Description

Technical Field

[0001] This utility model belongs to the field of anti-collision door technology, and specifically discloses an automatic closing anti-collision door. Background Technology

[0002] Currently, automatic closing crash barriers are widely used in warehousing, cold chain, and other industries. These barriers are purely mechanical in structure. When a logistics vehicle crashes through the barrier, it automatically returns and closes. However, existing automatic closing crash barriers suffer from drawbacks such as complex structure and slow return speed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic closing anti-collision door with a simple structure and fast return speed.

[0004] According to the technical solution provided by this utility model, the automatic closing anti-collision door includes a door frame, a door body, a pivot, a roller pivot, a roller, a spring tube, a compression spring, a bearing seat, a spring tube seat, and a spring tube seat cover. The door frame contains one or two door panels. A pivot is fixed at the bottom corner of each door panel, a roller shaft is fixed on the pivot, and a roller is installed on the roller shaft. A spring tube is fixed at the top corner of the door panel, with the upper end of the spring tube extending out of the door panel. The spring tube and the pivot are coaxial. A partition is fixed inside the spring tube, and a compression spring is installed inside the spring tube above the partition. The upper end of the compression spring extends out of the spring tube. At the bottom corner of the door frame, there are a number of bearing seats equal to the number of door bodies. Each bearing seat has a pivot hole. There are door body return slopes on the inner and outer sides of the bearing seat. The bottoms of the two door body return slopes intersect. The door body return slopes are spirally arranged around the pivot hole. The pivot is installed in the pivot hole, and the roller contacts the door body return slope. At the top corner of the door frame, a number of spring tube seats equal to the number of door panels are fixed. A spring tube seat cover is fixed to each spring tube seat. Both the spring tube seat and the spring tube seat cover are provided with spring tube mounting half holes. Two spring tube mounting half holes cooperate to form a spring tube mounting hole. The spring tube is inserted into the spring tube mounting hole, with a distance between the upper end of the spring tube and the inner bottom surface of the spring tube seat. The upper end of the compression spring abuts against the inner bottom surface of the spring tube seat.

[0005] Preferably, the rotating shaft is perpendicular to the roller shaft.

[0006] This invention has the advantages of simple structure, fast return speed and stable operation, making it very suitable as a cold chain warehouse door. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] An automatic closing anti-collision door, such as Figure 1-4 As shown, it includes a door frame 1, a door body 2, a pivot 2.1, a roller pivot 2.2, a roller 2.3, a spring tube 2.4, a compression spring 2.5, a bearing seat 3, a spring tube seat 4, and a spring tube seat cover 4.1; One or two door panels 2 are provided inside the door frame 1. A pivot 2.1 is fixed at the bottom corner of each door panel 2. A roller shaft 2.2 is fixed on the pivot 2.1. A roller 2.3 is installed on the roller shaft 2.2. A spring tube 2.4 is fixed at the top corner of the door panel 2. The upper end of the spring tube 2.4 extends out of the door panel 2. The spring tube 2.4 is coaxial with the pivot 2.1. A partition is fixed inside the spring tube 2.4. A compression spring 2.5 is installed inside the spring tube 2.4 above the partition. The upper end of the compression spring 2.5 extends out of the spring tube 2.4. At the bottom corner of the door frame 1, there are a number of bearing seats 3 equal to the number of door bodies 2. Each bearing seat 3 has a pivot hole 3.1. There are door body return slopes 3.2 on the inner and outer sides of the bearing seat 3. The bottoms of the two door body return slopes 3.2 intersect. The door body return slopes 3.2 are spirally arranged around the pivot hole 3.1. The pivot 2.1 is installed in the pivot hole 3.1, and the roller 2.3 contacts the door body return slope 3.2. At the top corner of the door frame 1, there are spring tube seats 4 in the same number as the door body 2. A spring tube seat cover 4.1 is fixed on each spring tube seat 4. Spring tube mounting half holes are provided on both the spring tube seat 4 and the spring tube seat cover 4.1. The two spring tube mounting half holes cooperate to form a spring tube mounting hole. The spring tube 2.4 is inserted into the spring tube mounting hole. The upper end of the spring tube 2.4 is spaced apart from the inner bottom surface of the spring tube seat 4. The upper end of the compression spring 2.5 abuts against the inner bottom surface of the spring tube seat 4.

[0013] The rotating shaft 2.1 is perpendicular to the roller shaft 2.2.

[0014] In actual use, when the logistics transfer vehicle contacts the door 2, the door 2 rotates forward around the axis of the pivot 2.1 and the spring tube 2.4. During the rotation, as the roller 2.3 contacts the door return slope 3.2, which is spirally raised around the pivot hole 3.1, the door 2 is gradually lifted against the elastic force of the compression spring 2.5 until the logistics transfer vehicle detaches from the door 2. At this point, the roller 2.3 moves to the top of the door return slope 3.2. After the logistics transfer vehicle detaches from the door 2, under the combined action of the gravity of the door 2 and the elastic force of the compression spring 2.5, the roller 2.3 slides down from the top of the door return slope 3.2, and the door 2 rotates in the opposite direction around the axis of the pivot 2.1 and the spring tube 2.4 until the roller 2.3 contacts the two door return slopes 3.2 on the axle seat 3. The door 2 then completes its automatic return, and the return action of the door 2 is fast and smooth.

[0015] In this utility model, the spring tube 2.4 can be quickly installed into the spring tube mounting hole by disassembling and assembling the spring tube seat cover 4.1.

[0016] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
