Abstract
Description
Technical Field
[0001] This utility model relates to a battery fixing structure, and more particularly to a battery locking device and an infrared thermal imager. Background Technology
[0002] An infrared thermal imager is a device that converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors in the thermal image represent different temperatures of the object being measured. The core of an infrared thermal imager is an infrared detector.
[0003] In the prior art, infrared thermal imagers include a housing, on which lens assemblies, infrared detectors, and power supply circuits for powering the corresponding infrared detectors are disposed. In the prior art, for the convenience of power supply, batteries are usually used to power the power supply circuit, that is, the positive and negative terminals of the battery are connected in series in the power supply circuit.
[0004] In existing technology, the battery is connected to the casing via a battery slot. The battery slot has a first terminal connection structure and a second terminal connection structure at each end. During use, the battery is inserted into the slot, with the positive terminal connected to the first terminal connection structure and the negative terminal connected to the second terminal connection structure. This powers the circuit and supplies power to the infrared detector. The battery slot opening is secured with a cover plate by screws. Replacing the battery requires opening the cover plate with a screwdriver, which is inconvenient, especially in the field where a screwdriver is unavailable. Furthermore, the battery is not securely fixed in this technology. When the infrared thermal imager is used in a vibrating environment, the battery may vibrate and become loose, causing a power outage. Utility Model Content

[0023] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0025] An embodiment of an infrared thermal imager in this utility model is as follows: Figures 1-6 As shown:
[0026] The infrared thermal imager includes a housing 1 containing an infrared detector, a power supply circuit for electrical connection with the infrared detector, a battery mounting slot 7 on the housing, and a battery 6 for supplying power to the power supply circuit. The battery 6 is connected to the housing 1 via a battery locking device.
[0027] The battery locking device includes a battery cover 2 whose front end is hinged to the housing 1. The front end of the battery cover 2 is hinged to the housing 1 via a hinge shaft 9. A battery storage structure is provided on the side of the battery cover 2 facing the battery mounting slot 7. The battery storage structure includes a C-shaped clamp 8 for holding the battery in place. The C-shaped clamp 8 is elastic, and the inlet size of the C-shaped clamp 8 is smaller than the diameter of the battery 6. After the battery is secured to the C-shaped clamp 8, radial movement of the battery can be restricted.
[0028] The battery storage structure also includes a battery tail support 5 located at the rear end of the battery flip cover 2. The front end of the battery tail support 5 has a battery positioning groove for positioning and engaging with the rear end of the battery. The battery tail support is made of metal. A negative electrode conductor 13 with a cup-shaped structure is located in the battery positioning groove. A battery clamping spring 12 is positioned between the negative electrode conductor 13 and the rear electrode (i.e., the negative terminal) of the battery. A silicone gasket 14 is also positioned between the battery tail support 5 and the rear end of the battery. In other words, the rear electrode, i.e., the negative terminal, is electrically connected to the negative electrode conductor 13 and the battery tail support 5 through the battery clamping spring 12. The front end of the battery flip cover 2 has a battery front stop 11 for engaging with the front end of the battery to limit the forward movement of the battery. The battery 6 is securely positioned between the battery front stop 11 and the battery clamping spring 12. The rear end face of the battery tail support 5 is a sloping structure that gradually slopes downwards from top to bottom and from back to front.
[0029] The battery flip cover 2 has an installation station for rotating the battery into the battery mounting slot and a disassembly station for rotating the battery away from the battery mounting slot during the flipping process around its own axis.
[0030] The front side of the battery mounting slot is provided with a front contact electrode structure for electrical contact with the front electrode (positive terminal 10) of the battery when the battery cover is in the installation position. The rear side of the battery mounting slot is provided with a rear contact electrode structure for contact with the rear electrode of the battery when the battery cover is in the installation position. In this embodiment, the front contact electrode structure is a conical spring connected to the power supply circuit. The front end of the conical spring is connected to the housing. When the battery cover is in the installation position, the rear end of the conical spring abuts against the front electrode (positive terminal) of the battery.
[0031] The rear contact electrode structure is a U-shaped negative electrode spring 15 connected to the power supply circuit. The rear end of the negative electrode spring 15 is connected to the housing. When the battery cover is in the installation position, the rear end face of the battery tail support 5 abuts against the negative electrode spring 15. At this time, the battery negative electrode is electrically connected to the negative electrode spring 15 through the battery pressing spring 12, the negative electrode conductor 13, the battery tail support 5, and the negative electrode spring 15.
[0032] The rear end of the battery cover is provided with a reciprocating flip cover stop bar 4. The housing 1 is provided with a stop bar mating groove for use with the flip cover stop bar 4. During the reciprocating movement of the flip cover stop bar, there is a locking position where the flip cover is inserted into the stop bar mating groove to lock the battery cover to the installation position. During the reciprocating movement of the flip cover stop bar 4, there is also an unlocking position where the flip cover is moved out of the stop bar mating groove to unlock the battery cover.
[0033] In this embodiment, the axis of the flip cover stop 4 extends in the front-to-back direction. The flip cover stop 4 is threadedly connected to the battery flip cover 2. A dial 3 is provided on the flip cover stop 4. In use, the flip cover stop 4 can be rotated by flicking the dial 3 with a finger, allowing the flip cover stop 4 to move back and forth. When the rear end of the flip cover stop 4 moves backward into the stop mortise groove, the flip cover stop is in the locked position, and the battery flip cover cannot be opened. When the rear end of the flip cover stop 4 moves forward and moves out of the stop mortise groove, the flip cover stop is in the unlocked position, and the battery flip cover can be opened.
[0034] In this embodiment, a reset torsion spring is sleeved on the hinge shaft to force the battery cover to flip from the installation position to the disassembly position. Thus, when the cover lever is in the unlocking position, the battery cover can automatically flip open under the action of the reset torsion spring.
