[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0025] Example 1: This example provides a lock knob to prevent accidental activation, such as... Figure 1 and Figure 4 As shown, this invention solves the problem that knobs, which are usually exposed, will rotate when impacted, thus altering their working state. It includes a mounting base 1, with a knob body 2 mounted in the center. A locking structure 3 is provided on one side of the knob body 2. The locking structure 3 includes a vertical plate 31, fixedly mounted on the top of the mounting base 1. A horizontal moving member 32 is provided on the vertical plate 31. A locking block 33 is fixedly mounted on the side of the horizontal moving member 32 near the knob body 2. Multiple locking grooves 34 are formed on the outer circumferential surface of the knob body 2. The locking structure 3 is used to lock the knob body 2, and the locking grooves 34 are used to engage with the locking block 33.

[0026] Combination Figure 1 and Figure 3In an embodiment of this utility model, the lateral moving member 32 includes two sets of fixing plates 321, which are respectively fixedly installed on the top and bottom of the vertical plate 31 near the knob body 2. A sliding plate 322 is slidably installed between the two sets of fixing plates 321. A first spring 323 is fixedly connected between the sliding plate 322 and the vertical plate 31. The side of the sliding plate 322 away from the first spring 323 is fixedly connected to the locking block 33. A moving rod 324 is fixedly connected to the middle part of the side of the sliding plate 322 away from the knob body 2. The end of the moving rod 324 away from the sliding plate 322 passes through the vertical plate 31 and is fixed with a handle 325. A limit structure 4 is provided at the top of the moving rod 324 for fixing the moving rod 324.

[0027] When the knob body 2 needs to be rotated, the limiting structure 4 releases the fixing effect on the moving rod 324. Then, the user pulls the handle 325 to the right with one hand. The handle 325 drives the sliding plate 322 to the right through the moving rod 324 and squeezes the first spring 323. As the sliding plate 322 moves, it drives the locking block 33 to the right until the locking block 33 separates from the locking groove 34, releasing the fixing effect of the locking block 33 on the knob body 2. At this time, the user can rotate the knob body 2 with the other hand. When the knob body 2 does not need to be rotated, the user releases the handle 325. Under the elastic force of the first spring 323, the sliding plate 322 returns to its original position and drives the locking block 33 to lock into the inside of the locking groove 34 again, thereby locking the knob body 2 and preventing the knob body 2 from being accidentally touched under the action of external force, which would affect the control of the photoelectric device.

[0028] Example 2: Reference Figure 1 and Figure 2 To further improve the stability of the locking block 33 and the locking groove 34 when they are engaged, the limiting structure 4 includes a longitudinal moving part 41, which is set on the vertical plate 31. A T-shaped limiting rod 42 is fixedly connected to the side of the longitudinal moving part 41 away from the fixed plate 321. A limiting hole 43 is opened at the top of the moving rod 324 for engaging with the T-shaped limiting rod 42.

[0029] Refer to the diagram Figure 1 and Figure 2 In an embodiment of this utility model, the longitudinal moving member 41 includes a reserved groove 411, which is opened on the side of the vertical plate 31 away from the knob body 2. A movable plate 412 is slidably installed inside the reserved groove 411. A second spring 413 is fixedly connected between the top of the movable plate 412 and the inner top wall of the reserved groove 411. A connecting rope 414 is fixedly connected to the middle of the top of the movable plate 412. A pull ring 415 is fixedly connected to the top of the connecting rope 414. The pull ring 415 is located at the top of the vertical plate 31.

[0030] When the movable rod 324 needs to be moved, the user pulls the ring 415. The ring 415 drives the movable plate 412 to slide inside the reserved groove 411 through the connecting rope 414 and squeezes the second spring 413. As the movable plate 412 moves, it drives the T-shaped limit rod 42 to move upward until the T-shaped limit rod 42 separates from the limit hole 43, releasing the fixing effect of the T-shaped limit rod 42 on the movable rod 324. At this time, the movable rod 324 can be pulled to move laterally. When the locking block 33 engages with the locking groove 34, the ring 415 is released. Under the elastic force of the second spring 413, the movable plate 412 resets and drives the T-shaped limit rod 42 to engage again in the limit hole 43, thereby fixing the lateral position of the movable rod 324 and improving the locking effect of the locking structure 3 on the knob body 2.

[0031] Combination Figure 2 and Figure 3 In this embodiment of the utility model, a fixing rod 311 is fixedly connected to the top side of the vertical plate 31 away from the pull ring 415. The pull ring 415 is sleeved on the outside of the fixing rod 311, thereby fixing the position of the T-shaped limiting rod 42 after it is separated from the limiting hole 43.

[0032] Example 3: Reference Figure 1 and Figure 3 To address the issue of hand slippage during the rotation of the knob body 2, a rubber sleeve 21 is fixedly fitted onto the top outer side of the knob body 2. When rotating the knob body 2, the user's hand comes into direct contact with the rubber sleeve 21, increasing the friction between the knob body 2 and the hand, thus minimizing the risk of hand slippage during rotation.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
