Description

Technical Field

[0001] This utility model relates to the field of gas conveying equipment technology, and in particular to a purging gas rack. Background Technology

[0002] A gas delivery rack (hereinafter referred to as a gas rack, abbreviated as GR) is an open-type process gas source delivery device used to deliver high-purity inert gas from cylinders to the downstream gas distribution unit. To ensure the continuity of gas supply, the gas rack usually adopts a "one in use, one standby" working mode. When one cylinder of gas is exhausted, it is necessary to switch and replace another cylinder. According to the degree of automation, the gas rack can be divided into two types: semi-automatic and manual. The semi-automatic type can maintain the gas supply during cylinder replacement to avoid downstream process interruption.

[0003] However, the traditional gas racks currently in use have obvious defects in the process of changing gas cylinders. Due to the large weight of the gas cylinders and the limited operating space inside the rack, operators often have to lift or drag the gas cylinders out of the rack by hand. This operation is not only labor-intensive and inefficient, but also poses a high safety risk. For example, the gas cylinders are prone to tipping over or slipping during the handling process due to unstable grip, which may cause serious consequences such as personnel injury, valve damage, or even gas leakage.

[0004] Therefore, given the problems of laborious operation, high risk and low efficiency in the existing gas cylinder replacement process, it is urgent to optimize and improve its structure. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a purge gas holder to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a purge gas frame, including a frame body, and the frame further includes:

[0007] At least one sliding tray for supporting the bottom of the gas cylinder;

[0008] A fixing mechanism, which is disposed on the sliding tray, is used to restrict the movement of the gas cylinder relative to the sliding tray when the sliding tray carries the gas cylinder and moves relative to the frame;

[0009] A linear guide mechanism is provided between the sliding tray and the frame to constrain the sliding tray to extend or retract relative to the frame along a preset trajectory;

[0010] A movement assist mechanism, which is connected to the sliding tray, is used to reduce the movement resistance of the sliding tray when it is moved by an external force;

[0011] A locking mechanism is provided for releasably fixing the sliding tray relative to the frame when the sliding tray moves to a predetermined position on the frame.

[0012] As a preferred embodiment of this utility model, the fixing mechanism includes:

[0013] A first limiting plate is disposed on the sliding tray;

[0014] At least one fixing part connected to the first limiting plate, the fixing part includes a first hoop, one end of the first hoop is connected to a second hoop by a hinge, the ends of the first hoop and the second hoop away from the hinge are detachably fixedly connected by a latch, and when the first hoop and the second hoop are closed, they can form a limiting space to hold the gas cylinder and prevent its movement.

[0015] As a preferred embodiment of this utility model, the linear guide mechanism includes a slider disposed on the side wall of the sliding tray, and the frame is provided with a bottom plate with a groove at its bottom, the groove being adapted to the shape of the slider and the sliding tray.

[0016] As a preferred embodiment of this utility model, the moving auxiliary mechanism consists of rollers rotatably mounted on the bottom of the sliding tray, with each sliding tray having at least three rollers on its bottom to provide support for the sliding tray.

[0017] As a preferred embodiment of this utility model, the locking mechanism includes:

[0019] A pin is located on the other side of the slide groove;

[0020] A baffle with a second threaded hole at one end and the other end of the baffle is rotatably connected to a pin. When the baffle is rotated to abut against the bracket, the first threaded hole and the second threaded hole are aligned and obstruct the extension of the sliding tray.

[0021] Bolts are used to simultaneously pass through the first threaded hole and the second threaded hole to prevent the baffle from rotating.

[0022] As a preferred embodiment of this utility model, the sliding tray is connected to a push handle, and the surface of the push handle is provided with an anti-slip structure to provide an anti-slip function when held.

[0023] As a preferred embodiment of this utility model, the edge of the sliding tray is formed with an angle to reduce friction or scratches between the gas cylinder and the sliding tray during the transfer process.

[0024] As a preferred embodiment of this utility model, the base plate is provided with at least two sliding grooves, and correspondingly, the sliding tray and the gas cylinder have at least two of each.

[0025] The frame is provided with at least one second limiting plate with a limiting groove. When the sliding tray enters the predetermined position of the frame, the gas cylinder fits into the limiting groove, thereby cooperating with the first limiting plate to form a bidirectional positioning.

[0026] The beneficial effects of this utility model are as follows: By unlocking and locking the mechanism, the operator can pull the sliding tray from the outside.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] like Figure 1 and Figure 2 As shown, a purge gas support includes a frame 1, at least one sliding tray 4 for supporting the bottom of a gas cylinder; a fixing mechanism disposed on the sliding tray 4 for restricting the movement of the gas cylinder relative to the sliding tray 4 when the sliding tray 4 carries the gas cylinder and moves relative to the frame 1; a linear guiding mechanism disposed between the sliding tray 4 and the frame 1 for constraining the sliding tray 4 to extend or retract relative to the frame 1 along a preset trajectory; a movement assist mechanism connected to the sliding tray 4 for reducing the movement resistance of the sliding tray 4 when it is driven by an external force; and a locking mechanism for releasably fixing the sliding tray 4 relative to the frame 1 when the sliding tray 4 moves to a predetermined position.

[0036] The above technical solution is labor-saving, efficient, and can greatly avoid safety accidents such as gas cylinder tipping or personnel injury caused by improper handling. Specifically, during operation, the locking mechanism is unlocked, and the operator pulls the sliding tray 4 outward. The moving auxiliary mechanism converts sliding friction into rolling friction, so that the sliding tray 4 can easily slide out of the frame 1 along the preset trajectory of the linear guide mechanism. The fixing mechanism restricts the gas cylinder from shaking or tipping throughout the process, solving the problem that traditional gas cylinder racks require operators to laboriously carry or lift heavy gas cylinders out of the frame 1.

[0037] like Figure 2 and Figure 4As shown, in this embodiment, the fixing mechanism includes: a first limiting plate 7, which is disposed on the sliding tray 4; at least one fixing part connected to the first limiting plate 7, the fixing part including a first hoop 8, one end of the first hoop 8 is connected to a second hoop 9 through a hinge 10, the ends of the first hoop 8 and the second hoop 9 away from the hinge 10 are detachably fixedly connected by a latch 11, when the first hoop 8 and the second hoop 9 are closed, they can form a limiting space to hold the gas cylinder to prevent its movement, and at least one second limiting plate 12 with a limiting groove 13 is provided in the frame 1;

[0038] The above technical solution enables the rapid and reliable fixing and release of gas cylinders. In use, the gas cylinder is placed next to the first limiting plate 7 on the sliding tray 4, so that the gas cylinder and the first hoop 8 are in close contact. The second hoop 9 is rotated to surround the gas cylinder body, and then the locking buckle 11 is closed to firmly bind the gas cylinder in the formed limiting space. Its working principle is to constrain the gas cylinder from all sides through the openable clamp structure. This design solves the problems of cumbersome operation, difficulty in adjustment and weak binding of traditional chain or strap fixing methods. Moreover, when the sliding tray 4 enters the predetermined position of the frame 1, the gas cylinder and the limiting groove 13 are in contact, thereby forming a two-way positioning with the first limiting plate 7, which further improves the convenience and safety of operation.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the linear guide mechanism includes a slider, which is disposed on the side wall of the sliding tray 4. The frame 1 has a bottom plate 2 with a groove 3 at its bottom, and the groove 3 is adapted to the shape of the slider and the sliding tray 4.

[0040] The above technical solution can ensure that the gas cylinder can be delivered or retrieved smoothly and straight, with a precise and reliable movement trajectory. The working principle is to use the sliding block set on the side wall of the sliding tray 4 to cooperate with the sliding groove 3 on the bottom plate 2 of the frame 1. When the sliding tray 4 is pulled, the sliding block slides in the sliding groove 3. The working principle is to use the cooperation pair of the sliding block and the sliding groove 3 to strictly constrain the movement path of the sliding tray 4 and avoid the sliding tray 4 from deviating, jamming or tilting during the movement.

[0041] like Figure 4 As shown, in this embodiment, the movement assistance mechanism is a roller 5 that is rotatably disposed at the bottom of the sliding tray 4. Each sliding tray 4 has at least three rollers 5 at its bottom to provide support for the sliding tray 4.

[0042] The above technical solution allows operators to push heavy gas cylinders with very little force by rotating the rollers 5. When the sliding tray 4 is subjected to external force, the rollers 5 begin to roll. The working principle is to replace sliding friction with rolling friction. The support system consisting of at least three rollers 5 ensures the stability of the tray.

[0043] like Figure 3 As shown, in this embodiment, the locking mechanism includes: a bracket 16 with a first threaded hole 17, the bracket 16 being fixedly mounted on one side of the slide groove 3; a pin 14, which is mounted on the other side of the slide groove 3; a baffle 15 with a second threaded hole 18 at one end, the other end of the baffle 15 being rotatably connected to the pin 14, when the baffle 15 rotates to abut against the bracket 16, the first threaded hole 17 and the second threaded hole 18 are aligned, thus hindering the extension of the sliding tray 4; and a bolt 19, which is used to simultaneously pass through and connect the first threaded hole 17 and the second threaded hole 18 to prevent the baffle 15 from rotating.

[0044] The above technical solution can prevent the sliding tray 4 from accidentally detaching from the slide groove 3. When the sliding tray 4 needs to be locked, it is pushed back into the frame 1 and the baffle 15 is rotated to make it abut against the bracket 16. At this time, the first threaded hole 17 and the second threaded hole 18 are aligned, and the bolt 19 is screwed in to lock it, forming a mechanical interlock.

[0045] like Figure 2 As shown, in this embodiment, the sliding tray 4 is connected to a push handle 6. The surface of the push handle 6 is provided with an anti-slip structure to provide an anti-slip effect when held. The anti-slip structure can be an anti-slip texture.

[0046] The above technical solution makes applying force more convenient, comfortable and effective, further reducing the difficulty of operation and labor intensity. When in use, the operator applies pulling or pushing force by holding the push handle 6 to drive the sliding tray 4. The anti-slip structure on its surface increases the friction between the hand and the push handle 6, solving the problem of not having a place to hold and being prone to slipping when directly pushing or pulling the edge of the tray.

[0047] like Figure 2 and Figure 4 As shown, in this embodiment, the edge of the sliding tray 4 is formed with a chamfer 20 to reduce friction or scratches between the gas cylinder and the sliding tray 4 during the transfer process.

[0048] The above technical solution can improve the safety of loading and unloading gas cylinders. By chamfering or rounding the corners, the sharp right-angled edges can be prevented from scratching the surface of the gas cylinder, thus avoiding damage to the gas cylinder.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, at least two sliding grooves 3 are provided on the base plate 2, and correspondingly, at least two sliding trays 4 and gas cylinders are provided to achieve one for backup and one for use.

[0050] The above-mentioned technical solution improves the space utilization and equipment functionality. During operation, at least two sliding grooves 3 on the base plate 2 allow two or more sliding trays 4 to independently carry gas cylinders and slide independently. Its working principle is to use a parallel multi-track design to support multiple gas cylinder units, realizing the integrated storage of multiple gas cylinders in a compact frame 1, and the ability to flexibly pick up and put down any gas cylinder as needed.

[0052] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
