Description

Technical Field

[0001] This utility model belongs to the field of control cabinet installation technology, and more specifically, it relates to a PLC control cabinet base with vibration buffering function. Background Technology

[0002] A PLC control cabinet is a programmable control cabinet. A control cabinet refers to a complete set of control cabinets, which are electrical cabinets that can control motors and switches. PLC control cabinets have protection functions such as overload, short circuit, and phase loss protection. When a PLC control cabinet is needed, it needs to be installed in an indoor location. In some environments, a base is added to the bottom of the control cabinet for fixation.

[0003] Based on the above, the following problems were found: Although some existing control cabinet bases have some shock absorption and buffering functions, the shock absorption method is singular, and it can only reduce vibration in the vertical direction. However, the control cabinet will vibrate not only in the vertical direction during use. In addition, the existing bases are connected to each other, which makes it impossible for the control cabinets to be close together. This not only occupies space, but also makes it difficult to connect adjacent control cabinets.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a PLC control cabinet base with vibration buffering function to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a PLC control cabinet base with vibration buffering function, which solves the problem that the current vibration reduction method is only limited to vertical vibration reduction and that the control cabinets cannot be brought together due to the interconnection between bases.

[0006] This utility model provides a PLC control cabinet base with vibration buffering function, which is achieved by the following specific technical means:

[0007] A PLC control cabinet base with vibration damping function includes a base and a support plate. Guide rails are fixed on both sides of the inner wall of the base. First sliders are slidably connected to both ends of the two guide rails. Springs are fixed to both ends of the four first sliders near the inner wall of the base. First support rods are fixed in the middle of the two first sliders located in the same vertical plane. Second sliders are movably sleeved at both ends of the two first support rods. First hinge seats are fixed to the top of the four second sliders. Second support rods are hinged to the top of the four first hinge seats. Second hinge seats are fixed on both sides of the middle part of the bottom of the support plate. The tops of the two second support rods located in the same vertical plane are hinged to the second hinge seats. Tension springs are movably sleeved in the middle of the outer wall of the two first support rods.

[0008] Furthermore, the two ends of the tension spring are respectively fixed to the two second sliders, and the four springs are respectively fixed to the two ends of the inner wall of the base.

[0009] Furthermore, each of the second sliders is rotatably connected to a roller at its bottom, and the roller abuts against the bottom of the inner wall of the base.

[0010] Furthermore, the length and width of the support plate are both greater than the length and width of the outer wall of the base.

[0011] Furthermore, each end of both sides of the base is fixed with a sleeve block, and each of the four sleeve blocks is movably fitted with a lifting wheel. The bottom of the sleeve block and the bottom of the base are on the same horizontal plane.

[0012] Furthermore, a connecting block is fixed to the middle of both sides of the base, and a first threaded rod is rotatably connected to the top of each of the two connecting blocks. A connecting rod is threaded to the outer wall of each of the two first threaded rods. The connecting rod is U-shaped, and the bottom ends of the two connecting rods are respectively fixed to the tops of the four lifting wheels.

[0013] Furthermore, a second threaded rod is fixed on both sides of the middle part of one side of the base, and a threaded sleeve rod is rotatably connected on both sides of the middle part of the other side of the base. The two threaded sleeve rods are used in conjunction with the two second threaded rods respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the control cabinet is placed on top of the support plate, the support plate moves downward, the two second sliders move to the sides, and the tension springs are stretched. When the control cabinet moves up and down, the tension springs extend and retract to buffer the movement. The four first sliders are connected by four springs. When the control cabinet moves horizontally, the tension springs stretch and move horizontally as a whole to cooperate. When the control cabinet moves horizontally and vertically, the four springs cooperate to compress and stretch, thereby achieving multi-directional shock absorption and making installation very convenient.

[0016] 2. In this utility model, two threaded sleeves are used in conjunction with two second threaded rods respectively. By connecting the threaded sleeve of one base with the second threaded rod of the other base, the two bases are connected. The length and width of the support plate are greater than the length and width of the outer wall of the base, so that the base occupies a small area and will not affect the interconnection of the control cabinets on the top of the support plate. This allows adjacent control cabinets to be close together, and the interconnection between the bases forms a whole for multiple control cabinets. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a PLC control cabinet base with vibration buffering function, including a base 1 and a support plate 11. Guide rails 2 are fixed on both sides of the inner wall of the base 1. First sliders 3 are slidably connected to both ends of the two guide rails 2. Springs 4 are fixed to both ends of the four first sliders 3 near the inner wall of the base 1. First support rods 5 are fixed in the middle of the two first sliders 3 located on the same vertical plane. Second sliders 6 are movably sleeved at both ends of the two first support rods 5. First hinge seats 8 are fixed to the top of the four second sliders 6. Second support rods 9 are hinged to the top of the four first hinge seats 8. Second hinge seats 10 are fixed on both sides of the middle part of the bottom of the support plate 11. The tops of the two second support rods 9 located on the same vertical plane are hinged to the second hinge seats 10. Tension springs 7 are movably sleeved in the middle of the outer wall of the two first support rods 5.

[0028] The tension spring 7 is fixed at both ends to the two second sliders 6, and the four springs 4 are fixed at both ends to the inner wall of the base 1. The tension spring 7 pulls the two second sliders 6 closer to the center, making the included angle between the two second support rods 9 smaller, which drives the first hinge seat 8 and the support plate 11 to move upward. When the control cabinet is placed on top of the support plate 11, the support plate 11 moves downward, the two second sliders 6 move to both sides, and the tension spring 7 is stretched. When the control cabinet moves up and down, the tension spring 7 expands and contracts to buffer the movement. The four springs 4 connect the four first sliders 3. When the control cabinet moves horizontally, the tension spring 7 stretches and moves horizontally to cooperate. When the control cabinet moves horizontally and vertically, the four springs 4 cooperate to compress and stretch.

[0029] Each of the second sliders 6 has a roller rotatably connected to its bottom. The roller abuts against the bottom of the inner wall of the base 1. When the second slider 6 moves laterally left and right, the second slider 6 moves laterally better inside the base 1 through the roller.

[0030] The length and width of the support plate 11 are both greater than the length and width of the outer wall of the base 1, which makes the base 1 occupy a small area and will not affect the interconnection of the control cabinets on the top of the support plate 11.

[0031] The base 1 has two fixed sleeve blocks 12 on both sides. Each of the four sleeve blocks 12 has a lifting wheel 13 movably connected inside. The bottom of the sleeve block 12 is on the same horizontal plane as the bottom of the base 1. The lifting wheel 13 supports the base 1 and drives the base 1 and the control cabinet on the top to move.

[0032] The base 1 has connecting blocks 15 fixed in the middle of both sides. The top of each connecting block 15 is rotatably connected to a first threaded rod 16. The outer walls of the two first threaded rods 16 are threaded with connecting rods 14. The connecting rods 14 are U-shaped. The bottom ends of the two connecting rods 14 are fixed to the tops of the four lifting wheels 13 respectively. After the base 1 and the control cabinet are moved to the fixed position, the connecting rods 14 are moved upward by rotating the first threaded rods 16, so that the lifting wheels 13 are retracted into the sleeve block 12.

[0033] Among them, the middle of one side of the base 1 is fixed with two second threaded rods 18, and the middle of the other side of the base 1 is rotatably connected with two threaded sleeves 17. The two threaded sleeves 17 are used in conjunction with the two second threaded rods 18 respectively. By connecting the threaded sleeve 17 of one base 1 with the second threaded rod 18 of the other base, the two bases 1 are connected.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the control cabinet is first placed on top of the support plate 11. The length and width of the support plate 11 are both greater than the length and width of the outer wall of the base 1, so that the base 1 occupies a small area and will not affect the interconnection of the control cabinets on top of the support plate 11. Then, the base 1 is supported by the lifting wheel 13, which moves the base 1 and the control cabinet on top. After the base 1 and the control cabinet move to a fixed position, the connecting rod 14 is moved upward by rotating the first threaded rod 16, and the lifting wheel 13 is retracted into the sleeve block 12. 17 is connected to the second threaded rod 18 of another base, thereby connecting the two bases 1. In use, when the control cabinet is placed on top of the support plate 11, the support plate 11 moves downward, the two second sliders 6 move to the sides, and the tension spring 7 is stretched. When the control cabinet moves up and down, the tension spring 7 expands and contracts to buffer the movement. The four first sliders 3 are connected by four springs 4. When the control cabinet moves horizontally, the tension spring 7 stretches and moves horizontally as a whole to cooperate. When the control cabinet moves horizontally and vertically, the four springs 4 cooperate to compress and stretch, thereby achieving vibration buffering function in multiple directions.
