DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0020] This utility model embodiment provides a vibration-resistant electronic compass structure, such as Figures 1-5 As shown, the device includes an electronic compass body 1 and four sets of vibration damping components 2 installed at the four corners of the electronic compass body 1. Each of the four corners of the electronic compass body 1 has a mounting hole 11. Each set of vibration damping components 2 includes an outer sleeve 21 located inside the corresponding mounting hole 11. The outer sleeve 21 is a hollow cylindrical body with openings at both ends. A mounting sleeve 22 is coaxially mounted inside the outer sleeve 21. The mounting sleeve 22 is also a hollow cylindrical body with openings at both ends. The outer wall of the mounting sleeve 22 is connected to the inner wall of the outer sleeve 21 by several transverse elastic members 23. The two ends of the mounting sleeve 22 are connected to the electronic compass body 1 by longitudinal elastic members 24. During installation, the mounting sleeves 22 on the four sets of vibration damping components 2 are bolted to the device. The transverse elastic members 23 and longitudinal elastic members 24 absorb the transverse and longitudinal vibrations of the device during operation, resulting in good vibration damping and preventing damage to the components of the electronic compass body 1 due to vibration, thus extending its service life.

[0021] In this embodiment, the transverse elastic element 23 is a first spring. When the transverse elastic element 23 is the first spring, the inner wall of the outer sleeve 21 is provided with a first fixing post 211, which is integrally formed with the outer sleeve 21. The outer wall of the mounting sleeve 22 is provided with a second fixing post 221, which is integrally formed with the mounting sleeve 22. One end of the first spring is sleeved on the first fixing post 211 and contacts the inner wall of the outer sleeve 21 but is not fixedly connected. The other end of the first spring is sleeved on the second fixing post 221 and contacts the outer wall of the mounting sleeve 22 but is not fixedly connected. This allows for easy disassembly and reassembly between the outer sleeve 211 and the mounting sleeve 22 and the first transverse elastic element 23.

[0022] The transverse elastic element 23 in this invention is not limited to using a first spring. In other embodiments, the transverse elastic element 23 may be a metal sheet, a silicone block, or other elastic objects.

[0023] In this embodiment, the longitudinal elastic element 24 includes two second springs sleeved at both ends of the mounting sleeve 22. When the longitudinal elastic element 24 is a second spring, both ends of the mounting sleeve 22 are provided with retaining rings 222. One end of one of the second springs is in contact with one of the retaining rings 222 but not fixedly connected, and the other end of one of the second springs is in contact with one side of the electronic compass body 1 but not fixedly connected. One end of the other second spring is in contact with the other retaining ring 222 but not fixedly connected, and the other end of the other second spring is in contact with the other side of the electronic compass body 1 but not fixedly connected. At the same time, at least one retaining ring 222 and the mounting sleeve 22 can be detached and disassembled through a detachable connection structure, which facilitates the disassembly and assembly of the anti-vibration electronic compass structure of this utility model.

[0024] The longitudinal elastic element 24 in this invention is not limited to using a first spring. In other embodiments, the longitudinal elastic element 24 may be a metal sheet, a silicone block, or other elastic objects.

[0025] It should be noted that when only one retaining ring 222 is detachably connected to the mounting sleeve 22 via a detachable connection structure, the other retaining ring 222 is integrally formed with the mounting sleeve 22. The detachable connection structure includes a slot 223 on the outer wall of the mounting sleeve 22 and a block 2221 on the inner wall of the retaining ring 222 that cooperates with the slot 223. The slot 223 has an L-shaped structure. The slot 223 and the block 2221 cooperate to facilitate the connection and disconnection between the retaining ring 222 and the mounting sleeve 22. At the same time, one end of the block 2221 is chamfered, which makes it easy to insert the block 2221 into the slot 223.
