Specific implementation plan

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0023] The inventor of this solution found that in the prior art, trigger-type button control is difficult to input accurate operation signals for micro-control with precision requirements, and cannot input linearly changing operation signals. The extended operation rod of the rocker-type control is prone to accidental touches, and requires a large installation control and operation space. This embodiment provides the following solutions:

[0024] like Figure 1 to Figure 2 As shown, this embodiment provides a lifting control handle, including a handle body 1, a liftable handle grip 2 is arranged outside the handle body 1, and elastic components and liftable lifting floating components are arranged at both ends of the handle body 1, and the lifting floating components are connected to the handle grip 2. One end of the elastic component is connected to the handle body 1, and the other end of the elastic component is connected to the lifting floating component. An inductive sensor 3 is arranged inside the handle body 1, and one of the lifting floating components is connected to a metal sensing block 4 corresponding to the sensing end of the inductive sensor 3.

[0025] It should be noted that the lifting and floating parts at both ends of the handle body 1 are kept suspended in the middle position of the handle body 1 by the support force and tension of the elastic component when no force is applied. After the handle body 1 is installed and fixed, when the handle grip 2 is manually held and moved up and down, the lifting and moving of the handle grip 2 drives the lifting and floating parts to move up and down, so that the metal sensing block 4 also moves with the movement of the lifting and floating parts. The inductive sensor 3 senses the distance between the metal sensing block 4 and outputs sensing signals of different position distance levels. The signal differentiation accuracy is high, and the position distance difference at the micron level can be sensed. After receiving the signal, the lifting device presets the signals of different position distance levels as different moving directions and moving speeds, thereby realizing linear vertical movement control.

[0026] Specifically, the handle body 1 is a hollow tubular structure, such as a metal tube. The surface of the handle grip 2 is provided with an anti-slip groove 24, so as to increase the friction force so that the handle grip 2 is not easy to slip out of the hand. The two ends of the handle body 1 are respectively provided with an upper waist-shaped hole 11 and a lower waist-shaped hole 12. The top of the handle body 1 is provided with an upper lifting floating member 5 and an upper elastic member 6, and the bottom of the handle body 1 is provided with a lower lifting floating member 7 and a lower elastic member 8. The upper elastic member 6 and the lower elastic member 8 are both springs, and the upper lifting floating member 5 and the lower lifting floating member 7 are both latches. The upper lifting floating member 5 passes through the upper waist-shaped hole 11, and both ends of the upper lifting floating member 5 are connected to the handle grip 2. The lower lifting floating member 7 passes through the lower waist-shaped hole 12, and both ends of the lower lifting floating member 7 are connected to the inner side of the handle grip 2. The two ends of the handle grip 2 are respectively provided with an upper positioning hole and a lower positioning hole, and both ends of the upper lifting floating member 5 are placed in the upper positioning hole, and both ends of the lower lifting floating member 7 are placed in the lower positioning hole. One end of the upper elastic component 6 is connected to the top of the handle body 1, and the other end of the upper elastic component 6 is connected to the upper lifting floating member 5. The inductive sensor 3 is fixed to the top of the handle body 1 through the annular clamp 31 and is placed in the upper elastic component 6. The metal sensing block 4 is connected to the upper lifting floating member 5 and is placed in the upper elastic component 6. The top of the handle body 1 is connected to a signal wire holder 9 for deriving the sensing signal wire.

[0027] It can be understood that the upper elastic component 6 exerts a pulling force on the upper lifting floating component 5, and the lower elastic component 8 exerts a supporting force on the lower lifting floating component 7, so that the upper lifting floating component 5 and the lower lifting floating component 7 are suspended in the handle body 1 without being subjected to force. The upper lifting floating component 5 and the lower lifting floating component 7 can move freely up and down in the upper waist-shaped hole 11 and the lower waist-shaped hole 12 respectively, and at the same time, the maximum displacement of the upper lifting floating component 5 and the lower lifting floating component 7 can be limited, thereby improving safety. The upper lifting floating component 5 is a latch that forms a clearance fit with the upper positioning hole, and the lower lifting floating component 7 is a latch that forms a clearance fit with the lower positioning hole, thereby further increasing the precision of the lifting and lowering movement.

[0028] The two ends of the handle grip 2 are respectively connected with an upper handle end cover 21 and a lower handle end cover 22 . The upper handle end cover 21 is provided with a clamping groove corresponding to the upper positioning hole, and the lower handle end cover 22 is provided with a clamping groove corresponding to the lower positioning hole.

[0029] It should be noted that the upper handle end cover 21 and the lower handle end cover 22 are connected to the two ends of the handle grip 2 through threads. When the upper handle end cover 21 and the lower handle end cover 22 are connected to the two ends of the handle grip 2, the clamping grooves respectively correspond to the clamping of the two ends of the upper lifting floating member 5 and the lower lifting floating member 7, so that the handle grip 2, the upper handle end cover 21, the lower handle end cover 22, the upper lifting floating member 5 and the lower lifting floating member 7 form an integral fixed structure.

[0030] Furthermore, the upper handle end cover 21 and the lower handle end cover 22 are both provided with guide sleeves 23 for sleeved on the handle body 1. Both ends of the handle grip 2 are provided with external threads, and the upper handle end cover 21 and the lower handle end cover 22 are both provided with internal threads adapted to the external threads.

[0031] It is understandable that the guide sleeve 23 can make the upper handle end cover 21 and the lower handle end cover 22 respectively adapt to the axial position of the handle body 1, so that the upper handle end cover 21 and the lower handle end cover 22 can respectively rise and fall and slide better along the handle body 1.

[0032] Furthermore, the bottom of the handle body 1 is connected to the bottom bracket 13 through a thread, one end of the lower elastic component 8 is fitted with the bottom bracket 13, and the other end of the lower elastic component 8 is connected to the lower lifting floating member 7. It can be understood that the locking degree of the bottom bracket 13 can be adjusted through the cooperation of the thread, thereby adjusting the elastic preload force of the lower elastic component 8.

[0033] In the specific implementation, after the handle body 1 is installed and fixed, when the handle grip 2 is manually held and moved up and down, the lifting and moving of the handle grip 2 drives the upper lifting floating member 5 and the lower lifting floating member 7 to move up and down, and the upper lifting floating member 5 drives the metal sensing block 4 to move up and down to change position, and the inductive sensor 3 senses the distance between the metal sensing block 4 and outputs sensing signals of different position distance levels. The signal differentiation accuracy is high and can sense the position distance difference at the micron level. After receiving the signal, the lifting device presets the signals of different position distance levels as different moving directions and moving speeds, thereby realizing linear vertical movement control.

[0034] To sum up, the embodiments of the utility model provide a lifting control handle, which combines the handle and the grip into one. When operating the handle grip, high-precision nonlinear operation signal output is achieved through electric induction, and the distance detection accuracy is further improved through the lifting and floating structure formed by the pin and spring in the handle. The required installation space and operating space are extremely small, it conforms to ergonomics, the installation and fixing method is highly variable, and it can be applied to various usage conditions.
