Windproof rolling gate seal

Abstract

The utility model discloses a wind-proof rolling gate seal which comprises a rolling gate seal head, a wind-resistant hook is arranged on the upper surface of a seal head blocking piece, and the wind-resistant hook and the seal head blocking piece are integrally formed. The wind-resistant hook extends outwards by a certain length in the width direction of the end socket blocking piece to form an overhanging hook body structure. When the front face of the rolling gate is subjected to strong wind, the rolling gate can sink inwards, and at the moment, the wind-resistant hook can hook the sliding groove in the door frame to provide restraining force for the rolling gate so as to prevent the rolling gate from falling off.

Description

Technical Field

[0001] The utility model relates to a sealing structure of a rolling shutter door. Background Art

[0002] Rolling shutter doors are generally quite wide and will bear greater pressure when encountering strong winds. In addition, the rigidity of rolling shutter doors is relatively poor. The rolling shutter doors are restricted by the sliding grooves of the door frame. When the wind force is insufficient to fix the rolling shutter door, the door frame will not be able to hold the rolling shutter door in place. At this time, the rolling shutter door will shift or even derail, causing damage to the rolling shutter door. In order to enhance the wind resistance, a structure can be added to the door frame to improve the restraint effect on the rolling shutter door. For example, Chinese patent CN215804271U discloses a windproof rolling shutter door. This utility model extends a slider structure outside the rolling shutter door head, adds an inner track to the track of the door frame, and adds a baffle to clamp the neck between the head and the slider to achieve the restraint of the rolling shutter door. The disadvantage of this structure is that the connection part (neck) between the head and the slider is relatively weak and may break, and it requires a larger increase in the door frame depth and head size. The restraint ability between the spherical slider and the baffle is also relatively weak. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that a windproof structure with a strengthened structure is provided to solve the problem that the existing windproof structure of a rolling shutter door has weak links that are easy to break or fall off.

[0004] The technical solution of the utility model is: a windproof rolling shutter door seal, comprising a rolling shutter door sealing head, and a windproof hook is arranged on the upper surface of the sealing head blocking piece.

[0005] The wind-resistant hook and the head plug are integrally formed. The wind-resistant hook extends outwards for a certain length along the width direction of the head plug to form a cantilevered hook structure.

[0006] The head plugging piece is a three-staggered structure, including a lower plugging piece at the lower layer, an upper plugging piece at the middle layer and a wind-resistant hook at the upper layer. The lower plugging piece and the upper plugging piece are staggered in the length direction, forming an upper and lower staggered structure at both ends of the length direction, and the wind-resistant hook and the upper plugging piece are staggered in the width direction, forming a downward staggered structure in the width direction.

[0007] The upper surface of the wind-resistant hook is chamfered.

[0008] The bottom of the head plug is connected to the socket, and both ends of the head plug are perforated. Windproof hook limiting grooves are opened in the slide grooves on both sides of the rolling shutter door, and the windproof hook limiting grooves are arranged on the inner wall surface of the slide groove close to the door outside.

[0009] The beneficial effects of the present invention are:

[0010] When the front of the rolling shutter door is affected by strong winds, it will concave inward. At this time, the wind-resistant hook will hook the sliding groove in the door frame, providing restraint for the rolling shutter door and preventing it from falling off.

[0011] The wind-resistant hook and the sealing of the rolling shutter door are integrally injection-molded. The connection is thick and not easy to break. The overall length does not need to be increased too much, and the depth of the sliding groove in the door frame should not be increased too much. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below with reference to the accompanying drawings and specific embodiments:

[0017] Example:

[0018] like Figure 2-Figure 4 This is a 3D rendering of a rolling shutter door head. The main improvement is a wind-resistant hook on the upper surface of the head plug. The hook and the head plug are integrally formed, and the hook extends outward along the width of the head plug to form a cantilevered hook structure.

[0019] The head plug has a three-layer staggered structure, consisting of a lower plug, an upper plug, and a wind-resistant hook. The lower and upper plugs are staggered in length, forming an up-down staggered structure at both ends. The wind-resistant hook and upper plug are staggered in width, forming a downward staggered structure. The bottom of the head plug is connected to a socket, which has holes at both ends. The socket is inserted into the side of the shutter door and screwed in.

[0020] Furthermore, the surface of the wind-resistant hook is chamfered to make it more rounded as a whole and easier to install.

[0021] To enhance the restraining force of the wind-resistant hooks, the rolling shutter's chute structure requires structural improvements. Wind-resistant hook stop slots are installed on both sides of the chute. These stop slots are located on the inner wall of the chute, near the outside of the door. This allows the wind-resistant hooks to press against the stop slots when the door is subjected to pressure from the front, preventing further bending. Because there's no wind inside the closed door, there's no need for a special reverse wind-resistant structure.
