Description

一種雙向開合液壓緩衝合頁 Two-way opening and closing hydraulic buffer hinge

本發明屬於門窗配件領域,特別是一種雙向開合液壓緩衝合頁。 The invention belongs to the field of door and window accessories, in particular to a bidirectional opening and closing hydraulic buffer hinge.

目前,很多的合頁都具有緩衝功能。其中,現有緩衝大多由第一合頁體、第二合頁體、連接軸、活動塊、彈簧、定位套管、外套管、限位銷構成,在定位套管上會開設有具有限位元功能的限位元導向孔。在組裝時,彈簧套裝於連接軸上,活動塊活動連接在連接軸端部,並使彈簧兩端分別彈性作用在連接軸與活動塊上,然後使活動塊伸入至定位套管中,並使限位銷同時穿置於限位元導向孔與活動塊上,接著使外套管套裝於連接軸、活動塊、彈簧、定位套管上,再接著使外套管兩端分別穿置於第一合頁體、第二合頁體上,並使連接軸端部與第一合頁體相接,還使定位套管與第二合頁體相接。這樣在第一合頁體與第二合頁體轉動相互轉動時,活動塊會相對定位套管轉動,並使限位元銷在限位元導向孔中滑動。由於,彈簧彈性作用在活動塊上,這樣在沒有外力的作用下,通過彈簧的彈簧就會推動限位元銷在限位元導向孔中滑動,然後通過反向力,就可以使連接軸實現轉動,從而就可使第一合頁體與第二合頁體實現相對轉動,進而就可使門實現自動關閉 的效果。在此類緩衝合頁中,單單通過彈簧的彈力使門實現自動關閉,然而,在長時間的使用下,彈簧的彈力極易出現失效的情況,從而會導致合頁的使用壽命降低。且在此類活動轉動過程中,易出現較大的噪音,十分影響人們的生活。雖然,目前出現了帶有液壓油的合頁,但由於現有合頁結構設計的缺陷,使得液壓油在流程過程中易出現亂流擾動的情況,極大地影響了合頁緩衝作用的穩定性,其無法滿足人們的正常使用。 At present, many hinges have a buffer function. Among them, most of the existing buffers are composed of the first hinge body, the second hinge body, the connecting shaft, the movable block, the spring, the positioning sleeve, the outer sleeve, and the limit pin. The positioning sleeve will be provided with a limit element Function limit pilot hole. During assembly, the spring is set on the connecting shaft, the movable block is movably connected to the end of the connecting shaft, and the two ends of the spring are respectively elastically acting on the connecting shaft and the movable block, and then the movable block is extended into the positioning sleeve, and Put the limit pin on the guide hole of the limit element and the movable block at the same time, then fit the outer sleeve on the connecting shaft, the movable block, the spring, and the positioning sleeve, and then put the two ends of the outer sleeve on the first On the hinge body and the second hinge body, the end of the connecting shaft is connected to the first hinge body, and the positioning sleeve is also connected to the second hinge body. In this way, when the first hinge body and the second hinge body rotate and rotate with each other, the movable block rotates relative to the positioning sleeve, and the limit element pin slides in the limit element guide hole. Due to the elasticity of the spring on the movable block, in the absence of external force, the spring through the spring will push the limiter pin to slide in the limiter guide hole, and then through the reverse force, the connecting shaft can be realized Rotating, so that the first hinge body and the second hinge body can rotate relative to each other, and then the door can be automatically closed Effect. In this type of buffer hinge, the door is automatically closed by the elastic force of the spring alone. However, under long-term use, the elastic force of the spring is prone to failure, which will cause the service life of the hinge to be reduced. Moreover, during the rotation of such activities, large noises are likely to occur, which greatly affects people's lives. Although there are currently hinges with hydraulic oil, due to the defects of the existing hinge structure design, hydraulic oil is prone to turbulence and disturbance during the process, which greatly affects the stability of the hinge buffer. It cannot satisfy people's normal use.

本發明的有益效果:在本發明的設計中,由於芯軸管體一端是套裝在第一密封連接件內端端部上的,且第二密封連接件一端是嵌置於芯軸管體另一端中的,其第二密封連接件嵌置於芯軸管體中後,可使芯軸管體內孔構成密封的油腔。而旋轉連接軸一端、活動活塞凸輪、彈簧、限位缸套都是位於該油腔中,這可以對這些結構起到遮蔽保護的作用,且可降低噪音的產生與減少各構件的磨損量,這有助於提高合頁的使用壽命。在活動活塞凸輪活動過程中,可以使活動活塞凸輪與固定凸輪部之間的空間實現擴大或縮小。由於,第一密封連接件上開設有螺紋調節孔、回油孔、進油孔,在組裝完成後,可在該合頁上形成由進油孔、螺紋調節孔、回油孔、導流槽、油腔、導油孔構成的油路循環通道。由於導油孔上設有單向閥,可使油路循環通道只能實現單向流動,這樣在活動活塞凸輪活動過程中,就能推動液壓油沿著油路循環通道單向流動。又由於螺紋調節孔中設有調節螺塞,這樣通過轉動調節螺塞,可以調節進油孔孔口與回油孔孔口之間的螺紋咬合量,當咬合量越大時,液壓油通過的螺紋咬合間隙就越多,其實現的緩衝作用就越大。當咬合量越小,液壓油通過的螺紋咬合間隙就越少,其實現的緩衝作用 就越少。這樣就可以起到調節緩衝作用力多大的目的。由於進油孔孔口與回油孔孔口都位於螺紋調節孔孔壁上,這能使液壓油更加平穩地順著螺紋的咬合間隙流動,能夠有效地避免亂流擾動的情況,有助於提高合頁的緩衝性能,其能夠完全滿足人們的使用需求。同時,還由於限位缸套上開設有呈字母「V」字形狀的限位元導向孔,這樣在彈簧的彈力作用下,使得限位銷只能停留在限位元導向孔中部,這樣合頁可實現雙向開合。在應用時,可使門既能相外開,又能向內開,而且當門扇打開到一定角度後,能將門扇自動定位在一定角度上;例如,當門扇打開到45度角左右時,門扇能自動打開定位到90度角上,或者,當門扇打開到大於90度角後,門扇能自動打開定位到180度角上。反之,而當門扇關閉到一定角度後,能自動關閉上門扇。並且在門扇關閉的過程中,還具有緩衝作用,避免了門扇過重地撞擊在門框上,起到關門靜音的效果。而通過活動活塞凸輪的活動凸輪部與固定凸輪部的配合,可以與限位元導向孔一起起到雙重的限位作用,這有助於提高合頁的可靠性。該雙向開合液壓緩衝合頁的結構設計十分科學合理,有助於提高合頁的可靠性。 Beneficial effect of the present invention: In the design of the present invention, since one end of the mandrel tube body is sleeved on the inner end of the first sealed connector, and one end of the second sealed connector is embedded in the mandrel tube body After the second sealing connector in one end is embedded in the mandrel tube body, the inner hole of the mandrel tube body can form a sealed oil cavity. The one end of the rotating connecting shaft, the movable piston cam, the spring, and the limit cylinder sleeve are all located in the oil cavity, which can play a role in shielding and protecting these structures, and can reduce the generation of noise and reduce the amount of wear of each component. This helps to increase the service life of the hinge. During the activity of the movable piston cam, the space between the movable piston cam and the fixed cam portion can be expanded or reduced. Since the first sealing connector is provided with a screw adjustment hole, an oil return hole and an oil inlet hole, after the assembly is completed, an oil inlet hole, a screw adjustment hole, an oil return hole and a diversion groove can be formed on the hinge , Oil cavity, oil guide hole constitute the oil circulation channel. Because the one-way valve is provided on the oil guide hole, the oil passage circulation channel can only achieve one-way flow, so that during the movement of the movable piston cam, the hydraulic oil can be pushed to flow in one direction along the oil passage circulation channel. Since the adjusting screw plug is provided in the screw adjusting hole, the screw bite amount between the oil inlet hole and the oil return hole hole can be adjusted by turning the adjusting screw plug. When the bite amount is larger, the hydraulic oil passes The more the thread bite clearance, the greater the cushioning effect it achieves. The smaller the bite amount, the less the bite clearance of the thread through which the hydraulic oil passes, and the cushioning effect it achieves The less. In this way, the purpose of adjusting the buffering force can be achieved. Since the oil inlet hole and the oil return hole are located on the wall of the thread adjustment hole, this can make the hydraulic oil flow more smoothly along the nip gap of the thread, which can effectively avoid the situation of turbulent disturbance and help Improve the buffer performance of the hinge, which can fully meet people's needs. At the same time, because the limit cylinder sleeve is provided with a limit element guide hole in the shape of a letter "V", under the action of the elastic force of the spring, the limit pin can only stay in the middle of the limit element guide hole. The page can be opened and closed in both directions. In application, the door can be opened both outward and inward, and when the door leaf is opened to a certain angle, the door leaf can be automatically positioned at a certain angle; for example, when the door leaf is opened to about 45 degrees, The door leaf can be automatically opened and positioned at a 90-degree angle, or, when the door leaf is opened to an angle greater than 90 degrees, the door leaf can be automatically opened and positioned at a 180-degree angle. On the contrary, when the door leaf is closed to a certain angle, it can automatically close the upper door leaf. And in the process of closing the door leaf, it also has a buffering effect, which avoids the door leaf from hitting the door frame excessively, and has the effect of mute closing the door. Through the cooperation of the movable cam part and the fixed cam part of the movable piston cam, it can play a double limiting role together with the limiting element guide hole, which helps to improve the reliability of the hinge. The structural design of the two-way opening and closing hydraulic buffer hinge is very scientific and reasonable, which helps to improve the reliability of the hinge.

The movable piston cam 34 is fitted with one end of the rotating connecting shaft 36, and the spring 37 is fitted between the movable piston cam 34 and the rotating connecting shaft 36 to assemble and constitute the first mandrel element 4.

如圖3所示,該第一芯軸元件4套裝於芯軸管體31的其中一端中,並使第一密封連接件32置於芯軸管體31的其中一端管口處,以對芯軸管體31的其中一端管口形成密封封端作用;該第二密封連接件33與旋轉連接軸36的另一端相連接,並使第二密封連接件33置於嵌置於芯軸管體31的另一端管口處,以對芯軸管體31的另一端管口形成密封封端作用,以此來在芯軸管體31內形成兩端封閉的密封油腔311。 As shown in FIG. 3, the first mandrel element 4 is fitted in one end of the mandrel tube body 31, and the first sealing connector 32 is placed at one end of the mandrel tube body 31 to align the core One end of the shaft tube 31 forms a sealing end; the second sealing connector 33 is connected to the other end of the rotating connecting shaft 36, and the second sealing connector 33 is placed in the mandrel tube body At the other end nozzle of 31, a sealing end effect is formed on the other end nozzle of the mandrel tube body 31, thereby forming a sealed oil cavity 311 with both ends closed in the mandrel tube body 31.

在本發明的設計中,由於芯軸管體31一端是套裝在第一密封連接件32內端端部上的,且第二密封連接件33一端是嵌置於芯軸管體31另一端中的,其第二密封連接件33嵌置於芯軸管體31中後,可使芯軸管體31內孔構成密封的油腔311。而旋轉連接軸36一端、活動活塞凸輪34、彈簧37、限位缸套35都是位於該油腔311中,這可以對這些結構起到遮蔽保護的作用,且可降低噪音的產生與減少各構件的磨損量,這有助於提高合頁的使用壽命。在活動活塞凸輪34活動過程中,可以使活動活塞凸輪34與固定凸輪部323之間的空間實現擴大或縮小。由於,第一密封連接件32上開設有螺紋調節孔321、回油孔301、進油孔302,在組裝完成後,可在該合頁上形成由進油孔302、螺紋調節孔321、回油孔301、導流槽353、油腔311、導油孔342構成的油路循環通道。由於,導油孔342上設有單向閥343,可使油路循環通道只能實現單向流動,這樣在活動活塞凸輪34活動過程中,就能推動液壓油沿著油路循環通道單向流動。由於,螺紋調節孔321中設有調節螺塞322,這樣通過轉動調節螺塞322,可以調節進油孔302孔口與回油孔301孔口之間的螺紋咬合量,當咬合量越大時,液壓油通過的螺紋咬合間隙就越多,其實現的緩衝作用就越大。當咬合量越小,液壓油通過的螺紋咬合間隙就越少,其實現的緩衝作用就越少。這樣就可以起到調節緩衝作用力多大的目的。由於,進油孔302孔口與回油孔301孔口都位於螺紋調節孔321孔壁上,這能使液壓油更加平穩地順著螺紋的咬合間隙流動,能夠有效地避免亂流擾動的情況,有助於提高合頁的緩衝性能,其能夠完全滿足人們的使用需求。同時,由於,限位缸套35上開設有呈字母「V」字形狀的限位元導向孔352,這樣在彈簧37的彈力作用下,使得限位銷38只能停留在限 位元導向孔352中部,這樣合頁可實現雙向開合。在應用時,可使門既能相外開,又能向內開,並能自動關閉,在關閉過程中,還具有緩衝作用。而通過活動活塞凸輪34的活動凸輪部341與固定凸輪部323的配合,可以與限位元導向孔352一起起到雙重的限位作用,這有助於提高合頁的可靠性。該雙向開合液壓緩衝合頁的結構設計十分科學合理,有助於提高合頁的可靠性。 In the design of the present invention, since one end of the mandrel tube body 31 is sleeved on the inner end of the first seal connector 32, and one end of the second seal connector 33 is embedded in the other end of the mandrel tube body 31 After the second sealing connector 33 is embedded in the mandrel tube body 31, the inner hole of the mandrel tube body 31 can form a sealed oil cavity 311. The one end of the rotating connecting shaft 36, the movable piston cam 34, the spring 37, and the limit cylinder sleeve 35 are all located in the oil chamber 311, which can play a role in shielding and protecting these structures, and can reduce the generation of noise and reduce the various The amount of component wear, which helps to increase the service life of the hinge. During the movement of the movable piston cam 34, the space between the movable piston cam 34 and the fixed cam portion 323 can be enlarged or reduced. Since the first sealing connector 32 is provided with a screw adjustment hole 321, an oil return hole 301, and an oil inlet hole 302, after the assembly is completed, an oil inlet hole 302, a screw adjustment hole 321, a return hole can be formed on the hinge The oil passage 301, the flow guide groove 353, the oil chamber 311, and the oil guide hole 342 constitute an oil passage circulation channel. Since the oil guide hole 342 is provided with a one-way valve 343, the oil passage circulation channel can only achieve one-way flow, so that during the activity of the movable piston cam 34, the hydraulic oil can be pushed along the oil passage circulation channel flow. Since the adjusting screw 322 is provided in the screw adjusting hole 321, by turning the adjusting screw 322, the amount of thread bite between the port of the oil inlet 302 and the port of the oil return hole 301 can be adjusted, when the bite amount is larger The more the thread bite clearance through which the hydraulic oil passes, the greater the cushioning effect it achieves. When the bite amount is smaller, the thread bite clearance through which the hydraulic oil passes is smaller, and the less cushioning effect it achieves. In this way, the purpose of adjusting the buffering force can be achieved. Because the inlet hole 302 and the oil return hole 301 are located on the wall of the thread adjustment hole 321, this can make the hydraulic oil flow more smoothly along the nip of the thread, which can effectively avoid the situation of turbulent disturbance , Help to improve the buffering performance of the hinge, which can fully meet people's needs. At the same time, since the limiting cylinder liner 35 is provided with a limiting element guide hole 352 in the shape of a letter "V", under the elastic force of the spring 37, the limiting pin 38 can only stay at the limit The bit guide hole 352 is central, so that the hinge can be opened and closed in two directions. In application, the door can be opened both outwards and inwards, and can be automatically closed. It also has a buffering effect during the closing process. By the cooperation of the movable cam portion 341 and the fixed cam portion 323 of the movable piston cam 34, it can play a dual limiting role together with the limiting element guide hole 352, which helps to improve the reliability of the hinge. The structural design of the two-way opening and closing hydraulic buffer hinge is very scientific and reasonable, which helps to improve the reliability of the hinge.

通過使活動活塞凸輪34上的限位銷38運動軌跡與限位元導向孔352孔型保持一致,可以避免活動活塞凸輪34與固定凸輪部323相對轉動時,限位銷38出現卡滯的情況,這有助於提高整體結構的可靠性。在實際製造過程中,為增強合頁的密封性,可根據需要在一些結構的連接處設置密封圈。 By keeping the movement path of the limit pin 38 on the movable piston cam 34 consistent with the hole pattern of the limit element guide hole 352, it can be avoided that the movable pin cam 34 and the fixed cam portion 323 rotate relative to each other, and the limit pin 38 is stuck. , Which helps to improve the reliability of the overall structure. In the actual manufacturing process, in order to enhance the sealing performance of the hinge, a sealing ring may be provided at the connection of some structures as required.

The structural design is very simple and reliable. Through the design of the adjustment structure of the spring force of this part of the spring, the invention can not only be adjusted by oil pressure To adjust the hinge running strength, and the hinge running strength can also be adjusted by adjusting the tension of the spring 37, which has the function of double adjustment.
