DETAILED DESCRIPTION

[0043] The following will be described in detail in combination with the accompanying Figures 1-6 The present application will be further described in detail.

[0044] The embodiment of the present application discloses a host for a liquid level detection device.

[0045] A host for a liquid level detection device mainly comprises a shell and a main control board. The shell is composed of an upper cover 1 and a bottom cover 2, and the upper cover 1 and the bottom cover 2 jointly enclose a cavity for placing the main control board. On the upper cover 1, a plurality of locking rods 3 are arranged circumferentially along the center line of the upper cover 1; correspondingly, on the bottom cover, a plurality of locking cylinders 4 are arranged circumferentially along the center line of the bottom cover, and the locking rods 3 and the locking cylinders 4 can be inserted and matched. Moreover, the locking cylinder 4 is internally provided with a movable locking block 5, and the rod wall of the locking rod 3 is provided with an annular locking groove 31.

[0046] When the host needs to be installed, the operator only needs to insert the locking rod 3 into the locking cylinder 4 and insert the locking block 5 into the locking groove 31. At this time, the locking block 5 plays a limiting role on the upper cover 1 through the locking rod 3, thereby greatly improving the convenience of installing the host.

[0047] Further, the inner wall of the locking cylinder 4 is provided with a placement groove 41, and the placement ring 6 is installed in the placement groove 41. The placement ring 6 is coaxial with the locking cylinder 4 and is in a rotating fit relationship with the placement groove 41. On the side wall of the placement groove 41, a plurality of guide blocks 42 are distributed circumferentially along the center line of the placement groove 41. The two ends of the guide blocks 42 are not the same size, and the narrow part to the wide part is a smooth curve transition.

[0048] At the same time, the inner wall of the placement ring 6 is provided with a guide groove 62 penetrating the outer wall of the placement ring 6, and the guide groove 62 is provided with a pushing piece 61. The pushing piece 61 and the locking block 5 slide in the guide groove 62, and the pushing piece 61 is located between the guide block 42 and the locking block 5. When the placement ring 6 rotates, the guide block 42 will move the pushing piece 61 in the guide groove 62 due to the contact between the guide block 42 and the pushing piece 61, and in turn push the locking block 5 to move, thereby achieving the operation of inserting the locking block 5 into the locking groove 31.

[0049] In the embodiment of the application, the pushing piece 61 is provided in a spherical shape, so that the pushing piece 61 and each contact position are in rolling fit, thereby effectively reducing the moving resistance of the pushing piece 61 and significantly improving the pushing effect of the pushing piece 61.

[0050] In addition, the outer wall of the placement ring 6 is provided with a magnetic block 63, and the guide block 42 is provided with a magnetic material that is attracted to the magnetic block 63. When the attractive force between the guide block 42 and the magnetic block 63 is greater than the rotational resistance of the placement ring 6, the attractive force between the guide block 42 and the magnetic block 63 will drive the placement ring 6 to rotate in a certain direction. During the rotation of the placement ring 6, the guide block 42 pushes the pushing piece 61 to move in the guide groove 62, and in turn pushes the locking block 5 to move.

[0051] In order to further improve the stability of the connection between the magnetic block 63 and the guide block 42, the magnetic block 63 and the guide block 42 are provided with a matching abutting surface. When the magnetic block 63 and the guide block 42 are in contact, they can be tightly abutted to increase the contact area and improve the connection stability.

[0052] Meanwhile, a separation block 7 is arranged between the guide block 42 and the magnetic block 63, so as to reduce the possibility that the guide block 42 and the magnetic block 63 are initially adhered together. The separation block 7 is made of light material, and the guide block 42 and the magnetic block 63 hold the separation block 7 through the attraction force therebetween. In addition, the separation block 7 is provided with a push plate 71. After the locking rod 3 is inserted into the locking cylinder 4, when the locking block 5 and the push plate 71 are in contact, the locking block 5 is located at the edge of the insertion range of the locking groove 31. At this time, when the locking rod 3 continues to push the push plate 71, the push plate 71 will drive the separation block 7 to move out of the range between the guide block 42 and the magnetic block 63, so that the magnetic block 63 is driven to move towards the guide block 42 under the action of the magnetic force, and in turn drives the placement ring 6 to rotate.

[0053] Finally, the spherical pusher 61 pushes the locking block 5 to be inserted into the locking groove 31 under the action of the guide block 42, and the installation of the host computer is successfully completed.

[0054] In addition, the top of the locking block 5 and the bottom of the locking rod 3 are both provided with inclined surfaces. When the locking block 5 and the locking rod 3 are in contact, the inclined surfaces on the locking block 5 and the locking rod 3 can guide the locking rod 3 to push the locking block 5 into the guide groove 62.

[0055] In addition, the inner wall of the locking cylinder 4 is provided with a spiral groove 43 along the axial direction of the locking cylinder 4, and the rod wall of the locking rod 3 is provided with a protrusion 32 which is in sliding fit with the locking groove 31. The locking rod 3 is in rotational fit with the upper cover 1, and after the locking rod 3 is inserted into the locking cylinder 4, the locking rod 3 will rotate around its own axis during the linear motion due to the movement of the protrusion 32 in the locking groove 31. When the locking rod 3 and the locking block 5 are in contact, the synchronous linear motion and rotation of the locking rod 3 further improves the convenience of pushing away the locking block 5.

[0056] In order to facilitate the protrusion 32 on the locking rod 3 to be placed in the spiral groove 43, the locking rod 3 and the upper cover 1 are temporarily positioned through gluing. When the groove wall of the spiral groove 43 makes the locking rod 3 rotate through the protrusion 32, the locking rod 3 can break away from the adhesive force of the glue and rotate.

[0057] The implementation principle of the host of the liquid level detection device is as follows: the locking rod 3 of the upper cover 1 is inserted into the lower cover locking cylinder 4, the locking block 5 in the locking cylinder 4 is inserted into the locking groove 31 of the locking rod 3 under the cooperation of the placing ring 6, the guide block 42 and the pushing piece 61, the fixing of the upper cover 1 and the lower cover is completed, the magnetic block 63 on the outer wall of the placing ring 6 and the magnetic material in the guide block 42 are attracted to each other, the placing ring 6 is driven to rotate after overcoming the rotating resistance of the placing ring 6, and then the locking block 5 is inserted into the locking groove 31, the inclined surface at the bottom of the locking rod 3 cooperates with the inclined surface at the top of the locking block 5 to guide, and the protrusion 32 on the locking rod 3 slides in the spiral groove 43 on the inner wall of the locking cylinder 4, so that the locking rod 3 rotates synchronously in the inserting process, the locking block 5 is further pushed, and finally the convenient installation of the host is realized.

[0058] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
