Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire rope slings, and in particular relates to a steel wire quick-release self-locking device. Background Art

[0002] Among aircraft parts, steel cables are important components for controlling aircraft movements. After being manufactured, steel cables need to be tested for tension. At this time, one end of the steel cables needs to be tied and fixed. However, the number of steel cables that need to be tested is huge. The tying and fixing is not only cumbersome, but also has a poor fixing effect. Moreover, after being stretched, the fixed end becomes tighter due to the stretching, making it difficult to remove. When mechanical clamping is used for fixing, the safety and fastening strength are low, which can easily lead to detection failure and even threaten personal safety. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a steel cable quick-release self-locking device which is quick to install and easy to disassemble.

[0004] The utility model is realized by the following technical solutions:

[0005] A quick-release self-locking device for a steel cable comprises an outer tube and an inner core; the outer tube is a hollow cone with upper and lower openings; the inner core is movably installed in the outer tube and matches the inner conical surface of the outer tube; a plurality of grooves are arranged on the side surface of the inner core; the side surfaces of the inner core are arranged with grooves opposite to each other in pairs; the taper of the outer tube and the inner core is not less than 5°; pull rings are installed on both sides of the outer tube by screws.

[0012] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0013] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0014] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. It should be noted that the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0015] like Figure 1 , Figure 2 The steel cable quick-release self-locking device shown comprises: an outer cylinder 1, an inner cylinder 2, a screw 3, a pull ring 4, and a steel cable 5.

[0016] The outer cylinder 1 is a hollow cone with openings at the top and bottom.

[0017] The inner core 2 is movably installed in the outer cylinder 1 and matches with the inner conical surface of the outer cylinder 1; grooves are arranged on the side surfaces of the inner core 2 in pairs.

[0018] The taper of the outer cylinder 1 and the inner core 2 is not less than 5°.

[0019] The pull ring 4 is mounted on the outer tube 1 by means of screws 3 .

[0020] Working principle:

[0021] When in use, fix the pull ring 4, pass the steel cable 5 through the small end of the outer tube 1, and insert it into the groove of the inner core 2, then insert the steel cable 5 into the opposite groove of the inner core 2 in the reverse direction, pass it out from the small end of the outer tube 1, and finally put the inner core 2 into the outer tube 1, and the installation is completed.

[0022] When it is necessary to disassemble, it is only necessary to apply a thrust to the inner core 2 on one side of the small end of the outer cylinder 1 so that the inner core 2 is pushed out from the large end of the outer cylinder 1, and the steel cable 5 can be disassembled.

[0023] The protection scope of the present utility model is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
