Description

Technical Field

[0001] This utility model relates to the field of adjustable base technology, specifically an adjustable base for an airtight box. Background Technology

[0002] Airtight boxes are used in the field of cultural relic protection to slow down the aging and damage of cultural relics. An adjustable base for an airtight box is a structural component at the bottom of the airtight box. It can adjust the overall height of the airtight box. For example, in different installation environments, if the ground is uneven, the base can be adjusted to keep the box level and ensure that the equipment inside the box operates normally.

[0003] In the prior art, the base of the airtight box is usually set at the bottom of the sealed glass layer. The support column at the bottom contacts the ground to support the airtight box. However, in actual use, since the airtight box is usually heavy, it needs to be moved when adjusting its position. The moving method is not only time-consuming and laborious, but also easy to cause damage to the glass layer. Therefore, it is necessary to improve the airtight box by developing an adjustable base to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable base for an airtight box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable base for an airtight box includes a base one, a base two fixedly mounted on the top of the base one, an airtight box body fixedly mounted on the top of the base two, a partition fixedly mounted inside the base two, a lifting and moving mechanism provided at the bottom of the partition, and an adjustment support mechanism provided inside the base one.

[0007] Preferably, the lifting and moving mechanism includes a motor, which is fixedly installed at the bottom of the partition. A transmission gear is fixedly installed at the bottom of the motor's drive shaft. A hollow transmission roller is rotatably installed on the inner side of the bottom of the second base. A transmission belt is installed on the outer side of the hollow transmission roller. A toothed ring is fixedly installed on the top of the hollow transmission roller on the front side. A hollow transmission roller is fixedly installed on the top of the hollow transmission roller on the outer side. A transmission belt is installed on the outer side of the hollow transmission roller. A threaded rod is installed internally on the hollow transmission roller. A caster is fixedly installed at the bottom of the threaded rod. A limit strip is slidably installed inside the threaded rod to facilitate the lowering of the caster by the lifting and moving mechanism to assist in the movement and adjustment of the airtight box body.

[0008] Preferably, four limiting strips are provided, and the tops of the four limiting strips are fixedly installed to the bottom of the partition plate, so that the threaded rod can descend stably.

[0009] Preferably, the transmission gear meshes with the gear ring, and the threaded rod is disposed inside the gear ring to facilitate normal synchronous descent of the universal wheel.

[0010] Preferably, the base has a hole inside, and the threaded rod is disposed inside the hole inside the base, so as to facilitate the normal movement of the threaded rod.

[0011] Preferably, the adjusting support mechanism includes a rotating limiting seat, which is fixedly installed on the top inner side of the base one. A rotating bevel gear is rotatably installed inside the rotating limiting seat, and a threaded rod two is fixedly installed at the bottom of the rotating bevel gear. A support limiting post is installed on the external thread of the threaded rod two. A rotating screw shaft is rotatably installed inside the base one, and a fixed bevel gear is fixedly installed on the inner side of the rotating screw shaft, so as to facilitate the adjustment of the support height of the airtight box body by adjusting the supporting mechanism.

[0012] Preferably, the rotating bevel gear meshes with the fixed bevel gear, and a groove is provided at the corresponding position of the base and the support limiting post. The support limiting post is slidably installed inside the groove provided inside the base, which facilitates normal adjustment of the position of the support limiting post.

[0013] Compared with the prior art, this utility model provides an adjustable base for an airtight box, which has the following advantages:

[0014] 1. The adjustable base of this airtight box, through the set lifting and moving mechanism, during use, utilizes the transmission of the set transmission gears and gear rings, as well as the transmission of hollow transmission roller one and transmission belt one, and hollow transmission roller two and transmission belt two, to enable the four threaded rods one to descend synchronously under the limit of the limit strip, thereby making the casters contact the ground. The casters assist in the movement of the airtight box body, avoiding the need to spend more time and effort during transportation, and can also effectively prevent the glass layer from being bumped and damaged when adjusting the position.

[0015] 2. The airtight box has an adjustable base. Through the set adjustment support mechanism, during use, by rotating the rotating shaft, the fixed bevel gear drives the rotating bevel gear to rotate, which changes the position of the support limit column, thereby adjusting the support height. The method of adjusting the support limit column alone can be adjusted according to environmental conditions, realizing the function of adjusting the support height of the airtight box body through the base.

[0027] Furthermore, four limit bars 210 are provided, and the tops of the four limit bars 210 are fixedly installed with the bottom of the partition plate 6, so that the threaded rod 28 can descend stably.

[0028] Furthermore, the transmission gear 22 meshes with the gear ring 25, and the threaded rod 28 is located inside the gear ring 25 to facilitate the normal synchronous descent of the universal wheel 29.

[0029] Furthermore, the base 1 has a hole inside, and the threaded rod 28 is located inside the hole inside the base 1, so that the threaded rod 28 can move normally. Example 2

[0030] Please see Figure 5Furthermore, in conjunction with Embodiment 1, the adjusting support mechanism 3 includes a rotation limiting seat 31, which is fixedly installed on the top inner side of the base 1. A rotating bevel gear 32 is rotatably installed inside the rotating limiting seat 31. A threaded rod 33 is fixedly installed at the bottom of the rotating bevel gear 32. A support limiting post 34 is installed on the external thread of the threaded rod 33. A rotating shaft 35 is rotatably installed inside the base 1. A fixed bevel gear 36 is fixedly installed on the inner side of the rotating shaft 35, which facilitates adjusting the support height of the airtight box body 5 through the adjusting support mechanism 3.

[0031] Furthermore, the rotating bevel gear 32 meshes with the fixed bevel gear 36, and the corresponding positions of the base 1 and the support limiting post 34 are provided with grooves, and the support limiting post 34 is slidably installed inside the grooves provided inside the base 1, so as to facilitate normal adjustment of the position of the support limiting post 34.

[0032] Working principle: In actual operation, when this device is in use, when the airtight box body 5 is placed, the rotating shaft 35 is rotated, which causes the fixed bevel gear 36 to drive the rotating bevel gear 32 to rotate. At this time, the rotating bevel gear 32 drives the threaded rod 33 to rotate, which allows the support limit column 34 to descend and change the support height of the airtight box body 5. When it is necessary to adjust the position of the airtight box body 5, the drive motor 21 is driven, which causes the transmission gear 22 to rotate. The transmission gear 22 drives the gear ring 25 to rotate. At this time, through the transmission of the transmission belt 24, the hollow transmission roller 26 and the transmission belt 27, the four hollow transmission rollers 23 start to rotate synchronously in the same direction, which drives the threaded rod 28 to descend under the restriction of the limit bar 210. At this time, the caster wheel 29 descends and contacts the ground. At this time, the airtight box body 5 is pushed, which makes the airtight box body 5 move.
