Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, the present embodiment provides a medical waste transportation vehicle with a flip-open cover function, including a hopper 1, a frame 2, a first transmission mechanism 3, and a cover plate 4, wherein the hopper 1 is used for loading materials, the frame 2 provides a support for the hopper 1, the first transmission mechanism 3 connects the frame 2 and the cover plate 4 and drives the cover plate 4 to rotate when the frame 2 dumps the hopper 1, the cover plate 4 is used for covering the hopper 1 to seal the hopper 1, and wherein:

hopper 1 is articulated with

support

2, 3 drive ratios of first drive mechanism are positive numbers for when hopper 1 emptys, apron 4 outwards rotates for hopper 1, thereby make hopper 1 upper portion uncovered, 3 power input ends of first drive mechanism rotate with support 2 and be connected or fixed connection, apron 4 is articulated with hopper 1, and with 3 power output ends fixed connection of first drive mechanism, it should be said that, in order to make first drive mechanism 3 can drive apron 4 to rotate when hopper 1 rotates and emptys, 3 power output ends rotation axis of first drive mechanism should be coaxial with 1 rotation axis of hopper.

Specifically, referring to fig. 1 and fig. 2, in the present embodiment, the first transmission mechanism 3 is a chain transmission mechanism, the first transmission mechanism 3 includes a first sprocket 31, a second sprocket 32 and a chain 33, the chain 33 is engaged with the first sprocket 31 and the second sprocket 32, the first sprocket 31 is rotatably connected or fixedly connected with the bracket 2, and the second sprocket 32 is fixedly connected with the hopper 1.

With continuing reference to fig. 1 and 2, the principle of the cover plate 4 of the medical waste transport cart with flip cover function provided in the present embodiment being rotated to open when the hopper 1 is dumped will be explained in detail as follows: when first sprocket 31 and support 2 fixed connection, first sprocket 31 is unable to rotate, hopper 1 is rotatory to be emptyd, hopper 1 and second sprocket 32 are anticlockwise rotatory around first sprocket 31 this moment, use hopper 1 as the reference system, first sprocket 31 is then relative hopper 1 clockwise rotation, drive second sprocket 32 for hopper 1 clockwise rotation under the effect of chain 33, the function that apron 4 was opened has been realized, first sprocket 31 and second sprocket 32 turn to the same, therefore first drive ratio is the positive number, if it turns to conversely, apron 4 is for hopper 1 anticlockwise rotation, apron 4 rotates to hopper 1 internal, can't realize hopper 1 uncovered. It will be readily appreciated that the first transmission 3 is not limited to the use of a chain 33, and that this function may be achieved using a gear set, belt, etc.

It should be noted that when the hopper 1 needs to be loaded with materials, the cover plate 4 also needs to be rotated to open, but at this time, the hopper 1 cannot be rotated, so that the first chain wheel 31 is rotatably connected with the bracket 2 to ensure that the first transmission mechanism 3 and the cover plate 4 can rotate freely. In order to realize the switching between the fixing and the rotation of the first chain wheel 31 and the bracket 2, the medical waste transport cart with the flip-open function provided by the embodiment further includes a locking mechanism 5, the locking mechanism 5 includes a first gear 51, a rack 52, a spring 53 and a push rod 54, the rotating shaft of the first gear 51 is coaxial with the rotating shaft of the hopper 1 and is fixedly connected with the first chain wheel 31, the rack 52 includes a meshing portion 521, a sliding portion 522 and a resisting portion 523, the included angle between the meshing portion 521 and the sliding portion 522 is an acute angle or a right angle, i.e. the included angle is greater than 0 ° and less than or equal to 90 °, two ends of the sliding portion 522 are respectively and fixedly connected with the meshing portion 521 and the resisting portion 523, the meshing portion 521 is meshed with the first gear 51, the sliding portion 522 is slidably connected with the bracket 2, the resisting portion 523 is contacted with the push rod 54, the spring 53 is arranged along the sliding direction of, the push rod 54 is hinged to the bracket 2. When the first gear 51 is engaged with the engaging portion 521, the first gear 51 is locked, that is, the first chain wheel 31 is fixedly connected with the bracket 2, and when the first gear 51 is disengaged from the engaging portion 521, the first chain wheel 31 is rotatably connected with the bracket 2.

Referring to fig. 2 and 3, the operation principle of the locking mechanism 5 of the medical waste transport cart with flip cover function provided in this embodiment will be specifically described as follows: since the first sprocket 31 and the first gear 51 are coaxially and fixedly connected, the first sprocket 31 and the first gear 51 are in the same motion state, under the action of the elastic force of the spring 53, the rack 52 slides toward the first gear 51 until the meshing part 521 abuts against and meshes with the first gear 51, and because the rack 52 can only slide along the direction of the spring 53 and cannot move in the direction tangential to the first gear 51, at this time, the first gear 51 is locked by the rack 52 and cannot rotate, the first sprocket 31 fixedly connected therewith cannot rotate, the push rod 54 is pushed, the push rod 54 pushes the abutting part 523, the rack 52 also moves, the meshing part 521 gradually disengages from the meshing with the first gear 51, at this time, the first gear 51 is not locked any more, and the first gear 51 and the first sprocket 31 can rotate. When the push rod 54 is released, the abutting portion 523 is no longer acted by the force of the push rod 54, and the rack 52 is returned by the spring 53 to lock the first gear 51 again.
