[0030] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0031] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0032] like Figure 1 As shown, a silicon photocell detection fixture with a limiting function in this embodiment includes a base 100, a support plate 110 is provided on the upper end surface of the base 100, a detection plate 120 is provided on the base 100 and located on the front side of the support plate 110, a lifting rod 121 is provided on the upper end surface of the detection plate 120, and a lifting component for driving the lifting rod 121 to lift and lower is provided on the support plate 110, a mounting groove 131 with an open end is provided on the upper end surface of the base 100 along its extension direction, and a limiting groove 201 is provided on the side wall opposite to the mounting groove 131 along its extension direction, a slidable moving block 140 is provided on the base 100, and a mounting block 141 extending into the mounting groove 131 is provided on the moving block 140, and a limiting block 142 inserted into the corresponding limiting groove 201 is provided on the side wall opposite to the mounting block 141, and a positioning component for positioning the position of the moving block 140 after movement is provided in the mounting block 141.

[0033] In this embodiment, the lifting rod 121 is fixedly mounted on the detection plate 120, and the support plate 110 is fixedly mounted on the base 100, so that the lifting rod 121 can be driven by the lifting assembly on the support plate 110 to drive the detection plate 120 to move up and down. When the detection plate 120 rises, the silicon photocell is placed on the upper end surface of the base 100 below the detection plate 120. At this time, one side of the silicon photocell abuts against the front side of the support plate 110, and the moving block 140 is driven to move along the mounting groove 131, so that The moving block 140 can abut against the other side of the silicon photocell. At this time, the moving block 140 is positioned by the positioning assembly so that the moving block 140 can always maintain abutment against the silicon photocell, thereby achieving fixed installation on the base 100 at the lower side of the detection plate 120, that is, the silicon photocell is limited on the base 100. At this time, the lifting rod 121 is driven downward by the lifting assembly so that the lower end surface of the detection plate 120 can abut against the upper end surface of the silicon photocell to detect the silicon photocell;

[0034] In actual use, a light source is installed on the upper end surface of the base 100, and the silicon photocell converts light energy into electrical energy through the light source. The electrical energy generated by the silicon photocell is detected by the detection board 120. A display 180 is also installed on the base 100, so that the detection information of the silicon photocell by the detection board 120 can be displayed through the display 180;

[0035] Among them, the detection board 120, the light source and the display 180 all adopt the structure disclosed in the patent with publication number CN212845738U in the background technology;

[0036] The moving block 140, the mounting block 141 and the limiting block 142 are all fixedly connected. When the moving block 140 moves, it can drive the mounting block 141 and the limiting block 142 to slide in the corresponding mounting groove 131 and the limiting groove 201, so that when the mounting block 141 is positioned by the positioning assembly, the position of the moving block 140 is positioned;

[0037] The side wall of the limiting block 142 fits with the side wall of the limiting groove 201, so that the limiting block 142 can only slide stably along the limiting groove 201, so that the moving block 140 can better abut the silicon photocell;

[0038] Among them, by the two limiting blocks 142 being stuck in the corresponding limiting grooves 201, it is possible to prevent the mounting block 141 from sliding out of the mounting groove 131, thereby affecting the positioning of the silicon photocell by the moving block 140;

[0039] Among them, limiting rods 170 penetrating the detection plate 120 are fixedly installed on the base 100 and at the two ends of the detection plate 120. The detection plate 120 is limited by the two limiting rods 170, so that the detection plate 120 can only be stably lifted and lowered along the limiting rods 170, thereby improving the stable lifting effect of the detection plate 120. At the same time, the two limiting rods 170 can also limit the two sides of the silicon photocell placed under the detection plate 120, thereby preventing the silicon photocell from shaking left and right when the silicon detection plate 120 detects the silicon photocell, thereby affecting the detection effect of the detection plate 120 on the silicon photocell;

[0040] Among them, the position of the moving block 140 after movement is positioned by the positioning component, so that the support plate 110 and the moving block 140 can better limit the two sides of the silicon photocell. Compared with the existing ones, this silicon photocell detection fixture with a limiting function can prevent the silicon photocell from sliding on the base 100 when the detection board 120 detects the silicon photocell, causing the silicon photocell to shake and shift, thereby affecting the detection effect of the detection board 120 on the silicon photocell. It is more practical in actual use.

[0041] like Figure 1-3As shown, in this embodiment, the lifting assembly includes a fixed block 150 arranged on the upper end surface of the support plate 110, and a fixed groove 151 is arranged on the upper end surface of the fixed block 150, and the fixed groove 151 is opened at both ends. A rotating plate 152 with one end extending into the fixed groove 151 and being rotatable is provided on the support plate 110, and a hinged plate 153 is provided between the rotating plate 152 and the lifting rod 121, and the two ends of the hinged plate 153 are respectively hingedly mounted on the corresponding rotating plate 152 and the lifting rod 121, and the rotating plate 152 rotates to drive the lifting rod 121 to move up and down.

[0042] In this embodiment, by setting the fixed block 150, the fixed slot 151, the rotating plate 152 and the hinged plate 153, the rotating plate 152 can drive the hinged plate 153 to move up and down, thereby driving the lifting rod 121 to move up and down, that is, the detection plate 120 to move up and down;

[0043] The fixed block 150 is fixedly mounted on the support plate 110, and a plug rod penetrating one end of the rotating plate 152 is mounted on the side wall of the fixed block 150. The plug rod and the fixed block 150 are threadedly matched, so that one end of the rotating plate 152 is rotatably mounted on the fixed block 150, that is, one end of the rotating plate 152 is hingedly connected to the fixed block 150, and the two ends of the hinged plate 153 are respectively hingedly connected to the lower end of the lifting rod 121 and the rotating plate 152, so that in actual use, the rotating plate 152 rotates around one end thereof to drive the hinged plate 153 to pull the lifting rod 121 to be lifted or lowered;

[0044] In order to achieve the smooth lifting and lowering of the detection plate 120 by the lifting rod 121, a positioning plate 160 is fixedly installed on the front side of the support plate 110, and a through plate 161 for the lifting rod 121 to penetrate is fixedly installed on the positioning plate 160. The lifting rod 121 is limited by the through plate 161, so that the lifting effect of the lifting rod 121 is better, thereby better driving the detection plate 120 to be lifted and lowered;

[0045] During actual use, a handle 154 for driving the rotating plate 152 to rotate is fixedly mounted on the side wall of the rotating plate 152. The handle 154 can better drive the rotating plate 152 to rotate around one end, making it easier for users to operate.

[0046] like Figure 1-3 As shown, in this embodiment, a hinge groove 301 is provided on the upper end surface of the hinge plate 153 for the lower end of the rotating plate 152 to be inserted, and openings are set on both sides of the hinge groove 301. A first screw 310 with a thread penetrating the rotating plate 152 is provided on the side wall of the hinge plate 153. A groove 321 is provided on the upper end surface of the lifting rod 121, and openings are set on both sides of the groove 321. A mounting portion 302 extending outwardly from the lower end surface of the hinge plate 153 is formed to be inserted into the groove 321, and a second screw 330 penetrating the mounting portion 302 is provided on the lifting rod 121.

[0047] In this embodiment, by setting the hinge groove 301, the first screw 310, the groove 321, the mounting portion 302 and the second screw 330, the lower end of the rotating plate 152 is extended into the groove 321, and the first screw 310 penetrates the rotating plate 152, thereby realizing the hinged connection of the other end of the rotating plate 152 at the upper end of the hinge plate 153, and then the mounting portion 302 at the lower end of the hinge plate 153 is inserted into the groove 321, and the second screw 330 threadably penetrates the groove 321 and the mounting portion 302, so as to realize the hinged connection between the hinge plate 153 and the lifting rod 121. Through the above structure, the hinged installation of the two ends of the hinge plate 153 on the rotating plate 152 and the lifting rod 121 is realized, so that when the rotating plate 152 is driven to rotate by the handle 154, the lifting rod 121 driven by the hinge plate 153 is lifted and lowered.

[0048] like Figure 1-6 As shown, in this embodiment, a plurality of positioning holes 202 are provided on the opposite side walls of the two limiting grooves 201 along their extending direction, a mounting cavity 401 is provided in the mounting block 141, and a connecting cavity 402 connected to the mounting cavity 401 is provided in the limiting block 142;

[0049] The positioning assembly includes a slider 500 which is relatively arranged in the connecting cavity 402 and can slide. A positioning rod 501 with one end extending out of the limit block 142 is provided on the side wall of the slider 500. A spring 510 is sleeved on the positioning rod 501. The spring 510 is used to push the two limit blocks 142 closer to each other. A first inclined surface 601 is provided at one end of the slider 500. A liftable driving block 520 is provided in the installation cavity 401. Second inclined surfaces 611 matching the corresponding first inclined surfaces 601 are provided at both ends of the driving block 520. The driving block 520 moves down the second inclined surface 611 to squeeze the corresponding first inclined surface 601, so that the two sliders 500 are moved away from each other, and one end of the positioning rod 501 is inserted into the corresponding positioning hole 202.

[0050] In this embodiment, by setting the positioning hole 202, the installation cavity 401, the connecting cavity 402, the slider 500, the positioning rod 501, the spring 510, the first inclined surface 601, the driving block 520 and the second inclined surface 611, the driving block 520 moves downward, so that the second inclined surface 611 on the driving block 520 presses the corresponding first inclined surface 601, so that the two sliders 500 are separated from each other, and the spring 510 is pressed, and the positioning rod 501 on the slider 500 is inserted into the corresponding positioning hole 202, so as to realize the positioning of the position of the installation block 141, that is, the moving block 140 is positioned;

[0051] When the driving block 520 moves upward, the second inclined surface 611 on the driving block 520 releases the compression on the first inclined surface 601 on the slider 500. At this time, the spring 510 is released from compression, pushing the corresponding sliders 500 closer to each other, so that the positioning rod 501 is disengaged from the corresponding positioning hole 202, thereby releasing the positioning of the mounting block 141, that is, the moving block 140 can continue to move;

[0052] The side wall of the driving block 520 fits with the side wall of the installation cavity 401, so that the driving block 520 can only slide relatively stably along the installation cavity 401, thereby better driving the two sliders 500 away from each other;

[0053] Among them, the side wall of the slider 500 fits with the side wall of the connecting cavity 402, so that the slider 500 can only slide relatively stably along the connecting cavity, thereby avoiding the slider 500 from shaking when moving in the connecting cavity 402, causing the positioning rod 501 to be unable to be better inserted into the corresponding positioning hole 202, affecting the positioning effect of the mounting block 141.

[0054] like Figure 1-6 As shown, in this embodiment, a rotatable bolt 530 is provided on the upper end surface of the driving block 520 , and the upper end of the bolt 530 is threadedly penetrated through the upper end surface of the mounting block 141 .

[0055] In this embodiment, the bolt 530 is provided so that the bolt 530 and the upper end surface of the mounting block 141 are threadedly matched, so that the rotation of the bolt 530 can drive the driving block 520 to be raised and lowered, and at the same time, the driving block 520 can maintain the position after the movement, that is, the positioning rod 501 can always be inserted into the corresponding positioning hole 202 for positioning;

[0056] The bolt 530 is installed on the driving block 520 through the bearing seat, so that the driving block 520 does not rotate when the bolt 530 rotates. At the same time, the lifting of the bolt 530 can drive the driving block 520 to lift;

[0057] When it is actually used, a hand-cranked wheel 531 is installed on the upper end surface of the bolt 530, and the hand-cranked wheel 531 can better drive the bolt 530 to rotate, which is more convenient to use.

[0058] Working principle: First, lift the handle 154 to move the detection plate 120 upward, and then place the silicon photocell on the base 100 and between the two limit rods 170. At this time, push the moving block 140 to limit the silicon photocell through the moving block 140 and the support plate 110. Turn on the light source and press the handle 154 to make the detection plate 120 abut against the silicon photocell. At this time, the detection board 120 detects the silicon photocell, and the detection board 120 displays the detection data on the silicon photocell through the display 180.

[0059] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
