Abstract
Description
Technical Field
[0001] This utility model relates to the field of disconnecting switch technology, specifically a fully sealed disconnecting switch. Background Technology
[0002] A disconnecting switch is a disconnecting and connecting structure used to isolate power supplies. It connects the contacts to a metal part by pulling the switch to allow power to flow. If the switch head is pulled to separate the switch head from the metal part, the connection can be directly disconnected, which is safe and can immediately stop the power flow.
[0003] To ensure smooth power flow, the connectors and switch arms are made of specially made metal materials. Accidental contact can easily lead to electrical conductivity. Ordinary switch structures are mostly exposed to the air, lacking protection and easily accumulating dust and debris. Furthermore, the switch arms can easily jam when people pull on them.
[0004] Now, a novel fully sealed disconnect switch is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a fully sealed disconnect switch to solve the problem of lack of sealing protection mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully sealed disconnect switch, comprising a base plate and sliding grooves. The front end of the base plate is provided with three sets of sliding grooves, and a gate rod is movably connected in the sliding grooves. A balance bar is fixed between the top ends of the gate rods, and a handle is welded to the center of the top end of the balance bar. Two sets of hinges are installed on the right side of the front end of the base plate, and a cover is fixed between the left sides of the hinges. A layer of rubber sheet is attached to the inner wall of the cover. A pull block is fixed to the center of the left side of the cover. A locking block is fixed above and below the left side of the front end of the base plate. A locking groove is provided at the top and bottom of the front left side of the cover. An assembly piece is welded to the top and bottom of the base plate.
[0007] As a further technical solution of this utility model, the cover rotates horizontally to the right front of the base plate, and the cover covers the outside of the gate arm and the balance bar.
[0008] As a further technical solution of this utility model, the card block and the card slot are on the same horizontal plane, and the card block is embedded in the card slot.
[0009] As a further technical solution of this utility model, brackets are respectively installed on the upper and lower sides of the right side of the front end of the substrate, and a rotating shaft is movably connected between the upper and lower parts inside the bracket. A connecting rod is fixed at the center of the rotating shaft, and a limit block is fixed on the left side of the connecting rod. A pressure block is fixed on the right side of the connecting rod. Coil springs are respectively installed on the upper and lower sides between the bracket and the connecting rod.
[0010] As a further technical solution of this utility model, the coil springs are symmetrically sleeved on the upper and lower surfaces of the rotating shaft, and the coil springs and the rotating shaft are arranged in concentric circles.
[0011] As a further technical solution of this utility model, the pressure block, connecting rod and limiting block are on the same horizontal plane, and the connecting rod rotates laterally with the rotating shaft.
[0012] As a further technical solution of this utility model, a cross groove is provided at the rear of the substrate, and a slider is movably connected in the cross groove. A collar is provided inside the slider, and a wire harness is fixed in the collar. A bolt is threadedly connected inside the collar. A screw hole one is provided laterally at the lower edge of the cross groove, and a screw hole two is provided longitudinally at the right edge of the cross groove.
[0013] As a further technical solution of this utility model, the slider can rotate and slide in the cross groove, and the bolt can rotate back and forth in the slider.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the fully sealed disconnect switch not only achieves sealed protection of the gate body and prevents the gate body from sliding down, but also allows for adjustment of the wiring harness installation position;
[0015] By fixing a cover between the left sides of the hinge, holding the handle at the center of the balance bar, the gate rod is raised or lowered along the slide groove on the surface of the base plate to operate the disconnecting switch to supply current or disconnect the connection. Then, the cover installed on the hinge is closed so that the cover engages with the corresponding block with the slot on the left side. The rubber sheet on the inner wall of the cover can also prevent accidental human touch and prevent external dust particles from entering the switch.
[0016] By fixing a limit block on the left side of the connecting rod, the balance bar is vertically installed at the bottom of each gate arm. When the balance bar rises to the top or sinks to the bottom, the pressure block can be pressed down in advance to move it toward the groove on the surface of the base plate, and the limit block on the left side of the connecting rod will be raised. When the balance bar stops moving, the pressure block is released. Under the restriction of the upper and lower coil springs, the rotating shaft can be reset between the brackets, so that the limit block stays at the bottom or top of the balance bar, preventing the gate arm from loosening and causing the switch to close and the current to be cut off.
[0017] By providing a cross groove at the rear of the substrate, the slider can be moved at the cross groove at the rear of the substrate and can rotate in the cross groove. Simply align the slider with screw hole one or screw hole two, and then screw in the bolt for reinforcement. This can restrict the wire harness passing through the collar at the center, thereby achieving the purpose of adjusting the installation direction of the wire harness. It can also prevent the wire harness from being squeezed when installing the substrate through the assembly piece. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 An embodiment of this utility model provides a fully sealed disconnect switch, including a base plate 1 and a slide groove 8. The front end of the base plate 1 is provided with three sets of slide grooves 8, and a gate rod 10 is movably connected in the slide groove 8. A balance bar 7 is fixed between the top ends of the gate rod 10, and a handle 9 is welded to the center of the top end of the balance bar 7. Two sets of hinges 12 are installed on the right side of the front end of the base plate 1, and a cover 3 is fixed between the left sides of the hinges 12. A layer of rubber sheet 5 is attached to the inner wall of the cover 3. A pull block 6 is fixed to the center of the left side of the cover 3. A locking block 4 is fixed above and below the left side of the front end of the base plate 1, and a locking groove 25 is provided at the top and bottom of the front left side of the cover 3. An assembly piece 2 is welded to the top and bottom of the base plate 1.
[0025] The cover 3 rotates horizontally to the right front of the base plate 1. The cover 3 covers the outside of the gate arm 10 and the balance bar 7. The locking block 4 and the locking groove 25 are on the same horizontal plane, and the locking block 4 is embedded in the locking groove 25.
[0026] Specifically, such as Figure 1 and Figure 2As shown, by holding the handle 9 at the center of the balance bar 7, the gate bar 10 is raised or lowered along the slide groove 8 on the surface of the base plate 1 in order to operate the disconnecting switch to supply current or disconnect the connection. Then, the cover 3 installed on the hinge 12 is closed, so that the cover 3 is engaged with the corresponding block 4 by the slot 25 on the left side. The rubber sheet 5 on the inner wall of the cover 3 can also prevent accidental contact by human hand.
[0027] A bracket 11 is installed on the upper and lower sides of the front right side of the substrate 1, and a rotating shaft 15 is movably connected between the upper and lower parts inside the bracket 11. A connecting rod 16 is fixed at the center of the rotating shaft 15, and a limit block 17 is fixed on the left side of the connecting rod 16. A pressure block 13 is fixed on the right side of the connecting rod 16. A coil spring 14 is installed on the upper and lower sides between the bracket 11 and the connecting rod 16.
[0028] The coil spring 14 is symmetrically sleeved on the upper and lower surfaces of the rotating shaft 15. The coil spring 14 and the rotating shaft 15 are arranged in concentric circles. The pressure block 13, the connecting rod 16 and the limiting block 17 are on the same horizontal plane. The connecting rod 16 rotates laterally with the rotating shaft 15.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, the balance bar 7 is vertically installed at the bottom of each gate arm 10. When the balance bar 7 is raised to the top or lowered to the bottom, the pressure block 13 can be pressed down in advance to move it toward the groove on the surface of the base plate 1, and the limiting block 17 on the left side of the connecting rod 16 will be raised. When the balance bar 7 stops moving, the pressure block 13 is released. Under the restriction of the upper and lower coil springs 14, the rotating shaft 15 can be reset between the brackets 11, so that the limiting block 17 stays at the bottom or top of the balance bar 7.
[0030] A cross groove 18 is provided at the rear of the substrate 1, and a slider 20 is movably connected in the cross groove 18. A collar 21 is provided inside the slider 20, and a wire harness 19 is fixed in the collar 21. A bolt 23 is threaded inside the collar 21. A screw hole 22 is provided laterally at the lower edge of the cross groove 18, and a screw hole 24 is provided longitudinally at the right edge of the cross groove 18. The slider 20 can rotate and slide in the cross groove 18, and the bolt 23 can rotate back and forth in the slider 20.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the slider 20 is moved at the cross groove 18 behind the substrate 1, and the slider 20 can rotate in the cross groove 18. Simply align the slider 20 with the screw hole 22 or the screw hole 24, and then screw in the bolt 23 for reinforcement. This will restrict the wire harness 19 passing through the collar 21 at the center, thereby achieving the purpose of adjusting the installation direction of the wire harness 19 and facilitating installation at multiple angles.
[0032] Working principle: When using this utility model, firstly, move the slider 20 at the cross groove 18 behind the base plate 1. The slider 20 can rotate in the cross groove 18. Simply align the slider 20 with the screw hole 22 or screw hole 24, and then screw in the bolt 23 for reinforcement. This will restrict the wire harness 19 passing through the collar 21 at the center, making installation convenient. Hold the handle 9 at the center of the balance bar 7 and raise or lower the gate arm 10 along the sliding groove 8 on the surface of the base plate 1. Since the balance bar 7 is vertically installed at the bottom of each gate arm 10, when the balance bar 7 is raised to the top or lowered to the bottom... When the pressure block 13 is pressed down, it moves towards the groove on the surface of the base plate 1, and the limiting block 17 on the left side of the connecting rod 16 is raised. When the balance rod 7 stops moving, the pressure block 13 is released. Under the restriction of the upper and lower coil springs 14, the rotating shaft 15 can be reset between the brackets 11, so that the limiting block 17 stays at the bottom or top of the balance rod 7 to prevent the gate rod 10 from loosening. Then the cover 3 installed on the hinge 12 is closed, so that the cover 3 is engaged with the corresponding locking block 4 by the locking groove 25 on the left side. The rubber sheet 5 on the inner wall of the cover 3 can also prevent accidental contact by human hand.
