Description

Technical Field

[0001] The utility model relates to the technical field of voltage-stabilized power supplies, in particular to an anti-interference voltage-stabilized power supply. Background Art

[0002] A voltage stabilized power supply is an electronic device used to convert unstable input voltage into a precisely controlled and stable output voltage. It can be used in various electronic devices and machines to enable them to work normally. When an interference signal occurs in the circuit, a large current shock wave will be generated. At this time, an anti-interference voltage stabilized power supply is needed.

[0003] The prior art discloses patent application number "CN201920209684.4", a vehicle-mounted AC regulated power supply, which includes a power module, a main box body, an upper cover, a panel, a back plate and two mounting plates. By setting the main box body, the upper cover, the panel, the back plate and the two mounting plates, the main box body has only three openings, and the upper cover, the panel and the back plate respectively close the three openings. The power module is installed in a confined space enclosed by the main box body, the upper cover, the panel and the back plate. Since the main box body is not a fully sealed structure, it can be easily disassembled and installed.

However, in actual use, some larger voltage-stabilized power supplies will have universal wheels installed at the bottom. In this way, the voltage-stabilized power supply will generate certain vibrations when moving. At this time, the amplitude of the vibration force is too large to easily damage the electrical components inside the voltage-stabilized power supply, affecting the safety of the voltage-stabilized power supply during use and making it inconvenient to use.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5As shown, an anti-interference voltage-stabilized power supply comprises a base 1, four first dampers 2 are installed on the upper end surface of the base 1, and the upper end surfaces of the four first dampers 2 are fixedly connected with a top seat 4, and four universal wheels 3 are respectively installed on the lower end surface of the base 1, and a voltage-stabilized power supply body 5 is fixedly provided on the upper end surface of the top seat 4. Through the setting of the universal wheels 3, the base 1 can drive the voltage-stabilized power supply body 5 to move to the use location by using the universal wheels 3, without manual handling and moving, and the operation is convenient and labor-saving, and a second connection spring 9 is connected in an array between the top seat 4 and the base 1;

[0027] Four vertical plates 6 are fixedly installed on the upper end surface of the base 1, and two stabilizing blocks 7 are connected to the two ends of the top seat 4. Through the installation and use of the vertical plates 6 and the stabilizing blocks 7, the stabilizing blocks 7 can slide up and down inside the vertical plates 6 to limit the moving trajectory of the top seat 4, so that the entire voltage-stabilized power supply can buffer vibration more stably and better protect the voltage-stabilized power supply. A first connecting spring 8 is connected between the four stabilizing blocks 7 and the base 1, and two connecting rods 10 are fixedly connected inside the top seat 4. Two clamping slides 11 are slidably connected to the outer surfaces of the two connecting rods 10. The clamping slide 11 is used to fix the voltage-stabilized power supply body 5. Two No. 1 connecting springs 12 are installed between the two clamping slides 11 and the top seat 4, and a filter 24 is installed inside the voltage-stabilized power supply body 5.

[0028] One side of the No. 1 connecting spring 12 is connected to the inner side of the clamping slide 11, and the other side of the No. 1 connecting spring 12 is connected to the inside of the top seat 4. The upper end surfaces of the two clamping slides 11 are clamped with two L-shaped limit plates 13, and the inner sides of the four L-shaped limit plates 13 are connected to the No. 2 connecting springs 14. The inner sides of the four No. 2 connecting springs 14 are fixedly connected with positioning baffles 15, and the positioning baffles 15 are used to fix the voltage-stabilized power supply body 5.

[0029] Two transverse plates 111 are fixedly installed on the upper end surface of the voltage-stabilized power supply body 5, and the front end surfaces of the two transverse plates 111 are slidably connected with embedded plates 16. The upper end surfaces of the two embedded plates 16 are installed with second dampers 17, and the upper end surfaces of the two second dampers 17 are fixedly connected with protective top frames 18.

[0030] Two movable plates 20 are rotatably connected to the two ends of the protective top frame 18. Through the setting of the movable plates 20, the two movable plates 20 can be blocked at the heat dissipation port of the voltage-stabilized power supply to prevent rainwater from entering the interior of the voltage-stabilized power supply and protect the internal electrical components. A third connecting spring 19 is connected in an array between the two embedded plates 16 and the protective top frame 18. One side of the third connecting spring 19 is connected to the upper end surface of the embedded plate 16, and the other side of the third connecting spring 19 is connected to the lower end surface of the protective top frame 18.

[0033] The working principle of an anti-interference regulated power supply provided by the utility model is as follows:

[0034] By placing the voltage-stabilized power supply body 5 onto the top seat 4 equipped with the first damper 2, the voltage-stabilized power supply body 5 will squeeze the two clamping slides 11 equipped with the No. 1 connecting spring 12, so that the elastic force of the No. 1 connecting spring 12 can be used to allow the two clamping slides 11 to be adaptively clamped and fixed to the front and rear sides of the voltage-stabilized power supply, and then the four L-shaped limit plates 13 are respectively connected to the two clamping slides 11, so that the four positioning baffles 15 equipped with the No. 2 connecting spring 14 at the L-shaped limit plate 13 can be elastically clamped to the left and right sides of the voltage-stabilized power supply, thereby firmly positioning the entire voltage-stabilized power supply to ensure the stability of the voltage-stabilized power supply when in use, and then the first damper 2 can be used to weaken the vibration force generated when the universal wheel 3 is used to move the entire voltage-stabilized power supply, and the first connecting spring 8 and the second connecting spring 9 can be used to further elastically buffer the vibration force, which is beneficial to buffer and protect the entire voltage-stabilized power supply and improve the safety of the voltage-stabilized power supply when in use. At the same time, the filter 24 can filter out the interference signal of the voltage-stabilized power supply;

[0035] By inserting the two embedded plates 16 into the interior of the two transverse plates 111, the protective top frame 18 installed with the second damper 17 and the third connecting spring 19 is assembled above the voltage-stabilized power supply body 5, and then the four rotating plates 22 are rotated upward in turn to release the limit on the two movable plates 20, so that the two movable plates 20 can be rotated downward, so that the two movable plates 20 can be protected on the left and right sides of the voltage-stabilized power supply body 5. At this time, the protective top frame 18 and the movable plates 20 can play a role in rain protection and are used to protect the entire voltage-stabilized power supply. At the same time, the second damper 17 and the third connecting spring 19 can be used to give the protective top frame 18 the ability of elastic buffering, so as to increase the protection of the voltage-stabilized power supply.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
