Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic gate doors, in particular to a pneumatic gate door with a buffer function. Background Art

[0002] A pneumatic gate is a gate that uses an air source to open and close. The pneumatic gate cylinder uses compressed air as a medium, converts its energy into mechanical energy, and realizes linear motion. Existing pneumatic gates still have certain defects when in use.

[0003] In the prior art, pneumatic gate doors are mainly used to cut off or adjust the flow in pipelines to prevent medium backflow and pipeline leakage. During the use of pneumatic gate doors, the door panels can be raised and lowered quickly. Since the door frame and door panels are both made of metal, the door panels are prone to a large collision force with the door frame during the rapid descent, thereby affecting the service life of the door panels. Utility Model Content

[0004] The utility model aims to provide a pneumatic gate door with a buffering function, so as to solve the problem that the pneumatic gate doors currently on the market are difficult to buffer as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pneumatic gate door with a buffering function, comprising: a door frame body, a cylinder body, a telescopic rod and a door panel, the top of the door frame body is installed with a cylinder body, the bottom end of the cylinder body is connected with a telescopic rod, and the end of the telescopic rod is installed with a door panel.

[0006] Preferably, a first rubber plate is bonded to the surface of the door frame body, a connecting block is welded to the outer side of the door plate close to the first rubber plate, a sliding groove is provided at the bottom of the connecting block, and a buffer spring is connected to the inside of the sliding groove.

[0007] Preferably, one end of the buffer spring is connected to a buffer block, both sides of the buffer block are connected to sliding blocks, and a second rubber plate is bonded to the bottom of the door panel.

[0008] Preferably, a sliding structure is formed between the buffer block and the connecting block through a sliding groove, and the shape of the buffer block is T-shaped.

[0009] Preferably, a fixing groove is provided at the bottom of the door frame body close to the telescopic rod, and a telescopic hose is sleeved on the outer side of the telescopic rod.

[0010] Preferably, the outer side of the telescopic hose is connected to a connecting plate, and the interior of the connecting plate is penetrated and connected to a plastic knob.

[0011] Preferably, the outer side of the telescopic hose away from the connecting plate is connected to a fixing block, and the top of the door panel is connected to a rubber clamping column.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: for the pneumatic gate door with a buffering function, when the door panel is about to be closed, the buffer block at the bottom of the connecting block can contact the first rubber plate. At this time, the buffer block will produce an opposite force when squeezing the first rubber plate. When the telescopic hose is unfolded, it can drive the fixed block to engage with the rubber clamping column, so that the telescopic hose can protect the telescopic rod. The telescopic hose can greatly reduce the adhesion of external dust and water droplets on the surface of the telescopic rod, prevent external dust and water droplets from entering the inside of the cylinder body, and make the cylinder body less likely to malfunction during use.

[0013] 1. The pneumatic gate door can lift the door panel by controlling the cylinder body. Since the door panel descends quickly, it is easy for the door panel to collide with the inside of the door frame body, affecting the service life of the door panel. When the door panel is about to close, the buffer block at the bottom of the connecting block can contact the first rubber plate. At this time, the buffer block will produce an opposite force on the first rubber plate, so that the buffer block can drive the slider to slide along the slide groove inside the connecting block. When the buffer block slides, it can compress the buffer spring. When the door panel is completely closed, the first rubber plate and the second rubber plate will be deformed, and the buffer spring will be compressed to the maximum extent. The first rubber plate, the second rubber plate and the buffer spring can make the door panel play an effective buffering effect during the rapid descent, avoiding the direct collision between the bottom of the door panel and the door frame body, thereby extending the service life of the door panel.

[0014] 2. During the use of the pneumatic gate door, dust and water droplets on the surface of the telescopic rod will enter the interior of the cylinder body, causing internal contamination of the cylinder body, thereby affecting the normal use of the cylinder body. When the connecting plate moves, the telescopic hose and the fixed block can be driven to move. When the connecting plate and the telescopic hose are both sleeved on the outside of the telescopic rod, the plastic knob can be rotated. When the plastic knob is rotated, it can be threadedly fixed to the door frame body through the fixing groove. When the telescopic hose is unfolded, it can drive the fixed block and the rubber clamping column to engage and dock, so that the telescopic hose can protect the telescopic rod. The telescopic hose can greatly reduce the adhesion of external dust and water droplets on the surface of the telescopic rod, prevent external dust and water droplets from entering the interior of the cylinder body, and make the cylinder body less prone to malfunction during use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 3 It can be seen that the utility model provides a technical solution: a pneumatic gate door with a buffering function, comprising: a door frame body 1, a cylinder body 2, a telescopic rod 3 and a door panel 4, the cylinder body 2 is installed on the top of the door frame body 1, the bottom end of the cylinder body 2 is connected to the telescopic rod 3, the end of the telescopic rod 3 is installed with the door panel 4, the surface of the door frame body 1 is bonded with a first rubber plate 5, a connecting block 6 is welded to the outer side of the door panel 4 close to the first rubber plate 5, a slide groove 7 is provided at the bottom of the connecting block 6, a buffer spring 8 is connected inside the slide groove 7, one end of the buffer spring 8 is connected to a buffer block 9, both sides of the buffer block 9 are connected to sliders 10, a second rubber plate 11 is bonded to the bottom of the door panel 4, a sliding structure is formed between the buffer block 9 and the connecting block 6 through the slide groove 7, and the shape of the buffer block 9 is T-shaped.

[0022] During specific implementation, the pneumatic gate door can make the door panel 4 rise and fall by controlling the cylinder body 2. Since the door panel 4 descends at a fast speed, it is easy for the door panel 4 to collide with the inside of the door frame body 1, which affects the service life of the door panel 4. When the telescopic rod 3 drives the door panel 4 to descend, the door panel 4 can drive the connecting block 6 and the second rubber plate 11 to descend. When the door panel 4 is about to close, the buffer block 9 at the bottom of the connecting block 6 can contact the first rubber plate 5. At this time, the buffer block 9 will produce an opposite force on the first rubber plate 5, so that the buffer block 9 can drive the slider 10 to slide along the slide groove 7 inside the connecting block 6. When the buffer block 9 slides, it can compress the buffer spring 8. At the same time, the second rubber plate 11 at the bottom of the door panel 4 can contact the inner wall of the door frame body 1. When the door panel 4 is fully closed, the first rubber plate 5 and the second rubber plate 11 will be deformed, and the buffer spring 8 will be compressed to the maximum extent.

[0023] See also Figure 1 , Figure 2 and Figure 3 It can be seen that the first rubber plate 5, the second rubber plate 11 and the buffer spring 8 can provide an effective buffering effect when the door panel 4 is rapidly lowered, thereby preventing the bottom of the door panel 4 from directly colliding with the door frame body 1, thereby extending the service life of the door panel 4.

[0024] See also Figure 1 , Figure 2 and Figure 4 It can be seen that a fixing groove 12 is provided at the bottom of the door frame body 1 near the telescopic rod 3, a telescopic hose 13 is sleeved on the outer side of the telescopic rod 3, a connecting plate 14 is connected to the outer side of the telescopic hose 13, a plastic knob 15 is penetrated and connected to the inside of the connecting plate 14, a fixing block 16 is connected to the outer side of the telescopic hose 13 away from the connecting plate 14, a rubber clamping column 17 is connected to the top of the door panel 4, and a clamping structure is formed between the rubber clamping column 17 and the fixing block 16.

[0025] During specific implementation, when the pneumatic gate door is in use, dust and water droplets on the surface of the telescopic rod 3 will enter the interior of the cylinder body 2, causing internal contamination of the cylinder body 2, thereby affecting the normal use of the cylinder body 2. Before installing the door panel 4, the connecting plate 14 can be pushed. When the connecting plate 14 moves, the telescopic hose 13 and the fixed block 16 can be driven to move. When the connecting plate 14 and the telescopic hose 13 are both sleeved on the outside of the telescopic rod 3, the plastic knob 15 can be rotated. When the plastic knob 15 is rotated, it can be threadedly fixed to the door frame body 1 through the fixing groove 12. At this time, the door panel 4 can be installed at the end of the telescopic rod 3, and the telescopic hose 13 can be unfolded. When the telescopic hose 13 is unfolded, the fixed block 16 can be driven to engage and dock with the rubber clamping column 17, so that the telescopic hose 13 can protect the telescopic rod 3.

[0026] See also Figure 1, Figure 2 and Figure 4 It can be seen that the telescopic hose 13 can greatly reduce the adhesion of external dust and water droplets on the surface of the telescopic rod 3, prevent external dust and water droplets from entering the cylinder body 2, and make the cylinder body 2 less likely to malfunction during use.

[0027] In summary, when the pneumatic gate door with buffer function is used, when compressed air enters the cylinder body 2, the telescopic rod 3 moves up, thereby opening the door panel 4. When the gas inside the cylinder body 2 is discharged, the telescopic rod 3 descends, thereby closing the door panel 4. The pneumatic gate door is a prior art and will not be described in detail here. When the door panel 4 is fully closed, the first rubber plate 5 and the second rubber plate 11 will be deformed, and the buffer spring 8 will be compressed to the maximum extent. The first rubber plate 5, the second rubber plate 11 and the buffer spring 8 can effectively play a role in the rapid descent of the door panel 4. The cushioning effect prevents the bottom of the door panel 4 from directly colliding with the door frame body 1, thereby extending the service life of the door panel 4. When the telescopic hose 13 is unfolded, it can drive the fixed block 16 to engage with the rubber clamping column 17, so that the telescopic hose 13 can protect the telescopic rod 3. The telescopic hose 13 can greatly reduce the adhesion of external dust and water droplets on the surface of the telescopic rod 3, prevent external dust and water droplets from entering the cylinder body 2, and make the cylinder body 2 less likely to malfunction during use.
