Description

Technical Field

[0001] The present application relates to the technical field of lock design, and in particular to a lock and door assembly. Background Art

[0002] In the related art, the lock body of the lock includes a slider buckle and a spring. When the buckle is inserted into the lock body, the buckle pushes the sliding buckle to retract; then, when the buckle is inserted into place, the spring pushes the sliding buckle to extend, and then the buckle is locked by the way that the buckle's clamping part is hooked and matched with the buckle. Due to the size limitation of the lock body, it is sometimes inconvenient to set a spring with a larger size and greater elastic force. As a result, the force of the spring acting on the clamping part sometimes cannot meet specific usage requirements. Utility Model Content

[0038] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0039] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0040] The present application embodiment provides a lock. Figures 1 to 8 The lock 100 provided in the embodiment of the present application includes: a lock body 110 and a lock buckle 120.

[0041] The lock body 110 includes a base 111, a rotating body 112 and an elastic member 113. For example, the elastic member 113 is a spring. Alternatively, the elastic member 113 is any other element capable of generating a restoring force.

[0042] The rotating body 112 includes a rotating part 1121, an elastic member connecting part 1122 and a clamping part 1123. The rotating part 1121 is rotatably connected to the base 111. The distance between the clamping part 1123 and the rotating axis of the rotating part 1121 is smaller than the distance between the elastic member connecting part 1122 and the rotating axis of the rotating part 1121.

[0043] The engaging portion 1123 can move between a first position and a second position around the rotation axis of the rotating portion 1121 . When the lock 100 is in a locked state, the engaging portion 1123 is located at the first position and is engaged with the lock buckle 120 inserted into the lock body 110 .

[0044] The elastic member 113 is respectively connected to the elastic member connecting portion 1122 and the base 111. The elastic member 113 is used to apply a force to the rotating body 112 to enable the clamping portion 1123 to move from the second position to the first position when the clamping portion 1123 deviates from the first position.

[0045] In this way, in the embodiment of the present application, the rotating body 112 can rotate around the rotating shaft of the rotating part 1121, so that the clamping part 1123 moves between the first position and the second position around the rotating shaft of the rotating part 1121. When the lock 100 is in the locked state, the clamping part 1123 is located at the first position, and the clamping part 1123 is clamped with the lock buckle 120 inserted into the lock body 110. In addition, during the process of unlocking or locking, the lock buckle 120 can overcome the elastic force of the elastic member 113, thereby making the clamping part 1123 move from the first position to the second position, so that the lock buckle 120 is separated from the clamping part 1123, or is clamped with the clamping part 1123.

[0046] Since the distance between the clamping portion 1123 and the rotation axis of the rotating portion 1121 is smaller than the distance between the elastic member connecting portion 1122 and the rotation axis of the rotating portion 1121 , a lever amplification effect can be achieved, thereby increasing the force acting on the clamping portion 1123 by the elastic member 113 .

[0047] refer to Figures 5 to 8In some embodiments, the lock buckle 120 is provided with a snap-fitting protrusion 121, and the snap-fitting portion 1123 is provided with a snap-fitting groove 11231. When the lock 100 is in the locked state, the snap-fitting protrusion 121 is accommodated in the snap-fitting groove 11231. In other words, the lock buckle 120 and the lock body 110 can be snap-fitted by accommodating the snap-fitting protrusion 121 in the snap-fitting groove 11231, so that the lock 100 is switched to the locked state.

[0048] refer to Figures 5 to 8 In some embodiments, the engaging protrusion 121 includes a first guiding inclined surface 122 and a second guiding inclined surface 123 that are separated from each other; the engaging groove 11231 includes a first stop surface 11232 and a second stop surface 11233 that are opposite to each other. When the lock 100 is in a locked state, the first guiding inclined surface 122 is opposite to the second stop surface 11233, and the second guiding inclined surface 123 is opposite to the first stop surface 11232. In the insertion direction of the lock buckle 120, the first guiding inclined surface 122 is engaged with the second stop surface 11233, and the second guiding inclined surface 123 is engaged with the first stop surface 11232. In this way, the lock buckle 120 can be locked and limited by the first guiding inclined surface 122 and the second stop surface 11233, and the second guiding inclined surface 123 and the first stop surface 11232.

[0049] Exemplarily, during the insertion of the lock buckle 120 into the lock body 110, the first guide slope 122 of the lock buckle 120 abuts against the clamping portion 1123, thereby pushing the clamping portion 1123 to rotate around the rotation axis of the rotating portion 1121, so that the clamping portion 1123 moves from the first position to the second position. At the same time, during the rotation of the rotating body 112, the elastic member connecting portion 1122 can squeeze or stretch the elastic member 113, and the elastic member 113 can store elastic energy. Further, after the lock buckle 120 is inserted into place, the elastic member 113 releases elastic energy, so that the clamping portion 1123 moves from the second position to the first position and is clamped with the lock buckle 120.

[0050] In addition, when the lock buckle 120 is withdrawn from the lock body 110 in the direction opposite to the insertion direction, the second guide slope 123 of the lock buckle 120 abuts against the first stop surface 11232, thereby pushing the clamping portion 1123 to rotate around the rotation axis of the rotating portion 1121, so that the clamping portion 1123 moves from the first position to the second position. At the same time, during the rotation of the rotating body 112, the elastic member connecting portion 1122 can squeeze or stretch the elastic member 113, and the elastic member 113 can store elastic energy. Further, after the lock buckle 120 is separated from the clamping portion 1123, the elastic member 113 releases elastic energy, so that the clamping portion 1123 moves from the second position to the first position, that is, returns to the initial state when the lock buckle 120 is not inserted.

[0051] refer to Figure 4 In some embodiments, the rotating portion 1121 is located between the elastic member connecting portion 1122 and the clamping portion 1123. Figure 2 In some embodiments, the base 111 is provided with an abutting surface 1111. The abutting surface 1111 is used to abut against the rotating body 112 when the clamping portion 1123 moves to the first position. Thus, the clamping portion 1123 can move to the first position at most during the process of moving from the second position to the first position. In other words, the abutting surface 1111 is used to limit the limit position of the clamping portion 1123 during the process of moving from the second position to the first position.

[0052] refer to Figure 2 and Figure 4 In some embodiments, the abutting surface 1111 and the elastic member connecting portion 1122 are respectively located on two sides of the rotating shaft of the rotating portion 1121. The direction of the abutting surface 1111 is opposite to the direction of the notch of the clamping groove 11231.

[0053] In some embodiments, the elastic member 113 is a cylindrical compression spring. It should be noted that a compression spring refers to a spring that can store elastic energy during compression. Figure 4 The elastic member connecting portion 1122 is provided with a protruding column 11221, and the protruding direction of the protruding column 11221 is the same as the direction of the notch of the clamping groove 11231. Figure 2 and Figure 3 One end of the cylindrical compression spring is sleeved outside the protruding column 11221 and abuts against the elastic member connecting portion 1122 , and the other end of the cylindrical compression spring abuts against the base 111 .

[0054] In some embodiments, the elastic member connecting portion 1122 is provided with a plurality of protruding columns 11221, and the spacings between the plurality of protruding columns 11221 and the rotating shaft of the rotating portion 1121 are not equal. Exemplarily, the plurality of protruding columns 11221 are arranged at intervals along the direction from the rotating portion 1121 toward the elastic member connecting portion 1122. Further, the cylindrical compression spring is selectively sleeved outside one of the protruding columns 11221 and abuts against the elastic member connecting portion 1122. In this way, the force of the cylindrical compression spring acting on the clamping portion 1123 can be adjusted by adjusting the connection position of the cylindrical compression spring.

[0055] refer to Figure 4 In some embodiments, the rotating portion 1121 is provided with a through hole 11211. The base 111 is provided with a mounting hole 1112. Figure 2 The rotating part 1121 is connected to the base 111 through a connecting member 130 that is provided in the through hole 11211 and connected to the hole wall of the mounting hole 1112. Exemplarily, the connecting member 130 is a threaded fastener. For example, the connecting member 130 is a bolt or a screw. Specifically, the connecting member 130 can be a screw with a washer.

[0056] It should be noted that although the drawings provided in the embodiments of the present application mainly show the case where the rotating portion 1121 is located between the elastic member connecting portion 1122 and the clamping portion 1123, it is understandable that the rotating portion 1121 may not be located between the elastic member connecting portion 1122 and the clamping portion 1123. Figure 2 The rotating part 1121 may be located at the top of the rotating body 112, the elastic member connecting part 1122 is located at the bottom of the rotating body 112, and the clamping part 1123 is located between the top and the bottom of the rotating body 112. The lock inserting part of the lock body 110 is opened at a position opposite to the clamping part 1123.

[0057] Exemplarily, the elastic member 113 is a tension spring. The tension spring refers to a spring that can store elastic energy during the stretching process. The elastic member 113 is disposed on the right side of the rotating body 112, and the elastic member 113 is respectively connected to the elastic member connecting portion 1122 and the base 111.

[0058] Exemplarily, the elastic member 113 is a compression spring. The compression spring refers to a spring that can store elastic energy during compression. The elastic member 113 is disposed on the left side of the rotating body 112, and the elastic member 113 is respectively connected to the elastic member connecting portion 1122 and the base 111.

[0059] The present application embodiment provides a door assembly. Figures 9 to 13 The door assembly 10 provided in the embodiment of the present application includes: any one of the locks 100 provided in the embodiment of the present application.

[0060] In some embodiments, the door assembly 10 further includes a door body 200 and a frame 300. The door body 200 is rotatably connected to the frame 300. Exemplarily, the door body 200 can be rotatably connected to the frame 300 via a hinge.

[0061] In some embodiments, the base 111 is provided on the door body 200. Exemplarily, the base 111 is integrally formed on the door body 200. Alternatively, a mounting portion may be provided on the door body 200, and the portion where the mounting portion is located may be regarded as the base 111 of the lock body 110.

[0062] Of course, in other embodiments, the base 111 includes a housing, and the rotating body 112 and the elastic member 113 can be installed on the housing; further, the housing can be installed on the door body 200. In addition, one side of the housing is open to facilitate the installation of the rotating body 112 and the elastic member 113 on the housing. Further, the base 111 also includes a cover. The cover can cover the open side of the housing.

[0063] In some embodiments, the lock catch 120 is disposed on the frame 300. When the door body 200 is in a closed state, the lock catch 120 is inserted into the lock body 110. For example, the frame 300 is provided with a convex rib, and the lock catch 120 can be disposed on the convex rib. The frame 300 is provided with a door opening, and when the door body 200 is in a closed state, the door body 200 blocks the door opening.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
