[0002] Most of the existing locking mechanisms for sliding doors and windows lock the moving door / window sash with the side of the outer frame or with the adjacent sash frame. However, this locking structure is not suitable for Figure 1 The fan frame structure shown is when there is only one movable sliding door for the user to open, and the locking position of this sliding door does not contact the sides of the outer frame. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to provide a lock structure for a panoramic sliding door, so as to lock the sliding door in a position that does not contact the two sides of the outer frame.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A lock structure for a panoramic sliding door includes a sliding door arranged between a pair of fixed frame leaves, and a limit lock is provided on the side of the sliding door, which is locked with an outer frame using a vertical locking structure. The limit lock is locked and fixed through the bottom and auxiliary limiting is implemented through the top.

[0006] In a preferred embodiment of the present invention, a second lock seat with a circular hole is provided at the bottom of the outer frame, and the limit lock is locked by inserting a second locking pin located at the bottom and having a cylindrical outer diameter that is wide at the top and narrow at the bottom into the circular hole.

[0007] In a preferred embodiment of the present invention, a first lock seat with a waist-shaped hole is provided on the top of the outer frame, and the limit lock is locked by inserting a first lock pin located at the upper portion into the waist-shaped hole.

[0008] In a preferred embodiment of the present invention, screws are further included for connecting the lock body and the first lock pin and the second lock pin respectively, and lock pin connection holes for screwing with the screws are provided at the tails of the first lock pin and the second lock pin.

[0009] In a preferred embodiment of the present invention, the limit lock drives the first lock pin and the second lock pin through the first lock rod and the second lock rod at both ends, and screw holes are provided on the first lock rod and the second lock rod, and the screw rod is connected to the first lock rod or the second lock rod through the screw holes.

[0010] In a preferred embodiment of the present invention, the limit lock drives the first lock pin and the second lock pin through a two-link structure.

[0011] In a preferred embodiment of the present invention, a guide sleeve for guiding the movement of the first lock pin and the second lock pin is further provided on the sliding door.

[0012] The beneficial effects of the present invention are:

[0013] The utility model provides a lock structure for a panoramic sliding door. On the one hand, a round waist hole is used to achieve a secure locking at a predetermined position. On the other hand, a screw structure is used to connect the lock body and the lock pin so that the lock mechanism can be more widely matched with doors and windows of different sizes.

[0018] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

[0019] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments. In all figures, the same reference numerals represent the same elements or elements with the same function.

[0020] Figure 1 A panoramic sliding door with an independent movable leaf structure is shown. This sliding door has a fixed frame leaf 20 within the outer frame 10, with only one movable sliding door 30 for the user to open. The locked position of this sliding door 30 does not contact the sides of the outer frame 10. Therefore, locking is achieved by arranging locks on the sliding door 30 that engage the top and bottom of the outer frame 10.

[0021] Figure 2 and Figure 3 The structure and operation of the lock are shown. The overall locking mechanism is driven by a two-link structure, which locks at both ends. The lock body 410 has a first locking rod 411 and a second locking rod 412 extending from the lock body 410 at the upper and lower ends, capable of retracting and retracting. The first locking rod 411 is connected to the first locking pin 440, while the second locking rod 412 is connected to the second locking pin 450, thereby controlling the insertion and removal of the locking pin. A first lock seat 420 with a waist hole 421 is positioned within the top transverse frame 13 and interacts with the first locking pin 440 to lock the upper portion. A second lock seat 460 with a circular hole 461 is positioned within the bottom transverse frame 12 and interacts with the second locking pin 450 to lock the lower portion. The waisted upper and rounded lower fixing structure allows the lock mechanism to be fixed with the bottom second lock seat 460 as the center of positioning, while the top first lock seat 420 serves as an auxiliary limiting structure. The second locking pin 450 is designed as a cylindrical structure, wide at the top and narrow at the bottom, to fit within the circular hole 461. Guide sleeves 430 are respectively installed on the top and bottom surfaces of the sliding door 30 . Through holes 431 are arranged in the guide sleeves 430 for the first lock pin 440 and the second lock pin 450 to move, which is equivalent to guiding them to retract and extend.

[0022] Furthermore, the first locking rod 411 and the first locking pin 440, and the second locking rod 412 and the second locking pin 450 are connected by a screw 470. A locking pin hole 441 with an internal thread is provided at the bottom of the first locking pin 440 and the top of the second locking pin 450. The screw 470 is connected to the first locking pin 440 or the second locking pin 450 through the locking pin hole 441. This connection structure allows the starting position of the locking pin in the driving locking direction to be changed by rotating the first locking pin 440 or the second locking pin 450, thereby adapting to doors and windows of different sizes.

[0023] In another embodiment, screw holes 413 for connecting to the screw rod 470 are also provided on the first locking rod 441 and the second locking rod 412, so that the connection and fixing positions at both ends of the screw rod 470 can be adjusted, and a longer adjustment stroke can be provided by lengthening the screw rod 470.

[0024] As used in this specification, the singular forms "a," "an," "said," and "the" include the plural forms unless otherwise expressly stated. The terms "include," "comprise," and "contain" as used in this specification indicate the presence of the claimed features, but do not exclude the presence of one or more additional features. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0026] It will be understood that although the terms "first," "second," etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the present invention.
