Quick positioning device of connecting shaft in cover plate shaft sleeve

Abstract

The invention discloses a quick positioning device of a connecting shaft in a cover plate shaft sleeve. The quick positioning device comprises a cover plate shaft sleeve and a connecting shaft sleeved in the shaft sleeve, wherein a positioning through hole is arranged in a radial direction of the shaft sleeve; an elastic pin device is arranged in the radial direction of the connecting shaft; the elastic pin device consists of a positioning pin and an elastic piece connected between the positioning pin and the connecting shaft; the positioning pin is elastically plugged and buckled with the positioning through hole. In the process of sleeving the shaft sleeve axially, the positioning pin automatically ejects and is inserted into the positioning through hole when the positioning pin is aligned with the positioning through hole, so that the connecting shaft cannot axially slide in the shaft sleeve. When the connecting shaft needs be taken out from the shaft sleeve, the positioning pin is pressed to retract by the positioning through hole, so that the positioning pin and the positioning through hole are staggered to take out the connecting shaft quickly. Compared with the positioning structure of current cover plate shaft sleeve and connecting shaft, the positioning and connecting structure provided by the invention is simpler, more rapid and reliable in positioning and connection as well as detachment and separation of the shaft sleeve and the connecting shaft, and lower in manufacturing cost.

Description

technical field [0001] The invention relates to a quick-installation and positioning device for parts in a shaft sleeve at the rear end of a bathroom toilet cover, in particular to a quick positioning device for a connecting shaft in a cover shaft sleeve. Background technique [0002] The main positioning and connection methods of the connecting shaft in the shaft sleeve at the rear end of the existing toilet cover are: ① As disclosed in the Chinese utility model patent (CN201213769) for the installation structure of the slow-falling toilet cover, the 3 sets of mounting holes of the shaft sleeve 1.1 are provided with The connecting shaft 5 is provided with an annular groove 5.1, and the shaft sleeve 1.1 is provided with a bayonet 1.2 corresponding to the annular groove 5.1, and a lock 6 is engaged in the bay 1.2, and the end of the lock 6 is in the In the ring groove 5.1, the connecting shaft 5 is positioned and connected in the sleeve 1.1; this connection method needs to ma...

Problems solved by technology

[0002]The main positioning and connection methods of the connecting shaft in the shaft sleeve at the rear end of the existing toilet cover are: ① such as the slow-falling toilet disclosed in the Chinese utility model patent (CN201213769) The installation structure of the cover plate, the installation hole 3 of the shaft sleeve 1.1 is provided with a connecting shaft 5, the connecting shaft 5 is provided with an annular groove 5.1, and the shaft sleeve 1.1 is provided with a bayonet 1.2 corresponding to the annular groove 5.1, and the bayonet 1.2 is engaged with lock catch 6, and the end of lock catch 6 is in the ring groove 5.1, so that the connecting shaft 5 is positioned and connected in the sleeve 1.1; this connection method needs to manually insert the connecting shaft 5 into the sleeve 1.1, And it is time-consuming and laborious to manually calibrate the ring groove 5.1 on the connecting shaft 5 and the bayonet 1.2 on the shaft sleeve 1.1 to be completely aligned, so that the lock 6 can be installed on the bayonet 1.2 and snapped into the connecting shaft in the shaft sleeve 1.1 5 in the annular groove 5.1 to complete the positioning connection between the connecting shaft 5 in the shaft sleeve 1.1 and the shaft sleeve 1.1

② Another example is a cover plate automatic reset and quick installation mechanism disclosed in the Chinese utility model patent (CN201164433). The button 5 is provided with a hook 5.1 fixed to it, and a spring 6 is provided in the cavity of the button 5. The fixed shaft 3 and the There is a hook platform 7 between the buttons 5, the hook part 5.2 can be engaged with the hook platform 7, one end of the spring 6 withstands the hook 5.1 platform to form a lock switch, and then the fixed shaft 3 is inserted into the cover bushing In 2, one end of the fixed shaft 3 is locked
