Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, and particularly relates to a fixing device for a logistics box. Background Technique

[0002] In the Chinese utility model patent application No.: CN202222217316.9, there is disclosed an anti-slip fixing structure for a logistics box. The structure includes a box body, and a shock-absorbing component is arranged inside the box body. The shock-absorbing component includes a bearing plate arranged in the inner cavity of the box body. The side edges around the bearing plate are in contact with the inner wall of the box body. Anti-slip bumps are evenly distributed on the top of the bearing plate, and the cross-sectional shape of the anti-slip bumps is semi-circular. For this anti-slip fixing structure of the logistics box, by setting anti-slip strips to play an anti-slip role, it is avoided that the displacement of the box body is caused by the shaking of the vehicle body during transportation. However, when the vehicle is driving on a rough road section, the vehicle body will not only shake left and right but also vibrate up and down. When the logistics box vibrates up and down, the anti-slip strips in the existing anti-slip fixing structure of the logistics box may not be able to play an anti-slip role. In addition, it may also cause the stacked logistics boxes to collapse, thereby resulting in damage to the goods.

[0003] Therefore, it is very necessary to propose a fixing device for a logistics box to solve the above problems. Content of the Utility Model

[0004] Technical problems to be solved: The purpose of the utility model is to provide a fixing device for a logistics box to solve the problems raised in the above background technique, that is, when the vehicle is driving on a rough road section, the vehicle body will not only shake left and right but also vibrate up and down. When the logistics box vibrates up and down, the anti-slip strips in the existing anti-slip fixing structure of the logistics box may not be able to play an anti-slip role. In addition, it may also cause the stacked logistics boxes to collapse, thereby resulting in damage to the goods.

[0005] Technical solution: To achieve the above objectives, the present utility model is realized through the following technical solutions: A fixing device for a logistics box includes a fixing plate fixedly installed on the floor of the logistics vehicle compartment, and also includes a connecting device. The fixing plate, the logistics box, and two adjacent logistics boxes above and below are all fixed together through the connecting device. The connecting device includes an installation hole opened at the top of the fixing plate, second connecting rings and first connecting rings fixedly installed at the upper and lower ends of the logistics box, a plugging mechanism arranged inside the first connecting ring, and a clamping component arranged inside the second connecting ring and the installation hole, and the first connecting ring, the second connecting ring, and the installation hole are concentrically arranged; the plugging mechanism includes a driving component and a plugging component. The plugging component includes a lower connecting rod slidably sleeved vertically inside the first connecting ring, and also includes a lower stop platform, a tension spring, an upper clamping block, and a lower clamping block arranged on the lower connecting rod below the first connecting ring from top to bottom in sequence; the lower stop platform and the lower clamping block are fixedly connected to the lower connecting rod, the upper clamping block is slidably connected to the lower connecting rod, both ends of the tension spring are fixedly connected to the lower stop platform and the upper clamping block respectively, and the driving component is in transmission connection with the lower connecting rod and drives the lower connecting rod to move up and down; the clamping component includes a locking block slidably installed radially inside the second connecting ring and the installation hole, a spring is fixedly installed at one end of the locking block away from the lower connecting rod, and inclined surfaces inclined downward are opened on the adjacent sides of the top of the upper clamping block and the locking block, and an inclined surface inclined upward is opened on one side of the bottom of the lower clamping block close to the locking block.

[0007] Preferably, a transition step and a V-shaped groove are recessed upward on one side of the lower end of the driving ring. One side of the V-shaped groove is butted against the transition step, and the other side is butted against the lower end surface of the driving ring. The maximum distance between the transition step and the lower end surface of the driving ring is a, and the maximum distance between the V-shaped groove and the lower end surface of the driving ring is b, where a < b. The top end of the connecting rod is fixedly connected to the upper connecting rod, a ball is fixedly installed on one side of the bottom, and a top spring is fixedly installed at the lower end.

[0008] Preferably, the upper clamping block and the lower clamping block are two symmetrically arranged frustums of a cone.

[0011] Beneficial effects: Compared with the prior art, the present utility model provides a fixing device for a logistics box. The fixing device for the logistics box has a unique structure and is convenient to use. By rotating the rotating handle clockwise, the upper connecting rod is driven to rotate, and then the connecting rod and the ball are driven to move in the driving ring. When the ball moves to the transition step, the thrust of the top spring causes the lower connecting rod to move downward, and at the same time, the tension spring is compressed. The inclined surface of the lower clamping block contacts the inclined surface of the locking block, and the locking block is squeezed into the installation cavity. When the lower clamping block passes over the locking block, the locking block is inserted between the upper clamping block and the lower clamping block under the elastic force of the spring to achieve fixation; when unlocking is required, just rotate the rotating handle clockwise again to make the ball enter the V-shaped groove, and the top spring pushes the lower connecting rod downward again. At this time, the upper clamping block contacts the locking block, compresses the tension spring, until the upper clamping block squeezes the locking block into the installation cavity again, and then the upper connecting rod drives the connecting rod to move upward, and the upper clamping block and the lower clamping block move upward at the same time, releasing the locking of the locking block, thereby unlocking the logistics box.

[0012] By evenly arranging a plurality of connecting devices on the periphery of the logistics box, not only the connection stability between the logistics box and the fixed plate is significantly improved, preventing shaking when driving on rough roads, but also the design of the plugging mechanism makes the fixing and unlocking processes of the logistics box simple and fast, which can be completed by rotating the handle, improving the loading and unloading efficiency.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1: Embodiment 1 of the present invention provides a fixing device for a logistics box, which is directly improved on the existing anti-slip fixing structure for a logistics box, with a unique structure. Please refer to Figures 1-6 As shown in the figure, it includes a fixed plate 1 fixedly installed on the floor of the logistics vehicle carriage, and also includes a connecting device. The fixed plate 1, the logistics box 2, and two adjacent logistics boxes 2 above and below are all fixed together through the connecting device. The connecting device includes an installation hole opened at the top of the fixed plate 1, second connecting rings 16 and first connecting rings 3 fixedly installed at the upper and lower ends of the logistics box 2, a plugging mechanism arranged in the first connecting ring 3, and a clamping component arranged in the second connecting ring 16 and the installation hole, and the first connecting ring 3, the second connecting ring 16, and the installation hole are concentrically arranged.

[0022] A plurality of connecting devices are installed on the logistics box 2, and the plurality of connecting devices are evenly arranged on the periphery of the logistics box 2. By arranging a plurality of connecting devices, the connection stability between the fixed plate 1, the logistics box 2, and two adjacent logistics boxes 2 above and below is increased; the plugging mechanism includes a driving component and a plugging component. The plugging component includes a lower connecting rod 5 slidably sleeved in the first connecting ring 3 in the vertical direction, and also includes a lower retaining platform 12, a tension spring 13, an upper clamping block 14, and a lower clamping block 15 sequentially arranged on the lower connecting rod 5 below the first connecting ring 3 from top to bottom. There are various installation methods for the lower connecting rod 5. For example, a plurality of vertically arranged chutes are evenly opened on the inner wall of the lower connecting rod 5, and sliders are slidably installed in the chutes, and the sliders are fixedly connected to the lower connecting rod 5.

[0023] The lower retaining platform 12 and the lower clamping block 15 are fixedly connected to the lower connecting rod 5. The upper clamping block 14 is slidably connected to the lower connecting rod 5. The two ends of the tension spring 13 are respectively fixedly connected to the lower retaining platform 12 and the upper clamping block 14. And the driving assembly is in transmission connection with the lower connecting rod 5 and drives the lower connecting rod 5 to move up and down. In the initial state, the upper clamping block 14 is suspended above the lower clamping block 15 through the tension spring 13, and there is a gap for the locking block 18 to be inserted between the upper clamping block 14 and the lower clamping block 15. The driving assembly includes an upper connecting rod 4 rotatably sleeved in the first connecting ring 3. An upper retaining platform 10 is fixedly installed on the upper connecting rod 4 above the first connecting ring 3. A rotating handle 11 is fixedly installed at the top of the upper connecting rod 4. A blind hole is opened at the top of the lower connecting rod 5. A driving ring 6 is fixedly sleeved in the blind hole. A connecting rod 7 is movably sleeved in the driving ring 6. There are various installation methods for the upper connecting rod 4. For example, the upper connecting rod 4 is rotatably installed in the first connecting ring 3 through a bearing.

[0024] One side of the lower end of the driving ring 6 is recessed upward to form a transition step 601 and a V-shaped groove 602. One side of the V-shaped groove 602 is butted against the transition step 601, and the other side is butted against the lower end face of the driving ring 6. And the maximum distance between the transition step 601 and the lower end face of the driving ring 6 is a, and the maximum distance between the V-shaped groove 602 and the lower end face of the driving ring 6 is b, where a < b. The top end of the connecting rod 7 is fixedly connected to the upper connecting rod 4, a ball 8 is fixedly installed on one side of the bottom, and a top spring 9 is fixedly installed at the lower end. In the initial state, the top spring 9 pushes the connecting rod 7 so that the ball 8 abuts against the lower end face of the driving ring 6. The clamping assembly includes a locking block 18 slidably installed along the radial direction in the second connecting ring 16 and the installation hole. One end of the locking block 18 away from the lower connecting rod 5 is fixedly installed with a spring 19. Inclined downward slopes are provided on the adjacent sides of the tops of the upper clamping block 14 and the locking block 18. An inclined upward slope is provided on one side of the bottom of the lower clamping block 15 close to the locking block 18.

[0025] The upper clamping block 14 and the lower clamping block 15 are two symmetrically arranged frustums of a cone. A plurality of clamping assemblies are evenly arranged along the circumference on the periphery of the same plugging assembly. The clamping assembly further includes an installation cavity 17 radially opened on the fixing plate 1 and the second connecting ring 16. The locking block 18 is slidably installed in the installation cavity 17. There are various installation methods for the locking block 18. For example, a limiting groove is opened on the inner wall of the installation cavity 17, and a connecting block is slidably installed in the limiting groove. The connecting block is fixedly connected to the locking block 18 to prevent the locking block 18 from detaching from the installation cavity 17.

[0026] When we use this fixing device to fix the logistics box 2, first, move the logistics box 2 onto the fixing plate 1 and make the first connecting ring 3 concentric with the corresponding mounting hole. Then, rotate the rotating handle 11 clockwise to make the ball 8 move along the lower end face of the driving ring 6. When the ball 8 moves to the transition step 601, the top spring 9 pushes the lower connecting rod 5 downward. At this time, the inclined surface of the lower clamping block 15 abuts against the inclined surface of the locking block 18 and squeezes the locking block 18 into the installation cavity 17. When the lower clamping block 15 passes over the locking block 18, the locking block 18 is inserted between the upper clamping block 14 and the lower clamping block 15 under the elastic force of the spring 19, thus completing the fixation of the logistics box 2 and preventing the goods in the logistics box 2 from being damaged due to the up and down vibration of the logistics box 2 when the logistics vehicle is driving on rough roads.

[0027] When it is necessary to unload the logistics box 2, just rotate the rotating handle 11 clockwise again to make the rotating handle 11 move into the V-shaped groove 602. At this time, the top spring 9 pushes the lower connecting rod 5 downward again. During the downward movement of the lower connecting rod 5, the lower end of the upper clamping block 14 abuts against the inclined surface of the locking block 18, so that the tension spring 13 is continuously compressed. When the elastic force of the tension spring 13 is greater than the elastic force of the spring 19, the upper clamping block 14 squeezes the locking block 18 into the installation cavity 17 again and also moves below it. At this time, the upper clamping block 14 and the lower clamping block 15 abut together. Then, rotate the rotating handle 11 clockwise again to make the ball 8 move onto the lower end face of the driving ring 6 again and drive the lower connecting rod 5 upward. Since the upper clamping block 14 and the lower clamping block 15 are in contact with each other, the upper clamping block 14 and the lower clamping block 15 can move above the locking block 18 simultaneously, thus releasing the fixation of the logistics box 2.

[0028] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is as Figure 2 shown. A buffer assembly is provided inside the logistics box 2. The buffer assembly includes annular air bags 20 fixedly sleeved on the inner walls of the upper and lower ends of the logistics box 2, and also includes a plurality of connecting air bags 21 uniformly and fixedly installed between the two annular air bags 20 and communicating with them. An air nozzle 22 is provided on the annular air bag 20 at the upper end of the connecting air bag 21. The buffer assembly is used to buffer the goods in the logistics box, so as to better prevent the goods from being damaged.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
