Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door locks, in particular to a door lock mechanism that can be assembled through a set of locks without distinguishing between left and right sides. BACKGROUND

[0002] Currently, fingerprint lock products on the market need to be installed according to the left and right directions of the door panel, which are divided into left and right door opening lock types, resulting in the need to produce different door lock models corresponding to different left and right directions. This requires a large number of different models to be stocked, which brings huge cost to production and sales. Moreover, this door lock structure that needs to distinguish between left and right sides is also prone to being mistaken, which leads to the inability to install in time and brings many inconveniences to users. In particular, when the clamping plate clamped with the door panel has a structure with one side open and the other side closed, if it is clamped to one side of the door panel, it is suitable, but if it is clamped to the other side of the door panel, the clamping plate needs to be inverted as a whole, so that the structures connected to it need to be inverted and cannot be normally unlocked. For example, the application number CN201721840508.8 discloses a new type of inside and outside mechanical and electrical integrated opening and closing lock mechanism suitable for glass door locks. The C-shaped clamping plate used in this mechanism can only adapt to one side of the glass door panel, and needs to distinguish between left and right door panels for installation. If it is installed on the other side of the door panel, all the connected structures on it will be completely inverted, and the normal unlocking function cannot be realized. Therefore, it cannot achieve the effect of adapting to both left and right door panels. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to solve the above problems in the prior art and provides a door lock mechanism that does not need to distinguish between left and right lock body models and makes the installation of left and right door types simpler.

[0004] To solve the above technical problems, the technical scheme adopted by the present application is as follows: a door lock mechanism, the structure of which includes a front lock body, a rear lock body and a clamping plate. The clamping plate includes a front clamping plate, a rear clamping plate and a side clamping plate located between the front clamping plate and the rear clamping plate. The front clamping plate, the rear clamping plate and the side clamping plate form a receiving groove for inserting the door panel. The front clamping plate and the rear clamping plate are both provided with upper and lower symmetrical connecting pieces. The connecting pieces are used to connect the corresponding front lock body and rear lock body.

[0005] With the above structure, since the connecting pieces are symmetrically arranged on the clamping plate, when the clamping plate is connected with the corresponding front lock body and rear lock body, no matter whether the clamping plate is placed upright or upside down, the connecting pieces on the clamping plate can be connected with the corresponding front lock body and rear lock body. Therefore, when installed with one side door plate, the clamping plate can be matched with the corresponding lock body, and when installed with the other side door plate, the clamping plate is rotated by 180 degrees and placed upside down. Since the connecting pieces are symmetrically arranged, the clamping plate can still be matched with the corresponding lock body, and the lock body does not need to be placed upside down. Therefore, the door lock does not need to distinguish between left and right types, and one set of lock body can be assembled with left or right door plate, and does not affect the normal use of the lock body, and does not need to prepare multiple types, which does not cause trouble to the user and is simple and convenient to assemble.

[0006] Further, the connecting piece includes a hook symmetrically arranged on the front clamping plate along the length direction, and the front lock body is provided with a hook groove for hooking with the hook. With this structure, the front clamping plate and the front lock body are connected by hooking between the hook and the hook groove. Moreover, no matter whether the front clamping plate is placed upright or upside down, the hook symmetrically arranged on the front clamping plate can be connected with the hook groove on the front lock body, so that the door plate on different sides can be clamped and installed without the need to distinguish between different types.

[0007] Further, the hook is arranged in two groups along the up-down direction of the front clamping plate, each group containing two hooks, and the hooks in each group are symmetrically arranged at the positions close to the both ends in the width direction of the front clamping plate. With this structure, the hook groove arranged along the length direction of the front lock body can be more tightly connected, the connection points are increased, and the connection is more stable.

[0008] Further, the hook includes a first extension wall extending outwardly and perpendicularly to the body of the front clamping plate, and a second extension wall extending perpendicularly to the end face of the first extension wall. With the above structure, the hook and the hook groove are effectively hooked by the specific hook structure, and the thickness direction does not shake or shift.

[0009] Further, the inner wall of the front lock body is provided with a baffle abutting against the second extension wall, and the baffle and the inner wall of the front lock body form a hook groove. With this arrangement, the hook and the hook groove can be effectively hooked, and the second extension wall at the front end of the hook abuts against the inner wall of the baffle, achieving close and connected fitting.

[0010] Further, the hook groove is arranged on one end of the front lock body in the length direction; by using the structure, as long as the one end of the front lock body is provided with the hook groove corresponding to the hook, the connection between the front clamping plate and the front lock body can be realized; and during assembly, as only one end is provided with the hook groove, the assembly is more convenient, and the situation that the second extension wall of the hook is blocked by the baffle of the hook groove and cannot be hooked cannot occur.

[0011] Further, the connecting piece further comprises a connecting plate arranged on the front clamping plate in a symmetrical manner along the length direction, which extends towards the front lock body, and the connecting plate is provided with a first connecting hole; correspondingly, the front lock body is provided with a second connecting hole, and the first connecting hole and the second connecting hole are connected by a screw; by using the above structure, after the hook and the hook groove are hooked, the further connection between the front clamping plate and the front lock body is realized through the connecting holes, so that the shaking between the two is avoided, and fixed assembly is realized.

[0012] Further, the second extension wall extends towards the direction of the two ends of the length direction of the front clamping plate; specifically, the second extension wall located at the upper end of the front clamping plate extends upwards, and the second extension wall located at the lower end of the front clamping plate extends downwards, and the extension direction can realize stable hooking with the hook groove and is not easy to be unhooked.

[0013] Further, the second connecting hole is located on the side wall of one end of the length direction of the front lock body, and the second connecting hole is arranged opposite to the hook groove; that is, the second connecting hole is located on the side wall of the one end of the thickness extension of the upper and lower two ends of the front lock body, and the first connecting hole and the hook groove are arranged opposite to each other, that is, they are located on the upper and lower two ends respectively and not on the same end; and the second connecting hole is aligned with the first connecting hole on the connecting plate, and the two are fastened by screwing; in this way, one end of the front lock body and the front clamping plate is connected by hooking, and the other end is fastened by a screw, so that the connection is more tight and firm.

[0014] Further, the connecting piece on the rear clamping plate is a first mounting hole arranged in a symmetrical manner along the length direction, and correspondingly, the rear lock body is provided with a second mounting hole, and the first mounting hole and the second mounting hole are connected by a screw; by using the structure, through the upper and lower symmetrical mounting holes, the rear clamping plate can be connected with the rear lock body regardless of whether it is placed vertically or upside down, so that it is not limited by the orientation of the left and right door plates, and one set of lock can meet the assembly of door plates in different orientations.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] As attached Figures 1-8 As shown, this application discloses a door lock mechanism. The mechanism includes a front lock body 1, a rear lock body 2, and a clamping plate 3. The clamping plate 3 includes a front clamping plate 301, a rear clamping plate 302, and a side clamping plate 303 located between the front clamping plate 301 and the rear clamping plate 302. The front clamping plate 301, the rear clamping plate 302, and the side clamping plate 303 form a receiving groove 4 for inserting a door panel. The front clamping plate 301 and the rear clamping plate 302 are each provided with symmetrically arranged connecting members 5. Used for connection with the corresponding front lock body 1 and rear lock body 2; specifically, the front clamping plate and the rear clamping plate of this application are respectively used to connect with the outer surface and inner surface of the door panel, and the side clamping plate extends along the thickness direction of the door panel; the front clamping plate, the rear clamping plate and the side clamping plate are connected in sequence to form a receiving groove, the receiving groove has an opening on the upper, lower and one long side, and the other long side is provided with an opening frame structure of the side clamping plate; wherein the front clamping plate is connected to the front lock body, the rear clamping plate is connected to the rear lock body, and the side clamping plate abuts against the side wall of the door panel in the thickness direction.

[0027] With the above structure, the clamping plate has symmetrically arranged upper and lower connectors. Therefore, when the clamping plate is connected to the corresponding front and rear lock bodies, whether it is placed upright or upside down, the connection between the connectors and the corresponding lock bodies remains unaffected. Thus, when installed on one side of a door panel, the clamping plate can fit the corresponding lock body. When installed on the other side of a door panel, even if the clamping plate is rotated 180 degrees and inverted, the symmetrical structure of the connectors still allows it to fit the corresponding lock body; it is not necessary to invert the lock body, only the clamping plate needs to be inverted. For details, please refer to the appendix. Figure 8As shown in the drawings, the left side is the assembly position of the clamping plate and the left door plate, and the right side is the assembly position of the clamping plate and the right door plate. The clamping plate is placed in the normal position, and the structure schematic view of the clamping plate is placed in the inverted position. From the drawings, it can be seen that the connecting piece on the clamping plate is symmetrical whether it is on the left side or the right side, so it does not affect the connection with the lock body. Therefore, the door lock of this structure does not need to distinguish between left and right models. A set of lock can be assembled whether it is a left door plate or a right door plate, and does not affect the normal use of the lock body, does not cause trouble to the user, and is simple and convenient to assemble.

[0028] As shown in the drawings, Figure 3 , 5 The connecting piece 5 described in the application includes a hook 501 symmetrically arranged on the front clamping plate 301 in the length direction, and the front lock body 1 is provided with a hook groove 101 for hooking with the hook 501. With this structure, the front clamping plate and the front lock body are connected by hooking between the hook and the hook groove. Moreover, whether the front clamping plate is placed normally or inverted, because the hooks are symmetrically arranged on the top and bottom, the front clamping plate can be connected with the hook groove on the front lock body, thereby realizing clamping and installation of different side door plates without the need for different models.

[0029] As shown in the drawings, Figure 3 , 5 The hook 501 described in the application is symmetrically arranged on the front clamping plate 1 in each group, i.e. the upper and lower two groups are symmetrically arranged along the length extension direction of the front clamping plate. Each group contains two hooks, and the hooks 501 in each group are symmetrically arranged at the positions close to both ends in the width direction of the front clamping plate 1. With this structure, the hook groove arranged in the length direction of the front lock body can realize more close connection, increase the connection point, and make the connection more stable.

[0030] As shown in the drawings, Figures 3-5 The hook 501 described in the application includes a first extension wall 5011 extending outside the front clamping plate 1 and arranged perpendicularly thereto, and a second extension wall 5012 extending perpendicularly along the end face of the first extension wall 5011. With the above structure, the hook structure and the hook groove are effectively hooked, and there is no thickness direction shaking or displacement.

[0031] As shown in the drawings, Figure 4 and 6As shown, the inner wall of the front lock body 1 is provided with a baffle 102 abutting against the second extension wall 5012, and a hook groove 101 is formed between the baffle 102 and the inner wall of the front lock body 1. Specifically, the hook is a 7-shaped hook, that is, the first extension wall extends outwardly perpendicularly to the body of the front clamping plate, and the second extension wall extends perpendicularly at the tail end of the first extension wall and is parallel to the body of the front clamping plate, and the extension direction of the second extension wall is consistent with the abutting surface of the baffle. With the above structure, effective hooking is achieved between the hook groove and the hook, and the thickness direction will not shake or shift.

[0032] As shown in the accompanying drawings Figure 2 and 6 As shown, the hook groove 101 is arranged at one end of the front lock body 1 in the length direction. Specifically, the front lock body has a certain depth, forming a groove in the thickness direction, and then the hook groove is arranged on the inner side wall of one end of the groove in the length direction. With this structure, as long as one end of the front lock body is provided with a hook groove corresponding to the hook, the connection between the front clamping plate and the front lock body can be achieved. Moreover, during assembly, since only one end is provided with a hook groove, the placement of the hook is facilitated, and assembly is more convenient. It will not cause the situation that both ends are provided with hooks, and the second extension wall is easily blocked by the baffle of the hook groove and cannot be hooked.

[0033] As shown in the accompanying drawings Figures 1-2 , 3 and 5, the connecting piece 5 further comprises a connecting plate 304 arranged symmetrically on the front clamping plate 301 in the length direction, the connecting plate 304 extends towards the front lock body 1, and the connecting plate 304 is provided with a first connecting hole 305; correspondingly, the front lock body 1 is provided with a second connecting hole 103, which is arranged on the side wall at both ends of the front lock body in the length direction and penetrates the side wall to align with the first connecting hole, and the second connecting hole 103 and the first connecting hole 305 are connected by a screw 6. The screw here can be a tamper-proof screw, so as to avoid damage to the lock body. With the above structure, after the hook and the hook groove are hooked, the front clamping plate and the front lock body are further connected through the connecting holes, so as to avoid shaking between the two and realize fixed assembly.

[0034] More specifically, when the hook 501 at one end of the front clamping plate 301 along its length is engaged with the corresponding groove 101 of the front lock body 1, at least the screw 6 at the opposite end of the front clamping plate 301 along its length connects the second connecting hole 103 and the first connecting hole 305; that is, the front clamping plate and the front lock body are engaged at one end along their length by hooks and grooves, and the corresponding other end is fastened by screws and the second connecting hole and the first connecting hole; that is, one end of the opposite ends is engaged by the hook and groove structure of this application, and the other end is fastened by screws and the second connecting hole and the first connecting hole, thus achieving a stable connection between the front clamping plate and the front lock body, which is not prone to loosening or separation.

[0035] As attached Figure 5 As shown, the connecting plate 304 described in this application is located in the center of each set of hooks 501, that is, two hooks at each end of the length direction are alternately arranged with a connecting plate, and the connecting plate is located in the middle position; with this structure, the three connection points can be evenly distributed, making the connection between the front clamp plate and the front lock body more stable.

[0036] As attached Figure 5 As shown, the connecting plate 304 described in this application is provided in two pieces, and the two connecting plates 304 are symmetrically arranged vertically along the length of the front clamping plate 301. With this structure, the upper and lower ends of the front clamping plate and the front lock body can be fixed by screws, which further improves the stability of the connection between the two. Moreover, when the clamping plate is upright or inverted, one end is always provided with a connecting plate.

[0037] As attached Figure 5 As shown, the second extension wall 5012 described in this application extends toward both ends of the front clamping plate 1 along its length direction; specifically, the second extension wall located at the upper end of the front clamping plate extends upward, and the second extension wall located at the lower end of the front clamping plate extends downward. This extension direction can achieve a stable connection with the hook groove, making it difficult to disengage and convenient for assembly.

[0038] As attached Figure 1 , 2 As shown in Figure 6, the second connecting hole 103 described in this application is located on the side wall of one of the upper and lower ends along the length of the front lock body 1, and the second connecting hole 103 is arranged opposite to the hook groove 101 in the upper and lower directions; that is, the second connecting hole is located on the side wall of the thickness extension end of the upper and lower ends of the front lock body, and the first connecting hole and the hook groove are arranged opposite to each other, that is, located at the upper and lower ends respectively, not at the same end; and the second connecting hole is aligned with the first connecting hole on the connecting plate, and the two are fastened by screwing; in this way, one end of the front lock body and the front clamping plate are connected by hooking, and the other end is fastened by screws, making the connection tighter and more secure.

[0039] As attached Figures 2-3 As shown in Figure 7, the connector 5 on the rear clamping plate 302 described in this application consists of first mounting holes 502 symmetrically arranged vertically along its length. Correspondingly, the rear lock body 2 is provided with a second mounting hole 201. The first mounting holes 502 and the second mounting holes 201 are connected by screws. Specifically, multiple first mounting holes can be provided along the vertical length of the rear clamping plate, and the number of holes can be set according to the specific connection requirements. However, the vertical direction needs to be symmetrically arranged to ensure that the plate can be assembled with the second mounting holes whether it is upright or inverted. With this structure, the symmetrical mounting holes can enable the rear clamping plate to be connected with the rear lock body whether it is upright or inverted, thus not being limited by the left or right side door panel orientation. One set of locks can meet the assembly of door panels in different orientations.

[0040] The door lock mechanism of this application can be a fingerprint lock, a password lock, a mechanical lock, or a facial recognition lock; specifically, it can include a main lock body and a secondary lock body, and both the main lock body and the secondary lock body can include a front lock body, a rear lock body, and a middle clamping plate; the clamping plate structure adopts the clamping plate structure with symmetrical connecting parts set at the top and bottom as described above in this application, which can achieve the effect that the left and right door panels of this application can be assembled with a set of locks; this application can set different internal structures according to the above-mentioned types of locks, all of which are necessary components required by conventional lock structures in the art, and do not need to be described in detail here; the most important innovation of this application lies in the structure of the connecting parts between the clamping plate and the corresponding front and rear lock bodies.

[0041] The door lock mechanism of this application has the following working principle and process: A hook structure in the shape of a "7" and a first connecting hole are provided on the front clamping plate of the clamping plate. A latching groove is provided at the mating position of the front lock body and the "7" hook of the clamping plate. Both the "7" hook and the first connecting hole are symmetrically designed along the vertical length of the clamping plate. At least one end of the front lock body has a slot that mates with the "7" hook of the clamping plate. The front lock body can be reversed and inserted into the "7" hook of the clamping plate to form a fixed position. Then, anti-tamper screws are used to fix the clamping plate and the outer shell of the front lock body to complete the fixed assembly. The rear lock body can be fixed by connecting screws in the corresponding first and second mounting holes. Then, the door panel is inserted through the side opening of the clamping plate. The door panel is inserted into the receiving groove and connected to the clamping plate, thus enabling use. Since the connecting parts on the clamping plate of this application are symmetrically arranged vertically, whether the clamping plate is placed upright or rotated 180 degrees inverted, please refer to the appendix for details. Figure 8As shown, the structures of the connecting pieces do not affect the assembly of the front lock body and the rear lock body, when the door plates of different sides are installed, only the direction of the inner clamping plates needs to be adjusted, and the angles of the front lock body and the rear lock body do not need to be changed, so that the assembly of the door plates of different sides can be completed; therefore, the above-mentioned door lock mechanism does not need to be provided in multiple types, one structure can meet the assembly of the door plates of different sides, installation is convenient, and users will not be disturbed, and adjustment is convenient.
