The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0040] like Figure 1As shown in Figure 16, this invention provides a mixed-loading and locking platform for multiple goods, including a platform base frame 1 and a front crossbeam 2 and a rear crossbeam 3 fixedly mounted on the upper end of the platform base frame 1. The front crossbeam 2 includes a crossbeam frame 21 fixedly mounted on the platform base frame 1, and multiple pairs of slidable and adjustable sliding plates 22 are fixedly mounted on the crossbeam frame 21. Each pair of two sliding plates 22 has a left support block 25 and a right support block 26 fixedly mounted on their upper ends. The support blocks 26 are symmetrically arranged on the left and right sides. There are three cargo pressing positions on both the left and right support blocks 25 and 26. Each cargo pressing position has a corresponding pressing groove on one side. A cargo pressing block is slidably arranged inside each pressing groove. A locking mechanism 27 is provided on the crossbeam frame 21. The locking mechanism 27 includes two left and right sliding tie rods. All cargo pressing blocks on the left support block 25 are connected to one of the tie rods, and all cargo pressing blocks on the right support block 26 are connected to the other tie rod.
[0041] The platform base frame 1 includes upper and lower anti-slip platform plates 12 and a frame body 11. The frame body 11 is a square frame structure formed by multiple horizontal beams and longitudinal beams fixedly connected to each other. The number of longitudinal beams and horizontal beams varies depending on the actual weight of the load. The beams and longitudinal beams are fixedly connected to each other by welding or bolts. Multiple bolt seats are fixedly installed at the outer edge of the lower end face of the frame body 11. Multiple bolts pass through the bolt seats to fix the frame body 11 to the carriage. The anti-slip platform plates 12 are horizontally arranged square plate structures and are fixedly installed on the upper end of the frame body 11.
[0042] The crossbeam frame 21 includes a frame 2101 and two frame guide rails 2102. The frame 2101 is a U-shaped plate structure extending left and right, and is fixedly mounted on the platform base 1. Two horizontally extending frame guide rails 2102 are fixedly mounted on the bottom surface inside the frame 2101, and are installed on the frame 2101 by countersunk screws.
[0043] The sliding plate 22 is a transitional component used to connect the crossbeam frame 21 with the left support block 25 and the right support block 26. It includes a sliding plate body 2201, sliding plate guide blocks 2202, adjusting sliders 2203, adjusting screws 2204, and a first magnet 2303. The sliding plate body 2201 is a horizontally positioned cuboid structure. Two symmetrical first mounting slots are provided on the lower end face of the sliding plate body 2201, and these slots are connected to the left and right end faces of the sliding plate body 2201. A sliding plate guide block 2202 is fixedly installed inside each first mounting slot. Multiple countersunk bolts pass downwards from the upper end face of the sliding plate body 2201 and are screwed onto the upper end face of the sliding plate guide block 2202, thus installing the sliding plate guide block 2202 inside the first mounting slot. The two sliding plate guide blocks 2202 on the sliding plate body 2201 are slidably engaged with the front and rear frame guide rails 2102, allowing the sliding plate 22 to slide stably left and right inside the crossbeam frame 21.
[0044] A first slide groove is provided at the center of the front and rear end faces of the slide plate 2201. An adjusting slider 2203 is slidably mounted in each first slide groove along the left-right direction. A first fixing hole 2205 is provided on the outer surface of the adjusting slider 2203. A threaded hole extending left and right is provided on the inner wall of each left and right side of each first slide groove, communicating with the outer surface of the slide plate 2201. An adjusting screw 2204 is screwed into each threaded hole, with one inner end of the adjusting screw 2204 rotatably connected to the end face of the adjusting slider 2203. By rotating the outer end of either the left or right adjusting screw 2204, the adjusting screw 2204 can be controlled to move axially within the threaded hole, thereby causing the adjusting slider 2203 to slide left and right within the first slide groove.
[0045] Multiple first insertion holes are arranged along the left-right direction on the side walls of the front and rear sides of the frame 2101. A first pin 23 is inserted into each first insertion hole, with the first pin 23 on the front side corresponding to the first pin 23 on the rear side. The corresponding first pins 23 on the front and rear sides are respectively inserted into the first fixing holes 2205 of the two adjusting sliders 2203 on the same slide body 2201, thereby initially locking the left and right position of the slide body 2201. At this time, by simultaneously rotating the outer ends of the two adjusting screws 2204 on the left side of the slide body 2201 or simultaneously rotating the outer ends of the two adjusting screws 2204 on the right side of the slide body 2201, the two adjusting sliders 2203 can be controlled to slide left or right simultaneously within the first sliding groove of the slide body 2201. Since the two adjusting sliders 2203 are fixed by the first pins 23 and cannot move, the slide body 2201 slides left and right relative to the adjusting sliders 2203, thereby fine-tuning the position of the individual slide body 2201.
[0046] The first pin 23 includes a first handle 2301, a first pin shaft 2302, and a first magnet 2303. One end of the first pin shaft 2302 is fixed to the first handle 2301 by two set screws. The first magnet 2303 is also fixed to the first handle 2301 by screws. When the first pin shaft 2302 of the first pin 23 is inserted from the outside of the first insertion hole inward, the first magnet 2303 on the first pin 23 is magnetically attracted and fixed to the outer surface of the frame 2101, so that the first pin 23 is fixedly connected to the frame 2101 and will not accidentally detach or move axially.
[0047] A first mounting hole 2206 is provided at the center of the upper end face of the skateboard body 2201. A second insertion hole extending to the left and right is provided on the inner walls of the left and right sides of each first mounting hole 2206. The ends of the two second insertion holes away from the first mounting hole 2206 are respectively connected to the left and right end faces of the skateboard body 2201. A second magnet 2207 is fixedly installed at the center of the left and right end faces of the skateboard body 2201. The second magnets 2207 are fixed to the skateboard body 22 by screws, and the two second magnets 2207 are located on the outer side of the opening of the two second insertion holes.
[0048] For the left support block 25 on the front crossbeam 2, the left support block 25 is a horizontally arranged block structure. A vertical insertion rod 2501 is fixedly installed at the center of the lower end face of the left support block 25, and a pin hole 2502 is provided on the outer side of the insertion rod 2501. The insertion rod 2501 at the lower end of the left support block 25 is inserted into the first mounting hole 2206 at the center of the upper end face of the slide plate 2201, and a second pin 24 is inserted from one of the second insertion holes and inserted into the pin hole 2502 of the insertion rod 2501, thereby fixing the left support block 25 to the slide plate 2201.
[0049] The second pin 24 includes a second handle 2401 and a second pin shaft 2402. One end of the second pin shaft 2402 is fixedly connected to one end of the second handle 2401 by two set screws. When the second pin 24 is inserted into the second insertion hole, the second handle 2401 of the second pin 24 is magnetically attracted and fixed to the second magnet 2207, thereby ensuring that the second pin 24 will not accidentally come off, and at the same time ensuring that the second pin 24 will not move axially.
[0050] A cargo A pressing position 2503 is provided on the right rear end of the left support block 25. A first pressing groove 2504 is provided on the left side of the cargo A pressing position 2503, and the right end of the first pressing groove 2504 is connected to the cargo A pressing position 2503. A cargo B pressing position 2505 is provided in the middle of the rear end of the left support block 25. The cargo B pressing position 2505 is located above the first pressing groove 2504. A second pressing groove 2506 is provided on the left side of the cargo B pressing position 2505, and the right end of the second pressing groove 2506 is connected to the cargo B pressing position 2505.

A third pressing groove 2508 is provided on the left side of the cargo C pressing position 2507, and the right end of the third pressing groove 2508 is connected to the cargo C pressing position 2507.
[0051] For the locking mechanism 27 on the front crossbeam 2, the locking mechanism 27 also includes a fixed base 2701, a connecting end 2704, and an operating handle 2705.
[0052] A row of fixed seats 2701 is fixedly installed at the rear end of the frame 2101 of the front crossbeam 2 along the left and right direction. Two tie rods are slidably installed on the fixed seats 2701. The two tie rods are the first tie rod 2702 and the second tie rod 2703. The first tie rod 2702 and the second tie rod 2703 are both round rod structures arranged horizontally left and right, with the first tie rod 2702 located above the second tie rod 2703.
[0053] A connecting end 2704 is fixedly installed on the leftmost and rightmost fixed bases 2701, respectively. An operating handle 2705 is rotatably mounted on each connecting end 2704 via a pin. Each operating handle 2705 has two oblong grooves 2706, the length of which coincides with the length of the operating handle 2705. An actuating rod 2707 is fixedly installed at each end of the first pull rod 2702 and the second pull rod 2703, with the axis of the actuating rod 2707 perpendicular to the axes of the first pull rod 2702 and the second pull rod 2703. The actuating rods 2707 at both ends of the first pull rod 2702 are slidably engaged with the oblong grooves 2706 on the upper side of the two operating handles 2705, and the actuating rods 2707 at both ends of the second pull rod 2703 are slidably engaged with the oblong grooves 2706 on the lower side of the two operating handles 2705. The first lever 2702, the second lever 2703, and the two operating handles 2705 form a parallelogram linkage structure.
[0054] A cargo A pressing block 2708 is slidably disposed inside the first pressing block groove 2504 along the left and right direction; a cargo B pressing block 2709 is slidably disposed inside the second pressing block groove 2506 along the left and right direction; and a cargo C pressing block 2710 is slidably disposed inside the third pressing block groove 2508 along the left and right direction.
[0055] Multiple sets of connecting rods are fixedly installed on the second pull rod 2703, and the number of connecting rod sets corresponds to the number of left support blocks 25. Each set of connecting rods includes a first connecting rod 2711, a second connecting rod 2712, and a third connecting rod 2713. The end of the first connecting rod 2711 away from the second pull rod 2703 is fixedly connected to the cargo A pressure block 2708 inside the left support block 25. The end of the second connecting rod 2712 away from the second pull rod 2703 is fixedly connected to the cargo B pressure block 2709 inside the left support block 25. The end of the third connecting rod 2713 away from the third pull rod is fixedly connected to the cargo C pressure block 2710 inside the left support block 25.
[0056] Multiple sets of connecting rods are fixedly installed on the first pull rod 2702, and the number of connecting rod sets corresponds to the number of right-side support blocks 26. Each set of connecting rods includes a first connecting rod 2711, a second connecting rod 2712, and a third connecting rod 2713. The end of the first connecting rod 2711 away from the second pull rod 2703 is fixedly connected to the cargo A pressure block 2708 inside the right-side support block 26. The end of the second connecting rod 2712 away from the second pull rod 2703 is fixedly connected to the cargo B pressure block 2709 inside the right-side support block 26. The end of the third connecting rod 2713 away from the third pull rod is fixedly connected to the cargo C pressure block 2710 inside the right-side support block 26.
[0057] When the upper end of any one of the operating handles 2705 is turned to the left, the lower end of the operating handle 2705 is turned to the right, thereby causing the first pull rod 2702 to slide to the left inside the fixed base 2701, and causing the second pull rod 2703 to slide to the right inside the fixed base 2701. The first pull rod 2702, through the first connecting rod 2711, the second connecting rod 2712, and the third connecting rod 2713, respectively causes the cargo A pressing block 2708, cargo B pressing block 2709, and cargo C pressing block 2710 to slide to the left inside the corresponding pressing block grooves on the right support block 26, so that the cargo A pressing block 2708, cargo B pressing block 2709, and cargo C pressing block 2710 extend into their corresponding cargo pressing block positions, thereby locking the support legs of cargo A, cargo B, and cargo C located on the right support block 26. The second lever 2703, through the first link 2711, the second link 2712, and the third link 2713, respectively drives the cargo A pressing block 2708, cargo B pressing block 2709, and cargo C pressing block 2710 to slide to the right inside the corresponding pressing block grooves on the left support block 25. This causes the cargo A pressing block 2708, cargo B pressing block 2709, and cargo C pressing block 2710 to extend into their corresponding cargo pressing block positions, thereby locking the legs of cargo A, cargo B, and cargo C located on the left support block 25.
[0058] When the upper end of any one of the operating handles 2705 is turned to the right, the lower end of the operating handle 2705 is turned to the left, thereby causing the first pull rod 2702 to slide to the right inside the fixed base 2701, and causing the second pull rod 2703 to slide to the left inside the fixed base 2701. This causes the cargo A pressing block 2708, cargo B pressing block 2709, and cargo C pressing block 2710 on the left support block 25 and the right support block 26 to move in the opposite direction and exit from their corresponding cargo pressing block positions, thereby unlocking the legs of cargo A, cargo B, and cargo C located on the left support block 25 and the right support block 26.
[0059] A locking pin 2714 is slidably mounted on the leftmost fixed base 2701, and a locking hole is provided on the second pull rod 2703, with the locking pin 2714 corresponding to the locking hole. When the first pull rod 2702 slides to the left inside the fixed base 2701, and the second pull rod 2703 slides to the right inside the fixed base 2701, goods A, B, and C are locked. At this time, the locking hole corresponds to the locking pin 2714, and the locking pin 2714 is inserted into the locking hole. The second pull rod 2703 can no longer slide, thus locking the locking mechanism 27. When it is necessary to unlock the locking mechanism 27, the locking pin 2714 is pulled out, and the first pull rod 2702 and the second pull rod 2703 can slide again, thereby unlocking the legs of goods A, B, and C.
[0060] The fixed base 2701 includes a base 27011, a connecting base 27012, and a third pin 27013. The connecting base 27012 is fixedly installed at the rear end of the frame 2101 of the front crossbeam 2. The lower end of the base 27011 is snapped into the interior of the connecting base 27012. The base 27011 and the connecting base 27012 are fixed together by the pluggable third pin 27013. The first pull rod 2702 and the second pull rod 2703 are slidably inserted into the interior of the base 27011.
[0061] The working principle of this invention is as follows:
[0062] The crossbeam frame 21 is bolted to the platform base frame 1, and the slide plate 22 is slidably engaged with the two frame guide rails 2102 and fixedly installed by the first pin 23. Figure 16 At position L2, the first magnet 2303 on the first pin 23 is magnetically attracted and fixed to the outer surface of the frame 2101, thus ensuring that the first pin 23 is fixedly connected to the frame 2101 and will not accidentally detach or move axially. The left support block 25 and the right support block 26 are mounted on the corresponding slide plates 22 via the second pin 24. The second handle 2401 of the second pin 24 is magnetically attracted and fixed to the second magnet 2207 on the slide plate 22, thus ensuring that the second pin 24 will not accidentally detach and will not move axially. The locking mechanism 27 is mounted on the frame 2101, and the cargo A pressure block 2708, cargo B pressure block 2709, and cargo C pressure block 2710 slide into the corresponding pressure block grooves of the left support block 25 and the right support block 26, respectively.
[0063] Goods A, B, and C can be arbitrarily hoisted into the left support block 25 and right support block 26 of the front crossbeam 2 and rear crossbeam 3. The cargo pressure blocks inside the left support block 25 and right support block 26 restrict the X and Y degrees of freedom of the cargo legs. Then, by controlling the upper end of any one of the operating handles 2705 to rotate to the left, the cargo A pressure block 2708, cargo B pressure block 2709, and cargo C pressure block 2710 extend into their corresponding cargo pressure block positions, thereby locking the legs of goods A, B, and C located on the left support block 25 and right support block 26. At this time, the locking hole corresponds to the locking pin 2714, and the locking pin 2714 is inserted into the locking hole. At this time, the second pull rod 2703 can no longer slide, thereby completing the locking of the locking mechanism 27, thus restricting the Z-direction freedom of all goods, thereby realizing the mixed loading and quick locking of goods A, B, and C.
[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
