Description

Technical Field

[0001] This utility model relates to the field of glove box technology, specifically to a flanged transfer compartment. Background Technology

[0002] The transfer chamber is used to transfer items that need to be handled inside the glove box. The transfer chamber achieves gas replacement through vacuuming and replenishment with inert gas, effectively ensuring that the water-free and oxygen-free environment is not disrupted when transferring items into the glove box.

[0003] Currently, the circular transfer chambers used in glove boxes are usually made by fully welding a circular chamber cylinder and machined flanges at both ends. The machined flanges have certain precision requirements and the processing cost is relatively high. In addition, full welding requires experienced welders to complete the work, because everyone's welding habits and skill levels are different, and the welded transfer chambers have a certain leakage rate. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flanged transfer chamber. The flanged flange and the chamber are integrally formed, eliminating the need for circumferential welding between the machined flange and the chamber. The equipment-processed flanged flange reduces manual welding steps, improves production efficiency, and more importantly, further enhances the airtightness of the transfer chamber, eliminating the possibility of deformation due to welding, which could lead to micro-leakage.

[0005] Specifically, this utility model discloses a flanged transfer compartment, comprising:

[0006] The cylindrical body has flanges integrally formed at both ends;

[0007] The hatch assembly includes hatches located on both sides of the cylinder, and also includes a buffer device connected to the hatches.

[0008] The reinforcing plates are fixedly installed on both sides of the cylinder to reinforce the flanges.

[0009] The advantage of adopting the above technical solution is that by setting the flange and integrally forming it with the cylinder, welding is not required, which facilitates installation and ensures the airtightness of the transfer chamber, eliminating the possibility of non-sealing due to welding.

[0010] Furthermore, the hatch assembly also includes a fixing rod for moving the hatch, one end of which is rotatably fixed to the reinforcing plate, and the other end of which is detachably connected to the reinforcing plate.

[0011] The advantage of adopting the above technical solution is that the fixing rod is designed to rotate at one end and be detachable at the other end, which greatly facilitates the opening and closing of the hatch and ensures that the opening degree of the hatch meets the requirements.

[0012] Furthermore, a large cabin shaft is provided in the middle of the fixing rod. The large cabin shaft is rotatably installed with the cabin door. The large cabin shaft is provided with external threads. A nut is installed on the fixing rod. The large cabin shaft passes through the nut. A rotating handle is installed at the other end of the large cabin shaft.

[0013] The advantage of adopting the above technical solution is that by rotating the handle, the position of the hatch can be changed, so that the hatch is pressed against the flange to secure it. Reverse rotation causes the hatch to rise, so that the hatch is separated from the shell and the hatch can be opened easily.

[0014] Furthermore, the reinforcing plate is provided with a protrusion, one end of the buffer device is hinged to the protrusion and the other end is hinged to the fixing rod.

[0015] The advantages of adopting the above technical solution are that the protrusion is used to directly fix the buffer device. In the prior art, a single support rod is generally used for fixing, which not only occupies a lot of space but is also prone to shaking and is inconvenient to install. This application sets an integrally formed protrusion on the fixing plate, which eliminates the need for a separate support rod, occupies less space, is more compact overall, and has a more attractive appearance. The reduction of the number of uprights reduces material and manufacturing costs on the one hand, and reduces manufacturing difficulty on the other hand, improving the fitting accuracy between the buffer device and the large compartment, making it smoother.

[0016] Furthermore, the buffer device includes a gas spring, one end of which is hinged to the fixed rod, and the other end is hinged and fixed to the protrusion of the reinforcing plate.

[0017] The advantage of adopting the above technical solution is that after the hatch is separated from the flange, the gas spring automatically extends to open the hatch automatically, which facilitates subsequent operations.

[0018] Furthermore, a sealing ring is provided between the hatch and the flange.

[0019] The advantage of adopting the above technical solution is that the sealing ring plays a sealing role, ensuring that there is no air leakage between the hatch and the cylinder, and ensuring the airtightness of the entire transfer chamber.

[0020] Furthermore, the reinforcing plate is provided with symmetrically arranged pads, and a first fixed shaft and a second fixed shaft are respectively provided on the pads. The first fixed shaft passes through the fixed rod, and the fixed rod rotates around the first fixed shaft. The other end of the fixed rod is provided with a clearance groove to avoid the second fixed shaft. When the hatch is closed, the second fixed shaft is located in the clearance groove.

[0021] The advantage of adopting the above technical solution is that by setting the first fixed shaft, one end of the fixed plate can be rotated, while the second fixed shaft plays a fixing role. This arrangement allows the hatch to be opened and fixed, facilitating the transfer of the transfer compartment.

[0022] Furthermore, the cylinder is equipped with a pressure gauge.

[0023] The advantage of adopting the above technical solution is that the pressure gauge is used to detect the pressure inside the transmission chamber, so that the pressure inside the transmission chamber meets the usage requirements.

[0024] Furthermore, the cylinder is provided with a vent.

[0025] The advantage of adopting the above technical solution is that the vent is designed for vacuuming or filling with inert gases such as nitrogen, ensuring different usage needs.

[0026] Furthermore, the plane containing the flange is perpendicular to the axis of the cylinder.

[0027] The advantages of adopting the above technical solution are that, compared with the traditional large compartment, the one-piece molded flanged large compartment reduces the number of welds by 80%, and the natural leakage rate will be lower; compared with the traditional large compartment, it reduces the number of two machined flanges at both ends, effectively reducing material and manufacturing costs. At the same time, due to the welding operation method of the existing technology, the flange may be skewed during welding, which may cause leakage between the entire cylinder and the hatch. The flanged flange of this application can effectively reduce leakage and ensure airtightness. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] like Figure 1-7 As shown, this utility model discloses a flanged transfer compartment, comprising:

[0040] The cylindrical body 1 has integrally formed flanges 2 at both ends;

[0041] The hatch assembly includes hatches 3 disposed on both sides of the cylinder 1, and also includes a buffer device connected to the hatches 3;

[0042] The reinforcing plate 4 is fixedly installed on both sides of the cylinder 1 to provide reinforcement. The reinforcing plate 4 is connected to the flange 2 by spot welding.

[0043] The advantage of adopting the above technical solution is that by setting the flange 2, which is integrally formed with the cylinder 1, welding is not required. This facilitates installation and ensures the airtightness of the transfer chamber, eliminating the possibility of non-sealing due to welding.

[0044] The hatch assembly also includes a fixing rod 5, which is used to move the hatch 3. One end of the fixing rod 5 is rotatably fixed to the reinforcing plate 4, and the other end of the fixing rod 5 is detachably connected to the reinforcing plate 4. The fixing rod 5 can be a square rod. The hatch assembly is located on both sides of the cylinder 1, sealing both sides of the cylinder 1. One end is connected to the glove box, and the other end is used to load the product.

[0045] The advantage of adopting the above technical solution is that the fixing rod 5 is designed to rotate at one end and be detachable at the other end, which greatly facilitates the opening and closing of the hatch 3 and ensures that the opening degree of the hatch 3 meets the requirements.

[0046] Furthermore, a large cabin shaft 51 is provided in the middle of the fixing rod 5. The large cabin shaft 51 is rotatably installed with the cabin door 3. A pressure cover is installed on the cabin door 3. The pressure cover is installed in the middle of the cabin door 3. The large cabin shaft 51 is connected to the pressure cover and can rotate. The large cabin shaft 51 is provided with external threads. A nut is fixedly installed on the fixing rod 5. The large cabin shaft 51 passes through the nut. A rotating handle 6 is installed on the other end of the large cabin shaft 51.

[0047] By rotating the handle 6, the position of the hatch 3 can be changed, so that the hatch is pressed against the flange 2 to secure the hatch 3. Rotating it in the opposite direction will raise the hatch 3, so that the hatch 3 is separated from the cylinder 1 and can be opened.

[0048] Furthermore, the rotating handle 6 is equipped with multiple branch rods 61, each branch rod 61 having a handle. The rotating handle 6 is equipped with a rotating body 62, with the branch rods 61 fixedly connected to the rotating body 62. The rotating body 62 is fixedly connected to the upper end of the large cabin shaft 51. By rotating the rotating handle 6, the rotating body 62 drives the large cabin shaft 51 to rotate. Since the large cabin shaft 51 is provided with external threads, it cooperates with the nut located on the fixed rod 5 to realize the up and down movement of the large cabin shaft 51, further driving the hatch 3 to move, realizing the opening and closing of the hatch 3. At the same time, it can also realize the closing and pressing of the hatch 3 to ensure the airtightness of the entire transfer cabin. The arrangement of multiple branch rods 61 facilitates the rotation operation and effectively improves the operation efficiency.

[0049] Furthermore, the reinforcing plate 4 is provided with a protrusion. One end of the buffer device is hinged to the protrusion and the other end is connected to the fixing rod 5. The buffer device includes a gas spring 7. One end of the gas spring 7 is hinged to the fixing rod 5 and the other end is hinged to the protrusion of the reinforcing plate 4. It is easy to install, does not require the installation of a separate upright, occupies less space, is more compact, and has a more beautiful appearance. The reduction of the upright setting reduces material and manufacturing costs on the one hand, and reduces manufacturing difficulty on the other hand. It improves the matching accuracy between the buffer device and the large compartment, making it smoother. The structure and working principle of the gas spring 7 are existing technologies. After the hatch 3 is separated from the flange 2, the gas spring 7 automatically extends to open the hatch 3 automatically, which facilitates subsequent operations.

[0050] In some implementation schemes, a sealing ring is provided between the hatch 3 and the flange 2. The sealing ring is an O-ring and is fixed on the hatch 3. When the hatch 3 is closed, it contacts the flange 2. The sealing ring plays a sealing role, ensuring that there is no air leakage between the hatch 3 and the cylinder 1, and ensuring the airtightness of the entire transfer chamber.

[0051] In some embodiments, the reinforcing plate 4 is provided with symmetrically arranged pads 41, which are fixedly mounted on the extensions on both sides of the reinforcing plate 4. A first fixing shaft 42 and a second fixing shaft 43 are respectively fixedly installed on the pads 41. The first fixing shaft 42 passes through the fixing rod 5, which rotates around the first fixing shaft 42. The other end of the fixing rod 5 is provided with a clearance groove 44 to avoid the second fixing shaft 43. When the hatch 3 is closed, the second fixing shaft 43 is located in the clearance groove 44. By setting the first fixing shaft 42, one end of the fixing rod can rotate, while the second fixing shaft 43 plays a fixing role. This arrangement allows the hatch 3 to be opened and fixed, facilitating the use of the transfer compartment. In addition, the reinforcing plate 4 can be two semi-circular rings, which facilitates spot welding and fixing with the flange.

[0052] In some implementations, the cylinder 1 is equipped with a pressure gauge 8.

[0053] The advantage of adopting the above technical solution is that the pressure gauge 8 is set to detect the pressure inside the transmission chamber, so that the pressure inside the transmission chamber meets the usage requirements.

[0054] Furthermore, the cylinder 1 is provided with a vent 81. The vent 81 is provided for vacuuming or filling with nitrogen to meet different usage needs.

[0055] In some implementations, the plane of the flange 2 is perpendicular to the axis of the cylinder 1. After the sheet metal is rolled into a circle by the equipment and the butt joint is welded, the cylinder 1 is turned outward on the flange machine to form the flange 2 which is perpendicular to the axis of the original cylinder 1.

[0056] The flange 2 makes good contact with the hatch 3, ensuring the sealing performance of the cylinder 1.

[0057] In use, one end of the transfer chamber extends into the glove box. When it is necessary to transfer products into the glove box, open the other side door 3 to transfer the products into the glove box. Then, vacuum the inside and add inert gas, and then open the glove box door 3 to transfer the products into the glove box. This effectively ensures that the water-free and oxygen-free environment is not disrupted when transferring items into the glove box.

[0058] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
