[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] See also Figure 1The present embodiment discloses a bidirectional push-pull handle mechanism, including two handle bodies 1 arranged opposite to each other. Both handle bodies 1 are arranged vertically, and their lower ends are respectively connected to rotating members 2, and are connected to mounting seats 3 through the rotating members 2. The two mounting seats 3 are arranged opposite to each other, and are connected to each other through long bolts and fixed to both sides of the door.

[0028] Specifically, Figure 2 As shown, the handle body 1 is fixedly provided with a protrusion 11 at its lower end, and the protrusion 11 is provided with a mounting groove 12 for connecting the rotating member 2. In this embodiment, the rotating member 2 is constructed as a connecting block structure, such as Figure 3 As shown, it includes a connecting end 22 and a rotating end 21 , the connecting end 22 is inserted into the mounting groove 12 and fastened with screws, and the rotating end 21 is installed in the mounting seat 3 .

[0029] Combination Figure 4-Figure 8 The mounting seat 3 includes a mounting shell 31 and a mounting top seat 32 and a mounting base 33 which are clamped in the mounting shell 31. The shapes of the mounting top seat 32 and the mounting shell 31 are adapted to each other. The mounting shell 31 is made of high-strength POM material with high strength and light weight. Its shape can be specifically set according to actual needs. The mounting shell 31 is used to protect internal accessories while ensuring the beauty of the appearance.

[0030] The mounting top seat 32 and the mounting base 33 are connected by screws, and the two cooperate to form an installation space, which is used to install a transmission assembly that cooperates with the rotation of the rotating member 2. The transmission assembly includes a mounting shaft 4 that is rotatably connected to the rotating member 2, and a paddle 5 connected to the rotating end 21 of the rotating member 2. For details, see Figure 4 The mounting base 33 is provided with two vertical plates 331 with a predetermined spacing on the side facing the mounting top seat 32, and the vertical plates 331 are provided with a first groove 332 adapted to the mounting shaft 4. Figure 5 The mounting top seat 32 is provided with a second groove 321 that matches the first groove 332, and the mounting shaft 4 is installed in the mounting circular hole formed by the first groove 332 and the second groove 321. The mounting shell 31 and the mounting top seat 32 are provided with a mounting opening 311 that matches the rotating member 2. The rotating end 21 of the rotating member 2 extends into the mounting opening 311 and further extends between the two vertical plates 331. The rotating member 2 is provided with a central through hole that rotates with the mounting shaft 4. The mounting shaft 4 is inserted into the central through hole so that the rotating member 2 is rotatably connected to the mounting shaft 4. A spacing should be left between the rotating member 2 and the mounting base 33 so that the rotating end 21 has room for movement. Pushing the handle inward or pulling the handle outward can drive the connecting end 22 of the rotating member 2 to move up and down, and then the rotating member 2 can use the mounting shaft 4 as a rotation fulcrum to make the rotating end 21 move up and down synchronously.

[0031] See again Figure 3 The rotating end 21 is provided with an opening groove 23 adapted to the paddle 5 on the side facing the mounting base 33. The paddle 5 extends into the opening groove 23, and one end thereof is rotatably connected to the mounting shaft 4. The rotating end 21 can drive the paddle 5 to move synchronously by moving up and down.

[0032] See again Figure 4 The mounting base 33 is provided with a long hole 333 through which the paddle 5 can pass. The long hole 333 is arranged along the movement direction of the paddle 5, and its height should be greater than the width of the paddle 5, so that the paddle 5 has space to move up and down.

[0033] See also Fig. 9 , Fig.10 In this embodiment, the transmission assembly further includes an upper shift block 6 and a lower shift block 7 installed in the door lock panel 101. The upper shift block 6 and the lower shift block 7 are used to cooperate with the lock tongue driving structure 8 to control the movement of the lock tongue. The lock tongue driving structure 8 belongs to the prior art and has nothing to do with the technical problem solved by this solution. Therefore, this structure is not described in detail in this embodiment.

[0034] Specifically, the upper shift block 6 and the lower shift block 7 are arranged opposite to each other in the upper and lower parts, and both are rotatably connected to the door lock panel 101 through the rotating shaft 9. The upper shift block 6 is roughly in an oblong structure, and its two ends are respectively a first connection end 61 and a second connection end 62. The first connection end 61 is used to connect the door lock panel 101, and the second connection end 62 is provided with a protruding shaft 63 for connecting the bolt driving structure 8. The bottom end of the upper shift block 6 is also fixed with a first blocking block 64 near the first connection end 61. The two ends of the lower shift block 7 are respectively a third connection end 71 and a fourth connection end 72. The third connection end 71 is used to connect the door lock panel 101, and the fourth connection end 72 is a free end. The top end of the lower shift block 7 is provided with a second blocking block 73, which abuts against the first blocking block 64 and is closer to the first connection end 61 than the first blocking block 64. The paddles 5 on both sides extend between the upper shift block 6 and the lower shift block 7, and are close to the direction of the second connection end 62. When any paddle 5 moves upward, it can push the second connection end 62 of the upper paddle block 6 upward, so that the protruding shaft 63 drives the lock tongue driving structure 8 upward; when any paddle 5 moves downward, it can push the fourth connection end 72 of the lower paddle 5 downward. At the same time, the second blocking block 73 acts on the first blocking block 64 to push the second connection end 62 upward, which can also enable the protruding shaft 63 to drive the lock tongue driving structure 8 upward.

[0035] In this embodiment, through the coordination of the handle body 1, the rotating member 2 and the transmission assembly, the handle on either side can be pushed and pulled in both directions, and the driving direction of the bolt driving structure 8 is the same, thus ensuring its feasibility.

[0036] like Figure 6 , Figure 8As shown, in order to ensure the automatic reset of the handle body 1, an elastic member 10 is further provided in the above-mentioned installation space, and two elastic members 10 are provided. They are respectively fixed on the upper and lower sides of the rotating end 21 of the rotating member 2, and correspondingly, the mounting base 33 and the mounting top seat 32 are provided with limiting grooves adapted to the elastic member 10 to limit the installation position thereof. The elastic member 10 can be an elastic member such as a spring, a tension spring, etc., which is not specifically limited in this embodiment.

[0037] The bidirectional push-pull handle assembly provided in this embodiment can realize bidirectional pushing and pulling with a single-sided handle, has strong versatility, is more convenient in installation and use, and can be realized only through the cooperation of the rotating part 2 and the transmission assembly. The driving method is simple and has few accessories, which can effectively reduce production costs and has a broader application space.
