Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically to a hinge with displacement compensation. Background Technology

[0002] In enclosed equipment such as hyperbaric oxygen chambers and medical isolation chambers, the sealing performance of the doors directly affects the safety and functionality of the equipment. Traditional door hinge structures typically use standard hinges or rotary hinges, with the doors opening and closing through the rotation of the hinge axis.

[0003] In the existing technology, the hatch hinge only has one rotation function. The hinge is connected to the same side of the hatch and the hatch. When the hatch is closed, the hatch end face near the hinge presses against the sealing strip on the hatch door opening first. The hatch end face away from the hinge needs to be forcibly pressed against the hatch and the hatch through a mechanical lock. In this state, there will be a small gap between the hatch end face and the sealing strip, which causes the interior of the hatch to take longer to reach the optimal pressure state. Utility Model Content

[0004] The purpose of this invention is to provide a hinge with displacement compensation, which aims to solve the problem in the prior art that there are small gaps after the hatch is closed with the cabin body through the hinge, resulting in a weakened sealing effect.

[0005] To achieve the above objectives, this utility model provides a hinge with displacement compensation, comprising: a fixed mounting plate, one side of which is vertically connected to a connecting seat, the connecting seat comprising a first connecting block and a second connecting block connected in sequence, the first connecting block being closer to the fixed mounting plate, and the second connecting block having a through-hole along its length; a first hinge member, one end of which is hinged to the first connecting block via a first pin; a second hinge member, one end of which is hinged to the other end of the first hinge member via a second pin, and the other end of which is hinged to the second connecting block via a third pin, the third pin being inserted into the through-hole; and a hinge plate, one end of which is rotatably connected to the third pin.

[0006] Furthermore, a return spring is provided perpendicularly between the fixed mounting plate and the second hinge member, and the first hinge member is provided with a clearance hole for the return spring to pass through.

[0007] Furthermore, the mounting plate is provided with screw connection holes.

[0008] Furthermore, the end of the first connecting block is provided with an adjusting screw that is inserted into the strip hole.

[0009] Furthermore, the fixed mounting plate, the first connecting block, and the second connecting block are an integral structure.

[0010] Furthermore, the height of the first connecting block is greater than the height of the second connecting block.

[0011] Furthermore, the hinge plate is provided with door panel connection holes.

[0012] The present invention provides a displacement-compensated hinge, which, compared with the prior art, has one end of the first hinge member and the second hinge member respectively hinged to the first connecting block and the second connecting block, and the other end of the first hinge member and the second hinge member hinged together, forming a V-shaped connection. The second hinge member can move linearly within the strip hole on the second connecting block through the third pin. The hinge plate is rotatably connected to the third pin and is connected to the hatch. When the hatch closes, the hatch end face close to the hinge contacts the sealing strip on the hatch body door opening and moves forward. After the hatch is locked, it moves backward, allowing the hatch end face to contact the sealing strip in all directions. The pressure distribution at the sealing interface is uniform, improving the sealing effect between the hatch and the hatch body after closing. Attached Figure Description

[0020] The present invention will be described in detail below with reference to specific embodiments.

[0021] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, a hinge with displacement compensation includes a fixed mounting plate 10, a connecting seat, a first hinge member 20, a second hinge member, and a hinge plate 40.

[0024] A connecting seat is vertically connected to one side of the fixed mounting plate 10. The fixed mounting plate 10 and the connecting seat are arranged in an L-shape. The connecting seat is a convex body and includes a first connecting block 11 and a second connecting block 12 connected in sequence. The first connecting block 11 is close to the side of the fixed mounting plate 10, and the second connecting block 12 has a strip hole 13 through it along its length direction.

[0025] The fixed mounting plate 10, the first connecting block 11, and the second connecting block 12 are integral structures formed by machining.

[0026] One end of the first hinge member 20 is hinged to the first connecting block 11 via the first pin 21. One end of the second hinge member 30 is hinged to the other end of the first hinge member 20 via the second pin 31. The other end of the second hinge member 30 is hinged to the second connecting block 12 via the third pin 41, which passes through the strip hole 13. The first hinge member 20 and the second hinge member 30 are connected in a V-shape and are located in front of the fixed mounting plate 10.

[0027] One end of the hinge plate 40 is rotatably connected to the third pin 41 for connecting the hatch.

[0028] In practice, the fixed mounting plate 10 is connected to the side of the hatch door opening by screws, and the hinge plate 40 is connected to the outer end face of the hatch. When the hatch is closed, one end of the third pin 41 and the second hinge 30 moves forward in the strip hole 13, so that the inner end face of the hatch is parallel to the sealant on the hatch door opening. Then the hatch is closed and locked. At this time, one end of the third pin 41 and the second hinge 30 moves backward in the strip hole 13, so that the end face of the hatch is in full contact with the sealing strip. The pressure distribution at the sealing interface is uniform, which improves the sealing effect between the hatch and the hatch after the hatch is closed and helps to shorten the time the hatch is under pressure during operation.

[0029] In this embodiment, a return spring 14 is vertically provided between the fixed mounting plate 10 and the second hinge member 30, and the first hinge member 20 is provided with a clearance hole for the return spring 14 to pass through. This serves to reset the second hinge member 30 and the hinge plate 40 after they have been pressed together.

[0030] In this embodiment, the mounting plate 10 is provided with screw connection holes 16 for mounting on the cabin body by screws.

[0031] In this embodiment, the end of the first connecting block 11 is provided with an adjusting screw 15 that inserts into the strip-shaped hole 13. The displacement distance of the third pin 41 can be adjusted according to the thickness of the sealing strip to accommodate sealing strips of different thicknesses.

[0032] In this embodiment, the height of the first connecting block 11 is greater than the height of the second connecting block 12, so that one end of the second hinge 30 and one end of the hinge plate 40 are both connected to the third pin 41.

[0033] In this embodiment, the hinge plate 40 is provided with a door panel connection hole 42 for mounting on the hatch with screws.

[0034] The present invention provides a displacement-compensated hinge, which, compared with the prior art, has one end of the first hinge member 20 and the second hinge member 30 respectively hinged to the first connecting block 11 and the second connecting block 12, and the other end of the first hinge member 20 and the second hinge member 30 hinged together in a V-shaped connection state. The second hinge member 30 can move linearly in the strip hole 13 on the second connecting block 12 through the third pin 41. The hinge plate 40 is rotatably connected to the third pin 41 and is connected to the hatch. When the hatch closes, the hatch end face close to the hinge contacts the sealing strip on the hatch door opening and moves forward. After the hatch is locked, it moves backward, so that the hatch end face contacts the sealing strip in all directions. The pressure distribution at the sealing interface is uniform, which improves the sealing effect between the hatch and the hatch body after the hatch is closed.

[0035] Where there is no conflict, the above embodiments and features can be combined with each other.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
