Description

Automatic fishing device triggered by lever and rolling mode

The technical field is as follows: the device is a mechanical automatic fishing device capable of automatically contracting.

Secondly, the background technology: it is known that the sliding friction is larger than the rolling friction, but most of the prior automatic fishing devices are triggered by overcoming the sliding friction, which causes the required force for triggering to be large and the performance to be unreliable and unstable. Although the device named as "automatic fishing device for fishing on the top and bottom of sea rod" disclosed in the chinese patent publication No. CN1871905 by 2006 is triggered in a rolling manner, and comprises a support rod 7 fixed on the sea rod, a support rod front end 8 (the front end surface thereof is a support surface), a tension member 6 on the support rod, a slide pipe 5, a suspension loop 4 with both ends connected with adjacent parts by hinges, and a wheel 2 with a handle 1 or without a handle 1 which can be placed on the suspension loop at the front end of the support rod before fishing, it cannot be used for floating fishing because of the following reasons: 1. the support rod 7 is fixed on the fishing rod; 2. the upper end of the supporting rod is not provided with a main wire fastening hole; 3, when the wheel 2 of the device is triggered at the front end 8 of the supporting rod in a rolling mode, in order to adapt to the requirement of bottom fishing, the wheel 2 and the handle 1 connected with a fishing line on the wheel can be poured to two sides of the supporting rod 7, namely the wheel can be poured to the right side of the supporting rod 7 and can also be poured to the left side of the supporting rod, and the fishing line is easy to be disordered if the fishing line is used for floating fishing; 4. the fishing device is in a standby state due to the fact that the wheel 2 and the handle 1 which are tied with the fishing line can be balanced and stable at the top end of the front end 8 of the semicircular supporting rod, and the device is achieved by means of the weight of heavy weights or large baits which are positioned at the bottom of the water during bottom fishing, but the device does not have the condition during floating fishing.

The device named as the multifunctional sleeve telescopic automatic fishing device which is published by the inventor of 2016 Chinese patent publication No. CN105707029A adopts split force and lever force for triggering, so that the triggering design is well solved, and a good effect is achieved, but the device has the advantages of high manufacturing cost, inconvenient installation and large market popularization resistance.

The purpose of the invention is as follows: the invention aims to design an automatic fishing device which is mainly used for floating fishing and is triggered in a rolling and lever force mode, wherein the rolling and lever force mode has the advantages of small force required for triggering, reliable and stable performance and lower cost.

Fourthly, the invention content: an automatic fishing device triggered by lever and rolling mode is composed of supporting rod, supporting surface, pressure spring or pull part, D-shaped ring, slide tube, non-return part, prompting rod, float, fishing line, hook and weight.

The concrete structure and connection are as follows:

the upper end of a strip-shaped supporting rod is provided with a main line fastening hole, and the supporting rod is sleeved with a pressure spring or the upper part of the supporting rod is provided with a tension piece fastening hole. The lower part of the supporting rod is provided with a supporting surface which is in a disc split shape or a step shape, the tension member is a tension spring or a rubber band, the upper end of the tension member is connected with a tension member fastening hole at the upper part of the supporting rod, the lower end of the tension member is movably connected with a cylinder at the straight part of the D-shaped ring, or the upper part of the tension member is connected with a tension member fastening hole of the supporting rod, the lower end of the tension member is connected with a sliding tube tension member fastening hole at the upper part of a sliding tube sleeved on the supporting rod, and then the lower part of the sliding tube is connected with the cylinder at the straight part of the D-shaped ring through D. The straight part of the D-shaped ring is the linear sealing part of the D-shaped ring body, which is equivalent to the sealing part of the U-shaped ring, and is called as the straight part of the D-shaped ring for the convenience of description because the D-shaped ring is of a straight shape. The straight part of the D-shaped ring is a cylinder except for two ends and the connection part with the ring arm of the D-shaped ring, the straight part of the D-shaped ring and the ring arm of the D-shaped ring are fixedly connected or the straight part of the D-shaped ring and the ring arm of the D-shaped ring are originally continuous and integrated, namely, the D-shaped ring comprises a U-shaped ring body and a straight part which are formed by winding round wires and are formed by casting, turning and forging, the straight part of the former D-shaped ring is fixedly connected with the two ring arms of the U-shaped ring body, and the straight parts of the latter 4D-shaped rings and the two arms of the D-shaped ring are continuous and integrated. Because the straight part of the D-shaped ring is fixedly connected with the two ring arms or is a continuous integral structure, the straight part of the D-shaped ring also rotates when the D-shaped ring arms rotate. The D-shaped ring is provided with a fish wire hole. When the pressure spring is adopted, the upper end of the pressure spring sleeved on the supporting rod is movably connected with the cylinder at the straight part of the D-shaped ring through an extended spring wire or a connecting piece 8-shaped ring, a metal straight wire or other flexible wires.

The main line is connected with a main line bolt hole at the upper end of the supporting rod, the sub line is connected with a fishing line hole on the D-shaped ring, the float is connected on the main line above the upper end of the supporting rod, the main line above the float is provided with space beans, the fishing depth is adjusted by moving the space beans on the main line, when the fishing device is installed before fishing, the straight part of the D-shaped ring moves downwards or the sliding tube moves downwards to stretch a tension piece or compress a pressure spring, then the cylinder of the straight part of the D-shaped ring or the cylinder of the straight part of the D-shaped ring in the sliding tube hole is placed on the supporting surface of the supporting rod, namely the D-shaped ring is hung on the supporting surface of the supporting rod, and the end of the D-shaped ring with the fishing line hole rotates to the side of the supporting rod to ensure that the intersecting angle of the ring arm of the D-shaped ring and the longitudinal axis of the supporting rod is visually measured to be a right angle, after the fishing device is installed and thrown into water, when, the cylinder at the straight part of the D-shaped ring or the cylinder at the straight part of the D-shaped ring in the tube hole of the sliding tube rolls outwards on the supporting surface of the supporting rod in a lever force and rolling mode until the D-shaped ring is separated from the supporting rod, and the D-shaped ring moves upwards under the pulling force of the tension piece or the elastic piece, so that the sub-line is driven to move upwards, and the fishhook retracts to fish.

The float and line group connection method is a common method, and the float and line group connection method is simple, and intuitive and convenient to operate.

In addition, the connection method of the float and the line group is that the float is connected with the upper part of the support rod, the main line is connected with a main line fastening hole at the upper end of the support rod, and the sub line is connected with a fishing line hole on the D-shaped ring, so the method is simple and convenient, but the fishing depth cannot be adjusted.

The two floating and line group connecting methods are suitable for the supporting surface in a step shape and the supporting surface in a disc split shape.

The holding surface divides the disc into two kinds of lamellas and step form, but the bracing piece has three kinds:

the first method comprises the following steps: the supporting rod is a round rod, the lower part of the round rod-shaped supporting rod is expanded into a disc, and the disc is divided into split supporting surfaces by the grooves.

And the second method comprises the following steps: the support rod is flat or rectangular, and the lower part of the support rod is provided with 1 step-shaped support surface.

And the third is that: the support rod is flat or rectangular, and the lower part of the support rod is provided with 2 step-shaped support surfaces.

When the support rod is flat or rectangular and the lower part of the support rod is provided with 1 or 2 step-shaped support surfaces, the support rod is provided with a section of support rod extension section downwards from the support surface, and the tail end of the support rod extension section is provided with a film fastening hole.

The bracing piece extension section that sets up this moment has following meaning:

1. the device has the function of limiting the D-shaped ring, so that the end of the D-shaped ring where the fishing line hole is positioned is always positioned on the outer side of the supporting surface of the supporting rod before installation and after triggering, namely the opposite side of the free end of the supporting surface, namely the side B of the supporting rod, when the fishing line is connected in a straight-through mode, the wire passing ring at the upper end of the side B of the supporting rod and the wire passing hole fixed on the buoy at the upper part of the supporting rod and positioned in the direction of the side B of the supporting rod are consistent in direction, and.

2. When the fishing device is installed, two hands are needed to operate, and the extension section of the supporting rod is arranged, so that the two hands have holding parts, and the fishing device is convenient to install.

3. Due to the existence of the extension section of the supporting rod, the cylinder is provided with a backrest, so that the cylinder in the slide pipe hole is relied on during and after installation, and the fishing device is convenient to install and cast successfully. If the support rod extension section is not arranged, the position of the cylinder at the straight part of the D-shaped ring on the support surface of the support rod is not easy to be placed correctly in time during installation, the cylinder at the straight part of the D-shaped ring is unstable on the support surface and easily slides out of the support surface automatically, even if the cylinder does not slide out, the cylinder can slide out immediately after being thrown gently and shaken, and the cylinder at the straight part of the D-shaped ring can also slide out of the platform without a backrest to cause ineffective triggering when the fishing line is thrown in a straight-through mode.

4. The film is tied on the supporting rod, the extending section of the supporting rod and the extending section of the D-shaped ring are wound and wrapped by the film, and the fishing device can be temporarily locked to prevent the fishing device from being triggered by mistake in throwing.

When the support rod is in a flat long shape or a rectangular shape and the lower part of the support rod is provided with 1 or 2 step-shaped support surfaces, if the fishing device is used for throwing the fishing device at a great distance, the D-shaped ring is also provided with a section of downward extension section, the extension section is used for tying a strip-shaped thin film in a hole at the tail end of the extension section of the support rod as a temporary locking film, after the fishing device is installed and before the fishing device is thrown, the extension section of the support rod and the extension section of the D-shaped ring are wound and wrapped together by the thin film which is wetted by water to play a role of temporarily locking the fishing device, and after the fishing device is thrown into the water, the thin film can be automatically loosened to unlock the fishing device under the impact and the shaking of the water.

The length of the extension of the support rod and the extension of the D-shaped ring can be equal to or slightly longer than that of the D-shaped ring, and if the length of the extension of the support rod and the extension of the D-shaped ring is shorter than that of the D-shaped ring, a cross bar can be arranged between the two ring arms of the D-shaped ring, so that the support rod and the extension of the D-shaped ring can also have the functions.

The float and the line group connection method are two common methods, both of which are suitable for all three support rods and support surfaces thereof, the two line group connection methods are that a main line is separated from a sub line, the main line is not directly connected with the sub line,

it will be described that when the support bar is oblong or rectangular and the lower part thereof has 1 or 2 step-like support surfaces, it is also possible to use a connection method of floats and line groups which is more complicated in third and fourth modes and is more complicated to operate during fishing, and the connection modes of the third and fourth floats and line groups are all direct connection modes of line groups, i.e. the main line is directly connected with the sub-line. The third mode is that the buoy is connected with the upper part of the supporting rod, the line group is connected in a straight-through mode, namely, a main line sequentially penetrates through a line passing ring on the upper part of the supporting rod or a line passing hole on the buoy from top to bottom, penetrates through a fish line hole of the D-shaped ring, is connected with a sinker with the diameter larger than that of the fish line hole and then is connected with a sub line, and meanwhile, a space bean with the diameter smaller than that of the line passing ring hole on the supporting rod or the line passing hole on the buoy and larger than that of the fish line hole is required to penetrate through the main line. The fourth mode is that the buoy is connected on the main line, and the line group is also connected in a straight-through mode, namely, the main line passes through the line passing ring at the upper part of the supporting rod, then passes through the fishing line hole of the D-shaped ring downwards, and is connected with the sub line after being connected with the pendant.

However, when the support rod is oblong or rectangular and has one or 2 step-shaped support surfaces, and the wire groups are connected in a straight-through manner, a backstop is required. The function of the backstop is used for limiting the movement of the D-shaped ring when the fishing line is connected in a straight-through mode, so that the D-shaped ring cannot excessively rotate reversely when the casting fishing device is used for fishing, namely cannot excessively move upwards, so that the triggering mechanism can be maintained in an optimal and sensitive state to be triggered after being installed and after being cast, and the backstop can be used when the fishing line is connected in a mode other than the straight-through mode.

It should be noted that, when the support rod is in the shape of a circular rod and the support surface thereof is in the shape of a split, the wire group is connected in a straight-through manner, and the disc-shaped support surface limits the reverse movement of the D-shaped ring, so that a backstop is not required.

The design scheme of the backstop is as follows:

when the tension member is connected with the straight part of the D-shaped ring, the straight part of the D-shaped ring is provided with a backstop formed by an upward extending section in an inclined way, which is called as the backstop of the extending section of the straight part of the D-shaped ring; or the ring arm of the D-shaped ring is provided with a backstop formed by an upward extending section in an inclined way, which is called as the backstop of the upper extending section of the ring arm of the D-shaped ring; when the tension piece is connected with the upper part of the sliding pipe, a backstop piece is arranged on the sliding pipe or a backstop piece is arranged on an extending section on a D-shaped ring arm formed by an obliquely upward extending section of a D-shaped ring arm; the non-return moving part of the extending section on the D-shaped ring arm is divided into a single-piece type, a double-piece type and a double-piece type. When the anti-reverse moving part is required to be arranged, one of the anti-reverse moving parts can be selected.

When the support rod is flat long or rectangular and its lower portion has 1 or 2 step-like support surfaces and the float is connected on the upper portion of the support rod, the main line is connected by adopting straight-through mode, at this time, the upper end of support rod B side must be equipped with line-passing ring or line-passing hole on the float, and the main line is passed through the line-passing ring or line-passing hole fixed on the upper portion of support rod in the direction of support rod B side from top to bottom, then passed through fish-line hole on D-ring, then connected with sub-line, and when adopting said mode, the main line above the fish-line hole of D-ring must be passed through the line-passing ring whose external diameter is greater than that of fish-line hole on D-ring and smaller than that of fish-line hole on support rod B side and the space bean fixed on the float on the upper portion of support rod and positioned in the direction of support rod B side, and must be equipped with sinker capable of pulling fish, the sinker has the function that after the fishing device is thrown, the main line can smoothly run downwards so that the space beans reach the upper part of the fish line hole on the D-shaped ring to enable the fishing device to be in a standby state, and the connection of the sub-line in the form and the fish line hole on the D-shaped ring is indirect connection; when the buoy is arranged in the form and the main line and the sub line are penetrated and connected in the way, the fished water depth can be adjusted at will by moving the space beans, and the way has the other advantage that the prompting rod can be arranged on the sliding pipe, and has the defects of complex line group connection and complex operation.

When the straight-through connection of the line group is carried out when the buoy is connected to the main line, the wire passing ring is only arranged at the upper part of the supporting rod, and the wire passing hole is not required to be arranged on the buoy.

The above four line set connection methods are basically the same in installation operation of the trigger device of the fishing device during fishing, and are different only in that if there is a backstop, the D-shaped ring arm is rotated toward the support rod side until the D-shaped ring is blocked by the backstop, and if there is no backstop, the D-shaped ring arm is rotated toward the support rod side until the intersection angle of the D-shaped ring and the longitudinal axis of the support rod is approximately right-angled visually.

When the support rod is flat or rectangular and the lower part of the support rod is provided with 1 or 2 step-shaped support surfaces and the buoy is connected with the upper part of the support rod, a prompt rod is installed and used for prompting whether the fishing device is triggered or not to an angler, the middle section of the prompt rod is in a long and thin strip shape, the lower end of the prompt rod is connected with the upper part of the sliding tube or the lower part of the tension spring, then the prompt rod upwards passes through a prompt rod ring at the upper part of the support rod or a prompt rod hole in the buoy connected with the upper part of the support rod, the upper end of the prompt rod can be a circle and is used for dyeing or binding a more striking cloth strip or plastic film, the total length of the prompt rod is greater than the distance from the connection position of the prompt rod and the upper part of the sliding tube or the lower part of the tension spring to the surface of the upper end of the buoy connected with the upper part of the support rod when, so that the fisherman can judge whether the fishing device is triggered or not in time according to the height state of the observation prompt rod.

The scheme has the advantages that: the fishing device is triggered by means of a lever and rolling mode, has the advantages of small required trigger force, reliable and stable performance, no blockage, convenience in installation, lower manufacturing cost and capability of randomly adjusting the length of a water line, can further optimize and realize that after the fishing device is thrown into water, a fisher can judge whether the fishing device is triggered according to the height state of the prompting rod, can temporarily lock the fishing device to prevent false triggering of the fishing device when the fishing device is thrown vigorously and remotely, and has the advantages of straight-through line group connection and difficulty in line disorder.

In the embodiment, the buoy 21 is connected with the upper part of the support rod 1, the main line penetrates through the line passing hole 22 in the buoy 21 from top to bottom, then continuously penetrates through the fish line hole 16 in the D-shaped ring 13 from bottom to top, is connected with the pendant and then is connected with the sub line 31, and the main line above the fish line hole 16 is threaded with the space beans with proper size. In the figure, the reserved placing hole 6 of the thread passing ring at the upper end of the support rod 1 is used for the long and thin shape of the float, when the float is in the long and thin shape, the thread passing hole 22 on the float is not arranged on the float 21, but the main thread passes through the thread passing ring at the upper end of the middle piece from top to bottom and then passes through the fish thread hole 16 on the D-shaped ring. The main line bolt hole 7 in the figure is used for connecting the float with the main line above the upper end of the support rod 1, and is shown in figure 1. The tension spring 23 connects the support rod 1 with the slide tube 8; the slide pipe 8 is connected with a D-shaped ring 13; the slide pipe is provided with a prompt rod 25; the prompting rod hole 35 is a hole connected to the buoy at the upper part of the supporting rod 1 and is used for the prompting rod to pass through; and 26 is the upper end of the cue stick. The figure shows the support surface 2 and the extensions 3 of the support rods 1 and the film holes 4.

In fig. 24, there is shown a backstop. The function of the backstop is to limit the movement of the D-shaped ring 13, so that the D-shaped ring cannot be excessively reversely rotated, namely cannot excessively move upwards, and the triggering mechanism is in an optimal and sensitive state to be triggered after being installed and thrown; the backstop of the embodiment is formed by a round wire which passes through a backstop placing hole 9 on the sliding pipe and is a strip-shaped protrusion.

There are several other embodiments of the backstop, which will be described in fig. 32, 33 and 36.

Fig. 29 is a partially enlarged view of fig. 28, further clearly showing the structure of the slide tube 8, the D-ring 13, and the ratchets 24, in which: 23-a tension spring, 8-a sliding pipe, 24-a backstop, 13-a D-shaped ring, 16-a fish wire hole, 14-a ring arm, 1-a supporting rod, 19-an end of a straight-going part of the D-shaped ring and 25-a prompting rod.

Fig. 30 is an enlarged view of a portion of fig. 28 from another perspective, in which the middle portion of the straight portion of the D-shaped ring 13 is a cylinder 27, the cylinder 27 is rotatably hinged to the slide 8, but the two ends of the cylinder, i.e., the ends 19 of the straight portion of the D-shaped ring 13, are fixedly connected to the ring arms 14, so that the cylinder 27 can rotate with the rotation of the D-shaped ring 13.

FIG. 31 is an outline view of the embodiment assembled and with the trigger device installed in a primed state.

The upper end of the main line 28 is connected with a fishing rod; the main line 28 is provided with a space bean 29 with the outer diameter smaller than the diameter of the thread through hole 22 on the float and larger than the diameter of the fish-line hole 6 on the D-shaped ring 13; the main line goes downwards to pass through the line passing hole 22 in the float 21 and pass through the fish line hole 6 on the D-shaped ring, a weight 30 with the outer diameter larger than the aperture of the fish line hole 6 is arranged on the main line 28 below the fish line hole 6 of the D-shaped ring, then the main line 28 is connected with a sub line 31, and the tail end of the sub line 31 is connected with a fish hook.

Since the float is mounted on the support bar 1, the present embodiment is provided with the cue bars 25, 26 as the upper ends of the cue bars. And 35 is a prompting rod hole connected to the float at the upper part of the supporting rod for the prompting rod to pass through.

If the float is connected to the main line 28, it is not necessary to install a cue stick, since installation is also meaningless. If the float is connected with the main line 28, the outer diameter of the space bean 29 is larger than the diameter of the main line wire ring or hole on the float or the float seat, so that the fishing depth can be effectively adjusted, and meanwhile, if the float is connected with the main line 28, the sinker 30 is not necessary, as can be seen in fig. 1.

FIG. 32: this figure is a partial enlarged view of fig. 31 showing slide tube 8, D-ring 13, backstop 24 on slide tube 8, connection of tension spring 23 and slide tube 8, lower portion of cue bar 25, extension section 3 of support bar 1, and D-ring extension section 17 of D-ring 13 in an enlarged scale.

There is also described another embodiment of the backstop, which is an extension backstop 37 called a D-ring arm formed at an extension of the D-ring arm obliquely upward toward the B side of the support rod as shown by a dotted line in this figure,

when the D-shaped ring 13 is thrown, the oblique upward extension of the D-shaped ring 13 will lean against the support rod 1 or the tension spring 23, so that the D-shaped ring 13 is prevented from excessively reversely rotating and cannot be thrown. Such backstops formed by the obliquely upward extension of the arms of the D-rings toward the B-side of the support bar may be formed by only one piece on either the left or right side of the D-rings, by one piece on both the left and right sides of the D-rings, or by one piece on both the left and right sides of the D-rings and connected to each other (see backstop 37 on the extension of the arms of the D-rings in fig. 36).

FIG. 33: this view is an enlarged partial isometric view of the other perspective of fig. 31, when the trigger device is mounted in the armed state just before fishing, and when the cylinder 27 with the straight portion of the D-ring 13 inside the slide 8 is placed on the support surface 2 of the support rod 1, the cylinder 27 will roll away from the support surface 2 to trigger the fishing device when the fishing device is submerged and the fish eats the bait retractor. As the support surface 2 of the support rod 1 in this figure is hidden by the slide tube and not shown, please refer to fig. 1.

The length of the extension 3 of the support bar 1, the length of the D-ring extension 17 of the D-ring 13, may be slightly longer than the D-ring 13 as in the present embodiment, in yet another form, the length of the extension 3 of the support rod 1, the length of the extension 17 of the D-ring 13, is shorter than the D-ring 13, for example, the length of the extension 3 of the support bar 1 and the length of the extension 17 of the D-shaped ring 13, if shown by the dashed lines on the extension 3 of the support bar 1 and the extension 17 of the D-shaped ring 13, then in this case by providing a cross bar 33 between the two arms of the D-shaped ring 13, as shown by the dashed lines, the cross bar 33 can rest on the short extension 3 of the support bar 1, as shown by the dashed lines, so that the D-shaped ring 13 cannot fall to the side A of the support bar 1, and the cylinder 27 in the slide tube 8 is backed as it is, all the normal functions of the extension 3 of the support bar 1 and of the extension 17 of the D-ring 13 are likewise ensured in this way.

Similar to the arrangement of the D-ring arm extension backstop 37 in fig. 32, the arrow in this figure shows that a D-ring straight section extension backstop 42 formed by an extension of the straight section of the D-ring obliquely upward along the arrow path can also be arranged.

FIG. 34 is a view showing the shape and position of a film for a temporal locking fishing tackle. FIG. 18-temporary locking membrane; 1-a support bar; 3-support rod extension; 17-a D-ring extension; a 13-D ring; the film 18 is fastened on the film fastening hole 4 of the extension section 3 of the support rod 1.

FIG. 35 is a view showing a state where the fishing reel has been temporarily locked by a film. Although there is a suppression effect on the false triggering of the fishing tackle during the casting process when the fishing line is connected in a straight-through manner, the false triggering cannot be completely avoided, and the false triggering of the fishing tackle during the casting process is more likely to occur when the fishing line is connected in a manner other than the straight-through manner. Because the hook, bait and weight of the fishing device are bound to precede the fishing device itself during throwing due to the impact and inertia of the fishing device when throwing and when the fishing device is put into water, it is necessary to temporarily lock the trigger device of the fishing device before the fishing device is thrown when the trigger device of the fishing device is in a sensitive state unless the fishing device is thrown at a very close distance for fishing and when the fishing device is thrown at a longer distance for fishing. This embodiment is designed to accommodate this need. Before throwing, the extension 3 of the support rod 1 and the D-shaped ring extension 17 of the D-shaped ring 13 are wrapped together by a film 18 which is wetted by water, and because the extension 17 of the D-shaped ring 13 and the D-shaped ring are in a fixed integral structure, the movement of the extension 17 of the D-shaped ring 13 is forbidden, namely the movement of the D-shaped ring 13 is forbidden at the same time, and the trigger device is temporarily locked; after the fishing device is thrown into the water, the film 18 will automatically release quickly to unlock the trigger device by the impact and the shaking of the fishing device.

The 5 th embodiment (containing fig. 36) is an embodiment of the D-ring arm extension backstop:

fig. 36 is a view showing the shape of the D-ring and the backstop for the extension on the arm of the D-ring, and illustrates that such backstop 37 is formed by joining and fusing the two-piece extensions of the left and right arms 14 of the D-ring 13 toward the B-side of the support bar 1, and is integrally connected to the D-ring 13. In the figure: a 16-fish-line hole, a 19-D ring straight portion end, a 27-D ring straight portion cylinder, and a 17-D ring extension (which refers to a downward extension).
