Description

Technical Field

[0001] This utility model relates to the field of power installation technology and equipment, and in particular to a novel meter box. Background Technology

[0002] A meter box is a box structure that protects multiple independent electricity meters. It can install multiple electricity meters in a meter box for protection and unified management.

[0003] During the installation of an electricity meter box, multiple electricity meters are typically installed inside. Wiring is required for these meters. However, especially outdoors, the long length of the wires can lead to loose connections, causing them to sag under their own weight for extended periods. This results in the wires being dragged along and swayed by wind, potentially causing them to detach and disrupt the normal operation of the meters. Utility Model Content

[0004] This utility model provides a novel meter box, which aims to solve the problem in the prior art where the connection between the meter and the wire terminal becomes unstable due to prolonged dragging of the wire, thus affecting the normal operation of the meter.

[0007] Two mounting rollers are arranged parallel to each other above the connecting groove, and the two mounting rollers are arranged along the length direction of the electrical box body; each of the two mounting rollers is provided with a clamping roller, and the outer contour of the clamping roller is provided with a variable diameter section with a gradually increasing diameter; the variable diameter sections on the two clamping rollers are arranged symmetrically.

[0008] Both of the mounting rollers are equipped with meshing synchronous gears;

[0009] Rotating one of the mounting rollers causes the other mounting roller to rotate in the opposite direction via the synchronous gear, adjusting the gap between the clamping rollers on the two mounting rollers to clamp the wire passing between the two clamping rollers.

[0010] In this embodiment, the distance between the clamping rollers is first adjusted to a larger position. Then, several wires are passed through the connecting groove into the electrical box body, then through the two clamping rollers, and finally connected to the meter inside the electrical box body. Afterward, the mounting roller is rotated to reduce the distance between the two clamping rollers, allowing them to clamp several wires simultaneously. This prevents the wires from being dragged by their own weight, ensuring the stability of the connection between the wires and the meter. Even if the wires sway due to wind, the stability of the connection between the meter and the wires will not be affected over a long period.

[0011] In one embodiment, locking components are provided at the ends of the two mounting rollers; the locking components include:

[0012] A locking frame is fixedly installed on the outside of the electrical box body, and the locking frame is located between the two mounting rollers; the locking frame has a transverse hole through it, and the two ends of the transverse hole correspond to the two mounting rollers respectively; a longitudinal hole is provided through the side wall of the transverse hole.

[0013] Two abutment rods are provided in the transverse hole, and a locking rod is provided in the longitudinal hole;

[0014] Several locking grooves are provided on the outer side walls of the two mounting rollers at positions corresponding to the transverse holes; the locking rod is inserted between the two abutment rods through the longitudinal hole, pushing the two abutment rods into the locking grooves of the corresponding mounting rollers respectively, thereby locking the mounting rollers.

[0020] In one embodiment, the locking frame is provided with fixing lugs on both sides for fixed connection with the electrical box body.

[0021] In one embodiment, a fixing through hole is provided on the fixing side ear, and a side wall through hole is provided on the side wall of the electrical box body. The bolt passes through the fixing through hole and the side wall through hole and is connected to the nut.

[0022] In one embodiment, both ends of the two abutment rods are rounded, and the locking rod is provided with a conical head near the transverse hole.

[0023] The advantages of this utility model compared with the prior art are:

[0024] (1) Protect the electrical connection: effectively clamp the wires to avoid dragging and loosening of the meter connection caused by the weight of the wires or wind swings, and ensure the long-term stability of the connection between the meter and the wires.

[0025] (2) Easy to operate: The installation roller can be easily adjusted by rotating it with a hex wrench. The design of the locking component makes it very convenient to fix and release the clamping state, which is convenient for the installation and replacement of wires.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms.

[0044] It should also be further understood that the term "and / or" as used in this utility model specification refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0045] Please see Figure 1-7 This utility model provides a novel meter box, including: a box body 1, wherein a plurality of communicating grooves 11 are provided through the box body 1 along its length direction;

[0046] Two mounting rollers 2 are arranged parallel above the connecting groove 11, and the two mounting rollers 2 are arranged along the length direction of the electrical box body 1; each of the two mounting rollers 2 is provided with a clamping roller 21, and the outer contour of the clamping roller 21 is provided with a variable diameter section 211 with a gradually increasing diameter; the variable diameter sections 211 on the two clamping rollers 21 are arranged symmetrically.

[0047] Both mounting rollers 2 are equipped with meshing synchronous gears 22;

[0048] Rotating one of the mounting rollers 2 causes the other mounting roller 2 to rotate in the opposite direction via the synchronous gear 22, adjusting the spacing between the clamping rollers 21 on the two mounting rollers 2, and clamping the wire passing between the two clamping rollers 21.

[0049] In this embodiment, two parallel mounting rollers 2 are set up. The two mounting rollers 2 can rotate synchronously through a synchronous gear 22. The clamping rollers 21 on the mounting rollers 2 are symmetrically arranged. This makes the distance between the two clamping rollers 21 gradually decrease when one of the mounting rollers 2 is rotated in one direction, and the distance between the two clamping rollers 21 gradually increase when the mounting roller 2 is rotated in the opposite direction.

[0050] Therefore, during use, the distance between the clamping rollers 21 can be adjusted to a larger position first. Then, several wires are passed through the connecting groove 11 into the electrical box body 1, then through the two clamping rollers 21, and finally connected to the meter inside the electrical box body 1. After that, the mounting roller 2 is rotated to reduce the distance between the two clamping rollers 21, so that the two clamping rollers 21 can clamp several wires simultaneously. This avoids the wires being dragged by their own weight, and will not affect the stability of the connection between the wires and the meter. Even if the wires sway due to wind, the stability of the connection between the meter and the wires will not be affected over a long period of time.

[0051] In a further embodiment, such as Figure 2 As shown, one of the mounting rollers 2 has a hexagonal screw head 23 at one end.

[0052] The end of the mounting roller 2 is provided with a hexagonal screw head 23, so that the mounting roller 2 can be rotated using a hexagonal wrench, thereby realizing the function of adjusting the distance between the clamping rollers 21.

[0053] In a further embodiment, both ends of the two mounting rollers 2 are provided with synchronous gears 22, and the synchronous gears 22 at both ends of the two mounting rollers 2 mesh with each other.

[0054] In other words, both ends of the mounting roller 2 in this embodiment are provided with synchronous gears 22, which makes there two meshing positions between the two mounting rollers 2, making the two mounting rollers 2 more stable during transmission, and also making the wires clamped better with the cooperation of the two clamping rollers 21.

[0055] In this embodiment, the synchronous gears 22 are all located inside the electrical box body 1. At the same time, bearings are provided on the side walls at both ends of the electrical box body 1 along its length, and the mounting rollers 2 are all inserted into the bearings.

[0056] The two ends of the mounting roller 2 are mounted on bearings, which allows the mounting roller 2 to rotate more flexibly.

[0057] In a further embodiment, the outer wall of the clamping roller 21 is fitted with a sponge sleeve.

[0058] The sponge sleeve is placed around the clamping roller 21. The sponge sleeve can prevent the wire from being pinched by the clamping roller 21 and plays a role in buffering and protecting the clamped wire.

[0059] In one embodiment, a locking assembly 3 for locking the two mounting rollers 2 is provided on the outer side wall of the electrical box body 1.

[0060] In this embodiment, the locking component 3 is disposed between the two mounting rollers 2, and the locking component 3 is disposed at the end of the mounting roller 2. The locking component 3 includes:

[0061] A locking frame 31 is fixedly installed on the outside of the electrical box body 1. The locking frame 31 is located between the two mounting rollers 2. The locking frame 31 has a transverse hole 311 through it, and the two ends of the transverse hole 311 correspond to the two mounting rollers 2 respectively. A longitudinal hole 312 is provided through the side wall of the transverse hole 311.

[0062] Two abutment rods 32 are slidably disposed in the transverse hole 311, and a locking rod 33 is disposed in the longitudinal hole 312;

[0063] On the outer side walls of the two mounting rollers 2, at positions corresponding to the transverse holes 311, a plurality of locking grooves 24 are provided; the locking rod 33 is inserted from the longitudinal hole 312 between the two abutment rods 32, pushing the two abutment rods 32 into the corresponding locking grooves 24 of the mounting rollers 2, thereby locking the mounting rollers 2. In this embodiment, the plurality of locking grooves 24 are evenly distributed along the outer side walls of the mounting rollers 2.

[0064] In this embodiment, when the locking rod 33 is not inserted into the transverse hole 311, the abutment rod 32 can slide freely in the transverse hole 311, and the mounting roller 2 can rotate freely, thereby allowing the mounting roller 2 to rotate arbitrarily and adjust the size of the gap between the two clamping rollers 21.

[0065] When the locking rod 33 is inserted into the transverse hole 311 through the longitudinal hole 312, the locking rod 33 will be inserted between the two abutting rods 32. The locking rod 33 will push the two abutting rods 32 away from each other, so that the ends of the two abutting rods 32 away from the locking rod 33 abut against the locking groove 24. At this time, the two abutting rods 32 and the locking rod 33 form a self-locking structure in the transverse hole 311. At this time, the abutting rods 32 play a locking role for the mounting roller 2.

[0066] Therefore, when it is necessary to clamp the wire, first rotate the mounting roller 2 to adjust the distance between the clamping rollers 21. Then, insert the locking rod 33 into the transverse hole 311 through the longitudinal hole 312, so that the locking rod 33 pushes the abutment rod 32 to abut against the mounting roller 2 in the transverse hole 311, thereby locking the mounting roller 2. When it is necessary to replace the wire, the locking rod 33 can be pulled out from the longitudinal hole 312 to release the lock on the abutment rod 32, allowing the mounting roller 2 to rotate freely. This increases the distance between the clamping rollers 21, allowing the wire to be pulled out from between the two clamping rollers 21 for replacement.

[0067] In a further embodiment, a protrusion 332 is provided at the end of the locking rod 33 away from the transverse hole 311.

[0068] The protrusion 332 allows the locking lever 33 to be easily inserted into or pulled out of the longitudinal hole 312.

[0069] In a further embodiment, both ends of the two abutment rods 32 are rounded heads 321, and the locking rod 33 is provided with a conical head 331 near the transverse hole 311.

[0070] In this embodiment, the two ends of the abutment rod 32 are set as arc heads 321, while the locking rod 33 is set as a conical head 331, so that the locking rod 33 can be smoothly inserted between the two abutment rods 32.

[0071] In a further embodiment, the locking frame 31 has fixing lugs 313 on both sides for fixed connection with the electrical box body 1. The fixing lugs 313 have fixing through holes, and the side wall of the electrical box body 1 has side wall through holes. Bolts pass through the fixing through holes and the side wall through holes and are then connected to nuts.

[0072] In this embodiment, the locking frame 31 is fixedly connected to the outer side wall of the electrical box body 1 via the fixed side ear 313, which facilitates the installation of the locking frame 31 on the outside of the electrical box body 1.

[0073] The working principle of this embodiment is as follows:

[0074] (1) Synchronous reverse motion: By rotating one of the mounting rollers 2, the other mounting roller 2 is driven to rotate synchronously in the opposite direction by using the synchronous gears 22 that mesh at both ends.

[0075] (2) Spacing adjustment: The clamping rollers 21 on the two mounting rollers 2 have symmetrically arranged variable diameter sections 211. When the mounting rollers 2 rotate in the opposite direction, the relative position of the variable diameter sections 211 changes, thereby realizing the adjustment of the spacing between the two clamping rollers 21.

[0076] (3) Clamping and releasing: Rotating the mounting roller 2 in the forward direction reduces the gap between the clamping rollers 21, which can clamp the wires passing through it; rotating in the reverse direction increases the gap, thereby releasing the wires.

[0077] (4) Locking mechanism: By inserting or removing the locking components 3 (locking rod 33, abutment rod 32), the mounting roller 2 can be fixed in the required position to prevent it from rotating on its own, thereby maintaining the clamping state of the wire. Pulling out the locking rod 33 will release the lock and allow for readjustment.

[0078] Compared with the prior art, this application has the following advantages:

[0079] (1) Protect the electrical connection: effectively clamp the wires to avoid dragging and loosening of the meter connection caused by the weight of the wires or wind swings, and ensure the long-term stability of the connection between the meter and the wires.

[0080] (2) Easy to operate: The installation roller 2 can be easily rotated with a hex wrench for adjustment. The design of the locking component 3 makes it very convenient to fix and release the clamping state, which is convenient for the installation and replacement of wires.

[0081] (3) Stable transmission: Synchronous gears 22 are set at both ends of the mounting roller 2 to form a two-point transmission, making the synchronous movement of the two mounting rollers 2 more stable and reliable.

[0082] (4) Wire protection: The sponge sleeve on the outside of the clamping roller 21 avoids the possible damage to the wire sheath caused by rigid clamping, and plays a buffering and protective role.

[0083] (5) Stable structure: The mounting roller 2 is supported by bearings and rotates flexibly. The locking frame 31 is firmly installed on the electrical box body 1 by the fixed side lug 313, which ensures the reliability of the locking assembly 3.

[0084] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope.
