Description

Technical Field

[0001] The utility model relates to the technical field of door handles, in particular to a constant temperature door handle. Background Art

[0002] Door handles, also known as door handles and door handles, are devices used on doors, mainly used to open and close doors. It is not only one of the important accessories on the door, but also has decorative and functional functions.

[0003] The utility model patent with the authorization announcement number CN214886163U discloses a door handle with a heating function, which includes a handle body, wherein an automatic heating component is arranged inside the handle body; by arranging the automatic heating component, the temperature of water can be sensed by a temperature sensor during use and converted into usable output information, and the information is transmitted to a programmable PLC through an A / D converter for analysis; when the temperature is analyzed to be lower than a preset limit, the programmable PLC controls the operation of a heating rod and an electric motor through a D / A converter at the same time, and the heating rod starts to heat the water, and at the same time, the electric motor drives the reciprocating screw to rotate, and through the threaded connection between the circular sleeve and the reciprocating screw, the circular sleeve performs a rotational lifting motion on the reciprocating screw, driving a plurality of stirring paddles to continuously stir the water, thereby achieving rapid heating, and effectively solving the problem that when the external temperature of the existing metal door handle is low, the temperature of the existing metal door handle itself will also be very low, and the touch will be cold, making people feel cold and uncomfortable, and most of the existing heated door handles still have the problems of slow heating and low degree of automation when in use.

[0004] Although the door handle with heating function has the function of heating the door handle, the device still has the following problems in actual use: the device heats the door handle through a heating rod and an electric motor, and the heating rod and the electric motor are installed inside the handle body. At the same time, a programmable PLC is also provided in the door handle body, so that more structures are integrated in the door handle body, which makes the production and assembly of the handle more difficult and has a high failure rate; at the same time, the device achieves rapid heating through the reciprocating rotation of the reciprocating screw and the lifting and lowering of the stirring paddle, which not only increases the energy consumption of the equipment, but also has an unsatisfactory heating effect. In view of this, we propose a constant temperature door handle. Utility Model Content

A slide plate 29 is slidably installed between the two guide rods 27, and a spring 28 for pressing the slide plate 29 is sleeved on the guide rods 27. The two end faces of the two slide plates 29 that are separated from each other are installed with clamping heads 291, and the clamping heads 291 are fixedly connected to the slide plate 29 by bolts. The slide plate 29 passes through the outer wall of the handle 20; a detachable mounting part 3 is installed at the upper and lower sides of the handle 20, and the mounting part 3 includes a mounting head 30, and the two opposite end faces of the two mounting heads 30 are provided with a fixing groove 301 that is plugged and matched with the end of the handle 20, and a slot 302 is provided on one side wall of the fixing groove 301, and two symmetrical clamping grooves 303 are provided on the inner wall of the slot 302; a hollow connecting rod 31 is installed on the outer wall of the mounting head 30, and the end of the connecting rod 31 is detachably connected to the mounting seat 1. The plug board 26 is plugged into the slot 302 , and the clamp head 291 is clamped into the corresponding clamping slot 303 .

[0032] In this embodiment, thread grooves are provided at both ends of the handle 20, and the connector 25 is threadedly connected to the thread grooves. This design facilitates the disassembly and assembly of the connector 25, and further facilitates the later inspection and maintenance of the interior of the handle 20.

[0033] In this embodiment, a mounting ring 32 is installed at the end of the connecting rod 31, and a plurality of mounting holes for passing bolts to connect the mounting seat 1 are opened on the mounting ring 32.

[0037] It should be added that when the temperature sensor 24 detects that the temperature in the heating chamber 201 is lower than the threshold value, the temperature sensor 24 sends a signal to the controller 11, and the controller 11 controls the wire 23 to be connected to the power supply. At this time, the electric heating tube 21 is energized and generates heat, and the electric heating tube 21 simultaneously heats the water source in the heating chamber 201. The water source is heated, and when the temperature of the water source is transmitted to the handle 20, the handle 20 heats up; when the temperature sensor 24 detects that the temperature in the heating chamber 201 reaches the threshold value, the temperature sensor 24 sends a signal to the controller 11, and the controller 11 disconnects the wire 23 from the power supply.

[0038] When in use, the user first connects the power supply of the wire 23, and the electric heating tube 21 is energized. At this time, the electric heating tube 21 is energized and generates heat, and the electric heating tube 21 simultaneously heats the water source in the heating chamber 201. The water source is heated, and when the temperature of the water source is transmitted to the handle 20, the handle 20 is heated;

[0039] When the mounting portion 3 needs to be removed, the user first squeezes the clamping heads 291 on both sides of the mounting head 30 inward. The clamping heads 291 are squeezed and drive the slide plate 29 to slide along the two guide rods 27, and the spring 28 is compressed. When the clamping heads 291 are retracted into the cavity 261, the user pushes the mounting head 30 to one side. At this time, the plug plate 26 is disengaged from the slot 302, and the mounting head 30 on one side is removed. Repeat the above steps to remove the mounting head 30 on the other side.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
