[0002] The concentrator is a key component of a low-voltage centralized meter reading system. As the central link in the system, it is installed on the low-voltage side of a low-voltage distribution transformer. It automatically reads and stores power data from various smart meters, data collection terminals, or data collection modules with carrier or RS485 communication capabilities via downlink channels. It transmits this data to power supply and utilization management departments on a scheduled or real-time basis via public telephone lines, GPRS, CDMA, Ethernet, or infrared handheld meter readers. It is primarily used in locations requiring centralized meter reading, such as power companies, public utilities, public buildings, and residential communities. It is typically used in conjunction with a master station in a low-voltage centralized meter reading system.

[0003] The existing concentrators have the following problems during use:

[0004] Currently, concentrators are mainly installed by hanging, which results in a relatively simple installation method for the concentrator. In addition, the installation method cannot be changed according to the actual installation environment during installation of the concentrator, which makes the concentrator difficult to install when it cannot be hung.

[0009] When using the concentrator of the present technical solution, the fixing bolt can be rotated to the outside of the threaded groove, and the side strip is pulled away from the concentrator body. When the side strip is pulled out, the fixing bolt can be rotated in the opposite direction. When the fixing bolt is rotated in the opposite direction, it can move to the inside of the threaded groove and press the side strip, so that the concentrator body can be installed through the mounting hole on the surface of the side strip.

[0010] Preferably, the side strips are slidably connected to the fixing bolts through the strip grooves. When the side strips are subjected to tension, the limiting hooks can be driven to slide on the surface of the limiting strips, thereby limiting the movement direction of the side strips.

[0011] Furthermore, the fixing bolt and the thread groove are threadedly connected, and the fixing bolt can move toward the outside of the thread groove when it rotates inside the thread groove, and at this time the side strip can be pulled to slide.

[0012] Furthermore, the limiting hook and the limiting strip are slidably connected, and the side strip can drive the strip groove to slide on the surface of the fixing bolt, so that the position of the side strip can be adjusted.

[0013] Furthermore, a fixing hole is opened at the end of the protective cover, a rotating shaft passes through the surface of the concentrator body, a fixing hook is connected to the middle of the rotating shaft, a spring bar is connected between the fixing hook and the concentrator body, and the spring bar is sleeved on the surface of the rotating shaft.

[0014] Furthermore, a snap-fit ​​structure is formed between the fixing hook and the fixing hole, and the position of the protective cover is fixed by snapping the fixing hook and the fixing hole, thereby achieving closure of the protective cover.

[0015] Furthermore, the fixed hook forms a rotating structure with the concentrator body through the rotating shaft, and the fixed hook forms an elastic reset structure with the spring bar.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model can move toward the outside of the threaded groove when the fixing bolt is rotated. At this time, pulling the side strip in the direction away from the concentrator body can drive the limit hook to slide on the surface of the limit strip. At the same time, the side strip can drive the bar groove to slide on the surface of the fixing bolt. When the side strip is pulled out, the fixing bolt can be rotated in the opposite direction. When the fixing bolt is rotated in the opposite direction, it can move toward the inside of the threaded groove. In this way, the side strip can be pressed tightly by the fixing bolt, so that the concentrator body can be installed through the mounting hole on the surface of the side strip. In this way, the concentrator body can be installed in various ways according to the installation environment of the concentrator.

[0019] The utility model can facilitate the opening and closing of the protective cover by arranging the fixing hole, the rotating shaft, the fixing hook and the spring bar. Compared with the existing fixing method by bolts, no additional tools are required and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Working principle: When using the device of the present technical solution, when installing the concentrator body 1, first rotate the fixing bolt 8. When the fixing bolt 8 rotates inside the thread groove 9, it can move toward the outside of the thread groove 9. At this time, the side strip 5 can be pulled in the direction away from the concentrator body 1. When the side strip 5 is subjected to tension, it can drive the limiting hook 10 to slide on the surface of the limiting strip 11. At the same time, the side strip 5 can drive the strip groove 7 to slide on the surface of the fixing bolt 8.
