Abstract
The utility model discloses an anti-explosion knob. The anti-explosion knob comprises a handle, an anti-explosion spindle, a flame-proof housing, and an ejection pin. The anti-explosion spindle is arranged in the flame-proof housing in a pass-through manner. The upper end of the handle is a holding rotary end, and the lower end of the handle has an annular structure. The upper end of the anti-explosion spindle is provided with a boss which is in insertion and connection with the lower end of the handle. The lower end of the anti-explosion spindle and the ejection pin are in linkage through an adjusting spindle and an adjusting ratchet wheel. The adjusting ratchet wheel is sleeved onto the lower end of the adjusting spindle. The outer circumferential surface of the adjusting spindle is provided with ratchets which are in engaged rotation with the adjusting ratchet wheel. The lower end surface of the anti-explosion spindle is provided with an insertion and connection slot for the upper end of the adjusting spindle to insert. The lower end of the adjusting spindle is provided with a contact surface which can be pressed against the ejection pin, and the contact surface has a rolling shape. By adopting the structure, the utility model provides an anti-explosion knob having advantages of simple structure, small size and good overall anti-explosion effect.
Description
Technical field
The utility model relates to a kind of explosion-proof knob head.
Background technology
Explosion-proof knob head can be converted to swing offset straight-line displacement for promoting button mandril action.But at present, the most complex structure of existing explosion-proof knob head, bulky, and integrated explosion proof system effect is also poor.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, volume is little and integrated explosion proof system is respond well explosion-proof knob head.
For achieving the above object, the utility model provides a kind of explosion-proof knob head, comprise handle, explosion-proof rotating shaft, flameproof enclosure, push rod, described explosion-proof rotating shaft is arranged in flameproof enclosure, end is rotated for gripping in the upper end of described handle, the lower end of described handle is structure ringwise, the upper end of described explosion-proof rotating shaft is provided with the boss plugging with described handle, at its lower end, between the lower end of described explosion-proof rotating shaft and push rod, pass through to regulate rotating shaft and regulate ratchet gearing, described adjusting ratchet sleeve is loaded on the lower end that regulates rotating shaft, and on the outer circumference surface of described adjusting rotating shaft, be provided with the ratchet that is meshed with described adjusting ratchet and rotates, the lower surface of described explosion-proof rotating shaft offers the inserting groove inserting for described adjusting rotating shaft upper end, the lower end of described adjusting rotating shaft is provided with the surface of contact that can connect with described push rod, and described surface of contact is the shape that just rises and falls.
The beneficial effects of the utility model are: adopt said structure, due between the upper end of described explosion-proof rotating shaft and handle, for pegging graft, coordinate, and between the lower end of described explosion-proof rotating shaft and push rod, pass through to regulate rotating shaft and regulate ratchet gearing, therefore make that one-piece construction is simple, overall volume is less, and integrated explosion proof system is respond well.
The utility model can further be set to also be provided with between described handle and flameproof enclosure O-ring seal.Adopt said structure, the water-proof function that has that O-ring seal can make described explosion-proof knob head is set.
The utility model also can further be set to also be provided with location jump ring between described explosion-proof rotating shaft and flameproof enclosure, between described adjusting ratchet and flameproof enclosure, is also provided with spring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Provided as shown in Figure 1 a kind of explosion-proof knob head, comprise handle 1, explosion-proof rotating shaft 2, flameproof enclosure 3, push rod 4, described explosion-proof rotating shaft 2 is arranged in flameproof enclosure 3, end is rotated for gripping in the upper end 11 of described handle 1, the lower end 12 of described handle 1 is structure ringwise, the upper end of described explosion-proof rotating shaft 2 is provided with the boss 21 plugging with described handle, at its lower end 12, between the lower end of described explosion-proof rotating shaft 2 and push rod 4, by adjusting rotating shaft 5 and adjusting ratchet 6, link, described adjusting ratchet 6 is set in the lower end that regulates rotating shaft 5, and on the outer circumference surface of described adjusting rotating shaft 5, be provided with the ratchet 51 that is meshed with described adjusting ratchet 6 and rotates, the lower surface of described explosion-proof rotating shaft 2 offers the inserting groove 22 inserting for described adjusting rotating shaft 5 upper ends, the lower end of described adjusting rotating shaft 5 is provided with the surface of contact 52 that can connect with described push rod 4, and described surface of contact 52 is the shape that just rises and falls.Between described handle 1 and flameproof enclosure 3, be also provided with O-ring seal 7.Between described explosion-proof rotating shaft 2 and flameproof enclosure 3, be also provided with location jump ring 8, between described adjusting ratchet 6 and flameproof enclosure 3, be also provided with spring 9.
During use, people's gripping handle 1 rotates, thereby drive explosion-proof rotating shaft 2 and regulate rotating shaft 5 rotations, the surface of contact 52 connecting due to described adjusting rotating shaft 5 and push rod 4 is the shape that just rises and falls, therefore can drive described push rod 4 oscilaltions, realize the action that promotes button mandril, and coordinate for pegging graft due between the upper end of described explosion-proof rotating shaft 2 and handle 1, and by adjusting rotating shaft 5 and adjusting ratchet 6, link between the lower end of described explosion-proof rotating shaft 2 and push rod 4, therefore make that one-piece construction is simple, overall volume is less, and integrated explosion proof system is respond well.
