Abstract
The utility model discloses an environmental protection seal, characterized in that the environmental protection seal comprises a concave seat which is provided with a flute; a plunger piston is arranged in the flute; sealed strand through holes are arranged on the concave seat and the plunger piston correspondingly; tangent planes are arranged on the outside walls near the through holes on both sides of the plunger piston; and sealed strands are arranged in the sealed strand through holes of the concave seat and the plunger piston. Since the utility model is made of rigid polyvinyl chloride or ABS engineering plastics and provided with structures such as the concave seat, the flute, the plunger piston, etc., the toxic hazard of the original lead seal can be avoided, the cost is low and the operation is convenient. Different colors can be adopted on each batch of seals to distinguish the year of the instrument leaving the factory, which is convenient for the supervision and management of the production checking unit.
Description
Technical field
The utility model relates to envelope civilian and industrial instrument such as a kind of water meter, gas meter, flow meter, watt-hour meter, tensimeter and remembers.Be specifically related to a kind of Environmental protection seal.
Background technology
Various instrument must add all that after calibration the envelope note is as protection.Just can not take instrument apart or change its adjusting gear as not destroying this protective device, guarantee the fairness of commerce and trade clearing and the Technical responsibilities of drawing a clear instrument fabricator and user with this.The envelope note comes down to a special lock, but does not wear key, can only use once.
Extensively adopt plumbous matter envelope note at present, its ultimate principle is that the housing of instrument and enclosing cover are enclosed within on the fine rule (copper cash, nylon wire), the two ends of fine rule are inserted in the hole of special lead, with the pliers that has steel seal fine rule and lead extruding are fixed together at last.Do not press tightly and fine rule can be extracted out but squeeze sometimes, so that to cause disagreement.
Lead is the non-ferrous metal of severe toxicity, and the press compositor deeply hurt in the past, had adopted laser phototypesetting technology now, has taken leave of harm plumbous and fire, and gasoline also changes unleaded gasoline into.Lead sealing is disadvantageous to the instrument workers'health, particularly is installed in the lead sealing of the domestic water meter of every family, more may endanger the health even the life security of young child.
The seal product that has occurred at present multiple non-plumbous matter in the society, but its complex structure costs an arm and a leg, each 0.5 yuan～3 yuan, and the price of lead sealing has only 0.03 yuan～0.05 yuan, thereby be difficult to promote.
Summary of the invention
The purpose of this utility model just is to provide a kind of with low cost, easy to use and nontoxic Environmental protection seal.
The purpose of this utility model can realize by following measure:
The utility model comprises dimple, dimple is provided with groove, be provided with plunger in groove, correspondence offers the envelope line three-way hole on dimple and plunger, is provided with the envelope line being provided with on the lateral wall of through hole, plunger both sides in the envelope line three-way hole of tangent plane at dimple and plunger.
Dimple in the utility model and groove and plunger are cylindrical or are rectangle, and certainly, dimple, groove and plunger also can adopt rectangle or other suitable shapes.The envelope line three-way hole is an elliptical shape.The envelope line three-way hole is a through hole.The envelope line three-way hole is two through holes arranged side by side.Groove on plunger and the dimple is contour.Plunger and dimple all adopt rigid polyvinyl chloride or ABS engineering plastics to make, and also can adopt other suitable material.Plunger and dimple are provided with pattern or indenture.Be attached with color on plunger and the dimple.In addition, the tangent plane on the plunger lateral wall also can be the ring surface face.The design tangent plane is to form the gap for making between plunger middle part and the groove.
The utility model is owing to adopt dimple and structures such as groove, plunger, and adopts rigid polyvinyl chloride or ABS engineering plastics to make, and made it to avoid the murder by poisoning of original lead sealing, and cost is very cheap simultaneously, and easy to use firm.Also can adopt different colors to distinguish the age that instrument is dispatched from the factory, convenient supervision and management of making verification unit by each batch envelope note.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises dimple 4, dimple is provided with groove, in groove, be provided with plunger 2, plunger and groove are wringing fit, and correspondence offers envelope line three- way hole 6,7 on dimple 4 and plunger 2, is provided with tangent plane on the lateral wall of through hole, plunger 2 both sides, be provided with envelope line 1 in the envelope line three- way hole 6,7 of dimple 4 and plunger 2, the envelope line can adopt common fine rule.Dimple 4 and groove are cylindrical.Plunger 2 is cylindrical.Envelope line three- way hole 6,7 is an elliptical shape.Envelope line three- way hole 6,7 is a through hole.Envelope line three- way hole 6,7 is two through holes arranged side by side.Plunger 2 is contour with the groove on the dimple 4.Plunger 2 all adopts rigid polyvinyl chloride or ABS engineering plastics to make with dimple 4.Plunger 2 is provided with pattern or indenture with dimple 4.Be attached with color on plunger 2 and the dimple 4.Specifically: as shown in drawings, the fabricator accurately inserts dimples 4 to plunger 2 with the batch assembling method in advance by the envelope note, and their oval eyelet 6 and 7 is aimed at.Supply in full sets is given instrument check unit then.
Principle of work of the present utility model is as follows: instrument check unit is when work, earlier entangle the housing and the enclosing cover of instrument with fine rule 1, with in 1 the two ends and neat insertion eyelet 6 and 7, with common hand vice plunger 2 is pressed into dimple 4 more then, reaches till cavity 5 complete obiterations.This moment, plunger 2 flushed with the end face of dimple 4, and because of bigger friction force is arranged between them, so plunger 2 can not take out from dimple 4.In the end fine rule 1 becomes the shape of 4 90 ° of elbows, and fine rule 1 firmly clamp-oned for twice in the arc slit 3 of plunger 2, and the straight warp of fine rule 1 is 0.6mm, and the width in gap 3 is 0.2mm, and fine rule 1 distortion that is crushed is so fine rule 1 can not be extracted out from dimple 4.Plunger 2 and dimple 4 all are compression moldings in enormous quantities, thereby cheap.
On the outside surface of plunger 2 and dimple 4, can go out spill literal and pattern by the requirement mold pressing of verification unit, and select the color of material in batches.
The fine rule two ends that the utility model will seal note are pressed in the fastener of particular design, and it can't be extracted out, reach reliable effect; The age that each batch plastics envelope note adopts different colors to dispatch from the factory with the difference instrument, convenient supervision and management of making verification unit.
