Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] According to an embodiment of the present utility model, a push rod handle is provided. Please refer to Figures 1 to 3, including: a push rod 1 and two door handles 2. Both ends of the push rod 1 are respectively connected to each door handle 2, and a receiving cavity 21 is provided on the door handle 2; two first fixing components 3, each first fixing component 3 is respectively located in each receiving cavity 21; the rotating rod 31 of the first fixing component 3 passes through the door and window profile 4 and is connected to a transmission 5 inside the door and window profile 4; pushing and pulling the push rod 1 causes the two door handles 2 on both sides to rotate accordingly, driving the rotating rod 31 to rotate relative to the door and window profile 4, thereby transmitting force to the transmission 5, so that the transmission 5 is connected to and disconnected from a lock block on the door and window frame, realizing the opening or closing of the door and window. The two sides of the push rod 1 are connected to the door handles 2, hiding the structures of the first fixing component 3 and the rotating rod 31 in the receiving cavity 21 of the door handle 2 and passing through the door and window profile 4 to be connected to the transmission 5, achieving a seamless connection between the door handle and the door and window profile, avoiding the problem of the protruding handle base in the traditional design, and making the appearance of the entire door and window more concise and beautiful. The user only needs to simply push and pull the push rod 1, and the rotation of the door handle 2 can drive the rotating rod 31 to rotate inside the door and window profile 4, and then transmit the force to the transmission 5 to realize the connection and disconnection with the lock block on the door and window frame. This design greatly simplifies the operation process and improves the convenience of use. The push-bar door handle of this embodiment solves the technical problem that the protruding handle bases on both sides of the push rod in the related art affect the aesthetics of the door and window.

[0028] Refer to Figure 1 and Figure 2 , for the push-bar door handle of this embodiment, the first fixing component 3 further includes a clamping block 32, and a clamping groove 22 matching the clamping block 32 is provided in the receiving cavity 21. The clamping block 32 is stuck in the clamping groove 22, and the door handle 2 drives the clamping block 32 to rotate, and the rotating rod 31 also rotates accordingly. The matching design of the clamping block 32 and the clamping groove 22 makes the connection between the first fixing component 3 and the door handle 2 tighter and more stable. The setting of the clamping block 32 increases the contact area between the first fixing component 3 and the door handle 2. Compared with only being connected by a simple rotating shaft or pin, the matching of the clamping block 32 and the clamping groove 22 can provide a larger connection area, making the force transmission more uniform and dispersed, and helping to reduce the local stress concentration phenomenon. When the door handle 2 is subjected to an external force (such as pushing and pulling the push rod 1), due to the tight fit between the clamping block 32 and the clamping groove 22, the door handle 2 can drive the clamping block 32 to rotate more effectively.

[0029] Participate in Figure 1 , for the push-bar door handle of this embodiment, a first through hole 41 is provided on the door and window profile 4, and the rotating rod 31 passes through the first through hole 41 and is connected to a transmission 5 on the other side of the door and window profile 4.

A second through-hole 42 is also provided on the door and window profile 4. The first fixing component 3 further includes a first fastener 34. The first fastener 34 sequentially passes through the reinforcement base 33 and the second through-hole 42 to fix the first fixing component 3 on the door and window profile 4. Through the support of the reinforcement base 33, the rotating rod 31 can maintain better stability when subjected to external forces, reducing deformation or damage caused by uneven stress. The first fastener 34 passes through the reinforcement base 33 and the second through-hole 42, firmly fixing the first fixing component 3 on the door and window profile 4. The double-fixing method greatly enhances the stability of the overall structure, ensuring that the handle can maintain stable performance during long-term use.
