[0028] Reference example Figures 1 to 6 A blocking device for a JP cabinet comprises a cabinet body 1, wherein the cabinet body 1 is provided with a plurality of blocking devices 2, wherein the blocking device 2 comprises a supporting frame 3, a threading column 4, and a fastening nut 5, wherein the threading column 4 is arranged in the supporting frame 3, wherein a plurality of through holes 31 are evenly distributed on the side wall of the supporting frame 3 with a dot as the axis, wherein the through holes 31 are provided with a guide portion 32, and the fastening nut 5 is provided with a clamping portion 51 corresponding to the through hole 31 and abutting against the outer wall of the threading column 4, wherein when the fastening nut 5 rotates, the clamping portion 51 is pressed toward the center point of the threading column 4 along the trajectory of the guide portion 32;

[0029] It is worth mentioning that a partition 11 is provided in the cabinet 1 to form a first concave cavity 12 and a second concave cavity 13. A first wire hole 14 is provided at the bottom of the first concave cavity 12, and a plurality of second wire holes 15 are provided at the bottom of the second concave cavity 13. The partition 11 divides the space in the cabinet 1 into two. Different electrical equipment can be installed in the first concave cavity 12 and the second concave cavity 13 according to different configurations. The first wire hole 14 and the second wire hole 15 are used in conjunction with the support frame 3.

[0030] It is worth mentioning that the support frame 3 is arranged at the first wire hole 14 and the second wire hole 15, and a fixing plate 33 is provided on the end surface of the support frame 3, and abuts against the bottom of the first concave cavity 12 and the second concave cavity 13. The fixing plate 33 is evenly distributed with a plurality of fastening screws 6 with the dot as the axis, so that the fixing plate 33 is connected and fixed with the first concave cavity 12 and the second concave cavity 13. The fixing plate 33 is connected and fixed with the threading holes 41 of the first concave cavity 12 and the second concave cavity 13 by the fastening screws 6, or is easy to disassemble and replace;

[0031] It is worth mentioning that the outer wall of the support frame 3 is provided with an external thread groove 34, the outer wall of the support frame 3 is provided with a support ring 35, baffles 36 are provided at both ends of the support frame 3, and abut against the threading column 4, the outer wall of the support frame 3 is evenly distributed with a plurality of first limit blocks 37 and second limit blocks 38 with the dot as the axis, the external thread groove 34 is used in conjunction with the internal thread groove 52, the support ring 35 provides a support point for the spring gasket 7, the baffle 36 prevents the wire from passing through the threading column 4, and the threading column 4 will move with the wire, the first limit block 37 limits the distance of the clamping part 51 retreating to the through hole 31, and the second limit block 38 limits the distance of the clamping part 51 moving in the guide part 32;

[0032] It is worth mentioning that the fastening nut 5 is provided with an internal thread groove 52, which is engaged with the external thread groove 34. The fastening nut 5 is provided with a fixing block 53 corresponding to the through hole 31, and is connected and fixed with one end of the clamping part 51. A pressure ring 54 is provided at the bottom of the fixing block 53, and a stop block 55 is provided on the pressure ring 54. The stop block 55 and the fixing block 53 are arranged between the first limit block 37 and the second limit block 38. The internal thread groove 52 is engaged with the external thread groove 34 so that the fastening nut 5 is fixed in the moved position after rotation. The fixing block 53 is used in conjunction with the first limit block 37, the stop block 55 is used in conjunction with the second limit block 38, and the pressure ring 54 is used in conjunction with the flat gasket 8. One end of the clamping part 51 is only connected to the fixing block 53, so that the clamping part 51 is convenient for the inward movement of the track of the guide part 32.

[0033] It is worth mentioning that the support ring 35 is provided with a spring washer 7, and the end surface of the spring washer 7 is provided with a flat washer 8, which abuts against the pressure ring 54. The flat washer 8 increases the contact area with the spring washer 7. The spring washer 7 applies elastic force to the flat washer 8, so that the internal thread groove 52 is pressed against the external thread groove 34, thereby increasing the friction between the two, and further preventing the connection stability of the fastening nut 5 and the support frame 3;

[0034] It is worth mentioning that the shapes of the guide portion 32 and the clamping portion 51 are set to be arc-shaped, and the end surface of the clamping portion 51 inserted into the through hole 31 is provided with a chamfer 56, and the width of the clamping portion 51 is smaller than the width of the through hole 31. As the guide portion 32 gradually moves away from the entrance of the through hole 31, the depth of the guide portion 32 becomes shallower and shallower until it is flush with the inner wall of the support frame 3. The arc shape of the clamping portion 51 fits the guide portion 32 more closely, so that when the clamping portion 51 moves on the guide portion 32, as the depth gradually becomes shallower, the clamping portion 51 shrinks toward the center direction of the threading column 4, thereby achieving the clamping effect. The chamfer 56 not only facilitates the initial entry of the guide portion 32 into the through hole 31, but also reduces the distance between the guide portion 32 entering the threading column 4 and the support frame 3. When the fastening nut 5 rotates, it will move up or down for a distance. Therefore, by making the width of the clamping portion 51 smaller than the width of the through hole 31, space is provided for the fastening nut 5 to move up and down.

[0035] It is worth mentioning that the threading column 4 is provided with a plurality of threading holes 41, and sealing rings 9 are provided between the threading holes 41, the support frame 3 and the threading holes 41. The material of the threading column 4 is set to rubber, and the threading holes 41 are convenient for the entry of wires. The sealing ring 9 makes the connection between the support frame 3 and the first wire hole 14 and the second wire hole 15 tighter. The sealing ring 9 is arranged in the threading hole 41 to ensure that after the threading hole 41 is deformed, the sealing ring 9 fills the gap after the deformation, thereby further improving the sealing between the wire and the blocking device 2. Rubber has softness and deformability.

[0036] The use principle of the utility model is now described as follows:

[0037] After the wires have passed through all the threading holes 41, a wrench is used to abut against the fastening nut 5 and a rotational force is applied to make the fastening nut 5 rotate and the clamping portion 51 is guided by the guide portion 32 and inserted between the threading column 4 and the support frame 3, and then squeezed toward the center direction of the threading column 4, so that the threading hole 41 is deformed by the squeezing force, so that the threading hole 41 and the wire are more tightly connected, until the stop block 55 abuts against the second limit block 38, and the fastening nut 5 is unable to rotate due to excessive resistance, and the wire blocking step is completed;

[0038] When removing the wire, it is only necessary to apply opposite force to the fastening nut 5 until the fixing block 53 abuts against the first limit block 37 and the clamping portion 51 no longer applies contraction and clamping force to the threading column 4. At this time, the wire can be freely removed from the threading hole 41.

[0039] The above design scheme can make the product have the advantages of high sealing, convenient operation and stable connection.

[0040] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
