Technical Field

[0001] This utility model relates to the field of glove box equipment technology, and in particular to a quick-change glove receiving tray for a sealed box. Background Technology

[0002] When using glove box equipment, the glove receiving tray is a crucial component. Chinese patent application number 202120208248.2 discloses a quick-change glove receiving tray in a sealed chamber, comprising a box body and an operating table. Windows are provided on the inner sides of both the left and right end faces of the box body. The operating table is fixedly connected to the inner side of the bottom end face of the box body. A transparent plate is fixedly connected to the center of the top end face of the box body. Lights are fixedly connected to the inner sides of the left and right end faces of the box body. A first sealing ring is slidably connected to the left end face of the box body. A fixing ring is fixedly connected to the outer side of the first sealing ring. A handle is fixedly connected to the left end face of the fixing ring. A thread is fixedly provided on the outer side of the fixing ring, and the thread is rotatably connected to the box body. The inner side of the left end face of the box body is slidably connected to... The box has a placement ring that is slidably connected to the box body. A glove is slidably connected to the outer side of the placement ring and is slidably connected to a fixing ring. A retaining ring is fixedly connected to the inner side of the top surface of the glove and is slidably connected to the fixing ring. A second sealing ring is fixedly connected to the outer side of the placement ring and is slidably connected to the fixing ring. A hydraulic rod is connected to the inner side of the left end face of the box body. A connecting plate is fixedly connected to the front end face of the hydraulic rod located at the rear end. A sealing sheet is fixedly connected to the front end face of the connecting plate located at the front end. A spring is fixedly connected to the front end face of the connecting plate located at the front end. A push block is fixedly connected to the other end of the spring. A jog switch is fixedly connected to the inner side of the left end face of the box body and is slidably connected to the push block. A controller is fixedly connected to the top surface of the box body.

[0003] Although the above-mentioned technology can disassemble the glove by turning the handle to rotate the fixing ring and thus detaching it from the box and the retaining ring, and by pulling the retaining ring to detach the glove from the placement ring, it still has the drawbacks of multiple steps and cumbersome operation in actual use. Therefore, in order to solve the problem of not being able to quickly change gloves when using the above-mentioned technology, we propose a quick-change glove tray for a sealed box. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sealed chamber quick-change glove tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-change glove tray for a sealed chamber includes a base and a fixing seat mounted on an external glove box. The front side of the base is provided with an annular mounting plate, and a glove is mounted on the inner side of the mounting plate. A sealing ring is provided between the mounting plate and the base. A pressing frame is rotatably mounted on the front side of the fixing seat via a linkage shaft. The end of the pressing frame away from the linkage shaft is attached to the front side of the mounting plate. A worm gear is mounted on one end of the linkage shaft, and a worm corresponding to the worm gear is mounted on one end of the fixing seat. A positioning component is provided on the end of the linkage shaft away from the worm gear.

[0007] Preferably, the positioning component includes a pointer and a scale pattern. The scale pattern is disposed on the end face of the fixed base, one end of the pointer is mounted on the end of the linkage shaft, and the other end of the pointer cooperates with the scale pattern.

[0008] Preferably, a roller is installed at the end of the pressing frame away from the fixed base, and the pressing frame contacts the mounting plate through the roller.

[0009] Preferably, the front side of the base is threaded with an installation ring, and the front side of the installation ring is provided with a matching installation groove corresponding to the sealing ring.

[0010] Preferably, the outer ring surface of the mounting ring is provided with a plurality of force-applying holes, which are distributed circumferentially with the axis of the mounting ring as the center.

[0011] Preferably, the sealing ring has a protrusion extending to both sides on one side of the mounting plate, and the protrusion is located where the mounting ring contacts the mounting plate and the base.

[0012] Preferably, the mounting ring has a plurality of positioning rods at its edge, and the mounting plate has a corresponding positioning groove for each positioning rod.

[0013] The beneficial effects of the quick-change glove tray for sealed chambers proposed in this utility model are as follows:

[0014] 1. In this utility model, a rotating worm gear drives a linkage shaft to rotate via a worm wheel. This linkage shaft causes the pressing frame to disengage from or press against the mounting plate. Thus, the glove replacement can be completed very quickly through the separation and engagement of the pressing frame and the mounting plate. Compared with traditional solutions, this solution only requires one step to complete the glove replacement, effectively improving the replacement efficiency. Furthermore, the positioning component allows personnel to accurately and quickly determine whether the gloves are securely installed and whether the seal is in place during installation. Therefore, this solution can better guarantee the installation effect compared to traditional solutions.

[0015] 2. The positioning component in this invention allows the pointer to rotate synchronously via the linkage shaft when the pressing frame rotates. This allows personnel to judge the rotation angle of the pressing frame by observing the scale markings on the pointer, thus determining the degree of pressure exerted by the pressing frame on the mounting plate. This avoids situations where personnel cannot accurately judge the pressure applied by the pressing frame, resulting in insufficient or excessive force on the mounting plate. This ensures that the mounting plate provides a relatively effective seal to the base through the sealing ring. The rollers reduce wear between the pressing frame and the mounting plate. The mounting ring allows for convenient replacement of the sealing ring after it is securely installed. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A quick-change glove tray for a sealed chamber includes a base 1 and a fixing seat 2 mounted on an external glove box. The front side of the base 1 is provided with an annular mounting plate 3, and a glove 4 is mounted on the inner side of the mounting plate 3. A sealing ring 5 is provided between the mounting plate 3 and the base 1. A pressing frame 7 is rotatably mounted on the front side of the fixing seat 2 via a linkage shaft 6. The end of the pressing frame 7 away from the linkage shaft 6 is attached to the front side of the mounting plate 3. A worm gear 8 is mounted on one end of the linkage shaft 6, and a worm 9 corresponding to the worm gear 8 is mounted on one end of the fixing seat 2. A positioning component is provided on the end of the linkage shaft 6 away from the worm gear 8.

[0026] Example 2

[0027] Reference Figure 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0028] The positioning component includes a pointer 10 and a scale. The scale is set on the end face of the fixed base 2. One end of the pointer 10 is installed at the end of the linkage shaft 6, and the other end of the pointer 10 cooperates with the scale. The positioning component allows the pointer 10 to rotate synchronously through the linkage shaft 6 when the pressing frame 7 rotates. Thus, the operator can judge the rotation angle of the pressing frame 7 by the scale data pointed to by the pointer 10, that is, judge the degree of compression of the pressing frame 7 on the mounting plate 3. This avoids the phenomenon that the operator cannot accurately judge the pressure applied by the pressing frame 7, resulting in the mounting plate 3 being subjected to too little or too much force. This ensures that the mounting plate 3 can provide a more effective sealing effect to the base 1 through the sealing ring 5. A roller 11 is installed at the end of the pressing frame 7 away from the fixed base 2. The pressing frame 7 contacts the mounting plate 3 through the roller 11. The roller 11 reduces the wear between the pressing frame 7 and the mounting plate 3.

[0029] A mounting ring 12 is threaded onto the front side of the base 1. The front side of the mounting ring 12 has a corresponding mounting groove for the sealing ring 5. The outer surface of the mounting ring 12 has several force-applying holes 13, distributed circumferentially around the axis of the mounting ring 12. The side of the sealing ring 5 that contacts the mounting plate 3 has protrusions 14 extending to both sides. These protrusions 14 are located where the mounting ring 12 contacts the mounting plate 3 and the base 1. Several positioning rods 15 are provided at the edge of the mounting ring 12. The mounting plate 3 has corresponding positioning grooves for the positioning rods 15. The mounting ring 12 ensures a secure mounting of the sealing ring 5. After installation, the sealing ring 5 can be easily replaced by replacing the installation ring 12. The force-applying hole 13 allows personnel to easily install and remove the installation ring 12 using external tools such as force-applying rods. The protrusion 14 of the sealing ring 5 improves the sealing between the mounting plate 3, the base 1, and the installation ring 12. The positioning rod 15 ensures that the mounting plate 3 maintains a certain degree of connection stability with the base 1 when it is not constrained by the pressing frame 7, making it easy for personnel to install and remove the mounting plate 3.

[0030] Operating principle and advantages: In use, the front end of the glove is connected to the mounting plate 3, while the tail end is placed inside the glove box. When a person needs to quickly change the glove, they can directly rotate the worm gear 9. The worm gear 9 drives the linkage shaft 6 to rotate through the worm wheel 8. The linkage shaft 6 causes the pressing frame 7 to disengage from the mounting plate 3 or to press it. When the pressing frame 7 disengages from the mounting plate 3, the person can directly pull the mounting plate 3 off the front side of the base 1 and replace it with a new mounting plate 3, which means replacing the glove. When the new glove is placed in the glove box, i.e., when the new mounting plate 3 is attached to the front side of the base 1, the person controls the pressing frame 7 to rotate towards the mounting plate 3 until the end of the pressing frame 7 presses the mounting plate 3, causing the mounting plate 3 to move towards the base 1. At this time, the mounting plate 3 and the sealing ring 5 clamped on the side seal the base 1, thus completing the glove replacement.

[0031] In summary, this solution allows for rapid glove replacement by separating and connecting the pressing frame 7 and the mounting plate 3. Compared to traditional solutions, this solution requires only one step to replace the gloves, effectively improving replacement efficiency. Furthermore, the positioning components allow personnel to accurately and quickly determine whether the gloves are securely installed and properly sealed during installation, ensuring better installation results compared to traditional solutions.

[0032] It should be further explained that the positioning component allows the pressing frame 7 to rotate synchronously with the pointer 10 via the linkage shaft 6 when it rotates. This allows personnel to judge the rotation angle of the pressing frame 7 by observing the scale markings on the pointer 10, thus determining the degree of pressure exerted by the pressing frame 7 on the mounting plate 3. This avoids situations where personnel cannot accurately judge the pressure applied by the pressing frame 7, resulting in insufficient or excessive force on the mounting plate 3. This ensures that the mounting plate 3 provides a relatively effective seal to the base 1 through the sealing ring 5. The roller 11 reduces wear between the pressing frame 7 and the mounting plate 3. The mounting ring 12 ensures a more effective seal. After the ring 5 is securely installed on the mounting ring 12, personnel can easily replace the sealing ring 5 by replacing the mounting ring 12. The force-applying hole 13 allows personnel to easily install and remove the mounting ring 12 using external tools such as a force-applying rod. The protrusion 14 of the sealing ring 5 improves the sealing between the mounting plate 3, the base 1, and the mounting ring 12. The positioning rod 15 ensures that the mounting plate 3 maintains a certain degree of connection stability with the base 1 when it is not constrained by the pressing frame 7, making it easy for personnel to install and remove the mounting plate 3.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
