Technical Field

[0001] The utility model relates to the technical field of voltage output conversion devices, and specifically relates to a portable voltage output conversion device. Background Technique

[0002] A voltage output conversion device is also called a voltage converter. The power supply voltages of power grids in different countries and regions may be different. When carrying a device from one region to another region with a different voltage standard, the voltage converter can make the device adapt to the new voltage environment. A voltage converter is an electronic device used to convert the input voltage into different output voltages. In practical applications, there are various types of voltage converters, such as AC to AC, DC to DC, AC to DC, etc. The working principle of a voltage converter usually based on a transformer, an electronic circuit, or a combination of both. The transformer changes the magnitude of the voltage through the principle of electromagnetic induction, while the electronic circuit can achieve more precise and complex voltage conversion functions.

Detailed Description of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a portable voltage output conversion device, which includes a converter body 1. Two groups of card slots 2 are fixedly installed at the bottom on one side of the converter body 1, and the openings of the card slots 2 face downward. It also includes a support assembly for supporting the converter body. The support assembly includes a bottom plate 4, and two groups of clamping blocks 5 that cooperate with the card slots 2 are fixedly installed on both sides of the top of the bottom plate 4.

[0029] By setting the card slots 2 and the clamping blocks 5, the converter body 1 can be quickly connected to the bottom plate 4 to prevent the converter body 1 from sliding; a support plate 10 is integrally formed on one side of the bottom plate 4, and the support plate 10 abuts against the bottom of the converter body 1. By setting the support plate 10, it can play a supporting role for the converter body 1, reduce the pressure on the clamping blocks 5, and thus improve the service life of the clamping blocks 5.

[0030] It also includes a waist belt for fixing to the waist. The waist belt includes a first fixing belt 7 and a second fixing belt 8. By setting the first fixing belt 7 and the second fixing belt 8, the bottom plate 4 can be fixed to the waist of the operator, and the converter body 1 can be supported by the core strength of the operator's waist and abdomen, thereby reducing the labor intensity and avoiding the influence of arm fatigue on other work.

[0031] Two groups of fixing slots 6 are opened on both sides of the bottom plate 4. One ends of the first fixing belt 7 and the second fixing belt 8 are fixed to the fixing slots 6 through fixing blocks 9. The fixing blocks 9 are fixed in the fixing slots 6 by screws. Tooth teeth 11 are integrally formed on one side of the fixing slots 6 and the fixing blocks 9, and the tooth teeth 11 of the fixing slots 6 and the fixing blocks 9 are engaged with each other.

[0032] By setting the fixing slots 6 and the fixing blocks 9, the first fixing belt 7 and the second fixing belt 8 can be connected to the bottom plate 4, and by setting the tooth teeth 11, the friction force can be increased, thereby improving the connection stability; the other end of the first fixing belt 7 is fixedly installed with a connection slot 12, the other end of the second fixing belt 8 is wound and fixed to the first D-ring 13, the first D-ring 13 is fixedly connected to the connection head 14, and the connection head 14 is clamped in the connection slot 12.

[0033] By setting the connection slot 12 and the connection head 14, the belt can be simply and quickly fixed to the operator's waist. When used in conjunction with the first D-ring 13, the length of the belt can be adjusted to adapt to different waist sizes.

[0034] A back plate 15 is fixedly installed in the middle of the top of the bottom plate 4. By setting the back plate 15, it is prevented that the operator's back directly contacts the converter body 1, avoiding the heat of the converter body 1 with a relatively high temperature after just being used from being transferred to the back and causing discomfort to the operator.

[0035] Two groups of second D-rings 16 are fixedly installed at the top of one side of the back plate 15. One end of a connecting belt 17 is wound and fixed inside the second D-ring 16. The other end of the connecting belt 17 is fixedly connected to a locking ring 18. Two groups of clamping columns 3 are fixedly installed on one side of the top of the converter body 1. A locking hole 19 that cooperates with the clamping column 3 is formed on the surface of the locking ring 18.

[0036] By setting the second D-ring 16, the length of the connecting belt 17 can be adjusted, so as to facilitate the connection between the locking ring 18 and the clamping column 3, and also facilitate the tightening of the connecting belt 17 after connection, thereby improving the connection stability between the converter body 1 and the support device.

[0037] An inner cavity is formed inside the locking ring 18. A locking tongue 20 is slidably installed in the inner cavity. Both sides of the locking tongue 20 are fixedly connected to a pressing plate 22 through a sliding rod 21. The pressing plate 22 is arranged outside the locking ring 18. The sliding rod 21 is slidably matched with the locking ring 18. A spring 23 is slidably sleeved on the surface of the sliding rod 21. One end of the spring 23 is fixedly connected to the locking tongue 20, and the other end of the spring 23 is fixedly connected to the inner wall of the locking ring 18.

[0038] By setting the spring 23, the locking tongue 20 can be pulled to tightly press against the clamping column 3 for locking. And by setting the pressing plate 22, the locking tongue 20 can be pushed through the sliding rod 21 to unlock the clamping column 3, so as to facilitate the operator to connect and remove the converter body 1.

[0039] During specific use, move the device to the designated position. When it is necessary to carry and transfer the converter body 1, move the structures such as the bottom plate 4 and the belt to the operator's waist. Adjust the length of the second connecting belt 17 through the first D-ring 13, and then snap the connection head 14 into the connection slot 12;

[0040] Fix the first fixing belt 7 and the second fixing belt 8 on the operator's waist, lift the converter body 1, align the card slot 2 with the clamping block 5, and lower the converter body 1 so that the clamping block 5 snaps into the card slot 2. At the same time, the bottom of the converter body 1 abuts against the surface of the support plate 10;

[0041] Lengthen the lengths of the two sets of connecting bands 17 through the second square buckle 16, then move the locking ring 18, align the locking hole 19 with the clamping post 3, and move downward. The spherical top surface of the clamping post 3 pushes the locking tongue 20 to open the locking hole 19. As the spherical surface passes through the locking hole 19, the spring 23 pulls the locking tongue 20 back to its original position and presses the locking tongue 20 against the bottom of the clamping post 3, thereby connecting the locking ring 18 and the clamping post 3;

[0042] Then tighten the connecting bands 17 through the second square buckle 16 and perform the same operation on the other set of locking rings 18, that is, complete the connection between the converter body 1 and the operator's waist.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
