Abstract
Description
Technical Field
[0001] This utility model relates to the field of outdoor products technology, specifically to an advertising exhibition tent that prevents water accumulation on the top. Background Technology
[0002] Folding tents, also known as advertising tents or sunshades, typically use high-quality fabrics that are rainproof, sunproof, durable, and easy to clean, making them suitable for all-weather use. Common tents use four top poles to support the four corners of the tent top, but the lack of supporting structures between the poles results in a looser top fabric. In rainy weather, water can accumulate on the fabric, putting pressure on the support frame and potentially causing the entire tent to collapse.
[0003] Chinese Patent Publication No. CN217652474U discloses an outdoor multifunctional waterproof tent. In rainy weather, pulling one side of the belt rotates a roller. Because the roller is fixedly connected to one end of a threaded rod and, under the action of a bearing, drives the threaded rod to rotate, the two ends of the rod have opposite threads. During rotation, the sliders at both ends retract and slide inwards, causing the top rotating shaft to move. Because the rotating shaft is rotatably connected to the bottom end of the rotating rod, the slider's movement causes the rotating rod to rotate in the opposite direction. As the rotating rod moves from an inclined position to a vertical position, it provides support to the second crossbeam at the top and causes it to rise. Simultaneously, the tent fabric is pulled taut to prevent water accumulation on the inclined top surface. When folding up, pulling the other side of the belt rotates the roller in the opposite direction, which in turn causes the threaded rod to rotate in the opposite direction, causing the slider to slide in the opposite direction. This causes the rotating shaft to move in the opposite direction, and the rotating rod rotates in the opposite direction. As the rotating rod moves from a vertical position to an inclined position, the support force on the second crossbeam decreases, and the second crossbeam descends under its own weight. The tent fabric loses external force and returns to a relaxed state. However, the tent fabric lifting device in the patent document lacks a guide device, so the lifting device may tilt during travel, which would prevent the tent fabric from being lifted.
[0004] To address this issue, the device needs to be improved to prevent it from tilting. Utility Model Content
[0005] To address the aforementioned issues, an advertising exhibition tent designed to prevent water accumulation on the top is provided. This is achieved by incorporating a guiding mechanism, which includes a guide hole and a guide rod. The guide rod is inserted into the guide hole, which is located on the base. The guide rod is mounted on the lifting block. The guide hole limits the position of the guide rod, thereby limiting the movement path of the lifting block. This solves the problem of the tent fabric failing to be lifted due to the lifting device tilting during movement.
[0006] To address the problems of existing technologies, this utility model provides an advertising exhibition tent that prevents water accumulation on the top, comprising a tent fabric and a support frame, with a lifting mechanism installed on the support frame. The lifting mechanism includes a base, a lifting block, a first moving block, a second moving block, a first rotating rod, and a second rotating rod. The base is positioned above the support frame and fixedly connected to it, and has a moving groove. The first and second moving blocks are symmetrically arranged in the moving groove about the center line of the base. One end of the first rotating rod is rotatably connected to the first moving block, and the other end is rotatably connected to the lifting block. One end of the second rotating rod is rotatably connected to the second moving block, and the other end of the second rotating rod is rotatably connected to the lifting block; when the first moving block and the second moving block move towards each other along the moving groove, the lifting block moves upward and lifts the tarpaulin; when the first moving block and the second moving block move away from each other along the moving groove, the lifting block moves downward and approaches the base; a guide mechanism is provided between the base and the lifting block; the guide mechanism includes a guide hole and a guide rod; the guide hole is opened at both ends of the base, the guide rod is set at both ends of the lifting block and fixedly connected to the guide rod, and the guide rod is inserted into the guide hole.
[0007] Preferably, the first and second movable blocks are provided with threaded holes, and a bidirectional threaded rod is rotatably connected in the movable groove; the bidirectional threaded rod is threadedly connected to the first and second movable blocks through the threaded holes.
[0008] Preferably, a limiting hole is provided at the center of the base; a rotating wheel is provided at the center of the bidirectional threaded rod, and the rotating wheel is disposed in the limiting hole.
[0009] Preferably, a belt is fitted onto the outer wall of the wheel.
[0010] Preferably, a limiting groove is formed on the inner wall of the moving groove, and limiting blocks are provided on the first moving block and the second moving block, with the limiting blocks inserted into the limiting groove.
[0011] Preferably, an auxiliary mechanism is provided between the lifting block and the support; the auxiliary mechanism includes a first rotating block, a second rotating block and an anti-collapse block; the first rotating block is disposed on the side wall of the lifting block and fixedly connected to the lifting block, the second rotating block is disposed on the upper end of the support and fixedly connected to the support; the anti-collapse block is a telescopic structure, one end of the anti-collapse block is rotatably connected to the first rotating block, and the other end of the anti-collapse block is rotatably connected to the second rotating block.
[0012] Preferably, the anti-collapse block has several gaps for light to pass through.
[0013] Preferably, a snap-fit base is provided at the rotatable connection point between the anti-collapse block and the first rotating block and the second rotating block, and the snap-fit base snaps the snap-fit block; when the snap-fit block and the snap-fit base are engaged, the anti-collapse block and the first rotating block and the second rotating block are in a rotatable connection state.
[0014] The advantages of this utility model compared to the prior art are:
[0015] 1. This utility model is equipped with a guide mechanism. The guide holes at both ends of the base cooperate with the guide rods at both ends of the lifting block to ensure that the lifting block can only move up and down in the vertical direction. This effectively solves the problem that the top part of the lifting device is easy to tilt and the tent cloth cannot be lifted smoothly in the prior art, making the tent lifting and lowering operation more reliable and ensuring the stable realization of the anti-water accumulation function.
[0016] 2. In this utility model, a bidirectional threaded rod is used in the moving groove to connect the first moving block and the second moving block with threads. Through the center limiting hole of the base, the rotating wheel, the belt sleeved on the outer wall and other structures, the moving block can be easily driven to move, thereby accurately controlling the lifting block to rise and fall. Compared with the traditional lifting device, it is more flexible in operation, can quickly respond to water accumulation, and efficiently adjust the shape of the tarpaulin to drain water.
[0017] 3. In this utility model, an auxiliary mechanism is added between the lifting block and the support frame. The telescopic anti-collapse block is combined with the rotational connection of the first moving block and the second rotating block. It can not only provide lateral support for the lifting block when lifting the tent, preventing the tent from collapsing due to external impact and maintaining the shape of the top of the tent, but also has gaps on the anti-collapse block to allow light to pass through. The snap-fit structure of the connection part is convenient for assembly and disassembly, which comprehensively improves the practicality, durability and functionality of the tent.

Detailed Implementation
[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0026] Reference Figures 1-6 As shown: An advertising exhibition tent designed to prevent water accumulation on the top includes a tent fabric 1 and a support frame 2. A lifting mechanism 4 is mounted on the support frame 2. The lifting mechanism 4 includes a base 41, a lifting block 42, a first moving block 43, a second moving block 44, a first rotating rod 45, and a second rotating rod 46. The base 41 is positioned above the support frame 2 and fixedly connected to it. A moving groove 411 is formed on the base 41. The first moving block 43 and the second moving block 44 are symmetrically arranged in the moving groove 411 about the center line of the base 41. One end of the first rotating rod 45 is rotatably connected to the first moving block 43, and the other end is rotatably connected to the lifting block 42. One end of the second rotating rod 46 is rotatably connected to... The second moving block 44 is rotatably connected, and the other end of the second rotating rod 46 is rotatably connected to the lifting block 42. When the first moving block 43 and the second moving block 44 move towards each other along the moving groove 411, the lifting block 42 moves upward and lifts the tarpaulin 1. When the first moving block 43 and the second moving block 44 move away from each other along the moving groove 411, the lifting block 42 moves downward and approaches the base 41. A guide mechanism 3 is provided between the base 41 and the lifting block 42. The guide mechanism 3 includes a guide hole 31 and a guide rod 32. The guide hole 31 is opened at both ends of the base 41, and the guide rod 32 is provided at both ends of the lifting block 42 and fixedly connected to the guide rod 32. The guide rod 32 is inserted into the guide hole 31.
[0027] The existing lifting device lacks a guiding mechanism, which may cause the top component of the lifting device to tilt during the lifting process of the tarpaulin 1, thus preventing the tarpaulin 1 from being lifted. To address this issue, the lifting mechanism 4 is activated when it is necessary to prevent water accumulation on the top of the advertising exhibition tent. Since the first moving block 43 and the second moving block 44 are symmetrically arranged in the moving groove 411 of the base 41 with the center line of the base 41 as the axis of symmetry, by controlling the first moving block 43 and the second moving block 44 to move towards each other along the moving groove 411, during the movement, because one end of the first rotating rod 45 is rotatably connected to the first moving block 43 and the other end is rotatably connected to the lifting block 42, and at the same time one end of the second rotating rod 46 is rotatably connected to the second moving block 44 and the other end is rotatably connected to the lifting block 42, the lifting block 42 will be subjected to an upward force, thereby moving upward and lifting the tarpaulin 1, changing the shape of the top of the tarpaulin 1, so that the accumulated water can slide down smoothly, achieving the purpose of preventing water accumulation; when it is not necessary to lift the tarpaulin 1, that is, when the tent is to be taken down, the first moving block 43 and the second moving block 44 are driven to move away from each other along the moving groove 411. At this time, the lifting block 42 is subjected to a downward force, moves downward and approaches the base 41. During the lifting and lowering process, the guide hole 31 of the base 41 and the guide rod 32 of the lifting block 42 play a guiding role. The guide rod is inserted into the guide hole to ensure that the lifting block 42 can only move up and down in the vertical direction, ensuring the stability and accuracy of the movement, and making the lifting and lowering operation of the tent more reliable.
[0028] Reference Figures 2-5 As shown: The first moving block 43 and the second moving block 44 are provided with threaded holes, and a bidirectional threaded rod 47 is rotatably connected in the moving groove 411; the bidirectional threaded rod 47 is threadedly connected to the first moving block 43 and the second moving block 44 through the threaded holes.
[0029] When the bidirectional threaded rod 47 rotates, the first moving block 43 and the second moving block 44 will move towards or away from each other along the axial direction of the bidirectional threaded rod 47. If the bidirectional threaded rod 47 rotates in the forward direction, it drives the first moving block 43 and the second moving block 44 to move towards each other along the moving groove 411, thereby driving the first rotating rod 45 and the second rotating rod 46 rotatably connected to it to move, so that the lifting block 42 moves upward to lift the tarpaulin 1 to prevent water accumulation at the top. If the bidirectional threaded rod 47 rotates in the reverse direction, the first moving block 43 and the second moving block 44 will move away from each other along the moving groove 411, and the lifting block 42 will move downward and approach the base 41.
[0030] Reference Figure 5 As shown: a limiting hole 412 is provided at the center of the base 41; a rotating wheel 471 is provided at the center of the bidirectional threaded rod 47, and the rotating wheel 471 is disposed in the limiting hole 412.
[0031] Since the rotating wheel 471 is located in the limiting hole 412 at the center of the base 41, the limiting hole 412 provides limiting and support for the rotating wheel 471. On the one hand, it ensures that the rotating wheel 471 can only rotate stably around the central axis without deviation or shaking, thereby ensuring the smooth rotation of the bidirectional threaded rod 47 and enabling the first moving block 43 and the second moving block 44, which are threadedly connected to the bidirectional threaded rod 47, to move along the predetermined trajectory. On the other hand, even if the tent is subjected to external impact during use, the limiting hole 412 can limit the excessive displacement of the rotating wheel 471 and prevent the bidirectional threaded rod 47 from leaving its normal working position.
[0032] Reference Figure 5 As shown: A belt 472 is fitted on the outer wall of the rotating wheel 471.
[0033] Relying on the friction between the belt 472 and the outer wall of the wheel 471, pulling the belt 472 will cause the wheel 471 to rotate, thereby causing the bidirectional threaded rod 47 to rotate. This causes the first moving block 43 and the second moving block 44, which are threadedly connected to the bidirectional threaded rod 47, to move in the corresponding directions, so as to realize the lifting block 42 and achieve the purpose of adjusting the state of the tent tarpaulin 1 to prevent water accumulation at the top.
[0034] Reference Figures 2-5 As shown: A limiting groove 48 is provided on the inner wall of the moving groove 411, and a limiting block 49 is provided on the first moving block 43 and the second moving block 44. The limiting block 49 is inserted into the limiting groove 48.
[0035] The limiting groove 48 limits and guides the limiting block 49, so that the first moving block 43 and the second moving block 44 can only move in a straight line within the moving groove 411 along the direction defined by the limiting groove 48, thus preventing them from deviating, shaking or falling out of the moving groove 411, and ensuring the normal operation of the tent's top water-proof function.
[0036] Reference Figures 2-6 As shown: An auxiliary mechanism 5 is provided between the lifting block 42 and the support 2; the auxiliary mechanism 5 includes a first rotating block 51, a second rotating block 52 and an anti-collapse block 53; the first rotating block 51 is disposed on the side wall of the lifting block 42 and is fixedly connected to the lifting block 42, the second rotating block 52 is disposed on the upper end of the support 2 and is fixedly connected to the support 2; the anti-collapse block 53 is a telescopic structure, one end of the anti-collapse block 53 is rotatably connected to the first rotating block 51, and the other end of the anti-collapse block 53 is rotatably connected to the second rotating block 52.
[0037] When the lifting block 42 moves upward under the action of the lifting mechanism 4 to lift the tarpaulin 1, one end of the anti-collapse block 53 rotates around the first rotating block 51 and the other end rotates around the second rotating block 52. At the same time, the telescopic structure of the anti-collapse block 53 can automatically adjust its length according to the change in the distance between the lifting block 42 and the support 2, providing lateral support for the lifting block 42, preventing the tarpaulin 1 from collapsing due to external impact, maintaining the shape of the tent top, and thus ensuring the effective implementation of the tent's anti-water accumulation function. When the lifting block 42 falls downward, the anti-collapse block 53 also adapts to change its state according to the rotational connection between the components and its own telescopic characteristics, ensuring the reliability and durability of the entire tent structure.
[0038] Reference Figure 6 As shown: Several gaps are opened on the anti-collapse block 53.
[0039] Sunlight can enter the tent through the gaps.
[0040] Reference Figure 6 As shown: The anti-collapse block 53 is provided with a snap-fit base 531 at the rotatable connection part with the first rotating block 51 and the second rotating block 52, and the snap-fit base 531 snaps onto the snap-fit block 532; when the snap-fit block 532 is engaged with the snap-fit base 531, the anti-collapse block 53 is in a rotatable connection state with the first rotating block 51 and the second rotating block 52.
[0041] Align the locking block 532 with the locking base 531 and engage it. The locking base 531 and the locking block 532 fit tightly together, so that the anti-collapse block 53 can be stably rotated with the first rotating block 51 and the second rotating block 52. This ensures that the anti-collapse block 53 can rotate flexibly around the connection point during the lifting block 42's raising and lowering process. Based on the change in distance between the lifting block 42 and the bracket 2, it can adaptively adjust through its own telescopic structure to provide reliable lateral support for the lifting block 42. When it is necessary to disassemble the anti-collapse block 53, simply release the locking state between the locking block 532 and the locking base 531 to easily remove the anti-collapse block 53.
[0042] When setting up an advertising exhibition tent outdoors and encountering situations where water may accumulate, the lifting mechanism 4 needs to be activated to enable the anti-water accumulation function. Because existing lifting devices lack guidance and are prone to tilting, this tent base 41 and lifting block 42 are equipped with a guide mechanism 3. The base 41 has a moving groove 411, and the first moving block 43 and the second moving block 44 are symmetrically arranged in the groove. The two are threaded to the bidirectional threaded rod 47 in the groove. The bidirectional threaded rod 47, which has a limit hole 412 at the center of rotation, an internal rotating wheel 471, and a belt 472 on the outer wall, is driven by the friction of the belt 472 to rotate the rotating wheel 471 and the threaded rod, causing the two moving blocks to move towards each other along the groove. At the same time, because they are rotatably connected to the lifting block 42 by the first rotating rod 45 and the second rotating rod 46, the lifting block 42 is subjected to an upward force. With the help of the guide rod 32 inserted into the guide hole 31 at both ends of the base 41, vertical lifting is ensured. The lifting block 42 moves up to lift the tent fabric 1, changing its top shape to drain water and prevent water accumulation. When the tent is taken down, the bidirectional threaded rod 47 is rotated in the opposite direction, the moving blocks move in opposite directions, and the lifting block 42 moves down to return to its position. Furthermore, the limiting groove 48 on the inner wall of the moving slot 411 cooperates with the limiting block 49 of the moving block to ensure the stable linear movement of the moving block. The first rotating block 51 and the second rotating block 52 of the auxiliary mechanism 5 between the lifting block 42 and the support 2 are respectively fixed to the side wall of the lifting block 42 and the upper end of the support 2. The telescopic anti-collapse block 53 is rotatably connected to it at both ends. When lifting, the anti-collapse block 53 automatically extends and retracts according to the distance between the lifting block 42 and the support 2, and rotates around the connection point to provide lateral support. The same self-adaptive behavior is observed when falling. The gap of the anti-collapse block 53 allows light to pass through. Its connection with the rotating block is achieved by the locking base 531 and the locking block 532 engaging to achieve a stable rotational connection. During assembly, simply align and engage. When disassembling, release the engagement to easily remove the anti-collapse block 53. This ensures the stability of the tent structure and reliable operation in all aspects, and achieves the function of preventing water accumulation at the top.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
