Description

Technical Field

[0001] This invention relates to a line-laying bucket for construction sites, belonging to the field of construction technology. Background Technology

[0002] In building construction, auxiliary lines are needed to leave marks on the walls to assist in the construction process, which requires a large number of chalk lines. For example, chalk lines are needed to improve the quality of the reinforcing steel bars on the slab surface, ensure that the spacing of the reinforcing bars on the slab surface is consistent, or ensure that the top of the brick wall is level after the construction is completed.

[0003] Existing wire-laying hoppers mostly use a wire roller to wind the wire onto the wire-laying hopper, and use a cartridge-type wire-laying hopper cavity to color the surface of the pulled-out construction line. When using it, one person holds the wire-laying hopper and is positioned on one side of the wall, while another person pulls out the wire end from the hopper and is positioned on the other side of the wall. After the line is pulled flat, one of the people flicks the line in the opposite direction of the wall. After being flicked, the wire bundle will return to the wall due to inertia, leaving a mark on the wall. The wall is built according to the horizontal mark trajectory to ensure the construction quality.

[0004] However, existing chalk lines cannot be selected according to the desired line width in actual use. In some construction situations with rough surfaces, the auxiliary lines can only be drawn by repeatedly drawing lines or changing chalk lines with different line types, which seriously affects the construction efficiency. Furthermore, when the lines are collected after drawing, many impurities will stick to the ink lines. With continuous use, the ink lines will gradually lose their color, resulting in poor chalk line effect. Therefore, improvements are urgently needed.

[0005] Chinese utility model patent with publication number CN215701635U discloses a construction site chalk line marker applied in the field of construction site technology. The construction site chalk line marker includes a plate, a positioning component on the plate, a chalk line through hole on the positioning component, a line wheel on the plate, a rotating rod passing through the line wheel, an L-shaped handle at one end of the rotating rod, and a limiting head at the end of the line passing through the chalk line through hole.

[0006] The above-mentioned reference example can only achieve elasticity with a single line type, which has great limitations and lacks the ability to clean up the elastic lines. After repeated use, the elastic lines will become less noticeable, so improvements are urgently needed. Summary of the Invention

[0007] In order to overcome the shortcomings of existing line-laying buckets, such as limited line types, poor applicability, and inability to clean the line, this invention designs a line-laying bucket for construction sites. It can select different line types as needed, and has good line-laying effect and strong applicability.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A line-laying hopper for construction sites includes a hollow body. Inside the body is a rotary adjustment mechanism connected to several ink ropes with progressively increasing diameters. The top of the body has a limiting mechanism and an ink-dyeing mechanism for applying ink to the ink ropes. The limiting mechanism includes the same number of limiting units as the ink ropes, spaced apart along the width of the body. Each limiting unit includes a locking frame and an elastically movable reset component. A locking rod is fixed to the front end of the elastic reset component, and each ink rope is slidably connected to a corresponding locking rod. The top of the locking frame has a slot adapted to the locking rod, and the locking rod is movably locked within the slot. The rotary adjustment mechanism is connected to the same number of pull ropes as the ink ropes, each pull rope corresponding to a corresponding elastic reset component and used to tighten or loosen the elastic reset component. A control button is located on the side of the body to control the movement of the rotary adjustment mechanism, thereby causing each pull rope to sequentially loosen the elastic reset component.

[0010] Furthermore, the rotary adjustment mechanism includes a rotary unit, a drive mechanism for driving the rotary unit to rotate, and a double-panel fixed inside the machine body. The rotary unit and the drive mechanism are respectively disposed on both sides of the double-panel. The rotary unit includes a rotary rod, which includes a center block rotatably mounted at the center of the double-panel and a number of support rods evenly fixed circumferentially on the side of the center block, the same number as the ink rope. A sliding disc is disposed between any two adjacent support rods, and each sliding disc is circumferentially slidably connected to the double-panel. An extension shaft is vertically fixedly connected to the side of each sliding disc away from the double-panel. A rotating plate is rotatably sleeved on the extension shaft, and the pull rope is fixedly connected to the rotating plate. An installation groove is also provided on the extension shaft, and a spring is rotatably sleeved in the installation groove. The ink rope is fixedly connected to the spring.

[0011] Furthermore, the driving mechanism includes a one-way rotation mechanism, which comprises a clamping plate, a hook, a circular convex disc, and a driving component. A connecting shaft is fixedly sleeved at the center of the clamping plate. The connecting shaft rotatably passes through the double-sided panel and is fixedly connected to the center block. The clamping plate has a number of circumferentially evenly distributed limiting grooves, the same number as the sliding disc. The circular convex disc is disposed on one side of the clamping plate and rotatably connected to the double-sided panel. A flange is integrally formed on the side of the circular convex disc. A fixing block is disposed on the side of the circular convex disc away from the double-sided panel, and the fixing block is flush with the inner wall of the machine body. Fixed connection; one end of the hook is rotatably connected to an adapter block, which is fixedly connected to the inner wall of the machine body. The other end of the hook is integrally provided with a hook part, which is unidirectionally engaged with the limiting groove. A flange is provided on the side of the hook near the circular convex plate. The flange is slidably fitted to the side arc surface of the circular convex plate. A connecting post is integrally provided on the hook, and a return spring is fixedly connected to the connecting post. The free end of the return spring is fixedly connected to the fixing block. The driving component is respectively connected to the card plate and the circular convex plate for transmission, and the driving component is electrically connected to the control button.

[0012] Furthermore, the ink dyeing mechanism includes an operating table fixed to the top of the machine body. The operating table is hollow inside, and a groove is provided in the middle of the top of the operating table. Both sides of the groove are movably provided with docking plates. The opposite sides of the two docking plates are detachably connected with ink dyeing stickers for dyeing ink ropes. The operating table is provided with a separation and joining mechanism for driving the two docking plates to stick together or separate.

[0013] Furthermore, the splitting and engaging mechanism includes a drive motor, the output end of which is connected to a second bevel gear. The second bevel gear meshes with two first bevel gears, both of which are rotatably mounted inside the operating table. The two first bevel gears are respectively located on both sides of the groove. An adjusting screw is fixedly sleeved in the middle of each of the two first bevel gears. One end of the adjusting screw is threaded through the side wall of the groove and rotatably connected to the docking plate. The docking plate is slidably connected to the bottom of the groove.

[0014] Furthermore, an ink wiping assembly is provided on the side of the groove near the limiting mechanism. The ink wiping assembly includes mounting plates fixed on the inner walls of both sides of the groove. Push rods are vertically fixedly connected to the opposite sides of the two mounting plates. An ink wiping plate is slidably connected to the free end of each push rod. A compression spring is sleeved on the push rod. One end of the compression spring is fixedly connected to the mounting plate, and the other end is fixedly connected to the ink wiping plate. An ink wiping pad is provided on the side of the two ink wiping plates that are in contact with each other.

[0015] Furthermore, the elastic reset assembly includes a U-shaped slide, sleeve rods fixed at both ends of the U-shaped slide, and connecting springs sleeved on the sleeve rods. Each sleeve rod is vertically fixed to the top of the machine body, and one end of the connecting spring is fixedly connected to the machine body.

[0016] Furthermore, two limiting sleeves are fixedly installed inside the operating table. The free ends of the two limiting sleeves are respectively rotatably connected to the two first bevel gears, and the inner end of the adjusting screw extends out of the first bevel gear and is slidably installed inside the limiting sleeve.

[0017] Furthermore, a threaded insertion hole is provided transversely through the top of the snap-fit ​​bracket, and a limit bolt is detachably connected to the threaded insertion hole.

[0018] Furthermore, each of the aforementioned levers is movably fitted with a ring, and each ink rope is connected to each ring in a corresponding manner.

[0019] Compared with the prior art, the present invention has the following features and beneficial effects:

[0020] 1. This invention, by setting up a rotary adjustment mechanism and controlling the movement of the rotary adjustment mechanism via a control button, causes each pull rope to release the elastic reset component in sequence. This allows the elastic reset components to move up and down elastically. Since the front end of the elastic reset component is fixed with a locking rod, which is movably locked in a slot at the top of the locking frame, the locking rod can be moved out of or into the slot during the up and down elastic movement of the elastic reset component. A ring is slidably set on the locking rod. After the locking rod leaves the slot, the ring can slide out of the locking rod, allowing the ink rope connected to the ring to be used. Other ink ropes, because the elastic reset components are still taut, cannot allow the ring corresponding to the taut elastic reset component to disengage from the locking rod. This allows for the selection of ink ropes of different thicknesses. Therefore, when dealing with a relatively rough marking surface, only the control button needs to be pressed to select the appropriate ink rope, eliminating the need for frequent ink rope changes, making it convenient, quick, and effectively improving construction efficiency.

[0021] 2. In use, the ink rope is placed in the groove. The disassembly and reassembly mechanism drives the docking plates to stick together, thereby adding ink to the ink rope. Furthermore, the detachable ink-dyeing sticker allows for re-inking if the ink is insufficient, ensuring that the ink rope can mark complete and clear lines. The groove facilitates the placement of the ink rope and makes it easy to add ink to it.

[0022] 3. In this invention, in order to prevent excessive ink on the ink rope, the ink wiping plate is pressed by a compression spring, and then the ink rope is squeezed by the ink wiping plate to squeeze out and wipe away the ink. At the same time, the setting of the ink wiping plate can remove impurities from the ink rope through squeezing and friction, thereby ensuring the cleanliness of the ink rope, ensuring the convenience of use, and effectively avoiding the disadvantage of not being able to produce a clear ink line.

[0023] 4. The present invention uses the design of the main body to achieve the function of installation and fixation. In conjunction with the setting of the dispensing mechanism, the limiting mechanism, the ink dyeing mechanism and the ink wiping component, the components work together to select ink lines of different thicknesses, thereby solving the problem of frequent ink line replacement required by traditional ink fountains. Furthermore, the setting of the ink dyeing mechanism and the ink wiping component makes it easy to dye or wipe the ink line and remove impurities, further improving the applicability of the device and making it suitable for promotion and use.

Detailed Implementation

[0037] The present invention will now be described in more detail with reference to the embodiments.

[0038] Example 1

[0039] Please see Figure 1 and Figure 2 A wire-laying hopper for construction sites includes a hollow body 1, a rotary adjustment mechanism 4 inside the body 1, four ink ropes 5 with progressively increasing diameters connected to the rotary adjustment mechanism 4, and a limit mechanism 2 and an ink-dyeing mechanism 3 for dyeing the ink ropes 5 at the top of the body 1.

[0040] The limiting mechanism 2 includes four limiting units, which are arranged at intervals along the width of the machine body 1. Each limiting unit includes a locking frame 203 and an elastic reset component that can move up and down elastically. A locking rod 204 is fixed at the front end of the elastic reset component. Each ink rope 5 is slidably connected to each locking rod 204 in a corresponding manner. The top of the locking frame 203 is provided with a locking groove 2031 that is adapted to the locking rod 204. The locking rod 204 is movably locked in the locking groove 2031.

[0041] The rotary adjustment mechanism 4 is connected to the same number of pull ropes 206 as the ink rope 5. Each pull rope 206 is connected to each elastic reset component in a corresponding manner and is used to tighten or loosen the elastic reset component.

[0042] In this embodiment, a cable outlet 101 is provided at the top of the body 1. The cable outlet 101 is arranged along the width direction of the body 1. The ink rope 5 and the pull rope 206 extend outward after extending out of the cable outlet 101.

[0043] The side of the machine body 1 is provided with a control button 102 for controlling the movement of the rotary adjustment mechanism 4, thereby driving each pull rope 206 to release the elastic reset component in sequence;

[0044] Furthermore, each lever 204 is movably fitted with a ring 205, and each ink rope 5 is connected to each ring 205 in a corresponding manner.

[0045] As can be seen from the above description, the beneficial effects of the present invention are as follows: By setting a rotary adjustment mechanism 4 and controlling the movement of the rotary adjustment mechanism 4 through the control button 102, the present invention drives each pull rope 206 to release the elastic reset component in sequence, so that each elastic reset component can be released in sequence, thereby causing the elastic reset component to move up and down elastically. Since the front end of the elastic reset component is fixed with a locking rod 204, and the locking rod 204 is movably locked in the locking groove 2031 set at the top of the locking frame 203, the locking rod 204 can be driven to leave or enter the locking groove 2031 during the up and down elastic movement of the elastic reset component. 4. A ring 205 is slidably provided on the upper part. After the locking rod 204 leaves the locking slot 2031, the ring 205 can slide out of the locking rod 204, so that the ink rope 5 connected to the ring 205 can be used. Other ink ropes 5 cannot be dislodged from the locking rod 204 because the elastic reset component is still tightened. This serves to select ink ropes 5 of different thicknesses. When facing a relatively rough marking surface, you only need to press the control button 102 to select the appropriate ink rope 5. There is no need to frequently change the ink rope 5, which is convenient and quick and effectively improves the construction efficiency.

[0046] The rotary adjustment mechanism 4 is designed to select the ink rope 5. By controlling the button 102, it can be electrically controlled, which can further improve the selection efficiency.

[0047] Furthermore, a threaded insertion hole 2032 is provided transversely through the top of the snap-fit ​​bracket 203, and the threaded insertion hole 2032 is detachably connected to a limit bolt 208.

[0048] As can be seen from the above description, when not in use, the opening at the top of the slot 2031 can be locked by screwing the limit bolt 208 into the threaded insertion hole 2032 after the locking rod 204 is inserted into the slot 2031, thereby preventing the ring 205 from coming out.

[0049] Furthermore, the elastic reset assembly includes a U-shaped slide 201, sleeve rods 207 fixed at both ends of the U-shaped slide 201, and a connecting spring 202 sleeved on the sleeve rods 207. Each sleeve rod 207 is vertically fixed to the top of the body 1, and one end of the connecting spring 202 is fixedly connected to the body 1.

[0050] As can be seen from the above description, the pull rope 206 pulls the U-shaped slide 201. During the descent of the U-shaped slide 201, the connecting spring 202 is compressed. Then, the elastic potential energy stored in the connecting spring 202 drives the U-shaped slide 201 to rise when the pull rope 206 releases the U-shaped slide 201, thereby driving the locking rod 204 to exit the locking slot 2031. This is convenient, quick, simple and reliable.

[0051] Example 2

[0052] A line-laying hopper for construction sites, based on the above-described embodiment one, further defines the overall mechanical connection relationship of the adjusting mechanism 4 as follows:

[0053] Please see Figures 3 to 9 The adjustment mechanism 4 includes a turning unit, a drive mechanism for driving the turning unit to rotate, and a double-panel 401 fixed inside the body 1. The turning unit and the drive mechanism are respectively arranged on both sides of the double-panel 401. The turning unit includes a turning rod 402, which includes a center block 4021 rotatably mounted at the center of the double-panel 401 and four support rods 4022 evenly fixed to the sides of the center block 4021 along the circumference. A sliding disk 403 is arranged between any two adjacent support rods 4022. All sliding disks 403 are circumferentially slidably connected to the double-sided panel 401; each sliding disk 403 has an extension shaft 404 vertically fixedly connected to the side away from the double-sided panel 401, a rotating plate 405 is rotatably sleeved on the extension shaft 404, the pull rope 206 is fixedly connected to the rotating plate 405, the extension shaft 404 is also provided with an installation groove 406, a spring is rotatably sleeved in the installation groove 406, the ink rope 5 is fixedly connected to the spring, the spring spring facilitates the recovery of the ink rope 5 after it is pulled out and the work is completed.

[0054] Specifically, the double panel 401 has an annular adjustment groove 4011 on its side, and the sliding disk 403 has a slider on the side near the double panel 401. The slider is slidably locked in the adjustment groove 4011 and can slide circumferentially in the adjustment groove 4011 to adjust the position of the extension shaft 404.

[0055] The double-panel 401 is fixed to the inner wall of the body 1 by three connecting rods 413.

[0056] As described above, the double-sided panel 401 serves as the mounting mechanism, and the drive mechanism rotates the lever 402. During rotation, the lever 402 causes the sliding disk 403 to slide along the annular adjustment groove 4011, thus adjusting the position of the sliding disk 403. Since a pull rope 206 is provided on the extension shaft 404 fixed to the sliding disk 403, a cycle is formed during the position adjustment of the sliding disk 403, moving it from near the outlet 101 to away from the outlet 101. When the extension shaft 404 approaches the outlet... When the line outlet 101 is open, the distance between the pull rope 206 and the elastic reset component is closest, and the elastic reset component is released. As a result, the ink rope 5, which is fixed on the same extension shaft 404 as the pull rope 206, is released, and the ink rope 5 can be selected, thus playing a selection role. By continuously adjusting the position of the sliding disk 403, by adjusting one of the four sliding disks 403 to be close to the line outlet 101, and in conjunction with the limiting mechanism 2, the adjustment is achieved. The adjustment process is convenient and quick, solving the shortcomings of traditional ink fountains that cannot select ink ropes 5 of different thicknesses.

[0057] Please see Figure 8 In this embodiment, in order to ensure that the pull rope 206 and the ink rope 5 are positioned directly below the corresponding elastic reset components, the four extension shafts 404 are arranged to increase in length sequentially along the circumferential direction. The rotating plate 405 and the mounting groove 406 are both located near the end of the extension shafts 404. This makes the connection length of the pull rope 206 and the ink rope 5 more reasonable and can effectively prevent the pull rope 206 and the ink rope 5 from tangling and knotting, thereby improving the applicability of the device.

[0058] Furthermore, the driving mechanism includes a one-way rotation mechanism, which includes a locking plate 407, a hook 409, a circular convex plate 410, and a driving component. A connecting shaft is fixedly sleeved at the center of the locking plate 407. After the connecting shaft rotates through the double-sided panel 401, it is fixedly connected to the center block 4021. The side of the locking plate 407 is evenly provided with the same number of limiting grooves 408 as the sliding plate 403 along the circumferential direction.

[0059] A circular convex disc 410 is disposed on one side of the card plate 407 and is rotatably connected to the double panel 401. A flange 4101 is integrally provided on the side of the circular convex disc 410. A fixing block 411 is provided on the side of the circular convex disc 410 away from the double panel 401. The fixing block 411 is fixedly connected to the inner wall of the machine body 1.

[0060] One end of the hook 409 is rotatably connected to the adapter block 4092, which is fixedly connected to the inner wall of the machine body 1. The other end of the hook 409 is integrally provided with a hook part, which is unidirectionally engaged with the limiting groove 408. A flange 4091 is provided on the side of the hook 409 near the circular convex plate 410. The flange 4091 slides against the side arc surface of the circular convex plate 410. A connecting post 4093 is integrally provided on the hook 409. A return spring 412 is fixedly connected to the connecting post 4093. The free end of the return spring 412 is fixedly connected to the fixing block 411.

[0061] The drive unit is connected to the card plate 407 and the circular cam 410 respectively, and is electrically connected to the control button 102.

[0062] As described above, the drive unit is controlled by the control button 102. The drive unit first drives the circular cam 410 to rotate. During the rotation of the circular cam 410, the second flange 4101 also rotates synchronously. When the second flange 4101 passes the first flange 4091, it will lift the first flange 4091, thereby causing the hook 409 to rotate around the adapter block 4092. This causes the hook part of the hook 409 to release the limiting groove 408, and the locking plate 407 loses its limiting function. Then the drive unit drives the locking plate 409 to rotate. When the 07 rotates, the card plate 407 rotates, which drives the lever 402 to rotate, thereby adjusting the position of the sliding disk 403. When the second flange 4101 leaves the first flange 4091, the hook 409 will be pulled tight by the return spring 412 and continue to fit against the first flange 4091, facilitating the next switch. The hook 409 is designed to limit the card plate 407 in one direction, preventing the card plate 407 from rotating due to inertia during switching and ensuring stability during use.

[0063] Example 3

[0064] A line-laying hopper for construction sites, based on the above-described Embodiment 1 or Embodiment 2, further defines the overall mechanical connection relationship of the ink-dyeing mechanism 3 as follows:

[0065] As can be seen from the above description, the ink dyeing mechanism 3 includes an operating table 301 fixed to the top of the machine body 1. The operating table 301 is hollow inside, and a groove 302 is provided in the middle of the top of the operating table 301. A docking plate 303 is movably provided on both sides of the groove 302. The opposite sides of the two docking plates 303 can be detachably connected to an ink dyeing sticker 308 for dyeing the ink rope 5. The operating table 301 is provided with a separation and joining mechanism for driving the two docking plates 303 to stick together or separate.

[0066] As can be seen from the above description, when in use, the ink rope 5 is placed in the groove 302, and the disassembly and reassembly mechanism drives the docking plates 303 to stick together to add ink to the ink rope 5. Furthermore, with the detachable ink-dyeing sticker 308, if the ink is insufficient, the ink-dyeing sticker 308 can be replaced to re-ink the ink, ensuring that the ink rope 5 can mark complete and clear lines. For the purpose of promotion and use, Velcro can be used.

[0067] The groove 302 is designed to facilitate the placement of the ink rope 5, thereby making it easier to add ink to the ink rope 5.

[0068] Furthermore, the splitting and engaging mechanism includes a drive motor 309, the output end of which is connected to a second bevel gear 307. The second bevel gear 307 is meshed with two first bevel gears 306. Both first bevel gears 306 are rotatably mounted inside the operating table 301, and are respectively located on both sides of the groove 302. An adjusting screw 304 is fixedly sleeved in the middle of each of the two first bevel gears 306. One end of the adjusting screw 304 is threaded through the side wall of the groove 302 and rotatably connected to the docking plate 303. The docking plate 303 is slidably connected to the bottom of the groove 302.

[0069] Specifically, the drive motor 309 is started by control button 102.

[0070] As described above, the drive motor 309 starts and drives the second bevel gear 307 to rotate. The rotation of the second bevel gear 307 drives the two first bevel gears 306 to rotate. During the rotation of the first bevel gears 306, the adjusting screw 304 is driven to rotate, thereby causing the adjusting screw 304 to move laterally under the action of the thread. This causes the mating plates 303 fixed at the end of the adjusting screw 304 to fit together, and the mating plates 303 are slidably connected to the bottom wall of the groove 302, which can ensure the stability of the mating plates 303 during the sliding process.

[0071] Furthermore, an ink wiping assembly 6 is also provided on the side of the groove 302 near the limiting mechanism 2. The ink wiping assembly 6 includes mounting plates 603 fixed on the inner walls of both sides of the groove 302. Push rods 604 are vertically fixedly connected to the opposite sides of the two mounting plates 603. Each push rod 604 has an ink wiping plate 601 slidably connected to its free end. A compression spring 602 is sleeved on the push rod 604. One end of the compression spring 602 is fixedly connected to the mounting plate 603, and the other end is fixedly connected to the ink wiping plate 601. An ink wiping sheet 605 is provided on the side of the two ink wiping plates 601 that are in contact with each other.

[0072] As can be seen from the above description, during the ink rope 5 recycling process, in order to prevent excessive ink on the ink rope 5, the ink wiping plate 601 is pressed by the compression spring 602. Then, the ink wiping plate 605 can squeeze the ink rope 5 to squeeze out and wipe away the ink. At the same time, through the setting of the ink wiping plate 605, impurities on the ink rope 5 can be wiped away by squeezing and friction, thereby ensuring the cleanliness of the ink rope 5, ensuring the convenience of use, and effectively avoiding the disadvantage of not being able to eject clear ink lines.

[0073] Furthermore, two limiting sleeves 305 are fixedly installed inside the operating table 301. The free ends of the two limiting sleeves 305 are respectively rotatably connected to the two first bevel gears 306, and the inner end of the adjusting screw 304 extends out of the first bevel gears 306 and is slidably installed inside the limiting sleeves 305.

[0074] As can be seen from the above description, the setting of the limit sleeve 305 can ensure the stability of the adjusting screw 304 during the movement process, and is suitable for promotion and use.

[0075] The working principle of this invention is as follows: First, the control button 102 is activated, causing the rotary adjustment mechanism 4 to drive the pull rope 206 to move. When the ink rope 5 that needs to be used is released, the rotary adjustment mechanism 4 stops moving. Then, the ring 205 is disengaged from the latch 204, and the ink rope 5 is placed in the groove 302, so that the ink rope 5 is positioned between the two ink wiping plates 605 and between the two mating plates 303. The drive motor 309 is activated to drive the two adjusting screws 304 to move relative to each other, thereby causing the mating plates 303 to fit together. Squeeze the ink rope 5 to add ink, and then pull the ink rope 5 to the appropriate length to snap the line. After the snap is complete, the ink rope 5 is retracted by the action of the spring. During the retraction process, the ink rope 5 is wiped off with excess ink and impurities by the action of the two ink wiping plates 605, ensuring that the ink rope 5 is clean and tidy. Finally, put the ring body 205 back onto the locking rod 204, and then lock the locking rod 204 into the locking groove 2031. After completing all the work, screw the limiting bolt 208 into the threaded insertion hole 2032.
