[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0031] According to embodiments of the present invention, on the one hand, such as Figures 1 to 4 As shown, an instrument fixing device is provided, including a clamping assembly 1, a mounting base 2, and a ball joint shaft 3. The clamping assembly 1 is adapted to clamp a bracket and has an open state that is separated from the bracket and a clamping state that clamps the bracket. One side of the mounting base 2 is adapted to install an instrument, and the ball joint shaft 3 connects the clamping assembly 1 and the side of the mounting base 2 away from the instrument.

[0032] Specifically, in this embodiment, the mounting base 2 is not specifically limited. For example, in this embodiment, the mounting base 2 is cubic in shape, and the shape of the mounting base 2 matches the mounting groove on the back of the instrument. When the mounting base 2 is inserted into the mounting groove, it can support the instrument. The two ends of the ball joint shaft 3 are respectively connected to the clamping assembly 1 and the mounting base 2. The clamping assembly 1 can be clamped on the bracket of the photovoltaic equipment, and the ball joint shaft 3 can adjust the angle of the mounting base 2.

[0033] This utility model, by setting up a clamping component 1, facilitates clamping the instrument fixing device onto brackets of various materials, thereby improving the applicability of the instrument fixing device. At the same time, the ball joint shaft 3 allows the mounting base 2 to be adjusted to different directions, so that operators can perform testing from different positions. It has the advantages of simple structure and convenient operation.

[0034] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly 1 includes a clamping member 101 and an elastic member 102. The two clamping members 101 are hinged on one side, the mounting part 302 is disposed on the clamping member 101, and the elastic member 102 is disposed between the two clamping members 101.

[0035] Specifically, in this embodiment, the clamping member 101 is not specifically limited. For example, in this embodiment, the clamping member 101 has a plate-like structure. The middle part of the two clamping members 101 is hinged by a pin. The mounting base 2 is connected to the operating end of one of the clamping members 101. The elastic member 102 is disposed between the two clamping members 101. The elastic force of the elastic member 102 can drive the clamping ends of the two clamping members 101 to move closer to each other. In use, by squeezing the operating end of the clamping member 101, the clamping ends of the clamping member are separated from each other. After the clamping member 101 is clamped on the bracket, the elastic force of the elastic member 102 clamps the clamping member 101 on the bracket.

[0036] In this embodiment, the elastic element 102 is not specifically limited. For example, in this embodiment, the elastic element 102 is a torsion spring, which is mounted on a pin.

[0037] This utility model can clamp different supports by using two clamping members 101. The elastic force of the elastic member 102 can apply an elastic force to the clamping member 101 to restore its original position, so that the clamping member 101 is firmly clamped on the support.

[0038] In one embodiment, such as Figure 1 As shown, the mounting base 2 is provided with a tray 201, and the tray 201 is provided with a micro switch.

[0039] Specifically, in this embodiment, the micro switch utilizes a parallel retractable arm structure, so that when the instrument presses against the support plate 201, it drives the internal linkage structure. Under the action of gravity, the instrument will press down on the lower arm, triggering the linkage mechanism. The left and right arms will automatically clamp the instrument inward. The heavier the instrument, the tighter the clamping will be.

[0040] In this embodiment, as Figure 5 As shown, the micro switch includes a lower pressure block 203 and two retractable arms 204. The lower pressure block 203 is movably disposed in the opening in the middle of the support plate 201. The lower pressure block 203 has a first tooth on its side. The two retractable arms 204 are movably disposed in the openings on both sides of the support plate 201. The retractable arms 204 have a second tooth. The end of the retractable arm 204 away from the second tooth is L-shaped and used to clamp the instrument. The first tooth and the second tooth mesh. When the instrument applies pressure to the lower pressure block 203, the lower pressure block 203 moves downward, causing the two retractable arms 204 to move closer to each other and clamp the instrument.

[0041] When the instrument is installed on the mounting base 2, the micro switch is activated to achieve automatic clamping of the clamping component 1.

[0042] In one embodiment, such as Figure 3 and Figure 4 As shown, the clamping member 101 has slots on both sides, and an adjustment plate 103 is movably installed in the slots.

[0043] Specifically, in this embodiment, each clamping member 101 has a mounting groove on both sides, and an adjustment plate 103 is movably installed in the mounting groove. The clamping area of ​​the clamping member 101 can be adjusted by adjusting the extension length of the adjustment plate 103 in the mounting groove.

[0044] This utility model is equipped with an adjustment plate 103, which can be pulled to lengthen the clamping member 101 to accommodate brackets of different sizes.

[0045] In one embodiment, the clamping member 101 has a plurality of anti-slip pins on the opposite side.

[0046] Specifically, in this embodiment, the anti-slip nails are made of silicone. When the clamping force is greater than 15N, the silicone nails deform and fill the gap between the clamping member 101 and the bracket, forming a three-point global constraint.

[0047] The anti-slip pins in this invention can increase the friction between the clamping component 101 and the support component, thereby improving the stability of the clamping assembly 1 in clamping the support and reducing the shaking of the overall device.

[0048] In one embodiment, the ball joint shaft 3 is provided with a locking button.

[0049] Specifically, in this embodiment, the locking button is a clamping screw located on the side of the ball head 301. The arc surface at the front end of the clamping screw contacts the lower part of the ball head 301. The rotational motion of the clamping screw is converted into radial linear motion, which generates friction with the universal rotating spindle of axial linear motion and rotational motion, thereby achieving a locking state at any position.

[0050] This utility model has a locking button on the ball joint shaft 3. When the user adjusts the instrument on the base to a suitable position, the locking button can be adjusted to lock the ball joint shaft 3, keeping the instrument in that position and facilitating the user's measurement operation.

[0051] In one embodiment, the clamping assembly 1 is provided with a magnet.

[0052] Specifically, in this embodiment, the clamping assembly 1 with a magnet can increase the adsorption of the rigid support. The clamping assembly 1 can be installed on the steel support by magnetic attraction, or it can be engaged with the concrete support by the anti-slip nails in the clamping member 101, or it can be clamped on the support-like structure by the ring plate of the clamping member 101.

[0053] This invention provides a magnet on the clamping component 1. When clamped on a rigid support, the magnet can provide auxiliary stability to the clamping component 1 through magnetic attraction.

[0054] In one embodiment, such as Figure 1 As shown, the ball joint shaft 3 includes a ball head 301 and a mounting part 302. One end of the ball head 301 is mounted on the mounting base 2 or the clamping assembly 1, and one end of the mounting part 302 is mounted on the clamping assembly 1 or the mounting base 2. The mounting part 302 is provided with a mounting cavity that matches the ball head 301. The ball head 301 is movably mounted in the mounting cavity, and the mounting cavity is provided with damping fluid.

[0055] Specifically, in this embodiment, one end of the ball head 301 is spherical, and the other end is provided with a connecting post. The connecting post is connected to the mounting base 2. The mounting part 302 is cylindrical. One end of the mounting part 302 is connected to the clamping member 101. The end of the mounting post away from the clamping member 101 is provided with a spherical mounting cavity. The spherical end is movably installed in the mounting cavity. The mounting cavity is provided with damping fluid. The damping can also increase the damping torque of the ball hinge shaft 3 to 0.5 N·m to 5 N·m. When the wind speed is high, the instrument reading fluctuates less, which can ensure the stability of the instrument during use.

[0056] This invention incorporates damping fluid within the mounting cavity, which dampens the ball, slowing down the movement of the ball head 301 within the mounting cavity and facilitating the user to adjust the mounting base 2 of the instrument to a suitable position.

[0057] In one embodiment, such as Figure 2 As shown, the mounting base 2 has slots 202 on both sides, which are suitable for detachable engagement with the buckles on the instrument.

[0058] Specifically, in this embodiment, the mounting base 2 is provided with symmetrical slots 202 on both sides, and the slots 202 match the buckles protruding from the back of the instrument.

[0059] The slot 202 of this utility model can limit the buckle on the instrument, making the instrument more securely installed on the mounting base 2.

[0060] According to an embodiment of the present invention, another aspect provides an instrument, including a body, a connecting wire, a probe, and the aforementioned instrument fixing device. The body has a chip inside and a mounting groove at the bottom. One end of the connecting wire is connected to the body, and the probe is connected to the end of the connecting wire away from the body. The mounting base 2 is detachably installed in the mounting groove.

[0061] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
