Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a wind-resistant frame splicing structure, a wind-resistant frame assembly, and a display device. Background Art

[0002] In order to increase the placement stability of the display screen, a wind-resistant frame is generally provided on the back of the display screen. In addition, according to the requirements of the actual display area, multiple display screens need to be spliced vertically. Correspondingly, the wind-resistant frames for supporting adjacent display screens need to be spliced. Currently, most adjacent wind-resistant frames are inserted up and down and locked by a threaded fit, but when splicing, the two wind-resistant frames need to be rotated relative to each other. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a wind-resistant frame splicing structure, a wind-resistant frame assembly, and a display device to solve the technical problem in the prior art that two wind-resistant frames need to be rotated relative to each other to achieve splicing.

[0004] To achieve the above purpose, the technical solution adopted in this application is: In the first aspect, a wind-resistant frame splicing structure is provided for realizing the splicing of wind-resistant frames. The wind-resistant frame splicing structure includes an upper lock seat, a lock tongue, and a lower lock seat; the upper lock seat and the lower lock seat are arranged to be installed at two ends of the wind-resistant frame; the lock tongue is installed on the upper lock seat, the lower lock seat has a lock hole, and the lock tongue can be inserted into the lock hole of the adjacent wind-resistant frame under the action of an external force.

[0005] By providing a lock tongue on the upper lock seat and a lock hole in the lower lock seat, the lock tongue can be locked into the lock hole under the action of an external force, so that when splicing the wind-resistant frames, only the lock tongue needs to be driven to slide by an external force, without rotating the entire wind-resistant frame, and the operation is simple.

[0006] In one embodiment, the lock tongue can be retracted from the lock hole into the upper lock seat under the action of an external force.

[0007] By retracting the lock tongue from the lock hole, the spliced wind-resistant frames can be disassembled from each other, which is convenient for the handling of the wind-resistant frames.

[0008] In one embodiment, the wind-resistant frame splicing structure further includes a limiting component, and the limiting component can lock the lock tongue in the lock hole.

[0009] Through the setting of the limiting component, the lock tongue can be locked in the lock hole, thereby ensuring the locking reliability of the upper lock seat and the lower lock seat, and further ensuring the splicing reliability between adjacent wind-resistant frames.

[0010] In one embodiment, the limiting assembly includes a limiting member slidably disposed on the lower lock base; the limiting member can be engaged with the lock tongue at a first position; the limiting member can avoid the lock tongue at a second position so that the lock tongue can be inserted into or withdrawn from the lock hole.

[0011] The engagement and avoidance of the lock tongue by the limiting member are achieved by the sliding of the limiting member, that is, the limiting member can have a large range of movement, so that the limiting member can be inserted into the lock tongue to a greater depth to ensure the locking reliability.

[0012] In one embodiment, the limiting assembly further includes an elastic member abutted between the limiting member and the lower lock base, and the elastic member is used to hold the limiting member at the first position.

[0013] By providing the elastic member, not only can the limiting member be held at the first position to ensure the reliable engagement between the limiting member and the lock tongue, but also the reset of the limiting member can be realized, making the reset of the limiting member labor-saving.

[0014] In one embodiment, the limiting member has a limiting groove, and the lock tongue includes a penetrating portion and a stopping portion connected to each other, and the outer diameter of the stopping portion is larger than that of the penetrating portion; when the limiting member is at the second position, the stopping portion can pass through the limiting groove; when the limiting member is at the first position, the stopping portion stops at the limiting surface of the limiting member facing away from the upper lock base.

[0015] Among them, the setting of the limiting groove enables the whole limiting member to straddle the lock hole, that is, the limiting member can extend from one side of the lock hole to the other side of the lock hole, so that the part of the limiting member on one side of the lock hole abuts against the elastic member, and the part of the limiting member on the other side of the lock hole can extend out of the lower lock base for the user to drive, making the structural position layout of the limiting member and the elastic member reasonable and the operation convenient. In addition, by including a penetrating portion and a stopping portion in the lock tongue, the stopping portion can be limited to the limiting surface in the locked state.

[0016] In one embodiment, the upper lock base is provided with a locking mechanism connected to the lock tongue, and the locking mechanism is used to provide a locking force for the lock tongue so that the stopping portion of the lock tongue abuts tightly against the limiting surface of the limiting member.

[0017] Among them, the setting of the locking mechanism enables the lock tongue to abut tightly against the limiting member in the locked state, ensuring the locking reliability between the lower lock base and the upper lock base, and further ensuring the locking reliability between the two wind-resistant frames.

[0018] In one embodiment, the locking mechanism includes a screw rod and a locking block. The locking block is threadedly sleeved on the screw rod, and the locking block abuts against the locking tongue. Rotating the screw rod can drive the locking block to slide, so as to drive the locking tongue to slide and make the stopping portion abut tightly against the limiting surface.

[0019] Among them, the locking force for the locking tongue is realized through the threaded fit between the screw rod and the locking block. It can not only finely adjust the locking force of the locking tongue, will not push the locking tongue to produce a large displacement, and has a large locking force and is firmly locked.

[0020] In one embodiment, the locking block has a first wedge surface, and the locking tongue has a second wedge surface. The first wedge surface is in fit with the second wedge surface. Rotating the screw rod can drive the locking block to move in a first direction, so as to push the locking tongue to slide in a second direction. The first direction is perpendicular to the second direction, and the first wedge surface is inclined relative to the first direction.

[0021] Among them, the locking block and the locking tongue are arranged in fit through the first wedge surface and the second wedge surface, and both the first wedge surface and the second wedge surface are inclined relative to the first direction and the second direction. Thus, when the locking block slides in the first direction, it has a pushing force on the locking tongue in the second direction, and then pushes the locking tongue to slide in the second direction. In this way, the locking block and the locking tongue slide in two mutually perpendicular directions, and their movements will not interfere with each other and will not affect each other.

[0022] In one embodiment, a lock piece assembly is provided in the lower lock seat. The lock piece assembly includes a first lock piece and a second lock piece fixedly connected. A sliding cavity is formed between the first lock piece and the second lock piece, and the limiting member is slidably arranged in the sliding cavity. The lock hole penetrates through the first lock piece and the second lock piece.

[0023] By slidably arranging the limiting member between the first lock piece and the second lock piece, the limiting member, the first lock piece and the second lock piece are combined to form a lock buckle module, and the lock hole is formed on the first lock piece and the second lock piece. The above setting makes it unnecessary to form a lock hole and a sliding cavity in the lower lock seat, thereby simplifying the structure of the lower lock seat, reducing the design cost of the lower lock seat, and at the same time, the lock buckle module can be disassembled, assembled and maintained as a whole, and integrally processed and designed, reducing the assembly cost.

[0024] In one embodiment, the upper lock seat has an installation cavity with an opening facing the lower lock seat, and the locking tongue is arranged in the installation cavity. A limiting hole communicating with the installation cavity is formed in the side wall of the upper lock seat. The locking tongue is connected with a handle, and the handle extends outwards through the limiting hole, and the handle is slidably limited in the limiting hole.

[0025] Among them, through the setting of the handle, the user can drive the lock tongue to slide by pushing the handle on the outside of the upper lock seat, so that the lock tongue can be inserted into the lock hole or withdrawn from the lock hole; at the same time, through the setting of the limiting hole, it can limit the sliding stroke of the handle, thereby limiting the sliding stroke of the lock tongue and preventing the lock tongue from falling out of the installation cavity.

[0026] In a second aspect, the present application further provides a wind-resistant frame assembly, including a wind-resistant frame and the above-mentioned wind-resistant frame splicing structure, wherein an upper locking seat and a lower locking seat are respectively installed at opposite ends of the wind-resistant frame.

[0027] Through the design of the wind-resistant frame splicing structure, when the wind-resistant frame assembly is spliced, it is only necessary to insert the lock tongue into the lock hole without rotating the wind-resistant frame.

[0028] In a third aspect, the present application also provides a display device, comprising a display screen and the above-mentioned wind-resistant frame assembly, wherein the wind-resistant frame assembly is supported on the back side of the display screen.

[0029] The beneficial effect of the display device provided by the present application is that the splicing operation of the display device is simple through the provision of the above-mentioned wind-resistant frame assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0044] In order to increase the placement stability of the display screen, a wind-resistant frame is generally provided on the back of the display screen. In addition, according to the requirements of the actual display area, a plurality of display screens need to be spliced in the vertical direction. Correspondingly, the wind-resistant frames for supporting adjacent display screens need to be spliced. Currently, most adjacent wind-resistant frames are inserted vertically and locked by means of threaded cooperation. When splicing, the two wind-resistant frames need to be rotated relative to each other, which is inconvenient to operate.

[0045] In view of this, the embodiments of this application provide a wind-resistant frame splicing structure, a wind-resistant frame assembly and a display device, so that the splicing of the wind-resistant frames only requires inserting the locking tongue into the locking hole, without rotating the two wind-resistant frames relative to each other.

[0046] Please refer to Figure 1 , the embodiments of this application provide a display device, including a display screen 3 and a wind-resistant frame assembly. The wind-resistant frame assembly is used to support the back of the display screen 3 to improve the support stability of the display screen 3.

[0047] The embodiments of this application also provide a wind-resistant frame assembly. The wind-resistant frame assembly includes a wind-resistant frame 2 and a wind-resistant frame splicing structure 1. The wind-resistant frame splicing structure 1 is used to realize the splicing of adjacent wind-resistant frames 2, so that each wind-resistant frame 2 is spliced into a whole to improve the support strength and support stability of each wind-resistant frame 2 for the display screen 3.

[0048] Please refer to Figures 1 to 5 , now the wind-resistant frame splicing structure 1 provided by the embodiments of this application will be described. The wind-resistant frame splicing structure 1 is used for splicing two adjacent wind-resistant frames 2.

[0049] The wind-resistant frame splicing structure 1 includes an upper locking seat 100, a locking tongue 200 and a lower locking seat 300; the upper locking seat 100 and the lower locking seat 300 are arranged to be installed at two ends of the wind-resistant frame 2; the locking tongue 200 is installed on the upper locking seat 100, and the lower locking seat 300 has a locking hole 530. The locking tongue 200 can be inserted into the locking hole 530 of the adjacent wind-resistant frame 2 under the action of an external force.

[0050] Among them, the locking tongue 200 can be inserted into the locking hole 530 under the action of an external force. Here, the external force can be manual driving force or electric driving force. In addition, the locking tongue 200 can be directly manually driven, or the external force can be transmitted to the locking tongue 200 through other structures.

[0051] When splicing the wind-resistant frame 2, the two ends of two adjacent wind-resistant frames 2 respectively having the upper lock seat 100 and the lower lock seat 300 are relatively close to each other. By applying an external force, the locking tongue 200 of the upper lock seat 100 of one of the wind-resistant frames 2 is slid and locked into the locking hole 530 of the lower lock seat 300 of the adjacent wind-resistant frame 2, thereby realizing the splicing of two adjacent wind-resistant frames 2.

[0052] In the wind-resistant frame splicing structure 1 in the embodiment of the present application, by providing the locking tongue 200 on the upper lock seat 100 and the locking hole 530 in the lower lock seat 300, the locking tongue 200 can be locked into the locking hole 530 of the adjacent wind-resistant frame 2 under the action of an external force. When splicing the wind-resistant frame 2, only by driving the locking tongue 200 to slide by an external force, there is no need to rotate the entire wind-resistant frame 2, and the operation is simple.

[0053] In one embodiment, the locking tongue 200 can be retracted from the locking hole 530 into the upper lock seat 100 under the action of an external force. That is, in a scenario where it is not necessary to splice the wind-resistant frames 2 together, the locking tongue 200 can be retracted from the locking hole 530 into the upper lock seat 100 by an external force, which is convenient for the handling of the wind-resistant frame 2 and also convenient for the disassembly, maintenance and replacement of the wind-resistant frame splicing structure 1.

[0054] In one embodiment, please refer to Figure 6 , the wind-resistant frame splicing structure 1 further includes a limiting component 400, and the limiting component 400 can lock the locking tongue 200 in the locking hole 530.

[0055] When splicing the wind-resistant frame 2, the locking tongue 200 is slid and locked into the locking hole 530 by an external force, and the locking tongue 200 is locked in the locking hole 530 by the limiting component 400. Through the setting of the limiting component 400, the locking tongue 200 can be locked in the locking hole 530, thereby ensuring the locking reliability of the upper lock seat 100 and the lower lock seat 300, and further ensuring the splicing reliability between adjacent wind-resistant frames 2.

[0056] In one embodiment, please refer to Figures 4 to 6 , the limiting component 400 includes a limiting member 410, the limiting member 410 is slidably arranged on the lower lock seat 300 and has a first position and a second position; when the limiting member 410 is in the first position, it can be engaged with the locking tongue 200; when the limiting member 410 is in the second position, it can avoid the locking tongue 200 so that the locking tongue 200 can be inserted into or withdrawn from the locking hole 530.

[0057] Specifically, in the initial state, the limiter 410 is in the first position. When splicing is required, the limiter 410 is slid to make the limiter 410 slide from the first position to the second position, so that the limiter 410 avoids the lock tongue 200; then, the user can slide the lock tongue 200 to lock the lock tongue 200 into the lock hole 530; then, the limiter 410 is driven to reset from the second position to the first position, so that the limiter 410 is engaged with the lock tongue 200, thereby locking the lock tongue 200 in the lock hole 530, ensuring the locking reliability of the upper lock seat 100 and the lower lock seat 300. In this embodiment, the limiter 410 can be engaged with and avoid the lock tongue 200 by sliding, that is, the limiter 410 can have a larger movement, so that the limiter 410 can be engaged with the lock tongue 200 to a greater depth, so as to ensure the locking reliability. It can be understood that in other embodiments of the present application, a glass bead screw can be installed on the inner wall surface of the lock hole 530, and an arc groove can be provided on the outer wall of the lock tongue 200, and the glass bead screw can be inserted into the arc groove to lock the lock tongue 200 in the lock hole 530. This is not a sole limitation here.

[0058] See also Figure 4 and Figure 5 The limiter 410 slides along the first direction X, and the lock tongue 200 slides along the second direction Y, and the first direction X and the second direction Y are perpendicular to each other. The sliding of the limiter 410 can avoid or clamp the lock tongue 200. When the windproof frame 2 is placed vertically, the first direction X is the horizontal direction, and the second direction Y is the vertical direction.

[0059] In one embodiment, see Figure 6 The limit assembly 400 further includes an elastic member 420, which is in contact between the limit member 410 and the lower lock seat 300, and is used to keep the limit member 410 in the first position. In the initial state, the elastic member 420 is in a naturally stretched state, the limit member 410 is in the first position, the limit member 410 blocks the lock tongue 200, and the lock tongue 200 cannot be inserted into the lock hole 530. When splicing is required, the user overcomes the elastic force of the elastic member 420 and manually pushes the limit member 410 so that the limit member 410 avoids the lock tongue 200. At this time, the elastic member 420 is compressed and accumulates elastic force; then, the user can slide the lock tongue 200 to lock the lock tongue 200 into the lock hole 530, and the user can release the limit member 410 at the same time. The limit member 410 is reset to the first position under the elastic force of the elastic member 420 and engages the lock tongue 200, that is, the lock tongue 200 is locked in the lock hole 530, thereby ensuring the locking reliability of the upper lock seat 100 and the lower lock seat 300.

[0060] In this embodiment, the elastic member 420 is used to reset the limiting member 410, which can ensure the firmness of the engagement between the limiting member 410 and the locking tongue 200, and make it labor-saving to reset the limiting member 410.

[0061] In one embodiment, please refer to Figure 5 and Figure 6 A sliding cavity 540 is formed in the lower lock base 300. At least a part of the limiting member 410 is slidably disposed in the sliding cavity 540, and the elastic member 420 is installed in the sliding cavity 540. The sliding cavity 540 has a first inner wall 541 and a second inner wall 542 which are oppositely arranged. The limiting member 410 is slidably stopped between the first inner wall 541 and the second inner wall 542 of the sliding cavity 540. Thus, the sliding stroke of the limiting member 410 can be limited by the first inner wall 541 and the second inner wall 542.

[0062] Optionally, the elastic member 420 is a cylindrical spring, and the elastic member 420 abuts between the limiting member 410 and the first inner wall 541 of the sliding cavity 540. In addition, the number of the elastic members 420 is two, and the two elastic members 420 respectively abut on the opposite sides of the limiting member 410 to ensure the smooth sliding of the limiting member 410. It can be understood that in other embodiments of the present application, the elastic member 420 can also be a spring sheet, and the number of the elastic members 420 can also be one, three or more than three, which is not uniquely limited here.

[0063] In one embodiment, please refer to Figure 5 and Figure 6 The limiting member 410 has a limiting groove 411. The locking tongue 200 includes a penetrating portion 210 and a stopping portion 220 which are connected to each other. The outer diameter of the stopping portion 220 is larger than that of the penetrating portion 210. When the limiting member 410 is in the second position, the stopping portion 220 can pass through the limiting groove 411. When the limiting member 410 is in the first position, the stopping portion 220 is limited by the limiting surface 412 of the limiting member 410 facing away from the upper lock base 100. Among them, the setting of the limiting groove 411 enables the whole limiting member 410 to straddle the lock hole 530, that is, enables the limiting member 410 to extend from one side of the lock hole 530 to the other side of the lock hole 530. Furthermore, a part of the limiting member 410 located on one side of the lock hole 530 abuts against the elastic member 420, and a part of the limiting member 410 located on the other side of the lock hole 530 can extend out of the lower lock base 300 for the user to drive, so that the structural position layout of the limiting member 410 and the elastic member 420 is reasonable and the operation is convenient. In addition, by including the penetrating portion 210 and the stopping portion 220 in the locking tongue 200, the stopping portion 220 can be limited by the limiting surface 412 in the locked state.

[0064] Specifically, please refer to Figure 5 and Figure 6, the limiting member 410 includes a limiting portion 413 and a driving portion 414. The limiting portion 413 is slidably disposed in the upper locking seat 100. The limiting groove 411 is formed in the limiting portion 413. The driving portion 414 is connected to the limiting portion 413. The driving portion 414 extends to the outside of the upper locking seat 100 for the user to drive. The elastic member 420 abuts between the side of the limiting portion 413 away from the driving portion 414 and the upper locking seat 100.

[0065] In one embodiment, please refer to Figure 5 and Figure 6 , the limiting portion 413 is plate-shaped, and the limiting groove 411 penetrates along the sliding direction of the locking tongue 200 (the second direction Y). The limiting groove 411 includes a small-diameter portion 4112 and a large-diameter portion 4111 that communicate with each other. The inner diameter of the large-diameter portion 4111 is greater than the outer diameter of the stop portion 220. The inner diameter of the small-diameter portion 4112 is smaller than the outer diameter of the stop portion 220, and the inner diameter of the small-diameter portion 4112 is greater than the outer diameter of the penetrating portion 210. When the limiting member 410 is in the first position, the small-diameter portion 4112 corresponds to the position of the stop portion 220, so that the locking tongue 200 cannot pass through the limiting groove 411 and be locked into the lock hole 530. When the limiting member 410 is in the second position, the large-diameter portion 4111 corresponds to the position of the stop portion 220, so that the stop portion 220 can be inserted into the lock hole 530 through the large-diameter portion 4111. When the limiting member 410 is reset from the second position to the first position, the penetrating portion 210 slides into the small-diameter portion 4112, so that the stop portion 220 is stopped at the limiting surface 412.

[0066] In one embodiment, please refer to Figure 4 and Figure 5 , the locking tongue 200 includes a lock body portion 230 and a tongue body portion. The lock body portion 230 is slidably disposed in the upper locking seat 100. The tongue body portion extends from one end of the lock body portion 230. The tongue body portion includes a penetrating portion 210 and a stop portion 220 that are connected to each other. Specifically, an annular groove 240 is recessed in the outer peripheral wall of the tongue body portion to form the penetrating portion 210 and the stop portion 220.

[0067] In one embodiment, please refer to Figure 6 and Figure 7 , the upper locking seat 100 is provided with a locking mechanism 700. The locking mechanism 700 is connected to the locking tongue 200. The locking mechanism 700 is used to provide a locking force for the locking tongue 200, so that the stop portion 220 abuts tightly against the limiting surface 412 of the limiting member 410. Among them, the setting of the locking mechanism 700 enables the locking tongue 200 to abut tightly against the limiting member 410 in the locked state, ensuring the locking reliability between the lower locking seat 300 and the upper locking seat 100, and further ensuring the locking reliability between the two wind-resistant frames 2.

[0068] In one embodiment, please refer to Figure 4, the locking mechanism 700 includes a screw 710 and a locking block 720. The locking block 720 is threadedly sleeved on the screw 710, and the locking block 720 abuts against the lock tongue 200. Rotating the screw 710 can drive the locking block 720 to slide, so as to drive the lock tongue 200 to slide and make the stopping portion 220 abut tightly against the limiting surface 412. Among them, the locking force for the lock tongue 200 is provided through the threaded fit between the screw 710 and the locking block 720. It can not only finely adjust the locking force of the lock tongue 200, will not push the lock tongue 200 to have a large displacement, and has a large locking force and is firmly locked.

[0069] In one embodiment, please refer to Figure 4 , the locking block 720 has a first wedge surface 721, and the lock tongue 200 has a second wedge surface 250. The first wedge surface 721 and the second wedge surface 250 are in abutting contact. Rotating the screw 710 can drive the locking block 720 to move along the first direction X, so as to push the lock tongue 200 to slide along the second direction Y, so that the stopping portion 220 abuts tightly against the limiting surface 412. Among them, the first direction X is perpendicular to the second direction Y. The first wedge surface 721 is inclined with respect to the first direction X and the second direction Y, and the second wedge surface 250 is inclined with respect to the first direction X and the second direction Y.

[0070] In this embodiment, since the locking block 720 and the lock tongue 200 are arranged in abutting contact through the first wedge surface 721 and the second wedge surface 250, and both the first wedge surface 721 and the second wedge surface 250 are inclined with respect to the first direction X and the second direction Y, when the locking block 720 slides along the first direction X, it has a driving force on the lock tongue 200 along the second direction Y, and then pushes the lock tongue 200 to slide along the second direction Y. In this way, the locking block 720 and the lock tongue 200 slide along two mutually perpendicular directions, and their movements will not interfere with each other and will not affect each other.

[0071] In one embodiment, please refer to Figure 4 and Figure 5 , the lock tongue 200 is formed with a through groove 260, the locking block 720 is arranged in the through groove 260, and the second wedge surface 250 is the inner bottom surface of the through groove 260. Rotating the screw 710 can drive the locking block 720 to move along the first direction X, so as to push the lock tongue 200 to slide along the second direction Y. Among them, the setting of the through groove 260 can accommodate the locking block 720 in the through groove 260, and the screw 710 horizontally penetrates through the through groove 260, which not only makes the locking block 720 and the lock tongue 200 able to abut stably, but also reduces the occupied space of the locking block 720.

[0072] In one embodiment, please refer to Figure 4, one end of the screw rod 710 extends out of the upper lock seat 100. A knob 730 is installed at the end of the screw rod 710 that extends out of the upper lock seat 100. The knob 730 is fixed to the screw rod 710 by screws. Rotating the knob 730 drives the screw rod 710 to rotate.

The limiting member 410 is slidably disposed in the sliding cavity 540; the lock hole 530 penetrates through the first lock piece 510 and the second lock piece 520. In this embodiment, by slidably disposing the limiting member 410 between the first lock piece 510 and the second lock piece 520, the limiting member 410, the first lock piece 510, and the second lock piece 520 are combined to form a lock module, and the lock hole 530 is formed on the first lock piece 510 and the second lock piece 520. The above settings enable the lock hole 530 not to be formed in the lower lock seat 300 and the sliding cavity 540 not to be formed in the lower lock seat 300, thereby simplifying the structure of the lower lock seat 300, reducing the design cost of the lower lock seat 300, and at the same time enabling the overall disassembly, assembly, and maintenance of the lock module, as well as the overall processing and design, reducing the assembly cost.

[0074] Specifically, please refer to Figure 4 and Figure 5 , the first lock piece 510 and the second lock piece 520 are overlapped with each other and locked by fasteners. A groove is recessed on one side of the first lock piece 510 facing the second lock piece 520. The second lock piece 520 covers the opening of the groove so that the first lock piece 510 and the second lock piece 520 jointly enclose to form the sliding cavity 540. In other embodiments of the present application, the above groove may also be formed on one side of the second lock piece 520 facing the first lock piece 510; or, grooves are formed on both the first lock piece 510 and the second lock piece 520, and the grooves on the first lock piece 510 and the grooves on the second lock piece 520 jointly form the sliding cavity 540.

Among them, through the arrangement of the handle 600, the user can drive the lock tongue 200 to slide by pushing the handle 600 outside the upper lock seat 100, so that the lock tongue 200 can be inserted into or withdrawn from the lock hole 530; at the same time, through the arrangement of the limiting hole 120, it can limit the sliding stroke of the handle 600, thereby being able to limit the sliding stroke of the lock tongue 200 and prevent the lock tongue 200 from disengaging from the installation cavity 110.

[0079] Specifically, before splicing, the bottom of the lock tongue 200 is supported on the bottom wall of the installation cavity 110, so as to ensure the installation stability of the lock tongue 200 in the upper lock seat 100; during splicing, the handle 600 is slid towards the lower lock seat 300 until the handle 600 abuts against the inner wall of one end of the limiting hole 120. At this time, the lock tongue 200 can just be locked into the lock hole 530.

[0080] In one embodiment, please refer to Figure 5 , the handle 600 is locked and fixed on the lock tongue 200 by screws, so that the handle 600 and the lock tongue 200 can move synchronously.
