[0002] A high-frequency vibration collector is a device specifically used to collect high-frequency vibration signals.

[0003] For example, the utility model with publication number CN218673705U discloses a vibration data acquisition and analysis instrument with a protective structure. The protective structure has flexible contractility. When the vibration data acquisition and analysis instrument accidentally falls to the ground during operation, the first sheath and the second sheath are buffered and contracted by the spring arranged in the inner wall. The soft rubber arranged on the outer surface protects its parts from damage, and has a good protective effect.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] like Figures 1 to 5As shown, the utility model provides a high-frequency vibration collector for collecting vibration sensor signals, including a vibration collector body 1, a protection component 2 is installed on the outer surface of the vibration collector body 1, a limit component 3 is installed inside the protection component 2, and a movable component 4 is installed on one side of the limit component 3, the protection component 2 includes a connecting plate 21, an A telescopic spring 22, an extension column 23 and a protection plate 24, one end of the A telescopic spring 22 is fixedly connected to the inner wall of the connecting plate 21, and the other end of the A telescopic spring 22 is fixedly connected to one side of the extension column 23, the outer surface of the extension column 23 is slidably connected to the inner wall of the connecting plate 21, and the other side of the extension column 23 is fixedly connected to the side of the protection plate 24, the bottom surface of the vibration collector body 1 and the top surface of the connecting plate 21 are in contact with each other, a groove is provided inside the protection plate 24, and a plurality of groups of circular holes are provided on the other side of the protection plate 24.
[0023] The above scheme is adopted: through the setting of A telescopic spring 22, the extension column 23 and the protective plate 24 can be driven to move, so that the protective plate 24 can be adjusted according to the volume of the vibration collector body 1 of different signals, and by utilizing its own contractility, a certain inward contraction force is applied to the adjusted protective plate 24, so that the protective plate 24 has a certain protective effect on the vibration collector body 1.
[0024] like Figure 4 As shown, the limit assembly 3 includes a limit plate 31, a buffer pad 32, a B telescopic spring 33, a fixed block 35 and a limit column 36. The outer surface of the limit plate 31 is slidably connected to the inner wall of the protective plate 24, the outer surface of the buffer pad 32 is fixedly connected to the inside of the limit plate 31, and the bottom surface of the buffer pad 32 is in contact with the top surface of the vibration collector body 1, the top surface of the B telescopic spring 33 is fixedly connected to the bottom surface of the fixed block 35, and the bottom surface of the B telescopic spring 33 is fixedly connected to the inner wall of the groove, the top surface of the fixed block 35 is fixedly connected to the bottom surface of the limit plate 31, a circular groove is opened inside the limit plate 31, and a movable spring is fixedly installed inside the circular groove, one end of the movable spring is fixedly connected to one end of the limit column 36, the outer surface of the limit column 36 is slidably connected to the inside of the circular groove, and the limit column 36 is located inside the circular hole opened on the other side of the protective plate 24.
[0025] The above scheme is adopted: through the setting of the buffer pad 32, the top surface of the vibration collector body 1 is prevented from directly contacting the inner wall of the limit plate 31, and the damage to the top surface of the vibration collector body 1 caused by the limit plate 31 when it is fixed to the vibration collector body 1 for a long time is reduced. The position of the vibration collector body 1 can be fixed by the setting of the limit plate 31 to prevent the protection component 2 from falling off from the outer surface of the vibration collector body 1 during operation. The position of the limit plate 31 after adjustment can be fixed by the setting of the limit column 36 to prevent the limit plate 31 from loosening and causing the protection component 2 to fall off.
[0026] like Figure 3 to Figure 4 As shown, the movable component 4 includes a pushing plate 41, a pushing block 42, a telescopic cylinder 43, a C telescopic spring 44 and a limit block 45. The side of the pushing plate 41 close to the limit block 45 is fixedly connected to one end of the pushing block 42. The cross-sectional center point of the pushing block 42 and the cross-sectional center of the limit column 36 are located in the same horizontal plane, and the cross-sectional diameter of the pushing block 42 is smaller than the cross-sectional diameter of the circular hole. A groove A is provided on one side of the limit block 45. One end of the C telescopic spring 44 is fixedly connected to the inner wall of the groove A, and the other end of the C telescopic spring 44 is fixedly connected to the inner wall of the telescopic cylinder 43. One end of the telescopic cylinder 43 is fixedly connected to the inside of the groove A, and the other end is fixedly connected to the side of the pushing plate 41. The side of the limit block 45 away from the pushing plate 41 is fixedly connected to the side of the protective plate 24.
[0027] The above scheme is adopted: through the setting of the pushing plate 41 and the pushing block 42, the pushing plate 41 can be used to drive the pushing block 42 to move, so that the moved pushing block 42 enters the inside of the circular hole, and pushes the limiting column 36 located inside the circular hole toward the direction of the limiting plate 31, so that the limiting column 36 is freed from the restriction of the circular hole, thereby facilitating the adjustment of the position of the limiting plate 31, and the setting of the C telescopic spring 44 can restore the position of the pushing plate 41 and the pushing block 42 after being pushed to their original state.
[0028] The working principle and use process of the utility model are as follows: first, the staff uses the A telescopic spring 22 to pull the protection plate 24 outward, and drives the extension column 23 to extend continuously, puts the vibration collector body 1 on the top of the connecting plate 21, loosens the protection plate 24, and the protection plate 24 is driven by the A telescopic spring 22 to continuously shrink inward until it contacts one side of the vibration collector body 1, pushes the push plate 41, and brings the push block 42 into the inside of the circular hole through the push plate 41. At this time, the C telescopic spring 44 inside the movable cylinder is in an extruded state, so that the push block 42 contacts the limit column 36 and squeezes the limit column 36 out of the circular hole.
[0029] Then, the position of the limit plate 31 is moved downward so that the bottom surface of the buffer pad 32 contacts the top surface of the vibration collector body 1. At this time, the push plate 41 is released. After losing pressure, the C telescopic spring 44 will restore the push plate 41 and the push block 42 to their original positions due to its own inertia, so that the limit column 36 inside the limit plate 31 after adjustment can enter the inside of the circular hole again and fix the position of the limit plate 31.
