DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-9The present invention provides a technical solution: a public space decorative component flexibly installed steel structure staircase design structure, comprising: a steel structure body 1, a decorative component 2 and a connector 3, the steel structure body 1 comprises a step 11 and an outer baffle 12, a plug socket 111 is arranged on the back of the step 11, a plug cavity is arranged in the plug socket 111, a plug hole 121 corresponding to the plug cavity is arranged on the surface of the outer baffle 12, the height of the plug hole 121 is less than the height of the plug cavity, a connector 3 is arranged on the back of the decorative component 2, the decorative component 2 is plugged into the plug socket 111 through the connector 3, and the connector 3 extends into the plug cavity after passing through the plug hole 121 The connecting member 3 includes a knob 31, a transmission assembly 32, a driving gear 33 and a rack 34. The transmission assembly 32 is arranged in a shell 35 of the connecting member 3. The height of the socket 121 is greater than the height of the shell 35. The transmission assembly 32 is used to drive the driving gear 33. Racks 34 arranged symmetrically on both sides of the driving gear 33 are arranged. The driving gear 33 is meshed with the rack 34. The rack 34 is penetrated by the shell 35. A flexible pad 36 is arranged at the end of the rack 34. The surface of the shell 35 is provided with a step surface for accommodating the flexible pad 36. The rubber coating 4 is clamped on the surface of the shell 35, and the rubber coating 4 contacts the inner wall of the socket 121.

[0038] The transmission assembly 32 includes a first bevel gear 321 and a second bevel gear 322. The knob 31 is sleeved on the first transmission shaft of the first bevel gear 321. The first bevel gear 321 is meshed with the second bevel gear 322. The driving gear 33 is sleeved on the second transmission shaft 3221 of the second bevel gear 322. When the knob 31 is turned, the first bevel gear 321 rotates, the first bevel gear 321 drives the second bevel gear 322 to rotate, and the second bevel gear 322 drives the driving gear 33 to rotate through the second transmission shaft 3221.

[0039] The cross section of the rubber coating 4 is "C"-shaped. The rubber coating 4 is clamped on the housing 35. A first through hole 41 corresponding to the position of the knob 31 is provided on the top surface of the rubber coating 4 to facilitate installation and removal of the rubber coating 4.

[0040] The knob 31 is provided with circumferentially arranged grooves 311 to facilitate the rotation of the knob 31 .

[0041] The side wall of the first through hole 41 is provided with a protrusion 411 whose shape matches the groove 311. The provision of the protrusion 411 enables the rubber coating layer 4 to effectively lock the position of the knob 31 and prevent the knob 31 from rotating, thereby keeping the rack 34 in an open state and ensuring the flexible contact between the flexible pad 36 and the inner wall of the socket 111.

[0042] The flexible pad 36 is a rubber block, which realizes flexible contact with the steel structure body 1 .

[0043] A plurality of plug connectors are arranged on the end surface of the decorative component 2 , and the plug connectors are plugged into grooves on the end surface of another adjacent decorative component 2 .

[0044] The plug connector is hemispherical. Two adjacent decorative components 2 are plugged in through the plug connector to achieve further locking, effectively control the joints, and improve the integrity of the decorative surface composed of the decorative components 2.

[0045] Working principle: When the decorative component 2 is installed, when the connector 3 is not fully inserted into the socket 111, the connector 3 can rotate the driving gear 32 through the bevel gear transmission by turning the knob 31, and the driving gear 32 drives the two racks 33 to extend toward the upper and lower sides of the shell 35, so that the pads 35 at both ends of the connector 3 extend and contact the inner wall of the socket 111. Then, the rubber coating 4 is installed on the surface of the shell 35, and the rubber coating 4 hides the knob 31. After the rubber coating 4 is wrapped around the surface of the shell 35, the height of the connector 3 is equal to the height of the socket 121, and the connector 3 is flexibly in contact with the outer baffle 12 through the rubber coating 4. Continue to push the decorative component 2, the connector 3 is plugged in, and the back of the decorative component 2 contacts the outer baffle 12.

[0046] When the decorative component 2 is installed, the connector 3 is flexibly connected to the steel structure body 1 through the flexible pad 36 made of rubber material and the rubber coating 4, which is easy to install, avoids the vibration of the decorative component 2 caused by the vibration generated by the step 11 when stepping on the stairs, avoids the loose connection of the decorative component 2, effectively controls the noise, and thus effectively controls the joints of the connector 3. The decorative component 2 is easy to install, and even if it is loose, it can be re-tightened. During the plug-in process of the connector 3, the flexible pad 36 extends out of the surface of the shell 35 and contacts the inner wall of the socket 111. On the one hand, the connector 3 can effectively compensate for the socket 111 with an error in the height of the plug-in cavity. On the other hand, when the decorative component 2 falls off, the flexible pad 36 is blocked by the socket 121, effectively preventing the decorative component 2 from falling off and causing safety hazards.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
