Description

Technical Field

[0001] This utility model relates to the technical field of door and window size detection equipment, specifically a door and window size detection device. Background Technology

[0002] As an important component of buildings, the accuracy of door and window dimensions directly affects the building's airtightness, safety, and aesthetics. Dimensional inspection is a crucial step in the manufacturing process of doors and windows. Traditional inspection methods primarily rely on two calipers assembled in an "L" shape, but this method has significant limitations.

[0003] First, traditional inspection devices require inspecting each of the four outer and inner sides of doors and windows individually. This process is not only time-consuming but also reduces overall inspection efficiency. On a fast-paced production line, this inefficient inspection method can lead to production delays and increase operating costs for businesses.

[0004] Secondly, traditional testing methods are greatly affected by operator experience and the testing environment. Differences in the operator's skill level and experience can also lead to inconsistencies in test results. These factors can all cause deviations in test results, thereby affecting the installation and use of doors and windows.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing testing devices. Utility Model Content

[0006] This utility model addresses the problem that existing technical solutions are too simplistic by providing a door and window size detection device that is significantly different from existing technologies, thus solving the problems mentioned in the background.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a door and window size detection device, including a support frame, wherein a plurality of mounting grooves are equally spaced within the support frame, and a cover frame is connected to the side hinge of the support frame; a plurality of through-holes penetrating the upper and lower end faces are equally angled on the cover frame, and a sliding rod is connected to each through-hole; and a set of positioning structures is provided between the outer wall of each sliding rod and the through-hole; and a reset structure is provided within the cover frame, and the reset structure is used to cooperate with the positioning structure.

[0008] Preferably, the mounting groove is configured as a plurality of square grooves with progressively increasing dimensions, and the mounting groove has a stepped cross-section when viewed from the inside of the support frame.

[0009] Preferably, the cover frame is configured as a U-shaped structure, and each of the four sides of the cover frame is connected to an extension block in a cross shape.

[0010] Preferably, the positioning structure includes a slider, a movable block, a movable groove, a return spring, a retaining groove, a pressure spring, a toothed block, and a toothed groove. Each slider is slidably connected to its outer wall, and each slider has a movable block connected to both sides. Each movable block is engaged and slidably connected to the movable groove. The movable groove is opened on both sides of the opening, and a return spring is connected between the movable groove and the movable block. Each slider has a retaining groove on both sides, and a pressure spring is connected to each retaining groove. Each pressure spring has a toothed block connected to its end, and the toothed block is engaged in the toothed groove. The toothed groove is opened on the outer wall of the slider.

[0011] Preferably, the T-shaped end of the tooth block is slidably connected to the slot, and the other tooth end of the tooth block is connected to the slot. Furthermore, one side of the tooth block is configured as an inclined structure for cooperating with the reset structure.

[0012] Preferably, the reset structure includes a slot, a piston, a pressing rod, a pressing spring, a liquid channel, a branch, and a piston push rod. The slot is provided inside the cover frame, and a piston is provided inside the slot. A pressing rod is connected to the piston, and the end of the pressing rod passes through the end face of the cover frame away from the support frame and is connected to a pressing spring. The pressing spring is connected to the cover frame. A liquid channel is connected to the side of the slot, which surrounds the inside of the cover frame. A branch is provided between the liquid channel and each opening. A piston push rod is slidably connected in each branch, and the end of the piston push rod is used to insert into the slot to squeeze the toothed block to move.

[0013] Compared with existing technologies, the advantages of this invention are: the door and window size detection device, through the design of the support frame, mounting groove, and cover frame, makes the detection process simpler and more efficient. Specifically, when it is necessary to detect doors and windows of different sizes, simply place the door or window in the mounting groove that matches its size. This step allows the detection device to quickly capture the outer length and width of the door or window, providing convenience for preliminary detection.

[0014] Furthermore, by closing the cover frame and the support frame, the door and window are securely fixed between them, forming a closed testing space. This design not only ensures the stability of the testing but also provides a foundation for subsequent accurate measurements.

[0015] Furthermore, the positioning and resetting structures work together to enable the measurement of the inner dimensions of doors and windows. By adjusting the distance from the slider to the center of the cover frame and referring to the scale values ​​on the cover frame, the operator can easily determine the size of the inner dimensions of the doors and windows. This innovative design greatly simplifies the complex measurement process in traditional inspection.

[0016] Meanwhile, the combined use of the slider and scale values, along with the fixed values ​​in the mounting slots where the doors and windows are located, allows the inspector to quickly calculate the width from the inside to the outside of the doors and windows. This design not only improves the accuracy of the inspection but also significantly enhances its efficiency, making the entire inspection process smoother and more efficient.

[0017] In summary, this new type of testing device, through its unique structural design, enables rapid and accurate detection of door and window dimensions, greatly optimizing the production process, reducing operational difficulty, and improving production efficiency. Attached Figure Description

[0027] The cover frame 3 is designed as a loop shape, and each of the four sides of the cover frame 3 is connected to an extension block in a cross shape.

[0028] The positioning structure 6 includes a slider 601, a movable block 602, a movable groove 603, a return spring 604, a slot 605, a pressure spring 606, a toothed block 607, and a toothed groove 608. Each slider 5 has a slider 601 slidably connected to its outer wall, and each slider 601 has a movable block 602 connected to each side. Each movable block 602 is engaged and slidably connected to the movable groove 603. The movable groove 603 is opened on both sides of the through opening 4, and a return spring 604 is connected between the movable groove 603 and the movable block 602. Each slider 601 has a slot 605 on both sides, and a pressure spring 606 is connected to each slot 605. Each pressure spring 606 has a toothed block 607 connected to its end, and the toothed block 607 is engaged in the toothed groove 608. The toothed groove 608 is opened on the outer wall of the slider 5.

[0029] The T-shaped end of the toothed block 607 is engaged and slidably connected with the slot 605, and the other tooth end of the toothed block 607 is engaged and connected with the toothed groove 608. Furthermore, one side of the toothed block 607 is configured as an inclined structure for cooperating with the reset structure 7.

[0030] The reset structure 7 includes a slot 701, a piston 702, a pressing rod 703, a pressing spring 704, a liquid passage 705, a branch 706, and a piston push rod 707. The slot 701 is provided inside the cover frame 3, and the piston 702 is provided inside the slot 701. The pressing rod 703 is connected to the piston 702, and the end of the pressing rod 703 passes through the end face of the cover frame 3 away from the bearing frame 1 and is connected to the pressing spring 704. The pressing spring 704 is connected to the cover frame 3. A liquid passage 705 is connected to the side of the slot 701, which surrounds the inside of the cover frame 3. A branch 706 is provided between the liquid passage 705 and each opening 4. A piston push rod 707 is slidably connected in each branch 706, and the end of the piston push rod 707 is used to insert into the slot 605 to squeeze the tooth block 607 to move.

[0031] Working principle: According to Figure 1 As shown, the door and window to be tested are first placed into the mounting groove 2 of a suitable size on the support frame 1. The outer length and width of the door and window are quickly measured by the fixed size of the mounting groove 2. Then, the cover frame 3 is closed by the hinge so that the door and window are located between the support frame 1 and the cover frame 3.

[0032] When the user presses the pressing rod 703, the pressing spring 704 is compressed, causing the hydraulic oil in the empty groove 701 to enter the hydraulic passage 705. In the flowing knife branch 706, the piston push rod 707 is pushed out of the branch 706. The end of the piston push rod 707 enters the slot 605 of the slider 601, squeezing the inclined surface of the tooth block 607, causing the tooth block 607 to disengage from the tooth groove 608. The piston push rod 707 pushes the slider 601 to move on the slide rod 5 to the end of the opening 4 near the cover frame 3.

[0033] Then the user slowly releases the pressing rod 703. Driven by the return spring 604, the movable block 602 moves back to its original position in the movable groove 603. At the same time, it drives the slider 601 to move away from the center of the cover frame 3 on the slider 5 until the lower end of the slider 601 contacts and fits the inside of the door and window in the mounting groove 2.

[0034] By observing the arrow above slider 601 and the corresponding scale value near the opening 4 on the cover frame 3, since the dimension from the inner side to the center of the middle diameter of the cover frame 3 is fixed, the inner dimension of the door / window can be determined by adding the distance the slider 601 moves from the opening 4 near the center of the cover frame 3 to the inner dimension of the middle diameter of the cover frame 3. Similarly, the width from the inner side to the outer side of the upper diameter of the door / window can be determined by the dimension from the arrow on slider 601 to the mounting groove 2 where the door / window is located. Releasing the pressing rod 703 resets the structure 7. When the toothed block 607 disengages from the compression limit of the piston push rod 707, it re-engages with the toothed groove 608. This prevents forgetting the test values ​​and facilitates recording the values. In addition, when testing doors and windows in the same batch, it is easy to adapt to other doors and windows in the same batch, thus improving the testing speed. If there are differences in the size of the doors and windows, there will definitely be a deviation between the test value and the position of the slider 601. Therefore, doors and windows with unqualified sizes can be quickly detected. This is the working principle of the door and window size testing device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
