DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figs. 1-3 The application provides a high-safety relay, which mainly comprises a relay main body, a shell 1, a base 5 and a stable structure 6. The relay main body is a core component for realizing the function of the relay, and the shell 1 is arranged outside the relay main body. The shell 1 protects the relay main body from the influence of the external environment, such as dust, moisture and mechanical impact. The top of the relay main body is provided with a ceramic insulator 2, a coil 3 and a contact 4. These components are key parts for realizing the electrical function of the relay. The ceramic insulator 2 can effectively prevent current leakage and ensure the safe operation of the relay. The coil 3 generates a magnetic field after being powered on, drives the contact 4 to close or open, and thus realizes the control function of the circuit.

[0021] The base 5 is arranged at the bottom of the relay main body and is a support component of the entire relay. The upper side of the base 5 is provided with left and right slots 51 which are longitudinally arranged and open at the rear side. These slots 51 are designed to facilitate the connection and installation of the relay main body with other devices or components. First, a buckle is arranged on the installation surface and can be clamped in the slots 51 on both sides of the base 5. Then, the base 5 is inserted into the buckle along the slots 51. Finally, the stable structure 6 is used to lift the base 5, so that the base 5 is relatively fixed, the installation is fast and convenient, the base 5 is not easy to fall off, and the safety is high.

[0022] The stable structure 6 comprises a support rod 61 arranged perpendicularly to the base 5, the bottom of the support rod 61 penetrating through the base 5 and extending to the lower side of the base 5, and the support rod 61 and the base 5 being connected in a sliding manner. This design enables the support rod 61 to move up and down in the base 5, thereby achieving the functions of jacking up the relay main body and cooperating with the buckle clamped at the slot 51 to fix the relay main body. The support rod 61 is provided with a support plate 62 at one end of the bottom of the base 5, which can increase the contact area and improve the stability after jacking up.

[0023] In order to realize the longitudinal movement of the support rod 61, a threaded rotating rod 63 is arranged on the upper side of the base 5 corresponding to the support rod 61. The lower end of the threaded rotating rod 63 penetrates downward through the fixed block 52 on the base 5 and is threadedly connected with the top plate of the support rod 61, and the threaded rotating rod 63 and the fixed block 52 are connected in a rotating manner. When it is necessary to fix the relay main body, the threaded rotating rod 63 is rotated, and the threaded cooperation between the threaded rotating rod 63 and the support rod 61 drives the support rod 61 to move upward, and the support plate 62 jacks up the relay main body and fixes the relay main body on the base 5; when it is necessary to disassemble the relay main body, the threaded rotating rod 63 is reversely rotated, and the support rod 61 moves downward, and the support plate 62 returns to the placement groove 55 at the bottom of the base 5, thereby releasing the relay main body and achieving quick disassembly.

[0024] In order to further improve the stability of the movement of the support rod 61, a fixed block 52 is arranged on the upper side of the base 5 corresponding to the support rod 61, and an active cavity 53 for the longitudinal sliding of the support rod 61 is arranged in the fixed block 52. Limiting sliding grooves 54 are longitudinally arranged on the left and right sides of the active cavity 53, and limiting sliding blocks 64 which can longitudinally slide in the limiting sliding grooves 54 are arranged on the left and right sides of the top of the support rod 61 corresponding to the limiting sliding grooves 54. When the support rod 61 moves up and down in the active cavity 53, the limiting sliding blocks 64 slide along the limiting sliding grooves 54, which can effectively limit the lateral shaking of the support rod 61 and ensure that the longitudinal movement of the support rod 61 is more stable and accurate, thereby further enhancing the stability of the relay main body during operation and ensuring its normal working performance.

[0025] In addition, a placement groove 55 for placing the support plate 62 is arranged on the bottom side of the base 5 corresponding to the support plate 62. When the support rod 61 moves downward, the support plate 62 can smoothly enter the placement groove 55, which not only makes the entire device more compact when the relay main body is not installed, but also makes the disassembly process more convenient, avoids interference between the support plate 62 and other components during disassembly, and further simplifies the disassembly process.

[0026] In the actual installation process, first set up the installation surface can be inserted into the slot 51 buckle on both sides of the base 5, and then the base 5 along the slot 51 inserted into the buckle. Then, by rotating the threaded rotating rod 63, the threaded rotating rod 63 and the support rod 61 between the threaded connection will drive the support rod 61 upward, the support plate 62 will be lifted and fixed with the relay body. Because of the threaded connection of the support rod 61 and the threaded rotating rod 63 and the cooperation of the limiting sliding groove 54 and the limiting sliding block 64, the movement of the support rod 61 is stable and reliable, which can ensure that the relay body is firmly fixed on the base 5.

[0027] And in the disassembly process, only need to reverse rotation threaded rotating rod 63, the support rod 61 will move down, the support plate 62 back to the slot 55, that is, the relay body can be released, the disassembly process is very simple, without the use of complex tools or cumbersome steps, greatly improving the efficiency of loading and unloading, facilitating the staff to quickly check, repair or replacement operation.

[0028] Through the above design, the utility model discloses a kind of high safety relays, compared with traditional suction cup fixed mode, its mechanical structure is more reliable, and the problem that suction cup does not appear because surface requirement is high or long time adsorption falls off. Through the cooperation of the support rod 61 and the threaded rotating rod 63, the stability of the relay during operation can be significantly improved, to avoid the loosening or even falling off of the relay due to vibration, impact and other harsh environmental conditions, thereby improving the safety of the relay. At the same time, the limiting sliding groove 54 in the movable cavity 53 cooperates with the limiting sliding block 64 on the support rod 61, so that the longitudinal movement of the support rod 61 is more stable, further enhancing the stability of the relay body, and ensuring its normal working performance. In addition, the loading and unloading operation of the relay is very simple, and the relay body can be lifted and fixed by rotating the threaded rotating rod 63, without the need for complex tools or cumbersome steps, compared with the traditional bolt fixing mode, greatly improving the efficiency of loading and unloading, facilitating the staff to quickly install and disassemble, which is conducive to daily maintenance and maintenance, and facilitates the inspection, repair or replacement of the relay body, reduces the maintenance cost and time cost.
