Abstract
The utility model discloses a T-shaped bolt, comprising a rectangular head and a screw, the T-shaped bolt is characterized in that, a fastening end surface of the rectangular head is provided with a rotary limiting step, the contour sideline of the rotary limiting step is provided with two tip parts, the two tip parts are disposed in the opposite angle directions of the fastening end surface, and the screw is connected on the rotary limiting step. The T-shaped bolt is used for installation of an external electrical appliance element of a high-voltage electric appliance box, and makes installation more convenient, firmer, and more reliable.
Description
Technical field
The utility model relates to a kind of connection fastening piece, is specifically related to a kind of improvement invention of T-shaped bolt.
Background technique
Installing of the external electrical apparatus element of High-Voltage Electrical Appliances case, generally at first will be laid on the aluminium alloy extrusions whole piece of T-shaped groove the shell of High-Voltage Electrical Appliances case, then in T-shaped groove, put square nut, the bottom of square nut is provided with spring, when electrical apparatus element are installed, mounting hole is aimed at the screw of square nut, the screw and screw to realize the installation of electrical apparatus element then screwed on.The greatest drawback that above-mentioned installation process exists is: the one, and mounting hole is not very convenient with aiming at of screw, the 2nd, the spring of square nut bottom easily lacks, in case spring disappearance or damage, square nut just can not effective location in T-shaped groove, make mounting hole more difficult with aiming at of screw, the 3rd, the above-mentioned mode that is connected and fixed itself just is not desirable especially.
Summary of the invention
The purpose of this utility model is intended to provide a kind of installation for the external electrical apparatus element of High-Voltage Electrical Appliances case, make install more convenient, firmly reach reliable T-shaped bolt.
The utility model is implemented by following technical solution:
A kind of T-shaped bolt, comprise rectangular head and screw rod, it is characterized in that: the fastening end face of rectangular head is provided with the rotary spacing step, and the profile sideline of rotary spacing step has two tips, two tips arrange the angular direction fastening end face, and described screw rod is connected on the rotary spacing step.
The T-shaped bolt that the utility model provides, its crucial innovative point is that the fastening end face of rectangular head is provided with the rotary spacing step, when with the rectangular head of T-shaped bolt along T-shaped groove setting party after put in the groove from the top of T-shaped groove, the profile sideline of rotary spacing step can be over against the notch of T-shaped groove, because the profile sideline of rotary spacing step has two tips, so after clockwise 90 degree rotate T-shaped bolt, two tips can be run into two trough rims of notch respectively, so T-shaped bolt can not clockwise rotate again.When electrical apparatus element are installed, as long as being aimed at the screw rod that packs into T-shaped bolt, mounting hole then screws on nut, when the dextrorotation jack panel, T-shaped bolt can not produce and clockwise rotate, and can make the installation of electrical apparatus element more convenient behind the said employing T-shaped bolt of the present utility model, firmly reach reliably.
As preferably, the profile sideline of rotary spacing step has diamond shape, and two tips in profile sideline are two acute angle summits of rhombus.The fastening end mask has rectangular shape, and two acute angle summits of rhombus are positioned on the long limit of rectangle, and two acute angle summits are symmetrical in the central axis of T-shaped bolt.Two parallel hypotenuses of rhombus and the minor face of rectangle have the angle of 13-15 degree.

The utility model has following accompanying drawing:
Fig. 1 is stereogram of the present utility model,
Fig. 2 is the side-looking directional diagram of Fig. 1,
Fig. 3 is the directional diagram of looking up of Fig. 1,
Fig. 4 is that the utility model begins to put in the T-shaped groove,
Fig. 5 is after the utility model is put T-shaped groove and 90 degree rotations into,
Fig. 6 is the side view of Fig. 5.
Embodiment
Such as Fig. 1, shown in 2 and 3, T-shaped bolt of the present utility model, comprise rectangular 1 and screw rod 3, rectangular 1 fastening end face 1a is provided with rotary spacing step 2, the profile sideline of rotary spacing step 2 has two tip 2a, two tip 2a arrange the angular direction fastening end face 1a's, described screw rod 3 is connected on the rotary spacing step 2, the profile sideline of rotary spacing step 2 has diamond shape, the two tip 2a in profile sideline are two acute angle summits of rhombus, fastening end face 1a has rectangular shape, two acute angle summits of rhombus are positioned on the long limit of rectangle, two acute angle summits are symmetrical in the central axis of T-shaped bolt, and two parallel hypotenuses of rhombus and the minor face of rectangle have the angle a of 13-15 degree.
Shown in Figure 4, with the rectangular head of T-shaped bolt along T-shaped groove setting party to putting in the groove from the top of T-shaped groove; Fig. 5 and shown in Figure 6, after T-shaped bolt was put T-shaped groove and clockwise 90 degree rotations into, two tips of rotary spacing step can be run into the up and down trough rim of T-shaped groove notch respectively, so T-shaped bolt can not clockwise rotate again, this moment, the rectangular head slip of T-shaped bolt was located in the T-shaped groove, and screw rod exposes.When electrical apparatus element are installed, as long as being aimed at the screw rod that packs into T-shaped bolt, the mounting hole of electrical apparatus element then screws on nut, and when the dextrorotation jack panel, T-shaped bolt can not produce and clockwise rotate, and the easy for installation, firm of electrical apparatus element reaches reliably.
