Just, take off card and press pre-buried line box of auricle formula

Technical Field

The utility model belongs to the technical field of electric power construction equipment, especially, relate to a just, take off card and press pre-buried line box of outer ear formula.

Background

The wire passing box is used for conveniently constructing and intensively arranging the separated wires at a specific position. When the pipeline is embedded in a building, sometimes the line box needs to be added because of too long distance. Generally, if the length of the pipeline exceeds 15 meters, a wire passing box is added to facilitate threading, the electrical property is not provided, and the inlet wire and the outlet wire are the same or the same turn of wire.

Most of the pre-buried wire passing boxes in the current construction are crosswise bound at four corners of a box body of the wire passing box by binding wires 12 as shown in figures 1 and 2 and then fixed by iron nails 11, or are directly fixed by using lengthened large-size nails 13 penetrating through the box, wherein the binding wires are needed for the former, 4 iron nails are respectively used for fixing 4 corners, and the work and the material are relatively wasted; the latter iron nail needs to pass through the wire passing box body, and the iron nail needs to be pulled out manually after the mould is removed, so that the wire passing box body is damaged, the quality of the box body is influenced, and the damaged box body can damage the wire skin during threading.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a just, take off card and press pre-buried line box of crossing of outer ear formula, it can effectively improve pre-buried loaded down with trivial details process of crossing the line box fixed in the electric power construction, reduces construction cost comprehensively, improves work efficiency, can not cause the damage to the box body during the later stage drawing of patterns, influences the box body quality.

In order to achieve the above object, the utility model provides a just, take off card and press pre-buried line box of crossing of outer ear formula, including crossing line box body, its characterized in that: the lateral surface of crossing the relative both sides of line box body is provided with fixed iron sheet respectively, and fixed iron sheet setting is crossing the edge that line box body is close to opening one side, and fixed iron sheet and cross the horizontal limit that the joint has L type external ear between the line box body, is provided with the fixed orifices that is used for will crossing the line box and fix on fixed die plate that supplies iron nail or self tapping screw to pass on the perpendicular limit of L type external ear.

Furthermore, the central position of fixed iron sheet is provided with the round hole, and the horizontal limit of L type auricle corresponds the round hole position and is provided with the arch that can block and establish in the round hole.

Furthermore, the part of the L-shaped outer ear transverse edge clamped in the fixed iron sheet extends to the outer side of the fixed iron sheet, and the end part of the L-shaped outer ear transverse edge is tilted upwards.

Furthermore, the inner side surfaces of the two opposite sides of the wire passing box body are provided with inner lugs used for being connected with the cover of the wire passing box body, and the inner lugs are arranged at the edge of the wire passing box body close to one side of the opening.

The easy-to-release outer-lug-type embedded wire passing box is characterized in that: the L-shaped outer ear and the L-shaped inner ear are respectively arranged on different side surfaces of the wire passing box body.

Furthermore, the fixed iron sheet is welded on the wire passing box body, and a gap is reserved between the fixed iron sheet and the wire passing box body for clamping and connecting the L-shaped external ear

The utility model discloses a just, take off the design of joint pressure formula, because the power of tearing open the mould down during the drawing of patterns, and the template dynamics of weighing down is great, can just take off L type external ear area template and directly demolish outward. And the fixing hole is formed in the outer ear, so that the installation is convenient, and the working time is reduced. And there is the upwarp at the afterbody of external ear, strengthens L type external ear and crosses the fixed strength of line box body, guarantees not receive the exogenic action and make and cross line box skew preset position when concreting.
