Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
Present invention will be further explained below with reference to the attached drawings and examples:
As shown in Figs. 1-2, a kind of mini-tiller hand handle rotation limiting structure, including be mounted on the support 3 of mini-tiller front end with
And pin shaft 5, locating part and hand handle 1.
As shown in Figures 3 and 4, support 3, which is equipped with, vertically protrudes from the mandrel 4 on 3 surface of support, along its diameter on mandrel 4
Direction is penetratingly equipped with a pin hole, and the pin shaft 5 is inserted into pin hole and pin hole both ends are stretched out at 5 both ends of pin shaft respectively.It is also possible to
The pin hole is a blind hole, is extended outwardly from the center of circle of mandrel 4, so that the table of mandrel 4 is stretched out in one end end of pin shaft 5
Face.
Sleeve 2 at 1 connecting pin of hand handle is rotationally covered on mandrel 4 and is also entangled the pin shaft 5 together, the limit
For position part removably out of 2 outer wall of sleeve insertion sleeve 2, the part that the locating part protrudes into sleeve 2 when rotating hand handle 1 can be with pin
Axis 5 exposes two end in contact of mandrel 4 and rotation is obstructed.
In the present embodiment, due to sleeve 2 and 4 pivot bush unit of mandrel, the position setting of pin shaft 5 and limit element 6 is dexterously
So that hand handle 1 can only be less than 180 degree in the range of rotate, so as to avoid hand handle 1 360 degree of range inner circumferentials rotate with
Meaning property, prevents hand handle 1 from arbitrarily rotating, to guarantee the safety of operator.Total is simple and compact, safe and reliable,
It is adaptable.
Further, the both ends of the pin shaft 5 are all exposed mandrel 4, and its partial-length exposed must guarantee pin shaft 5 and limit
Position part can contact and limit its rotation, identical in the appropriate to the occasion partial-length for making pin shaft 5 expose mandrel 4 of actual fabrication, so that
Sleeve 2 preferably covers on mandrel 4, so that the rotation of hand handle 1 is more stable.To promote limit function, the pin hole is arranged two,
The angle of the central axis of described two pin holes is between 0-180 °.
Further, the external cylindrical surface of the mandrel 4 is equipped with groove of the circle towards 4 radial depressions of mandrel, the pin shaft 5
Both ends and locating part protrude into one end of sleeve 2 and be respectively positioned in the groove, setting groove one can make structure more
Compact, limit element 6 can also be led in groove to be moved downward more stable, so that 1 stability of rotation of hand handle, two carry out casing can be with core
Clearance fit between axis 4, greatly improves reliability.The locating part protrude into one end of sleeve 2 just with the groove
Slot bottom smooth contact, the both ends of the pin shaft 5 are contacted with 2 inner wall smooth of sleeve respectively, can make the inserting end of limit element 6
And the both ends of pin shaft 5 limit the relative position between mandrel 4 and sleeve 2 jointly, when rotation, functions well as guiding role, favorably
It is mixed when realize that not only flexible rotating is unlikely in rotation between sleeve 2 and mandrel 4 again to shake, securely and reliably, reduces contact and rubs,
Promote service life.
Further, the end face that the both ends of the pin shaft 5 and locating part protrude into 2 one end of sleeve is smooth and wear-resisting
Spherical surface reduces contact friction, promotes service life.
Further, the locating part includes bolt portion 601 and optical axis portion 602, and optical axis portion 602 is coaxial, is integrally connected
On the end face of the thread segment in bolt portion 601, locating part is screwed into the sleeve 2 by being threadedly engaged for thread segment, so that system
Make and is convenient to mount and dismount.
Further, two groups are additionally provided on the support 3 about the symmetrical taper hole of the pin shaft 5 or circular hole 9, every group of cone
Hole or circular hole 9 are arranged in camber line, and the camber line and mandrel 4 are concentric；The outside of the sleeve 2 integrally has a connecting tube
7, the connecting tube 7 is arranged in parallel with sleeve 2, and rotates to the position of a certain taper hole of 7 face of connecting tube or circular hole 9 in hand handle 1
When, it can be fixed on support 3 by the taper pin 8 cooperated with taper hole or circular hole 9, hand handle 1 is promptly fixed on phase when to need
It answers on position.
Further, the thread segment of the locating part carries out thread connection by being fixed on the nut of 2 outer wall of sleeve, to subtract
Few 2 thickness of sleeve (must just have enough thickness because to open up threaded hole sleeve 2), so that compact-sized light, cost
It is lower.
Further, it as shown in figure 5, the taper pin 8 is inserted into connecting tube 7 and protrudes into the taper hole or circular hole 9, bores
The top of pin 5 is connected by spring 804 with 805 end face of screw for being screwed in 7 top of connecting tube, to realize connecting tube and support 3
It is fixedly connected, it is solid and reliable after this mounting means connection.Taper pin can be processed or be used with integral type there are many form
Bolt 803 is assembled to form the composite structure of round tube or cylinder 802 and the frustum of a cone 801, which is used for and taper hole or circle
Hole 9 is mating.
Further, every group of taper hole or circular hole 9 be three and the connecting tube 7 and locating part be located at mandrel 4 it is same always
On diameter direction, to determine the position that will be fixed after the rotation of hand handle 1 rapidly.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
