Description

Technical Field

[0001] This utility model relates to a load-resistance force support, and more particularly to a load-resistance force adjustment connection device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] There is a type of stand used to fix and display products such as monitors. Therefore, the viewing angle needs to be moved frequently during use. In order to maintain the stability of the equipment, a device is needed to be installed inside the stand to provide load-bearing capacity to balance the weight of the fixed equipment.

[0004] However, the weight of different models of equipment to be fixed varies greatly. If the bracket can only provide a single load counterforce, it may not be able to achieve a balanced and stable adjustment of the bracket angle, affecting the user experience.

[0005] 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 solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a load counterforce adjustment connection device. By intervening in the load counterforce adjustment mechanism, the angle of the adjusting arm relative to the elastic element can be controlled by rotating the threaded rod, thereby achieving fine adjustment of the load counterforce feedback from the elastic element and exhibiting good balance.

[0007] To achieve the above objectives, this utility model discloses a load-resistance force adjusting connection device for connecting a first frame and a second frame, the load-resistance force adjusting connection device comprising:

[0008] A first arm has a first end and a second end that are disposed opposite to each other. The first end of the first arm is rotatably connected to the first frame, and the second end of the first arm is rotatably connected to the second frame.

[0009] The second arm has a first end and a second end that are disposed opposite to each other. The first end of the second arm is rotatably connected to the first frame, and the second end of the second arm is rotatably connected to the second frame. The second arm is arranged parallel to the first arm so that the second arm and the first arm form a parallelogram structure with their corresponding connection points.

[0010] A load-balancing force adjustment mechanism includes a threaded rod, an adjusting block, an adjusting arm, an elastic element, and a positioning element. The threaded rod is mounted on a first frame, the adjusting block is sleeved on the threaded rod, the adjusting arm has a first end and a second end opposite to each other, the elastic element has a first end and a second end opposite to each other, the first end of the adjusting arm is rotatably connected to the adjusting block, the second end of the adjusting arm is rotatably connected to the first end of the elastic element, the second end of the elastic element is fixedly connected to the first support arm, the positioning element is fixedly connected to the first support arm, and the elastic element passes through the positioning element so that the elastic element always remains parallel to the first support arm and the second support arm.

[0011] The extension direction of the adjusting arm is not parallel to the first arm, the second arm, or the elastic element.

[0012] As a further description of the above technical solution, the load counterforce adjustment mechanism also includes a fixing member, which is fixedly connected to the first support arm, and the second end of the elastic member is connected to the fixing member.

[0013] As a further description of the above technical solution, the threaded rod is disposed through the first frame, and one end of the threaded rod has a rotatable end.

[0014] As a further description of the above technical solution, the angle between the adjusting arm and the extending direction of the elastic element is between 0 and 90 degrees.

[0015] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0016] This utility model's load-resistance force adjustment connection device, through the intervention of a load-resistance force adjustment mechanism, controls the angle of the adjusting arm relative to the elastic element by rotating the threaded rod. When the angle of the adjusting arm relative to the elastic element is small, most of the load-resistance force provided by the elastic element can be transferred to the first frame and used to support the first arm, achieving balance for heavier installation equipment. When the angle of the adjusting arm relative to the elastic element is large, a small portion of the load-resistance force provided by the elastic element can be transferred to the first frame and used to support the first arm, achieving balance for lighter installation equipment. Simply put, this utility model, by adjusting the magnitude of the component force of the triangle, can support equipment with a wider weight range, and the adjustment only requires rotating the threaded rod, making it quite convenient.

[0026] Please see Figure 1-3 This embodiment provides a load-balance force adjustment connection device for connecting a first frame 100 and a second frame 200. The load-balance force adjustment connection device includes:

[0027] The first arm 1 has a first end and a second end that are disposed opposite to each other. The first end of the first arm 1 is rotatably connected to the first frame 100, and the second end of the first arm 1 is rotatably connected to the second frame 200.

[0028] The second support arm 2 has a first end and a second end that are arranged opposite to each other. The first end of the second support arm 2 is rotatably connected to the first frame 100, and the second end of the second support arm 2 is rotatably connected to the second frame 200. The second support arm 2 is arranged parallel to the first support arm 1.

[0029] The load counterbalancing force adjustment mechanism 3 includes a threaded rod 31, an adjusting block 32, an adjusting arm 33, an elastic element 34, and a positioning element 35. The threaded rod 31 is mounted on the first frame 100, the adjusting block 32 is sleeved on the threaded rod 31, the adjusting arm 33 has a first end and a second end that are arranged opposite to each other, the elastic element 34 has a first end and a second end that are arranged opposite to each other, the first end of the adjusting arm 33 is rotatably connected to the adjusting block 32, the second end of the adjusting arm 33 is rotatably connected to the first end of the elastic element 34, the second end of the elastic element 34 is fixedly connected to the first support arm 1, the positioning element 35 is fixedly connected to the first support arm 1, and the elastic element 34 is disposed through the positioning element 35 so that the elastic element 34 always remains parallel to the first support arm 1 and the second support arm 2.

[0030] The extension direction of the adjusting arm 33 is not parallel to the first arm 1, the second arm 2, and the elastic element 34.

[0031] With the above structure, the elastic element 34 itself has a factory-preset load-resistance force value before use, and it is not convenient to replace or adjust. The equipment used for installation may not match the load-resistance force fed back by the elastic element 34, potentially leading to overall instability and wobbling. To address this, the operator can fix one of the first frame 100 or the second frame 200 securely, and then install the equipment on the other frame. This allows the first frame 100 to transmit gravity to the threaded rod 31, and then through the adjusting block 32 to the adjusting arm 33. The adjusting arm 33 directly applies pressure to the first end of the elastic element 34. If the applied pressure is equal to the load-resistance force fed back to the adjusting arm 33 by the elastic element, the entire support system maintains a balanced and stable state. If the applied pressure is equal to the load-resistance force fed back to the adjusting arm 33 by the elastic element, the entire support system remains balanced and stable. If there is a difference in the load-resistance force, the first arm 1 and the second arm 2 cannot remain stable. At this point, the operator can rotate the threaded rod 31. Since the threaded rod 31 is fixed relative to the first frame 100, the adjusting block 32 is connected to the adjusting arm 33 and cannot rotate. The elastic element 34 is fixed to the first frame 100 by the positioning element 35 and also cannot rotate. Therefore, the adjusting block 32 fitted on the threaded rod 31 can move up and down, causing the adjusting arm 33 to rotate slightly relative to the first end of the elastic element 34. When the angle between the adjusting arm 33 and the elastic element 34 changes, according to the principle of force decomposition, if the load-resistance force provided by the first end of the elastic element 34 remains unchanged, and the direction of the adjusting arm 33 changes, the force it receives also changes. The elastic element 34 can then provide a stable load-resistance force to the adjusting block 32. This resistance force balances the weight of the external load. Therefore, by adjusting the angle of the adjusting arm 33, the operator can find the equilibrium point of the load-resistance force, at which point the rotation of the threaded rod 31 can be stopped.

[0032] During the above-mentioned use, the operator only needs to control the rotation of the threaded rod 31 to achieve the change of the load counterforce value provided by the elastic element 34. This makes it easier to adjust the balance in this embodiment, so that the load counterforce adjustment connection device can be used to fix more equipment of different weights, thus expanding the scope of application.

[0033] Furthermore, the elastic element 34 is configured as a gas spring that is extendable at its second end. The gas spring can output a constant force to the adjusting block 32. The gas spring is a mature industrial product with stable performance. Of course, the gas spring is only one application form of the elastic element 34 in this embodiment. In other embodiments, the elastic element 34 can be configured as a conventional mechanical spring, such as a coil spring, without departing from the technical concept of this utility model.

[0034] Furthermore, such as Figure 1As shown, the load counterforce adjustment mechanism 3 also includes a fixing member 36, which is fixedly connected to the first support arm 1, and the second end of the elastic member 34 is connected to the fixing member 36. By using the fixing member as a transition member, the second end of the elastic member 34, which extends in a fixed direction, can be stably fixed to the first support arm 1, maintaining the parallel relationship between the elastic member 34 and the first support arm 1.

[0035] Furthermore, a pad 4 is provided at the point where the first arm 1 faces the second arm 2. The pad 4 is used to buffer the contact between the first arm 1 and the second arm 2. In some cases, the first frame 100 may need to contact the second arm 2 due to requirements such as limiting the position inside. In this case, the pad 4 at the contact point can effectively alleviate the wear caused by the contact.

[0036] Furthermore, the threaded rod 31 is disposed through the first frame 100, and one end of the threaded rod 31 has a rotatable end. The end of the threaded rod 31 with the end is disposed at the bottom of the easily operable first frame 100, so that the operator can control the rotation of the threaded rod 31 by rotating the end.

[0037] Furthermore, the angle between the adjusting arm 33 and the extending direction of the elastic element 34 is between 0 and 90 degrees. That is, the adjusting arm 33 is neither parallel nor perpendicular to the extending direction of the elastic element 34, so as not to affect the force relationship.

[0038] Furthermore, the bottom of the first support arm 1 is provided with a detachable cover plate structure. With the above structure, the elastic element 34 can be quickly replaced or maintained by removing the cover plate at the bottom of the first support arm 1, which improves the convenience of later maintenance.
