Technical Field

[0001] The utility model relates to the technical field of reinforcement devices, in particular to a cargo packaging reinforcement device. Background Art

[0002] During cargo transportation, the corners of packaging boxes are prone to colliding, which can easily cause the boxes to break and damage the goods inside. Ensuring the stability of cargo packaging is crucial, as it directly impacts the integrity of the goods and the safety of transportation. Traditional methods of cargo packaging reinforcement often have many limitations. For example, foam padding, cardboard partitions, and wooden frames are not universally applicable and are difficult to adapt to the needs of packaging goods of different sizes. For irregularly shaped or sized goods, packaging must be customized according to the package and cargo dimensions, which increases equipment costs.

[0003] The stability of some existing reinforcement devices during transportation is also unsatisfactory. Once encountering common transportation conditions such as vibration and bumps, the reinforcement devices may become loose, displaced or fail, and cannot continue to effectively play their reinforcement and protection role. Therefore, a cargo packaging reinforcement device is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cargo packaging reinforcement device, which has the advantages of flexible adjustment and stable support, and solves the problems of poor adaptability and high production and customization costs of traditional reinforcement methods.

This adjustable design makes it suitable for packaging cartons of different sizes, enhancing the versatility and practicality of the device, and providing customized reinforcement solutions for cargoes of various specifications. The reinforcement strip adopts a right-angled triangular prism structure and is rotatably connected to the adjustment rod through a second rotating shaft. This design highlight enables the reinforcement strip to flexibly rotate and adjust its own angle when facing boxes of different sizes, ensuring that its side walls are tightly fitted with the edges of the inner wall of the packaging carton. This tight fit not only improves the stability of the support, but also more effectively disperses the pressure of the cargo on the carton wall, preventing the carton from being deformed or damaged due to local uneven force during transportation, thereby better protecting the integrity of the cargo.

[0015] 2. The utility model cooperates with the ratchet at the lower end of the adjustment knob and the pawl connected to the annular flange at the bottom of the connecting box through a pin shaft, and the pin shaft is sleeved with a spring and a limit plate, so that the pawl can interact with the ratchet under the action of the spring to achieve one-way locking of the adjustment rod. During transportation, even if it is subjected to external forces such as vibration and collision, the adjustment rod can only extend outward and cannot retract into the connecting box, effectively avoiding the device from losing its reinforcement and protection function due to unexpected circumstances, providing continuous and reliable support and protection for the goods, and ensuring that the goods are in a stable reinforcement state throughout the transportation process.

[0016] 3. The utility model greatly facilitates the combined use of multiple sets of reinforcement devices by providing a positioning groove on the lower end surface of the ratchet and a magnet on the top of the positioning groove in cooperation with an adjustment knob made of iron. When large goods or multiple goods need to be reinforced as a whole, multiple reinforcement devices can be quickly and firmly spliced ​​together. The adsorption effect of the magnet not only facilitates the combination operation, but also saves the space occupied by the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figures 1-9 , a cargo packaging reinforcement device, comprising an adjustment rod 1 and a reinforcement strip 2, further comprising a connection box 3 and an adjustment knob 4;

[0028] The reinforcement strip 2 is movably mounted on the lower end face of the adjusting rod 1, and a first slide groove 303 is provided on the side end face of the connecting box 3. The adjusting rod 1 is inserted into the first slide groove 303 and is slidingly connected to the connecting box 3. The adjusting knob 4 is installed in the center of the connecting box 3 and is rotatably connected thereto. A gear 403 is provided on the adjusting knob 4, and a hidden groove 101 is provided on the side face of the adjusting rod 1. A rack 102 cooperating with the gear 403 is provided in the hidden groove 101.

[0029] Furthermore, the reinforcement strip 2 is a right-angled triangular prism structure, and a second rotation shaft 201 is provided on the top of the reinforcement strip 2 . The reinforcement strip 2 and the adjustment rod 1 are rotationally connected via the second rotation shaft 201 .

[0030] The structure of the rotatably connected reinforcement strip 2 allows the reinforcement strip 2 to rotate and adjust its own angle when facing boxes of different sizes, so that the side walls of the reinforcement strip 2 fit closely with the edges of the inner wall of the packaging carton, thereby improving the stability of the support.

[0031] Furthermore, a first rotating shaft 402 is provided at the lower end of the adjusting knob 4, and a gear 403 is fixedly mounted on the first rotating shaft 402. A ratchet 401 is fixedly mounted on the bottom of the first rotating shaft 402, and a right-angled triangle-shaped ratchet is provided on the side of the ratchet 401. An annular flange 301 is provided at the bottom of the connecting box 3, and a second slide groove 3011 is provided on the side end face of the annular flange 301. The pin shaft 302 is installed in the second slide groove 3011 and is slidably connected to the annular flange 301. A pawl 3021 cooperating with the ratchet 401 is provided at the end of the pin shaft 302, and the end of the pawl 3021 is a right-angled triangle-shaped structure.

[0032] The pin shaft 302 can slide in the second slide groove 3011, thereby driving the pawl 3021 to approach the ratchet 401. When the pawl 3021 is inserted into the tooth gap of the ratchet 401, the ratchet 401 can only rotate in one direction, so that the adjusting rod 1 can only extend outward and cannot retract into the connecting box 3, thereby preventing the device from losing its reinforcement and protection function during transportation.

[0033] Furthermore, a spring 304 is sleeved on the pin shaft 302 , a limit plate is provided on the side end surface of the pin shaft 302 , and the pin shaft 302 is elastically slidably connected to the annular flange 301 via the spring 304 .

[0034] When the adjusting rod 1 extends outward, the ratchet teeth on the surface of the ratchet wheel 401 squeeze the pawl 3021, causing the pawl 3021 to slide outward. When it reaches the next ratchet gap, the pin 302 is automatically inserted into the ratchet gap of the ratchet wheel 401 under the reset action of the spring 304, thereby limiting the retraction of the adjusting rod 1.

[0035] Furthermore, a positioning groove 4011 is provided on the lower end surface of the ratchet 401 , and the diameter of the positioning groove 4011 is larger than the diameter of the adjusting knob 4 .

[0036] When multiple devices are matched, the adjusting knob 4 of the reinforcement device can be inserted into the positioning groove 4011 of the upper reinforcement device to combine multiple groups of reinforcement devices together.

[0037] Furthermore, a magnet 4012 is provided on the top of the positioning groove 4011, and the adjustment knob 4 is made of iron.

[0038] The magnet 4012 is used to adsorb the adjusting knob 4 of the lower reinforcement device to prevent the adjacent reinforcement devices from falling off during transportation, thereby affecting the support stability and improving the stability between the adjacent reinforcement devices.

[0039] Furthermore, the reinforcement strip 2 is made of nylon.

[0040] The reinforcement strip 2 made of nylon has sufficient structural strength and a certain degree of elasticity, and will not scratch the goods in the packaging box, thereby improving the protection effect.

[0041] When using this device, according to the shape and size of the packaging carton, pull out the adjusting rod 1, insert the reinforcement strip 2 into the diagonal corner of the packaging carton, and then turn the adjusting knob 4 to fine-tune the length of the adjusting rod 1. When turning the adjusting knob 4, the gear 403 on the knob cooperates with the rack 102 in the side groove 101 of the adjusting rod 1, so that the adjusting rod 1 slides outward and extends in the connecting box 3 until the side wall of the reinforcement strip 2 is tightly fitted with the edge of the inner wall of the packaging carton. During the extension process, the adjusting rod 1 is extended to an appropriate length according to the height and reinforcement requirements of the carton to ensure that the reinforcement strip 2 can provide effective support for the edges of the carton. When the adjusting rod 1 is extended to the appropriate position, the pawl 3021 cooperates closely with the ratchet 401 under the action of the spring 304, thereby limiting the retraction of the adjusting rod 1 so that it can only extend in one direction, avoiding the adjustment rod 1 from retracting due to vibration and other reasons during transportation and losing the reinforcement effect. When multiple reinforcement devices need to be used in combination, multiple groups of devices are inserted into different diagonals of the packaging box, and the adjustment knob 4 of the upper reinforcement device is aligned with the positioning groove 4011 on the lower end face of the ratchet 401 of the lower reinforcement device. During the alignment process, ensure that the adjustment knob 4 can be accurately inserted into the positioning groove 4011.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
