Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, and in particular to a push-pull testing device for a monitor bracket. Background Technology
[0002] As a key component supporting and enabling flexible monitor positioning, the performance stability of the monitor arm directly impacts the user experience and product reliability. During production, rigorous lateral push-pull tests are required on the arm to assess key indicators such as the durability of its joint structure, damping consistency, and displacement hysteresis after long-term use. Currently, most manufacturers still rely on manual methods for this test: operators repeatedly apply push-pull forces to the monitor arm, simulating horizontal adjustment movements in actual use. This manual operation makes it difficult to precisely control the force, speed, and stroke of each push-pull, leading to inconsistent test conditions, unreproducible test results, and severely reducing data comparability and evaluation effectiveness. Furthermore, prolonged repetitive operations can easily cause operator fatigue, further exacerbating operational errors, and may even cause abnormal damage to the sample due to excessive force or angular deviations, affecting the accuracy of fault analysis. In addition, manual testing is extremely inefficient, failing to meet the needs of rapid, batch sampling or full inspection in large-scale production, becoming a bottleneck for capacity expansion. Although some simple testing equipment exists on the market, its functions are relatively simple, and most of them are limited to unidirectional or fixed-stroke mechanical motion. They cannot simulate the complex and ever-changing combined load and motion conditions in real use, and it is especially difficult to achieve adaptive testing of products with different specifications and different damping models.
[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a monitor bracket push-pull test device to solve the above problems.
[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content
[0005] To overcome the shortcomings of the prior art, the present invention discloses a monitor bracket push-pull testing device that can automatically, accurately, and repeatedly perform left and right push-pull tests.
[0006] This utility model discloses a push-pull testing device for a monitor bracket, including a mounting frame with an axially intersecting horizontal moving module and a vertical moving module. The moving end of the horizontal moving module has a transition plate, on which a lifting plate is connected via a vertical slide rail. A lifting push rod mechanism is located on the lower side of the lifting plate on the transition plate, with its output end connected to the lower end of the lifting plate. The front end of the lifting plate has a horizontal slide rail, on which a first mounting seat for connecting to the front end of the monitor bracket is slidably connected. Horizontal push rod mechanisms are symmetrically arranged on the left and right sides of the first mounting seat on the lifting plate, with their output ends abutting against the first mounting seat. The moving end of the vertical moving module has a second mounting seat for connecting to the rear end of the monitor bracket. It should be noted that the front end of the monitor bracket refers to the end assembled with the monitor, and the rear end refers to the end connected to the fixed base supporting the monitor bracket. Here, "axially intersecting" means that the extended lines of the conveying direction of the horizontal moving module and the vertical moving module intersect.
[0007] Preferred technical solution: The moving end of the horizontal moving module is driven by a motor in conjunction with a transmission belt.
[0008] Preferred technical solution: The moving end of the vertical moving module is driven by a motor in conjunction with a transmission screw.
[0009] Preferred technical solution: The lifting push rod mechanism is movably connected to the lower end of the lifting plate, and a counterweight for simulating the weight of the display is detachably provided on the first mounting base.
[0010] Preferred technical solution: The first mounting base is detachably provided with a monitor simulation connector, which is used to connect to the front end of the monitor bracket.
[0011] Preferred technical solution: The horizontal push rod mechanism and the lifting push rod mechanism are either electric push rods or cylinders.
[0012] Preferred technical solution: Pressure sensors are provided at the front end of the horizontal push rod mechanism.
[0013] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
[0014] This invention achieves high-precision, automated push-pull testing of monitor brackets by setting up horizontal and vertical moving modules that intersect axially, along with a multi-directionally adjustable mounting base structure and push rod mechanism, significantly improving test consistency and reliability. The horizontal push rod mechanism is symmetrically arranged on both sides of the first mounting base, simulating left and right push-pull movements in actual use. Pressure sensors monitor the applied force in real time, ensuring precise control of force, stroke, and speed for each test, greatly improving data comparability and repeatability. Simultaneously, the lifting push rod mechanism and counterweight allow the device to flexibly simulate the load conditions of monitors of different weights, adapting to the testing needs of various product specifications. The coordinated operation of the vertical and horizontal moving modules enables compatible testing of various monitor bracket models and also allows for composite motion testing, comprehensively evaluating the bracket's performance in complex usage environments. This device has a reasonable structure and is easy to operate, effectively avoiding sample damage and data distortion caused by fatigue or operational deviations in manual testing, and significantly improving testing efficiency. It is suitable for rapid sampling or full inspection in large-scale production. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a monitor bracket push-pull testing device, including a mounting bracket 1 on which a horizontal moving module 2 and a vertical moving module 3 are mounted. The main components of this utility model will be described in detail below:
[0028] The horizontal moving module 2 is driven by a motor and a transmission belt to move its moving end, on which an adapter plate 4 is mounted. The adapter plate 4 is connected to the lifting plate 5 via a vertical slide rail. The lifting push rod mechanism 6 is mounted below the adapter plate 4, and its output end is connected to the lower end of the lifting plate 5 to control the up and down movement of the lifting plate 5. The front end of the lifting plate 5 is provided with a horizontal slide rail, and the first mounting seat 7 is slidably connected to the horizontal slide rail. The first mounting seat 7 is used to connect to the front end of the display bracket 100. Horizontal push rod mechanisms 8 are symmetrically mounted on the left and right sides of the lifting plate 5. Their output ends can abut against the first mounting seats 7, pushing them to slide left and right along the horizontal slide rail. The front end of the horizontal push rod mechanism 8 is provided with a pressure sensor 12 for real-time monitoring of the applied force.
[0029] The vertical moving module 3 is driven by a motor and a transmission screw to move its moving end up and down. The moving end is provided with a second mounting base 9 for connecting to the rear end of the display bracket 100.
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the usage method is as follows: the positions of the first mounting base 7 and the second mounting base 9 are adjusted by the horizontal moving module 2 and the vertical moving module 3, and the front and rear ends of the monitor bracket 100 are connected to the first mounting base 7 and the second mounting base 9 respectively. The horizontal push rod mechanism 8 is controlled to apply thrust on both sides of the first mounting base 7 in turn to simulate the left and right movement in actual use. At the same time, the pressure sensor 12 records the data to realize the automated testing of the bracket performance.
[0031] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lifting push rod mechanism 6 is movably connected to the lower end of the lifting plate 5. A counterweight 10, detachably mounted on the first mounting base 7 to simulate the weight of the monitor, is used to more realistically test its load-bearing capacity on the monitor. During testing, the lifting push rod mechanism 6 pushes the lifting plate 5 upwards a certain distance. Then, the output end of the lifting push rod mechanism 6 disengages from the lifting plate 5 and resets. The monitor bracket 100 supports the lifting plate 5, and the weight of the lifting plate 5 is adjusted by the counterweight 10 to approximate the actual weight of the monitor. During the left-right push-pull test, the failure of the monitor bracket 100 to support the monitor is simultaneously detected.
[0032] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first mounting base 7 is detachably provided with a display simulation connector 11, which is used to connect to the display bracket 100 to simulate and test the stability of the connection between the display bracket 100 and the display.
[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
