Description
Technical Field
[0001] This disclosure pertains to the field of waterproof display racks, specifically relating to a waterproof cover for an outdoor innovative and entrepreneurial display rack. Background Technology
[0002] With the booming development of outdoor innovation and entrepreneurship activities, display equipment needs to adapt to complex and ever-changing open-air environments. In particular, how to ensure the safety and display continuity of core components such as electronic screens and promotional materials in windy and rainy weather has become a pain point in the industry.
[0003] However, traditional outdoor display racks often use fixed rain shelters or electric retractable covers. The former has the problem of non-adjustable coverage area and low space utilization, while the latter relies on electric drive and has a complex mechanical structure. Moreover, electric drive requires manual control of the switch. If the staff does not open the retractable cover switch in time during the explanation, the display equipment may be damaged by moisture, affecting the display effect. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide a waterproof cover for an outdoor innovation and entrepreneurship display rack, which solves the problem that the waterproof cover cannot be deployed in time when it suddenly rains outdoors and the staff is not next to the display rack.
[0005] The objective of this disclosure can be achieved through the following technical solutions:
[0006] A waterproof cover for an outdoor innovation and entrepreneurship display rack includes: a display stand, a waterproof cover, and a gravity adjustment component;
[0007] A waterproof cover is fixed to the upper end of the display stand, and extension frames are slidably provided on both sides of the waterproof cover. A gravity adjustment component is fixed to the center of the upper end of the waterproof cover.
[0008] The gravity adjustment assembly includes a screw, a nut seat, a connecting rod, and a counterweight. The upper end of the waterproof cover is threadedly connected to the screw, and the upper end of the screw is fixed with a nut seat. At least one connecting rod is arranged around the outside of the nut seat, and a counterweight is fixed to the end of the connecting rod away from the nut seat.
[0009] The lower end of the screw is provided with a hydraulic flow channel that connects to the diffracting frame.
[0010] In some disclosures, the display stand is fixed to a support frame at its bottom, and the support frame is fixed to a support base at its bottom.
[0011] In some disclosures, the waterproof cover has a positioning hole that penetrates through the center of its inner side, and the waterproof cover has a herringbone structure.
[0012] In some disclosures, the extension frame is located on both sides of the display stand, and the extension frame includes a support rod, a support plate, and a waterproof plate. The waterproof plate is slidably disposed on the inner side of the waterproof cover, and the support rod is disposed parallel to the lower end of the waterproof plate. The support plate is disposed parallel to the lower end of the support rod, and the support rod, the support plate, and the waterproof plate are fixedly connected.
[0013] In some disclosures, the hydraulic flow channel is a three-way pipe structure, which includes a vertical axial channel and a horizontal radial channel that are interconnected. The vertical axial channel is coaxial with the screw, while the horizontal radial channel is arranged collinearly with the axes of the two support rods.
[0014] In some disclosures, a piston block is fixed to one end of the support rod near the screw, and the piston block is in a sealed sliding fit with the hydraulic flow channel.
[0015] In some disclosures, a guide plate perpendicular to the connecting rod is fixed to the upper end face of the connecting rod.
[0016] In some disclosures, the counterweight is described as being made of rubber.
[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0018] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;
[0019] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.
[0020] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.
[0021] A sliding connection is a connection between parts that allows the parts to slide against each other.
[0022] The beneficial effects of this disclosure are:
[0023] 1. Through the linkage structure design of the counterweight and the connecting rod, natural wind energy can be used as the driving force to realize the automatic extension and retraction adjustment of the waterproof cover, which avoids the complex structure of the power device and ensures environmental adaptability.
[0024] 2. Combining the bidirectional symmetrical pressure transmission characteristics of the three-way hydraulic flow channel, the two-sided support rods are precisely controlled to expand outward synchronously during the screw pressing process, so that the extension plate slides out smoothly from the waterproof cover to form a continuously extending rainproof interface. This not only achieves a proportional expansion of the display stand's coverage area to cope with different rain conditions, but also lowers the center of gravity of the display stand and improves its anti-overturning ability under strong winds.

Detailed Implementation
[0033] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0034] Based on the concept of this application, combined with Figures 1 to 6 This document describes an embodiment of a waterproof cover for an outdoor innovation and entrepreneurship display rack. Specifically, this waterproof cover is constructed as a split structure, comprising three components: a display platform 1, a waterproof cover 3, and a gravity adjustment assembly 5. Through the linkage structure design of the counterweight 54 and the connecting rod 53, natural wind energy can be used as the driving force to achieve automatic extension and retraction adjustment of the waterproof cover 3, avoiding the complex structure of electrical devices while ensuring environmental adaptability.
[0035] Please refer to Figures 1 to 6 A waterproof cover for an outdoor innovation and entrepreneurship display rack includes: a display stand 1, a waterproof cover 3, and a gravity adjustment component 5;
[0036] A waterproof cover 3 is fixed to the upper end of the display stand 1, and extension frames 4 are slidably installed on both sides of the waterproof cover 3. A gravity adjustment component 5 is fixed to the center of the upper end of the waterproof cover 3.
[0037] The gravity adjustment component 5 includes a screw 51, a nut seat 52, a connecting rod 53 and a counterweight 54. The upper end of the waterproof cover 3 is threadedly connected to the screw 51, and the upper end of the screw 51 is fixed with the nut seat 52. At least one connecting rod 53 is arranged around the outside of the nut seat 52, and the end of the connecting rod 53 away from the nut seat 52 is fixed with the counterweight 54.
[0038] The lower end of the screw 51 is provided with a hydraulic flow channel 6 that is connected to the derrick 4.
[0039] In use, the display stand 1 is placed on a flat surface. During windy or rainy weather, staff may be talking under umbrellas and unable to pay close attention to the display stand 1. At this time, the natural wind causes multiple counterweights 54 and connecting rods 53 to rotate around the central axis of the screw 51, causing the screw 51 to screw into the nut seat 52. Simultaneously, as the screw 51 moves downwards, it causes the damping fluid in the hydraulic channel 6 to expand outwards, pushing the extension frame 4 at the lower end of the hydraulic channel 6 to slide to both sides. This increases the overall length of the waterproof cover 3, increasing the coverage area of the display stand 1 and effectively preventing rainwater intrusion. The linkage structure design of the counterweight 54 and the connecting rod 53 can sense changes in environmental wind force in real time and use natural wind energy as a driving force to realize the automatic extension and retraction adjustment of the waterproof cover 3. This avoids the complex structure of the power device and ensures environmental adaptability. At the same time, the synergistic effect of the hydraulic channel 6 and the damping fluid forms a progressive buffer mechanism, which effectively absorbs the impact load generated by sudden wind force changes while ensuring the smooth unfolding of the extension frame 4. This prevents damage to the mechanical structure due to instantaneous overload. Meanwhile, the overall height of the screw 51 decreases during the screwing process, which helps to lower the center of gravity of the device and improve its stability.
[0040] In some embodiments, a circular support frame may be provided below the connecting rod 53 to provide additional upward support for the connecting rod 53, enhance structural stability, and improve the stability of the movement of the connecting rod 53.
[0041] Please refer to Figure 1 and Figure 4The display stand 1 has a support frame 2 fixed to its bottom, and a support base 21 is fixed to the bottom of the support frame 2. The lower end of the support base 21 is in contact with the ground, and the support frame 2 is located in the middle of the display stand 1 and is in the same vertical plane as the central axis of the display stand 1. This effectively supports the display stand 1 and the entire device, ensuring the stability of the structure. In addition, the waterproof cover 3 at the top of the display stand 1 is designed with air circulation in mind to avoid wind pressure under strong winds, which could affect the stability of the device.
[0042] Please refer to Figure 1 and Figure 2 The waterproof cover 3 has a positioning hole 31 through the center of its inner side, and the waterproof cover 3 has a herringbone structure with sloping sides to help rainwater slide off quickly and reduce water pressure. The hydraulic channel 6 passes through the positioning hole 31 and connects with the screw 51, thus facilitating the positioning of the hydraulic channel 6.
[0043] Please refer to Figure 4 The hydraulic flow channel 6 is a three-way pipe structure. The hydraulic flow channel 6 includes a vertical axial channel and a horizontal radial channel that are interconnected. The vertical axial channel is coaxial with the screw 51, while the horizontal radial channel is arranged collinearly with the axis of the support rods 41 on both sides.
[0044] In use, the lower end of the screw 51 is sealed to the vertical axial channel in the hydraulic flow channel 6. When the screw 51 moves downward, the damping fluid in the vertical axial channel is compressed into the horizontal radial channel, and pushes the extension frames 4 on both sides of the horizontal radial channel to expand outward, further increasing the coverage of the waterproof cover 3. Since the vertical axial channel is in the middle of the horizontal axial channel, the damping fluid is evenly distributed in the horizontal radial channel, ensuring the symmetrical unfolding of the extension frames 4, enhancing the overall stability of the waterproof cover 3, effectively preventing the deviation caused by uneven wind force, and improving the reliability of the device in complex environments.
[0045] Please refer to Figure 1 , Figure 2 and Figure 6The extension frame 4 is located on both sides of the display stand 1, and the extension frame 4 includes a support rod 41, a support plate 42 and a waterproof plate 43. The waterproof plate 43 is slidably arranged on the inner side of the waterproof cover 3, and the support rod 41 is arranged parallel to the lower end of the waterproof plate 43. The support plate 42 is arranged parallel to the lower end of the support rod 41. The support rod 41, the support plate 42 and the waterproof plate 43 are fixedly connected. The support rod 41 on the extension frame 4 slides into the horizontal radial channel on the hydraulic channel 6. When the damping fluid in the vertical axial channel of the hydraulic channel 6 is compressed into the horizontal radial channel, the damping fluid pushes the support rod 41 on the extension frame 4 to move outward, causing the support plate 42 and the waterproof plate 43 to unfold synchronously. The support plate 42 is used to improve the unfolding stability of the waterproof plate 43, ensuring its wind pressure resistance and drainage performance in strong wind and rain environments. Furthermore, the support rod 41, support plate 42, and waterproof plate 43 are arranged in parallel, so that when the extension frame 4 slides outward, the movement trajectories of the support rod 41, support plate 42, and waterproof plate 43 will not interfere with each other and cause jamming.
[0046] Please refer to Figure 4 and Figure 6 A piston block 411 is fixed to one end of the support rod 41 near the screw 51. The piston block 411 is in a sealed sliding fit with the hydraulic flow channel. The piston block 411 helps to improve the transmission efficiency of the damping fluid and ensures that the pressure in the hydraulic flow channel 6 is evenly distributed.
[0047] Please refer to Figures 1 to 5 A guide plate 531 perpendicular to the upper end face of the connecting rod 53 is fixed thereon. The guide plate 531 increases the area of the connecting rod 53, thereby improving the force distribution of the wind on the connecting rod 53, reducing local stress concentration, and enhancing wind resistance.
[0048] The counterweight 54 is made of rubber, which has good elasticity and wear resistance, effectively absorbing the impact of wind and vibration, further stabilizing the entire device. Furthermore, when counterweight 54 impacts the audience, it will not cause serious injury; its softness also provides cushioning, reducing the risk of accidents and improving safety.
[0049] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the waterproof cover for an outdoor innovation and entrepreneurship display rack provided by this utility model.
[0050] When in use, the lower end face of the support base 21 is in contact with the ground. The support base 21 is fixed by anchor bolts, and the display stand 1 is facing the audience. When encountering windy or rainy weather, the natural wind in the environment drives multiple guide plates 531 and connecting rods 53 to rotate around the central axis of the screw 51. While the connecting rod 53 is rotating, it drives the counterweight block 54 and the screw 51 to rotate, so that the screw 51 is screwed into the nut seat 52 through its own threads during the rotation process.
[0051] Simultaneously, as the screw 51 moves downward, the damping fluid in the vertical axial channel of the hydraulic flow channel 6 is compressed into the horizontal radial channel, and pushes the support rod 41 in the horizontal radial channel to slide to both sides in the horizontal direction, and pushes the waterproof plate 43 to slide out of the waterproof cover 3, thereby increasing the overall length of the waterproof cover 3 and increasing the coverage area of the display stand 1, which is beneficial to improving the display effect and audience experience.
