Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of main heater of single crystal furnace, and particularly relates to a fixing clamp for main heater foot plate and a main heater. BACKGROUND

[0002] The length of the foot plate of the graphite main heater used in the single crystal furnace shows a trend of gradual increase. Since the foot plate itself is relatively heavy, it will swing significantly during transportation. The traditional manual loading and unloading method cannot prevent the swing, thereby increasing the potential risk of hidden cracks and bringing many uncontrollable safety hazards to the crystal pulling process in the furnace.

[0003] At present, the fixing method of the heater foot plate is mainly completed through wood and a strap. Specifically, the strap is passed through the holes on the foot plates and the two foot plates are fixed together. However, the operation steps of this method are quite cumbersome, not only the strap needs to be passed into the hole of the foot plate and tightened, but also the excess strap part needs to be cut off. In addition, the whole strap needs to be cut off every time it is taken off, which causes waste of materials. At the same time, the standardization of this fixing method is poor, because although it is fixed through the foot plate hole, the length of the wood plate will change due to the deformation caused by moisture or aging of the wood, thereby causing the foot plate to be pulled and deformed.

[0033] As Figures 1 to 5 indicated, a first aspect of the present application provides a fixing clamp for main heater foot plate, which comprises a clamp body 1 and a clamping block 2.

[0034] In the following description, reference is made to the Figures 1 to 5 The specific structure of the above components of the fixing clamp for main heater foot plate and the connection relationship of the above components are specifically described.

[0035] As Figures 1 to 5 indicated, in the embodiment, the first side (which can be the lower side as Figure 3 indicated) of the clamp body 1 can be formed with a receiving groove 10 for accommodating the foot plate of the main heater. The foot plate of the main heater can be clamped in the receiving groove 10, so that the fixing clamp for main heater foot plate is wrapped outside the foot plate to avoid shaking or bumping of the foot plate during transportation and reduce non-production damage caused during transportation. The clamping block 2 can be arranged in the receiving groove 10 of the clamp body 1. In the case where the foot plate is clamped in the receiving groove 10, the clamping block 2 can be clamped in the foot plate hole of the foot plate to further position and protect the foot plate.

[0036] Preferably, as Figures 1 to 4 indicated, in the embodiment, the clamp body 1 can further comprise a clamping rod 3. Specifically, the clamping rod 3 can be a cylindrical rod. The clamping rod 3 can be fixedly installed on the clamp body 1, and the two clamping blocks 2 can be respectively installed on the two ends of the clamping rod 3. In this way, the clamping blocks 2 can be fixed to the clamp body 1, and the foot plate of the main heater can be fixed to the clamp body 1.

[0037] Further, preferably, in the embodiment, the distance between the two ends of the clamping rod 3 can be consistent with the distance between the foot hole of the two foot plates of the main heater. In this way, the positions of the two clamping blocks 2 mounted on the two ends of the clamping rod 3 can correspond to the positions of the foot holes of the two foot plates of the main heater, so that the two clamping blocks 2 can be clamped into the foot holes of the two foot plates at the same time, thereby synchronously positioning the two foot plates of the main heater.

[0038] Preferably, as shown in Figure 2 , Figure 4 and Figure 5 , in the embodiment, threaded holes 31 can be formed at the end faces of the two ends of the clamping rod 3. A threaded stud 20 can be arranged at the end of the clamping block 2. The external thread of the threaded stud 20 can cooperate with the internal thread of the threaded hole 31, so that the clamping block 2 can be threadedly connected with the end of the clamping rod 3, thereby fixing the clamping block 2 to the clamping rod 3.

[0039] However, not limited to this, in the embodiment, threaded holes 31 are formed at the end faces of the two ends of the clamping rod 3, and threaded studs 20 are arranged at the ends of the clamping blocks 2, which is only one of the preferred fixing methods in the embodiment. In actual use, as long as the clamping rod 3 and the clamping block 2 can be fixedly connected, other fixing methods can also be used between the clamping rod 3 and the clamping block 2, for example, threaded studs are arranged at the end faces of the two ends of the clamping rod, and threaded holes are formed at the ends of the clamping blocks, which can cooperate with the threaded studs. Or, clasp structures are arranged at the two ends of the clamping rod and the ends of the clamping block, so that the clamping rod and the clamping block can be clamped. In this way, the purpose of fixing the clamping blocks to the two ends of the clamping rod can also be achieved.

[0040] Preferably, as shown in Figures 1 to 4 , in the embodiment, the two ends of the clamping rod 3 can be formed with bending portions 30 (i.e., the ends of the clamping rod 3 are bent). Specifically, the bending angle of the bending portion 30 can be 90°, so that the axial direction of the clamping block 2 is perpendicular to the axial direction of the clamping rod 3, to facilitate the simultaneous installation of the clamping block 2 and the clamping rod 3 to the clamp body 1. At the same time, the two bending portions 30 can be bent to the same side of the clamping rod 3, so that the two clamping blocks 2 can be installed on the same side of the clamping rod 3, thereby ensuring that the two clamping blocks 2 can be clamped into the foot holes of the two foot plates at the same time.

[0041] Preferably, as shown in Figures 1 to 3 , in the embodiment, the clamp body 1 can be a strip-shaped box body. The first side of the clamp body 1 can be an open side, and a receiving groove 10 is formed in the interior of the clamp body 1, and the foot plate of the main heater can be clamped in the receiving groove 10. The second side of the clamp body 1 (which can be the side opposite to the open side) can be a closed side, and the clamping rod 3 can be arranged on the closed side of the clamp body 1. Figure 3The upper side (as shown) can have a mounting groove 11. Specifically, the mounting groove 11 can be a strip-shaped groove provided along the length direction of the fixture body 1. The locking rod 3 can be inserted into the mounting groove 11, thereby mounting the locking rod 3 to the fixture body 1.

[0042] Furthermore, preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, connecting holes 12, which communicate with the receiving groove 10, can be provided at both ends of the mounting groove 11. The connecting holes 12 can be cylindrical holes. The diameter of the connecting holes 12 can be larger than the diameter of the clamping rod 3 and smaller than the diameter of the clamping block 2. This allows the bent portion 30 of the clamping rod 3 to extend into the receiving groove 10 through the connecting holes 12 and be threadedly connected to the clamping block 2, thereby simultaneously fixing the clamping rod 3 and the clamping block 2 to the clamp body 1. The clamping block 2 is fixed inside the receiving groove 10 for engaging with the foot plate hole.

[0043] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the receiving groove 10 can be a strip-shaped groove. Stepped portions 13 can be formed at both ends of the receiving groove 10 along its length inside the fixture body 1. The stepped portions 13 at both ends of the fixture body 1 can be symmetrically arranged to engage with foot plates of different models and sizes, allowing two foot plates to be simultaneously engaged with two stepped portions 13.

[0044] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the distance between the two stepped portions 13 can gradually decrease along the direction away from the opening of the receiving groove 10. That is, as... Figure 3 As shown, the stepped portion 13 has multiple steps formed from bottom to top to accommodate foot plates of various sizes. When the foot plate is large, it can be engaged near the opening of the groove in the stepped portion 13, while when the foot plate is small, it can be engaged near the bottom of the groove in the stepped portion 13. This allows for the foot plate to be positioned to prevent it from wobbling within the receiving groove 10.

[0045] In addition, preferred, such as Figure 2 and Figure 5As shown, in embodiments, the clamping block 2 can include a rod-shaped portion 21 and a flexible clamping member 22. The rod-shaped portion 21 can be a cylindrical rod. The top end of the rod-shaped portion 21 can be integrally formed with the stud 20, so that the top end of the rod-shaped portion 21 can be connected with the end of the clamping rod 3. The bottom end of the rod-shaped portion 21 can be formed with a spherical surface, so as to be easily inserted into the foot plate hole of the foot plate. The axial direction of the rod-shaped portion 21 can be perpendicular to the plate surface of the foot plate. The flexible clamping member 22 can be formed on the rod-shaped portion 21. The number of the flexible clamping member 22 can be multiple, and the multiple flexible clamping members 22 can be arranged at intervals along the axial direction of the rod-shaped portion 21. Preferably, the side of the flexible clamping member 22 facing the main heater can be formed as an arc surface, so as to be easily clamped into the foot plate hole of the foot plate. In addition, the diameters of the multiple flexible clamping members 22 can gradually increase in a direction away from the main heater (i.e., gradually increase from bottom to top as shown by the flight path), so that the clamping block 2 can cooperate with foot plates of multiple models, thereby adapting to foot plate holes of different sizes. Figure 2

[0046] Further preferably, in embodiments, the clamp body 1 can be made of polyethylene pearl wool material, so as to avoid collision between the clamp body 1 and the foot plate and to buffer the impact received by the clamp body 1. The clamping block 2 can be made of rubber polyethylene material, so that the flexible clamping member 22 of the clamping block 2 can be deformed to be clamped into the foot plate hole of the foot plate and to limit the foot plate. The clamping rod 3 can be a stainless steel rod, so as to ensure the hardness of the clamping rod 3 and to avoid change of the distance between the two clamping blocks 2 due to deformation of the clamping rod 3, thereby improving the standardization of the fixing clamp for the main heater foot plate.

[0047] In addition, according to the second aspect of the present application, a main heater is provided, which includes a foot plate and a fixing clamp for a main heater foot plate as described above. The foot plate is provided with a foot plate hole. Two foot plates of the main heater can be clamped in the stepped portions 13 at the two ends of the accommodating groove 10, respectively. Two clamping blocks 2 are clamped in the foot plate holes of the two foot plates, respectively, so as to further position the foot plates.

[0048] In use, the fixing clamp for the main heater foot plate can achieve soft fixing of foot plates of different models and different sizes, and can protect against possible collisions. At the same time, the fixing clamp for the main heater foot plate is easy to use, and only needs to be directly inserted into the foot plate hole. The fixing clamp for the main heater foot plate is highly standardized and is not easy to deform, and can effectively help the main heater to maintain a standard form.

[0049] ​Finally, it should be noted that the above-described embodiments are merely specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the same. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that any skilled person in the art can still modify or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features, within the technical scope disclosed by the present application.
