Description

Technical Field

[0001] The present invention belongs to the technical field of gates, and particularly relates to a flexible gate. Background Art

[0002] Existing gates are all rigid gates, that is, the gate panels are rigid. The gates are divided into upward-opening or downward-opening types. The opening and closing of the gates require the space of two gate panels, resulting in the outer dimension of the gate being larger than the space of the two gate panels. However, in many current occasions, the installation space of the gate is limited, or the construction cost is relatively high due to the overly large installation space of the gate. In addition, the sealing performance of rigid gates is poor, and it is necessary to install water-stop components on the door frame for auxiliary sealing. However, the installation and maintenance of the water-stop components are cumbersome and need to be frequently replaced, undoubtedly increasing the construction and use costs of the gate. Summary of the Invention

[0003] Object of the Invention: Aiming at the deficiencies of the existing technology, the object of the present invention is to provide a flexible gate with small occupied space, good sealing performance and low cost.

[0004] Technical Solution: In order to achieve the above object of the invention, the technical solution adopted by the present invention is as follows:

[0005] A flexible gate includes a door frame structure, a gate chamber structure and a gate panel. The gate panel is a flexible structure. The door frame structure and the gate chamber structure are provided with chutes, and the gate panel is slidably installed in the chutes; when the gate is in the open state, the gate panel is in a curled or folded state and is received in the gate chamber structure, and when the gate is in the closed state, the gate panel is in an unfolded state and fits with the door frame structure in a sealed manner to form a sealing structure.

[0006] Preferably, the gate panel is made of a flexible material that can be curled or folded, and the flexible material is rubber.

[0007] Preferably, a plurality of gate panel skeletons are arranged inside the gate panel, and multiple gate panel skeletons are arranged in parallel and are covered by the flexible material.

[0008] Preferably, rollers are arranged on both sides of the gate panel. The flexible gate is provided with a sliding structure, and the sliding structure includes rollers arranged on both sides of the gate panel, a door frame roller track arranged between the door frame structures, and a gate chamber roller track arranged inside the gate chamber structure. The rollers move along the door frame roller track and the gate chamber roller track.

[0009] Preferably, the door frame roller track is a straight track, and the gate chamber roller track is a curled track.

[0010] Preferably, the spacing distance between the door panel skeletons and the size of the door panel skeletons are set according to the curvature of the roller track of the door storage.

[0011] Preferably, the flexible gate further includes a driving mechanism, which is connected to the door panel through a transmission mechanism. When the driving mechanism is started forward, the door panel is unfolded through the transmission mechanism. When the driving mechanism is started backward, the door panel is curled or folded through the transmission mechanism.

[0012] Preferably, the driving mechanism includes a driving motor and a transmission shaft. The transmission mechanism is a chain transmission mechanism. The door panel is connected to the chain transmission mechanism, and the chain transmission mechanism is in transmission connection with the transmission shaft. The door panel is connected to the transmission mechanism through a connecting block.

[0013] Preferably, the door panel is provided with an associated structure for enhancing the strength of the door panel, and the associated structure is a wire mesh or fiber.

[0014] Preferably, the thickness of the door panel is greater than the width of the sliding groove. When the door panel slides in the sliding groove, an interference fit is formed between the door panel and the sliding groove.

[0015] Advantages: Compared with the prior art, the present invention has the following advantages:

[0016] (1) The flexible gate of the present invention adopts a flexible door panel made of rubber material. The flexible door panel can be curled or folded up when in the open state. A door storage structure is provided at the lower end of the door frame. The door storage structure is a storage mechanism for the door panel when the gate is opened. A curved track is provided in the door storage, and the door panel moves along the direction of the track to achieve bending and folding, greatly saving space, making the size and volume of the entire gate greatly reduced, and reducing the space occupation and construction cost.

[0017] (2) A door panel skeleton is arranged inside the door panel. The skeleton can be made of materials with relatively light weight and high strength such as aluminum alloy sections, which can reduce the weight of the door panel while ensuring strength. The parallel and spaced-apart door panel skeletons can ensure a certain flexibility of the door panel while ensuring strength.

[0018] (3) When the gate of the present invention is in the closed state, since the door panel itself is made of a flexible material such as rubber, an interference fit is formed between it and the sliding groove of the door frame structure. The elasticity of the flexible material itself absorbs the gap between it and the sliding groove, enabling the door panel to fit with the sliding groove to form a sealing structure when in the closed state. The sealing performance is good, and there is no need to separately set a sealing member, which is convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following further clarifies the present invention in conjunction with specific embodiments. The embodiments are implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0028] As Figure 1-8 shown, the flexible gate of the present invention mainly includes a door frame structure, a door storage structure, a door panel 1, a driving mechanism and a transmission mechanism. The door frame structure is the associated structure of the entire gate. The door panel 1, the driving mechanism and the transmission structure are all installed on the door frame structure. The door frame structure and the door storage structure are provided with sliding grooves, and the door panel 1 is slidably installed in the sliding grooves. The door storage structure is arranged at the lower part of the door frame structure and is seamlessly connected to the door frame structure. The door storage structure is the space where the door panel 1 curls or folds when the gate is in the open state. The door panel 1 is a flexible structure. When the door panel 1 is in the open state, it can curl or fold into the door storage structure. When in the closed state, it can be unfolded to fit the sealing surface of the door frame structure to form a sealing structure. The door panel unfolds and curls through the driving mechanism and the transmission mechanism.

[0029] The door frame structure is composed of door frame section steel 2 and a steel plate covering the outside of the door frame section steel 2. The door frame section steel 2 is a skeleton structure, and the outer covering steel plate serves as the protective door frame shell 3. The door frame section steel 2 includes an entrance door frame section steel 21 and an exit door frame section steel 22. The entrance door frame section steel 21 and the exit door frame section steel 22 jointly form a chute, and the door panel 1 is arranged between the entrance door frame section steel 21 and the exit door frame section steel 22, that is, arranged in the chute. A door frame roller track 4 is also fixedly arranged in the door frame section steel 2. The door frame roller track 4 is linear, and the rollers 5 on the door panel 1 roll in the door frame roller track 4, so that the door panel 1 moves along the direction of the door frame roller track 4.

[0030] The driving mechanism includes a driving motor 6, a speed reducer 7, a coupling 8, a transmission shaft 9, a bearing block 10, etc. The driving mechanism is fixedly arranged at the upper end of the door frame structure. The driving motor 6 is connected to the speed reducer 7. The output shafts at both ends of the speed reducer 7 are respectively connected with a transmission shaft 9 through a coupling 8. The driving motor 6 drives the speed reducer 7 to rotate, drives the transmission shafts 9 on both sides to rotate through the coupling 8, and the bearing block 10 is fixed at the upper end of the door frame structure to support the transmission shaft 9. A driving box 20 is arranged outside the driving mechanism to protect the driving mechanism. An openable movable cover 23 is arranged at the upper end of the driving box 20 to facilitate the maintenance of the driving mechanism.

[0031] The transmission mechanism adopts a chain transmission mechanism, including an upper sprocket 11, a chain 12, a chain tensioning device 13, a lower sprocket 14, a connecting block 15, etc. The upper sprocket 11 is fixedly arranged on the transmission shaft 9, the lower sprocket 14 is fixed on the door storage section steel 16, the chain 12 is installed on the upper sprocket 11 and the lower sprocket 14, and both ends of the chain 12 are fixed on the connecting block 15. At the same time, the connecting block 15 is riveted and fixed to the door panel 1. The chain 12, the upper sprocket 11, the lower sprocket 14 and the connecting block 15 jointly form a closed-loop chain system. The upper sprocket 11 installed on the transmission shaft 9 rotates simultaneously with the transmission shaft 9. When the upper sprocket 11 drives the chain 12 to rotate, it simultaneously drives the connecting block 15 to move up and down. The door panel 1 and the connecting block 15 fixed on it move up and down together, that is, the opening and closing of the gate is completed by the chain 12 driving the door panel 1 to move up and down.

[0032] The door storage structure is composed of door storage section steel 16 and steel plates wrapped around the outside of the door storage section steel 16. The door storage section steel 16 is a framework structure, and the outer steel plate serves as the protective door storage shell 17. As mentioned above, the door storage structure is the space where the door panel 1 curls or folds when the gate is in the open state. The door storage section steel 16 can be directly designed in the shape of a chute, or other forms of chute structures can be set with reference to the door frame structure, so that when the door panel 1 curls or folds into the door storage structure, it can slide in the chute. A door storage roller track 18 is fixed inside the door storage structure and is connected to the door frame roller track 4 inside the door frame structure to form an integrated mechanism. The door frame roller track 4 is of a curled type. When the gate is opened, the door panel 1 enters the door storage along the track, curls along the door storage roller track 18, and the door panel 1 is stored inside the door storage structure, saving space and greatly reducing the volume of the entire gate.

[0033] Both the door frame roller track 4 and the door storage roller track 18 are made of section steel structures, and the size of the section steel structure is determined according to the size of the roller 5. The door frame roller track 4 is a straight track, and the door storage roller track 18 is a curled track. The straight track inside the door frame is seamlessly connected to the curled track inside the door storage. The function of the track is to limit the moving direction of the roller 5, so that the roller 5 moves along the direction of the track, thereby driving the door panel 1 to move along the direction of the track, achieving the linear movement or curling movement of the door panel 1.

[0034] The main body of the door panel 1 is made of a flexible material that can be curled or folded. In this embodiment, rubber is used. To increase the structural strength of the door panel 1, a door panel skeleton 19 is added to the rubber during the manufacturing of the rubber door panel 1. The door panel skeleton 19 is linear or in other shapes, such as zigzag or curved. It is distributed horizontally and parallelly at a certain interval in the rubber door panel 1 and is cured as a whole with the door panel 1. The parallel interval distribution between the door panel skeletons 19 can ensure a certain flexibility of the door panel 1 while ensuring the strength. The door panel skeleton 19 can be made of aluminum alloy section steel. The aluminum alloy section steel is light in weight and high in strength, and can reduce the weight of the door panel 1 while ensuring the strength. The interval distance between the door panel skeletons 19 and the size of the door panel skeleton 19 are related to the curvature of the door bank roller track 18. The smaller the curvature, the larger the interval distance between the door panel skeletons 19 and the smaller the section steel size. As another way to increase the strength of the door panel 1, an associated structure can be added to the door panel 1. For example, it can be connected by a thin steel wire rope or a thin chain between the parallel door panel skeletons 19 (not shown in the figure), or fibers can be added to the door panel, or fibers can be directly added to the material of the door panel 1. Because the door panel 1 has the function of curling or folding, but as a water-blocking door body, even if it is made of a flexible material, it should have the most basic water-blocking strength. Here, the water-blocking strength can be enhanced by the door panel skeleton 19 and the associated structure. Of course, if the strength of the flexible material itself plus the door panel skeleton 19 is sufficient to ensure the strength, then the associated structure is not necessary; and if, on the premise of meeting the curling and folding functions of the door panel 1, the strength can be ensured by the associated structure, then the door panel skeleton 19 is not necessary; it can also be ensured by the door panel skeleton 19 and the associated structure together. In this case, the associated structure can be arranged between two adjacent door panel skeletons 19.

[0035] Rollers 5 are provided on both sides of the door panel 1. The rollers 5 are fixed at both ends of the door panel skeleton 19 to ensure the structural stability of the door panel 1. The rollers 5 roll and move under the restriction of the door frame roller track 4 and the door bank roller track 18, making a linear up and down movement on the straight track inside the door frame and a curling movement in the curling track inside the door bank. Connecting blocks 15 are installed on both sides at the upper end of the door panel 1. The connecting blocks 15 are fixedly riveted to the door panel 1. When the chain 12 drives the connecting blocks 15 to move, the connecting blocks 15 can drag the door panel 1 to move upward to close the gate, or drag the door panel 1 to move downward to curl into the door bank structure to open the gate.

[0036] Since the main body of the structure of the door panel 1 is made of elastic rubber material, the door panel 1 can achieve a sealing effect by closely fitting with the frame structure at the inlet and outlet of the gate. When the gate is closed, the door panel 1 moves upward under the drive of the chain 12. The door panel 1 passes through the gap between the inlet doorframe section steel 21 and the outlet doorframe section steel 22, and this gap is slightly smaller than the thickness of the door panel 1, that is, an interference fit is formed between the thickness of the door panel 1 and the width of the chute. At this time, the door panel 1 will be pressed to closely fit with the doorframe section steel structure to form a sealing structure. There is no need to install a seal on the inner side of the doorframe like in the prior art, and a good seal can be achieved only through the structure and material of the door panel 1 itself.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
