Abstract
The invention discloses a reading instrument counting mechanism anti-dismounting device which comprises an upper cover and a main body, wherein a counter bore is formed in the edge of the upper cover, a rivet pin is arranged in the counter bore, a punched hole is formed in the edge of the main body, a boss is arranged on the upper portion of the inner wall of the main body, a through hole is formed in the boss of the main body, a lock rod is arranged on the lower surface of the upper cover, a lock head is arranged at the lower end of the lock rod and consists of a lock catch, a gap is formed between the lock catch and a lock head center shaft, an inclined surface structure is arranged at the upper end of the lock catch, and the. 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
The present invention relates to a kind of anti-dismantling device, it is specially a kind of reading class instrument and counts mechanism's tamper device, belong to tamper technical field.
Background technology
In surveying instrument technical field, preventing techniques is stolen, each enterprise takes some measures and is applied in essential core technology structure, such as reading class instrument counting mechanism, in prior art, some reading class manufacturers are for preventing unauthorized user from it illegally being dismounted, lead sealing line is first passed hole or the ring of the hole on special screw nut and indwelling on shell by normal employing, insert in the hole of band hole lead again, then the method for lead is pressed with lead sealing clamp, this kind of lead sealing operation is loaded down with trivial details, the structural limitations of shell is bigger, and product is unsightly, or adopt fluting, the method of barb is set, as long as but this kind of method applies pulling force a little will destroy barb, do not have the effect of tamper at all.
For solving the problem, therefore we propose a kind of reading class instrument counting mechanism tamper device.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that a kind of reading class instrument counts mechanism's tamper device, through rivet pin and locking bar, and the dual tamper effect of tapered end, it is achieved the tamper function of counting mechanism.
In order to solve the problems of the technologies described above, the present invention provides following technical scheme:
A kind of reading class instrument of the present invention counts mechanism's tamper device, comprise upper cover and main body, described cover rim is alignd with main body coupling and is connected, described cover rim is provided with heavy head bore, it is provided with rivet pin in described heavy head bore, described body rim is provided with punching, described punching medullary ray is crossing vertical with heavy head bore medullary ray, 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, the described lower end of locking bar 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 lock hook beveled ends is given prominence to and locking bar cylindrical.
The useful effect that the present invention reaches is: by being inserted by locking bar in the through hole on body interior boss, lock hook is squeezed, to the gap compression between lock hook and tapered end axis, lock hook when upper cover lower surface and body lower surface after fitting and it is placed on boss lower surface, lock hook releases extruding, recover original state, locking bar and tapered end are placed in body interior, do not need complicated upper cover and agent structure, and do not affect overall outward appearance, install easy and simple to handle, only need to firmly press, rivet pin is installed in the heavy head bore 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 distortion of rivet pin bottom, can ensure that the intensity of upper cover and main body connects, 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.
