Description

Technical Field

[0001] The utility model belongs to the technical field of door and window hardware accessories, in particular to an anti-pry lock block for doors and windows. Background Art

[0002] In the prior art, all doors and windows are locked by the lock point on the leaf and the lock block on the frame. There are various forms of door and window lock blocks in the entire door and window industry, and most of the lock blocks only have the vertical anti-theft function, but ignore the horizontal anti-pry design. When locking, the lock point on the transmission is driven up and down by rotating the handle, so that the lock point smoothly enters the groove opened by the lock block on the frame during movement to achieve locking, thereby achieving a close combination of the frame and leaf. However, this combination method in the prior art has the following defects:

[0003] There is a risk that the locking point will fall out of the lock block groove, especially when the windows and door panels are facing bad weather conditions, which will cause the panels to shake. When shaking, the locking point may easily fall out, and the windows and door panels may open, posing a safety risk. Summary of the invention

[0004] The utility model provides a pry-proof lock block for doors and windows, so as to achieve the purpose of improving the anti-theft performance.

[0005] A door and window anti-theft lock block, the lock block is provided with a lock slot; the characteristics are:

[0006] A locking point entrance is provided on the lock block; the locking point entrance is connected to the lock slot; an anti-pry step is formed on the side wall of the lock slot, the anti-pry step is higher than the side wall of the lock slot; and the anti-pry step is located at the locking point entrance.

[0007] Furthermore, an inclined introduction surface is formed on the outer side of the locking point inlet.

[0008] Furthermore, a buffer surface is provided on the outer upper side of the locking block.

[0009] Furthermore, the locking block is integrally formed, and a demoulding groove is formed on the lower side of the locking block, and the demoulding groove is connected to the locking groove.

[0010] Furthermore, the demoulding groove is located at the bottom of the locking block on the lower side of the anti-pry step.

[0011] Furthermore, support platforms are respectively provided at the four lower corners of the locking block.

[0012] Furthermore, the upper surface and the outer side edge of the locking block are both formed with an extension table surface, which contacts the frame profile, so that the surface is neat and beautiful after installation.

[0013] Furthermore, the lower surface of the locking block is a plane, with arc-shaped surfaces connected at both ends of the plane, and screw fixing holes are provided on the locking block on both sides of the locking groove.

[0014] Furthermore, the door and window anti-theft lock block is made of No. 5 zinc alloy material.

[0015] Beneficial effects of the utility model:

[0016] The utility model provides an anti-pry step in the lock slot. When the lock point enters the lock slot, the window or door leaf is closed. When the leaf is closed, the anti-pry step can block the lock point from slipping out easily due to the lateral external force. When the leaf is opened normally, the lock point passes through the slope of the anti-pry step and slides out smoothly.

[0017] In summary, the anti-theft lock block for doors and windows provided by the utility model is easy to install, simple to maintain, and has reliable performance; it has good anti-theft performance and can prevent the door and window from opening due to a lateral force.

[0023] The technical solution of the present invention is further explained below through specific implementation methods.

[0024] Example 1

[0025] Referring to the attached drawings, the utility model provides a door and window anti-theft lock block, which is provided with a lock slot 1; characterized in that an extension table 10 is formed on the upper surface and the outer side edge of the lock block. The extension table 10 contacts the frame profile 8, so that the surface is neat and beautiful after installation.

[0026] A lock point inlet 5 is provided on the lock block, and an inclined introduction surface 5.1 is formed on the outer side of the lock point inlet, so that the lock point can enter the lock slot more easily; the lock point inlet 5 is connected to the lock slot 1; an anti-pry step 2 is formed on the side wall of the lock slot, and the anti-pry step 2 is higher than the side wall of the lock slot; and the anti-pry step 2 is located at the lock point entrance. In the lock slot, on one side of the lock point inlet 5, the lock slot is formed with an upper wall surface 1.1, and the anti-pry step 2 is located on the upper wall surface 1.1.

[0027] The locking block is integrally formed, and a buffer surface 4 is provided on the outer upper side of the locking block; a demoulding groove 6 is formed on the lower side of the locking block, and the demoulding groove is connected to the locking groove 1. The demoulding groove 6 is located at the bottom of the locking block under the anti-pry step 2.

[0028] The four corners of the lower side of the locking block are respectively provided with support platforms 7 to offset the errors that occur during processing.

[0029] The lower surface of the locking block is a plane, with arc-shaped surfaces connected at both ends of the plane, and screw fixing holes 3 are provided on the locking block at both sides of the locking groove.

[0030] When the utility model is used, the anti-pry lock block of the door and window is fixed on the frame profile 8 by screws through the screw fixing hole 3. When the door is locked, the locking point 9 on the transmission is driven to move by rotating the handle, and the locking point enters the lock groove 1 through the anti-pry step 2 from the locking point entrance 5 to achieve the closing of the window and door. In addition, the design of the buffer surface 4 structure makes the door play a buffering role when it contacts the lock block. When subjected to external force in the horizontal direction, the anti-pry step 2 blocks the locking point 8 to prevent it from falling out; when the door is opened, the locking point 8 slides out smoothly through the slope of the anti-pry step 2.
