[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] See also Figure 1-3 This is an embodiment of a wide-angle ammeter of the utility model.

[0024] It includes an ammeter body 1, a dial 2 is provided on the front end face of the ammeter body 1, and a mounting shell 3 is provided behind the dial 2; a mounting assembly 4 is provided on the rear end face of the mounting shell 3; the mounting assembly 4 includes a mounting groove 41 provided on the rear end face of the ammeter body 1, a rotating shaft 42 with a damper is provided in the mounting groove 41, a mounting plate 43 is keyed on the rotating shaft 42, and a first mounting hole 44 is provided on the mounting plate 43; a fixing hole 45 is also provided on the rear end face of the mounting shell 3, the fixing hole 45 has the same diameter as the first mounting hole 44, and when the mounting plate 43 is received in the mounting groove 41, the first mounting hole 44 coincides with the fixing hole 45.

[0025] The size of the dial 2 of this device can be made according to the size required by the customer, and is not limited by the size of the shell. The production of the existing new material shell requires an injection mold, and the production cost of the injection mold is relatively high, more than 5,000 yuan. And the cycle is long, 30-40 days; after removing the plastic shell, the 1.0mm aluminum dial 2 is used to fix the meter rotation mechanism to make an ammeter. The size of the dial 2 can be made according to customer requirements, and the cost is relatively low, between 1,000-2,000 yuan. The positive and negative input ends use screw rods or wires.

[0026] The cycle is also short, about 10 days; it can be round, square, or rectangular, determined by the customer, and the integration with the customer's products is greatly improved; third: embedded installation can be achieved.

[0027] At the same time, the device also improves the mounting assembly 4 at the rear end of the ammeter body 1; a rotatable mounting plate 43 is provided. When the mounting plate 43 is placed in the mounting groove 41, a screw can be used to penetrate the mounting frame or the mounting plate, and then the screw can be screwed into the first mounting hole 44, and then screwed into the fixing hole 45; the ammeter body 1 can be fixed;

[0028] When the mounting plate 43 is rotated ninety degrees, the mounting plate 43 is in a horizontal state, and the mounting plate 43 can be fitted with the upper surface of the mounting frame, and then the mounting frame is penetrated by bolts, the bolts are screwed into the first mounting holes 44, and finally fixed to the mounting frame with nuts.

[0029] Therefore, according to the structural design of the device, the ammeter body 1 can be hung and directly installed, and the operation is very convenient.

[0030] A damper is arranged on the rotating shaft 42 in the device, and the damping value of the damper is very small; the main function of arranging the damper is to keep the mounting plate 43 in the mounting groove 41 at all times when the ammeter body 1 is not installed.

[0031] The mounting plate 43 is further provided with a second mounting hole 46. The mounting shell 3 is cylindrical. The axis of the second mounting hole 46, the axis of the first mounting hole 44 and the axis of the mounting shell 3 are on the same plane, and the angle between the plane and the vertical plane is 45°.

[0032] The second mounting hole 46 provided in the device provides more mounting methods for the ammeter body 1; when there is no mounting frame or mounting plate, but only a wall, the mounting plate 43 can be attached to the wall, and then screwed into the second mounting hole 46 with a screw, and the screw will also make a threaded hole in the wall, so that the ammeter body 1 can be fixed to the wall.

[0033] At the same time, when the mounting plate 43 is rotated ninety degrees, the mounting plate 43 is in a horizontal state; when the mounting plate 43 is fixed to the upper end surface of the mounting frame, the design of the second mounting hole 46 will also provide a new mounting point for installation. The staff can choose the second mounting hole 46 or the first mounting hole 44, or both, according to the specific situation.

[0034] There are four mounting grooves 41 , which are evenly arranged on the rear end surface of the ammeter body 1 .

[0035] There are generally four installation points in the prior art, and the four installation slots 41 of the present device are also provided to facilitate the stable installation of the ammeter body 1 .

[0036] The mounting plate 43 is made of stainless steel, and the first mounting hole 44 , the second mounting hole 46 , and the fixing hole 45 are all threaded holes.

[0037] Stainless steel has high strength, is not prone to deformation or rust, and has a long service life; the first mounting hole 44, the second mounting hole 46, and the fixing hole 45 are all threaded holes mainly to facilitate the installation of screws or bolts.

[0038] The shape of the mounting plate 43 is a right-angled trapezoid, and the inclined angle of the hypotenuse of the mounting plate 43 is 45°.

[0039] The shape of the mounting plate 43 is set in this way mainly to save materials as much as possible under the condition of achieving the above-mentioned mounting function, and the strength of the mounting plate 43 will not be reduced.

[0040] The bevel angle of the mounting plate 43 is 45°, mainly because the axis of the second mounting hole 46, the axis of the first mounting hole 44, and the axis of the mounting shell 3 are on the same plane, and the angle between the plane and the vertical plane is 45°; such a setting is more beautiful and stable.

[0041] A mounting block is disposed in the mounting shell 3 . The mounting block and the mounting shell 3 are integrally formed, and a fixing hole 45 is disposed in the mounting block.

[0042] The mounting shell 3 is integrally injection molded, and a mounting block structure is added to the injection mold; the purpose is to use the mounting block to set the fixing hole.

[0043] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
