Description

Technical Field

[0001] This invention relates to the field of quality testing equipment technology, specifically to a testing device for testing the locking angle and torque of furniture connectors. Background Technology

[0002] As essential items in daily life, furniture is something consumers consider from multiple aspects such as style, material, and function when purchasing. Once consumers have determined their basic purchase intention, they will ultimately start with two basic requirements for furniture: aesthetics and sturdiness.

[0003] Furniture manufacturers are well aware that the unsightly and unstable conditions of existing furniture products are caused by technical defects in the three-in-one connectors. When furniture is moved or disassembled and reassembled, improper handling can generate significant leverage between the panels, easily causing the embedded parts to twist left and right. When the twisting amplitude exceeds a certain limit, the embedded holes in the panels will expand. Since wood itself does not have resilience, when the twisting amplitude of the embedded parts exceeds the limit, the expanded embedded holes lose the tension and fixing force between them and the embedded parts, resulting in damage and loosening of the furniture connections. Moreover, if repairs are not made using methods such as applying glue, the firmness of the furniture connections cannot be guaranteed, eventually leading to complete damage and scrapping.

[0004] The strength, locking angle, and maximum torque of the three-in-one furniture connectors will affect the stability of the connectors during furniture assembly. However, the locking angle and maximum torque of the three-in-one connectors are different due to different materials, sizes, and manufacturing processes. It is essential to measure and test the locking angle and torque strength of the three-in-one furniture connectors, as this will affect or even determine the stability of the furniture assembly.

[0005] Therefore, there is an urgent need to design a new test device that can simultaneously measure the locking angle and torque of the three-in-one connector to solve the current practical technical problems. Summary of the Invention

A through hole 120 for fixing knob is opened in the middle of the measuring support fixing block 104. When the connecting slider 103 approaches the measuring support fixing block 104, it drives the cylindrical mounting knob 115 to be inserted into the through hole 120, so that the connecting slider 103 and the measuring support fixing block 104 are in contact.

[0049] like Figure 6 , 7 As shown, a test device for testing the locking angle and torque of furniture connectors includes a locking angle direct reading scale 2 comprising a locking angle direct reading scale block 201.

[0051] like Figure 10 , 11As shown, a testing device for testing the locking angle and torque of furniture connectors includes a digital torque wrench 4 comprising an automatic torque digital display 401. The front end of the automatic torque digital display 401 is connected to a wrench force-bearing connecting rod 402 via a wrench connecting rod 406, and the rear end is connected to a torque wrench force-bearing handle 403 via the wrench connecting rod 406.

The automatic torque digital display 401 includes an automatic torque digital display screen 405, and a torque digital display control button 407 is installed on one side of the automatic torque digital display screen 405.

[0052] The main structure of the test device body 1, the locking angle direct-reading dial 2, the angle measuring pointer connector 3, and the digital torque wrench 4 is made of corrosion-resistant high-strength alloy steel. The corrosion-resistant high-strength alloy steel comprises the following raw materials by weight percentage: Mn 1.8%, Cu 1.9%, Cr 2.5%, Al 13%, Ti 4.8%, Ni 1.6%, Mo 0.7%, Zr 0.7%, Sc 0.6%, Ta 0.5%, Nb 0.3%, Ge 1.3%, Si 2.5%, Pt 0.9%, V 0.7%, Zn 1.5%, Se 1.2%, Rh 0.5%, Re 0.4%, Ce 0.12%, Nd 0.08%, Pr 0.1%, with the remainder being iron and trace impurities.

[0053] Furthermore, the connector mounting slider 103 has dial mounting and fixing slots 117 on both sides of the connector fixing mounting platform 105. The locking angle direct reading dial 2 is connected to the connector mounting slider 103 by inserting the dial long insert 202 and dial short insert 203 into the dial mounting and fixing slots 117. The locking angle direct reading dial 2 and the test device body 1 are connected by inserting the dial long insert 202 and dial short insert 203 into the dial mounting and fixing slots 117 on the connector mounting slider 103. The connector force-bearing insert 303 is inserted into the connector force-bearing insert 205 to connect the angle measuring pointer connector 3 and the locking angle direct reading dial 2. The wrench force-bearing insert 404 is inserted into the wrench force-bearing slot 304 to connect the digital torque wrench 4 and the angle measuring pointer connector 3.

[0054] A typical three-in-one furniture connector includes a connector eccentric body, a connector connecting screw 112, and a connector pre-embedded nut. The connector is inserted into the fixing block 111 and slides upward through the fixing block mounting groove on the force measuring slider 102 to be removed. The connector pre-embedded nut is hammered into the connector pre-embedded nut mounting hole of the connector insertion fixing block 111. The connector connecting screw 112 is then connected and fixed by threaded engagement with the connector pre-embedded nut. The connector is then inserted into the fixing block 111 and slides downward through the fixing block mounting groove on the force measuring slider 102 for installation. The connector connecting screw 112 is tightened by the connecting screw fixing knob 113.

[0055] The connector insertion fixing block 111 and the connector mounting cylinder 114 can be freely disassembled and assembled. Different models and sizes of connector insertion fixing blocks 111 can be selected according to different connector connecting screws and connector pre-embedded nuts. Different models and sizes of connector mounting cylinders 114 with connector eccentric mounting holes 119 can be selected according to different connector eccentric bodies.

[0056] In use, loosen the cylinder mounting knob 115 and the cylinder mounting screw assembly 118, select the appropriate connecting cylinder 114 with the connecting eccentric mounting hole 119, insert it into the connecting mounting platform 105, and fix the connecting cylinder 114 in the connecting platform 105 from the horizontal and vertical directions respectively by loosening the cylinder mounting knob 115 and the cylinder mounting screw assembly 118.

[0057] Align the twisted end of the furniture connector with the connector mounting cylinder 114 and the connector insertion fixing hole 121 on the connector mounting platform 105. After fixing the force measuring fixing block 101 and the force measuring slider 102, push the connector mounting slider 103 closer to the force measuring slider 102. Push the connector mounting slider 103 to insert the connector connecting screw 112 at the front end of the connector insertion fixing block 111 into the connector insertion fixing hole 121 at the front end of the connector mounting slider 103. The connector connecting screw 112 on the connector insertion fixing block 111 can be detached and replaced by the connecting screw fixing knob 113.

[0058] The connector insertion fixing block 111, inserted into the connector insertion fixing hole 121, is snapped together with the furniture connector to achieve the connection between the furniture connector and the connector connecting screw 112. The dial long insert 202 and dial short insert 203 are inserted into the dial mounting fixing slot 117 on the connector mounting slider 103 to achieve the installation connection between the locking angle direct reading dial 2 and the test device body 1. The connector force-bearing insert 303 is inserted into the connector force-bearing insert hole 205 to achieve the installation connection between the angle measuring pointer connector 3 and the locking angle direct reading dial 2. The wrench force-bearing insert 404 is inserted into the wrench force-bearing slot 304 to achieve the installation connection between the digital torque wrench 4 and the angle measuring pointer connector 3.

[0059] The torque digital display control button 407 is used to reset the data on the automatic torque digital display screen 405 to zero. After stabilization, the digital torque wrench 4 is rotated to drive the rotation of the angle measuring pointer connector 3. The front end of the connecting force rod 303 of the angle measuring pointer connector 3 is inserted into the screw groove at the top of the furniture connector, thereby driving the furniture connector to rotate. After rotating a certain angle, the furniture connector will be completely locked with the connecting screw 112 and cannot move, thus fixing the furniture connector. At this time, the angle measuring pointer 305 on the angle measuring pointer transparent disc 302 of the angle measuring pointer connector 3 will also rotate by the same angle and indicate an angle on the direct reading angle scale 204. This angle is the locking angle of the furniture connector.

[0060] Continue rotating the digital torque wrench 4. The furniture connector, which is stuck, will no longer rotate. At this time, the digital torque wrench 4 will drive the force-bearing rod 303 of the connector of the angle measuring pointer connector 3 to generate torque force on the furniture connector, thereby achieving torque failure of the furniture connection. The automatic torque digital display screen 405 on the digital torque wrench 4 will display the torque force and the magnitude of the torque at this time. Continue to apply force until the furniture connector is damaged. At this time, the maximum torque force and torque are measured. This torque force and torque are the maximum torque force and torque that the furniture connector can withstand.

[0061] Example 2

[0062] The difference between this embodiment and Embodiment 1 is that:

[0063] At the connection point between the force-measuring slider 102 and the connector mounting slider 103 and the measuring mounting slide rod 106, that is, at the connection point between the measuring mounting cylinder 116 and the measuring mounting slide rod 106, a slider fixing knob, similar to the distance adjustment rotary screw 109 and the cylindrical mounting fixing knob 115, is provided to fix the force-measuring slider 102 and the connector mounting slider 103 to the measuring mounting slide rod 106. Moreover, the measuring mounting slide rod 106 at this time has a slider fixing groove that cooperates with the slider fixing knob, thereby enabling the force-measuring slider 102 and the connector mounting slider 103 to be fixed on the measuring mounting slide rod 106 at any position.

[0064] The main structure of the test device body 1, the locking angle direct-reading dial 2, the angle measuring pointer connector 3, and the digital torque wrench 4 is made of corrosion-resistant high-strength alloy steel. The corrosion-resistant high-strength alloy steel comprises the following raw materials by weight percentage: Mn 1.1%, Cu 0.6%, Cr 0.9%, Al 5%, Ti 2.1%, Ni 0.6%, Mo 0.3%, Zr 0.4%, Sc 0.2%, Ta 0.1-0.5%, Nb 0.1%, Ge 0.7%, Si 1.1%, Pt 0.3%, V 0.2%, Zn 0.7%, Se 0.4%, Rh 0.2%, Re 0.1%, Ce 0.03-0.12%, Nd 0.04%, Pr 0.05%, with the remainder being iron and trace impurities.

[0065] In this invention, the testing device for testing the locking angle and torque of furniture connectors achieves simultaneous measurement of the locking angle and maximum torque of furniture connectors through a single device, minimizing interference between the two test items for the same furniture connector.
