Description

Technical Field

It uses a built-in control system or mechanical structure to achieve precise extension and retraction of the push rod within a specific range to meet the needs of different application scenarios.

[0003] In the prior art, fixed-length telescopic push rods are widely used in industrial equipment such as production lines, ventilation systems, and logistics lifting equipment to control the movement of mechanisms and improve production efficiency and automation levels. Existing fixed-length telescopic push rods are mainly composed of a support, an electric cylinder, and a guide rod. During installation, a suitable support is selected according to the size and installation requirements of the push rod, a drill is used to drill a hole in the ground or wall, and then the support is placed in the hole, and the support is fixed to the ground or wall with screws or other fasteners to ensure that the support is stable and firm, and the telescopic push rod is placed on the support to ensure that the mounting hole of the telescopic push rod is aligned with the hole on the support, and then the screws or other fasteners are passed through the mounting hole of the telescopic push rod and the hole on the support, and the screws or other fasteners are tightened with tools such as a screwdriver or a wrench to ensure that the telescopic push rod is firmly and stably connected to the support.

[0004] However, although using screws to fix the push rod to the support can ensure its stability, during long-term use, the screws and the screw holes will oxidize and rust in the air. When the push rod fails and needs to be replaced, the rusted screws may not be removed quickly and promptly, thereby affecting the replacement efficiency of the push rod. Therefore, a push rod with a fixed-length telescopic mechanism is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a push rod with a fixed-length telescopic mechanism, which can realize rapid disassembly between the mounting base and the support through the provided fastening assembly, thereby improving the replacement efficiency of the electric cylinder body.

[0010] In some embodiments, a plurality of mounting holes are formed through the upper surface of the mounting base.

[0011] Compared with the prior art, the present invention has the following significant advantages:

A plurality of slots 13 are provided on the surface of the arc tube 7 and the inner wall of the adapting groove 19. Four slots 13 are provided, which are annularly distributed on the surface of the arc tube 7 and the adapting groove 19. A plurality of U-shaped plates 14 are fixedly connected to the inner wall of the arc tube 7. A through hole is provided on one side of the plurality of U-shaped plates 14. A sliding rod 15 is slidably connected to the inner wall of the plurality of through holes. A trapezoidal block 16 is fixedly connected to one end of the plurality of sliding rods 15.

The surfaces of the plurality of trapezoidal blocks 16 are slidably connected to the inner walls of the corresponding plurality of slots 13, respectively.

[0025] like Figure 3 and 4 As shown, in one embodiment, one end of the plurality of slide bars 15 away from the trapezoidal block 16 is fixedly connected to a hemispherical block 17. The setting of the hemispherical block 17 facilitates sliding with the inclined surface of the conical block 11. The surfaces of the plurality of slide bars 15 are sleeved with springs 18, and the two ends of the plurality of springs 18 are fixedly connected to the opposite surfaces of the trapezoidal block 16 and the hemispherical block 17, respectively.
