[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] As attached Figures 1 to 4The circuit board cage rack shown includes a longitudinal mounting frame 1, a bottom limiting rod 3, a vertical mounting frame 4, a back limiting rod 6, a side limiting rod 7, and an adjustable load-bearing plate 10. The longitudinal mounting frame 1 is provided in two sets, serving as the main support structure of the cage rack and bearing the weight of other components and the circuit board. The vertical mounting frame 4 is located on the upper surface of the longitudinal mounting frame 1, providing installation positions for the device components. Load-bearing rods 2 are welded to the opposite surfaces of the two sets of longitudinal mounting frames 1, connecting the two sets of longitudinal mounting frames 1 and bearing the weight of the circuit board, enhancing the overall load-bearing capacity of the cage rack and enabling the cage rack to stably place the circuit board. The bottom limiting rod 3 is located at the upper end of the load-bearing rod 2, limiting the bottom edge of the circuit board to prevent it from slipping off the bottom during placement, thus playing a preliminary positioning and fixing role.

[0027] A fixing plate 5 is welded to the bottom of the front end of the vertical mounting frame 4. The fixing plate 5 supports and fixes the bottom of the vertical mounting frame 4. The back limiting rod 6 is welded to the front end of the vertical mounting frame 4. The side limiting rod 7 is set above the bottom limiting rod 3 to limit the back of the circuit board. The side limiting rod 7 works together with the bottom limiting rod 3 and the side limiting rod 7 to confine the circuit board in a specific space, preventing the circuit board from shaking or shifting on the frame. The inner cavity of the front end of the two sets of longitudinal mounting frames 1 is embedded with telescopic rods 9. The adjustable load-bearing plate 10 is fixedly installed on the front end face of the two sets of telescopic rods 9. The telescopic rods 9 are in the inner cavity of the front end of the two sets of longitudinal mounting frames 1 and can be extended and retracted as needed. By adjusting the length of the telescopic rods 9, the position of the adjustable load-bearing plate 10 can be changed, and the load-bearing plate 10 is adjusted to place the front end of the circuit board, sharing the weight of the circuit board with the device. Its position can be adjusted by the telescopic rods 9, which can provide a suitable support point for the circuit board and ensure that the circuit board remains balanced when placed.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, several sets of bottom limiting rods 3, back limiting rods 6, and side limiting rods 7 are provided. The number of bottom limiting rods 3, back limiting rods 6, and side limiting rods 7 in these sets is the same. The bottom limiting rods 3, back limiting rods 6, and side limiting rods 7 are all distributed at equal intervals. The multiple sets of bottom limiting rods 3, back limiting rods 6, and side limiting rods 7, which are distributed at equal intervals, can limit and support the circuit board at multiple positions. Two sets of load-bearing rods 2 are provided. The two ends of the other set of load-bearing rods 2 abut against the opposite surfaces of the rear ends of the two sets of longitudinal mounting brackets 1, and the two sets of load-bearing rods 2 jointly bear the weight of the circuit board.

[0031] In a preferred embodiment, the side limiting rods 7 are arc-shaped, and arc-shaped silicone pads 8 are installed on the opposite surfaces of every two sets of side limiting rods 7. The side limiting rods 7, together with the arc-shaped silicone pads 8, support the sides of the circuit board and prevent the circuit board from shaking excessively. The bottom of the back limiting rod 6 abuts against the upper surface of the fixing plate 5 and is welded. The two ends of each set of side limiting rods 7 abut against one side of the opposite surface of the bottom limiting rod 3 and the back limiting rod 6 and are welded. The bottom of the back limiting rod 6 is welded to the fixing plate 5, and the two ends of the side limiting rods 7 are welded to the bottom limiting rod 3 and the back limiting rod 6, respectively. This makes the various components of the pig cage frame form a tight integral structure. Through welding, force and torque can be effectively transmitted, making the entire pig cage frame structure more stable.

[0032] In a preferred embodiment, a strip silicone pad 11 is installed on the upper surface of the adjustable load-bearing plate 10. The strip silicone pad 11 on the adjustable load-bearing plate 10 can prevent the circuit board from directly contacting the adjustable load-bearing plate 10 and prevent the surface of the circuit board from being scratched. The strip silicone pad 11 is linked to the adjustable load-bearing plate 10 and the load-bearing rod 2 to correspond to the same horizontal line. Being on the same horizontal line can ensure that the circuit board can obtain uniform support force when placed, and avoid the circuit board deformation due to uneven force.

[0033] As a preferred embodiment, movable handles 12 are provided at the rear of both ends of the vertical mounting frame 4. The two sets of movable handles 12 are symmetrically arranged, providing operators with convenient gripping positions, allowing operators to hold the frame with both hands, apply force more evenly, and facilitate pushing or pulling the pig cage frame.

[0034] In a preferred embodiment, casters 13 are installed at both ends of the bottom of the two sets of longitudinal mounting frames 1, and auxiliary guide wheels 14 are installed at both ends of the bottom of the adjusting load-bearing plate 10. The casters 13 are installed at both ends of the bottom of the two sets of longitudinal mounting frames 1, so that the pig cage frame can move easily on the ground and can flexibly change the direction of movement, which is convenient for transporting circuit boards between different work areas. The auxiliary guide wheels 14 are used in conjunction with the casters 13 to help share the weight of the circuit boards on the adjusting load-bearing plate 10.

[0035] The working process of this utility model is as follows: First, two sets of longitudinal mounting frames 1 serve as the main support structure, bearing the weight of the entire pig cage frame and the circuit board. The circuit board is placed on the pig cage frame. The bottom limiting rod 3 initially positions and fixes the bottom edge of the circuit board to prevent it from slipping off the bottom. The side limiting rod 7 and the back limiting rod 6 restrict the circuit board within a specific space. Through multiple sets of equally spaced bottom limiting rods 3, back limiting rods 6 and side limiting rods 7, the circuit board is limited and supported at multiple positions. The two sets of load-bearing rods 2 are horizontally connected to the longitudinal mounting frames 1 and are adjusted together with the load-bearing plate 10 through the telescopic rod 9 to form a load-bearing platform that can adapt to different circuit board sizes.

[0036] Specifically, a three-dimensional limiting network is formed by the bottom limiting rod 3, the back limiting rod 6, and the side limiting rod 7. When placing the circuit board, the bottom limiting rod 3 first positions the bottom edge of the circuit board. Subsequently, the back limiting rod 6 and the side limiting rod 7 restrict the movement of the circuit board from the other two directions. The arc-shaped side limiting rod 7 conforms to the side contour of the circuit board, and together with the arc-shaped silicone pad 8, it increases friction and reduces shaking. The strip silicone pad 11 on the load-bearing plate 10 is adjusted to keep it at the same horizontal line as the load-bearing rod 2, providing uniform support and preventing the circuit board from deforming under stress, thus achieving the goal of controlling the circuit board. The plate is fixed, while the casters 13 at the bottom of the longitudinal mounting frame 1 give the pig cage rack flexible movement ability. The operator can easily push the pig cage rack to move on the workshop floor and turn in any direction through the casters 13. Adjusting the auxiliary guide wheels 14 at the bottom of the load-bearing plate 10 to share the weight reduces the force on the casters 13 and ensures smooth movement. The symmetrically arranged moving handles 12 at the rear of the vertical mounting frame 4 provide operators with comfortable grip points, making it easy to control the movement of the pig cage rack with both hands. The above is the working principle of this convenient circuit board pig cage rack.
