[0019] As shown in the accompanying drawings, the utility model is a side-mounted lock for sliding doors and windows, comprising an outer frame and a movable fan, wherein the movable fan is located on one side of the middle part of the frame and is provided with a center column profile 10. It should be understood that the movable fans of existing sliding doors or sliding windows all include four profiles, namely, two horizontally arranged horizontal profiles above and below, and vertical profiles arranged vertically on the left and right. The center column profile 10 is the vertical profile located in the middle part of the outer frame in the closed state. For the convenience of explanation, it is therefore called the center column profile 10, comprising a lock shell 1 installed in the center column profile 10, a lock tongue 2 that is telescopically mounted on the front side of the center column profile 10, a switch dial 3 that is slidably mounted on the side of the center column profile 10, and a lock seat 6 for the lock tongue 2 to be plugged in, that is, the lock seat 6 is detachably connected to the lock tongue 2, and the lock tongue 2 is installed inside the lock shell 1, and one end protrudes from the lock shell 1, as shown in FIG. Figure 3 The thickness direction of the lock case 1 is parallel to the width direction of the center column profile 10, and the length direction of the lock case 1 is parallel to the thickness direction of the center column profile 10. The front side of the center column profile 10 is provided with an opening, and the lock case 1 is placed in the center column profile 10 through the opening, and the front end of the lock case 1 is provided with a connecting hole, which is screwed through the connecting hole and fixedly connected to the center column profile 10. The lock tongue 2 is arranged in the lock case 1 and is kept in a state of protruding from the opening. The switch member 3 is linked to the lock through the square shaft 4. Tongue 2, thereby driving the lock tongue 2 to retract into the lock shell 1, a slot is provided on the lock tongue 2, and the square shaft 4 is inserted into the slot. The lock shell 1 is provided with a strip groove at a position corresponding to the square shaft 4 for installation and sliding of the square shaft 4. The other end of the square shaft 4 is plugged into the switch dial 3. By pulling the switch dial 3 backward, the lock tongue 2 is retracted backward into the lock shell 1. The lock seat 6 is installed on the sliding door and window and corresponds to the position of the lock tongue 2, which is convenient for connection with the lock tongue 2. The lock seat 6 has a groove for the lock tongue 2 to extend into.

[0020] The utility model relates to a side-mounted lock for sliding doors and windows. The structure of the side-mounted lock body can reduce the size of the width of the profile it occupies. The lock body structure is placed into the profile from the opening on the front side of the center column profile 10, and the lock tongue 2 is kept extending forward from the center column profile 10. That is, the movement direction of the lock tongue 2 is to slide and retract in the center column profile 10 forward and backward, thereby greatly eliminating the structure in which the lock body occupies the width direction of the center column profile 10. Figure 3 , so that when the lock body is installed in the middle column profile 10, its thickness corresponds to the width dimension of the middle column profile 10, and its length corresponds to the thickness dimension of the middle column profile 10. The thickness of the lock shell 1 is less than 1.2 cm, so it is more suitable for extremely narrow doors and windows. The switch dial 3 of the lock body is installed on the side of the middle column profile 10, thereby maintaining the simplicity of the surface of the movable fan and improving the overall aesthetics of the sliding doors and windows. Moreover, the side-mounted lock body structure is installed on the middle column profile of the movable fan, and is not installed on the vertical profile on the side of the outer frame, so that the other vertical profile can be hidden in the outer frame, further simplifying the front of the sliding doors and windows, making the sliding doors and windows more simple and beautiful.

[0021] In this embodiment, the front end of the lock housing 1 is provided with an opening for the lock tongue 2 to enter and exit. One end of the lock tongue 2 protrudes from the lock housing 1 through the opening, and the end protrudes outside the center column profile 10 and is detachably connected to the lock seat 6. An elastic member 201 is provided inside the lock housing 1 and is connected to the lock tongue 2 through the elastic member 201. Figure 5 The lock tongue 2 shown is arranged in the lock housing 1, and one end protrudes from the front end of the lock housing 1 through the opening and protrudes to the outside of the center column profile 10. The lock tongue 2 is kept in the extended state by the elastic member 201 provided, and the elastic member 201 can also help the lock tongue 2 to reset. After pulling the switch dial 3 to retract the lock tongue 2, the switch dial 3 is released, and the lock tongue 2 returns to the extended state under the restoring force of the elastic member 201.

[0022] In this embodiment, the end of the lock tongue 2 protruding from the opening is provided with an inclined surface 20, and the inclined surface 20 is provided on the closing side. Figure 6 , Figure 6 This is the main view of a general sliding door and window. When the movable sash is pulled to the left to close, the inclined surface 20 is set on the left side of the lock tongue 2, and automatic locking is achieved through the inclined surface 20. When people slide the movable sash to the left, the inclined surface 20 of the lock tongue 2 is against the lock seat 6. Due to the limitation of the movable sash, when the lock tongue 2 is against the lock seat 6, the lock tongue 2 will automatically slide along the inclined surface 20 and retract into the lock shell 1 until the lock tongue 2 is aligned with the groove of the lock seat 6. The lock tongue 2 is then ejected back into the lock seat 6 by the elastic member 201, achieving automatic locking.

[0023] In this embodiment, the switch member 3 is slidably connected to the sliding seat 5, and the sliding seat 5 is fixedly installed on the side of the center column profile 10. Figure 2 Or 4, the sliding seat 5 is provided with a connecting hole for fixedly connecting the side of the center column profile 10, and the switch dial 3 is provided with a slide groove. The sliding seat 5 is arranged in the slide groove and slides linearly along the telescopic direction of the lock tongue 2. The switch dial 3 then clamps the sliding seat 5 through the connecting member, so that the sliding seat 5 cannot be separated from the switch dial 3 and can only slide linearly. The connecting member can directly adopt a retaining spring, which is used to snap onto the bottom of the protruding block of the switch dial 3 for plugging the square shaft 4. The switch dial 3 is installed on the side of the center column profile 10 through the sliding seat 5, avoiding the front facing people and maintaining the integrity of the front of the profile.

[0024] In this embodiment, the lock seat 6 is installed on another movable fan and corresponds to the lock tongue 2. The lock body structure can be applied to sliding doors or windows with double movable fans. The middle column profile 10 of one movable fan is installed with a lock shell 1 part, and the lock shell 1 is installed on the front side of the middle column profile 10. The middle column profile 10 of the other movable fan is installed with a lock seat 6 part, and the lock seat 6 is installed on the rear side of the middle column profile 10 and corresponds to the lock tongue 2. When the movable fan is closed, the lock tongue 2 on one movable fan is plugged into the lock seat 6 of the other movable fan. By pulling the switch dial 3, the lock tongue 2 is disengaged from the lock seat 6 and retracted backward into the lock shell 1, and then the movable fan is opened. It can also be applied to sliding doors and windows with multiple movable fans by respectively installing the lock shell 1 and the lock seat 6 on the middle column profiles 10 of the two adjacent movable fans.

[0025] In this embodiment, the lock seat 6 is installed on the fixed profile and corresponds to the lock tongue 2. The lock body structure can be applied to sliding doors and windows with one fixed and one movable. If a fixed and one movable sliding door and window is used, the lock seat 6 is installed on the rear side of the middle column profile 10 of the fixed fan, and the installation position of the lock shell 1 remains unchanged. There are also sliding windows that will have a middle stile profile in the middle of the outer frame to cooperate with the movable fan to seal, such as system sliding windows, curtain wall windows, etc. At this time, the lock seat 6 can be installed to the middle stile profile of the outer frame and correspond to the position of the lock tongue 2.

[0026] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
