As shown in fig. 1 to 5, the terminal block device of the present invention includes a fixing strip 3 and a terminal block 1 disposed on the fixing strip 3.

When the fixing strip 3 is used, the fixing strip is fixed at a preset position on a steel bar in a wall body, and the specific position can be determined according to the design position of the junction box. Through fixing the fixed strip 3 on the reinforcing bar, guarantee the rigidity of fixed strip 3, likewise, the position of the terminal box 1 of fixing on fixed strip 3 is also fixed firmly.

Be formed with a plurality of holes 4 on fixed strip 3, hole 4 is used for fixed terminal box 1, and 4 inner walls in hole are equipped with the first arch 5 of a plurality of slopes, are provided with pole setting 2 on terminal box 1, are provided with the protruding 6 of second of a plurality of slopes in pole setting 2 periphery, and the protruding 6 orientation of second is opposite with first arch 5, inserts back in hole 4 when pole setting 2, and the mutual block of first protruding 5 of second makes terminal box 1's fixed more firm.

Specifically, the upright stanchion 2 can also be a bolt bar, one end of the bolt bar is fixedly arranged on the junction box 1, the other end of the bolt bar penetrates through the hole 4, the other end of the bolt bar is fixed in a rotating manner through a nut, and the junction box can be fixed.

Further, as shown in fig. 3 and 5, the first projection 5 and the second projection 6 have a right-angled trapezoidal cross-sectional shape. When the junction box is used, the upright rod 2 is inserted into the hole 4, the inclined edges of the first protrusion 5 and the second protrusion 6 are abutted to each other, and the first protrusion 5 and the second protrusion 6 have forces which are mutually restricted in two directions, so that the junction box 1 and the upright rod 2 form a tight connection structure. In detail, in the process that the vertical rod 2 is inserted into the hole 4, a thrust is given to the vertical rod 2, so that the first protrusions 5 on the vertical rod 2 move into the hole 4, meanwhile, the protruding inclined plane structure design arranged in the vertical rod 2 and the hole 4 enables the inserting process of the vertical rod 2 to be more convenient, and the stress between the first protrusions 5 and the second protrusions 6 is mutually restricted, so that the outward movement of the vertical rod 2 is not facilitated, and the vertical rod 2 and the fixing strip 3 are firmly connected.

Further, the vertical rod 2 keeps a preset distance from the edge of the junction box 1, and the upright column 2 is arranged in the fixing strip 3, so that a certain distance needs to be reserved at the edge of the vertical rod 2 close to the junction box 1, the fixing strip 3 is guaranteed not to exceed the edge of the front face of the junction box 1, the junction box 1 is attractive after being fixed, the overall effect of the wall face is not affected, and specific data of the preset distance are determined according to the position of the vertical rod 2 on the junction box 1 and the distance from the hole 4 of the fixing strip 3 to the edge of the fixing strip 3 in the width direction.

Furthermore, terminal box 1 is the cube structure, and the positive border department at perpendicular terminal box is set up to pole setting 2 symmetry, and, the quantity of pole setting 2 is four at least, and one end is two, fixes terminal box 1. Of course, the junction box 1 may also be circular, or prismatic, or other shapes, and the vertical rods 2 are symmetrically disposed on the top and bottom surfaces of the junction box 1, and in this case, the requirement for the preset distance is not limited. And, the quantity of pole setting 2 is four at least, guarantees the stability of terminal box 1 connection.

Further, fixed strip 3 is the elasticity fixed strip, and is detailed, and fixed strip 3 can be hard rubber or PVC material, makes pole setting 2 can plant in fixed strip 3 to fix through the flange of restricting each other, convenient operation connects stably.

Further, the one end of fixed strip 3 is provided with the third arch 7 of a plurality of slopes, is provided with the recess at the other end of fixed strip 3, is equipped with the fourth arch 8 of a plurality of slopes in the recess, and the orientation of third arch 7 and fourth arch 8 is opposite, and when the end to end of two fixed strips 3, the mutual block of third arch 7 and fourth arch 8 realizes the extension of the length direction of fixed strip 3, realizes more fixed of terminal box 1.

Further, the height of the third protrusion 7 and the height of the fourth protrusion 8 are at least 5mm, which ensures a firm connection between the fixing strips 3.

Furthermore, the holes 4 are uniformly distributed on the fixing strip 3, so that the row junction boxes are uniform in space and attractive.

The junction box device of the present invention will be further described with reference to a more specific embodiment.

A terminal block device includes a rectangular terminal block 1 and a fixing strip 3. All set up two pole settings 2 at the top surface and the bottom surface of terminal box 1, two pole settings 2 set up in the border department that is close to the left and right sides, and the diameter of pole setting 2 is 10mm, length is 15mm, and pole setting 2 is 10mm apart from the distance on box limit, and wherein, the first arch 5 of the row of ally oneself with that sets up on pole setting 2 is right trapezoid, and right trapezoid's long limit is 2mm, the minor face is 0.5mm, highly is 1mm.

The interval of a plurality of holes 4 on the fixed strip 3 is 30mm, and the diameter of hole 4 is 10mm the same with the diameter of pole setting 2, and second arch 6 on the lateral wall of hole 4 also is right trapezoid, but second arch 6 in the hole 4 and first arch 5 on the pole setting 2 are each other for 180 symmetry, and the long limit of right trapezoid on the hole 4 is 2mm, the minor face is 0.5mm, highly is 1mm.

Before the wiring box is used, the fixing strips 3 are fixedly connected to the steel bars of the wall body, and the distance between the upper fixing strip 3 and the lower fixing strip 3 is determined according to the size of the wiring box 1. Then, the posts of the terminal box 1 are inserted into the holes 4 of the fixing strip 3, and the fixing of the terminal box device is completed.

The fixing of the junction box 1 is firm, the junction box 1 needs to be fixed through a steel bar in the prior art, steel is saved, and the operation is more convenient. Particularly, in the arrangement of the row of junction boxes, the junction boxes 1 are uniformly spaced, and all the junction boxes 1 are positioned on the same horizontal line.
