Description

Technical Field

[0001] The invention relates to the field of water cup accessories, and in particular to a universal bottle mouth cock and a use method thereof. Background Art

[0002] As a common water container in daily life, water cups bring many conveniences to people, but their functions are relatively simple. The main function of most ordinary water cups is to hold and store drinking water. Although some water cups have added heat preservation functions, their functions have many defects when used. Specifically, most of the current thermos cups are composed of a cup body and a screw-type cup cover. The cup cover is sealed by rotating with a threaded interface with the cup body. It is inconvenient to open and close the cup cover by vigorously rotating the cup cover for several circles to maintain the sealing function of the bottle mouth, and there is a problem that the threads are misaligned and cannot be screwed on because the cup cover is not flat when closing. In addition, when the cup is filled with hot water, the cup body, cup cover, sealing ring and other materials expand due to heat, and the air in the cup body expands due to heat and is discharged out of the cup. After the water cools down, the material shrinks and the internal air pressure decreases, causing the cup cover to stick and need to be rotated vigorously to open, further increasing the inconvenience of use.

[0003] At the same time, after the current cup lid is opened, the entire inner cavity of the cup is exposed. After the hot water inside is cooled to a warm state suitable for drinking, since the water in the thermos cup usually cannot be drunk all at once, when drinking it again, the water will continue to cool down during the interval between two drinks even if the cup lid is closed, resulting in the water temperature being lower than the suitable drinking range when drinking it again, affecting the insulation effect of the thermos cup.

[0016] The method for using the universal bottle mouth cock comprises the following steps:

[0017] a. When installing the bottle cap, hold the cover plate and rotate the synchronizer ring, and use the multiple arc-shaped transmission grooves on the synchronizer ring to support the rotation of the transmission rods of the multiple sets of locking parts, so as to synchronously squeeze the free ends of the outer sides of the multiple sets of rotating arms toward the core barrel, and use the rotating arm to compress the torsion spring, then synchronously place the cover plate, core barrel, synchronizer ring and multiple sets of locking parts into the inner side of the cup opening, and loosen the synchronizer ring after the blocking ball is aligned with the positioning hole, and use the torsion spring to push the rotating arm outward to expand, and then synchronously insert the multiple sets of blocking balls into the positioning holes on the inner side of the cup opening, so as to complete the positioning of the core barrel and the cover plate at the port of the cup body, and at the same time, the compression spring pushes the synchronizer ring downward through the support of the cover plate, and the synchronizer ring is pressed against the top edge of the cup body under the guidance of the outer wall of the core barrel, so as to complete the installation process of the bottle cap;

[0018] b. When unscrewing the bottle cap, hold the cup body and rotate the synchronizer ring, and use the arc-shaped transmission groove on the synchronizer ring to support multiple groups of transmission rods to drive the rotating arm to retract. At the same time, the rotating arm drives the blocking ball to escape from the positioning hole of the cup body. At this time, the closed state of the positioning hole is released, and the cup body is connected to the external air environment. The air pressure inside and outside the cup body is kept consistent. At the same time, since the locking state of the locking piece on the inner wall of the cup body is released, the spring in the compressed state above pushes the cover plate upward under the support of the synchronizer ring to bounce the cover plate, the core tube and multiple groups of locking pieces upward, thereby quickly realizing the separation of the blocking ball and the positioning hole, and completing the unscrewing of the bottle cap;

[0019] c. When drinking the hot water inside the cup body with the bottle cap installed, turn the cup body upside down and press the pressure handle to separate the cone disk at the end of the probe rod from the cone hole of the core barrel. At this time, the hot water inside the cup body enters the core barrel along the cone hole in the inverted state. Adjust the amount of water injected into the core barrel according to the amount of drinking at a time, and then put the cup body upright and flip the movable cover upward. At this time, part of the hot water in the core barrel is in the open state to cool, and the remaining hot water in the cup body is still in a closed and heat-insulating state, so that the hot water in the cup body can be drunk in batches;

[0020] d. When the movable cover is opened, the guide rod presses the bent and retracted straw downward to reset upward under its own elastic action, and the straw is propped up and extends out of the core tube. At this time, the straw is connected with the lower extension tube through the connecting hole of the floating head and the lower hole of the sealing tube. Under normal conditions, the straw can be used to directly suck the water in the cup body for drinking. If cooled water is introduced into the core tube and needs to be drunk, the straw is pulled upward to drive the hoop sleeve, the hoop ring and the floating head to move up. At this time, the floating head connected to the lower hole moves up to the upper hole, and then the straw is connected to the core tube through the upper hole and the connecting hole. At this time, the water sucked out by the straw is the cooled drinking water in the core tube;

[0021] e. When the straw is pulled up and adjusted to the state of connecting to the core barrel, and then when the straw needs to be connected to the cup body again, the movable cover is flipped down to drive the guide rod to reset. When the bent section at the bottom of the guide rod rotates to the hoop position of the bottom end of the straw in the expanded state, the bent section presses the hoop downward to push the hoop and its inner hoop ring and the floating head downward to reset. While the guide rod is used to retract the straw into the core barrel, the floating head is moved down and reset. The straw is connected to the lower hole again through the floating head, and connected to the cup body along the lower hole in cooperation with the extension tube.

[0022] The beneficial effects are as follows: 1. The present invention provides multiple groups of outwardly deployable locking pieces as quick disassembly and assembly structures for connecting the inner wall of the cup body, and provides a synchronization ring with an arc groove to synchronously connect the multiple groups of locking pieces, so that the rotating arms can be synchronously deployed and retracted, so that cup bodies of different sizes can be replaced according to different places of use, thereby realizing the universal function of the stopper bottle cap;

[0023] 2. In addition, by rotating the synchronous ring, the transmission groove pushes the locking piece back, and the compression spring keeps the synchronous ring against the top edge of the cup body to achieve sealing, which can realize the quick opening function of the bottle cap, replacing the cumbersome operation steps of multiple turns of the traditional threaded rotary seal. After the locking piece is released, the core barrel and the cover plate can be automatically popped up, so as to open the positioning hole to achieve the same air pressure inside and outside, solve the problem of negative pressure adsorption caused by water temperature cooling, and improve the convenience of opening the cap;

[0024] 3. At the same time, a core barrel is provided as a separate cooling cavity for single drinking. The core barrel can be opened separately to cool the single drinking amount of water while keeping the inside of the cup body closed, thereby ensuring that the remaining water in the cup body is continuously kept warm, so that the water temperature will not be lower than the suitable drinking temperature range during subsequent drinking, thereby improving the heat preservation effect of the water cup.

A torsion spring 603 is arranged at the hinge between the rotating arm 601 and the core barrel 2 to keep the rotating arm 601 pressed outward, and the blocking ball 604 is made of rubber material to ensure that the blocking ball 604 can close the positioning hole 301 after being pressed against the inner opening of the positioning hole 301. A vertically extending transmission rod 605 is fixed on the top side of the rotating arm 601, and a compression spring 401 is arranged between the top side of the synchronous ring 4 and the cover plate 1, and the synchronous ring 4 is pressed to the top edge of the cup body 3 by the compression spring 401 to maintain the seal, and an arc-shaped transmission groove 403 (such as the arc-shaped transmission groove 403) with a clearance to fit the transmission rod 605 is arranged on the bottom side of the synchronous ring 4 Fig.13 As shown), when the synchronizer ring 4 is rotated, the transmission groove 403 can be used to support the transmission rod 605 to drive the rotating arm 601 to retract or extend.

[0044] As an optional embodiment, the compression spring 401 is sleeved on the outside of the core barrel 2, and the bottom side of the cover plate 1 is provided with a mounting groove 101 for accommodating the compression spring 401, so as to improve the installation stability of the compression spring 401. A plurality of groups of arc-shaped holding grooves 402 for convenient grasping are arranged around the outer circumference of the synchronization ring 4, and a plurality of groups of rotating ears 201 are arranged on the outer circumference of the core barrel 2 corresponding to the rotating arm 601. A shaft 602 for rotating and matching the rotating ears 201 is fixed at the end of the rotating arm 601, and a torsion spring 603 is sleeved on the outside of the shaft 602. The inner side of the cup body 3 is provided with a guide groove 302 which is connected to the positioning hole 301 along the top opening downward, so that the plugging ball 604 can be slid into the positioning hole 301 along the guide groove 302 when installing the stopper bottle cap. When the plugging ball 604 is not inserted into the guide groove 302 or the positioning hole 301, the core barrel 2 is rotated to drive the multiple sets of locking members 6 to rotate until the plugging ball 604 rotates into the guide groove 302. The guide groove 302 plays a role in rotational positioning of the plugging ball 604 and the core barrel 2, so that the stopper bottle cap can be installed quickly and conveniently.

[0045] A semicircular fixed cover 102 and a movable cover 105 are provided in the middle of the cover plate 1. A sealing hole 103 for accommodating the probe rod 5 is vertically penetrated in the middle of the fixed cover 102. A sealing rubber ring is provided inside the sealing hole 103. A tapered hole 203 is vertically penetrated at the bottom of the core tube 2 corresponding to the probe rod 5. The probe rod 5 includes a rod body 501 which penetrates the sealing hole 103 and the tapered hole 203 in sequence. A tapered disk 502 which fits the tapered hole 203 is fixed at the bottom of the rod body 501 to improve the compression and sealing effect of the tapered disk 502 on the tapered hole 203.

[0046] In addition, a pressing handle 505 is fixed to the top of the rod body 501, and a pressing cap 503 is fixed to the middle section of the rod body 501. A vertically extending connecting groove 501a is arranged around the outside of the rod body 501 between the pressing cap 503 and the cone disk 502, so as to ensure that after the cone disk 502 is pressed down and separated from the cone hole 203, the hot water in the cup body 3 in the flipped state can be guided to be injected into the core tube 2 through the gap between the connecting groove 501a of the rod body 501 and the cone hole 203, and a self-sealing spring 504 is sleeved on the outside of the rod body 501 below the pressing cap 503, which is pressed against the inner bottom wall of the core tube 2, so as to push the pressing cap 503 upward, thereby maintaining the pressing and sealing effect of the cone disk 502 on the cone hole 203;

[0047] A rotating shaft 104 for supporting the movable cover 105 to flip upward and open is arranged on the inner side of the cover plate 1 above the fixed cover 102, and a guide rod 7 with its bottom end inclined toward the direction close to the probe rod 5 is arranged below the movable cover 105. The guide rod 7 is a U-shaped structure, and the bottom end of the guide rod 7 is bent upward to form a group of connecting sections 701 and two groups of bending sections 702. A rubber straw 9 is passed through the middle of the guide rod 7. The outer diameter of the straw 9 is smaller than the width of the gap on the front and rear sides of the guide rod 7 to ensure that the straw 9 can move in the middle of the guide rod 7. The top of the straw 9 expands outward to form a clamping ring 902, which is used to prevent the top of the straw 9 from passing through the guide rod 7 downward. The bottom end of the straw 9 is connected with a connector 8, and an auxiliary hole 204 for installing the connector 8 is arranged on the side of the bottom of the core tube 2 away from the tapered hole 203. The bottom end of the connector 8 passes through the core tube 2 and is connected with an extension tube 10 extending into the cup body 3;

[0048] The connector 8 includes a cylindrical sealing cylinder 801, the outer portion of which is provided with an upper hole 801b connected to the inner cavity of the core cylinder 2 and a lower hole 801a connected to the inner cavity of the cup body 3. A floating head 802 is vertically slidably arranged inside the sealing cylinder 801. The floating head 802 is a cylindrical structure with an open top and a closed bottom. Piston rings 803 are fixed to the bottom and middle of the floating head 802. The piston rings 803 are slidably sealed with the inner wall of the sealing cylinder 801. A connecting hole 802a is penetrated through the outer wall of the floating head 802 between the two groups of piston rings 803. When the straw 9 is pulled upward and the two groups of piston rings 803 follow the floating head 802 to move up to the position of the upper hole 801b, the connecting hole 802a of the floating head 802 connects the straw 9 with the inner cavity of the core cylinder 2. The top end of the floating head 802 extends out of the sealing cylinder 801, and the top end of the floating head 802 expands outward to form a hoop 804. The bottom end of the suction tube 9 is sleeved on the outside of the hoop ring 804 to form a hoop sleeve 901. The outer diameters of the hoop sleeve 901 and the clamping ring 902 are both larger than the width of the gap on the front and rear sides of the guide rod 7. The top of the extension tube 10 is provided with a connecting sleeve 10a sleeved on the outside of the sealing tube 801, and the connecting sleeve 10a is connected with the sealing tube 801 through the lower hole 801a. When it is necessary to move the floating head 802 downward and reset, the movable cover 105 is closed to push the guide rod 7 to rotate toward the direction close to the probe rod 5, and the bent section 702 at the bottom end of the guide rod 7 rotates to the position of the hoop sleeve 901, and the bent section 702 presses down the hoop sleeve 901, so as to use the hoop sleeve 901 to drive the inner hoop ring 804 and the floating head 802 to move downward, and then the connecting hole 802a is connected with the lower hole 801a again, and the position stability of the floating head 802 in the sealing tube 801 is maintained by the friction between the piston ring 803 and the inner wall of the sealing tube 801.

[0049] A slide groove 107 is horizontally arranged on one side of the top of the cover plate 1 near the movable cover 105, and a slide key 11 is horizontally slidably arranged inside the slide groove 107 for pressing down and locking the movable cover 105. A limit frame 106 is fixed to the side wall of the cover plate 1 outside the slide groove 107, and a light rod 11a is fixed to the bottom of the slide key 11 to horizontally penetrate the limit frame 106. A return spring 11b is sleeved on the outer side of the light rod 11a and pressed against the limit frame 106. The slide key 11 is pressed against the top side of the movable cover 105 to maintain the sealing effect of the movable cover 105 on the inner top opening of the cover plate 1. At the same time, the slide key 11 can be pushed outward to release the downward pressure positioning of the movable cover 105. At this time, the straw 9 (such as Figure 4 As shown in the figure, the movable cover 105 can be pushed and opened automatically under the action of its own elastic force, and the outer side of the limiting frame 106 is connected with a hand strap 12 for conveniently picking up the whole water cup.

[0050] The method for using the universal bottle cock comprises the following steps:

[0051] a. When installing the bottle cap, hold the cover plate 1 and rotate the synchronizer ring 4, and use the multiple arc-shaped transmission grooves 403 on the synchronizer ring 4 to support the transmission rod 605 of the multiple sets of locking members 6 to rotate, so as to synchronously squeeze the outer free ends of the multiple sets of rotating arms 601 toward the core barrel 2, and use the rotating arms 601 to compress the torsion springs 603, then synchronously place the cover plate 1, the core barrel 2, the synchronizer ring 4 and the multiple sets of locking members 6 into the inner position of the opening of the cup body 3, and then release the synchronizer ring 4 after the blocking ball 604 corresponds to the positioning hole 301, and use the torsion spring 603 to push the rotating arm 601 to expand outward, and then synchronously insert the multiple sets of blocking balls 604 into the positioning holes 301 on the inner side of the opening of the cup body 3, so as to complete the positioning of the core barrel 2 and the cover plate 1 at the inner port of the cup body 3, and at the same time, the compression spring 401 pushes the synchronizer ring 4 downward through the support of the cover plate 1, and presses the synchronizer ring 4 against the top edge of the cup body 3 under the guidance of the outer wall of the core barrel 2, so as to complete the installation process of the bottle cap;

[0052] b. When unscrewing the bottle cap, hold the cup body 3 and rotate the synchronizer ring 4, and use the arc-shaped transmission groove 403 on the synchronizer ring 4 to support the multiple transmission rods 605 to drive the rotating arm 601 to retract, and at the same time, the rotating arm 601 drives the blocking ball 604 to escape from the positioning hole 301 of the cup body 3. At this time, the closed state of the positioning hole 301 is released, and the cup body 3 is connected to the external air environment. The air pressure inside and outside the cup body 3 is consistent. At the same time, since the locking state of the inner wall of the cup body 3 by the locking piece 6 is released, the spring in the compressed state above pushes the cover plate 1 upward under the support of the synchronizer ring 4, so as to bounce the cover plate 1, the core tube 2 and the multiple locking pieces 6 upward, so as to quickly separate the blocking ball 604 from the positioning hole 301, and complete the unscrewing of the bottle cap;

[0053] c. When drinking the hot water in the cup body 3 with the bottle cap installed, invert the cup body 3 and press the pressure handle 505 to separate the cone disk 502 at the end of the probe 5 from the cone hole 203 of the core barrel 2. At this time, the hot water in the cup body 3 in the inverted state enters the core barrel 2 along the cone hole 203. The amount of water injected into the core barrel 2 is adjusted according to the amount of water to be drunk at a time. Then, the cup body 3 is placed upright and the movable cover 105 is opened upward. At this time, part of the hot water in the core barrel 2 is in the open state for cooling, and the remaining hot water in the cup body 3 is still in a closed and heat-insulating state, so that the hot water in the cup body 3 can be drunk in batches;

[0054] d. When the movable cover 105 is opened, the guide rod 7 presses the bent and retracted straw 9 downward to reset itself upward under its own elastic action, and the straw 9 is propped up and extends out of the core tube 2. At this time, the straw 9 is connected with the lower extension tube 10 through the connecting hole 802a of the floating head 802 and the lower hole 801a of the sealing tube 801. Under normal conditions, the straw 9 can be used to directly absorb the water in the cup body 3 for drinking. If cooled water is introduced into the core tube 2 and needs to be drunk, the straw 9 is pulled upward to drive the hoop 901, the hoop ring 804 and the floating head 802 to move upward. At this time, the floating head 802 connected with the lower hole 801a moves upward to the upper hole 801b, and then the straw 9 is connected with the core tube 2 through the upper hole 801b and the connecting hole 802a. At this time, the water sucked out by the straw 9 is the cooled drinking water in the core tube 2.

[0055] e. When the straw 9 is pulled up and adjusted to the state of connecting to the core tube 2, and then when the straw 9 needs to be connected to the cup body 3 again, the movable cover 105 is flipped downward to drive the guide rod 7 to reset. When the bent section 702 at the bottom of the guide rod 7 rotates to the position of the hoop 901 in the outward expansion state of the bottom end of the straw 9, the bent section 702 presses the hoop 901 downward to push the hoop 901 and its inner hoop ring 804 and the floating head 802 downward to reset. Therefore, when the guide rod 7 is used to retract the straw 9 into the core tube 2, the floating head 802 is moved down and reset. Therefore, the straw 9 is connected to the lower hole 801a again through the floating head 802, and is connected to the cup body 3 along the lower hole 801a in cooperation with the extension tube 10.

[0056] A plurality of groups of lock members 6 that can be deployed outward are provided as a quick disassembly and assembly structure for connecting the inner wall of the cup body 3, and a synchronization ring 4 with an arc groove is provided to synchronously connect the plurality of groups of lock members 6, and the rotating arm 601 can be synchronously deployed and retracted, so that the cup body 3 of different sizes can be replaced according to different places of use, thereby realizing the universal function of the stopper bottle cap;

[0057] In addition, by rotating the synchronizer ring 4 so that its transmission groove 403 pushes the locking piece 6 back, and by the compression spring 401, the synchronizer ring 4 is kept against the top edge of the cup body 3 to achieve sealing, the bottle cap can be quickly opened, replacing the cumbersome operation steps of rotating the traditional threaded seal for multiple circles, and the core barrel 2 and the cover plate 1 can be automatically bounced upward after the locking piece 6 is released, so as to open the positioning hole 301 to achieve the consistency of the internal and external air pressures, solve the problem of negative pressure adsorption caused by water temperature cooling, and improve the convenience of opening the cap;

[0058] At the same time, the core barrel 2 is provided as a separate cooling cavity for single drinking. The core barrel 2 can be opened separately to cool the single drinking amount of water while keeping the cup body 3 in a closed state, thereby ensuring that the remaining water in the cup body 3 is continuously kept warm, so that the water temperature will not be lower than the suitable drinking temperature range during subsequent drinking, thereby improving the insulation effect of the water cup.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

10. The method for using the universal bottle cock according to claim 9, characterized in that: The following steps are involved: a. When installing the bottle cap, hold the cover plate (1) and rotate the synchronizer ring (4), and use the multiple arc-shaped transmission grooves (403) on the synchronizer ring (4) to support the transmission rods (605) of the multiple sets of locking pieces (6) to rotate, so as to synchronously press the outer free ends of the multiple sets of rotating arms (601) toward the core tube (2), and at the same time use the rotating arms (601) to compress the torsion spring (603), and then synchronously place the cover plate (1), the core tube (2), the synchronizer ring (4) and the multiple sets of locking pieces (6) into the inner side of the opening of the cup body (3), and place the blocking ball (601) in the inner side of the cup body (3). 4) After the corresponding positioning hole (301) is aligned, the synchronous ring (4) is loosened, and the rotating arm (601) is pushed outward by the torsion spring (603), thereby synchronously inserting the plurality of blocking balls (604) into the positioning holes (301) on the inner side of the opening of the cup body (3), thereby completing the positioning of the core barrel (2) and the cover plate (1) at the inner port of the cup body (3). At the same time, the compression spring (401) pushes the synchronous ring (4) downward through the support of the cover plate (1), and the synchronous ring (4) is pressed against the top edge of the cup body (3) under the guidance of the outer wall of the core barrel (2), thereby completing the installation process of the bottle cap; b. When unscrewing the bottle cap, the cup body (3) is held and the synchronous ring (4) is rotated. The arc-shaped transmission groove (403) on the synchronous ring (4) is used to support the multiple transmission rods (605) to drive the rotating arm (601) to retract. At the same time, the rotating arm (601) drives the blocking ball (604) to escape from the positioning hole (301) of the cup body (3). At this time, the closed state of the positioning hole (301) is released, the cup body (3) is connected to the external air environment, and the air pressure inside and outside the cup body (3) is kept consistent. At the same time, since the locking state of the locking member (6) on the inner wall of the cup body (3) is released, the spring in the compressed state at the top pushes the cover plate (1) upward under the support of the synchronous ring (4), so that the cover plate (1), the core tube (2) and the multiple locking members (6) are bounced upward, thereby quickly realizing the separation action of the blocking ball (604) and the positioning hole (301), and completing the unscrewing of the bottle cap; c. When drinking the hot water in the cup body (3) with the bottle cap installed, the cup body (3) is inverted and the pressure handle (505) is pressed to separate the cone disk (502) at the end of the probe rod (5) from the cone hole (203) of the core barrel (2). At this time, the hot water in the cup body (3) in the inverted state enters the core barrel (2) along the cone hole (203). The amount of water injected into the core barrel (2) is adjusted according to the amount of water to be drunk at a time. Then, the cup body (3) is placed upright and the movable cover (105) is flipped upward. At this time, part of the hot water in the core barrel (2) is in the open cover state for cooling, and the remaining hot water in the cup body (3) is still in a closed and heat-insulating state, so that the hot water in the cup body (3) can be drunk in batches; d. When the movable cover (105) is opened, the guide rod (7) presses the straw (9) in the bent and retracted state downwardly and resets it upwardly under the action of its own elasticity. The straw (9) is propped up and extends out of the core tube (2). At this time, the straw (9) is connected to the lower extension tube (10) through the connecting hole (802a) of the floating head (802) and the lower hole (801a) of the sealing tube (801). Under normal conditions, the straw (9) can be used to directly absorb the water in the cup body (3) for drinking. If the core tube ( 2) When cooled water is introduced into the core tube for drinking, the straw (9) is pulled upward to drive the hoop (901), the hoop ring (804) and the floating head (802) to move upward. At this time, the floating head (802) connected to the lower hole (801a) moves upward to the position connected to the upper hole (801b), and then the straw (9) is connected to the core tube (2) through the upper hole (801b) and the connecting hole (802a). At this time, the water sucked out by the straw (9) is the cooled drinking water in the core tube (2); e. When the straw (9) is pulled up to be adjusted to a state of being connected to the core tube (2), and then when it is necessary to connect the straw (9) to the cup body (3) again, the movable cover (105) is flipped downward to drive the guide rod (7) to reset. When the bent section (702) at the bottom end of the guide rod (7) rotates to the position of the hoop sleeve (901) in the outward expansion state of the bottom end of the straw (9), the bent section (702) presses the hoop sleeve (901) downward to push the hoop sleeve (901) and its inner hoop ring (804) and the floating head (802) downward to reset. Thus, when the guide rod (7) is used to retract the straw (9) into the core tube (2), the floating head (802) is moved downward to reset. Thus, the straw (9) is connected to the lower hole (801a) again through the floating head (802), and is connected to the cup body (3) along the lower hole (801a) in cooperation with the extension tube (10).
