[0032] Embodiment 1:

[0033] like Figures 1 to 8 As shown, a lock-type corner guard of a screen window comprises a first corner guard body 1 and a second corner guard body 2, and a sliding lock 3 connecting the first corner guard body 1 and the second corner guard body 2; the first corner guard body 1 and the second corner guard body 2 are respectively provided with a pair of clamping arms, and the clamping arms are used to clamp the screen window; the first corner guard body 1 is provided with a first locking hole 4 at the corner part, the sliding lock 3 is provided at the front of the corner part of the first corner guard body 1, and the sliding lock 3 is provided with a second locking hole 5 matched with the first locking hole 4; the second corner guard body 2 is provided with a connecting column 6 at the corner part, and a plurality of locking tongues 7 are provided at the outer periphery of the end of the connecting column 6; the locking tongue 7 passes through the first locking hole 4 and the second locking hole 5, and is locked by the second locking hole 5 under the sliding operation of the sliding lock 3.

[0034] The locking type window screen corner guard improves the connection method and locking structure of the first corner guard body 1 and the second corner guard body 2, so that it can be connected to the window screen to protect the window screen and is also easy to install and disassemble; and the corner guard is composed of only three parts without any small parts, so it is relatively simple to manufacture and use.

[0035] The first corner guard body 1 and the second corner guard body 2 can clamp the column window screen using their clamping arms, and the corner portion in the middle can be used to install and connect the sliding lock buckle 3; the connecting column 6 set on the second corner guard body 2 and the locking tongue 7 set thereon can be used to connect the sliding lock buckle 3 to connect the two corner guard bodies together.

[0036] The locking tongue 7, the connecting column 6 and the second corner protector body 2 are integrally formed structures, and the three do not move relative to each other. The connecting column 6 is used to allow the locking tongue 7 to pass through the first locking hole 4 and the second locking hole 5. Under the sliding operation of the sliding lock buckle 3, the second locking hole 5 forms a limit for the locking tongue 7 to complete the locking operation. With this structural setting, the existing locking and unlocking operations can be completed by sliding the sliding lock buckle 3 back and forth. The sliding lock buckle 3 is set on the front side of the corner protector, which is also convenient to use and operate.

[0037] Preferably, the locking tongues 7 are a pair symmetrically arranged at the periphery of the end of the connecting column 6, and the width of the locking tongues 7 is smaller than the diameter of the connecting column 6. That is, a pair of flange structures are formed at the end of the connecting column.

[0038] The shape of the first lock hole 4 is similar to the shape formed by the end surface of the connecting column 6 and the pair of locking tongues 7, and the size is slightly larger than the shape, so that the connecting column 6 and the pair of locking tongues 7 can pass through. Preferably, the connecting column 6 is arranged on the angle bisector of the corner guard, and the pair of locking tongues 7 are symmetrically arranged on both sides of the angle bisector, and the connecting line of the pair of locking tongues 7 is perpendicular to the angle bisector, so that the limited space structure of the corner part can be fully utilized, and the sliding lock buckle 3 only needs to slide back and forth in the direction of the angle bisector.

[0039] In some embodiments, the size of a pair of locking tongues 7 may be greater than or equal to the end surface size of the connecting column 6; the locking tongues 7 may also be arranged in other orientations, and the corresponding sliding directions of the sliding locks are also different.

[0040] Furthermore, the second lock hole 5 includes a lock hole insertion position 501, and a lock hole locking position 502 located on one side of the lock hole insertion position 501, the size of the lock hole locking position 502 is slightly larger than the outer circumferential size of the connecting column 6, the lock hole locking position 502 is connected to the lock hole insertion position 501 and the diameter is smaller than the length of the lock hole insertion position 501.

[0041] The lock hole insertion position 501 is comparable to the first lock hole 4 in shape and size. When connected, the lock hole insertion position 501 corresponds to the first lock hole 4. When the connecting column 6 and the locking tongue 7 pass through the first lock hole 4 and the lock hole insertion position 501, when the sliding lock buckle 3 is slid, the lock hole insertion position 501 can be misaligned with the first lock hole 4, that is, the lock hole locking position 502 corresponds to the first lock hole 4. Since the size of the lock hole locking position 502 is smaller than the size of the first lock hole 4, a pair of locking tongues 7 are limited and cannot fall out of the first lock hole 4, thereby completing the locking.

[0042] Furthermore, the sliding lock buckle 3 is a hollow structure for accommodating the end of the connecting column 6 and the locking tongue 7 inserted from the second locking hole 5 .

[0043] Preferably, both side edges of the sliding lock buckle 3 are provided with arc grooves 13 connected to the hollow structure therein. Under this structure, the sliding lock buckle 3 is similar to a double-layer structure, in which the front layer and the quilt layer are connected together by an arc wall, the second lock hole is provided on the quilt layer, and the front layer is used to move the entire sliding lock buckle.

[0044] Furthermore, sliding feet 9 are provided on both sides of the back edge of the sliding lock 3, and a pair of sliding grooves 11 are provided on the corner of the first corner protection body 1, and the sliding feet 9 are connected in the sliding grooves 11. The cooperation between the sliding feet 9 and the sliding grooves 11 facilitates the sliding of the sliding lock.

[0045] Furthermore, a limiting protrusion 10 is further provided on the back of the sliding lock 3, and a limiting guide groove 12 is provided at the corner of the first corner guard body 1, and the limiting protrusion 10 is connected to the limiting guide groove 12. The limiting protrusion 10 and the limiting guide groove 12 cooperate to play a guiding and limiting role, and form a herringbone arrangement structure with a pair of the sliding feet.

[0046] Preferably, a pair of the slide grooves 11 and the limiting guide grooves 12 are both arranged parallel to the angle bisector of the corner guard, and the limiting guide grooves 12 are arranged on the angle bisector.

[0047] Furthermore, the front side of the sliding lock buckle 3 is a curved surface structure, with raised sides and a concave middle part, and a plurality of anti-slip stripes 14 are provided on the curved surface structure, so that fingers can slide the sliding lock buckle 3 easily.

[0048] Furthermore, a raised pick-up portion 16 is provided at the front edge of the corner of the first corner protector body 1, and a pair of clamp arms are arranged at 90 degrees. The pick-up portion 16 facilitates separation of the first corner protector body 1 and the second corner protector body 2 after unlocking.

[0049] Furthermore, the front side of the first corner guard body 1 is provided with an accommodating groove 15 at the corner portion, the first lock hole 4, the slide groove 11 and the limiting guide groove 12 are all arranged within the range of the accommodating groove 15, the sliding lock buckle 3 is installed in the accommodating groove 15, and the arc surface structure on the front side of the sliding lock buckle 3 is slightly higher than the accommodating groove 15.

[0050] Furthermore, the second corner guard body 2 is provided with a pair of through grooves 8 at the corner portion, and the pair of through grooves 8 are located on both sides of the connecting column 6; the internal locking tongue can be seen through the through grooves 8 for easy insertion and connection, and the through grooves 8 can also be used to install the entire corner guard on certain door and window frames.

[0051] Furthermore, the clamping arm of the first corner guard body 1 is provided with a T-shaped connecting groove 17 along the length direction, and the clamping arm of the second corner guard body 2 is provided with a mounting groove 18 along the length direction, and the T-shaped connecting groove 17 is arranged opposite to the mounting groove 18. The magnetic strip can be installed by using the T-shaped connecting groove 17 and the mounting groove 18, and the window screen can be fixed by using the magnetic strip.

[0052] In some embodiments, the overall length of the corner guard is 35-45mm, preferably 39.5*39.5mm, the width of the clamp arm is 14-18mm, preferably 15.9mm; the thickness of the first corner guard body is 4-5mm, preferably 4.15mm, the thickness of the second corner guard body is 2.5-3.5mm, preferably 3mm, the length of the connecting column is about 4mm, and the thickness of the locking tongue is 1.2mm.
