Description

Technical Field

[0001] This utility model relates to the field of suction cup foot pad technology, and more specifically, to a suction cup foot pad that is easy to carry. Background Technology

[0002] Laboratory instruments typically require high operational stability. Some instruments generate significant vibrations during operation. To ensure stable placement on the workbench, instrument feet are often designed as suction cups, using the negative pressure created by compressing the feet to secure the instrument. However, when moving the instrument, the suction cups must be lifted beforehand or lifted with considerable force, which is laborious and inconvenient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a suction cup foot pad that is easy to transport.

[0004] The objective of this utility model is achieved through the following technical solution: A suction cup foot pad for easy transport includes a fixed base, a connecting base, and a suction cup stacked sequentially. The connecting base has an air inlet chamber, and the suction cup has a first air inlet channel communicating with the air inlet chamber. The fixed base is slidably connected to the connecting base, and the connecting base is provided with a sealing mechanism for sealing the gap between the fixed base and the connecting base. When the fixed base and the connecting base abut against each other, outside air cannot enter the suction cup sequentially through the air inlet chamber and the first air inlet channel. When the fixed base and the connecting base are separated, the sealing mechanism is released, and outside air can enter the suction cup sequentially through the air inlet chamber and the first air inlet channel.

[0005] Furthermore, in this utility model, a connecting post is provided at the end of the connecting seat near the fixed seat, and the air inlet chamber is disposed in the connecting post; a countersunk hole with a diameter larger than the diameter of the connecting post is opened at the end of the fixed seat near the connecting seat, and the connecting post is slidably connected to the countersunk hole; the sealing mechanism is disposed on the outer peripheral side of the connecting post.

[0006] Furthermore, in this utility model, the sealing mechanism is a sealing ring that is engaged on the outer periphery of the connecting post. When the end of the fixing seat near the connecting seat abuts against the end of the connecting seat away from the suction cup, the sealing ring seals the gap between the inner wall of the countersunk hole and the connecting post. When the inner wall of the countersunk hole separates from the sealing ring, outside air can enter the air intake chamber through the gap between the fixing seat and the connecting seat and the countersunk hole in sequence.

[0007] Furthermore, in this utility model, an annular groove is provided on the outer periphery of the connecting column, the central axis of the annular groove is collinear with the central axis of the connecting column, and the sealing ring is disposed in the annular groove.

[0008] Furthermore, in this utility model, a second air intake channel communicating with the air intake chamber is provided at one end of the connecting column near the countersunk hole. A first screw is provided in the second air intake channel, one end of the first screw is connected to the inner bottom wall of the countersunk hole, and the nut of the first screw is located in the air intake chamber. The diameter of the first screw is smaller than the diameter of the second air intake channel, and the diameter of the nut of the first screw is larger than the diameter of the second air intake channel. The first screw ensures that when the inner sidewall of the countersunk hole separates from the sealing ring, the fixing seat cannot separate from the connecting seat.

[0009] Furthermore, in this utility model, the suction cup is fixed to the connecting seat by the second screw, and the first air inlet is disposed on the second screw.

[0010] The beneficial effects of this utility model are: This invention provides a suction cup foot pad for easy handling. When moving or transferring an instrument, simply lift the instrument upwards; since the mounting base is fixed to the instrument, it will move upwards along with it. Once the mounting base detaches from the sealing ring, air enters the countersunk hole through the gap between the mounting base and the connecting seat, then enters the air intake chamber through the second air intake channel, and finally enters the suction cup through the first air intake channel. At this point, the internal and external air pressure of the suction cup is balanced, causing it to detach from the tabletop and move with the instrument. This process eliminates the need to lift the suction cup beforehand or use significant force to pull it upwards; only the small frictional force between the mounting base and the sealing ring needs to be overcome, utilizing atmospheric pressure to lift the suction cup, thus achieving labor-saving and convenient handling.

[0013] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Please see Figures 1-3 This utility model provides a technical solution: A suction cup foot pad for easy transport includes a fixed base 101 (connected to the instrument), a connecting base 201, and a suction cup 301 stacked sequentially. The connecting base 201 has an air inlet chamber 401, and the suction cup 301 has a first air inlet channel 501 communicating with the air inlet chamber 401. The fixed base 101 and the connecting base 201 are slidably connected. The connecting base 201 is provided with a sealing mechanism for sealing the gap between the fixed base 101 and the connecting base 201. When the fixed base 101 and the connecting base 201 are in contact, outside air cannot enter the suction cup 301 sequentially through the air inlet chamber 401 and the first air inlet channel 501. When the fixed base 101 and the connecting base 201 are separated, the sealing mechanism is released, and outside air can enter the suction cup 301 sequentially through the air inlet chamber 401 and the first air inlet channel 501.

[0015] Specifically, in order to achieve a sliding connection between the fixed seat 101 and the connecting seat 201, in this embodiment, a connecting post 601 is installed at the end of the connecting seat 201 near the fixed seat 101, and the air inlet chamber 401 is located inside the connecting post 601; a countersunk hole 701 with a diameter larger than the diameter of the connecting post 601 is opened at the end of the fixed seat 101 near the connecting seat 201, and the connecting post 601 is slidably connected to the countersunk hole 701; a sealing mechanism is provided on the outer peripheral side of the connecting post 601.

[0016] Specifically, refer to Figure 2 or Figure 3 In this embodiment, the sealing mechanism is a sealing ring 801 that is clamped on the outer periphery of the connecting post 601. When the end of the fixed seat 101 near the connecting seat 201 abuts against the end of the connecting seat 201 away from the suction cup 301, the sealing ring 801 seals the gap between the inner wall of the countersunk hole 701 and the connecting post 601. When the inner wall of the countersunk hole 701 separates from the sealing ring 801, the outside air can enter the air intake chamber 401 through the gap between the fixed seat 101 and the connecting seat 201 and the countersunk hole 701 in sequence.

[0017] Specifically, refer to Figure 2 or Figure 3To facilitate the installation of the sealing ring 801, an annular groove is provided on the outer periphery of the connecting post 601 in this embodiment. The central axis of the annular groove is collinear with the central axis of the connecting post 601, and the sealing ring 801 is installed in the annular groove.

[0018] Reference Figure 2 or Figure 3 When the fixed seat 101 separates from the connecting seat 201, outside air can enter the suction cup 301 through the gap between the fixed seat 101 and the connecting seat 201, the countersunk hole 701, the air inlet chamber 401, and the first air inlet channel 501 in sequence. At this time, in order to prevent the connecting seat 201 from separating from the fixed seat 101, in this embodiment, a second air inlet channel 901 communicating with the air inlet chamber 401 is specially opened at the end of the connecting post 601 near the countersunk hole 701. A first screw 100 is installed in the second air inlet channel 901. 1. One end of the first screw 1001 is connected to the inner bottom wall of the countersunk hole 701. The nut of the first screw 1001 is located inside the air intake chamber 401. The diameter of the first screw 1001 is smaller than the diameter of the second air intake 901, and the diameter of the nut of the first screw 1001 is larger than the diameter of the second air intake 901. The length of the first screw 1001 should satisfy the following: the first screw 1001 ensures that when the inner side wall of the countersunk hole 701 is separated from the sealing ring 801, the fixing seat 101 cannot be separated from the connecting seat 201.

[0019] In this embodiment, the suction cup 301 is fixed to the connecting seat 201 by the second screw 1101, and the first air intake 501 is disposed on the second screw 1101.

[0020] Working principle: from Figure 2 or Figure 3 From the perspective of the instrument, when it needs to be moved or transferred, lifting the instrument upwards will cause it to move upwards along with the fixed base 101, which is fixed to the instrument. After the fixed base 101 is separated from the sealing ring 801, air enters the countersunk hole 701 through the gap between the fixed base 101 and the connecting base 201, then enters the air intake chamber 401 through the second air intake duct 901, and finally enters the suction cup 301 through the first air intake duct 501. At this time, the internal and external air pressure of the suction cup 301 is balanced, thus detaching it from the table and moving with the instrument.

[0021] During this process, there is no need to lift the suction cup 301 in advance, or to use a large force to pull the suction cup 301 upward. It is only necessary to overcome the small friction between the fixed seat 101 and the sealing ring 801 and use atmospheric pressure to lift the suction cup 301, thus achieving the functions of saving effort and facilitating transportation.

[0022] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
