Abstract
The invention discloses a gear control lever locking device of a speed-changing gear box, which comprises a control lever and a gear plate. A connector is installed on the control lever and can directionally bend the upper part of the control lever relative to the lower part of the control lever; the gear plate is provided with a gear slot and a locating slot; when in use, the control lever can leave the gear slot and fall into the locating slot for carrying out position locking so that the control level can not slide along the gear slot, therefore, the trip-stop problem of the speed-changing gear box can be solved.
Description
Technical field
The present invention relates to a kind of speed-changing gear box, be specifically related to a kind of speed-changing gear box gear control device.
Technical background
Known rotary cultivator, microtilling machine, reaper generally are equipped with speed-changing gear box, and the speed-changing gear box gear control device comprises gear operating lever and gear plate, and operating handle is moved into the diverse location of gear plate, the different operating state of may command speed-changing gear box.
But, when speed-changing gear box is subjected to the Low Medium Frequency impact, as the rotary blade of miniature rotary cultivator when the work, or walking is on rugged road the time, the capital produces Low Medium Frequency to speed-changing gear box and impacts, the problem of trip stop appears causing along the slip of gear groove in gear operating lever easily, the engagement of speed-changing gear box internal gear changes suddenly voluntarily, be easy to tooth to occur bumping, beat the tooth phenomenon, the hazardous condition that the unexpected regression of anti-engagement perhaps occurs, damage gear-box and initiation potential, have a strong impact on working efficiency and work safety.
Certainly, declutch shift shaft locating slot service wear in speed-changing gear box occurring, or retaining spring elastic force weakens, or place kick is during because of phenomenons such as the foul filling are stuck, gear operating lever also occurs along the slip of gear groove easily and causes the trip stop problem, damages gear-box and initiation potential.
Summary of the invention
The present invention aims to provide a kind of gear-box gear operating lever locking device, can the working position of operating handle be locked, and makes the gear operating lever at work can not be along the gear groove from line slip, thereby solves the trip stop problem of speed-changing gear box.
The technical solution used in the present invention is: gear control level locking device of speed-changing gear box, comprise operating handle and gear plate, mounted connector on the operating handle, connector can make relative operating handle bottom, operating handle top carry out the orientation bending, and gear groove and locating slot are set on the gear plate.
Locating slot is arranged on the groove of operating handle gear positions one side, connector connects the operating handle upper and lower respectively, can make operating handle top and operating handle bottom be in straight line to positive status, also can allow relative operating handle bottom, operating handle top in the specific suitable angle of direction bending, make operating handle successfully leave the gear groove and fall in the locating slot.
When advancing grade, at first operating handle is moved to gear positions along the gear groove of gear plate, more relative operating handle bottom, operating handle top is bent, make operating handle leave the gear groove and fall in the locating slot.Enter operating handle in the locating slot and be subjected to the qualification of locating slot, the position locks relatively, even impact being subjected to Low Medium Frequency, or other factors is when influence, also is difficult to the disengaging locating slot working position of slipping away, thereby has solved the problem of trip stop well.
When moving back grade, at first relative operating handle bottom, operating handle top is dialled directly, make operating handle break away from locating slot and get back in the gear groove, promote operating handle again and in the gear groove, move, make the speed-changing gear box gear of deactivating.
Above-mentioned connector can be to comprise slide block that is fixed on termination, operating handle top (or bottom) and the chute that is fixed on termination, operating handle bottom (or top), and slide block is nested in the chute, and connects chute by bearing pin.Slide block can rotate around bearing pin in chute, makes operating handle top carry out the orientation bending in the operating handle bottom relatively.Further technological scheme, angle between the bottom surface of above-mentioned chute and the end face of slide block is 0-20 °, also comprise the angle within forming 20 ° between the part end face of the part bottom surface of chute and slide block, both can allow relative operating handle bottom, operating handle top in the specific suitable angle of direction bending, making operating handle successfully leave the gear groove falls in the locating slot, can allow again operating handle top can be returned to operating handle bottom straight line to positive status, can also limit operating handle top and reciprocal knuckle is formed at the operating handle bottom, can allow operating handle move the more smooth and easy convenience of use.
Above-mentioned connector can also be to comprise two axle sleeves that are separately fixed at operating handle top, operating handle lower side, and two axle sleeves together are sleeved on the bearing pin.Rotate around bearing pin on operating handle top, can realize bending to a side positioning.
Above-mentioned connector also can be to comprise two tenons that are separately fixed at operating handle top, termination, operating handle bottom, and two tenons are provided with inclined end face and also together are sleeved on the bearing pin.Rotate around bearing pin on operating handle top, can realize bending to a side positioning.
The present invention is mounted connector on operating handle, make relative operating handle bottom, operating handle top carry out the orientation bending, and corresponding locating slot is set on the gear plate, allowing operating handle leave the gear groove falls into and carries out locking position in the locating slot, the operating handle work gear positions that can not slip away voluntarily at work, thus the trip stop problem of speed-changing gear box solved.
