Technical Field

[0001] The utility model relates to the technical field of hinge manufacturing, in particular to a hinge load-bearing test tool. Background Art

[0002] Hinges are commonly used devices in the process of assembling a sofa with a folding function. The hinges can be used to fold and unfold the sofa, making it more convenient to use.

[0003] In order to ensure the quality of hinges, each batch of finished hinges needs to be sampled to test whether the bearing capacity of the hinges meets the standards. The factory now has two types of finished hinges with higher production. The first type of finished hinge has a fixed arm and a swing arm. The fixed arm is provided with a mounting hole, and the swing arm is provided with an angle code, which is connected to the frame screw of the sofa through the mounting hole; the second type of finished hinge has a bent rod and a swing arm. The swing arm is provided with an angle code, and the bent rod is inserted into the frame of the sofa, and then the second hinge is fixed by a nut; so the installation method of the first hinge and the second hinge is different. The existing load-bearing tests of the first hinge and the second hinge are carried out by independent test fixtures. The two test fixtures occupy a large space, so it is urgent to design a test fixture that can be compatible with the load-bearing tests of the first hinge and the second hinge at the same time.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a hinge load-bearing test fixture, so that both the first hinge and the second hinge can be tested by the hinge load-bearing test fixture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hinge load-bearing test fixture comprises a base plate, two vertical plates spaced apart on the base plate, and a flat plate placed flat and fixed on the two vertical plates, wherein the flat plate is provided with a positioning structure for positioning two first hinges, and when the two first hinges are mounted on the flat plate, the angle brackets of the two first hinges jointly support a first pad, and at least one counterweight is placed on the first pad; mounting holes for fixing second hinges are provided on the inner side surfaces of the two vertical plates, and when the two second hinges are respectively fixed to the corresponding vertical plates by mounting screws and the mounting holes, the angle brackets of the two second hinges jointly support a second pad, and at least one counterweight is placed on the second pad.

[0008] As a further improvement of the above technical solution, the positioning structure includes two washers and nuts, and two sockets symmetrically opened on the flat plate. The bent rod of the first hinge includes an L-shaped shaft segment, an optical axis segment connected to one section of the L-shaped segment, and a threaded segment connected to the optical axis segment. The diameter of the L-shaped shaft segment is larger than the diameters of the optical axis segment and the threaded segment. The aperture of the socket is smaller than the L-shaped shaft segment. After the bent rod of the first hinge is inserted into the socket, the threaded section is located below the flat plate. The washer is sleeved on the threaded section and cooperates with the nut to fix the first hinge.

[0009] As a further improvement of the above technical solution, the counterweight block is a thick plate-like structure, and recesses for people to carry the counterweight block are opened on the left and right end surfaces.

[0010] The counterweight block is a thick plate-like structure, and handles are provided on both end surfaces of the counterweight block.

[0011] The bottom plate is provided with a counterweight placement area located upstream of the flat plate, each counterweight is pasted with a weight label, and counterweights of the same weight are stacked.

[0012] As a further improvement of the above technical solution, the mounting hole is located downstream of the flat plate, forming a spacing area between the two, and the base plate is provided with a first safety baffle in the spacing area for preventing the counterweight block on the first pad from tipping forward.

[0013] As a further improvement of the above technical solution, a second safety baffle is provided on the bottom plate for preventing the counterweight block on the second pad from tipping forward.

DETAILED DESCRIPTION

[0023] The utility model provides a hinge load-bearing test tool. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] See also Figure 1-Figure 6 The utility model provides a hinge load-bearing test fixture, including a base plate 1, two vertical plates 2 spaced apart on the base plate 1, and a flat plate 3 placed flat and fixed on the two vertical plates 2, the flat plate 3 is provided with a positioning structure for positioning two first hinges 8, when the two first hinges 8 are installed on the flat plate 3, the angle codes of the two first hinges 8 jointly support a first pad 41, and at least one counterweight 5 is placed on the first pad 41; the inner side surfaces of the two vertical plates 2 are provided with mounting holes 21 for fixing second hinges 9, when the two second hinges 9 are respectively fixed to the corresponding vertical plates 2 by means of mounting screws and the mounting holes 21, the angle codes of the two second hinges 9 jointly support a second pad 42, and at least one counterweight 5 is placed on the second pad 42.

[0025] It is understandable that a sofa will be equipped with two identical hinges, and the sofa can be folded and unfolded through the two identical hinges. Even if the sofa is switched between the folded state and the unfolded state, when the sofa is in the unfolded state, people sit on the sofa and the hinges will bear the weight.

[0026] Therefore, the hinge load-bearing test tool provided by the utility model tests the first hinge 8 by matching two first hinges 8, and tests the second hinge 9 by matching two second hinges 9, simulating the load-bearing scenario of two identical hinges in actual use, and more objectively judging the hinge load-bearing performance. The hinge load-bearing test tool can be used to test the first hinge 8 and the second hinge 9 simultaneously without interfering with each other, which helps to improve work efficiency.

[0027] When testing the first hinge 8, the two first hinges 8 are mounted on the flat plate 3 and fixed by the positioning structure. At this time, the first hinge 8 is in the unfolded state, and the first pad 41 is placed on the corners of the two first hinges 8. Then, the counterweights 5 are gradually added to the first pad 41. With the increase of the counterweights 5, the load-bearing capacity of the two first hinges 8 also gradually increases. If the weight of the counterweight has not reached the set weight, the first hinge 8 is damaged and fails, which means that the tested first hinge 8 is unqualified. Until the weight of the counterweight reaches the set weight, the counterweight 5 will no longer be added. After the first hinge 8 continues to bear the weight for a period of time, it is not damaged and fails, then the first hinge 8 is a qualified product.

[0028] When testing the second hinge 9, the two second hinges 9 are fixed to the inner side of the corresponding vertical plate 2 by screws. At this time, the second hinge 9 is in the unfolded state, and then the second pad 42 is placed on the corner code of the two second hinges 9, and then the counterweights 5 are gradually added to the second pad 42. With the increase of the counterweights 5, the load-bearing capacity of the two second hinges 9 gradually increases. If the weight of the counterweight has not reached the set weight, the second hinge 9 is damaged and fails, which means that the tested second hinge 9 is unqualified. Until the weight of the counterweight reaches the set weight, the counterweight 5 will no longer be added. After the second hinge 9 continues to bear the weight for a period of time, it is not damaged and fails, then the second hinge 9 is a qualified product.

[0029] Specifically, the positioning structure includes two washers 62 and a nut 63, and two insertion holes 61 symmetrically opened on the flat plate 3. The bent rod 81 of the first hinge 8 includes an L-shaped shaft section 82, an optical shaft section 83 connected to the first L-shaped section, and a threaded section 84 connected to the optical shaft section 83. The diameter of the L-shaped shaft section 82 is larger than the diameters of the optical shaft section 83 and the threaded section 84, and the aperture of the insertion hole 61 is smaller than the L-shaped shaft section 82. When installing the first hinge 8, after the bent rod 81 of the first hinge 8 is inserted into the insertion hole 61, only the threaded section 84 passes through the insertion hole 61 and the threaded section 84 is located below the flat plate 3, while the L-shaped shaft section 82 of the bent rod 81 cannot pass through the insertion hole 61 and is located above the flat plate 3. At this time, the first hinge 8 can still rotate. In order to ensure that the first hinge 8 is in a completely fixed state during the test, the threaded section 84 is covered with the washer 62 and cooperates with the nut 63 to fix the first hinge 8.

[0030] In this embodiment, the counterweight block 5 is a thick plate-like structure, so the counterweight block 5 can also be called a weight steel. In order to facilitate the staff to carry the counterweight block 5, in one embodiment, the left and right end surfaces of the counterweight block 5 are provided with recesses for people to carry. In another embodiment, the left and right end surfaces of the counterweight block 5 are provided with handles 51.

[0031] In order to standardize the placement of the counterweight blocks 5 and facilitate the staff to carry the counterweight blocks 5, a counterweight block placement area 11 located upstream of the flat plate 3 is provided on the base plate 1, and a weight label is affixed to each counterweight block 5. The staff can clearly know the weight of each counterweight block 5 based on the weight label, and the counterweight blocks 5 of the same weight are stacked.

[0032] When testing the first hinge 8, as the number of counterweights 5 increases, the load borne by the angle code of the first hinge 8 will become larger and larger, and the following situations may occur on the first hinge 8: the first hinge 8 is damaged and fails before the real-time load-bearing capacity of the first hinge 8 reaches the rated load-bearing capacity, and the counterweight 5 on the first hinge 8 will suddenly tip forward, affecting the test of the second hinge 9 or injuring staff; the real-time load-bearing capacity of the first hinge 8 is maintained for a period of time after reaching the rated load-bearing capacity. If the first hinge 8 is damaged and fails, the counterweight 5 on the first hinge 8 will suddenly tip forward, affecting the test of the second hinge 9 or injuring staff.

[0033] In order to prevent the counterweight 5 on the first hinge 8 from suddenly falling forward, affecting the test of the second hinge 9 and injuring the staff, the mounting hole 21 is located downstream of the flat plate 3, and a spacing area is formed between the two. The base plate 1 is provided with a first safety baffle 71 in the spacing area for preventing the counterweight 5 on the first pad 41 from falling forward. Even if the counterweight 5 on the first pad 41 falls forward, the first safety baffle 71 will block the counterweight 5 and will not cause a safety accident.

[0034] Similarly, the bottom plate 1 is provided with a second safety baffle 72 for preventing the counterweight 5 on the second pad 42 from falling forward. Even if the counterweight 5 on the second pad 42 falls forward, the second safety baffle 72 will block the counterweight 5 and will not cause a safety accident.

[0035] In order to facilitate the fixing of the first safety baffle 71, the bottom plate 1 is provided with two first clamps 12, and a first slot 13 for inserting the first mounting baffle is provided between the two first clamps 12. The first safety baffle 71 is inserted into the first slot 13 to be in an upright state; similarly, the bottom plate 1 is provided with two second clamps 14, and a second slot 15 for inserting the second mounting baffle is provided between the two second clamps 14. The second safety baffle 72 is inserted into the second slot 15 to be in an upright state, which is easy to operate. When the first safety baffle 71 and the second safety baffle 72 are not in use, the first safety baffle 71 and the second safety baffle 72 are placed flat on the first clamp 12 and the second clamp 14, and the space between the two vertical plates 2 is used for storage.
