Description

Technical Field

[0001] This invention relates to the field of glove boxes, and more particularly to an emergency device and glove box for changing gloves in a glove box. Background Technology

[0002] Metal precursor compounds are easily oxidized and hydrolyzed under external conditions, making the synthesis and purification of precursor materials extremely difficult. A glove box, also known as an inert gas handling chamber, effectively solves these problems. This device allows for the safe placement and removal of test samples and ensures normal reaction processes in an oxygen- and anhydrous environment, guaranteeing the proper execution of synthesis and purification. While the glove box uses rubber gloves that are resistant to acids and alkalis, some solvents can corrode the gloves, or improper use can cause cracks. Furthermore, the products inside the glove box are highly flammable and prone to explosion when exposed to moisture and oxygen in the air.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an emergency device for changing gloves in a glove box, which can isolate the atmosphere inside the glove box from the external environment when changing gloves, thereby ensuring personnel safety and reducing risks.

[0005] To achieve the above objectives, embodiments of the present invention provide an emergency device for changing gloves in a glove box, comprising:

[0006] Cover;

[0007] Abutment components;

[0008] An elastic element connects the cover and the abutment component;

[0009] A sealing element is installed on the cover body on the side facing the abutment assembly.

[0010] In one or more embodiments of the present invention, the abutting assembly includes a base connected to the elastic member, and a plurality of abutting members are movably mounted on the surface of the base facing the cover.

[0011] In one or more embodiments of the present invention, a limiting groove is provided on the surface of the base facing the cover, and a portion of the abutting member is movably installed in the limiting groove.

[0012] In one or more embodiments of the present invention, a pin is installed on the opposite sidewall of the limiting groove, and the abutment is rotatably mounted on the pin.

[0013] In one or more embodiments of the present invention, the cover body has a receiving cavity, and the side of the cover body opposite to the abutment component is provided with an air inlet and an air outlet communicating with the receiving cavity.

[0014] In one or more embodiments of the present invention, both the air inlet and the air outlet are detachably fitted with sealing plugs.

[0015] In one or more embodiments of the present invention, the sealing plug is partially located within the receiving cavity.

[0016] In one or more embodiments of the present invention, the sealing element is a sealing gasket.

[0017] In one or more embodiments of the present invention, the cover is provided with a connecting groove, and a portion of the sealing element is sealed and installed in the connecting groove.

[0018] Embodiments of the present invention also provide a glove box, comprising:

[0019] The housing contains a working chamber.

[0030] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0031] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0032] like Figure 1 and 3 As shown, the glove box according to a preferred embodiment of the present invention includes a box body 1, a glass plate 2, a connector 3, and an emergency device 4; the box body 1 has a working chamber 11; the glass plate 2 is mounted on the box body 1, and the glass plate 2 is provided with mounting holes 21; the connector 3 is installed at the mounting holes 21 of the glass plate 2 for connecting gloves; at least part of the emergency device 4 for changing gloves in the glove box is located in the working chamber 11.

[0033] Understandably, connector 3 is typically a metal glove ring, and the glove has an aluminum glove ring that connects to connector 3, thus sealing the glove onto the glove box. Glass plate 2 is installed on the box body 1, sealing the working chamber 11, thus placing the working chamber 11 in a closed state. This allows operators to conduct experiments or procedures requiring a high level of environmental control (e.g., anhydrous and oxygen-free conditions) within the working chamber 11. Mounting hole 21 communicates with the working chamber 11.

[0034] like Figures 1-3 As shown, the emergency device 4 for changing gloves in a glove box according to the present invention includes a cover 41, an abutment component 42, an elastic element 43, and a sealing element 44; the elastic element 43 is connected between the cover 41 and the abutment component 42; the sealing element 44 is installed on the side of the cover 41 facing the abutment component 42.

[0035] Understandably, when not in use, the emergency device 4 is generally placed inside the working chamber 11. When it is necessary to change gloves, the cover 41 can be placed inside the working chamber 11 over the mounting hole 21 on the glass plate 2 (the mounting hole 21 corresponding to the glove to be changed). To ensure that the atmosphere inside the working chamber 11 is isolated from the outside, the cover 41 can be considered to cover the mounting hole 21, that is, the projection of the cover 41 on the glass covers the mounting hole 21, and the size of the cover 41 is larger than the size of the mounting hole 21. When the cover 41 is placed over the mounting hole 21, the sealing element 44 is sealed and clamped between the glass plate 2 and the cover 41, and along the radial direction of the mounting hole 21, the sealing element 44 installed on the cover 41 is arranged around the outside of the mounting hole 21, thereby isolating the mounting hole 21 from the working chamber 11. The user controls the abutment component 42 to be outside the glass plate 2 and abut against the connector 3, and the elastic member 43 is in a stretched state, so that the sealing member 44 on the cover 41 can be driven to press against the inner surface of the glass plate 2.

[0036] Specifically, the sealing element 44 is a sealing gasket. When the cover 41 is placed over the mounting hole 21, the sealing element 44 is clamped between the glass plate 2 and the cover 41, and along the radial direction of the mounting hole 21, the sealing element 44 installed on the cover 41 is arranged around the outside of the mounting hole 21.

[0037] like Figure 2 and 3 As shown, the cover 41 may be provided with a groove for installing the seal 44. The seal 44 may be interference-fitted with the groove or may be bonded to the inner wall of the groove.

[0038] In one specific embodiment, the elastic element 43 can be a tension spring.

[0039] like Figures 2-4As shown, in one specific embodiment, the abutting component 42 includes a base 421 connected to the elastic member 43, and a plurality of abutting members 422 are movably mounted on the surface of the base 421 facing the cover 41. The abutment 422 is movably installed on the base 421 to facilitate the separation of the abutment component 42 from the connector 3. That is, when the abutment component 42 abuts against the connector 3, one end of the abutment 422 abuts against the connector 3, and the other end abuts against the surface of the base 421 facing the cover 41. The abutment 422 is installed on the base 421, thereby achieving the abutment between the abutment component 42 and the connector 3. Then, the user changes gloves. After the gloves are changed, the abutment component 42 is moved away from the cover 41, and the part of the abutment component 422 that abuts against the connector 3 is rotated towards the cover 41 to retract the abutment component 422 (this process is similar to the process of retracting the umbrella frame). Then, the abutment component 42 is moved towards the cover 41, and the abutment component 42 passes through the mounting hole 21 and enters the working chamber 11.

[0040] Furthermore, a limiting groove 4211 is protruding on the surface of the base 421 facing the cover 41, and the abutment 422 is partially movably installed within the limiting groove 4211. The limiting groove 4211 serves to restrict the movement direction of the abutment 422.

[0041] Specifically, a pin 4212 is installed on the opposite side wall inside the limiting groove 4211, and the abutment 422 is rotatably mounted on the pin 4212. The pin 4212 serves to rotatably connect the base 421 and the abutment 422.

[0042] like Figure 2 and 3 As shown in one specific embodiment, the cover 41 has a receiving cavity 411. An air inlet 412 and an air outlet 413, connected to the receiving cavity 411, are provided on the side of the cover 41 facing away from the abutment component 42. The air inlet 412 is connected to the nitrogen inlet inside the glove box, and the air outlet 413 is connected to the nitrogen outlet inside the glove box. When the emergency device 4 is in use, i.e., when the cover 41 is placed over the mounting hole 21 of the glass plate 2 and the abutment component 42 abuts against the connector 3, the receiving cavity 411 is separated from the working cavity 11, and the receiving cavity 411 is connected to the mounting hole 21. When the new gloves have not yet been changed, the valves on the nitrogen inlet and nitrogen outlet inside the glove box are closed. After the new gloves are replaced, open the valves on the nitrogen inlet and nitrogen outlet in the glove box to replace the space formed by the receiving cavity 411, the mounting hole 21 and the inside of the gloves with nitrogen, so as to ensure that the atmosphere in the above space is replaced with the atmosphere in the working cavity 11. Then remove the emergency device 4 from the glass plate 2.

[0043] Furthermore, both the air inlet 412 and the air outlet 413 are detachably fitted with sealing plugs 45. The sealing plugs 45 are detachably installed at the air inlet 412 and the air outlet 413 respectively. When there are no valves on the nitrogen inlet and the nitrogen outlet, and the new gloves have not yet been changed, the sealing plugs 45 can ensure that the receiving cavity 411 is not connected to the working cavity 11, thereby preventing external gas from contaminating the atmosphere inside the working cavity 11.

[0044] Specifically, the sealing plug 45 is partially located within the receiving cavity 411. This arrangement allows the user to seal the sealing plug 45 at the air inlet 412 and air outlet 413 from the receiving cavity 411 or to remove the sealing plug 45 from the air inlet 412 and air outlet 413.
