Abstract
The utility model discloses a spring assistance lifting device which comprises a base seat and a lifting rod. One end of the lifting rod is connected with the base seat in a rotating mode. Spring front hooks are respectively arranged on the left side and the right side of the middle portion of the lifting rod. Spring back hanging holes are formed in the corresponding portions of the base seat. Springs are connected between the spring front hooks and the spring back hanging holes. A bolt is arranged below one end, close to the base seat, of the lifting rod, close to the base seat. A limiting blocking plate is arranged below the base seat. According to the spring assistance lifting device, ascending and descending of the lifting rod are achieved through the springs, fixing of an ascending position is achieved through the springs, fixing of a descending position is achieved through the bolt and the limiting blocking plate, and the spring assistance lifting device is simple in structure and practical.
Description
Technical field
Spring assist lowering or hoisting gear on a kind of floor cleaning machine of the utility model.
Background technology
Floor cleaning machine is applicable to residential quarter, hotel, factory, station, airport, dragging of hotels and other places and sweeps because drag relatively cleaner, save the advantage such as labour, the people that feel increasingly affectionate toward like.In the past floor cleaning machine mop lifting is adopted manually and is regulated, and does not support because there being thing, and obscission usually occurs fixedly the time, and impact is normally used.
The utility model content
The utility model technical issues that need to address are that manually adjusting is adopted in existing floor cleaning machine mop lifting, support because there being thing, and obscission usually occurs fixedly the time, and impact is normally used.
For solving the problems of the technologies described above, the utility model provides a kind of spring assist lowering or hoisting gear, comprise base and elevating lever, described elevating lever one end and described base are rotationally connected, be respectively equipped with the spring front hook in the left and right sides, described elevating lever centre position, hanging hole after described base relevant position has spring, spring are connected to behind described spring front hook and the spring between the hanging hole, be provided with bolt at described elevating lever near below base one end, below described base, be provided with postive stop baffle.Spring assist lowering or hoisting gear of the present utility model, by the rise and fall of spring realization elevating lever, the fixing of lifting position realized by spring itself, fixing by bolt and postive stop baffle realization of down position is simple in structure, practicality.
As another kind of scheme of the present utility model, also can be after described base relevant position be provided with the spring aft hook to substitute described spring hanging hole.
As further improvement of the utility model, above described base, be provided with the lifting position-limit baffle plate.Regulate the extreme position of rising by the lifting position-limit baffle plate.
Spring assist lowering or hoisting gear of the present utility model can be realized the lifting of mop very easily by manpower or frame for movement, the phenomenon that can not come off is convenient and practical.

Fig. 3 is the schematic diagram of the utility model elevating lever decline state;
Wherein, 1-base, 2-elevating lever, 3-spring, 4-spring front hook, hanging hole behind the 5-spring, 6-bolt, 7-postive stop baffle.
The specific embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, spring assist lowering or hoisting gear of the present utility model, comprise base 1 and elevating lever 2, described elevating lever 2 one ends and described base 1 are rotationally connected, be respectively equipped with spring front hook 4 in the left and right sides, described elevating lever 2 centre position, hanging hole 5 after described base 1 relevant position has spring, spring 3 is connected to behind described spring front hook 4 and the spring between the hanging hole 5, be provided with bolt 6 at described elevating lever 2 near below base 1 one ends, below described base 1, be provided with postive stop baffle 7, also can be after described base 1 relevant position be provided with the spring aft hook to substitute described spring hanging hole 5; Above described base 1, be provided with the lifting position-limit baffle plate, regulate the extreme position of rising by the lifting position-limit baffle plate.
Spring assist lowering or hoisting gear of the present utility model, mop is fixed on the front end of elevating lever, and elevating lever and base are rotationally connected, and make the elevating lever leading portion can realize lifting.3 of hanging holes placed on the same horizontal line after spring front hook, elevating lever revolved point, spring, and according to the length of spring, determined 3 relative distance.After by manpower or frame for movement elevating lever being risen, the spring front hook will be to top offset, and the three will form a triangle, after lifting process finishes, not to the elevating lever application of force, elevating lever also can keep the rise state under the effect of spring, can not be affected by gravity to cause elevating lever to descend.Certainly, according to the needs of actual conditions, can make corresponding position-limit mechanism at base, determine the extreme position that rises.In like manner, after elevating lever descended by manpower or frame for movement, the spring front hook will be to bottom offset, and the three will form a triangle, in case reach the extreme position of decline, elevating lever will be fixed under the effect of spring, thereby reach the fixedly effect of mop.The utility model is regulated the extreme position of decline by the postive stop baffle that is installed in bolt on the elevating lever and base below and stretches.
Spring assist lowering or hoisting gear of the present utility model, by the rise and fall of spring realization elevating lever, the fixing of lifting position realized by spring itself, fixing by bolt and postive stop baffle realization of down position is simple in structure, practicality.Spring assist lowering or hoisting gear of the present utility model can be realized the lifting of mop very easily by manpower or frame for movement, the phenomenon that can not come off is convenient and practical.
