Abstract
The invention discloses a contact connection and disconnection control device of a low voltage drawer type switch cabinet drawer. In the working process, a transmission shaft and a transmission sleeve rotate at the same time or the transmission sleeve rotates independently, so that a primary contact and a secondary contact are connected or disconnected together when the working position and the separation position of a drawer are switched, the secondary contact is connected or disconnected independently when the experiment position and the separation position are switched, a few parts are provided, operation is easy, and no noise is generated when connection and disconnection are carried out; meanwhile, the components are made of recyclable materials, products can be recycled after being scraped, and solid waste polluting environment is avoided.
Description
Technical field
The present invention relates to a kind of drawer of drawer-type low voltage switchgear Contact Breaking/Making Operations control device in low-voltage complete switch equipment and control appliance, belong to Low Voltage Electrical Apparatus.
Background technology
Drawer of low-voltage switch cabinet in the market realizes once, the connection of secondary moving contact or separation, and need to drive whole drawer body to move, operating process is wasted time and energy, and mechanism is easy to wear, causes system unstable.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of structure simple, laborsaving, the low pressure drawer-type switch cabinet Contact Breaking/Making Operations control device that anti-error performance is good, when not moving drawer body, directly realization once, deciliter action of secondary moving contact.
The technical scheme solving the employing of its technical problem is: design a kind of low pressure drawer-type switch cabinet Contact Breaking/Making Operations control device, comprise gear box, one-time contact push pedal, secondary contact push pedal, drive sleeve, power transmission shaft; Gear box is made up of gear box cover, gear block, roller gear, bevel gear, and bevel gear, roller gear and bearing are horizontally installed on same square bar in gear box, and roller gear engages with one-time contact push pedal tooth bar.Another bevel gear and bearing are longitudinally installed with power transmission shaft in gear box, two bevel gears engage each other, secondary contact push pedal has internal tooth list structure, drive sleeve is sleeved on power transmission shaft, drive sleeve is designed with the various shape holes such as window, groove, boss, and has cover shoulder to engage with secondary contact push pedal tooth bar.Gear box cover becomes casing with gear block fixed Combination, and restriction roller gear, bevel gear can only make axial rotation motion.
To operate key to insert drive sleeve vertical axial and rotate, the tooth bar in secondary contact push pedal and the gears meshing in drive sleeve, secondary contact push pedal is moved in the horizontal direction under the turning effort of drive sleeve, thus control secondary contact deciliter; Operation key has multi-functional operation guide vane end stop, power transmission shaft vertical axial under the effect that can operate key rotates, under gear box effect, become roller gear horizontal axis rotate, one-time contact push pedal moves in the vertical direction under the turning effort of roller gear, thus control one-time contact deciliter; Power transmission shaft is coaxial in drive sleeve, must rotate when power transmission shaft rotates together with drive sleeve; Drive sleeve can rotate separately under operation key effect, so just achieves drawer work when separation point position switches together with one secondary contact deciliter, independent deciliter of secondary contact when experiment and separation point position switch.
Operation key has fusiformis hand handle, hand being designed to Openworks shape, fusiformis hand more meeting palm body line feature, more convenient operation, laborsaving and safety, Openworks shape structure can alleviate key weight, saves material simultaneously, reduces costs; Power transmission shaft input gear case vertical axial rotate, export into roller gear horizontal axis rotate, one-time contact push pedal moves in the vertical direction under the turning effort of roller gear, thus control one-time contact deciliter; Drive sleeve gear engages with secondary contact push pedal tooth bar, and secondary contact push pedal is moved in the horizontal direction under the turning effort of drive sleeve, thus control secondary contact deciliter.
Low pressure drawer-type switch cabinet Contact Breaking/Making Operations control device of the present invention, operationally power transmission shaft and drive sleeve are rotated simultaneously, or drive sleeve rotates separately, so just, achieve drawer work when separation point position switches together with one secondary contact deciliter, independent deciliter of secondary contact when experiment and separation point position switch, mechanism element quantity is few, and easily, when performing deciliter action, noiselessness produces in operation; And parts adopt recyclable material to make, and can reuse, can not produce the solid waste of contaminated environment after product rejection.

Below in conjunction with accompanying drawing, the present invention is further described.
In figure: 1, operate key 2, drawer body 3, gear box cover 4, secondary contact push pedal 5, drive sleeve 6, power transmission shaft 7, one-time contact push pedal 8, roller gear 9, bevel gear 10, gear block
Embodiment
As shown in the figure, drawer of drawer-type low voltage switchgear Contact Breaking/Making Operations control device of the present invention, comprise gear box cover 3, gear block 10, roller gear 8, bevel gear 9, one-time contact push pedal 7, secondary contact push pedal 4, drive sleeve 5, power transmission shaft 6, bevel gear 9, roller gear 8 and bearing are horizontally installed on same square bar in gear box, and roller gear 8 engages with one-time contact push pedal 7 tooth bar.Another bevel gear 9 and bearing are longitudinally installed with power transmission shaft 6 in gear box, two bevel gears 9 engage each other, secondary contact push pedal (4) has internal tooth list structure, drive sleeve (5) is sleeved on power transmission shaft (6), drive sleeve (5) is designed with the various shape holes such as window, groove, boss, and has cover shoulder to engage with secondary contact push pedal (4) tooth bar; Gear box cover 3 becomes casing with gear block 10 fixed Combination, and restriction roller gear 8, bevel gear 9 can only make axial rotation motion.
Operation key 1 is inserted drive sleeve 5 vertical axial to rotate, the gears meshing in the tooth bar in secondary contact push pedal 4 and drive sleeve 5, secondary contact push pedal 4 is moved in the horizontal direction under the turning effort of drive sleeve 5, thus control secondary contact deciliter; Operation key 1 has multi-functional operation guide vane end stop, power transmission shaft 6 vertical axial under the effect that can operate key 1 rotates, under gear box effect, become roller gear 8 horizontal axis rotate, one-time contact push pedal 7 moves in the vertical direction under the turning effort of roller gear 8, thus control one-time contact deciliter; Power transmission shaft 6 is coaxial in drive sleeve 5, must rotate when power transmission shaft 6 rotates together with drive sleeve 5; Drive sleeve 5 can rotate separately under operation key 1 acts on, and so just achieves drawer work when separation point position switches together with one secondary contact deciliter, independent deciliter of secondary contact when experiment and separation point position switch.Operation key 1 has fusiformis hand handle, and hand is being designed to Openworks shape, and fusiformis hand is more meeting palm body line feature, more convenient operation, and laborsaving and safety, Openworks shape structure can alleviate key weight, saves material simultaneously, reduces costs.
