Description

Technical Field

[0001] This utility model relates to the field of heat insulation cover technology, specifically a heat insulation cover that can be installed quickly. Background Technology

[0002] The exhaust pipe of a car generates a lot of heat when the car is running. In order to prevent the parts under the car from aging or being damaged due to overheating, heat insulation devices need to be installed at the bottom of the car to insulate the heat. Current heat insulation devices include heat insulation cloth and heat insulation cover, which mainly use the material properties to reduce the adverse effects of heat on the parts.

[0003] In the prior art, a car heat shield with an installation structure, disclosed in CN 214035847 U, includes two U-shaped mounting rings. A heat shield is fixedly connected between the two U-shaped mounting rings. Square holes are provided on both sides of each U-shaped mounting ring, and U-shaped plates are fixedly connected to both sides of each U-shaped mounting ring. A screw is movably connected to each U-shaped plate. A knob is fixedly connected to one end of the screw, and a square threaded sleeve is provided at the other end of the screw. The square threaded sleeve is threadedly connected to the screw. This car heat shield with an installation structure, by setting a corrugated heat shield and setting U-shaped mounting rings at both ends of the heat shield, allows the clamping plate to be moved inward by turning the knob, which is beneficial for its installation on the exhaust pipe. The installation operation is convenient. Utilizing the shape characteristics of the corrugated pipe, it can be applied to exhaust pipes of different shapes and also has certain compensation characteristics, making it highly adaptable. Compared with customized heat shields, it is less expensive.

[0004] However, while this type of heat shield can be pressed and fixed well during use, the initial installation effect of directly fitting the heat shield onto the outer wall of the exhaust pipe is not good. Furthermore, when the heat shield is pressed and fixed using positioning blocks, the length of the positioning blocks is relatively fixed, which means that the length of the positioning blocks cannot be adjusted synchronously when installing heat shields of different lengths, thus reducing the flexibility of heat shield installation.

[0005] Therefore, in view of this, we studied and improved the existing structure to propose a quick-installation heat insulation cover. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-installation heat insulation cover to solve the problems mentioned in the background art, such as the poor initial installation effect of the heat insulation cover being fitted onto the outer wall of the exhaust pipe, and the relatively fixed length of the positioning block when the heat insulation cover is pressed and fixed by the positioning block, and the limited ability to synchronously adjust the length of the positioning block.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation heat insulation cover, comprising an exhaust pipe, a fixing frame fixedly connected to the outer wall of the exhaust pipe, a heat insulation cover body sleeved on the outer wall of the exhaust pipe, a left heat insulation cover fixedly connected to the side wall of the heat insulation cover body, a right heat insulation cover located on one side of the left heat insulation cover fixedly connected to the side wall of the heat insulation cover body, a first Velcro fastener fixedly connected to the outer wall of the left heat insulation cover, a second Velcro fastener adhered to the outer wall of the right heat insulation cover, a main positioning block slidably connected to the outer wall of the fixing frame and fitting against the surface of the heat insulation cover body, and a secondary positioning block detachably connected to the end of the main positioning block and fitting against the surface of the heat insulation cover body.

[0008] Furthermore, the outer wall of the fixing frame is provided with a nut, and the inner wall of the nut is threaded with a bolt that is rotatably connected to the outer wall of the main positioning block.

[0009] Furthermore, the outer wall of the main positioning block is fixedly connected with a first spring that is also fixedly connected to the outer wall of the fixing frame.

[0010] Furthermore, a sliding groove is provided at the connection between the outer wall of the fixing frame and the main positioning block. There are two sets of main positioning blocks, and the positions of the two sets of main positioning blocks are symmetrical about the central axis of the heat insulation cover.

[0011] Furthermore, a connecting box is fixedly connected to the outer wall of the main positioning block, and a plug rod that is slidably connected to the outer wall of the connecting box is fixedly connected to the outer wall of the secondary positioning block.

[0012] Furthermore, the insertion rod and the connecting box are misaligned about the central axis of the sub-positioning block.

[0013] Furthermore, the inner wall of the connecting box is slidably connected to a locking block that engages with the outer wall of the insertion rod, the outer wall of the locking block is fixedly connected to a telescopic rod that is slidably connected to the outer wall of the connecting box, the outer wall of the telescopic rod is sleeved with a second spring that is fixedly connected to the outer wall of the connecting box, and one end of the second spring is fixedly connected to a pull block that is fixedly connected to one end of the telescopic rod.

[0014] Furthermore, the outer wall contour of the connection between the main positioning block and the heat insulation cover is arc-shaped, and the outer wall contour of the connection between the secondary positioning block and the heat insulation cover is arc-shaped.

[0015] Furthermore, the outer wall contour of the initial pressing part of the card block and the insertion rod is inclined, and the engaging connection part of the card block and the insertion rod is planar.

[0016] Furthermore, a slot is provided at the connection point between the outer wall of the connecting box and the insertion rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The first Velcro and main positioning block of this utility model can, when the exhaust pipe of a car is used with the heat shield as an auxiliary device, improve the effect of double installation of the heat shield on the outer wall of the exhaust pipe by first fitting the left and right heat shields onto the outer wall of the exhaust pipe, making the first and second Velcros adhere to each other, and rotating the bolts through the limiting action of the nuts to make the main positioning block slide along the inner wall of the groove, pressing and fixing the outer wall of the heat shield, thereby achieving the effect of double installation and fixing of the heat shield on the outer wall of the exhaust pipe;

[0019] 2. The insert rod and locking block provided in this utility model can improve the adjustment and fixing effect of heat insulation covers of different lengths when positioning and installing the heat insulation cover through the main positioning block. The insert rod is inserted into the connecting box, and under the action of the initial pressing part of the insert rod and the locking block forming an inclined plane, the telescopic rod and the second spring are pressed until the locking part of the insert rod and the locking block are flat. Under the reaction action of the second spring being compressed, the locking block locks and fixes the insert rod, so that the main positioning block and the secondary positioning block can be locked and spliced ​​together to achieve the effect of adjusting and fixing heat insulation covers of different lengths.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1-6 As shown, a quick-installation heat insulation cover includes an exhaust pipe 1, a fixing bracket 2 fixedly connected to the outer wall of the exhaust pipe 1, a heat insulation cover body 3 sleeved on the outer wall of the exhaust pipe 1, a left heat insulation cover 4 fixedly connected to the side wall of the heat insulation cover body 3, a right heat insulation cover 5 located on one side of the left heat insulation cover 4 fixedly connected to the side wall of the heat insulation cover body 3, a first Velcro 6 fixedly connected to the outer wall of the left heat insulation cover 4, a second Velcro 7 that is adhered to the outer wall of the right heat insulation cover 5 fixedly connected to the outer wall of the first Velcro 6, a main positioning block 10 that is in contact with the surface of the heat insulation cover body 3 slidably connected to the outer wall of the fixing bracket 2, and a secondary positioning block 14 that is in contact with the surface of the heat insulation cover body 3 detachably connected to the end of the main positioning block 10.

[0031] like Figure 4 As shown, the outer wall of the fixing frame 2 is provided with a nut 8, and the inner wall of the nut 8 is threaded with a bolt 9 that is rotatably connected to the outer wall of the main positioning block 10. This facilitates the effect of driving the main positioning block 10 to slide by setting the bolt 9.

[0032] like Figure 4 As shown, the outer wall of the main positioning block 10 is fixedly connected to a first spring 12 which is fixedly connected to the outer wall of the fixing frame 2. This facilitates the easy resetting of the main positioning block 10 when it is loosened by setting the first spring 12.

[0033] like Figure 4 As shown, a sliding groove 11 is provided at the connection between the outer wall of the fixing frame 2 and the main positioning block 10. There are two sets of main positioning blocks 10. The positions of the two sets of main positioning blocks 10 are symmetrical about the central axis of the heat insulation cover 3, which is conducive to achieving the effect of sliding and limiting the main positioning blocks 10 through the setting of the sliding groove 11.

[0034] like Figure 5 and Figure 6 As shown, the outer wall of the main positioning block 10 is fixedly connected to the connecting box 13, and the outer wall of the secondary positioning block 14 is fixedly connected to the insert rod 15 which is slidably connected to the outer wall of the connecting box 13. This facilitates the pre-installation of the secondary positioning block 14 by setting the insert rod 15.

[0035] like Figure 1 and Figure 5As shown, the insertion rod 15 and the connecting box 13 are staggered about the central axis of the sub-positioning block 14, which is beneficial to achieve the effect of splicing the sub-positioning blocks 14 one by one by setting the insertion rod 15 and the connecting box 13 about the central axis of the sub-positioning block 14.

[0036] like Figure 6 As shown, the inner wall of the connecting box 13 is slidably connected to a locking block 16 that engages with the outer wall of the insert rod 15. The outer wall of the locking block 16 is fixedly connected to a telescopic rod 17 that slidably engages with the outer wall of the connecting box 13. The outer wall of the telescopic rod 17 is sleeved with a second spring 18 that is fixedly connected to the outer wall of the connecting box 13. One end of the second spring 18 is fixedly connected to a pull block 19 that is fixedly connected to one end of the telescopic rod 17. This facilitates the engagement and installation of the sub-positioning block 14 through the locking block 16.

[0037] like Figure 4 As shown, the outer wall contour of the connection between the main positioning block 10 and the heat insulation cover 3 is arc-shaped, and the outer wall contour of the connection between the secondary positioning block 14 and the heat insulation cover 3 is arc-shaped. This is beneficial to achieve the effect of pressing and fixing the surface of the heat insulation cover by setting the outer wall contour of the connection between the main positioning block 10 and the heat insulation cover 3 to be arc-shaped.

[0038] like Figure 6 As shown, the outer wall contour of the initial pressing part of the locking block 16 and the insertion rod 15 is inclined, and the locking connection part of the locking block 16 and the insertion rod 15 is flat. This is conducive to achieving the effect of pressing and installing the insertion rod 15 and the locking block 16 by setting the outer wall contour of the initial pressing part of the locking block 16 and the insertion rod 15 to be inclined.

[0039] like Figure 6 As shown, a slot is provided at the connection point between the outer wall of the connecting box 13 and the insertion rod 15, which facilitates the pre-installation of the sub-positioning block 14 by means of the slot at the connection point between the outer wall of the connecting box 13 and the insertion rod 15.

[0040] Working principle: When using this quick-installation heat shield, firstly, when using the heat shield to assist the exhaust pipe 1 of the car, in order to improve the effect of double installation of the heat shield on the outer wall of the exhaust pipe 1, the left heat shield 4 and the right heat shield 5 are first fitted onto the outer wall of the exhaust pipe 1, and the first Velcro 6 and the second Velcro 7 are glued together. Then, the bolt 9 is rotated and the nut 8 limits the movement, so that the main positioning block 10 slides along the inner wall of the slide groove 11, pressing and fixing the outer wall of the heat shield, thus achieving the effect of double installation and fixing of the heat shield on the outer wall of the exhaust pipe 1.

[0041] Finally, when positioning and installing the heat insulation cover using the main positioning block 10, in order to improve the effect of adjusting and fixing heat insulation covers of different lengths, the insertion rod 15 is inserted into the connecting box 13. Under the action of the initial pressing part of the insertion rod 15 and the clamping block 16 forming an inclined plane, the telescopic rod 17 and the second spring 18 are pressed until the engaging part of the insertion rod 15 and the clamping block 16 is flat. Under the reaction action of the second spring 18 being pressed, the clamping block 16 engages and fixes the insertion rod 15, so that the main positioning block 10 and the auxiliary positioning block 14 can be engaged and spliced ​​for use, achieving the effect of adjusting and fixing heat insulation covers of different lengths.

[0042] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
