Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0026] As shown in the attached Figures 1-7 figure, the structure of a new - type overhead lock includes a lock base and a lock core arranged on the lock base. The lock core is slidably arranged up and down on the lock base. The upward or downward sliding movement of the lock core forms a locking and unlocking structure. The lock core includes a slide block, a slide seat, a rod seat and a lock rod arranged on the rod seat. One side of the lock base is provided with a slide cavity, and the other side is provided with a lock hole. The slide seat is arranged in the slide cavity, and the slide block is arranged on the lock base on the side of the lock hole. After the slide seat is arranged in the slide cavity, the slide seat can form an upward or downward limited - sliding structure in the slide cavity. The slide block, the slide seat and the rod seat are connected and installed to form a synchronous linkage structure. By the upward or downward sliding of the slide block, the slide seat and the rod seat are driven to move synchronously. The lock rod on the rod seat will also move synchronously with the rod seat, thus forming a locking and unlocking structure. The slide block is provided with a lock cavity, and the lock cavity is eccentrically swingably provided with an on - off key, and the on - off key and the lock hole of the lock base can form a locking structure. The locking structure of the lock core on the lock base is formed by the locking state between the on - off key and the lock hole. The unlocking structure is formed after the locking state between the on - off key and the lock hole is released and the lock core slides downward on the lock base.
[0027] In the present utility model, a pin base is further included. The pin base is provided with a swing cavity. The upper end of the power switch key is provided with a button, and the lower end of the power switch key is provided with a swing arm. The swing cavity and the swing arm are eccentrically provided with shaft holes. The swing arm and the swing cavity are installed by a pin shaft through the shaft holes, and the swing arm is installed in the swing cavity, forming an installation structure in which the power switch key can swing eccentrically on the pin base. The pin base is installed in the locking cavity of the slider. By arranging the shaft hole in the upper left corner of the swing arm to form an eccentric shaft hole, the button is located in the upper right corner of the swing arm, and the weight of the button makes the eccentric swing of the power switch key more stable.
[0028] In the present utility model, the rod base, the slide base and the pin base are provided with synchronous holes. The rod base, the slide base and the pin base are connected and installed by a screw through the synchronous holes, and the rod base, the slide base and the pin base form a connection structure that slides synchronously upward or downward. Since the pin base is installed in the locking cavity of the slider, a synchronous linkage structure among the slider, the slide base and the rod base is formed.
[0029] In the present utility model, the slide base is provided with a connection hole, the pin base is provided with a connection arm and the connection arm is provided with a connection hole, and the slider is provided with an arm groove and the arm groove is provided with a connection hole. The connection arm is installed in the arm groove, and the slide base, the pin base and the slider are connected and installed by screws through the connection holes, forming a synchronous linkage structure among the slide base, the pin base and the slider.
[0030] In the present utility model, a handle base is further included. The handle base can also be understood as a handle located on the other side of the door body. The upper and lower parts of the handle base and the lock base are provided with installation holes. The rod base is provided with a sliding hole, and the sliding hole is used to provide a moving space for the rod base when it slides upward or downward. The upper parts of the lock base and the handle base are connected and installed by screws, and the screws pass through the sliding hole of the rod base. The lower parts of the lock base and the handle base are connected and installed by screws.
[0031] In the present utility model, the swing arm is provided with a clamping part. The swing arm makes the clamping part form a clamping structure with the bottom of the lock hole through eccentric swing. When the slider is pushed upward, the clamping part of the swing arm slides to the lock hole. When the clamping part no longer receives the top force from the contact surface with the lock base, the swing arm makes an eccentric swing, the button swings outward to the lock hole, and the clamping part swings into the lock hole to form a clamping structure with the bottom of the lock hole. The lock core is in a clamped state on the lock base, and the lock core cannot slide downward, thus forming a locked state.
[0032] In the present utility model, the slide base is provided with a bayonet. A silent block is installed on the slide base through the bayonet. The bottom of the silent block can form an installation on the slide base by setting a shape that mutually engages with the bayonet. The silent block can be made of a rubber block, and the sound insulation effect is better. When the slide base slides upward or downward in the sliding cavity, impacts are generated between the silent block and the top and bottom of the sliding cavity, achieving a better sound insulation effect.
[0033] In the present utility model, a positioning sleeve is provided on the upper part of the lock rod. The lock rod can be inserted into the positioning sleeve in an up-and-down movable manner. Since the lock rod needs to be inserted into the corresponding bolt hole in the upper door frame to form a locking structure, the lock rod has a certain length. The positioning sleeve on the upper part of the lock rod can enhance the stability of the lock rod during the upward movement, avoiding the long-term swinging of the lock rod, which may lead to inaccurate insertion into the bolt hole of the upper door frame.
[0034] Principle of use:
[0035] The following principle of use is described by taking the PT door as an example. It should be noted that a bolt hole corresponding to the lock rod to form a locking structure is provided at the closed part of the door body on the upper door frame. The upper door frame is also a track for the door body to slide. A corresponding cavity structure is provided inside the door body frame of the profile door and window. The rod seat, lock rod and positioning sleeve are all installed in the cavity structure of the door body frame. Installation openings corresponding to the lock seat and lock core need to be provided on the door body frame. The two lock seats clamp the door body frame and are installed through the installation openings. The door and window structure is very easy to understand and can also be understood by referring to the attached Figure 7 and there is no need for a detailed structural description.
[0036] When locking is required, push the lock slider upward. The clamping part of the swing arm slides to the lock hole. The clamping part no longer receives the top force from the contact surface with the lock seat, and the swing arm undergoes an eccentric swing. The key swings outward from the lock hole, and the clamping part swings into the lock hole and forms a locking structure with the bottom of the lock hole. Then the slider cannot slide downward, and the lock core is in a locked state on the lock seat. At this time, the lock rod on the rod seat is inserted into the bolt hole of the upper door frame, thus forming a locked state.
[0037] When unlocking is required, only press the upper part of the key of the unlocking key. The key rotates inward from the lock hole, and the clamping part of the swing arm will rotate outward from the lock hole. When the clamping part rotates out of the lock hole, the clamping part and the bottom of the lock hole no longer form a locking structure. The lock core slides down automatically due to its own weight. At this time, the lock rod disengages from the bolt hole of the upper door frame to form an unlocked state.
[0038] The structure of the sky lock of the present utility model is more convenient during use. Pushing the slider upward can achieve the locked state, and gently pressing the unlocking key can achieve the unlocked state. Only the lock seat and the slider are located outside the door body frame, and other structures are hidden in the cavity structure of the door body frame, which is more concealed and beautiful.
[0039] The above embodiments are the preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made shall fall within the protection scope of the present utility model.
