AI Technical Summary
When the existing plug-in thermostat is unstable with the temperature-controlled object, it may cause the thermostat to detach from the temperature-controlled object and cannot effectively control the temperature, resulting in a decrease in practical effect.
A plug-in thermostat is designed, including a box, a temperature controller body, a plug rod and a fixing mechanism. The fixing mechanism includes a bar, a slider, a tooth plate, a hard spring, a rotating shaft, a gear, a limit plate, a limit block, a limit slot, a moving slot, a displacement slot, a clamp and a tie rod. The tension of the hard spring causes the bar to move upward, causing the clamp to clamp and fix the temperature-controlled object to prevent the thermostat from falling.
By setting up hard springs and clamps, the thermostat and the temperature control object are stabilized to avoid falling, and the practical effect of the thermostat is improved. The structures such as limit tabs, limit blocks and limit slots ensure the correct position and rotation of the gears and bars, preventing offsets and falls.

[0002] A thermostat refers to a series of automatic control components that produce certain special effects and conduction or disconnection actions by physically deforming the inside of the switch according to the temperature changes in the working environment. It is also called a temperature control switch, temperature protector, temperature controller, or simply a thermostat. Alternatively, the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy-saving effect.
[0003] Thermostats have a wide range of applications. Different types of thermostats are used in many products such as home appliances, motors, refrigeration or heating, including plug-in thermostats. Although existing plug-in thermostats have the characteristic of convenient temperature control, when the heating device is inserted into the object to be temperature-controlled, if the whole cannot be fixed to the object to be temperature-controlled, the thermostat may be unstable with the object to be temperature-controlled, causing the thermostat to separate from the object to be heated, thereby making it impossible for the thermostat to effectively control the temperature of the object to be temperature-controlled, thereby reducing the practical effect of the thermostat.
[0004] Therefore, those skilled in the art provide an insertion type thermostat to solve the problems raised in the above background technology. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-4, an insertion type temperature controller, comprising a box body 1, a temperature controller body 3 is fixedly installed at the bottom of the box body 1, and an insertion rod 4 is fixedly installed at the bottom of the temperature controller body 3;
[0025] A fixing mechanism 2 is provided at the bottom of the inner cavity of the box body 1, and the fixing mechanism 2 includes a polished rod 201, which is fixedly installed on the left and right sides of the bottom of the inner cavity of the box body 1, and a slider 202 is slidably connected to the outer surface of the polished rod 201, and a tooth plate 203 is fixedly installed on the left and right sides of the polished rod 201, and a hard spring 204 is fixedly installed on the left and right sides of the bottom of the polished rod 201, and the bottom of the hard spring 204 is fixedly installed on the bottom of the inner cavity of the box body 1, and the left and right sides of the rear side of the inner cavity of the box body 1 are movably connected with a rotating shaft 205 A gear 206 is fixedly installed on the outer surface of the rotating shaft 205, and the inner side of the gear 206 is meshed with the outer side of the toothed plate 203. Mounting plates 208 are fixedly installed on the front and rear sides of the gear 206. A vertical plate 209 is fixedly installed on the outer side of the mounting plate 208. A connecting rod 210 is fixedly installed on the bottom of the inner side of the vertical plate 209. A clamping block 213 is provided on the inner side of the connecting rod 210. Fixed rods 218 are fixedly installed on the left and right sides of the top of the light rod 201, and a pull rod 219 is fixedly installed on the top of the fixed rod 218.
[0026] Through the above technical solution, by setting the hard spring 204, the light rod 201 can be moved upward by its own tension, thereby avoiding the need to continuously apply force to the light rod 201, so that the gear 206 drives the clamping block 213 to clamp and fix the object to be temperature-controlled inward. By setting the clamping block 213, the temperature controller body 3 and the plug rod 4 can be easily fixed to the object to be temperature-controlled, avoiding the situation where the whole falls when the temperature of the object to be temperature-controlled is controlled.
[0027] Specifically, a limiting piece 207 is fixedly installed on the front side of the rotating shaft 205, and the limiting piece 207 is in a hexagonal shape.
[0028] Through the above technical solution, by setting the limiting plate 207, the gear 206 can be limited to prevent it from falling off from the front side of the rotating shaft 205 when rotating due to long-term work.
[0029] Specifically, both the front and rear sides of the inner cavity of the box body 1 are provided with limiting grooves 216 , and both the front and rear sides of the polished rod 201 are fixedly installed with limiting blocks 215 , which are movably connected in the inner cavity of the limiting grooves 216 .
[0030] Through the above technical solution, by setting the limit block 215 and the limit groove 216, the light rod 201 can be limited to avoid the deviation of its moving position, which makes the mounting plate 208 unable to rotate and the clamping block 213 unable to clamp inward.
[0031] Specifically, the left and right sides of the box body 1 are both provided with moving grooves 217 , and the mounting plate 208 passes through the inner cavity of the moving grooves 217 and extends to the outside of the box body 1 .
[0032] Through the above technical solution, by setting the movable groove 217, the mounting plate 208 can be limited to prevent it from shifting in the moving direction, so that the position where the clamp block 213 and the required temperature-controlled object are fixed to each other changes, and then the whole cannot be connected to the required temperature-controlled object.
[0033] Specifically, displacement grooves 220 are provided on both left and right sides of the top of the box body 1 , and the fixing rod 218 passes through the inner cavity of the displacement groove 220 and extends to the top of the box body 1 .
[0034] Through the above technical solution, by setting the displacement groove 220, the fixing rod 218 can be limited to avoid the movement position of the light rod 201 being synchronously shifted due to the shift of the fixing rod 218 when the fixing rod 218 is pulled to move.
[0035] Specifically, a screw groove 211 is formed on the inner side of the connecting rod 210 , and a threaded rod 212 is fixedly mounted on the outer side of the clamping block 213 . The threaded rod 212 is threadedly connected to the inner cavity of the screw groove 211 .
[0036] Through the above technical solution, by providing the screw groove 211 and the threaded rod 212, it is convenient to replace different types of clamps according to the shape or size of the object to be temperature-controlled.
[0037] Specifically, the inner side of the clamping block 213 is bonded with a protective pad 214 by PP glue, and the material of the protective pad 214 is rubber.
[0038] Through the above technical solution, by providing the protective pad 214, the object that needs to be temperature controlled can be protected to avoid damage to the object when it is clamped and connected.
[0039] The working principle of the utility model is as follows: the gripping pull rod 219 pushes the fixing rod 218 downward to drive the light rod 201 to move downward. Due to the movement of the light rod 201, the hard spring 204 is deformed due to the force, and the tooth plate 203 moves downward with the light rod 201. With the movement of the tooth plate 203, the gear 206 rotates, and the mounting plate 208 drives the upward flip movement. When the mounting plate 208 moves, the vertical plate 209 drives the connecting rod 210 and the clamping block 213 to flip upward synchronously, and then the whole is moved to the object to be temperature controlled, and the insertion rod 4 is inserted. Insert it into the object that needs temperature control, and then release the pull rod 219. At this time, due to the disappearance of force, the hard spring 204 is deformed again, and through its own tension, it pushes the light rod 201, the pull rod 219 and the fixed rod 218 to move upward. As the light rod 201 moves, the tooth plate 203 drives the gear 206 to rotate, and the mounting plate 208, the vertical plate 209, the connecting rod 210 and the clamping block 213 are flipped downward due to the rotation of the gear 206, so that the clamping block 213 clamps the object that needs temperature control, thereby completing the connection of the whole to the object that needs temperature control.
[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
