Description

Technical Field

[0001] This application relates to the field of camouflage tarpaulin technology, and more particularly to a camouflage tarpaulin storage roller with locking function. Background Technology

[0002] Camouflage tarpaulins are functional protective materials with environmental integration capabilities. Their function is to create visual or infrared concealment effects between the covered object and the surrounding environment, such as jungles, deserts, and snowfields, through special color coatings, pattern designs, or material properties. They are widely used in scenarios such as military equipment protection, field equipment covering, and temporary material storage. These tarpaulins are usually made of high-strength polyester fibers or PVC composite materials, and have properties such as tear resistance, water resistance, and UV resistance to adapt to complex outdoor environments. Due to the high concealment requirements of the usage scenarios, the size of camouflage tarpaulins is often customized according to the specifications of the covered object. During transportation and idle periods, they need to be organized with the help of storage devices to avoid material wear or pattern damage. Storage rollers are currently the mainstream organizing tools.

[0003] Currently, storage rollers are manually rotated to wind and gather unfolded camouflage tarpaulins, reducing storage volume and facilitating handling. However, traditional storage rollers lack a locking structure and rely solely on the friction of the roller shaft to maintain the winding state. When the storage roller is placed at an angle or subjected to vibration or collision during handling, the roller shaft is prone to reverse rotation due to external forces, causing the neatly wound camouflage tarpaulin to loosen and slip off. Furthermore, in emergency scenarios such as field operations, the tarpaulin's disarray will prolong the time required for secondary unfolding, reducing operational efficiency and failing to meet the requirements for storage stability and convenience. Therefore, to solve these problems, we provide a camouflage tarpaulin storage roller with a locking function. Summary of the Invention

[0004] The purpose of this utility model is to provide a camouflage tarpaulin storage roller with a locking function, so as to solve the problem mentioned in the background art that the current traditional storage rollers lack a locking structure and rely only on the friction of the roller shaft itself to maintain the winding state. When the storage roller is placed at an angle or is subjected to vibration or collision during transportation, the roller shaft is prone to reverse rotation due to external force, resulting in the neatly wound camouflage tarpaulin becoming loose and slipping off.

[0005] The embodiments of this application adopt the following technical solutions: A camouflage tarpaulin storage roller with locking function includes a storage cover, a base fixedly installed at the bottom of the storage cover, a bearing ring fixedly embedded on the upper surface of the base, a storage roller body fixedly connected to the inner ring of the bearing ring, a camouflage tarpaulin fixedly connected to one side of the storage roller body, an elastic locking element fixedly embedded on one side of the storage cover, a threaded fixing seat fixedly connected to the outer surface of the storage cover, a threaded cover plate threadedly connected to the inner ring of the threaded fixing seat, a circular cover fixedly connected to the upper surface of the threaded cover plate, a threaded drive rod disposed inside the circular cover, a threaded locking seat threadedly connected to the outer surface of the threaded drive rod, an annular fixing seat fixedly connected to the top of the storage roller body, and the bottom end of the threaded locking seat extending into the interior of the annular fixing seat.

[0006] Preferably, the inner ring of the circular cover is fixedly connected to a limiting slide, the inner wall of the limiting slide is slidably connected to a limiting slider, and one side of the limiting slider is fixedly connected to the outer surface of the threaded locking seat.

[0007] Preferably, a bearing ring is fixedly embedded on the upper surface of the circular cover, the outer surface of the top end of the threaded transmission rod is fixedly connected to the inner ring of the bearing ring, and a rotating handwheel is fixedly installed on the top end of the threaded transmission rod.

[0008] Preferably, a circular fixing pad is fixedly connected to the inner bottom wall of the annular fixing seat, and the outer surface of the bottom end of the threaded locking seat is in close contact with the upper surface of the circular fixing pad.

[0009] Preferably, the elastic locking component includes a sliding cover fixedly embedded on the outer surface of the storage cover, a spring fixedly connected to the inner wall of the sliding cover, an arc-shaped sliding plate fixedly connected to one end of the spring, an arc-shaped fixing pad fixedly connected to one side of the arc-shaped sliding plate, a connecting slide plate fixedly connected to one side of the arc-shaped sliding plate, a limit pull plate fixedly connected to one side of the connecting slide plate, and two buffer pads fixedly connected to one side of the sliding cover, with one side of each of the two buffer pads contacting one side of the limit pull plate.

[0010] Preferably, one side of the storage cover has a roll-up through hole, the camouflage tarpaulin is located inside the roll-up through hole, the upper surface of the base has multiple mounting holes, and a portable handle is fixedly connected to the outer surface of the storage cover.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This camouflage tarpaulin storage roller with locking function uses a spring to push an arc-shaped fixing pad into close contact with the camouflage tarpaulin on the surface of the storage roller. Friction initially limits the tarpaulin's movement, preventing it from becoming loose. Additionally, a threaded transmission rod moves a threaded locking seat downwards until it comes into close contact with the circular fixing pad inside the annular fixing seat. This mechanically secures the storage roller, preventing reverse rotation even during significant impacts or prolonged storage. This solves the problem of tarpaulin slippage and scattering caused by the lack of locking in traditional storage rollers. To unlock, simply pull the limiting plate; the operation is convenient and does not affect secondary unfolding efficiency. In emergency field operations, this ensures rapid tarpaulin unfolding, shortens preparation time, improves operational efficiency, and meets the needs for storage stability and emergency use.

[0012] Second, the camouflage tarpaulin storage roller with locking function, through the connection between the storage roller body and the inner ring of the bearing ring, utilizes the characteristics of the bearing to reduce the frictional resistance when the storage roller body rotates, making it easier to manually drive the storage roller body. Through the winding through hole on the side of the storage cover, the camouflage tarpaulin can be allowed to enter the device, avoiding tarpaulin deviation and wrinkles during the winding process, ensuring neat winding, and reducing the difficulty of subsequent processing.

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0016] As attached Figures 1-5 The camouflage tarpaulin storage roller with locking function shown includes a storage cover 1, a base 3 fixedly installed at the bottom of the storage cover 1, a bearing ring 4 fixedly embedded on the upper surface of the base 3, a storage roller body 5 fixedly connected to the inner ring of the bearing ring 4, a camouflage tarpaulin 2 fixedly connected to one side of the storage roller body 5, an elastic locking element 9 fixedly embedded on one side of the storage cover 1, a threaded fixing seat 17 fixedly connected to the outer surface of the storage cover 1, a threaded cover plate 8 threadedly connected to the inner ring of the threaded fixing seat 17, a circular cover 11 fixedly connected to the upper surface of the threaded cover plate 8, a threaded transmission rod 7 provided inside the circular cover 11, a threaded locking seat 12 threadedly connected to the outer surface of the threaded transmission rod 7, an annular fixing seat 10 fixedly connected to the top of the storage roller body 5, and the bottom end of the threaded locking seat 12 extending into the interior of the annular fixing seat 10.

[0017] As can be seen from the above description, the present invention has the following beneficial effects, wherein: the bearing ring 13 can reduce the frictional resistance when the threaded transmission rod 7 rotates, and the threaded transmission rod 7 drives the threaded locking seat 12 to move down until it is in close contact with the circular fixing pad 18 in the annular fixing seat 10. The storage roller 5 can be completely fixed by mechanical limiting, and even if it is subjected to a large collision during transportation or stored for a long time, it can prevent the storage roller 5 from rotating in the opposite direction. Example 2

[0018] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: In this embodiment, the inner ring of the circular cover 11 is fixedly connected to a limiting slide 14, and the inner wall of the limiting slide 14 is slidably connected to a limiting slider 15. One side of the limiting slider 15 is fixedly connected to the outer surface of the threaded locking seat 12. A bearing ring 13 is fixedly embedded on the upper surface of the circular cover 11. The outer surface of the top end of the threaded transmission rod 7 is fixedly connected to the inner ring of the bearing ring 13. A rotating handwheel 16 is fixedly installed on the top end of the threaded transmission rod 7. A circular fixing pad 18 is fixedly connected to the inner bottom wall of the annular fixing seat 10. The outer surface of the bottom end of the threaded locking seat 12 is in close contact with the upper surface of the circular fixing pad 18. A winding through hole 6 is opened on one side of the storage cover 1. The camouflage tarpaulin 2 is located inside the winding through hole 6. Multiple mounting holes 20 are opened on the upper surface of the base 3. A portable handle 19 is fixedly connected to the outer surface of the storage cover 1. Furthermore, the limiting slide 14 fixed by the inner ring of the circular cover 11 and the surface of the threaded locking seat 12 are limited. The slider 15, in conjunction with the threaded locking seat 12, limits the movement direction of the threaded locking seat 12. When the threaded transmission rod 7 rotates and drives the threaded locking seat 12 to rise or fall, the limiting slider 15 will slide along the inner wall of the limiting slide seat 14 to prevent the threaded locking seat 12 from rotating synchronously with the threaded transmission rod 7, ensuring that it always moves vertically. At the same time, the winding through hole 6 can guide the camouflage tarpaulin into the device in an orderly manner, ensuring that the tarpaulin 2 does not deviate during the winding process and ensuring the neatness of the winding. By rotating the handwheel 16, it is easier to manually rotate the threaded transmission rod 7 and quickly complete the lifting and lowering operation of the threaded locking seat 12. The circular fixing pad 18 on the inner bottom wall of the annular fixing seat 10 can increase the contact area between the bottom end of the threaded locking seat 12 and the annular fixing seat 10, improve the locking stability, and avoid wear on the contact surface due to long-term use. In addition, the mounting hole 20 on the base 3 facilitates the fixing of the device, and the portable handle 19 on the outer surface of the storage cover 1 facilitates transportation and improves the practicality of the device.

[0019] In this embodiment, the elastic locking member 9 includes a sliding cover 91 fixedly embedded on the outer surface of the storage cover 1, a spring 92 fixedly connected to the inner wall of the sliding cover 91, an arc-shaped sliding plate 93 fixedly connected to one end of the spring 92, an arc-shaped fixing pad 94 fixedly connected to one side of the arc-shaped sliding plate 93, a connecting slide plate 95 fixedly connected to one side of the arc-shaped sliding plate 93, a limiting pull plate 96 fixedly connected to one side of the connecting slide plate 95, and two buffer pads 97 fixedly connected to one side of the sliding cover 91. One side of each buffer pad 97 contacts one side of the limiting pull plate 96. In one step, the spring 92 on the inner wall of the sliding cover 91 provides elastic force, which can push the arc-shaped sliding plate 93 to drive the arc-shaped fixing pad 94 to make close contact with the receiving roller 5. The friction force is used to achieve the initial locking of the receiving roller 5, preventing the receiving roller 5 from rotating slightly after winding. When unlocking, the limit plate 96 is pulled, and the connecting slide plate 95 drives the arc-shaped sliding plate 93 to compress the spring 92, which can separate the arc-shaped fixing pad 94 from the receiving roller 5. The buffer pad 97 can play a buffering role when the limit plate 96 is reset, avoiding damage to the parts by collision and extending the service life of the elastic locking part 9.

[0020] Working principle: When the camouflage tarpaulin storage roller with locking function is used, first wrap or fix one end of the camouflage tarpaulin to the camouflage tarpaulin 2. Then, the storage roller body 5 is manually rotated to achieve the winding action. Since the outer ring of the storage roller body 5 is connected to the inner ring of the bearing ring 4, the bearing ring 4 can reduce the frictional resistance when the storage roller body 5 rotates, making it easier to manually drive the storage roller body 5 to rotate. During the rotation of the storage roller body 5, the camouflage tarpaulin 2 will rotate synchronously, and the unfolded camouflage tarpaulin will be gradually wrapped around the surface of the camouflage tarpaulin 2. At this time, the camouflage tarpaulin will enter the device through the winding through hole 6 opened on one side of the storage cover 1, realizing orderly winding.

[0021] Once the camouflage tarpaulin is rolled up to the desired position, the storage roller 5 is fixed by a double-locking structure to prevent it from rotating in the opposite direction. The first locking is achieved by the elastic locking element 9. The spring 92 generates an elastic thrust on the arc-shaped sliding plate 93, pushing the arc-shaped fixing pad 94 on one side of the arc-shaped sliding plate 93 into close contact with the camouflage tarpaulin 2 on the surface of the storage roller 5. This friction initially restricts the rotation of the storage roller 5. To release this lock, pull the limiting plate 96, which, through the connecting slide plate 95, causes the arc-shaped sliding plate 93 to compress the spring 92, thus releasing the arc-shaped fixing pad. 94 can be separated from the storage roller 5. During the second locking, rotating the handwheel 16 at the top of the circular cover 11 can drive the threaded transmission rod 7 to rotate. When the threaded transmission rod 7 rotates, its threaded transmission threaded locking seat 12 will move vertically downward along the limiting slider 15 in the limiting slide 14 until the bottom end of the threaded locking seat 12 is in close contact with the circular fixing pad 18 on the inner bottom wall of the annular fixing seat 10. The storage roller 5 is fixed by mechanical limiting to prevent it from rotating in the opposite direction due to vibration or collision, avoid the camouflage tarpaulin from becoming loose, and meet the needs of quick access in emergency scenarios.
