Problems solved by technology

[0004] However, due to the thin wall of the housing hole of the electronic device, the push button of the push key is very small, and it is easy to break away from the housing hole. After the base is fixed, the push key will be stuck between the housing and the base, resulting in Product scrapping, wasting resources

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] see image 3 , Figure 4 and Figure 5 A push button assembly 100 provided in the first embodiment of the present invention includes a push button 10 and a seat 20 . The movement trajectory of the push button 10 is an arc concentric with the matching lens barrel. Preferably, the push button 10 and the seat body 20 are roughly rounded in shape. Since the movement track of the push button is an arc concentric with the lens barrel, it is difficult for the shift fork to be separated from the focusing lever when it moves.

[0017] The push key 10 includes a push button 11 , a key board 12 , a shift fork 13 and a blocking piece 14 . The keypad 12 has an outer arc surface 12a, an inner arc surface 12b, and a side surface 12c parallel to the movement track of the push key. The blocking piece 14 has a connecting portion 140 and an engaging portion 141 . T...

Abstract

The invention provides a push key component which comprises a push key and a base. The push key is provided with a key panel, a push button, and a transmission fork. The base is provided with a runner and at least a spacing groove. The runner and the spacing groove are arranged on two surfaces which the base is opposite to. The spacing groove is communicated with the runner. The spacing groove runs through the side of the base. The side is parallel to the glide direction of the push key. The key panel is contained in the runner. The transmission fork is exposed by the runner and the spacing groove. The key panel is provided with at least a separation blade which is provided with an interconnecting piece and a blocking part. The separating blade is connected with the key panel by the interconnecting piece. The blocking part is extended out of the side of the key panel and blocked in the spacing groove. As the push key is blocked in the base in advance, the deviation does not happen when the push key is in the position of a groove of a shell and the base in fixation, the push key is blocked in the position after fixation to cause product abandonment.

Description

technical field [0001] The invention relates to the field of photography, in particular to a push button assembly for lens focusing. Background technique [0002] see figure 1 and figure 2 , is a traditional focusing push key assembly 1, which includes a push key 2 and a seat body 3, and the push key 2 has a push button 2a, a key plate 2b, and a shift fork 2c, and the shift fork 2c is a bifurcated shift fork, and the base body 3 is provided with a slide groove 3a, and the shift fork 2c can slide in the slide groove 3a. [0003] The push button 2 and the seat body 3 in the push button assembly 1 are separate structures. When the push button assembly 1 is assembled, the push button 2a of the push button 2 needs to be placed in the housing hole 6a of the electronic device, and then the The seat body 3 is pressed on the push key 2 , and then the seat body 3 is pressed on the housing 6 by hot pressing, and the push key 2 is accommodated between the housing 6 and the seat body...
