[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] Reference Figures 1-7 As shown, a guide rail fixed electrical wiring trough includes: a retaining strip 102 fixedly disposed on the bottom surface of the wiring trough body 100, and a guide rail 101 fixedly disposed on a mounting plate 103 and used in conjunction with the retaining strip 102. The wiring trough body 100 is provided with a mounting mechanism 200 that allows the wiring trough body 100 to be flexibly mounted on or detached from the guide rail 101; wherein,

[0034] The installation mechanism 200 includes: multiple sets of toothed blocks 204 spaced apart on the inner sidewall of the guide rail 101 and a locking block 207 slidably disposed on the bottom wall of the wiring trough body 100 and used in conjunction with the toothed blocks 204.

[0035] During use, ensure that the guide rail 101 is securely fixed to the mounting plate 103. Bring the wiring trough body 100 close to the guide rail 101, aligning the locking strip 102 with the guide rail 101. Slide the wiring trough body 100 to move along the guide rail 101. At this time, the locking block 207 on the bottom wall of the wiring trough body 100 begins to contact the toothed block 204 on the inner side wall of the guide rail 101. As the wiring trough body 100 continues to slide, the locking block 207 begins to slide and find a suitable engagement position under the action of the toothed block 204. When the locking block 207 and the toothed block 204 are fully engaged, the wiring trough body 100 is securely fixed to the guide rail 101. When it is necessary to disassemble the wiring trough body 100, slide the locking block 207 out of the toothed block 204 and slide the wiring trough body 100 to move along the guide rail 101 to the disengaged position. With the design of the mounting mechanism 200, the wiring trunking body 100 can be flexibly mounted on or removed from the guide rail 101 without complicated fixing or disassembly steps, thus improving the convenience of installation and disassembly.

[0036] Reference Figures 5-6 As shown, the mounting mechanism 200 further includes: a fixing block 205, a sliding rod 206, and a driving component; wherein,

[0037] The wiring trough body 100 is rotatably provided with a fixing block 205. The two ends of the fixing block 205 are respectively mirror-fixed with slide rods 206. The sliding end of the slide rod 206 is hinged with a locking block 207. A limiting block 208 is fixedly provided on the locking block 207. The bottom surface of the wiring trough body 100 is provided with a limiting groove 209 for the limiting block 208 to slide. The wiring trough body 100 is also provided with a driving component that drives the fixing block 205 to rotate, thereby driving the locking block 207 to slide.

[0038] In the above scheme, the wiring duct body 100 is aligned with the guide rail 101 in preparation for installation. At this time, the drive component is rotated to keep the locking block 207 in an unengaged state. As the wiring duct body 100 continues to slide, the locking block 207 begins to slide and search for a suitable engagement position under the action of the toothed block 204. Under the action of the drive component, the fixing block 205 is rotated. The rotation of the fixing block 205 drives the slide rod 206 to move, which in turn pushes the locking block 207 to slide within the limiting slide groove 209 through the hinge relationship until the locking block 207 engages with the toothed block 204 on the inner side wall of the guide rail 101.

[0039] Reference Figures 5-6 As shown, the driving component includes: a rotating shaft 201, a turntable 202, and a torsion spring 203; wherein,

[0040] A rotating shaft 201 is rotatably passed through the wiring trough body 100. The fixing block 205 is fixedly installed on the bottom surface of the rotating shaft 201. Therefore, a torsion spring 203 is sleeved on the rotating shaft 201, which abuts against the surface of the fixing block 205 and the bottom surface of the wiring trough body 100.

[0041] In the above scheme, when the wiring duct body 100 needs to be installed, the turntable 202 is manually rotated. The turntable 202 is fixedly connected to the rotating shaft 201, so the rotation of the turntable 202 will drive the rotating shaft 201 and the fixing block 205 to rotate. As the fixing block 205 rotates, the torsion spring 203 begins to bear force and store energy. When the fixing block 205 rotates to a certain angle, the slide rod 206 and the locking block 207 also move until the locking block 207 engages with the toothed block 204 on the inner side wall of the guide rail 101. At this time, the torsion spring 203 is in a stored energy state, providing additional force for the engagement of the locking block 207. When the wiring duct body 100 needs to be disassembled, the turntable 202 is rotated in the opposite direction, causing the fixing block 205 to rotate counterclockwise. The fixing block 205 returns to its initial position, and at the same time, the locking block 207 slides out from the toothed block 204, completing the disassembly.

[0042] Reference Figure 6 As shown, a turntable 202 is fixedly provided at one end of the rotating shaft 201 that passes through the wiring duct body 100.

[0043] In the above scheme, the turntable 202 is manually rotated. One end of the turntable 202 is fixedly connected to the rotating shaft 201. Therefore, rotating the turntable 202 will drive the rotating shaft 201 to rotate together. The wiring duct body 100 can be installed and removed on the guide rail 101 by rotating the turntable 202. No complicated tools or steps are required, which improves the operating efficiency.

[0044] Reference Figures 1-4 As shown, the cross-section of the guide rail 101 is T-shaped, and the cross-section of the clip 102 is L-shaped to match the guide rail 101.

[0045] In the above scheme, the bottom surface of the wiring duct body 100 is placed close to the guide rail 101, so that the L-shaped cross-section of the retaining strip 102 matches the T-shaped cross-section of the guide rail 101. Gently push the wiring duct body 100 so that the retaining strip 102 slides along the T-shaped cross-section of the guide rail 101 and engages. The design of the T-shaped guide rail 101 and the L-shaped retaining strip 102 allows the wiring duct body 100 to be securely mounted on the guide rail 101 while maintaining good adaptability and flexibility.

[0046] Reference Figure 3 As shown, the card strip 102 is provided with a limiting mechanism 300 on the surface perpendicular to the wiring trough body 100 to further limit the wiring trough body 100 on the guide rail 101.

[0047] In the above scheme, after the wiring trough body 100 is initially installed on the guide rail 101, the limiting mechanism 300 is operated to further fix the wiring trough body 100. Through the additional fixation of the limiting mechanism 300, the installation of the wiring trough body 100 on the guide rail 101 is more stable, reducing the risk of loosening caused by vibration or external force.

[0048] Reference Figures 4-8 As shown, the limiting mechanism 300 includes a spring 303 and a limiting block 304; an installation groove 302 is provided on the vertical surface of the locking strip 102, a spring 303 is fixedly installed in the installation groove 302, one end of the spring 303 is fixedly connected to a limiting block 304 that slides with the side wall of the installation groove 302, and a plurality of limiting holes 301 that cooperate with the limiting blocks 304 are spaced apart on the guide rail 101.

[0049] In the above scheme, the sliding wiring trough body 100, under the squeezing action of the side wall of the guide rail 101, the limiting plug 304 overcomes the elastic force of the spring 303 and slides into the mounting groove 302. When the limiting plug 304 is aligned with the designated limiting hole 301 on the guide rail 101, the limiting plug 304 is pushed into the limiting hole 301 under the elastic force of the spring 303, thereby further limiting the wiring trough body 100 on the guide rail 101.

[0050] Reference Figure 4 As shown, the top surface of the limiting insert 304 is arc-shaped.

[0051] In the above scheme, the arc-shaped top surface design makes the limiting plug 304 easier to operate. The limiting plug 304 can be pulled out of the limiting hole 301 by pulling the wiring trough body 100 outward, which facilitates the disassembly of the wiring trough body 100.

[0052] In summary, the guide rail fixed electrical wiring trough provided by this utility model is used by aligning the retaining strip 102 on the bottom surface of the wiring trough body 100 with the T-shaped section of the guide rail 101 and initially placing it on the guide rail 101. At this time, the L-shaped section of the retaining strip 102 is compatible with the guide rail 101, but it is not yet fixed.

[0053] First, the rotating shaft 201 is rotated by the turntable 202, which in turn drives the fixed block 205 to rotate. Since the fixed block 205 has slide rods 206 fixedly mounted at both ends, and the sliding end of the slide rods 206 is hinged to a locking block 207, the rotation of the fixed block 205 will cause the locking block 207 to slide along the slide rods 206. During the sliding of the locking block 207, the limiting block 208 on it slides within the limiting groove 209 on the bottom surface of the wiring duct body 100, ensuring the correct movement trajectory of the locking block 207. When the fixed block 205 rotates to a certain angle, the locking block 207 will engage with the toothed blocks 204 on the inner sidewall of the guide rail 101, that is, the locking block 207 will engage in the gap between the toothed blocks 204, achieving initial fixation. At this time, due to the action of the torsion spring 203, the fixed block 205 will maintain its current position, thus keeping the locking block 207 in a fixed state.

[0054] On the vertical surface of the retaining strip 102, the spring 303 inside the mounting groove 302 pushes the limiting plug 304 to slide outward. When the wiring duct body 100 is fully installed, the arc-shaped top surface of the limiting plug 304 will align with the limiting hole 301 on the guide rail 101. At this time, the thrust of the spring 303 causes the limiting plug 304 to be fully inserted into the limiting hole 301, achieving further fixation.

[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0057] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
