[0030] In combination Figures 1 to 5 As shown in the drawings, the fixed type magnetic stand provided by the present application comprises a frame body 1, a spring telescopic rod 2, and a suction cup 3.

[0031] In combination Figures 1 to 5 As shown, the spring telescopic rod 2 is fixedly connected to the bottom surface of the frame body 1, and the spring telescopic rod 2 constitutes a support leg of the frame body 1 to support the frame body 1 placed on the desktop; the suction cup 3 is fixedly connected to the bottom surface of the frame body 1 downward, and the height of the suction cup 3 is not greater than the length of the spring telescopic rod 2; after the frame body 1 is pressed downward, the spring telescopic rod 2 is retracted, the suction cup 3 is adsorbed to the desktop, and the elastic force of the spring telescopic rod 2 and the adsorption force of the suction cup 3 jointly act to fix the frame body 1 on the desktop.

[0032] In this embodiment, the frame body 1 is supported in the normal state by the spring telescopic rod 2, lacks a fixing effect but is convenient for daily use; the spring telescopic rod 2 is retracted by pressing the frame body 1, so that the suction cup 3 can be adsorbed to the desktop, and the elastic force generated by the compression of the spring telescopic rod 2 causes the suction cup 3 to be in a pre-tightened state, at which time the fixing effect of the frame body 1 is more stable and reliable, and the two states can be freely switched to realize flexible and controllable fixing of the frame body 1.

[0033] The two states in this embodiment correspond to the normal state and the fixed state, respectively. In the normal state, the spring telescopic rod 2 completes the support of the frame body 1, and the frame body 1 can be moved at will; the suction cup 3 can be successfully adsorbed to the desktop by pressing the frame body 1, and the spring telescopic rod 2 is in a compressed state to generate an elastic force to lift the frame body 1 upward, thereby completing the switching from the normal state to the fixed state, at which time the adsorption of the suction cup 3 is in a pre-tightened state, and the adsorption effect is more stable; the state of the air valve 31 controlled by the connecting rod 32 can contact the adsorption state of the suction cup 3, and return to the normal state.

[0034] In some embodiments, in combination Figures 2 to 4 As shown, the frame body 1 is sequentially provided with a hole plate 11, a support column 12 and a bottom plate 13 from top to bottom, the support column 12 and the bottom plate 13 are respectively fixedly connected to the upper and lower ends of the support column 12, the bottom surface of the bottom plate 13 is fixedly connected to the spring telescopic rod 2 and the suction cup 3, the frame body 1 is provided with a magnet 14, the top end of the support column 12 is provided with a magnet positioning hole, the magnet positioning hole is close to the mounting hole on the hole plate 11, and the magnet 14 is assembled in the magnet positioning hole. The assembly mode of the magnet 14 assembled through the magnet positioning hole is beneficial to the replacement of the magnet 14 and does not affect the fixing effect of the magnet 14.

[0035] In some embodiments, in combination Figure 3 As shown, a through hole is formed in the side wall of the support column 12, the through hole transversely penetrates the magnet positioning hole, and the magnet 14 is exposed at the through hole after being assembled in the magnet positioning hole. The size of the through hole is smaller than that of the magnet 14, the through hole reduces the magnetic force hindering effect of the support column 12 on the magnet 14, and facilitates the magnetic force influence of the magnet 14 on the composition.

[0036] In some embodiments, in combination with Figure 2 , Figure 4 As shown in the figure, the mounting holes on the hole plate 11 are uniformly distributed in a straight line, the number and distribution of the magnet positioning holes are the same as the mounting holes, and each magnet positioning hole is equipped with a magnet 14. The linear distribution of the composition and the magnet 14 can effectively ensure the stability of the influence on each composition.

[0037] In some embodiments, in combination with Figure 2 , Figure 3 As shown in the figure, the frame body 1 is in the shape of an I-beam, and the mounting holes on the hole plate 11 are symmetrically distributed on both sides of the support column 12. This structure can make better use of the magnetic field generated by the magnet 14 and increase the working efficiency of the magnetic force frame as a whole.

[0038] In some embodiments, in combination with Figure 4 As shown in the figure, the suction disc 3 is provided with a ventilation valve 31, which communicates the inside and outside of the suction disc 3. The ventilation valve 31 is normally in a cut-off state to ensure that the suction disc 3 can normally adsorb when the frame body 1 is pressed down. By adjusting the state of the ventilation valve 31, the suction disc 3 can be quickly released from the fixed state.

[0039] In some embodiments, in combination with Figure 4 , Figure 5 As shown in the figure, the frame body 1 is fixedly connected with a baffle 15 on the bottom surface. The baffle 15 covers the spring telescopic rod 2 and the suction disc 3 along the maximum contour of the bottom surface of the frame body 1. The baffle 15 can effectively protect the spring telescopic rod 2 and the suction disc 3 and improve the aesthetic appearance.

[0040] In some embodiments, in combination with Figure 4 As shown in the figure, the control end of the ventilation valve 31 is integrally connected with a connecting rod 32, the other end of the connecting rod 32 penetrates the baffle 15, and the connecting rod 32 drives the ventilation valve 31. By means of the connecting rod 32, the state of the ventilation valve 31 can be controlled by passing through the baffle 15, and the switching of the fixed state is facilitated.

[0041] In some embodiments, in combination with Figure 5 As shown in the figure, the number of the suction disc 3 is one, and the suction disc 3 is located at the center of the bottom surface of the frame body 1. The spring telescopic rod 2 is uniformly distributed around the suction disc 3. One suction disc 3 can better control the adsorption state and improve the stability of the adsorption state. The uniformly distributed spring telescopic rod 2 can ensure the balance between the spring force of the spring telescopic rod 2 and the adsorption force of the suction disc 3 and improve the stability of the magnetic force frame when it is fixed.

[0042] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
