Abstract
The utility model provides a novel plastic lead seal which is mainly used in the field of electric meters. In the utility model, a matching boss is arranged below the upper end surface of the plastic lead seal; an electric energy meter cover and a base are fixed together through a sealing screw; in order to prevent the screw from being unscrewed by an unauthorized person, the plastic lead seal cover is pressed into a lead sealing hole of the electric energy meter cover from the upper part of the lead sealing screw; the external diameter of the matching boss is slightly larger than the internal diameter of the lead sealing hole of the electric energy meter cover, so the plastic bearing capacity at the periphery of the lead sealing hole of the electric energy meter cover is reinforced, and the cracking phenomenon of plastics at the periphery of the lead sealing hole of the electric energy meter cover can be avoided; and the dimensional precision requirements on the lead sealing hole of the electric energy meter cover is reduced, the qualification rate is improved and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of novel plastics lead sealing, especially has the plastics lead sealing that cooperates boss, and it is mainly used in the ammeter field.
Background technology
At present; Known plastics lead sealing cooperates with the table lid to be adopted as hard as the way that is full of, and in plastics lead sealing push table lid lead seal hole, such connection causes the aperture size of plastics lead sealing external diameter and Biao Gai lead seal hole to require very high; Increased the difficulty and the cost of processing, and the qualification rate of product is reduced.Simultaneously; The plastics lead sealing has been placed on the upper surface of showing to cover lead seal hole with the stress surface that combines that table covers lead seal hole; Cause the stress that table covers the lead seal hole upper surface to concentrate easily; Interference causes that greatly easily table covers the peripheral plastics cracking phenomena of lead seal hole, and interference is little to cause that easily the plastics lead sealing comes off, and does not reach anti-electricity-theft effect.
Summary of the invention
The utility model has overcome existing plastics lead sealing processing technology has been required and the too high shortcoming of cost, and has avoided table to cover the peripheral plastics of lead seal hole phenomenon easy to crack, provides a kind of novel band to cooperate the plastics lead sealing of boss.
Technical scheme of the present invention is that the plastics lead sealing is provided with the cooperation boss, cooperates boss to be located at the below of plastics lead sealing upper surface.Electric energy meter table lid and bottom seat is turned on by access by unauthorized persons in order to prevent screw, above the lead sealing screw through the lead sealing screw retention together; Plastics lead sealing lid is pressed in the lead seal hole that the people shows to cover, and the outside dimension that cooperates boss is greater than the plastics lead sealing, during plastics lead sealing push table lid lead seal hole; The plastics lead sealing cooperates boss to receive inside extruding force, owing to cooperate boss below plastics lead sealing upper surface, after being squeezed; Self is to internal strain; The reacting force of the peripheral plastics of his-and-hers watches lid lead seal hole reduces, and the stressed position of showing simultaneously to cover lead seal hole makes table cover the peripheral plastics ability to bear of lead seal hole and strengthens below table covers the lead seal hole upper surface.
Compared with prior art, the beneficial effect one of the utility model is that the plastics lead sealing is provided with the cooperation boss, makes table cover the peripheral plastics ability to bear of lead seal hole and strengthens, and avoids showing to cover the phenomenon of the peripheral plastics cracking of lead seal hole; The 2nd, because the oriented enterolithic characteristic of plastics lead sealing self, the magnitude of interference of cooperation can amplify, and has reduced the dimension precision requirement of showing to cover lead seal hole, has improved qualification rate, has reduced production cost.
Description of drawings
A utility model name is called the patented claim of " a kind of novel plastics lead sealing ", and its instructions comprises three width of cloth accompanying drawings, and the description of drawings of these accompanying drawings is following:
Among the figure: 1. plastics lead sealing, 2. cooperate boss, 3. table lid, 4. base, 5. lead sealing screw,
Fig. 1 is plastics lead sealing lid sectional view
Fig. 2 is plastics lead sealing and the wiring layout of showing lid
Fig. 3 is that Fig. 2 is at the A-A of lead sealing position sectional view.
Fig. 4 is the schematic perspective view of plastics lead sealing
Embodiment
Below in conjunction with accompanying drawing and practical implementation method the present invention is described in further detail:
Plastics lead sealing 1 is provided with and cooperates boss 2, cooperates boss 2 to be located at the below of plastics lead sealing 1 upper surface.Table cover 3 and base 4 be fixed together through lead sealing screw 5, turned on by access by unauthorized persons in order to prevent lead sealing screw 5, above lead sealing screw 5; In the lead seal hole with plastics lead sealing 1 lid push table lid, it is bigger to cooperate boss 2 outside dimensions to cover 3 lead seal hole internal diameters than table, when plastics lead sealing push table is covered 3 lead seal holes; The plastics lead sealing cooperates boss 2 to receive inside extruding force; Because cooperate boss 2 below plastics lead sealing 1 upper surface, after being squeezed, self is to internal strain; The reacting force of the peripheral plastics of his-and-hers watches lid lead seal hole reduces; The stressed position of showing simultaneously to cover lead seal hole makes table cover the peripheral plastics ability to bear of lead seal hole and strengthens below table covers the lead seal hole upper surface, avoids showing to cover the phenomenon of lead seal hole periphery plastics cracking.Because the oriented enterolithic characteristic of plastics lead sealing 1 self, the magnitude of interference of cooperation can amplify, and has reduced the dimension precision requirement that table covers lead seal hole, has improved qualification rate, has reduced production cost.
