[0002] The shock absorber is one of the key parts of a car. It uses the characteristics of gas compression and expansion to reduce mechanical vibration and impact. Therefore, the process of filling the shock absorber with nitrogen is essential.

[0003] The shock absorber consists of components such as oil seals, connecting rods, and guides. The oil seals are used to prevent oil and air pressure loss, and to prevent contaminants from entering the shock absorber. The connecting rod drives the piston to perform reciprocating linear motion in the cylinder under the guidance of the guide. During use, the shock absorber is subjected to the impact force when cushioning the car, and the internal air pressure of the shock absorber decreases, affecting the shock absorber's vibration reduction performance.

[0004] Currently, the inflation process of the shock absorber is to use the factory's inflator to insert a needle tool into the shock absorber's oil seal to inflate the piston cylinder after the shock absorber is assembled, thereby completing the inflation process. This inflation method is not convenient enough and has low inflation efficiency, and cannot meet the needs of shock absorbers in after-sales maintenance and other fields.

[0005] Therefore, there is an urgent need for an inflation device that can solve the above problems and thus improve the convenience of inflation of the shock absorber. Utility Model Content

[0036] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0037] Embodiment:

[0038] A portable inflation device for a shock absorber, referring to Figure 1 , the inflation device includes a connected inflation tooling 1, an air pipe 2, a pressure reducing valve 3, and a nitrogen cylinder 4. When the switch of the nitrogen cylinder 4 is opened, nitrogen enters the inflation tooling 1 along the pressure reducing valve 3 and the air pipe 2.

[0039] Referring to Figure 1 and Figure 2, the inflation tooling 1 includes an inflation component 5 and a joint component 6 that is internally connected to the inflation component 5. One end of the joint component 6 away from the inflation component 5 is connected to the air pipe 2.

[0040] Reference Figure 1 and Figure 2 , the inflation component 5 includes a detachable inflation head 7 and an inflation head seat 8. One end of the inflation head seat 8 is connected to the joint component 6. Nitrogen enters the joint component 6 from the air pipe 2 and enters the inflation head seat 8 and the inflation head 7 along the joint component 6. As Figure 5 shown, one end of the inflation head 7 away from the inflation head seat 8 penetrates into the oil seal 9, thereby enabling nitrogen to smoothly enter the shock absorber. After inflation is completed, a wear-resistant protective sleeve 21 is sleeved on the inflation head 7. The wear-resistant protective sleeve 21 is made of nylon material, and the good wear-resistant characteristics of nylon are used to protect the inflation head 7 to avoid damage to the inflation head 7 affecting the inflation process of the shock absorber.

[0041] Reference Figure 1 and Figure 2 , the inflation component 5 further includes an inflation head handle 11. The inflation head handle 11 is detachably connected to one end of the inflation head seat 8 away from the inflation head 7. The inflation head handle 11 is threadedly connected to the inflation head seat 8, which facilitates the disassembly and assembly of the entire inflation component 5 and makes the entire inflation device more portable. As Figure 5 shown, the inner diameter of the inflation head handle 11 is greater than the outer diameter of the connecting rod 10, and the inflation head handle 11 is sleeved on the connecting rod 10.

[0042] Reference Figure 2 and Figure 5 , a first seal 18 for sealing the gap between the inflation component 5 and the connecting rod 10 is provided between the inflation component 5 and the connecting rod 10. The first seal 18 is located between the inflation head handle 11, the inflation head seat 8 and the connecting rod 10. The first seal 18 is an O-ring. The resilience generated by the extrusion deformation of the first seal 18 is used to seal the inflation component 5 and the connecting rod 10. A second seal 19 is provided between the inflation head seat 8 and the inflation head 7. The second seal 19 is an O-ring. The resilience generated by the extrusion deformation of the second seal 19 is used to seal the inflation head seat 8 and the inflation head 7.

[0043] Reference Figure 2 , the joint component 6 includes a connecting head 12, a quick air joint 13 and an air pipe joint 14 that are connected in sequence. A third seal 20 is provided between the inflation component 5 and the joint component 6. The third seal 20 is a flat gasket seal, that is, the third seal 20 is arranged between the inflation head seat 8 and the quick air joint 13. The connecting head 12 is threadedly connected to the quick air joint 13.

[0044] Reference Figure 3 and Figure 4, one end of the quick air joint 13 close to the inflating head seat 8 is recessed to form a placement groove 15 for accommodating the connecting head 12. The setting of the placement groove 15 increases the contact area between the quick air joint 13 and the connecting head 12. The inner wall of the placement groove 15 is closely attached to the connecting head 12, preventing nitrogen from leaking outside the connection between the connecting head 12 and the quick air joint 13.

[0045] Reference Figure 3 and Figure 4 , the connecting head 12 is threadedly connected to the inflating head seat 8. One end of the connecting head 12 away from the quick air joint 13 penetrates into the interior of the inflating head seat 8.

A locking member 16 for locking the tracheal joint 14 is provided inside the quick air joint 13. The locking member 16 includes a ball bearing. A locking groove 17 for snap - fitting with the ball bearing is opened on the tracheal joint 2, as Figure 5 shown. During the inflation process, nitrogen fills the interior of the working cylinder and pushes out the connecting rod 10 until the limiting block 22 at the bottom end of the connecting rod 10 contacts the lower end surface of the guide 23. Then, the inflating device is removed, and the inflation process is completed.

[0046] The implementation principle of the embodiment of the present application is as follows: During assembly, first, a first sealing member 18 is placed between the inflating head handle 11 and the inflating head seat 8, and the inflating head handle 11 and the inflating head seat 8 are threadedly connected together. At this time, the first sealing member 18 is located among the inflating head handle 11, the inflating head seat 8, and the connecting rod 10. Secondly, a second sealing member 19 is placed between the inflating head seat 8 and the inflating head 7, and then the inflating head seat 8 and the inflating head 7 are threadedly connected together, thus obtaining the assembled inflating assembly 5. Similarly, a third sealing member 20 is placed between the connecting head 12 and the inflating head seat 8, the connecting head 12 is inserted into the inflating head seat 8 and threadedly connected, and then the connecting head 12 is inserted into the placement groove 15 of the quick air joint 13. The locking member 16 on the connecting head 12 is inserted into the locking groove 17 on the quick air joint 13 to achieve snap - connection, thus completing the assembly of the joint assembly 6 and forming a complete inflating tooling 1. Then, the tracheal joint of the inflating tooling 1, the trachea 2, the pressure reducing valve 3, and the nitrogen cylinder 4 are connected in sequence, thus forming a complete inflating device.

[0047] During use, first, the inflating assembly 5 of the inflating tooling 1 is sleeved on the connecting rod 10 until the inflating head 7 penetrates into the oil seal 9. When the inflating head 7 penetrates into the interior of the oil seal 9, the locking between the inflating tooling 1 and the working cylinder can be realized. Then, the switch of the nitrogen cylinder 4 is screwed clockwise, and then the value of the pressure reducing valve 3 is adjusted until the required pressure value is reached. After nitrogen fills the working cylinder, the connecting rod 10 is pushed out until the limiting block 22 at the bottom end of the connecting rod 10 contacts the lower end surface of the guide 23. At this time, the connecting rod 10 rises to the highest position. Then, the pressure reducing valve 3 and the switch of the nitrogen cylinder 4 are screwed counterclockwise until they are completely closed. Finally, the inflating tooling 1 is removed.

[0048] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
