[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. The following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the protection scope of the specific claims of the present invention.

[0027] The anti-falling hand wheel in a vibration environment provided by the present invention is explained below with reference to the accompanying drawings.

[0028] like Figure 1-3 The present invention provides a handwheel that prevents falling off in a vibration environment, including: a rod 1, a shaft 2, a bushing 3, a spring 4, a hexagonal nut 5, a handle 6, and a handwheel 7.

[0029] The hand wheel 7 is sleeved on the rod 1, the hexagonal nut 5 is sleeved on the rod 1, and the hexagonal nut 5 is arranged above the hand wheel 7;

[0030] The handle 6 and the hand wheel 7 are both rotatably connected to the shaft 2;

[0031] The handle 6 is arranged above the hand wheel 7 , and a groove is arranged below the handle 6 for accommodating the hexagonal nut 5 .

[0032] Optionally, the hand wheel 7 is petal-shaped.

[0033] Optionally, two lugs are provided on one side of the handle 6 and the hand wheel 7, and a bushing 3 is provided in each lug;

[0034] The shaft 2 is inserted into the bushing 3 .

[0035] Optionally, the lug of the handle 6 is arranged outside the lug of the hand wheel 7 .

[0036] Optionally, the handle 6 is tongue-shaped.

[0037] Optionally, it also includes: a spring 4;

[0038] A spring 4 is also sleeved on the shaft 2, and the spring 4 is a torsion spring;

[0039] Both ends of the spring 4 are arranged on the outside of the handle 6 and the hand wheel 7 for pressing the handle 6 and the hand wheel 7 .

[0040] Optionally, the hexagonal nut 5 and the rod 1 are threadedly connected.

[0041] Optionally, both ends of the shaft 2 are flared to prevent the shaft 2 from falling off.

[0042] Exemplarily, in one embodiment, a method for using an anti-drop handwheel in a vibration environment comprises the following steps:

[0043] Step 1: Put the spring 4 on the bushing 3;

[0044] Step 2: Place the handle 6 on the hand wheel 7;

[0045] Step 3: Install the spring 4 with the bushing 3 on the handle 6 and the hand wheel 7;

[0046] Step 4: Align the handle 6, the hand wheel 7 and the hole of the bushing 3 on which the spring 4 is put, and connect them together with the shaft 2;

[0047] Step 5: Expand both ends of shaft 2.

[0048] In step 1, the spring 4 is installed on the handle 6 and the hand wheel 7 and must be installed in the positioning grooves of the handle 6 and the hand wheel 7.

[0049] In step 2, the pressure of the handle 6 covering the hand wheel 7 can be achieved by adjusting the opening distance of the spring.

[0050] In step 5, both ends of the shaft 2 are expanded, and after expansion, it should be ensured that the hand wheel 7 and the handle 6 can move flexibly.

[0051] The working principle of the present invention is as follows: the present invention prevents the shaking and deformation of the spring 4 by installing the spring 4 on the bushing 3, maintains effective elastic force, and connects the handle 6, the handwheel 7 and the bushing 3 with the spring 4 through the shaft 2. After assembly, the two ends of the shaft 2 are expanded to prevent falling off, thereby making an anti-falling handwheel in a vibration environment. When the handle on the handwheel is opened, the handwheel is fixed to the rod 1 through the hexagonal nut 5, and the handle is covered. The spring on the handle forms a certain pressure, so that the handle covers the handwheel, leaving no space for the hexagonal nut to exit, thereby preventing the hexagonal nut from falling off from the rod after the handwheel is vibrated.

[0052] The present invention relates to a switch installed in an environment with strong vibration, which can prevent the handwheel from falling off after vibration through a handle on the handwheel, thereby meeting the safety requirements for use. The method comprises the following steps: opening the handle on the handwheel, fixing the handwheel on a rod through a hexagonal nut, covering the handle, and forming a certain pressure with a spring on the handle so that the handle covers the handwheel, and the hexagonal nut has no exit space, thereby preventing the hexagonal nut from falling off the rod after vibration. When disassembling and repairing, the handle can be opened, the hexagonal nut can be screwed off, and the handwheel can be removed, which is very convenient. The switch meets the safety requirements for installation and use in an environment with strong vibration. Since the pressure of the spring 4 presses the handle 6 onto the handwheel 7, it can be ensured that the hexagonal nut 5 connected to the rod 1 has no exit space, the spring 4 is installed on the bushing 3, the handle 6 and the handwheel 7 and the bushing 3 on which the spring 4 is sleeved are connected together through the shaft 2, and the two ends of the shaft 2 are expanded after assembly to prevent falling off.

[0053] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
