Abstract
The utility model discloses a kind of stable type screw component, including：One fixed plate；Two feed screw nuts, are arranged on fixed plate bottom, the central shaft of the two threaded hole is misaligned parallel；Two screws, extend through two feed screw nuts；One bar shaped rail, is set, its upper surface is serrated along two screw length directions；One card resistance mechanism, in fixed plate, can opposing fixed plate slide up and down, the card resistance actuator base be in and the matched zigzag in bar shaped rail upper surface.The utility model realizes stability lifting of the screw component in static state by the jigsaw fit of can slide up and down in card resistance mechanism frame-type frame and the bar shaped rail of its bottom.
Description
Technical field
Screw technical field is the utility model is related to, more particularly to a kind of stable type screw component.
Background technology
Existing screw component, is by the thread fitting between screw and feed screw nut, realizes screw and feed screw nut
Relative motion.But the flight pitch of existing screw and the flight pitch of feed screw nut, it is interference fitted, makes due to existing
The two in opposing stationary state, feed screw nut can also be produced with screw it is small rock, therefore, the prior art, which exists, to be lacked
Fall into, it is necessary to further improve.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of stable type screw component.
To achieve the above object, the concrete technical scheme of the utility model is as follows：A kind of stable type screw component, including：
One fixed plate；
Two feed screw nuts, are arranged on fixed plate bottom, the central shaft of the two threaded hole is misaligned parallel；
Two screws, extend through two feed screw nuts；
One bar shaped rail, is set, its upper surface is serrated along two screw length directions；
One card resistance mechanism, in fixed plate, can opposing fixed plate slide up and down, the card resistance actuator base is in and bar shaped
The matched zigzag in rail upper surface.
It is preferred that the card resistance mechanism includes：Frame-type frame that bottom is serrated, some compression springs, arranged on frame-type frame
Two chute holes of two side, the spacing knob for being respectively arranged on two chute hole tops, the fixed plate runs through frame-type frame, described some
Compression spring is arranged between fixed plate upper surface and the inner surface on frame-type frame top along frame-type frame length direction；The fixed plate is led to
The chute hole and spacing knob for crossing both sides are flexibly connected with frame-type frame.
It is preferred that two feed screw nut's minute surfaces are symmetrically set in fixed plate bottom, card resistance mechanism and bar shaped rail are arranged on two screw spiral shells
Between mother.
Using above-mentioned technical proposal, the utility model passes through frame-type frame and its bottom of can slide up and down in card resistance mechanism
The jigsaw fit of bar shaped rail, realizes stability lifting of the screw component in static state.
Brief description of the drawings
Fig. 1 is the top view of the utility model；
Fig. 2 is the explosive view of the utility model；
Fig. 3 is the cooperation figure of the utility model center type frame and fixed plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Referring to figs. 1 to shown in Fig. 2, the utility model provides a kind of stable type screw component, including：
One fixed plate 1；
Two feed screw nuts 2, are arranged on 1 bottom of fixed plate, the central shaft of the two threaded hole is misaligned parallel；
Two screws 3, extend through two feed screw nuts 2；
One bar shaped rail 4, is set, its upper surface is serrated along two screws, 3 length direction；
One card resistance mechanism 5, in fixed plate 1, can opposing fixed plate 1 slide up and down, 5 bottom of card resistance mechanism be in
The matched zigzag in 4 upper surface of bar shaped rail.
Wherein, the card resistance mechanism 5 includes：Frame-type frame 51 that bottom is serrated, some compression springs 52, arranged on frame-type
Two chute holes 53 of 51 two side of frame, the spacing knob 54 for being respectively arranged on two chute holes, 53 top, the fixed plate 1 run through frame-type
Frame 51, some compression springs 52 are arranged in 1 upper surface of fixed plate and 51 top of frame-type frame along 51 length direction of frame-type frame
Between surface；The fixed plate 1 is flexibly connected by the chute hole 53 and spacing knob 54 of both sides with frame-type frame 51.
Two feed screw nuts, 2 minute surface is symmetrically set in 1 bottom of fixed plate, and card resistance mechanism 5 and bar shaped rail 4 are arranged on two feed screw nuts 2
Between.
The operation principle of the utility model：
When fixed plate 1 is moved with respect to screw 3, the frame-type frame 51 in card resistance mechanism 5 is in separated shape with bar shaped rail 4
State, at this time, frame-type frame 51 is under the action of compression spring 52 so that the low side of its chute hole 53 is connected with fixed plate 1.
It is inconsistent by press-frame type frame 51 to its bottom and bar shaped rail 4 when fixed plate 1 is static with respect to screw 3, adjust at this time
The spacing knob 54 of 51 both sides of frame-type frame so that fixed plate 1 is relatively fixed to 53 top of chute hole or top, in this way, according to this
The matched jigsaw fit of kind, realizes stabilization inactive state of the fixed plate 1 with respect to two screws 3, is not in because of screw 3 and screw spiral shell
What the interference fit of mother 2 produced rocks.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
Under every utility model in the utility model is conceived, equivalent structure made based on the specification and figures of the utility model
Conversion, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
