Description

Technical Field

[0001] This utility model relates to the field of door catch technology, and in particular to a self-locking door catch structure for large-area doors in factory buildings. Background Technology

[0002] Most traditional doorstops on the market, due to their fixed height and low installation position, are only suitable for installation on residential door panels. If traditional doorstops are to be installed in larger industrial plants or underground garage fire doors, the following drawbacks exist:

[0003] 1) Due to the large area and spaciousness of industrial plants, the wind speed at the factory entrance is relatively high. Traditional door suction on the market has weak suction, and the factory door panel is easily blown by the wind, which can easily lead to safety accidents for vehicles or personnel entering and leaving the factory.

[0004] 2) Fire doors in industrial plants or underground garages have large door panel areas and are installed high off the ground. Traditional door catches are installed low, and either the suction force is insufficient to hold the door in place, or the suction force is sufficient but the traditional door catch is a single point of force with a small force area, which can easily damage and deform the door panel, causing the upper part of the door frame to fall off and the door to deform and sink towards the door catch, resulting in property damage. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a self-locking door catch structure for large-area doors in factory buildings to overcome the deficiencies in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-locking door catch structure for a large-area factory door includes a lifting base installed and fixed on the floor or wall, and three sets of door catch components and one set of self-locking components installed on the lifting base; the door catch components and the self-locking components are both installed at the lower outer corner of the factory door panel, wherein the three sets of door catch components are installed at an angle with intervals, so that the three sets of door catch components and the lower outer corner of the door panel form a triangle.

[0008] The self-locking assembly includes a self-locking fixing component installed on the lifting seat and a self-locking following component installed on the door panel, wherein the self-locking fixing component and the self-locking following component are arranged in pairs;

[0009] The self-locking fixing component includes an L-shaped self-locking support set on the lifting seat. A clamping groove is vertically provided through the horizontal plate of the self-locking support, and a slotted locking throat is horizontally provided through the horizontal plate of the self-locking support. A hook plate is hinged in the clamping groove through a hinge shaft. A conical hook is provided on the top of the hook plate, and the hook plate is horizontally limited in the clamping groove by a torsion spring.

[0010] The self-locking follower component includes a locking rod corresponding to the slotted throat.

[0011] Furthermore, an L-shaped pedal is hinged to the lower end of the hook plate.

[0012] Furthermore, the door catch assembly includes a door catch fixing component disposed on the lifting base and a door catch following component correspondingly mounted on the door panel; the door catch fixing component and the door catch following component are arranged in pairs, and the door catch fixing component and the door catch following component are respectively equipped with magnetic components that can attract each other.

[0013] Furthermore, the lifting seat includes a base and a slide. The base is fixed to the floor or wall, and a groove is provided in the center of the base. The slide is slidably disposed in the groove.

[0014] Furthermore, a positioning bolt is provided through the side wall of the base.

[0015] Furthermore, the torsion spring is sleeved at both ends of the hinge shaft.

[0016] Furthermore, the locking rod is fixedly installed on the door side mounting bracket in a "U" shape via a connecting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1) The self-locking door catch structure for large-area doors in this case achieves the common door catch function through the door catch component and the self-locking function through the self-locking component. The three sets of door catch components are installed at intervals and diagonally at the lower outer corner of the door panel, so that the three sets of door catch components and the lower outer corner of the door panel form a triangle. Thus, the self-locking door catch structure of this case can achieve both the common door catch function and the self-locking function. In addition, the triangular installation position increases the force-bearing points of the door catch, solving the problem that the single-point force of traditional door catches easily leads to deformation and sinking of the door panel. It is suitable for installation in windy industrial factory environments, and can also achieve good adsorption and fixation effect for large-area door panels.

[0019] 2) The self-locking door catch structure for a large-area door in this case has both the door catch component and the self-locking component installed on a lifting base. The height of the lifting base is adjustable, so that the installation height of the components related to the door catch function and the self-locking function can be adjusted, which is convenient for fire door environments in industrial plants and underground garages with different height requirements.

[0031] Please see Figure 1-6 This utility model provides a self-locking door catch structure for a large area door in a factory, including a lifting base (1) installed and fixed on the floor or wall, and three sets of door catch components (2) and one set of self-locking components (3) set on the lifting base; the door catch components (2) and the self-locking components (3) are both installed at the lower outer corner of the factory door panel (4), wherein the three sets of door catch components (2) are installed at intervals and at an angle, so that the three sets of door catch components (2) and the lower outer corner of the door panel (4) form a triangle, thereby effectively solving the problem that the door panel is prone to deformation and sinking after the traditional door catch is subjected to single-point force.

[0032] The lifting seat (1) includes a base 11 and a slide 12. The base 11 is fixed to the floor or wall. A groove is provided in the center of the base 11, and the slide 12 is slidably disposed in the groove. A positioning bolt 13 is provided through the side wall of the base 11. When the positioning bolt 13 is tightened, the inner end of the positioning bolt 13 passes through the groove of the base 11 and abuts against the slide 12, thereby fixing the slide 12 at a certain height in the groove. Thus, the lifting height of the lifting seat (1) is adjustable to meet the high usage environment of the industrial plant door.

[0033] The door catch assembly (2) includes a door catch fixing member (21) mounted on a slide (12) of the lifting seat (1) and a door catch follower member (22) mounted on the door panel and moving with the door panel. The door catch fixing member (21) and the door catch follower member (22) are arranged in pairs, and the door catch fixing member (21) and the door catch follower member (22) are respectively equipped with magnetic components (200) that can attract each other, so that the door catch assembly (2) has the common door catch function.

[0034] Preferably, in this embodiment, the door catch fixing component (21) is also equipped with a reset spring that abuts against the magnetic component (200), so that the door catch fixing component (21) and the door catch follower component (22) have a certain buffering effect when they attract each other.

[0035] The self-locking component (3) includes a self-locking fixing member installed and fixed on the sliding seat (12) of the lifting seat (1) and a self-locking follower member correspondingly installed on the door panel and moving with the door panel. The self-locking fixing member and the self-locking follower member are arranged in pairs to achieve the self-locking function;

[0036] The self-locking fixing member includes an L-shaped self-locking support 31 fixedly erected on the sliding seat 12. A clamping groove 311 is vertically penetrated through the horizontal plate of the self-locking support 31, and a grooved throat 312 is horizontally penetrated through the horizontal plate of the self-locking support 31. A hook plate 314 is hinged in the clamping groove 311 through a hinge shaft 313. A conical hook 315 is arranged at the top of the hook plate 314. The hook plate 314 is horizontally limited in the clamping groove 311 by a torsion spring 316, and the torsion spring 316 is sleeved at both ends of the hinge shaft 313.

[0037] Further, an L-shaped pedal 317 is also hinged at the lower end of the hook plate 314. When the L-shaped pedal 317 is stepped on, the hook plate 314 deflects downward with the hinge shaft 313 as the axis. When the L-shaped pedal 317 is released, under the action of the torsion spring 316, the hook plate 314 resets to the horizontal position.

[0038] The self-locking follower member includes a lock rod 32 corresponding to the grooved throat 312. The lock rod 32 is fixedly installed on the door side mounting seat in a "U" shape through a connecting plate 33.

[0039] The principle of the self-locking fixing member and the self-locking follower member cooperating to complete self-locking is as follows:

[0040] Self-locking: When the door suction component is about to adsorb the door panel, the lock rod 32 pushes the conical hook 315 on the hook plate 314, causing the hook plate 314 to deflect downward, so that the lock rod 32 is stuck into the grooved throat 312. At this time, under the action of the torsion spring 316, the conical hook 315 resets and springs upward to hook the lock rod 32, achieving the self-locking effect;

[0041] Unlocking: When the L-shaped pedal 317 is stepped on, the hook plate 314 deflects downward with the hinge shaft 313 as the axis, and the conical hook 315 disengages from the lock rod 32. At this time, if the door panel is pulled open, the lock rod 32 disengages from the grooved throat 312, achieving the unlocking effect; then the L-shaped pedal 317 is released, and under the action of the torsion spring 316, the hook plate 314 and the conical hook 315 reset to the initial horizontal position.

[0042] Compared to existing technologies, the self-locking door catch structure for large factory doors in this case achieves the common door-catching function through door-catching components and the self-locking function through self-locking components. Three sets of door-catching components are installed at intervals and at an angle on the lower outer corner of the door panel, forming a triangle with the lower outer corner of the door panel. This allows the self-locking door catch structure to achieve both the common door-catching function and the self-locking function. Furthermore, the triangular installation position increases the force-bearing points of the door catch, solving the problem of traditional door catches easily deforming and sinking due to single-point force. It is suitable for installation in windy industrial factory environments and provides good adsorption and fixation for large door panels.

[0043] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
