[0002] A special-shaped heating tube is a heating tube with an irregular shape, and is collectively called a special-shaped tube because of its irregular appearance. Common special-shaped infrared heating tubes include types such as U-shaped, ring-shaped, Q-shaped, frame-shaped, and C-shaped, and are commonly used in scenarios such as ovens, dryers, plastic welding, and deburring.

[0003] A heating tube is an element that can generate heat, usually made of materials such as metal tubes or ceramic tubes. Clamping and sealing means using a fixture to fix the heating tube in place. Clamping and sealing of special-shaped heating tubes refers to a process of fixing and sealing the heating tube with a fixture. This process is usually used in occasions where it is necessary to fix the heating tube and prevent heat dissipation, such as heating equipment, ovens, etc.

[0004] At present, during the operation of special-shaped heating tubes, most special-shaped heating tubes are directly installed in the installation groove, lacking a limiting and clamping structure for the special-shaped heating tubes, resulting in unstable installation and affecting the use of the special-shaped heating tubes. Therefore, it is necessary to propose a clamping and sealing device for special-shaped heating tubes to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a clamping and sealing device for special-shaped heating tubes, which has the characteristics of limiting and clamping the special-shaped heating tube from the left and right sides and the outer wall, and then the limiting structure and the clamping structure cooperate with each other to limit and fix the special-shaped heating tube, so as to realize stable clamping of the special-shaped heating tube.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A clamping and sealing device for special-shaped heating tubes, including a mounting plate, an installation groove is opened on the front end surface of the mounting plate, a groove is opened in front of the lower end surface of the installation groove, a special-shaped heating tube is installed inside the installation groove, the special-shaped heating tube includes two first bending parts, a second bending part and a straight tube part that are fixedly connected to each other, a limiting structure is detachably connected to the front end surfaces of the first bending part and the second bending part, the limiting structure includes a clamping ring clamped on the outer walls of the first bending part and the second bending part, one end of the outer wall of the clamping ring is fixedly connected with a round rod, the other end of the clamping ring is fixedly connected with a positioning block, and a positioning groove matching with the positioning block is opened on the front end surface of the mounting plate;

[0007] Two groups of clamping structures are fixedly connected inside the installation groove, and the clamping structures include two clamping blocks respectively located on the outer walls of the lower ends of the straight tube part.

[0008] In order to improve the effect of stably clamping the special-shaped heating tube, as an optimization of the special-shaped heating tube clamping and sealing device of the present utility model, a fixing plate is installed on the front end face of the mounting plate, and a limiting arc plate clamped on the outer wall of the straight tube part is fixedly connected to one side of the fixing plate close to the special-shaped heating tube.

[0009] In order to limit and fix the positioning block and the mounting plate, as well as the fixing plate and the mounting plate, as an optimization of the special-shaped heating tube clamping and sealing device of the present utility model, the positioning block and the mounting plate, as well as the fixing plate and the mounting plate, are all connected by bolts.

[0010] In order to insulate the clamping ring and the limiting arc plate, as an optimization of the special-shaped heating tube clamping and sealing device of the present utility model, insulating pads are installed on the inner walls of the clamping ring and the limiting arc plate.

[0011] In order to install the round rod on the mounting plate, as an optimization of the special-shaped heating tube clamping and sealing device of the present utility model, a round hole matching the round rod is opened on the front end face of the mounting plate.
