[0001] The utility model belongs to the technical field of printing processing, and particularly relates to a novel boss pin splicing mechanism. Background Art

[0002] A pin splicing mechanism is a mechanical device used to connect and fix two or more components. This mechanism is widely used in various industrial fields, such as machinery manufacturing, construction, furniture manufacturing, etc. The pin splicing mechanism tightly connects different components together through pins (usually cylindrical or conical metal parts), providing stable structural support and reliable connection performance. During the printing process, a boss pin splicing mechanism is required to install and fix the equipment needed for printing on the frame.

[0003] In the existing boss pin splicing mechanism, the female end and male end of the pin are respectively installed on the frame and the equipment to be installed and fixed. Then, the equipment to be installed is moved to align the holes on the female end and male end components and insert them after ensuring the hole positions. After ensuring that the female end and male end are fully inserted, the operator aligns the tightening bolts with the holes on the female end and male end components and then uses external tools to turn the tightening bolts to tighten the connection between the female end and male end components, thus realizing the splicing of the novel boss pins. However, during actual use, the operator holds the installation equipment during installation and needs to ensure the positions of the holes on the female end and male end components and that the pins fully enter the holes and are in place before turning the tightening bolts. This requires a certain amount of time and effort from the operator, bringing great inconvenience to the installers. Content of the Utility Model

Specific embodiments

[0020] To better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with embodiments. However, the protection scope of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] As Figure 1 , 2 shown, it includes the female end 101 of the stud pin and the male end 201 of the stud pin. A taper pin 102 is provided at the top of the female end 101 of the stud pin. A taper groove 205 is provided at the inner bottom end of the male end 201 of the stud pin. The taper pin 102 is installed in cooperation with the taper groove 205. A first thread groove 103 is provided in the middle of the inner part of the female end 101 of the stud pin. A second thread groove 202 is provided in the middle of the inner part of the male end 201 of the stud pin. A first tightening bolt 104 is threadedly connected inside the first thread groove 103. A second tightening bolt 203 is threadedly connected inside the second thread groove 202. A limit fixing module for limit fixing is provided between the female end 101 of the stud pin and the male end 201 of the stud pin.

[0022] As Figure 2 shown, a thread groove 204 is provided inside the second tightening bolt 203. A stud 105 is provided at the top of the first tightening bolt 104. The stud 105 is threadedly connected with the thread groove 204.

[0023] As Figure 3 , 4As shown in the figure, the limit fixing module includes positioning pins 302 evenly arranged at the bottom end of the stud end 201. A plurality of evenly distributed positioning grooves 301 are provided at the bottom end of the stud mother end 101. The positioning pins 302 are respectively installed in cooperation with the adjacent positioning grooves 301. Sliding grooves 303 are provided on the side walls of the positioning grooves 301. Limit pins 304 are slidably arranged inside the sliding grooves 303. Limit grooves 305 are provided at the bottom ends of the positioning pins 302. The limit pins 304 are respectively installed in cooperation with the adjacent limit grooves 305. A driving unit for driving the limit pins 304 to move is also provided on the sliding grooves 303. T-shaped rubber blocks 306 are arranged inside the sliding grooves 303. The T-shaped rubber blocks 306 are respectively installed in cooperation with the adjacent limit pins 304. Lubricating oil is provided on the inner walls of the positioning grooves 301.

[0024] As Figure 1 , 2 shown in the figure, a plurality of evenly distributed rubber pads 106 are provided at the top end of the stud mother end 101.

[0025] When splicing is required, the operator installs the stud mother end 101 and the stud end 201 on the frame and the equipment to be installed and fixed respectively, and then moves the equipment to be installed and fixed closer to the frame, so that the stud end 201 approaches the stud mother end 101. The tapered pin 102 of the stud mother end 101 is inserted into the tapered groove 205 of the stud end 201. At this time, the positioning pins 302 are respectively inserted into the adjacent positioning grooves 301. When the positioning pins 302 are inserted into the positioning grooves 301, sliding occurs between the bottom end of the positioning pins 302 and the limit pins 304, so that the positioning pins 302 drive the limit pins 304 to slide into the inside of the sliding grooves 303. At this time, the T-shaped rubber blocks 306 are in a compressed state. After the positioning pins 302 are completely inserted into the positioning grooves 301, the limit pins 304 approach the positioning pins 302 again under the resilience of the T-shaped rubber blocks 306 and are inserted into the positioning grooves 301 inside the positioning pins 302, so as to limit and fix between the stud mother end 101 and the stud end 201. The rubber pads 106 on the stud mother end 101 can effectively prevent abrasion between the stud mother end 101 and the stud end 201 during connection and fixation.

[0026] The operator aligns the tightening bolt two 203 with the thread groove two 202 of the stud end 201 and then turns the tightening bolt two 203 with an external tool, so that the tightening bolt two 203 is screwed into the inside of the stud end 201. The operator aligns the tightening bolt one 104 with the thread groove one 103 of the stud mother end 101 and then turns the tightening bolt one 104 with an external tool, so that the tightening bolt one 104 is screwed into the inside of the stud mother end 101. When the tightening bolt one 104 is screwed into the stud mother end 101, the stud 105 is screwed into the inside of the thread groove 204, so as to connect and fix between the tightening bolt one 104 and the tightening bolt two 203, and further connect and fix between the stud mother end 101 and the stud end 201.

[0027] According to another embodiment of the present utility model, as Figure 1 , 2 shown, anti-corrosion coatings are provided on the outer sides of the female end 101 and the male end 201 of the dowel pin. During use, the anti-corrosion coatings provided on the outer sides of the female end 101 and the male end 201 of the dowel pin can effectively reduce the wear of the female end 101 and the male end 201 of the dowel pin during long-term use, and effectively increase the service life of the female end 101 and the male end 201 of the dowel pin.
