Figure 2 is a schematic view of an embodiment of the invention applied to a watch case.
Fig. 3 is an exploded view of the structure of the embodiment of the present invention.
Detailed Description
Referring to the drawings, the tape threading electronic terminal applied in the present embodiment takes a watch as an example, and the push type latch mechanism of the present invention is used as a connection structure of a watch case and a watch chain. The watch case comprises an upper case 101 and a lower case 102.
The push type locking mechanism comprises a button 1 and a lock rod 2; the push type locking mechanism further comprises a guide through hole 3 which is arranged on the lower shell 102 and matched with the lock rod 2, the lock rod 2 penetrates through the guide through hole 3, and in a normal state, the front end of the lock rod 2 is exposed out of the front end of the guide through hole 3 to lock the watch chain. The rear end of the lock rod 2 is exposed out of the rear end of the guide through hole.
The push type locking mechanism further comprises a spring arm 4, one end of the spring arm 4 is installed outside the guide through hole 3, for example, on the spring seat 40 on the lower shell 102, and the other end of the spring arm is connected with the rear end of the lock rod 2.
The force between the push button 1 and the lock lever 2 configured to be inputted by pressing the push button 1 has a component force pushing the lock lever 2 backward. As a means capable of being adapted to various applications, a protrusion 20 may be provided at a rear portion of the lock lever 2 to a side, and the protrusion 20 may be used as a part to which a button pressing force is inputted, so that an angle of the protrusion 20 may be freely changed to adapt to space and angle restrictions of an application object with respect to an angle and a position between the lock lever 2 and the button 1.
The spring arm 4 and the lock rod 2 are configured such that the elastic force of the spring arm 4 has a forward component on the lock rod 2.
The spring arm 4 adopts a bent wire spring, namely a non-spiral spring, the bent wire spring is long and thin in size, small in occupied space and sufficient in elasticity, and the spring arm can adapt to various special-shaped narrow spaces by arranging the end parts without specially configured regular running space, so that the space utilization rate is improved. If the elastic force needs to be increased, a plurality of bent wire springs can be arranged in parallel. A connection hole 21 is formed at the rear of the lock lever 2, and an end 41 of the spring arm 4 is bent and inserted into the connection hole 21 to be connected to the lock lever 2.
The button 2 acts on the acted-on part through a connecting structure. Connection structure adopts rotatable connecting rod 5, the first end of connecting rod 5 rotates with the fixing base 6 of installation on epitheca 101 to be connected, the middle part of connecting rod 5 is as corresponding the position of accepting the pressing force with button 1, the second end of connecting rod 5 corresponds and promotes the position of locking lever as with the locking lever rear portion, and like this, connecting rod 5 is less than the arm of force to locking lever 2 to the arm of force of button 1 to can enlarge the stroke, provide better operation sensitivity.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
