A two-way cleanroom door

Abstract

This utility model discloses a two-way cleanroom door, including a door frame for support. Two sets of limiting slots are symmetrically formed on the inner end face of the door frame, and a fixing guide groove is formed between the two sets of limiting slots. By setting up limiting and supporting devices, this utility model allows the guide slide to elastically avoid movement of the hexagonal locking shaft via a limiting torsion spring during quick disassembly and maintenance of the cleanroom door shell. This enables the hexagonal locking shaft to quickly and easily pass through the hexagonal slots and be positioned inside the two sets of aligning locking seats, thus facilitating quick and convenient disassembly and maintenance of the cleanroom door shell. This effectively improves the ease of disassembly and maintenance of the cleanroom door shell. Simultaneously, the front and rear buffer baffles effectively improve the protection of the bottom of the cleanroom door shell, thereby increasing the overall service life of the cleanroom door.

Technical Field

[0001] This utility model relates to the field of cleanroom equipment technology, specifically a two-way cleanroom door. Background Technology

[0002] Two-way cleanroom doors are a type of door designed for frequent entry and exit and the maintenance of a high level of cleanliness. They are commonly found in operating rooms, pharmaceutical factories, laboratories, and other places. The door has a two-panel opening structure that can open to both sides simultaneously, providing more passage space and adapting to the needs of high-volume personnel or equipment entry and exit.

[0003] However, most existing two-way cleanroom doors are installed using hinges, which makes installation and disassembly relatively complex and inconvenient for quick disassembly and maintenance, thus reducing the practicality of the cleanroom door. Therefore, there is an urgent need for a two-way cleanroom door to solve the above-mentioned problems. Utility Model Content

When the cleanroom door housing is installed and disassembled, the hexagonal bracket shaft can be guided by the limiting torsion spring and the guide slide shaft to avoid misalignment, thereby providing sufficient guiding space for the positioning and alignment of the hexagonal bracket shaft and the hexagonal bracket groove, which facilitates the quick and convenient disassembly and assembly of the cleanroom door housing.

[0012] Preferably, the buffer baffle is made of rubber, which can effectively improve the protection against collisions between various load-bearing vehicles and the bottom of the cleanroom door housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a limiting device and a supporting device, allows the guide slide to elastically avoid the hexagonal locking shaft through the limiting torsion spring during the rapid disassembly and maintenance of the cleanroom door shell. This enables the hexagonal locking shaft to quickly and conveniently pass through the hexagonal locking groove and be limited to the interior of the two sets of aligning locking seats, thereby enabling the cleanroom door shell to be quickly and conveniently disassembled and maintained. This effectively improves the ease of disassembly and assembly of the cleanroom door shell. At the same time, the front and rear sets of buffer baffles effectively improve the protection of the bottom of the cleanroom door shell, thereby increasing the overall service life of the cleanroom door.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 The present invention provides an embodiment of a two-way purification door, including a purification door frame 4 for support, two sets of limiting slots 1 symmetrically opened on the inner end face of the purification door frame 4, and a fixing guide groove 5 opened between the two sets of limiting slots 1.

[0022] Limiting device 2 is fixedly installed on the inner end face of the purification door frame 4 through limiting slot 1. Limiting device 2 is used for alignment and elastic reset.

[0023] Support device 3, there are two sets of support device 3, and the two sets of support device 3 are rotatably locked onto the inner end face of the purification door frame 4 through the limiting device 2.

[0024] The limiting device 2 includes a support bracket 24, a limiting torsion spring 21 is fixedly provided on the upper end surface of the support bracket 24, a guide slide 23 is fixedly provided on the upper end surface of the limiting torsion spring 21, a hexagonal locking shaft 22 is fixedly provided at the center of the upper end surface of the guide slide 23, and a guide slide shaft 25 is fixedly provided at the center of the lower end surface of the guide slide 23.

[0025] The lower end face of the guide slide 25 is slidably engaged with the inner end face of the purification door frame 4 through the fixed guide groove 5. The fixed guide groove 5 can provide sufficient guiding foundation for the guide slide 25, thereby improving the stability of the hexagonal clamp 22.

[0026] The support device 3 includes a purification door housing 32. A positioning seat 34 is symmetrically arranged on the side end face of the purification door housing 32. A hexagonal slot 33 is opened at the center of the inner end face of the positioning seat 34. A window 31 is fixedly attached to the upper part of the inner end face of the purification door housing 32. Buffer baffles 35 are provided at the front and rear of the purification door housing 32.

[0027] The alignment bracket 34 is elastically fixed to the upper part of the support bracket 24 by matching the hexagonal slot 33 with the hexagonal bracket 22. When installing and disassembling the purification door housing 32, the hexagonal bracket 22 can be guided by the limiting torsion spring 21 and the guide slide 25, thereby providing sufficient guiding space for the positioning and alignment of the hexagonal bracket 22 and the hexagonal slot 33, which facilitates the quick and convenient disassembly and assembly of the purification door housing 32.

[0028] The buffer baffle 35 is made of rubber, which can effectively improve the protection against collisions between various load-bearing vehicles and the bottom of the purification door housing 32.

[0029] Working principle: When it is necessary to install the cleanroom door housing 32, the operator can use external tools to align and press down the two sets of guide slides 23, so that the hexagonal locking shaft 22 can move down through the elastic contraction of the limiting torsion spring 21. Then, the user can position the cleanroom door housing 32 into the limiting slot 1 through the alignment seat 34, so that the hexagonal locking shaft 22 and the hexagonal slot 33 are aligned. Then, the limiting of the guide slide 23 is released. At this time, the limiting torsion spring 21 can drive the hexagonal locking shaft 22 to rise and insert into the hexagonal slot 33, completing the limiting of the alignment seat 34. When frequently opening and closing, the limiting torsion spring 21 and the guide slide 25 can perform elastic torsional limiting, improving the reset stability of the cleanroom door housing 32. At the same time, the buffer baffle 35 can conveniently protect the bottom of the cleanroom door housing 32. Due to frequent opening and closing, and the possibility of moving tools hitting the bottom of the cleanroom door housing 32, the buffer baffle 35 can improve the external protection of the cleanroom door housing 32.
