Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, and in particular to a novel roller-type straight hinge. Background Technology

[0002] A single-bar hinge, also known as a single-bar tie-rod hinge, is generally used in home furnishings and outdoor products such as height-adjustable desks, folding chairs, folding beds, office chairs, massage beds, and sofas, serving to extend, adjust, and provide support.

[0003] A search revealed that Chinese utility model patent CN207023669U discloses a parallel-arm type lever-operated mechanical lifting table, comprising a panel, a base, at least one parallel lifting arm, at least one straight lever for locking the lifting arm's raising and lowering, and at least one gas spring for preventing the panel from rapidly descending. The lifting arm is connected at both ends to the panel and the base, respectively. The straight lever and gas spring are connected at one end to the base and the other end to the lifting arm. This lifting table not only has a simple structure, simplifying manufacturing and reducing production costs, but also allows operators to quickly and easily raise and lower the table, greatly improving its convenience and practicality. The lifting table allows the operator to lift the panel with assistance, extending the length and adjusting the angle of the straight lever to raise the parallel lifting arm. During the lifting process, the positioning pins of the straight lever sequentially engage in different position slots. When the operator releases the assistance force, the positioning pins of the straight lever are fixed, locking the panel's lifting height. During the descent of the lifting platform, the operator can assist in raising the panel to the highest position of the positioning pin. Then, by applying additional downward pressure, the lifting arm can be slowly and uniformly lowered to the lowest position. To achieve positioning during descent, the lifting arm can be raised again after reaching the lowest position to the desired height. The positioning pins on the pull rod can then be engaged sequentially in the desired height slots to achieve the desired height positioning of the lifting arm.

[0004] While existing single-bar adjustable desks can achieve height adjustment and positioning, their functions are relatively limited, only allowing for height adjustment. Furthermore, they generate significant noise during use, resulting in poor noise reduction and a subpar user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a novel roller-type single-piece pull hinge that addresses the above-mentioned defects of the prior art. It adopts a roller-type structure design and uses a torsion spring to cooperate with a static shaft to control the moving shaft to lock or disengage from the accordion-shaped outer shell, thereby realizing functions such as shifting, positioning and resetting, or resetting to any position. It has diversified functions, good quietness, and good user experience.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A novel roller-type single-piece pull hinge includes an accordion-shaped outer shell. An inner movable silent pull rod is slidably disposed within the accordion-shaped outer shell. The inner movable silent pull rod includes a left silent sleeve, a right silent sleeve, and a shift reset mechanism. The left and right silent sleeves are respectively installed on the left and right outer sides of the shift reset mechanism. The shift reset mechanism includes a torsion spring, a static shaft, a moving shaft, a retaining ring, a reset plate, and a main support. The torsion spring, static shaft, and moving shaft are all snapped onto the inner side of the main support. The reset plate and retaining ring are sequentially sleeved on the outer sides of the static shaft and moving shaft, and the moving shaft abuts against the torsion spring.

[0008] Preferably, the accordion-shaped outer shell has several gear shift card interfaces on both the left and right outer sides, and several square through holes on the front side of the accordion-shaped outer shell.

[0009] Preferably, the main support has a torsion spring retaining hole, a static shaft retaining hole, and a motion shaft movable through hole that are adapted to the torsion spring, the static shaft, and the motion shaft, respectively, and the ends of the torsion spring, the static shaft, and the motion shaft pass through the torsion spring retaining hole, the static shaft retaining hole, and the motion shaft movable through hole, respectively.

[0010] Preferably, the reset plate has a first shaft through hole and a second shaft through hole adapted to the static shaft and the motion shaft respectively, and the ends of the static shaft and the motion shaft pass through the first shaft through hole and the second shaft through hole respectively.

[0011] Preferably, the left and right silent sleeves are symmetrically arranged on the left and right outer sides of the main body bracket. Both the left and right silent sleeves have silent sleeve through holes for the motion shaft to pass through, and the end of the motion shaft passes through the silent sleeve through hole.

[0012] Preferably, one end of the accordion-shaped outer shell and one end of the main support are both connected to a fixing angle bracket by fixing rivets, and a rear mute sleeve is fitted on the outer side of the other end of the accordion-shaped outer shell, and one end of the main support extends out of the rear mute sleeve.

[0013] By adopting the above technical solution, the present invention provides a novel roller-type single-straight hinge with the following beneficial effects: An inner movable silent pull rod is slidably disposed within the accordion-shaped outer shell of the novel roller-type single-straight hinge. This inner movable silent pull rod includes a left silent sleeve, a right silent sleeve, and a shifting and resetting mechanism. The left and right silent sleeves are respectively installed on the left and right outer sides of the shifting and resetting mechanism. The torsion spring, static shaft, and moving shaft in the shifting and resetting mechanism are all snapped onto the inner side of the main support. A reset plate and a retaining spring are sequentially sleeved on the outer side of both the static and moving shafts. The moving shaft abuts against the torsion spring. The left and right silent sleeves are respectively installed on the left and right sides of the main support. The accordion-shaped outer shell protects the internal structure for safe operation and provides guidance. It can also be conveniently adjusted laterally. Internal lubricating oil is injected to lubricate the internal moving mechanism and also serves to reset and position the internal moving mechanism after it reaches its extreme position during forward or backward movement. The torsion spring, moving shaft, reset plate, and main support form a shifting mechanism to realize the shifting function, including gear shifting, gear disengagement, locking, and unlocking. The right-side silent sleeve, torsion spring, static shaft, main support, and accordion-shaped housing form a positioning mechanism to realize the positioning function. The torsion spring, static shaft, reset plate, and main support form a reset mechanism to realize the reset function. The roller structure design uses a torsion spring and static shaft to control the moving shaft to lock or disengage from the accordion-shaped housing, thereby realizing functions such as shifting, positioning, and reset, or reset to any position. It has multiple functions, good quietness, and a good user experience. Attached Figure Description

[0023] like Figure 1-4As shown, the novel roller-type single-piece hinge includes an accordion-shaped outer shell 11. An inner movable silent pull rod is slidably disposed inside the accordion-shaped outer shell 11. The inner movable silent pull rod includes a left silent sleeve 9, a right silent sleeve 3, and a shift reset mechanism. The left silent sleeve 9 and the right silent sleeve 3 are respectively installed on the left and right outer sides of the shift reset mechanism. The shift reset mechanism includes a torsion spring 4, a static shaft 5, a moving shaft 6, a retaining spring 7, a reset piece 8, and a main support 12. The torsion spring 4, the static shaft 5, and the moving shaft 6 are all snapped onto the inner side of the main support 12. The reset piece 8 and the retaining spring 7 are sequentially sleeved on the outer sides of the static shaft 5 and the moving shaft 6, and the moving shaft 6 abuts against the torsion spring 4. Understandably, the accordion-shaped outer shell 11 has several gear shift interfaces 13 on both the left and right outer sides, and several square through holes 14 on the front side. The accordion-shaped outer shell 11 serves to protect the internal structure and ensure safe operation. It can also facilitate the injection of lubricating oil into the internal moving mechanism (i.e., the shifting and resetting mechanism) for lubrication. It also serves as a guide for the rollers, shifting, resetting, and other strokes. Furthermore, it serves as a reset and positioning mechanism after the internal moving mechanism reaches its limit position when moving forward or backward. The accordion-shaped outer shell 11 and the shifting and resetting mechanism can be made of stainless steel or other materials, and this utility model does not limit them.

[0024] Specifically, the main support 12 has torsion spring locking holes 15, static shaft locking holes 16, and motion shaft movable through holes 17, which are respectively adapted to the torsion spring 4, static shaft 5, and motion shaft 6. The ends of the torsion spring 4, static shaft 5, and motion shaft 6 protrude from the torsion spring locking holes 15, static shaft locking holes 16, and motion shaft movable through holes 17, respectively. The reset plate 8 has first shaft through holes 18 and second shaft through holes 19, which are respectively adapted to the static shaft 5 and motion shaft 6. The ends of the static shaft 5 and motion shaft 6 pass through the first shaft through hole 18 and the second shaft through hole 19, respectively. The second shaft through hole 19; the left silent sleeve 9 and the right silent sleeve 10 are symmetrically arranged on the left and right outer sides of the main body bracket 12. The left silent sleeve 9 and the right silent sleeve 10 are each provided with a silent sleeve through hole 20 for the motion shaft 6 to pass through. The end of the motion shaft 6 passes through the silent sleeve through hole 20. One end of the accordion-shaped outer shell 11 and one end of the main body bracket 12 are connected to a fixing angle bracket 1 by fixing rivets 2. The other end of the accordion-shaped outer shell 11 is fitted with a rear silent sleeve 10. One end of the main body bracket 12 passes through the rear silent sleeve 10. Understandably, the torsion spring 4, motion shaft 6, reset plate 8, and main support 12 constitute the main components of the shifting mechanism, used to realize the shifting function, and play the roles of shifting, shifting, locking, and unlocking; the right-side silent sleeve 3, torsion spring 4, static shaft 5, main support 12, and accordion-shaped shell 11 constitute the main components of the positioning mechanism, used to realize the positioning (i.e., neutral) function; the torsion spring 4, static shaft 5, reset plate 6, and main support 12 constitute the main components of the reset mechanism, used to realize the reset function; the torsion spring 4, static shaft 5, reset plate 6, main support 12, and accordion-shaped shell 11 constitute the main components of the arbitrary position reset mechanism, used to realize the arbitrary position reset function; the right-side silent sleeve 3, left-side silent sleeve 9, and main support 12 constitute the main components of the silent mechanism, used to realize the silent function.

[0025] Understandably, this utility model has a reasonable design and unique structure. It adopts a roller structure design and uses a motion shaft 6, a torsion spring 4 and a static shaft 5 to engage or disengage from the accordion-shaped outer shell 11, thereby realizing functions such as shifting, positioning and resetting or resetting to any position. It has diversified functions, good quietness and good user experience.
