Technical Field
[0001] This utility model relates to the field of sliding window technology, and in particular to a quick-installation sliding window locking device. Background Technology
[0002] A sliding window is a type of window that opens and closes by sliding horizontally. When open, the window sash remains parallel to the wall, does not occupy indoor space, maintains the integrity of the view outside the window, and allows for flexible ventilation from all sides.
[0003] Sliding windows require locking devices to control the opening size, ensuring that the window is not accidentally pushed open further after being opened, thus improving safety. Currently, locking devices are usually integrated inside the sliding window, making maintenance inconvenient. For sliding windows without built-in locking devices, there are also locking devices that can be installed on the outside of the window, but they are usually fixed by adhesive or screws, which is not only inconvenient to install and remove, but also easy to damage the window.
[0004] Therefore, to address the above issues, a quick-install sliding window locking device can be designed. It can be quickly installed on the outside of sliding windows of various sizes to control the opening and closing size of the sliding window. It is also easy to disassemble and can be quickly disassembled for storage when not in use. Utility Model Content
[0005] To overcome the problem that current locking devices are usually integrated inside the casement window, making maintenance inconvenient, there are also locking devices that can be installed on the outside of the window for casement windows without built-in locking devices. However, these are usually fixed by adhesive or screws, which is not only inconvenient to install and remove, but also easy to damage the window.
[0006] The technical solution of this utility model is as follows: a quick-install sliding window locking device, including a fixed window frame, an opening window frame, a first suction cup, a second suction cup, and a chain. A miniature air pump is fixedly installed inside both the first and second suction cups. A power supply interface is provided at one end of the miniature air pump.

The first suction cup is located on one side of the fixed window frame, and the second suction cup is located on one side of the opening window frame.
[0007] Preferably, by setting a power supply interface, a miniature air pump can be powered through a common connecting cable. The miniature air pump can then perform air extraction on the first and second suction cups, allowing the first and second suction cups to be easily and quickly fixed to one side of the fixed window frame and the sash window frame, respectively. By setting a chain to connect the first and second suction cups, the opening and closing size of the sash window frame can be locked and controlled.
[0008] Preferably, both the first and second suction cups are equipped with control panels, and indicator lights are provided on one side of the control panels.
[0009] Preferably, multiple sets of sliding hinges are fixedly installed between the fixed window frame and the sash window frame.
[0010] Preferably, two sets of handles are provided on one side of the sash window frame, and two sets of window locks are provided on each side of the sash window frame.
[0011] Preferably, a mounting ring is fixedly installed on one side of the first suction cup, and a spring buckle is connected inside the mounting ring, which is connected to the chain.
[0012] Preferably, a sleeve is fixedly installed on one side of the second suction cup, and a connector is slidably connected inside the sleeve. The connector is fixedly connected to one end of the chain, and a buffer spring is fixedly installed between the connector and the second suction cup.
[0013] Preferably, a hook is fixedly installed at the other end of the chain.
[0014] The beneficial effects of this utility model are:
[0015] When installing the entire device, first attach the first and second suction cups to one side of the fixed window frame and the sash window frame, respectively. Power the miniature air pump via a common TPCY-C cable through the power supply interface. Control the miniature air pump through the control panel. The miniature air pump evacuates the first and second suction cups, allowing for easy and quick fixation of the first and second suction cups to one side of the fixed window frame and the sash window frame, respectively. Then, according to actual usage needs, hook the spring clip into the appropriate position on the chain to connect and fix the first suction cup to the chain. The second suction cup can be connected to the chain using a sleeve and connector. This allows for control of the opening and closing size of the sash window frame.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a quick-installation sliding window locking device, comprising a fixed window frame 1, an opening window frame 2, a first suction cup 4, a second suction cup 5, and a chain 6. A miniature air pump 701 is fixedly installed inside both the first suction cup 4 and the second suction cup 5. One end of the miniature air pump 701 is provided with a power supply interface 702, which uses a common TPCY-C interface. The chain 6 is located between the first suction cup 4 and the second suction cup 5. The first suction cup 4 is located on one side of the fixed window frame 1, and the second suction cup 5 is located on one side of the opening window frame 2. By providing power through the power supply interface 702, the miniature air pump 701 can be powered via a common connecting cable. The miniature air pump 701 then pumps air from the first suction cup 4 and the second suction cup 5, allowing for quick and easy fixing of the first suction cup 4 and the second suction cup 5 to one side of the fixed window frame 1 and the opening window frame 2, respectively. The chain 6 connects the first suction cup 4 and the second suction cup 5, thereby locking and controlling the opening size of the opening window frame 2.
[0023] Please see Figure 1 and Figure 3In this embodiment, a control panel 703 is provided around the first suction cup 4 and the second suction cup 5, and an indicator light 704 is provided on one side of the control panel 703. The micro air pump 701 can be operated by the control panel 703, and the power supply status of the micro air pump 701 can be easily observed by the indicator light 704. Multiple sets of sliding hinges 3 are fixedly installed between the fixed window frame 1 and the opening window frame 2. The sliding hinges 3 connect and fix the fixed window frame 1 and the opening window frame 2, so that the opening window frame 2 can be opened and closed freely. Two sets of handles 201 are provided on one side of the opening window frame 2, and two sets of window locks 202 are provided on both sides of the opening window frame 2. The handles 201 can be used to easily push the opening window frame 2 to open and close, and the window locks 202 can lock the opening window frame 2 when it is closed.
[0024] Please see Figure 2 and Figure 4 In this embodiment, an mounting ring 401 is fixedly installed on one side of the first suction cup 4. A spring buckle 402 is connected inside the mounting ring 401, and the spring buckle 402 is connected to the chain 6. The spring buckle 402 is installed by setting the mounting ring 401, and the spring buckle 402 can be easily connected to the chain 6, thereby connecting the first suction cup 4 and the chain 6. A sleeve 501 is fixedly installed on one side of the second suction cup 5. A connector 503 is slidably connected inside the sleeve 501, and the connector 503 is fixedly connected to one end of the chain 6. A buffer spring 502 is fixedly installed between the connector 503 and the second suction cup 5. The second suction cup 5 and the chain 6 can be connected by setting the sleeve 501 in conjunction with the connector 503. The buffer spring 502 can provide a certain buffer when the window frame 2 is opened, and protect the window frame 2 and the chain 6. A hook 601 is fixedly installed at the other end of the chain 6. When the redundant length of the chain 6 is too long, one end of the chain 6 can be hung on the mounting ring 401 to prevent the chain 6 from affecting the glass of the sliding window.
[0025] When in operation, the micro air pump 701 can be powered by the power supply interface 702 through a common connecting cable. The power supply status of the micro air pump 701 can be easily observed by the indicator light 704. First, attach the first suction cup 4 and the second suction cup 5 to one side of the fixed window frame 1 and the opening window frame 2 respectively. Control the micro air pump 701 using the control panel 703. Use the micro air pump 701 to perform air extraction operation on the first suction cup 4 and the second suction cup 5. The first suction cup 4 and the second suction cup 5 can be quickly and easily fixed to one side of the fixed window frame 1 and the opening window frame 2 respectively. Then, according to the actual use requirements, hang the spring buckle 402 at the appropriate position of the chain 6 to connect and fix the first suction cup 4 to the chain 6. The second suction cup 5 can be connected to the chain 6 using the sleeve 501 and the connector 503. The buffer spring 502 can provide a certain buffer when the opening window frame 2 is opened, and provide protection for the opening window frame 2 and the chain 6. Thus, the opening size of the opening window frame 2 can be controlled and locked.
[0026] When the opening size of the controllable window frame 2 is small, the redundant length of the chain 6 will be too long. The hook 601 can be used to hang one end of the chain 6 on the mounting ring 401 to prevent the redundant chain 6 at one end from affecting the glass of the sliding window.
[0027] Through the above steps, the micro air pump 701 can be powered via the power supply interface 702 using a common connecting cable. The micro air pump 701 then pumps air from the first suction cup 4 and the second suction cup 5, allowing for easy and quick fixation of the first suction cup 4 and the second suction cup 5 to one side of the fixed window frame 1 and the opening window frame 2, respectively. The first suction cup 4 and the second suction cup 5 are connected by the chain 6, thereby locking and controlling the opening size of the opening window frame 2. This method is convenient to install and remove, reusable, and its vacuum suction installation on the outside of the window prevents damage. This addresses the current problem that locking devices are typically integrated inside sliding windows, making maintenance inconvenient. While there are locking devices that can be installed on the outside of sliding windows without built-in locking mechanisms, these are usually fixed with adhesive or screws, which are not only inconvenient to install and remove but also prone to damaging the window.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
