DETAILED DESCRIPTION

[0023] 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.

[0024] As shown in the accompanying drawings, the utility model is a side-mounted handle with a child lock, comprising a housing 1, a sliding member 6, and a first face gear 2 and a second face gear 3 meshing with each other. The shapes and distribution of the first face gear 2 and the second face gear 3 are as shown in FIG. Figure 3 As shown, they are arranged perpendicular to each other, the first face gear 2 is rotatably arranged on the front side of the shell 1, and is connected to a handle 4 arranged on the front side of the shell 1, the second face gear 3 is rotatably arranged on a side surface of the shell 1, and is connected to a transmission shaft 5 arranged on a side surface of the shell 1, the handle 4 is arranged on the front side of the shell 1, the transmission shaft 5 is arranged on the left side or the right side of the shell 1, and is installed on the side of the window sash profile facing the glass through the side surface to achieve side installation, the sliding member 6 is arranged on the front side of the shell 1 according to the radial sliding of the first face gear 2, and is connected to the first face gear 2 through the sliding of the sliding member 6, so that the first face gear 2 cannot rotate, and a sliding groove mouth slidably connected to the sliding member 6 is provided on the front side of the shell 1, the sliding member 6 is arranged in the shell 1, and protrudes to the outside through the sliding groove mouth, so that people can push the sliding member 6 to achieve anti-locking or unlocking.

[0025] The utility model discloses a side-mounted handle with a child lock. A first face gear 2 and a second face gear 3 are provided to cooperate with each other. The handle 4 utilizes the meshing of the first face gear 2 and the second face gear 3 to transmit the transmission direction of the handle 4 on the front face of a shell body 1 to a transmission shaft 5 on the side face of the shell body 1, so that the shell body 1 can be side-mounted to one side of a window sash profile. The window sash profile does not need to reserve too much width, thereby reducing the width of the window sash profile to achieve an extremely narrow effect. Since the handle is side-mounted on the side face of the window sash profile facing the glass, that is, the front face 19 of the window sash profile has no other structural obstruction, the window sash side profile can also be hidden in the window frame. In addition, a child safety lock structure is added. By pushing the sliding member 6 to engage in the first face gear 2, the first face gear 2 is restricted from rotating, thereby preventing children from accidentally touching the handle 4 to open the window sash, thereby improving safety performance.

[0026] like Figure 7-8 As shown, the first face gear 2 and the second face gear 3 are both provided with a disc segment 20, and one end surface of the disc segment 20 has a plurality of convex teeth 21 distributed in a central ring shape, and an engaging recess 22 is formed between two adjacent convex teeth 21 on the same disc segment 20, and the convex teeth 21 on the second face gear 3 match the engaging recess 22 on the first face gear 2.

[0027] In this embodiment, one end of the sliding member 6 is provided with a clamping portion 601 matching the meshing recess 22, and the other end is provided with a push button 602 slidably connected to the shell 1, that is, the clamping portion 601 can be understood as a single convex tooth 21 matching the meshing recess 22. By sliding the sliding member 6 to one end close to the first face gear 2, the clamping portion 601 enters one of the meshing recesses 22, thereby clamping the first face gear 2 so that it cannot rotate. Since the first face gear 2 is fixedly connected to the handle 4, the handle 4 cannot rotate either, that is, the clamping portion 601 can lock the position of the handle 4 to prevent the handle 4 from falling and tilting.

[0028] In this embodiment, the handle 4 is provided with a spring 102 and a positioning bead 101 on the side facing the housing 1. Figure 1 The front side of the housing 1 is provided with a through hole corresponding to the positioning bead 101, the side of the handle 4 facing the housing is provided with a connecting column 44, the side of the first face gear 2 away from the convex tooth 21 is provided with a plum blossom groove 200, specifically, the disc segment 20 of the first face gear 2 protrudes with a connecting portion 201, and the connecting portion 201 extends to the outside of the housing 1, the plum blossom groove 200 is provided on the connecting portion 201, the connecting column 44 is plugged into the plum blossom groove 200, and is fixedly connected by screws, the handle 4 is protrudingly provided with a connecting column 44 in the middle of the surface, that is, the rotation center, the cross-section of the connecting column 44 is plum blossom-shaped, and a plurality of positioning grooves are annularly distributed outside the connecting column 44, the The spring 102 and the positioning bead 101 are both arranged in the groove, and the positioning is achieved by the positioning bead 101 abutting against the through hole on the shell. The handle 4 is coaxially arranged with the first face gear 2, and a hexagram groove 200 is provided on the side of the first face gear 2 connected to the handle 4. The connecting column 44 is inserted into the hexagram groove 200. The connecting column 44 of the handle 4 is provided with a threaded groove for connecting screws. The screws are passed through the first face gear 2 and threadedly connected to the handle 4 to achieve a fixed connection between the handle 4 and the first face gear 2. The positioning bead 101 and the spring 102 are mainly coordinated with the through hole, so that the handle 4 drives the first face gear 2 to rotate a certain angle and the positioning bead can abut against the corresponding through hole every time, thereby achieving the positioning effect.

[0029] In this embodiment, a cylindrical section 301 and a boss 302 rotatably connected to the shell 1 are respectively arranged in the middle of the two end surfaces of the disc segment 20 located on the second face gear 3, and the convex teeth 21 are annularly distributed on the outer curved surface of the cylindrical section 301. The arrangement of the cylindrical section 301 and the boss 302 allows both ends of the second face gear 3 to be rotatably connected to the shell 1. The shell 1 is provided with connecting holes at the connection between the cylindrical section 301 and the boss 302, so that its rotation is smoother; wherein another boss 302 is provided on one end surface of the disc segment 20 located on the first face gear 2 away from the convex teeth 21, and the boss 302 protrudes from the front of the shell 1 and is fixedly connected to the handle 4.

[0030] In this embodiment, a square groove 303 is provided in the middle of the boss 302, one end of the transmission shaft 5 is inserted into the square groove 303, and the other end protrudes out of the shell 1 and is connected to the transmission box 11. The transmission box 11 is an existing structure. A gear connected to the transmission shaft 5 is provided in the transmission box 11, and a transmission bar is connected to one side of the gear, and a rack is provided on one side of the transmission bar.

[0031] When the window sash is unlocked, the handle 4 is turned to the closed position. The second face gear 2 rotates, thereby driving the second face gear 3 to rotate at the same time. The transmission shaft 5 on the second face gear 3 rotates and drives the transmission bar of the transmission box 11 to move upward. At this time, the window sash is unlocked and the handle 4 is turned to the closed position again. The second face gear 3 rotates driven by the first face gear 2, and then the transmission bar of the transmission box 11 is driven downward through the transmission shaft 5. The sliding member 6 is pushed to engage with the first face gear 2. Since the sliding member 6 cannot move horizontally, it can only move forward and backward along the radial direction of the first face gear 2. Therefore, after the engaging portion 601 is engaged with the meshing recess 22 of the first face gear 2, the first face gear 2 cannot continue to rotate.

[0032] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
