Description

Technical Field

[0001] The present application relates to the technical field of garbage can transfer, and in particular to a cart for transferring garbage cans. Background Art

[0002] Trash cans are containers for holding garbage and waste. In hospitals, trash cans can be seen everywhere. A lot of domestic waste and medical waste are generated in hospitals every day. When the trash cans are full or nearly full, cleaning staff are required to move them to the waste storage point for dumping. Some trash cans have wheels at the bottom and can be moved to the destination by wheels, while some trash cans do not have wheels at the bottom, so cleaning staff need to bend down to move them to a trolley and transport them to the destination. When there are many trash cans, they need to bend down frequently to move them, which not only consumes more physical strength of cleaning staff, but also long-term bending can cause damage to the lumbar intervertebral disc and cause lumbar disc herniation. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a trolley for transporting garbage bins, which can reduce the long-term bending of cleaning staff and reduce the situation of lumbar diseases caused by bending.

[0004] In order to solve the above technical problems, this application adopts the following technical solutions:

[0005] A cart for transporting a garbage can comprises a base, a mouth is formed at the front end of the base, a plurality of guide rods are provided on the base, a slidable lifting plate which is consistent with the structure of the base is provided on the guide rods, a supporting assembly which contacts the side wall of the garbage can is provided on the lifting plate, and a scissor jack which drives the lifting plate to move up and down is also provided on the base. The scissor jack on the base can control the rise and fall of the lifting plate, the outside of the garbage can is clamped by the bayonet on the base and the lifting plate, the supporting assembly fits with the outside of the garbage can, and when the lifting plate moves upward, the supporting structure clamps the garbage can and lifts it upward until the bottom of the garbage can leaves the ground, so that it can be transported away.

[0006] In some embodiments, the side surface of the lifting plate is provided with more than one through hole.

[0007] In order to achieve the support and lifting of the trash can, in some embodiments, the supporting assembly includes a plurality of telescopic rods, and the plurality of telescopic rods are respectively arranged in the through holes on the side of the lifting plate. One end of the telescopic rod located on the inner side of the lifting plate is connected to a diagonal support plate, and the other end of the telescopic rod is provided with a baffle. The current trash can is usually a structure with a larger top and a smaller bottom, and its side is inclined. After the diagonal support plate contacts the side of the trash can, the diagonal support plate moves upward, but is restricted by the inclined surface of the side of the trash can and cannot move upward. If the diagonal support plate continues to move upward, the trash can will be lifted.

[0008] Compared with the prior art, the present application achieves at least the following beneficial effects: the present cart can be directly inserted into the outside of the trash can, and contact the outer wall of the trash can through the supporting assembly, and then the scissor jack lifts the lifting plate and the supporting assembly. After the diagonal support plate of the supporting assembly contacts the outer wall of the trash can, because the outer wall of the trash can has a certain inclination angle, when the diagonal support plate moves upward, it will stick to the outer wall of the trash can. When the supporting assembly continues to rise, it will lift the trash can and separate it from the ground. This can not only reduce the number of times it is carried and save physical strength, but also reduce the number of times the cleaning staff bends over, reducing adverse conditions such as lumbar muscle strain caused by long-term bending.

DETAILED DESCRIPTION

[0016] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0017] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0018] The defect of the prior art that it takes a lot of physical effort to carry a trash can without wheels at the bottom and that it requires frequent bending over, which causes back pain, is addressed. After careful analysis, the inventor found that the main reason for the above problems is that some trash cans without wheels at the bottom are usually used indoors. If these trash cans are filled with medical waste, it may not be possible to directly take out the trash bags inside, or it is not convenient to put on the trash bags. In this case, the entire trash can needs to be transported to a designated waste destruction point for unified treatment. The height of this trash can is generally 30-50 cm. When an adult transfers it, he may need to bend over to lift it. This makes the overall weight heavier when there is more waste in the trash can. When carrying multiple pairs of trash cans, it takes more effort to move them manually. Secondly, frequent bending over can easily cause diseases such as strain on the waist. Based on the above analysis, the inventor has made structural improvements to the tools for carrying trash cans.

[0019] like Figure 1-4 As shown, the present application is a trolley for transporting garbage bins, which includes a base 5 made of a metal square tube, with an opening opened at the front end of the base 5 so that the base 5 is generally in a U-shaped structure, and four guide rods 4 are welded to the top of the base 5, which are roughly distributed at the four corners of the base 5, and the top surfaces of the guide rods 4 are provided with flanges for limiting, and the guide rods 4 are provided with a slidable lifting plate 3 which is consistent with the structure of the base 5, wherein, in order to improve the smoothness of the lifting plate 3 sliding on the guide rods 4, the lifting plate 3 is sleeved on the holes on the guide rods 4 and welded with self-lubricating guide sleeves; the lifting plate 3 is provided with a supporting assembly in contact with the side wall of the garbage bin; the base 5 is also provided with a scissor jack 8 for driving the lifting plate 3 to move up and down. The scissor jack 8 on the base 5 can control the rise and fall of the lifting plate 3. The outside of the trash can is clamped by the bayonet on the base 5 and the lifting plate 3, and the supporting assembly fits with the outside of the trash can. When the lifting plate 3 moves upward, the supporting structure clamps the trash can and lifts it upward until the bottom of the trash can leaves the ground, and then it can be transported away.

[0020] The bottom of the base 5 is provided with wheels 6 to facilitate the cart to be transported away.

[0021] The lifting plate 3 is used to drive the supporting assembly to move up and down. Taking into account the different sizes of trash cans, in order to adapt to trash cans of different sizes, the side of the lifting plate 3 is provided with through holes not limited to one; the supporting assembly includes a plurality of telescopic rods 10 (three are used in this embodiment), and the plurality of telescopic rods 10 are respectively arranged in the through holes on the side of the lifting plate 3. One end of the telescopic rod 10 located on the inner side of the lifting plate 3 is connected to a diagonal support plate 11, and the other end of the telescopic rod 10 is provided with a baffle 9. The current trash can is usually a structure with a large top and a small bottom, and its side is inclined. The diagonal support plate 11 contacts the side of the trash can. Because the trash can is a structure with a large top and a small bottom, the diagonal support plate 11 moves upward, and is restricted by the side of the trash can, and the diagonal support plate 11 cannot move upward. If the diagonal support plate 11 continues to move upward, the trash can will be lifted.

[0022] When the size of the trash can is small, the telescopic rod 10 can be pushed toward the inner side of the lifting plate 3 to narrow the diagonal support plate 11 inwardly, so that the diagonal support plate 11 can fit the side wall of the small-sized trash can.

[0023] The other end of the telescopic rod 10 is provided with a stopper 9 of an annular gasket to prevent the telescopic rod 10 from coming out. A screw hole is provided on the end face of the telescopic rod 10, and a screw 12 is screwed in the screw hole to fix the stopper 9.

[0024] Since the telescopic rod 10 can move, if the supporting mechanism is not fixed, when a trash can of a smaller size is transported, the telescopic rod 10 will move to both sides during the upward movement of the diagonal support plate 11, so that the diagonal support plate 11 moves with it and cannot support the trash can. For this reason, a locking mechanism 13 for limiting the movement of the telescopic rod 10 is also provided on the lifting plate 3. The locking mechanism 13 includes two symmetrically distributed ear plates 1301 welded on the lifting plate 3, a rotating shaft 1303 is provided between the two ear plates 1301, and a locking block 1306 is provided on the rotating shaft 1303. The locking block 1306 is cylindrical, such as Figure 3 As shown, its axis is biased upward, while the lower part is more protruding, and this position can be used to press the top surface of the telescopic rod 10; the side wall of the locking block 1306 is provided with a tightening handle 1304, which can be pressed down to lock, or lifted up to loosen.

[0025] In order to enable the locking block 1306 to contact the telescopic rod 10, a hollow hole connected to the through hole on the side of the lifting plate 3 is opened between the two ear plates 1301. In this way, the locking block 1306 can be driven by the elastic handle 1304 to swing and contact or separate from the telescopic rod 10.

[0026] In order to prevent the elastic handle 1304 from being pressed down too much, which would cause the bottom of the locking block 1306 and the top surface of the telescopic rod 10 to separate, a limiting groove 1302 is provided on the ear plate 1301, and a limiting pin 1305 is provided on the side wall of the elastic handle 1304, and the limiting pin 1305 is arranged in the limiting groove 1302.

[0027] The scissor jack 8 raises or lowers its own platform by means of a screw drive. In order to reduce the manual bending to drive the scissor jack 8 to work, at one end of the screw of the scissor jack 8, a reference Figure 1 The left end is connected with a motor 7, and a motor 7 support plate 501 for supporting the motor 7 is welded on the seat.

[0028] The structure of the scissors jack 8 includes a screw rod, a moving block with a threaded hole, a support arm and a platform. Two moving blocks are sleeved on the screw rod, the moving blocks are connected to the support arms, and the other end of the support arms is connected to the platform. The scissors jack 8 is an existing structure and will not be described in detail here.

[0029] In this embodiment, if Figure 4 As shown, two fixing blocks 15 are provided on the vehicle seat, a hole is opened in the middle of the fixing block 15, a shaft sleeve 301 or a bearing is provided in the hole, and a screw rod is provided in the shaft sleeve 301 or the bearing, so that the two moving blocks on the screw rod of the scissor jack 8 can be lifted so that they do not contact the top surface of the vehicle seat, thereby reducing friction.

[0030] A push-pull handle 2 is provided on the top surface of the rear side of the base 5. Some buttons 1 for controlling the rotation of the motor 7 are provided on the push-pull handle 2. A configuration box 14 for placing a power supply and a controller is also provided on the top surface of the rear side of the base 5.

[0031] When using the cart, the initial position of the lifting plate 3 is as follows Figure 1 and Figure 2 As shown, the seat and the lifting plate 3 are inserted into the trash can to be transported, and then the button 1 on the push-pull handle 2 is pressed to rotate the motor 7, and the lifting plate 3 drives the supporting assembly to move upward. When the supporting assembly moves upward, its inclined support plate 11 gradually contacts the outer wall of the trash can. After the contact is complete, as described above, the inclined support plate 11 drives the trash can to move upward. When the bottom of the trash can leaves the ground, the motor 7 is controlled to stop rotating by another button 1. At this time, the state of the cart is as follows Figure 5 As shown, the trash can can be transported away. If a second trash can is transported, the first trash can needs to be put down first, so that the lifting plate 3 returns to its original position, and then the seat of the cart and the lifting plate 3 cover the second trash can, and then the lifting plate 3 and the supporting assembly are controlled to move upward, and the diagonal support plate 11 of the supporting assembly contacts the outer walls of the two trash cans to lift the two trash cans, and finally the motor 7 is controlled to stop rotating, and the two trash cans can be transported to the designated location. The entire transport process basically does not require the cleaning staff to bend down to carry the trash cans.

[0032] If a smaller trash can is used, the width of the supporting assembly can be adjusted by simply opening the elastic handle 1304 of the elastic structure upwards to separate the locking block 1306 from the telescopic rod 10 .

[0033] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
