Description

Technical Field

[0001] This utility model relates to the field of swing door technology, specifically a swing door that can swing up and down elastically. Background Technology

[0002] A swing door is a type of door that is fixed to one side of the door frame by hinges and can swing in one or two directions. It is commonly found in residential, commercial and public spaces. Its opening method is divided into inward opening or outward opening. Some designs are equipped with spring hinges to achieve automatic closing. It is made of various materials, including wood, metal and glass. Its advantages are simple structure and good sealing performance, but it requires reserved swing space and may affect the layout of narrow areas. It is suitable for indoor and outdoor doors, fire escape routes and other scenarios.

[0003] In high-traffic areas such as shops, swing doors that can open and close in both directions are needed to increase the speed of people passing through. Existing swing doors do not have the function of vertical elastic buffering. Currently, most swing doors use a spring-loaded hinge structure to connect with the door frame. Traditional spring-loaded hinges can only buffer and absorb forces in the front and back directions. When subjected to vertical forces, the impact force will be directly transmitted to the connection point with the door frame, which can easily cause the swing door to loosen and fall off. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a swing door that can swing up and down elastically, possessing the advantage of having an up-and-down elastic buffering function. This solves the problem that existing swing doors do not have an up-and-down elastic buffering function. Currently, most swing doors use a spring-loaded hinge structure to connect to the door frame. Traditional spring-loaded hinges can only buffer and absorb forces in the front-and-back direction. When subjected to forces in the up-and-down direction, the impact force will be directly transmitted to the connection point with the door frame, which can easily lead to the swing door loosening and falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a swing door that can flexibly swing up and down, comprising a door frame, two rectangular boxes fixedly connected to the left and right sides of the inner surface of the door frame, a movable block slidably connected between the inner walls of the two rectangular boxes on the same side of the door frame, dampers fixedly connected to the top and bottom of the movable block, the outer side of the damper fixedly connected to the inner wall of the rectangular box, a spring sleeved on the surface of the damper, one end of the spring connected to the inner wall of the rectangular box and the other end connected to the surface of the movable block, an L-shaped block connected to the side wall of the movable block, the L-shaped block penetrating the rectangular box, a sloping column fixedly connected to the top of the L-shaped block, a connecting block provided at the top of the sloping column, a sloping groove slidably connected to the sloping column at the bottom of the connecting block, and a door panel fixedly connected to the inner side of the connecting block.

[0006] As a preferred embodiment of this utility model, handles are fixedly connected to both the front and rear sides of the door panel, and the handles are U-shaped.

[0007] As a preferred embodiment of this invention, an observation window is provided at the upper front position of the door panel.

[0008] As a preferred embodiment of this utility model, sliders are fixedly connected to the front and rear sides of the inner wall of the rectangular box, and grooves that slide and connect with the sliders are provided on the front and rear sides of the movable block.

[0009] As a preferred embodiment of this utility model, the connecting block has a slot inside, and a T-shaped limiting block is slidably connected to the inner wall of the slot. The bottom of the T-shaped limiting block extends through the interior of the inclined groove and is fixedly connected to the top of the inclined column.

[0010] As a preferred embodiment of this invention, the rectangular box is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model first pushes the door panel, using the inclined surface and groove on the inclined column to move the connecting block and the door panel upward, opening the door panel. When pushing stops, due to gravity, the door panel and the connecting block move downward, causing the connecting block to rotate in the opposite direction along the inclined surface on the inclined column and reset. At this time, the door panel closes. At the same time as closing, the connecting block drives the spring and damper to absorb the impact force generated when resetting and closing, thereby achieving the effect of upper and lower elastic buffering function.

[0012] 2. By providing a handle, this utility model increases the contact area between the user's hands and the door panel, making it easier for the user to move the door panel. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, the present invention provides a swing door that can flexibly swing up and down, including a door frame 1. Two rectangular boxes 2 are fixedly connected to the left and right sides of the inner surface of the door frame 1. A movable block 3 is slidably connected between the inner walls of the two rectangular boxes 2 on the same side of the door frame 1. A damper 4 is fixedly connected to the top and bottom of the movable block 3. The outer side of the damper 4 is fixedly connected to the inner wall of the rectangular box 2. A spring 5 is sleeved on the surface of the damper 4. One end of the spring 5 is connected to the inner wall of the rectangular box 2, and the other end is connected to the surface of the movable block 3. An L-shaped block 6 is connected to the side wall of the movable block 3. The L-shaped block 6 penetrates the rectangular box 2. An inclined column 7 is fixedly connected to the top of the L-shaped block 6. A connecting block 8 is provided at the top of the inclined column 7. An inclined groove 9 that is slidably connected to the inclined column 7 is opened at the bottom of the connecting block 8. A door panel 10 is fixedly connected to the inner side of the connecting block 8.

[0017] refer to Figure 1 Handles 11 are fixedly connected to both the front and rear sides of the door panel 10. The handles 11 are U-shaped.

[0018] As a technical optimization of this utility model, by setting the handle 11, the contact area between the user's hands and the door panel 10 can be increased, making it more convenient for the user to move the door panel 10.

[0019] refer to Figure 1 An observation window 12 is provided on the upper front side of the door panel 10.

[0020] As a technical optimization of this utility model, by setting an observation window 12, the opposite side of the door panel 10 can be observed through the observation window 12, which is convenient for users.

[0021] refer to Figure 3 The front and rear sides of the inner wall of the rectangular box 2 are fixedly connected to sliders 14, and the front and rear sides of the movable block 3 are provided with sliding grooves 13 that are slidably connected to sliders 14.

[0022] As a technical optimization of this utility model, by setting the slider 14 and the groove 13, the range of motion of the movable block 3 can be limited to prevent the movable block 3 from shaking during use.

[0023] refer to Figure 4The connecting block 8 has a slot 16 inside, and a T-shaped limiting block 15 is slidably connected to the inner wall of the slot 16. The bottom of the T-shaped limiting block 15 extends through the interior of the inclined groove 9 and is fixedly connected to the top of the inclined column 7.

[0024] As a technical optimization of this utility model, by setting the slot 16 and the T-shaped limiting block 15, the range of motion of the inclined column 7 can be limited, preventing the inclined column 7 from detaching from the inclined slot 9 during use.

[0025] refer to Figure 3 The rectangular box 2 is made of stainless steel.

[0026] As a technical optimization of this utility model, by setting a rectangular box 2 made of stainless steel, it is possible to prevent the rectangular box 2 from rusting and to prevent the rectangular box 2 from being damaged due to rusting.

[0027] The working principle and usage process of this utility model are as follows: First, push the door panel 10. The door panel 10 drives the connecting block 8 to rotate around the inclined column 7. Simultaneously, the inclined surface and groove 9 on the inclined column 7 cause the connecting block 8 and the door panel 10 to move upwards, thus opening the door panel 10. When you stop pushing the door panel 10, due to gravity, the door panel 10 and the connecting block 8 move downwards. At the same time, gravity causes the connecting block 8 to rotate in the opposite direction along the inclined surface of the inclined column 7 and reset. At this point, the door panel 10 resets and closes. Simultaneously, the connecting block 8 applies a downward impact force to the inclined column 7. This impact force causes the inclined column 7 and the L-shaped block 6 to move downwards. The L-shaped block 6 causes the movable block 3 to move downwards. The movable block 3 presses down on the spring 5 and the damper 4, causing them to contract. The spring 5 and the damper 4 absorb the impact force generated during the reset and closure, thus achieving an elastic buffering effect.

[0028] In summary, this swing door, which can flexibly move up and down, solves the problem of existing swing doors lacking vertical elastic buffering by incorporating a door frame 1, rectangular box 2, movable block 3, damper 4, spring 5, L-shaped block 6, inclined column 7, connecting block 8, inclined groove 9, and door panel 10. Currently, most swing doors use spring-loaded hinges to connect to the door frame. Traditional spring-loaded hinges can only buffer and absorb forces in the forward and backward directions. When subjected to forces in the vertical direction, the impact force is directly transmitted to the connection point with the door frame, which can easily lead to the swing door loosening and falling off.
