Abstract
The utility model relates to an anti-theft lock which is used for tap water meters and gas meters. The anti-theft lock adopts an open type monomer protective sheath structure. A visual protective lock is positioned and fixed in a pinna of the opening of a protecting cover. A protective lock is in a lead seal mode with a fixed sealing line and double lock points and is positioned and fixed in the pinna of the protective sheath by disposable rivets. Therefore, the anti-theft lock can not be opened if no destructive measure is taken. Thus, the utility model fundamentally solves the problems of less lock points on lead seal and easily detached outlaid surface seal, existing on the existing anti-theft devices, and enables energy loss which is caused by that a metering device is inversely placed, and limited water and gas resources in China to be used with compensation.
Description
The utility model belongs to utility measuring instrument anti-theft device technical field, is specifically related to a kind of theftproof lock that is used for tap water, gas measurement instrument.
In the people's daily life, the charge of tap water, coal gas is measured by water meter, gas meter.But find that in actual use indivedual people reach less the purpose of paying dues, not paying dues, take to tear open improper means pilferage tap water or coal gas such as table upside-down mounting without authorization.Do that so national water, gas resource and water supply, the interests of air feed enterprise are incurred loss, also threatened the safety of people's lives and properties simultaneously.For addressing the above problem, some water supply, air feed specialized company have adopted plastics binary measuring instrument protective device in order to strengthen the measuring control to tap water, coal gas.But find that in use plastics binary measuring instrument protective device volume is big, install inconvenient, poor durability, especially its uses remains external gauge seal, split easily moving, so antitheft effect is undesirable.In addition, also having a kind of coal gas anti-theft device is to adopt the abrasive paper seal to be encapsulated in the movable joint place of gas meter, comes off easily after making moist, so popularity rate is very low at present.
The purpose of this utility model provides a kind of utility meter theftproof lock that is installed on utility meter movable joint place, makes it fundamentally stop to tear the generation that measuring instrument is stolen water, stolen the gas situation without authorization open, reduces energy loss.
The utility model is achieved in that the utility meter theftproof lock adopts open type monomer protective jacket structure, is fixed with visual Protective lock in that the ear of its protective jacket opening part is built-in.Visual Protective lock is the twin-lock point lead sealing of fixed sealing line, with the built-in ear of being fixed in the protective jacket opening part of Protective lock, therefore, uses the non-destructive measure can't open this theftproof lock with disposable rivet.
When the utility model uses it is sleeved on the movable joint place that is connected with water meter or gas meter, is that twin-lock point lead sealing couple together with gauging table head, watchcase and gauging table and 3 of pipeline junctions with visual Protective lock with the envelope line, use disposable rivet technology with the built-in ear of being fixed in the protective jacket opening part of Protective lock, use the non-destructive measure can't open this theftproof lock, it is few thoroughly to have solved existing protective device lead sealing lock point, external gauge seal is torn open easily, the energy loss that makes measuring instrument be squeezed to cause.Use the utility model, can play the user and use relievedly, supply water, air feed department uses relieved effect, thereby avoided tap water, the stolen incident of coal gas to take place, make national limited water resource, combustion gas resource obtain paid utilization, improve the economic benefit of water supply, air feed department.
Below in conjunction with accompanying drawing embodiment of the present utility model is done following explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the Protective lock structural representation among Fig. 1;
Fig. 4 is the vertical view of Fig. 3.
Among the figure, protective jacket 1 is a reducing through type opening protective jacket, and thickness is 0.4-0.8mm, with stainless steel or plastic production.Its protective jacket opening part has ears, and visual Protective lock 2 is clipped in the ears of protective jacket opening part.On the ears of Protective lock 2 and protective jacket, rivet hole is all arranged, with Protective lock 2 built-in ears of being fixed in the protective jacket opening part, like this, do not take destructive measure can't open this theftproof lock with disposable self-plugging rivet 3.Protective lock 2 is the twin-lock point lead sealing of fixed sealing line; Lead sealing can be made cuboid or triangle, envelope line perforation 4 is arranged on it, after the envelope line that penetrates lead sealing after will measure gauge outfit, watchcase and gauging table and 3 of pipeline junctions being connected with the envelope line during use is bored a hole, be fixed in purpose, the function that protective jacket ear can realize this theftproof lock with Protective lock 2 is built-in with disposable rivet 3.
Claims (3)
1, a kind of utility meter theftproof lock is characterized in that this theftproof lock adopts open type worker's monomer protective jacket (1) structure, at the built-in Protective lock (2) that is fixed with of the ear of its protective jacket (1) opening part.
2, utility meter theftproof lock according to claim 1 is characterized in that described Protective lock (2) is the twin-lock point lead sealing of fixed sealing line.
