[0045] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0046] See also Figure 1 , Figure 3 and Figure 6 The utility model provides a laboratory suspension bridge, which is connected to the wall of the laboratory, including a shell 1, at least one rocker arm 2 and at least one clamping assembly 3. One end of the rocker arm 2 is rotatably connected to the shell 1, and the other end can rotate relative to the shell 1 around the rotation axis of the connection between it and the shell 1. The clamping assembly 3 includes a clamping member 31 and a driving member 32. The clamping member 31 is arranged relative to the rocker arm 2 and is slidably connected to the shell 1. The driving member 32 is connected to the clamping member 31 and the shell 1, and is used to drive the clamping member 31 to slide relative to the shell 1 close to or away from the rocker arm 2, so that the clamping member 31 is clamped with the rotated rocker arm 2.

[0047] In the present device, at least one rocker arm 2 is provided on the shell 1, wherein one end of the rocker arm 2 is rotatably connected to the shell 1, so that the other end of the rocker arm 2 can rotate relative to the shell 1 around the rotation axis of the connection between it and the shell 1, and the clamping member 31 is arranged relative to the rocker arm 2 and is slidably connected to the shell 1. Under the drive of the driving member 32, the clamping member 31 can slide closer to or away from the rocker arm 2 relative to the shell 1 and be clamped with the rocker arm 2, so as to limit the other end of the rocker arm 2 from rotating relative to the shell 1.

[0048] Compared with the prior art, by setting the clamping member 31 and the driving member 32 relative to the rocker arm 2, after the rocker arm 2 rotates relative to the shell 1, the driving member 32 can drive the clamping member 31 to slide close to the rocker arm 2 and clamp with the rocker arm 2, so that the rocker arm 2 cannot rotate relative to the shell 1, thereby avoiding accidental swing of the rocker arm 2. At the same time, the driving member 32 can drive the clamping member 31 to slide away from the rocker arm 2 and contact and clamp with it, so that the rocker arm 2 can rotate and unfold relative to the shell 1, which can solve the technical problem in the prior art that the rocker arm 2 is easily affected by gravity and swings accidentally after being rotated and stored in the groove without being fixed to the fixing seat, thereby causing safety hazards.

[0049] Furthermore, the shell 1 in the present device is the outer shell of the cantilever body, the interior of the outer shell of the cantilever body is hollow, and it is suspended on the inner wall of the laboratory, and air supply, power supply and water supply pipelines are respectively arranged inside. The rocker arm 2 is provided with power supply and water supply ports. The user can conveniently realize the power supply or water supply of the rocker arm to the electricity and water equipment by rotating the rocker arm 2. Here, at least one ventilation pipe 6 connected to the interior is also arranged at the bottom of the outer shell of the cantilever body, and the ventilation pipe 6 is a corrugated pipe with a telescopic function. The role of the suspension bridge in the laboratory here belongs to the conventional setting known to technicians in this field, and will not be elaborated here.

[0050] Furthermore, a hand grip is provided on the outer wall of the rocker arm 2, so that the user can hold and rotate the rocker arm 2 conveniently. At the same time, the rocker arm 2 unfolded after rotation can conveniently realize the function of extending the wiring, which will not be elaborated here.

[0051] like Figure 2 , Figure 4 and Figure 5 As shown, at least one groove is provided at the bottom of the shell 1, one end of the rocker arm 2 is rotatably connected to the inner wall of the groove, and the laboratory suspension bridge also includes a hinge 4, one end of the hinge 4 is hinged to the inner wall of the groove, and the other end is hinged to the rocker arm 2.

[0052] A hinge 4 is also provided between the rocker arm 2 and the housing 1 to improve the stability of the rocker arm 2 in rotation relative to the housing 1 .

[0053] As an implementation method, Figure 2 , Figure 4As shown, the hinged member 4 includes a first hinged rod 41, a second hinged rod 42 and a rotating portion 43, one end of the first hinged rod 41 is rotatably connected to the inner wall of the groove, one end of the second hinged rod 42 is rotatably connected to the rocker arm 2, and the other end of the second hinged rod 42 is rotatably connected to the other end of the first hinged rod 41 via the rotating portion 43.

[0054] The other end of the second hinged rod 42 is rotationally connected to the other end of the first hinged rod 41 via a rotating portion 43, and one end of the first hinged rod 41 is rotationally connected to the inner wall of the groove, and one end of the second hinged rod 42 is rotationally connected to the rocker arm 2, so that the rocker arm 2 can provide a stable supporting force during the rotation relative to the shell 1.

[0055] like Figures 3 to 6 As shown, the clamping member 31 includes a connecting block 311 and a clamping block 312 , at least one guide block 313 , and at least one rolling portion 314 .

[0056] The connecting block 311 is connected to the open end of the groove and is provided with a sliding groove relative to the rocker arm 2 . One end of the clamping block is slidably inserted in the sliding groove and the other end can abut against the rocker arm 2 .

[0057] The connecting block 311 is used to connect the clamping block 312 to the open end of the groove of the housing 1 .

[0058] As an implementation method, Figure 6 As shown, at least one guide slot is formed on the inner wall of the slot, and one end of the guide block 313 is connected to the clamping block 312 and the other end is slidably embedded in the guide slot.

[0059] The cooperation between the guide block 313 and the guide slot is used to connect and guide the sliding of the clamping block 312 relative to the slot.

[0060] As another implementation method, Figure 6 As shown, the guide block 313 is provided with a receiving groove relative to the inner wall of the guide slot, the receiving groove is hemispherical, and the rolling portion 314 is rotatably built into the receiving groove and abuts against the inner wall of the guide slot.

[0061] The rolling portion 314 is rotatably built into the receiving groove and abuts against the inner wall of the guide sliding groove, so as to reduce the sliding friction between the guide block 313 and the guide sliding groove.

[0062] Furthermore, the rolling part 314 in the present device is a steel ball or a stainless steel ball which is common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0063] like Figure 6As shown, a mounting groove is provided on the bottom inner wall of the slide groove, and the driving member 32 includes a permanent magnet 321, an electromagnet 322 and a coil 323. The permanent magnet 321 is built into the slide groove and connected to the clamping block 312. The electromagnet 322 is arranged relative to the permanent magnet 321 and connected to the inner wall of the mounting groove. The coil 323 is wound around the electromagnet 322 to generate a magnetic adsorption force that pushes the permanent magnet 321 and the clamping block 312 to slide close to or away from the electromagnet 322.

[0064] The electromagnetism characteristics generated by energizing the coil 323 enable the electromagnet 322 to generate a magnetic repulsive force opposite to the magnetism of the permanent magnet 321 , thereby causing the permanent magnet 321 and the clamping block 312 to slide away from the electromagnet 322 and clamp with the rocker arm 2 .

[0065] Furthermore, after the electromagnet 322 is powered off, the electromagnet characteristics disappear, and the magnetic adsorption force of the permanent magnet 321 causes the permanent magnet 321 and the clamping block 312 to slide close to the electromagnet 322 and release the clamping connection with the rocker arm 2, which will not be elaborated here.

[0066] Furthermore, the coil 323 in the present device is electrically connected to the controller, and the controller is a PLC controller that is common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0067] As another implementation method, Figure 1 , Figure 3 As shown, the device further comprises at least one connector 5, which is connected to the housing 1 and is used to connect the housing 1 to the wall of the laboratory.

[0068] Specifically, the number of connectors 5 in the device is two connectors 5 which are arranged at intervals on the top of the shell 1 and connected to the top wall of the laboratory.

[0069] As another implementation method, Figure 1 , Figure 3 As shown, there are two rocker arms 2 in the laboratory suspension bridge. The two rocker arms 2 are arranged opposite to each other and are both rotatably connected to the shell 1.

[0070] The two rocker arms 2 are arranged opposite to each other and can be folded close to each other or unfolded away from each other to meet the needs of multiple power and water consumption ends, which will not be elaborated here.

[0071] According to the specific working process of the utility model, at least one rocker arm 2 is arranged on the shell 1, wherein one end of the rocker arm 2 is rotatably connected to the shell 1, so that the other end of the rocker arm 2 can rotate relative to the shell 1 around the rotation axis of the connection between it and the shell 1, and the clamping member 31 is arranged relative to the rocker arm 2 and is slidably connected with the shell 1. Under the drive of the driving member 32, the clamping member 31 can slide close to or away from the rocker arm 2 relative to the shell 1 and be clamped with the rocker arm 2 to limit the other end of the rocker arm 2 from rotating relative to the shell 1. Compared with the prior art, by setting the clamping member 31 and the driving member 32 relative to the rocker arm 2, after the rocker arm 2 rotates relative to the shell 1, the driving member 32 can drive the clamping member 31 to slide close to the rocker arm 2 and be clamped with the rocker arm 2, so that the rocker arm 2 cannot rotate relative to the shell 1, thereby avoiding accidental swinging of the rocker arm 2. At the same time, the driving member 32 can drive the clamping member 31 to slide away from the rocker arm 2 and contact and clamp with it, so that the rocker arm 2 can rotate and unfold relative to the shell 1.

[0072] During use, when the user needs to unfold the rocker arm 2 and connect electricity or water to the power end or the water end, the control coil 323 is first powered off. At this time, the clamping block 312 releases the clamping connection with the rocker arm 2. Then the user moves the rocker arm 2 by hand, and can drive the rocker arm 2 to rotate relative to the shell 1 and unfold it. The unfolded rocker arm 2 can be conveniently connected to electricity or water.

[0073] Furthermore, when the rocker arm 2 needs to be stored, first disconnect the power end and the water end from the rocker arm 2, then manually move the rocker arm 2 to rotate relative to the shell 1, and store it in the groove after rotation, then control the coil 323 to be energized, and the magnetic repulsion force generated by the electromagnet 322 can push the permanent magnet 321 to slide relative to the slide groove and engage with the rocker arm 2, and finally the rocker arm 2 cannot rotate relative to the shell 1.

[0074] The device, through the above structure, can solve the technical problem in the prior art that the rocker arm 2 is easily affected by gravity and swings unexpectedly, thus causing safety hazards, because the rocker arm 2 is not fixed to the fixing seat after being rotated and stored in the groove.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
