Description

Technical Field

[0001] The utility model relates to the technical field of line potting, in particular to a wire outlet potting structure of a photoelectric direct-reading water meter head. Background Art

[0002] The meter head of a photoelectric direct-reading water meter requires potting at the wire outlet hole. Currently, there are two common potting methods for this type of meter head: 1. Design two rows of holes inside the meter, through which individual wires pass, then use a pressure block to hold the entire meter down and then fill with glue; 2. Create a single, runway-shaped, long hole inside the meter, through which the wires pass, then use a pressure block to hold the entire meter down and then fill with glue. Both potting methods result in glue overflow and cannot guarantee a tight seal.

[0003] In view of this, this application is hereby filed. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing wire outlet hole potting structure will have glue overflow and the sealing cannot be guaranteed. The purpose is to provide a wire outlet hole potting structure for the photoelectric direct-reading water meter head, which can not only avoid the glue overflow phenomenon, but also can well ensure the sealing of the wire outlet hole package.

[0005] The utility model is achieved through the following technical solutions:

[0006] A wire outlet potting structure for a photoelectric direct-reading water meter head includes a tray disposed on the back of the water meter head, a wire outlet potting groove formed on the surface of the tray, and an outer end of the wire outlet potting groove passing through the edge side wall of the tray and having an opening for leading out a wire;

[0007] The inner end of the outlet potting groove is provided with an outlet circular hole, and the line passes through the outlet circular hole from the inside of the meter head and is led along the outlet potting groove to the outside of the opening;

[0008] A lower clamping block is provided in the outlet potting groove, and a lower clamping groove is provided on the upper end of the lower clamping block for fixing the line led out of the outlet circular hole;

[0009] A pressing block is provided above the lower card seat block, an upper card seat block is provided on the bottom surface of the pressing block, and a card line upper groove is provided at the lower end of the upper card seat block;

[0010] The pressing block covers the lower base block, and the upper base block and the lower base block are tightly fitted to clamp the circuit, separating the side where the inner end of the outlet potting groove is located to form a potting cavity.

[0011] The potting structure of the present invention achieves clamping of the line and sealing of the line hole by providing a wire potting groove structure on the tray, and then, when the lower and upper clamping blocks are tightly fitted together, a potting cavity for glue potting is formed between the wire potting groove and the wire potting groove. During assembly, the line first passes through the wire hole and is inserted into the wire potting groove. Then, the pressing block is covered on the lower clamping block, so that the grooves of the upper and lower clamping blocks tightly engage the line, achieving a good seal. Potting glue is then injected into the potting cavity, and assembly is completed after solidification. Due to the coordinated arrangement of the upper and lower clamping blocks, glue overflow can be avoided, while also ensuring the sealing between the wire potting groove and the wire potting groove and the line, thereby improving the potting quality of the wire hole.

[0012] In a specific embodiment, the diameter of the outlet circular hole is 0.08 to 0.12 mm larger than the diameter of the line, which can facilitate the line to pass through the outlet circular hole.

[0013] In a specific embodiment, the line clamping groove and the line clamping groove are semicircular arc structures. The line clamping groove and the line clamping groove are combined and spliced ​​to form a circular clamping groove. The diameter of the line clamping groove and the line clamping groove is 0.08 to 0.12 mm smaller than the line diameter, which can achieve reliable fixation and sealing of the line by the line clamping groove and the line clamping groove.

[0014] In a specific embodiment, a plurality of the wire outlet circular holes are provided along the width direction of the wire outlet potting groove.

[0015] In a specific embodiment, the cable clamping lower groove and the cable clamping lower groove are also provided in plurality, and correspond one-to-one with the cable outlet circular holes respectively.

[0016] In a specific embodiment, the lower seat block is arranged along the width direction of the outlet potting groove and its two ends extend to the two side walls of the outlet potting groove.

[0017] In a specific embodiment, the lower seat block and the outlet wire potting groove are an integrated structure.

[0018] In a specific embodiment, two parallel upper card seat blocks are provided on the pressing block, and the distance between the two upper card seat blocks matches the thickness of the lower card seat block; when covering the lower card seat block, the lower card seat block is clamped between the two upper card seat blocks.

[0019] In a specific embodiment, both ends of the pressing block are detachably fixed to the trays on both sides of the outlet potting groove.

[0020] In a specific embodiment, fixing holes are provided at both ends of the pressing block, threaded holes are provided on the trays on both sides of the outlet potting groove, and the pressing block is fastened to the tray by screws.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

By providing a wire outlet potting groove structure on a tray, and then by closely fitting the lower and upper clamping blocks together, the wires are clamped and the wire holes are sealed. At the same time, a potting cavity for glue filling is formed between the wire outlet potting groove and the wire outlet potting groove.

[0023] 2. The embodiment of the present invention provides a wire outlet hole sealing structure for a photoelectric direct-reading water meter head. During assembly, the line first passes through the wire outlet circular hole and is inserted into the wire clamping groove. Then, the pressing block is covered on the lower base block, so that the clamping grooves of the upper base block and the lower base block tightly clamp the line to achieve a good seal. Then, potting glue is injected into the potting cavity, and the assembly is completed after solidification. Due to the coordinated arrangement of the upper base block and the lower base block, glue overflow can be avoided. At the same time, the sealing between the wire clamping groove and the wire clamping groove and the line is guaranteed, thereby improving the quality of the wire outlet hole sealing.
