Description of the Invention: [Technical Field] The present invention relates to a locking device, and more particularly to a locking device that prevents the locking member from coming off. [Prior Art] In the assembly 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. Referring to FIG. 1 , a locking structure 100 includes a first component 12 , a second component 14 , and a locking screw 16 . The first element 12 has a threaded bore 122. The second element 14 has a coupling aperture 142. The coupling hole 142 is a stepped hole, and the aperture of the first hole section 1422 of the first component 12 is smaller, and the aperture of the second hole section 1424 of the first component 12 is larger. The lock screw 16 includes a screw head 162, and a screw portion 164 and a thread portion 166 are sequentially connected to the screw head 162. The diameter of the screw head 162 is larger than the diameter of the first hole section 1422 and smaller than the diameter of the second hole section 1424; the diameter of the rod portion 164 is smaller than the diameter of the first hole section 1422. During assembly, the threaded portion 166 of the locking screw 16 mates with the threaded aperture 122 of the first member 12 through the engagement aperture 142 of the second member 14, thereby locking the first member 12 and the second member 14 to each other. The above-mentioned locking structure 100 has a simple structure. However, when the first component 12 and the second component 14 are separated and the locking screw 16 needs to be removed, since the locking screw 16 has a small structure, it is easy to be removed from the first component 12 and the first component. The two components 14 are lost and lost, which makes the reassembly of the first component 12 and the second component 14 difficult; and when the locking screw 16 is a non-standard component, the loss of the locking screw 16 may further bring about reassembly. Big difficulty. In addition, especially when the first member 6 1322854 member 12 and the second member 14 are in the product, the assembly of the locking screw 16 is difficult to perform in the assembly process. The inside, such as in a gap or a hole in the hole, may fall into the interior of the product. [Summary of the Invention]

A lock device includes a lock member and a support sleeve for supporting the lock member. The locking member has a locking portion with a consistent perforation. The through hole includes a first hole segment and a second hole segment connected to the first hole segment. The locking device comprises an elastic limiting element disposed on the wall of the through hole. The locking portion enters the through hole and passes through the elastic limiting member, and the elastic limiting member limits the locking portion to prevent the locking member from falling out of the through hole. In the locking process, since the through hole of the supporting sleeve has an elastic limiting component, when the locking component of the locking component passes through the elastic limiting component of the supporting sleeve, the elastic limiting component can be blocked It does not directly detach from the support sleeve. Therefore, the lock member can be prevented from falling off the support sleeve and lost during the locking and fixing process. Therefore, the above-described lock device has an advantage that it is not easily peeled off. [Embodiment] Hereinafter, the lock device of the present invention will be further described in detail with reference to the accompanying drawings and embodiments. Referring to Figures 2 and 3, there is shown a closure device 20' of 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 housing. The locking device 20 includes a locking member 22, a support sleeve 7 1322854, a barrel 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 uniform through hole 242. The through hole 242 has a first hole section 2422, a second hole section 2424 and a third hole "section 2426". The elastic limiting element 25 is located in the second hole section 2424 and the third hole. The step surface 2427 at the junction of the segment 2426. The locking portion 222 is restrained by the elastic limiting member 25 after moving through the elastic limiting member 25 in the Y1 direction, thereby preventing the locking member 22 from falling out of the through hole 242. In the manner, a flange 246 and a fixing groove 247 are formed on the hole wall of the first hole section 2422 of the support sleeve 24 far from the second hole section 2424; the third hole section 2426 of the support sleeve 24 An abutting portion 248 is formed on the outer wall surface. The locking portion 222 of the locking member 22 is a stud having an external thread. The locking member 22 is further provided with a head portion 226 at the other end opposite to the locking portion 222. The locking portion 222 is coupled to the stem portion 224 of the head portion 226. The maximum diameter of the locking portion 222 is greater than the diameter of the stem portion 224 and smaller than the diameter of the head portion 226. The aperture of the first bore portion 2422 extending through the bore 242 is greater than or equal to The diameter of the head 226 of the lock member 22, the aperture of the second bore portion 2424 is smaller than the diameter of the head 226 and The diameter of the third hole segment 2426 is smaller than the diameter of the second hole segment 2424 and greater than or equal to the maximum diameter of the locking portion 222. Further, the depth of the through hole 242 of the support sleeve 24 is preferably greater than or The length of the third hole segment 2426 is preferably greater than or equal to the length of the locking portion 222, so that the support sleeve 24 can better protect the locking member 22. The elastic limiting member 25 is hollow. The elastic piece has four elastic claws 252, 254 formed on the inner wall and the outer wall, and the minimum distance of the edge of the elastic claw 252 on the inner wall 252 to the center of the elastic limiting member 25 is smaller than the locking portion 222 of the locking member 22. The maximum diameter, the free end of the elastic claw 254 on the outer wall to the center of the elastic limiting member 25 is greater than the "hole" of the second hole portion 2424. In use, due to the free end edge of the elastic claw 253 on the outer wall The maximum distance of the center of the elastic limiting element 25 is greater than the diameter of the second hole section 2424. The elastic limiting element 25 and the inner wall of the second hole section 2424 have a certain frictional force, so as to be relatively fixed to the hole wall of the third hole section 2426. End 2427. The outer diameter of the spring 26 is larger than the aperture of the third hole section 2426 and smaller than the aperture of the second hole section 2424. The inner diameter of the magazine 26 is larger than the maximum diameter of the locking portion 222 of the locking member 22 and smaller than the locking piece. 22 The diameter of the head portion 226. The locking device 20 can firstly insert the elastic limiting member 25 into the through hole 242 from the end of the first hole portion 2422 of the supporting sleeve 24 during the assembly process, so that the elastic limiting member 25 is resisted. a stepped surface 2427 at the junction of the second bore section 2424 and the third bore section 2426; the spring 26 is then inserted into the through-through hole 242 of the support sleeve 24 such that one end of the magazine 26 abuts against the resilient stop element 25 The locking portion 222 of the locking member 22 is then passed through the spring 26 and the locking portion 222 is forced to pass the elastic limiting member 25. After the assembly of the closure device 20 is completed, it can be used to lock and fix more than two components. Referring to FIG. 4, when the locking device 20 is used, the assembled locking device 20 can be first loaded into the mounting hole 282 of the first component 28, and the fixing slot 247 is matched with the mounting hole 282 to support the support. The sleeve 24 and the member 28 are fixed to each other; then the head 226 of the lock member 22 is rotated, and the lock portion 222 is extended from the third hole portion 2426 to cooperate with the second member (not shown) 9 1322854'. Thereby locking more than two components. It is to be noted that: • the diameter of the mounting hole 282 is preferably smaller than the diameter of the outer wall of the flange 246 such that the flange 246 can be fitted into the mounting hole 282 in a riveted manner to increase the distance between the support sleeve 24 and the member 28. Binding force. In addition, it can be understood that if there is a third component 29 between the first component 28 and the second component, the abutting portion 248 on the outer wall surface of the support sleeve 24 can also resist the third component 29, thereby Element 28 is separated from third element 29 by a certain distance. In the above-mentioned locking and fixing process, since the locking portion 222 of the locking member 22 passes the elastic limiting member 25 through the supporting sleeve 24 under a certain force, it can be blocked by the elastic limiting member 25 without directly from the supporting sleeve. The sleeve 24 is disengaged, that is, the locking portion 222 forms a stop for the locking portion 222 because the elastic claw 254 is deformed and then substantially restored. Therefore, the locking portion 222 needs a certain force to be elastically restricted in the Y2 direction. The positional element 25 is retracted so that the closure device 20 prevents the closure member 22 from falling off the support sleeve 24 during the locking and fixing of more than two components, ensuring a smooth engagement of the closure and fixation process. When more than two components need to be separated and disassembled, the separate latch 222 can remain within the support sleeve 24, thereby avoiding the loss of the latch 22 and making reassembly difficult. In addition, since the locking device 20 can be fixed to the member 28, the locking device 20 as a whole is not easily lost and lost, thereby avoiding difficulties in the assembly process. Further, since the locking device 20 is provided with a spring 26, the locking member 22 can be supported by the spring 26 to prevent the locking member 22 from sinking into the third hole segment 2426 of the protruding supporting sleeve 24 before the two or more components are locked and fixed. Thus, the locking process can be brought to the door 1322854, and the kiss is shown in FIG. 5, and the locking device 30 of the preferred embodiment 2 of the present invention. lock. The device 3 includes a locking member 32, a support sleeve 34 and a plurality of elastic limit limits 35. The locking member 32, the locking seat 34 and the spring 36. The end of the lock member 32 has a locking portion 322. The lock seat 34 has a consistent perforation 342. The through hole 342 includes a first hole segment 3422 and a second hole I and 3424 connected to the first hole segment. The elastic limiting member % is fixed on the hole wall of the second hole segment. Each elastic limit The element 35 has a tilting elastic arm, and the minimum distance from the center line 3421 of the 342 to the inclined elastic arm 352 is smaller than the radius of the locking portion 322. It can be understood that the elastic limiting element 35 can be only a single. The device may have other structural changes. For example, in the locking device 20, the elastic claws 252, 254 on the elastic limiting member 25 may be omitted (four) into a ring structure, but in this case, the elastic limiting member 25 = diameter is smaller than The diameter and outer diameter of the locking portion 222 of the locking member 22 are larger than the diameter of the second j-phase; the locking portion 222 can be other structures outside the stud, such as a hook or a card slot structure; the rod portion 224 or the spring 26 25 2: The wall of the hole; and the elastic limiting member 25 can be bonded to the inner wall of the through hole 242. In summary, the invention is in accordance with the patent application requirements of the invention. Description of the invention =
