Description

Technical Field

[0001] This utility model belongs to the technical field of sealing brushes for roller shutter doors, specifically a sealing brush that acts on the cover of a roller shutter door. Background Technology

[0002] As a common protective facility at building entrances, the airtightness of roller shutter doors is crucial to their performance and lifespan. In practical applications, dust, rainwater, insects, and other external environmental factors can easily penetrate through the gaps between the roller shutter door shell and the door body and track. This not only accelerates the wear and tear on components such as the shutter slats and rollers but can also affect the normal operation of the mechanical transmission system, increasing the frequency of malfunctions and maintenance costs. Furthermore, roller shutter doors lacking effective sealing perform poorly in terms of sound and heat insulation, making it difficult to meet the energy-saving and noise-reduction requirements of modern buildings.

[0003] Traditional sealing brushes are typically fixed directly to the roller shutter door housing, usually using adhesive or screws. Adhesive bonding is susceptible to changes in temperature and humidity, and tends to detach after prolonged use; furthermore, cleaning residual adhesive during replacement is cumbersome. While screw fastening is relatively secure, the process requires various tools and is time-consuming, making it inefficient for maintenance and replacement, and failing to meet the needs of rapid repair. Therefore, we propose a sealing brush designed for use on the roller shutter door housing. Utility Model Content

[0004] The purpose of this invention is to provide a sealing brush that acts on the roller shutter door cover to solve the problems mentioned in the background art.

A slot is provided on the rear side of the connecting plate 11, and a rubber strip 131 is engaged in the slot. Brush bristles 13 are evenly fixedly arranged on the rear side of the rubber strip 131. Two sets of rubber positioning posts 132 are evenly fixedly arranged on the front side of the rubber strip 131. Pins 122 are inserted between the rubber positioning posts 132 and the connecting plate 11 and the support frame 1. A set of [unclear text - possibly a type of pin] is fixedly arranged on the opposite sides of each set of pins 122. A high-strength spring 124 is used. A set of magnets 123 are embedded on the opposite sides of both sets of pins 122. A connecting block 121 is fixedly installed on the front side of each pin 122, and a lever 12 is fixedly installed on the front side of the connecting block 121. Locking slots are provided on both the left and right sides of the inner wall of the support frame 1. The side of the pin 122 away from the high-strength spring 124 is inserted into the locking slot, and the magnets 123 are magnetically attracted to the locking slot. The high-strength spring 124 drives the pin 122 to insert into the locking slot of the support frame 1, cooperating with the magnets 123. The magnetic attraction of pin 122 allows it to be stably inserted into the locking groove, thereby locking the connecting plate 11 into the support frame 1. Two sets of first sliding grooves are evenly distributed on the front side of the connecting plate 11, and a set of second sliding grooves are distributed on both the left and right sides of the connecting plate 11. A third sliding groove connects the first and second sliding grooves. A through hole connects the second sliding groove and the slot. A locking hole is formed through the right side of the rubber positioning post 132. The through hole on the front side of the rubber positioning post 132 is located within the second sliding groove. The locking hole connects with the second... The slides are connected, the push block 12 is slidably disposed in the first slide, the connecting block 121 is slidably disposed in the third slide, the pin 122 is slidably disposed in the second slide, and the high-strength spring 124 is fixedly disposed in the second slide. The pin 122 passes through the locking hole of the rubber positioning post 132, and engages the rubber clip 131 in the slot of the connecting plate 11, and inserts the rubber positioning post 132 into the through hole of the connecting plate 11, so that the bristles 13 are initially engaged and fixed on the outside of the connecting plate 11 by the rubber clip 131.

[0021] A clearance groove is provided through the bottom of the inner sidewall of the support frame 1, and countersunk holes are uniformly provided through the top of the inner sidewall of the support frame 1. Through holes corresponding to the countersunk holes are uniformly provided at the bottom of the roller shutter cover. Then, the support frame 1 is placed at the bottom of the roller shutter cover. Then, the head of the rivet gun equipped with rivets is inserted into the support frame 1 through the clearance groove, and the rivets pass through the countersunk holes and the through holes on the roller shutter cover. Then, the rivet gun can rivet the support frame 1 to the bottom of the roller shutter cover through the rivets. A sealing gasket 125 is fixedly provided on the rear side of the lever 12. The outer side of the sealing gasket 125 is in contact with the inner side of the first sliding groove. The sealing gasket 125 seals the connection gap between the lever 12 and the first sliding groove.

[0022] Working principle: Through holes corresponding to the countersunk holes are evenly opened at the bottom of the roller shutter cover. Then, the support frame 1 is placed at the bottom of the roller shutter cover. The head of a rivet gun equipped with rivets is then inserted into the support frame 1 through the clearance groove, allowing the rivets to pass through the countersunk holes and the through holes on the roller shutter cover. The rivet gun then rivets the support frame 1 to the bottom of the roller shutter cover using the rivets. The inward-moving lever 12 moves the pin 122 inward through the connecting block 121. Then, the rubber clip 131 is engaged in the slot of the connecting plate 11, and the rubber positioning post 132 is inserted into the through hole of the connecting plate 11, thereby allowing the bristles 13 to pass through the rubber... The rubber clip 131 is initially snapped and fixed to the outside of the connecting plate 11. Then, the connecting plate 11 is inserted into the support frame 1. At this time, the lever 12 is released, and the high-strength spring 124 uses its own rebound force to push the pin 122 through the locking hole of the rubber positioning post 132 and insert it into the locking groove of the support frame 1. With the magnetic attraction of the magnetic block 123, the pin 122 is stably inserted into the locking groove. In this way, the rubber positioning post 132 can be locked in the through hole of the connecting plate 11 by the pin 122, thereby further ensuring the connection stability between the bristles 13 and the connecting plate 11, and also locking the connecting plate 11 in the support frame 1.

[0023] When the bristles 13 become worn and unusable due to prolonged friction with the roller shutter door, the connecting block 12 is moved inward to drive the connecting block 121, causing the pin 122 to move inward and separate from the support frame 1 and the rubber positioning post 132. Then, the connecting plate 11 can be moved forward and pulled out from the support frame 1. The bristles 13, along with the rubber clip 131 and the rubber positioning post 132, can then be pulled out from the connecting plate 11 for replacement.
