Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0015] Such as figure 1 As shown, a shock-proof structure of a high-precision small-torque standard device includes a glass protective cover 1, a marble base 3, a jack 4, an elastic shock-isolating material 5, and a shock-proof trench cover 6.

[0016] The glass protective cover 1 completely covers the high-precision small torque standard device 2 . The glass constituting the protective cover is double-layer glass with a film in the middle. After treatment, the protective cover is firm and not fragile, and has anti-static function. Each side of the glass splicing is sealed with silicone. Dodge door is arranged on the glass protective cover 1, is convenient to manual adjusting device. A silicone sheet is pasted around the movable door to block the gap with other glass when it is closed, so that the protective cover forms an airtight airtight state.

Abstract

The invention relates to a shockproof structure of a high-precision small-torque standard device. Three jacks are distributed under a marble base for fixing the high-precision small-torque standard device and a glass protective cover evenly, and a layer of elastic shock insulation materials are arranged between the jacks and a concrete base. The concrete base is provided with a shockproof ditch, the glass protective cover covers the high-precision small-torque standard device and is made of double layers of glass, a film is attached between double layers of glass, a movable door allowing the device to be adjusted manually and conveniently is arranged on the glass protective cover, and silicon sheets are attached around the movable door. By means of multi-layer insulation design, ground shock can be effectively prevented. By means of three-point type structural design, the base of the device can be ensured to be horizontal and stable while shock is prevented. By means of the multi-layer glass protective cover with the film, influence caused by air flowing is prevented, and electrostatic influence can be shielded. Therefore, the effective and comprehensive shockproof technology is provided.

Description

technical field [0001] The invention relates to a measurement detection, torque detection calibration, and torque testing device, in particular to a shockproof structure of a high-precision small torque standard device. Background technique [0002] The static weight torque standard device uses the gravity of the weight as the standard force value, and generates a standard torque through the action of the lever arm directly or after being amplified by a certain lever mechanism. For high-precision small-torque standard devices, small sound waves, air flow, and ground vibrations will affect their measurement accuracy. Therefore, how to prevent the external environment from affecting it is a necessary condition for realizing high precision. This patent provides a realizable anti-vibration technology for solving the above problems. Different from the commonly used anti-vibration ditch design in the past, this patented design can more effectively and comprehensively prevent vib...
