Automatic-switching broom with stretching function

Abstract

This invention discloses an automatic-switching broom with the stretching function. The broom comprises a fixing plate, wherein one end side of the fixing plate is connected with a left gear and a right gear through a fixing shaft, the left gear and the right gear are meshed with each other, and a left supporting frame and a right supporting frame are fixedly connected to the left gear and the right gear respectively; the upper end of the right supporting frame and / or the bottom of the right gear are / is fixedly connected with one end of a reset spring, and the other end of the reset spring is fixedly connected with the fixing plate; a through hole located in the fixing plate is formed in the upper end of the left supporting frame and connected with a locking block, and the locking block can move up and down in the direction of the central axis of the through hole; a locking hole corresponding to the locking block is formed in the left supporting frame; a cleaning plate is detachably connected to at least one of the bottom of the fixing plate and the bottoms of the supporting frames; under the action of the reset spring, the automatic-switching broom can be automatically switched from the state of the sweeping function to the pushing function when in the state of sweeping.

Description

technical field [0001] The invention relates to a broom, in particular to a broom with automatic switching between stretching and stretching functions. Background technique [0002] At present, the way of manual cleaning of garbage is still more traditional big brooms, which are made by manual tying, which have many shortcomings. One is that the efficiency of manual cleaning is low and the cost of labor is high; the other is The 2nd, waste resource, because the service life of traditional big broom is shorter, about 15 days just must replace, cause huge waste. [0003] The technical solution in the prior art, its patent name is: cleaning vehicle, patent number: 03241275.4, authorized announcement number: CN 2609968Y; it combines the cleaning device with the car body to realize the power conversion of the car body forward into the cleaning device to advance and Swing power; through the analysis of its manual, it can be seen that: 1.

Problems solved by technology

[0002] At present, the way of manual cleaning of garbage is still more traditional big brooms, which are made by manual tying, which have many shortcomings. One is that the efficiency of manual cleaning is low and the cost of labor is high; the other is The second is a waste of resources. Due to the short service life of the traditional broom, it must be replaced in about 15 days, resulting in huge waste

[0003] The technical solution in the prior art, its patent name is: cleaning vehicle, patent number: 03241275.4, authorized announcement number: CN 2609968Y; it combines the cleaning device with the car body to realize the power conversion of the car body forward into the cleaning device to advance and Swing power; through the analysis of its manual, it can be seen that: 1. The broom of the sweeper has a small swing range, which cannot effectively clean up the garbage on both sides, and the garbage is easy to slide through the brooms on both sides; 2. The swing mechanism of the sweeper It is the crank that drives the connecting rod, and then the left end of the broomstick body slides along the groove of the track. It will seriously affect or even block the swing of the broomstick

3. The structure of the sweeper is too complicated, easy to damage, and difficult to maintain

[0004] The technical solution in the prior art, the multifunctional cleaning device of shoveling, pushing, sweeping and brushing, its patent number is 201110240309.4, the authorized announcement number CN 102304902 B, and a stretching magic sweeper, its patent number is 201210040151.0, the authorized announcement number It is CN 102535375 B, which uses the deformation of the quadrilateral to realize the switching of the functions of shoveling, pushing, sweeping, and brushing; through the analysis of its instructions, it can be known that although it can effectively clean up the garbage on the road, it also has certain disadvantages: 1. Volume Large, not suitable for home use; 2. Complex structure and poor stability; 3. When switching to the push function, the cleaning area is small, and there are no baffles to control the garbage on the left and right sides, and the garbage is easy to slide out from both sides
