Abstract
Description
Technical Field
[0001] This utility model belongs to the field of safe electricity use technology, specifically a safe electricity use device. Background Technology
[0002] Chinese Patent Publication No. CN216699283U describes a technical problem: "In existing air switches, the internal wiring is usually tightly wrapped by external components. Over time, this can lead to overheating and metal fatigue, causing wiring deformation. Furthermore, the wiring inside the air switch is often fixed; accidental pulling or loosening over time can cause the wiring to loosen, potentially leading to burnout." This patent addresses this problem by providing through-holes to dissipate heat from the wiring inside the casing, preventing metal fatigue and effectively dissipating heat to avoid deformation. It is highly practical. Additionally, the patent incorporates rollers, allowing for sufficient movement of the wiring while preventing damage and creases, ensuring the quality of the wiring. These measures solve the technical problems.
[0003] In this patent, when the circuit is accidentally pulled, although the circuit has a certain amount of room to stretch, if the room to stretch is insufficient or the pulling force is too great, the circuit inside the circuit switch will still become loose, causing the wiring to become loose, and in severe cases, the circuit switch will be burned out.
[0004] Therefore, a safe electrical device is needed to solve the problems mentioned above. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a safe electrical device that effectively solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe electrical device, comprising a housing, a baffle, and a protective sleeve. The baffle is fixedly connected to the outer side of the housing, and a protective sleeve is provided on the inner side of the baffle. A connecting pipe is movably inserted into the inner side of the baffle and through the inner wall of the protective sleeve. A through hole is provided on the inner wall of the protective sleeve for heat dissipation. A protective component is fitted onto the inner wall of the protective sleeve, and gas springs are fixedly connected to the outer side of the protective sleeve on both sides of the protective component.
[0007] Furthermore, the connecting pipe is made of stainless steel, and the connecting pipe is movably connected to the protective sleeve.
[0008] Furthermore, the protective assembly includes a sleeve, a connecting groove, a fixing block, and a connecting rod. The inner wall of the sleeve, located below the gas spring, has a groove. The connecting rod is slidably connected to the inner side of the groove. The sleeve is fixedly connected to the inner side of the connecting rod. The inner wall of the sleeve has a connecting groove. The bottom of the connecting groove is fixedly connected to a fixing block. The inner wall of the fixing block has a threaded hole.
[0009] Furthermore, a clamping assembly is fitted inside the sleeve. The clamping assembly includes a rubber pad and a rod. The rubber pad is fitted inside the sleeve. The inner wall of the sleeve is fixedly connected to the bottom of the rubber pad. The top of the rubber pad is in contact with the inner wall of the sleeve. The rod is located inside the connecting groove and can slide along the inner side of the connecting groove.
[0010] Furthermore, the inner wall of the insertion rod is threaded with a screw, and the inner wall of the insertion rod has an opening that matches the size of the fixing block. When the insertion rod moves along the inner side of the connecting groove to the bottom of the connecting groove, the fixing block is embedded in the opening. At this time, the screw is turned so that the screw is threadedly connected to the threaded hole, thereby fixing the insertion rod.
[0011] Furthermore, the telescopic end of the gas spring is fixedly connected to the connecting rod, which can move upward along the groove to compress the gas spring and cause it to contract. The inner wall of the protective sleeve is provided with a strip groove, through which the insertion rod passes and can move along the inner side of the strip groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of a gas spring, the telescopic end of the gas spring will retract, causing the sleeve to move up a certain distance, thereby offsetting part of the pulling force. At the same time, with the use of rubber gaskets, a large frictional force will be generated between the gas spring and the outer sheath of the circuit, which will offset the remaining pulling force. This prevents the circuit inside the circuit breaker from becoming loose when the circuit is not stretched enough or the pulling force is too large, thus preventing the circuit connection from becoming loose and causing the circuit breaker to burn out.
[0014] 2. This utility model, through the setting of through holes, allows for heat dissipation. In conjunction with the use of a connecting pipe, which runs through the protective sleeve, the connecting pipe can be connected to the external environment, allowing airflow to pass through the connecting pipe, thereby carrying away the heat inside the protective sleeve and making the heat dissipation effect even better.
[0015] 3. In this utility model, the protective sleeve is installed on the outside of the outer shell by inserting the connecting pipe through the connecting pipe. The protective sleeve can be installed and removed by quickly disassembling the connecting pipe, and the protective sleeve can be replaced, making it convenient to use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Implementation examples, by Figure 1-4 This utility model discloses a safe electrical device, including a housing 1, a baffle 2, and a protective sleeve 3. The baffle 2 is fixedly connected to the outer side of the housing 1, and the protective sleeve 3 is disposed on the inner side of the baffle 2. A connecting pipe 4 is movably inserted into the inner side of the baffle 2 and through the inner wall of the protective sleeve 3. The connecting pipe 4 is made of stainless steel and is movably connected to the protective sleeve 3. A through hole 5 is opened in the inner wall of the protective sleeve 3 for heat dissipation. A protective component 6 is sleeved on the inner wall of the protective sleeve 3. Component 6 includes a sleeve 61, a connecting groove 62, a fixing block 63, and a connecting rod 64. The inner wall of the protective sleeve 3 and below the gas spring 7 is provided with a groove. The connecting rod 64 is slidably connected to the inner side of the groove. The sleeve 61 is fixedly connected to the inner side of the connecting rod 64. The inner wall of the sleeve 61 is provided with a connecting groove 62. The bottom of the connecting groove 62 is fixedly connected with a fixing block 63. The inner wall of the fixing block 63 is provided with a threaded hole. The gas spring 7 is fixedly connected to the outer side of the protective sleeve 3 and on both sides of the protective component 6.
[0024] A clamping assembly 8 is fitted inside the sleeve 61. The clamping assembly 8 includes a rubber gasket 81 and a rod 82. The rubber gasket 81 is fitted inside the sleeve 61, and the bottom of the rubber gasket 81 is fixedly connected to the inner wall of the sleeve 61. The top of the rubber gasket 81 is in contact with the inner wall of the sleeve 61. The rod 82 is located inside the connecting groove 62 and can slide along the inner side of the connecting groove 62. A screw is threaded onto the inner wall of the rod 82, and a section with dimensions matching those of the fixing block 63 is opened on the inner wall of the rod 82. With the fitting opening, when the insertion rod 82 moves along the inner side of the connecting groove 62 to the bottom of the connecting groove 62, the fixing block 63 is embedded in the opening. At this moment, the screw is turned so that the screw is threadedly connected to the threaded hole, thereby fixing the insertion rod 82. The telescopic end of the gas spring 7 is fixedly connected to the connecting rod 64. The connecting rod 64 can move up along the groove, thereby squeezing the gas spring 7 and causing the gas spring 7 to contract. The inner wall of the protective sleeve 3 is provided with a strip groove 9. The insertion rod 82 passes through the strip groove 9 and can move along the inner side of the strip groove 9.
[0025] Working principle: When in use, the wire is passed through the protective sleeve 3, so that the wire passes through the clamping component 8 inside the protective sleeve 3. Then, the plug rod 82 is manually pushed down along the connecting groove 62. Since the bottom of the rubber pad 81 is fixedly connected to the inner wall of the sleeve 61, the bottom of the rubber pad 81 will not move at this time. The plug rod 82 will drive the top of the rubber pad 81 to move, so that the rubber pad 81 is squeezed and bent. When the plug rod 82 moves to the bottom of the connecting groove 62, the center of the rubber pad 81 will finally protrude inward, thereby squeezing and clamping the wire. At the same time, since the rubber pad 81 is made of rubber, it will generate a large friction force with the outer sheath of the wire. When the plug rod 82 moves along the inner side of the connecting groove 62 to the bottom of the connecting groove 62, the fixing block 63 is embedded in the opening of the inner wall of the plug rod 82. At this time, the screw is turned so that the screw is threadedly connected to the threaded hole, thereby fixing the plug rod 82.
[0026] When the line is subjected to a large pulling force, the sleeve 61 will move upward along the inner side of the sleeve 3. Since the connecting rod 64 is fixedly connected to the gas spring 7, the telescopic end of the gas spring 7 will contract under the action of the gas spring 7, causing the sleeve 61 to move upward a certain distance, thereby offsetting part of the pulling force. When the offset pulling force is insufficient, since the rubber pad 81 is made of rubber, it will generate a large friction force with the outer sheath of the line, which will offset the remaining pulling force. This will prevent the line from becoming loose inside the circuit breaker when the line is not stretched enough or the pulling force is too large, and prevent the line connection from becoming loose, which could cause the circuit breaker to burn out.
[0027] When the circuit inside the casing 3 is working, it can dissipate heat through the through hole 5. Since the connecting pipe 4 runs through the casing 3, it can be connected to the external environment, allowing airflow to pass through the connecting pipe 4, thereby carrying away the heat inside the casing 3 and making the heat dissipation effect better. At the same time, the casing 3 is installed on the outside of the outer shell 1 through the insertion of the connecting pipe 4. The casing 3 can be installed and removed by quickly disassembling the connecting pipe 4, and the casing 3 can be replaced for convenient use.
