[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an element in the middle at the same time. In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments, such as "inside", "outside", "left", "right" and similar expressions are only for the purpose of explanation and are not intended to limit the present invention.

[0022] Please refer to Figures 1 to 4 , is a schematic diagram of a display cabinet lifting device 100 of the utility model, and the display cabinet lifting device 100 is installed on a display cabinet for use. The display cabinet lifting device 100 includes a main frame 20 and a lifting cover mechanism 30 installed on the main frame 20. When installed, the lower end of the main frame 20 is partially sunken and located in the installation groove, which can reduce the overall space occupation and is conducive to installation and use in museums and cultural relics halls with limited space.

[0023] Furthermore, the lifting cover mechanism 30 includes a driving motor 31, a threaded rod 32, a lifting platform 33, at least three guide rods 34, and a lifting cover 35 installed on the main support 20. The driving motor 31 is connected to the threaded rod 32, the threaded rod 32 is threadedly connected to the lifting platform 33, the lower end of the guide rod 34 is fixedly connected to the lifting platform 33, and the upper end of the guide rod 34 is fixedly connected to the lifting cover 35. The lifting cover 35 has a circular cross-section and is made of transparent explosion-proof tempered glass, which has strong protection and is convenient for observing the exhibits inside. The specific number of guide rods 34 can be set as needed, and multiple guide rods 34 are required to be distributed at equal intervals so that the guiding force is balanced.

[0024] Furthermore, the lifting cover mechanism 30 also includes a reducer 36 installed on the main support 20, and the reducer 36 is connected to the drive motor 31 and the threaded rod 32 respectively, specifically, the input end of the reducer 36 is connected to the drive motor 31, and the output end of the reducer 36 is connected to the threaded rod 32. The setting of the reducer 36 can reduce the rotation speed, increase the output torque, reduce the load inertia, and thus ensure the driving stability and service life. Furthermore, a driving gear 361 is installed on the reducer 36, and a transmission gear 321 is installed on the threaded rod 32. The transmission gear 321 is meshed with the driving gear 361, and the transmission is transmitted by the meshing of the transmission gear 321 and the driving gear 361, thereby ensuring the transmission accuracy. In other embodiments, the transmission gear 321 and the driving gear 361 can also be replaced by a pulley and a transmission belt, but the accuracy guarantee will be reduced, and slippage may occasionally occur.

[0025] Furthermore, the lifting cover mechanism 30 also includes a hand wheel 37 connected to the reducer 36. The reducer 36 is driven to work by rotating the hand wheel 37, thereby driving the threaded rod 32 to rotate, thereby providing a driving force to the lifting platform 33, and finally making the lifting cover 35 move up or down. The setting of the hand wheel 37 plays a double insurance role, so that the lifting cover 35 can be manually driven to move up and down in case of power failure or failure of the driving motor 31.

[0026] Furthermore, the lifting cover mechanism 30 also includes a guide rail 38 mounted on the main frame 20, a slider seat 39 connected to the lifting platform 33, and the slider seat 39 is slidably connected to the guide rail 38. In this embodiment, there are two guide rails 38, and the threaded rod 32 is located in the middle of the guide rail 38, so that the guide support force of the guide rail 38 is evenly distributed and the guiding effect is stable.

[0027] Furthermore, the guide rail 38 is located on the side of the guide rod 34 close to the threaded rod 32, the lifting platform 33 is a rectangular platform, and the number of guide rods 34 is four. In this way, the overall structure is formed with the threaded rod 32 in the middle to provide driving force, and the guide rail 38 and the guide rod 34 provide guide support force points on the inside and outside, so that the guide support is more balanced and stable, and the service life is effectively improved.

[0028] In order to provide a guiding protection function for the guide rod 34 and reduce the friction on the outer surface of the guide rod 34, a plurality of guide sleeves 21 are installed on the main frame 20, and the guide rod 34 is arranged through the guide sleeves 21. In this embodiment, the number of the guide sleeves 21 is four.

[0029] The display cabinet lifting device 100 is connected to the drive motor 31 with the threaded rod 32, the threaded rod 32 is threadedly connected to the lifting platform 33, the lower end of the guide rod 34 is fixedly connected to the lifting platform 33, and the upper end of the guide rod 34 is fixedly connected to the lifting cover 35. When in use, the drive motor 31 can drive the threaded rod 32 to rotate and then drive the lifting platform 33 to rise and fall, and finally the lifting cover 35 is lifted and lowered, which is directly and accurately controlled by the drive motor, and does not need to be manually driven to lift and lower, which is easy to operate. In addition, at least three guide rods 34 are provided, so that the operation is more stable and not easy to shake during the lifting operation, and the stability is good.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
