Description

Technical Field

[0001] This utility model relates to the field of automatic door technology, and in particular to a two-wing door post with an anti-pinch sensor mounting groove. Background Technology

[0002] Two-wing automatic revolving doors are widely used in the entrances and exits of high-end buildings such as hotels, shopping malls, and office buildings due to their aesthetic appeal and high throughput. To ensure safety and prevent pedestrians from being pinched during the door's rotation, installing anti-pinch sensors on the pillars of these automatic doors has become a standard safety feature. The anti-pinch sensors can detect the area between the door wings and the pillars in real time; once an obstacle is detected, they immediately control the door's opening and stopping, effectively preventing accidents.

[0003] In existing technical solutions, anti-pinch sensors are typically fixed directly to the surface of the two-wing door pillars or into pre-reserved simple grooves using screws, clips, or adhesives. While this installation method achieves basic fixing functionality, it has revealed significant shortcomings in actual use and maintenance.

[0004] Because anti-pinch sensors are precision electronic components, they may malfunction due to aging, environmental factors, or accidental impacts during long-term operation, requiring regular inspection or replacement. Under the aforementioned traditional fixing methods, replacing the sensor is often a cumbersome process, requiring maintenance personnel to use specialized tools to carefully disassemble the fixing components and decorative covers, operating in confined spaces, which is time-consuming and labor-intensive.

[0005] This inconvenient disassembly and assembly process not only significantly increases subsequent maintenance costs and the downtime of automatic doors, but repeated disassembly and assembly operations can also easily damage the finish or structure of the door pillars. The root cause lies in the fact that existing pillar structures lack an integrated mounting groove structure that combines convenience and stability, specifically designed for the installation and maintenance of sensors.

[0006] Therefore, a two-wing door support column with an anti-pinch sensor mounting slot is proposed to solve the above problems. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a two-wing door post with an anti-pinch sensor mounting groove, aiming to improve the problems of complex installation and replacement process of anti-pinch sensors and lack of protective structure in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a two-wing door pillar with an anti-pinch sensor mounting groove, comprising: a pillar body and a mounting assembly; the pillar body has a second groove inside, and a first groove is formed on the inner wall of the second groove; the mounting assembly is slidably fitted in the second groove, and the mounting assembly includes a fixing box, a support plate, a shaped plate, a first limiting block, a limiting plate, a second limiting block, and a spring.

[0009] The mounting component and the first groove of the column body form a mating structure that allows for quick locking and unlocking.

[0010] Furthermore, the support plates are symmetrically arranged on both sides of the fixed box; the top of the irregular plate is fixedly connected to the bottom of the fixed box; the two sides of the irregular plate are rotatably connected to first limiting blocks, which are rotatably engaged with the first groove; a limiting plate is fixedly connected to the bottom of the support plate, the limiting plate abuts against the outer wall of the first limiting block, and the limiting plate abuts against the upper surface of the first limiting block; a second limiting block is provided inside the irregular plate, and a spring is provided between the second limiting block and the inner wall of the irregular plate.

[0011] Preferably, the support plate, the first limiting block, and the limiting plate are all symmetrically arranged along the central axis of the fixing box.

[0012] Preferably, the support plate and the fixing box are an integral structure.

[0013] Preferably, when the second limiting block is pressed, the second limiting block moves and directly abuts against the first limiting block, so as to push the first limiting block to disengage from the first groove.

[0014] Preferably, the two-wing door pillar with anti-pinch sensor mounting groove further includes a fixing component, which includes a cover plate, a clamping plate, and a limiting post.

[0015] Preferably, the cover plate is detachably closed at the opening of the second groove located on the outside of the column body.

[0016] Preferably, the clamps are symmetrically arranged and fixed to the inner side of the cover plate, and elastically abut against the inner wall of the second groove.

[0017] Preferably, the clamping plate is made of an elastic material and has an outwardly convex arc-shaped structure to form a pressing fit with the inner wall of the second groove.

[0018] Preferably, the limiting post extends from the inside of the cover plate and abuts against the clamping plate to limit the movement.

[0019] This utility model has the following beneficial effects: In this utility model, by setting a pluggable installation component and designing a mechanical self-locking and press-to-unlock structure consisting of a first limiting block, a first groove, a shaped plate and a second limiting block between the installation component and the inner wall of the column body, the problem of complex installation process and time-consuming and labor-intensive replacement and maintenance of anti-pinch sensors in the prior art is solved. It achieves the technical effect of quick installation and disassembly and replacement of sensors without complicated tools, which greatly improves maintenance convenience and work efficiency.

[0020] 2. In this utility model, by setting a fixing assembly consisting of a cover plate, a clamping plate and a limiting post, and using the elastic contact between the clamping plate and the inner wall of the groove of the column body for fixing, the problem of the sensor being easily exposed and damaged due to lack of effective protection after installation is solved. The technical effect of completely embedding the sensor inside the column body for reliable protection is achieved, which extends the service life of the sensor and enhances the overall reliability of the device.

[0023] 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.

[0024] like Figures 1 to 4 As shown, the two-wing door pillar with anti-pinch sensor mounting groove includes a pillar body 1 and a mounting component 2. The pillar body 1 serves as the mounting base frame of the entire device, and the mounting component 2 is a functional module that slides inside the pillar body 1. Specifically, a second groove 5 is provided inside the pillar body 1, and a first groove 208 is also provided on the inner wall of the second groove 5. The mounting component 2 is installed or removed along the guide of the second groove 5, while the first groove 208 is used to cooperate with the locking structure of the mounting component 2.

[0025] Mounting assembly 2 is the core structure that supports the sensor body 3 and enables quick assembly and disassembly. Mounting assembly 2 includes a fixing box 202, a support plate 201, a shaped plate 206, a first limiting block 203, a limiting plate 204, a second limiting block 205, and a spring 207. The fixing box 202 accommodates the sensor body 3. Support plates 201 are symmetrically arranged on both sides of the fixing box 202. The support plates 201 and the fixing box 202 are an integral structure, providing stable support for the fixing box 202 during installation in the second groove 5. The bottom of the fixing box 202 is fixedly connected to the shaped plate 206, and the two sides of the shaped plate 206 are rotatably connected to the first limiting blocks 203. When the mounting assembly 2 is pushed into the predetermined position of the second groove 5, the spring 207 is activated. The first limiting block 203 can rotate and engage with the first groove 208 on the column body 1, thereby locking the entire mounting assembly 2 inside the column body 1. To ensure the stability and reliability of the locking structure, a limiting plate 204 is fixedly connected to the bottom of the support plate 201. The limiting plate 204 abuts against the upper surface of the first limiting block 203 and restricts the rotation range of the first limiting block 203 through structural cooperation, preventing the first limiting block 203 from accidentally coming out of the first groove 208. The interior of the irregular plate 206 is hollow and a second limiting block 205 is provided. A spring 207 is provided between the second limiting block 205 and the inner wall of the irregular plate 206. The spring 207 provides an outward restoring force to the second limiting block 205.

[0026] During installation, the mounting assembly 2, which integrates the sensor body 3, is pushed into the column body 1 along the second groove 5. During the pushing process, the inclined surface of the irregular plate 206 will interfere with the inner wall of the column body 1, thereby forcing the first limiting blocks 203 on both sides to rotate and retract inward. When the mounting assembly 2 reaches the predetermined installation position, the first limiting block 203 is exactly aligned with the first groove 208. Under its own weight or the action of the preset elastic force, the first limiting block 203 rotates outward and is locked into the first groove 208. At this time, the limiting plate 204 is located above the first limiting block 203, which restricts the upward movement of the first limiting block 203, thereby completing the firm locking of the mounting assembly 2.

[0027] During disassembly and replacement, the second limiting block 205 is pressed externally, causing it to move inward and compress the spring 207. Simultaneously, the inner end of the second limiting block 205 drives the irregular plate 206. The irregular plate 206, through its internal linkage structure, pushes the first limiting blocks 203 on both sides, causing the first limiting blocks 203 to overcome their limiting effect and rotate inward, ultimately completely disengaging from the first groove 208. Once disengaged, the entire mounting assembly 2 can be easily pulled out of the second groove 5. After disassembly, the external force is removed, and the rebound force of the spring 207 pushes the second limiting block 205 back to its original position. In the entire solution, the support plate 201, the first limiting block 203, and the limiting plate 204 are all symmetrically arranged along the central axis of the fixing box 202, ensuring uniform force distribution and stable and reliable operation during locking and unlocking.

[0028] This embodiment also includes a fixing component 4 for protecting the mounting component 2. The fixing component 4 includes a cover plate 401, a clamping plate 402, and limiting posts 403. The cover plate 401 is detachably closed at the opening of the second groove 5 located on the outside of the column body 1 to protect the internal sensor body 3 from the influence of the external environment. The inner side of the cover plate 401 is fixedly connected to symmetrically arranged clamping plates 402. The clamping plates 402 are made of elastic material and have an outwardly convex arc structure. When the cover plate 401 is installed, the clamping plates 402 and the inner wall of the second groove 5 form an elastic abutment and compression fit, thereby firmly fixing the cover plate 401 to the column body 1. To further enhance the reliability of the fixing, multiple limiting posts 403 extend from the inner side of the cover plate 401. The limiting posts 403 abut against the clamping plates 402 to limit the position and prevent the clamping plates 402 from shifting position or failing elasticity during long-term use.

[0029] In a preferred embodiment, the support plate 201, the first limiting block 203, and the limiting plate 204 are all symmetrically arranged along the central axis of the fixing box 202. This symmetrical layout helps to balance the transmission of torque during locking and unlocking.

[0030] As another preferred embodiment, the support plate 201 and the fixing box 202 are manufactured as a single, robust component.

[0031] As a preferred design for the unlocking structure, the inner end of the second limiting block 205 forms a contact with the interior of the irregular plate 206 that can transmit thrust. The internal structure of the irregular plate 206 is also linked with the driving end of the first limiting block 203. This structural layout ensures that when the second limiting block 205 is pressed, the irregular plate 206 and the first limiting block 203 can be driven to disengage from the first groove 208 in sequence.

[0032] As a preferred solution for protecting the sensor body 3, this embodiment also includes a fixing component 4, which includes a cover plate 401 and a clamping plate 402 symmetrically fixed to the inner side of the cover plate 401. The cover plate 401 detachably closes the external opening of the second groove 5, and the clamping plate 402 forms an elastic abutment with the inner wall of the second groove 5.

[0033] Furthermore, the clamping plate 402 is preferably made of an elastic material, such as elastic steel or a polymer elastomer, and the structure of the clamping plate 402 is an outwardly convex arc-shaped structure, which generates elastic deformation during installation, thereby forming a stable pressing fit with the inner wall of the second groove 5.

[0034] Furthermore, the inner side of the cover plate 401 is integrally formed with multiple limiting posts 403. The limiting posts 403 extend from the inner surface of the cover plate 401 and abut against the inner surface of the clamping plate 402 to limit the movement and prevent the clamping plate 402 from loosening due to vibration or material fatigue.

[0035] Working principle: During installation, the mounting component 2, with the sensor body 3 already placed inside, is aligned with the second groove 5 on the column body 1 and pushed inward. During the pushing process, the guide slope of the irregular plate 206 at the bottom of the mounting component 2 contacts the inner wall of the second groove 5, forcing the first limiting blocks 203 rotatably connected to both sides of the irregular plate 206 to rotate and retract inward. When the mounting component 2 moves to the predetermined installation position, the first limiting block 203 is exactly aligned with the position of the first groove 208. Under the action of the preset elastic force, the first limiting block 203 automatically rotates outward and is locked into the first groove 208. At this time, the limiting plate 204 fixedly connected to the bottom of the support plate 201 is exactly abutting against the upper surface of the first limiting block 203, restricting the movement of the first limiting block 203, thereby completing the quick installation and automatic locking of the mounting component 2. When it is necessary to disassemble or replace the sensor body 3, press the exposed second limiting block 205 inward. The second limiting block 205 moves inward and compresses the spring 207. At the same time, the movement of the second limiting block 205 is converted into a pushing force on the first limiting blocks 203 on both sides through the internal linkage structure of the irregular plate 206. This drives the first limiting blocks 203 to overcome the limiting effect of the limiting plate 204 and rotate inward until the first limiting blocks 203 are completely disengaged from the first groove 208. At this moment, the lock on the mounting component 2 is released, and the operator can directly and smoothly pull the entire mounting component 2 out of the second groove 5, realizing convenient replacement and maintenance. When the pressing force is released, the rebound force of the spring 207 will push the second limiting block 205 back to the initial position, preparing for the next installation. After the mounting component 2 is locked, the cover plate 401 of the fixing component 4 is aligned with the opening of the second groove 5 and pushed in. During the installation of the cover plate 401, the clamping plate 402, which is fixed to the inner side of the cover plate 401 and has an outwardly convex arc structure, undergoes elastic deformation due to contact with the inner wall of the second groove 5. The continuous elastic resistance force generated by the clamping plate 402 firmly fixes the cover plate 401 to the column body 1. At the same time, the limiting post 403 on the cover plate 401 restricts the position of the clamping plate 402, enhancing the long-term stability of the fixation and ultimately providing effective physical protection for the internal sensor body 3.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
