  In general, a door that is manually opened has two hinge pieces connected to the door main body and the door frame, respectively, and a rotating shaft provided between the two hinge pieces is combined with the user. The door body can be opened and closed manually. In some situations, for example, when the user rushes to open or close the door body, or when the door body is opened or closed due to an external force such as a strong wind, the door body and the wall / door frame are intense if excessive force is applied. There was a risk of unpleasant noise and even damage due to a sudden collision. In order to solve the above problems, a buffering mechanism is usually added to the rotary shaft between the two hinge pieces.

  However, after adding a buffering mechanism to the rotating shaft, it is generally impossible to readjust or control the buffering level. If the buffering level is too large, the user will consume too much power when opening and closing the door body.

  In order that the present invention may be fully understood, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. Those skilled in the art can understand the objects, features, and effects of the present invention from the contents disclosed in the present specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and various detailed descriptions in the present specification are based on different viewpoints and applications, and do not depart from the spirit of the present invention. Various modifications and changes can be made within. Further, the accompanying drawings of the present invention are merely conceptual descriptions of the present invention, and are not drawn based on the actual size. The following embodiments further describe in detail the related technical contents of the present invention, and the disclosed contents are not used to limit the claims of utility model registration of the present invention. This will be described later.

  FIG. 1 is a partially exploded perspective view of a hydraulic shock absorber 30 according to an embodiment of the present invention. As shown in FIG. 1, the hydraulic shock absorber 30 includes a shock absorber 31, a rotating component member 33, a flow rate control connecting member 313, a flow rate control adjusting member 315, and a housing 37. FIG. 2 is a partially exploded perspective view of the buffer part 31 according to an embodiment of the present invention.

  Referring to FIGS. 1 and 2 at the same time, the rotating component 33 is fitted and pivotally connected to the buffer portion 31 and is variable between the rotating component 33 and the top end 310 of the buffer portion 31. (Internal space indicated by reference numeral C in FIG. 3 described later) is formed. The flow rate control connecting member 313 penetrates the through hole 31H at the center of the top end of the buffer portion 31, and the flow rate control connecting member 313 includes a flow hole 313H. The flow rate control adjustment member 315 includes a control rod 3151 and an adjustment component 3153. The control rod 3151 penetrates the flow hole 313H, and the diameter of the control rod 3151 gradually decreases from the top to the bottom. Adjustment component 3153 is coupled to the top of control rod 3151. The casing 37 covers the buffer portion 31, the partial rotation component member 33, and the flow rate control connecting member 313, and restricts the buffer solution in the casing 37.

  In the embodiment of the present invention, when the rotating component 33 is rotated and the buffer portion 31 is pushed to cause displacement and the volume of the variable storage portion C changes, the buffer solution is supplied to the variable storage portion C and the casing. It is made to flow between the other spaces in 37 and has a buffering effect. Further, since the diameter of the control rod 3151 gradually decreases from the top to the bottom, the user adjusts the depth penetrating the flow hole 313H of the control rod 3151 so that the hydraulic shock absorber 30 can be adjusted. The degree of buffering provided can be determined and details are described below.

  In one embodiment, the peripheral edge of the top end 310 of the buffer portion 31 is adjacent to the rotating component 33, and the buffer portion 31 includes a first O-ring 31R. The first O-ring 31R is provided between the peripheral edge of the top end 310 and the rotating component 33, and the buffer solution flows into the peripheral edge of the top end 310 of the buffer portion 31 or the variable storage portion C or the variable storage portion. Prevent outflow from C.

  In the embodiment of the present invention, the flow rate control connecting member 313 provides a path through which the buffer solution flows between the buffer portion 31 and the variable storage portion C. In some embodiments, the flow rate control coupling member 313 includes a second O-ring 313R, and the second O-ring 313R is provided between the flow rate control coupling member 313 and the top surface of the buffer portion 31.

  For example, when the hydraulic shock absorber 30 of the present invention is applied to the hinge structure of the door body, the door body is gradually opened from the closed state, that is, the rotating component 33 is rotated and the shock absorber 31 is moved. When a downward displacement occurs in the longitudinal direction parallel to the hydraulic shock absorber 30 and the volume of the variable storage portion C gradually increases, the buffer solution flows through the flow holes 313H of the flow rate control connecting member 313 and The flow rate control connecting member 313 and the through hole 31H can flow into the variable accommodation portion C via a gap.

  On the contrary, the door body is gradually closed from the open state, that is, the rotating component 33 is rotated and the shock absorber 31 is pushed to cause an upward displacement in the longitudinal direction parallel to the hydraulic shock absorber 30, thereby allowing variable accommodation. When the volume of the portion C is gradually reduced, the hydraulic pressure and the buffer solution received by the flow rate control connecting member 313 flow into the buffer portion 31 via the gap between the flow rate control connecting member 313 and the through hole 31H. This can be prevented by the second O-ring 313R, but can flow into the buffer portion 31 via the flow hole 313H of the flow rate control connecting member 313. Such a design makes it possible to obtain a larger buffer when the door body is gradually closed from the open state than when the door body is gradually opened from the closed state. It is possible to effectively prevent problems such as unpleasant noise caused by intense collisions and damage.

  In the embodiment of the present invention, a screw portion 3155 is provided around the adjustment component 3153 and a slot 3157 is provided at the top end of the adjustment component 3153, and the adjustment component 3153 is rotated through the screw portion 3155. The top end 330 can be screwed. The slot 3157 and the threaded portion 3155 are used to adjust the depth at which the control rod 3151 penetrates the flow hole 313H.

  Since the diameter of the control rod 3151 gradually decreases from the top to the bottom, the greater the depth of penetration of the control rod 3151 into the flow hole 313H, the greater the buffer solution can pass through the flow hole 313H. The area is reduced and the buffer flow rate is decreased. Conversely, the shallower the depth through which the control rod 3151 extends through the flow hole 313H, the larger the cross-sectional area through which the buffer solution can pass through the flow hole 313H, and the buffer flow rate is increased. That is, the user can determine the degree of buffering provided by the hydraulic shock absorber 30 by adjusting the depth of the control rod 3151 penetrating through the flow hole 313H.

  For example, if the degree of buffering is too large, the user turns the slot 3157 in the counterclockwise direction with a tool to reduce the depth at which the control rod 3151 penetrates the flow hole 313H, that is, the buffer solution. However, the cross-sectional area that can pass through the flow holes 313H increases, and the buffer flow rate is increased to reduce the degree of buffering. Conversely, if the degree of buffering is too small, the user turns the slot 3157 clockwise with a tool to increase the depth at which the control rod 3151 penetrates the flow hole 313H, that is, the buffer solution flows into the flow hole 313H. The cross-sectional area that can pass through is reduced, and the buffering rate is increased by slowing the flow rate of the buffer solution.

  In one embodiment, the adjustment component 3153 further includes at least one third O-ring 315R, which prevents the buffer from flowing out of the periphery of the adjustment component 3153. Used for.

  As shown in FIGS. 1 and 2, in one embodiment, the buffer portion 31 includes two spiral grooves 311, and the spiral grooves 311 are parallel to each other and provided on the side wall of the buffer portion 31. The rotating component 33 includes an actuating lever 331, and the actuating lever 331 displays two through-holes 333 on the side wall of the rotating component 33 (FIG. 1 shows only one of the through-holes 333). ) And fixed, and the operating lever 331 penetrates the spiral groove 311 so that the rotating component 33 can be pivotally connected to the buffer portion 31.

  When the rotating component 33 is rotated, the operating lever 331 can be moved along the spiral groove 311. Since the operating lever 331 moves along the spiral groove 311, the buffer portion 31 is displaced with respect to the rotating component 33 in the longitudinal direction parallel to the hydraulic shock absorber 30, and the volume of the variable storage portion C is increased. Change.

  FIG. 3 is a partially exploded perspective view when the above-described hydraulic shock absorber 30 is applied to the hydraulic shock absorber structure 100. As shown in FIG. 3, the hydraulic buffer hinge structure 100 includes a first hinge piece 10, a second hinge piece 20, and a hydraulic shock absorber 30. The first hinge piece 10 includes the first sleeve 11, and the second hinge piece 20 includes the second sleeve 21.

Therefore, when the first sleeve 11 and the second sleeve 21 rotate relative to each other, the rotating component 33 is rotated and the buffer portion 31 is pushed to cause a displacement. The volume is changed, and the buffer solution is caused to flow between the variable storage portion C and the other space in the housing 37. A buffering effect can be provided through the flow of the buffer solution between the variable storage portion C and the other spaces in the housing 37.

  As shown in FIG. 3, in one embodiment, the first sleeve 11 includes a cap 111, the cap 111 includes an adjustment hole 111H, and the adjustment hole 111H is an adjustment component 3153 shown in FIGS. And the slot 3157 is exposed, and the area of the adjustment hole 111H is smaller than the area of the top surface of the adjustment component 3153. That is, the user does not need to open the cap 111 of the first sleeve 11, and can adjust the depth of penetration of the tool such as a driver through the adjustment hole 111 </ b> H into the flow hole 313 </ b> H of the control rod 3151. Further, since the area of the adjustment hole 111H is smaller than the area of the top surface of the adjustment component 3153, the flow rate control adjustment member 315 is detached from the rotation component 33 by stopping the flow rate control adjustment member 315 through the cap 111. Can be completely prevented.

  As shown in FIG. 3, in one embodiment, the hydraulic shock-absorbing hinge structure 100 further includes an operating ring 41 and a retainer ring 43. The operating ring 41 is fitted to the top end 301 of the hydraulic shock absorber 30 (that is, the top end 330 of the rotating component 33), and the retainer ring 43 is fitted to the bottom end 303 of the hydraulic shock absorber 30. The top end 301 of the hydraulic shock absorber 30 (that is, the top end 330 of the rotating component 33) is connected to the first sleeve 11 through the operating ring 41, and the bottom end 303 of the hydraulic shock absorber 30 is connected to the second sleeve 21 through the retainer ring 43. Fixed to.

  When the first sleeve 11 and the second sleeve 21 rotate relative to each other, the rotating component 33 rotates and the operating lever 331 is moved along the spiral groove 311. The top end 301 of the hydraulic shock absorber 30 (that is, the rotating component 33) is restricted by the first sleeve 11, and the bottom end 303 of the hydraulic shock absorber 30 is restricted by the second sleeve 21. A longitudinal displacement parallel to the shock absorber 30 is not caused. In comparison, the actuating lever 331 moves along the spiral groove 311, and the shock absorber 31 is displaced with respect to the rotating component 33 in the longitudinal direction parallel to the hydraulic shock absorber 30. Change the volume of.

  In summary, in the hydraulic shock absorber 30 according to the embodiment of the present invention and the hydraulic shock absorber hinge structure 100 to which the hydraulic shock absorber 30 is applied, the control rod 3151 of the flow rate control adjusting member 315 penetrates the flow hole 313H of the flow rate control connecting member 313. By adjusting the depth to be controlled, the degree of buffering provided by the hydraulic shock absorber 30 is controlled. Therefore, after adding a buffering mechanism to the rotating shaft between the two hinge pieces in the prior art, it is possible to effectively solve the problem caused by the fact that the degree of buffering cannot be adjusted or controlled again.
