Description

Technical Field

[0001] The present invention relates to a wiring duct installation structure, belonging to the field of wiring duct installation. Background Art

[0002] According to relevant decoration design specifications and other requirements, a certain spacing should be left between the wiring duct in the office area and the ground to form an overhead structure. Therefore, support feet are usually provided at the bottom of the wiring duct. For traditional wiring ducts, they are first fixed to the cover plate by screws, and then installed on the support feet by screws. Therefore, two screw operations are required. The same wiring duct may be connected with multiple cover plates and support feet, which sharply increases the number of screw operations. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a wiring duct installation structure.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A wiring duct installation structure includes a wiring duct, support feet, and a cover plate. The top edge of the wiring duct bends towards the outside of the wiring duct to form a card slot with the opening facing downwards. The support feet include an overhead rod and a support plate installed on the overhead rod. The edge of the support plate bends upwards to form a clamping plate, and the top edge of the clamping plate is clamped in the card slot. The edge of the cover plate bends downwards to form an expansion plate, and the bottom edge of the expansion plate extends towards the middle of the cover plate to form a positioning plate. The edge of the positioning plate fits against the bottom of the clamping plate, and the positioning plate presses on the support plate.

[0006] The beneficial effects of the present invention are as follows:

[0007] The overhead rod makes the support plate suspended, and the clamping plate can be clamped into the card slot to complete the installation of the wiring duct on the support plate, simplifying the installation process between the wiring duct and the support feet. Since the opening of the card slot faces downwards, under the action of gravity, the clamping plate can naturally support the inner wall of the card slot without falling out of the card slot, ensuring the support stability of the support feet for the wiring duct. The cover plate is connected to the support plate through the expansion plate, thereby obtaining the support effect of the support plate. Therefore, the cover plate and the wiring duct form an integral structure through the support plate, and after the cover plate is supported, it can further support the decorative panel installed subsequently. The expansion plate lifts the cover plate under the condition of avoiding the side wall of the wiring duct, increasing the distance between the cover plate and the inner wall of the bottom of the wiring duct, so that the cover plate is located above the wiring duct, thereby covering the top opening of the wiring duct. The increase in the distance between the cover plate and the inner wall of the bottom of the wiring duct also further increases the space for wiring.

[0008] The support plate of the present invention is provided with locking holes, and the positioning plate is provided with locking grooves. The locking grooves extend along the axial direction of the wire groove, and the locking holes communicate with the locking grooves. A locking screw is arranged at the locking holes, and the locking screw locks the positioning plate on the support plate.

[0009] An assembly and disassembly notch is formed at the edge of the cover plate of the present invention, and the assembly and disassembly notch and the locking hole are opposite in the direction perpendicular to the support plate.

[0010] The assembly and disassembly notch of the present invention is located at the end of the cover plate, and the end of the positioning plate is located in the middle of the support plate.

[0011] An adjusting nut is threadedly connected to the overhead rod of the present invention. The support plate is located above the adjusting nut, and the adjusting nut supports the support plate.

[0012] Both the expansion plate and the positioning plate of the present invention are located between the two ends of the cover plate.

[0013] The present invention further includes an overhead plate. The edge of the overhead plate is supported on the support plate so that the upper surface of the overhead plate and the upper surface of the cover plate are in the same plane.

[0014] On the side of the support plate opposite to the clamping plate, the edge extends upward to form a limiting plate. A limiting rod is fixed to the bottom edge of the overhead plate. The limiting rod presses on the support plate, and the support plate supports the overhead plate through the limiting rod. The limiting rod fits on the limiting plate so that the edge side wall of the overhead plate fits with the expansion plate.

[0015] The upper end of the overhead rod of the present invention is located above the support plate. An avoidance groove is formed on the outer wall of the limiting rod on the side close to the upper end of the overhead rod. The upper end of the overhead rod is located in the avoidance groove and there is a gap between the upper end of the overhead rod and the inner wall of the avoidance groove.

[0016] The cross-sectional shape of the limiting rod of the present invention is rectangular.

[0017] Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0028] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating orientation or position relationship are only for convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0029] Embodiment:

[0030] Refer to Figure 1-8 , the wire trough installation structure provided in this embodiment includes an overhead board 4, a wire trough 1, support feet 2, and a cover plate 3. The wire trough 1 is located between two adjacent overhead boards 4. Both the wire trough 1 and the overhead board 4 are supported by the support feet 2 to be separated from the ground, thereby forming an overhead structure to meet the decoration specifications of the office area. The cover plate 3 covers the opening at the top of the wire trough 1 to protect the wires in the wire trough 1. After the cover plate 3 is installed, the upper surface of the cover plate 3 and the upper surface of the overhead board 4 should be in the same horizontal plane to facilitate the installation of the decorative panel and ensure that the decorative panel remains horizontal.

[0031] Both sides of the top edge of the wire trough 1 are bent towards the outside of the wire trough 1 to form a clamping groove 11, and the opening of the clamping groove 11 faces downward. Since both sides of the wire trough 1 are supported by the support feet 2, the wire trough 1 is a symmetric structure. Taking the installation relationship between one side of the wire trough 1 and the support feet 2 as an example for illustration.

[0032] The support foot 2 includes a bottom plate 24, an overhead pole 21, and a support plate 22 mounted on the overhead pole 21. The lower end of the overhead pole 21 is fixed in the middle of the bottom plate 24. The bottom plate 24 is in contact with the ground to ensure the contact area between the single support foot 2 and the ground, and to ensure the support stability of the support foot 2 to the overhead plate 4 and the wiring trough 1. The support plate 22 and the bottom plate 24 are parallel, so the support plate 22 is also roughly in a horizontal state. One side edge of the support plate 22 is bent upward to form a card plate 221. The edge of the support plate 22 on the side opposite to the card plate 221 extends upward to form a limit plate 222. In this embodiment, the card plate 221 and the limit plate 222 are both roughly in a vertical state.

[0033] The width of the card slot 11 and the thickness of the card plate 221 are roughly equal, so the top edge of the card plate 221 can be snapped into the card slot 11 to complete the installation of the wiring trough 1 on the support foot 2. As long as both sides of the wiring trough 1 are installed on the support foot 2, the wiring trough 1 can obtain stable support. Since the opening of the card slot 11 faces downward, the top edge of the card plate 221 can naturally support the inner wall of the card slot 11 under the action of gravity, and will not easily detach from the card slot 11. Therefore, even if the thickness of the card plate 221 is slightly smaller than the width of the card slot 11, it can fully ensure the support stability of the support foot 2 on the wiring trough 1.

[0034] The edges of both sides of the cover plate 3 are bent downward to form an expansion plate 31, and the bottom edge of the expansion plate 31 extends toward the middle of the cover plate 3 to form a positioning plate 32. Under the avoidance effect of the expansion plate 31 on the side wall of the wiring trough 1, the positioning plate 32 can be pressed on the support plate 22 under the action of gravity, so that the support foot 2 can support the cover plate 3. The bottom of the card plate 221 is located below the card slot 11, and the connection between the cover plate 3 and the expansion plate 31 is deformed, so that the positioning plate 32 can be stretched to the outside of the cover plate 3, so that when the cover plate 3 is covered to the top opening of the wiring trough 1, the positioning plate 32 passes over the card slot 11 to reach the bottom of the card plate 221. When the positioning plate 32 is pressed on the support plate 22, the edges of the two positioning plates 32 on both sides of the cover plate 3 are respectively attached to the bottom of the corresponding card plate 221, and the bottom of the card plate 221 is used to position the final installation position of the cover plate 3. The cover plate 3 can only be adjusted along the axial direction of the wiring trough 1.

[0035] The cover plate 3 and the wiring trough 1 are connected by the support legs 2. The support legs 2, the cover plate 3 and the wiring trough 1 form an integral structure. During this process, no operations such as nailing are required, which makes the installation simple and improves the installation efficiency, while also ensuring the stability of the overhead structure.

[0036] It should be noted that in addition to avoiding the side wall of the wire groove 1 so that the positioning plate 32 is supported on the support plate 22, the expansion plate 31 also raises the height of the cover plate 3 on the support plate 22, so that the cover plate 3 is located above the wire groove 1, ensuring the covering effect of the cover plate 3 on the wire groove 1. Further, the expansion plate 31 also makes the cover plate 3 higher than the top edge of the wire groove 1, increasing the distance between the cover plate 3 and the inner wall of the bottom of the wire groove 1. Therefore, the wire routing space is jointly enclosed by the cover plate 3, the expansion plate 31 and the wire groove 1. Compared with the case where the wire routing space is only enclosed by the cover plate 3 and the wire groove 1, the wire routing space is increased.

[0037] The length of the cover plate 3 is generally less than that of the wire groove 1. Therefore, multiple cover plates 3 are usually installed on the wire groove 1. It is necessary to position the axial position of the cover plate 3 on the wire groove 1 in order to lay the decorative panel above the cover plate 3. Based on this, locking holes are provided on the support plate 22, and locking grooves 321 are provided on the positioning plate 32. The locking grooves 321 extend along the axial direction of the wire groove 1. The locking holes and the locking grooves 321 are communicated, and locking screws 223 are arranged in the locking holes in a threaded manner. After the locking screws 223 are locked, their ends can lock the positioning plate 32 on the support plate 22. After the locking screws 223 are unlocked, the cover plate 3 can move axially.

[0038] The locking and unlocking of the locking screws 223 are carried out when the cover plate 3 is covered above the wire groove 1. In order to facilitate the operation of the locking screws 223, disassembly and assembly notches 33 are provided at the edge of the cover plate 3. The disassembly and assembly notches 33 and the locking holes are opposite in the direction perpendicular to the support plate 22. Correspondingly, the disassembly and assembly notches 33 and the locking screws 223 are opposite in the direction perpendicular to the support plate 22. Therefore, a screwdriver can directly operate and control the locking screws 223 through the disassembly and assembly notches 33. The disassembly and assembly notches 33 can also be used as an observation port to observe the wire routing situation in the wire groove 1. The disassembly and assembly notches 33 also save the material usage of the cover plate 3, thereby reducing the production cost of the cover plate 3.

[0039] Preferably, the disassembly and assembly notches 33 are located at the ends of the cover plate 3 to facilitate the opening of the disassembly and assembly notches 33. At the same time, the disassembly and assembly notches 33 at the ends of adjacent cover plates 3 can be spliced with each other to form a larger space for the screwdriver to move. This moving space can facilitate the disassembly and assembly of adjacent cover plates 3 by the screwdriver. Therefore, in this embodiment, the end of the positioning plate 32 is located in the middle of the support plate 22. Therefore, the same support plate 22 can support adjacent cover plates 3 at the same time. On the one hand, the number of support feet 2 is reduced, and on the other hand, the splicing effect and stability of adjacent cover plates 3 are ensured, avoiding the relative movement between the cover plates 3.

[0040] In this embodiment, two adjacent cover plates 3 and the wire trough 1 are both installed on the same support plate 22. Therefore, the support plate 22 can drive two adjacent cover plates 3 and the wire trough 1 to lift synchronously, and the covering effect of the cover plate 3 on the wire trough 1 will not be affected during the lifting process of the support plate 22.

[0041] Specifically, an adjusting nut 23 is threadedly connected to the overhead pole 21. The support plate 22 is located above the adjusting nut 23, and the adjusting nut 23 supports the support plate 22. By rotating the adjusting nut 23, the adjusting nut 23 can drive the support plate 22 to lift along the axial direction of the overhead pole 21. A relief hole is provided at the center of the support plate 22, and the overhead pole 21 passes through the support plate 22 through the relief hole. There is a gap between the overhead pole 21 and the relief hole to prevent the thread on the outer wall of the overhead pole 21 from affecting the lifting of the support plate 22.

[0042] On this basis, both ends of the expansion plate 31 and both ends of the positioning plate 32 of this embodiment are located between both ends of the cover plate 3. After two adjacent cover plates 3 are spliced, there will be a certain gap between the ends of two adjacent expansion plates 31 and between the ends of two adjacent positioning plates 32. This gap enables the cover plate 3 to avoid the overhead pole 21 at the center of the support plate 22, and at the same time, this gap will also penetrate to the disassembly notch 33, further expanding the movement space of the screwdriver.

[0043] Regarding the overhead plate 4, its edge is also supported on the support plate 22, so as to realize that a single support foot 2 supports the adjacent wire trough 1 and the overhead plate 4 at the same time. On the basis of reducing the number of support feet 2 used, ensure the relative position stability between the wire trough 1 and the overhead plate 4 as much as possible, so as to ensure the installation stability of the decorative panel. The lifting of the support plate 22 can drive the wire trough 1 and the overhead plate 4 to lift synchronously, avoiding the vertical height misalignment between the wire trough 1 and the overhead plate 4, and ensuring that the upper surface of the overhead plate 4 and the upper surface of the cover plate 3 can always be in the same plane.

[0044] A limiting rod 41 is fixed to the bottom edge of the overhead plate 4. The limiting rod 41 presses on the support plate 22, and the support plate 22 supports the overhead plate 4 through the limiting rod 41. The limiting rod 41 indirectly raises the height of the overhead plate 4, so as to match the height of the expansion plate 31, and ensure that the upper surface of the overhead plate 4 and the upper surface of the cover plate 3 are in the same horizontal plane without increasing the thickness of the overhead plate 4.

[0045] The limiting rod 41 is attached to the limiting plate 222, and the installation position of the limiting rod 41 on the support plate 22 is positioned through the limiting plate 222, so that the edge side wall of the overhead plate 4 fits with the expansion plate 31, minimizing the distance between the overhead plate 4 and the wire trough 1 as much as possible, so as to ensure the support effect received by the decorative panel. After the positioning of the limiting rod 41 is completed, the limiting rod 41 can be fixed to the support plate 22 with screws.

[0046] Preferably, the cross-sectional shape of the limiting rod 41 is rectangular. On the one hand, the contact surface between the limiting rod 41 and the support plate 22 is enlarged, improving the support stability of the support plate 22 for the limiting rod 41. On the other hand, the contact area between the limiting rod 41 and the limiting plate 222 can also be relatively large to ensure the positioning effect of the limiting plate 222 on the limiting rod 41. In addition, there can also be a good fitting effect between the limiting rod 41 and the expansion plate 31, minimizing the damage of the limiting rod 41 to the expansion plate 31 as much as possible.

[0047] To ensure that the support plate 22 has a certain lifting margin, the upper end of the overhead rod 21 is usually located above the support plate 22. An avoidance groove 411 is formed in the outer wall of the limiting rod 41 on the side close to the upper end of the overhead rod 21. The upper end of the overhead rod 21 is located in the avoidance groove 411 and there is a gap between it and the inner wall of the avoidance groove 411 to ensure the avoidance effect of the limiting rod 41 on the overhead rod 21 during the lifting process of the support plate 22. Therefore, the height adjustment of the support plate 22 can be carried out before and after the installation of the overhead plate 4.
