Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to an energy-saving lock body structure. Background Technology

[0002] Currently, security locks are widely used in security doors and interior wooden doors on the market. These locks have evolved from the original purely mechanical locks to the current electronic security lock structure. Electronic security locks have batteries installed inside, which drive the lock cylinder to rotate. These batteries are generally rechargeable or AAA batteries. When these batteries are depleted, they need to be replaced. Therefore, there is data on how many times a single rechargeable or AAA battery can power the lock. The power consumption is determined by the angle of rotation of the lock body driven by the motor on the battery pack. Current lock cylinders, such as the one disclosed in patent application CN201520562947.1, which uses battery power to drive the lock cylinder to rotate, have a relatively large rotation angle and require a large amount of battery power each time, resulting in low battery life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an energy-saving lock body structure that is simple in structure, more energy-efficient and durable.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An energy-saving lock body structure includes a housing, a left top and bottom hook, a right top and bottom hook, a main slide plate assembly, a secondary slide plate assembly, and a handle base. The left and right top and bottom hooks are telescopically connected to the housing, and the main slide plate assembly and the secondary slide plate assembly are telescopically connected to the housing. A guide post is fixed on the housing, and the handle base is rotatably connected to the housing. The housing has slots distributed on one or both sides of the guide post. A linkage plate is sleeved on the guide post, and a limit block is connected to the bottom end of the linkage plate. The left and right top and bottom hooks have grooves distributed on their inner sides. The limiting block is located inside the slots and holes on the left and right top and bottom hooks. A push plate is hinged to the linkage plate. The guide post passes through the main slide plate assembly. A push plate is rotatably connected inside the housing. At least one auxiliary slide plate assembly is telescopically arranged on the housing and is connected to the push plate. The push plate is connected to the left and right top and bottom hooks. A transmission plate is rotatably connected to the guide post. An upper push plate is hinged to the transmission plate. A toggle piece is connected to the right end of the upper push plate. The toggle piece is sleeved on the handle seat.

[0006] A further technical solution is that the main slide plate assembly is also provided with a main slide plate guide hole and a limiting hole 1. A guide post is fixed on the linkage plate. The guide post is located in the limiting hole 1 and passes through the main slide plate guide hole. When the push plate is pushed to the right, it drives the linkage plate to rotate counterclockwise. The counterclockwise rotation of the linkage plate drives the guide post to move outward in the limiting hole 1. Since the guide post passes through the main slide plate guide hole on the main slide plate assembly, when the main slide plate assembly moves outward, it can only move vertically along the main slide plate guide hole, ultimately causing the main slide plate assembly to move outward and lock the door.

[0007] A further technical solution is that a linkage column is fixed on the linkage plate, and the push plate is rotatably connected to the linkage plate through the linkage column. When the push plate is moved, the linkage plate can be driven to rotate.

[0008] A further technical solution is that a connecting piece is also sleeved at the bottom of the handle seat, and the right end of the push plate is sleeved on the left end of the connecting piece, so that when the push plate moves to the right and drives the linkage plate to rotate, it can move stably in one direction and limit its range of motion.

[0009] A further technical solution is that the left and right top and bottom hooks are also distributed with limiting holes two, and the shell is fixed with limiting post one. The limiting post one passes through the limiting hole two, and the limiting hole two is restricted by the limiting post one. The left and right top and bottom hooks can only move left and right within the range of the limiting hole two. The limiting hole two is a horizontally distributed waist-shaped structure, and there are two sets of limiting holes two and limiting posts one on the left and right top and bottom hooks respectively.

[0010] A further technical solution is as follows: a limiting post two is fixed on the push plate; a limiting hole three is distributed on the auxiliary drag plate assembly; a toggle post is fixed on the left and right top and bottom hooks; the limiting post two penetrates the limiting hole three; a limiting hole five is also distributed on the housing; a limiting post three is fixed on the auxiliary drag plate assembly; the limiting post three penetrates the limiting hole five; and a limiting groove is also distributed on the push plate. When the left and right top and bottom hooks move to the left and right sides, the toggle post also moves outward on the left and right top and bottom hooks, and drives the push plate to rotate during the movement. During the rotation, the push plate drives the auxiliary drag plate assembly to move outward and lock through the limiting post two. When the left and right top and bottom hooks retract to the middle, the toggle post abuts against the edge of the push plate and drives the push plate to rotate downward. During the rotation, the auxiliary drag plate assembly moves downward and unlocks.

[0011] A further technical solution is that the housing has slots distributed in front of and behind the guide post, and two limiting blocks are fixed on the linkage plate, with the bottom ends of the two limiting blocks respectively built into the two slots. The slots have a fan-shaped structure, which can restrict the angle of the linkage plate during rotation, allowing it to rotate only within the range of the slots.

[0012] The beneficial effects of this utility model are as follows: This utility model provides an energy-saving lock body structure, which is equipped with a linkage plate. When the electronic lock cylinder rotates and pushes the lower push plate, the lower slide plate drives the linkage plate to rotate. The linkage plate uses the bottom limit block to rotate and drive the left and right top and bottom hooks to move left and right to lock, and at the same time drive the main slide plate assembly and the auxiliary slide plate assembly to lock. Similarly, the upper push plate drives the toggle plate to rotate and unlock, which can also reduce the rotation angle of the electronic lock cylinder. Compared with the existing electronic lock cylinder rotation angle, this utility model achieves the same toggle effect by shortening the rotation angle of the electronic lock cylinder, thereby reducing energy consumption of the electronic lock cylinder each time and making it more energy-efficient.

Detailed Implementation

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] See Figures 1 to 10 As shown, an energy-saving lock body structure includes a housing 1, a left top and bottom hook 2, a right top and bottom hook 13, a main slide plate assembly 9, a secondary slide plate assembly 3, and a handle seat 16. The left top and bottom hooks 2 and 13 are telescopically connected to the housing 1 from left to right. The main slide plate assembly 9 and 13 are telescopically connected to the housing 1 from front to back. A guide post 20 is fixed on the housing 1. The handle seat 16 is rotatably connected to the housing 1. The housing 1 has slots 19 distributed on one or both sides of the guide post 20. A linkage plate 18 is sleeved on the guide post 20. A limit block 22 is connected to the bottom end of the linkage plate 18. The left top and bottom hooks 2 and 13 have slots 21 distributed on their inner sides. The limiting block 22 is located inside the slot 21 and the hole 19 on the left top hook 2 and the right top hook 13. The linkage plate 18 is hinged with a push plate 17. The guide post 20 passes through the main slide plate assembly 9. The push plate 4 is rotatably connected inside the housing 1. The auxiliary slide plate assembly 3 is located on the housing 1 and is telescopically arranged with at least one set and is connected to the push plate 4. The push plate 4 is connected to the left top hook 2 and the right top hook 13. The guide post 20 is rotatably connected with a transmission plate 11. The transmission plate 11 is hinged with an upper push plate 14. The right end of the upper push plate 14 is connected with a toggle piece 15. The toggle piece 15 is sleeved on the handle seat 16.

[0027] The main slide assembly 9 also has a main slide guide hole 23 and a limiting hole 27. A guide post 24 is fixed on the linkage plate 18. The guide post 24 is located in the limiting hole 27. The guide post 20 passes through the main slide guide hole 23. When the push plate 17 is pushed to the right, it causes the linkage plate 18 to rotate counterclockwise. The counterclockwise rotation of the linkage plate 18 causes the guide post 24 to move outward in the limiting hole 27. Since the guide post 20 passes through the main slide guide hole 23 on the main slide assembly 9, when the main slide assembly 9 moves outward from the housing 1, it can only move vertically along the main slide guide hole 23, ultimately causing the main slide assembly 9 to move outward and lock the door. A linkage post 25 is also fixed on the linkage plate 18. The push plate 17 is rotatably connected to the linkage plate 18 through the linkage post 25. When the push plate 17 is moved, it can drive the linkage plate 18 to rotate. A connecting piece 26 is also sleeved at the bottom of the handle base 16. The right end of the push plate 17 is sleeved on the left end of the connecting piece 26, which allows the push plate 17 to move to the right and drive the linkage piece 18 to rotate in a stable unidirectional direction, thus limiting its range of motion. Limiting holes 22 are also distributed on the left and right hooks 2 and 13. A limiting post 10 is fixed on the housing 1. The limiting post 10 passes through the limiting hole 22. The limiting hole 22 is restricted by the limiting post 10. The left and right hooks 2 and 13 can only move left and right within the range of the limiting hole 22. The limiting hole 22 is a horizontally distributed waist-shaped structure, and there are two sets of limiting holes 22 and two sets of limiting posts 10 on the left and right hooks 2 and 13 respectively. Limiting post 2 5 is fixed on the push plate 4, limiting hole 3 6 is distributed on the auxiliary slide plate assembly 3, and actuating post 29 is fixed on the left top hook 2 and right top hook 13. Limiting post 2 5 passes through limiting hole 3 6. Limiting hole 5 8 is also distributed on the housing 1. Limiting post 3 7 is fixed on the auxiliary slide plate assembly 3. Limiting post 3 7 passes through limiting hole 5 8. Limiting groove 30 is also distributed on the push plate 4. When the left top hook 2 and right top hook 13 move to the left and right sides, the actuating post 29 also moves outward on the left top hook 2 and right top hook 13. During the movement, the push plate 4 rotates. During the rotation, the push plate 4 drives the auxiliary slide plate assembly 3 to move outward and lock through limiting post 2 5. When the left top hook 2 and right top hook 13 retract to the middle, the actuating post 29 abuts against the edge of the push plate 4 and drives the push plate 4 to rotate downward. During the rotation, the auxiliary slide plate assembly 3 moves downward and unlocks. The housing 1 has slots 19 distributed in front of and behind the guide post 20. Two limiting blocks 22 are fixed on the linkage plate 18, and the bottom ends of the two limiting blocks 22 are respectively built into the two slots 19. The slots 19 have a fan-shaped structure, which can limit the angle of the linkage plate 18 when it rotates, and it can only rotate within the range of the slots 19.

[0028] In this embodiment, as Figure 1 , Figure 4 and Figure 5As shown, when normal unlocking is required, the electronic lock cylinder (not shown) drives the push plate 14 to the right, which in turn drives the actuating plate 15 to rotate clockwise. The clockwise rotation of the actuating plate 15 then actuates the right-side latch assembly 28 to unlock and open the door. When anti-theft functionality is required, the electronic lock cylinder drives the push plate 17 to the right, and through the linkage column 25, drives the linkage plate 18 to rotate counterclockwise. At this time, the guide column 24 on the linkage plate 18 also rotates counterclockwise, driving the main slide plate assembly 9 upward, causing the main slide plate assembly 9 to move and lock. The rotation of the linkage plate 18 drives the left and right deadbolts 2 and 13 to... The limiting block 22 on the linkage plate 18 abuts, and when the linkage plate 18 rotates, it will also drive the left and right top hooks 2 and 13 to move to the left and right ends to lock. At the same time, the left and right top hooks 2 and 13 move outward, driving the actuating column 29 to move to the left and right ends. During the movement, the push plate 4 will rotate upward, and the upward rotation of the push plate 4 will also drive the auxiliary slide plate assembly 3 to lock upward. In this way, the main slide plate assembly 9, the auxiliary slide plate assembly 3, and the left and right top hooks 2 and 13 can be locked by the short distance movement of the push plate 17. The power consumption is lower each time the locking and unlocking of the tongue assembly 28 is lower, making it more energy-efficient.
