[0039] The following is a detailed description of the scope of protection of the present invention in conjunction with the embodiments and accompanying drawings of the present invention. It should be noted that the following descriptions are all examples, and their purpose is to facilitate understanding rather than to limit the scope of protection of the present invention. All routine changes made based on the embodiments should fall within the scope of protection of the present invention.

[0040] A lock assembly structure mainly consists of a lock body 100, a first lock member 310 and a driving member 500 installed in the lock body 100.

[0041] A lock cavity 104 extending along a first direction is formed in the lock body 100 , and a first side opening 102 arranged forward along a second direction is formed on a side wall of the lock body 100 .

[0042] The first locking element 310 is at least partially accommodated in the lock cavity 104, and is assembled into the lock cavity 104 from the lock cavity opening 105 of the lock cavity 104 so that the first locking element 310 is preliminarily positioned in the lock cavity 104; preliminarily positioned means that after the first locking element 310 is assembled into the lock cavity 104 from the lock cavity opening 105, its four sides are limited by the side walls of the lock cavity 104 and cannot move or the movement space is very small, but the first locking element 310 is allowed to move in at least one of the two directions in the first direction.

[0043] The driving member 500 is assembled into the lock cavity 104 from the first side opening 102 and connected to the first lock member 310 or the lock body 100 or connected to both at the same time, preferably connected to each other in a snap-fit ​​manner, so that the assembled driving member 500 is relatively fixedly connected to the lock body 100; and the driving member 500 also limits the first lock member 310 to prevent it from escaping from the lock cavity 104. This can be that the driving member 500 is directly fixed to the first lock member 310, or the driving member 500 is fixed to the lock body 100 and the first lock member 310 is limited by the concave-convex structure, thereby achieving the purpose of limiting the bidirectional movement of the first lock member 310 in the second direction by using the driving member 500, and finally fixing the first lock member 310 in the lock body 100. The snap-fit ​​manner can also avoid the use of screws or glue, and the assembly is convenient and the connection is firm.

[0044] Preferably, the driving member 500 is further provided with a first tongue member 501 for driving the first locking member 310 to move in the lock body 100. After assembly, the first tongue member 501 is inserted into the first side opening 102 for user operation.

[0045] like Figure 1-5 As shown, a lock body of a protective lock that is assembled without screws or bonding methods (such as gluing or hot melting) can be formed into various types of child protection locks. In this embodiment, it is formed into a door stop that can be used to lock the door leaf. The door stop is used to be fixed on the door leaf and, when needed, contacts the ground to lock the door leaf open / closed.

[0046] like Figure 1 The lock body is structurally comprised of a lock body 100 and a cavity cover 200. A lock cavity 104 extending in a first direction is formed in the lock body 100. The cavity cover 200 is assembled at a lock cavity opening 105 of the lock cavity 104 to seal the lock cavity opening 105. The lock cavity opening 105 is arranged downwardly along a second direction. Lock surfaces 101 are respectively formed on two opposing surfaces of the lock body 100. A first side opening 102 facing forward is provided on one lock surface 101, and a second side opening 103 facing backward is provided on the other lock surface 101 (i.e., on a side wall of the lock body 100 opposite to the first side opening 102). The lock cavity opening 105 is formed at the bottom surface of the lock body 100 and faces downwardly.

[0047] like Figure 2 As shown, the first direction refers to Figure 2 The vertical direction, the second direction, and the third direction refer to the front-to-back direction, respectively. The lock cavity 104 is generally hollow and formed within the lock body 100 along its length (i.e., the vertical direction), such that the first locking element 310 is restrained in the left-right and front-to-back directions by the sidewalls of the lock cavity 104. The lock cavity 104 has one end (i.e., the end closest to the upper side) that is closed, and the other end (i.e., the end closest to the lower side) that is open, forming a lock cavity opening 105.

[0048] The lock body also includes a locking assembly 300 and a driving member 500. The lock cavity 104 is used to accommodate all or part of the locking assembly 300 and the driving member 500 therein. The locking assembly 300 is used to be accommodated in the lock cavity 104 and to be displaced, such as moving back and forth, so as to achieve the locking or unlocking operation of the lock; the driving member 500 is exposed at the first side opening 102 for the user to operate it and drive the locking assembly 300 to move; the locking assembly 300 is further composed of a first locking member 310 and a second locking member 320. The second locking member 320 is connected to the first locking member 310 to move therewith, and the driving member 500 is snapped onto the second locking member 320.

[0049] The driving member 500 is further provided with a first tongue member 501 for driving the locking assembly 300 to move. After assembly, the first tongue member 501 is inserted into the first side opening 102 for a user to operate the first tongue member 501 .

[0050] In this embodiment, the first side opening 102 and the second side opening 103 are both elongated holes in the vertical direction, that is, their length in the vertical direction is greater than the length of the corresponding parts of the first tongue 501 and the second tongue 502 that pass through them, so that the first tongue 501 and the second tongue 502 can be arranged to slide back and forth in the vertical direction within the two side openings, so that the user can lock or unlock the lock body by operating the up and down sliding of the two tongues. In addition, the driving member 500 also has a lining plate 504 that can cover the first side opening 102 to prevent the internal structure from being directly visible. When the first tongue 501 moves downward, the lining plate can also abut against the inner wall of the lock body 100 to play a guiding role. Figure 4 As shown, the second tongue piece 502 and the second clamping piece 503 are protruded on the left side of the lining plate 504, and the first tongue piece 501 is protruded on the right side thereof.

[0051] In other embodiments, the first tongue 501 and the second tongue 502 may also be changed from an up-and-down sliding setting to a left-and-right sliding setting, or may be simultaneously slid in the up-and-down directions and the left-and-right directions to form a movable setting that can slide obliquely or along a curved track.

[0052] Preferably, the first side opening 102 is a D-shaped hole, and the second side opening 103 is a rectangular hole.

[0053] In this embodiment, the locking assembly 300 is composed of a first locking member 310 and a second locking member 320. The second locking member 320 is assembled with the first locking member 310 to form the locking assembly 300. The second locking member 320 approaches the first locking member 310 from the rear side of the first locking member 310, and after assembly, it moves upward, thereby forming an assembled connection between the first locking member 310 and the second locking member 320. The bolt member 330 is movably disposed on the first locking member 310 and is driven by the second locking member 320. When the second locking member 320 moves, it drives the bolt member 330 to unlock the lock body.

[0054] like Figure 6As shown, a pivot 317 is protruded from the first lock member 310, and a pivot hole 331 is provided in the middle of the lock tongue member 330. The pivot hole 331 is sleeved on the pivot 317 so that the lock tongue member 330 can be pivotally mounted on the first lock member 310. When the user pushes the first tongue member 501 or the second tongue member 502, the second lock member 320 can be driven to move downward relative to the first lock member 310, thereby driving the lock tongue member 330 to rotate around the pivot 317 on the first lock member 310, so that the lock tongue 332 provided at the upper end of the lock tongue member 330 retracts and unlocks. Among them, a driving arm 328 is provided at the upper end of the second lock member 320. When the second lock member 320 moves downward, the driving arm 328 acts on the outer side of the lower end of the lock tongue member 330 to drive the lower end of the lock tongue member 330 to rotate inward. Preferably, a return spring ( Figure 6 For this purpose, a spring fixing seat is provided on the first lock member 310 and a spring retaining seat is provided on the inner side of the lower end of the lock tongue member 330.

[0055] like Figure 2-5 As shown, the first lock member 310 includes a first body 311, which is provided with a first mounting opening 312 extending therethrough. A first mounting cavity 313 is provided on the rear side of the top wall of the first mounting opening 312, and a first protrusion 314 is provided on the front side of the top wall. In this embodiment, the first mounting opening 312 is a through hole. A second connecting portion 315 for connecting to the cavity cover 200 is provided at the top of the first body 311. The cavity cover 200 has a connector 201 formed at its upper end and a cover body 202 at its lower end. The connector 201 is provided with a first connecting portion 203, which is configured to connect to the second connecting portion 315.

[0056] like Figure 2-5 As shown, the second lock member 320 includes a second body 321. A second mounting portion 322 is provided on the second body 321, which can be assembled into the first mounting opening 312. A second mounting opening 323 is provided through the second mounting portion 322. A second mounting cavity 324 is recessed above the top wall of the second mounting portion 322. A second protrusion 325 is provided on the front side of the second mounting cavity 324. A first latch 326 is provided below the top wall of the second mounting portion 322. The first latch 326 is provided through the second mounting cavity 324. A return spring post 327 is provided at the lower end of the second mounting portion 322. A return spring (not shown) has one end fixedly mounted on the return spring post 327 and the other end located in the spring cavity 316 of the first lock member 310. The return spring ensures that the second lock member 320 is in the upper position under the action of the return spring in the absence of external force. When the return spring is pushed downward, the return spring is compressed.

[0057] In which, the second locking member 320 is entirely accommodated in the first mounting opening 312 of the first locking member 310, and a first latching protrusion 401 and a second latching protrusion 402 are respectively provided on both sides of the second locking member 320. After assembly, the first latching protrusion 401 and the second latching protrusion 402 respectively abut against the two sides of the side wall of the first mounting opening 312, and the first side wall 403 located between the first latching protrusion 401 and the second latching protrusion 402 is located on the inner side of the side wall of the first mounting opening 312.

[0058] like Figure 2-5 As shown, a second latching member 503 is provided on the driving member 500. The second latching member 503 is formed by a latching tongue and has appropriate elasticity. It can be bent or deformed appropriately toward or toward to achieve engagement or separation. The second latching member 503 is used to be engaged with the first latching member 326 formed by the latching hole, thereby achieving mutual engagement between the driving member 500 and the second locking member 320, that is, achieving mutual engagement between the driving member 500 and the driving member 500. Of course, in other embodiments, the first latching member 326 can also be formed by another latching tongue symmetrically arranged with the second latching member 503, which can also achieve the purpose of engagement between the two.

[0059] The lock body of this embodiment is assembled as follows:

[0060] First, the second lock member 320 is assembled onto the first lock member 310 to form the lock assembly 300. Specifically, the second lock member 320 is first assembled from the rear of the first lock member 310, and then the second lock member 320 is moved upward a suitable distance so that the first protrusion 314 is positioned within the second mounting cavity 324 (this process can be initiated by the user or driven by a return spring). This also includes installing the bolt member 330 onto the first lock member 310 and the second lock member 320.

[0061] Secondly, the assembled locking assembly 300 is installed as a whole into the lock body 100 from bottom to top, that is, assembled into the lock cavity 104 from the lock cavity opening 105. Due to the structural size of the locking assembly 300, it can be initially positioned in the lock cavity 104.

[0062] Finally, the driving member 500 is assembled into the lock cavity 104 from the first side opening 102, and the driving member 500 is engaged with the second lock member 320. After the second tongue member 502 passes through the first and second lock members, it is exposed at the second side opening 103 on the rear surface, so that the driving member 500 also limits the locking assembly 300 to prevent it from escaping from the lock cavity 104.

[0063] The above is the assembly process of the main structure of the lock body. It can be seen that no screws or glue are required for fixation. Instead, assembly and connection are achieved by redesigning various functional structures.

[0064] Among them, the assembly of non-important parts is not described in the above steps because their assembly order is variable. For example, the cavity cover 200 is assembled to the lower end of the first locking member 310 in the first step, or the cavity cover 200 is installed after the last assembly step is completed.
