Description

Technical Field

[0001] The utility model relates to the technical field of door and window installation tools, and particularly relates to a door and window lock point positioning tool. Background Art

[0002] The two-point lock structure is widely applicable to door and window products. The existing installation process is to determine the lock point position according to the position after the door (window) sash is closed or by using an object with a fixed length.

[0003] The structure of the common lock point locator in the prior art consists of an "L"-shaped rod and a spring piece installed at one end of the "L"-shaped rod. This tool is applicable to the installation of lock points on structures such as inward and outward casement windows, top and bottom casement windows, and plastic steel casement windows.

[0004] The lock point locator with the above structure will have the following problems after long-term use: the elasticity of its spring piece will decrease after long-term use. When this tool is installed on the window sash and abuts against the lock bean, if the elasticity of the spring piece decreases, this tool cannot be stably stuck in the groove of the window sash for installing the lock bean, thus affecting the positioning accuracy.

[0005] Therefore, a door and window lock point positioning tool is proposed. Content of the Utility Model

The sliding direction of the support bar is parallel to the central axis of the cross bar; an elastic telescopic member is arranged between the support bar and the vertical bar. The telescopic direction of the elastic telescopic member is parallel to the central axis of the cross bar, and the support bar and the vertical bar are connected by the elastic telescopic member.

[0009] Further, in the utility model, the elastic telescopic member includes a plurality of helical springs. The telescopic direction of any of the helical springs is parallel to the central axis of the cross bar; one end of any of the helical springs is connected to the vertical bar, and the other end is connected to the support bar.

[0010] Further, in the utility model, magnetic blocks are arranged at both ends of any of the helical springs. The two magnetic blocks are respectively connected to the support bar and the vertical bar, and the two magnetic blocks have the same magnetic property.

[0011] Further, in the present utility model, a chute adapted to the leaning rod is provided on the bottom surface, the extending direction of the chute is parallel to the central axis of the cross bar, and the leaning rod is slidably connected to the chute; a limiting rod is provided at one end of the chute away from the vertical rod.

[0017] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution:

[0019] A door and window lock point positioning tool, comprising a cross bar 101 and a vertical bar 201 installed at one end of the cross bar 101. The vertical bar 201 and the cross bar 101 are perpendicular to each other, and the vertical bar 201 and the cross bar 101 form an L-shaped structure. The cross bar 101 has a top surface 1011 and a bottom surface 1012, and a support bar 301 is installed on its bottom surface 1012. The support bar 301 is also perpendicular to the cross bar 101. The support bar 301 is slidably connected to the cross bar 101, and the sliding direction of the support bar 301 is parallel to the central axis of the cross bar 101. An elastic telescopic member 401 is installed between the support bar 301 and the vertical bar 201. The telescopic direction of the elastic telescopic member 401 is parallel to the central axis of the cross bar 101. The support bar 301 and the vertical bar 201 are connected by the elastic telescopic member 401.

[0020] Specifically, in this embodiment, the elastic telescopic member 401 includes a plurality of helical springs. The telescopic direction of any helical spring is parallel to the central axis of the cross bar 101. One end of any helical spring is connected to the vertical bar 201, and the other end is connected to the support bar 301. In other embodiments of this embodiment, the elastic telescopic member 401 can also use elastic objects such as air bags.

[0021] Refer to Figure 2 , when this tool is installed on the window sash 701 and abuts against the lock bean 801, if the elastic force of the helical spring decreases, this tool cannot be stably stuck in the groove of the window sash 701 where the lock bean 801 is installed, thus affecting the positioning accuracy. To solve this problem, a magnetic block 501 is installed at both ends of each helical spring. The two magnetic blocks 501 are respectively connected to the support bar 301 and the vertical bar 201, and the two magnetic blocks 501 have the same magnetic property. In this way, when the helical spring is used for a long time and its elastic force decreases, the repulsive force generated between the two magnetic blocks 501 with the same magnetic property will also act on the support bar 301. The support bar 301 tightly abuts against the lock bean 801 under the action of the spring force and this repulsive force, so that this tool is stably installed on the window sash 701.

[0022] To facilitate the installation of the support bar 301, a chute adapted to the support bar 3 is opened on the bottom surface 1012 of the cross bar 101 in this embodiment. The extending direction of the chute is parallel to the central axis of the cross bar 101, and the support bar 301 is slidably connected to the chute. This chute can be designed as a dovetail groove structure or a T-shaped groove structure, and the corresponding end of the support bar 301 connected to this chute should be designed as a dovetail block structure or a T-shaped structure.

[0023] To limit the displacement of the support bar 301, a limiting rod 601 is installed at the end of the chute away from the vertical bar 201. When this tool is not in use, the support bar 301 is always in contact with the limiting rod 601 under the action of the elastic telescopic member 401.

[0024] Working principle:

[0025] Refer toFigure 2 , before use, first push the support rod 301 to move it towards the vertical rod 201 until both the vertical rod 201 and the support rod 301 can be simultaneously clamped into the groove between the locking bean 801 and the window sash 701. Then release the support rod 301. Under the action of the spring force and the repulsive force generated by the two magnetic blocks 501, the support rod 301 tightly abuts against the locking bean 801, and then make the bottom surface 1012 of the cross bar 101 abut against the locking bean 801. Then move the lock point slidably installed on the window frame. Stop moving the lock point when the lock point abuts against the top surface 1011 of the cross bar 101, fix the lock point at this position with screws, and finally remove this workpiece.

[0026] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. And the changes and alterations made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
