Description
Technical Field
[0001] The present invention relates to the technical field of rotating shaft hinge parts transmission, and more specifically, it relates to a heat-treated rotating shaft hinge parts transmission device. Background Art
[0002] A pivot hinge is a mechanical device used to connect two objects and allow them to rotate relative to each other within a certain angle range. It is usually composed of a hinge head, a body and a base. Pivot hinges are widely used in electronic products such as laptops and foldable screen mobile phones to achieve folding of screens or covers.
[0003] In order to make the surface of the shaft hinge obtain a high hardness and improve its wear resistance, the surface of the shaft hinge needs to be heat treated, and the transmission equipment needs to transport the shaft hinge to the inside of the carburizing box to carburize the surface of the shaft hinge. When carburizing, usually, the carburizing area of the carburizing box is located in the upper position inside it. This is because the temperature distribution and atmosphere conditions in the upper area are often more suitable for the infiltration and diffusion of carbon elements, so that the carburizing effect can be achieved more effectively. Therefore, after the shaft hinge is transported to the inside of the carburizing box, it needs to be further transported upward to ensure that it can accurately reach the carburizing area of the carburizing box. In this way, the shaft hinge can be carburized under suitable temperature and atmosphere conditions, so that the carbon element can evenly penetrate its surface to form the required carburized layer.
[0004] When the transmission equipment transfers the shaft hinge upward, the carburizing box will start to carburize the shaft hinge. Since the lower area of the carburizing box is not sealed, the heat inside the carburizing box will dissipate, which will cause the heat inside the carburizing box to decrease, and then cause the surface hardness of the parts to be insufficient, and fail to meet the expected hardness requirements, thereby affecting its wear resistance and fatigue resistance. In addition, when the shaft hinge is being transmitted, the distance between the upper and lower shaft hinges cannot be adjusted, resulting in the upper and lower shaft hinges being too close. Too close a distance will hinder the full circulation of the atmosphere in the furnace, resulting in an uneven carburizing layer and local insufficient or excessive carburizing.
[0005] Therefore, it is necessary to design a heat-treated shaft hinge parts transmission device that automatically adjusts the parts distance and carburizes evenly to improve the above-mentioned technical problems. Summary of the invention
[0006] In view of the deficiencies in the prior art, the present invention aims to provide a heat-treated shaft hinge parts transmission device.
[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a heat-treated shaft hinge parts transmission device, comprising a slide rail, a carburizing box is fixedly connected to the upper side of the slide rail, a conveying mechanism for transporting the shaft hinge is provided on one side of the carburizing box, an adjusting mechanism for adjusting the distance between the upper and lower shaft hinges and indirectly cleaning the accumulated carbon black is provided on the upper side of the conveying mechanism, and a drainage mechanism for introducing heat into the center of the adjusting mechanism is provided inside the adjusting mechanism.
[0008] The present invention is further configured as follows: the conveying mechanism includes four electric rollers slidably connected to the inside of the slide rail, the upper side of the electric roller is fixedly connected to a support frame, the inside of the support frame is evenly fixedly connected to four electric push rods, the output ends of the four electric push rods all pass through the support frame, the inside of the support frame is slidably connected to a fixed plate, the lower inner wall of the fixed plate is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a U-shaped plate, and the inside of the U-shaped plate is fixedly connected to a motor.
[0009] The present invention is further configured as follows: the adjusting mechanism includes a closing plate fixedly connected to the output ends of four electric push rods, the closing plate is a manganese metal plate with poor thermal conductivity, the fixing plate is fixedly connected to the closing plate, and the upper side of the closing plate is sequentially provided with a first support plate, a second support plate, a third support plate and a fourth support plate, two third connecting rods are respectively hinged on both sides of the first support plate, the two third connecting rods are hinged to each other, the other ends of the two third connecting rods are respectively hinged to the second connecting rods, the two second connecting rods are hinged to each other, the other ends of the two second connecting rods are respectively hinged to the first connecting rods, and the two first connecting rods are hinged to each other.
[0010] The present invention is further configured as follows: both sides of the second support plate are hinged to the second connecting rod and the third connecting rod, both sides of the third support plate are hinged to the first connecting rod and the second connecting rod, and both sides of the fourth support plate are hinged to the first connecting rod.
[0011] The present invention is further configured as follows: the first support plate, the second support plate, the third support plate and the fourth support plate have the same structure, the fourth support plate is composed of two guide slides and a slide, the slide is slidably connected between the two guide slides, and the first support plate is fixedly connected to the closing plate.
[0012] By precisely controlling the extension of the output end of the electric push rod, the four walls of the closed plate are tightly fitted with the inner wall of the carburizing box. This design effectively prevents the loss of most of the heat inside the carburizing box, ensures the stability of the temperature inside the box, and thus provides a good thermal environment for the carburizing process. At the same time, the output end of the cylinder extends, driving the first connecting rod, the second connecting rod and the third connecting rod to unfold. This action increases the distance between the upper and lower shaft hinges. As the distance between the shaft hinges increases, the atmosphere inside the carburizing box can be more fully circulated and distributed, allowing carbon particles to more evenly contact various parts of the parts, thereby significantly improving the uniformity of the carburized layer. This optimized mechanical structure and control method not only improves the carburizing efficiency, but also ensures the quality and performance of the carburized layer on the surface of the parts, laying a solid foundation for the subsequent heat treatment process.
[0013] The present invention is further configured as follows: the first connecting rod, the second connecting rod and the third connecting rod are each provided with a second avoidance groove inside, the first connecting rod is respectively hinged with a first scraper, a second scraper and a third scraper inside, and the second scraper is provided with a first avoidance groove inside.
[0014] The present invention is further configured as follows: a fourth scraper, a fifth scraper and a sixth scraper are respectively hinged inside the second connecting rod, a third avoidance groove is provided inside the fifth scraper, three first collecting boxes are evenly fixedly connected inside the second avoidance groove of the second connecting rod, and three second collecting boxes are evenly fixedly connected inside the second avoidance groove of the third connecting rod.
[0015] By controlling the output end of the cylinder to retract, the first connecting rod, the second connecting rod and the third connecting rod can be driven to retract. This process not only reduces the height of the top shaft hinge, but also effectively prevents the top shaft hinge from hitting the carburizing box when it is subsequently moved to the outside of the carburizing box, thereby ensuring the safety and smooth operation of the equipment. At the same time, the retraction action of the cylinder also indirectly controls the rotation of the first scraper, the second scraper, the third scraper, the fourth scraper, the fifth scraper and the sixth scraper. During the rotation process, these scrapers can clean up most of the carbon black above the second and third connecting rods, avoiding the problem of the connecting rods being unable to fully retract due to the accumulation of carbon black. In this way, the phenomenon of the shaft hinge being stuck inside the carburizing box is effectively prevented, thereby improving the efficiency and reliability of the entire conveying system and ensuring the continuity and stability of the production process.
[0016] The present invention is further configured as follows: the drainage mechanism includes an air guide tube fixedly connected to the output end of the motor, the inner wall of the air guide tube is evenly provided with a plurality of air outlet holes, a heat-conducting fan is fixedly connected to the upper inner part of the air guide tube, three supporting trays are evenly fixedly connected to the outer wall of the air guide tube, and a supporting ring is also fixedly connected to the outer wall of the air guide tube.
[0017] The present invention is further configured as follows: a plurality of positioning grooves are evenly fixedly connected to the upper inner wall of the supporting tray, a plurality of second ventilation holes are evenly arranged inside the supporting tray, the upper side of each of the second ventilation holes is connected to a plurality of first ventilation holes, a positioning rod is arranged on the upper side of each of the positioning grooves, and the positioning rod is hinged to the supporting tray.
[0018] By controlling the rotation of the shaft hinge and the heat conduction fan through the motor, a large amount of carbon particles in other areas can be effectively sucked into the air guide tube, that is, the middle area of the support tray. These carbon particles are then discharged through the air outlet tunnel, the second ventilation hole and the internal channel of the first ventilation hole. The discharged carbon particles are evenly distributed on the support tray, and the surface of the shaft hinge is evenly carburized. This process not only ensures the uniformity of the carburized layer, but also effectively prevents the shaft hinge in the middle of the support tray from being partially under-carburized or over-carburized.
[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. By controlling the output end of the electric push rod to extend, the four walls of the closing plate fit with the inner wall of the carburizing box, which effectively prevents the loss of most of the heat inside the carburizing box. The output end of the cylinder extends to drive the first connecting rod, the second connecting rod and the third connecting rod to expand, thereby increasing the distance between the upper and lower rotating shaft hinges, allowing the atmosphere inside the carburizing box to circulate fully, thereby improving the uniformity of the carburizing layer.
[0020] 2. By retracting the output end of the cylinder, the first connecting rod, the second connecting rod and the third connecting rod are driven to retract, which not only reduces the height of the uppermost rotating shaft hinge to prevent the uppermost rotating shaft hinge from hitting the carburizing box when moving to the outside of the carburizing box later, but also indirectly controls the rotation of the first scraper, the second scraper, the third scraper, the fourth scraper, the fifth scraper and the sixth scraper, and cleans most of the carbon black above the second connecting rod and the third connecting rod, effectively preventing the second connecting rod and the third connecting rod from being unable to fully retract and the rotating shaft hinge from being stuck inside the carburizing box, thereby achieving a high conveying efficiency.
[0021] 3. The motor controls the rotation of the shaft hinge and the heat-conducting fan, thereby absorbing a large amount of carbon particles from other areas into the air guide tube, that is, the middle area of the support tray, and then discharging them through the air outlet tunnel, the second ventilation hole and the first ventilation hole in turn. The discharged carbon particles evenly carburize the surface of the shaft hinge on the support tray, achieving a uniform carburizing effect, and effectively preventing the uneven carburizing layer of the shaft hinge in the middle of the support tray, resulting in local insufficient or excessive carburizing.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0026] For example, see Figure 1-10 The present invention provides the following technical solutions: a heat-treated rotating shaft hinge parts transmission device, comprising a slide rail 1, a carburizing box 2 is fixedly connected to the upper side of the slide rail 1, a conveying mechanism 3 for transporting the rotating shaft hinge is provided on one side of the carburizing box 2, an adjusting mechanism 4 for adjusting the distance between the upper and lower rotating shaft hinges and indirectly cleaning the accumulated carbon black is provided on the upper side of the conveying mechanism 3, and a drainage mechanism 5 for introducing heat into the center of the adjusting mechanism 4 is provided inside the adjusting mechanism 4.
[0027] Specifically, the interior of the carburizing box 2 is used to carburize the rotating shaft hinge, and the slide rail 1 is used to guide the conveying mechanism 3.
[0028] See also Figure 2 The conveying mechanism 3 includes four electric rollers 31 slidably connected to the inside of the slide rail 1, a support frame 32 is fixedly connected to the upper side of the electric roller 31, four electric push rods 33 are evenly fixedly connected to the inside of the support frame 32, the output ends of the four electric push rods 33 all pass through the support frame 32, a fixed plate 37 is slidably connected to the inside of the support frame 32, a cylinder 36 is fixedly connected to the lower inner wall of the fixed plate 37, a U-shaped plate 35 is fixedly connected to the output end of the cylinder 36, and a motor 34 is fixedly connected to the inside of the U-shaped plate 35.
[0029] Specifically, the electric roller 31 is controlled to rotate by an internal driving motor, thereby driving the adjustment mechanism 4 and the drainage mechanism 5 to move, and then driving the shaft hinge to move to the inside of the carburizing box 2. The extension of the output end of the electric push rod 33 is used to control the upward movement of the adjustment mechanism 4 and the drainage mechanism 5, so that the shaft hinge moves to the carburizing area of the carburizing box 2. When the electric push rod 33 is fully extended, the four walls of the closing plate 41 fit against the inner wall of the carburizing box 2 to form a closed box to prevent most of the heat from being lost. The rotation of the output end of the motor 34 is used to control the rotation of the drainage mechanism 5, and the extension of the output end of the cylinder 36 is used to control the expansion of the adjustment mechanism 4, thereby increasing the distance between the two shaft hinges.
[0030] See also Figure 3 The adjusting mechanism 4 includes a closing plate 41 fixedly connected to the output ends of the four electric push rods 33, the closing plate 41 is a manganese metal plate with poor thermal conductivity, the fixing plate 37 is fixedly connected to the closing plate 41, and the upper side of the closing plate 41 is provided with a first support plate 42, a second support plate 43, a third support plate 44 and a fourth support plate 45 in sequence, and two third connecting rods 48 are hinged on both sides of the first support plate 42, respectively. The two third connecting rods 48 are hinged to each other, and the other ends of the two third connecting rods 48 are hinged to the second connecting rods 47, respectively, and the two second connecting rods 47 are hinged to each other. The other ends of the two second connecting rods 47 are respectively hinged to the first connecting rods 46, and the two first connecting rods 46 are hinged to each other.
[0031] Specifically, when the shaft hinge needs to be carburized, the electric roller 31 drives the shaft hinge to move to the inside of the carburizing box 2. At this time, the output end of the electric push rod 33 extends out to control the shaft hinge to move upward, thereby moving the shaft hinge to the carburizing area of the carburizing box 2. When the electric push rod 33 is fully extended, the four walls of the closing plate 41 fit against the inner wall of the carburizing box 2 to prevent heat loss in the carburizing area. The output end of the cylinder 36 extends out to drive the motor 34 to move upward, thereby driving the drainage mechanism 5 to move upward, and then the fourth support plate 45 is driven by the drainage mechanism 5 to move upward. While the fourth support plate 45 moves, the first support plate 42 and the second support plate 43 move at the same time, thereby driving the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 to expand. At this time, the distance between the upper and lower shaft hinges increases, so that the atmosphere inside the carburizing box 2 is fully circulated, thereby improving the uniformity of the carburized layer.
[0032] When the carburizing of the shaft hinge is completed, the output end of the cylinder 36 retracts, and the fourth support plate 45 is driven by the drainage mechanism 5 to move downward. While the fourth support plate 45 moves, the first support plate 42 and the second support plate 43 move at the same time, thereby driving the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 to contract. At this time, the distance between the upper and lower shaft hinges is shortened, and the height of the uppermost shaft hinge is reduced, which effectively prevents the uppermost shaft hinge from colliding with the carburizing box 2 when it moves to the outside of the carburizing box 2 subsequently. The output end of the electric push rod 33 retracts, controlling the shaft hinge to move up and down, thereby causing the shaft hinge to leave the carburizing area of the carburizing box 2. Finally, the electric roller 31 drives the shaft hinge to move out of the inside of the carburizing box 2.
[0033] Both sides of the second support plate 43 are hinged to the second connecting rod 47 and the third connecting rod 48 , both sides of the third support plate 44 are hinged to the first connecting rod 46 and the second connecting rod 47 , and both sides of the fourth support plate 45 are hinged to the first connecting rod 46 .
[0034] See also Figure 4 The first support plate 42, the second support plate 43, the third support plate 44 and the fourth support plate 45 have the same structure. The fourth support plate 45 is composed of two guide slides 452 and a slide plate 451. The slide plate 451 is slidably connected between the two guide slides 452. The first support plate 42 is fixedly connected to the closing plate 41.
[0035] Specifically, when the first link 46, the second link 47 and the third link 48 are unfolded, the two guide slides 452 slide toward the slide 451. On the contrary, when the first link 46, the second link 47 and the third link 48 are retracted, the two guide slides 452 slide in the opposite direction.
[0036] By controlling the output end of the electric push rod 33 to extend, the four walls of the closing plate 41 are fitted with the inner wall of the carburizing box 2, which effectively prevents most of the heat loss inside the carburizing box 2. The output end of the cylinder 36 extends, driving the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 to expand, thereby increasing the distance between the upper and lower rotating shaft hinges, allowing the atmosphere inside the carburizing box 2 to circulate fully, thereby improving the uniformity of the carburizing layer.
[0037] In the second embodiment, after the carburizing of the rotating shaft hinge is completed, carbon black will accumulate above the three connecting rods. The accumulation of carbon black will prevent the two connecting rods from completely contracting, causing the two connecting rods to get stuck when they are contracted, thereby causing the height of the top rotating shaft hinge to be unable to drop to a safe area. When moving out of the carburizing box 2, it will collide with the carburizing box 2, causing the rotating shaft hinge to get stuck inside the carburizing box 2, making it impossible to transport the subsequent rotating shaft hinge, thereby reducing the transportation efficiency of the rotating shaft hinge.
[0038] See also Figure 5-Figure 7 The first link 46, the second link 47 and the third link 48 are each provided with a second avoidance groove 465, the first link 46 is respectively hinged with a first scraper 461, a second scraper 462 and a third scraper 464, and the second scraper 462 is provided with a first avoidance groove 463.
[0039] Specifically, when the first link 46, the second link 47 and the third link 48 are fully extended to their maximum positions, due to gravity, the first scraper 461, the second scraper 462 and the third scraper 464 will rotate from the second avoidance groove 465 on the first link 46, thereby naturally drooping to form a vertical downward state. Similarly, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 will also rotate from the second avoidance groove 465 on the second link 47, presenting a vertical downward state. Since the scraper is in a vertical downward position, this helps to prevent carbon black from accumulating on the scraper because gravity will make the carbon black easier to slide off, thereby keeping the scraper clean and operating effectively.
[0040] The fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 are hinged inside the second connecting rod 47, the third avoidance groove 474 is provided inside the fifth scraper 473, the second avoidance groove 465 of the second connecting rod 47 has three first collecting boxes 471 evenly fixedly connected inside, and the second avoidance groove 465 of the third connecting rod 48 has three second collecting boxes 481 evenly fixedly connected inside.
[0041] Specifically, the first collecting box 471 and the second collecting box 481 are used to collect the carbon black generated above the second connecting rod 47 and the third connecting rod 48, respectively. When the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 begin to change from the fully extended state to the retracted state, the first scraper 461, the second scraper 462 and the third scraper 464 will move downward with the contraction of the connecting rods until they abut against the upper surface of the second connecting rod 47, see Figure 8 Subsequently, the first scraper 461, the second scraper 462 and the third scraper 464 will move along the length direction of the second connecting rod 47. Through the movement of the scrapers, the carbon black attached to the top of the second connecting rod 47 will be effectively scraped off. As the scrapers advance, the scraped carbon black will be guided and pushed into each first collecting box 471 in turn, thereby realizing the orderly collection and treatment of the carbon black above the second connecting rod 47.
[0042] As the first link 46, the second link 47 and the third link 48 retract, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 move downward until they contact the upper surface of the third link 48, and then the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 move along the length direction of the third link 48 to effectively scrape off the carbon black attached to the top of the third link 48. As the scrapers advance, the scraped carbon black will be guided and pushed into each second collection box 481 in turn, thereby achieving the third link 48, when the first link 46, the second link 47 and the third link 48 are fully retracted to their initial positions, most of the carbon black above the second link 47 and the third link 48 has been cleaned up. At this time, the first scraper 461, the second scraper 462 and the third scraper 464 will return to the second avoidance groove 465 on the first link 46, and the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 will return to the second avoidance groove 465 on the second link 47, preparing for the next scraping action.
[0043] By retracting the output end of the cylinder 36, the first connecting rod 46, the second connecting rod 47 and the third connecting rod 48 are driven to retract, which not only reduces the height of the uppermost rotating shaft hinge to prevent the uppermost rotating shaft hinge from hitting the carburizing box 2 when moving to the outside of the carburizing box 2 later, but also indirectly controls the first scraper 461, the second scraper 462, the third scraper 464, the fourth scraper 472, the fifth scraper 473 and the sixth scraper 475 to rotate, so that most of the carbon black above the second connecting rod 47 and the third connecting rod 48 is cleaned, and the second connecting rod 47 and the third connecting rod 48 are effectively prevented from being unable to fully retract and the rotating shaft hinge being stuck inside the carburizing box 2, thereby achieving a high conveying efficiency.
[0044] Embodiment 3, in the carburizing box 2, since the carburizing mechanism inside is mainly distributed on the four inner walls, it is difficult for the carbon particles to reach the middle area of the support tray 55 evenly. On the contrary, a large amount of carbon particles will be sprayed on the outside of the support tray 55. Due to this uneven distribution, the rotating shaft hinges in the middle and outside of the support tray 55 cannot effectively obtain a uniform carburizing effect. As a result, the rotating shaft hinge in the middle of the support tray 55 has an uneven carburizing layer, which may cause insufficient carburization in a local area, while other areas may be over-carburized.
[0045] See also Fig. 9 and Fig.10 The drainage mechanism 5 includes an air guide tube 52 fixedly connected to the output end of the motor 34, a plurality of air outlet holes 51 are evenly arranged on the inner wall of the air guide tube 52, a heat conduction fan 53 is fixedly connected to the upper part of the interior of the air guide tube 52, three supporting trays 55 are evenly fixedly connected to the outer wall of the air guide tube 52, and a supporting ring 54 is also fixedly connected to the outer wall of the air guide tube 52.
[0046] Specifically, the support ring 54 is used to support the fourth support plate 45 to move upward, and the support tray 55 is used to place a large number of rotating shaft hinges that need to be carburized. The rotation of the output end of the motor 34 is used to control the three support trays 55 and the air guide tube 52 to rotate quickly, thereby controlling the rotating shaft hinge and the heat-conducting fan 53 to rotate quickly. When the rotating shaft hinge rotates, the diffusion of carbon atoms to the surface of the rotating shaft hinge can be accelerated, so that the carbon element can penetrate into the surface of the rotating shaft hinge more evenly, thereby improving the carburizing efficiency. In addition, during the rotation process, the contact between the rotating shaft hinge surface and the carburizing medium is more sufficient. The fast rotation can also prevent the hinge from staying in a certain position for a long time, reduce the occurrence of local over-permeation, and ensure the uniformity of the carburized layer. When the heat-conducting fan 53 rotates, suction can be generated above the air guide tube 52 to suck a large amount of carbon particles above the air guide tube 52 into the air guide tube 52. The large amount of particles inside the air guide tube 52 are then discharged from each air outlet hole 51 inside the air guide tube 52, thereby transferring a large amount of carbon particles in other areas to the middle area of the support tray 55.
[0047] A plurality of positioning grooves 553 are evenly fixedly connected to the upper inner wall of the supporting tray 55, a plurality of second ventilation holes 552 are evenly arranged inside the supporting tray 55, and a plurality of first ventilation holes 551 are connected to the upper side of each second ventilation hole 552, a positioning rod 554 is arranged on the upper side of each positioning groove 553, and the positioning rod 554 is hinged to the supporting tray 55.
[0048] Specifically, the positioning groove 553 is used to place the rotating shaft hinge, and the positioning rod 554 is used to fix each rotating shaft hinge to prevent the rotating shaft hinge from being thrown away when it rotates rapidly. When a large amount of carbon particles are discharged from each air outlet hole 51 inside the air guide tube 52, some of the carbon particles will be directly arranged in the upper area of each rotating shaft hinge, and other carbon particles will enter the second ventilation hole 552 again. The second ventilation hole 552 is located on the lower side or left and right sides of each rotating shaft hinge, and then transmitted from the inside of the second ventilation hole 552 to the inside of each first ventilation hole 551. The first ventilation hole 551 then transmits some of the carbon particles to the surrounding area of each rotating shaft hinge, that is, the bottom, left and right sides of each rotating shaft hinge, so as to uniformly carburize each rotating shaft hinge.
[0049] The motor 34 controls the rotation of the shaft hinge and the heat-conducting fan 53, so that a large amount of carbon particles in other areas are sucked into the interior of the air guide tube 52, that is, the middle area of the support tray 55, and then discharged through the air outlet tunnel 51, the second ventilation hole 552 and the first ventilation hole 551 in sequence. The discharged carbon particles uniformly carburize the surface of the shaft hinge on the support tray 55, achieving a uniform carburization effect, and effectively preventing the uneven carburization layer of the shaft hinge in the middle of the support tray 55, and the occurrence of local insufficient or excessive carburization.
[0050] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
