Description

Technical Field

[0001] This utility model relates to the field of testing machines, and in particular to a desktop tilting and lifting testing machine. Background Technology

[0002] In modern furniture manufacturing, the desktop, as a core component of various furniture pieces such as office desks, study desks, and conference tables, directly impacts the user experience and safety due to the stability of its height adjustment and flipping functions. To ensure that the desktop can smoothly adjust its height and flip during long-term use, and maintain structural stability and functional reliability even after repeated operation, rigorous testing of the desktop's height adjustment and flipping performance is essential after production. By simulating frequent height adjustment and flipping operations in real-world usage scenarios, problems in the desktop's structural design and component fit can be identified promptly, thereby ensuring product quality.

[0003] Currently, industry standards typically require two separate devices to perform desktop lifting and flipping tests. For lifting tests, the desktop is fixed to a dedicated lifting test device, and operations such as simulating pressing the lifting button and applying pressure to reset the desktop are used to test the responsiveness and stability of the lifting function. For flipping tests, the desktop is transferred to a flipping test device, and external force is used to flip it, verifying the load-bearing capacity and smoothness of rotation of the flipping structure. This separate testing method not only increases equipment procurement costs and production workshop space, but also requires frequent transfers of the desktop between the two devices, prolonging the testing process, reducing overall testing efficiency, and potentially causing unnecessary damage to the desktop due to improper operation during multiple transfers. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a desktop flip-lift test machine, which can effectively solve the technical problem that lifting and flipping tests usually need to be completed by two separate devices.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The desktop flip-and-lift test machine includes a base, a body, and a test frame. The body and the test frame are fixedly installed on the upper part of the base. The body and the test frame are combined to form a test area. It is also equipped with a flip component and a lifting component, which are located in the test area.

[0007] The lifting assembly includes a bottom fixing frame, an unlocking cylinder, and a pressing cylinder. Both the extension rods of the unlocking cylinder and the pressing cylinder are equipped with pressure blocks. The unlocking cylinder is installed on the side wall of the bottom fixing frame, which is installed at the bottom of the test area. The pressing cylinder is installed at the top of the test frame, with the extension rod of the pressing cylinder facing downwards.

[0008] The flipping assembly includes a rotary motor, a flipping arm, a telescopic cylinder, and a fixed rod. The rotary motor is installed inside the machine body, and the rotating shaft of the rotary motor extends to the test area. One end of the flipping arm is connected to the rotating shaft of the rotary motor. The telescopic cylinder and the fixed rod are installed at the end of the flipping arm away from the rotary motor. The telescopic cylinder and the fixed rod are arranged in parallel, and rollers are connected to the telescopic cylinder and the fixed rod.

[0009] Furthermore, the fixing frame includes a crossbeam, side plates, and connecting rods. The side plates are disposed at both ends of the crossbeam, and the connecting rods pass through the crossbeam and the side plates and are threadedly connected to the base.

[0010] Furthermore, the surface of the base is provided with several screw holes, and the connecting rod is connected to any one of the screw holes.

[0011] Furthermore, the unlocking cylinder is slidably connected to the fixed frame via a movable seat, and the side wall of the fixed frame is provided with a horizontal sliding groove, into which the movable seat is installed.

[0012] Furthermore, the movable seat is provided with a fastening screw, which extends through the movable seat into a horizontal slide groove, and a positioning block is provided at one end of the fastening screw that extends into the horizontal slide groove.

[0013] Furthermore, a pressure sensor is connected between the pressing cylinder and the pressure block.

[0014] Furthermore, a limit pin is provided on the bottom surface of the test area.

[0015] Compared with existing technologies, the advantages of this invention are: integrating the lifting and flipping testing functions of the desktop into a single device significantly reduces equipment investment costs and workshop space requirements, while also reducing the number of desktop transfer steps between different devices, thus significantly improving testing efficiency. The rollers of the telescopic cylinder and the fixed rod are located at the upper and lower edges of the desktop, respectively, forming a clamping contact with the desktop edges. When the rotary motor drives the flipping arm to rotate, the flipping arm applies a pushing force to the desktop edges through the rollers, thereby smoothly pushing the desktop to complete the flipping action. When testing the desktop lifting performance, the telescopic cylinder's telescopic rod retracts, causing the connected rollers to move away from the upper end of the desktop, preventing the rollers from interfering with the desktop's lifting process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The following is combined with Figures 1-6 A detailed description of the desktop tilting and lifting testing machine of this utility model is provided below:

[0025] The desktop flip-and-lift test machine includes a base 1, a body 2, and a test frame 3. The body 2 and the test frame 3 are fixedly installed on the upper end of the base 1. The body 2 and the test frame 3 are combined to form a test area 4. The machine is also equipped with a flip component and a lifting component, which are located in the test area 4.

[0026] The lifting assembly includes a bottom fixing frame, an unlocking cylinder 5, and a pressing cylinder 6. Both the telescopic rods of the unlocking cylinder 5 and the pressing cylinder 6 are equipped with pressure blocks 7. The unlocking cylinder 5 is installed on the side wall of the bottom fixing frame, which is installed at the bottom of the test area 4. The pressing cylinder 6 is installed at the top of the test frame 3, with the telescopic rod of the pressing cylinder 6 pointing downwards.

[0027] The flipping assembly includes a rotary motor, a flipping arm 10, a telescopic cylinder 8, and a fixing rod 9. The rotary motor is installed inside the machine body 2, and the rotating shaft of the rotary motor extends to the test area 4. One end of the flipping arm 10 is connected to the rotating shaft of the rotary motor. The telescopic cylinder 8 and the fixing rod 9 are installed at the end of the flipping arm 10 away from the rotary motor. The telescopic cylinder 8 and the fixing rod 9 are arranged in parallel, and rollers 11 are connected to the telescopic cylinder 8 and the fixing rod 9.

[0028] Flipping test: The rollers 11 of the telescopic cylinder 8 and the fixed rod 9 are located at the upper and lower edges of the table, respectively, forming a clamping contact with the edge of the table. When the rotary motor drives the flipping arm 10 to rotate, the flipping arm 10 applies a pushing force to the edge of the table through the rollers 11, thereby smoothly pushing the table to complete the flipping action.

[0029] Lifting Test: Unlock cylinder 5 can precisely press the lift button on table 15, triggering the lifting action of the tabletop. Depress cylinder 6 can press the tabletop down and reset it after the test, simulating the reset operation in actual use and ensuring the comprehensiveness of the lifting test.

[0030] Integrating the lifting and flipping tests of the desktop into a single device significantly reduces equipment investment costs and workshop space requirements. It also minimizes the need to transfer the desktop between different devices, thus significantly improving testing efficiency. When testing the desktop's lifting performance, the telescopic cylinder 8 retracts its telescopic rod, moving the connected roller 11 away from the top of the desktop. This prevents the roller 11 from interfering with the desktop's lifting process, achieving a seamless connection between lifting and flipping tests.

[0031] The mounting bracket includes a crossbeam 12, side plates 13, and connecting rods 14. Side plates 13 are located at both ends of the crossbeam 12. The connecting rods 14 pass through the crossbeam 12 and side plates 13 and are threadedly connected to the base 1. The side plates 13 limit the lateral displacement of the base 1 of the table 15. The surface of the base 1 has several screw holes. The connecting rod 14 is connected to any one of these screw holes. By connecting the connecting rod 14 to different screw holes according to the testing requirements of different sizes and models of desktops, the position of the mounting bracket on the base 1 can be quickly adjusted, thus adapting to the fixing requirements of the table 15, improving the compatibility of the equipment with various desktop specifications, and enhancing the flexibility of testing.

[0032] The unlocking cylinder 5 is slidably connected to the fixed frame via a movable seat. The side wall of the fixed frame is provided with a horizontal groove 17. The movable seat is installed in the horizontal groove 17, allowing for flexible adjustment of the horizontal position of the unlocking cylinder 5. By sliding the movable seat within the horizontal groove 17, the corresponding position of the unlocking cylinder 5 and the desktop lifting button can be precisely adjusted, ensuring that the pressure block 7 of the unlocking cylinder 5 can accurately press the button in different positions, adapting to the button layout of different desktop styles and improving the versatility of the device. A fastening screw 18 is provided in the movable seat, extending through the movable seat into the horizontal groove 17. A positioning block is provided at one end of the fastening screw 18 extending into the horizontal groove 17. The cooperation between the fastening screw 18 and the positioning block effectively fixes the position of the movable seat. After the unlocking cylinder 5 is adjusted to the appropriate position, tightening the fastening screw 18 makes the positioning block press firmly against the inner wall of the horizontal groove 17, preventing the movable seat from shifting due to vibration during testing, ensuring the accuracy of the unlocking cylinder 5 pressing the button, and improving the stability and reliability of the test.

[0033] A pressure sensor 16 is connected between the pressing cylinder 6 and the pressure block 7. The pressure sensor 16 can monitor the pressure value of the pressing cylinder 6 on the table in real time, which allows the operator to accurately control the downward pressure. During the table reset test, the output force of the pressing cylinder 6 can be adjusted based on the data fed back by the pressure sensor 16 to avoid damage to the table due to excessive pressure or incomplete reset due to insufficient pressure, thus ensuring the accuracy of the lifting test and providing quantitative basis for test data recording and quality analysis.

[0034] The bottom surface of the test area 4 is provided with a limiting pin, which can accurately position the desktop within the test area 4 to prevent the desktop from shifting in the front-back direction during the lifting or flipping test.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
