DETAILED DESCRIPTION

[0021] The present application will now be described in further detail with reference to the drawings. The drawings are simplified schematic illustrations of the basic structure of the present application and therefore only show the components relevant to the present application.

[0022] As shown in the drawings, a fixing device for a sensor with a protective structure comprises clamps arranged on both sides of the sensor 8 along the axial direction of the pipe 1, and the clamps are clamped to the pipe 1; the clamps are rotatably provided with protective plates 6, and the protective plates 6 are elastically provided with pressing plates 67 on the side of the protective plates 6 facing the sensor 8. Figures 1-5 The clamps can be fixed to the pipe 1 by bolts, and the distance between the clamps can be adjusted according to the size of the sensor 8.

[0023] When the two clamps are fixed, the protective plates 6 on the clamps can just cover the sensor 8, thereby protecting the sensor 8 from accidental damage caused by bumps; in addition, the protective plates 6 are also elastically provided with pressing plates 67, which can be adaptively clamped to the sensor 8 to form auxiliary fixation of the sensor 8 and ensure stable operation of the sensor 8.

[0024] In some further embodiments, the clamps comprise first connecting plates and second connecting plates, and the first connecting plates are provided with first connecting holes 30 at both ends, and the second connecting plates are provided with second connecting holes 50 at both ends.

[0025] When the clamps are connected, bolts can be correspondingly inserted through the first connecting holes 30 and the second connecting holes 50, and corresponding nuts can be screwed, thereby fixing the clamps.

[0026]

[0027] ​In some further embodiments, the first connecting plate comprises two first and second clamping plates 2, 3 hingedly arranged with each other; the second connecting plate comprises two third and fourth clamping plates 4, 5 hingedly arranged with each other; the first connecting hole 30 is provided with a first spring 31 on the side facing away from the second connecting plate, the first spring 31 is provided with a first washer 32 at the end away from the first connecting plate, and the first washer 32 is provided with a first mounting hole 33; the second connecting hole 50 is provided with a second spring 51 on the side facing away from the first connecting plate, the second spring 51 is provided with a second washer 52 at the end away from the second connecting plate, and the second washer 52 is provided with a second mounting hole 53.

[0028] Since the pipe 1 has different diameters, in order to maximize the installation of the clamp on the pipe 1, the first connecting plate is arranged as two first and second clamping plates 2, 3 hingedly arranged with each other, if the pipe 1 is thicker, the clamping angle between the first and second clamping plates 2, 3 is larger, if the pipe 1 is thinner, the clamping angle between the first and second clamping plates 2, 3 is smaller, in order to make the clamping more firm, in other embodiments, an elastic pad can be bonded on the side wall of the first and second clamping plates 2, 3 in contact with the pipe 1, so as to ensure the stability of the fixing between the clamp and the pipe 1 under different sizes.

[0029] The first connecting hole 30 is located at the end away from the hinge of the first clamping plate 2 and the end away from the hinge of the second clamping plate 3, respectively, and the second connecting hole 50 is located at the end away from the hinge of the third clamping plate 4 and the end away from the hinge of the fourth clamping plate 5, respectively.

[0030] Since the pipe 1 has different diameters, naturally, the first connecting hole 30 on the first connecting plate and the second connecting hole 50 on the second connecting plate will not be located in two mutually parallel planes, for this purpose, the first spring 31, the first washer 32, the second spring 51 and the second washer 52 are arranged, and at the same time, the first mounting hole 33 is arranged on the first washer 32, and the second mounting hole 53 is arranged on the second washer 52, when the bolt is installed, the bolt passes through the first mounting hole 33, the first spring 31, the first connecting hole 30, the second connecting hole 50, the second spring 51 and the second mounting hole 53 in turn, under the action of the first spring 31 and the second spring 51, the two planes where the first washer 32 and the second washer 52 are located are parallel to each other, thereby ensuring the fixing effect of the bolt.

[0031] In actual situations, the diameter of the bolt is smaller than the diameter of the first connecting hole 30 and the second connecting hole 50, so as to ensure that when the planes where the first connecting hole 30 and the second connecting hole are located are not parallel to each other, the bolt can also pass through normally.

[0032] It should be noted that the structure is not suitable for all specifications of the pipe 1, and can only be reasonably implemented within a certain range. When the specification is too large or too small, the first connecting plate and the second connecting plate of the corresponding specification can be set.

[0033] The hinge between the first clamping plate 2 and the second clamping plate 3, the third clamping plate 4 and the fourth clamping plate 5 can be realized by a pin shaft 40 in a conventional technology.

[0034] In some further embodiments, the rotating shaft 7 is provided on the clamp, and the rotating sleeve 60 is provided on the protective plate 6, and the rotating sleeve 60 is sleeved on the rotating shaft 7.

[0035] Before installation, the protective plate 6 can be relatively rotated relative to the corresponding clamp to facilitate installation.

[0036] In other embodiments, the rotating shaft 7 can be provided on the pin shaft 40.

[0037] In some further embodiments, the protective plate 6 is an arc-shaped plate to form a structure covering the sensor 8.

[0038] In some further embodiments, the protective plate 6 is provided with a sliding sleeve 61, the sliding rod 62 is slidably provided through the protective plate 6 on the sliding sleeve 61, the pressing plate 67 is provided on one end of the sliding rod 62 facing the sensor 8, the third spring 66 is provided on the sliding rod 62, one end of the third spring 66 abuts against one end face of the sliding sleeve 61 facing the sensor 8, and the other end of the third spring 66 abuts against one side of the pressing plate 67 away from the sensor 8.

[0039] Under the action of the third spring 66, the pressing plate 67 can be adaptively pressed and fixed to the sensor 8 to ensure stability during use.

[0040] Specifically, the degree of arc of the protective plate 6 can be two semicircular arc-shaped plates, so that after both protective plates 6 are installed, they are abutted against each other and limited relative to the respective rotating shaft 7 to ensure the stability of auxiliary fixing of the sensor 8.

[0041] The pressing plate 67 can be a kind of plate material with elasticity, such as a rubber plate.

[0042] In some further embodiments, the end of the sliding rod 62 away from the pressing plate 67 is provided with an adjusting handle 63, the adjusting handle 63 is provided with an adjusting hole, one side of the sliding sleeve 61 away from the pressing plate 67 is provided with a stud 64, the stud 64 is provided through the adjusting hole, and the stud 64 is provided with a knob 65 on the section of the stud 64 passing through the adjusting hole.

[0043] The knob 65 is mainly used to prevent the sliding rod 62 and the pressing plate 67 from slipping out of the sliding sleeve 61 under the action of the third spring 66.

[0044] In other embodiments, the arcuate plates are provided with reinforcing bars 300 on the side facing the sensor 8 to increase the crash resistance of the shield 6.

[0045] Obviously, the above-described embodiments are only examples and are not intended to limit the embodiments. Based on the above description, one of ordinary skill in the art can make other different forms of changes or modifications. It is not necessary or possible to exhaust all the embodiments. The obvious changes or modifications derived therefrom are still within the scope of protection of the present application.
