[0026] The present utility model will be further described below in conjunction with the embodiments.

[0027] Please refer to Figures 1-6, the present utility model provides a multi-channel data collector, including a housing 3. Inside the housing 3, a circuit board 6 is provided. On the inner sidewall of the housing 3, there are support plates b7 and support blocks 9 located on two sides parallel to the circuit board 6. The support blocks 9 are fixed on the inner sidewall of the housing 3. On the side of the support plate b7 facing the support block 9, there is a support plate b8 with a top surface flush with the top surface of the support block 9. Inside the housing 3, there is a limiting component 1 that cooperates with the support plate b8 and the support block 9 to clamp the circuit board 6. At the bottom of the limiting component 1 and the bottom of the support plate b7, there are both distance-adjusting components 2; when installing the circuit board 6 inside the housing 3, place the circuit board 6 flat and place it on the top surfaces of the support plate b8 and the support block 9. The two ends of the circuit board 6 are supported by the support plate b8 and the support block 9. The other two ends of the circuit board 6 are supported by the two limiting components 1, and the two ends of the circuit board 6 are symmetrically limited by the two limiting components 1, so as to realize the clamping of the circuit board 6 inside the housing 3. When it is necessary to remove the circuit board 6, the limit on the circuit board 6 is released by the limiting component 1, and the circuit board 6 can be conveniently removed, effectively improving the installation and removal efficiency of the circuit board 6, making the installation and removal of the circuit board 6 inside the housing 3 more convenient, facilitating subsequent maintenance, improving the later maintenance efficiency, saving the operation of repeatedly installing and removing multiple screws, saving the installation and removal workload, and avoiding the problem that the screws are prone to slipping teeth due to repeated installation and removal; through the support of the circuit board 6 by the support plate b8, the support block 9 and the two limiting components 1, the circuit board 6 is suspended inside the housing 3, thus avoiding the side of the circuit board 6 from fitting with the inner sidewall of the housing 3, effectively increasing the gap between the circuit board 6 and the inner sidewall of the housing 3, enabling the heat on the circuit board 6 to be dissipated more comprehensively, effectively improving the overall heat dissipation efficiency of the circuit board 6, and prolonging the overall service life; by setting the distance-adjusting component 2, the distance between the support plate b8, the support block 9 and the two limiting components 1 can be conveniently adjusted, so as to adapt to the installation of circuit boards 6 of different sizes, effectively increasing the overall applicable range and improving the overall practicality.

[0028] Further, as Figure 2 , Figure 4 and Figure 6As shown in the figure, it is worth specifically explaining that the blocking component 1 includes an L-shaped support plate 101. There are two L-shaped support plates 101, and the two L-shaped support plates 101 are distributed on the two sides parallel to the circuit board 6. A support plate a104 flush with the support plate b8 is fixed on the side surface of the L-shaped support plate 101. A support plate a105 is fixed at the top of the L-shaped support plate 101. A slide bar 107 with a rectangular cross-section is slidably penetrated through the support plate a105. A triangular stopper 102 is fixed at one end of the slide bar 107 facing the center of the circuit board 6. A spring 103 is sleeved on the side surface of the slide bar 107, and the two ends of the spring 103 are respectively abutted against the side surface of the support plate a105 and the side surface of the triangular stopper 102; Place the circuit board 6 between the support plate b8, the support block 9 and the two L-shaped support plates 101 and press down the circuit board 6, so that the two ends of the circuit board 6 press the triangular stopper 102, causing the triangular stopper 102 to retract, so that the two ends of the circuit board 6 cross over the triangular stopper 102 and are clamped between the support plate a104 and the triangular stopper 102. The spring 103 pushes the triangular stopper 102 to automatically extend to stop and limit the circuit board 6, thus realizing the clamping of the circuit board 6 inside the housing 3. When the circuit board 6 needs to be removed, by pulling the triangular stopper 102, the limit of the triangular stopper 102 on the circuit board 6 is released, and the circuit board 6 can be conveniently removed, effectively improving the installation and removal efficiency of the circuit board 6, making the installation and removal of the circuit board 6 inside the housing 3 more convenient, facilitating subsequent maintenance, improving the later maintenance efficiency, saving the operation of repeatedly installing and removing multiple screws, saving the installation and removal workload, and avoiding the problem that the screws are easily stripped due to repeated installation and removal. The circuit board 6 is supported by the support plate b8, the support block 9 and the two support plates a104, so that the circuit board 6 is suspended inside the housing 3, thus avoiding the side surface of the circuit board 6 from fitting with the inner side wall of the housing 3, effectively increasing the gap between the circuit board 6 and the inner side wall of the housing 3, enabling the heat on the circuit board 6 to be dissipated more comprehensively, effectively improving the overall heat dissipation efficiency of the circuit board 6, and prolonging the overall service life.

[0029] Further, as Figure 4 and Figure 6 shown, it is worth specifically explaining that a joint plate 106 is fixed at the end of the slide bar 107 away from the triangular stopper 102, and the joint plate 106 is located on the side of the support plate a105 away from the triangular stopper 102; During specific operation, the set joint plate 106 prevents the slide bar 107 from coming out while facilitating the pulling of the slide bar 107 through the set joint plate 106, thereby pulling the triangular stopper 102 to move and facilitating the release of the limit of the triangular stopper 102 on the circuit board 6.

[0030] Further, as Figure 2 、 Figure 3 、 Figure 5 andFigure 6 As shown, it is worth specifically explaining that the distance adjustment component 2 includes a sliding sleeve plate 202 fixed to the inner side wall of the housing 3. One L-shaped support plate 101 is fixed to the inner side wall of the housing 3, and the other L-shaped support plate 101 and the support plate b7 are both slidably arranged in contact with the inner side wall of the housing 3. The bottom ends of the L-shaped support plate 101 and the support plate b7 that are in contact with and slide along the inner side wall of the housing 3 are both fixed with sliding plates 201 that penetrate through the sliding sleeve plate 202. A locking bolt 203 is threadedly connected to the side surface of the sliding sleeve plate 202, and the screw end of the locking bolt 203 contacts the side surface of the sliding plate 201. During specific operation, by loosening and tightening the locking bolt 203, the sliding plate 201 can slide and adjust within the sliding sleeve plate 202, thereby adjusting the positions of the support plate b7 and one of the L-shaped support plates 101, so as to adapt to the installation of circuit boards 6 of different sizes, effectively improving the overall applicable range and overall practicality.

[0031] This solution has the following working process: When installing the circuit board 6 in the housing 3, place the circuit board 6 flat, place the circuit board 6 between the support plate b8, the support block 9 and the two L-shaped support plates 101 and press down the circuit board 6, so that the two ends of the circuit board 6 press the triangular stoppers 102, causing the triangular stoppers 102 to retract, so that the two ends of the circuit board 6 can cross over the triangular stoppers 102 and be caught between the support plate a104 and the triangular stoppers 102. Then, the spring 103 pushes the triangular stoppers 102 to automatically extend to stop and limit the circuit board 6, thereby realizing the clamping of the circuit board 6 inside the housing 3. When it is necessary to remove the circuit board 6, by pulling the triangular stoppers 102 to release the limit of the triangular stoppers 102 on the circuit board 6, the circuit board 6 can be removed. The circuit board 6 is supported by the support plate b8, the support block 9 and the two support plates a104, so that the circuit board 6 is suspended inside the housing 3, avoiding the side surface of the circuit board 6 from being in contact with the inner side wall of the housing 3. When installing circuit boards of different sizes, by loosening and tightening the locking bolt 203, the sliding plate 201 can slide and adjust within the sliding sleeve plate 202, thereby adjusting the positions of the support plate b7 and one of the L-shaped support plates 101, so as to adapt to the installation of circuit boards 6 of different sizes.

[0032] Furthermore, as shown in Figure 1 and Figure 2 it is worth specifically explaining that ventilation holes 10 are provided on the side wall of the housing 3. There are multiple ventilation holes 10 and the multiple ventilation holes 10 are equally spaced. During specific operation, the heat inside the housing 3 is discharged through the multiple ventilation holes 10, which is combined with the suspended placement design of the circuit board 6 to improve the overall heat dissipation efficiency of the housing 3.

[0033] Furthermore, as shown in Figure 1 and Figure 2As shown, it is worth specifically stating that a handle 4 is fixed on the outer side wall of the outer shell 3, and a cover plate 5 is fixed on the opening end of the outer shell 3 through a plurality of screws; during specific operation, the interior of the outer shell 3 can be conveniently overhauled by removing the cover plate 5.

[0034] In summary: The two ends of the circuit board 6 are supported by the support plate b8 and the support block 9, the other two ends of the circuit board 6 are supported by two groups of limiting components 1, and the two ends of the circuit board 6 are symmetrically limited by the two groups of limiting components 1, so as to realize the clamping of the circuit board 6 inside the outer shell 3. When the circuit board 6 needs to be removed, the limit on the circuit board 6 is released by the limiting component 1, and the circuit board 6 can be conveniently removed, effectively improving the installation and removal efficiency of the circuit board 6, making the installation and removal of the circuit board 6 inside the outer shell 3 more convenient, facilitating subsequent maintenance, improving the later maintenance efficiency, eliminating the operation of repeatedly installing and removing multiple screws, saving the installation and removal workload, and avoiding the problem that the screws are prone to slipping due to repeated installation and removal; through the support of the circuit board 6 by the support plate b8, the support block 9 and the two groups of limiting components 1, the circuit board 6 is placed in suspension inside the outer shell 3, thus preventing the side surface of the circuit board 6 from contacting the inner side wall of the outer shell 3, effectively increasing the gap between the circuit board 6 and the inner side wall of the outer shell 3, enabling the heat on the circuit board 6 to be dissipated more comprehensively, effectively improving the overall heat dissipation efficiency of the circuit board 6, and prolonging the overall service life; through the provided distance adjusting component 2, the distance between the support plate b8, the support block 9 and the two groups of limiting components 1 can be conveniently adjusted, so as to adapt to the installation of circuit boards 6 of different sizes, effectively increasing the overall applicable range and improving the overall practicality.
