Abstract
Description
Technical Field
[0001] This utility model relates to a novel pressureless locking sliding door for a hyperbaric oxygen chamber, belonging to the technical field of hyperbaric oxygen chamber door structure. Background Technology
[0002] The existing oxygen chamber sliding door structure includes a door body, a slider, a C-block, and a joint bearing. The door body is connected to the C-block via the joint bearing. One end of the slider is installed in the C-block, and the other end is slidably connected to the guide rail.
[0003] During the pressurization process inside the cabin, the current sliding door is subjected to strong pressure and compression in the front and back directions. Due to the limited forward and backward movement of the slider, the joint bearing and slider are subjected to significant stress during this process. Since the joint bearing is a slender structure, it is highly susceptible to breakage, and the slider is easily damaged. Furthermore, during rapid door opening and closing, the stress generated after the C-block is stopped is also concentrated on the joint bearing and slider, which can similarly cause deformation and breakage of the joint bearing, as well as damage to the slider. Summary of the Invention
[0004] The present invention aims to solve the various problems mentioned above, and thereby provide a novel pressureless locking sliding door for oxygen chambers.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0018] This utility model discloses a novel pressureless locking sliding door for oxygen chambers. It features a simple structure, stable and reliable operation, and easy maintenance. The door panel slides left and right and moves forward and backward via a sliding assembly and a locking assembly, respectively. Both assemblies utilize pulleys and rails, effectively solving the problems of complex structure, high failure rate, difficult maintenance, and stress issues between components associated with traditional sliding devices compared to the latter. This significantly reduces the failure rate, size, and weight of the device, resulting in more precise sliding and locking of the door panel with less resistance. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings.
[0030] Example 1
[0031] A novel pressureless locking sliding door for an oxygen chamber includes a door panel 1, a door sliding assembly 2 and a door locking assembly 3 connected to the upper part of the door panel 1, and a roller 4, a lower slide rail 5, a cylinder 7 and a pneumatic control lever 6 connected to the lower part of the door panel 1. The left and right sliding of the door panel 1 is achieved by the cooperation of the upper door sliding assembly 2 and the lower roller 4 and lower slide rail 5. The locking function of the door panel 1 in the front and back directions is achieved by the cooperation of the door locking assembly 3, the cylinder 7 and the pneumatic control lever 6.
[0032] The specific composition of the door sliding assembly 2 and the door locking assembly 3 will be described in detail below.
[0033] The door sliding assembly 2 includes a door panel connecting seat 21, a pulley assembly 22 mounted on the door panel connecting seat 21, and left and right sliding rails 23 adapted to and connected to the pulley assembly 22. The door panel connecting seat 21 includes a base plate 21a fixed to the top of the door panel 1, and two ear plates 21b erected on the base plate 21a. Each ear plate 21b has a pair of mounting holes, and pulleys 21c are installed on the front and rear sides of the ear plate 21b respectively using bolts and locking devices. The left and right sliding rails 23 include a pair of opposing C-shaped channel steels 23a, and a connecting plate 23b on the top of the two C-shaped channel steels 23a for fixing them together. The ear plates 21b are positioned between the two C-shaped channel steels 23a, and the pulleys 21c on the front and rear sides of the ear plates 21b are slidably adapted to the interiors of the two C-shaped channel steels 23a of the left and right sliding rails 23.
[0034] During the opening and closing of the door, the door panel 1 will drive the door panel connecting seat 21 and the pulley group 22 above it to slide along the sliding groove of the left and right sliding rails 23 at the top. At the same time, the roller 4 at the bottom of the door panel 1 slides along the lower sliding rail 5, thereby realizing the movement of the door panel 1 in the left and right directions, thus realizing the opening or closing of the door.
[0035] The door locking assembly 3 includes a locking seat 31, a pulley assembly 32 mounted on the locking seat 31, and front and rear slide rails 33 adapted to and connected to the pulley assembly 32. The locking seat 31 includes a base plate 31a mounted on the left and right slide rails 23, and two ear plates 31b erected on the base plate 31a. Each ear plate 31b has a pair of mounting holes, and pulleys 31c are mounted on the left and right sides of the ear plate 31b respectively using bolts and locking components. The front and rear slide rails 33 include a pair of opposing C-shaped channel steels 33a, and a connecting plate 33b on the top of the two C-shaped channel steels 33a for fixing them together. The ear plates 31b are positioned between the two C-shaped channel steels 31c, and the pulleys 31c on the left and right sides of the ear plates 31b are slidably adapted to the interiors of the two C-shaped channel steels 33a of the front and rear slide rails 33.
[0036] The door locking assembly 3 also includes a pneumatic control component 34, which consists of a cylinder fixing plate 34a, a cylinder 34b fixed on the cylinder fixing plate 34a, and a drive plate 34c connected by the push rod of the cylinder 34b. The drive plate 34c is sleeved and fixed on the bolt between the two ear plates 31b.
[0037] When door panel 1 slides to the closed position, cylinder 34b activates, and its push rod drives pulley assembly 32 to slide within the front and rear slide rails 33 via drive plate 34c, thereby pulling the entire door panel 1 to achieve locking in the front and rear directions. During the cabin pressurization and locking process, the lower cylinder 7 pushes the pneumatic control lever 6 to one side of door panel 1, thereby cooperating with the upper door locking assembly 3 to firmly press door panel 1 onto the door frame, thus achieving a seal.
