[0002] As the name suggests, anti-collision doors are doors that prevent collisions. They can be opened in both directions by collision and can be automatically closed by gravity after a person or object passes through. Non-electric doors are called anti-collision free doors. They are usually made of steel plates on both sides and wood in the middle. The lower part uses anti-collision polymer polyethylene plates to extend the service life of the door.

[0003] The existing anti-collision wooden door usually adopts a polyethylene plate fixed on the lower part of the wooden door, which has a small buffering effect and can only protect the door body, but cannot effectively prevent the wooden door from being deformed after being hit for a long time. Summary of the invention

[0004] The main purpose of the present invention is to solve the problem that the buffering effect is small and cannot effectively prevent the deformation of the wooden door after being hit for a long time, and to provide an anti-collision wooden door.

[0005] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0006] A collision-proof wooden door comprises a door frame and a door leaf arranged on the inner side of the door frame, wherein the door leaf is composed of two fixed plates and a wooden door body arranged between the two fixed plates, a buffer component is installed at the lower part of the door leaf, the buffer component comprises a mounting plate, a plurality of rubber tubes are installed on the mounting plate, a liquid storage cavity is provided inside the rubber tube, a buffer solution is provided in the liquid storage cavity, a buffer cavity is provided on the wooden door body, an extrusion plate is installed in the buffer cavity, and a spring is provided between the extrusion plate and the inner wall of the buffer cavity.

[0007] Preferably, a plurality of connecting bolts are arranged between the two fixing plates.

[0008] Preferably, a plurality of the rubber tubes are arranged from small to large in diameter and mounted on the mounting plate on a side close to the door frame.

[0009] Preferably, a liquid injection port is provided on the upper portion of the rubber tube, and a sealing valve is installed on the liquid injection port.

[0010] Preferably, fixing heads are provided at both upper and lower ends of the rubber tube, and the rubber tube is mounted on the mounting plate by bolts.

[0011] Preferably, the buffer is a calcium-based grease or a sodium-based grease.

[0012] Preferably, the buffer solution is injected into the liquid storage chamber when the rubber tube is squeezed by the squeezing plate.

[0013] Preferably, an avoidance groove is provided on the fixing plate.

[0014] Preferably, one end of the door leaf is rotatably connected to the door frame via a hinge.

[0015] Preferably, a protective rubber strip is provided at the other end of the door leaf.

[0016] Beneficial technical effects of the present invention: According to the anti-collision wooden door of the present invention, when in use, when an object collides with the door leaf and pushes the door open, it will first contact the buffer component installed at the bottom of the door leaf, and use the rubber tube and the buffer solution inside it for buffering. Secondly, when the object collides with the rubber tube, the rubber tube will be squeezed toward the door leaf at the same time. At this time, the extrusion plate cooperates with the spring to further buffer. At the same time, after the spring deformation is reset, it can also be absorbed by the buffer solution in the rubber tube, which can effectively improve the buffering effect. The cooperation of the buffer solution and the rubber tube can make the hard contact of the collision become flexible contact, thereby increasing the service life of the equipment, and then can cooperate with the fixed plate to effectively protect the wooden door and effectively prevent the wooden door from deformation.

[0028] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0029] like Figure 1-Figure 10 As shown, the anti-collision wooden door provided in this embodiment includes a door frame 1 and a door leaf 2 arranged on the inner side of the door frame 1, the door leaf 2 is composed of two fixing plates 4 and a wooden door body 7 arranged between the two fixing plates 4, a buffer component is installed at the lower part of the door leaf 2, the buffer component includes a mounting plate 3, a plurality of rubber tubes 5 are installed on the mounting plate 3, a liquid storage cavity is opened inside the rubber tube 5, a buffer 9 is arranged in the liquid storage cavity, a buffer cavity is opened on the wooden door body 7, an extrusion plate 8 is installed in the buffer cavity, a spring is arranged between the extrusion plate 8 and the inner wall of the buffer cavity, when in use, when an object collides with the door leaf 2 to push the door open , it will first contact the buffer component installed at the bottom of the door leaf 2, and use the rubber tube 5 and the buffer solution 9 inside it for buffering. Secondly, when the object collides with the rubber tube 5, the rubber tube 5 will be squeezed toward the door leaf 2 at the same time. At this time, the extrusion plate 8 cooperates with the spring for further buffering. At the same time, after the spring deformation is reset, it can also be absorbed by the buffer solution 9 in the rubber tube 5, which can effectively improve the buffering effect, and the cooperation of the buffer solution 9 and the rubber tube 5 can make the hard contact of the collision become flexible contact, thereby increasing the service life of the equipment, and then can cooperate with the fixing plate 4 to effectively protect the wooden door and effectively prevent the wooden door from deformation.

[0030] In this embodiment, if Figure 2 , Figure 4 , Figure 5 , Figure 8 and Fig.10As shown, a plurality of connecting bolts are arranged between the two fixing plates 4, and a plurality of rubber tubes 5 are arranged from small to large in diameter and installed on the mounting plate 3 on the side close to the door frame 1. The outermost rubber tube 5 can have limited contact and collision, which is convenient for opening the door. A liquid injection port 6 is arranged on the upper part of the rubber tube 5, and a sealing valve is installed on the liquid injection port 6 for adding a buffer solution 9.

A protective rubber strip is provided at the other end of the door leaf 2 to ensure the fit between the two door leaves 2.

[0031] In this embodiment, if Figure 8 and Fig. 9 As shown, the buffer solution 9 is a calcium-based grease, which can reduce the fluidity of the buffer solution 9 and has wear resistance, so that it can effectively absorb when it is hit, and at the same time play a buffering effect. The buffer solution 9 is injected into the liquid storage cavity when the rubber tube 5 is squeezed by the squeezing plate 8. When the rubber tube 5 is squeezed, the space inside the rubber tube 5 is reduced with the help of the mounting plate 3, and the added buffer solution 9 can only fill up the liquid storage cavity of the rubber tube 5 when it is overstocked, so that it can effectively ensure that when an object collides with the rubber tube 5, the buffer solution 9 can flow to the area squeezed by the squeezing plate 8, and effectively use the squeezing plate 8 to cooperate with the spring for buffering, thereby improving the buffering effect.

[0032] In this embodiment, if Fig. 9 As shown, the buffer 9 is a sodium-based grease, and the use environment of the sodium-based grease is wider than that of the calcium-based grease, and can be flexibly adjusted according to the use environment.

Secondly, when the object collides with the rubber tube 5, the rubber tube 5 will be squeezed toward the door leaf 2 at the same time. At this time, the extrusion plate 8 cooperates with the spring to further buffer. At the same time, after the spring deformation is reset, it can also be absorbed by the buffer solution 9 in the rubber tube 5, which can effectively improve the buffering effect, and the cooperation of the buffer solution 9 and the rubber tube 5 can make the hard contact of the collision become flexible contact, thereby improving the service life of the equipment, and then can cooperate with the fixed plate 4 to effectively protect the wooden door and effectively prevent the wooden door from deformation.
