Technical Field

[0001] The utility model relates to the technical field of handheld suction cup tools, in particular to a suction cup device used for an electrostatic floor. Background Art

[0002] When working in a machine room, the static floor is often moved and restored. The floor suction cups on the market are all small hand-held suction cups. The use of the suction cups requires the operator to bend over or squat to operate the suction cups, which is inconvenient. Therefore, a suction cup device that is easy to use on site is designed.

[0003] After searching, Chinese patent document CN105731237A, published (announcement) date: 2016.07.06, discloses a multifunctional electrostatic floor suction cup for a computer room, including a vertical pipe, a horizontal pipe is arranged at the bottom end of the vertical pipe, a suction cup bracket is arranged at the bottom end of the horizontal pipe, a suction cup is arranged at the bottom end of the suction cup bracket, a horizontal bar is arranged in the horizontal pipe, the horizontal bar is slidably connected to the horizontal pipe, and transmission rods corresponding in number and position to the suction cups are arranged on the horizontal bar, a metal disk is arranged at one end of the transmission rod away from the horizontal bar, the metal disk is connected to the suction cup, an operating rod is arranged on the side of the horizontal bar away from the suction cup, and the multifunctional electrostatic floor suction cup also includes a limiting device for fixing the operating rod. Its characteristic is that the suction cup and the riser are used in conjunction with each other, and the floor can be lifted at any time. There is no need to use a crowbar or a screwdriver for prying, and the staff does not need to bend over to work. The floor movement work can be completed conveniently and quickly, saving manpower and time, improving labor efficiency, and reducing damage to the floor. Its disadvantage is that the edge of the suction cup is connected to the suction cup bracket, and the inside of the suction cup is also connected to the metal plate under the transmission rod. The suction cup will be folded repeatedly when in use. At present, the suction cup is generally made of rubber. The suction cup will be fatigued and damaged due to repeated folding, making the suction cup of the device easy to be damaged and having poor durability. Utility Model Content

[0029] See also Figure 1-3 A suction cup device for an electrostatic floor comprises an adsorption block 10, a sealing ring 20, a piston 30, a fixed handle 40 and an operating handle 50. The lower edge of the adsorption block 10 is sealed with a sealing ring 20, the sealing ring 20 extends downward from the adsorption block 10, the upper side of the adsorption block 10 is installed with a door-shaped fixed handle 40, the adsorption block 10 is longitudinally provided with at least one through hole 11, the piston 30 is slidably and sealedly installed in the through hole 11, the operating handle 50 is connected to the piston 30, and the operating handle 50 is located in the fixed handle 40. The suction cup device adsorbs the floor by cooperating with the adsorption block 10 and the piston 30, and there is no folding of the suction cup, so that the durability of the utility model is better.

[0030] Specifically, the sealing ring 20 is a flexible rubber ring, and the sealing ring 20 can be bonded to the bottom of the adsorption block 10 by glue.

[0031] When in use, first wipe the static floor clean, then place the suction cup device on the floor, and the sealing ring 20 contacts the static floor to form a seal. When operating, one hand holds the top of the fixed handle 40, and the fingers pull the operating handle 50 upward, so that the piston 30 moves upward. When the piston 30 moves upward, negative pressure is formed in the sealing ring 20, so that the adsorption block 10 is adsorbed on the floor, and then the suction cup device is lifted to lift the floor.

[0032] See also Figure 3The lower edge of the adsorption block 10 is provided with an annular groove 12, and the sealing ring 20 is installed in the annular groove 12, and the sealing ring 20 is sealed with the annular groove 12. The annular groove 12 is provided to facilitate the positioning of the sealing ring 20 and make the sealing effect between the sealing ring 20 and the adsorption block 10 more stable.

[0033] In one solution, a through hole 11 is longitudinally provided on the adsorption block 10, and the operating handle 50 includes a longitudinal rod 51 and a transverse rod 52, wherein the lower end of the longitudinal rod 51 is connected to the piston 30, and the upper end is connected to the transverse rod 52. In this solution, the operating handle 50 is T-shaped.

[0034] In another embodiment, see Figure 2 , 3 The adsorption block 10 is longitudinally provided with two through holes 11, and the operating handle 50 includes two longitudinal rods 51 and a transverse rod 52. The lower ends of the two longitudinal rods 51 are respectively connected to the two pistons 30, and the upper ends are connected to the transverse rod 52. In this scheme, the operating handle 50 is a door-shaped structure.

[0035] See also Figure 1 A crossbeam 41 is provided in the middle of the fixed handle 40, and the longitudinal rod 51 moves through the hole on the crossbeam 41. The longitudinal rod 51 is guided by the crossbeam 41 so that the longitudinal rod 51 always moves up and down in a directional manner. In this way, the piston 30 will not be blocked due to the tilting of the longitudinal rod 51.

[0036] Furthermore, the longitudinal rod 51 is provided with a lower limit plate 53 at the lower side of the cross beam 41, and an upper limit plate 54 at the upper side of the cross beam 41. The lower limit plate 53 and the upper limit plate 54 limit the travel of the longitudinal rod 51 to prevent the piston 30 from falling down or being pulled out from above.

[0037] Furthermore, a spring 55 is installed on the longitudinal rod 51 between the lower limit plate 53 and the cross beam 41. Under the action of the spring 55, the piston 30 can automatically reset after the operating handle 50 is released. It should be noted that the upper limit position of the piston 30 can also be limited by controlling the distance between the transverse rod 52 and the fixed handle 40. The function of the lower limit plate 53 at this time is to install the spring 55.

[0038] Specifically, in this embodiment, see Figure 3 The piston 30 includes a plug body 31 and a sealing ring 32. The plug body 31 is provided with an annular groove, and the sealing ring 32 is installed in the annular groove.

[0039] In addition to the above structure, the piston 30 may also adopt a piston structure similar to a syringe or a cylinder.

[0040] See also Figure 3The longitudinal rod 51 is screwed and fixed with the piston 30, which facilitates the connection between the longitudinal rod 51 and the piston 30. Further, after the longitudinal rod 51 is screwed and fixed with the piston 30, a locking nut 57 is screwed on the longitudinal rod 51 to prevent the piston 30 from loosening during use.

[0041] See also Figure 3 The lower end of the fixed handle 40 is inserted and installed in the adsorption block 10, and the adsorption block 10 is screwed with a limit screw 13 to fix the fixed handle 40 to the adsorption block 10, so as to facilitate the installation and connection between the fixed handle 40 and the adsorption block 10. Furthermore, a limit slot 42 is provided at one end of the fixed handle 40 inserted into the adsorption block 10, and the end of the limit screw 13 extends into the limit slot 42, so as to better prevent loosening.

[0042] The working principle or action process of the utility model is as follows:

[0043] When in use, first wipe the electrostatic floor clean, hold the top of the fixed handle 40, place the suction cup device on the floor, and the sealing ring 20 contacts the electrostatic floor to form a seal.

[0044] Afterwards, one hand holds the top of the fixed handle 40 and the fingers pull the operating handle 50 upward, so that the piston 30 moves upward. When the piston 30 moves upward, negative pressure is formed in the sealing ring 20, so that the adsorption block 10 is adsorbed on the floor, and then the suction cup device is lifted up to lift the floor.
