Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, specifically to an overload automatic stress relief hinge for monitor brackets. Background Technology

[0002] A hinge is a connecting device installed at the joint of a monitor stand.

[0003] Existing monitor stand hinges are secured by tightenable bolts at the hinge joints. However, this connection method can lead to plastic deformation or internal structural damage to the monitor stand if the force at the joint exceeds a preset safety threshold. This can result in the stand breaking due to overload, leading to safety accidents. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an overload automatic stress relief hinge for monitor brackets to solve the technical problem that existing monitor bracket hinges are locked with bolts, which makes it impossible for the hinges at the joints of the monitor bracket to automatically relieve stress according to the force on the bracket, causing the bracket to break due to overload and thus leading to safety accidents.

[0005] According to the technical solution provided in the embodiments of this application, the overload automatic force relief protection hinge of the monitor bracket includes two sets of force relief components, which are correspondingly installed on both sides of the front support arm connecting shaft of the bracket. The pressure relief protection component includes an overload mechanism and an adjusting bolt; The overload mechanism is movably mounted in the adjustment groove on the rear support arm via two first elastic elements at the front and rear. The front end of the overload mechanism is provided with a ratchet groove arranged in a ring. The ratchet groove is engaged with a ratchet block on the connecting shaft of the front support arm, so that the ratchet block rotates along the ratchet groove in the ring and provides stress relief protection for the overloaded front support arm.

[0006] Furthermore, each of the ratchet grooves is also provided with a corresponding overload adjustment mechanism.

[0007] Furthermore, the overload adjustment mechanism includes a pressure relief block and a second elastic element, wherein the pressure relief block is movably installed in the pressure relief groove on the ratchet groove and abuts against the second elastic element installed in the pressure relief groove.

[0008] Furthermore, the front end of the pressure relief block has a beveled structure.

[0009] Furthermore, the front end of the connecting shaft is provided with a slot, and the overload rod on the overload mechanism extends into the slot.

[0010] Furthermore, the ratchet block is installed in the slot.

[0011] Furthermore, the rear end of the overload rod on the overload mechanism abuts against the front end of the adjusting bolt screwed to the outside of the rear support arm.

[0012] Furthermore, the first elastic element and the second elastic element are metal springs.

[0013] Furthermore, the elasticity of the adjacent second elastic elements of each pressure relief adjustment mechanism is set with a difference of 5N, and the elasticity difference of the second elastic elements increases in a step-like manner and is uniformly set along the axial direction.

[0014] In summary, the beneficial effects of this application are as follows: 1. By setting a stress relief protection component at the connection between the front support arm and the rear support arm of the monitor bracket, the overload mechanism on the stress relief protection component is movable and engaged in the connecting shaft slot. By rotating the adjusting bolt, the overload stress relief bearing capacity of the overload rod on the hinge at the joint of the monitor bracket is adjusted, thereby expanding the stress relief protection range of the hinge. Second, by setting corresponding overload adjustment mechanisms on the surface of each ratchet groove in the annular array at the front end of the overload rod on the overload mechanism, when the front support arm is subjected to overload force, the force relief block slides from the locked ratchet groove to the adjacent ratchet groove to release force, while the second elastic element with stepped elastic support force increases abuts against the force relief block, thereby protecting the overload sliding connection shaft from force release and improving the safety of hinge use.

Detailed Implementation

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] 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.

[0019] The monitor stand features an overload-resistant automatic stress-relief hinge, such as... Figure 1 and Figure 2 As shown, it includes two sets of stress relief protection components 100, which are correspondingly installed on both sides of the connecting shaft 210 of the front support arm 200 of the bracket, so that the corresponding stress relief protection components 100 provide synchronous stress relief protection for the hinge of the monitor bracket, thereby improving the safety of the monitor bracket.

[0020] like Figure 2 and Figure 3 As shown, the pressure relief protection assembly 100 includes an overload mechanism 110 and an adjusting bolt 120. The adjusting bolt 120 is screwed to the outside of the rear support arm 300 and abuts against the rear end of the overload mechanism 110, which is movably installed in the adjusting groove of the rear support arm 300. This allows the adjusting bolt 120 to be rotated, thereby adjusting the depth and abutting force of the overload rod 111 on the overload mechanism 110 into the slot 220 of the connecting shaft 210, thereby adjusting the pressure value of the overload pressure relief protection.

[0021] like Figure 4 and Figure 5 As shown, the overload mechanism 110 is movably mounted in the adjustment groove on the rear support arm 300 via two first elastic elements 114. The front end of the overload mechanism 110 is provided with a plurality of ratchet grooves 112 arranged in a ring. The ratchet grooves 112 are engaged with ratchet blocks 113 with a suitable structure installed in the slot 220 of the connecting shaft 210 of the front support arm 200. When the current support arm 200 rotates along the hinge, the ratchet blocks 113 installed in the slot 220 of the connecting shaft 210 rotate along the ring-shaped array of ratchet grooves 112, so that the pressure applied by the metal spring of the first elastic element 114 provides first-level force relief protection for the overloaded front support arm 200.

[0022] like Figure 3 and Figure 5As shown, each ratchet groove 112 surface is also provided with a corresponding overload adjustment mechanism 130, and each overload adjustment mechanism 130 includes a stress relief block 131 and a second elastic element 132. The stress relief block 131 is movably installed in the stress relief groove on the ratchet groove 112 and abuts against the second elastic element 132 installed in the stress relief groove. The front end of the stress relief block 131 has a beveled structure and is adapted to the end face of the ratchet block 113. The second elastic element 132 adjacent to each stress relief adjustment mechanism is metal. The spring elasticity is set with a difference of 5N, and the elasticity difference of the second elastic element 132 increases in a stepped manner and is uniformly arranged along the axial direction. This allows the force-relieving abutment block 131 to slide from the engaged ratchet groove 112 to the adjacent ratchet groove 112 when the front support arm 200 is subjected to an overload force. The second elastic element 132 with the stepped elastic support force increases abuts against the force-relieving abutment block 131, thereby providing secondary force relief protection for the overloaded sliding connection shaft 210 and improving the safety of the hinge.

[0023] The working principle of the overload automatic stress relief hinge of this utility model monitor bracket is as follows: By installing corresponding stress relief protection components 100 on the hinge at the connection between the front support arm 200 and the rear support arm 300 of the monitor bracket, the corresponding stress relief protection components 100 provide synchronous overload stress relief protection for the front support arm 200, thereby improving the hinge protection force of the monitor bracket. When it is necessary to adjust the overload load capacity of the hinge, by rotating the adjusting bolt 120 screwed to the outside of the rear support arm 300, the overload rod 111 of the overload mechanism 110, which is abutted at the front end of the adjusting bolt 120, moves forward along the adjusting groove, compressing the metal spring of the first elastic element 114, thereby adjusting the hinge of the monitor bracket. The overload lever 111 on the hinge at the joint has an overload relief bearing capacity, thereby expanding the relief protection range of the hinge; and corresponding overload adjustment mechanisms 130 are provided on the surface of each ratchet groove 112 in the annular array at the front end of the overload lever 111 on the overload mechanism 110, so that when the front support arm 200 is subjected to overload force, the relief block 131 slides from the engaged ratchet groove 112 to the adjacent ratchet groove 112 to relieve the force, and the second elastic element 132 with stepped elastic support force increases abuts against the relief block 131, thereby providing relief protection for the overload sliding connection shaft 210 and improving the safety of the hinge. By setting multi-level relief and adjustable bearing capacity on the monitor bracket hinge, the practicality of the monitor bracket is improved.

[0024] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
