Description

Technical Field

[0001] The utility model relates to the technical field of ground hook locks, and in particular, to a ground hook lock structure. Background Art

[0002] With the development of rolling shutter doors, rolling shutter door technology is increasingly applied to some security technology places (such as prisons, supermarkets, banks, etc.). The door lock structure of rolling shutter doors in the existing structure is mostly provided with a ground lock structure to achieve anti-theft. The ground lock structure in the existing technology mostly includes a lock tongue arranged in a lock box, and a lock hook that can be hooked in the ground box through the lock tongue.

[0003] At present, most of the rolling door floor hook locks adopt a simple mechanical unlocking structure, that is, the lock tongue is displaced by turning the key to lock or release the lock hook. For example, the Chinese patent utility model CN209067031U provides a floor hook lock core structure, including a housing, a pull arm that moves under the drive of the key is arranged in the housing; and a limiter, the positioning member includes a limiter located between the pull arm and the side wall of the housing. The pull arm of the floor hook lock moves smoothly, the operation is labor-saving, and it is easy to pass the line, and it is easy to arrange electronic components in various parts of the floor hook lock.

[0004] However, the above-mentioned floor hook lock core structure still has the following disadvantages: in more important anti-theft door bodies, such as prisons and banks, when rolling shutter doors need to be raised and lowered quickly, the mechanical key alone has a slow unlocking speed, or there is a situation where the key is broken and stuck. In this way, the rolling shutter can be easily pulled and damaged when it is raised quickly, and electric unlocking must be assisted. However, the electric unlocking and mechanical unlocking structures affect each other, and setting up an electric unlocking structure alone will greatly increase the manufacturing cost of the floor hook lock structure.

[0005] Therefore, in order to solve the above problems, it is very necessary for us to design a reasonable and efficient ground hook lock structure. Utility Model Content

[0030] Embodiment 1: Figures 1 to 5 The figure is only one of the embodiments of the present invention, a ground hook lock structure, including a lock beam 4, an opening and closing part 3 arranged on the lock beam 4 and a driving part for driving the opening and closing part 3 to move, the driving part including a mechanical driving part 2 and an electric driving part 1, a lock column opening 41 is arranged on the lock beam 4, the opening and closing part 3 includes a first rotating plate 31 for connecting with the driving part and a second rotating plate 32 arranged at the lock column opening 41, the first rotating plate 31 is connected to the second rotating plate 32 through a first spring 34, the second rotating plate 32 is provided with a hook plate 322 for blocking the lock column opening 41, the mechanical driving part 2 includes a horizontal movable plate 21, the horizontal movable plate 21 is provided with an extension plate 22 for connecting with the first rotating plate 31; the electric driving part 1 includes a driving gear 11 and a driving handle 12 connected to the driving gear 11, and the driving handle 12 is provided with an extension column 121 for connecting with the first rotating plate 31.

[0031] In the utility model, the lock beam 4 is connected to the bottom beam of the rolling door, and a lock column opening 41 is provided on the lower side of the lock beam 4, and a lock column is provided horizontally on the ground of the rolling door. When the rolling door is lowered to the lower limit position, the lock column is located in the lock column opening 41 and is clamped by the opening and closing part 3 on the lock beam 4 to complete the locking of the rolling door; when the rolling door needs to be opened, the opening and closing part 3 on the lock beam 4 is driven by the driving part to release the lock column, and the rolling door can rise normally.

[0032] The key point is that the opening and closing of the opening and closing part 3 is to complete the locking and releasing of the lock column, and the opening and closing part 3 is driven by the driving part.

[0033] When the first rotating plate 31 is pushed forward and the second rotating plate 32 is pulled back, the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate 32 is pulled back and the second rotating plate

[0034] The driving unit includes a mechanical driving unit 2 and an electric driving unit 1, which are respectively as follows:

[0035] The mechanical driving part 2 should be a key driving part, and the mechanical driving part 2 includes a horizontal movable plate 21, and the horizontal movable plate 21 is provided with a protruding plate 22 for connecting with the first rotating plate 31; under the mechanical drive of the key, the horizontal movable plate 21 is driven to move horizontally, and the protruding plate 22 extending from the lower side of the horizontal movable plate 21 will contact the first rotating plate 31 and drive the first rotating plate 31 to rotate, thereby completing the unlocking of the ground hook lock;

[0036] Specifically, the lock beam 4 is provided with a mounting column 42 for connecting with the horizontal movable plate 21; the horizontal movable plate 21 is provided with a horizontal slide groove 23 for facilitating the sliding of the mounting column 42; the horizontal movable plate 21 is provided with a driving tooth 24, that is, the key is twisted to drive the gear engaged with the driving tooth 24 to rotate, thereby driving the horizontal movable plate 21 to move horizontally through the driving tooth 24. The horizontal movable plate 21 only moves horizontally under the limitation of the horizontal slide groove 23, so that the extending plate 22 drives the first rotating plate 31 to rotate to complete the hook lock unlocking.

[0037] The electric drive unit 1 includes a drive gear 11 and a drive handle 12 connected to the drive gear 11, and the drive handle 12 is provided with a protruding column 121 for connecting to the first rotating plate 31, and the protruding column 121 is arranged perpendicular to the drive handle; the electric drive unit 1 drives the drive gear 11 to rotate under the drive of the motor, thereby driving the drive handle 12 to slide in the electric drive unit 1, and the protruding column 121 at one end of the drive handle 12 away from the drive gear 11 will contact the first rotating plate 31 and drive the first rotating plate 31 to rotate, thereby completing the unlocking of the ground hook lock;

[0038] Specifically, the electric drive unit 1 also includes a screw 13 for meshing with the drive gear 11 and a drive motor 14 for driving the screw 13; the end of the drive handle 12 away from the protruding column 121 is connected to the drive gear 11 through a connecting column 122; the drive motor 14 drives the screw 13 to rotate, the screw 13 is tangential to the drive gear 11 and meshes with the drive gear 11, and the drive gear 11 and the screw 13 act as a connection of a worm gear mechanism, so that the high-speed rotation of the screw 13 is converted into a lower-speed rotation of the drive gear 11 (still much faster than the unlocking speed of the mechanical drive unit), thereby driving the drive handle 12 connected to the drive gear 11 through the connecting column 122 to displace, so that the protruding column 121 drives the first rotating plate 31 to rotate to complete the unlocking of the hook lock.

[0039] Of course, the extending column 121 and the extending plate 22 are both located on the same side of the first rotating plate 31, and the height of the extending column 121 is lower than that of the extending plate 22. Therefore, when the mechanical drive is unlocked, the horizontal displacement of the extending plate 22 does not cause the extension column 121 to move; similarly, when the electric drive is unlocked, the horizontal displacement of the extending column 121 does not cause the extension plate 22 to move, so that the mechanical drive unit 2 and the electric drive unit 1 can work independently without being affected.

[0040] In summary, in the present invention, the mechanical drive unit 2 and the electric drive unit 1 are independent of each other, but simultaneously drive a set of opening and closing units 3 to unlock the ground hook lock. The ground hook lock has various unlocking methods and good unlocking stability, and can be used for various rolling doors.

[0041] Embodiment 2, still as Figures 1 to 5 The figure is only one of the embodiments of the present invention. Based on the first embodiment, the present invention mainly describes the structure of the opening and closing part 3 in a ground hook lock structure:

[0042] The first rotating plate 31 is provided with a first rotating shaft 311 for connecting with the locking beam 4, and one end of the first rotating plate 31 away from the first rotating shaft 311 is provided with a functional convex plate 312 for connecting with the driving part, and the connection point between the first spring 34 and the first rotating plate 31 is provided between the first rotating shaft 311 and the functional convex plate 312;

[0043] The second rotating plate 32 is provided with a second rotating shaft 321 for connecting with the lock beam 4, and the connection point between the first spring 34 and the first rotating plate 31 is arranged on the side of the second rotating shaft 321 away from the hook plate 322; the second rotating shaft 321 is arranged on the side of the lock column opening 41 away from the first rotating plate 31.

[0044] by Figure 2 For example, when the extension plate 22 or the extension column 121 moves horizontally to the left, it will contact the functional convex plate 312, causing the first rotating plate 31 to rotate counterclockwise, thereby synchronously driving the second rotating plate 32 to rotate counterclockwise through the first spring 34, and the hook plate 322 rotates and releases from under the lock column, thereby completing the unlocking of the ground hook lock.

[0045] Embodiment three, still as Figures 1 to 5 The figure is only one embodiment of the present invention. Based on any of the above embodiments, in a ground hook lock structure of the present invention, the number of the mounting column 42 and the horizontal slide groove 23 are at least one, and the stability of the mechanical drive is better.

[0046] In the utility model, the driving motor 14, the screw 13, the driving handle 12 and the driving gear 11 are all installed in the box body 15; the box body 15 is provided with a first limiting groove 151 for limiting the sliding of the driving handle 12 and a second limiting groove 152 for limiting the sliding of the extending column 121. The driving handle 12 is a crank structure. The driving handle 12 is displaced under the rotation of the driving gear 11. The driving handle 12 is limited by the displacement of the first limiting groove 151, and the extending column 121 is limited by the displacement of the second limiting groove 152, so that the driving gear 11 is driven to rotate and the driving handle 12 is displaced horizontally.

[0047] In addition, the opening and closing portion 3 also includes a third rotating plate 33, the first rotating plate 31 is connected to the third rotating plate 33 through a second spring 35, and an extension column 332 is provided on the third rotating plate 33; the driving gear 11 is provided with an arc groove 111 for facilitating the sliding of the extension column 332; the first rotating plate 31 is provided with a limit plate 313 extending toward the third rotating plate 33; the third rotating plate 33 is provided with a connecting plate 333 for connecting with the limit plate 313.

[0048] The third rotating plate 33 mainly serves to limit the first rotating plate 31 , so that when the first rotating plate 31 is rotated clockwise to return to its original position, the limiting plate 313 is just mounted on the connecting plate 333 .

[0049] The extension column 332 is arranged perpendicular to the third rotating plate 33 and extends to the arc groove 111 of the driving gear 11. When the driving gear 11 rotates, the extension column 332 slides in the arc groove 111 until the extension column 332 contacts the end of the arc groove 111. At this time, the driving gear 11 continues to rotate to drive the third rotating plate 33 to rotate counterclockwise, and the connecting plate 333 releases the limiting plate 313; on the contrary, when the driving gear 11 does not rotate and only mechanical drive is performed, when the extension plate 22 drives the first rotating plate 31 to rotate, the third rotating plate 33 is driven to rotate through the second spring 35. At this time, the extension column 332 can just slide in the arc groove 111, and the rotation of the third rotating plate 33 and the first rotating plate 31 is also limited by the end of the arc groove 111.

[0050] Here, the third rotating plate 33 is provided with a third rotating shaft 331 for connecting with the locking beam 4, and the extension column 332 and the connecting plate 333 are both arranged on the side of the third rotating shaft 331 away from the connection point between the second spring 35 and the third rotating plate 33; the connection point between the second spring 35 and the first rotating plate 31 is located between the first rotating shaft 311 and the functional convex plate 312.

[0051] The utility model discloses a ground hook lock structure, which connects two sets of drive structures, a mechanical drive part and an electric drive part, on the same set of opening and closing structure, so as to ensure that the mechanical unlocking and the electric unlocking are independent of each other, thereby ensuring stable unlocking, and has low production cost, and is applicable to unlocking a variety of rolling shutter doors.

[0052] The present invention is not limited to the above specific implementation modes, and the present invention can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementation modes based on the technical essence of the present invention shall be included in the protection scope of the present invention.
