[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Embodiment 1

[0031] Please refer to the attached Figures 1-5 , an integrated vibration transmitter, comprising:

[0032] An outer shell 1, a circuit board 2, a wiring harness 3 and an end cap 4. A sensor 12 is placed inside the outer shell 1. The circuit board 2 is fixedly connected to the sensor 12 through a fixed column 10, and the circuit board 2 is electrically connected to the sensor 12. The end cap 4 is detachably connected to the outer shell 1, and a connector 40 is provided at the top of the end cap 4. One end of the wiring harness 3 is connected to the circuit board 2, and the other end passes through the end cap 4 and is connected to the connector 40. Epoxy resin 11 is poured into the outer shell 1;

[0033] By detecting the change in acceleration of the sensor 12 within the housing 1 as the detected object vibrates, the purpose of monitoring the vibration of the detected object is achieved. The use of the fixing post 10 enables the circuit board 2 to be initially fixed within the housing 1, and then the circuit board 2 is further fixed by pouring epoxy resin 11 into the housing 1. It should be noted that the pouring height of the epoxy resin 11 should not exceed the position of the circuit board 2. While fixing the circuit board 2, the use of epoxy resin 11 can also reduce the rigid feedback of vibration by avoiding the rigid contact between the circuit board 2 and the housing 1, thereby effectively protecting the circuit board 2. It should be noted that there are various fixing methods for the end cap 4 and the housing 1. For example, one method is to set matching threads on the end cap 4 and the housing 1 for detachable connection through the threads. Another method is to set a hollow cylinder within the housing 1. At the same time, a hole is opened at the top of the end cap, and then the end cap is fixed by threading a screw through the hole at the top of the end cap and connecting it to the hollow cylinder in a threaded manner. The third method is to open screw holes at corresponding positions on the side walls of the end cap 4 and the housing 1, and then fix them with screws. Three methods are listed here, but the specific fixing method is not limited to the above three methods.

[0034] Specifically, a convex block 41 integrally formed with the end cap 4 is provided. A display screen 410 fixedly connected to the convex block 41 is provided on the convex block 41. The connector 40 is fixedly connected to the side wall of the convex block 41. The wire harness 3 is respectively connected to the connector 40 and the display screen 410. Considering that in actual applications, there is a situation where it is necessary to record vibrations in real time, in order to facilitate recording, a convex block 41 and a display screen 410 are provided on the end cap 4 to facilitate the staff to record data in real time.

[0035] Embodiment Two

[0036] Please refer to the appendix Figures 6-7

[0037] Specifically, a protective plate 42 is provided on the end cap 4. The protective plate 42 contacts the side wall of the convex block 41 where the display screen 410 is provided, and the lower end of the protective plate 42 is elastically hinged to the top wall of the end cap 4. Considering that in actual applications, the environment where the vibration transmitter is located has a large amount of dust, in order to avoid the situation where dust adheres to the display screen 410 and makes it impossible to see the specific data clearly, an elastically hinged protective plate 42 is provided. When it is necessary to observe the data on the display screen 410, the protective plate 42 can be rotated. After observation, when the protective plate 42 is released, it can automatically return to its initial position to continue protecting the display screen 410.

[0038] Specifically, the end cover 4 includes an end cover body 43, at least two sliders 44, and a movable end cover 45. A chute 430 is provided on the side wall of the end cover body 43. The two sliders 44 are respectively fixedly connected to the concave side wall of the movable end cover 45 at symmetric positions, and the two sliders 44 are slidably connected in the chute 430. Considering that in practical applications, the environment where the vibration transmitter is located is narrow, resulting in the inconvenient observation of the position of the display screen 410. In order to facilitate the staff to observe the data on the display screen 410, the end cover 4 is connected in a sliding manner with the movable end cover 45 and the end cover body 43. Through the sliding connection of the slider 44 in the chute 430, the end cover body 43 can rotate freely, thereby achieving the purpose of changing the position of the display screen 410.

[0039] Embodiment III

[0040] Please refer to the appendix Figures 8-10

[0041] Specifically, a connecting bolt 13 is provided at the bottom of the housing 1. Considering the fixation of the transmitter, the connecting bolt 13 is provided at the bottom of the housing 1, and the transmitter is fixed by the connecting bolt 13 and the screw hole pre-set on the device.

[0042] Specifically, a base 5 is provided on the bottom wall of the housing 1. A connecting cavity 50 is provided at the upper end of the base 5, and at least two groups of mounting holes 500 are provided on the side wall of the connecting cavity 50. A central through hole 51 matching the connecting bolt 13 is provided at the middle position of the base 5. In order to further fix the housing 1, the base 5 is provided. The base 5 is arranged between the housing 1 and the device, and the contact area between the transmitter and the device is indirectly enlarged through the base 5, thereby achieving the purpose of the same-frequency vibration of the transmitter and the device. It should be noted that for different devices, the corresponding bases 5 are also different. For example, if the contact surface at the fixed position of the base 5 is a curved surface, a base 5 with a curved contact surface with the device should be used (as shown in the appendix Figure 10 shown). If the contact surface at the fixed position of the base 5 is a special-shaped surface, such as a toothed shape, a base 5 with a special-shaped surface as the base surface of the device should be selected. Since the structure of the base 5 is relatively simple, in practical applications, the corresponding base 5 can be completely customized according to its fixed position.

[0043] Specifically, the base 5 is provided with a locking assembly 6. The locking assembly 6 includes at least two groups of locking pins 60, at least two groups of springs 61 and an annular locking shell 62. The two groups of locking pins 60 pass through the two mounting holes 500. The two groups of springs 61 are located in the two mounting holes 5000, and both ends of the spring 61 are fixedly connected to the locking pin 60 and the side wall of the mounting hole 500 respectively. The annular locking shell 62 is threadedly connected to the upper end of the convex side wall of the base 5. Considering that after the connection between the base 5 and the outer wall of the housing 1, the connection between the base 5 and the housing 1 may be detached due to long-term vibration. To further strengthen the connection state between the base 5 and the housing 1, the locking pin 60 and the spring 61 are arranged in the mounting hole 500, and the annular locking shell 62 is threadedly connected to the inner wall of the connection cavity 50. By squeezing the locking pin 60 with the annular locking shell 62, the locking pin 60 is forced to contact the side wall of the housing 1 and form extrusion on the side wall of the housing 1, thereby achieving the purpose of fixing the position of the housing 1.

[0044] Specifically, the height of the annular locking shell 62 is greater than the distance from the mounting hole 500 to the top wall of the base 5. The setting that the height of the annular locking shell 62 is greater than the distance from the mounting hole 500 to the top wall of the connection base 50 is to ensure that the annular locking shell 62 can contact the locking pin 60 and form extrusion on the locking pin 60.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
