outlet head 40 is fixedly connected to the second end 222 of the outer tube 22 in a screw-lock manner in the present embodiment. Fill in the glue. One end of the air outlet head 40 away from the communication device 20 is provided with a second threaded portion 41. The second threaded portion 41 is internally threaded in this embodiment, and the second threaded portion 41 and the first threaded portion 33 are in specifications. the same.

When the air pump connector 10 is in use, the air inlet head 30 can be first connected to the air nozzle head of the air pump, and the air outlet head 40 can be connected to the air nozzle of the shock absorber. The air pump connector 10 can be screwed separately. The lock is connected in such a manner that the first threaded portion 33 is connected to the inflator and the second threaded portion 41 is connected to the shock absorber so that the three can be firmly connected. And the air inlet head 30 of the air pump connector 10 is rotatable relative to the outer tube 22 of the communication device 20, and the air outlet head 40 is rotatable relative to the inner tube 21 of the communication device 20, so that the air inlet head 30 and the air outlet head 40 are It does not interfere with each other during connection to the pump and the shock absorber.

When the user operates the pump to pump air, high-pressure gas can enter through the intake head 30, pass through the communication device 20, and output to the shock absorber via the air outlet head 40 to supplement the high-pressure gas in the shock absorber. Further, since the one-way valve member 32 allows only gas to flow in one direction, high-pressure gas recirculation can be avoided. With the air pump connector 10, even if the air nozzle of the shock absorber is located at a position where airing is not easy, the air pump connector 10 can go deep into the dead space and smoothly complete the work.

Referring to Figures 4 and 5, there is shown a perspective exploded view and a cross-sectional structural view of a second embodiment of a pump connector for a shock absorber of the present invention. The second embodiment of the present invention is substantially the same as the first embodiment, and the main difference is that the top core portion 214a is fixedly coupled to the inner tube 21a in an integrally formed manner in this embodiment. The rest of the structure is the same as that of the first embodiment, and will not be described again here.

As far as the above description is concerned, it can be concluded that the present invention has the following advantages:

1. The pump connector for a shock absorber of the present invention, comprising: a communication device, an intake head and an air outlet head, the communication device comprising an inner tube and an outer tube, the inner tube including a first end and a second end different from the first end, the inner tube is provided with an air passage, the air passage communicates with the first end and the second end of the inner tube, and the outer tube can be sleeved outside the inner tube relative to the inner tube The outer tube includes a first end and a second end different from the first end, the first end of the outer tube corresponds to the first end of the inner tube, and the second end of the outer tube and the second end of the inner tube Correspondingly, the second end of the inner tube is provided with a top core portion, and the inner tube is sleeved with a nozzle plug at the top core portion, the air nozzle plug surrounds the outer wall surface of the top core portion, and the air inlet head is connected to the inner tube At the first end, an intake port is arranged in the intake head, and the air passages of the intake passage and the inner tube are in communication with each other, and the intake head is provided with a one-way valve member in the intake passage, and the one-way valve member is only Allowing gas to enter the air duct of the inner tube from the intake port of the intake head in one direction, and a first thread portion is provided at one end of the intake head away from the communication device One end of the air outlet head is connected to the second end of the outer tube, and one end of the air outlet head away from the communication device is provided with a second threaded portion.
