Technical Field

[0001] The utility model relates to the technical field of electric meters, in particular to an electric meter with a protection function. Background Art

[0002] Electric meter is the abbreviation of electric energy meter, which is an instrument used to measure electrical energy. It is also called watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities.

[0003] When the electric meter is put into use, it is usually installed inside the meter box, and then the user's wires are passed through the meter box and installed on the meter. After the installation is completed, the wires need to be neatly routed so that the wires are neatly laid inside the meter box to facilitate subsequent circuit maintenance.

[0004] However, it is inevitable that the wires will be pulled during the wiring process, and the wires and the electric meter are usually tightened by bolts. If the wires are pulled, the connection between the wires and the electric meter may become loose, and poor contact may occur, leading to leakage accidents, posing a safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide an electric meter with a protection function to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an electric meter with a protective function, comprising an electric meter body, a plurality of wiring holes are provided at the bottom of the electric meter body, and a protective mechanism for preventing the wires from falling off is provided at the bottom of the electric meter body. The protective mechanism can prevent the wires from being loosened from the wiring holes after being pulled, and the protective mechanism comprises:

[0007] L rods, the L rods are fixedly mounted at the bottom of the electric meter body, and the L rods are provided in two groups, and the two groups of L rods are mirror-imaged and arranged on both sides of the wiring hole with the wiring hole as the central axis;

[0008] A cross bar, one end of which is fixedly mounted on the side wall of the L-bar, and the other end of which is fixedly mounted with a concave rod, and the wires can be wound by setting the cross bar;

[0009] A baffle, one end of which is hinged on the outer wall of the concave rod, and the other end of which is attached to the side wall of the L rod and the electric meter body. The baffle can facilitate the entry of the wires into the closed space composed of the concave rod, the cross bar, the L rod and the baffle.

[0010] Preferably, a torsion spring is provided at the hinge between the baffle and the concave rod, and the baffle can be driven to rotate and reset by the torsion spring.

[0011] Preferably, a fixing mechanism for improving the stability of the wire is provided on the concave rod, and the fixing mechanism includes a threaded rod, which is threadedly connected to the inner wall of the concave rod and passes through the concave rod. By setting the threaded rod, the clamping plate can be driven to move inside the slide groove.

[0012] Preferably, a slide groove is provided on the cross bar, and a clamping plate is slidably connected to the inner wall of the slide groove, and the wires can be clamped by providing the clamping plate.

[0013] Preferably, a knob is fixedly mounted on one end of the threaded rod, and the other end of the threaded rod is rotatably connected to the side wall of the clamping plate.

[0014] Preferably, a plurality of groups of rubber pads are fixedly mounted on the outer wall of one side of the clamping plate away from the threaded rod.

[0015] Compared with the prior art, the utility model provides an electric meter with a protection function, which has the following beneficial effects:

[0016] 1. The electric meter with protection function can limit the wires wrapped on the cross bar by setting the concave rod, the cross bar, the L rod and the baffle. The two sets of cross bars can wrap the wires. When the wires are pulled, the two sets of cross bars can absorb most of the pulling force, avoiding the connection between the wires and the wiring holes from being pulled strongly, causing the connection between the wires and the wiring holes to become loose, and improving the stability of the connection between the wires and the wiring holes.

[0017] 2. The electric meter with protection function can turn the threaded rod by turning the knob, and at the same time cooperate with the clamping plate and the L rod to clamp the wires wrapped around the cross bar, so that the wires can be wrapped around the cross bar more stably, avoiding the wires from loosening on the cross bar, causing the tension on the wires to be directly transmitted to the connection with the wiring hole, thereby further improving the stability of the wires.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an electric meter with a protection function, comprising an electric meter body 1, a plurality of wiring holes 2 are provided at the bottom of the electric meter body 1, and a protection mechanism 3 is provided at the bottom of the electric meter body 1 to prevent the wires from falling off. By providing the protection mechanism 3, the wires can be prevented from loosening from the wiring holes 2 after being pulled.

[0024] The protective mechanism 3 comprises an L-rod 31, a cross bar 32, a baffle 33, a concave rod 34, and a torsion spring 35; the L-rod 31 is fixedly mounted at the bottom of the electric meter body 1, and two groups of L-rods 31 are provided, and the two groups of L-rods 31 are mirror-imaged on both sides of the wiring hole 2 with the wiring hole 2 as the central axis, one end of the cross bar 32 is fixedly mounted on the side wall of the L-rod 31, and the other end of the cross bar 32 is fixedly mounted with a concave rod 34, and the wires can be wound around the two groups of cross bars 32 by utilizing the gap between the baffle 33 and the L-rod 31. By winding the wires with the two groups of cross bars 32, when the wires are pulled, the two groups of cross bars 32 can absorb most of the pulling force to prevent the connection between the wire and the wiring hole 2 from being pulled strongly. One end of the baffle 33 is hinged to the outer wall of the concave rod 34, and the other end of the baffle 33 is attached to the side wall of the L rod 31 of the electric meter body 1. The closed space composed of the concave rod 34, the cross bar 32, the L rod 31, and the baffle 33 can limit the wires wound on the cross bar 32. A torsion spring 35 is provided at the hinge between the baffle 33 and the concave rod 34. The baffle 33 is rotated to rotate toward the cross bar 32 and compress the torsion spring 35, so that the baffle 33 is separated from the L rod 31 and a gap is left.

[0025] The above-mentioned concave rod 34 is provided with a fixing mechanism 4 for improving the stability of the wire. By setting the fixing mechanism 4, the wire can be tightly wound around the two sets of cross bars 32. The fixing mechanism 4 includes a threaded rod 41, a slide groove 42, a clamping plate 43, a knob 44, and a rubber pad 45; the threaded rod 41 is threadedly connected to the inner wall of the concave rod 34, and the threaded rod 41 penetrates the concave rod 34, and the cross bar 32 is provided with a slide groove 42, and the inner wall of the slide groove 42 is slidably connected with a clamping plate 43. The clamping plate 43 cooperates with the L rod 31 to clamp the wires wound on the cross bar 32, so that the wires can be more stably wound around the cross bar 3 2, to prevent the wires from loosening on the cross bar 32, causing the tension on the wires to be directly transmitted to the connection with the wiring hole 2, further improving the stability of the wires, one end of the threaded rod 41 is fixedly installed with a knob 44, the other end of the threaded rod 41 is rotatably connected to the side wall of the clamping plate 43, the threaded rod 41 is rotated by the knob 44, and the rotation of the threaded rod 41 can drive the clamping plate 43 to slide on the inner wall of the slide groove 42, and the outer wall of the clamping plate 43 away from the threaded rod 41 is fixedly installed with multiple groups of rubber pads 45, and the friction between the clamping plate 43 and the wires can be increased by setting the rubber pads 45.

[0026] The baffle 33 is then released to allow the wire to be wound around the two sets of cross bars 32 by utilizing the gap between the baffle 33 and the L bar 31 . The baffle 33 is then released to allow the baffle 33 to be rotated and reset by the elasticity of the torsion spring 35 , so that the baffle 33 is fitted with the L bar 31 . At this time, the closed space composed of the concave bar 34 , the cross bar 32 , the L bar 31 , and the baffle 33 can limit the position of the wire wound around the cross bar 32 . By winding the wires through the two sets of cross bars 32 , when the wires are pulled, the two sets of cross bars 32 can absorb most of the pulling force, thereby preventing the connection between the wires and the wiring hole 2 from being pulled hard, causing the connection between the wires and the wiring hole 2 to become loose, thereby improving the stability of the connection between the wires and the wiring hole 2 .

[0027] After the wires are wound around the two sets of cross bars 32, the threaded rod 41 is rotated by means of the knob 44. The rotation of the threaded rod 41 can drive the clamping plate 43 to move along the inner wall of the slide groove 42 toward the end close to the L rod 31, so that the rubber pad 45 on the side wall of the clamping plate 43 fits with the wires. The clamping plate 43 cooperates with the L rod 31 to clamp the wires wound around the cross bar 32, so that the wires can be wound around the cross bar 32 more stably, thereby preventing the wires from loosening on the cross bar 32, causing the tension on the wires to be directly transmitted to the connection with the wiring hole 2, thereby further improving the stability of the wires.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
