Abstract

The invention discloses a combined nut locked by a spring, which comprises a first nut, a second nut, a fixed cylinder, a compression cylinder, a spring, a movable rod and a connecting rod. A The first threaded hole, the upper end of the first nut is provided with a fixed tube, the fixed tube surrounds the upper opening end of the first threaded hole, the inside of the fixed tube is provided with a spring, the upper end of the spring is fixed with the fixed tube, and the The lower end is connected with several movable rods arranged horizontally, all the movable rods are located on the same horizontal plane, and several vertically arranged guide grooves are provided on the side wall of the fixed cylinder. In the present invention, the first nut and the second nut are sequentially screwed on the same screw rod, so that the spring stretches and hoops the screw rod, and the first nut and the second nut are fixed by a connecting rod, so that the combined nut can rely on pulling The extended spring is locked and is not easy to loosen, which ensures the effectiveness of the combined nut.

Description

[Technical field] [0001] The present invention relates to the technical field of fasteners, in particular the technical field of combined nuts. 【Background technique】 [0002] The nut is a common fastener, which is mainly used in conjunction with the screw or bolt. Existing nuts will be loose during use because of vibration, etc., eventually make the nut failure will bring certain safety hazards. [Summary] [0003] It is an object of the present invention to solve the problems in the prior art, and propose a combined nut that utilizes spring lock, which can make the nut are not easy to loosen. [0004] In order to achieve the above object, the present invention proposes a combined nut using spring lock, including a first nut, a second nut, a fixed tube, a compactor, a spring, a movable rod, a connecting rod, and the first nut. A first threaded hole is provided on the axis, and the upper end of the first nut is provided with a fixing tube, and the fixed barrel encloses the first ...
