AI Technical Summary
In the existing technology, push-type lock bodies cannot be used with rotary or fixed smart lock bodies, and cannot be unlocked by push-type.
Design a fixed handle for direct push unlocking. By setting an unlocking sliding block and a return spring inside the handle housing, the direct push unlocking is achieved by using a pressing part, and the anti-locking is achieved by controlling the rotation of the anti-lock bar with a rotating part.
It enables unlocking via a direct push method, featuring a simple structure, high stability, and ease of use. Both the inner and outer handles can be used for unlocking and locking.

Abstract
Claims
1. A fixed handle of straight push lock, comprising a handle housing, an upper end of the handle housing is shaped with a mounting cavity, characterized in that: An unlocking sliding block is provided inside the mounting cavity, which can slide up and down within the cavity. The unlocking sliding block is connected to a core rod that extends inwards out of the mounting cavity. The up-and-down movement of the unlocking sliding block causes the core rod to move up and down. A through groove is provided at the lower end of the mounting cavity, and the lower end of the unlocking sliding block extends downwards through the groove to form a pressing part. A limiting block is also provided inside the mounting cavity. The unlocking sliding block has a limiting end that matches the limiting block, which is located below the limiting end. A return spring is also provided inside the mounting cavity, with a positioning end. One end of the return spring is connected to the positioning end, and the other end is connected to the unlocking sliding block. The return spring always applies a downward force to the unlocking sliding block, causing the limiting end of the unlocking sliding block to abut against the limiting block.
2. A push-to-open deadlatch mortise handle according to claim 1, wherein: The mounting cavity opens inward, and a sealing plate is provided at the opening. The sealing plate has a moving groove for the core rod to move up and down.
3. A push-to-open deadlatch mortise handle according to claim 1, wherein: A spring groove is formed inside the mounting cavity. The upper end of the spring groove is the positioning end of the reset spring. The unlocking sliding block extends into the spring groove to form a reset end. The upper end of the reset spring abuts against the positioning end of the reset spring, and the lower end of the reset spring abuts against the reset end.
4. A push-to-open deadlatching overcentre handle according to claim 3, wherein: There are two spring slots, which are respectively set on the left and right sides of the mounting cavity. Each spring slot is equipped with a reset spring, and the unlocking sliding block extends a reset end toward each of the two spring slots.
5. A push-to-open deadlatching overcentre handle according to claim 4, wherein: A positioning block is also provided between the two spring grooves, and a positioning end is formed at the rear end of the unlocking sliding block, with the positioning block positioned above the positioning end.
6. A push-to-open deadlatching overcentre handle according to claim 1, wherein: The unlocking sliding block has a core hole formed in the middle, one end of the core rod passes through the core hole, and the other end of the core rod extends inward to the outside of the mounting cavity.
7. A push-to-open deadlatch mortise handle according to claim 1, wherein: The handle housing is also provided with a rotating groove, in which a rotating component is provided, and the rotating component is connected to a deadbolt bar, which extends inward out of the handle.
8. A push-to-open deadlatch mortise handle according to claim 7, wherein: The rotating component is a knob or a key core.
9. A push-to-open deadlatching overcentre handle according to claim 8, wherein: The rotating groove is also located inside the mounting cavity and above the unlocking sliding block, with the anti-locking bar extending inward out of the mounting cavity.
10. A push-to-open lever handle assembly, characterized by: The device includes two handles as described in claim 7, namely an outer handle and an inner handle. The outer handle and the inner handle share a core rod. One end of the core rod passes through the core hole of the unlocking sliding block of the outer handle, and the other end of the core rod passes through the core hole of the unlocking sliding block of the inner handle. The outer handle and the inner handle share a deadbolt bar. The rotating component of the outer handle is a key core, which is connected to the deadbolt bar. The rotating component of the inner handle is a knob, which is connected to the deadbolt bar.
