Description

Technical Field

[0001] This utility model belongs to the technical field of beverage drinking equipment, specifically relating to a wine spear. Background Technology

[0002] In the field of wine storage and dispensing technology, wine barrels, as a common container, are widely used for holding and transporting alcoholic beverages. Typically, a dispensing spout is fitted at the mouth of the barrel, which works in conjunction with an external dispenser to expel liquid from the barrel under pressure. Existing dispensing spouts generally consist of a valve body, a dispensing pipe, and a base, with the dispensing pipe threadedly connected to the valve body via the base. However, this structure has several drawbacks in practical applications. First, due to the unavoidable vibration and impact during transportation or use, long-term exposure can cause the threaded connection between the base and the valve body to loosen, leading to component detachment, affecting the normal dispensing function of the spout, and reducing the stability and reliability of the system. Second, the assembly of this structure requires sequential tightening of threads, resulting in a complex assembly process, low production efficiency, and difficulties in later maintenance and disassembly. Utility Model Content

[0003] In view of the various shortcomings of the existing technology, a new type of wine spear is proposed to solve the technical problems of unstable connection, easy loosening and complicated assembly in the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A wine spear includes a valve body and a wine outlet pipe. A valve core, a return spring, and a base are sleeved around the wine outlet pipe. The bottom end of the base engages with the outer wall of the wine outlet pipe, and the top end of the base engages with the inner valve wall of the valve body. A bearing surface is provided between the bottom end and the top end of the base. The bottom end of the return spring presses against the bearing surface, and its top end presses against the valve core. Under the action of the return spring, the valve core abuts against the top end of the valve body and the top end of the wine outlet pipe, respectively.

[0005] The technical solution is further configured such that the base includes a first snap-fit ​​portion at its bottom end and a second snap-fit ​​portion at its top end, the diameter of the first snap-fit ​​portion being different from the diameter of the second snap-fit ​​portion, such that the bearing surface is formed at the junction of the two, and the bearing surface is provided with an annular receiving groove for accommodating the return spring.

[0006] The technical solution is further configured such that the outer wall of the wine outlet tube is recessed towards its center to form a diameter reduction section, the bottom end of the diameter reduction section continues to be recessed towards its center to form a groove, and the top end of the diameter reduction section forms a protruding edge where it connects with the outer wall of the wine outlet tube. The bottom end of the first snap-fit ​​portion protrudes towards its center to form a first snap protrusion, which is adapted to the slot, and the top end of the first snap-fit ​​portion abuts against the protruding edge.

[0007] The technical solution is further configured such that the first snap-fit ​​part is provided with a slit extending along its axial direction, providing space for the expansion and deformation that occurs during the process of it being fitted around the wine outlet tube.

[0008] The technical solution is further configured such that multiple air inlets are arranged along the circumference of the bearing surface, and a support block is arranged between adjacent air inlets. The support block is provided with a groove, and the grooves on the multiple support blocks form an annular receiving groove.

[0009] The technical solution is further configured such that a bayonet is provided on the inner valve wall of the valve body, and a second latching protrusion adapted to the bayonet is provided on the outer wall of the second latching part, and the top of the second latching part is located higher than the top of the bayonet.

[0010] The technical solution is further configured such that a sealing groove is provided circumferentially on the outer wall of the wine outlet pipe and below the wine outlet, and a sealing ring is disposed in the sealing groove. The outer ring of the sealing ring protrudes from the opening of the sealing groove and abuts against the inner wall of the valve core, thereby ensuring the sealing performance between the wine outlet pipe and the valve core.

[0011] The technical solution is further configured such that the valve core includes an end cap and a connecting part. The surface of the end cap is provided with a first abutting groove that abuts against the top end of the wine outlet pipe and a second abutting groove that abuts against the top end of the valve body. The connecting part is sleeved around the wine outlet pipe and extends to the bottom of the sealing groove.

[0012] The technical solution is further configured such that a first ring-shaped abutment protrusion is provided in the first abutment groove along its circumference, and an annular groove adapted to the first abutment protrusion is provided at the top of the wine outlet tube.

[0013] The technical solution is further configured such that a second abutting protrusion is provided on the outer edge of the end cap portion, which abuts against the inner valve wall of the valve body.

[0014] The beneficial effects of this utility model are: By engaging the base with the dispensing pipe and valve body respectively, a bidirectional limiting snap-fit ​​structure is formed, replacing the traditional threaded connection. This structure is less prone to relative rotation or axial displacement when subjected to vibration or impact, effectively preventing loosening of connections or even component detachment caused by shaking during transportation or use, significantly improving the overall structural stability and sealing reliability of the wine spear. Simultaneously, the elimination of thread tightening operations reduces assembly steps and tool reliance, enabling rapid installation and disassembly, which is beneficial for automated production and subsequent maintenance, and reduces manufacturing costs.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] According to an embodiment of this utility model, a wine spear is provided; please refer to [link / reference]. Figures 1 to 5 The system includes a valve body 100 and a wine outlet pipe 200. The wine outlet pipe 200 is surrounded by a valve core 300, a return spring 500, and a base 400. The bottom end of the base 400 engages with the outer wall of the wine outlet pipe 200, and the top end of the base 400 engages with the inner valve wall 101 of the valve body 100. A bearing surface 403 is provided between the bottom end and the top end of the base 400. The bottom end of the return spring 500 presses against the bearing surface 403, and its top end presses against the valve core 300. Under the action of the return spring 500, the valve core 300 abuts against the top end of the valve body 100 and the top end of the wine outlet pipe 200, respectively.

[0020] By adopting the above technical solution, the base 400 is engaged with the dispensing pipe 200 and the valve body 100 respectively, forming a bidirectional limiting snap-fit ​​structure, replacing the traditional threaded connection. This structure is less prone to relative rotation or axial displacement when subjected to vibration or impact, effectively avoiding loosening of connections or even component detachment caused by shaking during transportation or use, significantly improving the overall structural stability and sealing reliability of the wine spear. Simultaneously, the elimination of thread tightening operations reduces assembly steps and tool dependence, enabling rapid installation and disassembly, which is beneficial for automated production and subsequent maintenance, and reduces manufacturing costs. Furthermore, a bearing surface 403 is provided to provide stable support for the return spring 500. The two ends of the return spring 500 press against the bearing surface 403 and the valve core 300 respectively. Under the action of pre-tightening force, the valve core 300 is simultaneously tightly abutted against the top of the valve body 100 and the top of the dispensing pipe 200, ensuring that the valve core 300 remains stably closed when not in operation, preventing leakage.

[0021] In one embodiment of the wine spear, please refer to Figures 1 to 7The base 400 includes a first snap-fit ​​portion 401 at its bottom end and a second snap-fit ​​portion 402 at its top end. The diameter of the first snap-fit ​​portion 401 is different from the diameter of the second snap-fit ​​portion 402, so that the bearing surface 403 is formed at the junction of the two. The bearing surface 403 is provided with an annular receiving groove 405 for accommodating the return spring 500.

[0022] By adopting the above technical solution, the base 400 is integrally formed, and its first snap-fit ​​part 401 and second snap-fit ​​part 402 have different diameters to form a bearing surface 403. An annular receiving groove 405 is provided on this surface to accurately position and stably accommodate the return spring 500, prevent the return spring 500 from shifting or tilting, and further improve the stability of the rebound performance.

[0023] In one embodiment of the wine spear, please refer to Figures 1 to 8 The outer wall of the wine outlet tube 200 is recessed towards its center to form a diameter reduction section 203. The bottom end of the diameter reduction section 203 continues to be recessed towards its center to form a groove 204. The top end of the diameter reduction section 203 forms a protruding edge 205 where it meets the outer wall of the wine outlet tube. The bottom end of the first snap-fit ​​portion 401 protrudes towards its center to form a first snap-fit ​​protrusion 406, which is adapted to the snap-fit ​​groove 204, and the top end of the first snap-fit ​​portion 401 abuts against the protruding edge 205.

[0024] Furthermore, the inner diameter of the first snap-fit ​​portion 401 is adapted to the outer diameter of the diameter reduction section 203.

[0025] During assembly, the base 400 is inserted into the bottom end of the wine outlet tube 200 and moved upward until the first locking protrusion 406 is embedded in the locking groove 204, and the top end of the first locking part 401 abuts against the protruding edge 205 to form an axial stop, preventing the base 400 from being over-inserted or dislodged, and enhancing the connection firmness.

[0026] In one embodiment of the wine spear, please refer to Figures 1 to 8 The first snap-fit ​​part 401 is provided with a slit extending along its axial direction to provide space for the expansion and deformation that occurs during the process of it being fitted around the wine outlet tube 200.

[0027] Understandably, the first protrusion 406 and the slot 204 are interference fit, and the axial gap has a certain elastic expansion capacity. During the assembly process, it can be smoothly fitted onto the wine outlet tube 200. The elasticity of the material is used to achieve quick snap-fit, taking into account both assembly convenience and connection strength, and providing reliable mechanical locking.

[0028] In one embodiment of the wine spear, please refer to Figures 1 to 7The bearing surface 403 is provided with multiple air inlets 407 along its circumference, allowing external gases (such as CO2 or nitrogen) to enter the barrel to push the wine out and meet the pressure supply requirements.

[0029] Meanwhile, a support block 404 is provided between adjacent air inlets 407. The support block 404 is provided with grooves, and the grooves on multiple support blocks 404 form an annular receiving groove 405. It can be understood that the air inlets 407 are spaced apart by the support blocks 404, which not only ensures the gas flow channel, but also forms an annular receiving groove 405 through the grooves on the support blocks 404, realizing the integration of structure and function, and taking into account both the air intake and the support function of the return spring 500.

[0030] Optionally, the support block 404 extends from the top of the first latching portion 401, across the bearing surface 403, and to the bottom of the second latching portion 402. It is understood that the support block 404, acting as a reinforcing rib structure penetrating the critical stress area of ​​the base 400, significantly improves the structural stability of the base 400 under radial and axial loads, preventing twisting, cracking, or plastic deformation due to external forces during assembly or use. Simultaneously, the return spring 500 applies periodic pressure to the bearing surface 403 during compression and rebound. The support block 404 effectively transfers the load from the bearing surface 403 to both ends (first latching portion 401, second latching portion 402), preventing localized stress concentration that could lead to collapse or breakage of the bearing surface 403, and ensuring the reliability and consistency of the return spring 500's operation.

[0031] Optionally, a guide ramp is provided at the top of the groove, which can automatically guide the return spring 500 during installation. Even if the initial position of the return spring 500 is slightly off, it can slide smoothly into the annular receiving groove 405 along the guide ramp, avoiding problems such as misalignment, jamming, or incomplete insertion of the return spring 500.

[0032] In one embodiment of the wine spear, please refer to Figures 1 to 12 The inner valve wall 101 of the valve body is provided with a bayonet 102, and the outer wall of the second locking part 402 is provided with a second locking protrusion 408 adapted to the bayonet 102. The inner valve wall 101 is provided with an axially extending gap to provide space for elastic deformation. During assembly, the base 400 is pressed into the valve body 100 axially, and the second locking protrusion 408 pushes the inner valve wall 101 to expand and pass over the bayonet 102. Subsequently, the valve body 100 elastically resets, causing the second locking protrusion 408 to engage with the bayonet 102, achieving quick locking. At the same time, the top of the second locking part 402 is higher than the top of the bayonet 102 and lower than the top of the gap, so that the second locking protrusion 408 is effectively limited by the bayonet 102, preventing the base 400 from accidentally coming off during use.

[0033] Optionally, the outer diameter of the second snap-fit ​​portion 402 is adapted to the inner diameter of the inner valve wall 101, that is, the second snap-fit ​​portion 402 is engaged inside the inner valve wall 101. At the same time, a limit block 409 is provided on the outer wall of the second snap-fit ​​portion 402 for abutting against the bottom end of the inner valve wall 101.

[0034] Optionally, the inner valve wall 101 extends axially from the top of the valve body 100, and an outer valve wall 104 surrounds the inner valve wall 101, with a gap between them. The inner surface of the outer valve wall 104 is provided with an internal thread adapted to the barrel, and the outer surface of the outer valve wall 104 is provided with an external thread adapted to the barrel holder 900. There is also an inner edge 103 between the inner valve wall 101 and the outer valve wall 104, and a sealing ring for sealing with the barrel is fitted on the inner edge 103.

[0035] In one embodiment of the wine spear, please refer to Figures 1 to 8 A sealing groove 202 is provided circumferentially on the outer wall of the wine outlet pipe 200 and below the wine outlet 201. A sealing ring 600 is disposed in the sealing groove 202. The outer ring of the sealing ring 600 protrudes from the opening of the sealing groove 202 and abuts against the inner wall of the valve core 300, thereby ensuring the sealing performance between the wine outlet pipe 200 and the valve core 300.

[0036] By adopting the above technical solution, the outer ring of the sealing ring 600 protrudes and makes interference contact with the inner wall of the valve core 300, forming a dynamic seal; effectively preventing leakage of wine between the wine outlet pipe 200 and the valve core 300, and maintaining good sealing performance, especially under high-pressure wine supply conditions. The sealing ring 600 is placed in the sealing groove 202 on the outer wall of the wine outlet pipe 200, rather than on the inner wall of the valve core 300. This design fixes the sealing ring 600 to a stationary component, avoiding the problem of the sealing ring 600 falling off or wearing out due to the reciprocating motion of the valve core 300; at the same time, the wine outlet pipe 200 has high rigidity and good surface precision, which is conducive to achieving a uniform and reliable dynamic seal.

[0037] Optional, please refer to Figures 1 to 12 The bottom of the dispensing tube 200 is provided with an anti-detachment protrusion ring 206, and the dispensing tube 700 is sleeved on the anti-detachment protrusion ring 206 and fixed by a buckle 800. The end of the dispensing tube 700 is recessed to form a groove 701, and multiple grooves 701 are provided along the circumference of the dispensing tube 700. During the cleaning process required for inverted filling, the grooves 701 help the cleaning liquid to be evenly distributed to the inner wall of the barrel from multiple directions, thereby improving the cleaning effect.

[0038] In one embodiment of the wine spear, please refer to Figures 1 to 11The valve core 300 includes an end cap portion 301 and a connecting portion 302. The surface of the end cap portion 301 is provided with a first abutting groove 303 that abuts against the top end of the wine outlet pipe 200 and a second abutting groove 304 that abuts against the top end of the valve body 100. The connecting portion 302 is sleeved around the wine outlet pipe 200 and extends to the bottom of the sealing groove 202.

[0039] By adopting the above technical solution, the first abutment groove 303 cooperates with the top of the wine outlet pipe 200 to achieve axial positioning; the second abutment groove 304 cooperates with the top of the valve body 100 to restrict the upward displacement of the valve core 300; the connecting part 302 extends to the bottom of the sealing groove 202 to provide sufficient guiding length, ensuring that the valve core 300 moves smoothly and without deviation, and improving the opening and closing accuracy.

[0040] In one embodiment of the wine spear, please refer to Figures 1 to 4 The first abutment groove 303 has a first abutment protrusion 305 arranged in an annular shape along its circumference, and the top end of the wine outlet pipe 200 has an annular groove adapted to the first abutment protrusion 305. At the same time, the outer edge of the end cap portion 301 has a second abutment protrusion 306 that abuts against the inner valve wall 101 of the valve body.

[0041] By adopting the above technical solution, the first abutting protrusion 305 cooperates with the annular groove to form a circumferential limiting structure, preventing the valve core 300 from rotating relative to the wine outlet pipe 200, ensuring that the sealing ring 600 is evenly pressurized, and avoiding local wear or leakage. At the same time, the second abutting protrusion 306 contacts the inner valve wall 101 of the valve body, forming radial positioning and support, preventing the valve core 300 from tilting or shaking, enhancing the stability of the fit between the valve core 300 and the valve body 100, and improving the smoothness of movement and the overall sealing reliability.

[0042] It should be noted that the second abutment protrusions 306 are arranged in multiple spaced intervals along the circumference of the end cap portion 301, rather than being designed as a continuous ring. During the process of pressing down the valve core 300, external gas enters the barrel through the gap between adjacent second abutment protrusions 306 and the air inlet 407, pushing the liquid out of the outlet 201.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.
