Abstract

The utility model relates to a water and gas meter dismantling prevention shackle, which belongs to the technical field of water and gas meter installation. The utility model is characterized in that semicircles 1 and 2 are connected together by a chain 3, one end of the semicircle 2 is provided with an inverted tongue 6, the corresponding position of the semicircle 1 is provided with an eyelet 5, and the inverted tongue 6 can be plugged into the eyelet 5. The utility model has the advantages that the shackle is made of thinner PVC or plastic material and is sheathed on a nut of an interface of a meter; the inverted tongue 6 is sheathed into the eyelet 5 when the utility model is installed; the inverted tongue is plugged tighter and tighter; only when a dismantling handle is pulled down by hand, the utility model can be dismantled, therefore, the utility model can only be used once; the secret water and gas meter dismantling for users can be prevented effectively; the utility model has the advantages of simple structure, low cost and convenient mounting and operation.

Description

Water meter, gas meter, flow meter dismantling prevention snap close

One, technical field

The utility model belongs to water meter, gas meter, flow meter field engineering field.

Two, background technology

Water meter, gas meter, flow meter are the gauging tables that metering user makes water and coal gas, natural gas, no matter are the domestic consumers, or enterprises and institutions, and all the numeral of regularly being walked with the table tool is to water supply, and air feed unit submits expense.Coal gas not only can be made for meal, has a bath, and also can warm oneself, and usable range is increasing, and gas consumption also strengthens gradually; The consumption of water in daily life, production is also very big.The user who has is for many waters or coal gas and the usefulness of paying dues less in use will be shown tool to pull down privately, and with two joint upside-down mountings, formal dress again when waiting to look into gas meter and water meter personnel and regularly consulting has seriously disturbed the normal meterage of tap water and coal gas.In order to prevent that above-mentioned phenomenon from taking place, seal with dismantling prevention the import junction (meter connector) that employing aluminium bundle bar that present administrative authority has and heat-shrink tube will be shown tool, makes complexity but do exercises like this, also need be with the operation of thermal source or naked light, does not meet safety regulation for operations.

Three, summary of the invention

The purpose of this utility model provides a kind of water meter, gas meter, flow meter dismantling prevention snap close, can prevent user dismounting water meter, gas meter, flow meter privately easily.

The utility model is achieved in that water meter, gas meter dismantling prevention snap close, and semicircle 1 and 2 links together by chain 3, is provided with pawl tongue 6 at an end of semicircle 2, is provided with buttonhole 5 at the correspondence position of semicircle 1, and pawl tongue 6 can be inserted in the buttonhole 5; On semicircle 1, also be provided with orcible entry 4.Leave the gap after semicircle 1 and semicircle 2 closures.

Compare with background technology, the beneficial effects of the utility model are:

1, snap close is made with thin PVC or plastic material, is sleeved on the nut of table tool interface, and pawl tongue 6 is nested in the buttonhole 5 during installation, slotting more tight more, only pull orcible entry it being pulled down,, can prevent user dismounting water meter, gas meter, flow meter privately effectively so can only disposablely use.

2, simple in structure, with low cost, fitting operation is very convenient.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is to use view;

Fig. 3 is the side view of Fig. 2.

Five, embodiment

When water meter or gas meter, flow meter installation in position, after the assay was approved, will show the water inlet of tool or the meter connector nut of air intake opening wraps with 180 ° of the semicircle 1 of snap close and 2 doublings, then pawl tongue 6 is inserted in the buttonhole 5, suitably firmly it is seated.Owing to the pawl on the pawl tongue is shaped as the narrow head breadth of transfering to of insert head, so the whole internal diameter of snap close can only dwindle, snap close will be shown the nut of tool joint and pawl tongue 6 and buttonhole and tightly encase like this.If the table tool breaks down when need changing, managerial personnel will tear downs with hand and pull down 4, because it is thinner with the coupling part materials of semicircular body to tear down handle, be easy to draw back, and whole snap close is divided into two to be pulled down.

Claims (3)

1, water meter, gas meter dismantling prevention snap close, it is characterized in that: semicircle (1) and (2) link together by chain (3), end at semicircle (2) is provided with pawl tongue (6), is provided with buttonhole (5) at the correspondence position of semicircle (1), and pawl tongue (6) can be inserted in the buttonhole (5).

2, water meter according to claim 1, gas meter dismantling prevention snap close is characterized in that: semicircle (1) is provided with orcible entry (4).

3, water meter according to claim 1, gas meter dismantling prevention snap close is characterized in that: leave the gap after semicircle (1) and semicircle (2) closure.
