Description

Technical Field

[0001] The present invention relates to the technical field of power cords, in particular to a power cord with anti-drop protection. Background Art

[0002] The power cord is a wire used to transmit electric current and is widely used in electrical appliances, power tools, and instruments. The power cord is the most basic part of a device. Without the power cord, most devices will not work.

[0003] For example, a power cord with publication number CN203351895U. A power cord includes a plug and a power cord body connected to the plug, wherein the power cord body is arranged in a continuous bending section, and a connecting layer is provided between two adjacent bending sections to connect the two and facilitate separation of the two. As can be seen from the above technical solution, the utility model arranges the power cord body into connected bending sections, and each bending section is connected by a connecting layer. The user can tear off the corresponding bending section according to the actual length of the power cord required, thereby avoiding the inconvenience caused by the power cord being too long;

[0004] Another example is a power cord with publication number CN101593883A, which is characterized by including a power cord with a bifurcated dual-plug power cord, a bifurcated device connected to one power cord, and two different power plugs on each bifurcated device, including a left bifurcated device on the power cord for branching a power branch line to the left and connecting a power plug to the power branch line. The technical solution provided by the present invention has the advantage that the power cord is provided with two plugs, so that power can be received from both plugs separately, making it convenient for users to use;

[0005] When in use, the device in the above application only has the most basic plug-in connection function and does not have a secondary stable structure. When the wiring is accidentally touched by the outside world, it may fall off, which will affect the normal use of the appliance and bring unnecessary trouble to the user.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original power cord. Summary of the Invention

[0007] The object of the present invention is to provide a power cord with anti-drop protection to solve the problem raised in the above-mentioned background art that, when in use, the power cord only has the most basic plug-in connection function and does not have a secondary stable structure. When the wiring is accidentally touched by the outside world, it may fall off, which will affect the normal use of the appliance and cause unnecessary trouble to the user.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a power cord with anti-drop protection, comprising a connector and an upper support rod, wherein a connecting plate is fixedly mounted on the right side of the connector, a wire body is fixedly connected to the right side of the connecting plate, a plug is fixedly connected to the end of the wire body, and a contact piece is fixedly connected to the surface of the plug;

[0009] The upper support rod is slidably connected to the inside of the joint, and a mounting hole is opened on the surface of the joint;

[0010] A power cord with anti-drop protection, further comprising:

[0011] A lower support rod, the lower support rod being slidably connected to the interior of the joint, and a protrusion being fixedly mounted on a side surface of the lower support rod;

[0012] a clamping block, the clamping block being slidably connected to the interior of the joint;

[0013] A connecting rod, wherein the right side of the connecting rod is slidably connected to the interior of the connecting plate, and the left side of the connecting rod is slidably connected to the interior of the joint.

[0014] Preferably, the surface of the upper support rod is an inclined structure, and a slider is fixedly installed on the side of the upper support rod. A slide groove corresponding to the slider is opened inside the joint. When in use, the joint is inserted into the interface of the external electrical appliance. At this time, the inclined surface of the upper support rod will be squeezed, and the upper support rod will move toward the inside of the joint. When the upper support rod moves, it drives the slider to slide inside the slide groove. The slider and the slide groove limit the moving distance of the upper support rod, thereby improving stability.

[0015] Preferably, a first spring that plays an elastic reset role is fixedly installed on the lower surface of the upper support rod, and the other side of the first spring is fixedly connected to the inner wall of the joint. When the upper support rod descends, it will squeeze the first spring. At this time, under the action of the first spring, the upper support rod has a tendency to move toward the outside of the joint. At this time, the upper support rod increases the friction between the joint and the external electrical interface, thereby increasing stability and achieving the purpose of preventing falling off.

[0016] Preferably, a fixed block is fixedly installed on the other side of the upper support rod, and a column is fixedly installed on the lower surface of the fixed block, and the column corresponds to the block one by one. When the upper support rod descends, the column will be driven to descend synchronously through the fixed block.

[0017] Preferably, a slot corresponding to the block is provided on the side of the lower support rod, and a groove corresponding to the protrusion is provided inside the joint. Initially, the lower support rod stays stably in the joint through the block and the slot (at this time, the end of the lower support rod is located inside the joint), and when the upper support rod descends, the column will be driven to descend synchronously through the fixed block, and finally the column will enter the deep groove and push the block to move away from the slot through the deep groove.

[0018] Preferably, a second spring that plays an elastic reset role is fixedly installed on the upper surface of the lower support rod, and the other side of the second spring is fixedly connected to the inner wall of the joint, and the second spring is initially in a compressed state. After the end of the blocking block is driven out of the slot by the column, the lower support rod moves out of the joint under the elastic force of the second spring and supports the interface of the external electrical appliance, cooperating with the upper support rod, thereby increasing the friction between the joint and the interface of the external electrical appliance, thereby increasing stability and optimizing the purpose of preventing falling off.

[0019] Preferably, the upper surface of the block is provided with a deep groove corresponding to the column, and the lower surface of the end of the block is inclined. The deep groove facilitates the operation of the column, and when the lower support rod moves, the protrusion and the groove limit the moving distance of the lower support rod, thereby improving stability.

[0020] Preferably, a third spring having an elastic reset function is fixedly mounted on the side of the block, and the other side of the third spring is fixedly connected to the inner wall of the joint, so that the third spring facilitates the movement and reset of the block.

[0021] Preferably, the side section of the connecting rod is viewed as an inverted "L" structure, and the end of the connecting rod is located on the outside of the connecting plate, and a button is fixedly installed at the end of the connecting rod, and the connecting rod and the upper support rod are fixedly connected. When the connector needs to be unplugged, press the button first, and the button drives the upper support rod to move toward the inside of the connector through the connecting rod. At this time, the friction between the connector and the external electrical interface is reduced, which facilitates the staff to pull out the connector.

[0022] Preferably, the upper support rod passes through the interior of the joint, and the upper support rods are evenly spaced inside the joint, and the upper support rods correspond to the lower support rods one by one. After the joint is unplugged from the external electrical socket, the lower support rod is pressed into the interior of the joint (the lower support rod will squeeze the second spring). At this time, the inclined surface of the card block will be squeezed by the surface of the lower support rod, and the card block will move in the direction of squeezing the third spring. When the protrusion moves to the other side of the groove, the card block and the card slot are in the same horizontal direction. At this time, the card block enters the interior of the card slot under the action of the third spring, that is, the lower support rod returns to its original position, which is convenient for the next use.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the power cord with anti-drop protection adopts a new structural design, the specific contents of which are as follows:

[0024] (1) When the power cord with anti-drop protection is used, the connector is inserted into the interface of an external electrical appliance. At this time, the inclined surface of the upper support rod will be squeezed, and the upper support rod moves in the direction of squeezing the first spring. Therefore, when working, the upper support rod has a tendency to move toward the outside of the connector under the action of the first spring. At this time, the upper support rod increases the friction between the connector and the interface of the external electrical appliance, thereby increasing stability and achieving the purpose of preventing drop-off;

[0025] (2) The power cord with anti-drop protection has the following features: initially, the end of the card block is located inside the card slot, and the lower support rod stays stably inside the connector. When the upper support rod descends, the column is driven to descend synchronously through the fixed block. When the column descends, the card block is driven out of the card slot through the deep groove. At this time, the lower support rod is moved out of the connector and supports the interface of the external electrical appliance under the action of the second spring, cooperating with the upper support rod to increase the friction between the connector and the interface of the external electrical appliance, thereby increasing stability and optimizing the purpose of preventing drop-off;

[0026] (3) When the power cord with anti-drop protection needs to be unplugged from the external electrical interface, the user first presses the button. The button drives the upper support rod to move toward the inside of the connector through the connecting rod. At this time, the friction between the connector and the external electrical interface is reduced, which facilitates the staff to unplug the connector. After unplugging the connector from the external electrical socket, the user presses the lower support rod toward the inside of the connector (the lower support rod will squeeze the second spring). At this time, the inclined surface of the card block will be squeezed by the surface of the lower support rod, and the card block will move in the direction of squeezing the third spring. When the protrusion moves to the other side of the groove, the card block and the card slot are in the same horizontal direction. At this time, the card block enters the inside of the card slot under the action of the third spring, that is, the lower support rod returns to its original position, which is convenient for the next use.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-8 The present invention provides a technical solution: a power cord with anti-drop protection, comprising a connector 1 and an upper support rod 5, a connecting plate 2 fixedly mounted on the right side of the connector 1, a wire body 3 fixedly connected to the right side of the connecting plate 2, a plug 4 fixedly connected to the end of the wire body 3, and a contact piece 22 fixedly connected to the surface of the plug 4, the upper support rod 5 slidably connected to the inside of the connector 1, and a mounting hole 11 opened on the surface of the connector 1;

[0038] A power cord with anti-drop protection, further comprising:

[0039] The lower support rod 12 is slidably connected to the inside of the joint 1, and the side of the lower support rod 12 is fixedly installed with a protrusion 14, a block 16, and the block 16 is slidably connected to the inside of the joint 1, and the connecting rod 20, the right side of the connecting rod 20 is slidably connected to the inside of the connecting plate 2, and the left side of the connecting rod 20 is slidably connected to the inside of the joint 1.

[0040] The surface of the upper support rod 5 is an inclined structure, and a slider 6 is fixedly installed on the side of the upper support rod 5. A sliding groove 7 corresponding to the slider 6 is opened inside the joint 1. The lower surface of the upper support rod 5 is fixedly installed with a first spring 10 that plays an elastic reset role, and the other side of the first spring 10 is fixedly connected to the inner wall of the joint 1.

[0041] When in use, the connector 1 is inserted into the interface of the external electrical appliance. At this time, the inclined surface of the upper support rod 5 will be squeezed, and the upper support rod 5 will move toward the inside of the connector 1. When the upper support rod 5 moves, it drives the slider 6 to slide inside the slide groove 7. The slider 6 and the slide groove 7 limit the moving distance of the upper support rod 5, thereby improving stability. When the upper support rod 5 descends, it will squeeze the first spring 10. At this time, under the action of the first spring 10, the upper support rod 5 has a tendency to move toward the outside of the connector 1. At this time, the upper support rod 5 increases the friction between the connector 1 and the external electrical appliance interface, thereby increasing stability and achieving the purpose of preventing falling off.

[0042] A fixed block 8 is fixedly installed on the other side of the upper support rod 5, and a column 9 is fixedly installed on the lower surface of the fixed block 8, and the column 9 corresponds one-to-one with the block 16. A card slot 19 corresponding to the block 16 is opened on the side of the lower support rod 12, and a groove 15 corresponding one-to-one with the protrusion 14 is opened inside the joint 1.

[0043] A second spring 13 that plays an elastic reset role is fixedly installed on the upper surface of the lower support rod 12, and the other side of the second spring 13 is fixedly connected to the inner wall of the joint 1, and the second spring 13 is initially in a compressed state. A deep groove 18 corresponding to the column 9 is opened on the upper surface of the block 16, and the lower surface of the end of the block 16 is inclined. A third spring 17 that plays an elastic reset role is fixedly installed on the side of the block 16, and the other side of the third spring 17 is fixedly connected to the inner wall of the joint 1.

[0044] When the upper support rod 5 moves, it will drive the protrusion 14 to slide inside the groove 15. The protrusion 14 and the groove 15 limit the moving distance of the lower support rod 12, thereby ensuring stability.

[0045] The upper support rod 5 passes through the interior of the joint 1, and the upper support rods 5 are evenly spaced inside the joint 1, and the upper support rods 5 correspond one-to-one with the lower support rods 12. The side section of the connecting rod 20 is viewed as an inverted "L" structure, and the end of the connecting rod 20 is located on the outside of the connecting plate 2, and a button 21 is fixedly installed at the end of the connecting rod 20, and the connecting rod 20 and the upper support rod 5 are fixedly connected.

[0046] When it is necessary to unplug the connector 1 from the external electrical interface, first press the button 21. The button 21 drives the upper support rod 5 to move toward the inside of the connector 1 through the connecting rod 20 of the inverted "L" structure. At this time, the friction between the connector 1 and the external electrical interface is reduced, which facilitates the staff to unplug the connector 1. After unplugging the connector 1 from the external electrical socket, press the lower support rod 12 into the inside of the connector 1 (the lower support rod 12 will squeeze the second spring 13). At this time, the inclined surface of the block 16 will be squeezed by the surface of the lower support rod 12, and the block 16 will move in the direction of squeezing the third spring 17. When the protrusion 14 moves to the other side of the groove 15, the block 16 and the groove 19 are in the same horizontal direction. At this time, the block 16 enters the inside of the groove 19 under the action of the third spring 17, that is, the lower support rod 12 returns to its original position, which is convenient for the next use.

[0047] Working principle: When using the power cord with anti-drop protection, first place the device at the location where the work needs to be done. Figures 1-8 When in use, the connector 1 is inserted into the interface of the external electrical appliance. At this time, the inclined surface of the upper support rod 5 will be squeezed, and the upper support rod 5 will move in the direction of squeezing the first spring 10. At this time, the upper support rod 5 has a tendency to move toward the outside of the connector 1 under the action of the first spring 10. At this time, the upper support rod 5 increases the friction between the connector 1 and the interface of the external electrical appliance, thereby increasing stability and achieving the purpose of preventing it from falling off;

[0048] Initially, the lower support rod 12 stays stably in the joint 1 through the block 16 and the slot 19 (the end of the lower support rod 12 is located inside the joint 1 at this time), and when the upper support rod 5 descends, it drives the column 9 to descend through the fixing block 8. When the column 9 descends, it pushes the block 16 out of the slot 19 through the deep groove 18. At this time, the lower support rod 12 moves out of the joint 1 under the elastic force of the second spring 13 and supports the interface of the external electrical appliance, cooperating with the upper support rod 5, increasing the friction between the joint 1 and the external electrical appliance interface, thereby increasing stability and optimizing the purpose of preventing falling off;

[0049] When it is necessary to unplug the connector 1 from the external electrical interface, first press the button 21. The button 21 drives the upper support rod 5 to move toward the inside of the connector 1 through the inverted "L" structure connecting rod 20. At this time, the friction between the connector 1 and the external electrical interface is reduced, making it easier for the staff to unplug the connector 1.
