[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the arrangement of the buffer spring and the buffer plate, when placing goods, the elasticity of the buffer spring can be used to buffer and support the impact of the goods, thereby reducing the impact of the goods on the buffer plate and reducing the damage probability of the buffer plate. Through the arrangement of the buffer plate, when the goods are in contact with the buffer plate, even if the goods are heavy and the buffer plate is damaged due to the impact of stacking goods, only the buffer plate needs to be replaced, thereby reducing the maintenance cost;

[0019] 2. Through the arrangement of the clamping convex rod, when installing the truck bed bottom plate, only the lower end of the first connecting block needs to pass through the first clamping groove and the second clamping groove, and the upper end of the clamping convex rod coincides with the lower end of the inner sliding sleeve, and then the first connecting block is rotated to make the clamping convex rod and the inner sliding sleeve clamped, and the installation of the buffer plate can be completed. Thus, the installation of the buffer plate is relatively convenient, and it is convenient for replacement and maintenance when the buffer plate is damaged later, which is convenient for installation and use. At the same time, the production cost is low and the practicability is high. Through the arrangement of the end groove, after the first connecting block is installed, the upper end surface of the first connecting block coincides with the upper end surface of the buffer plate, ensuring the flatness of the upper end of the buffer plate and reducing the occupied space, thereby facilitating the stacking of goods;

[0020] 3. Through the arrangement of the acoustic rangefinder, it is used to detect the distance of the lower end of the first connecting block, so that the magnitude of the pressure received can be calculated according to the degree of movement of the first connecting block, and then the weight of the stacked goods can be calculated. It can not only detect whether the goods are overloaded, but also detect the weight difference on the side of the truck bed bottom plate. Thus, when the goods are stacked, the goods on both sides of the truck bed bottom plate can be adjusted, thereby preventing the weight from being uneven and causing the truck to roll over, thereby increasing the use safety;

[0021] 4. Through the arrangement of the end clamping block, it is used to limit the connection between the limiting rod and the mounting clamping block, thereby preventing the limiting rod and the mounting clamping block from being disconnected due to the vibration of the vehicle when the truck moves, thereby increasing the stability of the installation of the acoustic rangefinder.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the present invention provides a technical solution: a load-bearing detection and support tooling for a light truck, including a truck bed bottom plate 1. Side baffles 11 are provided on the four sides at the upper end of the truck bed bottom plate 1. A second connecting block 23 is fixedly connected to the lower end of the truck bed bottom plate 1. Mounting columns 3 are fixedly connected to the four corners at the lower end of the truck bed bottom plate 1. Sliding inner grooves 24 are provided inside the mounting columns 3 and the second connecting block 23. Inner sliding sleeves 25 are slidably clamped inside the sliding inner grooves 24. Inner mounting grooves 29 are provided at the lower ends of the inner sliding sleeves 25. A buffer spring 26 is fixedly connected between the upper end of the inner mounting groove 29 and the lower end of the sliding inner groove 24. First clamping grooves 27 are provided in the middle of the inner sliding sleeves 25. A buffer plate 22 is provided above the truck bed bottom plate 1. An end setting groove 210 is provided at the upper end of the buffer plate 22. A second clamping groove 211 is provided through the lower end of the end setting groove 210. The second clamping groove 211 communicates with the first clamping groove 27. A first connecting block 2 is clamped between the second clamping groove 211 and the first clamping groove 27. A clamping convex rod 28 is fixedly connected to the lower end of the outer surface of the first connecting block 2. When the lower end of the buffer plate 22 contacts the upper end of the truck bed bottom plate 1, the distance between the lower end of the inner sliding sleeve 25 and the lower end of the sliding inner groove 24 is equal to the height of the clamping convex rod 28. The clamping convex rod 28 is used to connect the buffer plate 22 and the inner sliding sleeve 25.

[0037] Working principle of this embodiment: Through the settings of the buffer spring 26 and the buffer plate 22, when placing goods, the elasticity of the buffer spring 26 can be used to buffer and support the impact of the goods, thereby reducing the impact of the goods on the buffer plate 22 and reducing the damage probability of the buffer plate 22. Through the setting of the buffer plate 22, the goods are in contact with the buffer plate 22. Even if the goods are heavy and the buffer plate 22 is damaged due to the impact of stacking goods, only the buffer plate 22 needs to be replaced, thereby reducing the maintenance cost. Through the setting of the clamping convex rod 28, when installing the bottom plate 1 of the truck bed, only the lower end of the first connecting block 2 needs to pass through the first clamping groove 27 and the second clamping groove 211, and the upper end of the clamping convex rod 28 coincides with the lower end of the inner sliding sleeve 25. Then rotate the first connecting block 2 to make the clamping convex rod 28 and the inner sliding sleeve 25 clamped, and the installation of the buffer plate 22 can be completed. Thus, the installation of the buffer plate 22 is relatively convenient, and it is also convenient for replacement and maintenance when the buffer plate 22 is damaged later, which is convenient for installation and use. At the same time, the production cost is relatively low, and the practicability is relatively high. Through the setting of the end slot 210, after the first connecting block 2 is installed, the upper end surface of the first connecting block 2 coincides with the upper end surface of the buffer plate 22, ensuring the flatness of the upper end of the buffer plate 22 and reducing the occupied space, thereby facilitating the stacking of goods;

[0038] At the same time, according to Figure 1 、 Figure 3 and Figure 4 shown, the upper end of the first connecting block 2 is clamped with the end slot 210. A connecting slot 21 is opened at the upper end of the first connecting block 2. The connecting slot 21 is used to facilitate the rotation of the first connecting block 2, thereby facilitating the installation and disassembly of the first connecting block 2.

[0039] At the same time, according to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 shown, a communicating bottom slot 34 is opened at the lower end of the mounting post 3. The lower end of the mounting post 3 is fixedly connected with a mounting sleeve 31. A buffer sleeve 35 is fixedly connected to the inner wall of the mounting sleeve 31. The buffer sleeve 35 is used to protect the side of the acoustic rangefinder 36, reduce the wear of the acoustic rangefinder 36 during use, and thus increase the service life of the acoustic rangefinder 36.

[0040] At the same time, according to Figure 7As shown, an ultrasonic rangefinder 36 is provided inside the mounting post 3. The ultrasonic rangefinder 36 is snap-connected to the buffer sleeve 35. The ultrasonic rangefinder 36 is used to detect the distance to the lower end of the first connecting block 2, so that the magnitude of the pressure received can be calculated according to the degree of movement of the first connecting block 2, and thus the weight of the stacked goods can be calculated. It can not only detect whether the goods are overloaded, but also detect the weight difference on the side of the truck bed bottom plate 1. Therefore, when the goods are stacked, the goods on both sides of the truck bed bottom plate 1 can be adjusted, so as to prevent the weight from causing the truck to roll over and increase the safety of use.

[0041] At the same time, according to Figure 7 - Figure 9 As shown, mounting blocks 38 are fixedly connected to both sides of the middle part of both sides of the mounting sleeve 31. The lower end of the mounting sleeve 31 is provided with a mounting bottom plate 32. Mounting side plates 37 are fixedly connected to the middle parts of both sides of the mounting bottom plate 32. The mounting side plates 37 are snap-connected to the mounting blocks 38. The mounting bottom plate 32 is used to limit the lower end of the ultrasonic rangefinder 36, so as to mount the ultrasonic rangefinder 36.

[0042] At the same time, according to Figure 7 - Figure 9 As shown, clamping side grooves 311 are formed inside both the mounting block 38 and the mounting side plate 37. A limiting rod 39 is clamped inside the clamping side groove 311. The limiting rod 39 is used to clamp between the mounting side plate 37 and the mounting block 38, so that the installation of the mounting bottom plate 32 is more convenient.

[0043] At the same time, according to Figure 7 - Figure 9 As shown, a limiting end groove 314 is formed in the middle of the upper end of one of the mounting blocks 38 on the side of the mounting sleeve 31. A limiting card slot 313 is formed on one side of the upper end of the limiting rod 39. The limiting card slot 313 communicates with the limiting end groove 314. An end card block 312 is clamped between the limiting card slot 313 and the limiting end groove 314. Through the setting of the end card block 312, it is used to limit the connection between the limiting rod 39 and the mounting block 38, so as to prevent the limiting rod 39 from disconnecting from the mounting block 38 due to the vibration of the vehicle when the truck is moving, thereby increasing the stability of the installation of the ultrasonic rangefinder 36.

[0044] At the same time, according to Figure 4 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, a buffer pad 310 is provided between the upper end of the mounting base plate 32 and the lower end of the acoustic rangefinder 36. A clamping end groove 33 is formed at the upper end of the sliding inner groove 24, and a sealing rubber pad 315 is fixedly connected inside the clamping end groove 33. The buffer pad 310 is used to buffer and protect the lower end of the acoustic rangefinder 36, thereby further protecting the acoustic rangefinder 36 and further increasing the service life of the acoustic rangefinder 36. Through the setting of the sealing rubber pad 315, it is used to fill the gap between the inner sliding sleeve 25 and the sliding inner groove 24 to prevent moisture from contacting the acoustic rangefinder 36 and causing damage to the acoustic rangefinder 36, thereby ensuring the normal use of the acoustic rangefinder 36.

[0045] At the same time, according to Figure 1 - Figure 2 As shown in the figure, a connecting frame 12 is fixedly connected to the outer edge of the lower end of the truck bed bottom plate 1, and the connecting frame 12 is used for installation with the truck frame.

[0046] At the same time, according to Figure 1 - Figure 2 As shown in the figure, a first reinforcing rib 13, a second reinforcing rib 14, a third reinforcing rib 15, and a fourth reinforcing rib 16 are fixedly connected to the lower end of the truck bed bottom plate 1. The first reinforcing rib 13, the second reinforcing rib 14, the third reinforcing rib 15, and the fourth reinforcing rib 16 are used to increase the support strength of the truck bed bottom plate 1, thereby further preventing damage to the truck bed bottom plate 1.

[0047] Working principle: When in use, stack the goods on the buffer plate 22. Through the elasticity of the buffer spring 26, buffer the impact force during the stacking of the goods, thereby preventing damage to the buffer plate 22. At the same time, due to the extrusion of the goods, the inner sliding sleeve 25 will move downward, causing the position of the first connecting block 2 to change. Through the acoustic rangefinder 36, measure the position of the first connecting block 2, thereby calculating the weight of the goods. According to the deviation of the weight, adjust the stacking position of the goods. After loading is completed, transportation can be carried out. When the buffer plate 22 is damaged, the first connecting block 2 can be rotated to make the clamping convex rod 28 move, and then the first connecting block 2 can be pulled out, and a new buffer plate 22 can be installed. When installing the acoustic rangefinder 36, insert the acoustic rangefinder 36 into the installation sleeve 31, then insert the installation side plate 37 between the two installation blocks 38, and then insert the limit rod 39 into the clamping side groove 311 to initially fix the installation side plate 37. Then insert the end block 312 into 214 and the limit card slot 313 to limit the position of the limit rod 39, and the installation can be completed.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
