Description

Technical Field

[0001] The utility model relates to a display cabinet, in particular to a cultural relic display cabinet. Background Art

[0002] A display cabinet is a container used to display items. It can be used to display cultural relics, and in order to prevent the cultural relics from oxidizing, special protective gases are usually added to the display cabinet.

[0003] For example, in a prior art cultural relic display cabinet (publication number: CN212368690U0), the cultural relic is isolated from the atmosphere by a closed cavity formed by a cover and a cabinet body, and then the air in the closed cavity is extracted through an exhaust pipe, and an inert gas is filled into the closed cavity through an inflation pipe to prevent oxidation of the cultural relic;

[0004] However, the prior art is not suitable for inert gases heavier than air: the reason is that inert gases heavier than air enter the hood through the air inlet pipe and gather at the bottom of the hood, but the outlet end of the inflation pipe in the prior art is at the same horizontal height as the inlet end of the outlet pipe, so that when the exhaust equipment is used to extract the air in the hood, the inflation pipe fills the hood with inert gas, causing the inert gas gathered at the bottom of the hood to be extracted, while the original air in the hood cannot be quickly extracted; therefore, the applicant proposes a cultural relic display cabinet that can be quickly and effectively filled with inert gas. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a cultural relic display cabinet is proposed. In order to achieve the above purpose, the utility model adopts the following technology: a cultural relic display cabinet, including a base, a glass cover and an air outlet pipe, a first motor is embedded and fixedly connected at one of the corner positions on the upper surface of the base, a driving shaft of the first motor is fixedly connected to a screw rod placed along the height direction of the glass cover, a lifting block is threadedly connected to the surface of the screw rod, one end of the air outlet pipe is fixed on the lifting block, and linear guide rods parallel to the screw rods are fixedly connected to the upper surface of the base at both sides of the screw rod, and the linear guide rods penetrate the lifting block.

[0006] As a further description of the above technical solution: a cavity is opened on the base at the first motor, the inner bottom surface of the cavity is rotatably connected to a tube collecting disk, the air outlet pipe is wound around the tube collecting disk, and the air outlet end of the air outlet pipe is fixed on the tube collecting disk, and the bottom of the cavity is embedded and fixedly connected with a second motor for driving the tube collecting disk to rotate.

[0007] As a further description of the above technical solution: an air outlet is opened on the cavity wall, an air pump connected to the air outlet is fixedly connected to the base, the base has an air inlet pipe running through the side and top surface, and the air outlet end of the air inlet pipe is at the inner corner of the glass cover.

[0008] As a further description of the above technical solution: a spring is fixedly connected to the inner wall of the air outlet pipe.

[0009] As a further description of the above technical solution: an inert gas monitoring and alarm device is fixedly connected to the outer side of the lifting block.

[0010] As a further description of the above technical solution: a lifting platform for displaying cultural relics is embedded and fixedly connected in the center of the base.

[0011] As a further description of the above technical solution: the screw rod is rotatably connected to the inner top surface of the glass cover, and the linear guide rod is in contact with the inner top surface of the glass cover.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a lifting device of the air outlet pipe, when the inert gas is filled into the glass cover, the height of the air inlet can be adjusted according to the density of different inert gases. When the inert gas filled from the air inlet pipe is heavier than the air, the first motor drives the screw to rotate, thereby driving the lifting block to vertically rise under the restriction of the linear guide rod, so that the air outlet pipe fixedly connected to the lifting block rises to the top of the glass cover, and the inert gas enters the glass cover from the air inlet pipe and gradually accumulates upward at the bottom of the glass cover. The air is squeezed at the top, so that the original air in the glass cover is discharged from the air outlet pipe. It can be suitable for inert gases heavier than air to be used as protective gases.

[0014] 2. In the utility model, by setting an inert gas monitoring alarm near the air inlet end of the air outlet pipe, when the alarm is sounded, it means that the inert gas fills the glass cover, so the air extraction and inflation are stopped, the air inlet is sealed, and the air pump is stopped, which can effectively reduce the waste of inert gas.

[0015] 3. In the utility model, by providing an air pipe recovery device, the redundant air pipes can be stored when the air pipes follow the lifting block to descend, thus saving space.

[0016] 4. In the utility model, the spring arranged on the inner wall of the air outlet pipe can effectively prevent the air outlet pipe from being entangled in the tube collecting disk, and the squeezing between the air outlet pipes causes the air outlet pipe to be flattened and then blocked, which is conducive to the smooth extraction of air from the air outlet pipe.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-5 As shown, a cultural relic display cabinet includes a base 1, a glass cover 2 and an air outlet pipe 3. A first motor 4 is embedded and fixedly connected at one of the corners on the upper surface of the base 1. The driving shaft of the first motor 4 is fixedly connected to a screw rod 5 placed along the height direction of the glass cover 2. A lifting block 6 is threadedly connected to the surface of the screw rod 5. One end of the air outlet pipe 3 is fixed to the lifting block 6. Linear guide rods 7 parallel to the screw rod 5 are fixedly connected to the upper surface of the base 1 at both sides of the screw rod 5. The linear guide rod 7 passes through the lifting block 6.

[0026] In this solution, the first motor 4 drives the screw 5 to rotate, and the lifting block 6 can be vertically lifted and lowered with the rotation of the screw 5 under the restriction of the linear guide rod 7, so that the air inlet end of the air outlet pipe 3 fixed on the lifting block 6 can be adjusted up and down;

[0027] When the inert gas filled from the air inlet pipe 16 is heavier than air, the first motor 4 drives the screw 5 to rotate, thereby driving the lifting block 6 to rise vertically under the restriction of the linear guide rod 7, so that the air outlet pipe 3 fixedly connected to the lifting block 6 rises to the top of the glass cover 2, and the inert gas enters the glass cover 2 from the air inlet pipe 16, and gradually accumulates upward at the bottom of the glass cover 2, and the air is squeezed at the top, so that the original air in the glass cover 2 is discharged from the air outlet pipe 3;

[0028] When the inert gas filled from the air inlet pipe 16 is lighter than air, the first motor 4 drives the screw 5 to rotate, thereby driving the lifting block 6 to vertically descend under the restriction of the linear guide rod 7, so that the air outlet pipe 3 fixedly connected to the lifting block 6 descends to the bottom of the glass cover 2, and the inert gas enters the glass cover 2 from the air inlet pipe 16 and gradually accumulates upward at the bottom of the glass cover 2. The air is squeezed at the bottom, so that the original air in the glass cover 2 is discharged from the air outlet pipe 3.

[0029] like Figure 3 As shown, a cavity 8 is opened on the base 1 at the first motor 4, and the inner bottom surface of the cavity 8 is rotatably connected to the tube collecting disk 9, the air outlet pipe 3 is wound around the tube collecting disk 9, and the air outlet end of the air outlet pipe 3 is fixed on the tube collecting disk 9 to prevent the air outlet end from being wound into the air outlet pipe 3, and a second motor 10 for driving the tube collecting disk 9 to rotate is embedded and fixedly connected at the bottom of the cavity 8.

[0030] In this solution, the second motor 10 drives the tube collecting disk 9 to rotate, and the air outlet pipe 3 is wound around the tube collecting disk 9. As the tube collecting disk 9 rotates, it is rolled into the tube collecting disk 9, so that when the lifting block 6 descends, the excess air outlet pipe 3 can be effectively stored, reducing the space occupied.

[0031] like Figure 2 As shown, an air outlet 11 is opened on the wall of the cavity 8, and an air pump 12 connected to the air outlet 11 is fixedly connected to the side of the base 1. The base 1 has an air inlet pipe 16 that runs through the side and top surface, and the air outlet end of the air inlet pipe 16 is at the inner corner of the glass cover 2.

[0032] In this solution, when the vacuum pump 12 is turned on, the air in the glass cover 2 can be quickly extracted, and when the vacuum pump 12 is turned off, air is prevented from entering the glass cover 2 from the air outlet 11.

[0033] Inert gas is introduced into the glass cover 2 through the air inlet pipe 16 .

[0034] The vacuum pump 12 is preferably a 2XZ type vacuum pump.

[0035] like Figure 5 As shown, a spring 13 is fixedly connected to the inner wall of the air outlet pipe 3 .

[0036] This solution can effectively prevent the air outlet pipe 3 from being flattened and then blocked due to winding and squeezing when the air outlet pipe 3 is rolled up by the tube-retracting disk 9, so it is helpful to maintain smooth air extraction.

[0037] like Figure 4 As shown, an inert gas monitoring alarm 14 is fixedly connected to the outer side of the lifting block 6 .

[0038] In this solution, the lifting block 6 is fixedly connected to the gas outlet pipe 3, and the inert gas monitoring alarm 14 is close to the gas inlet end of the gas outlet pipe 3. When the inert gas is just filled, the inert gas monitoring alarm 14 alarms and reminds, so that it can be known in time that the inert gas has filled the glass cover 2.

[0039] like Figure 2 As shown, a lifting platform 15 for displaying cultural relics is embedded and fixedly connected in the center of the base 1.

[0040] This solution can adapt to the display of cultural relics at different heights, which is conducive to improving the display effect of cultural relics.

[0041] The lifting platform 15 in this solution is a scissor lift.

[0042] like Figure 2 As shown, the screw rod 5 is rotatably connected to the inner top surface of the glass cover 2 , and the linear guide rod 7 is in contact with the inner top surface of the glass cover 2 .

[0043] This solution can enable the lifting block 6 to carry the air outlet pipe 3 to the top of the glass cover 2, and support the glass cover 2 through the screw rod 5 and the linear guide rod 7.

[0044] Working principle: When the inert gas filled in is heavier than air, the inert gas filled in from the air inlet pipe 16 will gradually accumulate upward from the bottom of the glass cover 2, and the air will be squeezed at the top. At this time, the first motor 4 drives the screw 5 to rotate, thereby driving the lifting block 6 to rise vertically under the restriction of the linear guide rod 7, so that the air outlet pipe 3 fixedly connected to the lifting block 6 rises accordingly. At the same time, the second motor 10 drives the tube collecting disk 9 to rotate, and the air outlet pipe 3 is released. The air inlet end of the air outlet pipe 3 is located at the top of the glass cover 2. The vacuum pump 12 extracts the air at the top of the glass cover 2 through the air outlet pipe 3. When the inert gas monitoring alarm 14 located near the air inlet end of the air outlet pipe 3 gives an alarm, it means that the inert gas fills the glass cover 2, so the vacuum and inflation are stopped, the air inlet is sealed, and the vacuum pump 12 is stopped.

[0045] When the inert gas filled is lighter than air, the inert gas filled from the air inlet pipe 16 will gradually accumulate downward from the top of the glass cover 2, and the air will be squeezed at the bottom. At this time, the first motor 4 drives the screw 5 to rotate, thereby driving the lifting block 6 to vertically descend under the restriction of the linear guide rod 7, so that the air outlet pipe 3 fixedly connected to the lifting block 6 descends accordingly, and the air inlet end of the air outlet pipe 3 is located at the bottom end of the glass cover 2, and the air pump 12 extracts the air at the bottom of the glass cover 2 through the air outlet pipe 3. At the same time, the second motor 10 drives the tube receiving disk 9 to rotate, and the air outlet pipe 3 is wound around the tube receiving disk 9. As the tube receiving disk 9 rotates, it is rolled into the tube receiving disk 9, so that the redundant air outlet pipe 3 can be effectively stored when the lifting block 6 descends. When the inert gas monitoring alarm 14 located near the air inlet end of the air outlet pipe 3 gives an alarm, it means that the inert gas fills the glass cover 2, so the air extraction and inflation are stopped, the air inlet is sealed, and the air pump 12 is stopped.

[0046] The first motor 4 and the second motor 10 of this solution are preferably ET-SGM10 micro motors.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
