SPECIFIC EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present utility model: an internal cable installation structure of an electrical automation device, including a mounting plate 1 installed inside the electrical automation device to provide support. There are two groups of mounting plates 1. A support plate 2 for supporting multiple positioning frames 3 is fixedly installed between the two groups of mounting plates 1. A positioning frame 3 for supporting and clamping the cable is provided at the top of the support plate 2. A clamping assembly is provided at the top of the positioning frame 3. The clamping assembly includes a bidirectional threaded rod 33 that drives two clamping plates 31 and rubber pads 32 to move simultaneously to clamp and fix the cable. The bidirectional threaded rod 33 penetrates and is rotatably connected to the right side of the positioning frame 3. The inner wall of the top of the positioning frame 3 is slidably connected with a clamping plate 31 that drives the rubber pad 32 to move to clamp cables of different thicknesses and install them inside the electrical automation device.

[0034] Referring to Figure 2 , Figure 3 and Figure 4 , a disassembly and assembly component is provided between the support plate 2 and the positioning frame 3. The disassembly and assembly component includes a positioning groove 49 and a positioning block 48. After the positioning block 48 slides into the positioning groove 49 and cooperates with the limiting block 46 to slide into the limiting groove 410, the positioning frame 3 can be quickly installed, improving the installation convenience. The positioning block 48 is inserted into the inner wall of the positioning groove 49. A limiting groove 410 for cooperating with the limiting block 46 to slide into the limiting groove 410 to install and limit the positioning frame 3 is provided through the middle of the positioning block 48. A chute one 43 for providing space for the convex block 42 to move is provided on the front surface of the support plate 2. A chute two 44 for providing space for the guide block 4 to move is provided above the chute one 43 on the front surface of the support plate 2. A guide block 4 that drives the limiting block 46 to move is slidably connected to the inner wall of the chute two 44. A limiting block 46 that can slide into the limiting groove 410 to limit the positioning block 48 and the positioning frame 3 is fixedly connected to the left side of the guide block 4.

[0035] Referring to Figure 1 , Figure 4 and Figure 5, there are two sets of clamping plates 31, and the two sets of clamping plates 31 are symmetrically arranged with the center line of the positioning frame 3 as the axis of symmetry. The two sets of clamping plates 31 support two sets of rubber pads 32. Both sets of clamping plates 31 are threadedly connected to the outer wall of the bidirectional threaded rod 33. By rotating the bidirectional threaded rod 33 which is threadedly connected to the two sets of clamping plates 31, the two sets of clamping plates 31 move simultaneously in opposite directions, so that the two sets of clamping plates 31 move inward simultaneously, driving the two sets of rubber pads 32 to move inward simultaneously, thereby clamping and fixing the cable. Since the rubber pad 32 is made of rubber material, due to the elasticity and friction of the rubber pad 32 itself, the fixing effect on the cable can be further enhanced, and the stability of the installation is increased.

[0036] Furthermore, a rubber pad 32 is fixedly connected to the right side of the clamping plate 31. Since the rubber pad 32 is made of rubber material, due to the elasticity and friction of the rubber pad 32 itself, the fixing effect on the cable can be further enhanced, and the stability of the installation is increased. The rubber pad 32 is set in a semi-circular arc shape. By setting it in a semi-circular arc shape and rubber material, the friction with the cable can be increased, and at the same time, the fitting degree with the cable can be increased, which can further enhance the fixing effect on the cable and increase the stability of the installation.

[0037] Refer to Figure 2 , Figure 3 and Figure 4 , the top end of the limit block 46 is set as an inclined surface. The limit block 46 slides on the inner wall of the positioning groove 49. By setting the top end of the limit block 46 as an inclined surface, when installing the positioning frame 3, after directly moving the positioning frame 3 to drive the positioning block 48 to slide into the positioning groove 49, when the positioning block 48 contacts the top inclined surface of the limit block 46, the inclined surface is squeezed so that the limit block 46 moves to the right, driving the guide block 4 to move and squeeze the spring 47. When the positioning block 48 slides to the bottom end of the positioning groove 49 and at the same time the positioning frame 3 contacts the top end of the support plate 2, at this time the limit groove 410 is aligned with the limit block 46. At this time, due to the reverse acting force of the spring 47 being squeezed, the limit block 46 resets and slides into the limit groove 410, so that the positioning frame 3 can be quickly installed, increasing the convenience of installing the positioning frame 3, and at the same time further improving the efficiency of cable installation.

[0038] Refer to Figure 2 , Figure 3 and Figure 4, on the right side of the guiding block 4, there is a spring 47 fixedly connected. The movement of the limiting block 46 drives the guiding block 4 to move and compress the spring 47. Then, with the reverse force of the compressed spring 47, the limiting block 46 quickly resets and slides into the limiting groove 410 to quickly limit the positioning frame 3. The other end of the spring 47 is fixedly connected to the inner wall of the right support plate 2 near the second chute 44. Below the first chute 43 on the front surface of the support plate 2, there is a third chute 45 providing a moving space for the push plate 41. Slidingly connected to the inner wall of the third chute 45 is a push plate 41 that drives multiple groups of convex blocks 42 to move simultaneously, pushing multiple groups of guiding blocks 4 to move. Thus, the limit of multiple groups of positioning frames 3 can be released simultaneously, facilitating the quick removal of the positioning frames 3. Fixedly connected to the top of the push plate 41 are multiple groups of convex blocks 42 that push multiple groups of guiding blocks 4, enabling the quick release of the limit of multiple groups of positioning frames 3. The convex blocks 42 are slidingly connected to the inner wall of the first chute 43 on the left side near the guiding block 4. There are multiple groups of positioning frames 3, guiding blocks 4, and convex blocks 42, and multiple groups of positioning frames 3, guiding blocks 4, and convex blocks 42 are evenly arranged on the support plate 2. By setting multiple groups, multiple groups of cables can be installed simultaneously, and multiple groups of cables can be clamped and installed.

[0039] Working principle: When in use, first, after being installed inside the electrical automation equipment through two mounting plates 1, the support plate 2 can provide stable support. When it is necessary to fix the cable, at this time, the positioning frame 3 is installed. Directly moving the positioning frame 3 drives the positioning block 48 to slide into the positioning groove 49. When the positioning block 48 touches the top inclined surface of the limiting block 46, it will squeeze the inclined surface, causing the limiting block 46 to move to the right, driving the guiding block 4 to move and compress the spring 47. When the positioning block 48 slides to the bottom of the positioning groove 49 and at the same time the positioning frame 3 touches the top of the support plate 2, at this time, the limiting groove 410 is aligned with the limiting block 46. Through the reverse force of the compressed spring 47, the limiting block 46 resets and slides into the limiting groove 410, thus quickly completing the installation of the positioning frame 3, increasing the convenience of the installation of the positioning frame 3, and at the same time further improving the efficiency of cable installation.

[0040] After the positioning frame 3 is installed, different thicknesses of cables or multiple groups of cables are passed through the two sets of clamping plates 31 and rubber pads 32 at the top of the positioning frame 3. Subsequently, by rotating the bidirectional threaded rod 33, since the two sets of clamping plates 31 are both threadedly connected to the outer wall of the bidirectional threaded rod 33, rotating the bidirectional threaded rod 33 will drive the two sets of clamping plates 31 to move in opposite directions simultaneously. When the two sets of clamping plates 31 move inward simultaneously, they will drive the rubber pads 32 to move inward simultaneously. Due to the elasticity and friction of the rubber pads 32, the cables can be tightly clamped and fixed. At the same time, the bidirectional threaded rod 33 can cooperate with the two sets of clamping plates 31 and rubber pads 32 to simultaneously fix different thicknesses of cables or multiple groups of cables. At the same time, the rubber pads 32 are set in a semi-circular arc shape and made of rubber material, which increases the friction and fit with the cables, further enhances the fixing effect of the cables, improves the installation stability, and the clamping component can adapt to various cables with different thicknesses and quantities, or the situation where multiple groups of cables with different thicknesses exist simultaneously, and can be easily clamped and installed. The movement of the bidirectional threaded rod 33 in cooperation with the rubber pads 32 is stable and uniform, ensuring the uniform distribution of the clamping force, thereby reducing the damage caused by excessive local pressure on the cables during the fixing process, increasing the service life of the cables, and improving the installation effect of the internal cables of the electrical automation equipment.

[0041] By moving the guiding block 4 to drive the limiting block 46 out of the limiting groove 410, the positioning of the positioning frame 3 can be quickly released, so that the installation of the positioning frame 3 can be increased or decreased according to the number of cables. At the same time, by moving the push plate 41 to slide in the third chute 45, a plurality of convex blocks 42 can be driven to move and push a plurality of guiding blocks 4. At this time, a plurality of limiting blocks 46 can be cooperated to slide out of the limiting groove 410, and a plurality of positioning frames 3 can be simultaneously released from the limit for removal, improving the convenience of removal and further improving the disassembly and assembly efficiency.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
