[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] It should be clear that the described implementations are only part of the implementations of the utility model, not all of the implementations. Based on the implementations in the utility model, all other implementations obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0020] The embodiment of the utility model provides a hinge for a cone valve type filling pump and a cone valve type filling pump, which can reduce the production cost of the hinge.

[0021] The following combination Figure 1 and Figure 2 , the implementation mode of the utility model is further explained.

[0022] Figure 1 The structure diagram of an embodiment of the hinge of the utility model for a cone valve filling pump is shown. Figure 1 As shown, the hinge for the cone valve type filling pump of this embodiment may include a first connecting plate 1 , a second connecting plate 2 and a connecting pin 3 .

[0023] Among them, the first connecting plate 1 can also be called a left half hinge, the second connecting plate 2 can also be called a right half hinge, and the connecting pin shaft 3 can also be called a transfer shaft, a rotating shaft or a hinge shaft, etc.

[0024] In one embodiment, a first connecting sleeve 6 is provided on one side of the first connecting plate 1 close to the second connecting plate 2, a second connecting sleeve 7 is provided on one side of the second connecting plate 2 close to the first connecting plate 1, and the connecting pin 3 is rotatably connected to the first connecting sleeve 6 and the second connecting sleeve 7, respectively, wherein the connecting pin 3 can be inserted into the first connecting sleeve 6 and the second connecting sleeve 7, and the connecting pin 3 can be respectively clearance-matched with the first connecting sleeve 6 and the second connecting sleeve 7. In this way, during the use of the hinge, the hinge can allow two solid bodies respectively connected to the first connecting plate 1 and the second connecting plate 2 to rotate relative to each other.

[0025] See also Figure 2 As shown, in one embodiment, the connecting pin shaft 3 is provided with an oil chamber 301 in the axial direction, and the side of the connecting pin shaft 3 is provided with at least two oil supply grooves 302, the at least two oil supply grooves 302 are respectively connected to the oil chamber 301, and the openings of the at least two oil supply grooves 302 are respectively provided on the outer side wall of the connecting pin shaft 3. The oil chamber 301 can be used to store lubricating oil, and when lubricating oil is placed in the oil chamber 301, the oil supply groove 302 can be used to allow the lubricating oil in the oil chamber 301 to enter between the connecting pin shaft 3 and the first connecting sleeve and the second connecting sleeve.

[0026] The hinge for a cone valve filling pump provided in the embodiment of the utility model can add lubricating oil to the oil chamber 301, so that the lubricating oil flows out from the oil supply groove 302 to the outer wall of the connecting pin 3, thereby lubricating the first connecting sleeve 6 and / or the second connecting sleeve 7 connected to the connecting pin 3, without the need to use a copper sliding bearing between the connecting pin 3 and the first connecting sleeve 6 and the second connecting sleeve 7, thereby reducing the production cost of the hinge.

[0027] To facilitate lubrication of the first connecting sleeve 6 and the second connecting sleeve 7 , in one embodiment, the at least two oil supply grooves 302 may correspond to the first connecting sleeve 6 and the second connecting sleeve 7 , respectively.

[0028] See also Figure 2 As shown, in order to prevent the first connecting sleeve 6 and / or the second connecting sleeve 7 from sliding off the connecting pin 3, in some embodiments, a fastening assembly 4 is provided at the end of the connecting pin 3, and the fastening assembly 4 abuts against the first connecting sleeve 6 and / or the second connecting sleeve 7. In this way, the fastening assembly 4 can limit the movement of the first connecting sleeve 6 and / or the second connecting sleeve 7 in the direction of disengaging from the connecting pin 3 at the end of the connecting pin 3, thereby preventing the first connecting sleeve 6 and / or the second connecting sleeve 7 from sliding off the connecting pin 3.

[0029] The fastening assembly 4 may be provided at one end of the connecting pin 3, or at both ends of the connecting pin 3. If the fastening assembly 4 is provided at one end of the connecting pin 3, a positioning shoulder may be provided at the other end of the connecting pin 3. The fastening assembly 4 may include a locking nut 41 and a washer 42, and the washer 42 may be located between the locking nut 41 and the first connecting sleeve 6 and / or the second connecting sleeve 7.

[0030] In order to facilitate the injection of lubricating oil into the oil chamber 301 of the connecting pin shaft 3, in some embodiments, the end of the oil chamber 301 is provided with an internal thread, and the internal thread is used to install the oil filling cup 8 or the screw plug 5. Exemplarily, when injecting lubricating oil into the oil chamber 301 of the connecting pin shaft 3, the oil filling cup 8 can be threadedly connected to the end of the oil chamber 301. After injecting lubricating oil into the oil chamber 301 of the connecting pin shaft 3, the screw plug 5 can be threadedly connected to the end of the oil chamber 301 to seal the oil chamber 301. Among them, the end of the oil chamber 301 can be one end of the oil chamber 301, or both ends of the oil chamber 301.

[0031] See also Figure 2 As shown, in order to facilitate the uniform distribution of the lubricating oil between the connecting pin 3 and the first connecting sleeve 6 and / or the second connecting sleeve 7, in some embodiments, the oil supply groove 302 is a fan-shaped groove perpendicular to the inner wall of the first connecting sleeve 6 or the second connecting sleeve 7. The fan-shaped groove facilitates the lubricating oil in the oil cavity 301 to flow evenly along the fan-shaped edge to the working area between the connecting pin 3 and the first connecting sleeve 6 and / or the second connecting sleeve 7, forming a uniform oil film on the contact surface, thereby providing a consistent lubrication effect.

[0032] In order to improve the oil supply efficiency of the oil chamber 301 of the connecting pin 3, in one embodiment, the at least two oil supply grooves 302 are arranged in an axially staggered manner. In other words, the openings of the at least two oil supply grooves 302 arranged in the axial direction are in different directions. In this way, the dead zone of the oil in the oil supply area between the connecting pin 3 and the first connecting sleeve 6 and / or the second connecting sleeve 7 can be reduced, ensuring that the oil can flow to the aforementioned oil supply area more effectively. In addition, the at least two oil supply grooves 302 are arranged in an axially staggered manner, which can make the flow path of the lubricating oil more reasonable, and help the oil to effectively lubricate the working area between the connecting pin 3 and the first connecting sleeve 6 and / or the second connecting sleeve 7.

[0033] In one embodiment, the central angle of the arc-shaped opening of the oil supply groove 302 is 120 degrees to 180 degrees. In one embodiment, the central angle of the arc-shaped opening of the oil supply groove 302 is 120 degrees, in another embodiment, the central angle of the arc-shaped opening of the oil supply groove 302 is 150 degrees, and in yet another embodiment, the central angle of the arc-shaped opening of the oil supply groove 302 is 180 degrees.

[0034] See also Figure 2As shown, in order to improve the stress stability of the hinge, in some embodiments, the first connecting sleeve 6 and the second connecting sleeve 7 are coaxially arranged, and the end of the first connecting sleeve 6 corresponds to the end of the second connecting sleeve 7. In this way, the axis of the first connecting sleeve 6 coincides with the axis of the second connecting sleeve 7. Such an alignment can reduce the risk of distortion or deformation of the hinge due to eccentric stress when the hinge is stressed, thereby ensuring stability when subjected to stress. In addition, the axis of the first connecting sleeve 6 coincides with the axis of the second connecting sleeve 7, which can facilitate determination of whether the installation adjustment of the hinge meets the preset requirements, and can facilitate installation of the hinge.

[0035] See also Figure 1 As shown, in some embodiments, the first connecting sleeve 6 includes a first connecting sub-tube 61 and a second connecting sub-tube 62, the first connecting sub-tube 61 and the second connecting sub-tube 62 are respectively arranged at the two ends of the first connecting plate 1 on the side close to the second connecting plate 2, and the second connecting sleeve 7 is arranged in the middle part of the second connecting plate 2 on the side close to the first connecting plate 1; the end of the first connecting sub-tube 61 corresponds to the first end of the second connecting sleeve 7, and the end of the second connecting sub-tube 62 corresponds to the second end of the second connecting sleeve 7. In this way, by arranging the first connecting sleeve 6 of the first connecting plate 1 at both ends and the second connecting sleeve 7 of the second connecting plate 2 in the middle part, the hinge can have better balance when opening and closing, and at the same time, the second connecting sleeve 7 located in the middle part can be stressed as a whole, reducing the risk of stress concentration when stressed.

[0036] See also Figure 1 As shown, in order to facilitate the assembly and disassembly between the first connecting plate 1 and the first connecting sleeve 6 , in one embodiment, the first connecting plate 1 may include a first claw 101 , and the first connecting sleeve 6 may be clamped in the first claw 101 .

[0037] To facilitate assembly and disassembly between the second connecting plate 2 and the second connecting sleeve 7 , in another embodiment, the second connecting plate 2 may include at least two second claws 201 , and the second connecting sleeve 7 may be clamped in the second claws 201 .

[0038] See also Figure 1 As shown, in order to facilitate the installation of the first connecting plate 1 on the object to be hinged, in one embodiment, a plurality of first connecting holes 102 are provided on the first connecting plate 1, a first number of first connecting holes 102 are respectively provided between the first claws 101 and the ends of the first connecting plate 1, and a second number of first connecting holes 102 are provided between the first claws 101, and the first number is smaller than the second number.

[0039] To facilitate the installation of the second connecting plate 2 on the object to be hinged, in another embodiment, a plurality of second connecting holes 202 are provided on the second connecting plate 2; a third number of second connecting holes 202 are respectively provided between the second claws 201 and the ends of the second joint, and a fourth number of second connecting holes 202 are provided between the second claws 201, and the third number is greater than the fourth number.

[0040] The first connection hole 102 and the second connection hole 202 may be arranged opposite to each other.

[0041] See also Figure 2 As shown, the stress points are more susceptible to wear. To reduce the risk of wear at the stress points, in some embodiments, the at least two oil supply grooves 302 correspond to the first claw 101 and the second claw 201 respectively.

[0042] See also Figure 2 As shown, during the installation of the hinge or the opening and closing of the hinge, the connecting pin 3 extends out of both ends of the first connecting plate 1 or the second connecting plate 2, which may affect the operation of the operator. To solve this problem, in some embodiments, the length of the connecting pin 3 is less than the length of the first connecting plate 1 or the second connecting plate 2. This can enhance the compactness of the hinge and reduce the space occupied by the hinge in the closed state.

[0043] The utility model provides a cone valve type filling pump, including a suction valve, a pressure valve and a hinge, wherein the hinge is the hinge described in any of the aforementioned embodiments; the first connecting plate 1 of the hinge is fixedly connected to the suction valve, and the second connecting plate 2 is fixedly connected to the pressure valve.

[0044] The cone valve filling pump provided in the embodiment of the utility model can add lubricating oil to the oil chamber 301 of the hinge, so that the lubricating oil flows out from the oil supply groove 302 to the outer wall of the connecting pin 3, thereby lubricating the first connecting sleeve 6 and / or the second connecting sleeve 7 connected to the connecting pin 3, without the need to use copper sliding bearings between the connecting pin 3 and the first connecting sleeve 6 and the second connecting sleeve 7, thereby reducing the production cost of the hinge.
