[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, reference Figures 1 to 4 , is the first embodiment of the utility model, which provides an adjustment mechanism to solve the problem that the speed detection device cannot be adjusted after installation, affecting the detection accuracy. It includes a main body component 100, including a containing component 102, a rotating component 103 arranged in the containing component 102, a conflicting component 104 arranged in the rotating component 103, and a connecting component 105 connected to the conflicting component 104; first, the detection machine is connected to the containing component 102 through the rotating component 103, and then the containing component 102 is fixed at a specified position, which can facilitate the subsequent disassembly. In addition, the detection machine is rotated with the containing component 102 as the center, so that the purpose of horizontally adjusting the angle of the detection machine can be achieved. In this process, the rotating component 103 and the conflicting component 104 are connected. The accommodating component 102 can restrict each other in the absence of external force, so that the detection machine will not rotate in the absence of external force, thereby affecting the accuracy of the detection data. The adjusting component 200 includes a control component 201 arranged in the connecting component 105, and a limiting component 202 arranged in the control component 201, and then the control component 201 is pushed to slide in the connecting component 105 to achieve the effect of resisting the limiting component 202, so that the purpose of longitudinally adjusting the angle between the detection machine and the accommodating component 102 can be achieved. Since the control component 201 and the limiting component 202 have a self-locking function, the detection machine will not rotate in the absence of external force, thereby affecting the accuracy of the detection data.

[0037] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, the connecting component 105 includes a support 105a arranged at the end of the connecting rod 104c, and a notch 105b opened outside the support 105a. A pair of supports 105a are fixedly connected to the bottom of the detection machine, so that the accommodating component 102 can be connected to the detection machine through the supports 105a. In this way, after the detection machine is installed, the purpose of adjusting the angle between the detection machine and the conveyor can be achieved. A notch 105b is opened on the lower side of the plate body of one side support 105a.

[0038] Furthermore, the accommodating component 102 includes a shell 102a, a limiting groove 102b opened outside the shell 102a, and a limiting groove 102c opened in the shell 102a and located in the limiting groove 102b; a shell 102a is arranged between a pair of bases, the shell 102a is cylindrical, and its bottom is hollow and connected to the outside, so that an installation structure can be placed inside the shell 102a to facilitate the installation of the shell 102a to a specified position, a limiting groove 102b is opened on the upper side of the rod body of the shell 102a, and limiting grooves 102c are opened at both ends of the shell 102a located inside the limiting groove 102b, and the limiting groove 102c is arranged in a wave shape, so that when the interference component 104 moves to the recessed part in the limiting groove 102c, it will restrain the shell 102a, so that the shell 102a and the support 105a will not rotate in the absence of external force, so the detection accuracy of the detection machine will be improved during operation.

[0039] Furthermore, the rotating assembly 103 includes a rotating ring 103a disposed in the limiting groove 102b, an output rod 103b disposed outside the rotating ring 103a, and a slide groove 103c opened outside the output rod 103b, the abutting assembly 104 includes a limiting block 104a disposed in the slide groove 103c, a force storage spring 104b disposed between the limiting block 104a and the slide groove 103c, and a connecting rod 104c disposed at the end of the output rod 103b, the housing 102a is located in the limiting groove 102b and is rotatably connected to the rotating ring 103a, and the rotating ring 103c is provided outside the output rod 103b. An output rod 103b is fixedly connected to the position of the support 105a at the outer side of 03a, and a pair of output rods 103b are fixedly connected to the separated ends of each other with a connecting rod 104c. The end of the connecting rod 104c on one side is rotatably connected to the support 105a, and the connecting rod 104c on the other side extends into the notch 105b, so that the support 105a and the shell 102a assembly can be rotatably connected, and then the detection device 101 and the shell 102a assembly are also the rotating assembly 103, thereby achieving the purpose of adjusting the detection machine angle;

[0040] Slide grooves 103c are provided above and below the rod body of the output rod 103b, and the slide grooves 103c are used to place the resistance component 104. The inner part of the slide groove 103c is slidably connected with a limiting block 104a, and the limiting block 104a matches the limiting groove 102c. A storage spring 104b is provided between the limiting block 104a and the slide groove 103c. The setting of the storage spring 104b makes it possible for the support 105a to drive the connecting rod 104c, the output rod 103b and the rotating ring 103a to rotate in the limiting groove 102b when the detection device 101 is rotated. At this time, the output rod 103b will drive the limiting block 104a to move in the limiting groove 102c. When the limiting block 104a moves toward the protruding part of the limiting groove 102c, the limiting block 104a will be It will resist and move into the slide groove 103c, and at the same time, it will squeeze the force storage spring 104b, at this time the force storage spring 104b will store force, and when the limiting block 104a moves from the protruding part of the limiting groove 102c to the groove part, the force storage spring 104b will apply the accumulated push on the limiting block 104a, and at this time the limiting block 104a will be pushed into the groove part of the limiting groove 102c by the force storage spring 104b. Therefore, the limiting block 104a can be controlled by the force storage spring 104b to always resist against the limiting groove 102c, so that the purpose of self-locking between the detection shell 102a, the support 105a and the detection can be achieved, so that the detection machine will not rotate in the absence of external force, thereby affecting the accuracy of the detection data.

[0041] Furthermore, the control assembly 201 includes a ratchet 201a connected to the connecting rod 104c, a load ring 201b arranged in the slot 105b, a functional slot 201c opened outside the load ring 201b, and an arc-shaped push plate 201d arranged at the end of the load ring 201b, and the limiting assembly 202 includes a support rod 202a arranged in the functional slot 201c, a push rod 202b arranged outside the support rod 202a, and a coil spring 202c sleeved outside the support rod 202a. The support 105a is located in the slot 105b and is slidably connected to the load ring 201b. The side of the carrying ring 201b is fixedly connected with an arc-shaped push plate 201d, and the surface of the arc-shaped push plate 201d is provided with a through grip, so that the operator can easily push the carrying ring 201b to slide in the slot 105b. The inner wall of the carrying ring 201b is provided with a pair of functional grooves 201c, and the pair of functional grooves 201c are diagonally arranged. The outer side of the rod body of the connecting rod 104c located in the slot 105b is fixedly connected with a pair of ratchets 201a, and the protrusions on the outer sides of the pair of ratchets 201a are arranged in opposite shapes, and the pair of ratchets 201a are arranged in opposite shapes. 1a, there is an adjustment interval between the pair of ratchets 201a, one ratchet 201a corresponds to a functional slot 201c, and another functional slot 201c is opened at the position of the adjustment interval between the pair of ratchets 201a. The adjustment interval can only accommodate one functional slot 201c corresponding to it. The pair of functional slots 201c are both rotatably connected with support rods 202a, and the support rods 202a in the pair of functional slots 201c are both arranged upward, and the outer sides of the pair of support rods 202a are fixedly connected with push rods 202b, and the push rods 202b are located in the functional slots 201c. A coil spring 202c is sleeved, and the coil spring 202c is set so that a pair of push rods 202b are tilted upward and contact the protrusion on the outer side of the ratchet 201a, so that the pair of ratchet wheels 201a can only move in the direction of the tilted end of the push rod 202b to achieve the longitudinal rotation between the shell 102a and the support 105a. Therefore, after the shell 102a is installed, by adjusting the angle between the shell 102a and the support 105a, the problem of adjusting the angle of the detection machine after installation is achieved, and its detection accuracy is improved to a certain extent;

[0042] When the angle between the detection machine and the conveyor to be detected needs to be adjusted in the first direction, by rotating the detection machine in the first direction, the support 105a will drive the carrying ring 201b and the limiting component 202 to rotate. During the rotation, the support rod 202b corresponding to the ratchet 201a will not interfere with the ratchet 201a. Since the protrusions on the outer side of the ratchet 201a are arranged in opposite shapes, and the detection device 101, the support 105a and the shell 102a components are arranged in an inclined shape, in order to prevent the detection device 101 from continuing to rotate in the first direction under its own gravity, By controlling the arc-shaped push plate 201d, the push rod 202b corresponding to the ratchet 201a is driven to move to the adjustment interval position between the pair of ratchet wheels 201a. At this time, the other push rod 202b will conflict with the other ratchet wheel 201a, thereby preventing the detection device 101 from continuing to rotate in the first direction under its own gravity, thereby affecting the accuracy of the detection data of the detection device 101. Similarly, the rotation in the second direction has the same principle as the rotation in the first direction, thereby realizing the problem of the adjustable angle of the detection machine after installation and improving its detection accuracy to a certain extent.

[0043] The rest of the structure is the same as that of Example 1.

A speed sensor sensing surface must be welded on the side of the driven wheel or the rotating shaft (the sensing surface must be made of iron material);

[0047] The sensing surface provides a pulse signal to the intelligent speed sensor. When the driven wheel rotates one circle, the sensing surface passes through the intelligent speed sensor detection area once, thereby generating a pulse signal.

[0048] When the intelligent speed sensor detects a pulse signal, the pulse indicator light on the intelligent speed sensor panel flashes;

[0049] In addition, the detection device 101 can detect the rotation speed within a certain range, and the specific detection range, lower limit value, upper limit value, and alarm value can be manually set according to the needs of the site;

The trigger component 301 abuts against the position to be installed, so that the trigger component 301 moves toward the inside of the accommodating component 102. During the movement, the clamping component 302 will abut against the closing of the clamping component 302 and clamp the position to be installed. At this time, locking can be achieved through the locking component 303, thereby achieving the purpose of facilitating the installation of the detection device 101.

The resistance plate 301b is slidably connected in the movable groove 102d, and the resistance plate 301b and the rotating rod 302a are mutually offset. In this way, when the resistance rod 301a drives the resistance plate 301b to rise and resist the side of the action groove 102e, it will not interfere with the rotating rod 302a.

[0053] First, the resistance rod 301a is made to resist the position to be installed, and then the device is pressed downward. At this time, the resistance rod 301a will drive the resistance plate 301b and the slide plate 301c to slide in the movable groove 102d and the action groove 102e respectively. The slide plate 301c will squeeze the return spring 301d during the movement, and the resistance plate 301b will resist the action rod 302b during the sliding process. The action rod 302b will rotate from the inclined state to the vertical direction with the rotating rod 302a as the center under the resistance of the resistance plate 301b. At the same time, the coil spring 302d in the rotating groove 102f will be wound, and the action rod 302b will drive the arc clamping plate 302c to clamp the position to be installed during the rotation process, thereby achieving the purpose of installing the shell 102a component.
