In the illustrative examples of the sweeper provided at the utility model, back door can be symmetrically arranged with two cover door body locking devices.
Illustrate the method for operating of a specific embodiment of the door body locking device that the utility model provides below:
Door opening process (as shown in FIG. 1 to 3):
The piston end retraction of hydraulic jack 1, the lateral surface driving sliding pin 2 and latch 4 to be parallel to a body 8 moves up, the wedge structure of latch 4 bottom moves upward and departs from the snap close mouth 61 (as shown in Figure 2) of latch plate 6, when the guiding gudgeon 3 of sliding pin 2 rises to the apical position of gathering sill 31, the piston end retraction of hydraulic jack 1, namely door body 8 is driven to be fixedly connected on the top pin joint Unscrew (as shown in Figure 3) of dustbin casing 7 along it, now the guiding gudgeon 3 of sliding pin 2 is in the apical position of gathering sill 31 due to the effect of door body 8 self gravitation always, dustbin casing 7 can be opened after opening to extreme position and topple over loop, dustbin casing 7 front end is dumped oil cylinder jack-up and dumps rubbish.
Door closing procedure:
Dustbin casing 7 is in level, the piston end of hydraulic jack 1 stretches out, door body 8 is due to self gravitation effect whereabouts, the piston of hydraulic jack 1 is held door body 8 and is slowly fallen, now the guiding gudgeon 3 of sliding pin 2 is in the apical position of gathering sill 31 always, door body 8 continues to fall, namely vertical state is in after the weather strip 9 of door body 8 medial surface contacts dustbin casing 7, door body 8 Gravitative Loads disappears, the piston end of hydraulic jack 1 continues to stretch out, promotion sliding pin 2 and latch 4 are parallel to a body 8 and move down, namely the stepped wedge structure of latch 4 bottom is inserted in the snap close mouth 61 of latch plate 6, door body 8 under the guiding squeezing action of the stepped wedge structure of latch 4 bottom, press close to dustbin casing 7 and the weather strip 9 of compacting medial surface realizes sealing, snap in after in snap close mouth 61 when latch 4 falls to vertical snap close face 41, namely spring lock closed procedure is completed.
In order to increase the uniform compaction degree of a body 8 medial surface weather strip 9 further, prevent from the local distortion because of door body 8 from causing cannot seal, as further improvement of the utility model scheme, hydraulic jack 1, sliding pin 2, sliding pin guide strip 3, latch 4, latch fairlead 5 and latch plate 6 all can arrange two covers, are symmetricly set on car body rear end face.
By the description of each embodiment above-mentioned, the door body locking device that the utility model provides can be derived, at least have the following advantages:
1) wedge structure of latch 4 bottom is stepped owing to being arranged to, namely wedge structure inclined-plane is arranged the vertical snap close face 41 that at least one vertical direction is parallel to a body 8, i.e. positioning step, therefore in spring lock closed procedure, snap in after in snap close mouth 61 when latch 4 falls to vertical snap close face 41, vertical snap close face 41 can limit latch 4 and bounce back because of the opposite force effect by lozenges, even if still can locking door body 8 when not installing hydraulic lock additional or hydraulic jack 1 reveals or lost efficacy, prevent sewage water clock.
2) installing hole upper end of sliding pin 2 or lower end being provided with one end that length adjustment mechanism 22 or latch plate 6 level are fixedly installed in bottom dustbin casing 7 is set to the strip hole of fore-and-aft direction, therefore conveniently can adjust the press seal degree of door body 8 medial surface weather strip 9.
In sum, the door body locking device that the utility model provides, structure is simply easy to realize, and can realize firm locking effect, prevents sewage water clock.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
