Description

Transport vehicle eighty percent discount formula full sealing apparatus

Technical field:

The utility model belongs to the transport vehicle corollary apparatus, particularly a kind of transport vehicle eighty percent discount formula full sealing apparatus.

Background technology:

The transport trolley full sealing apparatus that generally uses in the society is wing open architecture at present, there are some problems in varying degrees in this structure, is subject to damage or distortion, wing open architecture as: the rear tailgate that takies interior space, original design and opens to both sides that the back influences chaufeur rearward vision and original device complex structure, weight is big.

Summary of the invention:

The purpose of this utility model is to provide a kind of transport vehicle eighty percent discount formula full sealing apparatus, to solve the problem that existing transport vehicle obturator exists.

Above-mentioned purpose adopts following technical proposals to realize:

A kind of transport vehicle eighty percent discount formula full sealing apparatus, include the Movable car cover of forming by forward and backward lid that is installed on the compartment, also include the four-bar linkage (1) that rocking arm, arm-tie, protecgulum and compartment constitute, the four-bar linkage (2) that protecgulum, bonnet, both sides, compartment pole and compartment constitute and the hydraulic actuator of control link mechanism, wherein

(1) Movable car cover is divided into protecgulum and bonnet with the compartment lateral cross section;

(2) four-bar linkage (1) is installed in the front portion, compartment, has the piston rod head that is promoted by the actuator cylinder piston, is hinged with rocking arm, and rocking arm one end and compartment are hinged, and the other end and arm-tie are hinged, and the arm-tie other end and protecgulum are hinged, and protecgulum and compartment are hinged;

(3) in the four-bar linkage (2), protecgulum and bonnet are hinged below the junction, and the bonnet both sides are hinged with both sides, compartment pole respectively, and both sides pole is hinged in compartment front part sides and compartment respectively.

Transport vehicle eighty percent discount formula full sealing apparatus, in both sides pole and hinged place, compartment, hinge hole is flat hole, constitutes a sliding pair with jointed shaft.

This transport vehicle eighty percent discount formula full sealing apparatus has the following advantages:

1. install safe and reliablely, in light weight, car bonnet is turned up or is closed steadily;

2. simple in structure, cost is low, is easy to apply;

3. environment purification guarantees traffic safety.

The specific embodiment:

Be described further below in conjunction with accompanying drawing:

Such as Fig. 1; Fig. 2; Fig. 3 and shown in Figure 5; The utility model haulage vehicle two folding full sealing apparatus include actuator cylinder 2; Actuator cylinder 2 is hinged at pin joint 4 with Rocker arm 5; When the support arm of actuator cylinder 2 is flexible; Driving Rocker arm 5 rotates around Rocker arm 5 and compartment 1 pin joint 3; The Rocker arm 5 other end and arm-tie 8 are hinged at pin joint 7; Arm-tie 8 other ends and protecgulum 11 are hinged at pin joint 9; Protecgulum 11 in addition not and compartment 1 front part sides hinged; Pin joint is respectively pin joint 6; Pin joint 17; Under Rocker arm 5 drives; Arm-tie 8 drives protecgulum 11 and rotates around the axial line 16 that pin joint 6 and pin joint 17 form; Protecgulum 11 is hinged by both sides, below, junction with bonnet 15; Pin joint is respectively pin joint 13 and pin joint 21; Pole 12 is hinged with bonnet 6 front part sides respectively with pole 20; Pin joint is respectively pin joint 14; Pin joint 22; Pole 71; The other end of pole 72 is hinged with the both sides of 1 front portion, compartment respectively; Pin joint is pin joint 10; Pin joint 18; Under bonnet 15 drives; Pole 71; Pole 72 is rotated around the axial line 19 that pin joint 10 and pin joint 18 form respectively, makes protecgulum 11 and bonnet 15 be turned up reposefully and incline and stand on the outside, 1 front upper place, compartment or launch and close 1 top in the compartment thereby reach.

As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6,1 anterior hinged in pole 12 and compartment 1 in the compartment, hinge-point is 10, hinged seat hole 23 is a prolate hole on the pole 12, form sliding pairs with jointed shaft on the compartment 1 24, in order to solve hinge-point 6 and hinge-point 13 connection line sizes add upper link point 13 and hinge-point 14 connection line size sums add upper link point 10 and hinge-point 6 connection line size sums greater than hinge-point 14 and hinge-point 10 connection line sizes; 1 anterior hinged in pole 20 and compartment 1 in the compartment, hinge-point is 18, hinged seat hole 25 is a prolate hole on the pole 20, form a sliding pair with jointed shaft on the compartment 1 26, in order to solve hinge-point 17 and hinge-point 21 connection line sizes add upper link point 21 and hinge-point 22 connection line size sums add upper link point 18 and hinge-point 17 connection line size sums greater than hinge-point 22 and hinge-point 18 connection line sizes; Thereby realization protecgulum 5 and bonnet 6 are turned up smoothly or are closed.
