DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-6The utility model provides a technical solution: a rolling door ground lock, comprising a lock plug 6 fixedly connected to the bottom beam of the rolling door and an underground lock box 1, the upper end of the underground lock box 1 is arranged at the socket, and a cover plate 2 is hinged on the upper end of the underground lock box 1, which is used to cover the socket to prevent foreign objects from entering the underground lock box and affecting the appearance, an elastic member 3 is connected between the cover plate 2 and the inner wall of the underground lock box 1, and an axle rod is connected between the cover plate 2 and the inner wall of the underground lock box 1, the elastic member 3 is a torsion spring, and the torsion spring is sleeved on the outer wall of the axle rod, and an abutment block is fixedly connected to the inner wall of the underground lock box 1, one end of the torsion spring abuts against the bottom of the cover plate 2, and the other end of the torsion spring abuts against the abutment block, so that the cover plate 2 can always block the socket at the upper end of the underground lock box 1 when it is in a normal state.
[0028] A folding support assembly connected to the bottom of the underground lock box 1 is provided at the lower end of the cover plate 2, which is used to support the cover plate 2. While the elastic force of the elastic member 3 drives the cover plate 2 upward to block the socket, the cover plate 2 can provide an upward force to the folding support assembly, so that the folding support assembly has the function of supporting the cover plate 2. A top-pull assembly connected to the folding support assembly is also provided at the lower end of the cover plate 2. The top-pull assembly can maintain the supporting state of the folding support assembly to prevent rod-shaped objects such as the heels of high-heeled shoes from sinking into the underground lock box and causing danger.
[0029] The lock plug 6 is provided with a driving unit for releasing the support of the folding support assembly for the cover plate 2. The driving unit is magnetically connected to the top-pull assembly. When the rolling door is closed, the lock plug 6 will move downward. The driving unit can drive the folding support assembly to release the support for the cover plate 2 by being magnetically connected to the top-pull assembly, making it convenient for the lock plug 6 to be inserted into the underground lock box 1 to lock the rolling door.
[0030] Specifically, the driving unit includes a first permanent magnet 7 arranged at the lower end of the lock plug 6, and the top-pull assembly includes a second permanent magnet 54. The second permanent magnet 54 is arranged corresponding to the first permanent magnet 7, and the second permanent magnet 54 and the first permanent magnet 7 are arranged opposite to each other at different levels. When the rolling door is closed, the lock plug 6 will be driven to move downward. When the first permanent magnet 7 at the lower end of the lock plug 6 gradually approaches the second permanent magnet 54, it will attract the second permanent magnet 54 to make the second permanent magnet 54 rise. The second permanent magnet 54 can be conducted through the top-pull assembly, which can enable the folding support assembly to release the support for the cover plate 2, making it convenient for the lock plug 6 to be inserted into the buried lock box 1 to lock the rolling door.
[0031] Specifically, the folding support assembly includes a support plate 41 hinged to the cover plate 2, and a base plate 42 is hinged at the bottom of the buried lock box 1. The ends of the support plate 41 and the base plate 42 that are close to each other are both flat. When supporting the cover plate 2, the two surfaces are in contact, making the folding support assembly more stable. The support plate 41 is connected to the top-pull assembly, and the support plate 41 and the side wall of the base plate 42 away from the top-pull assembly are jointly installed with a hinge 43. The maximum flip angle of the hinge 43 is 180 degrees. When the lock plug 6 moves downward, the support plate 41 will be driven to move through the top-pull assembly, so that the support plate 41 rotates around the hinge point between the support plate 41 and the cover plate 2, thereby driving the base plate 42 to rotate, thereby releasing the support of the cover plate 2 by the folding support assembly.
[0032] Specifically, a sliding hole is provided at the bottom of the lock plug 6, and the driving unit also includes a buffer block 9 sliding in the sliding hole. The first permanent magnet 7 is installed in the buffer block 9, and a buffer member 11 is provided between the buffer block 9 and the bottom of the sliding hole. The buffer member can be a compression spring or a buffer to prevent the second permanent magnet 54 from rising to a insufficient height at the moment when the lock plug 6 contacts the cover plate 2, that is, when the folding support assembly has not yet released the support for the cover plate 2, the rolling shutter door drives the lock plug 6 to be pressed down, which will damage the cover plate 2 or cause damage to the motor of the rolling shutter door.
[0033] Specifically, the top-pull assembly also includes an optical axis 51 fixedly connected to the cover plate 2, and a counterweight plate 52 is slidably sleeved on the outer wall of the optical axis 51. The second permanent magnet 54 is arranged at the upper end of the counterweight plate 52. Under normal conditions (when the first permanent magnet 7 does not attract the second permanent magnet 54), the counterweight plate 52 always has a downward force under the action of gravity, and the lower end of the counterweight plate 52 is hinged with a connecting rod 53 hinged to the support plate 41. The counterweight plate 52 will support the connecting rod 53, and then support the support plate 41, thereby maintaining the support state of the cover plate 2, preventing the base plate 42 and the support plate 41 from accidentally rotating, causing the folding support assembly to lose its supporting function.
[0034] Specifically, the end of the connecting rod 53 located on the support plate 41 is lower than the end of the connecting rod 53 located on the counterweight plate 52 , so that the counterweight plate 52 can support the support plate 41 under the action of gravity.
[0035] Specifically, a baffle plate 8 is fixedly connected to the bottom of the optical axis 51 to limit the counterweight plate 52 .
[0036] Specifically, a limiting block is fixed in the sliding hole, and a protrusion is fixed to the side of the buffer block 9 to limit the buffer block 9.
[0037] Working principle:
[0038] When in use, the elastic force of the elastic member 3 can enable the cover plate 2 to always maintain the force of upward rotation, driving the support plate 41 and the base plate 42 to be in a vertical state. The ends of the support plate 41 and the base plate 42 that are close to each other are both flat. When supporting the cover plate 2, the two surfaces are in contact, making the folding support assembly support the cover plate 2 more stably.
[0039] The counterweight plate 52 always has a downward force under the action of gravity. The counterweight plate 52 will support the connecting rod 53, and then apply a force to the support plate 41 to push the hinge 43, so as to support the support plate 41, so that the support plate 41 and the base plate 42 maintain a supporting state for the cover plate 2, and prevent the base plate 42 and the support plate 41 from accidentally rotating, causing the folding support assembly to lose its supporting function.
[0040] When the rolling door is closed, the lock plug 6 will be driven to move downward. When the bottom of the lock plug 6 contacts the cover plate 2, the first permanent magnet 7 will attract the second permanent magnet 54, causing the second permanent magnet 54 to rise. The second permanent magnet 54 will drive the counterweight plate 52 to rise, and then drive the support plate 41 and the base plate 42 to rotate and fold through the connecting rod 53 to release the support for the cover plate 2, making it convenient for the lock plug 6 to be inserted into the buried lock box 1 to lock the rolling door.
[0041] When the bottom of the lock plug 6 contacts the cover plate 2, the buffer member 11 is provided to prevent the second permanent magnet 54 from rising insufficiently at the moment the lock plug 6 contacts the cover plate 2, that is, when the folding support assembly has not yet released the support for the cover plate 2, the rolling door drives the lock plug 6 downward to damage the cover plate 2 or cause damage to the motor of the rolling door.
