Description

Technical Field

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

[0002] A beer spear is a specialized accessory for beer dispensing systems, typically used in conjunction with a plate dispenser. Its main function is to insert into the valve of a beer keg, mechanically or manually drawing beer from the keg and conveying it to the dispenser. The beer is then dispensed into glasses or containers through the dispenser's tubing and nozzles. The design of the beer spear ensures a tight seal and hygiene during delivery, preventing air ingress and bacterial contamination, thus guaranteeing the beer's quality and taste. Furthermore, the beer spear is easy to install, disassemble, and clean, facilitating routine maintenance. As an indispensable component of beer dispensing systems, the beer spear provides bars, restaurants, and other venues with an efficient, hygienic, and convenient beer dispensing solution.

[0003] CN212356505U discloses a novel plate-type wine spear, characterized by the following: the lower part of a valve body with a hanger is fitted with a three-claw retaining ring on the spear tube; a spear ring is fitted around the outer side of the valve body; a spear tube is located below the valve body; and a spring and a carbon dioxide valve are mounted on the upper outer side of the spear tube. One end of the spring contacts the upper end face of the three-claw retaining ring on the spear tube, and the other end contacts the lower end face of the carbon dioxide valve flange. The upper end face of the inner bore of the carbon dioxide valve and the lower end face of the pipe end flange are in contact and sealed, and the upper end face of the outer circle of the carbon dioxide valve is in contact and sealed with the upper end face of the inner bore of the valve body. Its advantages include overcoming the drawbacks of existing technologies, a reasonable and novel structural design, and the addition of a flow bridge in the groove on the lower plane of the A-type or G-type valve body, which improves the overall quality of the valve body. The addition of an automatic or manual pressure relief valve at the pipe end can prevent excessive pressure inside the barrel from causing danger. Existing beer spears can be directly removed with tools, which could lead to the theft of beer from the barrel and the alteration or adulteration of the beer during the distribution process. Therefore, this technology still has room for improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wine spear in response to the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wine spear, comprising a valve body, a carbon dioxide valve, and a spear tube. The spear tube is surrounded by a retaining ring that engages with the valve body. The carbon dioxide valve is embedded within the valve body and is axially movable within the valve body. A pad is provided at the bottom of the carbon dioxide valve, and a spring is provided between the pad and the retaining ring. The feature is that: a retaining ring is provided at the top of the valve body to engage with a dispenser; a baffle is provided at the top of the retaining ring to rotatably block the top of the valve body; a driving component is provided on one side of the retaining ring; the driving component can drive the baffle to rotate; a movable claw is provided on the spear tube; the driving component is linked to the sliding claw to enable the driving component to drive the movable claw to open / close; the driving component includes a push switch capable of vertical movement.

[0006] Using the above technical solution, the valve body is equipped with a retaining ring that engages with the distributor. Existing distributors on the market use an arc-shaped retaining groove for engagement with the retaining ring, with the retaining ring portion exposed. A drive assembly is located on one side of the retaining ring without affecting the normal engagement of the spear. Simultaneously, a baffle is located on the top of the retaining ring. When the drive assembly pushes a switch to open or close the baffle, a movable claw on the spear tube is linked to the drive assembly. When the drive assembly closes the baffle, the movable claw opens; when the drive assembly opens the baffle, the movable claw closes. The design of the baffle and movable claw greatly enhances the safety of the spear.

[0007] The aforementioned wine spear can be further configured such that: the driving assembly includes a mounting box installed on one side of the snap ring, a driving motor is installed inside the mounting box, the driving motor has a central shaft connected to a baffle, the mounting box is provided with a partition below the driving motor, and a power supply and a driving circuit are provided inside the partition, the power supply, the driving circuit, the push switch and the driving motor are electrically connected.

[0008] Using the above technical solution, a drive motor is installed in the mounting box on one side of the snap ring. The central shaft of the drive motor is connected to the baffle above the snap ring for linkage. At the same time, a power supply, drive circuit and push switch are installed in the partition below the drive motor. The power supply controls the drive motor through the drive circuit to drive the baffle and the movable snap claw for linkage.

[0009] The aforementioned wine spear can be further configured as follows: the driving circuit includes a Zener diode D1 connected in series with a push switch; the Zener diode D1 is connected in series with a resistor R1; the output of the resistor R1 is connected to a transistor Q1; the base of the transistor Q1 is connected to the resistor R1; the emitter of the transistor Q1 is connected in series with a control chip U1; the control chip U1 is connected in series with a drive motor and can control the forward and reverse rotation of the drive motor; a Zener diode D2 is connected in series between the control chip U1 and the push switch; and a rectifier diode is connected in series with the collector of the transistor Q1. Transistor D3; a resistor R4 is connected in parallel between the base and emitter of transistor Q1; a capacitor C2 is connected in series with the resistor R4; a rectifier diode D4 is connected in parallel between the input terminals of Zener diodes D1 and D2; a resistor R2 is also connected in parallel between the output terminals of Zener diodes D1 and D2; a rectifier diode D5 is connected in parallel between the input terminals of the drive switch; a resistor R3 is connected in series between the drive switch and the power supply; a resistor R5 is connected in series between the control chip U1 and the drive motor; and a Zener diode D6 is connected in parallel between the control chip U1 and the resistor R5.

[0010] By adopting the above technical solution, the switch is connected to the power supply and the voltage is stabilized by a series Zener diode D1, ensuring the stability and reliability of the entire circuit. Resistor R1 acts as a current limiting element, protecting the subsequent circuit from excessive current. Transistor Q1 acts as a switching element, with resistor R4 and capacitor C2 connected in parallel between its base and emitter, forming a low-pass filter, which optimizes the circuit's response speed and stability. Control chip U1 is connected in series with the drive motor and is current-limited by a series resistor R5, ensuring the safe operation of the drive motor. Rectifier diodes D3 and D4 are used for rectification and protection, respectively, ensuring the correct and stable current direction in the circuit. In addition, resistors R2 and R3 act as voltage divider elements, providing a stable operating voltage for the circuit. Different positions of the switch can control the forward and reverse rotation of the drive motor.

[0011] The aforementioned wine spear can be further configured such that: the movable claw includes a mounting ring sleeved on the spear tube, a plurality of first claw arms are hinged on the mounting ring, a second claw arm is hinged to the other end of the first claw arm, a claw is hinged to the other end of the second claw arm, a first contraction spring is installed between the first claw arm and the spear tube, and a second contraction spring is installed between the second claw arm and the first claw arm, the first contraction spring and the second contraction spring can cause the first claw arm and the second claw arm to be in a contracted state under normal conditions, and the second claw arm is linked to the drive motor.

[0012] The above technical solution is adopted. The hinged arrangement between the first claw arm, the second claw arm and the chuck allows for a certain amount of movement space and range of motion between the claw arms. At the same time, the first and second retraction springs can retract the first and second claw arms when the baffle is opened, without affecting the normal extraction and use of the spear. The second claw arm is linked to the drive motor. When the drive motor is working, it can lift the second claw arm. When the second claw arm is lifted, it can drive the first claw arm to lift, causing the movable chuck to open.

[0013] The aforementioned wine spear can be further configured such that: a connecting hole is provided on the second claw arm; an upper collar and a lower collar are sleeved on the central shaft above the drive motor; a connecting groove is formed between the upper collar and the lower collar; the connecting hole and the connecting groove are connected by a connecting line; and when the central shaft rotates, it can drive the connecting line to drive the first claw arm and the second claw arm to open.

[0014] Using the above technical solution, the second claw arm is provided with a connecting hole, and the upper and lower collars on the central shaft of the drive motor form a connecting groove. The connecting hole and the connecting groove on the second claw arm are connected to a connecting wire. The connecting wire is connected to the connecting groove through the cavity part of the valve body. When the drive motor starts to work, the drive motor pulls the connecting wire to lift the second claw arm and performs linkage. When the drive motor reverses, the connecting wire is also reset at the same time. The first claw arm and the second claw arm are reset by the first contraction spring and the second spring.

[0015] The aforementioned wine spear can be further configured such that: the spear tube includes an outer tube and an inner tube disposed inside the outer tube, the center of the inner tube is a flow channel, the outer tube is a solid tube, and the outer wall of the outer tube is provided with an installation groove for mounting a mounting ring and a movable claw.

[0016] Using the above technical solution, an installation groove is provided on the surface of the outer tube. Since the outer tube is a solid tube and a flow channel is provided in the center of the inner tube, the embedded groove for the movable claw and the installation ring to be installed will not affect the normal use of the inner tube. At the same time, the setting of the embedded groove greatly reduces the overall volume after the movable claw is installed.

[0017] The beneficial effects of this utility model are as follows: A baffle is provided at the top of the retaining ring. When the drive component is activated by pushing the switch, the baffle can be opened or closed. At the same time, the movable claw provided on the spear tube is linked to the drive component. When the drive component drives the baffle to close, the movable claw opens; when the drive component drives the baffle to open, the movable claw closes. The baffle and movable claw configuration can greatly enhance the safety of the spear. Attached Figure Description

[0026] Structural parts

[0027] Example 1: As Figure 1-3The present invention provides the following technical solution: a wine spear, comprising a valve body 1, a carbon dioxide valve 2, and a spear tube 3. A retaining ring 4 is arranged around the spear tube 3 to engage with the valve body 1. The carbon dioxide valve 2 is embedded within the valve body 1 and can move axially within the valve body 1. A pad 5 is provided at the bottom of the carbon dioxide valve 2, and a spring 23 is provided between the pad 5 and the retaining ring 4. A retaining ring 6 is provided at the top of the valve body 1 to engage with a dispenser. A baffle 7, which can rotate and block the top of the valve body 1, is provided on the top of the retaining ring 6. A drive assembly is provided on one side of the retaining ring 6 to drive the baffle 7 to rotate. A movable claw 8 is provided on the spear tube 3. The drive assembly is linked to a sliding claw 19, causing the drive assembly to drive the movable claw 8 to open. The valve body 1 is equipped with a retaining ring 4 that engages with the dispenser. Currently available dispensers use an arc-shaped groove for engaging with the retaining ring 4, leaving part of the retaining ring 4 exposed. A drive assembly is located on one side of the retaining ring 4 without affecting the normal engagement of the beer spear. A baffle 7 is located on the top of the retaining ring 4. When the drive assembly operates, it causes the baffle 7 to open or close. Simultaneously, a movable claw 8 on the spear tube 3 is linked to the drive assembly. When the drive assembly closes the baffle 7, the movable claw 8 opens; when the drive assembly opens the baffle 7, the movable claw 8 closes. This design of the baffle 7 and movable claw 8 significantly enhances the security of the beer spear, preventing theft of beer from the keg and subsequent tampering or adulteration during the dispensing process. The drive assembly includes a mounting box 9 installed on one side of the snap ring 6. A drive motor 10 is installed inside the mounting box 9. The drive motor 10 has a central shaft 11 connected to the baffle 7. The mounting box 9 is located below the drive motor 10 and has a partition 12. The partition 12 contains a power supply 13, a drive circuit 14, and a push switch 15. The power supply 13, drive circuit 14, push switch 15, and drive motor 10 are electrically connected. By installing the drive motor 10 in the mounting box 9 located on one side of the snap ring 6, the central shaft 11 of the drive motor 10 is connected to the baffle 7 above the snap ring 6 for linkage. At the same time, the partition 12 below the drive motor 10 contains the power supply 13, drive circuit 14, and push switch 15. The power supply 13 controls the drive motor 10 through the drive circuit 14 to drive the baffle 7 and the movable jaw 8 for linkage.

[0028] Example 2: As Figure 1-4As shown in Figure 6, this utility model provides the following technical solution: a movable claw 8 for a spear includes a mounting ring 16 sleeved on a spear tube 3. Several first claw arms 17 are hinged to the mounting ring 16. A second claw arm 18 is hinged to the other end of each first claw arm 17. A claw 19 is hinged to the other end of each second claw arm 18. A first contraction spring 20 is installed between the first claw arm 17 and the spear tube 3. A second contraction spring 21 is installed between the second claw arm 18 and the first claw arm 17. The first contraction spring 20 and the second contraction spring 21 can cause the first claw arm 17 and the second claw arm 18 to be in a contracted state under normal conditions. The second claw arm 18 is linked to a drive motor 10. The first claw arm 17, the second claw arm 18, and the claw... The hinged arrangement between arms 19 allows for a certain amount of movement and range of motion between the claw arms. Simultaneously, the first and second retraction springs 20 and 21 can retract the first claw arm 17 and the second claw arm 18 when the baffle 7 is open, without affecting the normal extraction and use of the spear. The second claw arm 18 is linked to the drive motor 10. When the drive motor 10 operates, it can lift the second claw arm 18, which in turn lifts the first claw arm 17, causing the movable chuck 8 to open. The second claw arm 18 has a connecting hole 22. The central shaft 11, located above the drive motor 10, is fitted with an upper collar 24 and a lower collar 25, forming a connecting groove 26 between the upper and lower collars 24 and 25. The connecting hole 22 and the connecting groove 26 are connected by a connecting line 27. When the central shaft 11 rotates, it can drive the connecting line 27 to open the first claw arm 17 and the second claw arm 18. The second claw arm 18 is provided with a connecting hole 22. The upper collar 24 and the lower collar 25 on the central shaft 11 of the drive motor 10 form the connecting groove 26. The connecting hole 22 and the connecting groove 26 on the second claw arm 18 are connected to the connecting line 27. The connecting line 27 is connected to the connecting groove 26 through the cavity in the valve body 1. When the drive motor 10 starts to work, the drive motor 10 pulls the connecting line 27 to lift the second claw arm 18, which is a linkage action. When the drive motor 10 reverses, the connecting line 27 also resets at the same time. The second claw arm 18 is reset by the first retraction spring 20 and the second spring 23. The spear tube 3 includes an outer tube 301 and an inner tube 302 disposed inside the outer tube 301. The center of the inner tube 302 is a flow channel 28. The outer tube 301 is a solid tube. The outer wall of the outer tube 301 is provided with a mounting groove 29 for mounting the mounting ring 16 and the movable claw 8. The mounting groove 29 is provided on the surface of the outer tube 301. Since the outer tube 301 is a solid tube and the inner tube 302 is provided with a flow channel in the center, the embedded groove for the movable claw 8 and the mounting ring 16 to be embedded in the inner tube will not affect the normal use of the inner tube 302. At the same time, the setting of the embedded groove greatly reduces the overall volume of the movable claw 8 after installation.
