Description
Technical field
The invention belongs to tractor field, relate to a kind of used with tractor hood lock, particularly relate to the compensation hood lock of a kind of used with tractor.
Background technology
Tractor hood is the covering of tractor head, and carry the effects such as the support of the protection of operating personnel and body and other elements is fixing, is the indispensable important component part of tractor.Hood lock ensures hood and the firm fixing vitals of body.At present, used with tractor hood lock main Types has three kinds: twin-lock button, bearing pin tight-holding type and torsion entry type.The advantage of twin-lock button hood lock is that structure is simple, low cost of manufacture.Shortcoming is that locking effect is poor, and four-bar mechanism is unstable, the locking dismounting of cottor pin is complicated, the some effects that leak outside outward appearance; The advantage of bearing pin tight-holding type hood lock is compact in design, lock firm, sealed easy to operate, outward appearance good.Shortcoming is single-point hard contact, interstitial vibration noise is large, complex structure cost is high; The advantage reversing entry type hood lock is that structure is simple, easy to operate.Shortcoming is that application conditions limitation is strong.The general character shortcoming of above-mentioned hood lock is: rigid connection, sealed gap is uncompensated, tractor work time, vibration is strong, hood is fragile.
Summary of the invention
The object of the invention is to solve current tractor when working under the bad working environments of field, front opening-closing type hood due to sealed gap uncompensated and cause the problem damaged, thus provide a kind of compensation hood lock of used with tractor with autocompensation locking function.
Technical scheme of the present invention is: the compensation hood lock of used with tractor, comprises the lower lock tooth soldering member in tooth soldering member of locking, lower lock tooth assembly, packing ring, cottor pin, U-shaped bracing frame, axle, spacer pin, return spring, push rod, support set, nut, button; Tooth soldering member of locking is welding integral, and the U-shaped bracing frame in lower lock tooth assembly is main backstop, and support set is fixed on U-shaped bracing frame; Axle runs through and is fixed in U-shaped bracing frame sidepiece; Spacer pin is fixed on U-shaped bracing frame, and return spring is articulated in U-shaped bracing frame both sides; Lower lock tooth soldering member bottom and axle hinged; Pushing rod sleeve is contained in support set, and bending end connects lower lock tooth soldering member bottom.
The straight end head of push rod is bolted with nut and button, and bending end is provided with packing ring, cottor pin.
Following beneficial effect can be reached: because compensation hood lock belongs to linear contact, it is firm to lock after the present invention adopts technique scheme; Adopt compensation locking mode, gapless; Elasticity is located, and protective value is good; Simple operation, good looking appearance; Structure is simple, with low cost.

Fig. 1 is the structural representation of the compensation hood lock of used with tractor of the present invention;
Fig. 2 is the self-locking process schematic of the compensation hood lock of used with tractor of the present invention;
Fig. 3 is the manual unlocking process schematic of the compensation hood lock of used with tractor of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.As shown in Figure 1, the compensation hood lock of used with tractor, comprises the lower lock tooth soldering member 1 in the tooth soldering member A that locks, lower lock tooth assembly B, packing ring 2, cottor pin 3, U-shaped bracing frame 4, axle 5, spacer pin 6, return spring 7, push rod 8, support set 9, nut 10, button 11; The tooth soldering member A that locks is welding integral, and the U-shaped bracing frame 4 in lower lock tooth assembly B is main backstop, and support set 9 is fixed on U-shaped bracing frame 4; Axle 5 runs through and is fixed in U-shaped bracing frame 4 sidepiece; Spacer pin 6 is fixed on U-shaped bracing frame 4, and return spring 7 is articulated in U-shaped bracing frame 4 both sides; Lower lock tooth soldering member 1 bottom and axle 5 hinged; Push rod 8 is sleeved in support set 9, and bending end connects lower lock tooth soldering member 1 bottom.The straight end head of push rod 8 is bolted with nut 10 and button 11, and bending end is provided with packing ring 2, cottor pin 3.
The tooth soldering member A that locks is welding integral, is arranged in tractor hood, and lower lock tooth assembly B is arranged on tractor forebay.Compensation hood lock before the tractor being provided with rubber door-inhale, opening-closing type hood is installed and used.Rubber door-inhale plays the effect of limit lateral degree of freedom and resiliency supported tractor hood weight, and the present invention then can play the degree of freedom effect on restriction folding direction.
Lower lock tooth assembly B is made up of multi-part, and U-shaped bracing frame 4, support set 9 support overall structure, and lower lock tooth soldering member 1 can rotate around axle 5; Push rod 8 connects lower lock tooth soldering member 1, button 11 also can do straight reciprocating motion along support set 9 inwall; All the other component play fastening limit function.
The present invention mainly comprises two job steps: one is self-locking process, and two is manual unlocking processes.
As shown in Figure 2, compensation hood lock self-locking process is: the tooth soldering member A that locks does descending motion around back shaft with radii fixus with hood.Close to locking in process, tooth soldering member A and the lower lock tooth assembly B inclination flank of tooth are separately pressed close to gradually, after tooth soldering member A flank of tooth acute angle chisel teeth of locking laminating lower lock tooth assembly B flank of tooth acute angle chisel teeth, promote lower lock tooth soldering member 1 and move backward around axle 5.After obtaining space, the tooth soldering member A that locks continues to move downward, and embeds bottom door-inhale, movement ceases until hood door fixes bulb.Meanwhile, lower lock tooth soldering member 1 fits tightly with the tooth soldering member A flank of tooth of locking all the time under the effect of return spring 7.After each complete profile of tooth of the tooth soldering member A flank of tooth of locking is passed through, the hook tooth that its direction of motion is contrary and the identical structural interlock on lower lock tooth soldering member 1, block the opposite direction motion of the tooth soldering member A that locks.So far self-locking process terminates.
As shown in Figure 3, compensation hood lock manual unlocking process is: with finger push button 11, and button 11 drives lower lock tooth soldering member 1 to move along pushing direction around axle 5 by push rod 8.This locks tooth soldering member 1 at present and departs from gradually with tooth soldering member A profile of tooth of locking, and after departing from completely, lifts hood and departs from lower lock tooth assembly B.Release button 11, lower lock tooth soldering member 1 is repositioned to spacer pin 6 place under return spring 7 acts on.Button 11, push rod 8 be return under lower lock tooth soldering member 1 drives, for next time sealed ready.So far manual unlocking process terminates.
In tractor work environment, road conditions of jolting can cause tractor hood inertia to press down, and door-inhale is elastic deformation thereupon.When the gap value that it produces meets the stroke of a profile of tooth; the present invention will compensate locking by above-mentioned self-locking process; tractor hood and tractor frame are fastened as a whole all the time, avoid both relative impact, protect tractor hood to greatest extent.
