The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1-4 , which is the first embodiment of the present utility model. This embodiment provides a quick-installation mechanism, including a fixed cylinder 100 for supporting the quick-installation mechanism; a quick-installation component 200, which includes a fixing member 201 disposed inside the fixed cylinder 100, a pressing component 202 disposed inside the fixing member 201, a locking component 203 disposed below the pressing component 202, and a spring-back component 204 disposed below the locking component 203; a limiting component 300, which includes a displacement component 301 disposed on both sides of the inner wall of the fixed cylinder 100, and a transmission component 302 disposed on one side of the pressing component 202; wherein, the displacement component 301 is connected to the transmission component 302;

[0032] The fixing member 201 is disposed inside the fixed cylinder 100, the pressing component 202 is disposed above the fixed cylinder 100, both the locking component 203 and the spring-back component 204 are disposed below the fixed cylinder 100. There are two displacement components 301 and two transmission components 302. The two transmission components 302 are respectively disposed on both sides of the displacement cylinder 201b, and the two displacement components 301 are respectively connected to the two transmission components 302. Through the cooperation of the pressing component 202, the locking component 203, the transmission component 302, and the displacement component 301, an object can be stably installed inside the fixed cylinder 100. Then, through the design of the spring-back component 204, when the pressing component 202 is driven again, the object can be ejected from the fixed cylinder 100, facilitating the taking out of the object.

[0033] Further, the fixing member 201 includes an annular cylinder 201a disposed below the fixing cylinder 100, and a displacement cylinder 201b disposed inside the annular cylinder 201a; wherein, the pressing assembly 202 is slidably disposed inside the displacement cylinder 201b, the displacement cylinder 201b is slidably disposed inside the annular cylinder 201a, the annular cylinder 201a is designed with openings at both ends, the pressing assembly 202 is slidably disposed at the upper end of the annular cylinder 201a, and the rebounding assembly 204 is slidably disposed at the lower end of the annular cylinder 201a.

[0034] Further, the pressing assembly 202 includes a placement cylinder 202a disposed inside the displacement cylinder 201b, a displacement column 202b disposed below the placement cylinder 202a, a connecting groove column 202c disposed at one end of the displacement column 202b, and a first spring 202d disposed at one end of the connecting groove column 202c. The placement cylinder 202a is used for placing objects and is fixedly connected to the displacement column 202b by a fixed rod. The displacement column 202b is fixedly connected to the upper end of the connecting groove column 202c. An arc-shaped groove is formed at the lower end of the connecting groove column 202c for cooperating with the locking assembly 203. The lower end of the connecting groove column 202c is fixedly connected to one end of the first spring 202d. When the placement cylinder 202a is pressed down, the displacement column 202b and the connecting groove column 202c will be driven to move downward, thereby compressing the first spring 202d, and at the same time driving the locking assembly 203 to lock. When the placement cylinder 202a is pressed down again, when the connecting groove column 202c cooperates with the locking assembly 203, the locking assembly 203 is unlocked. Through the design of the rebounding assembly 204, the object can be taken out conveniently.

[0035] Further, the locking assembly 203 includes a displacement frame 203a disposed inside the displacement cylinder 201b, a spring piece 203b disposed at one end of the displacement frame 203a, and a card slot 203c disposed outside the annular cylinder 201a; wherein, the displacement frame 203a is slidably disposed inside the displacement cylinder 201b, the card slot 203c cooperates with the spring piece 203b, the displacement frame 203a can only move horizontally due to the limitation of the displacement cylinder 201b, and one end of the displacement cylinder 201b is fixedly connected to the spring piece 203b. When the placement cylinder 202a is pressed down, the displacement column 202b and the connecting groove column 202c will be driven to move downward, thereby compressing the first spring 202d. At this time, the spring piece 203b moves downward and thus enters the card slot 203c to form a lock. When the placement cylinder 202a is pressed down again, the connecting groove column 202c will contact the displacement frame 203a, thereby driving the displacement frame 203a to slide to one side, thereby driving the spring piece 203b away from the card slot 203c. Through the design of the rebounding assembly 204, the pressing assembly 202 rebounds, making it convenient to take out the object.

[0036] Further, the resilient component 204 includes a thrust post 204a disposed at the lower end of the displacement cylinder 201b and a second spring 204b disposed outside the thrust post 204a. Among them, the first spring 202d is fixedly connected to the upper end of the thrust post 204a, one end of the second spring 204b is fixedly connected to the lower end of the thrust post 204a, and the other end of the second spring 204b is fixedly connected to the lower end of the annular cylinder 201a. When the first spring 202d is in a compressed state, it will squeeze the thrust post 204a, so that the second spring 204b is also in a compressed state. When unlocked, the two springs release elastic potential energy at the same time, so that the placement cylinder 202a moves upward.

[0037] Further, the displacement assembly 301 includes a slide rail 301a disposed on the inner wall of the fixed cylinder 100, a slider 301b disposed inside the slide rail 301a, and a pressing plate 301c disposed at one end of the slider 301b. When the displacement post 202b is pressed downward, it drives the slider 301b to translate toward the center through the transmission assembly 302, so as to press the object through the pressing plate 301c.

[0038] Further, the transmission assembly 302 includes a chute 302a disposed inside the slider 301b, a connecting rod 302b disposed on one side of the displacement post 202b, and a connecting seat 302c disposed at one end of the connecting rod 302b. Among them, one end of the connecting seat 302c is slidably disposed in the chute 302a. The connecting rod 302b is arranged as an L-shaped rod. One end of the connecting rod 302b is fixedly connected to the displacement post 202b, and the other end is fixedly connected to the connecting seat 302c. The chute 302a is arranged as an inclined chute. The connecting seat 302c slides relative to the chute 302a, so that the slider 301b moves toward the center when the connecting rod 302b moves downward.

[0039] Operation process: When the placement cylinder 202a is pressed downward, it will drive the displacement post 202b and the connecting groove post 202c to move downward, thereby compressing the first spring 202d. At this time, the elastic piece 203b moves downward and enters the card slot 203c to form a lock. At this time, the displacement post 202b drives the connecting rod 302b to move downward, thereby driving the slider 301b to move toward the center, and then driving the pressing plate 301c to move toward the center;

[0040] When the placement cylinder 202a is pressed downward again, the connecting groove post 202c will contact the displacement frame 203a, thereby driving the displacement frame 203a to slide to one side, driving the elastic piece 203b away from the card slot 203c. The two springs release elastic potential energy at the same time, so that the placement cylinder 202a moves upward. At this time, the displacement cylinder 201b drives the connecting rod 302b to rise, thereby driving the slider 301b to slide to the side away from the center of the circle, driving the pressing plate 301c to move in the same direction as the slider 301b, so that the object can pop out for easy taking.

[0041] Example 2

[0042] Reference Figures 1-5 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a sensor fixing device, including an installation component 400, which includes a fixing plate 401 provided below the fixing cylinder 100, fixing bolts 402 provided at the four corners of the fixing plate 401, and a rotating component 403 provided inside the fixing plate 401. The fixing plate 401 is fixed inside the wind power fan blade through the fixing bolts 402, and then the quick-installing component 200 is installed above the fixing plate 401 through the rotating component 403.

[0043] Specifically, the rotating component 403 includes a slot 403a provided inside the fixing plate 401, an internal thread 403b provided inside the slot 403a, an annular plate 403c provided below the fixing cylinder 100, and an external thread 403d provided on the outer side of the annular plate 403c. The thickness of the slot 403a is the same as the thickness of the annular plate 403c, and the internal thread 403b is matched with the external thread 403d. Through the design of the internal thread 403b and the external thread 403d, stable installation can be achieved by screwing, and the operation is simple.

[0044] The rest of the structure is the same as that of Embodiment 1.

[0045] Example 3

[0046] Reference Figures 1-6 , which is the third embodiment of the present utility model. Different from the previous embodiment: A sensor body 500 is arranged inside the placement cylinder 202a. The sensor uses an optical fiber sensor. The optical fiber sensor belongs to a passive sensor and is one of the main sensor technologies developed in the 21st century. Compared with electrical sensors, optical fiber sensors generally have the characteristics of intrinsic safety, being free from electromagnetic interference, having no lightning strike hazards, and no risk of explosion and fire. At the same time, since the optical fiber sensor is a passive component and its core material is made of silica, it has high reliability in long-term use, a long service life, and strong adaptability to harsh environments such as high salt spray and corrosion. The signal transmission of the optical fiber sensor all uses optical cables, with strong multiplexing ability and simple networking. The use of optical fiber sensors also promotes the transformation of various industries from "detection" to "monitoring". It is made using the Fiber Bragg Grating (FBG) principle, and the system uses the optical fiber wavelength demodulation principle to complete the measurement: When the external change is transmitted to the sensor through the structure, the wavelength of the fiber grating of the sensor will drift, and the amount of drift is proportional to the magnitude of the physical quantity to be measured (such as load or temperature, etc.). By analyzing the optical wavelengths carrying these signals, the measurement of load, temperature, etc. can be completed.
