[0026] Example 1

[0027] Please see Figure 1 and Figure 2 The present invention discloses a glove receiving tray, including a glove assembly 1, a chuck 2 and a quick-change assembly 3.

[0028] The chuck 2 is mounted on the glove box, and a receiving channel is formed through the middle of the chuck 2. The glove assembly 1 includes a glove and a clamp. The glove 13 is fixedly connected to the clamp, which engages with the receiving channel of the chuck 2 to position the glove 13 within the chuck 2. The clamp has a locking part 15 at its upper end and a pre-set groove 16 at its lower end. The quick-change assembly 3 is located above the chuck 2 and connected to the chuck 2. The quick-change assembly 3 has a hook 38 at its lower end.

[0029] like Figure 2 As shown, when changing gloves 13, the hook 38 engages with the locking part 15 of the glove assembly 1 to be replaced, and the preparation slot 16 of the glove assembly 1 to be replaced engages with the locking part 15 of the new glove assembly 1 pre-placed inside the glove box, so that the old glove assembly 1 and the new glove assembly 1 are interlocked together through the locking part 15 and the preparation slot 16. The hook 38 of the quick-change assembly 3 can move upward in a vertical direction to bring the glove assembly 1 to be replaced out of the chuck 2, and then load the new glove assembly 1 into the chuck 2.

[0030] Specifically, the new glove assembly 1 is pre-placed in the glove box. Since the new glove assembly 1 is inserted into the chuck 2 from inside the glove box, the glove receiving tray will not bring in outside air during the process of changing gloves 13.

[0031] It should be noted that the quick-change assembly 3 and the chuck 2 are detachably connected. When gloves 13 do not need to be changed, the operator can remove the quick-change assembly 3, allowing them to put on gloves 13 and operate the glove box normally. When gloves 13 need to be changed, the operator first engages the locking part 15 of the new glove assembly 1, which is pre-placed in the glove box, with the pre-slot 16 of the old glove assembly 1, thus interlocking the old and new glove assemblies. Then, the operator installs the quick-change assembly 3 onto the chuck 2, engaging the hook 38 with the locking part 15 of the old glove assembly 1, pulling the old glove assembly 1 out of the chuck 2 while simultaneously pulling the new glove assembly 1 into the chuck 2. After the change is complete, the operator can remove the quick-change assembly 3 and continue operating the glove box.

[0032] Therefore, the glove tray allows for easy replacement of gloves 13 and prevents outside air from being brought into the glove box.

[0033] Please see Figure 2 and Figure 3 In this embodiment, a V-shaped groove is formed on the side wall of the receiving channel of the chuck 2. The clamp of the glove assembly 1 is provided with an annular protrusion that extends circumferentially along the clamp. The annular protrusion is used to engage with the V-shaped groove to position the glove 13 within the receiving channel of the chuck 2.

[0034] It should be noted that during the movement of glove assembly 1 within the receiving channel of chuck 2, the annular protrusion on its outer side will rub against the sidewall of the receiving channel. To facilitate the removal of glove assembly 1 by the operator, the clamp of glove assembly 1 is made of an elastic material. Preferably, the clamp of glove assembly 1 is made of polyethylene material.

[0035] Furthermore, such as Figure 5 As shown, the clamp includes an upper clamping member 14 and a lower clamping member 11, both of which are annular. A locking portion 15 is located on the outer side of the upper end of the upper clamping member 14, and a pre-set groove 16 is located on the inner side of the lower end of the lower clamping member 11. Specifically, the diameter of the lower clamping member 11 is larger than the diameter of the upper clamping member 14, and the upper clamping member 14 is embedded within the lower clamping member 11. The upper clamping member 14 and the lower clamping member 11 can be fixed together by an interference fit.

[0036] Specifically, such as Figure 3 As shown, an annular cavity is provided between the upper clamp 14 and the lower clamp 11. Additionally, a skirt is provided at the upper end of the glove 13, and the skirt is housed within the cavity. When the upper clamp 14 and the lower clamp 11 are fixed together, the skirt of the glove 13 can be fixed between the upper clamp 14 and the lower clamp 11. The skirt of the glove 13 seals the gap between the upper clamp 14 and the lower clamp 11 and secures the glove 13 to the clamp.

[0037] Furthermore, such as Figure 3 and Figure 5 As shown, the outer side of the lower clamp 11 is also provided with a mounting groove, which is annular and extends circumferentially along the lower clamp 11. The glove assembly 1 also includes a sealing ring 12, which is housed in the mounting groove and is used to seal the gap between the inner wall of the chuck 2 and the outer wall of the lower clamp 11.

[0038] Please see Figure 4 In this embodiment, the quick-change assembly 3 includes a mounting cover 32 and a connecting base 31. Specifically, as follows... Figure 2 and Figure 3 As shown, the hook 38 is disposed on the inner side of the lower end of the connecting seat 31. The hook 38 extends inward and engages with the locking part 15. The mounting cover 32 is mounted on the chuck 2. The mounting cover 32 covers the connecting seat 31 and is connected to the connecting seat 31. It is used to drive the connecting seat 31 to move in the vertical direction, thereby bringing the glove unit out through the connecting part.

[0039] It should be noted that the mounting cover 32 is detachably connected to the chuck 2. The mounting cover 32 is only installed on the chuck 2 when the glove 13 in the chuck 2 needs to be replaced.

[0040] Furthermore, there are multiple hooks 38, each hook 38 being arc-shaped and arranged circumferentially along the inner sidewall of the connecting seat 31. For example... Figure 5 As shown, there are multiple locking parts 15, each of which is arc-shaped and arranged circumferentially along the outer side wall of the clamp. The claws 38 correspond one-to-one with the locking parts 15 and are locked onto the locking parts 15.

[0041] Specifically, the operation process of engaging the hook 38 with the engaging portion 15 is as follows: First, align the connecting seat 31 with the clamp of the glove assembly 1, and align the hook 38 with the notch between the engaging portions 15; then, move the connecting seat 31 downwards, so that the hook 38 moves from the notch between the engaging portions 15 to below the engaging portion 15; next, rotate the connecting seat 31 by a certain angle, so that the hook 38 engages with the engaging portion 15. The structure of the hook 38 engaging with the engaging portion 15 is as follows: Figure 3 As shown.

[0042] In addition, such as Figure 3As shown, the upper part of the pre-slot 16 of the glove assembly 1 has multiple notches, the shape of which matches the shape of the snap-fit ​​part 15, for the snap-fit ​​part 15 to pass through. The operation process of snapping the pre-slot 16 of the old glove assembly 1 with the snap-fit ​​part 15 of the new glove assembly 1 is as follows: First, align the snap-fit ​​part 15 of the new glove assembly 1 with the notch at the upper end of the pre-slot 16 of the old glove assembly 1. After inserting the snap-fit ​​part 15 of the new glove assembly 1 into the pre-slot 16, rotate it at a certain angle so that the snap-fit ​​part 15 of the new glove assembly 1 engages with the pre-slot 16 of the old glove assembly 1.

[0043] Furthermore, the quick-change assembly 3 also includes a linkage unit. The mounting cover 32 is connected to the connecting seat 31 via the linkage unit, which drives the connecting seat 31 to move vertically. Specifically, the linkage unit includes a handle 34 and a connecting rod 33. One end of the handle 34 is hinged to the mounting cover 32, and one end of the connecting rod 33 is hinged to the middle of the handle 34, while the other end is hinged to the connecting seat 31. During rotation, the handle 34 drives the connecting rod 33 to move vertically, thereby driving the connecting seat 31 to move vertically.

[0044] Specifically, such as Figure 4 As shown, there are two linkage units. The connecting seat 31 is connected to the connecting rod 33 via the first pin 35. The connecting rod 33 is connected to the handle 34 via the second pin 36. The handle 34 is connected to the mounting cover 32 via the third pin 37. The connecting seat 31, the mounting cover 32, the connecting rod 33, and the handle 34 form a linkage 33 slider mechanism, which allows the connecting seat 31 to slide up and down inside the mounting cover 32 via the handle 34.

[0045] The process for receiving these gloves is as follows: (e.g., ...) Figure 2 , Figure 3 As shown, under normal operating conditions, glove assembly 1 is locked in chuck 2, positioned and secured by annular protrusions and V-shaped grooves. Workers operate the equipment inside the glove box through glove 13.

[0046] When glove 13 needs to be changed, the worker retrieves a spare new glove from the glove box using the old glove, pulls a portion of the new glove assembly 1 into the chuck 2, and rotates it at a certain angle so that the upper locking piece 14 engages with the lower locking piece 11 of the old glove assembly 1. Then, the quick-change tool is placed on the chuck 2 and rotated at a certain angle so that the hook 38 engages with the upper locking piece 14. At this point, the quick-change tool is supported on the chuck 2 and interlocked with the glove assembly 1 via the hook 38. The old glove assembly 1 and the new glove assembly 1 are interlocked via the locking part 15 and the pre-set slot 16. Finally, the handle 34 is pulled up to remove the glove assembly 1 from the chuck 2, while simultaneously pulling the new glove assembly 1 into the chuck 2. This completes the glove assembly 1 replacement operation.

[0047] In summary, this glove receiving tray has the following advantages: it enables rapid glove replacement; and it allows replacement from inside the glove box, preventing external gases from entering the glove box and disrupting the internal atmosphere.

[0048] Example 2

[0049] Please see Figure 2 The present invention also discloses a glove box, including a box body and a glove receiving tray as described in Embodiment 1.

[0050] The glove receiving tray is installed on the box body for securing gloves, and the box body contains multiple spare new glove assemblies 1.

[0051] When gloves need to be changed, the worker retrieves a spare new glove assembly 1 from the glove box using the old glove 13. The upper clip 14 of the new glove assembly 1 is then engaged with the lower clip 11 of the old glove assembly 1. Next, the quick-change tool is engaged in the chuck 2, with the claw 38 engaging with the upper clip 14. Finally, the handle 34 of the quick-change tool is pulled up, removing the old glove assembly 1 from the chuck 2 while simultaneously pulling the new glove assembly 1 into the chuck 2. This completes the replacement of glove assembly 1.

[0052] Furthermore, the glove box is equipped with a pre-feed chamber, where items are transferred into the glove box after atmosphere replacement. Inside the glove box is a storage box for storing new gloves. Once the gloves in the storage box are used up, new gloves are transferred back into the storage box via the pre-feed chamber.

[0053] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
