Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct which is easy to assemble and disassemble. Background Art

[0002] Bus ducts are enclosed metal structures made of copper and aluminum busbars, used to distribute high power to various components in a distributed system. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects.

[0003] Related technology (publication number: CN213521190U) discloses a bus duct that is easy to disassemble and assemble. The disclosed technical solution is: the conductors in two adjacent duct bodies are plugged into the second groove on the mounting sleeve, and the fasteners are inserted into the first through hole and the second through hole to fix the mounting sleeve on the duct body. The mounting sleeve is connected to the adjacent duct bodies in a detachable manner, so that the duct body can be quickly removed during maintenance or replacement, which greatly improves the work efficiency of maintenance and replacement of the bus duct. By avoiding welding or gluing steps, the installation is more convenient. The fasteners are used to fix the mounting sleeve and the duct body, thereby improving the connection strength between the connector and the shell.

[0004] In the above-mentioned disclosed technical solutions, the following problems were found in the related technologies: when installing the bus duct, it is necessary to install it according to the laid lines. The existing bus duct installation method is to install the bus duct on the laid lines through fixings. Once the position needs to be adjusted, the bus duct needs to be removed and nailed again, which makes the adjustment process more cumbersome, thereby affecting the efficiency of the bus duct installation. For this reason, we have proposed a new type of bus duct that is easy to disassemble and assemble.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

In order to solve the problem of bus duct disassembly and assembly in the above-mentioned prior art, the present invention provides a bus duct that is easy to disassemble and assemble. The utility model adopts an adjustable locking structure combined with a detachable structure to facilitate the maintenance of the bus duct. The specific technical solution is as follows:

[0007] A bus duct that is easy to disassemble and assemble, comprises a bus duct, a slide is fixedly installed on the side wall of the bus duct, an adjustment base is slidably provided on the outside of the slide, the side wall of the adjustment base is provided with a fixed seat for connecting to a mounting surface, a groove cavity is opened on the side wall of the slide away from the bus duct, wedge-shaped ladders are laid in sequence inside the groove cavity, a non-return clamp corresponding to the wedge-shaped ladder is provided on the inner wall of the adjustment base, and a reverse switching component is provided on the adjustment base for driving the non-return clamp to disengage from the wedge-shaped ladder.

[0008] In the above technical solution, the reverse switching assembly includes a connecting rod fixedly mounted on the side wall of the anti-reverse clamp, and the end of the connecting rod away from the anti-reverse clamp is fixedly connected to a reverse opening member, and the connecting rod passes through the side wall of the adjustment base and extends to the outside, and an elastic member sleeved on the outside of the connecting rod is provided between the adjustment base and the reverse opening member.

[0009] Locking seats are symmetrically fixedly installed on both side walls of the adjustment base, and locking screws are threadedly connected to the locking seats.

[0010] Connecting frames are symmetrically fixedly installed on both side walls of the adjustment base. The connecting frames are sleeved on the outside of the locking screw. The side of the connecting frame away from the adjustment base is fixedly connected to the fixing base through a connecting column.

[0011] Slideways are symmetrically fixedly installed on both sides of the slide platform, and slide grooves corresponding to the slideways are symmetrically opened on both sides of the inner wall of the adjustment base.

[0012] The length of the slideway is the same as that of the slide platform, and no limiting members are provided at both ends of the slideway.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] A bus duct that is easy to assemble and disassemble comprises a bus duct 1, a slide 2 being fixedly mounted on the side wall of the bus duct 1, and an adjustment base 3 being slidingly mounted on the outside of the slide 2. The slides 2 are fixedly mounted longitudinally on the outer shell surface on both sides of the bus duct 1, and the adjustment base 3 is sleeved on the outside of the slide 2 so that the adjustment base 3 slides in contact with the outer wall of the slide 2. The side wall of the adjustment base 3 is provided with a fixing seat 5 for connecting to the mounting surface. The fixing seat 5 is fixed to the installation position of the bus duct by bolts, and then the slides 2 on both sides of the bus duct 1 are slid into the interior of the adjustment base 3, and then the line is laid. Thereafter, the slide 2 is slid between the two adjustment bases 3 according to the line laying situation, thereby adjusting the position of the bus duct 1, and fixing it after adjusting to the appropriate position, thereby ensuring the efficiency of the installation process of the bus duct 1.

[0030] A slot 16 is formed on the side wall of the slide 2 facing away from the bus duct 1. The slot 16 is formed on the surface of the slide 2 facing away from the bus duct 1. Multiple wedge-shaped ladders 7 are evenly and securely mounted on the inner wall of the slot 16 on the side close to the bus duct 1, from top to bottom. The wedge-shaped ladders 7 are right-angled triangles, with their longitudinal right-angled sides fitting against the inner wall of the slot 16. The wedge-shaped ladders 7 are sequentially laid out inside the slot 16. The inner wall of the adjustment base 3 is provided with a non-return clamp 8 corresponding to the wedge-shaped ladder 7, and the adjustment base 3 is provided with a reverse switching assembly that drives the non-return clamp 8 to disengage from the wedge-shaped ladder 7.

[0031] The inner wall of the adjustment base 3 facing the slide 2 is connected to the anti-return clamp 8 through a reverse switching assembly. The anti-return clamp 8 has the same shape as the wedge-shaped ladder 7. The position of the anti-return clamp 8 during installation ensures that the inclined surface of the anti-return clamp 8 contacts the inclined surface of the anti-return clamp 8.

[0032] In the process of adjusting the position of the bus duct 1 between the two adjustment bases 3 through the slide 2, the wedge-shaped ladder 7 in the slot cavity 16 slides over the surface of the anti-return clamp 8 in turn. The anti-return clamp 8 and the right-angle edge of the wedge-shaped ladder 7 limit the bus duct 1 to prevent reverse movement after the position is adjusted, thereby avoiding the position deviation of the bus duct 1 and ensuring the accuracy of the installation of the bus duct 1.

[0033] The bus duct 1 is then adjusted to a suitable laying position through the sliding fit between the anti-return clamp 8 and the wedge-shaped clamping ladder 7, thereby ensuring the efficiency of the cable laying process.

[0034] When the bus duct 1 needs to be removed for maintenance, the anti-return clamp 8 and the wedge-shaped ladder 7 are disengaged through the reverse switching component, and the slide 2 is directly slid out from the adjustment base 3 for maintenance, thereby bringing convenience to the maintenance process of relevant personnel.

[0035] The reverse switching assembly includes a connecting rod 11 fixedly mounted on the side wall of the anti-return clamp 8. The end of the connecting rod 11 away from the anti-return clamp 8 is fixedly connected to the reverse opening member 14. The connecting rod 11 passes through the side wall of the adjustment base 3 and extends to the outside. An elastic member 13 is provided between the adjustment base 3 and the reverse opening member 14 and is sleeved on the outside of the connecting rod 11. One end of the connecting rod 11 is vertically fixed to the surface of the anti-return clamp 8 facing the reverse opening member 14. The other end of the connecting rod 11 passes through the side wall of the adjustment base 3, extends to the outside and is vertically fixed to the surface of the reverse opening member 14. The connecting rod 11 slides in the through hole of the adjustment base 3.

[0036] The elastic member 13 can be a compression spring, and the two ends of the elastic member 13 are respectively fixed on the opposite surfaces of the adjustment base 3 and the reverse opening member 14. The elastic member 13 is movably sleeved on the outer wall of the connecting rod 11, so that the elastic member 13 fits the outer wall of the connecting rod 11 and slides telescopically.

[0037] During the process of adjusting the position of the bus duct 1, the wedge-shaped ladders 7 on the slide 2 slide over the anti-return clamps 8 one by one, causing the anti-return clamps 8 to drive the reverse opening member 14 to move via the connecting rod 11. At this time, the elastic member 13 is compressed and generates elastic force. After the reverse opening member 14 slides over the anti-return clamps 8 in the corresponding position, the elastic force of the elastic member 13 causes the reverse opening member 14 to be engaged between two adjacent wedge-shaped ladders 7, thereby locking the position of the bus duct 1.

[0038] When the bus duct 1 needs to be removed for maintenance, the reverse opening member 14 is pulled outward so that the reverse opening member 14 drives the anti-reverse clamp 8 to disengage from the wedge-shaped ladder 7 through the connecting rod 11, thereby removing the bus duct 1 from the two adjustment bases 3.

[0039] It is worth noting that the two side walls of the adjustment base 3 are symmetrically fixed with locking seats 17, and the locking screws 9 are threadedly connected to the locking seats 17. The two L-shaped locking seats 17 are respectively attached to the two side surfaces of the adjustment base 3, and the locking screws 9 are threadedly connected on the lateral surfaces of the locking seats 17.

[0040] After the bus duct 1 is adjusted to a suitable position, the locking screw 9 is screwed to engage the locking screw 9 with the outer shell surface of the bus duct 1, thereby locking the position of the bus duct 1 to prevent the position of the bus duct 1 from sliding and offsetting, thereby ensuring the stability of the installation of the bus duct 1.

[0041] In addition, connecting frames 4 are symmetrically fixedly installed on both side walls of the adjustment base 3. The connecting frames 4 are sleeved on the outside of the locking screw 9. The side of the connecting frame 4 away from the adjustment base 3 is fixedly connected to the fixed base 5 through a connecting column 10.

[0042] The locking screw 9 is given space by the through hole on the connecting frame 4 , ensuring that the position of the locking screw 9 does not interfere with the fixing seat 5 .

[0043] In addition, slideways 6 are symmetrically fixed on both sides of the slide 2, and slide grooves 12 corresponding to the slideways 6 are symmetrically opened on both sides of the inner wall of the adjustment base 3. The sliding cooperation between the slideways 6 and the slide grooves 12 ensures the smoothness of the adjustment process of the bus duct 1.

[0044] Furthermore, the length of the slideway 6 is the same as that of the slide 2, and no stoppers are provided at either end of the slideway 6. The slideway 6 is the same length as the slide 2, allowing the bus duct 1 to be slid out from between the two adjustment bases 3 and removed, thus facilitating maintenance operations for personnel.

[0045] The anti-return clamp 8 has the same structure as the wedge-shaped ladder 7. The anti-return clamp 8 has the same shape and size as the wedge-shaped ladder 7. The cross-section of the anti-return clamp 8 and the wedge-shaped ladder 7 is a right triangle, thereby ensuring the stability of the bus duct 1 during the position adjustment process.

[0046] The slide 2 is fixedly mounted on the detachable housing of the bus duct 1. When the bus duct 1 is inspected and maintained, the bus duct 1 can be directly removed from the protective housing, thereby facilitating the inspection and maintenance of the bus duct 1.

[0047] The present embodiment provides a bus duct that is easy to disassemble and assemble. The working principle is as follows: first, the fixing seat 5 is fixed to the installation position of the bus duct by bolts, and then the slides 2 on both sides of the bus duct 1 slide into the interior of the adjustment base 3.

[0048] During line laying, if the position of the bus duct 1 needs to be adjusted, the slide 2 is slid between the two adjustment bases 3. As the wedge-shaped ladders 7 on the slide 2 slide over the anti-return clamps 8, the anti-return clamps 8 drive the reverse opening member 14 via the connecting rod 11. At this time, the elastic member 13 is compressed and generates an elastic force. After the reverse opening member 14 slides over the anti-return clamps 8 in the corresponding position, the elastic force of the elastic member 13 causes the reverse opening member 14 to engage between the two adjacent wedge-shaped ladders 7, thereby locking the position of the bus duct 1.

[0049] When the bus duct 1 needs to be removed for inspection, the reverse opening member 14 is pulled outward, so that the reverse opening member 14 drives the anti-reverse clamp 8 to disengage from the wedge-shaped ladder 7 through the connecting rod 11, thereby removing the bus duct 1 from the two adjustment bases 3, and then the bus duct 1 is inspected and repaired.
