Description

Technical Field

[0001] This utility model relates to the field of precision balance technology, specifically to an illuminated handle and a precision balance containing the handle. Background Technology

[0002] Precision balances are weighing instruments used for precise mass measurement. The main types include ordinary precision balances, semi-automatic / fully automatic weight-adding electro-optical projection damping precision balances, and electronic precision balances. Among them, electronic balances have become the mainstream equipment due to their integration of sensing technology, digital electronics technology, and microprocessor technology, and are widely used in laboratories, industrial production, and scientific research.

[0003] Referring to patent application 202420799106.1: An electronic balance tray, in order to obtain accurate measurement results, has an anti-convection cover on the weighing part to prevent airflow from affecting the measurement results. When adding material into the cover, the user's hands and the material container block the light from above, creating a shadow on the weighing platform. This shadow affects the user's observation of the material on the weighing platform. Therefore, there is a need for a structure that can illuminate the weighing platform from one side to assist the user in observing the material on the weighing platform. Utility Model Content

[0036] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0037] like Figures 1 to 3 The illustrated lighting handle includes an elongated mounting plate 1, an elongated handle 3 rotatably mounted at one end of the mounting plate 1, and a light-emitting component 9 mounted on the handle 3. The mounting plate 1 has multiple mounting holes for mounting on a transparent plate 201 of a windproof cover 200. A power control component is provided on the handle 3 to enable the light-emitting component 9 to emit light.

[0038] See Figure 3 The lower end of the mounting plate 1 is provided with a rotating shaft 1-1. A protrusion 2 is detachably mounted on the rotating shaft 1-1 via a screw assembly. The protrusion 2 has a horizontal protrusion 2-1. The handle 3 includes a rotating part 3-1, a housing part 3-2, and a light-emitting part 3-3 connected sequentially. The rotating part 3-1 is sleeved on the rotating shaft 1-1. Two recesses are spaced apart along the circumference of the rotating shaft 1-1 within the rotating part 3-1. After the handle 3 is rotated to its position, the protrusion 2-1 engages within the recesses to restrict the rotation of the handle 3. Specifically, the rotating part 3-1 has a first recess 4-1 along the length of the handle 3 and a second recess 4-2 perpendicular to the length of the handle 3. When the first recess 4-1 engages with the protrusion 2-1, the handle 3 is supported horizontally by the protrusion 2; when the second recess 4-2 engages with the protrusion 2-1, the handle 3 is supported vertically by the protrusion 2. Preferably, see [reference needed]. Figure 1 The rotating part 3-1 is provided with an annular retaining ring 4, which is sleeved on the protrusion 2 and has a first recess 4-1 and a second recess 4-2. In this embodiment, the side wall of the retaining ring 4 is evenly provided with a plurality of threaded holes, and the rotating part 3-1 is provided with a through hole corresponding to the threaded holes to pass through a screw to fix the retaining ring 4. In this embodiment, the protrusion 2 or the retaining ring 4 is made of polyurethane, which has resilience: it can deform slightly during rotation to ensure the smooth rotation of the handle 3, while also taking into account a certain mechanical strength: it can support the handle 3 after it is rotated into place, and has good wear resistance: it reduces the impact on service life caused by the mutual friction between the retaining ring 4 and the protrusion 2 during rotation.

[0039] The compartment 3-2 and the light-emitting part 3-3 are stepped. The light-emitting part 3-3 is away from the mounting plate 1, so that the light-emitting component 9 is away from the mounting plate 1. This allows the user to hold the light-emitting part 3-3, which makes it convenient to rotate the handle 3 or open the transparent plate 201.

[0040] See Figure 1 and Figure 3 The power control assembly includes a battery 5, a control chip, a push-button switch 6, and several wire harnesses. A battery compartment 3-4 is provided on the housing 3-2 for installing the battery 5. A chip slot 3-6 is provided on the light-emitting part 3-3 for placing the control chip. A wire-passing groove 3-5 is provided on the handle 3 for placing the wire harness. A baffle 3-7 is provided near the end of the chip slot 3-6 adjacent to the end of the light-emitting part 3-3. The baffle 3-7 and the end of the light-emitting part 3-3 are arranged opposite to form a slot, and the push-button switch 6 is provided in the slot. See [reference needed]. Figures 1 to 3 In this embodiment, when the button of the push-button switch 6 is pressed, the body of the push-button switch 6 is supported and limited by the baffle 3-7.

[0041] The end of the light-emitting part 3-3 has a button through hole 3-8 corresponding to the button switch 6. The button of the button switch 6 protrudes from the end of the light-emitting part 3-3 through the button through hole 3-8. The light-emitting assembly includes a lamp housing detachably mounted on the light-emitting part 3-3 and a light-emitting strip disposed within the lamp housing. The input and output wires of the light-emitting strip pass through the connection hole 3-6-1 opened on the chip slot 3-6 and are connected to the control chip.

[0042] See Figure 1 and Figure 2 The handle 3 is connected to a cover 7 by screws. The cover 7 is used to close the battery compartment 3-4, the wire channel 3-5, the chip slot 3-6 and the card slot. The cover 7 has a compartment cover hole 7, and a compartment cover 8 is detachably provided on the compartment cover hole 7. The compartment cover 8 is opened to replace the battery 5.

[0043] In this embodiment, the control chip uses an adapter board with an SM5166PF SOP16 patch, which is fixed in the chip slot 3-6 with hot melt adhesive and connected to the pins of the battery 5, the push-button switch 6 and the LED strip through a wire harness.

[0044] See also: Figures 4 to 6A precision balance includes a balance body 100 and a windproof cover 200 disposed on the balance body 100. Transparent plates 201 are openable and closable on the front and left and right sides of the windproof cover 200, and illuminated handles are provided on the transparent plates 201. The handle 3 of the illuminated handle can be rotated to a vertical position to retract and avoid obstructing the user's view; the handle 3 can also be rotated to a horizontal position so that the light-emitting component 9 on the handle 3 corresponds to the weighing platform of the balance body 100.
