Description

Technical Field

[0001] The invention belongs to the technical field of electric meter collectors, and in particular relates to a power line fixing device of an electric meter collector. Background Art

[0002] An electric meter collector is a device used to remotely collect and transmit electric meter data. Its main function is to collect electricity, power and other data from multiple electric meters, and then transmit these data to the background management system wirelessly to achieve remote monitoring and management of the electric meters. Multiple electric meters need to be connected to the collector using communication lines and terminals respectively. At the same time, the collector itself also needs power supply, and different models of collectors will use different power supply methods.

[0003] There are several ways to power the meter collector, including AC power supply, battery power supply, and solar power supply. Taking AC power supply as an example, the collector needs to use a special power adapter to convert the AC power into a low voltage suitable for the meter collector. At the same time, some collectors are equipped with rechargeable batteries to serve as a backup power source when the AC power is interrupted. The power cord between the power adapter and the collector usually needs to be curled and hung on the wall. For easy operation, the collector will be directly installed on the indoor wall in residential buildings and other places, so the power cord will be hung on the wall naked. For many animals in the city, the power cord is very easy to touch, and the outer layer of the power cord used to connect the power adapter is often made of ordinary materials. Animals repeatedly come into contact with the power cord, which is very dangerous for both the power cord and the animals. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a power line fixing device for an electric meter collector.

[0005] The technical solution adopted to solve the above technical problems is: A power line fixing device for an electric meter collector comprises a collector body, a power line body and a power adapter, wherein one end of the power line body is connected to the collector body, and the other end is connected to the power adapter, a side block is fixedly connected to the side wall of the collector body, a bottom groove is provided at the bottom of the side block, a side groove is provided on the side wall of the side block away from the collector body, both the side groove and the bottom groove are T-shaped grooves, a movable T-shaped rod is slidably connected in the bottom groove, a side T-shaped rod is slidably connected in the side groove, a lock is installed on the side wall of the side block, an inclined rod is fixedly provided on the side wall of the side T-shaped rod, and a fixed cover is fixedly connected to the bottom of the inclined rod; The fixed cover is provided with two placement grooves on the side wall facing one end of the power cord body, and the two ends of the power cord body are respectively stuck in the two placement grooves.
