Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for building construction, and in particular to a doorplate installation locator for entrance doors. Background Technology

[0002] In the renovation and construction of residential and public buildings, the installation of entrance doorplates typically requires ensuring uniform levelness, height, and location within a specific position on the door panel. Traditional installation methods rely entirely on construction workers using measuring tapes, spirit levels, and manual marking for positioning, which has the following drawbacks: First, measurement and marking are performed in separate steps, making the process cumbersome and inefficient. Second, it is highly susceptible to human error, easily leading to positioning deviations, resulting in tilted or uneven doorplates, affecting the overall aesthetics. Third, when wall thickness varies or door frame designs are complex, it is difficult to quickly determine a uniform installation baseline. Therefore, there is an urgent need for a specialized tool that simplifies operation, improves positioning accuracy, and enhances installation efficiency.

[0003] Based on this, this utility model designs an entrance door number plate installation locator to solve the above problems. Utility Model Content

One end of the positioning plate is provided with a locking block, which forms an L-shaped structure with the positioning plate. An adjustment groove is opened along the length direction on the upper surface of the positioning plate. A positioning bolt is vertically installed in the adjustment groove. The positioning bolt passes through the elastic element, the positioning plate, and the positioning block from bottom to top. A fixing nut is installed at the end of the positioning bolt.

[0006] Furthermore, the elastic element includes an upper shell and a lower shell, which are cylindrical cover structures with cavities inside. A compression spring is vertically installed in the cavity. A first through hole and a second through hole are respectively opened on the upper shell and the lower shell. The positioning bolt passes through the second through hole, the compression spring, and the first through hole from bottom to top.

[0007] Furthermore, at least two limiting protrusions extend horizontally from the outer edge of the upper shell.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-5 As shown, this utility model is a doorplate installation locator for an entrance door, made of gypsum board, wood board, or engineering plastic. It includes a positioning plate 3 and a positioning block 4 mounted on the positioning plate 3. One end of the positioning plate 3 has a locking block 7, forming an L-shaped structure with the positioning plate 3. A through-type adjustment groove 8 is formed along the length of the upper surface of the positioning plate 3. A positioning bolt 9 is vertically installed in the adjustment groove 8, and the width of the adjustment groove 8 matches the diameter of the positioning bolt 9. The elastic element includes an upper shell 11 and a lower shell 12, which are cylindrical cover structures with internal cavities. A compression spring 14 is vertically installed in the cavity. A vertical limiting groove 17 is formed on the inner side wall of the upper shell 11, and an inwardly protruding limiting ring 19 is provided at the lower edge. A vertical limiting block 18 is provided on the outer side wall of the lower shell 12, and an outwardly protruding limiting ring 20 is provided at the upper edge. The vertical limiting groove 17 and the vertical limiting block 18 correspond to each other, allowing the upper shell 11 and the lower shell 12 to engage and be positioned. The upper shell 11 and the lower shell 12 are respectively provided with a first through hole 21 and a second through hole 22. The positioning bolt 9 passes through the second through hole 22, the compression spring 14 and the first through hole 21 from bottom to top. The inner diameters of the first through hole 21, the second through hole 22 and the compression spring 14 are all larger than the diameter of the positioning bolt 9. The positioning bolt 9 passes through the elastic element, the positioning plate 3 and the positioning block 4 from bottom to top. The end of the positioning bolt 9 is fitted with a fixing nut 10. The positioning bolt 9 can pass smoothly through and slide in the adjustment groove 8.

[0019] At least two limiting protrusions 13 extend horizontally from the outer edge of the upper shell 11 to facilitate the pressing of the elastic element.

[0020] The edges of the first through hole 21 and the second through hole 22 are respectively fixed to the upper limit ring 15 and the lower limit ring 16 of the compression spring 14 in the direction of the compression spring 14. The upper limit ring 15 and the lower limit ring 16 of the compression spring 14 are respectively inserted into the upper and lower ends of the compression spring 14 for limiting the compression spring 14.

[0021] Positioning line 5 is installed at the bottom of positioning plate 3. The length of positioning line 5 can be customized according to the required height. A counterweight block 6 is fixed at the end of positioning line 5.

[0022] In use, hold the positioning plate 3 with one hand. The L-shaped structure formed by the locking block 7 and the positioning plate 3 is locked onto the door frame to determine the horizontal and vertical reference of the locator. Move it up and down until the counterweight 6 is placed on the ground and the positioning line 5 is taut to determine the height of the locator. Press the limiting protrusion 13 on the elastic element with the index and middle fingers of the other hand, and fix the thumb on the lower end of the positioning bolt 9. Pinch the elastic element to make the upper shell 11 and lower shell 12 move closer to each other and compress the internal compression spring 14. At this time, the clamping force between the positioning block 4 and the positioning plate 3 is released, and the positioning block 4 can slide along the adjustment groove 8. After adjusting the position of the positioning block 4 according to the door size, release the pressure on the elastic element. The compression spring 14 returns to its original position and pushes the upper shell 11 and lower shell 12 back to their original position. The positioning block 4 is then clamped and fixed to the positioning plate 3 again by the positioning bolt 9 and the fixing nut 10. Then, align the edge of the doorplate with the reference edge of the positioning block 4. The installation position of the doorplate can then be marked on the door frame by the position of the positioning block 4. After positioning, remove the locator from the door frame and install the doorplate according to the marking.
