Description

Technical Field

[0001] This utility model relates to the field of containers, and more specifically, to a container with a side panel opening and closing system. Background Technology

[0002] In traditional container applications, the vast majority of containers have their import / export points located at the ends. However, when containers are converted for commercial use, the limitations of end-entry / export points become apparent. The relatively narrow space not only restricts the display area and arrangement of goods, making it difficult to attract customer attention, but also easily causes congestion during peak hours, hindering smooth customer flow and efficient goods handling, significantly impacting the shop's operational efficiency.

[0003] In recent years, to improve this situation, some shipping containers used as shops have attempted to place the entrances and exits on the sides, using telescopic drive devices to connect the overall structure with the openable side panels. While this design has solved some of the problems with end entrances and exits, the high cost of purchasing, installing, and maintaining the telescopic drive devices, along with their complex structure which increases the difficulty and cost of manufacturing, has greatly limited its practical application. Therefore, the market urgently needs a container side panel opening and closing system that can meet the needs of side entrances and exits, has lower usage and manufacturing costs, and is easy to operate, stable, and reliable, in order to improve the practicality and competitiveness of containers in the commercial sector and meet the increasingly diverse needs of business operations.

[0004] How to invent a container with a side panel opening and closing system to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a container with a side panel opening and closing system, which aims to improve the existing containers used as shops by setting the entrance and exit on the side and using a telescopic drive device to connect the overall structure with the openable side panel. Although this design solves some of the problems of the end entrance and exit to a certain extent, the procurement, installation and maintenance costs of the telescopic drive device are high, and its complex structure also increases the difficulty and cost of manufacturing process.

[0006] This utility model is implemented as follows: a container with a side panel opening and closing system includes a container body, an opening and closing side panel is rotatably connected to the front side of the container body, a connecting part is provided on the side surface of the opening and closing side panel away from the container body, the connecting part is detachably connected to one end of a traction rope, the other end of the traction rope is connected to a winding assembly, and four sets of support and guide mechanisms for limiting the traction rope are respectively provided on both sides of the top of the container body.

[0007] In a preferred embodiment of this utility model, a hanging ring is rotatably mounted on the connecting part, and a hook is provided at one end of the traction rope, the hook being connected to the hanging ring.

[0008] In a preferred embodiment of this utility model, one end of the hook is rotatably connected to one end of the traction rope.

[0009] In a preferred embodiment of this utility model, the winding assembly includes a mounting part, which is fixedly installed on the bottom of the rear surface of the container body. An outer shell is integrally formed above the mounting part. One end of the winding shaft is rotatably mounted on the inner wall of one end of the outer shell. An extension hole is provided through the top outer wall of the outer shell. One end of the traction rope extends from the extension hole into the interior of the outer shell and is wound around the winding shaft, with one end of the rope being fixedly connected to the outer wall of the winding shaft. The other end of the winding shaft extends to the outside of the outer shell and is connected to a self-locking limiting mechanism.

[0010] In a preferred embodiment of this utility model, the self-locking limiting mechanism includes a worm wheel fixedly sleeved on the other end of the housing. The worm wheel is meshed with a worm on one side. The worm is rotatably mounted between two oppositely arranged mounting plates, and one end of the worm extends through one mounting plate and is fixedly connected to a crank handle.

[0011] In a preferred embodiment of this utility model, the four support and guide mechanisms are respectively arranged on both sides of the top surface of the container body and on the top of the front and rear sides of the container body, and are located on the same longitudinal plane.

[0012] In a preferred embodiment of this utility model, each of the supporting and guiding mechanisms includes a U-shaped mounting base, which is fixedly mounted on the corresponding side surface of the container body. A guide limiting wheel with a limiting groove on the outer wall is rotatably mounted between the inner walls on both sides of the U-shaped mounting base.

[0013] In a preferred embodiment of this utility model, the two ends of the side surface of the opening and closing side plate facing the container body are respectively rotatably connected to one end of a corresponding hydraulic damper, and the other end of each hydraulic damper is rotatably connected to the inner wall of the corresponding end of the container body.

[0014] The beneficial effects of this utility model are as follows: The container with a side panel opening and closing system obtained through the above design achieves efficient side panel opening and closing by utilizing relatively low-cost components such as traction ropes, winding assemblies, and support and guiding mechanisms to form a simple mechanical structure. This reduces reliance on expensive telescopic drive devices, significantly lowering costs in all aspects from equipment procurement and installation to subsequent maintenance, saving businesses substantial funds and improving the economic efficiency of commercial operations.

Detailed Implementation

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a container with a side panel opening and closing system, including a container body 1, an opening and closing side panel 2 rotatably connected to the front side of the container body 1, a connecting part 201 provided on the side surface of the opening and closing side panel 2 away from the container body 1, the connecting part 201 being detachably connected to one end of a traction rope 3, the other end of the traction rope 3 being connected to a winding assembly 4, and four sets of support and guide mechanisms 5 for limiting the traction rope 3 being provided on both sides of the top of the container body 1.

[0024] Please see Figure 2 and Figure 3 A hanging ring 202 is rotatably mounted on the connecting part 201, and a hook 301 is provided at one end of the traction rope 3. The hook 301 is connected to the hanging ring 202.

[0025] A hanging ring 202 is installed on the connecting part 201. The hanging ring can rotate flexibly around the axis, and the hook 301 at one end of the traction rope 3 is engaged with the hanging ring 202. When the opening and closing side plate 2 rotates, the hanging ring 202 rotates accordingly, ensuring that the traction rope 3 can always effectively transmit tension without jamming or damage to the connection due to changes in the side plate angle. This improves the reliability and durability of the connection between the traction rope 3 and the opening and closing side plate 2, reducing maintenance costs and downtime caused by damage to the connecting parts. At the same time, the flexible connection method also makes the opening and closing action of the side plate smoother, further enhancing the convenience of shop use.

[0026] Furthermore, one end of hook 301 is rotatably connected to one end of traction rope 3.

[0027] One end of hook 301 is rotatably connected to one end of traction rope 3, for example, by means of a pin connection, allowing hook 301 to rotate relative to traction rope 3 within a certain range. When the direction of tension in traction rope 3 changes during pulling, hook 301 can automatically adjust its angle to maintain good fit with hanging ring 202. This further optimizes the connection performance between traction rope 3 and opening / closing side panel 2, reduces the risk of connection failure due to changes in the direction of tension, improves the stability and reliability of the entire side panel opening / closing system, and ensures smooth operation of side panel opening and closing in daily business operations.

[0028] Please see Figure 5 The winding assembly 4 includes a mounting part 401, which is fixedly mounted on the bottom of the rear surface of the container body 1. A housing 402 is integrally provided above the mounting part 401. One end of the winding shaft 403 is rotatably mounted on the inner wall of one end of the housing 402. An extension hole 404 is provided through the top outer wall of the housing 402. One end of the traction rope 3 extends from the extension hole 404 into the interior of the housing 402 and is wound around the winding shaft 403, with one end fixedly connected to the outer wall of the winding shaft 403. The other end of the winding shaft 403 extends to the outside of the housing 402 and is connected to the self-locking limiting mechanism.

[0029] The mounting part 401 is securely fixed to the bottom of the rear surface of the container body 1, providing stable support for the winding assembly. The outer shell 402 is integrally mounted above the mounting part 401, forming a space to protect and accommodate the winding shaft 403. One end of the winding shaft 403 is rotatably mounted on the inner wall of one end of the outer shell 402. One end of the traction rope 3 enters the interior through the extension hole 404 at the top of the outer shell 402, winds around the winding shaft 403, and is fixedly connected to the outer wall of the winding shaft 403, ensuring that the traction rope 3 can be wound up and down when the winding shaft 403 rotates. This makes the winding and unwinding operation of the traction rope 3 more orderly and efficient, and allows for precise control of the opening and closing degree of the side panel 2. At the same time, the outer shell 402 protects the internal components from the influence of the external environment, extends the service life of the winding assembly 4, and provides a guarantee for the long-term stable operation of the shop.

[0030] Furthermore, the self-locking limiting mechanism includes a worm gear 405 fixedly sleeved on the other end of the housing 402. The worm gear 405 is meshed with a worm 406 on one side. The worm 406 is rotatably mounted between two oppositely arranged mounting plates 407, and one end of the worm 406 extends through one side mounting plate 407 and is fixedly connected to a crank handle 408.

[0031] The worm gear 405 is fixedly sleeved on the other end of the housing 402 and meshes with a worm 406 on one side. The worm 406 is rotatably mounted between two opposing mounting plates 407, with one end extending through one mounting plate 407 and fixedly connected to a crank 408. Turning the crank 408 drives the worm 406 to rotate, which in turn drives the worm gear 405 to rotate. When the worm 406 stops rotating, due to the self-locking characteristics of the worm gear 405 and worm 406, the winding shaft 403 is locked and cannot rotate freely, thus fixing the traction rope 3 and maintaining the position of the open / closed side plate 2. During the unfolding of the side plate or when the side plate is closed, the self-locking limiting mechanism can effectively prevent the side plate from opening or closing accidentally. At the same time, this simple and reliable self-locking method is easy to operate, does not require additional complex locking devices, and reduces costs and operating difficulty.

[0032] Please see Figure 2 and Figure 4 The four support and guide mechanisms 5 are respectively set on the top surface of the container body 1 on both sides and the top of the front and rear surfaces of the container body 1, and are located on the same longitudinal plane.

[0033] Four support and guide mechanisms 5 are respectively installed on both sides of the top surface of the container body 1 and on the top of the front and rear sides of the container body 1, all located on the same longitudinal plane. This layout forms a continuous channel. The traction rope 3 starts from the rear side of the container body 1 and passes through these four sets of support and guide mechanisms 5 in sequence. Each support and guide mechanism 5 supports and limits the traction rope 3, allowing it to extend along a predetermined trajectory to the front side of the container body 1 and connect with the opening and closing side panel 2. This effectively prevents the traction rope 3 from getting tangled or rubbing against other parts of the container body 1 during the pulling process, ensuring the efficient operation of the system. The optimized layout of the support and guide mechanisms 5 improves the working stability of the traction rope 3, thereby enhancing the reliability and durability of the entire side panel opening and closing system. The stable operation of the traction rope 3 reduces side panel opening and closing failures caused by rope problems, lowers maintenance frequency and costs, provides strong support for the continuous and normal operation of the shop, and also enhances the safety and comfort of customers in the shop, avoiding potential safety hazards caused by equipment failure.

[0034] Furthermore, each support guide mechanism 5 includes a U-shaped mounting base 501, which is fixedly mounted on the corresponding side surface of the container body 1. Guide limit wheels 502 with limit grooves on the outer wall are rotatably installed between the inner walls on both sides of the U-shaped mounting base 501.

[0035] The U-shaped mounting base 501 is firmly fixed to the corresponding side surface of the container body 1. Guide limit wheels 502 are rotatably mounted between the inner walls of the base and the outer wall of the guide limit wheels 502 have a limiting groove that fits tightly with the traction rope 3. When the traction rope 3 is pulled or released by the winding assembly 4, it slides within the limiting groove of the guide limit wheel 502. The guide limit wheel 502 can rotate flexibly with the movement of the traction rope 3, effectively limiting the lateral displacement of the traction rope 3 and ensuring that it pulls the side panel 2 in the correct direction. It also greatly reduces the friction between the traction rope 3 and the support guide mechanism 5 through rolling friction, reducing energy loss and component wear, and improving the overall efficiency and lifespan of the system. This allows the support guide mechanism 5 to guide the movement of the traction rope 3 with high precision, greatly improving the accuracy and stability of the side panel opening and closing, and reducing abnormal side panel opening and closing caused by the traction rope 3 deviating from the predetermined trajectory. At the same time, the reduced friction and wear not only extend the replacement cycle of the traction rope 3 but also reduce operating costs.

[0036] Furthermore, each end of a corresponding hydraulic damper 6 is rotatably connected to one end of the side surface of the opening and closing side panel 2 facing the container body 1, and the other end of each hydraulic damper 6 is rotatably connected to the inner wall of the corresponding end of the container body 1.

[0037] Each end of the side panel 2 facing the container body 1 is rotatably connected to a corresponding hydraulic damper 6, and the other end of each hydraulic damper 6 is rotatably connected to the corresponding inner wall of the container body 1. When the side panel 2 opens or closes, the hydraulic damper 6 generates a corresponding damping force according to the movement speed of the side panel, controlling the opening and closing speed of the side panel and avoiding danger caused by excessive speed. When the side panel is closed, the hydraulic damper 6 also buffers the impact force of the side panel, preventing the side panel from colliding violently with the container body 1 and protecting the safety of equipment and goods. The addition of the hydraulic damper 6 significantly improves the safety and comfort of the side panel opening and closing system. In shop usage scenarios, especially in situations with frequent personnel entry and exit, it can effectively avoid accidental injuries caused by improper opening and closing of the side panel. At the same time, buffering the impact force also reduces the risk of equipment damage, lowers maintenance costs, and improves the economic efficiency of shop operations.

[0038] Working principle: When the opening and closing side panel 2 needs to be opened, first operate the crank 408 of the winding assembly 4 to rotate the worm gear 406, which in turn drives the worm wheel 405 to rotate. At this time, the winding shaft 403 starts to rotate, gradually releasing the traction rope 3 wound on it. The traction rope 3 starts from the rear of the container body 1, follows the predetermined trajectory formed by the four sets of support and guide mechanisms 5, passes through the limiting groove of the guide limiting wheel 502, and moves steadily towards the front of the container body 1. Since the hook 301 is rotatably connected to one end of the traction rope 3, and the hook 301 is hooked to the hanging ring 202 on the opening and closing side panel 2, as the traction rope 3 is released, its tension will act on the opening and closing side panel 2, causing the opening and closing side panel 2 to slowly rotate outward around the rotatable connection point with the front of the container body 1 and open. During this process, the hydraulic damper 6 generates damping force according to the movement speed of the opening and closing side panel 2, controlling its opening and closing speed to avoid danger caused by excessive speed. At the same time, the guide limit wheel 502 rotates with the movement of the traction rope 3, ensuring that the traction rope 3 is always pulled in the correct direction, ensuring that the side panel opens smoothly until the required opening degree is reached. After the opening and closing side panel 2 is unfolded, the hook 301 and the hanging ring 202 can be disconnected and the traction rope 3 can be retracted to avoid occupying the entrance and exit space of the container body 1. When it is time to close the opening and closing side panel 2, the rewinding assembly 4 is operated in reverse, causing the rewinding shaft 403 to rewind the traction rope 3. The traction rope 3 pulls the opening and closing side panel 2 closer to the container body 1. Similarly, under the action of the hydraulic damper 6, the opening and closing side panel 2 will close slowly to avoid violent collision with the container body 1. Finally, after it is completely closed, the self-locking characteristic of the worm gear locks the rewinding shaft 403 to prevent the side panel from moving accidentally, completing a complete side panel opening and closing operation.

[0039] It should be noted that the specific model and specifications of the hydraulic damper 6 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The principle of the hydraulic damper 6 is clear to those skilled in the art and will not be described in detail here.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
