[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. The following text is only used to describe one or several specific implementations of the present invention and does not strictly limit the scope of protection specifically claimed by the present invention.
[0027] The anti-falling handwheel under vibration environment provided by the present invention is explained below with reference to the accompanying drawings.
[0028] like Figure 1-3 The utility model provides a handwheel that prevents it from falling off in a vibration environment, comprising: 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 handwheel 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 handwheel 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 provided 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 together.
[0040] Optionally, the hexagonal nut 5 is threadedly connected to the rod 1 .
[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 includes 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 handwheel 7;
[0046] Step 4: Align the handle 6, hand wheel 7 and the hole of the bushing 3 with the spring 4, and connect them together with the shaft 2;
[0047] Step 5: Expand both ends of shaft 2.
[0048] In step 1, the spring 4 must be installed on the handle 6 and the hand wheel 7 and in the positioning grooves of the handle 6 and the hand wheel 7.
[0049] In step 2, the pressure of the handle 6 on 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. 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: by installing the spring 4 on the bushing 3, the spring 4 is prevented from shaking and deforming, maintaining effective elastic force, and the handle 6, handwheel 7 and bushing 3 with the spring 4 are connected together through the shaft 2. After assembly, the ends of the shaft 2 are flared to prevent it from falling off, thereby producing a handwheel that prevents it from falling off in a vibration environment. When the handle on the handwheel is opened, the handwheel is fixed to the rod 1 with the hexagonal nut 5, and the handle is covered. The spring on the handle generates a certain pressure, causing the handle to cover the handwheel, leaving no space for the hexagonal nut to exit, and preventing the hexagonal nut from falling off the rod after the handwheel is subjected to vibration.
[0052] The present invention relates to a switch installed in an environment with strong vibrations, in which the handle on the handwheel is used to prevent the handwheel from falling off after the vibration, thereby meeting the safety requirements of use. The method comprises the following steps: opening the handle on the handwheel, fixing the handwheel on the rod through a hexagonal nut, covering the handle, and the spring on the handle forming 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 the rod after being vibrated. During disassembly and maintenance, the handle can be opened, the hexagonal nut can be unscrewed, and the handwheel can be removed, which is very convenient. The switch meets the safety requirements of installation and use in an environment with strong vibrations. 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 space to exit, the spring 4 is installed on the bushing 3, the handle 6 and the handwheel 7 and the bushing 3 with the spring 4 are connected together through the shaft 2, and the two ends of the shaft 2 are flared after assembly to prevent falling off.
[0053] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
