Description

Technical Field

[0001] The utility model relates to the technical field of chargers, and particularly to a fastening device for a charger head. Background Technique

[0002] A charger head, also known as a charger or power adapter, is an accessory for electronic devices, mainly used to provide power for other devices. It usually consists of two parts: one part is inserted into the power socket, and the other part is connected to the device that needs to be charged. The working principle of the charger head is to convert alternating current (AC) into direct current (DC) so that the device can use it.

[0003] However, in the prior art, when a traditional charger head is in use, the charging cable may be disconnected from the charger head due to reasons such as the user accidentally tripping or pulling, and the device cannot continue to receive power supply. It is necessary to reconnect the charging cable to continue charging, which brings inconvenience to the user. If it is often pulled or inserted and removed, it will accelerate its wear degree, and may even cause poor contact or complete failure, which will further affect the normal use of the device and may require additional maintenance or replacement costs.

[0021] 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.

[0022] The present utility model provides the following technical solutions: As Figures 1-4As shown in the figure, in this embodiment, a fastening device for a charger head includes: a fastening mechanism 1. The fastening mechanism 1 includes a charger head body 11. An interface 12 is provided on one side of the charger head body 11. A power cord 13 is provided on the side of the charger head body 11 close to the interface 12. A power plug 14 is provided at one end of the power cord 13 close to the interface 12. Two positioning blocks 15 are provided on both sides of the power plug 14. The outside of the power plug 14 is inserted into the interface 12. Two positioning blocks 15 are fixedly connected to both sides of the power plug 14. Fixing holes 16 are provided on both sides of the power plug 14. Fixing blocks 17 are provided at both ends of the side of the charger head body 11 close to the interface 12. Two positioning grooves 18 are provided on the opposite sides of the two fixing blocks 17. The outside of the positioning block 15 is slidably connected to the inner wall of the positioning groove 18. Fixing blocks 17 are fixedly connected to both ends of the side of the charger head body 11 close to the interface 12. Installation grooves 19 are provided in the middle of the two fixing blocks 17. Springs 111 are provided in the two installation grooves 19. Moving columns 110 are provided in the inner circles of the two springs 111. Clamping blocks 112 are provided at one ends of the two moving columns 110 close to the installation grooves 19. One end of the moving column 110 is fixedly connected to one end of the clamping block 112. The outside of the clamping block 112 is clamped in the fixing hole 16. Pulling rods 113 are provided at the ends of the two moving columns 110 away from the clamping blocks 112. The other end of the moving column 110 passes through the inner circle of the spring 111 and extends to the outside of the fixing block 17 and is fixedly connected to the outside of the pulling rod 113. One end of the spring 111 is fixedly connected to the inner wall of the installation groove 19 away from the clamping block 112. The other end of the spring 111 is fixedly connected to the side of the clamping block 112 close to the moving column 110. A protection mechanism 2 is provided on the outside of the charger head body 11.

[0023] In this embodiment, when the staff needs to prevent the power cord 13 from being disconnected from the charger head body 11, the two pulling rods 113 can be pulled respectively. Then the two pulling rods 113 will drive the moving columns 110 and the clamping blocks 112 to move in the direction of the force applied respectively. Therefore, the clamping block 112 will slide into the installation groove 19 and squeeze the spring 111, avoiding obstacles when the power plug 14 is inserted into the interface 12. Therefore, the power plug 14 can be inserted into the interface 12 through the positioning block 15 and the positioning groove 18. The positioning block 15 and the positioning groove 18 can not only ensure the accurate and stable insertion of the power plug 14, but also ensure that the positions of the fixing hole 16 and the clamping block 112 can be kept consistent after the insertion is completed. Therefore, when the end of the power plug 14 is completely inserted into the interface 12, the staff can release the pulling rod 113. The spring 111 will lose the acting force and then release the elastic force to push the clamping block 112 to be clamped in the fixing hole 16. Therefore, the power plug 14 and the charger head body 11 will be limited and fixed, achieving the effect of preventing disconnection and ensuring the normal use of the charger head, avoiding the charging cable from being detached from the charger head due to external factors.

[0024] As Figure 1 and Figure 4 shown, the protection mechanism 2 includes a protective sleeve 21 which is nested outside the charger body 11. A plurality of heat dissipation grooves 22 are formed in the outer side of the protective sleeve 21. Rubber suction cups 23 are fixedly connected to four corners of the protective sleeve 21 on the side away from the power cord 13.

[0025] In this embodiment, the charger body 11 can be protected by providing the protective sleeve 21 outside the charger body 11, reducing the friction between the charger and other objects, avoiding scratches and abrasions, thereby prolonging the service life of the charger. The heat dissipation effect of the charger body 11 can be ensured through the provided heat dissipation grooves 22. The connection stability between the charger body 11 and power supply devices such as sockets or power strips can be enhanced through the provided suction cups, ensuring that the charger body 11 will not easily fall off due to external forces during use.

[0026] The present utility model provides a fastening device for a charger, and the specific working principle is as follows:

[0027] When the staff needs to perform anti - detachment fastening between the power cord 13 and the charger body 11, first, pull the two pull rods 113 respectively. These two pull rods 113 will respectively drive the movable column 110 and the latch 112 to move in the direction of the applied force. When the two pull rods 113 are pulled, the movable column 110 and the latch 112 will move along the direction of the applied force. This movement will cause the latch 112 to slide into the installation groove 19 and squeeze the spring 111. Insert the power plug 14 into the interface 12 through the positioning block 15 and the positioning groove 18. When the end of the power plug 14 is completely inserted into the interface 12, the staff can release the pull rods 113. At this time, the spring 111 will lose the acting force and then release the elastic force to push the latch 112 to be clamped in the fixing hole 16. Therefore, the power plug 14 and the charger body 11 will be limited and fixed, achieving the anti - detachment fastening effect.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
