Description
Technical Field
[0001] This utility model belongs to the technical field of beverage drinking equipment, and relates to a manual drive structure for a tap. Background Technology
[0002] Drinking beer from kegs generally requires a tap. There are various types of taps on the market, with manual taps being one of the most commonly used. A specific example is a tap and its connection structure disclosed in Chinese Patent (Authorization Announcement No.: CN105090586B), which includes a valve body and a connecting pipe. The connecting pipe has threads, and the valve body has a connecting end that connects to the connecting pipe. The valve body and the connecting pipe are fixed together by a connecting cap. The inner surface of the connecting end has an internal toothed ring, and the connecting pipe has an external toothed ring that meshes with the internal toothed ring. A sealing ring is provided between the connecting end of the valve body and the connecting pipe.
[0003] Combined with the appendix of this comparison document Figure 3 It is understood that the use of this faucet is specifically achieved by the user pushing or pulling the handle, which causes the valve core inside the valve head to slide, thereby opening or closing the wine circuit.
[0004] However, in actual use, users often accidentally touch the handle while wiping and cleaning the barrel and its surrounding area, causing the handle to slide and open the wine passage. This results in the wine flowing out of the barrel through the outlet pipe, causing unnecessary waste of the wine and increasing the cleaning workload. Summary of the Invention
[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a manual drive structure for the faucet. The technical problem to be solved by this utility model is: how to prevent the wine circuit from being accidentally opened.
[0006] The objective of this utility model can be achieved through the following technical solution: A manual drive structure for a faucet, the faucet including a body, a handle, a valve core slidably connected to the body, and a valve stem rotatably connected to the body and capable of driving the valve core to slide. The manual drive structure includes a hand drive rod and a clutch rod arranged opposite each other along the axial direction. The hand drive rod and the clutch rod are both rotatably connected to the body, and the clutch rod can slide along the axial direction. The inner end of the clutch rod passes through the valve stem and is circumferentially positioned with the valve stem. The outer end of the clutch rod extends out of the body, and a safety wrench is hinged to the outer end of the clutch rod and abuts against the outer wall of the body. The outer end of the hand drive rod extends out of the body and is fixedly connected to the handle. A positioning groove is provided at the inner end of the hand drive rod. The safety wrench can rotate around the hinge and drive the clutch rod to slide so that the inner end of the clutch rod is engaged and circumferentially positioned in the positioning groove or disengaged from the positioning groove.
[0007] The manual drive structure of the faucet disclosed in this application is used by the user pulling the handle, which drives the hand drive rod to rotate. In this state, the rotating hand drive rod drives the clutch rod to rotate synchronously, and the rotation of the clutch rod drives the valve stem to swing within the body. The valve stem then drives the valve core to slide within the body, thereby opening the wine passage. After the wine is drawn, pulling the handle in the opposite direction causes the components to move in the opposite direction, thus closing the wine passage. To prevent accidental opening of the wine passage due to accidental handle contact, this application uses a sliding connection to mount the clutch rod within the body, with a safety wrench hinged to its outer end. When wine is drawn, the clutch rod slides inward, causing its inner end to engage with a positioning groove on the inner end of the hand drive rod, thus securing the clutch rod to the hand drive rod. The two drive rods are circumferentially positioned. In this state, the safety wrench is held in place by its hinged end against the outer wall of the main body. At this time, the clutch rod, valve stem, hand drive rod, and wrench are in a linked state, and the user can draw wine normally through the aforementioned operation method. When the user pulls the safety wrench to make the clutch rod slide outward and the inner end disengage from the positioning groove, and at the same time rotates the safety wrench so that its side is against the outer wall of the main body, the clutch rod is axially positioned. In this state, the clutch rod and the hand drive rod are in a separated state. No matter how the handle is turned, the hand drive rod will not drive the clutch rod to rotate, and the clutch rod will not drive the valve core to swing. Thus, the wine passage is always in a closed state. Through this structure, the wine passage is locked and closed, preventing the user from accidentally opening the wine passage by touching the handle.
[0008] In the aforementioned manual drive structure of the faucet, the inner end of the clutch lever is polygonal, the positioning groove is a strip-shaped groove, and the valve stem has a mating hole extending through its two side walls along the transverse direction. The inner end of the clutch lever passes through the mating hole, and its outer peripheral wall fits against the inner peripheral wall of the mating hole. This design achieves circumferential positioning between the inner end of the clutch lever, the inner end of the manual drive lever, and the valve stem. This allows the clutch lever to slide laterally without affecting the wine-drawing operation. Furthermore, by making the positioning groove a strip-shaped groove, the fit tolerance between the inner end of the clutch lever and the inner end of the manual drive lever is reduced, preventing potential movement of the clutch lever that could lead to failure in engagement with the manual drive lever.
[0009] In the aforementioned manual drive structure of the faucet, a spring is provided inside the main body, and a stepped surface is formed circumferentially between the two ends of the clutch lever. The spring is sleeved on the clutch lever and acts elastically between the inner wall of the main body and the stepped surface. With this arrangement, when the safety wrench is pulled so that its free end is horizontal, the spring can apply elastic force to the stepped surface of the clutch lever with the inner wall of the main body as a fulcrum. The elastic force of the spring directly drives the clutch lever to slide forward so that its inner end engages with the positioning groove, making operation more convenient.
[0010] In the aforementioned manual drive structure of the faucet, the hinge end of the safety wrench is hemispherical, and the hinge end of the safety wrench has a hinge groove extending through both ends in the radial direction. The outer end of the clutch rod is inserted into the hinge groove and hinged to the hinge end of the safety wrench through a pin. The vertical distance from the hinge point of the clutch rod and the safety wrench to any end of the hinge groove is greater than the vertical distance from the hinge point of the clutch rod and the safety wrench to the end face of the hinge end of the safety wrench. While the safety wrench is hinged, when the operator pulls the safety wrench to slide the clutch lever outward until its inner end disengages from the positioning groove, the operator can turn the safety wrench to rotate it around the hinge. The side wall of the hinge end replaces the end face and the outer wall of the main body to abut against it. Due to the difference in the vertical distance from the hinge point to any end of the hinge groove and the vertical distance from the hinge point to the end face of the safety wrench hinge end, the clutch lever overcomes the elastic force of the spring to maintain axial positioning and prevents it from sliding inward and getting stuck in the positioning groove, thereby achieving the locking and closing of the wine circuit.
[0011] In the aforementioned manual drive structure of the faucet, the outer circumferential surface of the hinge end of the safety wrench has two planar abutment surfaces. The hinge groove extends through both abutment surfaces. When the safety wrench rotates around the hinge so that the free end faces upward or downward, the hinge end of the safety wrench can abut against the outer wall of the main body through one or the other abutment surface. This design ensures the positioning effect of the safety wrench in the closed state of the liquor circuit (i.e., the clutch lever sliding back state), thus ensuring the positioning stability of the clutch lever.
[0012] In the aforementioned manual drive structure of the faucet, the contact surfaces and the hinged end face of the safety wrench form a curved transition. This ensures smooth rotation of the safety wrench around the hinge and avoids excessive wear on the outer wall of the body caused by sharp corners on the safety wrench.
[0013] Compared with existing technologies, the manual drive structure of this faucet has the following advantages: by using a clutch lever that is slidably connected in the body and a safety wrench that is hinged to the outer end of the clutch lever, the clutch lever can be unlocked when its inner end engages with the positioning groove of the inner end of the hand drive lever, and locked when the clutch lever and the hand drive lever separate from their positioning grooves. This prevents accidental activation of the wine path by touching the handle without affecting the wine drawing process. Attached Figure Description

Detailed Implementation
[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] like Figure 1-8 As shown, in the manual drive structure of this faucet, the faucet includes a body 1, a handle 2, and a valve core 3 slidably connected within the body 1. A valve stem 4, rotatably connected to the valve core 3 and capable of driving the valve core 3 to slide and open or close the wine passage, is rotatably connected within the body 1. For details on how the valve stem 4 drives the valve core 3 to slide, please refer to prior art document CN105090586B; further details are omitted in this application. Figure 3 and Figure 4 As shown, the manual drive structure includes a clutch lever 6 and a hand drive lever 5. The clutch lever 6 and the hand drive lever 5 are rotatably connected in the body 1 in the circumferential direction and their inner ends are arranged opposite each other. The clutch lever 6 can slide along the axial direction.
[0025] like Figure 5 and Figure 8 As shown, the upper end of the valve stem 4 has a mating hole 41 that penetrates its two side walls. The mating hole 41 is specifically a square hole. The inner end of the clutch rod 6 is a quadrangular prism and passes through the mating hole 41. The outer peripheral wall of the inner end of the clutch rod 6 is in contact with the inner peripheral wall of the mating hole 41. Figure 3 , Figure 4 as well as Figure 7As shown, the inner end of the hand drive lever 5 is provided with a long strip-shaped positioning groove 51. The positioning groove 51 is directly opposite to the inner end of the clutch lever 6, and the outer end of the hand drive lever 5 extends out of the body 1 and is fixed to the handle 2 by a threaded connection.
[0026] like Figure 3 and Figure 4 As shown, a spring 11 is provided inside the body 1. The outer end of the clutch lever 6 extends out of the body 1 and there is a planar stepped surface 61 between its two ends along the circumference. The spring 11 is sleeved on the clutch lever 6, with one end abutting against the inner wall of the body 1 and the other end abutting against the stepped surface 61. Driven by the elastic force of the spring 11, the clutch lever 6 always has the tendency to move towards the hand drive lever 5. Driven by this elastic force, the inner end of the clutch lever 6 is inserted into the positioning groove 51, so that the two opposite outer walls of the clutch lever 6 and the two opposite side walls of the positioning groove 51 are in contact.
[0027] like Figure 1-6 As shown, the outer end of the clutch lever 6 has an inner hinge hole radially opened. The manual drive structure also includes a safety wrench 7. The safety wrench 7 has a hinge end and a free end. The hinge end of the safety wrench 7 is hemispherical, and the free end is a bar-shaped rod. The hinge end face of the safety wrench 7 has a hinge groove 71 radially opened and penetrates its two side walls. Near the middle of the two side walls of the hinge groove 71, there are outer hinge holes that penetrate to the outer side wall of the hinge end of the safety wrench 7. The outer end of the clutch lever 6 is embedded in the hinge groove 71 and is positioned by a pin that passes through one of the outer hinge holes, the inner hinge hole and the other outer hinge hole in sequence, thereby realizing the hinge connection between the outer ends of the safety wrench 7 and the clutch lever 6. The vertical distance from the hinge point of the clutch lever 6 and the safety wrench 7 to any end of the hinge groove 71 is greater than the vertical distance from the hinge point of the clutch lever 6 and the safety wrench 7 to the end face of the hinge end of the safety wrench 7. There are two planar abutment surfaces 72 on the outer wall of the hinge end of the safety wrench 7. The two abutment surfaces 72 are set at the two ends of the hinge groove 71, and there is an arc transition between each abutment surface 72 and the end face of the hinge end of the safety wrench 7.
[0028] Operating principle: When wine needs to be drawn, with the hinged end of the safety wrench 7 facing the outer wall of the body 1, the inner end of the clutch lever 6 slides towards the hand drive lever 5 under the elastic force of the spring 11. This causes the inner end of the clutch lever 6 to engage in the positioning groove 51, positioning the clutch lever 6 and the hand drive lever 5 circumferentially. The safety wrench 7 then rests against the outer wall of the body 1 through its hinged end face. At this time, the operator pulls the handle 2, which drives the hand drive lever 5 to rotate. The hand drive lever 5 then drives the clutch lever 6 to rotate synchronously. Simultaneously, the clutch lever 6 drives the valve stem 4 to swing, which in turn drives the valve core 3 to slide, opening the wine passage. After wine is drawn, pulling the handle 2 in the opposite direction causes the components to move in the opposite direction, closing the wine passage. In the idle state, the operator can pull the safety wrench. 7. This causes the clutch lever 6 to overcome the elastic force of the spring 11 and retract outward, eventually causing the inner end of the clutch lever 6 to disengage from the positioning groove 51. At the same time, the operator rotates the safety wrench 7 upward or downward, causing the safety wrench 7 to abut against the outer wall of the body 1 through one of its hinged end abutting surfaces 72, thus achieving axial positioning of the clutch lever 6 and preventing the elastic force of the spring 11 from driving the clutch lever 6 to slide inward. In this state, the transmission between the hand drive lever 5 and the clutch lever 6 fails. At this time, no matter how the operator moves the handle 2, the hand drive lever 5 will not drive the clutch lever 6 to rotate, and the valve stem 4, which is circumferentially positioned with the clutch lever 6, will not drive the valve core 3 to slide, thereby achieving locking and closing of the wine circuit and preventing the operator from accidentally touching the handle 2 and causing the wine circuit to open.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0030] Although this document frequently uses terms such as body 1, spring 11, handle 2, valve core 3, valve stem 4, mating hole 41, hand drive lever 5, positioning groove 51, clutch lever 6, stepped surface 61, safety handle 7, hinge groove 71, and abutment surface 72, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
