DETAILED DESCRIPTION
[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] like Figure 1-6 A thermocouple protective cover shown in the figure includes a protective cover body 1, the protective cover body 1 includes a positive shell 2 and a secondary shell 21 separated in half, the butt joint portion of the positive shell 2 and the secondary shell 21 is provided with a groove 22, and a pinning component for connecting and locking the positive shell 2 and the secondary shell 21 is provided at the groove 22; the protective cover body 1 is equipped with a connecting sleeve 11, the upper end outer surface of the protective cover body 1 is provided with a first thread 23, the connecting sleeve 11 is threadedly connected to the first thread 23 part of the protective cover body 1, and the upper end outer surface of the connecting sleeve 11 is provided with a second thread 12 connected to the junction box base.
[0024] By dividing the protective cover body 1 into a main shell 2 and a secondary shell 21, the two parts can be disassembled to facilitate separation and replacement from the thermocouple. At the same time, through the setting of the pinning assembly and the connecting sleeve 11, the main shell 2 and the secondary shell 21 can be quickly fixed after docking, and then the second thread 12 on the connecting sleeve 11 is used to connect with the base part of the junction box, so that convenient installation can be achieved.
[0025] In one embodiment, the pinning assembly includes a pinning rod 3 that slides in an upper limit position on the auxiliary shell 21 and a pinning block 31 fixed to the bottom end of the main shell 2; a first pin joint 32 is provided at the bottom end of the pinning rod 3, and a first pinning hole 33 for the first pin joint 32 to be inserted is opened on the pinning block 31. Since the main shell 2 and the auxiliary shell 21 are separated as a whole from top to bottom, the gap after docking is long, and the connecting sleeve 11 can only fix the upper end part thereof, which makes it difficult to tighten the gap at the bottom. Therefore, the pinning rod 3 is provided, and the pinning block 31 at the bottom is pinned by the pinning rod 3, so that the upper and lower ends of the gap between the main shell 2 and the auxiliary shell 21 can be well fixed and sealed, thereby ensuring the stability of the overall structure.
[0026] In one embodiment, a limiting groove 4 is provided on the sub-shell 21, and a limiting slider 41 is provided on the pinning rod 3, which is slidably engaged with the limiting groove 4. Through the engaging structure between the limiting slider 41 and the limiting groove 4, the pinning rod 3 is limited to slide up and down on the sub-shell 21.
[0027] In one embodiment, a push convex plate 5 protruding away from the center side of the protective cover body 1 is provided on the pinning rod 3, and the push convex plate 5 abuts against the lower surface of the connecting sleeve 11. When the main shell 2 and the auxiliary shell 21 are docked, the upper part is connected to the connecting sleeve 11, thereby locking the connection part. When the connecting sleeve 11 is gradually rotated and sleeved on the outer surface of the protective cover body 1, it will abut on the push convex plate 5, thereby pushing the pinning rod 3 downward, so that the first pin joint 32 at its bottom end is inserted into the first pinning hole 33 and locked, thereby improving the stability of the pinning assembly.
[0028] In one embodiment, the protective cover body 1 is also provided with an alignment component for assisting the docking of the main shell 2 and the auxiliary shell 21; the alignment component includes a main alignment plate 6 arranged on the main shell 2 and a auxiliary alignment plate 61 arranged on the auxiliary shell 21; the main alignment plate 6 is provided with a recess 62 adapted to engage with the auxiliary alignment plate 61. Since the surfaces of the main shell 2 and the auxiliary shell 21 are provided with a first thread 23, it is necessary to ensure that the two are accurately aligned so that the connecting sleeve 11 can be rotatably connected with the outer surface of the protective cover body 1. Therefore, by providing the main alignment plate 6 and the auxiliary alignment plate 61, when the main shell 2 and the auxiliary shell 21 are docked, the auxiliary alignment plate 61 can be directly engaged with the recess 62 to achieve precise alignment, thereby improving the convenience of docking.
[0029] In one embodiment, a second pin joint 7 is provided on the lower surface of the push convex plate 5, and a second pinning hole 71 for the second pin joint 7 to be inserted is provided on the positive alignment plate 6. Through the arrangement of the second pin joint 7 and the second pinning hole 71, the middle section of the gap between the interface of the main shell 2 and the auxiliary shell 21 can also be locked, thereby further improving the structural stability of the assembly.
[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
