The utility model provides a shock absorber connecting rod structure of anticollision buffering, includes connecting rod, inflatable guide pin bushing, and the connecting rod upper end is located inflatable guide pin bushing during inflation, its characterized in that: the connecting rod terminal surface be equipped with upwards convex screw thread section, screw thread section outside cover is established the protective sheath, the protective sheath height is less than screw thread section height, be equipped with in the protective sheath with screw thread section matched with screw thread. Compared with the prior art, the novel inflation device improves the problems in the existing inflation device, the guide sleeve is additionally arranged on the outer side of the threaded section of the connecting rod, the end face of the connecting rod is prevented from impacting the part in the inflation guide sleeve in the last step of jacking action, and the connecting rod is lifted to have a guiding effect.
Description
Technical Field
The utility model relates to the technical field of shock absorbers, in particular to a shock absorber connecting rod structure for anti-collision buffering.
Background
The inflating process of the shock absorber is to inflate a certain amount of high-pressure gas into the shock absorber after flanging, so that the connecting rod stretches out and rebounds to meet the standard of process requirements. When the shock absorber is inflated with high-pressure gas or high-purity nitrogen, the product is clamped and lifted by the inflator, the connecting rod is positioned by the inflating guide sleeve, then the oil seal is compacted to prevent air leakage, and finally the shock absorber is inflated by inflation, as shown in fig. 3 and 4. At present, in the inflation process of the shock absorber, due to the aging of inflation equipment, the position of the connecting rod is difficult to deviate, and although the inflation process can still be completed, the end face of the connecting rod easily impacts the parts in the inflation guide sleeve when a workpiece reaches the final jacking action on the equipment, so that the workpiece and the equipment are scrapped and damaged, and finally, the production cost is gradually increased.
Disclosure of Invention
The utility model provides a shock absorber connecting rod structure for anti-collision buffering, which overcomes the defects of the prior art.
In order to achieve the above purpose, the shock absorber connecting rod structure with anti-collision buffering is designed, and the shock absorber connecting rod structure comprises a connecting rod and an inflation guide sleeve, wherein the upper end of the connecting rod is positioned in the inflation guide sleeve during inflation, and the shock absorber connecting rod structure is characterized in that: the connecting rod terminal surface be equipped with upwards convex screw thread section, screw thread section outside cover is established the protective sheath, the protective sheath height is less than screw thread section height, be equipped with in the protective sheath with screw thread section matched with screw thread.
The outer side of the protective sleeve is attached to or separated from the inner wall of the inflatable guide sleeve.
The shape of the protective sleeve is cylindrical.
The lower end of the protective sleeve is pressed on the end face of the connecting rod.
Compared with the prior art, the utility model improves the problems in the prior air charging device, adds the guide sleeve on the outer side of the threaded section of the connecting rod, prevents the end surface of the connecting rod from striking the part in the air charging guide sleeve during the last step of jacking action, and plays a role in guiding the jacking of the connecting rod.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic structural view of the connecting rod and the protective sleeve according to the present utility model.
Fig. 3 is a schematic structural diagram of the utility model before modification.
Fig. 4 is a schematic structural view of the present utility model before modification.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 2, the end face of the connecting rod 1 is provided with a thread section 3 protruding upwards, a protective sleeve 4 is sleeved outside the thread section 3, the height of the protective sleeve 4 is smaller than that of the thread section 3, and threads matched with the thread section 3 are arranged in the protective sleeve 4. When the device is specifically used, the thread section 3 needs to be connected with an inflation pressure detection head of an inflator, and the upper end of the thread section 3 is exposed in the embodiment, so that the connection between the thread section 3 and the inflation pressure detection head is not affected.
The outer side of the protective sleeve 4 is attached to or separated from the inner wall of the inflatable guide sleeve 2, and the protective sleeve 4 lifts up the connecting rod 1 to a guiding effect.
The protective sheath 4 is cylindrical in shape. The lower end of the protective sleeve 4 is pressed on the end face of the connecting rod 1, plays a supporting role and is convenient for positioning the connecting rod 1.
When the shock absorber is used, the protective sleeve 4 is assembled at the thread section 3 of the connecting rod, then the shock absorber which needs to be inflated is placed in the inflator, the inflator clamps and lifts the placed product, the connecting rod is positioned through the inflation guide sleeve, then the oil seal is compacted to prevent air leakage, and finally the shock absorber is inflated through inflation. Due to the protective sleeve 4, when the shock absorber connecting rod is lifted, the protective sleeve 4 plays a role of buffering, and the end face of the connecting rod cannot strike the part in the inflatable guide sleeve.
