Technical Field
[0001] The utility model relates to umbrella parts and umbrellas, in particular to a novel pinless locking rod lower disc, an umbrella rod and an umbrella. Background Art
[0002] At present, the lower disc of a traditional umbrella generally uses a pin to pass a pressing plate through the lower disc, and locks the umbrella rod through a lock block on the pressing plate. In this way, for production and manufacturing, the installation procedure of the pin will be increased. After the installation is completed, the two ends of the pin need to be sealed. For example, generally, the ends are sealed by being knocked flat. By knocking the two ends of the pin, it is deformed and closely attached to the surface of the connecting part, thereby fixing the pin. In addition, when the umbrella is used for a long time, the sealing ends of the two ends of the pin may be damaged, resulting in the failure of the pin, that is, falling off.

[0024] The present utility model will be further described in detail with reference to the accompanying drawings and specific embodiments.
[0025] As Figures 1-5 shown, a new type of pinless lock rod lower disk includes a lower disk body 100. An embedding groove 110 is provided on the lower disk body 100. A pressing plate 120 is provided in the embedding groove 110. The pressing plate 120 is rotatably connected to the inner side wall of the embedding groove 110;
[0026] Below one end of the pressing plate 120, there is a receiving groove 121 for receiving a return spring 122. Below the other end of the pressing plate 120, there is a lock block 123 which is matched with a lock hole on the umbrella rod. For example, after the umbrella is opened, the lock block 123 extends into the lock hole of the umbrella rod to lock the lower disk on the umbrella rod, so as to keep the umbrella in an opened state;
[0027] As Figure 2 and Figure 3 shown, one protrusion 124 is provided on each side of the pressing plate 120. Correspondingly, a pair of rotating holes 111 are provided on the inner side wall of the embedding groove 110. The protrusion 124 of the pressing plate 120 penetrates into the rotating hole 111 of the embedding groove 110, which can facilitate pressing the protrusion 124 into the through hole 111 of the embedding groove 110 for convenient installation.
[0028] In addition, further, as Figure 5 shown, the end of the protrusion 124 has a wedge-shaped surface which faces downward of the pressing plate 120. The inclination angle α of the wedge-shaped surface of the protrusion 124 (see the schematic diagram of the inclination angle α in Figure 5 ) is 60 degrees to 80 degrees. For example, it can be set to 70 degrees.
