Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically a high-sealing air valve temperature sensor. Background Technology

[0002] Air volume regulating valves (or simply air valves) are indispensable central air conditioning terminal accessories in ventilation, air conditioning, and air purification projects in industrial plants and civil buildings. They are generally used on air conditioning and ventilation system ducts to regulate the air volume of branch pipes. The temperature sensors installed on air valves are mostly assembled from several molded parts, resulting in poor sealing. At the same time, when the wiring harness connected to the temperature sensor is long, it is prone to loosening during transportation and storage. Loose wiring harnesses can lead to tangling or contact with other components, causing damage and causing inconvenience to operators, thus hindering widespread adoption. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-sealing air valve temperature sensor, which solves the problems of loose wiring harnesses being difficult to store and transport.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing air valve temperature sensor, comprising a body, a sealing ring fixedly disposed on the outer side of the body, and two sets of sealing rings fixedly disposed inside the body, a connecting block bolted to the right side of the body, a horizontal plate tightly fastened to the right side of the connecting block, two sets of locking blocks slidably connected inside the horizontal plate, a bearing tightly fastened inside the connecting block, a threaded tube tightly fastened to the middle of the bearing, the right end of the threaded tube penetrating the connecting block and the horizontal plate and fastened to the handle, a sleeve screwed onto the outer side of the threaded tube, a support plate tightly fastened to the top and bottom of the sleeve, and the side of the support plate away from the sleeve being movably locked inside the locking block.

[0005] Preferably, the sealing ring is a high-temperature resistant rubber sealing ring.

[0006] Preferably, a fixing plate is fixedly attached to the top and bottom of the horizontal plate, a slider is fixedly attached to the top of the locking block, and a spring is fixedly attached between the slider and the fixing plate.

[0007] Preferably, a limit rod is fastened to the right side of the fixing plate, and the slider is slidably connected to the outside of the limit rod.

[0008] Preferably, a buffer pad is tightly fitted to the outer side of the limiting rod, and the buffer pad is located on the right side of the slider.

[0009] Preferably, two sets of balance bars are tightly fitted inside the cross plate, and the support plate is slidably connected to the outside of the balance bars.

[0010] Compared with the prior art, this utility model provides a high-sealing temperature sensor for a damper, which has the following advantages:

[0011] 1. This high-sealing air valve temperature sensor achieves a sealing effect by adding sealing rings inside and outside the device body, thus avoiding poor sealing. By incorporating easily detachable connecting blocks and cross plates, the wire harness can be wound around the outside of the connecting block during storage or transportation. At the same time, the movable locking block can block the wire harness after it has been wound, thereby preventing the loose wire harness from becoming entangled or coming into contact with other components and causing damage. This brings convenience to the operator and is suitable for widespread application.

[0012] 2. This high-sealing air valve temperature sensor incorporates a spring. When the support plate pushes the locking block to move, the spring is compressed by the slider. When the support plate moves back and no longer pushes the locking block, the spring will bounce the slider back, causing the locking block to move back. This allows the locking block to quickly return to its initial position and no longer obstruct the wire harness, thus facilitating the operator's work with the wire harness. Furthermore, the spring is inexpensive and suitable for widespread application. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4The utility model provides a technical scheme: a kind of high airtightness air valve temperature sensor, the outside of body 1 is fixedly arranged with sealing ring 5, and inside body 1 is fixedly arranged with two groups of sealing ring 5, sealing ring 5 is high-temperature-resistant rubber sealing ring, the right side bolt connection of body 1 has connecting block 3, the right side of connecting block 3 is fastened with crosspiece 4, the inside of crosspiece 4 is slidably connected with two groups of clamping block 8, the inside of connecting block 3 is fastened with bearing, the middle part of bearing is fastened with threaded tube 10, the right end of threaded tube 10 penetrates connecting block 3 and crosspiece 4 and is fastened with handle 7, threaded tube 10 is outside screw-grooved with sleeve 9, the top and bottom of sleeve 9 are fastened with support plate 15, and support plate 15 is fastened in the inside of clamping block 8 on the side away from sleeve 9, by being additionally equipped with sealing ring 5 in body 1, to reach sealing effect further, avoid the case that sealing property is poor, and by being equipped with the connecting block 3 and crosspiece 4 that can be conveniently disassembled, further, in the process of keeping or transportation, wire harness can be wound on the outside of connecting block 3, and movable clamping block 8 can block wire harness after winding, so as to avoid the case that loose wire harness leads to wire harness winding or contact with other components to cause damage, facilitate the work of operator, and be suitable for promotion.

[0020] Specifically, in order to make the clamping block 8 quickly return, the top and bottom of the crosspiece are fastened with the fixed plate, the top of the clamping block is fastened with the sliding block, and the sliding block and the fixed plate are fastened with the spring. Thus, by setting the spring 12, when the support plate 15 moves the clamping block 8, the spring 12 will be squeezed by the sliding block 13. When the support plate 15 returns and no longer moves the clamping block 8, the spring 12 will drive the clamping block 8 to return by the way of bouncing the sliding block 13. Thus, the clamping block 8 can quickly return to the initial position and no longer block the wire harness, which facilitates the operator to use the wire harness and the spring 12 is low in cost, suitable for promotion.
