Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

1 is a perspective view showing the appearance of the terminal box fixture according to the present invention, Figure 2 is a view showing a state of use of the terminal box fixture according to the present invention.

Prior to describing the present invention, the terminal box to which the fixture according to the present invention is applied will be briefly described.

The terminal box 100 is installed to be embedded in the reinforced concrete wall in a state in which the opening of the receiving space in which the terminals are installed is exposed to the outside. The terminal box has a terminal box body 102 having a substantially rectangular front surface which forms the accommodating space for installing a terminal, and the terminal box body 102 can receive various wires for connection to the terminal. A plurality of wire inlets 106 and additionally closed inlets 106 are further formed to be openable to install additional inlets 106 as needed.

In addition, the front cover of the terminal box body 102 is integrally coupled to the cover frame 104 to provide a place for installing the cover.

On both sides of the terminal box body 102 having the above configuration, the fixture 108 constituting the core of the present invention to support the terminal box body 102 to be movable relative to the reinforcing frame is installed.

First, the fastener 108 is molded to form a rectangular shape with a plastic injection molded article, and one side is fitted with a guide rail 112a extending from the terminal box body 102 to the cover frame 104. The support groove 112b is formed in a shape corresponding to the guide rail 112a so as to be supported, and the body portion 114a in which the fixing groove 113 is formed so that the reinforcing bar can be inserted and fixed to the opposite side thereof. It includes.

In addition, at the center of one surface of the body portion 114a, that is, the inner wall forming the support groove 112b forms the groove 118 so that the coil spring 110 can be inserted and supported. A predetermined support protrusion (not shown) is integrally formed at the vertical end of the groove 118.

One end of the coil spring 110 is inserted into the groove 118 while being supported to be supported by the support protrusion, and the other end thereof is caught by a separate fastening piece 120 to be fixed to the cover frame 104. do.
