Description

Technical Field

[0001] The utility model relates to the technical field of getter storage, in particular to a protective device for getter transfer. Background Art

[0002] Because getters effectively adsorb certain gas molecules, they can achieve or maintain a vacuum or purify gases under specific circumstances. Due to their unique properties, getters play an important role in a variety of fields, such as improving the vacuum level of vacuum devices, protecting sensitive components, and serving as medical medications for respiratory diseases.

[0003] Because the getter has a good gas adsorption capacity, it is necessary to protect it from moisture, contamination, mechanical damage, etc. during its storage and transfer. That is, try to avoid prolonged contact with the gas, and keep the container stable during the transfer process to avoid violent shaking or collision to reduce physical damage to the getter.

[0004] At present, the getter is mainly stored in a bottle, and the getter is transferred by transferring the bottle. The types of bottles used to store getter are relatively simple. For example, a Chinese patent with patent number CN217348756U discloses a moisture-proof device for storing getter, which includes a storage bottle, a bottle cap on the top of the storage bottle, and a one-way valve installed on the bottle cap. A shell is fixedly provided at the lower right position of the storage bottle inner cavity, a discharge hole is provided at the upper middle position of the shell, a movable rod is provided at the inner cavity of the shell, one right end of the movable rod passes through the storage bottle and extends to the right side of the storage bottle, a through groove is provided at the same longitudinal position of the movable rod at the discharge hole, a fixed plate is fixedly installed at the left end of the movable rod, a sliding rod is fixedly provided at the upper and lower sides of the movable rod in the inner cavity of the shell, the sliding rod passes through the fixed plate, and a spring is sleeved on the outer wall of the sliding rod and at the right side of the fixed plate.

[0005] When using the bottle provided by the above patent to store the getter, although the amount of gas entering the bottle can be reduced, it can be seen from its operation that if you want to remove the getter from the bottle, you need to shake the bottle to make the getter fall into the through groove. However, according to the characteristics of the getter, it is known that during transfer and storage, it is necessary to avoid shaking or collision, otherwise it will cause physical damage to the getter. In addition, some getters may contain flammable, explosive or other dangerous chemical components. Violent shaking or collision may trigger chemical reactions, posing a safety hazard. Therefore, the bottle provided by the above patent is not convenient for storing the getter well. At the same time, when using the bottle provided by the above patent to store the getter, it is inconvenient to transfer because during the transfer process, the getter is very likely to shake or even collide with the bottle.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The following will be further described in conjunction with the accompanying drawings and specific embodiments:

[0028] Embodiment 1

[0029] In order to avoid physical damage to the getter caused by severe shaking or collision during the transfer process, this embodiment provides a new storage tank 2 for storing the getter. Specifically, see the following.

[0030] As Figure 1 、 Figure 4 、 Figure 5 shown, a threaded port 22 is provided at the top of the storage tank 2 and a gas pipeline communicating with a control valve is provided. A sealing cover 3 is threadedly sleeved at the threaded port 22. A sleeve ring groove 31 is provided on the lower end surface of the sealing cover 3. Threads are provided on the side wall of the sleeve ring groove 31. Therefore, the threaded port 22 can be made unobstructed by rotating the sealing cover 3, which provides convenience for storing or taking out the getter. When the sealing cover 3 blocks the threaded port 22, the gas pipeline can be controlled to be unobstructed through the control valve, so as to pump and discharge the gas located in the storage tank 2 under the action of an air pump or other getter devices, and avoid the getter being moist and contaminated due to long-term contact with the gas.

[0031] As Figure 1 、 Figure 2 shown, in order to avoid physical damage to the getter caused by the shaking of the storage tank 2 during the transfer process, a protection component 1 is provided on the outside of the storage tank 2. The protection component 1 includes a connecting plate 11 and two groups of hoops 12. The two groups of hoops 12 are arranged vertically and distributed inside the connecting plate 11. The outer diameter of the hoop 12 is smaller than the inner diameter of the connecting plate 11 and is sleeved on the storage tank 2. The hoop 12 is connected to the end of the connecting plate 11 through an elastic strip 13. The elastic strip 13 is inclined, and multiple elastic strips 13 are evenly distributed along the circumferential direction of the hoop 12. When transferring the storage tank, the staff directly contacts the connecting plate 11, thereby driving the hoop 12 and the storage tank 2 to move. Due to the buffer elastic strip 13, the shaking generated by the connecting plate 11 can be offset, and the damage to the getter caused by shaking can be avoided. The lower end of the connecting plate 11 is lower than the lower end of the storage tank 2. Then, when placing the device in the workplace, since the connecting plate 11 touches the ground earlier than the storage tank 2, the damage to the getter caused by impact can be avoided.

[0032] As Figure 3 shown, in order to stably install the hoop 12 relative to the storage tank 2, two rings of annular grooves 21 are provided on the outer side surface of the storage tank 2. The two rings of annular grooves 21 are distributed at the upper and lower ends of the storage tank 2. The inner edges of the two groups of hoops 12 respectively extend into the two rings of annular grooves 21, increasing the difficulty of the hoop 12 moving relative to the storage tank 2.

[0033] Embodiment 2

[0034] As shown Figures 5 - 7 In the embodiment 1, in order to discharge the gas in the storage tank 2 more conveniently and avoid affecting the use of the getter due to the lack or damage of the air extraction equipment, a counterbore 32 is provided through the upper side of the sealing cover 3. The lower end surface of the counterbore 32 is flush with the lower end surface of the sealing cover 3. The sleeve ring groove 31 is located outside the counterbore 32. A bottom column 33 is provided at the bottom of the counterbore 32, and an air extraction cylinder 4 is inserted at the upper end. The lower end surface of the air extraction cylinder 4 contacts the upper end surface of the bottom column 33 and has the same outer diameter. An annular convex plate 45 is provided inside the air extraction cylinder 4, and an outer ring plate 46 is provided outside. The outer ring plate 46 is installed at the top of the counterbore 32 through bolts. A tapered hole 34 is provided on the upper end surface of the bottom column 33. The tapered hole 34 communicates with the storage tank 2 and also with the air extraction cylinder 4. Therefore, the gas in the storage tank 2 can be discharged along the air extraction cylinder 4. In order to prevent the outside air from entering the storage tank 2, a sealing plug cone 48 is provided at the tapered hole 34. A spring 47 is provided above the sealing plug cone 48. The spring 47 is in a compressed state and its top contacts the annular convex plate 45. Therefore, under the action of the spring 47, the sealing plug cone 48 fits the tapered hole 34 and blocks the tapered hole 34 to prevent the outside air from entering the storage tank 2.

[0035] Based on the above structure, in order to extract the gas in the storage tank 2, a piston rod 41 is inserted into the air extraction cylinder 4. By pulling the piston rod 41, the gas in the air extraction cylinder 4 can be extracted, thereby forcing the sealing plug cone 48 to move upward and discharging the gas in the storage tank 2.

[0036] In order to facilitate the gas discharge, the maximum diameter of the sealing plug cone 48 is smaller than the inner diameter of the air extraction cylinder 4, and a limiting plate 49 is fixedly provided at the edge. A limiting groove 44 is provided at the lower end of the inner side wall of the air extraction cylinder 4. The limiting plate 49 extends into the limiting groove 44, so that the sealing plug cone 48 is stably and movably arranged in the air extraction cylinder 4.

[0037] In order to extract the gas in the storage tank 2 multiple times, a sealing ring plate 42 is sleeved outside the air extraction cylinder 4, and a ventilation hole 43 is provided at the bottom of the side wall. The sealing ring plate 42 can block the ventilation hole 43. When the piston rod 41 is inserted into the air extraction cylinder 4 again, due to the blockage of the sealing plug cone 48, there is pressure in the air extraction cylinder 4, which is inconvenient for the piston rod 41 to extend in. Therefore, the sealing ring plate 42 can be pulled up, and the outside air can enter the air extraction cylinder 4. At this time, the sealing plug cone 48 extends to the side of the annular convex plate 45 in the air extraction cylinder 4. Before extracting the gas in the storage tank 2, the sealing ring plate 42 needs to block the ventilation hole 43. After extracting the gas in the storage tank 2, if you want to use the getter, the smoothness of the gas transmission pipe can be adjusted by the cylinder control valve to facilitate the entry of the outside air into the storage tank 2 and provide convenience for rotating the sealing cover 3.

[0038] As shown Figure 8As shown, in order to reduce the strength required for the staff to pull the piston rod 41, threads may be provided on the piston rod 41 and penetrate through the internally threaded tube. At the same time, the internally threaded tube is connected to the end of the air extraction cylinder 4. Therefore, the position of the piston can be changed by rotating the piston rod 41.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
