Description

Technical Field

[0001] This utility model relates to the field of power cord technology, specifically a power cord quick-change structure. Background Technology

[0002] A power cord is a basic accessory used to transmit electrical energy. One end connects to a power socket, and the other end connects to electrical equipment. Through the internal metal wires, it stably transmits alternating current or direct current from the power supply end to the electrical equipment, providing the necessary power support for the normal operation of the equipment.

[0003] Currently, power cords are mainly divided into two types: one is fixedly connected to the electrical equipment, and the other is plugged into the electrical equipment. Although fixedly connected power cords are secure, they are not easy to replace when damaged. Plug-in power cords, such as round-headed power cords, are easy to replace, but the connection is not secure and can easily detach from the electrical equipment under external force, making it difficult to ensure the continuous and stable operation of the electrical equipment. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change power cord structure that effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A quick-change power cord structure includes a socket on the surface of a device housing and a plug mounted on an insulating sleeve. An arc-shaped protrusion is provided on the outer side of the socket, and a slot is formed on the side surface of the arc-shaped protrusion. An arc-shaped insert is mounted on the outer surface of the insulating sleeve, which can rotate horizontally into the slot when the plug is inserted into the socket. A locking mechanism is provided on the outer surface of the insulating sleeve to lock the angle of the insulating sleeve when the plug is inserted into the socket.

[0007] Therefore, by horizontally inserting the arc-shaped plug into the slot and locking the angle of the insulating sleeve with the locking mechanism, the insulating sleeve cannot rotate and the arc-shaped plug cannot be pulled out of the slot in case of accidental contact. This ensures the reliability of the plug-socket connection and prevents it from disengaging under external force, thus ensuring the continuous and stable operation of the electrical equipment. When the power cord needs to be replaced, simply release the locking mechanism from the angle of the insulating sleeve, then rotate the insulating sleeve to pull the arc-shaped plug out of the slot, and then the plug can be directly pulled out of the socket for quick replacement.

[0008] Furthermore, the locking mechanism includes a sliding sleeve slidably disposed on the outer surface of the insulating sleeve. A guide rod is connected to the end face of the sliding sleeve facing the arc-shaped plug, and a positioning pin is installed at the end of the guide rod. A through hole and a positioning hole are provided at the bottom of the arc-shaped plug, and the positioning pin can pass through the through hole and be inserted into the positioning hole.

[0009] Furthermore, the outer surface of the insulating sleeve is provided with a shoulder, and a spring is fitted on the outer surface of the insulating sleeve, with the two ends of the spring abutting against the sliding sleeve and the shoulder respectively.

[0010] Furthermore, the inside of the arc-shaped insert has a sliding hole, and the guide rod is slidably disposed in the sliding hole.

[0011] Furthermore, the surface of the device housing is provided with a recess, and the insertion hole is coaxially disposed within the recess.

[0012] Furthermore, there are four arc-shaped protrusions, which are distributed coaxially and at equal angles on the inner wall of the recess. The number and distribution of the arc-shaped inserts and locating pins are consistent with those of the arc-shaped protrusions.

[0013] Furthermore, the outer surface of the sleeve is provided with anti-slip stripes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] This invention inserts the arc-shaped plug horizontally into the slot and locks the angle of the insulating sleeve with a locking mechanism. This prevents the insulating sleeve from rotating and the arc-shaped plug from being pulled out of the slot in case of accidental contact, thus ensuring the reliability of the plug-socket connection and preventing it from disengaging under external force. This ensures the continuous and stable operation of the electrical equipment. When the power cord needs to be replaced, simply release the locking mechanism from the angle of the insulating sleeve, then rotate the insulating sleeve to pull the arc-shaped plug out of the slot, and then the plug can be directly pulled out of the socket for quick replacement.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a quick-change power cord structure, including a socket 101 on the surface of a device housing 1 and a plug 201 on an insulating sleeve 2. An arc-shaped protrusion 102 is provided on the outer side of the socket 101, and a slot 103 is formed on the side surface of the arc-shaped protrusion 102. An arc-shaped insert 202 is mounted on the outer surface of the insulating sleeve 2. When the plug 201 is inserted into the socket 101, the arc-shaped insert 202 can rotate horizontally into the slot 103. A locking mechanism 3 is provided on the outer surface of the insulating sleeve 2 to lock the angle of the insulating sleeve 2 when the plug 201 is inserted into the socket 101.

[0024] In use, the angles of the arc-shaped plug 202 and the arc-shaped protrusion 102 are offset so that the plug 201 is inserted into the socket 101. Then, the insulating sleeve 2 is rotated at a certain angle, which can drive the arc-shaped plug 202 to be horizontally inserted into the slot 103, thereby initially locking the plug 201 so that it cannot be pulled out directly. In addition, the locking mechanism 3 locks the angle of the insulating sleeve 2, so that the insulating sleeve 2 cannot be rotated and the arc-shaped plug 202 cannot be pulled out of the slot 103 in case of accidental contact. Therefore, the reliability of the plug 201 and the socket 101 connection can be guaranteed, and it can be prevented from being dislodged under the action of external force, thus ensuring the continuous and stable operation of the electrical equipment. When it is necessary to replace the power cord, simply release the locking mechanism 3 from locking the angle of the insulating sleeve 2, and then rotate the insulating sleeve 2 to drive the arc-shaped plug 202 out of the slot 103. Then the plug 201 can be directly pulled out of the socket 101 for quick replacement.

[0025] Preferably, the locking mechanism 3 includes a sliding sleeve 301 slidably disposed on the outer surface of the insulating sleeve 2. A guide rod 302 is connected to the end face of the sliding sleeve 301 facing the arc-shaped insert 202, and a positioning pin 303 is installed at the end of the guide rod 302. A through hole 304 is opened at the bottom of the arc-shaped insert 202, and a positioning hole 305 is opened at the bottom of the arc-shaped insert 202. The positioning pin 303 can pass through the through hole 304 and be inserted into the positioning hole 305.

[0026] Holding the sliding sleeve 301, insert the plug 201 into the socket 101. When the plug 201 is fully inserted, it is blocked, allowing the sliding sleeve 301 to slide on the surface of the insulating sleeve 2. This pushes the positioning pin 303 to move below the arc-shaped plug 202. Then, rotate the sliding sleeve 301 to rotate the insulating sleeve 2, so that the arc-shaped plug 202 is horizontally inserted into the slot 103. Then slide the sliding sleeve 301 outward, so that the positioning pin 303 can be driven through the through hole 304 and inserted into the positioning hole 305 through the guide rod 302. At this time, the positioning pin 303 can fix the guide rod 302 in the arc-shaped protrusion 102, so that the insulating sleeve 2 cannot rotate and the arc-shaped plug 202 cannot be pulled out of the slot 103 in case of accidental contact. Therefore, the reliability of the plug 201 and the socket 101 connection can be guaranteed.

[0027] Preferably, the outer surface of the insulating sleeve 2 is provided with a shoulder 4, and a spring 401 is sleeved on the outer surface of the insulating sleeve 2. The two ends of the spring 401 abut against the sliding sleeve 301 and the shoulder 4, respectively.

[0028] The elastic force of the spring 401 pushes the sliding sleeve 301 to slide away from the plug 201, thereby driving the positioning pin 303 to be firmly inserted into the positioning hole 305, avoiding separation during use and ensuring the reliability of the connection.

[0029] Preferably, the arc-shaped insert 202 has a sliding hole 2021 inside, and the guide rod 302 is slidably disposed in the sliding hole 2021.

[0030] It can limit the angle of the sliding sleeve 301, so that when it rotates, it can drive the insulating sleeve 2 to rotate at the same time. It also provides a positioning function for the positioning pin 303, ensuring that the positioning pin 303 is always in the position of the corresponding positioning hole 305, which facilitates quick locking.

[0031] Preferably, the surface of the device housing 1 is provided with a recess 1001, and the insertion hole 101 is coaxially disposed in the recess 1001.

[0032] By setting the arc-shaped protrusion 102 on the inner wall of the recess 1001, the surface of the device housing 1 can be avoided from being abrupt, the aesthetics can be improved, and the possibility of the arc-shaped protrusion 102 colliding with external objects can be reduced.

[0033] Preferably, there are four arc-shaped protrusions 102, and the four arc-shaped protrusions 102 are distributed coaxially and at equal angles on the inner wall of the recess 1001. The number and distribution of the arc-shaped inserts 202 and the positioning pins 303 are consistent with those of the arc-shaped protrusions 102.

[0034] By using a four-point positioning method, the force can be evenly distributed under external pulling force, effectively reducing the possibility of the arc-shaped protrusion 102 or the arc-shaped insert 202 breaking and improving tensile strength.

[0035] Preferably, the outer surface of the sliding sleeve 301 is provided with anti-slip stripes.

[0036] The anti-slip stripes increase the friction between the slip sleeve 301 and the hand, reducing the possibility of slipping.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
