Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that say that the specific embodiment of description is used only for explaining the present invention herein, and
It is not used in the restriction present invention.
Embodiment 1:
As shown in Figs 1-4, a kind of limiter, including spool 1 is crossed, the both ends open of spool 1 is crossed, is crossed in spool 1 circumferentially
If there are two unidirectional non-return mechanism 2, the unidirectional non-return mechanism 2 include the inclined ramp 21 for being fixed on 1 inner wall of spool, with incline
Inclined ramp 21 cooperates the sliding block 22 being slidably connected, the crimping 23 that 22 back side of sliding block is arranged in and is solidified as a whole with sliding block 22, consolidates
It is scheduled on 21 both ends of inclined ramp and baffle 24 for being limited to 22 sliding scale of sliding block and for supporting sliding block 22
Compressed spring 25, the inclined ramp 21 are tilted along the axial setting and one end for crossing spool 1 towards the axle center for crossing spool 1, from
And the inclined ramp 21 of each unidirectional non-return mechanism 2 is made to cooperatively form a cone space, the sliding block 22 of each unidirectional non-return mechanism 2 can
Space of lines undergauge excessively or expanding along the sliding of 21 synchronous reciprocating of corresponding tilt slideway to make corresponding crimping 23 cooperatively form,
One end of the spring is supported on sliding block 22, and the other end is supported on the baffle 24 at expanding end.
In use, as shown in Figure 4,5, cable 3 is passed through from crossing in space of lines for spool 1 is crossed, spool 1 is crossed when cable 3 is opposite
When mobile towards the undergauge end (the smaller one end of the cone space cooperatively formed towards each inclined ramp 21) for crossing spool 1,
Spring, which supports sliding block 22, contacts its crimping 23 with cable 3, then cable 3 with movable slider 22 along inclined ramp 21 towards contracting
Diameter end is moved, and the space of lines excessively that the corresponding crimping 23 of each sliding block 22 cooperatively forms becomes smaller and prevents it from continuing until blocking cable 3 out
It is mobile, spool 1 is crossed towards the expanding end (taper cooperatively formed towards each inclined ramp 21 for crossing spool 1 when cable 3 is opposite
The bigger one end in space) it is mobile when, cable 3 is moved along inclined ramp 21 towards expanding end with movable slider 22, each sliding block 22
The space of lines of crossing that crimping 23 cooperatively forms is corresponded to become larger that cable 3 is enable smoothly to continue to move to.Limiter of the present invention, benefit
Multiple unidirectional non-return mechanisms 2 of 1 inner circumferential of spool setting are crossed with edge, thus realize that cable 3 can only be moved unidirectionally relative to spool 1 is crossed,
And then realize limiter with respect to the purpose that cable 3 limits.
The spool 1 of crossing is opposite structure, including two and half 11, two described half 11 side is mutually cut with scissors
It connects, another side is detachably connected by buckle structure 12, and a unidirectional non-return machine is respectively equipped on each half 11
Structure 2.Crossing spool 1 is opposite structure, and side is hinged, and the other side is detachably connected, so that this be enable to cross 1 side of spool
Just it covers on cable 3.
The inclined ramp 21 includes two tilt slides 211 being oppositely arranged, and is additionally provided at least on each tilt slide 211
One sliding slot 2111, the two sides of the sliding block 22 are respectively equipped with the raised line 221 of cooperation sliding slot 2111, the two sides difference of sliding block 22
Embedded be slidably connected is carried out with two tilt slides 211.The design keeps the cooperation of inclined ramp 21 and sliding block 22 stronger.
The crimping 23 is opening towards the concave arc shape structure for crossing 1 axle center of spool, and crimping 23 is equipped with several
Towards the inclined non-return tooth 231 in expanding end.Non-return tooth 231 is set on crimping 23, further improves the unidirectional of limiter
Non-return effect.
It is described cross spool 1 one end be equipped with connection structure 13, can for screw connection structure 13, buckle connecting structure 13 or
Person's bayonet lock connection structure 13, so as to be connected to the electric power work for covering on cable and opposite cable being needed to be limited or positioned
On tool, connected electric power tool is limited or positioned.
