[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See also Figures 1 to 6 , the utility model provides a technical solution:

[0021] A multimeter bracket adjustable structure comprises a bracket assembly 1 and a multimeter back cover 2. A multimeter battery cover 21 is fixedly mounted on the multimeter back cover 2. The multimeter battery cover 21 is arranged at the upper end of the multimeter back cover 2. A slotted shaft hole 22 and a battery cover housing side wall 23 are arranged at the bottom end of the multimeter battery cover 21. A rotating shaft 11 is arranged on the bracket assembly 1. The bracket assembly 1 is rotatably connected to the slotted shaft hole 22 through the rotating shaft 11. The side where the bracket assembly 1 is connected to the rotating shaft 11 is in an arc shape, and the rotating shaft 11 is arranged at the center of the arc. The fully assembled bracket assembly 1, the rotating shaft 11 and the slotted shaft hole 22 are assembled. The assembled multimeter back cover 2 and the bracket assembly 1 are flexible to flip without jamming. Figure 2 As shown, when the bracket assembly 1 is rotated to the maximum support angle, it is fixed by abutting against the side wall 23 of the battery cover housing; Figure 4 As shown, one end of the bracket assembly 1 connected to the rotating shaft 11 is provided with an elastic arm 13, that is, the end of the bracket assembly 1 connected to the rotating shaft 11 has a certain elasticity. When the bracket assembly 1 needs to be disassembled, Figure 3 As shown, the upper part of the multimeter is pressed hard. Under the action of force and due to the limitation of the side wall 23 of the battery cover shell, the elastic arm 13 of the bracket assembly 1 is deformed, and the size of the slotted shaft hole 22 becomes larger, so that the bracket assembly 1 is disengaged; the elastic arm 13 is provided so that it can be deformed at the moment when the bracket assembly 1 is disengaged, and then recover after being disengaged, and the bracket assembly 1 will not be damaged; the purpose of this arrangement is to prevent the bracket assembly 1 and the shaft 11 from being twisted, damaged or even broken in the case of overpressure, that is, in the case of overpressure, after the bracket assembly 1 rotates to the maximum supporting angle, the slotted shaft hole 22 becomes larger and disengages, thereby protecting the bracket assembly 1.

[0022] A blind hole is provided in the middle of the multimeter back cover 2, and a positioning structure 3 is installed inside the blind hole. The positioning structure 3 is used to cooperate with the bracket assembly 1 to complete support at different angles; the positioning structure 3 includes a spring 31 fixedly installed inside the blind hole, and the other end of the spring 31 is fixedly connected to a positioning bead 32. A plurality of limiting ribs 12 are provided on one end of the bracket assembly 1 for cooperating with the positioning structure 3. The plurality of limiting ribs 12 are arranged in a circular array with an angle of 30° with the rotating shaft 11 as the center, and the positioning bead 32 is clamped between two adjacent limiting ribs 12 to fix the bracket assembly 1; Figure 2 As shown, the position where the blind hole is provided on the back cover 2 of the multimeter is recessed inward by a certain distance, and its function is that when the bracket assembly 1 needs to be disassembled, one end of the bracket assembly 1 with the limiting rib 12 can slide out naturally without the elastic arm 13, that is, the front end of the bracket assembly 1 is divided into several parts, and one end of the bracket assembly 1 in the middle part is provided with a limiting rib 12 cooperating with the positioning structure 3, and one end of the bracket assembly 1 on the other two sides is provided with an elastic arm 13;

[0023] When it is necessary to flip to different angles, the limiting rib 12 presses the positioning bead 32, thereby compressing the spring 31 to deform, and the bracket assembly 1 can be flipped smoothly. Since the limiting ribs 12 are arranged in a circular array with an angle of 30° with the rotating shaft 11 as the center, and there are three limiting ribs 12 in total, that is, the limiting ribs 12 on the bracket 3 and the multimeter battery cover 21 can allow the bracket assembly 1 to have 3 different opening angles, so that the state of the bracket assembly 1 after opening is divided into 3 states, namely, the state with a support angle of 30°, the state with a support angle of 60° and the state with a support angle of 90°.

[0024] The working principle of the above-mentioned adjustable structure of the multimeter bracket is as follows:

[0025] When the device is in use, the bracket assembly 1 is rotated. During the rotation process, the limiting rib 12 at the end of the bracket assembly 1 presses the positioning bead 32. Under the action of the spring 31, the positioning bead 32 retracts inward until the limiting rib 12 passes through, and the positioning bead 32 rebounds. At this moment, the positioning bead 32 is located between two adjacent limiting ribs 12 to limit the bracket assembly 1. The bracket assembly 1 can be flipped in sequence to form a state with a support angle of 30°, a state with a support angle of 60°, and a state with a support angle of 90°; and when the bracket assembly 1 needs to be disassembled, it is only necessary to press the upper part of the multimeter hard. Under the action of force, and due to the limitation of the side wall 23 of the battery cover shell, the elastic arm 13 of the bracket assembly 1 is deformed, and the size of the slotted shaft hole 22 becomes larger, so that the bracket assembly 1 is disengaged.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
