Abstract

The utility model discloses a tiller handle with a safety device, which comprises a handle, and is characterized in that the handle is provided with a lock catch, one end of the lock catch penetrates through a hole in the handle to become a rotatable free end, the other end of the lock catch is fixed, a concave opening is arranged in the lock catch and matched with the wall of the handle surrounding the hole, and the wall of the handle is clamped into the concave opening. In the utility model, the tiller handle is provided with the safety lock catch, and the rotation of the handle is limited by the safety lock catch, so as to prevent the handle from being rotated due to misoperation or unintended collision, prevent a tiller from moving forwards or backwards when the handle is operated by mistake, avoid collision between the tiller and persons and objects in front of or behind the tiller, avoid the damage to the tiller or other objects and persons, and effectively eliminate serious safety hidden danger of the tiller.

Description

A kind of tiller handle with safety device

Technical field

The utility model relates to a kind of handle of agricultural tillage machine arm assembly, relates in particular to the higher tiller handle with safety device of a kind of security performance.

Background technology

The arm assembly of agricultural tillage machine mainly plays guide effect, and operating personnel control the traffic direction of whole Miniature cultivator used on higher by arm assembly, thereby is controlling the rotary tillage orientation of rotary blade group.Handle on the arm assembly, be connected with the control drag-line, the operator spurs the control drag-line by rotating handles, and then the unlatching by devices such as control drag-line solenoidoperated cluthes, throttles or close and the size of open degree etc., controls the agricultural tillage machine and produces farming and move.

The handle of the agricultural tillage machine of prior art, normally be connected on the arm assembly turnably, rotate nimbly and freely, the stopping means (safety device) that limits its rotation is not set on handle, make the rotation of handle not be subjected to any restriction substantially, in the handle maloperation or when being collided unintentionally, handle equally correspondingly rotates, drive clutch or throttle drag-line and produce action, tiller is advanced or retreat, make tiller may with the object of its front or back, people etc. produce collision, form either large or small accident, tiller self or other objects, personnel come to harm.Especially when the handle maloperation retreated tiller, usually wounding stood in the operating personnel of arm assembly front, even made operating personnel seriously injured because of being subjected to fierce bump.Die, do not have the handle of safety device, have serious potential safety hazard, can not satisfy requirement of safe production.

The utility model content

At the prior art above shortcomings, the utility model provides a kind of tiller handle with safety device that misoperation, security performance are greatly improved that can not produce in the handle maloperation or when being collided unintentionally.

A kind of tiller handle with safety device that the utility model provides comprises handle, it is characterized in that: snap close is set on handle, and an end of snap close passes the hole on the handle, becomes rotating free end; The other end of snap close is fixed; Recess is set on snap close, and recess cooperates with the wall of hole handle on every side, and the wall of handle snaps in the recess.

Further feature is: stage clip is set below snap close, and stage clip 3 withstands on the snap close.

Described snap close is a rubber-like sheet spring.

The wall of the handle around the hole is the overhead kick body, and the overhead kick physical efficiency is inserted in the recess and cooperated.

The beneficial effects of the utility model: the utility model is provided with secure latch on the tiller handle, limit the rotation of handle by secure latch, can prevent that handle from rotating in maloperation or when being collided unintentionally, prevent that handle from advance tiller or retreat when maloperation, avoid people, the object of forward and backward with it of tiller to produce collision, avoid tiller self or other objects, personnel to come to harm, effectively eliminate the serious potential safety hazard that tiller exists.

Description of drawings

Fig. 1 is the front view of the utility model handle;

Fig. 2 is the cutaway view of Fig. 1;

Fig. 3 is second kind of example structure schematic diagram of the utility model.

Among the figure, 1-handle, 2-snap close, 3-stage clip, 4-latch, 5-locking nut, 6-drag-line line seat, 7-drag-line, 8-adjusting bolt, 11-hole, 12-overhead kick body, 21-recess.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.

As Fig. 1, shown in Figure 2: a kind of tiller handle with safety device, comprise handle 1, drag-line line seat 6 is arranged on the handle 1, the locking nut 5 of drag-line 7 by drag-line line seat 6 two ends is arranged on the drag-line line seat 6 and (is provided with as required and regulates bolt 8 to adjust the length of drag-line 7, make the elasticity of drag-line 7 suitable), drag-line 7 passes drag-line line seat 6, the one end is connected with handle 1, the other end is connected to the clutch of tiller, on the device such as throttle, as solenoidoperated cluthes, devices such as throttle are opened or are closed and the control cord of the size of open degree, drive drag-line 7 is strained or is loosened when handle 1 rotates, and plays control action.Above as prior art, be not further described at this.

Improvement of the present utility model, be that snap close 2 is set on handle 1, one end of snap close 2 passes the hole 11 on the handle 1, become rotating free end, the other end of snap close 2 is fixed, fixing by being connected on handle 1 or the drag-line line seat 6, is the connected mode that adopts latch 4 among the figure, by latch 4 with the snap close 2 detachable bottoms that are connected handle 1; Recess 21 is set on snap close 2, and recess 21 cooperates with the wall of hole 11 handle 1 on every side, and it is interior and spacing that the wall of handle 1 snaps in recess 21, the rotation of restriction handle 1.

In order to strengthen the elasticity of snap close 2, stage clip 3 is set below snap close 2, stage clip 3 withstands on the snap close 2, makes the recess 21 of snap close 2 and the good gripping orientation of wall maintenance of handle 1.

Referring to Fig. 3, if snap close 2 is good springiness own, rubber-like sheet spring (spring leaf), just can be without stage clip 3, snap close 2 still has elasticity preferably, satisfies needs of the present utility model.

As further improvement of the utility model, the wall of the handle 1 around the hole 11 is set to overhead kick body 12, and overhead kick body 12 can insert in the recess 21 and cooperate, make

recess

21 and 12 maintenances of overhead kick body good cooperate gripping orientation, snap close 2 is cooperated closely with handle 1.

During use, pull the restriction of releasing to handle 1 downwards, ability swing handle 1 could be controlled tiller and produce action this moment.The free end release of moving snap close 2, the overhead kick body of handle 1 is withdrawed from the recess 21 of snap close 2, if snap close 2 is not withdrawed from the wall of handle 1 in the recess 21 of snap close 2, then can not swing handle 1, can prevent that handle 1 from rotating in maloperation or when being collided unintentionally, snap close 2 plays the effect of safety device.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
