Description

Technical Field

[0001] This application relates to the field of electricity meter technology, and more specifically, to an electricity meter plug-in housing. Background Technology

[0002] An electricity meter is a measuring instrument used to measure the total amount of electrical energy consumed by a circuit within a specific time period. By sensing the voltage and current in the circuit and combining this with the time of electricity consumption, the meter processes the information and ultimately displays the result of the total amount of electrical energy consumed.

[0003] In related technologies, for example, the prior art patent with publication number CN221303403U provides an energy meter. This device is equipped with a locking plate and a locking hook. When it is necessary to disassemble the outer casing, the fixing rod is first pulled out through the handle, and then the outer casing is pulled outward. At this time, the locking plate drives the extension plate to move outward, while squeezing the arc plate, causing the spring to contract until the arc plate leaves the locking hook, thereby completing the disassembly of the outer casing. Therefore, no screwdriver is needed for disassembly and installation, and it can be applied to different spaces, making maintenance and replacement faster and simpler.

[0004] Although the existing technical solutions mentioned above facilitate the installation and disassembly of the outer casing through the locking plate and locking hook, the arc plate is squeezed when it is engaged with the locking hook. Since the locking hook is fixed to the locking plate, it is easy to be damaged by the squeezing after a long period of use (such as aging or deformation, especially for non-metallic outer casings), which leads to the scrapping of the electricity meter casing and its inability to continue to be used.

[0005] In view of this, we propose a plug-in housing for an electricity meter. Utility Model Content

[0006] The purpose of this application is to provide a plug-in housing for an electricity meter that can effectively solve the problem in the prior art where the locking hook is easily damaged by compression after long-term use, resulting in the electricity meter housing becoming unusable.

[0007] This application provides a plug-in housing for an electricity meter, comprising:

[0008] Front housing;

[0009] The rear housing is located outside the front housing, and insertion holes are provided on both sides of the rear housing;

[0010] The latch is slidably located on the inside of the front housing;

[0011] Two sliding plates are provided on the inner side of the front housing. The top of the sliding plate extends to the top of the front housing and is slidably disposed with the front housing, for driving the pin to be inserted into the inner side of the corresponding socket.

[0012] As an optional solution to the technical solution of this application, the top and bottom of the front housing are provided with sliding openings, the sliding openings are slidably configured with corresponding sliding plates, and the outer side of the front housing is provided with a mating groove corresponding to the pin.

[0013] As an optional solution to the technical solution of this application, fixing blocks are fixedly provided on both sides of the rear housing, and the insertion hole is opened on the inner side of the fixing block.

[0014] As an optional solution to the technical solution of this application, the end of the pin is set to be tapered, and the inner side of the socket is set to be tapered corresponding to the pin.

[0015] As an optional solution of the technical solution in this application, a sliding pin is fixedly provided on the outer side of the pin, and an oblique hole is opened on the sliding plate corresponding to the sliding pin. The sliding pin is slidably disposed with the oblique hole. When the sliding plate is lifted by an external force, it drives the sliding pin to move. The pin is slidably disposed on the inner side of the sliding sleeve, and the sliding sleeve is fixedly disposed with the inner side of the front housing.

[0016] As an optional solution to the technical solution of this application, a connecting rod is fixedly provided on the top of both slide plates. The connecting rod is rotatably disposed on the outside of the bolt, and the bolt is threaded to the top of the front housing.

[0017] As an optional solution to the technical solution of this application, the top of the front housing is provided with a threaded hole, and the threaded hole is threaded with a bolt.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) This application uses a pin and a socket. The pin and the socket are driven by a sliding plate to fix the front shell and the rear shell. This effectively solves the problem in the prior art that the locking hook is easily damaged by squeezing after long-term use, which leads to the scrapping of the electricity meter shell and the inability to continue to use it. It achieves the effect of installing and disassembling the shell by plugging.

[0020] (2) By setting the end of the pin and the inner wall of the socket to be tapered, this application has a higher tolerance for the machining dimensional error of the pin and the socket, reducing production requirements. By setting a fixing block, the socket is opened on the outside of the fixing block, which increases the strength of the rear housing. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This application discloses an electric meter plug-in housing, including a front housing 1, a rear housing 2 on the outside of the front housing 1, and plug holes 21 on both sides of the rear housing 2. A pin 3 is slidably disposed on the inside of the front housing 1, and two sliding plates 4 are disposed on the inside of the front housing 1. The top of the sliding plates 4 extends to the top of the front housing 1 and is slidably disposed with the front housing 1 to drive the pin 3 to be inserted into the inside of the corresponding plug hole 21.

[0029] When installing the outer casing, the front casing 1 is slid to the inside of the rear casing 2. The slide plate 4 moves downward under external force, driving multiple pins 3 to slide, so that the pins 3 cooperate with the corresponding holes 21, thereby fixing the front casing 1 and the rear casing 2. When disassembling the outer casing, the slide plate 4 moves in the opposite direction, causing the pins 3 to slide out from the inside of the holes 21, releasing the fixation, and allowing the front casing 1 to slide out from the inside of the rear casing 2, which facilitates the installation and disassembly of the outer casing.

[0030] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The front housing 1 has sliding openings 11 at both the top and bottom. The sliding openings 11 are slidably disposed with the corresponding sliding plates 4. The outer side of the front housing 1 has a mating groove 13 corresponding to the pin 3. The outer side of the pin 3 is fixedly disposed with a sliding pin 31. The sliding plate 4 has an oblique hole 41 corresponding to the sliding pin 31. The sliding pin 31 is slidably disposed with the oblique hole 41. When the sliding plate 4 is lifted by external force, it drives the sliding pin 31 to move. The pin 3 is slidably disposed inside the sliding sleeve 32. The sliding sleeve 32 is fixedly disposed inside the front housing 1. The top of the two sliding plates 4 is fixedly disposed with a connecting rod 42. The connecting rod 42 is rotatably disposed outside the bolt 43. The bolt 43 is threaded to the top of the front housing 1. The top of the front housing 1 has a threaded hole 12. The threaded hole 12 is threaded to the bolt 43.

[0031] When installing the outer casing, by rotating the bolt 43, the bolt 43 is engaged with the threaded hole 12, which drives the connecting rod 42 to move downward, thereby driving the slide plate 4 to move downward, so that the inclined hole 41 and the sliding pin 31 cooperate and slide, thereby driving the pin 3 to slide inside the sliding sleeve 32, so that the pin 3 is tightly fitted with the corresponding insertion hole 21, completing the fixing of the front casing 1 and the rear casing 2. After the fixing is completed, the bottom of the bolt 43 is stored inside the front casing 1 to reduce the space occupied.

[0032] When disassembling the outer casing, rotate the bolt 43 in the opposite direction to move the pin 3 out from the inside of the socket 21.

[0033] Reference Figure 5 Both sides of the rear housing 2 are fixedly provided with fixing blocks 22, and the insertion hole 21 is opened on the inner side of the fixing block 22.

[0034] By setting the fixing block 22, the insertion hole 21 is opened on the inner side of the fixing block 22. When fixed, the fixing block 22 is subjected to force, which increases the strength of the rear shell 2.

[0035] Reference Figure 2 and Figure 5 The end of the pin 3 is tapered, and the inner side of the socket 21 is tapered corresponding to the pin 3.

[0036] By setting the end of the pin 3 and the inner wall of the socket 21 to be tapered, the tolerance for machining dimensional errors of the pin 3 and the socket 21 is higher, and the production requirements are reduced.

[0037] In summary, during installation, the electricity meter plug-in housing disclosed in this application slides the front housing 1 to the inside of the rear housing 2. By rotating the bolt 43, the bolt 43 engages with the threaded hole 12, causing the connecting rod 42 to move downward, thereby causing the sliding plate 4 to move downward. This allows the inclined hole 41 and the sliding pin 31 to engage and slide, thereby causing the plug pin 3 to slide inside the sliding sleeve 32, so that the plug pin 3 is tightly fitted with the corresponding plug hole 21, thus fixing the front housing 1 and the rear housing 2.

[0038] When disassembling the outer casing, the bolt 43 is rotated in the opposite direction to allow the pin 3 to slide out from the inside of the insertion hole 21, thereby releasing the fixation and allowing the front casing 1 to slide out from the inside of the rear casing 2, thus completing the disassembly of the front casing 1 and the rear casing 2.
