Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a pre-embedded channel component. Background Technology

[0002] Pre-embedded channel assemblies, as an important connection and fixing device, have wide applications in engineering fields such as construction, bridges, and machinery. They achieve the fixing and support of various equipment and components by pre-installing pre-embedded channels within the structure and then fastening them together with connectors such as T-shaped components.

[0003] However, traditional embedded channel components have some problems and shortcomings in design and use. For example, the connection between the T-shaped component and the embedded channel in some embedded channel components is not stable enough, and it is easy for them to loosen or fall off, thus affecting the stability and safety of the entire structure. In addition, some embedded channel components are complicated to install and disassemble, requiring a lot of time and manpower.

[0004] To address these issues, researchers began researching and developing new types of pre-embedded channel assemblies. One improvement involved adding teeth or other structures to the T-shaped assembly to increase friction with the pre-embedded channel, thereby enhancing the stability of the connection. Simultaneously, various types of fastening nuts and limiting devices were designed to ensure the T-shaped assembly is securely fixed in the pre-embedded channel and to prevent it from loosening or falling off during use.

[0005] Based on this, a pre-embedded channel component is proposed to solve the problem of unstable connection of pre-embedded channel components. Utility Model Content

[0032] Please see Figure 1-6 This utility model provides a technical solution: a pre-embedded channel assembly, including a pre-embedded channel 1.

[0033] like Figure 1 As shown, in some embodiments, the pre-embedded channel 1 includes a pre-embedded channel cavity, in which a T-shaped component 2 is installed. The tail end of the T-shaped component 2 is equipped with a fastening nut 3, which is used to fasten the connection between the T-shaped component 2 and the pre-embedded channel 1 to prevent the T-shaped component 2 from loosening or falling off during use.

[0034] like Figure 1 and Figure 5 As shown, in some embodiments, the T-shaped component 2 includes a T-shaped head 201, a tooth 202, and a threaded rod 203, wherein,

[0035] The second tooth 202 is fixed to both sides of the lower end of the T-shaped head 201. The second tooth 202 is used to increase friction and provide a locking function to ensure the stability of the T-shaped assembly 2 in the pre-embedded channel 1. The threaded rod 203 is fixed to the center below the T-shaped head 201 and is threadedly connected to the fastening nut 3.

[0036] When the fastening nut 3 is rotated, the fastening nut 3 gradually moves along the thread of the threaded rod 203 and generates a fastening force, thereby firmly fixing the T-shaped component 2 in the pre-embedded channel 1.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the pre-embedded channel 1 is provided with a channel opening 101, and the inner side of the channel opening 101 is provided with a tooth 102, which engages with the tooth 202.

[0038] The locking force between the first tooth 102 and the second tooth 202 is increased by the engagement of the two teeth, thereby ensuring the stability and firmness of the T-shaped component 2 in the pre-embedded channel 1.

[0039] like Figure 3As shown, in some embodiments, the fastening nut 3 includes a hexagonal nut 301 and a hexagonal nut 302. The hexagonal nut 301 is fixed below the hexagonal nut 302. The hexagonal nut 301 and the hexagonal nut 302 are concentrically fitted. The diameter of the inscribed circle of the hexagonal nut 301 is larger than the spacing of the channel openings 101. The hexagonal nut 301 is used to abut against the bottom of the pre-embedded channel 1. The diameter of the circumscribed circle of the hexagonal nut 302 is smaller than the spacing of the channel openings 101. The hexagonal nut 302 is used to abut against the bottom of the T-shaped head 201.

[0040] like Figure 4 As shown, in some embodiments, the bottom of the T-shaped head 201 is provided with a groove, and a rotating disk 205 is fitted into the groove with a gap. There is a gap between the rotating disk 205 and the top of the groove. Two rotating plates 2051 are fixed at both ends of the rotating disk 205. The two rotating plates 2051 are symmetrical with respect to the rotating disk 205. Two rotating grooves 206 are provided in the T-shaped head 201. The rotating grooves 206 are fan-shaped. The rotating plates 2051 are disposed in the rotating grooves 206, and the rotating grooves 206 allow the rotating plates 2051 to rotate relative to the rotating disk 205.

[0041] like Figure 4 As shown, in some embodiments, a hexagonal screw hole 204 is provided at the bottom of the rotating disk 205. The minimum diameter of the opening of the hexagonal screw hole 204 is smaller than the outer circle diameter of the hexagonal nut 202, and the maximum diameter of the opening of the hexagonal screw hole 204 is larger than the outer circle diameter of the hexagonal nut 202. Two through holes 211 are also provided in the hexagonal screw hole 204, and the two through holes 211 penetrate the rotating disk 205.

[0042] like Figure 5 and Figure 6 As shown, in some embodiments, the T-shaped head 201 is further provided with two through holes 207, which cooperate with two through holes 211. The top of the T-shaped head 201 is threaded with two screws 208. The two through holes 207 are enlarged with threaded holes, which are threadedly connected to the two screws 208. A spring 209 is fixed below the two screws 208. A limit plate 210 is fixed at the lower end of the spring 209. The limit plate 210 is used to limit the rotation of the hexagonal nut 302.

[0043] Working principle: In the initial state, the screw 208 is screwed into the threaded hole. At this time, the spring 209 inside the through hole 207 is in a compressed state, and the limiting plate 210 abuts against the upper end of the rotating disk 205.

[0044] To prepare for assembly, the second tooth 202 on the T-shaped head 201 is engaged with the first tooth 102 of the pre-embedded channel 1. The engagement design is to ensure that the T-shaped head 201 can be firmly fixed on the pre-embedded channel 1.

[0045] During the tightening process, the fastening nut 3 is screwed into the threaded rod 203, the hexagonal nut 202 abuts against the hexagonal screw hole 204, and drives the rotating disk 205 to rotate.

[0046] The limiting lock is activated when the rotating disk 205 rotates a certain angle and the first through hole 207 and the second through hole 211 coincide. The spring 209 resets, causing the limiting plate 210 to move downwards and abut against the outside of the second hexagonal nut 302, thereby restricting the rotation of the second hexagonal nut 302 and ensuring the stability and robustness of the entire structure. At this time, the first hexagonal nut 301 is precisely abutting below the pre-embedded channel 1.
