Description

Technical Field

[0001] This application relates to the field of logistics pallets, and in particular to a high-performance composite plastic pallet with protective functions. Background Technology

[0002] As a fundamental piece of equipment in the logistics system, the importance of logistics pallets is becoming increasingly prominent. With their standardized and unitized characteristics, pallets enable the containerized transportation of goods, greatly improving the efficiency of loading and unloading, reducing the heavy manual labor of handling, and lowering logistics costs. With the development of the logistics industry, the performance requirements for pallets are getting higher and higher. High-performance composite plastic pallets have good strength, impact resistance, high modulus support, wear resistance, weather resistance, and anti-aging properties.

[0003] Chinese Patent CN217805907U discloses a protective logistics pallet, belonging to the field of logistics pallet technology. It includes several crossbeams, with an adjustable base fixedly connected to each crossbeam. The adjustable base includes an adjustable base and a concealed locking component. A plug-in protective component is movably connected to the adjustable base. The plug-in protective component includes a sleeve, a block, an angle steel limiting plate, and a horizontal connecting plate. Through this method, the size of the logistics pallet can be adjusted to accommodate different sizes of goods and change the load-bearing capacity of the adjustable base. By setting plug-in protective components on the left and right sides of the logistics pallet, this invention provides a four-corner limiting function, which can limit the goods when the logistics pallet shakes, preventing them from tipping over and providing cargo protection.

[0004] Regarding the aforementioned technologies, the inventors believe that when using logistics pallets, the positioning holes are usually set at fixed intervals, which means that the extension length of the pallet can only be adjusted according to these intervals, and cannot meet more precise size adjustments. Furthermore, the use of plug-in protective components can lead to safety hazards if they are accidentally pulled out during use. Therefore, a high-performance composite plastic pallet with protective functions is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the technical issues that when using logistics pallets, the extension length can only be adjusted according to the interval of the positioning holes, which cannot meet more precise size adjustments, and that the use of plug-in protective components can pose a safety hazard if accidentally pulled out during use, this application provides a high-performance composite plastic pallet with protective functions.

[0006] This application provides a high-performance composite plastic pallet with protective functions, using the following technical solution:

[0007] A high-performance composite plastic pallet with protective function includes a support frame, the support frame having an adjustment device inside, the adjustment device including a telescopic frame, the telescopic frame extending and retracting to adjust the length of the logistics pallet.

[0008] The outer surface of the support frame is provided with a protective device, which includes a protective frame that protects the items when unfolded.

[0009] Optionally, the adjustment device further includes a fixing rod, and the bottom of each of the multiple support frames is fixedly installed with a support rod. The fixing rod is slidably inserted into the groove of the support rod. The multiple support frames are arranged in pairs, and the opposite surfaces of each pair of support frames are slidably inserted into the two side surfaces of one telescopic frame. The support frames and the telescopic frame are made of glass fiber reinforced plastic.

[0010] Optionally, the front end surface of the support rod is threaded with a star-head bolt, one end of which penetrates and extends into the inner wall of the groove of the support rod and is rotatably connected to one end of the fixing rod.

[0011] Optionally, multiple fixing blocks are fixedly installed on the upper surface of the fixing rod, and a plug-in groove is also provided at the front end of the support frame. The top surface of the fixing block is slidably inserted into the inner wall of the plug-in groove, and the rear surface of the fixing block is in contact with the surface of the telescopic rod of the telescopic frame.

[0012] Optionally, the protective device further includes a support rod, which is fixedly installed on the outer side wall of the support frame and the outer side wall of the telescopic frame, respectively.

[0013] Optionally, the protective frame is rotatably connected to the inner wall of the groove of the support rod, and multiple ball sticks are slidably inserted into the groove of the rotating rod installed on the lower surface of the protective frame. A limiting groove is formed on the inner wall of the support rod, and the inner wall of the limiting groove is slidably engaged with the outer surface of the ball stick.

[0014] Optionally, a spring is fixedly installed on the lower surface of the cue stick, and the spring is fixedly installed in a rotating rod groove installed on the lower surface of the protective frame. A handle is fixedly installed on the upper surface of the protective frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. By setting an adjustment device, the length of the logistics pallet can be adjusted. The fixed rod and the support frame are slidably connected. The telescopic frame and the support frame are also slidably connected. The telescopic rod of the telescopic frame has sliders fixedly installed on both sides at one end. The inner side wall of the support frame has a groove that matches the slider. Through the design of the slider and the groove, the maximum extension distance of the telescopic frame is limited. Rotating the star head bolt can drive the fixed rod connected to it to move within the slidably connected support rod. The movement of the fixed rod drives the fixed block to move synchronously, thereby fixing the telescopic rod of the telescopic frame and preventing the telescopic rod from shifting after extension and retraction. This solves the technical problem that when using logistics pallets, the positioning holes are usually set at fixed intervals, which means that the extension length of the pallet can only be adjusted according to these intervals and cannot meet the technical problem of more precise size adjustment.

[0017] 2. By setting up a protective device, the items are protected. The protective frame is rotatably connected to the support rod. The support rod has two limiting grooves, one on the X-axis and one on the Y-axis. The inner angle of the circle formed is a right angle, and the cross-section is triangular, which can provide precise guidance to ensure the correct reset and engagement of the ball. The springs are fixedly installed on the ball and the protective frame respectively, which can reset the ball after it moves, thereby engaging with the limiting groove. The protective frame is fixedly installed on the handle, which makes it easy for workers to carry the logistics pallet with the handle. This solves the technical problem that when using plug-in protective components, the accidental pull-out during use can cause safety hazards. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0027] Reference Figures 1-7 A high-performance composite plastic pallet with protective function includes a support frame 1. The support frame 1 is provided with an adjustment device, which includes a telescopic frame 21. The telescopic frame 21 adjusts the length of the logistics pallet by extending and retracting.

[0028] To limit the maximum extension distance of the telescopic frame 21, the adjustment device also includes a fixing rod 2. Support rods 11 are fixedly installed at the bottom of multiple support frames 1. The fixing rod 2 is slidably inserted into the groove of the support rod 11. Multiple support frames 1 are arranged in pairs, with the opposing surfaces of each pair of support frames 1 slidably inserted into the two side surfaces of a telescopic frame 21. The support frames 1 and telescopic frame 21 are made of glass fiber reinforced plastic. The support frames 1 are fixed to the support rods 11, and the fixing rod 2 is slidably inserted into the support rods 11, fixing them without affecting their movement. The telescopic frame 21 is connected to the support frames... 1. Sliding connection, which fixes the telescopic frame 21 without affecting its rotation. Sliders are fixedly installed on both sides of one end of the telescopic rod. The inner side wall of the support frame 1 is provided with a sliding groove that matches the slider. Through the design of the slider and the sliding groove, the maximum extension distance of the telescopic frame 21 is limited to prevent excessive extension, which would cause the telescopic frame 21 to separate from the support frame 1. The support frame 1 and the telescopic frame 21 are made of glass fiber reinforced plastic, which has excellent mechanical properties, can withstand large loads without deformation, ensures the stability and durability of the pallet, and has good chemical corrosion resistance, making it suitable for various complex environments.

[0029] To achieve precise position adjustment of the fixed rod 2, a star-head bolt 3 is threaded onto the front end surface of the support rod 11. One end of the star-head bolt 3 penetrates and extends into the inner wall of the groove of the support rod 11 and is rotatably connected to one end of the fixed rod 2. By threading the support rod 11 and the star-head bolt 3, and rotatably connecting one end of the star-head bolt 3 to the fixed rod 2, rotating the star-head bolt 3 can drive the fixed rod 2, which is rotatably connected to it, to move within the slidingly inserted support rod 11, thereby achieving precise position adjustment of the fixed rod 2.

[0030] To prevent the telescopic pole from shifting after extension and retraction, multiple fixing blocks 4 are fixedly installed on the upper surface of the fixing rod 2. A plug-in groove is also provided at the front end of the support frame 1. The top surface of the fixing block 4 slides into the inner wall of the plug-in groove, and the rear surface of the fixing block 4 contacts the surface of the telescopic pole of the telescopic frame 21. The fixing rod 2 and the fixing block 4 are fixedly installed and fixed. The plug-in groove is provided on the support frame 1, and the plug-in groove slides into the fixing block 4 without affecting the contact between the fixing block 4 and the telescopic pole of the telescopic frame 21. The movement of the fixing rod 2 drives the fixing block 4 to move synchronously, thereby fixing the telescopic pole of the telescopic frame 21 and preventing the telescopic pole from shifting after extension and retraction.

[0031] The length of the logistics pallet is adjusted by setting an adjustment device. The fixed rod 2 is slidably inserted into the support frame 1, and the telescopic frame 21 is slidably inserted into the support frame 1. Slider blocks are fixedly installed on both sides of one end of the telescopic rod of the telescopic frame 21. The inner side wall of the support frame 1 is provided with a sliding groove that matches the slider. Through the design of the slider and the sliding groove, the maximum extension distance of the telescopic frame 21 is limited. Rotating the star head bolt 3 can drive the fixed rod 2, which is rotatably connected to it, to move within the slidably inserted support rod 11. The movement of the fixed rod 2 drives the fixed block 4 to move synchronously, thereby fixing the telescopic rod of the telescopic frame 21 and preventing the telescopic rod from shifting after extension and retraction. This solves the technical problem that when using logistics pallets, the positioning holes are usually set at fixed intervals, which means that the extension and retraction length of the pallet can only be adjusted according to these intervals, and cannot meet the technical problem of finer size adjustment.

[0032] In order to protect the items, the outer surface of the support frame 1 is provided with a protective device, which includes a protective frame 6. The protective frame 6 protects the items when it is unfolded.

[0033] In order to protect the items, the protective device also includes support rods 5, which are fixedly installed on the outer side wall of the support frame 1 and the outer side wall of the telescopic frame 21 respectively. The support rods 5 are installed on both the support frame 1 and the telescopic frame 21 and fixed thereto, so that the protective frame 6 rotatably connected to the support rods 5 can protect the items.

[0034] To ensure the correct reset and engagement of the cue stick 61, the protective frame 6 is rotatably connected to the inner wall of the groove in the support rod 5. Multiple cue sticks 61 are slidably inserted into the groove of the rotating rod installed on the lower surface of the protective frame 6. The inner wall of the support rod 5 has a limiting groove 62, and the inner wall of the limiting groove 62 is slidably engaged with the outer surface of the cue stick 61. The protective frame 6 is rotatably connected to the support rod 5, fixing it without affecting its rotation. The protective frame 6 is slidably inserted into the cue stick 61, fixing it without affecting its movement. The support rod 5 has two limiting grooves 62, one located on the X-axis and one on the Y-axis, forming a circle with a right angle and a triangular cross-section, which can provide precise guidance to ensure the correct reset and engagement of the cue stick 61.

[0035] To facilitate the handling of the logistics pallet after items have been placed on it by staff using handle 71, a spring 7 is fixedly installed on the lower surface of the cue stick 61. The spring 7 is fixedly installed in the rotating rod groove installed on the lower surface of the protective frame 6. A handle 71 is fixedly installed on the upper surface of the protective frame 6. The spring 7 is fixedly installed on the cue stick 61 and the protective frame 6 respectively, so that the cue stick 61 can be moved and then reset to engage with the limiting groove 62. The protective frame 6 is fixedly installed on the handle 71 to secure it, making it convenient for staff to handle the logistics pallet after items have been placed on it using handle 71.

[0036] By setting up a protective device, the items are protected. The protective frame 6 is rotatably connected to the support rod 5. The support rod 5 has two limiting grooves 62, one located on the X-axis and the other on the Y-axis. The inner angle of the circle formed is a right angle, and the cross-section is triangular, which can provide precise guidance to ensure the correct reset and engagement of the ball rod 61. The spring 7 is fixedly installed on the ball rod 61 and the protective frame 6 respectively, which can reset the ball rod 61 after it moves, so as to engage with the limiting groove 62. The protective frame 6 is fixedly installed on the handle 71, which makes it convenient for staff to carry the logistics pallet after placing the items through the handle 71. This solves the technical problem that when using plug-in protective components, the accidental pull-out during use can cause safety hazards.

[0037] Working principle: When the length of the plastic pallet needs to be adjusted, the operator moves the telescopic frame 21, which is slidably connected to the support frame 1, according to the length of the items to be placed. When the required distance is reached, the star head bolt 3 is rotated, which drives the fixed rod 2, which is rotatably connected to it, to move within the slidably connected support rod 11 until the fixing block 4 on the fixed rod 2 contacts the telescopic rod of the telescopic frame 21, thereby fixing it and preventing displacement. The support frame 1 and the telescopic frame 21 are made of glass fiber reinforced plastic, which has excellent mechanical properties, can withstand large loads without easily deforming, ensures the stability and durability of the pallet, and has good chemical corrosion resistance, making it suitable for various complex environments.

[0038] When the protective frame 6 on the logistics pallet needs to be unfolded to protect the items to be placed thereafter, the staff rotates the protective frame 6 on the support rod 5 by using the handle 71. The ball rod 61 located in the limiting groove 62 on the X-axis is squeezed and moves into the rotating rod groove of the protective frame 6. When the ball rod 61 moves into the limiting groove 62 on the Y-axis, under the action of the spring 7, the ball rod 61 returns to its original position and engages with the limiting groove 62 on the Y-axis.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
