Description
Technical field
The invention belongs to pet fixture fields, relate generally to a kind of pet tractor.
Background technology
Pet tractor is mainly used for the tractive of pet, pet tractor commercially available at present mainly comprises two kinds, one is simple, length immutable rope class tractor, and another has a rope dish, and can realize drag rope by this rope dish and controllably stretch.Because rope length can not change in front a kind of mode, have impact on the degree of freedom of pet action, the pet tractor of what thus people more and more adopted now is this controllable extensible, thus the pets such as cat and dog can be drawn easily.
Although the pet tractor of the controllable extensible that currently available technology exists is different profile, its base control mode is all identical or similar.As depicted in figs. 1 and 2, be provided with one with the wire spool 2 of ratchet 1, drag rope is around on wire spool 2.The bottom of locking sliding block 3 and ratchet 1 are interfered in FIG, and realize the control to ratchet 1 by cam bit 4 and the spring be arranged in locking sliding block 3.Under normal condition, locking sliding block 3 does not contact with ratchet 1, and wire spool 2 can freely rotate, and when needs control flexible, press cam bit 4, thus locking sliding block 3 is moved downward and blocks with ratchet 1, thus wire spool 2 is locked, rope lengths is immutable.The pet tractor of the controllable extensible is in fig. 2 similar to the structure in Fig. 1, is also the interacting state being controlled locking mechanism 7 and ratchet 1 by a controlling organization 5 and returning spring 6.Under normal condition, locking mechanism 7 does not contact with ratchet 1, and wire spool 2 can freely rotate, when needs control flexible, press controlling organization 5, make locking mechanism 7 and ratchet 1 interfere thus limit the rotation of wire spool 2, rope lengths is immutable, after force removes, under the effect of returning spring 6, locking mechanism 7 is upspring, and is returned to original state, and wire spool 2 can freely rotate.
This creates the terminal two problems, first problem is due under force-free state, and rope can free-extension, and thus once pet shakes off neck cover, then rope is regained fast, easily injure in this withdrawal process people or pet.
Second Problem is, because current structural design makes the contact of locking sliding block, locking mechanism and ratchet unreasonable, easily damages, loses efficacy.
Summary of the invention
For the defect existed in current pet tractor, we disclose a kind of new pet tractor, comprise housing, the wire spool with ratchet be installed in housing, gauge tap, latch segment and return spring, described latch segment is a lever construction, its rotating fulcrum is fixed on housing, lever two ends are respectively card and hold and control end, wherein blocking and holding is formed with towards the card of ratchet and projection, return spring is fixed between the card of latch segment and end and housing, the control end of latch segment and gauge tap are interfered, and pressing place of gauge tap exposes to housing.
Under normal condition, gauge tap is under the effect of return spring, and due to lever principle, card and the end of latch segment are depressed by return spring, and control end tilts, and card and projection are interfered with ratchet, and wire spool is in locking state, and rope can not free-extension.
When needs cord retraction, gauge tap is pressed downwards, thus make the control end of latch segment downward, due to lever principle, card and end tilt, and card and projection are lifted, depart from interference state with ratchet, wire spool can freely rotate, thus under the tractive of external force rope free-extension.Under this state, return spring is compressed generation deformation, and after pressing force removes, return spring impels card and projection to be again returned to interference state with ratchet by restoring force.
Preferably, case inside is also provided with a draw-in groove, and gauge tap can slide along draw-in groove.Correspondingly, the housing that the pressing place of gauge tap relates to also should provide the space of slip accordingly.After gauge tap slips into draw-in groove, gauge tap is locked between latch segment and housing, after removing external force, can not tilt because of the effect of return spring, thus keeps card and protruding lifting status, and wire spool is in free rotary state.
Further preferably, the interference side of the non-locking block of gauge tap also has a sliding bar, and enclosure interior correspondence is formed with the sliding tray slided for sliding bar.Thus make the slip of gauge tap more level and smooth, stable.
Preferably, card and protruding inside corners mate with ratchet outer rim.Coupling described here refers to that inside corners is identical with ratchet outer rim angle, thus can increase matching degree when the two is interfered, and reduces stressed.
Meanwhile, preferably card and protruding bottom surface ecto-entad are inclined-plane.Make it more reasonable at interference state lower stress, extend product service life.
After adopting technical scheme disclosed in this invention, rope is lock-out state under normal conditions, can not stretch arbitrarily, thus effectively prevent after pet shakes off, and the unsafe problems of generation regained fast by rope.Meanwhile, card and active force that is protruding and ratchet are firmly tangential, damage little, long product lifecycle.

Embodiment
In order to illustrate the present invention better, below we by reference to the accompanying drawings with specific embodiment come the present invention will be further elaborated.
Pet tractor as shown in Figure 3, comprise housing 8, the wire spool 2 with ratchet 1 be installed in housing, gauge tap 9, latch segment and return spring 11, described latch segment is a lever construction, its rotating fulcrum 101 is fixed on housing, lever two ends are respectively card and hold 102 and control end 103, wherein block and hold 102 to be formed with towards the card of ratchet and protruding 104, return spring 11 is fixed between the card of latch segment and end 102 and housing 8, control end 103 and the gauge tap 9 of latch segment are interfered, and pressing place 91 of gauge tap exposes to housing 8.
Preferably case inside is also provided with a draw-in groove 12 in the present embodiment simultaneously, and the interference side of the non-locking block of gauge tap also has a sliding bar 13, and enclosure interior correspondence is formed with the sliding tray 14 slided for sliding bar, and card and protruding 12 ecto-entads are inclined-plane.
Can see, under normally state, people does not operate gauge tap, gauge tap is in closed condition, card and the end 102 of latch segment are depressed by return spring 11, and control end 103 tilts, and card and protruding 104 is interfered with ratchet 1, wire spool is in locking state, and rope 15 can not free-extension.As shown in Figure 3, when rope is pulled, wire spool rotates, and ratchet and card and projection contacts, the rotary state of wire spool is stopped, rope stop motion.Thus, under normal force-free state, rope for traction can not free-extension, keeps certain length.
When needs cord retraction, as shown in Figure 4, gauge tap is pressed downwards, thus make the control end 103 of latch segment downward, due to lever principle, card and end 102 tilt, card and protruding 104 is lifted, depart from interference state with ratchet 1, wire spool can freely rotate, thus under the tractive of external force rope 15 free-extension.Under this state, be there is deformation by compression in return spring 11, and after pressing force removes, return spring 11 impels card and protruding 104 to be again returned to interference state with ratchet 1 by restoring force.
Conveniently operate, as shown in Figure 5, if after gauge tap is pressed downwards, continue force, impel it to slip into draw-in groove 12, gauge tap 9 is locked between the control end 103 of latch segment and housing 8, now, remove the active force to gauge tap, because gauge tap is locked, so the restoring force of return spring is not enough to pressure card and end 102, wire spool is in free rotary state all the time.
Comparison diagram 4 and Fig. 5, we see, sliding bar 13 sliding tray 14 of fitting slides, and will make so undoubtedly to slide more stable.
