DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0036] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, includes: a support seat 2 detachably arranged on the bolt 1, the support seat 2 has a receiving space 210, and the bottom of the support seat 2 has a spherical surface 220; a slide groove 230 is arranged on the support seat 2, the slide groove 230 is connected with the receiving space 210, and the bolt head 1 of the bolt 1 slides in the slide groove 230; a fixed seat 3, the fixed seat 3 has a spherical groove 310, and the spherical groove 310 is hinged to the spherical surface 220.

[0039] In this embodiment, bolt 1 is used to support a corner of the elevated floor. Since the bolt head area of ​​bolt 1 itself is small, if the bolt head is directly used for ground support, the floor itself is not stable and is prone to shaking or collapse. Therefore, support base 2 is used to firmly combine support base 2 with the bolt head. By increasing the ground area of ​​the base, shaking of the device after installation is prevented, and the stability of the device is improved. During the actual installation, there may be local uneven ground. At this time, if support base 2 is used directly, only a small part of the contact with the ground is possible, and the installation may be unstable. By using a ball-hinged connection between fixed base 3 and support base 2, even if the ground is tilted, the angle of fixed base 3 can be adjusted so that fixed base 3 can be adjusted to a suitable height to support the ground, effectively avoiding tilting, improving installation efficiency, and ensuring installation quality.

[0040] As a further technical solution, the invention further includes: a glue bag 4 is arranged in the receiving space 210, and the glue bag 4 contains glue liquid; there are a plurality of glue holes 240, which are arranged on the bottom surface of the support seat 2, and the glue holes 240 are connected with the receiving space 210 and the spherical groove 310;

[0041] In this embodiment, the glue in the glue bag 4 is air-dried glue. Under normal circumstances, the glue is always in a flowing state and will not solidify. Only when the bolt 1 is installed on the support seat 2, the glue bag 4 is squeezed and broken, and the glue will flow out. After the glue flows out and dries, the bolt 1 and the support seat 2 are tightly bonded to ensure that the bolt 1 will not leave the support seat 2. After the glue bag 4 is broken, the glue will also flow out from the glue hole 240 and flow into the spherical groove 310, thereby bonding the ball hinge between the fixing seat 3 and the support seat 2, ensuring the stability of the connection between the support seat 2 and the fixing seat 3, and improving the stability of the bolt 1.

[0042] As a further technical solution, the rubber bag 4 is made of a flexible material and also includes: a support rod 250 is arranged in the rubber hole 240; a conical rod 260 is arranged on the support rod 250, and the sharp end of the conical rod 260 faces the accommodating space 210. After the bolt head of the bolt 1 enters the slide groove 230, the rubber bag 4 is compressed and enters the rubber hole 240, and the conical rod 260 abuts against the rubber bag 4 and punctures the rubber bag 4.

[0043] In this embodiment, the support rod 250 and the conical rod 260 are located inside the glue hole 240. When the bolt 1 enters the slide groove 230, the rubber bag 4 is squeezed and deformed. Part of the rubber bag 4 is squeezed into the glue hole 240, causing the rubber bag 4 to directly contact the conical rod 260, thereby rupturing the rubber bag 4. Through the setting of the conical rod 260, the rubber bag 4 is more likely to rupture, and the material of the rubber bag 4 can use a more flexible material, which prevents the rubber bag 4 from leaking due to poor material quality, thereby improving the safety of the support seat 2.

[0044] As a further technical solution, it also includes: the threaded sleeve 5 is threadedly matched with the bolt 1; the support block 510 is arranged outside the threaded sleeve 5, and the support block 510 is used to cooperate with the threaded sleeve 5 to support the floor.

[0045] In this embodiment, the threaded sleeve 5 plays a major supporting role for the raised floor. The position of the threaded sleeve 5 on the bolt 1 can be adjusted at any time, so by adjusting the position of the threaded sleeve 5, the installation height of the raised floor can be controlled, which facilitates the installation of the floor.

[0046] As a further technical solution, it also includes: the support plate 6 is arranged on the support seat 2, and the support plate 6 abuts against the bottom of the support block 510.

[0047] In this embodiment, the support plate 6 is arranged on the mounting base. Since the elevated floor also has a load-bearing function, only threads are used to support the support base 2. There is a possibility that the threads may fail due to the heavy object, thereby causing damage to the floor. By using the support plate 6 to assist the threads in supporting, the supporting strength of the bolt 1 can be significantly increased, the supporting force of the device can be effectively improved, and the thread failure of the bolt 1 can be prevented.

[0048] As a further technical solution, the support plate 6 has a cavity 610, and also includes: a first mating groove 710 is arranged on the side of the support block 510 close to the support seat 2; the second mating groove 720 is arranged on the side of the support seat 2 close to the support block 510, and the first mating groove 710 and the second mating groove 720 are the same size and are symmetrically arranged; there are several sliding plates 8, which are slidably arranged in the cavity 610. After the sliding plate 8 slides, it forms a limiting space 810 together with the support plate 6, and the bolt 1 is located in the limiting space 810.

[0049] In this embodiment, the first matching groove 710 and the second matching groove 720 jointly limit the support plate 6, ensuring that the support plate 6 will not leave between the support seat 2 and the support block 510 due to sliding, ensuring that the support plate 6 can play a supporting role, and improving the stability of the device. The sliding plate 8 can slide in the first matching groove 710 and the second matching groove 720. After the sliding plate 8 slides, the limiting space 810 can completely wrap the bolt 1, thereby preventing the bolt 1 from leaving the limiting space 810, ensuring that the device can play a role. After the limiting space 810 is formed, by tightening the threaded sleeve 5, the first matching groove 710 and the second matching groove 720 can be further clamped, so that the sliding plate 8 cannot continue to slide, which not only further prevents the bolt 1 from leaving, but also makes the support of the support plate 6 more balanced.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
