This kind of reading class instrument counting mechanism prevents dismouting and puts through with the locking lever fork in the through-hole on the inside boss of main part, inside main part was arranged in to locking lever and tapered end, did not need complicated upper cover and major structure, through the ram to the inside punching press of rivet round pin, rivet round pin bottom warp directly seals upper cover and main part, through rivet round pin and locking lever, the dual tear-open effect of preventing of tapered end realizes preventing tearing open the function of counting mechanism.
Description
Technical field
This utility model relates to a kind of antiwithdrawal device, is specially a kind of reading class instrument counting mechanism antiwithdrawal device, belongs to tamper technical field.
Background technology
In measuring Instrument technology field, prevent technology stolen, each enterprise takes some measures and is applied in essential core technical pattern, such as reading class instrument counting mechanism, in prior art, some reading class manufacturers are for preventing unauthorized user from it illegally being dismounted, frequently with first by lead sealing line through the hole on special screw nut and the hole of indwelling or ring on shell, it is inserted in the hole of lead with holes, then the method clamping lead with lead sealing pliers, this lead sealing complex operation, the structure of shell is limited relatively larger, and product is unsightly, or adopt fluting, the method that barb is set, as long as but this method somewhat applies pulling force and will destroy barb, do not have the effect of tamper at all.
For solving the problems referred to above, therefore it is proposed that a kind of reading class instrument counting mechanism antiwithdrawal device.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of reading class instrument counting mechanism antiwithdrawal device, through rivet pin and locking bar, the dual tamper effect of tapered end, it is achieved the tamper function of counting mechanism.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one reading class instrument counting mechanism antiwithdrawal device, including upper cover and main body, described cover rim is alignd with main body coupling and is connected, described cover rim is provided with counter sink, it is provided with rivet pin in described counter sink, described body rim is provided with punching, described punch center line intersects vertical with counter sink centrage, described main body inner wall top is provided with boss, described main body boss is provided with through hole, described upper cover lower surface is provided with locking bar, described locking bar lower end is provided with tapered end, described tapered end is made up of snap close, gap is had between described snap close and tapered end axis, described snap close upper end is provided with ramp structure, described length of locking rod is identical with main body inner wall convex platform thickness.
Further, described upper cover inner wall surface is concordant with body interior boss surface.
Further, described snap close beveled ends protrudes from locking bar cylindrical.
nullThis utility model reaches to provide the benefit that: by being inserted by locking bar in the through hole on body interior boss，Snap close is squeezed，Compress to the gap between snap close and tapered end axis，When upper cover lower surface is placed on boss lower surface with body lower surface laminating rear catch，Snap close releases extruding，Restore to the original state，Locking bar and tapered end are placed in body interior，Need not complicated upper cover and agent structure，And do not affect the outward appearance of entirety，Install easy and simple to handle，Only need to firmly press，Rivet pin is installed in the counter sink at upper cover outer rim place，The bottom of rivet pin is positioned at punching，By jumper bar to the inside punching press of rivet pin，Upper cover and main body are directly shut by the deformation of rivet pin bottom，Both can guarantee that the intensity of upper cover and main body connected，Further tamper effect can be played again，Through rivet pin and locking bar、The dual tamper effect of tapered end，Realize the tamper function of counting mechanism.
