Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to a cable duct and an installation method thereof. Background Art

[0002] Cable troughs are important components for cable installation and protection in electrical cabinets. They can effectively protect cables from damage and improve the aesthetics of the cabinet. Commonly used materials are metal and plastic. Metal cable troughs have better mechanical strength and rigidity than plastic cable troughs, are not easily damaged or deformed, and have the advantage of preventing electromagnetic interference, so they are widely used in the electrical industry.

[0003] The structure of the metal cable laying trough mainly consists of two parts: the trough body and the trough cover. The trough body is used to carry the cables. After the cables are laid in the trough body, the trough cover is put on to completely protect the cables in the cable laying trough, forming a physical isolation from the outside. The trough body and trough cover of the traditional metal cable laying trough are connected by bolts on both sides of the trough body and the trough cover. Both sides need to reserve space for personnel operation, and both sides cannot be blocked. This places high requirements on the cabinet and affects the system integration. When connecting, the nuts on both sides need to be installed one by one, which is time-consuming, and there is a risk of the nuts loosening and falling during installation, disassembly and transportation.

[0004] In order to improve the stability of the trough body and the trough cover and the convenience of installation, the prior art discloses a solution for realizing the rapid installation of the trough cover and the trough body by moving the elastic component on the trough body while ensuring the installation stability. However, during installation, it is necessary to manually pull or slide the pull plate or slider connected to the elastic member to compress or stretch the elastic member so that the trough cover and the trough body can be smoothly installed and fixed. Therefore, there is still the problem of inconvenient installation. Summary of the invention

[0005] In view of this, the present invention provides a wire trough and an installation method thereof to solve the problem of inconvenient installation of the wire trough in the prior art.

When the elastic locking member is in the first and second states, the elastic member releases potential energy to fix the cover plate and the trough body.

[0009] Optionally, the first locking hole is a long hole arranged along the length direction of the cable, and when the first locking piece is engaged in the first locking hole, the cover plate can move along the length direction of the cable.

[0010] Optionally, a second locking component is provided on a side of the slot body away from the first elastic locking component, and the second locking component is suitable for limiting the relative displacement of the slot body and the cover plate.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] If the defects of the prior art are not described in detail in the background technology section, the defects of the prior art are analyzed in detail here to introduce this solution.

[0023] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0024] According to an embodiment of the present invention, on the one hand, a wire duct is provided, comprising: A tank body 1, with a notch formed thereon, comprising a bottom plate 11 and two first side plates 12 disposed on both sides of the bottom plate 11; The cover plate 2 is covered on the notch to form a cable accommodation space. The cover plate 2 includes a top plate 21 and two second side plates 22 arranged on both sides of the top plate 21. The second side plates 22 are arranged at an angle with the top plate 21. When the cover plate 2 is covered on the notch, the two second side plates 22 respectively cover at least a portion of the corresponding first side plate 12; At least one set of first elastic locking components is arranged on the covering surfaces of the first side plate 12 and the second side plate 22, and has a first state of compressing and storing energy when the cover plate 2 covers the slot and a second state of releasing energy when the cover plate 2 covers the slot, so that the cover plate 2 and the slot body 1 are fixed.

[0025] It is easy to understand that the angle setting in this wire trough refers to the intersection setting between the top plate 21 of the cover plate 2 and the second side plates 22 arranged on both sides of the top plate 21 at a certain angle. In this embodiment, the second side plates 22 on both sides are parallel to each other and perpendicular to the top plate 21. Such a setting can better cooperate with the first side plate 12 of the trough body 1. The two second side plates 22 respectively cover at least a part of the corresponding first side plate 12, making the covering more compact and stable, increasing the overall structural strength and stability of the wire trough, and effectively preventing the wire trough from deformation or loosening during use.

[0026] Specifically, the second side panel 22 covers the upper side of the corresponding first side panel 12, and the coverage degree thereof can be selected and set according to actual conditions, and is not limited here.

[0027] It should be noted that the number of first elastic locking components can be set according to the length of the wire trough. Here, there is no restriction on the specific number of first elastic locking components. And the setting positions can be reasonably distributed along the length direction according to the specific length of the wire trough. For example, the first elastic locking components can be set on one side, and one or more first elastic locking components can be set according to the length of the wire trough. Here, there is no restriction on the specific setting method.

[0028] It should be noted that when the first elastic locking component is in the second state, its elastic potential energy is not completely released, but a certain stretching will be generated compared to the first state, so as to ensure the stability of the fixation of the trough body 1 and the cover plate 2.

[0029] The cable trough provided in an embodiment of the present invention comprises a trough body 1, which is provided with a notch, the trough body 1 comprising a bottom plate 11 and two first side plates 12 arranged on both sides of the bottom plate 11; a cover plate 2, the cover plate 2 is covered on the notch to form a cable accommodating space, the cover plate 2 comprises a top plate 21 and two second side plates 22 arranged on both sides of the top plate 21, the second side plates 22 are arranged at an angle to the top plate 21, when the cover plate 2 is covered on the notch, the two second side plates 22 respectively cover at least a part of the corresponding first side plate 12; at least one group of first elastic locking components is provided on the covering surfaces of the first side plate 12 and the second side plate 22, and has a first state of compressing and storing energy when the cover plate 2 covers the notch and a second state of releasing energy when the cover plate 2 is covered on the notch, so that the cover plate 2 and the trough body 1 are fixed.

[0030] Compared with the traditional cable duct connection method, this cable duct does not need to reserve space for personnel operation on both sides, has lower requirements for the cabinet, and improves the integration of the system. Whether in a small space or in a complex installation environment, the installation of the cable duct can be easily completed. And the installation process is relatively simple. When the cover plate 2 covers the notch, the elastic locking component automatically enters the first state to compress and store energy, and can be assembled without additional tools or complicated operating steps. When the cover plate 2 is covered on the notch, the elastic locking component switches to the second state to release energy, achieving rapid fixation, greatly improving installation efficiency.

[0031] The first elastic locking component in the cable trough provided by the embodiment of the present invention further enhances the fixing effect of the cover plate 2 and the trough body 1. In the first state, the elastic locking component is compressed to store energy, providing a certain buffer for the installation of the cover plate 2; in the second state, the first elastic locking component releases energy so that the cover plate 2 and the trough body 1 are firmly fixed together, and even in the case of external vibration or impact, the cover plate 2 and the trough body 1 will not loosen or fall off, further ensuring the safety of the cables in the cable trough.

[0032] Further, the first elastic locking assembly comprises: A first locking member 31 is disposed on a covering surface of the first side plate 12 corresponding to the second side plate 22; A first locking hole 32 is formed on the second side plate 22 , and the first locking member 31 is adapted to be snapped into the first locking hole 32 ; The elastic locking piece 33 has one end connected to the first side plate 12 and the other end abutting against the second side plate 22 . The elastic locking piece 33 can be elastically deformed along its axial direction under the action of external force.

[0033] It is easy to understand that the natural state refers to the state of the first elastic locking component when it is not subjected to external force. In order to ensure that the trough body 1 and the cover plate 2 are firmly covered, the length of the first locking member 31 needs to be set greater than the length of the elastic locking member 33.

[0034] It is easy to understand that the clamping design of the first locking member 31 and the first locking hole 32 makes the connection between the cover plate 2 and the trough body 1 more secure. The clamping method can provide a stable fixing force to prevent the cover plate 2 from accidentally opening during use, thereby ensuring the safety of the cables. The elastic locking member 33 is arranged between the first side plate 12 and the second side plate 22, and its elastic force ensures a stable connection between the cover plate 2 and the trough body 1, further enhancing the structural stability of the cable trough.

[0035] Furthermore, the elastic locking member 33 comprises: A first end plate 331 is disposed on the first side plate 12; A connecting rod 332, a first end of which is disposed on a side of the first end plate 331 away from the first side plate 12 and is spaced apart from the first end plate 331; The bearing cylinder 333 has a through hole along its axial direction. The bearing cylinder 333 is sleeved on the connecting rod 332. The connecting rod 332 can move relative to the bearing cylinder 333. One end surface of the bearing cylinder 333 is connected to the first end plate 331. The second end of the connecting rod 332 is exposed at the other end surface of the bearing cylinder 333. A second end plate 334 is disposed on the second end of the connecting rod 332, and an end surface of the second end plate 334 away from the connecting rod 332 abuts against the second side plate 22; The elastic member 335 is sleeved on the bearing cylinder 333. The length of the elastic member 335 in a natural state is greater than the axial length of the bearing cylinder 333. One end of the elastic member 335 is connected to the second end plate 334, and the other end is connected to the first end plate 331. When the elastic locking member 33 is in the first state, the elastic member 335 undergoes compression elastic deformation, causing the first end of the connecting rod 332 to move toward the first end plate 331, and the second end plate 334 abuts against the second side plate 22. When the elastic locking member 33 is in the first and second states, the elastic member 335 releases potential energy to fix the cover plate 2 and the slot body 1.

[0036] It is easy to understand that the first end plate 331 is arranged on the first side plate 12, providing a solid foundation for the entire locking member. The first end plate 331 and the first side plate 12 can be connected by welding, riveting or bolting, etc., to ensure the stability and reliability of the connection.

[0037] It is easy to understand that the connecting rod 332 plays a guiding role and can withstand the pressure when the cover plate 2 is closed and the elastic force of the elastic member 335. Here, the specific material of the connecting rod 332 is not limited.

[0038] It is easy to understand that the bearing cylinder 333 provides an installation space for the elastic member 335, and also plays a role in limiting the movement direction of the elastic member 335. The length of the elastic member 335 in the natural state is greater than the axial length of the bearing cylinder 333, thereby providing a certain compression space when the cover plate 2 and the tank body 1 are covered, so that the other side of the cover plate 2 can be smoothly covered on the other side of the tank body 1.

[0039] It should be noted that when the elastic member 335 is compressed and elastically deformed, and the first end of the connecting rod 332 moves toward the first end plate 331, the connecting rod 332 and the first end plate 331 do not abut, and there is a gap between the connecting rod 332 and the first end plate 331 to ensure that there is a certain deformation margin when the elastic locking member 33 is compressed in the first state, so that the elastic member 335 can deform more smoothly when subjected to force. This helps to maintain the stability of the device during operation. And when the elastic locking member 33 needs to be adjusted or maintained, the existence of the gap makes the operation more convenient. The staff can more easily observe the state of the elastic member and determine whether it needs to be replaced or adjusted.

[0040] It is easy to understand that the second end plate 334 is arranged on the second end of the connecting rod 332, which further enhances the stability of the first elastic locking assembly. The second end plate 334 can play a role of limiting when the cover plate 2 is closed. One end of the elastic member 335 is connected to the second end plate 334, and the other end is connected to the first end plate 331.

[0041] It should be noted that in the present embodiment, the elastic member 335 is a spring having good elasticity and stability and can provide a large elastic force. Coil springs of different wire diameters, numbers of turns and materials can be selected as needed to meet different locking force requirements. Coil springs are easy to install and are suitable for wire ducts of various sizes. In other embodiments, the elastic member 335 can be a spring sheet, which is made of a metal sheet and has a high elastic modulus and strength. The spring sheet can provide a large elastic force and takes up less space, and is suitable for wire ducts with limited space.

[0042] Furthermore, a locking piece is provided on the first end of the connecting rod 332, and the end surface of the locking piece is larger than the through hole diameter of the bearing cylinder 333, so as to prevent the elastic member 335 from releasing elastic potential energy to eject the connecting rod 332 from the bearing cylinder 333 when the cover plate 2 is removed from the tank body 1, thereby improving the structural stability. Here, the specific setting form of the locking piece is not limited, and in actual production, the locking piece can be set to a circular piece or a polygonal piece according to production needs.

[0043] In an optional embodiment, the locking plate can be replaced by a locking piece, which can be set as a sphere or a prism, but this setting will shorten the movement stroke of the connecting rod 332 in the supporting cylinder 333. In actual production, it can be selected according to the needs of the cable trough installation and is not limited here.

[0044] Furthermore, a receiving cavity is provided inside the bearing cylinder 333 , and the receiving cavity is communicated with the through hole.

[0045] It should be noted that the second end of the connecting rod 332 can pass through the through hole, so that the second end of the connecting rod 332 is exposed on one side of the through hole of the bearing cylinder 333 and connected to the second end plate 334, and the first end of the connecting rod 332 and part thereof move in the accommodating cavity under the elastic action of the elastic member 335. Of course, in order to ensure the normal use of the connecting rod 332, the diameter of its accommodating cavity needs to be larger than the diameter of the through hole, thereby ensuring that the locking piece can move smoothly in the accommodating cavity.

[0046] Furthermore, the first locking hole 32 is a long hole arranged along the length direction of the cable. When the first locking member 31 is engaged in the first locking hole 32 , the cover plate 2 can move along the length direction of the cable.

[0047] It is easy to understand that the first locking hole 32 with a long hole design allows the cover plate 2 to move along the length direction of the cable, and can achieve fine-tuning of the position of the cover plate 2 to better adapt to different installation environments and cable layouts. In the actual installation process, there may be some installation errors. The first locking hole 32 with a long hole design can compensate for these errors to a certain extent, so that the cover plate 2 can still fit closely with the trough body 1 after installation, ensuring the overall performance of the cable trough and improving the flexibility and convenience of installation.

[0048] Furthermore, a second locking component is provided on a side of the trough body 1 away from the first elastic locking component, and the second locking component is suitable for limiting the relative displacement between the trough body 1 and the cover plate 2 .

[0049] It is easy to understand that the second locking component is arranged on the side of the trough body 1 away from the first elastic locking component, which can work together with the first elastic locking component to fix the trough body 1 and the cover plate 2 from both sides, thereby enhancing the overall stability of the cable trough. Even in the case of external impact or vibration, it can effectively prevent relative displacement between the trough body 1 and the cover plate 2, ensuring that the cables are always in a safe accommodation space.

[0050] Furthermore, the second locking assembly includes: A second locking member 41, the second locking member 41 is disposed on one of the first side plate 12 and the second side plate 22; The second locking groove 42 is formed on the other of the first side plate 12 and the second side plate 22 . The second locking member 41 is adapted to be snapped into the second locking groove 42 to limit the movement of the cover plate 2 relative to the tank body 1 .

[0051] It is easy to understand that the cooperation between the second locking member 41 and the second locking groove 42 can provide a strong locking force, effectively limiting the movement of the cover plate 2 relative to the groove body 1. On the basis of the first elastic locking component, the overall stability of the cable groove is further enhanced to ensure that the cables are reliably protected in the groove.

[0052] In this embodiment, the second locking member 41 is preferably disposed on the first side plate 12, and the second locking groove 42 is disposed on the second side plate 22, which is more convenient for installation. Specifically, the second locking member 41 is a cylinder, and the second locking groove 42 is a through hole adapted to the cylinder.

[0053] In other embodiments, a buckle-type locking method can be selected as the second locking component, with a buckle provided on one of the first side plate 12 and the second side plate 22, and a buckle position provided on the other. When the cover plate 2 is covered on the slot, the buckle is buckled on the buckle position to achieve locking. The buckle-type locking method can provide a large locking force and can better fix the cover plate 2 and the slot body 1.

[0054] Furthermore, the length of the cover plate 2 perpendicular to the length direction of the cable is greater than the length of the slot body 1 perpendicular to the length direction of the cable. When the top plate 21 is covered on the slot, a gap is set between the first side plate 12 and the second side plate 22 on the same side.

[0055] It is easy to understand that the length of the cover plate 2 perpendicular to the length of the cable is greater than the length of the slot body 1 perpendicular to the length of the cable, so that there is more operating space when installing the cover plate 2. It is easier for the installer to place the cover plate 2 accurately on the slot, improving the installation efficiency. When the cover plate 2 needs to be removed for cable maintenance or replacement, the gap provides convenience for the removal operation. The cover plate 2 can be removed more easily.

[0056] Furthermore, it also includes a limiting plate 5, which is arranged on the first side plate 12 and / or the second side plate 22, and the thickness of the limiting plate 5 is less than or equal to the width of the gap.

[0057] It is easy to understand that the setting of the limiting piece 5 can limit the relative displacement between the first side plate 12 and the second side plate 22 to a certain extent, thereby enhancing the overall stability of the wire trough. When the cover plate 2 is installed on the trough body 1, the setting of the limiting piece 5 will cause a gap between the first side plate 12 and the second side plate 22, thereby preventing the problem that the trough body 1 and the cover plate 2 are tightly attached and difficult to disassemble after assembly, thereby improving the convenience of disassembly and assembly of the wire trough. When the wire trough is subjected to external force, the limiting piece 5 can prevent the first side plate 12 and the second side plate 22 from excessive deformation or dislocation, thereby ensuring the structural integrity of the wire trough.

[0058] In an optional embodiment, the thickness of the limiting piece 5 may be smaller than the width of the gap, so as to ensure that the limiting piece 5 can function without affecting the normal installation and removal of the cover plate 2. Of course, in a preferred embodiment, the thickness of the limiting piece 5 may also be set equal to the width of the gap, thereby further enhancing the structural stability of the wire trough.

[0059] Furthermore, the limiting piece 5 and the second locking assembly are arranged on the first side plate 12 on the same side.

[0060] It should be noted that the limiting piece 5 and the second locking assembly are arranged on the same side so that they can work together better. When the cover plate 2 is covered on the slot, the second locking assembly first takes effect to limit the movement of the cover plate 2 relative to the slot body 1. The limiting piece 5 further enhances the stability between the first side plate 12 and the second side plate 22 on the basis of the second locking assembly.

[0061] According to an embodiment of the present invention, on the other hand, a method for installing the above cable duct is also provided, comprising the following steps: Place the tank body 1 at the installation position; Lay the cables in the tank 1 according to the design requirements; Pick up the cover 2 and align it with the slot, and cover the cover 2 from the side provided with the first elastic locking component to the slot from top to bottom. In the process of the cover 2 covering the slot, the first elastic locking component will automatically compress and store energy. When the cover 2 is completely covered on the slot, the first elastic locking component will release energy to fix the cover 2 and the slot body 1 together, and the installation is completed.

[0062] It should be noted that when the cover 2 covers the slot, the cover 2 must first be tilted as a whole so that the side of the cover 2 close to the first elastic locking component is in a low position. When the cover 2 is covered on the slot body 1, the cover 2 is changed from tilted to horizontal. After the first elastic locking component completes the locking action, the cover 2 is fixedly connected to the slot body 1.

[0063] Furthermore, when the cover plate 2 is covered on the notch, the second locking member 41 is aligned with the second locking groove 42 , and the second locking member 41 is pushed to be engaged in the second locking groove 42 .

[0064] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
