[0041] Example 1

[0042] A tobacco leaf sample display device, such as Figure 1 As shown, it includes a display component 100, which includes a transparent cabinet, a base 101 is arranged at the bottom of the transparent cabinet, a support component 200 is arranged inside the transparent cabinet, and the support component 200 includes a support rod 201 connected to the base 101, and a plurality of tobacco leaf supports 202 of changeable shape are arranged on the support rod 201.

[0043] The transparent cabinet in this embodiment is cylindrical, and is composed of a first curved plate 102 and a second curved plate 103. The materials of the first curved plate 102 and the second curved plate 103 in this embodiment are both transparent glass. The first curved plate 102 is provided with a hollow interlayer, and the second curved plate 103 is slidably connected in the hollow interlayer; when the second curved plate 103 slides out of the hollow interlayer of the first curved plate 102, the first curved plate 102 can form a cylindrical shape with the second curved plate 103, and form a relatively sealed space with the top plate 104 and the base 101, that is, the transparent cabinet is in a closed state, which is used to store and display tobacco leaves; when the second curved plate 103 slides into the hollow interlayer of the first curved plate 102, the transparent cabinet is opened, and tobacco leaves can be placed or replaced.

[0044] In this embodiment, the top of the first curved plate 102 is fixedly connected to the top plate 104, and the bottom of the first curved plate 102 is fixedly connected to the base 101. Sealing strips are respectively provided at both ends of the first curved plate 102 and the second curved plate 103. When the transparent cabinet is closed, the sealing performance is increased and the preservation time of the tobacco leaves is improved. In this embodiment, the base 101 and the top plate 104 are both provided with slide grooves, and the top and bottom of the second curved plate 103 slide along the upper and lower slide grooves respectively.

[0045] like Figure 2As shown, the tobacco leaf support 202 includes a fixed shell 202a fixed on the support rod 201, and the fixed shell 202a is rotatably connected to a hinged rod 202b inside, and the hinged rod 202b is magnetically clamped with a magnetic connecting block 202c at one end away from the fixed shell 202a, and a main deformable rod 202d is fixed on the magnetic connection block 202c, and a plurality of auxiliary deformable rods 202e are arranged on the main deformable rod 202d. In this embodiment, the main deformable rod 202d and the auxiliary deformable rod 202e are both made of shape memory alloy, and can also be made of metal strips or metal wires that can be bent at will. The staff can manually adjust the shapes of the main deformable rod 202d and the auxiliary deformable rod 202e to adapt to different tobacco leaves and improve the display effect. The secondary deformation rod 202e is provided with a tobacco leaf clamping member 202f, and the tobacco leaf clamping member 202f can clamp tobacco leaves with a clamp, effectively preventing the tobacco leaves from falling, and the fixing method is simple, and the tobacco leaves are easy to replace.

[0046] The main deformation rods 202d of the multiple tobacco leaf supports 202 are distributed in an interlaced manner along the length direction of the support rod 201 to support the main vein position of the tobacco leaves; the multiple auxiliary deformation rods 202e are distributed in an interlaced manner along the length direction of the main deformation rod 202d to support the leaves on both sides of the main vein of the tobacco leaves; the set support rod 201 can simulate the main stem of the tobacco plant, and placing tobacco leaves on the main deformation rod 202d and the auxiliary deformation rod 202e can simulate the growth posture of tobacco leaves on the tobacco plant, and the display effect is better.

[0047] The hinged rod 202b is slotted at one end away from the support rod 201, and a magnetic block is fixedly installed in the slot. The magnetic connection block 202c contains a magnetic block inside, so it can automatically be magnetically attracted and fixed to the hinged rod 202b to improve the stability of the connection. The main deformation rod 202d is set to be detachable through the magnetic connection block 202c, which is convenient for the staff to adjust the number of tobacco leaves displayed as needed, and the appearance is higher. In addition, the hinged rod 202b is rotatably connected to the fixed shell 202a, so the staff can push the hinged rod 202b to adjust the angle of the tobacco leaves, further improving the tobacco leaf display effect. A rubber damping plate is installed between the hinged rod 202b and the fixed shell 202a to increase the rotational friction, so that the adjusted tobacco leaves can still maintain good stability.

[0048] The support rod 201 is located at the center of the transparent cabinet. The bottom of the support rod 201 is connected to the base 101. A motor 201a is fixedly installed inside the base 101. The output shaft of the motor 201a is fixedly connected to the bottom of the support rod 201. The support rod 201 is driven to rotate by the motor 201a. The top of the support rod 201 is rotatably connected to the top plate 104. A rotating shaft is installed inside the top plate 104. The rotating shaft is assembled and unassembled from the support rod 201 through a sleeve. The motor 201a and the support rod 201 can rotate and display the fixed tobacco leaves, and the display effect is better.

[0049] A temperature controller and a humidity controller are installed inside the transparent cabinet. The temperature controller and the humidity controller are two devices used to adjust the ambient temperature and humidity. The temperature controller refers to a series of automatic control elements that physically deform inside the switch according to the temperature changes in the working environment, thereby generating a conduction or disconnection action. It is also called a temperature control switch, a temperature protector, a temperature controller, or a thermostat for short. The humidity controller refers to a switch that controls the humidification or dehumidification equipment according to the humidity changes in the working environment to maintain the required humidity level. It is also called a humidity control switch, a humidity protector, a humidity controller, or a humidity controller for short. Therefore, the temperature and humidity of the tobacco storage environment can be adjusted by the above to increase the storage time of the tobacco leaves.

[0050] Four symmetrically distributed rollers are installed at the bottom of the base 101, and a battery is installed inside the base 101 to power the device. The rollers are convenient for the staff to push the base 101 to the designated position, saving time and effort; the battery can provide power for the internal device, so that it does not need to be connected by wires during display, which is more convenient to use.

[0051] The method for using the tobacco leaf sample display device provided by the utility model is as follows: when in use, according to the number of tobacco leaves that need to be displayed, the number and position of the main deformation rods 202d on the support rod 201 are determined, and then the shapes of the main deformation rods 202d and the auxiliary deformation rods 202e are changed, and the tobacco leaves are placed on the main deformation rods 202d and the auxiliary deformation rods 202e, and fixed with the tobacco leaf clamps 202f; the second arc plate 103 is slid to close the transparent cabinet, and the motor 201a is started, and the support rod 201 drives the tobacco leaves to rotate for display.

[0052] The tobacco leaf sample display device provided by the utility model has a compact overall structure, is more portable, can be displayed in three dimensions, can restore the position and growth state of the tobacco leaves on the tobacco plants, has good display and decorative effects, improves the diversity of tobacco leaf displays, and can also be used as an ornament.

[0053] Example 2

[0054] A tobacco sample display device, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: this embodiment is also provided with a positioning component 500 for positioning the second arc plate 103 to prevent non-staff from accidentally opening the transparent cabinet during display.

[0055] like Figure 3 and Figure 4As shown, a positioning ring 101a is fixed on the top of the base 101, and an arc-shaped slide groove 101d is fixed on the top of the positioning ring 101a. The bottom of the first arc plate 102 is fixedly connected to the arc-shaped slide groove 101d, and the arc length and curvature of the arc-shaped slide groove 101d are consistent with the arc length and curvature of the first arc plate 102. A rotating ring 101b concentric with the positioning ring 101a is slidably connected to the positioning ring 101a, and the rotating ring 101b is located in the arc-shaped slide groove 101d and slides along the arc-shaped slide groove 101d. The bottom of the second arc plate 103 is fixedly connected to the rotating ring 101b, and an opening 101e is provided on the top of the arc-shaped slide groove 101d to facilitate the installation of the second arc plate 103. The bottoms of the two side walls on both sides of the hollow interlayer of the first arc plate 102 are fixed on both sides of the opening 101e. When the transparent cabinet is closed, the rotating ring 101b slides along the positioning ring 101a, and the second arc plate 103 slides out of the arc slot 101d to form a sealed space with the first arc plate 102; when the transparent cabinet is opened, the rotating ring 101b rotates, and the second arc plate 103 slides into the arc slot 101d.

[0056] like Figure 5 and Figure 6 As shown, the positioning assembly 500 includes a telescopic member 502 and a valve core 503. The bottom of the rotating ring 101b is provided with a mounting groove 101c with an opening facing downward, the telescopic member 502 is located in the mounting groove 101c, and the valve core 503 is located on the side wall of the mounting groove 101c and is connected to the inside of the mounting groove 101c. The telescopic member 502 includes a telescopic cylinder 502a fixed to the top wall of the mounting groove 101c, a telescopic rod 502b is slidably connected inside the telescopic cylinder 502a, an elastic airbag 502c is installed between the telescopic rod 502b and the telescopic cylinder 502a, the top and bottom of the elastic airbag 502c are respectively fixedly connected to the top of the telescopic rod 502b and the inner top wall of the telescopic cylinder 502a, and a positioning groove 501 is provided on the positioning ring 101a to be clamped with the telescopic rod 502b, and the positioning groove 501 is arranged at one end close to the arc-shaped slide groove 101d.

[0057] The side wall of the installation groove 101c is connected to the negative pressure extraction component 300 through the pipeline component 400. The gas in the installation groove 101c is extracted through the negative pressure extraction component 300, and the air pressure inside the installation groove 101c is reduced. The internal pressure of the elastic airbag 502c is greater than the external pressure, and it will deform and expand, pushing the telescopic rod 502b to move downward until it is inserted into the positioning groove 501, and the second curved plate 103 is positioned; when it is necessary to open the transparent cabinet, the staff squeezes the valve core 503 to allow the outside gas to flow into the installation groove 101c, and the elastic airbag 502c shrinks under the action of pressure, driving the telescopic rod 502b to slide upward and separate from the positioning groove 501, and the second curved plate 103 can slide, and the transparent cabinet can be opened.

[0058] Example 3

[0059] A tobacco leaf sample display device, the technical solution in this embodiment is basically the same as that in embodiment 2, except that: the negative pressure extraction component 300 in this embodiment is located inside the base 101, including a drive component 302 and a piston component 301.

[0060] like Figure 7 and Figure 8 As shown, the piston assembly 301 includes a piston cylinder 301a fixed inside the base 101, and a piston 301b is slidably connected inside the piston cylinder 301a. A connecting rod 301c is fixed to one end of the piston 301b, and the end of the connecting rod 301c away from the piston 301b movably passes through the piston cylinder 301a; the end of the connecting rod 301c away from the piston 301b is connected to the driving assembly 302.

[0061] The driving assembly 302 includes a rotating disk 302a fixedly arranged on the support rod 201, an eccentric sliding groove 302b is provided on the top of the rotating disk 302a, a slider 301d is provided in the eccentric sliding groove 302b, and a connecting rod 301c is fixedly connected to the slider 301d at one end away from the piston 301b. The rotating disk 302a is fixed on the support rod 201, so that it rotates synchronously with the support rod 201. When the rotating disk 302a rotates, the eccentric sliding groove 302b is synchronously driven to rotate. Therefore, the eccentric sliding groove 302b drives the connecting rod 301c to move reciprocatingly through the slider 301d, and the connecting rod 301c drives the piston 301b to slide reciprocatingly inside the piston cylinder 301a to realize the extraction and discharge of gas.

[0062] The pipeline assembly 400 includes an air inlet pipe 401, an air outlet pipe 402 and a pressure relief valve 403. The air inlet pipe 401 connects the mounting groove 101c with the piston cylinder 301a, and the air outlet pipe 402 and the pressure relief valve 403 are both connected with the piston cylinder 301a. Air flow control components 402a are installed inside the air inlet pipe 401 and the air outlet pipe 402. The air inlet of the air inlet pipe 401 is fixed on the positioning ring 101a and is located on one side of the positioning groove 501. When the mounting groove 101c moves to the positioning groove 501, the gas in the mounting groove 101c is extracted through the air inlet.

[0063] like Figure 8 As shown, when the piston 301b moves to the left, the gas in the air inlet pipe 401 is extracted, and when it moves to the right, the extracted gas is discharged from the air outlet pipe 402. The air flow control member 402a installed inside the air inlet pipe 401 and the air outlet pipe 402 is an elastic diaphragm or a gas one-way valve, so the gas flow direction can be controlled, thereby realizing the control of the positioning component 500. The elastic diaphragm is a sheet-shaped elastic element fixed along the outer edge, and the thickness is generally 0.05-0.3mm. When the elastic diaphragm is affected by the gas pressure, it will be displaced, thereby opening or closing to realize the flow of gas.

[0064] When the gas inside the installation groove 101c is completely extracted, the negative pressure generated when the piston 301b moves will become larger and the pressure relief valve 403 will be opened to inhale the gas to ensure the normal operation of the parts, and silencer cotton is installed on the outside of the pressure relief valve 403 to absorb noise.

[0065] The air intake pipe 401 is also provided with an airflow sound generating device, which includes a sound generating tube 401a, which is connected to the air intake pipe 401 and has a sound generating ball 401b placed inside. The sound generating tube 401a used in this embodiment can be any airflow sound generating tube in the prior art.

[0066] When the second arc plate 103 is not closed properly, there will be a gap. Therefore, at this time, the air inlet pipe 401 will continue to extract gas from the installation groove 101c. At this time, the amount of gas extracted is relatively large. Therefore, when the gas flows into the sound tube 401a, the gas vibrates the sound ball 401b. In this way, the sound ball 401b continues to vibrate and emits a prompt sound, which serves as a warning to the staff, thereby ensuring the sealing effect when the second glass cover 103 is closed.

[0067] And when the transparent cabinet is in the open state, the bottom of the rotating ring 101b will block and seal the air inlet pipe 401, so the gas cannot enter the air inlet pipe 401 when the piston assembly 301 is working, thereby solving the problem of the staff accidentally issuing a prompt sound when inspecting the support assembly 200.

[0068] The tobacco leaf sample display device provided by the utility model has the following advantages: the staff can place multiple tobacco leaves on the tobacco leaf support respectively to simulate the posture of the tobacco leaves when growing, and the display effect is better. By setting a detachable magnetic connection block, the staff can adjust the number of tobacco leaves displayed according to needs, and the appearance is higher; the overall structure is compact, more portable, and can be displayed in a three-dimensional manner. It can restore the specific position of the tobacco leaves on the tobacco plants, has a good display and decorative effect, and can also be used as a display; and through the coordinated use of the negative pressure extraction component and the positioning component, the second arc plate can be automatically fixed to prevent the second arc plate from not closing in place, resulting in a poor sealing effect.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
