DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] Reference Figure 1-Figure 10 The utility model provides a trackless sliding window, comprising a window frame 1 and two window sashes 2. Figure 5 and Figure 6 The two window sashes 2 are horizontally slidably arranged in the window frame 1, and the two window sashes 2 can slide to be parallel or side by side with each other. When the two window sashes 2 are parallel, the indoor and outdoor are connected, and air can circulate; when the two window sashes 2 are side by side, the two window sashes 2 block the gap between them and the window frame 1, isolating the indoor and outdoor air flow, and the sealing performance is better than that of traditional sliding windows.

[0035] An embedded lifting handle 3 is hinged on the frame of the window sash 2. The embedded structure can effectively prevent interference between the two window sashes 2. A locking rod 4 is also slidably arranged on the frame of the window sash 2. Sliding the locking rod 4 can lock or separate it from the outer side of the window frame 1. The top of the lifting handle 3 abuts against the locking rod 4. Pulling the lifting handle 3 can drive the locking rod 4 to slide on the frame of the window sash 2.

[0036] See Figure 7 and Figure 8 A return spring 5 is also connected between the lock rod 4 and the frame of the window sash 2. A connecting protrusion 401 is arranged on the lock rod 4. A transmission protrusion 301 is arranged on the top of the lifting handle 3. The transmission protrusion 301 is pressed against the connecting protrusion 401. Pulling the lifting handle 3 can make the transmission protrusion 301 press the connecting protrusion 401, and drive the lock rod 4 to move downward and separate from the outer side of the window frame 1. Because when the two window sashes 2 are parallel, the two window sashes 2 can rely on each other to provide support to prevent swinging back and forth, but when the two window sashes 2 are side by side, the width set for the parallel superposition of the two window sashes 2 becomes a disadvantage, so that the two window sashes 2 are easy to swing back and forth under the action of outdoor wind. For this reason, the lock rod 4 set can lock the two window sashes 2 in the parallel state to the outer side of the window frame 1, thereby improving the stability of the window sashes 2.

[0037] See Figure 4 The inner side of the window sash 2 is provided with a slider 201, and the outer side of the window sash 2 is provided with a slide groove 202. When the two window sashes 2 slide to a parallel state, the slider 201 can be inserted into the slide groove 202 and slidably connected therewith, thereby improving the stability of the two window sashes 2 when sliding in parallel. The bottom of the window sash 2 is provided with a self-lubricating block 6, which plays a lubricating role, reduces friction, and improves the smoothness of sliding.

[0038] See Figure 3 A top pressure spring 7 is provided at the top of the window sash 2 to provide a pre-tightening support force for the top of the window sash 2 so that the window sash 2 can be more stably fixed in the window frame 1.

[0039] See Fig. 9 and Fig.10 A locking member 8 is provided on the upper frame of the window frame 1. When the two window sashes 2 slide to a parallel state, the inner side surface of the inner window sash 2 abuts against the locking member 8. The locking member 8 and the window frame 1 together form a clamping mechanism to limit the forward and backward movement range of the two window sashes 2 and facilitate the removal and replacement of the window sashes 2. The locking member 8 is slidably provided on the window frame 1. A pressing lock 9 is provided on the locking member 8 to lock with the window frame 1. Pressing the pressing lock 9 can release the lock, so that the locking member 8 can be removed from the window frame 1.

[0040] The outer side of the window frame 1 is provided with a side groove 101, and a screen 10 is slidably provided in the side groove 101. The screen 10 does not need to occupy a separate track, saving space. Its screen can be made of corundum for better performance. A wool strip notch is provided on the inner side of the screen 10 so as to fit closely with the window sash 2 and the window frame 1, which can effectively prevent mosquitoes from entering. Drain holes 11 are provided at the bottom of the side groove 101 and the bottom of the window frame 1, so that rainwater entering the window frame 1 is directly discharged to the outside from the drainage hole 11 to avoid water accumulation. At the same time, the dust accumulated in the window can be swept away through the drainage hole 11, which is convenient for cleaning and maintenance.

[0041] Since the width of the track of the screen window 10 is reduced, without increasing the width of the window frame 1, two folding curtains 12 are arranged on the inner side of the window frame 1. The two folding curtains 12 are symmetrically hidden in the left and right frames of the window frame 1. The two sides are respectively used to set curtains with different shading degrees, which eliminates the process of drilling holes in the wall to install sliding rods and curtains, and saves more indoor space than traditional curtains.

[0042] Working principle:

[0043] When the window sash 2 needs to be opened for ventilation, first pull up the lifting handle 3 on one window sash 2, so that the locking rod 4 on the window sash 2 moves downward and separates from the outside of the window frame 1, then pull the lifting handle 3 toward the indoor direction, drive the window sash 2 to slide toward the indoor direction until it is parallel to the other window sash 2, then slide the window sash 2 left and right, so that the two window sashes 2 are stacked together in parallel, and the window sash 2 is now fully opened. When the window sash 2 needs to be closed, the reverse operation slides one of the window sashes 2 to a parallel position, and the two window sashes 2 are completely sealed with the window frame 1 to block the circulation of air inside and outside. When a new window sash 2 or screen 10 needs to be replaced, press the lock 9 to release the lock, and then the locking member 8 can be removed from the window frame 1. Without the clamping effect of the locking member 8, it is easier to remove and replace the window sash 2 or screen 10.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
