[0041] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0042] Figure 1 The diagram illustrates the structure of a heating module in a rapid heat treatment apparatus, including a mounting frame 700 and multiple heating tubes 800 mounted on the mounting frame 700. Each heating tube 800 houses a heating lamp and serves to seal and protect the heating lamp. The ends of the heating tubes 800 are secured and sealed using pressure rings 900. In related technologies, the pressure rings 900 are manually installed onto the mounting frame 700 to secure the ends of the heating tubes 800, which is both laborious and time-consuming, severely impacting the assembly speed of the heating module.

[0043] To address the above issues, this embodiment provides a fixing fixture for rotating the pressure ring 900, which in turn fixes the heating element 800. Of course, the fixing fixture provided in this embodiment is not limited to fixing the heating element 800, but can also be used in similar assembly processes.

[0044] Specifically, such as Figure 3 As shown, and refer to Figure 2 As shown, the fixing fixture provided in this embodiment includes a rotating rod 100, a rotating core 400, and a lever 300. The rotating core 400 is disposed on the rotating rod 100 and is configured to be able to be inserted into the central hole 910 of the pressure ring 900 and to be able to rotate under the drive of the rotating rod 100. The lever 300 is disposed on the rotating rod 100 and is configured to be able to be relatively close to or far away from the rotating core 400 so as to be inserted into or disengaged from the pin hole 920 on the outer peripheral wall of the pressure ring 900.

[0045] The fixing fixture provided in this embodiment is used to fix the heating tube 800 to the mounting frame 700. In use, the lever 300 and the rotating core 400 can be moved away from each other first, so that the rotating core 400 can be easily inserted into the center hole 910 of the pressure ring 900. After aligning the lever 300 with the pin hole 920 on the outer peripheral wall of the pressure ring 900, the lever 300 and the rotating core 400 can be moved closer to each other so that the lever 300 can be inserted into the pin hole 920. After the rotating core 400 and the lever 300 are installed in place, the rotating rod 100 can be rotated, and the pressure ring 900 can be rotated inward by the lever 300, thereby fixing the end of the heating tube 800 to the mounting frame 700. Compared to directly rotating the pressure ring 900 by hand to fix the heating tube 800, using the fixing fixture provided in this embodiment is labor-saving, time-saving, and very convenient, which can greatly improve the assembly speed of the heating tube 800. Moreover, compared to direct manual operation, using the fixing fixture provided in this embodiment, the rotating core 400 can also play a positioning and support role for both the rotating rod 100 and the lever 300 during rotation. Therefore, the direction of the force applied by the lever 300 to the pressure ring 900 is more accurate, which can effectively avoid stress concentration and thus prevent the heating tube 800 from being crushed. The assembly accuracy of the pressure ring 900 and the heating tube 800 is also higher.

[0046] More specifically, in this embodiment, as Figure 6 As shown, a sealing ring 930 and a pressure bushing 940 can also be provided on the outer side of the end of the heating tube 800. The sealing ring 930 is located on the side of the pressure bushing 940 away from the pressure ring 900. The pressure ring 900 pushes the pressure bushing 940 to install the pressure bushing 940 and the sealing ring 930 into place, so that the three together fix and seal the end of the heating tube 800.

[0047] Specifically, in this embodiment, as Figures 2 to 9 As shown, the axis of the rotating rod 100 is perpendicular to the axis of the rotating core 400. With this arrangement, the lever arm is relatively long when rotating the rotating rod 100, so it requires less effort; moreover, the space affected by the rotating rod 100 is also relatively small, which can effectively avoid interference.

[0048] Specifically, in this embodiment, the rotating core 400 is provided with a slot, and the rotating rod 100 is movably inserted into the slot. With this configuration, by moving the rotating rod 100 along the slot, the lever 300 can be moved closer to or away from the rotating core 400. Figure 7 The direction indicated by the middle arrow ab is the direction of movement of the rotating rod 100 and the lever 300 relative to the rotating core 400. When the lever 300 and the rotating core 400 are far apart, the rotating core 400 can be easily inserted into the center hole 910 of the pressure ring 900; after the rotating core 400 is inserted into place, the rotating rod 100 is moved in the direction that the lever 300 is close to the rotating core 400, so that the lever 300 can be inserted into the pin hole 920 of the pressure ring 900.

[0049] Specifically, in this embodiment, the center line of the slot intersects perpendicularly with the axis of the rotating core 400. With this configuration, the torque applied to the rotating core 400 by the rotating rod 100 and the torque applied to the pressure ring 900 by the lever 300 are both centered on the common axis of the rotating core 400 and the pressure ring 900. Therefore, the pressure ring 900 is less prone to skewing and jamming, effectively ensuring assembly speed.

[0050] Specifically, in this embodiment, as Figure 4 As shown, the rotating rod 100 includes a body 110 and a connector 120 located at one end of the body 110; a limiting step 111 is formed at the connection between the body 110 and the connector 120, which is used to prevent the body 110 from being inserted into the slot. With this configuration, the relative travel of the rotating rod 100 and the rotating core 400 is relatively limited, which can ensure the normal use of the fixed fixture and avoid unnecessary relative movement, thus ensuring the assembly speed.

[0051] Specifically, in this embodiment, the following continues... Figure 4 As shown, a first limiting member 121 is provided at the end of the insertion part 120 away from the body 110. The first limiting member 121 is used to prevent the rotating rod 100 from disengaging from the slot along its axial direction. With this configuration, the first limiting member 121 can effectively prevent the rotating rod 100 from disengaging from the slot. The relative movement of the rotating rod 100 and the lever 300 with the rotating core 400 is the distance between the limiting step 111 and the limiting surface of the first limiting member 121.

[0052] Specifically, in this embodiment, as Figure 4 and Figure 6 As shown, there are two first limiting members 121, which are arranged along the axial direction of the rotating core 400. This arrangement makes the limiting effect of the two first limiting members 121 on the rotating rod 100 more reliable.

[0053] Specifically, in this embodiment, the first limiting member 121 is a first flat-head screw, the head of which is used to prevent the rotating rod 100 from disengaging from the slot. Flat-head screws are readily available and inexpensive. Of course, in other embodiments of this application, the first limiting member 121 is not limited to a flat-head screw; for example, the first limiting member 121 can also be a limiting block or limiting plate fixed to the end face of the rotating rod 100.

[0054] It should also be noted that in other embodiments of this application, the limiting step 111 and the first limiting member 121 may be provided only one of them, or neither may be provided. However, the operator needs to carefully control the rotating rod 100 during use to prevent it from detaching from the rotating core 400.

[0055] Specifically, in this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, along the rotation direction of the rotating rod 100 ( Figure 8 (As indicated by the middle arrow cd), both sides of the body 110 near the insertion part 120 are provided with inclined planes 112 to avoid components on the corresponding side of the inclined plane 112. This arrangement effectively prevents interference between the rotating rod 100 and other components when rotating the rod 100; moreover, the rotating rod 100 uses less material, saving costs. Of course, in other embodiments of this application, the body 110 may only have one side with an inclined plane 112.

[0056] Specifically, in this embodiment, the lever 300 is detachably mounted on the rotating rod 100. This configuration allows for easy replacement of levers 300 of different lengths or diameters, thus enabling the fixture to be adapted to pressure rings 900 with different diameters or different hole diameters in the pin holes 920.

[0057] Specifically, in this embodiment, as Figure 2 and Figure 3 As shown, the fixture also includes a mounting base 200, which is detachably and fixedly mounted on the rotating rod 100. The lever 300 is fixedly mounted on the mounting base 200. This configuration allows for easy replacement of the entire mounting base 200 and lever 300. Besides replacing the entire lever 300 with different lengths or diameters, it also allows for replacement of the entire fixture including different mounting bases 200. If different mounting bases 200 allow for different distances between the lever 300 and the rotating rod 100, then by replacing the entire fixture, it can be adapted to pressure rings 900 of different thicknesses, thus further expanding the applicability of the fixture.

[0058] Specifically, in this embodiment, the end of the mounting base 200 away from the rotating rod 100 is provided with a countersunk hole, and the lever 300 is T-shaped and inserted into the countersunk hole; the mounting base 200 is provided with a second limiting member 221, which is used to prevent the lever 300 from moving away from the countersunk hole. With this configuration, the mating structure of the lever 300 and the countersunk hole, as well as the second limiting member 221, together limit the lever 300, fixing it to the mounting base 200.

[0059] Specifically, in this embodiment, the second limiting member 221 is a second flat-head screw, the head of which is used to block the lever 300. Flat-head screws are readily available and inexpensive. Of course, in other embodiments of this application, the second limiting member 221 is not limited to a flat-head screw; for example, the second limiting member 221 can also be a limiting block or limiting plate fixed to the mounting base 200.

[0060] Specifically, in this embodiment, as Figure 3 As shown, and in combination Figure 6As shown, the rotating rod 100 is provided with a receiving groove 113, and the end of the mounting base 200 away from the lever 300 is fixedly disposed in the receiving groove 113. The receiving groove 113 provides accommodating space for the end of the mounting base 200. Compared with the mounting base 200 being disposed on the outer peripheral wall of the rotating rod 100, the end of the mounting base 200 is disposed in the receiving groove 113, which is more convenient to set up and can effectively avoid interference between the mounting base 200 and the pressure ring 900, etc., and the overall structure of the fixing fixture is also more compact.

[0061] Specifically, in this embodiment, as Figure 3 As shown, and refer to Figure 6 As shown, the mounting base 200 is T-shaped and includes a first fixing block 210 and a second fixing block 220 vertically disposed on the first fixing block 210. The first fixing block 210 is disposed within the receiving groove 113; the second fixing block 220 extends out of the receiving groove 113, and the lever 300 is mounted on the end of the second fixing block 220 away from the first fixing block 210. This configuration provides a relatively large connection area between the mounting base 200 and the rotating rod 100, which helps to improve the connection strength between the two.

[0062] More specifically, in this embodiment, as Figure 6 As shown, the mounting base 200 is fixed in the receiving groove 113 by countersunk screws 211. With this configuration, the countersunk screws 211 are recessed into the mounting base 200, which can effectively prevent them from interfering with the pressure ring 900 or other components.

[0063] Specifically, in this embodiment, as Figure 3 As shown, and in combination Figure 4 and Figure 6 As shown, the rotating core 400 includes a connecting portion 410 and an insertion portion 420 fixedly connected along its axial direction. The connecting portion 410 is connected to the rotating rod 100. The insertion portion 420 is fitted with a positioning ring 500, which includes a radial positioning portion 510 extending along its own axial direction and an axial positioning portion 520 extending along its own radial direction. The outer diameter of the radial positioning portion 510 matches the inner diameter of the pressure ring 900, and the axial positioning portion 520 can abut against the outer end face of the pressure ring 900. With this configuration, the radial positioning portion 510 of the positioning ring 500 provides radial positioning for the rotating core 400 by abutting against the inner circumferential surface of the pressure ring 900, and the axial positioning portion 520 of the positioning ring 500 provides axial positioning for the rotating core 400 by abutting against the outer end face of the pressure ring 900. Therefore, when the rotating rod 100 is rotated, the lever 300 can stably rotate the pressure ring 900. In addition, the positioning ring 500 isolates the rotating core 400 from the pressure ring 900, thereby protecting the pressure ring 900.

[0064] Specifically, in this embodiment, as Figure 3 and Figure 4As shown, the insertion portion 420 of the rotating core 400 is also fitted with a retaining ring 600. The retaining ring 600 is located on the side of the positioning ring 500 away from the rotating rod 100, and is used to prevent the positioning ring 500 from disengaging from the rotating core 400 in a direction away from the rotating rod 100. With this configuration, the retaining ring 600 can effectively prevent the positioning ring 500 from disengaging from the rotating core 400, especially when the rotating core 400 is pulled out from the pressure ring 900.

[0065] Specifically, in this embodiment, the positioning ring 500 is mainly made of a flexible material. For example, the positioning ring 500 can be made of resin. This design ensures that the hardness of the positioning ring 500 is less than that of the pressure ring 900, effectively preventing scratches on the pressure ring 900.

[0066] Specifically, in this embodiment, the rotating rod 100 is provided with an external connection part, which is used to connect with the force-applying rod. By connecting the external force-applying rod, the lever arm can be lengthened, thereby making the assembly work more labor-saving.

[0067] Specifically, in this embodiment, as Figure 2 and Figure 6 As shown, the end of the lever 100 away from the rotating core 400 is provided with a socket 130, which forms an external connection. With this design, when it is necessary to extend the lever arm, the extension rod can be inserted into the socket 130, which is convenient and quick.

[0068] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0069] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
