Abstract
The utility model discloses an electricity meter box capable of preventing wires from being pulled and drawn, and is to provide the electricity meter box capable of preventing the wires from being pulled and drawn which is capable of preventing the wires from being scratched and damaged in the wire installing process. The main points of the technical scheme are that when the wires are inserted into the electricity meter box, operation personnel insert the wires into an installation column directly; a lock sleeve moves to a metal sleeve under the conflict of a sealing gasket; the bottom surface of the metal sleeve is abutted against the conical surface of the lock sleeve to enable the lock sleeve to be stressed to the axle center direction, thereby driving a clamping ring to lock the wires, preventing the wires from galloping or even being pulled away from the electricity meter box due to the pulling of the wires outwardly, and preventing the wires from being scratched and damaged due to friction; only by pressing a disengaging ring, the bottom of the disengaging ring enables claw teeth of a clamping ring to stretch outwardly, thereby enabling the wires to be separated from the locking of the clamping ring; and the wires can be detached directly by pulling. Therefore, the structure can effectively prevent the wires from being pulled away from the wire concentration groove easily, is convenient for the operation personnel to wire and install, and is beneficial to reduce the installation difficulty of the operation personnel.
Description
Technical field
The utility model relates to a kind of ammeter box, and more particularly, it relates to a kind of anti-electric wire pull ammeter box.
Background technology
In national grid; ammeter is modal a kind of metering outfit; the user's of Zhe basic unit application is more general; every household is used an ammeter to I haven't seen you for ages; therefore for avoid the ammeter of installing to be without subject to extraneous wind and weather or even stealing throughout the year, ammeter need to be arranged in ammeter box for the protection of ammeter.Conventionally the side of ammeter box is provided with for electric wire being penetrated to ammeter box or from the through hole of the electric wire of moving out in ammeter box, need to be by the diameter processing of through hole when electric wire being penetrated or move out ammeter box larger, make through hole enough electric wires that can penetrate or move out.And after ammeter box is installed; in the wiring installation process of electric wire, often can pull electric wire; to such an extent as to can make electric wire produce play or even be pulled out out ammeter box; therefore electric wire can produce in through hole friction; because ammeter box is formed by the sheet material system of enclosing; therefore the inner ring of its through hole is comparatively sharp, easily makes electric wire produce scratch when friction and damages.Simultaneously also because electric wire is easily pulled out out ammeter box, and the wiring that will be not easy to operating personnel is installed, and has increased operating personnel's installation difficulty.

Embodiment
Referring to figs. 1 through Fig. 3, the anti-electric wire pull of the utility model ammeter box embodiment is described further.
A kind of anti-electric wire pull ammeter box, comprise casing 1 and chamber door 2, the madial wall of described casing 1 convexes with for the erection column 4 through electric wire 3, described erection column 4 inside are provided with stepped hole 41, described stepped hole 41 is provided with sealing gasket 42, described erection column 4 inside are also provided with the snap ring 43 for securing electric lines 3, depart from ring 44, metallic sheath 45 and columnar lock sleeve 46, described metallic sheath 45 is fixedly connected on the inwall of erection column 4, conflict and be connected with sealing gasket 42 in described lock sleeve 46 one end, the sidewall of described lock sleeve 46 is provided with for forming the spacing conical surface coordinating 461 with metallic sheath 45, the described conical surface 461 is conflicted and is connected with the bottom surface of metallic sheath 45, described disengaging ring 44 is arranged in snap ring 43, described snap ring 43 is nested in lock sleeve 46 inwalls.When electric wire 3 need to penetrate from ammeter box outside, operating personnel directly insert electric wire 3 in erection column 4, lock sleeve 46 moves to metallic sheath 45 directions under the conflict of sealing gasket 42, the conical surface 461 of the bottom surface conflict lock sleeve 46 of metallic sheath 45 makes stressed towards axis direction of lock sleeve 46, thereby drive snap ring 43 locking electric wires 3, therefore in the wiring installation process of electric wire 3, can avoid making electric wire 3 produce play or even be pulled out out ammeter box because pullling laterally electric wire 3, therefore can avoid electric wire 3 to damage because friction produces scratch; When will more rewiring 3 time, only need press and depart from ring 44, the bottom that departs from ring 44 just can outwards strut the blade tooth of snap ring 43, makes electric wire 3 depart from the locking of snap rings 43, directly extracts just detachable electric wire 3.Therefore this structure can effectively be avoided the easily situation from being pulled out out in hub slot of electric wire 3, and handled easily personnel's wiring is installed, and is conducive to reduce operating personnel's installation difficulty.
Described snap ring 43 comprises the ring body portion 431 being wholely set and the blade tooth portion 432 consisting of some blade tooths 4321, described ring body portion 431 is cylindrical shape, described blade tooth 4321 all, towards the 431 axis direction settings of ring body portion, is provided with blade tooth portion breach 4322 between adjacent blade tooth 4321.Blade tooth portion breach 4322 on snap ring 43 facilitates blade tooth 4321 to arrange towards the axle center of ring body portion 431, is convenient to be departed from ring 44 and struts, and makes snap ring 43 have larger coupling mechanism force; Snap ring 43 is made as to cylindrical shape, guarantees that snap ring 43 can firmly be arranged on erection column 4 inside.
Described ring body portion 431 consists of some solid sheet 4311, between adjacent solid sheet 4311, be provided with ring body portion breach 4312, described ring body portion breach 4312 quantity are identical with blade tooth 4321 quantity, described blade tooth portion breach 4322 quantity are identical with solid sheet 4311 quantity, described ring body portion breach 4312 extends to blade tooth portion 432, and described blade tooth portion breach 4322 extends to ring body portion 431.In ring body portion 431, be provided with ring body portion breach 4312, using ring body portion 431 also as locking the application of force a part, blade tooth portion breach 4322 on blade tooth 4321 extends to ring body portion 431 simultaneously, ring body portion breach 4312 in ring body portion 431 extends to blade tooth 4321, make snap ring 43 there is the elastic force towards axle center, strengthened the coupling mechanism force of snap ring 43, also made blade tooth 4321 more easily be departed from ring 44 and strut.
Described ring body portion's breach 4312 and blade tooth portion breach 4322 intervals arrange.Coupling mechanism force and the elastic force of snap ring 43 are evenly distributed, and coupling mechanism force is larger, has avoided causing electric wire 3 by blade tooth 4321 crimps because of discontinuity.
Described snap ring 43 forms (it should be noted that, described metal material can be copper product) herein by good springiness, on-deformable metal material.Utilize metal material good springiness, on-deformable feature, after making blade tooth portion 432 repeatedly be strutted, lock by electric wire 3, can also keep higher coupling mechanism force, and be difficult for rupturing, damaging, the mission life-span is long.
