Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses an insertion type device for a circuit breaker, as shown in fig. 1-4, comprising a base 1, wherein a plurality of mounting grooves 18 are formed inside the base 1, mounting holes 11 are formed on mounting surfaces of the base 1 and the circuit breaker, the mounting holes 11 are provided with internal threads, the mounting holes 11 are in threaded fit connection with fastening screws 12, the base 1 is further provided with a rotating rod 13, the rotating rod 13 extends into the mounting grooves 18, a driving helical gear 14 positioned in the mounting groove 18 is fixedly connected to the rotating rod 13, a rotating shaft 122 is arranged in the mounting groove 18, a driven helical gear 121 engaged with the driving helical gear 14 is arranged on the rotating shaft 122, so that when the driving helical gear 14 rotates, the driven helical gear 121 and the rotating shaft 122 are driven to rotate together, two rectangular splines 123 are fixedly connected to the rotating shaft 122, and the spline grooves 151 in a sleeve 15 are in a strip shape and are matched with the splines 123, as shown in fig. 3, the size of the spline groove 151 in the vertical direction is larger than that of the spline 123, the spline 123 can move up and down in the spline groove 151, and the sleeve 15 and the fastening screw 12 are fixedly connected.
Based on the above arrangement, when the user installs the breaker, the installation fixing hole of the breaker is aligned with the installation hole 11 in advance, then, the rotating rod 14 is rotated, as shown in fig. 2, the rotating rod 14 drives the driving bevel gear 14 to rotate, the driving bevel gear 14 is engaged to drive the driven bevel gear 121 to rotate, so that the rotating shaft 122 rotates together with the spline 123, under the engagement of the spline 123 with the spline groove 151, the sleeve 15 and the fastening screw 12 rotate together with the spline 123, and because the mounting hole 11 is matched with the fastening screw 12 by the thread, the fastening screw 12 extends out of the mounting hole 11 upwards and enters into the fixed mounting hole of the circuit breaker under the rotation to realize the fixed connection between the mounting hole 11 and the fastening screw, since the user can make a plurality of fastening screws 12 enter the fixed mounting holes of the circuit breaker only by rotating the rotating rod 14, the operation is very quick, and the mounting efficiency of the circuit breaker is greatly improved.
It should be noted that, when the sleeve 15 and the fastening screw 12 rotate and extend out of the mounting hole 11, the spline 123 moves in the spline groove 151 to a side relatively far away from the mounting hole 11, and the limiting block 152 is arranged outside the sleeve 15, so that when the spline 123 is about to be separated from the spline groove 151, the limiting block 152 abuts against the internal thread of the mounting hole 11, the sleeve 15 is limited to continue to move and extend out of the mounting hole 11, and therefore the spline groove 151 and the spline 123 cannot be separated from each other, and normal operation of the device is ensured.
As shown in fig. 1, a knob 16 is assembled at one end of the rotating rod 13 extending out of the base 1, a protective shell 17 is hinged on the base 1, the protective shell 15 covers the knob 16, so that the user is prevented from touching the knob 16 by mistake, and when the user wants to rotate the knob 16, the protective shell 15 is opened to operate the knob 16 therein.
As shown in fig. 2, an end face bearing 125 is further disposed in the mounting groove 18, the rotating shaft 122 abuts against the end face bearing 125, and the end face bearing 125 reduces friction between the rotating shaft 122 and the base 1 when rotating, so that the rotating rod 13 can rotate more easily and smoothly.
The utility model discloses a dwang 13 drive fastening screw 12 stretches out or returns mounting hole 11, when circuit breaker and base 1 carry out fixed mounting, only need align the fixed mounting hole of circuit breaker with mounting hole 11 on the base 1, rotatory dwang 13 can realize fixed mounting between the two, the user need not to screw up the screw one by one and fixes both, and when dismantling the circuit breaker, the separation between the two can be realized to the rotatory dwang 13 of reverse direction, the dismouting efficiency when maintaining the circuit breaker is improved; especially when the plug-in device is installed on the lateral wall of cubical switchboard or wall, it is more inconvenient that the user twists or screws out the screw, the utility model discloses the user's that has significantly reduced work load has reduced the time of operation maintenance.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
