Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, and in particular to a convenient gripping device for handheld spectrometers. Background Technology

[0002] A handheld spectrometer is a spectroscopic analysis instrument based on XRF (X-ray Fluorescence) spectroscopy technology. It mainly consists of an X-ray tube, detector, CPU, and memory. Due to its portability, high efficiency, and accuracy, it has important applications in fields such as alloys, ores, environmental studies, and consumer products. Handheld spectrometers require high resolution and signal-to-noise ratio, good intensity and wavelength accuracy, strong resistance to external interference, and excellent instrument stability.

[0003] Existing patents, such as Chinese Patent Publication No. CN220231541U, relate to the field of sample component detection technology and disclose a handheld spectrometer, including a main body. A white light detector is fixedly installed near the top of the main body, an infrared detector is fixedly installed below the white light detector, and an X-ray detector is fixedly installed below the infrared detector. In this invention, when the information collected by the three sets of photosensitive elements is transmitted to the amplifier for amplification and then undergoes preliminary detection by the detector, it is finally summarized in the collector for component comparison. Through multi-faceted comparison to eliminate errors, it has higher accuracy than traditional single-beam detection, and each detector can be used independently, expanding the sample detection range.

[0004] While the aforementioned patented technology utilizes three sets of photosensitive elements to transmit collected information to an amplifier for amplification, followed by preliminary detection by a detector, and finally summarizing the data in a collector for component comparison, achieving higher accuracy than traditional single-beam detection through multi-faceted comparison and error elimination, and each detector can be used independently, expanding the sample detection range, the handheld spectrometer's handle is fixedly connected to the main body at a fixed angle. Different operators have different hand sizes and grip habits, and the fixed angle cannot accommodate "personalized grip needs." Furthermore, in complex detection scenarios, the hand must be forced to adapt to the fixed angle, easily leading to muscle fatigue, operational instability, and probe alignment deviation, affecting data accuracy and reducing detection efficiency. Additionally, the handle's exposed design, when idle or carried, occupies extra space, increasing the difficulty of storage and transport. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the above-mentioned patented technology, where the handle of the handheld spectrometer is fixedly connected to the body, the angle is fixed, and it is inconvenient to store the handle. Therefore, a convenient gripping device for the handheld spectrometer is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a convenient gripping device for a handheld spectrometer, comprising a spectrometer body, a groove being formed at the bottom of the spectrometer body, a hand handle being rotatably connected to a bearing near one end of the groove, an arc groove being formed at the top of the hand handle near the center, a worm gear-shaped arc plate being fitted and fixedly connected to the inner arc wall of the arc groove, a rotating rod being provided above the worm gear-shaped arc plate, a worm being fitted and fixedly connected to the surface of the rotating rod, and the worm engaging with the worm gear-shaped arc plate.

[0007] Preferably, a trapezoidal block is fixedly connected to the top of the spectrometer body near one end, and a display screen is fixedly installed on one side of the trapezoidal block.

[0008] Preferably, the surface of the hand handle is provided with an annular groove, and an anti-slip rubber sleeve is fitted and fixedly connected inside the annular groove.

[0009] Preferably, a square groove is formed at one end of the arc wall of the groove, the rotating rod is located inside the square groove, and one end of the rotating rod passes through the spectrometer body from the inner wall of one end of the square groove and is rotatably connected to its bearing.

[0010] Preferably, a drive motor is embedded and fixedly connected to one end of the spectrometer body and located at the rotating rod, and the output end of the drive motor is fixedly connected to one end of the rotating rod.

[0011] Preferably, a fixing block is provided inside the arc groove and near one end, the top of the fixing block is fixedly connected to the inner wall of the top of the groove, and the other end of the rotating rod is fixedly connected to the fixing block.

[0012] Preferably, a groove is formed on the surface of the spectrometer body near one end, a controller is embedded and fixedly installed inside the groove, a control button is installed on the surface of the controller, and the controller is electrically connected to the drive motor.

[0013] Preferably, the surfaces of the spectrometer body and the trapezoidal block, especially near the edges, are rounded.

[0014] Preferably, the groove is adapted to the hand handle.

[0015] Preferably, the surface of the anti-slip rubber sleeve is provided with anti-slip texture.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, through the linkage structure of the drive motor, rotating rod, worm gear, and hand handle, pressing the control button drives the motor, which in turn drives the rotating rod and worm gear-shaped arc plate to rotate, enabling the hand handle to be adjusted at multiple angles within the groove. Regardless of the operator's habits or testing posture, the grip angle can be flexibly adjusted, allowing the hand to be natural and comfortable, avoiding fatigue and operational instability, and ensuring testing accuracy and efficiency. It is especially suitable for complex working conditions such as high altitudes and confined spaces.

[0018] 2. In this utility model, when the device is idle, the drive motor can reverse to precisely reset the handle into the groove, realizing the "hidden storage" of the handle. After storage, the device has a neat appearance, reduces space occupation, and is easy to put into a backpack or toolbox for carrying. At the same time, storing the handle in the groove can avoid external impact and sand and dust erosion, protect the integrity of the handle structure, extend the life of the device, reduce maintenance costs, and improve the portability and durability of the device.
