DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figures 1 to 7 As shown, the decomposable multifunctional wooden tray according to the embodiment of the present invention comprises a bottom plate 4, a first support frame 2, a second support frame 3 and a support plate 1, wherein two first support frames 2 are provided, and the two first support frames 2 are symmetrically arranged on both sides of the bottom plate 4, and the second support frame 3 is located between the two first support frames 2;

[0035] A plurality of support plates 1 are supported by two first support frames 2 and one second support frame 3 above the bottom plate 4 .

[0036] The tops of the first support frame 2 and the second support frame 3 are both opened, and the first support frame 2, the second support frame 3 and the support plate 1 are all provided with reinforcing ribs inside;

[0037] Both ends of the bottom of the support plate 1 are fixedly mounted with bumps, which extend to the inside of the two first support frames 2 respectively;

[0038] The support plate 1 can slide left and right inside the two first support frames 2 through the provided protrusions, so as to limit the movement track of the support plate 1 .

[0039] The first support frame 2, the second support frame 3 and the support plate 1 are all made of wood. The bearing capacity can be improved by the reinforcing rib plate arranged inside, and the protrusion is fixed on the reinforcing rib plate.

[0040] A positioning block 15 is fixedly installed at the bottom end of the support plate 1, a clamping block 20 is elastically installed inside the positioning block 15, and a clamping slot for clamping the clamping block 20 is opened inside the second support frame 3;

[0041] The positioning block 15 is installed on the reinforcing rib plate of the support plate 1. When a lateral force is applied to the support plate 1, the support plate 1 will drive the protrusions at both ends of the bottom surface to slide inside the first support frame 2. At the same time, the support plate 1 will drive the positioning block 15 to slide inside the second support frame 3. When the positioning block 15 slides into the card slot opened inside the second support frame 3, the elastic card block 20 inside the positioning block 15 will pop out and enter the inside of the card slot. The current position of the positioning block 15 can be limited by the cooperation between the card block 20 and the card slot, so that the support plate 1 can be installed and fixed. Multiple support plates 1 are installed in the same way, and the efficiency is higher than the efficiency of binding the support plates 1 by tools in the prior art.

[0042] A bearing plate 6 is fixedly mounted on the bottom end of the bottom plate 4 , a support seat 5 is slidably mounted on the bottom end of the bearing plate 6 , and a pressure sensor 27 is arranged between the bearing plate 6 and the support seat 5 .

[0043] When the goods are placed on the support plate 1, gravity will drive the support plate 1 and the load-bearing plate 6 to slide toward the support seat 5. The current force can be monitored by the pressure sensor 27. The four support seats 5 are all provided with pressure sensors 27. Through pressure comparison and in conjunction with the alarm, the staff can be prompted to adjust the goods on the support seat 5 that exceed the weight range, so as to avoid uneven force on the wooden pallet, excessive local force, and damage to the wooden pallet.

[0044] As a preferred embodiment of the present invention, a rotating rod 18 is rotatably installed inside the positioning block 15 , a pull rope 19 is fixedly connected to the outer wall of the rotating rod 18 , and the other end of the pull rope 19 is fixedly connected to the clamping block 20 .

[0045] When the rotating rod 18 rotates, the pull rope 19 will be reeled in to shorten the pull rope 19 and pull back the card block 20. When the card block 20 is engaged with the card slot, it is only necessary to control the rotation of the rotating rod 18 to pull the card block 20 out of the inside of the card slot through the pull rope 19, so that the installation of the support plate 1 and the second support frame 3 will be released. At this time, the support plate 1 can also slide left and right on the first support frame 2 and the second support frame 3.

[0046] As a preferred embodiment of the present invention, a transmission gear 17 is fixedly installed on the top of the rotating rod 18, a pressing rod 16 is slidably installed inside the support plate 1, a first tooth plate is fixedly installed on the pressing rod 16, the first tooth plate is meshed with the transmission gear 17, and one end of the pressing rod 16 extends out of the outer wall of the support plate 1.

[0047] By pushing the pressing rod 16, the pressing rod 16 will slide inside the support plate 1, and the transmission gear 17 will be driven to rotate under the action of the first tooth plate, and the rotating rod 18 will be rotated to reel in the pull rope 19, and the card block 20 will be pulled out from the inside of the card slot, so that the limit of the support plate 1 is released, the support plate 1 can be disassembled, and the damaged support plate 1 can be flexibly replaced. Compared with the prior art of binding by nails, the replacement is more convenient and faster.

[0048] As a preferred embodiment of the present invention, a second tooth plate 13 is fixedly installed on one side of the support plate 1, and a receiving groove 14 for sliding the second tooth plate 13 is provided at the other end of the support plate 1 away from the second tooth plate 13, and one end of the clamping block 20 facing the second tooth plate 13 is set as a plane, and the other end of the clamping block 20 is set as an inclined surface.

[0049] When the support plate 1 slides from the left side to the right side of the first support frame 2 and the second support frame 3 (that is, the direction in which the inclined surface of the card block 20 is provided), the card block 20 provided with the inclined surface will not be engaged with the card slot. A plurality of card slots are provided inside the second support frame 3, and the plurality of card slots are equidistantly distributed. When installing a plurality of support plates 1, it is only necessary to slide the support plate 1 from the left side to the right side of the first support frame 2 and the second support frame 3 so that the card block 20 provided at the bottom end of each support plate 1 is engaged with the card slot to complete the installation of the plurality of support plates 1.

[0050] When multiple support plates 1 need to be disassembled, first press the pressing rod 16 located inside the support plate 1 on the far right of the second support frame 3. The first tooth plate drives the transmission gear 17 to rotate through the sliding of the pressing rod 16, and the block 20 is pulled back by winding the pull rope 19. At this time, the rightmost support plate 1 is controlled to slide to the left. At this time, the second tooth plate 13 installed on the side wall of the support plate 1 will extend into the accommodating groove 14 opened on the other support plate 1, and control the transmission gear 17 inside the other support plate 1 to rotate, effectively pulling back the block 20 at the bottom of the other support plate 1. As the sliding to the left continues, all the support plates 1 can be removed from the first support frame 2 and the second support frame 3 at one time, which is more efficient.

[0051] As a preferred embodiment of the present invention, a pressure relief cylinder 8 is fixedly installed inside the support seat 5, a sliding rod 7 is slidably installed inside the pressure relief cylinder 8, the top of the sliding rod 7 is fixedly connected to the bottom end of the supporting plate 6, a top pressure block 11 is fixedly installed on the outer wall of the sliding rod 7, the outer wall of the top pressure block 11 is in contact with the inner wall of the pressure relief cylinder 8, a pressure relief spring 12 is arranged between the bottom end of the top pressure block 11 and the pressure relief cylinder 8, a damping fluid is arranged inside the pressure relief cylinder 8, and the damping fluid is located above the top pressure block 11, a pressure relief ring 9 is fixedly installed on the outer wall of the sliding rod 7, the pressure relief ring 9 is arranged above the top pressure block 11, the outer wall of the pressure relief ring 9 is in contact with the inner wall of the pressure relief cylinder 8, and a flow hole 10 for the damping fluid to flow is opened on the pressure relief ring 9.

[0052] When the bottom plate 4 is load-bearing, it will drive the load-bearing plate 6 and the sliding rod 7 to slide toward the pressure relief cylinder 8, so that the sliding rod 7 drives the top pressure block 11 to press the pressure relief spring 12. At the same time, as the pressure relief ring 9 slides down inside the pressure relief cylinder 8, the damping fluid between the pressure relief ring 9 and the top pressure block 11 will flow upward through the flow hole 10 and slow down the potential energy of the downward sliding. Through this shock-absorbing method, the potential energy generated by the acceleration of gravity when the goods are placed can be effectively avoided, which may cause the support seat 5 to be easily damaged, thereby ensuring the service life of the support seat 5.

[0053] As a preferred embodiment of the present invention, a blocking block 21 for blocking the flow hole 10 is slidably installed inside the pressure release ring 9, and one end of the blocking block 21 away from the flow hole 10 is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to the inside of the pressure release ring 9.

[0054] When the blocking block 21 slides toward the inside of the flow hole 10 , it blocks the inner diameter of the flow hole 10 , which can effectively reduce the flow of the damping fluid, thereby further slowing down the sliding speed of the sliding rod 7 .

[0055] Through the setting of this structure, when the weather is cold, the damping fluid is too thick and difficult to flow. At this time, the blocking block 21 is controlled to release the blocking of the flow hole 10. When the weather is hot, the damping fluid is thinner and easy to flow, which will reduce the damping effect. This problem can be solved by controlling the blocking block 21 to slide toward the flow hole 10 to reduce the flow rate.

[0056] As a preferred embodiment of the present invention, a rotating shaft 23 is rotatably mounted inside the pressure release ring 9 , and a cam 22 for pressing the blocking block 21 to slide is fixedly mounted at the bottom end of the rotating shaft 23 .

[0057] By rotating the shaft 23 , the cam 22 can be rotated toward the blocking block 21 , and the blocking block 21 can be pushed into the flow hole 10 . When the shaft 23 is reset and rotated, the blocking block 21 can be reset under the action of elasticity to release the blocking of the flow hole 10 .

[0058] As a preferred embodiment of the present invention, a control gear 24 is fixedly installed on the top of the rotating shaft 23, a sliding groove 25 is opened on the inner top of the pressure release cylinder 8, a gear ring 26 is fixedly installed inside the sliding groove 25, and the control gear 24 is meshed with the gear ring 26.

[0059] When it is necessary to control the rotation of the rotating shaft 23, the pressure release ring 9 slides upward by pulling the sliding rod 7, so that the control gear 24 is inserted into the sliding groove 25. At this time, the sliding rod 7 is rotated, and the control gear 24 can be driven to rotate 90 degrees through the cooperation of the toothed ring 26 in the sliding groove 25, so as to control the cam 22 to push the blocking block 21 toward the circulation hole 10, thereby blocking the circulation hole 10. Conversely, the blocking block 21 can release the blocking of the circulation hole 10.

[0060] Working principle: The pressure of the goods on the support plate 1 is detected by the pressure sensor 27, so that the load-bearing plate 6 slides toward the support seat 5. The current force can be monitored by the set pressure sensor 27. The four support seats 5 are all provided with pressure sensors 27. Through pressure comparison, combined with the alarm, the staff can be prompted to adjust the goods on the support seat 5 that exceed the weight range, so as to avoid uneven force on the wooden pallet, excessive local force, and damage to the wooden pallet.

[0061] When the support plate 1 is slid from the left side to the right side of the first support frame 2 and the second support frame 3, the block 20 set on the inclined surface will not be engaged with the slot. A plurality of slots are provided inside the second support frame 3, and the plurality of slots are equidistantly distributed. When installing a plurality of support plates 1, it is only necessary to slide the support plate 1 from the left side to the right side of the first support frame 2 and the second support frame 3 so that the block 20 set at the bottom end of each support plate 1 is engaged with the slot to complete the installation of the plurality of support plates 1.

[0062] When multiple support plates 1 need to be disassembled, first press the pressing rod 16 located inside the support plate 1 on the far right of the second support frame 3. The first tooth plate drives the transmission gear 17 to rotate through the sliding of the pressing rod 16, and the block 20 is pulled back by winding the pull rope 19. At this time, the rightmost support plate 1 is controlled to slide to the left. At this time, the second tooth plate 13 installed on the side wall of the support plate 1 will extend into the accommodating groove 14 opened on the other support plate 1, and control the transmission gear 17 inside the other support plate 1 to rotate, effectively pulling back the block 20 at the bottom of the other support plate 1. As the sliding to the left continues, all the support plates 1 can be removed from the first support frame 2 and the second support frame 3 at one time, which is more efficient.

[0063] By lifting the sliding rod 7, the pressure release ring 9 slides upward and the control gear 24 is inserted into the sliding groove 25. At this time, the sliding rod 7 is rotated, and the control gear 24 can be driven to rotate 90 degrees through the cooperation of the toothed ring 26 in the sliding groove 25, so as to control the cam 22 to push the blocking block 21 toward the flow hole 10 to achieve the blocking of the flow hole 10. Conversely, the blocking block 21 can release the blocking of the flow hole 10. Through the setting of this structure, when the weather is cold, it can deal with the problem that the damping fluid is too thick and difficult to flow. When the weather is hot, the damping fluid is easy to flow to reduce the damping effect, thereby ensuring the damping effect and effectively improving the service life of the support seat 5.
