[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides an adjustable pre-tightening automobile PTC electric heater, comprising:

[0025] The housing 1 has a cover plate 2 rotatably disposed on the top of the housing 1. A fixing block is fixedly disposed on one side of the housing 1 and the cover plate 2. Through holes are penetrated through the fixing blocks. The fixing blocks at both ends can be fixed together by bolts and nuts, thereby fixing the housing 1 and the cover plate 2.

[0026] Two heat conducting blocks 3 are fixedly arranged in parallel in the housing 1. The inner sides of the two heat conducting blocks 3 are provided with a limiting assembly. The limiting assembly includes a plurality of positioning blocks 4 and a plurality of clamping blocks 6. The plurality of positioning blocks 4 are as follows: Figure 2 As shown, the two heat conducting blocks 3 are fixedly mounted on the inner top ends thereof, and the plurality of positioning blocks 4 are provided with clamping holes 5, and the plurality of clamping blocks 6 are provided with Figure 2 As shown, the plurality of positioning blocks 4 and the plurality of clamping blocks 6 are respectively fixedly arranged at the inner bottom ends of the two heat conducting blocks 3, and are linearly evenly distributed. A plurality of U-shaped frames 7 are arranged between the two heat conducting blocks 3, and the plurality of U-shaped frames 7 are staggeredly matched with the plurality of positioning blocks 4 and the plurality of clamping blocks 6, so that the U-shaped frame 7 can be inserted between the two positioning blocks 4, and can also be inserted between the two clamping blocks 6, so as to position the U-shaped frame 7;

[0027] A heating assembly is disposed on each of the plurality of U-shaped frames 7. The heating assembly includes a plurality of heating plates 8, two conductive plates 9 and a clamping plate 12. The plurality of heating plates 8 are as follows: Figure 3 As shown, the plurality of heating plates 8 are evenly distributed in a rectangular shape, and are all arranged in the U-shaped frame 7 and are arranged against the inner wall of the U-shaped frame 7. The two conductive plates 9 are arranged against the two sides of the U-shaped frame 7. The inner sides of the two ends of the clip 12 are arranged against the outer sides of the two conductive plates 9. The top of the clip 12 is penetrated with a connection hole, and the connection hole allows the contact points of the two conductive plates 9 to be exposed. The clip 12 is arranged in an n-type, and the clip 12 is set to a heat-conducting material and has a certain elasticity. Clamping grooves 19 are arranged on both sides of the clip 12. The clamping grooves 19 facilitate the staff to pull out the clip 12, thereby pulling out the U-shaped frame 7, which is convenient for maintenance and replacement;

[0028] The bottom ends of both sides of the clip 12 are penetrated with positioning holes 13, and the bottom ends of both sides of the U-shaped frame 7 are fixedly provided with two positioning posts 10. The outer sides of the four positioning posts 10 are all inclined, so that when the bottom ends of the clip 12 squeeze the inclined surfaces of the four positioning posts 10, the four positioning posts 10 can push the bottom ends of the clip 12 outward, and the four positioning posts 10 are matched with the positioning holes 13 on the same side, so that the four positioning posts 10 can be respectively inserted into the positioning holes 13 on the same side. The four positioning posts 10 are all provided with card slots 11, and the four card slots 11 are matched with the conductive sheet 9 on the same side, so that the bottom two corners of the conductive sheet 9 can be inserted into the card slots 11 on the same side, thereby positioning the conductive sheet 9, which is convenient for the staff to install;

[0029] Positioning components are provided between the two ends of the multiple U-shaped frames 7 and the heat-conducting blocks 3 on the same side. The positioning components include a round rod 15, two sliders 16 and two spring sheets 17. A mounting hole 14 is penetrated on the U-shaped frame 7. The two ends of the round rod 15 are fixedly arranged on the inner top and inner bottom of the mounting hole 14 respectively. The round rod 15 penetrates the two sliders 16 for sliding. The two sliders 16 are slidably arranged against the inner wall of the mounting hole 14, so that the two sliders 16 can only slide up and down in the mounting hole 14 but cannot rotate. Two limit blocks 18 are fixedly provided on the round rod 15, and the two limit blocks 18 are arranged between the two sliders 16. The two ends of the two spring sheets 17 are fixedly arranged on both sides of the two sliders 16 respectively. The two spring sheets 17 are arranged in a V-shape, so that the outer sides of the two spring sheets 17 extend out of the mounting hole 14 and are clamped into the corresponding clamping holes 5.

[0030] The detailed working process of the utility model is as follows:

[0031] 1. During installation, the staff first places multiple heating sheets 8 in the U-shaped frame 7, then places two conductive sheets 9 against both sides of the U-shaped frame 7, and makes the bottoms be inserted into the card slots 11 on the same side for positioning, and at the same time, presses multiple heating sheets 8 tightly, and then sets the clip 12 on the outside of the two heating sheets 8, and then makes the bottoms of both ends of the clip 12 squeeze the inclined surfaces of the corresponding positioning columns 10, and the four positioning columns 10 push the bottom ends of both sides of the clip 12 outward, and when the four positioning holes 13 move to align with the corresponding positioning columns 10, the clip 12 resets under the action of its own elastic force, so that the four positioning holes 13 are set on the corresponding positioning columns 10, and the clip 12 is fixed, thereby fixing the heating sheet 8 and the two conductive sheets 9;

[0032] 2. Then, the staff will insert the two ends of the U-shaped frame 7 between the two positioning blocks 4 on the same side, and insert them between the corresponding two clamping blocks 6. At this time, the two positioning blocks 4 squeeze the spring pieces 17 on the same side, and the two spring pieces 17 will drive the upper slider 16 to move upward and stretch the two spring pieces 17. When the two spring pieces 17 move to align with the corresponding clamping holes 5, the two spring pieces 17 are reset under the action of their own elastic force and are clamped into the corresponding clamping holes 5, so that the U-shaped frame 7 can be fixed. The working process of the two spring pieces 17 at the other end is the same, and the installation process of multiple U-shaped frames 7 is the same;

[0033] 3. During disassembly, the staff pulls the clip 12 upwards, and the clip 12 drives the U-shaped frame 7 to move upwards through the four positioning columns 10, so that the two positioning blocks 4 squeeze the spring sheets 17 on the same side. The two spring sheets 17 will drive the slider 16 below to move downward and stretch the two spring sheets 17 to separate from the corresponding card holes 5. The working process of the two spring sheets 17 at the other end is the same. At this time, the U-shaped frame 7 can be pulled out, and then the bottom ends of both sides of the clip 12 are pried outwards to separate the four positioning holes 13 from the corresponding positioning columns 10, and then the clip 12 is removed, and the two conductive sheets 9 and multiple heating sheets 8 can be taken out for repair or replacement.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
