[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail this application.

[0024] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0025] As Figure 1 shown, this application provides a steel floor anti-lifting nut adjusting bracket, including a base 1, and at the same time, a support assembly 4 is arranged on the base 1, and this support assembly 4 is used to support the steel floor;

[0026] As Figure 1 shown, the support assembly 4 includes a support column 43 fixedly installed on the base 1, and at the same time, a fixed sleeve 42 is fixedly installed at the end of the support column 43 away from the base 1, and a support plate 41 is fixedly installed on the top of the fixed sleeve 42 to facilitate the installation of the steel floor;

[0027] At the same time, a deployment assembly 3 is arranged on the support assembly 4, and this deployment assembly 3 is used to assist in the support of the steel floor;

[0028] As Figures 1 - 3As shown in the figure, the unfolding component 3 includes a stud 31 rotatably mounted on the base 1. The stud 31 is sleeved outside the support column 43, and two groups of limit rings 32 are fixedly mounted on the stud 31. At the same time, a threaded portion is provided on the stud 31, and this threaded portion is located between the two groups of limit rings 32. At the same time, a sliding sleeve 311 is threadedly mounted on the threaded portion, so as to facilitate rotating the stud 31 to drive the sliding sleeve 311 to move up and down along the axis of the stud 31, and the position of the sliding sleeve 311 is limited by the limit rings 32;

[0029] At the same time, multiple groups of rotating frames 33 are fixedly mounted on the sliding sleeve 311. At the same time, two groups of protective sleeves 37 are fixedly mounted on the rotating frames 33. And two groups of pin columns 39 are penetrated through the inside of the rotating frames 33. The pin columns 39 are slidably arranged inside the protective sleeves 37, and the pin columns 39 have a conical end and a cylindrical end. A spring 38 is connected between the cylindrical end of the pin column 39 and the inside of the protective sleeve 37, so that the conical ends of the two groups of pin columns 39 abut against each other under the action of the spring 38;

[0030] At the same time, multiple groups of concave blocks 36 are hingedly arranged on the fixed sleeve 42 along the circumferential direction. The top of the concave block 36 is fixedly mounted with an auxiliary support plate 35. Thus, the auxiliary support plate 35 can be driven by the concave block 36 to rotate around the hinge point of the concave block 36 and the fixed sleeve 42, so that the auxiliary support plate 35 moves away from or approaches the support plate 41 (refer to Figure 1 and Figure 2 two states);

[0031] At the same time, a connecting rod 34 is hinged at one end of the concave block 36 away from the fixed sleeve 42. At the same time, a through hole (not shown in the figure) is opened at one end of the connecting rod 34 away from the auxiliary support plate 35. It should be noted that in the initial state, the connecting rod 34 is movably sleeved on the two groups of pin columns 39 through the through hole;

[0032] At the same time, two groups of pins 310 penetrate through the rotating frames 33. At the same time, two groups of jacks (not marked in the figure) adapted to the pins 310 are opened at the cylindrical ends of the pin columns 39, so as to facilitate the pins 310 to be inserted into the jacks to limit the states of the two groups of pin columns 39 when they abut against each other and when they retract into the rotating frames 33;

[0033] In the initial state, the auxiliary support plate 35 is in the unfolded state. One end of the connecting rod 34 away from the auxiliary support plate 35 is movably sleeved on the two groups of pin columns 39 through the through hole, and the pins 310 limit the state of the two groups of pin columns 39 when they abut against each other. At this time, the steel floor can be installed;

[0034] When it is necessary to retract the auxiliary support plate 35, rotate the screw rod, thereby driving the sliding sleeve 311 to move downward along the axis of the screw rod, driving multiple groups of rotating frames 33 to move. The rotating frame 33 drives the connecting rod 34 to move through the pin 39, and then drives the concave block 36 on the auxiliary support plate 35 to contract along the hinge point with the fixed sleeve 42;

[0035] When it is necessary to retract the auxiliary support plate 35 at a specific position alone, pull out the pin 310 to release the restriction on the pin 39, and pull the end of the connecting rod 34 away from the auxiliary support plate 35. The end of the connecting rod 34 away from the auxiliary support plate 35 squeezes the conical surface of the pin 39 at this time, causing it to move inward along the axis of the protective sleeve 37 until it separates from the pin 39. Subsequently, the connecting rod 34 is received at the bottom of the concave block 36. At this time, the concave block 36 on the auxiliary support plate 35 is inserted into the rotating frame 33. At this time, the pin 39 repeatedly squeezes into the rotating frame 33, and insert the pin 310 to restrict it to receive the single auxiliary support plate 35;

[0036] In this application, a groove (not marked in the figure) is provided at the bottom of the concave block 36, so that the connecting rod 34 can be received in the groove on the concave block 36.

[0037] At the same time, a locking component 2 is provided on the support assembly 4, and the locking component 2 is used to lock the stud 31 to prevent the stud 31 from loosening;

[0038] As Figures 1 - 2 shown, the locking component 2 includes a screw hole (not shown in the figure) penetrating through the support column 43. In this application, two groups of screw holes are provided, corresponding to the deployment position and the storage position of the auxiliary support plate 35 respectively;

[0039] And a bolt 21 is threadedly installed inside the screw hole. At the same time, a round hole 22 is penetratingly provided on the stud 31, and the bolt 21 is located inside the round hole 22. The screw hole and the round hole 22 are on the same axis, so as to facilitate inserting the bolt 21 into the round hole 22 and screwing it into the screw hole to restrict the rotated stud 31;

[0040] In summary, during use, the steel floor can be supported and fixed by the support plate 41 and the auxiliary support plate 35. When it is necessary to retract the unused auxiliary support plate 35, rotating the screw rod can drive the connecting rod 34 to move through the sliding sleeve 311, and then drive the auxiliary support plate 35 to contract. Finally, the screw rod can be locked by the locking component 2.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
