Description

Technical Field

[0001] The present invention relates to the technical field of electric control locks, and in particular to an electric bolt lock. The present invention also relates to a glass door lock equipped with the electric bolt lock. Background Art

[0002] Glass door access control generally uses two types of locks: electric bolt locks and magnetic locks. Among them, electric bolt locks are generally divided into two categories on the market: one is the power-off opening type, which is used in general access control places and is convenient for escape. The disadvantage is that the door can be opened when the power is off, which is not very safe. Generally, people need to add an extra lock after get off work, which is very troublesome; the second is the power-off locking type, which is generally used in places with a higher security level. It is locked after the power is off. This usually requires a spare mechanical key for emergency use. The installation is more troublesome. In some occasions, there is not enough space for installing this type of lock, and it is not convenient to escape when the power is off. These two types of locks have limited opening methods due to the mechanical transmission principle itself, and the lock needs to be powered on for a long time. This structure generates a lot of heat and has poor stability. Moreover, users can only choose one of the structures, and cannot take into account its advantages. Summary of the invention

[0003] In view of this, the present invention aims to provide an electric bolt lock, which can keep the locking tongue in a positioned state after power is turned on instantly.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] An electric bolt lock is installed on a door frame, and the electric bolt lock comprises:

[0006] A main lock body, in which a first electromagnet for driving a lock tongue to extend or retract the main lock body is provided, and an elastic reset member provided in the main lock body and connected to the lock tongue, wherein a limiting portion is constructed at the other end of the first electromagnet relative to one end connected to the lock tongue;

[0007] A positioning component is arranged in the main lock body and is located at one end of the first electromagnet. The positioning component has a limiting end face that flips back and forth relative to the main lock body. The limiting portion abuts against the positioning component. Due to the drive of the first electromagnet, the limiting portion pushes the limiting end face to rotate and abuts against the limiting end face to maintain the positioning state of the lock tongue on the main lock body.

[0008] Furthermore, a driving source for driving the positioning assembly to release the locking tongue from maintaining a positioning state is provided in the main lock body.

[0009] Furthermore, the positioning assembly includes a first card block rotatably arranged relative to the main lock body, and a second card block rotatably arranged on the first card block. The limiting end face is constructed on the first card block, and due to the rotation of the second card block, the second card block can be pressed against the first card block and drive the first card block to rotate in the same direction as the second card block.

[0010] Furthermore, elastic members are provided on the rotating shaft of the first clamping block and the rotating shaft of the second clamping block, and the elastic members are configured to drive the first clamping block and the second clamping block to return to their original positions after rotation.

[0011] Furthermore, the elastic member is a torsion spring sleeved on the rotating shaft of the first clamping block and the rotating shaft of the second clamping block.

[0012] Furthermore, the driving source has a driving end that can receive an external signal and have an extended state or a shortened state. In the extended state, the driving end can push the second card block to rotate so as to drive the first card block to rotate, and the limiting portion moves linearly due to the rotation of the first card block and the elastic force of the elastic reset member to release the abutment with the limiting end face.

[0013] Furthermore, the limiting portion is a limiting block screwed to one end of the first electromagnet.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) The electric bolt lock of the present invention can, by means of a positioning assembly, enable the first electromagnet for driving the lock tongue to be limitedly abutted against the limit end surface by the limit portion after being energized instantaneously, thereby enabling the lock tongue to remain positioned relative to the main lock body, and to maintain the unlocked state of the lock tongue after the first electromagnet is powered off, that is, the electric bolt lock can maintain the positioned state of the lock tongue, and its structural design is ingenious and has a good use effect.

[0016] (2) The driving source provided can drive the positioning assembly to release the positioning state of the lock tongue, and under the elastic force of the elastic reset member, the lock tongue can be reset to the locked state extending out of the main lock body, that is, the lock tongue can be switched between the unlocked state and the locked state by the driving of the driving source. In particular, when the driving source adopts a push-pull electromagnet, the lock tongue can be switched between the unlocked state and the locked state by instantaneous power supply, which has the advantages of low power consumption and low cost, and more reliable stability of the lock tongue in unlocking and locking.

[0017] (3) By means of a first rotatable clamping block and a second clamping block rotatable relative to the first clamping block, the second clamping block can be pressed against the first clamping block during rotation, and drive the first clamping block to rotate in the same direction as the second clamping block, so that the limiting portion can be smoothly released from the contact with the limiting end face.

[0018] (4) The elastic member provided can help the first clamping block and the second clamping block to return to their original positions smoothly after rotation.

[0019] (5) The elastic member adopts a torsion spring, which has good elastic force and is easy to obtain. At the same time, it has a relatively simple structure and is easy to install.

[0020] (6) The second clamping block is pushed to rotate by the driving end, thereby causing the first clamping block to rotate, and the limiting portion moves along a straight line under the action of the rotation of the first clamping block and the elastic force of the elastic reset member, thereby releasing the abutment with the limiting end face.

[0021] (7) The limit block is screwed onto the first electromagnet. This structure is relatively simple and is firmly and reliably connected to the limit end surface, thereby making the positioning state of the lock tongue stable and reliable.

[0022] In addition, another object of the present invention is to provide a glass door lock, the glass door lock comprising the electric bolt lock as described above, and a glass door clamp provided on a door body and engaged with the electric bolt lock, the glass door clamp comprising:

[0023] A secondary lock body, on which a cover plate is turned over and provided, and in a buckled and locked state of the cover plate, a lock tongue hole for inserting the lock tongue is formed between the cover plate and the secondary lock body;

[0024] A driving component is arranged in the auxiliary lock body, and the driving component includes a driving device, and a clamping end arranged at the power output end of the driving device and capable of constituting the cover plate to maintain the buckled locking state. Corresponding to the clamping end, a clamping groove for the clamping end to be clamped is provided on the cover plate. Due to the driving of the driving device, the clamping end can be disengaged from the clamping groove to release the buckled locking state with the cover plate.

[0025] Furthermore, a flip plate is pivotally provided on the auxiliary lock body, and an outwardly convex block is constructed at the other end of the flip plate relative to one end of the pivotal connection, and the block constitutes the clamping end.

[0026] Furthermore, a connecting rod is hinged between the power output end of the driving device and the flip plate, so that under the drive of the driving device, the connecting rod constitutes a traction for rotating the flip plate relative to the auxiliary lock body.

[0027] The glass door lock of the present invention adopts the electric bolt lock and the glass door clamp as described above, wherein the glass door clamp has the function of realizing emergency unlocking by opening the reversible cover plate when the lock tongue cannot be retracted into the main lock body. The glass door lock has the advantages of low power consumption, low cost and more reliable stability of lock tongue unlocking and locking, and also has the function of emergency unlocking, which can effectively avoid the trouble of spare keys, thereby having a better use effect.

DETAILED DESCRIPTION

[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0042] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] The present embodiment relates to an electric bolt lock, which is installed on a door frame. The electric bolt lock mainly includes a main lock body and a positioning assembly arranged in the main lock body door body, wherein a first electromagnet for driving a lock tongue to extend or retract the main lock body is arranged in the main lock body, and an elastic reset member is arranged in the main lock body and connected to the lock tongue. A limiting portion is constructed at the other end of the first electromagnet relative to one end connected to the lock tongue. The positioning assembly is located at one end of the first electromagnet, and the positioning assembly has a limiting end face that flips back and forth relative to the main lock body. The limiting portion abuts against the positioning assembly. Due to the drive of the first electromagnet, the limiting portion pushes the limiting end face to rotate and abuts against the limiting end face to maintain the positioning state of the lock tongue on the main lock body.

[0045] The following is a detailed description of the electric bolt lock 3 as a glass door lock, taking the glass door lock equipped with the electric bolt lock 3 as an example, wherein an exemplary structure of the glass door lock is as follows: Figure 1 and Figure 2As shown, it includes an electric latch 3 arranged on a door frame 1 and a glass door clamp 4 arranged on a door body 2.

[0046] In terms of specific structure, an exemplary structure of the electric lock 3 of this embodiment is as follows: Figure 3 and Figure 4 As shown, the electric bolt lock 3 includes a main lock body 31 and a positioning assembly 37 disposed in the main lock body 31. The main lock body 31 is connected to the door frame 1 through a connecting member 11 passing through a fixing hole 30, wherein the connecting member 11 can be a bolt or a countersunk screw. Figure 4 As shown, a first electromagnet 32 ​​for driving a lock tongue 35 to extend out of or retract into the main lock body 31 is provided in the main lock body 31, and a lock tongue hook 34 pivoted relative to the main lock body 31 is provided at one end of the electromagnet shaft of the first electromagnet 32, and one end of the lock tongue hook 34 is connected to the lock tongue 35, so that when the lock tongue hook 34 rotates, the lock tongue 35 can be driven to move linearly, so as to extend out of the main lock body 31 or retract into the main lock body 31. A connecting rod 33 is hinged between the other end of the lock tongue hook 34 and the electromagnet shaft, so that the lock tongue hook 34 can be driven to rotate under the linear motion of the electromagnet shaft.

[0047] It should be noted that the movement direction of the electromagnet shaft is perpendicular to the movement direction of the lock tongue 35, that is, the lock tongue 35 moves linearly along the height direction of the door body 2, and the electromagnet shaft moves linearly along the width direction of the door body 2. In order to facilitate the reset of the lock tongue 35 along the linear motion, an elastic reset member connected to the lock tongue 35 is provided in the main lock body 31. The elastic reset member is specifically a lock tongue torsion spring 341 provided on the rotating shaft of the lock tongue hook 34. One end of the lock tongue torsion spring 341 abuts against the lock tongue 35, so that after the first electromagnet 32 ​​is powered off and the limit portion 321 is released from the limit, the lock tongue 35 can be reset under the elastic force of the lock tongue torsion spring 341, that is, the lock tongue 35 can extend out of the main lock body 31 to be in a locked state.

[0048] Continue to view Figure 4 As shown, relative to one end provided with the locking tongue 35, a limiting portion 321 is constructed at the other end of the first electromagnet 32, that is, at the other end of the electromagnet shaft, and the limiting portion 321 can be limited on the limiting end face 3711 described below. Specifically, the limiting portion 321 of this embodiment is a rectangular limiting block screwed to one end of the first electromagnet 32. Of course, the limiting portion 321 can also adopt a special square head nut. The limiting block is screwed to the first electromagnet 32 ​​to facilitate the installation of the limiting block. In addition, the structure of the rectangular limiting block is relatively simple, and it can be firmly and reliably abutted with the limiting end face 3711, so that the positioning state of the locking tongue 35 is stable and reliable.

[0049] Depend on Figure 4 Combination Figure 5 and Figure 6 As shown, the positioning assembly 37 is located at one end of the first electromagnet 32 ​​provided with a limiting portion 321. The positioning assembly 37 has a limiting end face 3711 that flips back and forth relative to the main lock body 31. The limiting portion 321 abuts against the positioning assembly 37. Due to the drive of the first electromagnet 32, the limiting portion 321 pushes the limiting end face 3711 to rotate and abut against the limiting end face 3711, thereby maintaining the positioning state of the lock tongue 35 on the main lock body 31. By setting the positioning assembly 37, the lock tongue 35 can be kept in position relative to the main lock body 31 after the first electromagnet 32 ​​that drives the lock tongue 35 is energized instantly, and the lock tongue 35 can be kept in an unlocked state after the first electromagnet 32 ​​is powered off.

[0050] In terms of specific structure, the positioning assembly 37 of this embodiment includes a first block 371 rotatably set relative to the main lock body, and a second block 372 rotatably set on the first block 371. The limiting end face 3711 is constructed on the first block 371, and due to the rotation of the second block 372, the second block 372 can be pressed against the first block 371 and drive the first block 371 to rotate in the same direction as the second block 372, so that the limiting portion 321 can be smoothly released from the abutment with the limiting end face 3711.

[0051] In order to provide a rotation connection basis for the first clamping block 371 to rotate, a U-shaped guide groove 373 is fixedly connected in the main lock body 31, and a first shaft hole 3712 is formed on the guide groove 373. The first clamping block 371 rotates relative to the guide groove 373 through the shaft passing through the first shaft hole 3712. The second clamping block 372 is pivotally connected to the first clamping block 371 through the second shaft hole 3713 provided on the first clamping block 371, and one end of the second clamping block 372 can be tightly pressed against the first clamping block 371, and the other end can be tightly pressed against the bottom of the guide groove 373, so that the second clamping block 372 can reciprocate within a certain angle range.

[0052] In order to facilitate the return of the first clamping block 371 and the second clamping block 372 after rotation, elastic members are provided on the rotating shaft of the first clamping block 371 and the rotating shaft of the second clamping block 372, and the elastic members can drive the first clamping block 371 and the second clamping block 372 to return smoothly after rotation. In view of the fact that the torsion spring has good elastic force and is easy to obtain, and has a relatively simple structure and is easy to install, in this embodiment, the elastic member is preferably a torsion spring sleeved on the rotating shaft of the first clamping block 371 and the rotating shaft of the second clamping block 372, that is, Figure 4 The first torsion spring 374 corresponding to the first clamping block 371 and the second torsion spring 375 corresponding to the second clamping block 372 are shown in FIG. 1 , so that the first clamping block 371 and the second clamping block 372 are Figure 4After the clockwise rotation as shown in FIG, it can smoothly return to its original position under the elastic force of the first torsion spring 374 and the second torsion spring 375.

[0053] As a further improvement of this embodiment, in this embodiment, a driving source for driving the positioning assembly 37 to release the positioning state of the lock tongue 35 is provided in the main lock body 31. The driving source has a driving end 361 that can receive an external signal and has an extended state or a shortened state. The driving end 361 can push the second clamping block 372 to rotate in the extended state, so as to drive the rotation of the first clamping block 371, and the limiting portion 321 moves due to the rotation of the first clamping block 371 and the elastic force of the elastic reset member to release the abutment with the limiting end surface 3711.

[0054] like Figure 4 As shown in the figure, the driving source adopts a push-pull electromagnet, that is, the second electromagnet 36 shown in the figure, wherein one end of the moving iron core of the second electromagnet 36 constitutes the driving end 361. The second electromagnet 36 is energized, and the driving end 361 extends outward to push the second clamping block 372 to rotate, thereby driving the first clamping block 371 to rotate, and under the rotation of the first clamping block 371 and the elastic force of the elastic reset member, the limiting portion 321, that is, the limiting block, can move linearly along the width direction of the door body 2, thereby releasing the abutment with the limiting end face 3711, so that the lock tongue 35 is reset to the locked state extending out of the main lock body 31.

[0055] In this embodiment, the unlocking state or locking state of the lock tongue 35 can be switched by driving the driving source. In particular, when the driving source adopts a push-pull electromagnet, the unlocking state or locking state of the lock tongue 35 can be switched by instantaneous power supply. This structure has low power consumption and low cost, and the stability of unlocking and locking of the lock tongue 35 is more reliable.

[0056] The structure of the glass door clamp 4 in this embodiment is as follows Figures 7 to 9 As shown, the glass door clamp 4 is arranged on the door body 2, and is plugged and matched with the above-mentioned electric bolt lock 3 to realize the closing of the door body 2. Specifically, the glass door clamp 4 of this embodiment includes a secondary lock body 41 and a driving component arranged in the secondary lock body 41, wherein the secondary lock body 41 is formed with mounting grooves 50 for clamping on both sides of the door body 2, and mounting holes 411 for external connecting parts to be screwed to fasten the secondary lock body 41 to the door body 2.

[0057] As a further improvement of this embodiment, in this embodiment, a cover plate 44 is turned over on the auxiliary lock body 41, and in the buckled locked state of the cover plate 44, a lock tongue hole 40 for inserting the lock tongue 35 is formed between the cover plate 44 and the auxiliary lock body 41. The driving assembly includes a driving device, and a clamping end 431 provided at the power output end 421 of the driving device and capable of constituting the cover plate 44 to maintain the buckled locked state. Corresponding to the clamping end 431, a clamping groove 442 for clamping the clamping end 431 is provided on the cover plate 44. Due to the driving of the driving device, the clamping end 431 can be disengaged from the clamping groove 442 to release the buckled locked state with the cover plate 44.

[0058] For specific structure, see Figure 8 and Fig. 9 As shown, the cover plate 44 is pivotally mounted on the auxiliary lock body 41 through a rotating shaft passing through the pivot hole 441, and the aforementioned snap-in slot 442 is configured at the other end of the cover plate 44 relative to one end of the pivotal connection. A flip plate 43 is also pivotally mounted on the auxiliary lock body 41, and a convex block is configured at the other end of the flip plate 43 relative to one end of the pivotal connection of the flip plate 43, and the convex block constitutes the aforementioned snap-in end 431, and can be snap-fitted with the snap-in slot 442, so that the cover plate 44 and the auxiliary lock body 41 can surround and form a lock bolt hole 40 for inserting the lock bolt 35.

[0059] The driving device of this embodiment adopts a push-pull electromagnet, that is, Figure 8 and Fig. 9 The third electromagnet 42 shown in the figure has a connecting rod 45 hinged between the power output end 421 of the electromagnet and the flip plate 43, so that under the drive of the driving device, the connecting rod 45 constitutes a traction for the flip plate 43 to rotate relative to the auxiliary lock body 41. Specifically, the connecting rod 45 is a hook bent in a U shape, and the two free ends of the hook are respectively inserted into the third electromagnet 42 and the flip plate 43, so that when the third electromagnet 42 is energized, the connecting rod 45 can be driven to move, so as to drive the flip plate 43 to flip, so that the clamping end 431 on the flip plate 43 is released from the clamping groove 442, and then the cover plate 44 can be flipped open, so that when the lock tongue 35 is in the locked state, the door body 2 can be opened in an emergency. Of course, in addition to the above structure, the connecting rod 45 can also be a connecting rod, and the two ends of the connecting rod are respectively hinged on the third electromagnet 42 and the flip plate 43.

[0060] In order to facilitate the smooth return of the flip plate 43 after it is rotated under the drive of the electromagnet, a third torsion spring 46 is installed on the pivot shaft to which the flip plate 43 is pivotally connected, so that the flip plate 43 can be smoothly reset under the action of the third torsion spring 46. Of course, a torsion spring can also be installed on the pivot shaft of the cover plate 44 to facilitate the reset of the cover plate 44 after it is flipped, so that the clamping end 431 on the flip plate 43 can be smoothly clamped into the clamping groove 442.

[0061] In addition, in order to facilitate power supply for the third electromagnet 42, in this embodiment, a main lock wireless charging module 10 is installed on the main lock body 31, and a secondary lock wireless charging module 20 connected to the main lock wireless charging module 10 is installed on the secondary lock body 41. It should be noted that the main lock wireless charging module 10 and the secondary lock wireless charging module 20 use the wireless charging circuit board in the prior art, so that the third electromagnet 42 can be powered separately. This structure is simple to install and easy to use.

[0062] In addition, the glass door lock of the present embodiment also includes a controller, which adopts the existing technology to connect with the electrical components on the lock, and the controller also adopts the existing technology. Through the control of the circuit and the setting of the software, the glass door lock of the present embodiment can be customized to the open state after the lock is powered off, or the function of the lock can be customized according to the time period. For example, the power-off locking logic can be executed at the end of the working hours at night, and the door body 2 will not open automatically after the power is off. The power-off unlocking mode can be executed during the day to facilitate the entry and exit of personnel. In addition, the normal power off can be set to the locked state of the lock tongue 35, and the lock tongue 35 can be set to be opened when the power is off in an emergency.

[0063] The glass door lock of this embodiment can switch the unlocking state or locking state of the lock tongue 35 by instant power-on through the electric bolt 3, and can realize emergency unlocking by opening the reversible cover plate 44 when the lock tongue 35 cannot be retracted into the main lock body 31 through the glass door clamp 4. The glass door lock has the advantages of low power consumption, low cost and more reliable unlocking and locking stability of the lock tongue 35, and also has the function of emergency unlocking, which can effectively avoid the trouble of spare keys, and thus has a better use effect.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
