Description

A new type of electrical engineering cable protection device Technical Field

[0001] This invention relates to the field of electrical engineering technology, specifically to a novel electrical engineering cable protection device. Background Technology

[0002] Electrical engineering is a core and key discipline in modern science and technology. For example, the tremendous advancements in electronic technology have driven the arrival of the information age based on computer networks and will change human lifestyles and work patterns. Traditionally, electrical engineering was defined as the sum of disciplines related to the creation of electrical and electronic systems. This definition was already quite broad, but with the rapid development of science and technology, the concept of electrical engineering in the 21st century has far exceeded the scope of the above definition. A Stanford University professor pointed out that today's electrical engineering encompasses almost all engineering activities related to electronics and photonics. However, cables are used for data transmission, and protective devices are needed at cable connections, especially during cable use.

[0003] When applying for this invention, the applicant searched and found a Chinese patent that discloses a "novel electrical engineering cable protection device" with application number "202210155011.1". This patent mainly uses a fixing component to fix the cable and prevent the cable connection from shaking and falling off. A buffer component can buffer the cable when it is impacted, preventing the cable from breaking or being damaged. A lifting component can easily adjust the height. A lower placement slot and an upper placement slot can easily restrict the cable. However, this device requires a drive motor to fix the cable, which is inconvenient to use and cannot automatically tighten and fix the cable.

[0019] (III) Beneficial Effects

[0020] This invention provides a novel cable protection device for electrical engineering. It has the following beneficial effects:

[0021] 1. An adjustment mechanism is provided. When the cable passes through the placement slot of the lower clamp, the lower clamp moves downward under the action of gravity, causing the first rack to move downward. This, in turn, drives the third gear to rotate clockwise, which in turn drives the fourth gear to rotate three times the distance. This drives the gear plate to move upward, and with the connection of the fifth gear, it drives the second rack and the upper clamp to move downward three times the distance. This can clamp and fix the cable, preventing it from falling off.

[0022] 2. It is equipped with a sliding rod, sliding sleeve, spring, connecting rod and connecting plate to buffer the cable and prevent the cable from breaking or being damaged when it is subjected to impact.

[0023] 3. It is equipped with a lifting mechanism, which drives the first gear to rotate through the driving action of the drive motor, thereby driving the two second gears to rotate synchronously, realizing the synchronous rotation of the two threaded rods, so that the overall height can be adjusted.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example:

[0035] As shown in Figures 1-5, this embodiment of the invention provides a novel electrical engineering cable protection device, including a housing 1, a lifting mechanism 2, a movable frame 3, and an adjustment mechanism 10. The inner bottom of the housing 1 is adjusted by the lifting mechanism 2 to drive the movable frame 3 to rise and fall. Specifically, the lifting mechanism 2 includes a drive motor 21 fixedly connected to the middle of the inner bottom of the housing 1. A first gear 22 is fixedly connected to the output end of the drive motor 21. Second gears 23 are meshed on both sides of the first gear 22. Threaded rods 24 are fixedly connected to the middle of the two second gears 23. The movable frame 3 is threadedly connected to the two threaded rods 24.

[0036] The above structure, through the driving action of the drive motor 21, drives the first gear 22 to rotate, which in turn drives the two second gears 23 to rotate synchronously, thereby realizing the synchronous rotation of the two threaded rods 24, which allows for overall height adjustment.

[0037] A sliding rod 4 is fixedly connected to the inner bottom of the movable frame 3. Sliding sleeves 5 are slidably sleeved on the outer surfaces of both ends of the sliding rod 4. Springs 6 are also fixedly sleeved on both ends of the sliding rod 4. The two ends of the springs 6 are fixedly connected to the movable frame 3 and the sliding sleeves 5 respectively. A connecting rod 7 is rotatably connected to the upper surface of the sliding sleeves 5. A connecting plate 8 is rotatably connected to the upper end of the connecting rod 7. Slider blocks 15 are fixedly connected to both sides of the connecting plate 8. Sliding grooves 16 are opened on both sides of the inner wall of the movable frame 3. The sliders 15 are slidably connected to the sliding grooves 16, which serves to limit the sliding.

[0038] The above structure can buffer the cable, cushioning it when it is subjected to impact, thus preventing the cable from breaking or being damaged.

[0039] A base plate 9 is fixedly connected to the upper surface of the connecting plate 8. An upper clamping plate 11 and a lower clamping plate 12 are provided on the upper side of the base plate 9. Several placement slots 13 are opened on the opposite surfaces of the upper clamping plate 11 and the lower clamping plate 12. The upper clamping plate 11 and the lower clamping plate 12 move towards each other to clamp the cable. An elastic telescopic rod 14 is fixedly connected to the middle of the upper surface of the base plate 9. The lower clamping plate 12 is fixedly connected to the upper end of the elastic telescopic rod 14. Two first limiting plates 91 are fixedly connected to the left side of the upper surface of the base plate 9, and two second limiting plates 92 are fixedly connected to the right side of the upper surface of the base plate 9. An adjustment mechanism 10 is set on the first limiting plate 91. The upper clamping plate 11 and the lower clamping plate 12 are slidably connected to the second limiting plate 92. When the lower clamping plate 12 is pressed down, the upper clamping plate 11 is driven to follow and move three times the distance by the adjustment mechanism 10.

[0040] Specifically, the adjusting mechanism 10 includes a first rack 101 fixedly connected to the left side of the lower clamping plate 12, a third gear 102 meshing with the left side of the first rack 101, a fourth gear 103 fixedly connected to the rear side of the third gear 102 via a rotating shaft, the number of teeth of the fourth gear 103 being three times the number of teeth of the third gear 102, a toothed plate 104 meshing with the left side of the fourth gear 103, a fifth gear 105 meshing with the upper right side of the toothed plate 104, a second rack 106 meshing with the right side of the fifth gear 105, and the second rack 106 fixedly connected to the upper clamping plate 11.

[0041] In the above structure, when the cable passes through the placement slot 13 of the lower clamping plate 12, the lower clamping plate 12 moves downward under the action of gravity, causing the first rack 101 to move downward, which in turn drives the third gear 102 to rotate clockwise, which in turn drives the fourth gear 103 to rotate three times the distance, which in turn drives the toothed plate 104 to move upward, and under the connection of the fifth gear 105, drives the second rack 106 and the upper clamping plate 11 to move downward three times the distance, thus pressing and fixing the cable to prevent it from falling off.

[0042] Secondly, a lid 17 is hinged to the upper surface of the housing 1 for sealing and protection when not in use.

[0043] Working principle: When using this new type of electrical engineering cable protection device, open the box cover 17, turn on the power of the drive motor 21, and adjust the overall height so that the upper clamping plate 11 and the lower clamping plate 12 are exposed.

[0044] The cable is passed through the placement slot 13 of the lower clamping plate 12. At the same time, under the action of gravity, the lower clamping plate 12 is moved downward, causing the first rack 101 to move downward, which in turn drives the third gear 102 to rotate clockwise, and drives the fourth gear 103 to rotate three times the distance, which in turn drives the toothed plate 104 to move upward. Under the connection of the fifth gear 105, the second rack 106 and the upper clamping plate 11 are driven to move downward three times the distance, which can press and fix the cable to prevent it from falling off.

[0045] Secondly, the spring 6 can buffer the cable when it is subjected to impact, thus preventing the cable from breaking or being damaged.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
