Problems solved by technology

[0004] Although the above-mentioned locking structure 100 is simple in structure, yet, when the locking screw 16 needs to be disassembled when the first element 12 and the second element 14 are separated, since the locking screw 16 has a relatively small structure, it is easy to separate from the first element 12 and the second element. The second element 14 falls off and is lost, which brings difficulties to the reassembly of the first element 12 and the second element 14; big difficulty
In addition, especially when the first component 12 and the second component 14 are inside the product, such as in a gap or a hole, the locking screw 16 may fall into the product during the assembly process, making the assembly difficult.

Embodiment Construction

[0013] The locking device of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0014] See figure 2 and image 3 , shows a locking device 20 according to a preferred embodiment of the present invention, which can be used to lock components made of metal or plastic, such as components on a computer case. The locking device 20 includes a locking member 22 , a supporting sleeve 24 , an elastic limiting member 25 and a spring 26 . One end of the locking member 22 has a locking portion 222 . The support sleeve 24 has a through hole 242 , and the through hole 242 has a first hole segment 2422 , a second hole segment 2424 and a third hole segment 2426 connected in sequence. The elastic limiter 25 is located on the stepped surface 2427 where the second hole section 2424 and the third hole section 2426 are connected. After the locking portion 222 moves along the Y1 direction and passes through the elastic limiting memb...

Abstract

The present invention discloses a locking apparatus which includes a closure and a support sleeve barrel that used to support the closure, wherein the closure is provided with locking component, and the support sleeve barrel is provided with a through hole; the through hole includes a first hole segment and a second hole segment that connecting with the first hole segment; the locking apparatus also includes a elastic spacing piece that set on the wall of the through hole. The locking component enters into the through hole and passes through the elastic spacing piece, and the elastic spacing piece limits the locking component and prevents the closure from fall off from the through hole. The above locking apparatus is not easy to fall off.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking device which can prevent the locking parts from falling off. Background technique [0002] During the assembling process of the product, in order to fix the components to each other, a locking device (such as a screw) is often used for locking. [0003] See figure 1 , a locking structure 100 comprising a first element 12 , a second element 14 and a locking screw 16 . The first element 12 has a threaded hole 122 . The second member 14 has a coupling hole 142 . The coupling hole 142 is a stepped hole, the diameter of the first hole section 1422 close to the first element 12 is smaller, and the diameter of the second hole section 1424 away from the first element 12 is larger. The locking screw 16 includes a screw head 162 , and a rod portion 164 and a threaded portion 166 are sequentially connected to the screw head 162 . The diameter of the screw head 162 is larger than that of th...
