Abstract

The utility model discloses a plastic-shelled lock seal, which comprises a plastic shell and an insert inserted in the plastic shell. A plastic body wraps a spring chip with an elastic barb so as to form the insert, a step for clamping the elastic barb is arranged on the inner wall of the plastic shell, after being inserted into the plastic shell, the insert cannot be drawn out rearwards due to blockage of the step, a threading groove is arranged at the front end of the plastic shell, a plug for plugging the threading groove is disposed at the rear end of the plastic body, a clamp groove for holding a seal line is arranged on the spring chip, when in sealing, the preassembled plastic-shelled lock seal is placed at a seal position of an electrical metering facility, then the seal line threads through a seal hole of the electrical metering facility by threading equipment, then the seal line is pressed in the clamp groove of the spring chip by a manipulator, and finally, the insert is pressed into the plastic shell by a press so as to complete sealing of the electrical metering facility, thereby realizing automation during sealing.

Description

It is a kind of that to mould shell locked

Technical field

The utility model relates to a kind of the locked of electric metering facility that be used to seal, and it is locked that particularly a kind of self-locking disposable that is used on the electrical metering facility automatic gauging streamline is moulded shell, to realize automatically sealing up operation.

Background technology

In the locked field of electrical metering facility, it is better that disposable self-locking is moulded the locked antifalse effect than original lead sealing seal of shell at present, thereby obtain to use widely; But because self-locking is moulded the operation that the locked seal of shell need manually be worn Sealed wire usually, development along with society, the use of electrical metering device is also more and more, the work of measurement verification department of power supply administration is also more and more heavier, and traditional craft is sealed up and is operated on the efficient and all can't satisfy existing work requirements on the personnel, so part power supply administration is in order to raise the efficiency, the equipment that need to adopt full-automatic calibrating and seal up automatically, then develop a kind of conveniently be used for sealing up automatically operation mould the locked research schedule of having put on people of shell.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of be convenient to automatically to seal up operation disposable, and to mould shell locked.

The technical scheme that its technical matters that solves the utility model adopts is:

It is a kind of that to mould shell locked, comprise plastic casing and insert the plug-in unit of plastic casing inside, described plug-in unit is to be wrapped in by plastic body to be with the spring chip of elasticity hangnail to constitute, described plastic casing inwall has the step that the elasticity hangnail is blocked, be subjected to the obstruction of step after plug-in unit inserts and can't extract backward, described plastic casing front end has Wire channel in building, and described plastic body rear end is provided with the obstruction of shutoff Wire channel in building, and described spring chip is provided with the draw-in groove of ccontaining Sealed wire;

As further improvement in the technical proposal, described plastic casing is divided into main body and cover plate two parts, and main body is provided with mounting groove, and cover plate is provided with the pin that is inserted in the mounting groove, and the fabrication hole sealing of the described pin in back with the main body tail end is installed.

The beneficial effects of the utility model are: when sealing up, as long as adopt will install in advance mould the locked seal position that is placed on the electrical metering facility of shell, adopt threading device Sealed wire to be passed the seal hole of electrical metering facility then, then use mechanical arm Sealed wire to be pressed in the draw-in groove of spring chip, by press-loading device plug-in unit is pressed in the plastic casing at last and just can finishes sealing up of electric power metering device, thereby realize sealing up the robotization in the process, because the obstruction that adds on the plastic body of being honored as a queen just is pressed together on Sealed wire on the Wire channel in building of plastic casing, has effectively realized the product self-locking, anti-purpose of opening.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, it is a kind of that to mould shell locked, comprise plastic casing 1 and insert the plug-in unit 2 of plastic casing 1 inside, described plug-in unit 2 is to be wrapped in spring chip 22 by plastic body 21 to constitute, respectively there is an elasticity hangnail 221 spring chip 22 both sides, and be one upwards, one downwards, make and to consider its directivity when plug-in unit 2 inserts, plastic casing 1 inwall has the front and

back stages step

14,15 that elasticity hangnail 221 is blocked, be subjected to the obstruction of step after plug-in unit 2 inserts and can't extract backward, described prime step 14 is slightly higher than back level steps 15; Prime step 14 makes plug-in unit 2, plastic casing 1 structure that is assembled into one in advance, during use as long as the elasticity hangnail 221 of plug-in unit 2 is pushed to the back level step 15 of plastic casing inwall; In addition, described plastic casing 1 is divided into main body 12 and cover plate 13 two parts, main body 12 is provided with mounting groove 121, cover plate 13 is provided with the pin 131 that is inserted in the mounting groove 121, after making cover plate 13 be installed in main body 12, reach better sealing effectiveness, can coat sealing glue or use ultrasonic soldering at joint, fabrication hole 122 sealings of the described pin 131 in back with main body 12 tail ends are installed, thereby prevented that the lawless person from opening plug-in unit 2 from the fabrication hole 122 of plastic casing 1 afterbody, thereby improved the security of products energy greatly.

This product has Wire channel in building 11 at plastic casing 1 front end, and described plastic body 21 rear ends are provided with the obstruction 211 of shutoff Wire channel in building, and described spring chip 22 is provided with the draw-in groove 222 of ccontaining Sealed wire 5.When sealing up, as long as adopt will install in advance mould the locked seal position that is placed on the electrical metering facility of shell, adopt threading device Sealed wire 5 to be passed the seal hole of electrical metering facility then, then use mechanical arm Sealed wire 5 to be pressed in the draw-in groove 222 of spring chip 22, by press-loading device plug-in unit 2 is pressed in the plastic casing 1 at last and just can finishes sealing up of electric power metering device, thereby realize sealing up the robotization in the process, because the obstruction 211 that adds on the plastic body 21 of being honored as a queen just is pressed together on Sealed wire 5 on the Wire channel in building 11 of plastic casing 1, has effectively realized the product self-locking, anti-purpose of opening.

In addition, main body 12 of this product and cover plate 13 use transparent plastic to make, whether thereby making people can more clearly understand locked inside is destroyed, in addition, between main body 12 and cover plate 13, be provided with antifalsification label 4 or RFID electronic tag, this design makes antifalsification label 4 or RFID electronic tag avoid extraneous destruction, be printed on the bar code or the two-dimension code of unique asset number on the described antifalsification label 4, antifalsification label 4 both can play anti-fake effect to product, play the information stores effect again, can make things convenient for each user being carried out computer management by locked electrical metering facility.
