Abstract
The utility model relates to a connection structure between an electric meter cover and a case cover. The connection structure is characterized in that the electric meter cover is provided with a U-shaped edge; a downward bulge is arranged at a reserved opening of the case cover, matched with the electric meter cover; the bulge is inserted into a groove of the U-shaped edge; fixing jaws extending outwards are respectively and integrally arranged at four corners of the U-shaped edge; and a columnar bulge connected with the fixing jaw is arranged at the part on the case cover, close to the reserved opening. Since the bulge at the reserved opening of the case cover is inserted into the groove of the U-shaped edge of the electric meter cover, the connection structure improves the tightness of the case cover and the electric meter cover at the combining part, and effectively prevents dust and rain from entering a case, thus prolonging the service life of equipment; and the matching of the fixing jaw on the electric meter cover and the columnar bulge on the case cover ensures firm connection between the electric meter cover and the case cover, and improves the damage resistance of the equipment.
Description
Technical field
The utility model relates to the cover structure of ammeter box, particularly the syndeton between watthour meter cover and the case lid.
Background technology
At present, the wall-hanging ammeter box of outdoor use is made of casing and the case lid that is mated, elements such as ammeter, switch, line row are arranged in the casing, the position corresponding with ammeter is provided with transparent watthour meter cover 2 on case lid 1, the lower end of watthour meter cover is provided with along circumferential projection 8, this projection is embedded in the preformed hole on the case lid, along several grabs 9 that is circumferentially with of projection, is used for limiting watthour meter cover moving perpendicular to the case lid direction.The watthour meter cover of said structure has characteristics easy for installation, but poor sealing performance, when being applied to abominable external environment, sand and dust or rainwater can enter into along the binding site of watthour meter cover and case lid in the casing, cause internal short-circuit, components and parts damage, and reduce the serviceable life of equipment.
Summary of the invention
The utility model provides the watthour meter cover of a kind of compact conformation, good airproof performance, dustproof and rainproof and the syndeton between the case lid for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Syndeton between a kind of watthour meter cover and the case lid, it is characterized in that: described watthour meter cover is provided with U type edge, the reserved opening place that cooperates with watthour meter cover on the case lid is provided with downward projection, described projection is inserted in the groove at described U type edge, Si Jiaochu at described U type edge is integrally formed with outward extending fixed claw, and the position near preformed hole on case lid is provided with the columnar projections that is connected with described fixed claw.
Advantage and the good effect that the utlity model has are:
Be inserted into by projection in the groove at watthour meter cover U type edge, improved case lid and watthour meter cover sealing, can effectively avoid dust and rainwater to enter the inside of casing, thereby improve the serviceable life of equipment at binding site with case lid reserved opening place; The cooperating of columnar projections on fixed claw and the case lid guarantees that watthour meter cover and the firm of case lid are connected, and have improved the anti-destructive of equipment on the watthour meter cover.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cut-open view;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is the structural representation of watthour meter cover;
Fig. 5 is the partial schematic diagram of the syndeton of case lid and watthour meter cover in the prior art.
Among the figure: 1, case lid; 2, watthour meter cover; 3, U type edge; 4, groove; 5, projection; 6, fixed claw; 7, columnar projections; 8, projection; 9, grab.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-4, syndeton between a kind of watthour meter cover and the case lid, watthour meter cover 2 is provided with U type edge 3, the reserved opening place that cooperates with watthour meter cover on the case lid 1 is provided with downward projection 5, described projection is inserted in the groove 4 at described U type edge, Si Jiaochu at described U type edge is integrally formed with outward extending fixed claw 6, and the position near preformed hole on case lid is provided with the columnar projections 7 that is connected with described fixed claw.Particularly, on fixed claw, be provided with via hole, on columnar projections, be provided with screw hole, fixed claw is pressed on the lower surface of columnar projections from the inboard of case lid, case lid reserved opening place in lower convexity is inserted into the groove at U type edge, by screw fixed claw is fixedlyed connected with columnar projections.
To sum up, be inserted into by projection in the groove at watthour meter cover U type edge, improved case lid and watthour meter cover sealing, can effectively avoid dust and rainwater to enter the inside of casing, thereby improve the serviceable life of equipment at binding site with case lid reserved opening place; The cooperating of columnar projections on fixed claw and the case lid guarantees that watthour meter cover and the firm of case lid are connected on the watthour meter cover, because case lid is arranged on case lid inside with being connected of watthour meter cover, the while has also been improved the anti-destructive of equipment.
