Description

The slide mechanism of withdrawing device

The utility model relates to a kind of slide mechanism of withdrawing device, is to the improvement of existing withdrawing device slide mechanism, is particularly suitable for using on withdrawable circuit breaker.

Mainly there is following defective in the drawer of existing circuit breaker: at first, because guide plate is in pull-out location latch-up-free mechanism, thereby make the state of pulling out of drawout chassis smudgy; Secondly, guide plate is also latch-up-free mechanism in the separation point position, make that the locking of drawout chassis in the separation point position is not very reliable, thereby prestige is being assisted the safe in utilization of switch; Once more, also latch-up-free mechanism between two guide plates, thereby when drawout chassis is outwards pulled out, the circuit breaker on the drawout chassis can not be spun off fully between pair of side plates, thus bring inconvenience for the maintenance and the inspection of mechanism.

The purpose of this utility model is to provide a kind of guide plate of can realizing easily in the locking of pull-out location, separation point position and the mutual locking between two guide plates, and can make withdrawable circuit breaker break away from side plate fully in the pull-out location so that the slide mechanism of the withdrawing device of maintenance and inspection.

The purpose of this utility model is achieved like this, a kind of slide mechanism of withdrawing device, it comprises the upper and lower guide rail 2,3 that is located on the side plate 1 and is located at the guide plate 5 of 2,3 on upper and lower guide rail and is located at guide plate 6 on the guide plate 5, the below, rear end of described guide plate 5 has additional down lockplate 11, and following lockplate 11 tools keep off pin 12 and can rotate around little axle 13; The front end top of described guide plate 6 has additional button 24 respectively, goes up lockplate 18, button 24 tools are pressed pin 27, crotch 25 and can be rotated around little axle 26, the both sides of last lockplate 18 are distinguished tool shift fork 20, spike 28 and can be rotated around little axle 16, and a spring 22 is connected between button 24 and the last lockplate 18; Have additional guide plate clamping block 34 on the described side plate 1, guide plate clamping block 34 tool lock hooks 32.

The utility model is owing to have additional locking mechanism respectively on guide plate 5,6 and side plate 1, thereby can realize easily that guide plate is in the locking of pull-out location, separation point position and the mutual locking between two guide plates, simultaneously can make withdrawable circuit breaker break away from side plate fully in the pull-out location, thereby offer convenience for keeping in repair with inspection.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is a structure diagram of the present utility model.

Side plate 1 of the present utility model has a pair of, described slide mechanism on the inboard of each side plate 1 is provided with a cover respectively symmetrically.The upper and lower guide rail 2,3 of slide mechanism on side plate 1, is equipped with guide plate 5 by screw slidably between upper and lower guide rail 2,3, guide plate 5 is supporting by upper and lower slide block 4,14.Guide plate 6 is slidably mounted on the guide plate 5, and by groove 31 sliding engaged on fulcrum post mounted thereto 30 and the guide plate 5, and the groove 9 that is positioned at guide plate 6 front ends is sliding engaged with the fulcrum post 8 that is installed in guide plate 5 front ends.

Button 24 of the present utility model is installed on the front end top, axis hole 21 of guide plate 6 by little axle 26, and can be around little axle 26 revolutions, be respectively arranged with on button 24 and press pin 27, crotch 25, crotch 25 sides offer spring fixed hole, are connected with an end of spring 22 in the hole.The lockplate 18 of going up of the present utility model is installed in the front end top of guide plate 6, a side of button 24 by little axle 16, and can be around little axle 16 revolutions, at the both sides of last lockplate 18 difference tool shift fork 20, spike 28, middle tool projection 17, the other end of spring 22 is connected on the lockplate 18.Spring 22 of the present utility model is positioned at the spring groove 23 of guide plate 6, under the effect of spring 22, makes button 24 be subjected to anticlockwise commentaries on classics distance, is subjected to clockwise torque and go up lockplate 18.Spike 28 on last lockplate 18 touches the stop hook 29 of guide plate 5 front ends, and on the button 24 to press pin 27 spacing by 19 on the retaining pin on the guide plate 6, shift fork 20 on the last lockplate 18 is pressed 27 on pin when spacing on the button 24, realizes the mutual locking between guide plate 5 and the guide plate 6.Its releasing process can be realized by two kinds of operations, a kind of is by by the button on the bottom guide 6 24, make button 24 depress the shift fork 20 of lockplate 18 around little axle 26 rotations, allow lockplate 18 make the spike 28 of the other end break away from the stop hook 29 of guide plates 5 front ends and release around 16 rotations of little axle, this moment, guide plate 6 relative guide plates 5 travelled forward, and guide plate 5 still keeps transfixion; Another kind is when breaker body is put into drawout chassis, directly depresses the projection 17 of upper end in the middle of the lockplate 18 by breaker body, and lockplate 18 is rotated around little axle 16, and presses the button 24 and reaches same release effect.

Lockplate 11 down of the present utility model is installed in the below, rear end of guide plate 5 by little axle 13, and can be around little axle 13 rotations, at the lower end of following lockplate 11 tool retaining pin 12, touch the front end of lower guideway 3 when retaining pin 12, and the front end of following lockplate 11 is by 7 on the guide plate pin of guide plate 6 rear ends belows when clamped, can realize the locking of guide rail 5 and lower guideway 3.Its releasing process is by moving inward guide plate 6, makes the angle 10 of guide plate 6 belows boost down the front end of lockplate 11, allows down lockplate 11 take out the rotation of 13 clockwise directions around for a short time, makes guide plate 5 releases thereby force retaining pin 12 to break away from 8 cooperating of front end of lower guideway.

Along with the release between the release between above-mentioned guide plate 6 and the guide plate 5 and guide plate 5 and the lower guideway 3, make the crotch 25 of the button 24 that is positioned on the guide plate 6 cross the groove 15 of guide plate 5 front ends and under the tension of spring 22, catch on the groove 15 of guide plate 5, realized the mutual locking of guide plate 5 with guide plate 6, this moment, guide plate 5 can only inwardly advance with guide plate 6 under thrust.

Guide plate clamping block 34 of the present utility model is fixed on the outside of side plate 1 by hold-down screw 33, the lock hook 32 that bends inwards at the lower end of guide plate clamping block 34 tool one, when breaker body arrives the separation point position, crotch 25 on the button 24 is crossed the guide plate clamping block 34 on the side plate 1, and by 32 lockings of the lock hook on the guide plate clamping block 34, guide plate 5 can only move forward and can not be drawn out with guide plate 6 this moment, thereby had realized the locking of separation point position.When wanting release, have only by pressing the button 24, make the lock hook 32 of the crotch 25 parts disengaging guide plate clamping block 34 on the button 24, this moment, guide plate 5 just can be drawn out with guide plate 6.
