Description

Technical Field

[0001] This utility model relates to the technical field of PTC heater mounting structure, and in particular to a PTC heater support mounting structure. Background Technology

[0002] The PTC heater mounting structure refers to the sum of all mechanical supports, fixation, heat dissipation, protection, electrical connections, and interface components designed to safely, reliably, and efficiently integrate the PTC heating element into the final application equipment or system. It is the bridge connecting the PTC heating element to the outside world.

[0003] The existing publication number CN212137943U, entitled "A Novel PTC Electric Heater Support Base", describes a device that uses a threaded shaft to enter the interior of two threaded holes. A retaining pin fixed on the end face of the threaded shaft then enters a slot corresponding to the second threaded hole, thereby fixing the turntable. This device enables the present invention to firmly fix the PTC electric heater and prevent the PTC electric heater from becoming loose.

[0004] However, the aforementioned patent requires the operation of multiple threaded rods to clamp and fix the heater, ultimately driving the rubber block structure to clamp the heater, which results in a rather cumbersome fixing process. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a support and mounting structure for a PTC heater.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a PTC heater support and installation structure, including a mounting frame, two force springs are fixedly connected to the inner bottom wall of the mounting frame, a lifting plate is fixedly connected to the top of the two force springs, two sets of guide blocks are fixedly connected to the upper surface of the lifting plate, and each set of guide blocks has two blocks. A clamping assembly is provided inside the mounting frame.

[0007] Preferably, the clamping assembly includes two movable plates, each movable plate having two sets of rectangular blocks slidably connected inside, each set of rectangular blocks having two one-way bearings rotatably connected to its inner wall, each set of rectangular blocks having two one-way bearings, and each set of one-way bearings having a one-way rotating shaft rotatably connected to its inner ring.

[0008] Preferably, each of the movable plates has a fixed block fixedly connected to its front and back sides, a rotating shaft is rotatably connected to the inner wall of each fixed block, and a rotating cylinder is fixedly connected to the outer surface of each rotating shaft.

[0009] Preferably, the mounting bracket has sliding grooves on both the front and back sides, and each rotating cylinder is slidably connected inside the sliding groove.

[0010] Preferably, each of the movable plates has a roller rotatably connected to its inner wall, and the outer surface of each guide block is in contact with the outer surface of the roller.

[0011] Preferably, each of the movable plates has two sets of T-shaped grooves on its outer surface, with two T-shaped grooves in each set. Each T-shaped groove has a T-shaped slider slidably connected inside it. The side of each T-shaped slider near the rectangular block is fixedly connected to the side of the rectangular block near the T-shaped slider. Each movable plate has two short shafts rotatably connected to its inner wall. One end of each short shaft is fixedly connected to a limiting plate. The outer surface of each limiting plate is in contact with the outer surface of the rectangular block.

[0012] The advantages and beneficial effects of this utility model are: This utility model is equipped with a lifting plate and a guide block. When the PTC heater is installed, the PTC heater will contact the upper surface of the lifting plate, and the pressure applied to the PTC heater will act on the lifting plate, thereby driving the lifting plate and the guide block to move downward. The downward movement of the guide block will provide clamping power for the clamping assembly.

[0013] This invention incorporates one-way bearings and one-way rotating shafts. After the moving plate is guided by the guide block to the position of the PTC heater, the surface of the one-way rotating shaft contacts the surface of the PTC heater. The surface of the one-way rotating shaft is covered with a layer of rubber. Utilizing the high coefficient of friction of rubber, the friction between the PTC heater and the one-way rotating shaft is increased. Furthermore, under the action of the one-way bearings, the two one-way rotating shafts on the left can only rotate clockwise, while the two one-way rotating shafts on the right can only rotate counterclockwise. Thus, when the one-way rotating shafts are in close contact with the surface of the PTC heater, the two sets of one-way rotating shafts can jointly restrict the upward movement of the PTC heater, thereby providing a stable clamping force for the PTC heater.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1 to 4 As shown, a PTC heater support and mounting structure includes a mounting bracket 1. Two force springs 7 are fixedly connected to the inner bottom wall of the mounting bracket 1. The force springs 7 store energy when compressed through a tightly coiled spiral. When the PTC heater is disassembled, the force springs 7 can provide a certain thrust to it.

[0018] The top ends of the two force springs 7 are fixedly connected to the lifting plate 2. The lifting plate 2 slides inside the mounting frame 1, and the surface of the lifting plate 2 contacts the inner wall of the mounting frame 1. When the lifting plate 2 is subjected to the pressure during the installation of the PTC heater, it can transmit the power to the force spring 7 and store the power through the force spring 7.

[0019] Two sets of guide blocks 3 are fixedly connected to the upper surface of the lifting plate 2. Each set of guide blocks 3 consists of two blocks. The side of the guide block 3 closest to the lifting plate 2 is designed with an incline. The incline design can be used to push the structure below the guide block 3 to move towards the PTC heater.

[0020] The mounting bracket 1 is equipped with a clamping component 4 inside.

[0021] The clamping assembly 4 includes two movable plates 401. After being pushed by the guide block 3, the movable plates 401 move towards the PTC heater, providing a certain clamping force for the installation of the PTC heater.

[0022] Each movable plate 401 has two sets of rectangular blocks 403 slidably connected inside, and the rectangular blocks 403 slide inside the movable plate 401.

[0023] Each set of rectangular blocks 403 has two one-way bearings 404 rotatably connected to its inner wall. There are two rectangular blocks 403 and two one-way bearings 404 in each set. The inner ring of each set of one-way bearings 404 is rotatably connected to a one-way rotating shaft 402. The one-way bearings 404 can restrict the one-way rotating shaft 402 to rotate in only one direction. The two sets of one-way rotating shafts 402 can jointly restrict the PTC heater from moving upward, thereby providing a stable clamping force for the PTC heater.

[0024] Each movable plate 401 has a fixed block 11 fixedly connected to its front and back sides. Each fixed block 11 has a rotating shaft 10 rotatably connected to its inner wall. Each rotating shaft 10 has a rotating cylinder 8 fixedly connected to its outer surface. The rotating shaft 10 and rotating cylinder 8 rotating on the inner wall of the fixed block 11 can reduce the friction force experienced by the movable plate 401 when it moves.

[0025] The mounting bracket 1 has sliding grooves 9 on both the front and back. Each rotating cylinder 8 is slidably connected inside the sliding groove 9. The sliding groove 9 can limit a certain distance of the rotating cylinder 8.

[0026] Each movable plate 401 has a roller 12 rotatably connected to its inner wall, and the outer surface of each guide block 3 is in contact with the outer surface of the roller 12. The roller 12 can reduce the friction force experienced by the movable plate 401 when it contacts the guide block 3.

[0027] Each movable plate 401 has two sets of T-shaped grooves 6 on its outer surface, with two T-shaped grooves 6 in each set. A T-shaped slider 5 is slidably connected inside each T-shaped groove 6. The side of each T-shaped slider 5 near the rectangular block 403 is fixedly connected to the side of the rectangular block 403 near the T-shaped slider 5. Two short shafts 14 are rotatably connected to the inner wall of each movable plate 401. A limit plate 13 is fixedly connected to one end of each short shaft 14. The outer surface of each limit plate 13 is in contact with the outer surface of the rectangular block 403. The T-shaped slider 5 slides inside the T-shaped groove 6, which can limit the movement distance of the rectangular block 403. The short shafts 14 and the limit plate 13 can limit the position of the rectangular block 403, making it convenient to disassemble the rectangular block 403.

[0028] Working Principle: When this device is needed, the PTC heater to be installed is placed on the surface of the lifting plate 2, and a downward thrust is applied to the PTC heater. When the lifting plate 2 moves downward under the thrust, it will compress the force spring 7 and pull the two sets of guide blocks 3 downward. When the guide blocks 3 move downward, the inclined surface design of the guide blocks 3 will push the two moving plates 401 closer to the position of the PTC heater until the one-way rotating shaft 402 inside the moving plate 401 contacts the surface of the PTC heater. The surface of the one-way rotating shaft 402 is covered with a layer of rubber. The high coefficient of friction of rubber can increase the friction between the PTC heater and the one-way rotating shaft 402. In addition, under the action of the one-way bearing 404, the two one-way rotating shafts 402 on the left can only rotate clockwise, while the two one-way rotating shafts 402 on the right can only rotate clockwise. Both can only rotate counterclockwise. When pressure is stopped on the PTC heater, the PTC heater will also be unable to move upward due to the limiting effect of the one-way rotating shaft 402. The inability of the PTC heater to move upward means that the lifting plate 2 cannot move upward. When it is necessary to disassemble the PTC heater, rotational power is applied to the two sets of limiting plates 13, so that the limiting plates 13 stop limiting the rectangular block 403. At this time, the rectangular block 403 and the one-way rotating shaft 402 can move to both sides and stop contacting the PTC heater. Thus, the purpose of releasing the limiting effect on the PTC heater can be achieved. Therefore, when the one-way rotating shaft 402 is in close contact with the surface of the PTC heater, the two sets of one-way rotating shafts 402 can jointly restrict the upward movement of the PTC heater, thereby providing a stable clamping force for the PTC heater and achieving the purpose of quickly installing the PTC heater.
