Abstract
The utility model discloses a threaded rod supporting structure for motor junction box, wherein the junction box comprises a square box body whose rear wall is provided with a wire outlet hole and a cylinder which is fixedly connected on the wire outlet hole outside the rear wall of the box body, the outer end of the cylinder is fixedly connected on the installing surface of a motor stand, a mounting seat is arranged on the lower portion of the wire outlet hole outside the rear wall of the box body, a plurality of mounting holes are evenly distributed on the mounting seat, the installing surface of the motor stand is provided with screwed holes corresponding to the mounting holes on the mounting seat, and a threaded rod is inserted in the mounting holes on the mounting seat and the screwedholes on the installing surface of the motor stand, which enables the mounting seat to be connected with the motor stand. As the threaded rod is connected between the rear wall of the junction box and the motor stand, combining the connection between the cylinder on the rear wall of the box body and the motor stand, the threaded rod supporting structure enables the junction box to be stably installed on the motor stand, and thoroughly eliminates the phenomena that the junction box sags because of infirm installing, and the motor shakes during operating.
Description
Technical field
The utility model relates to the accessory structure on a kind of motor, particularly a kind of screw rod supporting construction that is used for connection box for motor.
Background technology
Generally all attach main electrical scheme box and auxiliary connection box on the motor, be provided with an instrument transformer and some binding posts in the main electrical scheme box.The auxiliary connection box is mainly used in the connection of the lead-in wire and the heater cable of temperature element on the motor.Existing a kind of terminal box is all offered installing hole on a sidewall, and directly is fixed on the electric machine stand by screw bolt and nut, therefore the terminal box of this structure be fixed on the electric machine stand also more firm.Yet the structure that also has terminal box in a kind of motor at present is the cylinder of the about 200mm of an also fixedly connected length on the outer surface of its sidewall wire hole position, and the about 600mm of the length of terminal box itself, terminal box is to fixedly connected with electric machine stand by the mounting panel of this cylinder outer end.Because the instrument transformer of certain weight is installed in the terminal box, equal the principle of arm of force * gravity according to moment, therefore this fixed form can cause terminal box to sink, and in the motor shake that also can cause terminal box in service, makes the installation of terminal box have unsafe hidden danger.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of screw rod supporting construction that is used for connection box for motor to be provided, and it is firm that it can make terminal box be installed in more to stablize on the electric machine stand.
The technical scheme that realizes above-mentioned purpose is: a kind of screw rod supporting construction that is used for connection box for motor, described terminal box comprises that square box body and that a rear wall is provided with wire hole is fixedly connected on the cylinder at the outer wire hole place of box body rear wall, the outer end of described cylinder is fixedly connected on the installed surface of electric machine stand, the below of the wire hole that described box body rear wall is outer is provided with a mount pad, uniformly on this mount pad offer some installing holes, installing hole on the described electric machine stand installed surface on the corresponding mount pad is offered screwed hole, be interspersed with screw rod in the screwed hole on installing hole on the described mount pad and the electric machine stand installed surface, so that mount pad is connected with electric machine stand.
The above-mentioned screw rod supporting construction that is used for connection box for motor, wherein, two of described screw rod is provided with thread segment, and interlude is six prisms and the length length less than described cylinder.
The above-mentioned screw rod supporting construction that is used for connection box for motor, wherein, described mount pad is an angle steel, it is fixed on the outer gusset of box body rear wall and horizontally set.
Adopted the technical scheme that is used for the screw rod supporting construction of connection box for motor of the present utility model, promptly between terminal box rear wall and electric machine stand, connect a screw rod, being connected in conjunction with the cylinder on the box body rear wall and electric machine stand again, terminal box 1 firmly is installed on the electric machine stand, thoroughly eliminated terminal box in the prior art and installed not firm and produce sagging and in the phenomenon of motor generation shake in service.

Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 to Fig. 4, the cantilevered support structure that is used for connection box for motor of the present utility model, comprise terminal box 1, mount pad 2, electric machine stand 3 and screw rod 4, wherein, terminal box 1 comprises that a square box body 11 and is fixedly connected on the outer cylinder 12 of box body 11 sidewalls, offer wire hole 110 on the rear wall of box body 11, cylinder 12 is fixedly connected on outer wire hole 110 places of box body 11 rear walls, the outer end of cylinder 12 is provided with mounting panel 120, offers installing hole on this mounting panel 120 and is connected by screw on the installed surface of electric machine stand 3;
Installing hole 20 on the installed surface of electric machine stand 3 on the corresponding mount pad 2 is offered three screwed holes 30;
Two of screw rod 4 is provided with thread segment, and interlude is six prisms and the length length less than cylinder 12; Screw rod 4 has three, they intert respectively in the installing hole 20 and the screwed hole 30 on electric machine stand 3 installed surfaces corresponding with it on mount pad 2, by 40 nuts that are fitted on the mount pad 2 that each screw rod 4 is fixing respectively again, so that mount pad 2 is connected with electric machine stand 3.
Six prisms of screw rod 4 interludes can make the distance between installation personnel manual adjustments terminal box 1 and the electric machine stand 3.
The screw rod supporting construction that is used for connection box for motor of the present utility model, between terminal box 1 rear wall and electric machine stand 3, connect a screw rod 4, being connected in conjunction with the cylinder 12 on box body 11 rear walls and electric machine stand 3 again, terminal box 1 firmly is installed on the electric machine stand, thoroughly eliminated terminal box 1 in the prior art and installed not firm and produce sagging and in the phenomenon of motor generation shake in service.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
