Embodiment Construction
[0021] The present invention will be further explained below in conjunction with the accompanying drawings.
[0022] like figure 1 , figure 2 As shown, a push-push telescopic device includes a guide groove cover, a spring, and a telescopic rod. A section of guide groove is provided on the inner wall of the guide groove cover. The starting end of the guide groove is close to the port of the guide groove cover, and the terminal end of the guide groove is far away from the port of the guide groove cover. The point groove, the depth of the stagnation point groove is greater than the depth of the guide groove, and the connection between the stagnation point groove and the guide groove is a smooth arc. The guide groove is an arc-shaped groove extending from the starting end to the terminal end with an arc less than or equal to 360°, and the distance from the farthest end of the arc-shaped groove along the axial direction of the guide groove sleeve to the port of the guide groove ...

The invention discloses a push-push type telescope device. The push-push type telescopic device comprises a guide groove sleeve, a spring and a telescopic rod; at least one guide groove is formed in the inner side wall of the guide groove sleeve, the starting ends of the guide grooves are close to the end opening of the guide groove sleeve, and the finishing ends of the guide grooves are far awayfrom the end opening of the guide groove sleeve; a standing point groove is formed in the finishing ends of the guide grooves, and the guide grooves are arc-shaped grooves extending from the startingends to the finishing ends; the distance between the farthest end of the arc-shaped grooves in the axis direction of the guide groove sleeve and the end opening of the guide groove sleeve is larger than the distance between the standing point groove and the end opening of the guide groove sleeve, and the radian of the guide groove section between the farthest end of the arc-shaped grooves in the axis direction of the guide groove sleeve and the standing point groove is smaller than 180 degrees; and the spring is located in the guide groove sleeve, the telescopic rod penetrates into the guide groove sleeve from the end opening of the guide groove sleeve, and a guide pin matched with the guide grooves is arranged on the side surface of the telescopic rod.
Description
technical field [0001] The invention relates to a connection device, in particular to a push type telescopic device. Background technique [0002] Existing push-push type retractable devices are many, such as mobile phone card slots, power switches and the like. The push-push telescopic device has a single movement direction, easy installation and simple appearance. In the special position where it is inconvenient to use force from both directions, this connection form makes the installation very convenient. However, most of the existing devices are used in precision equipment in the electronics and electrical industries, and the devices are small, complex in structure and high in cost. Contents of the invention [0003] Purpose of the invention: Aiming at the above-mentioned prior art, a push-type telescopic device is proposed, which can be used as a large-scale construction operation. [0004] Technical solution: A push-push telescopic device, including a guide slot c...
