Description

Technical Field

[0001] This utility model relates to the field of thermal relay technology, and more specifically, to a thermal relay mounting base structure. Background Technology

[0002] A thermal relay is an electrical component that utilizes the heating effect of electric current. It consists of a heating element, a bimetallic strip, contacts, and a transmission and adjustment mechanism. The current flowing into the heating element generates heat, causing the bimetallic strip, which has different coefficients of expansion, to deform. When the deformation reaches a certain distance, it pushes a linkage to disconnect the control circuit, thereby de-energizing the contactor and disconnecting the main circuit, thus achieving overload protection for the motor. Thermal relays come in various types, including bimetallic strip type, fusible alloy type, thermistor type, and thermistor magnetic type. As an overload protection component for motors, thermal relays are widely used in production due to their small size, simple structure, and low cost. With the widespread use of thermal relays, more and more thermal relay mounting bases are also frequently used. Therefore, various types of thermal relay mounting bases have appeared on the market. However, the existing mounting base structure is not convenient for workers to protect the thermal relays. Utility Model Content

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0023] Example:

[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0025] Please see Figure 1-3This utility model provides a technical solution: a thermal relay mounting base structure, including a mounting plate 1, an adjusting chamber 2 fixedly connected to the surface of the mounting plate 1, a bearing fixedly connected inside the adjusting chamber 2 to allow a first rotating shaft 3 to pass through it, a transmission worm gear 4 fixedly connected to the surface of the first rotating shaft 3, and a threaded tube 5 passing through it. By setting the threaded tube 5 and the limiting screw 8, simply rotating the first rotating shaft 3 by turning the knob 19, with the cooperation of the transmission worm gear 4 and the transmission worm wheel 6, can move the limiting screw 8 inside the threaded tube 5 into the positioning groove 12, achieving the effect of protecting the thermal relay. The transmission worm wheel 6 is fixedly connected to the surface of the threaded tube 5, and the transmission worm gear 4 and the transmission worm wheel... The six-phase meshing is achieved by a limiting screw 8 passing through the inside of the threaded tube 5, with a connecting plate 7 fixedly connected to the top of the limiting screw 8. A protective shell 10 overlaps the surface of the mounting plate 1, and a positioning groove 12 is fixedly connected to the surface of the protective shell 10. The positioning groove 12 matches the limiting screw 8. A slider 11 is fixedly connected to the surface of the protective shell 10. A sliding groove 9 is opened on the surface of the mounting plate 1, and the slider 11 is movably connected inside the sliding groove 9. By setting the sliding groove 9 and the slider 11, the handle 15 can drive the protective shell 10 to move in a directional manner on the surface of the mounting plate 1, preventing the protective shell 10 from deviating during movement. A cable tray 13 is opened on the surface of the protective shell 10, and a handle 15 is fixedly connected to the surface of the protective shell 10.

[0026] By adopting the above technical solution, the protective shell 10 can be moved by the handle 15, and with the cooperation of the slide groove 9 and the slider 11, the protective shell 10 can be directionally moved on the upper surface of the mounting plate 1, so as to fit the protective shell 10 onto the surface of the thermal relay, thereby achieving the effect of protecting the thermal relay.

[0027] Specifically, there are two sets of slide grooves 9 and sliders 11, which are symmetrically arranged on the surface of mounting plate 1. There are multiple cable trays 13, which are evenly arranged on the surface of protective shell 10.

[0028] Specifically, the protective shell 10 has an observation window 14 embedded on its surface. The observation window 14 is made of transparent material, and the handle 15 has an anti-slip sleeve 16 on its surface. The anti-slip sleeve 16 is made of rubber material.

[0029] Specifically, the mounting plate 1 is fixedly connected to the side with fixing blocks 17. There are two sets of fixing blocks 17, which are symmetrically arranged on both sides of the mounting plate 1.

[0030] Specifically, the surface of the fixing block 17 is provided with threaded holes so that fixing bolts 18 can pass through it, and a knob 19 is fixedly connected to one end of the first rotating shaft 3.

[0031] The working principle of this utility model is as follows: When using this utility model, firstly, the device is moved to a suitable position, and then the position of the mounting plate 1 is fixed by the fixing bolt 18, thereby preventing the device from shifting during use. When the operator uses the device to install the thermal relay, the operator first installs and fixes the thermal relay on the surface of the mounting plate 1. Then, the operator moves the protective shell 10 by using the handle 15. With the cooperation of the sliding groove 9 and the slider 11, the handle 15 moves the protective shell 10 in a directional manner on the surface of the mounting plate 1, thereby preventing the protective shell 10 from shifting during the movement. When the positioning grooves 12 on the surfaces of the two protective shells 10 move to directly below the limiting screw 8, the operator stops pushing the protective shell 10. The operator then drives the first rotating shaft 3 to rotate by using the knob 19. Then, the first rotating shaft 3 drives the transmission worm wheel 6 to rotate through the transmission worm 4. At the same time, with the cooperation of the transmission worm 4 and the transmission worm wheel 6, the limiting screw 8 inside the threaded tube 5 moves into the interior of the positioning groove 12, thereby protecting the thermal relay.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
