[0030] Reference Figure 1 、 2 A stand cylinder, comprising a fixed base 5, an oil cylinder body 1, a protective cover 2 and an anti-deformation rod 4. Among them, the oil cylinder body 1 comprises an oil cylinder sleeve 7 and an oil cylinder telescopic shaft 8, the oil cylinder sleeve 7 is installed on the fixed base 5, the oil cylinder telescopic shaft 8 is coaxially inserted in the oil cylinder sleeve 7 and slides along the axial direction of the oil cylinder sleeve 7, the end of the oil cylinder telescopic shaft 8 away from the oil cylinder sleeve 7 is connected with the connecting block 3, and the connecting hole 14 is arranged on the connecting block 3 for connection with other equipment.

[0031] The protective cover 2 is coaxially arranged outside the oil cylinder sleeve 7 and connected with the fixed base 5. The sidewall of the protective cover 2 is provided with a placing groove 6 penetrating the wall thickness of the protective cover 2, which can provide space for the oil supply system on the oil cylinder body 1. The outer sidewall of the oil cylinder sleeve 7 is further connected with a limiting block 15, which penetrates the placing groove 6 to prevent the relative rotation between the protective cover 2 and the oil cylinder sleeve 7.

[0032] The connecting block 3 is connected with the protective cover 2 through the anti-deformation rod 4, thereby playing a certain supporting role, strengthening the stability of the whole, and avoiding deformation affecting the extension and contraction. This design has good protection effect and can play a certain supporting role for the oil cylinder rod, avoiding deformation during supporting, having good supporting effect, and ensuring the stability of the oil cylinder extension and contraction shaft 8 during extension or retraction. One end of the anti-deformation rod 4 is fixedly connected with the connecting block 3, and the other end is inserted into the wall thickness of the protective cover 2. In other embodiments, the anti-deformation rod 4 can also penetrate the top of the protective cover 2 and be inserted into the wall thickness of the oil cylinder sleeve 7, and move along the axial direction of the oil cylinder sleeve 7 along with the oil cylinder extension and contraction shaft 8.

[0033] The outer sidewall of the oil cylinder extension and contraction shaft 8 is fixedly connected with a limiting slide column 10 along the axial direction of the oil cylinder extension and contraction shaft 8. The inner sidewall of the oil cylinder sleeve 7 is provided with a limiting slide groove 9 matched with the limiting slide column 10. The limiting slide column 10 is inserted into the limiting slide groove 9 and slidably connected with the limiting slide groove 9 along the axial direction of the oil cylinder extension and contraction shaft 8. The cooperation between the limiting slide column 10 and the limiting slide groove 9 plays a certain guiding role for the extension or retraction of the oil cylinder extension and contraction shaft 8, so that the oil cylinder extension and contraction shaft 8 can only slide in the oil cylinder sleeve 7.

[0034] Referring to Figure 3 It should be noted that a locking assembly is arranged between the limiting slide groove 9 and the limiting slide column 10 to limit the extension and contraction length of the oil cylinder extension and contraction shaft 8. Specifically, the opposite sidewalls of the limiting slide groove 9 are provided with a plurality of toothed grooves 11 arranged along the length direction of the limiting slide groove 9. The locking assembly includes a bidirectional cylinder 12 and a locking block 13. The bidirectional cylinder 12 is fixedly connected with the end of the limiting slide column 10 inserted into the limiting slide groove 9. The locking block 13 is provided with two locking blocks 13 fixedly connected with the two output ends of the bidirectional cylinder 12, respectively. The bidirectional cylinder 12 controls the two locking blocks 13 to move towards the toothed grooves 11 on the opposite sidewalls of the limiting slide groove 9, respectively. The locking block 13 is inserted into the toothed groove 11 and connected with the toothed groove 11 to lock the relative position between the limiting slide column 10 and the limiting slide groove 9, thereby locking and fixing the oil cylinder extension and contraction shaft 8. The oil cylinder extension and contraction shaft 8 can be adjusted in contraction. This design can be locked and fixed after the extension and contraction adjustment to the required length, so that the overall supporting effect is better, and sliding is avoided.

[0035] In summary, the application sets the protective cover 2 outside the oil cylinder sleeve 7 to protect the oil cylinder sleeve 7, and sets the anti-deformation rod 4 between the oil cylinder telescopic shaft 8 end and the protective cover 2 to provide guidance for the oil cylinder telescopic shaft 8 to output along the oil cylinder sleeve 7 axial direction, and provide effective support, prevent the oil cylinder telescopic shaft 8 from bending deformation in the process of supporting and using the oil cylinder body 1, and improve the supporting effect of the oil cylinder.

[0036] Further, the locking assembly is set between the limiting sliding groove 9 and the limiting sliding column 10, so that after the oil cylinder telescopic shaft 8 is adjusted to the appropriate length, the relative position between the oil cylinder telescopic shaft 8 and the oil cylinder sleeve 7 is locked, thereby avoiding the relative displacement between the oil cylinder telescopic shaft 8 and the oil cylinder sleeve 7 after the oil cylinder telescopic shaft 8 is telescoped to the position, and further improving the supporting effect of the column oil cylinder.
