Description

Technical Field

[0001] This utility model relates to the field of glove interface technology, specifically to a glove box glove interface sealing mechanism. Background Technology

[0002] Glove boxes, as important closed-loop operating equipment, are widely used in fields such as chemistry, materials science, and nuclear industry to handle materials sensitive to air or moisture in inert gas or vacuum environments. Glove boxes isolate operators from the internal environment through glove interfaces, and the sealing performance of these interfaces directly affects the stability of the internal environment and the safety of operation.

[0003] In the existing technology, when it is necessary to change gloves, the existing design has the following problems:

[0004] During glove changing, the glove openings often cannot be completely closed, leading to rapid exchange of gases between the chamber and the external environment. This not only causes fluctuations in the chamber's air pressure but may also introduce contaminants such as oxygen and moisture, affecting the stability of the experimental or production process.

[0005] Because gloves cannot be effectively sealed when changed, the air pressure or environmental parameters (such as oxygen concentration and humidity) inside the chamber may change significantly, requiring additional time and resources to readjust the environment inside the chamber, which increases the cost of use.

[0006] In response to the aforementioned problems, we propose a glove box glove interface sealing mechanism. Utility Model Content

[0009] A glove box glove interface sealing mechanism includes a glove box, a flange extending through the box wall of the glove box, the inner end of the flange extending into the box and the outer end extending out of the box; a locking ring and a glove fixing ring sequentially fitted onto the flange on the outside of the glove box; a guide groove provided on the portion of the flange located inside the glove box, a rotatable baffle provided in the guide groove; a sliding groove formed along the edge of the baffle on the inner side of the flange, a lever connected to the baffle provided in the sliding groove, a moving rod provided at the end of the sliding groove, and a magnet provided in the baffle.

[0010] Furthermore, sealing rings are provided on the contact surfaces of the flange and glove box, the locking ring and glove box, and the baffle and flange.

[0011] Furthermore, both the locking ring and the glove retaining ring are connected to the outer end of the flange via threads.

[0012] Furthermore, the opening of the guide groove faces downwards, and the baffle can fall naturally when the lever is rotated due to gravity.

[0013] Furthermore, the baffle is placed in the guide groove, and a gap is reserved between the edge of the baffle and the inner wall of the guide groove. The slide is a 180° arc groove and is set along the edge of the baffle.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See attached document Figures 1-9 ,

[0029] In this embodiment, a glove box glove interface sealing mechanism includes a glove box, wherein a flange 1 is provided through the wall of the glove box, the inner end of the flange 1 extends into the box, and the outer end extends out of the box; a locking ring 2 and a glove retaining ring 3 are provided on the outside of the glove box, which are sequentially sleeved on the flange 1, and both the locking ring 2 and the glove retaining ring 3 are threadedly connected to the outer end of the flange 1.

[0030] The flange 1 located inside the glove box has a guide groove 11 with its opening facing downwards. The baffle 5 can fall naturally when the lever 6 is rotated due to gravity. The guide groove 11 has a rotatable baffle 5 inside it. The baffle 5 is placed inside the guide groove 11, and a gap is reserved between the edge of the baffle 5 and the inner wall of the guide groove 11. The slide groove 12 is a 180° arc groove set along the edge of the baffle 5. The inner side of the flange 1 has a slide groove 12 along the edge of the baffle 5. The slide groove 12 has a lever 6 connected to the baffle 5 inside it. The lever 6 slides in the slide groove 12. The lever 6 is hinged to the baffle 5 by a pin. The end of the slide groove 12 also has a moving rod 7. The baffle 5 has a magnet inside it, and the moving rod 7 is made of a metal material that can be attracted by the magnet.

[0031] The movable rod 7 extends a set distance from the flange 1. The movable rod 7 is slidably engaged with the flange 1. The movable rod 7 is parallel to the plane of the baffle 5 and its end is attracted to the magnet embedded in the baffle 5. The contact surface between the flange 1 and the glove box, the contact surface between the locking ring 2 and the glove box, and the contact surface between the baffle 5 and the flange 1 are all provided with sealing rings 4.

[0032] Working principle: During the closing process of baffle 5, the operator rotates lever 6 clockwise. Lever 6 slides smoothly along the 180° arc-shaped slide groove 12, driving baffle 5 to rotate and rise through the pin hinge structure. The downward-facing design of the guide groove 11 ensures precise and controllable movement trajectory. When baffle 5 is nearly fully closed, the embedded magnet and the end of the moving rod 7 enter the effective adsorption range. Then, the moving rod 7 is pushed close to the magnet. Under the restriction of the displacement of the moving rod 7 by the flange 1, baffle 5 quickly completes the closing movement. The moving rod 7 and the magnet complete the adsorption, forming a rigid lock. The sealing ring 4 at the contact surface between baffle 5 and flange 1 is completely pressed. Then, the glove fixing ring 3 is removed, and a new glove is replaced.

[0033] During the opening process of baffle 5, after the new gloves are fully installed, the operator pulls out the moving rod 7 to separate the magnet from the magnetic force of the moving rod 7. Then, the lever 6 is rotated counterclockwise. The lever 6 continues to move, causing baffle 5 to rotate and move around the pin. Under its own weight, baffle 5 accelerates to the open position, and then the glove interface is fully opened.
