Description

Technical Field

[0001] This utility model relates to the field of machinery, specifically to a device for preventing lead screw breakage. Background Technology

[0002] Lead screws are widely used in the mechanical field, but when used as load-bearing supports, they often break and cause the load to tip over and be damaged. A practical solution must be found. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for preventing screw breakage. It has a simple structure, is highly practical, and can effectively prevent the load from tipping over and being damaged due to screw breakage.

[0004] To achieve the above objectives, the technical solution of this utility model is a screw breakage prevention device, comprising a load-bearing object and a supporting screw, characterized in that: a protective nut is installed at the bottom of the supporting screw, a protective rod and an I-beam base are provided under the supporting screw, the protective rod is concentric with the supporting screw and has a gap, and a protective cover is provided outside the protective nut.

[0005] The protective nut is made of No. 45 alloy steel.

[0006] The advantages of this utility model are that it has a simple structure, strong practicality, can effectively prevent the load from tipping over and being damaged due to the breakage of the lead screw, is easy to manufacture and install, and increases the cost very little, but has a great effect in preventing damage.

[0008] In the picture: 100 A device for preventing lead screw breakage; 1. Load-bearing structure, 2. Support screw, 3. Protective nut, 4. Protective rod, 5. I-beam base, 6. Protective cover. Detailed Implementation

[0009] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0010] like Figure 1 As shown, this utility model discloses a screw breakage prevention device 100, including a carrier 1 and a supporting screw 2. The bottom of the supporting screw is equipped with a protective nut 3. A protective rod 4 and an I-beam base 5 are provided under the supporting screw. The protective rod is concentric with the supporting screw and has a gap. A protective cover 6 is provided outside the protective nut to keep the screw and nut clean and improve service life.

[0011] The protective nut is made of 45 alloy steel, which has high mechanical strength and impact resistance.

[0012] The working principle of this utility model is as follows: The protective nut is threaded onto the bottom of the support rod. After the protective rod is installed, the protective nut is screwed down so that it fits onto the upper part of the protective rod. In the event of a sudden breakage of the support rod or other special circumstances, the support will be supported by the protective rod when it falls, and the protective nut will prevent the support rod from tipping over and damaging the load-bearing object.

[0013] This invention can be applied to any component or equipment that moves vertically up and down via a lead screw, such as a pit-type fixed vehicle jacking machine or a mobile vehicle jacking machine.

[0014] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

Claims
