Description

Technical Field

[0001] This utility model relates to the field of door and window quality testing technology, specifically to a strength testing device for alloy door and window frames. Background Art

[0002] Doors and windows are hailed as the eyes of a building, an essential component that not only provides rich decorative effects for the building facade but also plays a crucial role in controlling building energy consumption. As energy conservation in buildings gains increasing attention, the fundamental functions of doors and windows are receiving more and more emphasis.

[0003] Among the three performance characteristics of doors and windows, wind pressure resistance refers to the ability of exterior doors and windows to withstand wind pressure without damage when they are in a normally closed state, such as cracking, panel breakage, local yielding, adhesive failure, etc., as well as functional impairments such as loose hardware and difficulty in opening. Its performance test is to test the ability of the test piece to resist damage and functional impairment under instantaneous wind pressure.

[0004] The existing testing fixtures are too simple in structure, only having a clamping effect. During the extreme pressure test of doors and windows, the glass will break and fly backward, which may injure the staff. It is also very easy to cut fingers when cleaning it afterwards. Moreover, the fixtures are generally made of metal frames with a fixed structure, which can only be used for testing doors and windows of the same model and size, making them impractical. Utility Model Content

[0005] Based on the above description, this utility model provides a strength testing device for alloy door and window frames to solve the shortcomings of existing doors and windows in wind pressure resistance tests, which lack protective measures and have fixed models and poor practicality.

[0006] This utility model is achieved through the following technical solution:

[0007] A strength testing device for alloy door and window frames includes a base. A horizontally arranged groove is provided on the top surface of the base. A pair of fixed brackets are arranged opposite each other inside the groove. Both fixed brackets are vertically arranged and have clamping components on their opposite sides. The two sets of clamping components are tightly engaged with the two sides of the door and window frame. The back of both fixed brackets extends backward to form a shield with an arc-shaped top surface. The ends of the two shields are attached to each other to form a protective cover. The bottom part of the protective cover extends downward and has an opening at the center of the end face of the extended part. A storage box is provided at the bottom of the base and is located directly below the opening.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, there are two slides arranged at intervals, and a rotating shaft is rotatably installed inside each slide. Gears are arranged at the same end of the two rotating shafts and mesh with each other. The end of one of the rotating shafts extends to the side wall of the base and is equipped with a first drive motor. The bottom part of the fixing frame protrudes and is slidably inserted into the two slides respectively, and the rotating shaft is inserted into the insertion hole on the end face of the bottom protruding part of the fixing frame.

[0010] Furthermore, the rotating shaft is provided with threads, the insertion hole on the protruding part at the bottom of the fixing bracket is set as a threaded hole, and the thread structure on the rotating shaft extends to both sides with the center of the base as the boundary to form positive and negative thread sections, and the two fixing brackets are respectively set on the positive thread section and the negative thread section.

[0011] Furthermore, the clamping assembly includes two spaced partitions, and the end face of the fixing frame is also longitudinally arranged with multiple limiting grooves. Each limiting groove is provided with a lead screw. An adjusting shaft is also vertically arranged inside the fixing frame. The side wall of the adjusting shaft and the end of the lead screw are provided with matching helical gears. A second drive motor is arranged at the center of the front of the fixing frame. The output shaft of the second drive motor extends into the fixing frame and is connected to the adjusting shaft through the helical gear. The end of the partition extends into the limiting groove and is threadedly assembled with the lead screw.

[0012] Furthermore, a rectangular positioning groove is provided through the end face of the partition, and multiple slots are arranged on both sides of the end face of the partition near the positioning groove. All of the slots are connected to the inside of the positioning groove, and a locking block is slidably inserted into the slots located at the upper and lower ends of the partition. The two locking blocks abut against the top and bottom surfaces of the door and window frames, respectively.

[0013] Furthermore, each of the two shielding plates has a slot and an insert on its opposite side, and the slot and the insert are slidably connected to form a grooved assembly structure.

[0014] Furthermore, a metal protective mesh is also provided at the connection between the storage box and the opening.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] This application employs a movable clamping method to fix both sides of the door and window frame, allowing it to be adjusted according to actual needs. This makes it suitable for testing various door and window frames of different sizes.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] Combine Figure 1-4 As shown, a strength testing device for alloy door and window frames includes:

[0025] The base 1 has a rectangular workbench on the top surface, which is mainly used to fix and support other components. A sliding groove 11 is arranged horizontally on its top surface.

[0026] The fixed frame 2 is provided in pairs and is vertically installed inside the slide groove 11. The two fixed frames 2 can move relative to each other or in opposite directions.

[0027] The clamping assembly 3 has two pairs and is installed on two fixed brackets 2 respectively. It is mainly used to clamp and fix the edges of the door and window frames so as to conduct wind pressure resistance tests on the door and window frames.

[0028] Storage box 4, located below base 1, is mainly used to collect broken glass shards and fragments of door and window frames during the wind pressure test, so that staff can handle them in a centralized manner.

[0029] Specifically, there are two parallel sliding grooves 11, and a rotating shaft 12 is rotatably installed inside the sliding groove 11. The ends of the two rotating shafts 12 are equipped with gears that mesh with each other. One of the gears passes through the sliding groove 11 and is connected to the first drive motor 13 fixedly installed on the side wall of the base 1. Therefore, the two rotating shafts 12 can rotate synchronously.

[0030] The bottom part of the fixed frame 2 protrudes downward and is inserted into the slide groove 11. An insertion hole is provided on the side wall of the protruding part. The rotating shaft 12 is inserted into the insertion hole. At the same time, the rotating shaft 12 and the insertion hole are movably connected through a threaded structure, so as to achieve the purpose of driving the two fixed frames 2 to move by the first drive motor 13.

[0031] Based on the adjustment method mentioned by the two fixed brackets 2, which allows for relative or opposite movement, this embodiment also provides positive and negative thread sections on the rotating shaft 12, which are arranged symmetrically around the center of the base 1. The two fixed brackets 2 are respectively installed on the positive thread section and the negative thread section, thereby achieving the adjustment effect of relative or opposite movement.

[0032] The clamping assembly 3 includes two spaced partitions 31. On the opposite side of the fixing frame 2, there are multiple limiting grooves 21 arranged longitudinally. Each limiting groove 21 is equipped with a lead screw 22. The fixing frame 2 also has an adjusting shaft 23 inside. The outer wall of the adjusting shaft 23 and the end of each lead screw 22 are equipped with a matching helical gear structure. The two mesh with each other for transmission. A second drive motor 24 is installed on the side wall of the front of the fixing frame 2. The output shaft of the second drive motor 24 is inserted longitudinally into the fixing frame 2 and is connected to the adjusting shaft 23 by means of the helical gear, thereby forming a transmission structure that can drive each lead screw 22 by a single motor.

[0033] The bottom part of the partition 31 protrudes and is inserted into the limiting groove 21. The lead screw 22 is movably connected to its protruding part by means of a threaded structure. At the same time, the lead screw 22 can be set to a structure similar to the aforementioned rotating shaft 12, that is, the thread on the lead screw 22 is divided into positive and negative thread sections, so that the two partitions 31 can clamp or release the door and window frame. Moreover, this clamping structure with adjustable width can be used for a variety of different types of doors and windows, which enhances the applicability of the testing equipment.

[0034] In addition, the upper and lower ends of the door and window frames should also be fixed to prevent them from sliding downwards. Therefore, positioning grooves 32 are provided through both partitions 31. The two sides of the positioning grooves 32 are respectively arranged with slots 33. The slots 34 on the outside of the partitions 31 are inserted longitudinally into the positioning grooves 32 and their sides are respectively engaged in the slots 33, thereby forming a partition effect. The upper and lower slots 34 are used to abut against the top and bottom surfaces of the door and window frames respectively to form a fixed engagement effect, which enhances the stability of the door and window frames during testing.

[0035] In actual testing, the negative pressure is constantly increasing to test the ultimate compressive strength of the door and window frames. Therefore, during the test, it is inevitable that the glass windows will break and form a large amount of debris. These debris will be carried by the airflow and move towards the rear of the device. In order to protect the staff, an arc-shaped baffle plate 25 should be installed on the back of the fixed frame 2 with bolts for detachment. The end faces of the two baffle plates 25 are connected to each other to form a protective cover.

[0036] Meanwhile, since the two fixing frames 2 can move relative to each other or in opposite directions, the two shielding plates 25 also need to be equipped with a folding structure so that the size of the protective cover can be changed as the fixing frames 2 change. That is, matching slots and inserts are respectively set on the back of the two shielding plates 25, which are inserted and fixed to each other. Moreover, the bottom of the two shielding plates 25 also protrudes downward and forms a rectangular opening. This opening is inserted into the interior of the storage box 4 and is detachably connected to the storage box 4. The connection is also reinforced with wire mesh, so the airflow can be discharged upward, while glass shards with weight and various frame fragments will be left inside the storage box 4.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
