Description

Technical Field

[0001] The utility model relates to a programming building block robot connector, belonging to the field of programming building block robot accessories. Background Art

[0002] The connector is one of the main accessories in the programming building block robot. It connects two adjacent parts in the programming building block robot. A plurality of plug-in tubes are installed on the surface of the connector, so that one end of the connecting shaft of the multiple parts in the programming building block robot is respectively inserted into the plurality of plug-in tubes to complete the plug-in connection of the multiple parts in the programming building block robot. At present, after the plug-in of one end of the connecting shaft and the plug-in tube, the connecting shaft and the plug-in tube rely on sliding friction to maintain the stability of the relative position. However, the reliability of sliding friction is poor, which may cause the connecting shaft and the plug-in tube to be detached. Therefore, it is necessary to design a programming building block robot connector that improves the plug-in stability of the connecting shaft and the plug-in tube. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a programming building block robot connector to solve the problems raised in the above-mentioned background technology. The utility model prevents the connection shaft from being separated from its plug-in components, thereby improving the stability of the structure.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a programming building block robot linker, comprising a hollow disk, a plurality of plug-in tubes are equidistantly installed in a ring shape on the annular side surface of the hollow disk, a rubber plug is inserted in the plug-in tube, a connecting shaft is installed on one side of the rubber plug, and the end of the connecting shaft away from the rubber plug extends to the outside of the plug-in tube, a vent is provided in the area of ​​the hollow disk covered by the plug-in tube, a circular opening is provided in the middle position of one side of the hollow disk, a straight cylinder is installed in the circular opening, the closed end of the straight cylinder extends into the hollow disk, a spring is installed in the lower position of the straight cylinder, a round cover for sealing the open end of the straight cylinder is installed on the upper end of the spring, a plurality of circular holes are equidistantly opened in a ring shape on the outer surface of the lower end of the straight cylinder, a cylinder ring for being inserted in the straight cylinder is installed on the lower surface of the hollow disk, and a plurality of exhaust holes are equidistantly opened in a ring shape on the annular side surface of the cylinder ring.

[0005] Furthermore, a rubber sleeve is sleeved on the cylinder ring, the rubber sleeve is adhered to the cylinder ring by glue, the outer diameter of the rubber sleeve is the same as the inner diameter of the straight cylinder, the rubber sleeve is slidably installed in the straight cylinder, and a plurality of through holes aligned with the exhaust holes are equidistantly opened in an annular shape on the annular side of the rubber sleeve.

[0006] Furthermore, a lower connecting plate is connected and fixed to the lower end of the spring, and the lower connecting plate is glued to the bottom of the straight tube by glue.

[0007] Furthermore, an upper connecting plate is connected and fixed to the upper end of the spring, and the upper connecting plate is adhered to the round cover by glue.

[0008] Furthermore, the open end of the straight tube is sleeved with a ring edge connected and fixed to the straight tube, and the ring edge is connected and fixed to the hollow disk by glue.

[0009] Furthermore, a conical head is fixedly connected to one end of the rubber stopper away from the connecting shaft, and the conical head and the rubber stopper are an integrally formed structure.

[0010] Furthermore, the plug-in tube and the hollow disk are integrally formed, the plug-in tube has a rectangular cross section, the rubber plug has a rectangular cross section, and the plug-in tube is arranged along the radial direction of the hollow disk.

[0011] Beneficial effects of the utility model:

[0012] 1. Under the limit of the spring, the round cover is used to seal the open end of the straight cylinder. After the rubber plug on the connecting shaft is inserted into the plug tube, the rubber plug squeezes the air in the plug tube into the hollow disk through the vent hole. At this time, the air pressure in the hollow disk increases due to the increase of air, and the air pressure in the straight cylinder increases, so that the round cover moves away from the straight cylinder under the action of the pressure difference, and the spring is stretched. At this time, the exhaust hole opened on the cylinder ring moves to the outside of the straight cylinder, so that the air in the hollow disk is discharged through the exhaust hole, and the excess air in the hollow disk is discharged. Under the action of the spring rebound force, the exhaust hole is moved back to the straight cylinder. At this time, the air no longer enters and exits the hollow disk at will. When the connecting shaft is pulled, the outside air cannot enter the hollow disk, so the connection shaft is prevented from separating from the plug tube, which improves the stability of the structure compared to the method of relying on sliding friction.

[0013] 2. The rubber sleeve is placed on the cylinder ring and the through hole is aligned with the exhaust hole, so that the rubber sleeve increases the sealing between the cylinder ring and the inner wall of the straight cylinder.

[0014] 3. Install the upper connecting plate and the lower connecting plate on both ends of the spring respectively, then use glue to stick the upper connecting plate and the round cover, and use glue to stick the lower connecting plate and the straight tube, so as to realize the convenient assembly of the spring, the round cover and the straight tube.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1 A rubber plug 3 is inserted in the plug-in tube 2, and a connecting shaft 4 is installed on one side of the rubber plug 3. The end of the connecting shaft 4 away from the rubber plug 3 extends to the outside of the plug-in tube 2. The end of the rubber plug 3 away from the connecting shaft 4 is connected and fixed with a conical head. The conical head and the rubber plug 3 are an integrally formed structure. The design of the conical head facilitates the insertion of the rubber plug 3 in the plug-in tube 2.

The closed end of the straight cylinder 10 extends into the hollow disk 1, and the open end of the straight cylinder 10 is sleeved with a ring edge 6 connected and fixed to the straight cylinder 10. The ring edge 6 is connected and fixed to the hollow disk 1 by glue. The design of the ring edge 6 increases the connection range between the straight cylinder 10 and the hollow disk 1.

[0025] See also Figure 2 and Figure 3A spring 9 is installed at the lower position inside the straight cylinder 10, and a round cover 5 for blocking the open end of the straight cylinder 10 is installed on the upper end of the spring 9, wherein a lower connecting plate 11 is connected and fixed to the lower end of the spring 9, and the lower connecting plate 11 is glued to the bottom of the straight cylinder 10 by glue, and an upper connecting plate 14 is connected and fixed to the upper end of the spring 9, and the upper connecting plate 14 is adhered to the round cover 5 by glue. The upper connecting plate 14 and the lower connecting plate 11 are respectively installed at both ends of the spring 9, and then the upper connecting plate 14 and the round cover 5 are adhered by glue, and the lower connecting plate 11 and the straight cylinder 10 are adhered by glue, so as to realize the convenient assembly of the spring 9, the round cover 5 and the straight cylinder 10.
