[0029] In order to better understand the purpose, structure and function of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] Embodiment, refer to Figures 1 to 6, this embodiment discloses a far-infrared carbon crystal heating plate that is easy to assemble, including a housing 1 and a heating element 2. The housing 1 is a hollow structure with an open front. A circular through-hole 101 is provided in the upper part of the housing 1. A partition 102 is fixedly arranged horizontally inside the housing 1. The partition 102 is provided with a circular through-hole 2. The inner diameters of the circular through-hole 101 and the circular through-hole 2 are the same. A cylindrical connecting column 103 is fixedly connected between the circular through-hole 101 and the circular through-hole 2. The inner diameter of the cylindrical connecting column 103 is larger than the inner diameters of the circular through-hole 101 and the circular through-hole 2. A pressing rod 3 is arranged inside the cylindrical connecting column 103. The outer diameter of the pressing rod 3 is the same as the inner diameters of the circular through-hole 101 and the circular through-hole 2. A limiting convex strip 301 is arranged circumferentially along the outer wall of the pressing rod 3. The outer diameter of the limiting convex strip 301 is the same as the inner diameter of the cylindrical connecting column 103. A spring 302 is fixedly connected to the bottom of the limiting convex strip 301. The spring 302 is sleeved on the pressing rod 3. The inner diameter of the spring 302 is larger than the inner diameter of the circular through-hole 2. A hinge block 304 is fixedly connected to the bottom of the pressing rod 3. The hinge block 304 is located below the partition 102. Push rods 305 are respectively hinged to the left and right sides of the hinge block 304. Clamping rods 306 are respectively hinged to the ends of the two push rods 305. The hinging method is hole-shaft hinging. A limiting slider 307 is arranged at the bottom of the clamping rod 306. A linear straight chute 104 that matches the limiting slider 307 is provided at the bottom of the housing 1. The limiting slider 307 is located inside the linear straight chute 104. Press the pressing rod 3, the push rods 305 move to both sides, driving the clamping rods 306 to move to both sides. Due to the limitation of the position of the limiting slider 307 by the linear straight chute 104, the clamping rods 306 always remain vertical. At this time, the heating element 2 is placed inside the housing 1, at the middle position between the two clamping rods 306. Release the pressing rod 3. Under the action of the spring 302, the pressing rod 3 is lifted, pulling the push rods 305 to move towards the middle, and then driving the two clamping rods 306 to move towards the middle to clamp the heating element 2 and fix it.

[0031] The circular through-hole 101 is located at the center of the upper horizontal plate of the housing 1. The circular through-hole 2 is located at the center of the partition 102. The centers of the circular through-hole 101 and the circular through-hole 2 are on the same vertical line. This makes the pressing rod 3 move more smoothly during the movement, and can make the heating element 2 be clamped in the middle position, with uniform force on both sides, and will not cause damage to the heating element 2.

[0032] The push rod 305 is axially hinged to the hinge block 304. The upper part of the push rod 305 is relatively provided with a hinge shaft 3051. The length of the hinge shaft 3051 exceeds the edge of the hinge block 304. A limiting strip 105 is fixedly arranged horizontally in the housing 1. The limiting strip 105 is located below the partition 102. A through slot 1051 is provided in the middle of the limiting strip 105. Opposite sliding slots 1052 adapted to the hinge shaft 3051 are provided in the through slot 1051. Through the cooperation of the hinge shaft 3051 and the sliding slot 1052, the driving force of the push rod 305 on the clamping rod 306 is kept in the horizontal direction, making the translation of the clamping rod 306 smoother.

[0033] A shielding plate 4 is provided at the opening formed by the limiting strip 105 and the upper part of the housing 1, which can shield other parts inside the housing 1 except the heating element 2, achieving the effects of beauty and protecting the internal components.

[0034] Sliding strips 401 are provided at both ends of the shielding plate 4. Vertical sliding grooves 106 adapted to the sliding strips 401 are provided on the two side plates of the housing 1, facilitating the disassembly of the shielding plate 4 for the maintenance of the internal components.

[0035] Assembly holes 107 are arrayed on the back vertical plate of the housing 1 for fixing the far-infrared carbon crystal heating plate on the wall.

[0036] A wire passing through hole 108 is provided at the bottom of the housing 1. The wires connected to the heating element 2 can pass through the wire passing through hole 108 to be connected to an external power supply to supply power to the far-infrared carbon crystal heating plate.

[0037] A pressing block 303 is provided at the top of the pressing rod 3. The pressing block 303 is located outside the housing 1. The outer diameter of the pressing block 303 is larger than the inner diameter of the circular through hole 101. The pressing block 303 facilitates the operator's pressing operation on the pressing rod 3 and does not allow the pressing rod 3 to be pressed into the cylindrical connecting column 103.

[0038] A buffer pad 3061 is provided on the contact surface between the clamping rod 306 and the heating element 2, playing a protective role for the heating element 2.

[0039] Working principle: Press the pressing rod 3, and the pushing rod 305 moves towards both sides, driving the clamping rods 306 to move towards both sides. Due to the restriction of the position of the limiting slider 307 by the linear straight sliding groove 104 and the cooperation between the hinge shaft 3051 and the sliding groove 1052, the clamping rods 306 always remain perpendicular. At this time, place the heating element 2 inside the housing 1, at the middle position between the two clamping rods 306. Release the pressing rod 3, and through the action of the spring 302, lift the pressing rod 3, pull the pushing rod 305 to move towards the middle, and then drive the two clamping rods 306 to move towards the middle to clamp the heating element 2 and fix it, eliminating the operation step of fixing the heating element 2 in the housing 1 with screws.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
