Description

Technical Field

[0001] The invention relates to the technical field of display bases, and in particular to a ceramic handicraft protection and display base. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Pottery, primarily made from highly viscous and plastic clay, is opaque, has fine pores, and absorbs little water, resulting in a murky sound when struck. Porcelain, on the other hand, is made from clay, feldspar, and quartz. It is translucent, non-absorbent, corrosion-resistant, and has a hard, dense body with a crisp sound when tapped. Traditional ceramic arts and crafts are of high quality, beautiful form, and possess a high degree of artistic value.

[0003] Since ceramic handicrafts are easily bumped and broken, protective devices are needed to protect them during their display. A common method is to place the ceramic handicrafts on a base and then put a transparent cover on the outside to protect the ceramic handicrafts and ensure that their viewing is not affected.

[0004] Currently, ceramic crafts are usually placed directly on a base or fixed by a clamping device. If the direct placement method is adopted, the ceramic crafts are prone to bumps due to collisions or other factors. If the ceramic crafts are clamped and fixed with a clamp, although the stability of the ceramic craft display process can be guaranteed to a certain extent, no matter where the clamp is clamped on the ceramic craft, it will cause a certain degree of obstruction to the main body of the ceramic craft, resulting in incomplete display of the ceramic craft and affecting the appreciation effect. Therefore, the present application proposes a ceramic craft protection display base to solve the above problems. Summary of the Invention

[0005] The present invention provides a ceramic handicraft protection and display base to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A ceramic handicraft protection and display base includes a display stand, the bottom of the display stand is fixedly connected to a base via a plurality of support rods, the top of the base is fixedly connected to a protective cover, the top of the protective cover is movably connected to a cover plate, and the protective cover and the cover plate are both made of transparent material.

[0008] A fixing groove is provided in the middle of the display stand, and a suction cup is movably connected inside the fixing groove. The upper surface of the suction cup is higher than the upper surface of the display stand. The suction cup is made of soft material. The bottom end of the suction cup is fixedly connected to the lower surface of the display stand through multiple fixing rods, and a gas processing mechanism is provided at the bottom of the suction cup.

[0009] A further improvement of the technical solution of the present invention is that the gas processing mechanism includes an air pipe fixedly connected to the bottom of the suction cup, one end of the air pipe is fixedly connected to a gas storage tank, the suction cup, the air pipe, and the interior of the gas storage tank are connected through and through, and a piston plate is movably connected to the inner wall of the gas storage tank, and the piston plate can slide up and down along the inner wall of the gas storage tank.

[0010] A further improvement of the technical solution of the present invention is that a lifting rod is fixedly connected to the bottom of the inner cavity of the gas storage tank, and the output end of the lifting rod is fixedly connected to the piston plate. In the initial stage, the piston plate is at the top and the lifting rod is in an extended state.

[0011] A further improvement of the technical solution of the present invention is that: a protective ring is movably connected to the outer side of the display stand, the protective ring is ring-shaped and made of lightweight material, the inner diameter of the protective ring is larger than the outer diameter of the display stand, and a plurality of push rods are fixedly connected to the bottom of the protective ring. The outside of each push rod is movably connected to a sleeve, one end of the sleeve is fixedly connected to the bottom of the inner cavity of the base through an electromagnet, and the push rod can push the protective ring up or down along the sleeve.

[0012] A further improvement of the technical solution of the present invention is that one end of the push rod located inside the sleeve is fixedly connected to a limit block, a second spring is sleeved on the outer surface of the push rod located inside the sleeve, and the limit block is made of metal material.

[0013] A further improvement of the technical solution of the present invention is that when a ceramic handicraft is placed on a display stand, the electromagnet is energized to produce a magnetic attraction on the limit block, so that the limit block is at the bottom. At this time, the second spring is in a stretched state. When the ceramic handicraft falls over, the electromagnet is de-energized, the magnetic attraction disappears, and the push rod rebounds and rises under the action of the second stretch spring, pushing the protective ring to rise to a certain height, thereby forming a protective effect for the fallen ceramic handicraft.

[0014] A further improvement of the technical solution of the present invention is that: a plurality of trigger rods are movably connected along the circumference of the fixed groove on the outer surface of the display stand. When the ceramic handicraft is not placed on the display stand, the trigger rods are higher than the upper surface of the display stand. When the ceramic handicraft is placed on the display stand and the plurality of trigger rods, the trigger rods slide downward under the action of gravity. At this time, the circuit of the electromagnet is connected, and the limit block is attracted downward, so that the protective ring is at a position lower than the display stand. When the ceramic handicraft falls over, the pressure on the trigger rod at any circumferential position disappears, and the trigger rod moves upward, so that the connection circuit of the electromagnet is disconnected, that is, the magnetic attraction of the electromagnet disappears, and the push rod rebounds and rises under the action of the second tension spring, which can push the protective ring to a certain height.

[0015] A further improvement of the technical solution of the present invention is that: the bottom of each trigger rod is fixedly connected to a movable electrode end, the bottom of each movable electrode end is movably connected to a fixed slip ring, the fixed slip ring is fixedly connected to the bottom of the display stand through a fixed frame, each movable electrode end is electrically connected to an adjacent fixed slip ring through a wire five, multiple movable electrode ends and fixed slip rings are connected in series, the movable electrode end and the fixed slip ring at the end are electrically connected to a wire four and a wire three, respectively, one end of the wire four is electrically connected to a power supply device, and the power supply device is fixedly connected to the bottom of the inner cavity of the base.

[0016] The multiple electromagnets are connected in series in sequence through a first conductor, an electromagnet at an end is electrically connected to one end of a third conductor, and another electromagnet at an end is electrically connected to a power supply device through a second conductor.

[0017] A further improvement of the technical solution of the present invention is that: a connecting ear plate is fixedly connected to the outer surface of the movable electrode end, a sliding rod is movably connected through the connecting ear plate, and the two ends of the sliding rod are respectively fixedly connected to the bottom of the display stand and the fixed frame, and a spring is sleeved on the outer surface of the sliding rod located between the connecting ear plate and the fixed frame.

[0018] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0019] 1. The present invention provides a protective display base for ceramic handicrafts. When displaying, the ceramic handicraft is placed on the display stand and the fixing groove is covered inside. Since the upper surface of the suction cup is slightly higher than the upper surface of the display stand, a part of the suction cup is outside the fixing groove. The suction cup is made of soft material and can undergo a certain degree of elastic deformation. Therefore, after the ceramic handicraft is placed, a certain pressure will be generated on the suction cup, so that the edge of the suction cup is tightly attached to the bottom of the ceramic handicraft, forming a closed cavity. Then, through the action of the gas processing mechanism, the gas in the cavity is reduced to form a negative pressure cavity. Under the action of atmospheric pressure, the suction cup will further deform and form a tighter connection with the bottom of the ceramic handicraft. At this time, while ensuring the stability of the placement of the ceramic handicraft, the viewing effect can also be guaranteed, avoiding the problem of conventional clamping devices blocking the ceramic handicraft body.

[0020] 2. The present invention provides a base for protecting and displaying ceramic handicrafts. In the initial stage, the piston plate is at the top and the lifting rod is in an extended state. When the suction cup is tightly in contact with the bottom of the ceramic handicraft, the piston plate can be driven downward by the lifting rod. When the viewing is over, the piston plate can be driven upward by the lifting rod to move to its original position. At this time, the air pressure inside and outside the suction cup cavity is balanced, and the ceramic handicraft can be removed.

[0021] 3. The present invention provides a protective display base for ceramic handicrafts. During normal viewing time, most of the push rod is located inside the sleeve, and the protective ring is at a position slightly lower than the display stand, so that the viewing of the ceramic handicrafts placed on the display stand is not affected. When the ceramic handicrafts fall over, the push rod rises along the inner wall of the sleeve and raises the protective ring to a certain height, forming a ring-shaped protective effect for the fallen ceramic handicrafts.

DETAILED DESCRIPTION

[0031] The present invention is described in further detail below in conjunction with the embodiments:

[0032] Example:

[0033] like Figure 1-8As shown, the present invention provides a ceramic handicraft protection and display base, including a display stand 1, the bottom of the display stand 1 is fixedly connected to a base 2 through a plurality of support rods 12, the top of the base 2 is fixedly connected to a protective cover 3, the top of the protective cover 3 is movably connected to a cover plate 4, and the protective cover 3 and the cover plate 4 are both made of transparent materials.

[0034] A fixing groove 5 is provided in the middle of the display stand 1, and a suction cup 6 is movably connected inside the fixing groove 5. The upper surface of the suction cup 6 is higher than the upper surface of the display stand 1. The suction cup 6 is made of soft material. The bottom end of the suction cup 6 is fixedly connected to the lower surface of the display stand 1 through a plurality of fixing rods 7. A gas processing mechanism is provided at the bottom of the suction cup 6.

[0035] During display, the ceramic craft is placed on the display stand 1 and the fixing groove 5 is covered. Since the upper surface of the suction cup 6 is slightly higher than the upper surface of the display stand 1, a part of the suction cup 6 is outside the fixing groove 5, and the suction cup 6 is made of soft material and can undergo a certain degree of elastic deformation. Therefore, after the ceramic craft is placed, a certain pressure will be generated on the suction cup 6, so that the edge of the suction cup 6 is tightly attached to the bottom of the ceramic craft, forming a closed cavity. Then, through the action of the gas treatment mechanism, the gas in the cavity is reduced to form a negative pressure cavity. Under the action of atmospheric pressure, the suction cup 6 will further deform and form a tighter connection with the bottom of the ceramic craft. At this time, while ensuring the stability of the placement of the ceramic craft, the viewing effect can also be guaranteed, avoiding the problem of conventional clamping devices blocking the ceramic craft body.

[0036] Furthermore, the gas processing mechanism includes an air pipe 8 fixedly connected to the bottom of the suction cup 6, one end of the air pipe 8 is fixedly connected to the gas tank 9, the suction cup 6, the air pipe 8, and the interior of the gas tank 9 are connected through the air, and a piston plate 10 is movably connected to the inner wall of the gas tank 9. The piston plate 10 can slide up and down along the inner wall of the gas tank 9. When the suction cup 6 is tightly abutted against the bottom of the ceramic craft, the piston plate 10 moves downward along the inner wall of the gas tank 9, and the gas in the cavity will be diverted to the gas tank 9 through the air pipe 8, and the gas volume will increase. The gas volume is inversely proportional to the gas pressure. Therefore, the pressure in the cavity of the suction cup 6 decreases. Under the action of atmospheric pressure, the suction cup 6 is tightly connected to the bottom of the ceramic craft.

[0037] Furthermore, a lifting rod 11 is fixedly connected to the bottom of the inner cavity of the gas storage tank 9, and the output end of the lifting rod 11 is fixedly connected to the piston plate 10. In the initial stage, the piston plate 10 is at the top and the lifting rod 11 is in an extended state. When the suction cup 6 is tightly abutted against the bottom of the ceramic handicraft, the piston plate 10 can be driven downward by the lifting rod 11. When the viewing is over, the piston plate 10 can be driven to move up to its original position by the lifting rod 11. At this time, the air pressure inside and outside the cavity of the suction cup 6 is balanced, and the ceramic handicraft can be removed.

[0038] Furthermore, a protective ring 20 is movably connected to the outer side of the display stand 1. The protective ring 20 is annular and made of lightweight material. The inner diameter of the protective ring 20 is larger than the outer diameter of the display stand 1. A plurality of push rods 21 are fixedly connected to the bottom of the protective ring 20. The outside of each push rod 21 is movably connected to a sleeve 22. One end of the sleeve 22 is fixedly connected to the bottom of the inner cavity of the base 2 through an electromagnet 25. The push rod 21 can push the protective ring 20 up or down along the sleeve 22. During normal viewing time, most of the push rod 21 is located inside the sleeve 22. At this time, the protective ring 20 is slightly lower than the display stand 1, so that the viewing of the ceramic crafts placed on the display stand 1 is not affected. When the ceramic crafts fall over, the push rod 21 rises along the inner wall of the sleeve 22 and raises the protective ring 20 to a certain height, forming a ring-shaped protective effect for the fallen ceramic crafts.

[0039] Furthermore, one end of the push rod 21 located inside the sleeve 22 is fixedly connected to a limit block 24 , a spring 23 is sleeved on the outer surface of the push rod 21 located inside the sleeve 22 , and the limit block 24 is made of metal material.

[0040] Furthermore, when the ceramic handicraft is placed on the display stand 1, the electromagnet 25 is energized to produce a magnetic attraction on the limit block 24, so that the limit block 24 is at the bottom. At this time, the spring 23 is in a stretched state. When the ceramic handicraft falls over, the electromagnet 25 is de-energized, the magnetic attraction disappears, and the push rod 21 rebounds and rises under the action of the stretched spring 23, thereby pushing the protective ring 20 to rise to a certain height, thereby forming a protective effect on the fallen ceramic handicraft.

[0041] Furthermore, a plurality of trigger rods 13 are movably connected along the circumferential direction of the fixed groove 5 on the outer surface of the display stand 1. When the ceramic craft is not placed on the display stand 1, the trigger rod 13 is higher than the upper surface of the display stand 1. When the ceramic craft is placed on the display stand 1 and the plurality of trigger rods 13, the trigger rod 13 slides downward under the action of gravity. At this time, the connection circuit of the electromagnet 25 is connected, and the limit block 24 is adsorbed downward, so that the protective ring 20 is at a position lower than the display stand 1, ensuring that the viewing of the ceramic craft is not affected. When the ceramic craft falls over, the pressure on the trigger rod 13 at any circumferential position disappears, and the trigger rod 13 moves upward, so that the connection circuit of the electromagnet 25 is disconnected, that is, the magnetic attraction of the electromagnet 25 disappears, and the push rod 21 rebounds and rises under the action of the tension spring 23, which can push the protective ring 20 to a certain height.

[0042] Furthermore, the bottom of each trigger rod 13 is fixedly connected to a movable electrode end 14, and the bottom of each movable electrode end 14 is movably connected to a fixed slip ring 15. The fixed slip ring 15 is fixedly connected to the bottom of the display stand 1 through a fixed frame 16. Each movable electrode end 14 is electrically connected to the adjacent fixed slip ring 15 through a wire five 31. Multiple movable electrode ends 14 and fixed slip rings 15 are connected in series. The movable electrode ends 14 and fixed slip rings 15 located at the end are electrically connected to a wire four 30 and a wire three 29, respectively. One end of the wire four 30 is electrically connected to a power supply device 28, and the power supply device 28 is fixedly connected to the bottom of the inner cavity of the base 2.

[0043] Multiple electromagnets 25 are connected in series in sequence through wire 1 26 , one electromagnet 25 at the end is electrically connected to one end of wire 3 29 , and another electromagnet 25 at the end is electrically connected to the power supply device 28 through wire 2 27 .

[0044] In the initial stage, when the ceramic handicraft is placed on the display stand 1 and multiple trigger rods 13, under the action of gravity, the trigger rod 13 slides downward, and the movable electrode end 14 and the connecting ear plate 17 move downward simultaneously along the slide rod 18 and are connected to the fixed slip ring 15. At this time, the spring 19 is in a compressed state, and the connection circuit of the electromagnet 25 is connected, which adsorbs the limit block 24 downward so that the protective ring 20 is lower than the display stand 1, ensuring that the viewing of the ceramic handicraft is not affected. When the ceramic handicraft falls over, the pressure on the trigger rod 13 at any circumferential position disappears. Under the action of the compression spring 19, the trigger rod 13 and the movable electrode end 14 move upward and separate from the electromagnet 25, so that the connection circuit of the electromagnet 25 is disconnected, that is, the magnetic attraction of the electromagnet 25 disappears, and the push rod 21 rebounds and rises under the action of the tension spring 23, pushing the protective ring 20 to a certain height, thereby forming a protective effect on the fallen ceramic handicraft.

[0045] Under the action of gravity of the ceramic handicraft, multiple trigger rods 13 and movable electrode ends 14 move downward at the same time, and are electrically connected to multiple fixed slip rings 15 respectively, and cooperate with the action of multiple series-connected electromagnets 25. At this time, multiple movable electrode ends 14, fixed slip rings 15, and electromagnets 25, under the action of multiple wires, together constitute a complete series circuit, which is characterized in that: multiple movable electrode ends 14 move downward at the same time, the circuit is connected, and any movable electrode end 14 separated from the fixed slip ring 15 will cause the series circuit to be disconnected. Correspondingly, when the ceramic handicraft tips over at any angle, the pressure on any movable electrode end 14 will disappear, and the movable electrode end 14 will move upward and separate from the fixed slip ring 15, that is, the connection circuit of the electromagnet 25 will be disconnected, so that the protective ring 20 can rebound and rise to a certain height under the action of the stretched spring 23, thereby protecting the ceramic handicraft.

[0046] Furthermore, a connecting ear plate 17 is fixedly connected to the outer surface of the movable electrode end 14, and a sliding rod 18 is movably connected to the connecting ear plate 17. The two ends of the sliding rod 18 are respectively fixedly connected to the bottom of the display stand 1 and the fixed frame 16. The outer surface of the sliding rod 18 is located between the connecting ear plate 17 and the fixed frame 16, and a spring 19 is sleeved on the outer surface. The trigger rod 13, the movable electrode end 14 and the connecting ear plate 17 move downward along the sliding rod 18 under the action of the gravity of the ceramic handicraft and are connected to the fixed slip ring 15. The electromagnet 25 is connected to the circuit and compresses the spring 19 to cause it to undergo elastic deformation. When the ceramic handicraft falls over, the trigger rod 13, the movable electrode end 14 and the connecting ear plate 17 thereat rebound under the action of the compressed spring 19, the movable electrode end 14 is separated from the fixed slip ring 15, and the electromagnet 25 connection circuit is disconnected.
