Description

Technical Field

[0001] This utility model relates to the field of busbar trunking technology, and specifically to an improved dense busbar trunking. Background Technology

[0002] Compact busbar trunking is a power distribution device suitable for AC three-phase four-wire and three-phase five-wire systems for transmitting current. Compact busbar trunking generally consists of a busbar trunking shell, conductive copper busbars located inside the busbar trunking shell, and a cover plate used to seal the busbar trunking shell. During the hoisting process of the busbar trunking, a hoisting rod and a hoisting plate on the hoisting rod are used to hoist and connect to the pre-installation plane.

[0003] During the installation process, existing busbar trunking is usually installed and fixed using the mounting holes reserved on the overall frame of the busbar trunking. However, the mounting holes reserved on the overall frame of the busbar trunking are not suitable for all installation locations, which greatly reduces its applicability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an improved compact busbar trunking. This solves the problem that existing busbar trunking is usually installed and fixed using the mounting holes reserved on the overall frame of the busbar trunking. However, the mounting holes reserved on the overall frame of the busbar trunking are not suitable for all installation locations, which greatly reduces the applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved high-density busbar trunking includes a busbar trunking housing and a hoisting mechanism disposed at both ends thereof. The hoisting mechanism includes a support plate located at the bottom of the busbar trunking housing. Connecting plates are symmetrically arranged on both sides of the top of the support plate. A drive threaded groove is formed through the connecting plate. A drive threaded rod is screwed into the drive threaded groove. A limiting post is provided at one end of the drive threaded rod. A fastening groove is formed through the drive threaded rod. A locking groove communicating with the fastening groove is formed at the other end of the drive threaded rod. A locking rod with one end extending into the fastening groove is slidably disposed in the locking groove.

[0007] As a preferred technical solution of this utility model, a guide groove is provided on the top end face of the support plate, and a guide plate adapted to the guide groove is provided on the bottom end face of the busbar housing.

[0008] The above technical solution utilizes the guide groove and guide plate to facilitate the displacement of the support plate at the bottom of the busbar trunking housing.

[0009] As a preferred technical solution of this utility model, the busbar trunking shell is provided with fixing plates on both sides, and the fixing plates are provided with multiple evenly distributed limiting grooves for the limiting posts to engage.

[0010] By using the above technical solution and the setting of the limiting groove, the position adjustment of the hoisting mechanism can be limited and fixed.

[0011] As a preferred embodiment of this utility model, the drive threaded rod is provided with a receiving groove that communicates with the locking groove, and a stop plate that is connected to the locking rod is slidably provided in the receiving groove.

[0012] As a preferred technical solution of this utility model, a drive spring is coaxially sleeved on the outside of the locking rod in the accommodating groove. One end of the drive spring is connected to the stop plate, and the other end of the drive spring is connected to the inner side wall of the accommodating groove.

[0013] The above technical solution utilizes the elastic force generated by the drive spring, thereby improving the stability of the locking rod inserted into the through hole.

[0014] As a preferred technical solution of this utility model, a mounting post is provided on the outer wall of the connecting plate on one side of the drive thread groove. A mounting groove is provided through the mounting post. A fastening post that can be inserted into the fastening groove is slidably provided in the mounting groove. A through hole for the locking rod to pass through is provided on the fastening post.

[0015] By using the above technical solution and the fastening post, the rotational displacement of the drive threaded rod can be limited, thus ensuring the stability of the limit post inserted into the limit groove.

[0016] As a preferred technical solution of this utility model, a traveling block is provided on the inner side wall of the mounting groove, and a traveling groove for the traveling block to move is provided on the outer side wall of the fastening column.

[0017] By using the above technical solution and the setting of the travel block and travel groove, it is possible to prevent the fastening column from detaching from the connection with the mounting column.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] When the installation position of the hoisting mechanism needs to be changed, firstly, the locking rod is pulled to displace it, causing it to disengage from the through hole on the fastening post. Then, the fastening post is displaced from its connection to the fastening groove in the drive threaded rod. Next, the drive threaded rod is driven to move the limiting post, causing it to disengage from the limiting groove in the fixed plate. At this point, the hoisting mechanism is moved to change its hoisting position. When the hoisting mechanism reaches the appropriate position, the drive threaded rod is turned to move the limiting post, causing it to engage with one of the limiting grooves on the fixed plate, thus limiting and fixing the movement of the hoisting mechanism. The fastening post is then inserted into the fastening groove in the drive threaded rod. Loosening the locking rod, under the action of the drive spring's own elasticity, causes the locking rod to engage with the through hole on the fastening post, thus restricting the rotational displacement of the drive threaded rod and ensuring the stability of the limiting post inserted into the limiting groove. This invention facilitates the adjustment of the hoisting mechanism's installation position by workers to adapt to the installation site environment, greatly improving its applicability and flexibility.

[0029] Example

[0030] This utility model provides an improved compact busbar trunking system, referenced... Figure 1-6 As shown, the invention includes a busbar housing 1 and a hoisting mechanism 2 disposed at both ends thereon. This invention facilitates the adjustment of the installation position of the hoisting mechanism 2 by the staff to adapt to the environment of the installation site, and greatly improves its applicability and flexibility.

[0031] The busbar housing 1 has symmetrically arranged fixing plates 102 on both sides. The fixing plates 102 have multiple evenly distributed limiting grooves 103 for engaging with the limiting posts 207. By setting the limiting grooves 103 and the limiting posts 207 on the fixing plates 102, the position adjustment of the hoisting mechanism 2 can be limited and fixed.

[0032] refer to Figure 3-6 As shown, the hoisting mechanism 2 includes a support plate 201 located at the bottom of the busbar housing 1. Connecting plates 202 are symmetrically arranged on both sides of the top of the support plate 201. A drive threaded groove is provided through the connecting plate 202. An installation post 206 is provided on the outer wall of the connecting plate 202 on one side of the drive threaded groove. A drive threaded rod 204 is screwed into the drive threaded groove. A limiting post 207 is provided at one end of the drive threaded rod 204. A fastening groove 211 is provided through the drive threaded rod 204. A locking groove 208 communicating with the fastening groove 211 is provided at the other end of the drive threaded rod 204. A locking rod 205 with one end extending into the fastening groove 211 is slidably arranged in the locking groove 208.

[0033] The support plate 201 has a guide groove 203 on its top end face, and the busbar housing 1 has a guide plate 101 on its bottom end face that matches the guide groove 203. The guide groove 203 and the guide plate 101 facilitate the displacement of the support plate 201 at the bottom of the busbar housing 1.

[0034] The drive threaded rod 204 has a receiving groove that communicates with the locking groove 208. A stop plate 209 connected to the locking rod 205 is slidably provided in the receiving groove. The stop plate 209 can compress the drive spring 210 to deform.

[0035] Furthermore, a drive spring 210 is coaxially sleeved on the outer side of the locking rod 205 within the receiving groove. One end of the drive spring 210 is connected to the stop plate 209, and the other end is connected to the inner sidewall of the receiving groove. The elastic force generated by the drive spring 210 improves the stability of the locking rod 205 inserted into the through hole 212 on the fastening post 216.

[0036] Referring to Figures 5-6, a mounting groove 214 is formed through the mounting post 206. A fastening post 216, which can be inserted into the fastening groove 211, is slidably disposed within the mounting groove 214. A through hole 212 is formed through the fastening post 216 for the locking rod 205 to pass through. The fastening post 216 restricts the rotational displacement of the drive threaded rod 204, ensuring the stability of the limiting post 207 inserted into the limiting groove 103.

[0037] The mounting groove 214 has a travel block 215 on its inner sidewall, and the fastening post 216 has a travel groove 213 on its outer sidewall for the travel block 215 to move. The travel block 215 and the travel groove 213 are provided to prevent the fastening post 216 from detaching from the mounting post 206.

[0038] The working principle of this utility model is as follows:

[0039] When the installation position of the hoisting mechanism 2 needs to be changed, firstly, pull the locking rod 205 to displace it, causing the locking rod 205 to disengage from the through hole 212 on the fastening post 216. Then, displace the fastening post 216 to disengage it from the fastening groove 211 inside the drive threaded rod 204. Next, drive the drive threaded rod 204 to move the limiting post 207, causing the limiting post 207 to disengage from the limiting groove 103 inside the fixing plate 102. At this time, drive the hoisting mechanism 2 to displace, thereby changing the hoisting position. When the hoisting mechanism 2 is moved to the appropriate position, turn the drive... The threaded rod 204 drives the limiting post 207 to move, causing the limiting post 207 to engage with one of the limiting grooves 103 on the fixing plate 102, thereby limiting and fixing the displacement of the hoisting mechanism 2. The fastening post 216 is then inserted into the fastening groove 211 within the driving threaded rod 204. The locking rod 205, loosened by the elastic force of the driving spring 210, is inserted into the through hole 212 on the fastening post 216, thus restricting the rotational displacement of the driving threaded rod 204 and ensuring the stability of the limiting post 207 within the limiting groove 103. This invention facilitates adjustments to the installation position of the hoisting mechanism 2 by workers to adapt to the installation site environment, greatly improving its applicability and flexibility.
