Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to a high-temperature resistant in-position switch transmission structure. Background Art

[0002] There are many types of switches, such as micro switches, electronic switches, laser switches, and inductive switches. Each of these switches has its own characteristics. However, they cannot be used in certain environments with high temperatures and strong sealing conditions. For example, stainless steel micro switches and ceramic micro switches are heat-resistant, but they are not suitable for use in conditions where the seal cannot be observed. Electronic switches, laser switches, inductive switches, etc. cannot be used in high-temperature sealed environments.

[0003] The internal temperature of a typical push plate and conveyor furnace can reach 650-950°C during operation. At this time, it is impossible to use ordinary switches to detect the arrival of products during processing in the furnace, which can cause production line stagnation and blockage, resulting in safety accidents, equipment damage, and personal injury.

[0004] Therefore, a high temperature resistant position switch transmission structure is needed. Utility Model Content

[0005] The main purpose of the utility model is to provide a high-temperature resistant in-position switch transmission structure. By using a detection rod made of stainless steel to extend into a high-temperature chamber, its plug-in section is arranged outside the high-temperature chamber, and a magnetic iron sheet is fixed on the plug-in section to cooperate with a magnetic induction switch arranged on the outside, after the product in the high-temperature chamber pushes the detection rod into position, the magnetic induction switch detects the magnetic iron sheet and transmits the in-position signal to the control system, thereby avoiding the problem of damage to the detection switch under high temperature during use, and the utility model is safe and reliable.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A high temperature resistant position switch transmission structure, comprising:

[0008] A fixing plate, wherein the fixing plate is provided with a through hole;

[0009] a sleeve, the sleeve being fixedly connected to a side surface of the fixing plate, the sleeve being coaxially arranged with the through hole;

[0010] The detection rod comprises a plug-in section and a protruding section, wherein the plug-in section is plugged and fixed to the through hole, the cross-sectional area of ​​the protruding section is larger than the area of ​​the through hole, and an elastic member is sleeved on the plug-in section, wherein one end of the elastic member abuts against the outer edge of the through hole and the other end abuts against the protruding section;

[0011] A magnetic induction switch is fixed to a side of the fixing plate away from the protruding section and is used to detect the magnetic sheet fixedly provided on the plug-in section.

[0012] Furthermore, the cross section of the sleeve is arranged to be polygonal, and the cross section of the protruding section matches the cross section of the sleeve.

[0013] Furthermore, an acrylic plastic cover tube is fixedly connected to a side of the fixing plate away from the protruding section, and the plug-in section is covered in the acrylic plastic cover tube.

[0014] Furthermore, the free end of the plug-in section is fixedly connected to a limiting block, and the magnetic sheet is fixedly connected to the limiting block.

[0015] Furthermore, a transversely arranged U-shaped groove is provided at the free end of the protruding section, and a roller is installed in the U-shaped groove.

[0016] Furthermore, the elastic member is a spring.

[0017] Furthermore, the detection rod is made of stainless steel.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. The utility model can fix the switch transmission structure outside the high-temperature chamber by setting a fixing plate, extend the detection rod into the high-temperature chamber, and by setting the detection rod into a plug-in section and a protruding section, the device at the position to be detected in the high-temperature chamber is squeezed by the protruding section, thereby causing the plug-in section to be displaced, so that the external magnetic induction switch can detect the magnetic sheet installed on the plug-in section, thereby detecting whether the interior is in place, and by sleeved with an elastic member on the plug-in section, the detection rod can be reset after the object in the high-temperature chamber leaves the protruding section.

[0020] Second, setting the casing cross section to a polygon can ensure that the protruding section can only move along the axial direction of the casing.

[0021] 3. By setting up the acrylic plastic cover tube cover connecting section, it is possible to avoid gas overflow from the high temperature chamber through the through hole of the fixed plate.

[0022] Fourth, by providing the limit block, it can be ensured that when the detection rod is reset under the action of the elastic member, the detection rod will not be separated from the sleeve as a whole.

[0023] 5. The roller can be set to facilitate the objects in the high temperature room to be easily separated from the detection rod. BRIEF DESCRIPTION OF THE DRAWINGS
