Description

A suspended conveyor device for cutting and conveying poultry and livestock meat. Technical Field

[0001] This invention relates to the field of livestock slaughtering and processing technology, specifically to a hanging conveyor device for cutting and transporting poultry and livestock meat. Background Technology

[0002] In the poultry and livestock meat processing industry, overhead conveyor systems are key equipment in production lines, used to transport slaughtered carcasses or cut meat pieces to various processing stations. Currently, common overhead conveyor devices mostly use fixed hooks or simple movable hooks. With fixed hooks, manual removal of meat pieces from the hooks is usually required during unloading, which is labor-intensive, inefficient, and poses safety hazards on busy production lines. While some devices have automatic unhooking functions, the unhooking action is unreliable and prone to failure due to meat pieces getting stuck, requiring manual intervention, which also affects the automation level and efficiency of the production line.

[0003] Furthermore, for smaller or firmer poultry (such as pigeons and quails), the friction between the meat and the hook is greater, making it more prone to sticking during unhooking. This results in incomplete removal and may even require manual assistance, further increasing the risk of cross-contamination and reducing production efficiency. Therefore, there is an urgent need for an automatic suspended conveyor device that provides reliable and thorough unhooking, is adaptable to different types of poultry and livestock meat, and is simple in structure and easy to maintain. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a suspended conveying device for cutting and transporting poultry and livestock meat, which solves the problem of unreliable unhooking.

[0005] To achieve the above objectives, the present invention provides a first invention: a suspended conveying device for cutting poultry and livestock meat, comprising a chain body, and further comprising: a carrier frame, the carrier frame being arranged at equal intervals below the chain body via connecting frames; a hook body, the hook body being formed by two sets of intersecting L-shaped rods, with a central shaft rotatably mounted at the intersection point, the central shaft being fixed inside the carrier frame; an adjusting component, the adjusting component being located between the upper parts of the two sets of L-shaped rods, wherein during the conveying stage, the height of the adjusting component remains unchanged to limit the angle of the two sets of L-shaped rods, and during the unhooking stage, the adjusting component rises to reduce the angle of the two sets of L-shaped rods, thereby forming a state of inward retraction of the two sets of L-shaped rods; a thrusting component, the thrusting component being located between the lower ends of the two sets of L-shaped rods, used to prevent the meat from retracting along with the L-shaped rods when the L-shaped rods retract; an auxiliary frame, the auxiliary frame being connected to the adjusting component; and an auxiliary track, the auxiliary track being located below the chain track, the auxiliary frame sliding within the auxiliary track, and at the unloading station, the auxiliary track being provided with a rail for controlling the rising and falling of the auxiliary frame.

[0006] Furthermore, the thrust member includes a U-shaped frame, with the two sides of the middle part of the U-shaped frame suspended below the carrier by hanging rods, and the U-shaped frame is provided with a clearance groove to avoid the L-shaped rod.

[0007] Furthermore, the thrust member includes a pressure rod, one end of which is located near the lower end of the L-shaped rod and tilts downwards in the opposite direction; the free ends of the two pressure rods are blunt; the orthographic projections of the two sets of L-shaped rods along the linear direction coincide, and the orthographic projections of the two sets of pressure rods are staggered. Furthermore, the positioning assembly includes: a conical disk located between the upper parts of the two sets of L-shaped rods, and a column fixedly mounted on the upper end of the conical disk; a sliding sleeve fitted on the upper part of the L-shaped rod, with a hinged rod hinged between the sliding sleeve and the upper end of the column; and the auxiliary frame fixedly connected to the upper end of the column.

[0008] Furthermore, the positioning assembly includes: a symmetrical lead screw located on the side of the hook body near the auxiliary rail, with nuts symmetrically threaded onto the lead screw; a sliding sleeve fitted onto the upper part of the L-shaped rod, with the sliding sleeve and the nut connected by a rotating shaft; and a gear fixed on the symmetrical lead screw, with a rack plate for gear meshing fixed below the auxiliary frame.

[0009] Furthermore, the track for controlling the raising and lowering of the auxiliary frame includes a continuous lifting track, a maintaining track, and a lowering track. One end of the auxiliary frame located within the auxiliary track is confined within the auxiliary track and is equipped with rollers.

[0010] On the other hand, the present invention also provides a second invention, a poultry and livestock meat segmentation and suspension conveying device, comprising a chain body, characterized in that it further comprises: a carrier frame, the carrier frame being arranged at equal intervals below the chain body via connecting frames; a hook body, the hook body being formed by two sets of L-shaped rods crossing each other, and a central shaft being rotatably installed at the intersection point, the central shaft being fixed inside the carrier frame; an adjustment component, the adjustment component being located on both sides above the two sets of L-shaped rods, the adjustment component not moving during the conveying stage to limit the angle of the two sets of L-shaped rods, and moving during the unhooking stage to adjust the tilt angle of the L-shaped rods, so that the tilt directions of the two L-shaped rods are reversed, so that one L-shaped rod squeezes the poultry and livestock meat on the other L-shaped rod; an auxiliary frame, the auxiliary frame being connected to the adjustment component and used to control the movement of the adjustment component; an auxiliary track, the auxiliary track being located below the chain track, the auxiliary frame sliding within the auxiliary track, and at the unloading station, the auxiliary track being provided with a track for controlling the raising or lowering of the auxiliary frame.

[0011] Furthermore, the adjusting assembly includes: a sliding sleeve fitted on the upper part of the L-shaped rod; two sets of one-way lead screws distributed on both sides of the L-shaped rod, with nuts threaded onto the one-way lead screws, and the opposite nuts connected to the sliding sleeves via a rotating shaft; and a gear mounted on the one-way lead screw, with a rack plate meshing on one side of the gear, and the auxiliary frame fixed to the upper end of the rack plate.

[0012] Furthermore, the positioning assembly includes: a conical disc located between two L-shaped rods, the upper end of which is fixedly connected to an auxiliary frame, and when the auxiliary frame rises, the column is higher than the upper end of the L-shaped rods; a force-bearing rod fixed to the upper end of one of the L-shaped rods near the auxiliary track, and a push block opposite to the force-bearing rod is provided on the auxiliary track, allowing the force-bearing rod to be pushed when it passes the push block; and a first bevel gear, which has two sets, each fixedly connected to the intersection of the two L-shaped rods, with a second bevel gear meshing between the two first bevel gears, and the first bevel gear connected to the central shaft via a torsion spring.

[0013] Furthermore, the track for controlling the rise or fall of the auxiliary frame includes a lifting track, a maintaining track, and a descending track, with the push block installed below the maintaining track.

[0014] The present invention has the following beneficial effects: (1) The poultry and livestock meat cutting and hanging conveying device, by setting an auxiliary track and adjustment component linked with the conveying chain, can automatically trigger the change of the hook posture when the conveying device runs to a specific unloading station, and complete the unloading of meat pieces without manual intervention, which greatly improves the unloading efficiency, reduces labor costs and labor intensity, and the unhooking is thorough and highly reliable.

[0015] (2) The poultry and livestock meat cutting and conveying device is equipped with a thrust component (such as a U-shaped frame or a staggered pressure bar) to address the issue of firm meat that is not easy to fall off. When the hook retracts, the thrust component can effectively prevent the meat pieces from moving with the hook, generating relative displacement, thereby overcoming friction and ensuring that the meat pieces are forcibly separated. This solves the problem of sticking to the hook, has a high success rate of unhooking, and the unhooking process is controllable and gentle, avoiding damage to the meat pieces caused by rough pulling or falling, which is conducive to maintaining the good appearance of poultry and livestock meat.

[0016] (3) In this poultry and livestock meat cutting and conveying device, the unhooking is achieved entirely by utilizing the geometric relationship between the shape and movement of the hooks (L-shaped rods). When the two L-shaped rods rotate in opposite directions under the upper drive, the positions of the hooks at their lower ends will be interchanged. During this process, one hook will directly squeeze or push the meat piece suspended on the other hook along its movement trajectory, thereby "pushing" the meat piece away from the hook. The entire unhooking action does not rely on any additional, independent thrust components (such as U-shaped frames, pressure rods, etc.), but can be completed solely through the movement of the L-shaped rods themselves, greatly simplifying the redundant structure of the hook area. The structure of the hook area is simpler and more open, without complex obstructions or gaps. This is very beneficial for post-production cleaning and disinfection, effectively reducing the sanitary dead spots where microorganisms can hide, and meeting the strict hygiene standards required for food processing equipment. At the same time, the simple structure also means lower maintenance complexity.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] On the one hand, the present invention provides a first type of poultry and livestock meat cutting and hanging conveying device, as shown in Figures 1-10.

[0023] Example 1, as shown in Figures 1-3, the poultry and livestock meat cutting and hanging conveyor device provided in this example includes a racetrack-shaped chain track 1 and a chain body 2 located within the chain track 1. Below the chain body 2, a carrier frame 4 is arranged at equal intervals through a connecting frame 9. A hook body is mounted on the carrier frame 4. When the chain body 2 rotates, it drives the hook body to rotate through the connecting frame 9 and the carrier frame 4, so that it reaches the cutting work, splitting the whole poultry and livestock into two parts. Then, it reaches the unloading work, where the split poultry and livestock are unhooked from the hook body.

[0024] The hook body here is formed by the intersection of two sets of L-shaped rods 6, and a central shaft 12 is rotatably installed at the intersection point. The central shaft 12 is fixed inside the carrier frame 4. In order to maintain the required tilt angle of the two sets of L-shaped rods 6 to lift poultry meat in the conveying state, and to reduce the angle between the two sets of L-shaped rods 6 in the unloading state (i.e., the two L-shaped rods 6 retract), so as to achieve automatic unhooking, an adjustment component 7 is also provided. The adjustment component 7 is installed on the carrier frame 4 and is located between the upper parts of the two sets of L-shaped rods 6. In the conveying stage, the height of the adjustment component 7 remains unchanged to limit the angle of the two sets of L-shaped rods 6. In the unhooking stage, the adjustment component 7 rises to reduce the angle of the two sets of L-shaped rods 6, so as to form the state of the two sets of L-shaped rods 6 retracted. When the L-shaped rods 6 retract, the poultry meat can detach from the L-shaped rods 6 due to its own weight. It is preferable to set a receiving table 10 at the unloading station.

[0025] In actual operation, if the poultry is small in weight and has firm meat, the meat will not detach from the hook body due to its own weight when the L-shaped rod 6 retracts. Therefore, in this embodiment, a thrust member 5 is also provided. The thrust member 5 is located between the lower ends of the two sets of L-shaped rods 6 and is used to prevent the meat from retracting along with the L-shaped rod 6 when the L-shaped rod 6 retracts.

[0026] To ensure that the L-shaped rod 6 automatically retracts when it reaches the unloading station, an auxiliary frame 11 and an auxiliary track 3 are also provided. The auxiliary frame 11 is connected to the adjustment component 7, and the auxiliary track 3 is located below the chain track 1. The auxiliary frame 11 slides within the auxiliary track 3. At the unloading station, the auxiliary track 3 is equipped with a track for controlling the rise and fall of the auxiliary frame 11. That is, at the unloading station, the track for rising and falling can control the retraction of the L-shaped rod 6 through the auxiliary frame 11 and the adjustment component 7.

[0027] Preferably, the track used to control the rise and fall of the auxiliary frame 11 includes a continuous lifting rail 31, a holding rail 32, and a lowering rail 33. One end of the auxiliary frame 11 is located within the auxiliary rail 3. The lifting rail 31 is used to control the rise of the auxiliary frame 11. The holding rail 32 can maintain the auxiliary frame 11 at the height after being raised for a period of time, thereby ensuring complete disengagement. The lowering rail 33 is mainly used to reset the auxiliary frame 11 downwards, preparing for the next disengagement.

[0028] Preferably, a guide groove 8 for vertically guiding the auxiliary frame 11 is provided on the carrier 4, and a roller 111 is provided on the auxiliary frame 11, which moves within the auxiliary track 3.

[0029] Preferably, the L-shaped rod 6 here includes a force-bearing section 63, a connecting section 62, and a hook body 61, and the angle between the hook body 61 and the connecting section 62 can be selected as 45-90°.

[0030] Specifically, referring to Figures 3 and 4, the thrust member 5 in this embodiment includes a U-shaped frame. The two sides of the middle part of the U-shaped frame are suspended below the carrier frame 4 by the hanger rods 52. The U-shaped frame is provided with a clearance groove 53 to avoid the L-shaped rod 6. The U-shaped frame includes a horizontal plate 51 and a vertical plate 54 located above both ends of the horizontal plate 51.

[0031] In this embodiment, when the two sets of L-shaped rods 6 retract, the poultry meat is blocked by the longitudinal plate 54 and cannot retract along with the L-shaped rods 6, so the poultry meat can automatically fall off.

[0032] As shown in Figures 3 and 4, the aforementioned positioning component 7 includes a conical disc 72 and a sliding sleeve 71. The conical disc 72 is located between the upper parts of the two sets of L-shaped rods 6. Preferably, the slope angle of the conical disc 72 is the same as the tilt angle of the L-shaped rods 6 when they are hanging meat. In the state shown in Figure 4, although the hook 61 hangs the poultry meat and is subjected to the weight of the poultry meat, the L-shaped rods 6 cannot retract due to the restriction effect of the conical disc 72. When the conical disc 72 moves upward, the restriction on the retraction of the L-shaped rods 6 can be released.

[0033] Although the L-shaped rod 6 can automatically retract due to the gravity of the poultry meat after the retraction restriction is released, it cannot retract further once the poultry meat is blocked by the longitudinal plate 54. This may result in the poultry meat not completely detaching from the hook body 61. Therefore, the sliding sleeve 71 in this embodiment is used to actively control the rotation angle of the L-shaped rod 6. Even if the poultry meat is blocked by the longitudinal plate 54, the L-shaped rod 6 can still rotate actively and detach from the poultry meat.

[0034] Specifically, a column 73 is fixed to the upper end of the conical disc 72, a sliding sleeve 71 is sleeved on the upper part of the L-shaped rod 6, a hinge rod 74 is hinged between the sliding sleeve 71 and the upper end of the column 73, and the auxiliary frame 11 is fixed to the upper end of the column 73.

[0035] In this embodiment, when the auxiliary frame 11 drives the column 73 to move upward, the sliding sleeve 71 will also move upward, thereby causing the two sets of L-shaped rods 6 to retract.

[0036] Referring to Figures 9 and 10, this embodiment also provides another adjusting component 7 to replace the adjusting component 7 mentioned above. Specifically, the adjusting component 7 in this embodiment includes a symmetrical lead screw 78, a sliding sleeve 71, and a gear 76. The symmetrical lead screw 78 is located on the side of the hook body near the auxiliary rail 3. Nuts 75 are symmetrically threaded onto the symmetrical lead screw 78. The sliding sleeve 71 is sleeved on the upper part of the L-shaped rod 6. The sliding sleeve 71 and the nut 75 are connected by a rotating shaft. In the hanging and conveying state, since the distance between the two nuts 75 remains unchanged, the distance between the two sliding sleeves 71 remains unchanged, and thus it is located at the angle required for the hanging and conveying of the L-shaped rod 6. In the unloading state, the two nuts 75 move closer to each other, thereby controlling the two sliding sleeves 71 to move closer to each other. The sliding sleeves 71 drive the two sets of L-shaped rods 6 to retract.

[0037] In order to achieve the movement of nut 75, the aforementioned gear 76 is fixed on the symmetrical lead screw 78. A rack plate 77 meshing with the gear 76 is fixed below the auxiliary frame 11. When the auxiliary frame 11 descends, it can drive the rack plate 77 to move downward, thereby controlling the rotation of gear 76. The rotation of gear 76 can realize the rotation of symmetrical lead screw 78, that is, to achieve the purpose of the two nuts 75 being relatively close or relatively far apart.

[0038] Example 2, as shown in Figures 5-8, is mainly used to replace the thrust member 5 in Example 1. The thrust member 5 includes a pressure rod 56. One end of the pressure rod 56 is located near the lower end of the L-shaped rod 6 and is inclined downward in the opposite direction. The free ends of the two pressure rods 56 are blunt heads 55. The orthographic projections of the two sets of L-shaped rods 6 along the line coincide, and the orthographic projections of the two sets of pressure rods 56 are staggered along the line.

[0039] In this embodiment, when the two sets of L-shaped rods 6 retract, the pressure rods 56 at their lower ends also retract. Referring to Figure 6, for example, as the hook 61 on the left side gradually moves to the right, the pressure rod 56 on the left side also moves to the right. At this time, the pressure rod 56 on the left side will exert a rightward pushing force on the pressure rod 56 on the right side, forcing the poultry meat to detach from the hook 61 on the right side. In addition, the hook 61 on the right side also moves to the left, making the poultry meat fall off even faster.

[0040] On the other hand, referring to Figures 11-17, the present invention also provides another poultry and livestock meat segmentation hanging conveyor device. Compared with the invention described above, this poultry and livestock meat segmentation hanging conveyor device also uses cross-arranged L-shaped rods 6 as the hook body, and also disengages by retracting the L-shaped rods 6. However, the core difference is that the present invention does not require the use of a thrust member 5 to ensure disengagement. The present invention will be fully described below.

[0041] Example 1: The poultry and livestock meat cutting and hanging conveyor device includes a racetrack-shaped chain track 1 and a chain body 2 located within the chain track 1. Below the chain body 2, there are carrier frames 4 arranged at equal intervals through connecting frames 9. Hook bodies are mounted on the carrier frames 4. When the chain body 2 rotates, it drives the hook bodies to rotate through the connecting frames 9 and carrier frames 4, so that they reach the cutting station and cut the entire poultry and livestock into two parts. Then, the feeding work is carried out to unhook the cut poultry from the hook bodies.

[0042] The hook body here is formed by the intersection of two sets of L-shaped rods 6, and the central shaft 12 is rotatably installed at the intersection point. The central shaft 12 is fixed in the frame 4. In the conveying state, the two sets of L-shaped rods 6 maintain the required tilt angle to lift the poultry and livestock meat. In the unloading state, the tilt angle of the L-shaped rods 6 is adjusted so that the tilt direction of the two L-shaped rods 6 is reversed, which is called "negative angle". The "negative angle" here means that the hook body 61 originally located on the right side moves to the left side, and the hook body 61 originally on the left side moves to the right side, so that one L-shaped rod 6 squeezes the poultry and livestock meat on the other L-shaped rod 6, ensuring that the hook is completely unhooked.

[0043] Preferably, the projections of the two L-shaped rods 6 in the linear direction do not overlap, that is, they are slightly misaligned.

[0044] To achieve the above objectives, an adjustment component 7 is also provided. The adjustment component 7 is installed on the carrier 4 and located on the upper part of the two sets of L-shaped rods 6. The adjustment component 7 is located on both sides above the two sets of L-shaped rods 6. During the conveying stage, the adjustment component 7 does not operate to limit the angle of the two sets of L-shaped rods 6. During the unhooking stage, the adjustment component 7 operates to adjust the tilt angle of the L-shaped rods 6, so that the tilt direction of the two L-shaped rods 6 is reversed, so that one L-shaped rod 6 squeezes the poultry and livestock meat on the other L-shaped rod 6.

[0045] The "negative angle" rotation is a defined, forced mechanical motion. The positioning component 7 directly and precisely controls the rotation angle and final position of the L-shaped rod 6. This active and controllable drive method ensures that the unhooking action is not significantly affected by the weight, shape, or firmness of the meat. Even for small or compact pieces of meat, the forced change in the relative position between the hooks 61 generates a reliable pushing action, resulting in a high success rate and consistency in unhooking, avoiding the uncertainty caused by relying on the weight of the meat to detach.

[0046] To enable the L-shaped rod 6 to rotate automatically when it reaches the unloading station, an auxiliary frame 11 and an auxiliary track 3 are also provided. The auxiliary frame 11 is connected to the adjustment component 7 and is used to control the movement of the adjustment component 7. The auxiliary track 3 is located below the chain track 1, and the auxiliary frame 11 slides in the auxiliary track 3. At the unloading station, the auxiliary track 3 is provided with a track for controlling the rise or fall of the auxiliary frame 11.

[0047] Specifically, referring to Figures 11-15, the aforementioned adjusting assembly 7 includes a sliding sleeve 71, a one-way lead screw 79, and a gear 76. The sliding sleeve 71 is sleeved on the upper part of the L-shaped rod 6. There are two sets of one-way lead screws 79, distributed on both sides of the L-shaped rod 6. Nuts 75 are threaded onto the one-way lead screws 79. The opposite nuts 75 are connected to the sliding sleeves 71 through a rotating shaft. When the two one-way lead screws 79 rotate, the two nuts 75 move relative to each other or in opposite directions. When they move relative to each other, the two sliding sleeves 71 drive the L-shaped rod 6 to rotate, causing the two L-shaped rods 6 to contract until they reach a "negative angle".

[0048] In order to achieve the rotation of the two one-way lead screws 79, a gear 76 is provided on the one-way lead screw 79, and a rack plate 77 is meshed on one side of the gear 76. An auxiliary frame 11 is fixed on the upper end of the rack plate 77.

[0049] In this embodiment, in order to achieve stable force on the unidirectional lead screws 79 on both sides, two sets of auxiliary rails 3 can be set up, arranged as shown in Figure 11, distributed on both sides of the carrier frame 4, and the two ends of the auxiliary frame 11 slide in the two sets of auxiliary rails 3 respectively.

[0050] It should be noted that in the turning sections of the conveying path, the radius of curvature of the outer auxiliary track 3 should be greater than that of the inner auxiliary track 3.

[0051] Preferably, the track used to control the rise and fall of the auxiliary frame 11 includes a continuous lifting rail 31, a holding rail 32, and a lowering rail 33. One end of the auxiliary frame 11 is located within the auxiliary rail 3. The lifting rail 31 is used to control the rise of the auxiliary frame 11. The holding rail 32 can maintain the auxiliary frame 11 at the height after being raised for a period of time, thereby ensuring complete disengagement. The lowering rail 33 is mainly used to reset the auxiliary frame 11 downwards, preparing for the next disengagement.

[0052] Example 2, as shown in Figures 16 and 17, the adjustment component 7 of this embodiment includes a column 73, a force-bearing rod 712 and a bevel gear 710.

[0053] The conical disc 72 is located between the two L-shaped rods 6. The upper end of the conical disc 72 is fixed to the auxiliary frame 11. When the auxiliary frame 11 rises, the conical disc 72 is higher than the upper end of the L-shaped rod 6, so the conical disc 72 will not block the "negative angle" rotation of the L-shaped rod 6. The force-bearing rod 712 is fixed to the upper end of one of the L-shaped rods 6 near the auxiliary track 3. The auxiliary track 3 is provided with a push block 13 opposite to the force-bearing rod 712. Referring to FIG17, the L-shaped rod 6 with the force-bearing rod 712 should be the L-shaped rod 6 with the force-bearing section 63 on the right and the hook body 61 on the left. This L-shaped rod 6 is located behind the other L-shaped rod 6. When the force-bearing rod 712 on this L-shaped rod 6 passes the push block 13, it can be pushed, so that the L-shaped rod 6 rotates counterclockwise.

[0054] In order to achieve synchronous reverse rotation of the two L-shaped rods 6, the aforementioned bevel gear 710 is provided in two sets, which are fixedly connected to the intersection of the two L-shaped rods 6 respectively. A bevel gear 711 meshes between the two bevel gears 710, so that when one L-shaped rod 6 rotates, the other L-shaped rod 6 rotates synchronously in the opposite direction, realizing the "negative angle" change of the two L-shaped rods 6.

[0055] Preferably, the bevel gear 710 is connected to the central shaft 12 by a torsion spring, which enables the L-shaped rod 6 to automatically reset after the poultry meat is unhooked, so that the conical disc 72 can be inserted again into the two sets of L-shaped rods 6 to restrict its rotation.

[0056] Preferably, the push block 13 is installed below the holding rail 32, which means that the push block 13 only begins to push the force rod 712 after the auxiliary frame 11 has been fully raised on the lifting rail 31 to a height higher than the upper end of the L-shaped rod 6.
