Description

Technical Field

[0001] The utility model relates to the field of split shock absorbers, in particular to a split shock absorber. Background Art

[0002] Split shock absorbers are a common type of shock absorber in automobile suspension systems, also known as adjustable shock absorbers. Unlike traditional integrated shock absorbers, split shock absorbers separate the spring and damper of the shock absorber into two independent components.

[0003] In the prior art, on the one hand, the shock absorber rod of the existing split shock absorber is an integrated type. If the parts in the shock absorber rod need to be maintained, tools need to be used for cleaning, but the use range of the tools is limited, and the shock absorber rod cannot be disassembled and cleaned, which reduces the maintenance of the shock absorber rod to a certain extent. On the other hand, the sliding part between the piston rod and the shock absorber rod generally uses a dust cover to prevent oil and dirt from entering the shock absorber rod, but the dust cover will cause wear and affect subsequent use after long-term use. In the subsequent disassembly and assembly process, special tools need to be used to disassemble the shock absorber top glue and remove the dust cover, which is relatively cumbersome in actual operation. Therefore, a split shock absorber is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a split shock absorber, aiming to improve the problem in the prior art that the shock absorber rod cannot be split and cleaned.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a split shock absorber, including a socket, the top of the socket is fixedly connected to a fixed block, the side wall of the socket is fixedly connected to a plug plate, the outer wall of the plug plate is plugged with a sleeve, the top of the sleeve is fixedly connected to a round tube, the inner wall of the bottom end of the round tube is elastically connected to a clamping plate through a reset spring, and a piston mechanism is provided on the socket and the inner wall of the sleeve.

[0006] As a further description of the above technical solution:

[0007] The top end of the insert sleeve contacts with a contact ring, the bottom end of the contact ring is fixedly connected with a square frame, and the inner wall of the right end of the square frame is elastically connected with a limit block through a positioning spring.

[0008] As a further description of the above technical solution:

[0009] The inner wall at the right end of the square frame is fixedly connected to one end of a positioning spring, and the other end of the positioning spring is fixedly connected to the right end of the limiting block.

[0010] As a further description of the above technical solution:

[0011] The limit blocks respectively penetrate and are slidably connected to the inner walls of the square frame and the contact ring.

[0012] As a further description of the above technical solution:

[0013] The limiting block is plugged into the inner side wall of the plug sleeve.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the bottom end of the circular tube is fixedly connected to one end of a return spring, and the other end of the return spring is fixedly connected to the bottom end of the clamping plate.

[0016] As a further description of the above technical solution:

[0017] The clamping plate is slidably connected to the inner wall of the round tube, and the clamping plate is clamped with the top end of the fixing block.

[0018] As a further description of the above technical solution:

[0019] The piston mechanism comprises a piston tube, which respectively penetrates and is slidably connected to the inner walls of the insert sleeve and the sleeve, and the outer wall of the piston tube is in contact with the contact ring.

[0020] The utility model has the following beneficial effects:

[0032] Reference Figure 2-Figure 5 The top of the socket 1 is in contact with a contact ring 9, and the sleeve 4 has the same contact ring 9 as the socket 1. Two groups of contact rings 9 are provided, and the two groups are spliced ​​to prevent oil from entering the socket 1 and the sleeve 4. The bottom end of the contact ring 9 is fixedly connected with a square frame 10. The socket 1 is provided with a slot for the square frame 10 to move, so that the square frame 10 can be inserted into the slot, and the square frame 10 can also slide along the slot of the socket 1. The inner wall of the right end of the square frame 10 is elastically connected to the limit block 12 through a positioning spring 11.

[0033] Reference Figure 1-Figure 3The inner wall of the right end of the square frame 10 is fixedly connected to one end of the positioning spring 11. When the limit block 12 moves to the right, the positioning spring 11 will be compressed. When resetting, the elastic force of the positioning spring 11 is used to reset the limit block 12. The other end of the positioning spring 11 is fixedly connected to the right end of the limit block 12. The limit block 12 passes through and is slidably connected to the inner walls of the square frame 10 and the contact ring 9 respectively. The square frame 10 and the contact ring 9 are respectively provided with notches corresponding to the limit block 12. The limit block 12 is plugged into the inner side wall of the socket 1. The inner wall of the notch of the socket 1 is provided with a notch corresponding to the limit block 12, so that the limit block 12 can be plugged into it to limit the contact ring 9.

[0034] Reference Figure 1-Figure 3 The inner wall of the bottom end of the round tube 5 is fixedly connected to one end of the return spring 6. When the clamping plate 7 moves upward, the return spring 6 will be stretched. When resetting, the elastic force of the return spring 6 is used to reset the clamping plate 7. The other end of the return spring 6 is fixedly connected to the bottom end of the clamping plate 7. The clamping plate 7 is slidably connected to the inner wall of the round tube 5. The clamping plate 7 is clamped with the top of the fixed block 2. The piston mechanism includes a piston tube 8. The piston tube 8 is an important component of the existing split shock absorber. No more details are given here. The piston tube 8 passes through and is slidably connected to the inner walls of the sleeve 1 and the sleeve 4 respectively, and the outer wall of the piston tube 8 is in contact with the contact ring 9.

[0035] Working principle: First, when maintenance is needed on the socket 1 and the sleeve 4, just move the card plate 7 upward through the notch of the fixed block 2 to separate the card plate 7 from the top notch of the fixed block 2. At this time, the reset spring 6 is in a stretched state, and then the socket 1 and the sleeve 4 are separated, and the notches on the side walls of the card plate 3 and the sleeve 4 are separated, so that the round tube 5 can be separated from the notch of the fixed block 2, and the two groups of contact rings 9 are also separated. Finally, release the card plate 7 and use the reverse elastic force of the reset spring 6 to reset the card plate 7, and the socket 1 and the sleeve 4 can be maintained.

[0036] After the maintenance is completed, when the socket 1 and the sleeve 4 need to be spliced ​​and used, it is only necessary to insert the plug plate 3 on the socket 1 into the slot of the sleeve 4, and at the same time move the clamping plate 7 upward according to the above steps in the first paragraph, so that the clamping plate 7 will not block the round tube 5 from entering the slot of the fixed block 2. When the round tube 5 enters the slot of the fixed block 2, the clamping plate 7 coincides with the top slot of the fixed block 2, release the clamping plate 7 and let the clamping plate 7 be inserted into the top slot of the fixed block 2 to complete the limiting of the socket 1 and the sleeve 4.

[0037] When the contact ring 9 needs to be replaced after long-term use, it is only necessary to press the limit block 12 to move it to the right and compress the positioning spring 11 to separate the limit block 12 from the inner side wall of the sleeve 1, and then remove the entire contact ring 9 from the top of the sleeve 1. The contact point between the contact ring 9 and the piston tube 8 can be cleaned. When the contact ring 9 needs to be installed, it is only necessary to press the limit block 12 in advance to allow the limit block 12 to enter the frame 10, and then remove the frame 10 from the top groove of the sleeve 1. Insert the right end of the opening, and after entering the slot, use the inner wall to continuously squeeze the limit block 12, then move the contact ring 9 and the frame 10 to the left along the slot of the socket 1, so that the two groups of contact rings 9 can be spliced ​​to block oil stains. When the limit block 12 coincides with the slot of the inner side wall of the socket 1, use the reverse elastic force of the positioning spring 11 to move the limit block 12 to the left and reset it, so that the limit block 12 is plugged into the slot of the inner side wall of the socket 1 to limit the entire contact ring 9 and complete the replacement process.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
