Description
Technical Field
[0001] This utility model relates to the field of display rack technology, and in particular to a lifting clay sculpture display rack. Background Technology
[0002] In recent years, with the rise of cultural and museum exhibitions, campus aesthetic education, and the hands-on experience economy, clay sculpture exhibits have frequently moved between various venues. The supports for these works have gradually evolved towards lightweight and mobile designs. Portable structures such as folding metal frames and wheeled wooden bases have become standard features in exhibition halls and workshops, providing initial flexibility for exhibit arrangement.
[0003] Existing technologies mostly use scissor lift platforms or single-point set screw sleeves as height adjustment mechanisms, with flat tabletops to support the artwork; movement relies on external caster bases, and locking is achieved by lateral tightening of knobs or positioning of pins with holes; the tabletop and lifting rods are usually welded together, and rotation requires lifting the entire piece or multiple people to twist the support.
[0004] However, the above solutions reveal common problems in scenarios with frequent exhibition changes, such as multiple adjustment steps, easy loosening of locks, and inability to rotate or quickly replace the platform, making it difficult to meet the comprehensive needs of clay sculpture displays for instant height fine-tuning, stable suspension, and flexible orientation changes. Utility Model Content
[0005] The purpose of this utility model is to propose a lifting clay sculpture display rack to solve the problems of cumbersome height adjustment, unstable locking, and inability to quickly rotate or replace the platform of existing display racks.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A lifting clay sculpture display rack includes a tripod with casters fixedly mounted at the bottom; a nut, which is radially and vertically positioned in the middle of the tripod; a screw rod, which is threaded into the nut, and a platform is fixedly mounted on the top of the screw rod; a locking device, which is installed inside the tripod to lock the screw rod after it is raised or lowered; and a quick-connect device, through which the platform is detachably mounted on the top of the screw rod.
[0007] By adopting the above technical solutions, the casters enable convenient overall relocation, the nut-screw pair provides stepless lifting, the locking mechanism instantly locks the height, and the quick-connect parts allow the platform to rotate independently or be quickly detached, thus completing the functions of moving, lifting, locking, reversing, and platform replacement in one go. Furthermore, the tripod has at least three legs, nuts are fixedly mounted on the top of the three legs, a support beam is provided between the three legs, a crossbeam is provided between two legs, and a locking element is fixedly mounted on the crossbeam and surrounds the side of the screw rod.
[0008] By adopting the above technical solution, the crossbeam provides a rigid mounting position for the locking component, and the support beam enhances the overall torsional resistance of the tripod, preventing the frame from swaying during lifting and lowering.
[0009] Furthermore, a caster is installed at the bottom of each outrigger, and a disc is welded to the top of the three outriggers. The disc has a through hole for the screw to pass through, and a nut is welded to the top of the disc, with the nut coinciding with the central axis of the through hole.
[0010] By adopting the above technical solution, the disc unifies the positioning reference of each leg, and the through hole and nut are coaxial to ensure the straightness of the screw lifting and lowering, reducing the risk of jamming.
[0011] Furthermore, the nut is divided into an upper nut and a lower nut. The upper nut is installed on the top of the three outriggers, and the lower nut has a connecting rod extending from its side toward the outriggers. The connecting rod is fixedly installed on the side of the outriggers.
[0012] By adopting the above technical solution, the spacing between the two nuts forms two-point support, and the connecting rod transmits the force of the lower nut to the support leg, which significantly reduces the cantilever length of the screw and prevents bending caused by eccentric load.
[0013] Furthermore, the locking component includes a sleeve surrounding the screw, a support rod fixedly mounted on the sleeve and connected to the support leg, an abutment plate extending outward from the side of the sleeve, and a bolt threaded onto the crossbeam for adjusting the position of the abutment plate.
[0014] By adopting the above technical solution, rotating the bolt can push the abutment plate to make the round sleeve tighten or loosen the screw, and locking and releasing can be completed with one hand, improving the efficiency of the exhibition setup.
[0015] Furthermore, an expansion joint is provided on the circular sleeve, and the bolt pushes the abutment plate to control the expansion and contraction of the expansion joint.
[0016] By adopting the above technical solution, the expansion joint provides elastic deformation space for the sleeve, so that the clamping force is evenly distributed and local overpressure damage to the screw surface is avoided.
[0017] Furthermore, the quick-connect component includes a rotating sleeve fixedly installed at the bottom of the platform, a limiting sleeve threadedly connected to the outside of the rotating sleeve, and a clamp rotatably installed at the bottom end of the rotating sleeve. The outer side of the clamp is an outwardly inclined surface, the bottom of the limiting sleeve abuts against the inclined surface, and the rotating sleeve is inserted into the top of the screw.
[0018] By adopting the above technical solution, the downward rotation of the limiting sleeve compresses the inclined surface, causing the clamp to retract synchronously, thus instantly securing the platform and the screw; the reverse rotation loosens the screw, allowing the platform to rotate freely around the screw axis or be pulled upwards, achieving orientation adjustment and quick replacement.
[0019] Compared with the prior art, the present invention has the following beneficial effects: The lifting clay sculpture display rack described in this utility model utilizes a nut-screw pair to achieve stepless lifting, and is instantly locked with a locking component, eliminating the tedious steps of repeatedly inserting pins or tightening and loosening knobs; the double nut and connecting rod structure distributes the load, prevents the screw from bending, and ensures smooth lifting and reliable locking; the circular sleeve expansion joint design ensures uniform locking force, avoids local damage, and extends service life; the quick-connect component integrates clamping, rotating, and disassembling, allowing the platform to be quickly reversed or replaced as a whole with one hand, significantly improving exhibition efficiency and exhibit adaptability.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] This embodiment relates to a lifting clay sculpture display rack, the overall structure of which is as follows: Figure 1 and Figure 3 As shown, it includes a tripod 1, a nut, a screw 5, a platform 6, a locking component 7, and a quick-connect component 8.
[0028] The tripod 1 is fixedly equipped with casters 101 at its bottom. A nut is vertically positioned radially in the middle of the tripod 1, and a screw rod 5 is threaded into the nut. A locking device 7 is installed on the tripod 1 to lock the screw rod 5 after it has been raised or lowered. A platform 6 is provided for placing clay sculptures, and the platform 6 is detachably installed on top of the screw rod 5 via a quick-connect fitting 8.
[0029] It is worth mentioning that the casters 101 facilitate the movement of the display stand. The nut is welded to the top of the tripod 1, and the screw 5 rotates and rises within the nut, thus facilitating the adjustment of the height of the platform 6. After the height adjustment of the screw 5 is installed, the locking piece 7 can lock the screw 5 in the raised or lowered position. The platform 6 is a flat plate, and the clay sculpture is placed on the platform 6. The quick-connect piece 8 is fixedly installed at the bottom of the platform 6. The quick-connect piece 8 is inserted into the top of the screw 5 and tightened on the screw 5. This setting ensures that after the quick-connect piece 8 is loosened, the platform 6 can rotate around the screw 5 as the axis, which is convenient for controlling the direction of the platform 6. It also allows the platform 6 to be removed from the screw 5 for easy replacement.
[0030] Based on the above overall introduction, an exemplary structure of this embodiment is as follows: Figure 2As shown, the tripod 1 has at least three legs 102 for support, nuts are fixedly disposed on the top of the three legs 102, a support beam 103 is disposed between the three legs 102, a crossbeam 104 is disposed between two legs 102, and a locking member 7 is fixedly disposed on the crossbeam 104 and surrounds the side of the screw 5.
[0031] Specifically, the three legs 102 form a triangle, with a caster 101 installed at the bottom of each leg 102. A disc 105 is welded to the top of the three legs 102, and a through hole 106 is opened on the disc 105 for the screw 5 to pass through. A nut is welded to the top of the disc 105, and the nut coincides with the central axis of the through hole 106 to ensure that the screw 5 can rise and fall on the disc 105. The support beam 103 connects the three legs 102, thereby improving the strength of the tripod 1. The crossbeam 104 is located on the upper part of the support beam 103, and the locking member 7 is installed on the crossbeam 104. The screw 5 can be locked by controlling the locking member 7.
[0032] As a preferred option, such as Figure 4 As shown, in this embodiment, the nuts are divided into upper nuts 2 and lower nuts 3. The upper nuts 2 are installed on the top of the three support legs 102, and the lower nuts 3 are installed between the three support legs 102. A connecting rod 4 is fixedly installed on the side of the lower nuts 3, and the connecting rod 4 is fixedly installed on the side of the support legs 102.
[0033] Specifically, the upper nut 2 and the lower nut 3 are arranged vertically, and the screw 5 is threaded into the upper nut 2 and the lower nut 3 respectively. This arrangement ensures the strength of the screw 5 and avoids tilting caused by uneven force on the screw 5. The connecting rod 4 on the lower nut 3 extends toward the support leg 102 and is welded and fixed to the support leg 102. This arrangement ensures that the upper nut 2 and the lower nut 3 are coaxially set, and the arrangement of the two nuts can prevent the screw 5 from tilting.
[0034] As a preferred implementation method, such as Figure 4 As shown, the locking component 7 in this embodiment includes a circular sleeve 701 surrounding the screw 5, a support rod 702 fixedly mounted on the circular sleeve 701 and connected to the support leg 102, an abutment plate 703 extending outward from the side of the circular sleeve 701, and a bolt 704 threadedly connected to the crossbeam 104 for adjusting the position of the abutment plate 703. It should be noted that a threaded hole can be opened in the crossbeam 104, or an adjusting nut can be welded to the crossbeam 104. An expansion joint 705 is provided on the circular sleeve 701. By rotating the bolt 704, the bolt 704 contacts the abutment plate 703, pushing the inner diameter of the circular sleeve 701 to decrease, thereby clamping the screw 5. The expansion joint 705 allows for changes in the diameter of the circular sleeve 701, thus achieving locking.
[0035] As a preferred implementation method, such as Figure 5 and Figure 6As shown, the quick-connect component 8 in this embodiment includes a rotating sleeve 801 fixedly disposed at the bottom of the platform 6, a limiting sleeve 802 threadedly connected to the outside of the rotating sleeve 801, and a clamp 803 rotatably disposed at the bottom end of the rotating sleeve 801. The outer side of the clamp 803 is an outwardly inclined surface, and the bottom of the limiting sleeve 802 abuts against the inclined surface. It should be noted that the top of the rotating sleeve 801 is welded to the bottom surface of the platform 6, and the bottom of the rotating sleeve 801 is inserted into the top of the screw 5. At least three clamps 803 are provided around the rotating sleeve 801. The limiting sleeve 802 rotates and moves on the rotating sleeve 801, and after abutting against the inclined surface of the clamp 803, it can abut the clamp 803 against the screw 5, thereby fixing the screw 5 and the platform 6. The locking component 7 fixes the screw 5, and the screw 5 fixes the platform 6. This arrangement ensures the stability of the clay sculpture. When the clamp 803 is released, the platform 6 can rotate, which facilitates the adjustment of the direction of the clay sculpture.
[0036] The lifting clay sculpture display rack in this embodiment uses a nut-screw pair of 5 to achieve stepless lifting, and locks instantly with locking component 7, eliminating the tedious steps of repeatedly inserting pins or tightening and loosening knobs; the double nut plus connecting rod 4 structure distributes the load, prevents the screw 5 from bending, and ensures smooth lifting and reliable locking; the circular sleeve 701 and expansion joint 705 design make the locking force uniform, avoid local damage, and extend service life; the quick connector 8 integrates clamping, rotating, and disassembling, and the platform 6 can be quickly reversed or replaced as a whole with one hand, significantly improving the efficiency of display and the adaptability of exhibits.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
