DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0041] Anti-static floor is a floor that can prevent the generation and accumulation of static electricity. It is used to protect electronic equipment and sensitive instruments. It is usually used in office buildings, computer rooms, and electronic factories. When it is necessary to lay cables or troubleshoot in these places, the anti-static floor needs to be removed.

[0042] In the related technology, a floor suction-lifting device is provided, which includes a supporting member, a suction cup member and a lifting member. The lifting member connects the suction cup member and the supporting member. A staff bends over and moves the lifting member to lift the suction cup member, thereby generating negative pressure between the suction cup member and the floor to adsorb the floor. A handle is provided on the supporting member. After the suction cup member adsorbs the floor, the staff bends over and lifts the handle to lift the floor off the ground.

[0043] However, it is more laborious for the staff to bend over and move the lifting member to lift the suction cup member, and it is also more laborious for the staff to bend over and lift the handle, which makes the efficiency of the whole process of the staff moving the floor out of the ground lower.

[0044] For the above technical issues, please see Figures 1 to 3 The embodiment of the present application provides a floor suction device, comprising: at least one suction cup assembly 100, the suction cup assembly 100 comprising a support member 110, a suction cup member 120 connected to the support member 110, and a sliding member 130 connecting the support member 110 and the suction cup member 120, the suction cup member 120 is used to contact with the floor, the sliding member 130 can slide relative to the support member 110, and the sliding of the sliding member 130 can drive the suction cup member 120 to move in a direction close to the support member 110, so that the suction cup member 120 adsorbs the floor; a pedal assembly 200, the pedal assembly 200 is rotatably connected to the sliding member 130, and the pedal assembly 200 abuts against the side of the support member 110 away from the suction cup member 120 The foot pedal assembly 200 is configured to rotate relative to the sliding member 130 under the action of an external force, so as to drive the sliding member 130 to slide relative to the supporting member 110; the balancing assembly 300, one end of the balancing assembly 300 is connected to the suction cup assembly 100, and the other end of the balancing assembly 300 is configured to contact the floor under the action of an external force, so as to maintain the position of the suction cup assembly 100; the lifting assembly 400, the lifting assembly 400 includes an extension rod 410 connected to the suction cup assembly 100 and a handle 420 connected to the extension rod 410, and the handle 420 is configured to drive the suction cup assembly 100 to lift in a direction away from the floor under the action of a holding force, so as to make the floor leave the ground.

[0045] The floor suction device provided in the embodiment of the present application is provided with a suction cup assembly 100, and the suction cup assembly 100 includes a support member 110, a suction cup member 120 connected to the support member 110, and a sliding member 130 connecting the support member 110 and the suction cup member 120. The support member 110 can support the suction cup member 120 and the sliding member 130. The sliding of the sliding member 130 relative to the support member 110 can drive the suction cup member 120 to move in a direction close to the support member 110, that is, the suction cup member 120 can move in a direction away from the floor. Negative pressure can be generated between the suction cup member 120 and the floor, and the suction cup member 120 can adsorb the floor.

[0046] By providing the pedal assembly 200, the pedal assembly 200 is rotatably connected to the sliding member 130. Under the action of external force, the pedal assembly 200 rotates relative to the sliding member 130 to drive the sliding member 130 to slide. The worker does not need to bend over to lift the suction cup member 120 so that the suction cup member 120 can adhere to the floor, which is labor-saving. It should be noted that the external force acting on the pedal assembly 200 can be a pedal force or a thrust force applied to the pedal assembly 200 by the worker through the intermediate connecting member.

[0047] By setting the balancing assembly 300, the balancing assembly 300 contacts the floor under the action of external force, and the position of the balancing assembly 300 can be maintained. The balancing assembly 300 is connected to the suction cup assembly 100, so the position of the suction cup assembly 100 can also be maintained, which can prevent the position of the suction cup assembly 100 from being unstable when the external force acts on the pedal assembly 200. It should be noted that the external force acting on the balancing assembly 300 can be a pedal force, or a pressure of a certain weight of a pressing member (such as iron or bricks, etc.) acting on the balancing assembly 300.

[0048] By setting a lifting assembly 400, the lifting assembly 400 includes an extension rod 410 connected to the suction cup assembly 100 and a handle 420 connected to the extension rod 410. The handle 420 can drive the suction cup assembly 100 to lift in a direction away from the floor under the action of the gripping force, and the floor can also be lifted in a direction away from the ground along with the suction cup assembly 100 under the action of the adsorption force, so that the floor is separated from the ground. In addition, the extension rod 410 has a certain length, and the handle 420 is connected to the suction cup assembly 100 through the extension rod 410. Compared with the prior art in which the handle 420 is directly connected to the suction cup assembly 100, the handle 420 of the embodiment of the present application has a certain height with the suction cup assembly 100, so that the staff can directly lift the suction cup assembly 100 with the help of this height without bending over, which is more labor-saving.

[0049] The preferred technical solution of the floor suction device of the embodiment of the present application is described below in conjunction with the accompanying drawings.

[0050] In some embodiments, see Figure 1 The handle 420 includes a load-bearing section 421 and at least two gripping sections 422 symmetrically connected to the periphery of the load-bearing section 421 , and the load-bearing section 421 is connected to the extension rod 410 .

[0051] In this embodiment, by providing at least two gripping sections 422, a gripping force is applied to each gripping section 422, making it easier to lift the floor to move the floor out of the ground. By symmetrically arranging at least two gripping sections 422, the force on the bearing section 421, the extension rod 410 and the suction cup assembly 100 is more uniform, which is more conducive to lifting the floor. Exemplarily, the number of gripping sections 422 is two, three or four. When the number of gripping sections 422 is two, it can be held by one or two staff members. When the number of gripping sections 422 is more than three, it can be held by more than two staff members to improve work efficiency.

[0052] It can be understood that the holding section 422 provided in this embodiment can be held by one staff member or multiple staff members. When multiple staff members work together, the difficulty of lifting the floor is reduced and the working efficiency is improved.

[0053] In some scenarios, the staff is located on the side of the suction cup assembly 100. When the staff uses the pedal force of one foot to act on the pedal assembly 200 and uses the pedal force of the other foot to act on the balance assembly 300, the staff can hold the handle 420 to maintain the stability of their posture. In this case, the length direction Y of the balance assembly 300 is facing the staff. If the handle 420 is also facing the staff, the handle 420 will interfere with the position of the staff, making it difficult for the staff to exert force, resulting in the floor being difficult to lift.

[0054] In order to solve the above technical problem, in other embodiments, the bearing section 421 is rotatably connected to the extension rod 410 , and the rotation axis of the bearing section 421 is parallel to the height direction Z of the balancing assembly 300 .

[0055] In this embodiment, by rotatably connecting the load-bearing section 421 to the extension rod 410, and making the rotation axis of the load-bearing section 421 parallel to the height direction Z of the balancing assembly 300, when viewed from the height direction Z of the balancing assembly 300, the load-bearing section 421 can be rotated so that an angle is formed between the load-bearing section 421 and the length direction Y of the balancing assembly 300. At this time, the load-bearing section 421 and the handle 420 provided thereon can be staggered away from the staff and will not interfere with the lifting operation of the staff.

[0056] In some specific embodiments, the load-bearing section 421 has a threaded hole (not shown), the hole wall of the threaded hole has an internal thread, the extension rod 410 has an external thread, the extension rod 410 is inserted into the threaded hole, and the internal thread and the external thread are matched and connected to make the load-bearing section 421 and the extension rod 410 rotatably connected.

[0057] In this embodiment, the external thread is located at the end of the extension rod 410 that is away from the suction cup assembly 100. Through the matching connection between the internal thread and the external thread, not only can the extension rod 410 support the load-bearing section 421, but also the load-bearing section 421 can rotate relative to the extension rod 410. The structure of the load-bearing section 421 with the internal thread and the extension rod 410 with the external thread is relatively simple and easy to manufacture.

[0058] Furthermore, a limiting portion (not shown) is provided on the extension rod 410 , and the bearing section 421 is located between the limiting portion and the suction cup assembly 100 . The limiting portion can limit the bearing section 421 to prevent the bearing section 421 from detaching from the extension rod 410 .

[0059] It is understandable that the embodiment of the present application does not limit the specific structure of the limiting portion, and can be adjusted according to actual needs. For example, the limiting portion can be protruded along the radial direction of the extension rod 410, or it can be a fastening screw set at the end of the extension rod 410, and tightening the screw can limit the bearing section 421.

[0060] In some other specific embodiments (not shown in the figure), the extension rod 410 has an annular groove, the bearing section 421 is sleeved in the annular groove, and the bearing section 421 can rotate along the annular groove relative to the extension rod 410. The bottom of the annular groove of the extension rod 410 has a plurality of evenly arranged first plug holes, and the bearing section 421 has a second plug hole. When the bearing section 421 rotates a preset angle relative to the extension rod 410, a latch is sequentially inserted into the second plug hole and the first plug hole to lock the rotation angle of the bearing section 421. It can be understood that the plurality of first plug holes correspond to a plurality of rotation angles respectively.

[0061] In some scenarios, such as near a wall or other obstacles, the wall or obstacles will hinder the handle 420, making it difficult to place the suction cup assembly 100 on the floor near the wall or other obstacles, thereby making it difficult for the floor suction device to pull out the floor.

[0062] In order to solve the above technical problem, in some other embodiments, the holding section 422 and the bearing section 421 are telescopically connected.

[0063] In this embodiment, by telescopically connecting the holding section 422 and the bearing section 421, when it is necessary to pull out the floor against the wall or close to other obstacles, the holding section 422 can be retracted to reduce the overall length of the holding section 422 and the bearing section 421. This allows the suction cup assembly 100 to be placed on the floor against the wall or close to other obstacles, and allows the staff to hold the holding section 422 within a certain operating space to move these floors out of the ground.

[0064] The embodiment of the present application does not specifically limit the telescopic connection structure between the gripping section 422 and the bearing section 421, and can be set according to specific needs. For example, the bearing section 421 has at least two telescopic rod structures, and at least two telescopic rod structures are connected to the gripping section 422. It should be noted that the telescopic rod structure is a structural design method already existing in the art, and will not be described in detail here.

[0065] In some other embodiments, the extension rod 410 is a telescopic rod.

[0066] In this embodiment, by using a telescopic rod as the extension rod 410, the length of the extension rod 410 can be increased or shortened to adapt to the heights of different workers, so that the workers can better apply force to the handle 420.

[0067] It should be noted that the telescopic rod is a structural design already known in the art and will not be described in detail herein.

[0068] In some embodiments, see Figure 1 and Figure 2 , the number of suction cup assemblies 100 is two; the lifting assembly 400 also includes a first connecting member 430, the first connecting member 430 connects the two suction cup assemblies 100, and the extension rod 410 is connected to the first connecting member 430.

[0069] The two suction cup assemblies 100 of this embodiment can be placed on one floor at the same time. The two suction cup assemblies 100 have a strong adsorption force on the floor, so that the lifting assembly 400 can more easily move the floor out of the ground. The two suction cup assemblies 100 of this embodiment can also be placed on two floors respectively, and each suction cup assembly 100 adsorbs each floor accordingly, so that the lifting assembly 400 can move two floors out of the ground at one time.

[0070] In other embodiments, see Figure 2 The balancing assembly 300 includes: two second connecting members 310, each second connecting member 310 is connected to each suction cup assembly 100; two third connecting members 320, each third connecting member 320 is connected to each second connecting member 310, and the third connecting member 320 is used to extend toward the floor; a first force-bearing member 330, the first force-bearing member 330 connects the two third connecting members 320, and the first force-bearing member 330 is configured to contact the floor under the action of an external force.

[0071] In this embodiment, by setting the first force-bearing member 330, the first force-bearing member 330 contacts the floor under the action of external force, and the floor can support the first force-bearing member 330 and maintain the position of the first force-bearing member 330; by setting two third connecting members 320, the two third connecting members 320 are connected to the first force-bearing member 330, and the first force-bearing member 330 can support the third connecting member 320 and maintain the position of the third connecting member 320; by setting two second connecting members 310, each second connecting member 310 is correspondingly connected to each suction cup assembly 100 and each third connecting member 320, the third connecting member 320 can support the second connecting member 310, the third connecting member 320 can support the second connecting member 310 and the suction cup assembly 100, and can maintain the position of the second connecting member 310 and the suction cup assembly 100, thereby preventing the suction cup assembly 100 from tipping over when the pedal assembly 200 is subjected to force.

[0072] In some other embodiments, see Figure 2 and Figure 3 The pedal assembly 200 includes: two fourth connecting members 210, each fourth connecting member 210 is rotatably connected to the sliding member 130 of each suction cup assembly 100; a second force-bearing member 220, the second force-bearing member 220 is connected to the two fourth connecting members 210, and the second force-bearing member 220 is configured to drive the fourth connecting member 210 to rotate relative to the sliding member 130 under the action of external force.

[0073] In this embodiment, the second force-bearing member 220 is arranged along the length direction Y of the balancing component 300, and the length direction Y of the balancing component 300 is perpendicular to the height direction Z of the balancing component 300. The second force-bearing member 220 connects two fourth connecting members 210. The second force-bearing member 220 has more force application points for external force application, which makes the rotation of the fourth connecting member 210 more convenient, and also makes it easier for the suction cup member 120 to adsorb to the floor.

[0074] For further information, see Figure 3 The fourth connecting member 210 includes a main body 211 and two protrusions 212 connected to the main body 211, a receiving groove 213 is formed between the two protrusions 212, and a part of the sliding member 130 is located in the receiving groove 213; the sliding member 130 has a first through hole 131, and the protrusion 212 has a second through hole 214, the pedal assembly 200 also includes a rotating shaft 230, and the rotating shaft 230 is inserted into the first through hole 131 and the second through holes 214 of the two protrusions 212; the protrusion 212 includes a first end face 215 away from the main body 211 and two second end faces 216 adjacent to the first end face 215, the distance between the hole axis of the second through hole 214 and the first end face 215 is a first distance, and the distance between the hole axis of the second through hole 214 and one of the second end faces 216 is a second distance, and the first distance is smaller than the second distance.

[0075] In some usage scenarios of this embodiment, please refer to Figure 3 , the state when the fourth connecting member 210 is parallel to the height direction Z of the balancing assembly 300 is the initial state, at which the first end surface 215 of the protruding portion 212 faces the supporting member 110; see Figure 2 , the pedal assembly 200 drives the fourth connecting member 210 to rotate so that the fourth connecting member 210 switches to a lifting state parallel to the width direction X of the balancing assembly 300, wherein the width direction X of the balancing assembly 300, the length direction Y of the balancing assembly 300 and the height direction Z of the balancing assembly 300 are perpendicular to each other, at this time, the second end surface 216 of the protrusion 212 faces the support member 110, and the position of the rotating shaft 230 in the lifting state is higher than that in the initial state. In the process of the fourth connecting member 210 switching from the initial state to the lifting state, the sliding member 130 is lifted upward along the height direction Z of the balancing assembly 300, so that the suction cup member 120 can adsorb the floor. It should be noted that the difference between the first distance and the second distance is the lifting height of the sliding member 130.

[0076] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
