Description

An easily adjustable electrical construction hanger Technical Field

[0001] This utility model relates to the field of electrical construction hoisting technology, and in particular to an easily adjustable electrical construction hoisting. Background Technology

[0002] Electrical installation hangers are important supporting accessories used in electrical installation projects to suspend electrical equipment and components such as cable trays, conduits, and lighting fixtures. They are generally made of high-quality metal materials, such as hot-dip galvanized steel, which have good strength and rust resistance, ensuring long-term stable operation in various complex environments. They can also be flexibly installed on building structures such as ceilings and walls to reliably suspend electrical facilities of different weights and sizes.

[0003] Existing technologies, such as the utility model patent with publication number CN210669273U, disclose an easily adjustable electrical construction hanger. This patent uses a fixed plate and a cover plate. The lower surface of the fixed plate is fixedly connected to a wheel and a first support rod. The first support rod has a first groove. This solves the problem that the hangers currently used by workers in electrical construction are difficult to rotate and adjust according to the direction of the wires once fixed, and the fixed height cannot be adjusted according to the construction needs. If adjustment is required, it must be re-fixed and installed, which will affect the smooth progress of electrical construction.

[0004] In the process of fixing electrical equipment such as cable trays with hangers, existing adjustable hangers, such as those mentioned above, use hooks and cables to adjust the hangers. However, due to the unevenness of the wall top, in order to ensure the horizontal installation of water and electricity pipes, users need to fine-tune the length of the hangers at different heights during installation. When using hooks and cables for adjustment, the adjustment range of the hangers is limited to a certain range, making it difficult to ensure the horizontal level of electrical equipment such as cable trays at different positions after the hangers are adjusted. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem in the prior art that users need to fine-tune the length of the hanger at different heights when installing the hanger. When using hooks and cables for adjustment, the adjustment range of the hanger is limited to a certain range, making it difficult to ensure the level of electrical equipment such as cable trays at different positions after the hanger is adjusted. Therefore, this utility model proposes a hanger for electrical construction that is easy to adjust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a conveniently adjustable electrical construction hoist, comprising an upper hoist, a connecting assembly at the lower end of the upper hoist, a lower hoist at the end of the connecting assembly away from the upper hoist, the connecting assembly comprising an upper telescopic rod, the upper telescopic rod being slidably connected to the inner wall of the upper hoist, a connecting frame being fixedly connected to the lower surface of the upper telescopic rod, a lower telescopic rod being fixedly connected to the lower surface of the connecting frame, the lower telescopic rod being slidably connected to the inner wall of the lower hoist, a pull rod being slidably connected to the inner wall of the connecting frame, a linkage frame being fixedly connected to the rear end of the pull rod, a connecting arm being rotatably connected to both the left and right ends of the linkage frame, a sleeve being fixedly connected to the front surface of the connecting frame, the sleeve being sleeved with the surface of the pull rod, and a fastening sleeve being threadedly connected to the outer circumference of the sleeve;

[0007] The connecting assembly also includes a guide rod, which is fixedly connected to the side surface of the connecting frame. A connecting frame is slidably connected to the surface of the guide rod. A second connecting arm is rotatably connected to the inner wall of the connecting frame. Positioning frames are fixedly connected to the opposing ends of the upper and lower suspension rods. The second connecting arm is rotatably connected to the inner wall of the positioning frame.

[0008] Preferably, the inner arc surface of the sleeve is provided with a groove, and a rubber gasket is fixedly connected to the inner wall of the groove. The rubber gasket is in contact with the surface of the pull rod. The rubber gasket can increase the friction coefficient of the contact part between the sleeve and the pull rod when the sleeve is locked, thereby enhancing the stability of the pull rod when it is clamped by the sleeve.

[0009] Preferably, the upper telescopic rod has a protrusion on its arc surface. The protrusion of the upper telescopic rod is slidably connected to the inner wall of the upper rod. The protrusion on the surface of the upper telescopic rod can guide the movement direction of the upper telescopic rod to ensure that the upper telescopic rod always moves in the same direction when it is extended or retracted.

[0010] Preferably, the lower telescopic rod has a protrusion on its arc surface. The protrusion of the lower telescopic rod is slidably connected to the inner wall of the lower suspension rod. The protrusion on the surface of the lower telescopic rod can guide the movement direction of the lower telescopic rod to ensure that the lower telescopic rod always moves in the same direction when it is extended or retracted.

[0011] Preferably, the end of the clamp away from the connecting frame is provided with a chamfer. By providing a chamfer at the outer end of the clamp, the user can easily put the fastening sleeve on the clamp and tighten it, thereby improving the efficiency of the user in putting on the fastening sleeve.

[0012] Preferably, there are two guide rods, which are arranged symmetrically about the vertical center line of the connecting frame. The guide rods can guide the movement direction of the connecting frame, thereby ensuring that the connecting frame moves in the specified direction when it moves.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting an adjustment component, the adjustment range of the hanger can be effectively increased while ensuring convenient adjustment. This reduces the problem of limited adjustment range of the hanger when adjusting it by hook, which can easily lead to a decrease in the levelness after adjustment. Furthermore, it improves the practicality of the hanger and provides users with a more reliable and efficient solution for installation on uneven wall tops. Attached Figure Description

[0023] Please refer to Figures 1-6. This utility model provides a technical solution: a conveniently adjustable electrical construction hanger, including an upper hanger 1, a connecting component 2 at the lower end of the upper hanger 1, and a lower hanger 3 installed at the end of the connecting component 2 away from the upper hanger 1.

[0024] In this embodiment: the connecting component 2 includes an upper telescopic rod 21, which is slidably connected to the inner wall of the upper hanging rod 1. A connecting frame 22 is fixedly connected to the lower surface of the upper telescopic rod 21, and a lower telescopic rod 23 is fixedly connected to the lower surface of the connecting frame 22. The lower telescopic rod 23 is slidably connected to the inner wall of the lower hanging rod 3. A pull rod 24 is slidably connected to the inner wall of the connecting frame 22. A linkage frame 25 is fixedly connected to the rear end of the pull rod 24. A connecting arm 26 is rotatably connected to both the left and right ends of the linkage frame 25. A sleeve 27 is fixedly connected to the front surface of the connecting frame 22. The sleeve 27 is sleeved with the surface of the pull rod 24. A fastening cylinder 29 is threadedly connected to the outer circumference of the sleeve 27.

[0025] The connecting assembly 2 also includes a guide rod 210, which is fixedly connected to the side surface of the connecting frame 22. A connecting frame 211 is slidably connected to the surface of the guide rod 210. A connecting arm 212 is rotatably connected to the inner wall of the connecting frame 211. A positioning frame 213 is fixedly connected to the opposite ends of the upper hanging rod 1 and the lower hanging rod 3. The connecting arm 212 is rotatably connected to the inner wall of the positioning frame 213.

[0026] Specifically, the inner arc surface of the sleeve 27 has a groove, and a rubber gasket 28 is fixedly connected to the inner wall of the groove. The rubber gasket 28 is in contact with the surface of the pull rod 24.

[0027] In this embodiment, the rubber gasket 28 can increase the coefficient of friction at the contact point between the sleeve 27 and the pull rod 24 when the sleeve 27 is locked, thereby enhancing the stability of the pull rod 24 when it is clamped by the sleeve 27.

[0028] Specifically, the upper telescopic rod 21 has a protrusion on its arc surface. The protrusion of the upper telescopic rod 21 is slidably connected to the inner wall of the upper hanging rod 1. The protrusion on the surface of the upper telescopic rod 21 can guide the movement direction of the upper telescopic rod 21 to ensure that the upper telescopic rod 21 always moves in the same direction when it is extended or retracted.

[0029] Specifically, the lower telescopic rod 23 has a protrusion on its arc surface, and the protrusion of the lower telescopic rod 23 is slidably connected to the inner wall of the lower suspension rod 3.

[0030] In this embodiment, the protrusions on the surface of the lower telescopic rod 23 can guide the movement direction of the lower telescopic rod 23 to ensure that the lower telescopic rod 23 always moves in the same direction when it is extended or retracted.

[0031] Specifically, the end of the sleeve 27 away from the connecting frame 22 is provided with a chamfer. By providing a chamfer at the outer end of the sleeve 27, it is convenient for the user to put the fastening sleeve on the sleeve 27 and tighten it, thereby improving the efficiency of the user in putting on the fastening sleeve.

[0032] Specifically, there are two guide rods 210, which are arranged symmetrically about the vertical center line of the connecting frame 22.

[0033] In this embodiment, the guide rod 210 can guide the movement direction of the connecting frame 211, thereby ensuring that the connecting frame 211 moves in the specified direction when it moves.

[0034] Working principle: When installing the hanger, the upper hanger 1 is installed into the installation hole prepared by the construction personnel through the bolt structure at the top of the upper hanger 1. After the upper hanger 1 is fixed, the lower hanger 3 is inserted into the installation hole reserved in the cable tray and locked with nuts. After completion, the installation of the entire hanger is complete.

[0035] When the boom needs adjustment, use a laser level to mark the lower end of the boom at the designed height. After marking, adjust the boom according to the mark. During adjustment, rotate the fastening cylinder 29 counterclockwise. The fastening cylinder 29 disengages from the clamp 27, and the clamp 27 loses its locking, stopping the clamping and locking of the pull rod 24. Then, according to the position of the lower boom 3, pull or push the pull rod 24. The pull rod 24 drives the linkage frame 25, which in turn drives the connecting arm 26. The connecting arm 26 unfolds or closes under force and operates... During the movement, the connecting frame 211 is driven to move. Under the guidance of the guide rod 210, the connecting frame 211 moves and moves in coordination with the opening or closing movement of the connecting arm 212 to move the positioning frame 213. During the movement, the positioning frame 213 pushes or pulls the upper suspension rod 1 and the lower suspension rod 3 in the specified direction. Under the guidance of the upper telescopic rod 21 and the lower telescopic rod 23, the upper suspension rod 1 and the lower suspension rod 3 move in opposite directions in the specified direction. During the movement, the upper suspension rod 1 and the lower suspension rod 3 will adjust the overall length of the suspension rod.

[0036] When the end of the lower rod 3 is adjusted to the marked position on the laser level, the fastening cylinder 29 is pushed towards the sleeve 27. When the fastening cylinder 29 is fitted onto the surface of the sleeve 27, the fastening cylinder 29 is rotated clockwise. After the fastening cylinder 29 is tightened, the sleeve 27 can work with the rubber gasket 28 to lock the position of the pull rod 24 again, thus completing the adjustment operation of the rod. By setting the adjustment component, while ensuring the convenience of adjustment, the adjustment range of the rod can be effectively improved. This reduces the problem of limited adjustment range of the rod when adjusting the rod by hook, which can easily lead to a decrease in the levelness after adjustment. It further improves the practicality of the rod and provides users with a more reliable and efficient solution for installation on uneven wall tops.
