Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, and more specifically to a roller shutter door winding track. Background Technology

[0002] Roller shutters, also known as rolling doors or roller shutters, are a common type of door facility widely used in shops, garages, warehouses, and other places. Their main feature is that the door can be rolled up or down electrically or manually to achieve the function of opening and closing the door. They not only have good anti-theft performance, but are also very efficient in space utilization, as they take up almost no extra space when open. As shown in the existing roller shutter door, "as described in application number: CN202210978917.3, a roller shutter door with an emergency stop function and its stopping method", a guide component (i.e., a winding track) for the rolling shutter to be rolled up and down is proposed. When the roller shutter is rolled up, the roller shutter moves in the guide component. During the movement, an electric drive mechanism is generally required to drive it. When stopping, the inertia generated means that the braking is triggered by the drive mechanism alone. This has the disadvantage of lacking buffer protection and reducing the service life of the drive mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a winding track for roller shutter doors in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a rewinding track for a roller shutter door, including a track body; It also includes a protective device installed at the end of the main track winding mechanism; The protective device includes a sleeve fixed to the winding end of the track body and a buffer block fixed inside the sleeve. The buffer block extends into the main body of the track, and the buffer block is made of a pressure-deformed and resilient material.

[0005] As a preferred embodiment of this utility model, the compressive deformation rebound material is rubber or thermoplastic polyurethane elastomer.

[0006] As a preferred embodiment of the present invention, the protective device further includes a disassembly and assembly assembly fixed between the track body and the housing.

[0007] As a preferred technical solution of this utility model, the disassembly and assembly assembly includes a slot at the winding end of the track body, an insert block fixed to the outside of the housing, and a bolt. The slot allows the insert block to extend into and fit, and the bolt is threaded through the slot and the insert block on the outside of the track body.

[0008] As a preferred embodiment of the present invention, the protective device further includes a movement aid component fixed inside the casing and between the buffer block.

[0009] As a preferred technical solution of this utility model, the moving aid component includes a ring plate fixed to the outer part of the buffer block, universal balls fixed to the outer side of the ring plate, and a ball groove provided in the housing, wherein the universal balls roll in close contact within the ball groove.

[0010] As a preferred embodiment of the present invention, the protective device further includes a spring sleeved outside the buffer block. The buffer block has an annular groove around its periphery and the spring is located within the annular groove. The two elastic ends of the spring are fixed to the sleeve and the annular groove, respectively.

[0011] The beneficial effects of this utility model are as follows: By installing a protective device at the end of the main winding of the track, when the roller shutter is rolled up, the roller shutter contacts the buffer block in the middle. The flexible deformation of the buffer block supports the reduction of the inertia when the roller shutter stops, reducing the impact and improving the protection of the drive mechanism. The disassembly and assembly components are used to facilitate overall disassembly. The movement assist component is used to provide displacement stability when the buffer block is compressed. The spring provides a rebound assist effect when the buffer block is compressed and deformed, thereby improving the stability of the original shape. Attached Figure Description

Detailed Implementation

[0014] like Figure 1 As shown, this utility model proposes: a rewinding track for a roller shutter door, including a track body A, which provides support and guidance for the roller shutter door during its rewinding and unwinding activities; It also includes a protective device B installed at the winding end of the main track body A; The protective device B includes a housing 1 fixed to the winding end of the track body A and a buffer block 2 fixed inside the housing 1; the housing 1 may be made of stainless steel. The buffer block 2 extends into the interior of the main track body A. The buffer block 2 is made of a pressure-deformed and spring-rebound material.

[0015] Track body A winding end position as follows Figure 1As shown, a fixed sleeve 1 is installed at the winding end of the track body A to stabilize the position of the buffer block 2. A part of the buffer block 2 extends into the winding end of the track body A. When the roller shutter rolls up, it contacts the buffer block 2. The flexible deformation of the buffer block 2 reduces the inertia of the roller shutter when it stops, reduces the impact, and improves the protection of the drive mechanism.

[0016] Among them, the compressive deformation rebound material is rubber or thermoplastic polyurethane elastomer, which has good resilience and high durability.

[0017] Based on the above, further: The protective device B also includes a disassembly and assembly assembly 3 fixed between the track body A and the housing 1, which is used for the disassembly and assembly of the entire protective device B. Specifically: The disassembly and assembly component 3 includes a slot 31 located at the winding end of the track body A, an insert 32 fixed to the outside of the housing 1, and a bolt 33. The slot 31 allows the insert 32 to extend into and fit, and the bolt 33 is threaded through both the slot 31 and the insert 32 on the outside of the track body A. A slot 31 is pre-cut at the winding end of the track body A, and a fixing block 32 is fixed on the outside of the casing 1. When the fixing block 32 is inserted into the slot 31, the winding end of the track body A and the casing 1 fit together and support each other, and the inner side of the track body A is connected to the inside of the casing 1. A threaded hole is provided on the outside of the track body A to pass through the slot 31. The threaded hole passes through both sides of the fixing block 32. The fixing block 32 is then secured by bolts 33 passing through the threaded hole. The assembly is completed, and the operation is simple.

[0018] Based on the above, further: Protective device B also includes a displacement aid component 4 fixed inside the housing 1 and between the buffer block 2; used to provide displacement stability for the deformation of the buffer block 2 when it is compressed; Specifically: the moving aid assembly 4 includes a ring plate 41 fixed to the outer part of the buffer block 2, universal balls 42 fixed to the outer side of the ring plate 41, and a ball groove 43 provided in the housing 1. The universal balls 42 roll in the ball groove 43. The ring plate 41 can be made of stainless steel. A ring plate 41 is attached and fixed to a portion of the outer periphery of the buffer block 2. Multiple sets of universal balls 42 are evenly installed on the outer periphery of the ring plate 41, and multiple ball grooves 43 are evenly arranged inside the housing 1 to allow the multiple sets of universal balls 42 to fit and move, thereby improving the stability of the movement. At this time, both the housing 1 and the buffer block 2 are arc-shaped, which can better bear the deformation and shrinkage of the buffer block 2 after being subjected to force.

[0019] Based on the above, further: The protective device B also includes a spring 5 sleeved on the outside of the buffer block 2. The buffer block 2 has an annular groove on its periphery and the spring 5 is located in the annular groove. The two elastic ends of the spring 5 are fixed to the sleeve 1 and the annular groove, respectively. The spring 5 is a cylindrical helical elastic spring. like Figure 1 As shown, an annular groove is provided around the buffer block 2, which is far from the winding end of the main track A. The upper and lower elastic ends of the spring 5 are welded to the housing 1 and bonded to the annular groove, respectively. This provides a rebound assist effect to improve the stability of the original shape when the buffer block 2 is compressed and deformed.
