The embodiments of the present invention will be described in further detail with reference to the following detailed description.

In some embodiments of the present invention, referring to fig. 4 to 6, the number of the elastic claws 22 is at least two, and at least two elastic claws 22 are arranged around the circumference of the supporting seat 21. Taking elastic claws 22 as two examples, two elastic claws 22 are arranged on two opposite sides of the support seat 21, and under the action of external force, if being extruded by the mounting hole 11, the two elastic claws 22 can be close to each other, so that the space occupied by the two elastic claws 22 is reduced, and the elastic claws 22 can pass through the mounting hole 11. After the two elastic claws 22 pass through the mounting holes 11, the extrusion force exerted on the elastic claws 22 by the mounting holes 11 disappears, and the two elastic claws 22 rebound to the open state and are matched with the supporting seat 21, so that the supporting piece 20 is clamped on the connecting piece 10. It should be noted that, the number of the elastic claws 22 can be set according to different requirements, and can be two, three or more, and in the embodiment of the present invention, the number of the elastic claws 22 is not specifically limited.

With continued reference to fig. 5, one way to realize the elastic latch 22 is that one end of the elastic latch 22 is connected to the support seat 21, and the other end extends along the axial direction of the support seat 21 and away from the support seat 21. The side of the elastic claw 22 has a limiting protrusion 221, and the limiting protrusion 221 extends along the radial direction of the support seat 21 in a direction away from the central area of the support seat 21. For supporting seat 21, elasticity jack catch 22 has certain length, can be convenient for elasticity jack catch 22 to wear to establish in mounting hole 11, through spacing protruding 221 increase the thickness of elasticity jack catch 22 for elasticity jack catch 22 is difficult to break away from in the mounting hole 11, makes the block between elasticity jack catch 22 and the mounting hole 11 be connected more stably. Meanwhile, the displacement of the supporting member 20 relative to the connecting member 10 in the up-down direction can be further prevented by the engagement of the limiting protrusion 221 and the supporting seat 21.

Further, in order to make the supporting member 20 more easily pass through the mounting hole 11 to realize clamping, with reference to fig. 5, a side of the limiting protrusion 221 facing away from the central area of the supporting seat 21 is provided with a guiding inclined surface 222, and the thickness of the guiding inclined surface 222 gradually decreases from the second side to the first side. The structure of the limiting protrusion 221 is narrow at the top and wide at the bottom through the guiding slope 222, when the mounting hole 11 is penetrated, the elastic claw 22 firstly extends into the mounting hole 11 through the narrow end, and the mounting hole 11 gradually extrudes the elastic claw 22 along the guiding slope 222, so that the elastic claw 22 is more smoothly clamped into the mounting hole 11. After the elastic claw 22 passes through the mounting hole 11, the wide end of the limiting protrusion 221 is matched with the supporting seat 21, so that the support member 20 and the connecting member 10 are clamped.

The embodiment of the utility model provides an in, mounting hole 11 can be multiple shape according to the demand of difference, and a realizable mode is, and mounting hole 11 is circular structure, and the mounting hole 11 of circular structure makes more easily, can improve preparation efficiency. Another way of realising the mounting hole 11 is that the mounting hole 11 is of a non-circular configuration. The mounting hole 11 is a polygonal structure which is clamped and connected with the elastic clamping jaw 22. If the mounting holes 11 are rectangular or other polygonal shapes, the elastic claws 22 can be correspondingly arranged according to the number of the elastic claws, and the mounting holes 11 with a non-circular structure can prevent the support member 20 from rotating when being connected with a fastener, thereby improving the connection efficiency and improving the connection strength.

Referring to fig. 5 and 6, in order to further enhance the connection strength between the supporting member 20 and the fastening member, in the embodiment of the present invention, a connection nut 30 is disposed in the supporting seat 21, and a screw hole of the connection nut 30 is communicated with the connection hole 23. When coupling assembling 100 is connected on floor carrier plate body 200, support piece 20 accessible coupling nut 30 cooperation fastener is connected with floor carrier plate body 200 to can strengthen the joint strength between fastener coupling nut 30, avoid taking place the dropout condition, can improve joint strength and the degree of reliability between coupling assembling 100 and the fastener, reduce the potential safety hazard. The coupling nut 30 may be disposed in the supporting seat 21 by injection molding, the supporting member 20 includes, but is not limited to, a plastic material and a rubber material, and is formed by injection molding, the elastic claw 22 and the supporting seat 21 are an integral structure, and the coupling nut 30 is injection molded in the supporting seat 21.

Further, for convenience of installation, through holes may be provided in a predetermined position of the floor support plate body 200 in advance, the through holes corresponding to the openings of the connection holes 23, and screws may be connected to the connection holes 23 through the through holes.

When the connecting hole 23 is provided with no connecting nut 30, the embodiment of the present invention provides a connecting method of the fastener and the connecting hole 23, which includes multiple types, and one of the realizable methods is that the connecting hole 23 is a threaded hole matched with the fastener, the fastener can be a screw, and the screw rod of the screw can be directly screwed into the connecting hole 23 to realize the connection. Further, in order to improve the connection strength between the fastening member and the support base 21, the depth of the connection hole 23 is greater than the length of the screw screwed into the connection hole 23, and when the screw is connected with the support base 21, the screw rod of the screw penetrates through the floor support plate body 200 and then extends into the connection hole 23 to be connected with the connection hole 23. If the depth of the screw shaft of the screw extending into the connecting hole 23 is insufficient, the length of the screw for connection is insufficient, so that the connection strength is insufficient. Or, in order to facilitate the use of the screw, the head of the screw is usually thinner than the body of the screw, if the head of the screw is connected with the connecting hole 23, the connecting strength provided by the head of the screw is smaller, if the depth of the connecting hole 23 is greater than the length of the screw screwed into the connecting hole 23, namely, after the screw extends into the connecting hole 23, the screw of the screw completely extends into the connecting hole 23, and the part of the connecting hole 23, which exceeds the screw, provides a containing space for the head of the screw, so that the screw is connected with the connecting hole 23 through the body of the screw, thereby improving the connecting strength.

Another way of connecting the fastener to the connection hole 23 is that the radial dimension of the connection hole 23 is slightly smaller than the radial dimension of the fastener, and the fastener and the connection hole 23 can be connected by interference fit. For example, the fastening member may be a tapping screw, and when the tapping screw is screwed into the connection hole 23, the connection hole 23 is pressed, and the connection hole 23 wraps the tapping screw, thereby achieving connection.
