Problems solved by technology
[0002] At present, there are various self-locking structures, the structures are different, and the principles are not the same. Some structures are simple, but the self-locking structure is not strong enough, and the self-locking structure with better self-locking performance is more complicated in structure, and even some Parts are difficult to process, which increases the cost of production

Embodiment Construction
[0025] see Figure 1 to Figure 7 , In a preferred embodiment of the present invention, a self-locking structure includes a sliding block 1 , a limiting block 2 , a rotating member 3 , an engaging member 4 , a clamping strip 5 and a guide member 6 .
[0026] A first groove 11 is provided on one side of the slider 1, and the first groove 11 connects the upper and lower surfaces of the slider 1; a first stopper 12 is provided on the bottom surface of the first groove 11 , the first limiting portion 12 is in the form of a baffle. Preferably, the upper surface of the first limiting portion 12 is coplanar with the upper surface of the slider 1 .
[0027] The limiting block 2 is arranged under the slider 1 , connected with the slider 1 through the guide 6 , and can slide up and down relative to the slider 1 along the guide 6 . A first protrusion 21 is provided on the upper part of the limiting block 2, and when the first protrusion 21 slides on the limiting block 2 and is closest t...

The invention provides a self-locking structure. The self-locking structure comprises a slide block, a limiting block, guide parts, a rotary part, a blocking part and a blocking strip, wherein the limiting block is arranged at one side of the slide block, can pass through the guide parts to slide relative to the slide block, and can block the rotary part while being closet to the slide block; the rotary part is in rotary connection to the slide block; the blocking part is also in rotary connection to the rotary part, but is not connected to the slide block; two rotary centers are not coaxial, so that the rotary part can drive the blocking part to rotate around the rotary center of the rotary part relative to the slide block; a first limiting part is arranged on the slide block; a second limiting part is arranged on the rotary part; the blocking strip is distributed at one side of the slide block, is parallel to the guide parts, and adopts an oblique-tooth structure for blocking the blocking part which is in contact with the blocking strip; and when the limiting part is closest to the slide block and the blocking strip blocks the blocking part, the limiting block blocks the rotary part, so that the rotary part and the blocking part cannot rotate, and therefore, the self-locking structure realizes self-locking. The self-locking structure is designed by utilizing the gravity principle, is simple in structure, is good in self-locking performance, is safe and reliable, and is good in practicability.
Description
【Technical field】 [0001] The invention relates to the field of locking devices, in particular to a self-locking structure for an up and down sliding device. 【Background technique】 [0002] At present, there are various self-locking structures, the structures are different, and the principles are not the same. Some structures are simple, but the self-locking structure is not strong enough, and the self-locking structure with better self-locking performance is more complicated in structure, and even some Parts are difficult to machine, increasing the cost of production. Therefore, it is necessary to provide a self-locking structure with simple structure, convenient use, good self-locking performance, low production cost and strong practicability. 【Content of invention】 [0003] In order to achieve the above purpose, the technical solution adopted by the present invention is: a self-locking structure, the self-locking structure includes a slider, a limit block, a guide, a ro...
