DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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. Example

[0023] See also Figures 1 to 4 , is the first embodiment of the present utility model, which provides a technical solution: a portable splicing universal PCB circuit board, including

[0024] Two universal PCB circuit board bodies 1, a left end bar 2 provided on the left surface of the universal PCB circuit board body 1, a right end bar 3 provided on the right surface of the universal PCB circuit board body 1, cylindrical sockets 6 provided on the surfaces of the left end bar 2 and the right end bar 3, and splicing pins 4 inserted into the inner sides of the cylindrical sockets 6. The left end bar 2 and the PCB circuit board body 1 are integrally formed, and the right end bar 3 is also integrally formed with the PCB circuit board body 1.

[0025] The left top and right bottom of the universal PCB circuit board body 1 are both provided with a blocking and limiting mechanism 5. The blocking and limiting mechanism 5 includes a limiting baffle 51 rotatably mounted on the surface of the universal PCB circuit board body 1, and the end of the limiting baffle 51 extends to the cylindrical socket 6 to cover the cylindrical socket 6. The upper and lower limiting baffles 51 can be used to stably block and limit the splicing column 4 to ensure the plug-in stability of the left end bar 2 and the right end bar 3, thereby ensuring the stability of the two universal PCB circuit board bodies 1 after splicing. The blocking and limiting mechanism 5 also includes an inner rotation groove 52 opened inside the universal PCB circuit board body 1, and an inner rotation seat 53 is rotatably installed in the inner rotation groove 52. One end of the inner rotation seat 53 extends to the surface of the universal PCB circuit board body 1 and is fixed to the limiting baffle 51, so that the limiting baffle 51 can rotate smoothly.

[0026] Among them, the blocking and limiting mechanism 5 also includes a side groove 54 opened on the inner wall of the inner rotation groove 52, and a spring 55 and a telescopic card bead 56 are installed in the side groove 54. The surface of the inner rotation seat 53 is provided with two circular card grooves 57 corresponding to the telescopic card bead 56. The telescopic card bead 56 is movably installed in the side groove 54 through the spring 55, and the end of the telescopic card bead 56 pops out into one of the circular card grooves 57, thereby realizing the engagement and limitation of the inner rotation seat 53 and the limit baffle 51 during daily use.

[0027] One end of the spring 55 is fixed to the inner wall of the side groove 54 , and the other end of the spring 55 is fixed to the telescopic card bead 56 .

[0028] In summary, when two universal PCB circuit board bodies 1 are actually spliced ​​together, the left end bar 2 and the right end bar 3 are first fitted together, and the cylindrical sockets 6 on the surfaces of the two are aligned. Then, the splicing pin 4 is inserted into the cylindrical socket 6 to achieve the connection between the left end bar 2 and the right end bar 3. Then, the upper and lower limit baffles 51 are rotated toward the cylindrical socket 6, so that the inner rotating seat 53 rotates in the inner rotating groove 52. When the inner rotating seat 53 rotates, the end of the telescopic card bead 56 is squeezed back into the side groove 54 until the limit baffle 51 can be rotated to the cylindrical socket 6 and the cylindrical socket 6 is inserted. When the upper and lower limit baffles 51 are rotated to the surfaces of the right end bar 3 and the left end bar 2 respectively, the splicing pin 4 can be stably blocked and limited to complete the rapid splicing between the two universal PCB circuit board bodies 1. At the same time, since no external equipment and tools are required during the entire splicing process, it is convenient to carry with you during actual use, and no external equipment and tools are required, which makes it easy to use. Example

[0029] See also Figures 1 to 5, which is the second embodiment of the present utility model, is based on the previous embodiment, but differs in that the auxiliary positioning structure can be provided to assist in positioning the splicing column 4 after the splicing column 4 is inserted into the cylindrical socket 6.

[0030] Specifically, it also includes an auxiliary positioning structure, which is arranged between the splicing column 4 and the cylindrical socket 6. The auxiliary positioning structure includes a rubber side block 61 embedded in the inner wall of the cylindrical socket 6, a positioning protrusion 62 arranged on the surface of the rubber side block 61, and two positioning card grooves 41 opened on the surface of the splicing column 4. The positioning protrusion 62 is embedded in the positioning card groove 41, and the splicing column 4 can be assisted in positioning after the splicing column 4 is inserted into the cylindrical socket 6. When the splicing column 4 is inserted into the cylindrical socket 6, the positioning protrusion 62 will be squeezed first, causing the positioning protrusion 62 to undergo elastic deformation until the splicing column 4 is successfully inserted into the two cylindrical sockets 6. At this time, the positioning protrusion 62 will be squeezed into the positioning card groove 41, realizing auxiliary positioning of the splicing column 4, preventing the splicing column 4 from falling off from the cylindrical socket 6 at this time, bringing convenience to the subsequent limiting operation, and further improving the convenience of splicing.

[0031] Among them, the rubber side block 61 and the positioning protrusion 62 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. An elliptical cavity is provided in the rubber side block 61, so that the positioning protrusion 62 has sufficient deformation space when squeezed. A rectangular embedding groove is provided on the inner wall of the cylindrical socket 6, and the rubber side block 61 is installed in the embedding groove to realize the embedded installation of the rubber side block 61, so that the rubber side block 61 will not block the smooth insertion of the splicing column 4.

[0032] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
