[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model provides mounting blocks on one side of the bottom plate and the layer plate, and utilizes the mounting grooves at both ends of the support rod to cooperate with the mounting blocks to achieve the connection between the bottom plate and the layer plate. The mounting grooves are sleeved on the outside of the mounting blocks to prevent shaking at the connection. At the same time, the locking rod is extended into the locking groove to lock the support rod, making the connection between the bottom plate and the layer plate more stable. The same height of the structural stacking device can be used above the layer plate. Compared with the traditional installation structure, this structure is easy to disassemble and assemble, which can save installation time and improve installation efficiency.

[0018] (2) The utility model provides grooves on both sides of the base plate, and utilizes two threaded rods with opposite threads inside the grooves to drive two threaded blocks to move inside the grooves. The two threaded blocks move toward or away from each other, thereby synchronously driving the support plate and the universal wheel to move closer to or farther away from each other. When the two support plates move away from each other, it is equivalent to expanding the width of the base plate, which can improve the support stability of the device. In this way, after the device is stacked, it can also ensure stability and avoid shaking, thereby effectively improving safety during operation. The two support plates are close to each other, which can reduce the occupied space and facilitate movement. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] See also Figure 1 - Figure 4 As shown, a special protective frame for building main body construction includes:

[0028] A bottom plate 1, a layer plate 11 is movably mounted on the top of the bottom plate 1, a ladder 12 is connected between the bottom plate 1 and the layer plate 11, and four support rods 13 are connected between the bottom plate 1 and the layer plate 11;

[0029] The connecting component 2 is arranged on one side of the support rod 13. The connecting component 2 includes four mounting blocks 21 fixedly installed on one side of the bottom plate 1. Four mounting blocks 21 are also fixedly installed on both sides of the layer plate 11. The support rod 13 is provided with a mounting groove 22 at one end close to the mounting block 21. The mounting groove 22 is arranged corresponding to the mounting block 21. The support rod 13 is provided with a locking rod 26 movably installed on one side close to the mounting groove 22.

[0030] The stabilizing component 3 is arranged on both sides of the base plate 1. The stabilizing component 3 includes grooves 31 opened on both sides of the base plate 1. Two threaded blocks 33 are movably installed inside the grooves 31. One side of the two threaded blocks 33 is fixedly connected to a support plate 34. One side of the support plate 34 is movably installed with a universal wheel 35.

[0031] Specifically, the mounting block 21 is slidably fitted inside the mounting groove 22, a locking hole 23 is opened on one side of the mounting block 21, a U-shaped plate 24 is fixedly installed on the side of the support rod 13 close to the mounting groove 22, a baffle 25 is fixedly installed inside the U-shaped plate 24, a locking rod 26 is movably installed between the baffle 25 and the U-shaped plate 24 through the opening, one end of the locking rod 26 passes through the inside of the mounting groove 22, the locking rod 26 is arranged corresponding to the locking hole 23, the locking rod 26 extends into the locking hole 23, the locking rod 26 is slidably fitted with the inner wall of the locking hole 23, a reset plate 27 is fixedly installed on the outside of the locking rod 26, two reset springs 28 are connected between the reset plate 27 and the inner wall of the U-shaped plate 24, and the two reset springs 28 are symmetrically arranged on both sides of the reset plate 27.

[0032] As can be seen from the above, the ladder 12 is installed using existing technology, and the mounting groove 22 is sleeved on the outside of the mounting block 21. At this time, the support rod 13 can connect the base plate 1 with the layer plate 11, and at the same time, the locking rod 26 is extended into the locking hole 23 to ensure the stability of the connection. The reset plate 27 and the reset spring 28 can drive the locking rod 26 to complete the reset.

[0033] During specific use, first pull the locking rod 26 to move the locking rod 26 away from the mounting groove 22. At this time, the reset spring 28 is in a compressed state. Then, the mounting groove 22 is sleeved on the outside of the mounting block 21. Then, release the locking rod 26. The locking rod 26 will extend into the locking hole 23 under the action of the reset spring 28 to complete the installation.

[0034] Embodiment 2:

[0035] See also Figure 1 and Figure 5As shown, two grooves 31 are opened on the side of the base plate 1 away from the mounting block 21, and the two grooves 31 are symmetrically arranged. Two threaded rods 32 are movably installed inside the two grooves 31 through bearings. The two threaded rods 32 are fixedly connected, and the outer threads of the two threaded rods 32 are opposite. The outer sides of the two threaded rods 32 are screwed with threaded blocks 33.

[0036] Specifically, a support plate 34 is fixedly installed on the side of the threaded block 33 away from the groove 31, a universal wheel 35 is movably installed on one side of the support plate 34 through a bearing, a driven bevel gear 36 is fixedly installed at the connection between the two threaded rods 32, a driving bevel gear 37 is movably installed on the side of the groove 31 close to the driven bevel gear 36 through a bearing, the driving bevel gear 37 is meshed with the driven bevel gear 36, and a handwheel 38 is movably installed on the side of the base plate 1 close to the groove 31, and the handwheel 38 is connected to the shaft of the driving bevel gear 37 through transmission.

[0037] As can be seen from the above, since the outer threads of the two threaded rods 32 are opposite, when the threaded rod 32 rotates, the two threaded blocks 33 will move towards or away from each other inside the groove 31, thereby synchronously driving the support plate 34 to move, and the active bevel gear 37 cooperates with the driven bevel gear 36 to achieve that the threaded rod 32 can be driven to rotate by turning the handwheel 38 on the outside.

[0038] When in use, the hand wheel 38 is first turned, and the hand wheel 38 drives the active bevel gear 37 to rotate, and then the active bevel gear 37 will synchronously drive the driven bevel gear 36 to rotate, thereby driving the threaded rod 32 to rotate, and then the two threaded blocks 33 move away from each other and push the support plate 34 to move. When the two support plates 34 move away from each other, it is equivalent to expanding the width of the base plate 1, which can improve the support stability of the device, so that stability can be guaranteed after the device is stacked high.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
