Description

Technical Field

[0001] This utility model relates to the field of regulator technology, and more particularly to thermal regulators. Background Technology

[0002] In the injection molding industry, the thermal controller is a core component for controlling the heating temperature of the mold, achieving precise temperature control by adjusting the heating power. Traditional thermal controllers typically consist of a PCB control module, a temperature adjustment knob, and a housing structure, with the housing often using screws to secure and encapsulate the internal components.

[0003] Existing thermal regulators typically use multiple sets of screws to secure the housing, requiring each screw to be loosened individually during disassembly, which is cumbersome and requires specialized tools. In addition, some housings use snap-fit ​​connections, which simplify disassembly, but repeated disassembly and reassembly can lead to wear on the snaps, resulting in decreased sealing or accidental disengagement. This significantly increases the time cost of PCB board repair or replacement, especially impacting production efficiency in emergency repair scenarios. To address these issues, this application proposes a thermal regulator. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a heat regulator. The bottom cover and top cover can be installed and removed through a detachable mechanism, which facilitates the maintenance of internal components and is simple to operate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat regulator includes a bottom cover, a top cover detachably connected to the bottom cover, a regulator PCB board fixedly connected to the top of the bottom cover, a connecting wire connected to the regulator PCB board, a knob installed on the top of the top cover, the connecting wire connected to the knob, two protrusions fixedly connected to the outer wall of the bottom cover, two grooves formed on the top cover, the two protrusions being inserted into corresponding grooves respectively, and a detachable mechanism between the bottom cover and the top cover.

[0007] Preferably, the detachable mechanism includes two first through holes on the side wall of the bottom cover, two second through holes communicating with the first through holes on the bottom cover, two through openings on the top cover, the two second through holes communicating with their corresponding through openings, a threaded groove on the top cover communicating with the two through openings, a fixing rod in each through opening, a fixing block fixedly connected to the side wall of each fixing rod, the fixing rod passing through the second through hole and the through opening, the fixing block being located in the first through hole, a threaded rod being installed on both fixing rods, and a cylinder being fixedly connected to the end of the threaded rod away from the fixing rod.

[0008] Preferably, the regulator PCB board is located inside the cavity.

[0009] Preferably, a raised strip is fixedly connected to the outer wall of the knob, and a numerical ring is fixedly connected to the top of the top cover.

[0010] Preferably, the outer wall of the threaded rod is provided with an external thread, and the inner wall of the threaded groove is provided with an internal thread that mates with the external thread.

[0011] Preferably, the front fixing rod has a through-hole, and the rear fixing rod has a limiting groove. The threaded rod passes through the through-hole and is inserted into the limiting groove.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The operator holds the cylinder and rotates it to rotate the threaded rod, causing the threaded rod to rotate and detach from the top cover. The operator then removes the two fixing rods and fixing blocks from the bottom cover, thus separating the bottom cover from the top cover. The adjuster PCB board on the bottom cover can then be inspected and replaced.

[0014] 2. By inserting the fixing rod and fixing block into the first through hole, the second through hole and the through opening, the fixing rod is inserted into the second through hole and the through opening, and the fixing block is inserted into the first through hole. Finally, the worker inserts the threaded rod into the threaded groove and rotates the threaded rod to insert it into the top cover. The threaded rod passes through the insertion opening and the end is inserted into the limiting groove in sequence, thus completing the limiting of the fixing rod and the fixing block.

[0015] In summary, the detachable mechanism allows for the installation and removal of the bottom and top covers, facilitating the inspection and maintenance of internal components and simplifying the operation. Attached Figure Description
