Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe heat insulation cover technology, and in particular to a pipe clamp for an automotive exhaust pipe heat insulation cover. Background Technology

[0002] An exhaust pipe heat shield is a protective device used for automobile engine exhaust pipes. Its main function is to improve the thermal efficiency of the exhaust pipe and prevent heat radiation to the surrounding environment and other vehicle components. When installing the heat shield, pipe clamps are required to fix it in place.

[0003] In existing technology, when fixing the heat insulation cover with a pipe clamp, the clamp at one end of the pipe clamp needs to pass through the clamp teeth, and the clamp teeth enter the slots on the clamp. The pipe clamp forms a ring to fix the heat insulation cover. However, during the operation of a car, the heat insulation cover will inevitably vibrate, and the clamp teeth can easily move out of the slots on the clamp, resulting in the pipe clamp becoming loose and the heat insulation cover easily falling off. Utility Model Content

[0004] This utility model proposes a heat insulation cover clamp for automobile exhaust pipes to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat insulation cover clamp for an automotive exhaust pipe, comprising a clamp body, one end of which has a plurality of evenly distributed slots, some of which are triangular in shape; an mounting rod fixedly installed on one side of the clamp body, wherein the mounting rod can fix the clamp body in place; a pad is fixedly connected to the other end of the clamp body with the aid of a bracket; two teeth are fixedly connected to the bottom of the pad, wherein the teeth have a triangular cross-section; an auxiliary device and a rubber pad; the rubber pad is detachably installed inside the clamp body with the aid of the auxiliary device, wherein the width of the rubber pad is adapted to the width of the clamp body; and a fixing device is provided at the pad, wherein the fixing device can limit the pad's position.

[0006] The aforementioned components achieve the following effect: When it is necessary to fix the heat shield of the air pipe, the worker first places the heat shield on the arc surface of the car's air pipe, then places the pipe clamp body on the outside of the heat shield, pulls one end of the pipe clamp body and passes it through the pad, and finally the teeth on the pad enter the slot at one end of the pipe clamp body, thus fixing the heat shield. The rubber pad on the pipe clamp body protects the heat shield, and finally the worker uses the fixing device to limit the pad, preventing the pad on the pipe clamp body from loosening and the pipe clamp body from detaching due to vibration when the car is moving.

[0007] Preferably, one end of the fixing rope is fixedly connected to one side of the pipe clamp body, wherein the fixing rope passes through the top of the pad and the other end of the fixing rope is located on the other side of the pipe clamp body, and one end of the fixing rope is fixedly connected to a plug rod. The fixing device further includes: a plug hole, which is opened on one side of the pipe clamp body, and the size of the plug hole is slightly larger than the size of the plug rod.

[0008] The effect achieved by the above components is as follows: when the teeth on the pad lock one end of the clamp body into the slot, the worker moves the insertion rod, and the pull rope on the insertion rod is above the pad and ties the pad. At this time, the worker inserts the insertion rod into the insertion hole of the clamp body, which achieves the effect of fixing the fixing rope. By fixing the pad with the fixing rope set by the fixing device, the pad is fixed, which achieves the effect of limiting the pad and preventing the pad from shaking when the car is moving, thus preventing the clamp body from loosening.

[0009] Preferably, a plurality of rubber blocks are fixedly connected to the arc surface of the insertion rod, wherein the rubber blocks are provided with a ramp in the direction of the insertion hole, and a limiting groove is provided at the insertion hole corresponding to the rubber block, wherein the size of the limiting groove is adapted to the size of the rubber block.

[0010] The effect achieved by the above components is as follows: when the insertion rod is inserted into the insertion hole of the clamp body, the inner wall of the insertion hole presses the inclined surface of the rubber block on the insertion rod, and the rubber block deforms. When the rubber block enters the limiting groove, the rubber block returns to its original shape and enters the limiting groove under the action of its own restoring elastic force, thereby achieving the effect of limiting the position of the insertion rod and preventing the insertion rod from falling off when the car is moving.

[0011] Preferably, the arc plate is fixedly connected to one end of the insertion rod, wherein the arc surface of the arc plate is away from the insertion rod.

[0012] The effect achieved by the above-mentioned components is that by setting the arc plate, it is convenient for workers to insert the plug rod into the insertion hole of the pipe clamp body, thus bringing convenience to the workers.

[0013] Preferably, the pull ring is fixedly installed on the end of the plug rod near the fixing rope by means of a connecting post.

[0014] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the insertion rod by setting the pull ring, thereby making it easier for the worker to move the insertion rod and bringing convenience to the worker.

[0015] Preferably, the auxiliary device includes two positioning rods, which are fixedly connected inside the pipe clamp body. The rubber pad has a positioning hole corresponding to the positioning rod, wherein the size of the positioning rod is adapted to the size of the positioning hole.

[0016] The aforementioned components achieve the following effect: When installing the rubber pad, the operator first moves the rubber pad inside the pipe clamp body, aligning the positioning hole on the rubber pad with the positioning rod on the pipe clamp body. Then, the operator inserts the positioning rod into the positioning hole of the rubber pad, thus fixing the rubber pad in place. When the rubber pad needs to be replaced due to aging, the operator simply pulls the rubber pad out of the pipe clamp body. This auxiliary device effectively fixes the rubber pad and facilitates replacement when the rubber pad ages, improving the practicality of the pipe clamp body.

[0017] Preferably, the pointed protrusion is fixedly connected to one end of the positioning rod, wherein the tip of the pointed protrusion is away from the positioning rod.

[0018] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the positioning rod into the positioning hole of the rubber pad, thus providing convenience for workers.

[0019] Preferably, several triangular plates are fixedly connected to one side of the rubber pad, and several triangular grooves are respectively formed inside the pipe clamp body, wherein the triangular plates and triangular grooves correspond one-to-one, and the size of the triangular plates matches the size of the triangular grooves. The effect achieved by the above components is that by inserting the triangular plates of the rubber pad into the triangular grooves of the pipe clamp body, the rubber pad is limited, preventing the rubber pad from shaking.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] When the teeth on the pad lock one end of the clamp body into the slot, the worker moves the insertion rod. The pull rope on the insertion rod is above the pad and ties the pad in place. Then, the worker inserts the insertion rod into the insertion hole of the clamp body, which achieves the effect of fixing the rope. By fixing the pad with the rope set by the fixing device, the pad is fixed, which achieves the effect of limiting the pad and preventing the pad from shaking when the car is moving, thus preventing the clamp body from loosening.

Detailed Implementation

[0028] Reference Figure 1-5 As shown, this embodiment discloses a heat insulation cover clamp for an automotive exhaust pipe, including a clamp body 1. One end of the clamp body 1 has several evenly distributed slots 5, some of which are triangular. An installation rod 2 is fixedly installed on one side of the clamp body 1, which can fix the clamp body 1 in place. A pad 3 is fixedly connected to the other end of the clamp body 1 with the aid of a bracket. Two teeth 6 are fixedly connected to the bottom of the pad 3, and the teeth 6 have a triangular cross-section. A rubber pad 4 is detachably installed inside the clamp body 1 with the aid of an auxiliary device 8, and the width of the rubber pad 4 is adapted to the width of the clamp body 1. A fixing device 7 is provided at the pad 3, which can limit the pad 3. When it is necessary to fix the heat shield of the trachea, the staff first puts the heat shield on the arc surface of the car's trachea. Then, the staff puts the clamp body 1 on the outside of the heat shield. The staff pulls one end of the clamp body 1 and passes it through the pad 3. Finally, the teeth 6 on the pad 3 enter the groove 5 at one end of the clamp body 1, thus achieving the effect of fixing the heat shield. The rubber pad 4 on the clamp body 1 protects the heat shield. Finally, the staff uses the fixing device 7 to limit the pad 3 to prevent the pad 3 on the clamp body 1 from loosening and the clamp body 1 from falling off due to vibration when the car is running.

[0029] Reference Figure 1-5As shown, one end of the fixing rope 71 is fixedly connected to one side of the pipe clamp body 1. The fixing rope 71 passes through the top of the pad 3, and the other end of the fixing rope 71 is located on the other side of the pipe clamp body 1. One end of the fixing rope 71 is fixedly connected to the insertion rod 72. The fixing device 7 also includes an insertion hole 73, which is opened on one side of the pipe clamp body 1. The size of the insertion hole 73 is slightly larger than the size of the insertion rod 72. When the jaw 6 on the pad 3 locks the slot 5 at one end of the pipe clamp body 1, the worker moves the insertion rod 72. The pull rope on the insertion rod 72 is located above the pad 3 and ties the pad 3. At this time, the worker inserts the insertion rod 72 into the insertion hole 73 of the pipe clamp body 1, thus achieving the effect of fixing the fixing rope 71. By fixing the pad 3 with the fixing rope 71 set by the fixing device 7, the pad 3 is limited, preventing the pad 3 from shaking when the car is moving, which would cause the pipe clamp body 1 to loosen.

[0030] Reference Figure 1-5 As shown, several rubber blocks 74 are fixedly connected to the arc surface of the insertion rod 72. Each rubber block 74 has a ramp extending towards the insertion hole 73. A limiting groove 75 is provided in the insertion hole 73 corresponding to the rubber block 74, and the size of the limiting groove 75 matches the size of the rubber block 74. When the insertion rod 72 is inserted into the insertion hole 73 of the pipe clamp body 1, the inner wall of the insertion hole 73 presses against the ramp surface of the rubber block 74 on the insertion rod 72, causing the rubber block 74 to deform. When the rubber block 74 enters the limiting groove 75, under the action of its own restoring elasticity, the rubber block 74 returns to its original shape and enters the limiting groove 75, achieving the effect of limiting the position of the insertion rod 72 and preventing it from falling off during vehicle vibration. An arc plate 76 is fixedly connected to one end of the insertion rod 72, with the arc surface of the arc plate 76 away from the insertion rod 72. The arc plate 76 facilitates the insertion of the insertion rod 72 into the insertion hole 73 of the pipe clamp body 1, providing convenience for the worker. The pull ring 77 is fixedly installed on the end of the insertion rod 72 near the fixing rope 71 via a connecting post. The pull ring 77 increases the contact area between the worker's hand and the insertion rod 72, thus facilitating the movement of the insertion rod 72 and providing convenience for the worker.

[0031] Reference Figure 1-5As shown, the auxiliary device 8 includes two positioning rods 81, which are fixedly connected inside the pipe clamp body 1. The rubber pad 4 has positioning holes 82 corresponding to the positioning rods 81, with the dimensions of the positioning rods 81 matching the dimensions of the positioning holes 82. When installing the rubber pad 4, the operator first moves the rubber pad 4 inside the pipe clamp body 1, aligning the positioning holes 82 on the rubber pad 4 with the positioning rods 81 on the pipe clamp body 1. Then, the operator inserts the positioning rods 81 into the positioning holes 82 of the rubber pad 4, thus fixing the rubber pad 4 in place. When the rubber pad 4 needs to be replaced due to aging, the operator simply pulls it out of the pipe clamp body 1. The auxiliary device 8 effectively fixes the rubber pad 4 and facilitates replacement when the rubber pad 4 ages, improving the practicality of the pipe clamp body 1.

[0032] Reference Figure 1-5 As shown, a pointed protrusion 85 is fixedly connected to one end of the positioning rod 81, with the tip of the protrusion 85 being away from the positioning rod 81. The pointed protrusion 85 facilitates the insertion of the positioning rod 81 into the positioning hole 82 of the rubber pad 4, providing convenience for the operator. Several triangular plates 84 are fixedly connected to one side of the rubber pad 4, and several triangular grooves 83 are respectively formed inside the pipe clamp body 1. The triangular plates 84 and triangular grooves 83 correspond one-to-one, and the dimensions of the triangular plates 84 and triangular grooves 83 are matched. By inserting the triangular plates 84 of the rubber pad 4 into the triangular grooves 83 of the pipe clamp body 1, the rubber pad 4 is effectively limited, preventing it from shaking.

[0033] Working principle: When it is necessary to fix the heat shield of the air pipe, the worker first puts the heat shield on the arc surface of the car air pipe. Then, the worker puts the pipe clamp body 1 on the outside of the heat shield. The worker pulls one end of the pipe clamp body 1 and passes it through the pad 3. Finally, the teeth 6 on the pad 3 enter the groove 5 at one end of the pipe clamp body 1, achieving the effect of fixing the heat shield. The rubber pad 4 on the pipe clamp body 1 protects the heat shield. At this time, the worker moves the insertion rod 72 through the pull ring 77. The pull rope on the insertion rod 72 is above the pad 3 and ties the pad 3. The worker then inserts the insertion rod 72 with the help of the arc plate 76. The insertion hole 73 of the pipe clamp body 1 is inserted into the inner wall of the insertion hole 73, which presses the inclined surface of the rubber block 74 on the insertion rod 72. The rubber block 74 deforms. When the rubber block 74 enters the limiting groove 75, the rubber block 74 returns to its original shape and enters the limiting groove 75 under the action of its own restoring elastic force. This achieves the effect of limiting the position of the insertion rod 72 and prevents the insertion rod 72 from falling off when the car is moving. The pad 3 is tied by the fixing rope 71 set by the fixing device 7, which achieves the effect of limiting the pad 3 and prevents the pad 3 from shaking when the car is moving, thus preventing the pipe clamp body 1 from becoming loose.

[0034] When installing the rubber pad 4, the worker first moves the rubber pad 4 into the inside of the pipe clamp body 1, aligning the positioning hole 82 on the rubber pad 4 with the positioning rod 81 on the pipe clamp body 1. Then, the worker inserts the positioning rod 81 into the positioning hole 82 of the rubber pad 4 with the help of the pointed protrusion 85, while the triangular plate 84 of the rubber pad 4 is inserted into the triangular groove 83 of the pipe clamp body 1, thus achieving the effect of limiting the rubber pad 4. When the rubber pad 4 ages and needs to be replaced, the worker simply pulls the rubber pad 4 out of the pipe clamp body 1. The auxiliary device 8 achieves the effect of fixing the rubber pad 4, and at the same time, it is convenient for the worker to replace the rubber pad 4 when it ages, thus improving the practicality of the pipe clamp body 1.
