Description

Technical Field

[0001] The present invention relates to the technical field of lock bodies, specifically to a lock tongue structure with impact buffering, a lock body, and a cabinet door with such a lock body. Background Art

[0002] Spring locks are widely used in fields such as doors and windows, cabinets, and electronic devices due to their excellent performance.

[0003] Specifically, a spring lock mainly consists of structures such as a lock tongue, a support spring, and a lock core. One end of the lock tongue is provided with an arc portion, which can play a role in buffering and automatic contraction during the closing process of doors and windows, cabinets, and electronic devices.

[0004] However, when a spring lock is applied to the above-mentioned cabinets, there are certain drawbacks. Mainly, when the cabinet door body adopts a double-leaf door opening method, it is necessary to first close the door body without a lock tongue and then close the door body with a lock tongue. That is, there are requirements for the closing sequence of the two door bodies of the double-leaf door. This requirement aims to protect the structure of the tongue lock and avoid the situation where after the door body with a lock tongue is closed first and then the door body without a lock tongue is closed, the door body impacts the plane on the side of the lock tongue away from its arc portion, causing the lock tongue structure to be damaged by the impact. This results in the phenomenon that the durability of ordinary spring locks is not high when applied to double-leaf doors and needs to be frequently replaced. Summary of the Invention

[0005] The purpose of the present invention is to provide a lock tongue structure with impact buffering, a lock body, and a cabinet door with such a lock body to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A lock tongue structure with impact buffering, which is arranged inside a housing body and includes: A first lock tongue and a second lock tongue, which are slidably arranged through the side of the housing body, and the first lock tongue is connected to an energy storage structure arranged inside the housing body; An insertion component, which connects the first lock tongue and the second lock tongue. When the first lock tongue or the second lock tongue is pressed and moves towards the inside of the housing body, the insertion component can make the first lock tongue and the second lock tongue move synchronously towards the inside of the housing body; A trigger, which is installed inside the housing body. The trigger cooperates with the insertion component and can separate the first lock tongue from the second lock tongue when the first lock tongue and the second lock tongue move to the end; An elastic locking component, which is arranged inside the housing body. The elastic locking component rolls and cooperates with a locking wheel installed on the second lock tongue and can lock the position of the second lock tongue when the second lock tongue moves to the end of the stroke.

[0007] As a further solution of the present invention: the energy storage structure includes an extension sleeve fixedly connected to the first locking tongue and a horizontal shaft provided on the outer housing. The horizontal shaft is slidably sleeved with the extension sleeve, and a first cylindrical spring is sleeved on the horizontal shaft. One end of the first cylindrical spring is connected to the extension sleeve, and the other end is connected to the end of the horizontal shaft.

[0008] As a further solution of the present invention: the insertion assembly includes a connecting plate detachably connected to the second locking tongue and a locking hole provided on the first locking tongue. A locking plate slidably mounted on the connecting plate can be inserted into the locking hole, and the connecting plate and the locking plate are connected by a third cylindrical spring; On one side of the first locking tongue facing the inside of the outer housing, there is a second inclined surface slidably adapted to the end of the locking plate.

[0009] As a further solution of the present invention: a contact wheel is rotatably mounted at one end of the locking plate away from the first locking tongue. The contact wheel is in rolling cooperation with a third inclined surface provided at the end of the trigger member, and can drive the locking plate to move away from the first locking tongue.

[0010] As a further solution of the present invention: the elastic locking assembly includes a guiding shaft fixedly mounted on the outer housing. A locking member is slidably mounted on the guiding shaft, and a second cylindrical spring is sleeved on the guiding shaft. One end of the second cylindrical spring is connected to the locking member, and the other end is connected to the end of the guiding shaft.

[0011] As a further solution of the present invention: one end of the locking member facing the locking wheel is provided with a first inclined surface, and a locking groove is provided at one end of the first inclined surface away from the locking wheel; When the locking wheel moves towards the locking member, the locking wheel can move to the locking groove through the first inclined surface.

[0012] The lock body, including the locking tongue structure for impact buffering, further includes: A rotating member rotatably mounted on the outer housing. A traction disc is provided on the rotating member, and a traction cable is wound around the traction disc. The traction cable bypasses a sheave rotatably mounted on the outer housing and is connected to the first locking tongue; A jacking assembly connecting the rotating member and the trigger member. The jacking assembly can drive the trigger member to move away from the rotating member when the rotating member rotates; A pressing structure connecting the rotating member and the locking member. The pressing structure can separate the locking member from the locking wheel when the rotating member rotates to the end of the stroke.

[0013] As a further solution of the present invention: The jacking assembly includes a sliding connection part arranged on the trigger part, and the sliding connection part is slidably connected with a guiding part arranged on the outer casing; The jacking assembly further includes a connecting plate fixedly connected with the trigger part and a driven part coaxially fixedly connected with the rotating part. A fitting wheel is rotatably installed on the connecting plate, and the fitting wheel can roll in a fitting groove arranged on the driven part; The fitting groove includes an arc groove arranged on the driven part and an inclined groove connected with the arc groove. When the fitting wheel rotates in the inclined groove, the trigger part can move away from the rotating part along the length direction of the guiding part.

[0014] As a further solution of the present invention: The pressing-down structure includes a pressing plate fixedly connected with the rotating part. When the pressing plate abuts and cooperates with a hook plate connecting the locking part, it can pull the locking part to separate from the locking wheel.

[0015] The cabinet door includes two groups of door body structures arranged oppositely. A lock body is arranged on one group of the door body structures, and a lock tongue hole adapted to the first lock tongue is arranged on the other group of the door body structures.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By arranging the first lock tongue and the second lock tongue, when the door panel with the first lock tongue and the second lock tongue closes first, the closing of the other door panel can act on the arc area of the second lock tongue, and under the action of the inserting assembly, the first lock tongue and the second lock tongue can move towards the inside of the outer casing at the same time. This not only effectively avoids the requirement for the closing sequence of the two opposite-opening door bodies by the existing lock tongue structure, but also effectively avoids the situation that the door body and the lock tongue structure are damaged due to impact caused by the closing sequence, improving the practicability and durability; By arranging the energy storage structure, when the door panel abuts against the arc area on the first lock tongue or the second lock tongue, it has a buffering effect on the door panel when it moves to the end of the stroke, avoiding the door panel directly hitting the cabinet body and causing the door panel to bounce open again during the closing process; By arranging the trigger part and the elastic locking assembly, when the first lock tongue and the second lock tongue move to the end of the stroke, the first lock tongue can be ejected and inserted into the lock tongue hole of the other door panel, and the second lock tongue can be locked. On the one hand, the locking effect is ensured, and on the other hand, the situation that the end of the second lock tongue pops out and forms an abutting state with the side part of the door panel, resulting in wear of the end of the second lock tongue when the door panel shakes, is avoided; Through the provided jacking assembly and pressing-down structure, during the unlocking process, the first locking tongue and the second locking tongue can form a stable connection relationship again, so as to ensure that the above steps can be repeated during the next closing of the door body, thereby protecting the physical structures of the door body, the first locking tongue and the second locking tongue.

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation mode.

[0030] Please refer to Figures 1 to 10 , in the embodiment of the present invention, the locking tongue structure for impact buffering is arranged in the outer housing 1 and includes: a first locking tongue 2, a second locking tongue 3, an insertion assembly, a trigger member 18 and an elastic locking assembly.

[0031] The first locking tongue 2 and the second locking tongue 3 are slidably arranged through the side part of the outer housing 1. The first locking tongue 2 is connected to an energy storage structure arranged inside the outer housing 1. Among them, the first locking tongue 2 and the second locking tongue 3 are slidably arranged relative to each other, and arc-shaped areas are arranged at the front ends of the sides of the first locking tongue 2 and the second locking tongue 3 that are outside the outer housing 1 and face away from each other. This setting enables the first locking tongue 2 or the second locking tongue 3 to perform a retraction action when abutting against another door panel, and under the action of the insertion assembly, the other locking tongue can move synchronously towards the inside of the outer housing 1, so as to be inserted into the locking tongue hole in the door panel; arc-shaped grooves are arranged on both the upper and lower sides of the first locking tongue 2 and the second locking tongue 3. One end of the arc-shaped groove far from the arc-shaped area is not completely penetrated through the first locking tongue 2 and the second locking tongue 3. An arc-shaped protrusion is arranged on the outer housing 1. The arc-shaped protrusion is in abutting cooperation with the end of the arc-shaped groove, and can produce a blocking effect on the first locking tongue 2 and the second locking tongue 3 when the arc-shaped areas of the first locking tongue 2 and the second locking tongue 3 protrude from the outer housing 1.

[0032] The energy storage structure includes an extension sleeve 4 fixedly connected to the first locking tongue 2 and a horizontal shaft 5 arranged on the outer housing 1. The horizontal shaft 5 is slidably sleeved with the extension sleeve 4, and a first cylindrical spring 6 is sleeved on the horizontal shaft 5. One end of the first cylindrical spring 6 is connected to the extension sleeve 4, and the other end is connected to the end of the horizontal shaft 5.

[0033] In the initial state, the first cylindrical spring 6 is in a compressed state. At this time, the first locking tongue 2 has a state in which the end of the arc-shaped groove far from the arc-shaped area is abutted against the outer housing 1 by being pushed by the first cylindrical spring 6. In this state, only the arc-shaped areas of the first locking tongue 2 and the second locking tongue 3 are outside the outer housing 1. When the door panel equipped with the first locking tongue 2 and the second locking tongue 3 is closed later or closed first, the first locking tongue 2 or the second locking tongue 3 can abut against another door panel, and under the action of the insertion assembly, the first locking tongue 2 and the second locking tongue 3 can move synchronously towards the inside of the outer housing 1, and further compress the first cylindrical spring 6. During this process, when the other door panel abuts against the arc-shaped area on the first locking tongue 2 or the second locking tongue 3, it can play a buffering effect on the movement of the door panel, avoiding the door panel directly hitting the cabinet body and causing the door panel to bounce open again during the closing process.

[0034] Please refer to Figures 4 to 6 、 Figure 8 The insertion assembly connects the first locking tongue 2 and the second locking tongue 3. The insertion assembly can enable the other locking tongue to move synchronously towards the inside of the outer housing 1 when the first locking tongue 2 or the second locking tongue 3 is pressed and moves towards the inside of the outer housing 1; The insertion component includes a connecting plate 12 detachably connected to the second locking tongue 3 and a locking hole 17 provided on the first locking tongue 2. A locking plate 14 slidably mounted on the connecting plate 12 can be inserted into the locking hole 17, and the connecting plate 12 and the locking plate 14 are connected by a third cylindrical spring 13. In the initial state, the third cylindrical spring 13 is in a stretched state. At this time, a stop portion 1401 provided on the locking plate 14 is in a state of abutting against the connecting plate 12, and at the same time, one end of the locking plate 14 away from the third cylindrical spring 13 is inserted into the locking hole 17. In this state, when the arc-shaped area on the first locking tongue 2 or the second locking tongue 3 collides with the door panel and moves towards the inside of the housing 1, the other locking tongue will move synchronously towards the inside of the housing 1. This not only effectively avoids the requirement for the closing sequence of the two opposite door bodies in the existing locking tongue structure, but also effectively avoids the damage of the door body and the locking tongue structure caused by the impact due to the closing sequence, improving the practicability and durability.

[0035] On the bottom side of the first locking tongue 2 facing the inside of the housing 1, a second inclined surface 16 slidably adapted to the end of the locking plate 14 is provided. When the first locking tongue 2 and the second locking tongue 3 move towards the inside of the housing 1 to the end of the stroke, the trigger 18 cooperates with the insertion component, so that the locking plate 14 can be separated from the locking hole 17. At this time, the first locking tongue 2 can be reset under the drive of the first cylindrical spring 6 to be inserted into the locking tongue hole, and the second locking tongue 3 can be locked under the action of the elastic locking component. When unlocking is required, inserting the key can drive the rotating member 22 to rotate, and the first locking tongue 2 is pulled back by the traction cable 25. At this time, one end of the locking plate 14 away from the third cylindrical spring 13 can abut against the second inclined surface 16, and under the action of the second inclined surface 16, the locking plate 14 can be re-guided into the locking hole 17, realizing the reconnection between the first locking tongue 2 and the second locking tongue 3, so that the above process can be repeated and the same technical effect can be achieved when closing the door body next time.

[0036] The trigger 18 is installed in the housing 1. The trigger 18 cooperates with the insertion component and can separate the first locking tongue 2 and the second locking tongue 3 when the first locking tongue 2 and the second locking tongue 3 move to the end. Further, a contact wheel 15 is rotatably installed at one end of the locking plate 14 away from the first locking tongue 2. The contact wheel 15 is in rolling cooperation with a third inclined surface 19 provided at the end of the trigger 18 and can drive the locking plate 14 to move away from the first locking tongue 2.

[0037] When the lock plate 14 is inserted into the lock hole 17, the first locking tongue 2 and the second locking tongue 3 are in a connected state, so that when the first locking tongue 2 or the second locking tongue 3 moves, the other locking tongue can follow and move synchronously. When the first locking tongue 2 and the second locking tongue 3 move towards the inside of the outer housing 1 to the end of the stroke, the abutting wheel 15 will abut against the third inclined surface 19, and the third inclined surface 19 has a tendency to guide the abutting wheel 15 to move away from the first locking tongue 2, so as to be able to separate the lock plate 14 from the lock hole 17. At this time, the elastic locking component locks the second locking tongue 3, and the first locking tongue 2 moves towards the locking tongue hole of the other door panel under the drive of the first cylindrical spring 6 to achieve the locking effect on the door panel.

[0038] Please refer to Figures 6 to 8 , the elastic locking component is arranged in the outer housing 1, and the elastic locking component is in rolling cooperation with the locking wheel 7 installed on the second locking tongue 3, and can lock the position of the second locking tongue 3 when the second locking tongue 3 moves to the end of the stroke; The elastic locking component includes a guiding shaft 9 fixedly installed on the outer housing 1. A locking member 8 is slidably installed on the guiding shaft 9, and a second cylindrical spring 10 is sleeved on the guiding shaft 9. One end of the second cylindrical spring 10 is connected to the locking member 8, and the other end is connected to the end of the guiding shaft 9; Specifically, one end of the locking member 8 facing the locking wheel 7 is provided with a first inclined surface 802, and a locking groove 801 is provided at the end of the first inclined surface 802 away from the locking wheel 7; When the locking wheel 7 moves towards the locking member 8, the locking wheel 7 can move to the locking groove 801 through the first inclined surface 802.

[0039] In this application, no matter the other door panel acts on the first locking tongue 2 or the second locking tongue 3, the first locking tongue 2 and the second locking tongue 3 can both move synchronously towards the inside of the outer housing 1. When the first locking tongue 2 and the second locking tongue 3 move to the end of the stroke, the locking wheel 7 on the second locking tongue 3 can abut against the first inclined surface 802. When the locking wheel 7 acts on the first inclined surface 802, it can make the locking member 8 move towards the second cylindrical spring 10 and compress the second cylindrical spring 10. After the locking wheel 7 moves to the end of the first inclined surface 802, the locking wheel 7 can enter the locking groove 801. At this time, the second cylindrical spring 10 can release elastic potential energy to make the locking wheel 7 fit against the inner side of the locking groove 801. In this state, the second locking tongue 3 is in a locked state. At the same time, the third inclined surface 19 can cooperate with the abutting wheel 15 to separate the lock plate 14 from the lock hole 17, and make the first locking tongue 2 pop out towards the outside of the outer housing 1 to be inserted into the locking tongue hole of the other door panel to achieve the locking effect on the door panel.

[0040] Among them, by locking the second locking tongue 3, it is possible to prevent the second locking tongue 3 from popping out, resulting in the end of the second locking tongue 3 coming into contact with the side of the door panel, causing wear at the end of the second locking tongue 3 when the door panel shakes.

[0041] Please refer to Figure 3 、 Figures 8 to 10 As an embodiment of the present invention, a lock body is also proposed, including the locking tongue structure for impact buffering described above, and further including: a rotating member 22, a lifting assembly, and a pressing-down structure.

[0042] The rotating member 22 is rotatably installed on the outer housing 1. A traction disc 27 is provided on the rotating member 22. A traction cable 25 is wound around the traction disc 27. The traction cable 25 bypasses a sheave 26 rotatably installed on the outer housing 1 and is connected to the first locking tongue 2. Among them, a lock core structure (not shown in the figure) is connected to the rotating member 22. When a corresponding key is inserted into the lock core structure, the rotating member 22 can be driven to rotate by the key, and the traction disc 27 rotates to wind up the traction cable 25, thereby pulling the first locking tongue 2 to achieve the purpose of unlocking.

[0043] The lifting assembly is connected to the rotating member 22 and the trigger member 18. The lifting assembly can drive the trigger member 18 to move away from the rotating member 22 when the rotating member 22 rotates. The lifting assembly includes a sliding connection portion 1801 provided on the trigger member 18, and the sliding connection portion 1801 is slidably connected to a guide member 24 provided on the outer housing 1; The lifting assembly further includes a connecting plate 20 fixedly connected to the trigger member 18 and a driven member 23 coaxially and fixedly connected to the rotating member 22. A fitting wheel 21 is rotatably installed on the connecting plate 20, and the fitting wheel 21 can roll in a fitting groove provided on the driven member 23; The fitting groove includes an arc groove 2302 provided on the driven member 23 and an inclined groove 2301 connected to the arc groove 2302. Among them, the center of the arc groove 2302 is concentric with the rotation center of the rotating member 22. When the fitting wheel 21 rotates in the inclined groove 2301, the trigger member 18 can move away from the rotating member 22 along the length direction of the guide member 24.

[0044] In the initial state, the rotating member 22 is axially locked due to its connection with the lock core structure. At this time, the driven member 23 is also in a locked state. In this state, the fitting wheel 21 is in a state away from the arc groove 2302 in the inclined groove 2301. In this state, the heights of the fitting wheel 21 and the trigger member 18 are constant, and in this height state, the third inclined surface 19 has the ability to cooperate with the abutting wheel 15 to drive the lock plate 14 away from the lock hole 17.

[0045] When unlocking, the rotating member 22 is rotated by the key. At this time, the driven member 23 can rotate. During the rotation of the driven member 23, the engaging wheel 21 can move along the length direction of the inclined groove 2301 towards the arc groove 2302. At this time, the engaging wheel 21 will raise the height of the triggering member 18 through the connecting plate 20, and separate the third inclined surface 19 from the abutting wheel 15. At this time, the lock plate 14 is reset to the state where the stop portion 1401 abuts against the connecting plate 12. As the rotating member 22 continues to rotate, the engaging wheel 21 will move into the arc groove 2302. At this time, the height of the triggering member 18 will be constant. At the same time, the first locking tongue 2 can be pulled to move towards the stroke end inside the outer housing 1. When the first locking tongue 2 moves towards the inside of the outer housing 1 to the stroke end, the upper end of the lock plate 14 can cooperate with the second inclined surface 16, and under the guidance of the second inclined surface 16, the lock plate 14 can re-enter the lock hole 17.

[0046] Based on the above settings, during the unlocking process, a stable connection relationship can be formed between the first locking tongue 2 and the second locking tongue 3 again, so as to ensure that during the next closing of the door body, the above steps can be repeated to protect the physical structures of the door body, the first locking tongue 2 and the second locking tongue 3.

[0047] Please refer to Figure 5 、 Figure 7 The pressing structure is connected to the rotating member 22 and the locking member 8. When the rotating member 22 rotates to the stroke end, the pressing structure can separate the locking member 8 from the locking wheel 7. The pressing structure includes a pressing plate 28 fixedly connected to the rotating member 22. When the pressing plate 28 abuts and cooperates with the hook plate 11 connecting the locking member 8, it can pull the locking member 8 to separate from the locking wheel 7.

[0048] When the rotating member 22 rotates to make the first locking tongue 2 move towards the inside of the outer housing 1 to the stroke end, the pressing plate 28 can abut against the hook plate 11, driving the locking member 8 to move towards the second cylindrical spring 10, that is, the second cylindrical spring 10 is continuously compressed. After the locking wheel 7 is separated from the locking groove 801, the lock plate 14 will be inserted into the lock hole 17. At this time, the rotating member 22 is reversed to reset.

[0049] As an embodiment of the present invention, a cabinet door is also proposed, which includes two sets of door body structures arranged oppositely. The lock body is provided on one set of the door body structures, and a locking tongue hole adapted to the first locking tongue 2 is provided on the other set of the door body structures.

[0050] It should be noted that the door panel provided with the locking tongue hole should have a separate locking structure with the cabinet body, such as an electromagnetic lock, an electronic bolt lock, etc.
