When the gas meter is maintained or stolen and changed, conventional disassembling and assembling of the gas meter can only be achieved through destructive disassembling, disassembling can not be recovered, use reliability is high, and the application range is wide.
Description
Technical field
The present invention relates to the parts of a kind of flowrate measuring tool, the antitheft Plastic packaging apparatus of especially a kind of gas meter, flow meter.
Background technology
It is known that gas meter, flow meter is that in order to the accumulative flow measurement instrument flowing through the long-pending total amount of pipeline combustion gases, it is installed, counting direct relation the safety of user, economic interests.The enumerator of gas meter, flow meter is to be buckled in watchcase by table door cover, and between Biao Men with watchcase, screw is connected, the enumerator changing Biao Mennei for preventing user from privately stealing, and all have employed anti-theft device between its table door and watchcase.Formula Antitheft lead seal worn by the conventionally employed line of this anti-theft device, because its lead sealing matter is soft, uses general tool can carry out demolition, and its dependability is low, and eliminates gradually.Existing improvement structure is: at screw after the counter sink on table door screws in and connects watchcase, adopts cylinder plastic packaging cap to be blocked in counter sink by screw, and maintainer is so that whether cylinder plastic packaging cap is destroyed, it is judged that whether user carries out enumerator surreptitiously changes.Owing to cylinder plastic packaging cap is simple, it can also lossless reinstall after dismounting, it is impossible to maintainer plays the effect of warning, equally exists the problem that dependability is low.
Summary of the invention
In order to overcome existing line to wear formula Antitheft lead seal and cylinder plastic packaging cap exists the deficiency that dependability is low, the antitheft Plastic packaging apparatus of the gas meter, flow meter that the present invention provides a kind of reasonable in design, dismounting can not be restored, dependability is high, applied widely.
The technical solution adopted for the present invention to solve the technical problems is: the antitheft Plastic packaging apparatus of a kind of gas meter, flow meter, it includes a fixture and a locked part, it is characterized in that: described fixture includes the fixation wall that a firm banking and is arranged on firm banking, the inner side of fixation wall is provided with a lock chamber, described firm banking has a fixing hole, be provided with some non-return sheets in the end of described fixation wall, described non-return sheet stretches into lock intracavity and the center to lock chamber is drawn in；Described locked part includes a capping and some latch hooks, is connected through locking bar respectively between latch hook with capping, and described latch hook stretches into lock chamber correspondence and is buckled on non-return sheet.
Described capping is encapsulated in the accent place in described lock chamber.
Described capping is encapsulated on the end face of described fixation wall.
The symmetrical profile of described latch hook is dihedral.
Described non-return sheet, the number of latch hook are six.
The fixture of the present invention includes the fixation wall that a firm banking and is arranged on firm banking, firm banking has a fixing hole, being provided with a lock chamber in the inner side of fixation wall, be provided with some non-return sheets in the end of fixation wall, non-return sheet stretches into lock intracavity and the center to lock chamber is drawn in；The locked part of the present invention includes a capping and some latch hooks, is connected through locking bar respectively between latch hook with capping, its reasonable in design；Latch hook stretches into lock chamber correspondence and is buckled on non-return sheet, gas meter, flow meter is overhauled or steals change time, only by destruction is removed the conventional dismounting that could realize gas meter, flow meter, dismounting can not be restored, dependability is high for it, applied widely.

Labelling in figure: 1. fixture, 101. firm bankings, 102. fixation wall, 103. lock chambeies, 104. non-return sheets, 105. fixing holes, 2. locked part, 201. cappings, 202. latch hooks, 203. locking bars.
Detailed description of the invention
In FIG, the antitheft Plastic packaging apparatus of a kind of gas meter, flow meter, it includes fixture 1 and a locked part 2.For ease of its destructiveness being removed when maintenance, fixture 1 and locked part 2 in the present embodiment all adopt the plastic material of routine to make.
In fig. 2, fixture 1 includes firm banking 101 and the fixation wall 102 being arranged on firm banking 101.In the present embodiment, this fixation wall 102 around arranging, forms a lock chamber 103 along firm banking 101 periphery in the inner side of fixation wall 102.
As in figure 2 it is shown, be provided with some non-return sheets 104 in the end of fixation wall 102, this non-return sheet 104 stretches in lock chamber 103, and draws in the center in lock chamber 103.
It should be noted that, can pass through respectively bonding forming, the conventional molding mode making such as one-body molded between firm banking 101 and fixation wall 102, fixation wall 102 and non-return sheet 104, consider plastic packaging requirement of strength and anufacturability, in the present embodiment, between firm banking 101 and fixation wall 102, fixation wall 102 and non-return sheet 104, the one-time formed mode of preferential employing realizes.
As in figure 2 it is shown, have a fixing hole 105 on firm banking 101.Fixing hole 105 is for the traverse of attachment screw, it is achieved with the connection of miscellaneous part.
In figure 3, locked part 2 includes a capping 201 and some latch hooks 202, is connected through locking bar 203 respectively between latch hook 202 with capping 201.Considering plastic packaging requirement of strength and anufacturability, in the present embodiment, between capping 201 and locking bar 203, locking bar 203 and latch hook 202, the one-time formed mode of preferential employing realizes.
For realizing encapsulation function, capping 201 both can be encapsulated in the accent place in lock chamber 103, it is also possible to is encapsulated on the end face of fixation wall 102.As it is shown in figure 1, in the present embodiment, capping 201 is encapsulated in the accent place in lock chamber 103.
For improving the reliability used, as in figure 2 it is shown, the symmetrical profile of latch hook 202 is dihedral.
For making plastic packaging strength uniform, in the present embodiment, the number of non-return sheet 104 is set to six, and it is around being distributed in fixation wall 102；The number of latch hook 202 is also set to six, and it surrounds through corresponding locking bar 203 respectively and is distributed in capping 201.
Fixture 1 in use, is placed in the counter sink of table door by the present invention, and attachment screw passes fixing hole 105 and fixture 1 and table door, watchcase fixed, and the latch hook 202 of locked part 2 stretches in lock chamber 103, is buckled on the non-return sheet 104 of fixture 1 by latch hook 202；Meanwhile, the inner side edged surface on latch hook 202 outwards launches under the push effect of screw head, it is prevented that latch hook 202 and non-return sheet 104 disengage.When gas meter, flow meter being overhauled or surreptitiously change, the conventional dismounting that only could realize gas meter, flow meter by the structure of the present invention carries out destruction remove, present invention dismounting can not be restored, its dependability height.
Because fixture 1 is an independent individuality, only need to being positioned in the counter sink of table door in use, attachment screw can pass the fixing hole 105 on fixture 1, is connected realizing screw between fixture 1, Biao Men and watchcase, therefore the present invention is applied widely.
