Description

Technical Field

[0001] This utility model belongs to the field of operating door sealing technology, specifically relating to a sealing structure for operating doors. Background Technology

[0002] In environments with high safety requirements, such as electrical operation workshops, closed management of testing or processing areas is crucial, and specialized operating doors with closed structures are usually required.

[0003] Existing control doors generally use a simple design with a single sealing gasket and a regular door lock. While this can achieve a basic sealing effect, it still has some shortcomings in practical applications. Relying solely on a single sealing structure with a sealing gasket and a regular door lock not only has limited sealing performance, but also easily creates gaps when the door is closed. This can easily lead to safety risks due to seal failure under high-pressure conditions or complex operating environments. Utility Model Content

[0004] In view of this, the present invention provides a sealing structure for operating doors, which can be guided by the inclined trajectory of the guide groove. After the operating door is closed, it can fit tightly against the edge of the door opening, effectively solving the problem of insufficient anti-leakage capability of traditional single sealing gaskets under high pressure conditions, and significantly improving the sealing effect and structural reliability.

[0005] To solve the above-mentioned technical problems, this utility model provides a sealing structure for an operating door, including two mounting plates and a sealing mechanism between the two mounting plates. The sealing mechanism includes sliding grooves respectively set in the mounting plates, each groove containing a sliding component. Support rods are provided at both ends of the opposite inner sides of the two sliding components. An operating door is provided between the four support rods. A sealing gasket is provided on one side of the operating door. Guide slots are provided on the opposite inner sides of the two mounting plates. The guide slots slide and cooperate with the support rods located on the same mounting plate. That is, guided by the inclined trajectory of the guide slots, the operating door can tightly fit the edge of the door opening after closing, effectively solving the problem of insufficient anti-leakage capability of traditional single sealing gaskets under high pressure conditions, and significantly improving the sealing effect and structural reliability.

[0006] An inclined slot is provided at one end of the guide slot and on the side of the middle near the sealing gasket, which is used to guide the operating door.

[0007] The sliding assembly includes sliding plates that are slidably connected to the sliding grooves. Each sliding plate has a rectangular groove, and a movable plate is slidably connected to each rectangular groove. Both ends of the movable plate have through openings that are adapted to each support rod. Support rods are fixedly installed on both ends of the opposite inner sides of the two sliding plates, thus providing sliding guide support.

[0008] The sliding assembly also includes multiple springs respectively disposed between the movable plate and its rectangular groove, which provide elastic support force.

[0009] It also includes a drive assembly, which includes lead screws that are rotatably connected to the slide grooves. The lead screws are threadedly connected to the sliding plates located in the same slide groove, thus playing a role in synchronous driving.

[0010] Each mounting plate has a motor at one end, and the motor's output shaft is fixedly connected to one end of the lead screw, thus serving as a transmission connection.

[0011] The movable plate has an open structure on the side near the sealing gasket, which provides an installation position.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The operator fixes the two mounting plates to the upper and lower ends of the doorway. When the operating door needs to be closed, the driving sliding plate slides synchronously along the slide groove. During the closing process, the two sliding plates drive the rectangular groove, the moving plate, the through opening, the support rod, and the operating door to move along the guide groove. During this process, the support rod slides along the trajectory of the guide groove. When it moves into the slot set at an inclination in the guide groove, the moving plate, the support rod, and the operating door overcome the elastic force of the spring and move along the rectangular groove towards the doorway. When the operating door moves, it presses against the doorway through the sealing gasket, thereby causing the sealing gasket to deform under pressure, ensuring a tight fit between the operating door and the edge of the doorway. This eliminates the leakage risk of traditional single sealing gaskets under high pressure. Guided by the inclination trajectory of the guide groove, the operating door can fit tightly against the edge of the doorway after closing, effectively solving the problem of insufficient anti-leakage capability of traditional single sealing gaskets under high pressure conditions, and significantly improving the sealing effect and structural reliability.

[0014] 2. When the operating door needs to be opened or closed, the external controller controls the motor to start synchronously. Its output shaft rotates, which drives the lead screw to rotate synchronously. When the lead screw rotates, it drives the sliding plate connected to it to slide synchronously along the slide groove, thereby playing the role of synchronous driving movement.

[0015] 3. The sealing gasket is a rubber sealing gasket, which can seal the connection between the operating door and the door opening, ensuring a good seal between the two. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] This embodiment provides a sealing structure for operating doors, such as... Figure 1-6 As shown: It includes two mounting plates 100, and a closing mechanism is provided between the two mounting plates 100. The closing mechanism includes sliding grooves 200 respectively set in the mounting plates 100. Each sliding groove 200 is provided with a sliding component. Each of the two sliding components has a support rod 201 at both ends of its opposite inner side. An operating door 202 is provided between the four support rods 201. A sealing gasket 203 is provided on one side of the operating door 202. Each of the two mounting plates 100 has a guide groove 204 on its opposite inner side. The guide groove 204 is slidably engaged with the support rod 201 located on the same mounting plate 100. An inclined slot is opened at one end and the middle of the guide groove 204 near the sealing gasket 203.

[0025] The operator fixes the two mounting plates 100 to the upper and lower ends of the doorway. When the operating door 202 needs to be closed, the driving sliding assembly slides synchronously along the slide groove 200. During the closing process, the two sliding assemblies drive the support rod 201 and the operating door 202 to move along the guide groove 204. During this process, the support rod 201 slides along the trajectory of the guide groove 204. When it moves into the slot set at an inclination of the guide groove 204, the support rod 201 and the operating door 202 overcome the elasticity of the sliding assembly and move towards the doorway. When the operating door 202 moves, it fits tightly against the doorway through the sealing gasket 203, thereby causing the sealing gasket 203 to deform under pressure, ensuring that the operating door 202 fits tightly against the edge of the doorway, eliminating the leakage risk of traditional single sealing gaskets under high pressure. Guided by the inclination trajectory of the guide groove 204, the operating door 202 can actively fit against the doorway structure when closed, effectively solving the problem of insufficient anti-leakage capability of traditional single sealing gaskets under high pressure conditions, and significantly improving the sealing effect and structural reliability.

[0026] like Figure 1-6 As shown, the sliding assembly includes sliding plates 300 that are slidably connected to the sliding grooves 200. Each sliding plate 300 has a rectangular groove 301. Each rectangular groove 301 is slidably connected to a movable plate 302. Both ends of the movable plate 302 are provided with through openings 303 that are adapted to each support rod 201. Support rods 201 are fixedly installed on both ends of the opposite inner sides of the two sliding plates 300. The sliding assembly also includes a plurality of springs 304 that are respectively disposed between the movable plate 302 and its rectangular groove 301.

[0027] The support rod 201 slides along the trajectory of the guide slot 204. When it moves into the slot where the guide slot 204 is inclined, the moving plate 302, the support rod 201 and the operating door 202 overcome the elastic force of the spring 304 and move along the rectangular slot 301 toward the door opening. When the operating door 202 is opened, the spring 304 can provide a rebound force for the moving plate 302, the support rod 201 and the operating door 202.

[0028] like Figure 1-6 As shown, it also includes a drive assembly, which includes lead screws 400 rotatably connected to the slide grooves 200 respectively. The lead screws 400 are threadedly connected to the sliding plates 300 located in the same slide grooves 200. One end of each mounting plate 100 is provided with a motor 401. The output shaft of the motor 401 is fixedly connected to one end of the lead screw 400 respectively. The side of the moving plate 302 near the sealing gasket 203 has an open structure.

[0029] An external controller regulates the synchronous start of motor 401. The rotation of its output shaft drives the lead screw 400 to rotate synchronously. When the lead screw 400 rotates, it drives the sliding plate 300, which is threaded to it, to slide synchronously along the slide groove 200. Motor 401 is controlled by an external controller, which is an MC600 series synchronous controller. Motor 401 is an AZX series.

[0030] The working principle of the sealing structure for the operating door provided by this utility model is as follows: First, the operator fixes two mounting plates 100 to the upper and lower ends of the door opening. When the operating door 202 needs to be closed, the external controller controls the motor 401 to start synchronously. Its output shaft rotates, driving the lead screw 400 to rotate synchronously. When the lead screw 400 rotates, it drives the sliding plate 300, which is threaded to it, to slide synchronously along the slide groove 200. During the closing process, the two sliding plates 300 drive the rectangular groove 301, the moving plate 302, the through opening 303, the support rod 201, and the operating door 202 to move along the guide groove 204. During this process, the support rod 201 slides along the trajectory of the guide groove 204. When the operating door 202 moves into the inclined slot of the guide groove 204, the moving plate 302, the support rod 201, and the operating door 202 overcome the elastic force of the spring 304 and move along the rectangular groove 301 towards the door opening. When the operating door 202 moves, it presses against the door opening through the sealing gasket 203, thereby causing the sealing gasket 203 to deform under pressure, ensuring that the operating door 202 fits tightly against the edge of the door opening, eliminating the leakage risk of traditional single sealing gaskets under high pressure. Guided by the inclined trajectory of the guide groove 204, the operating door 202 can actively fit against the door opening structure when closing, effectively solving the problem of insufficient anti-leakage capability of traditional single sealing gaskets under high pressure conditions, and significantly improving the sealing effect and structural reliability.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and 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.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
