AI Technical Summary
Existing single-outlet viscous dampers lack a positioning structure, which causes swaying or displacement during the stress process, affecting the damping effect and potentially leading to local wear and fatigue failure due to uneven stress, posing a safety hazard.
A single-rod viscous damper with a positioning structure was designed. The first positioning sleeve and the second positioning sleeve are respectively fitted on the outside of the oil cylinder and connected to the locking block through the sliding groove. The limiting ring is locked in the limiting groove at the front end of the piston rod and fixed with bolts to ensure the stable movement of the piston rod in the oil cylinder.
This effectively prevents the piston rod from swaying and shifting during the extension and retraction process, improves the service life and safety of the damper, and ensures the stability and shock absorption effect of the structure.

Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figures 1-5 The single-rod viscous damper with a positioning structure shown includes a hydraulic cylinder 1;
[0026] The first bushing 2 and the second bushing 4 are set at both ends of the cylinder 1. The outer side of the second bushing 4 is fixedly connected to the first pin 5. The cylinder 1 is slidably connected to the piston rod 6. The piston rod 6 is connected to the cylinder 1 with the piston head 7. The other end of the piston rod 6 is fixedly connected to the second pin 8. The two sides of the cylinder 1 are fixedly connected to the slider 11.
[0027] The positioning mechanism 12 is installed outside the cylinder 1 to position the piston rod 6. The positioning mechanism 12 includes a first positioning sleeve 1201 and a second positioning sleeve 1203. The first positioning sleeve 1201 and the second positioning sleeve 1203 are respectively fitted onto the outside of the cylinder 1, and the sliding grooves 1205 inside the first positioning sleeve 1201 and the second positioning sleeve 1203 are locked onto the locking block 1202 outside the cylinder 1. At the same time, the limiting rings at the front ends of the first positioning sleeve 1201 and the second positioning sleeve 1203 are locked into the limiting grooves at the front end of the piston rod 6. Then, the first positioning sleeve 1201 and the second positioning sleeve 1203 are fixedly installed by bolts 1207. When the single-rod viscous damper is in use, the piston rod 6 will drive the first positioning sleeve 1201 and the second positioning sleeve 1203 to extend and retract together, which forms a positioning effect for the piston rod 6 and avoids shaking and displacement during the extension and retraction stroke.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the first bushing 2 and the second bushing 4 are threadedly connected to both ends of the cylinder 1. The first bushing 2 and the second bushing 4 are respectively fitted with sealing rings 3. The first bushing 2 and the second bushing 4 are respectively threadedly connected to both sides of the cylinder 1 to strengthen the firmness between them. The sealing effect of the cylinder 1 is enhanced by the sealing rings 3 fitted on the outside of the first bushing 2 and the second bushing 4.
[0029] like Figure 1 and Figure 3 As shown, a fixing sleeve 9 is fixedly connected to the outer rear side of the cylinder 1. A rubber pad 10 is pasted on the inner side of the fixing sleeve 9. The rubber pad 10 pasted on the inner side of the fixing sleeve 9 can buffer the first positioning sleeve 1201 and the second positioning sleeve 1203 from contacting the rubber pad 10 during the extension and retraction of the piston rod 6.
[0030] like Figure 5 As shown, a locking block 1202 is fixedly connected to the inner side of the first positioning sleeve 1201, and a locking groove 1204 is provided on the inner surface of the second positioning sleeve 1203. The first positioning sleeve 1201 and the second positioning sleeve 1203 are movably locked together. The locking block 1202 on the inner side of the first positioning sleeve 1201 and the locking groove 1204 on the inner side of the second positioning sleeve 1203 form a docking action to enhance the firmness between the two.
[0031] like Figure 5As shown, the inner surfaces of the first positioning sleeve 1201 and the second positioning sleeve 1203 are respectively provided with sliding grooves 1205. The sliding grooves 1205 are used in conjunction with the external slider 11 of the oil cylinder 1. The first positioning sleeve 1201, the second positioning sleeve 1203 and the oil cylinder 1 are limited to sliding. During the extension and retraction of the piston rod 6, the first positioning sleeve 1201 and the second positioning sleeve 1203 are limited to sliding outside the external slider 11 of the piston rod 6 through the internal sliding grooves 1205, which improves the stability of the first positioning sleeve 1201 and the second positioning sleeve 1203 during the movement.
[0032] like Figure 5 As shown, a limiting ring is fixedly connected to the inner front end of the first positioning sleeve 1201 and the second positioning sleeve 1203. A limiting groove is opened on the outer front end of the piston rod 6. The limiting ring and the limiting groove are used in conjunction. A fixing block 1206 is fixedly connected to the outer front end and the outer rear end of the first positioning sleeve 1201 and the second positioning sleeve 1203 respectively. A bolt 1207 passes through the external thread of the fixing block 1206. The limiting ring on the inner front end of the first positioning sleeve 1201 and the second positioning sleeve 1203 can be locked in the limiting groove opened on the front end surface of the piston rod 6, which improves the firmness of the first positioning sleeve 1201 and the second positioning sleeve 1203. Then, the first positioning sleeve 1201 and the second positioning sleeve 1203 are fixed by the bolt 1207.
[0033] The working principle of this utility model is as follows: First, the first positioning sleeve 1201 and the second positioning sleeve 1203 are respectively placed on the outside of the oil cylinder 1. The locking block 1202 on the inside of the first positioning sleeve 1201 is inserted into the locking groove 1204 on the inside of the second positioning sleeve 1203 to form a mating effect, strengthening the firmness between the two. At the same time, the sliding groove 1205 inside the first positioning sleeve 1201 and the second positioning sleeve 1203 is engaged with the locking block 1202 on the outside of the oil cylinder 1. The limiting ring at the front end of the first positioning sleeve 1201 and the second positioning sleeve 1203 is engaged in the limiting groove on the outside of the front end of the piston rod 6, strengthening the firmness of the first positioning sleeve 1201 and the second positioning sleeve 1203. Then, a bolt 1207 is used to pass through the front and rear ends of the first positioning sleeve 1201 and the second positioning sleeve 1203. Inside the fixed block 1206, the first positioning sleeve 1201 and the second positioning sleeve 1203 are fixedly connected. Then, the entire single-rod viscous damper is installed at the designated position for shock absorption. When the single-rod viscous damper is subjected to vibration, the piston head 7 begins to reciprocate within the cylinder 1. Due to the movement of the piston head 7, the viscous damping medium inside the piston head 7 generates a pressure difference, thereby forming a damping force. During the extension and retraction of the piston rod 6 within the cylinder 1, the first positioning sleeve 1201 and the second positioning sleeve 1203 extend and retract together, thus creating a positioning effect for the piston rod 6 and preventing swaying and displacement during the extension and retraction stroke, which would affect its shock absorption effect. In this way, the use of the single-rod viscous damper with a positioning structure is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
