Fig. 1 is the structural representation of the utility model for the screw of low-voltage distribution cabinet.
Fig. 2 is the plan view of nut in the utility model.
Fig. 3 is the structural representation of screw rod in the utility model.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the screw that the utility model is used for low-voltage distribution cabinet comprises the nut 1 and screw rod 2 that are fixed together, nut 1 comprises cap body 11, first groove 12, second groove 13, first projection 14, second projection 15, first groove 12 is positioned at lower half portion of cap body 11, second groove 13 is positioned at the side of upper half part of cap body 11, first protruding 14 fixes with the top of cap body 11, and the second projection 15 is fixed in the first projection 14; Screw rod 2 comprises the body of rod 21, the 3rd groove 22, outside thread 23, plastic sheath 24, lug, nib 25, most advanced and sophisticated 26,3rd groove 22 is positioned at the upper part of the body of rod 21, outside thread 23 is positioned at the upper part of the body of rod 21 and is positioned at the below of the 3rd groove 22, plastic sheath 24 is enclosed within the lower part of the body of rod 21, lug, nib 25 is positioned at the lower part of the body of rod 21 and is positioned at the below of plastic sheath 24, and most advanced and sophisticated 26 are positioned on the bottom of the body of rod 21.
Be provided with internal thread 151 in second projection 15, be so conveniently connected with other element flights, increase fixed performance.
The shape of the first projection 14 is cuboid, can conveniently engage with spanner like this, can conveniently drive cap body 11 to rotate together.
The shape of the second projection 15 is cylindrical body, saves volume and material like this, reduces costs.
Working principle of the present utility model is as follows: the first groove, the second groove can facilitate lemon to move cap body.3rd groove strengthens the fixed performance between nut and screw rod, prevents from coming off.Outside thread is connected with outside element flights, plastic sheath can increase frictional behaviour, the convenient engaging of lug, nib, most advanced and sophisticated convenient insertion, the utility model is fixed with other elements by outside thread, plastic sheath, lug, nib, tip etc., and nut is provided with the second groove in addition, so not easily rolls, thus not easily lose, ensure that shrouding is installed fastening.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
