Photoelectric detection method has the advantages of high precision, fast response, non-contact, etc., and can measure many parameters. The structure of the sensor is simple and the form is flexible and diverse. Therefore, photoelectric sensor is widely used in detection and control. Photoelectric sensor can be divided into slot type photoelectric sensor, through-beam photoelectric sensor, reflector type photoelectric switch and diffuse reflection type photoelectric switch.

[0003] The light emitted by the projector is generally in a straight line. No matter which type, the light receiver can only work normally when it can receive the light emitted by the projector. This has certain requirements for the installation of photoelectric sensors. If the installation angle is not appropriate and the light receiver cannot receive the light emitted by the projector, the photoelectric sensor will not work properly.

[0004] The installation of the projector and the light receiver must take into account the coordination with the structure of the industrial equipment. Generally, a bracket is provided to facilitate the installation of the projector and the light receiver. Photoelectric sensor manufacturers generally provide a simple L-shaped bracket for use with photoelectric sensors. However, in actual use, due to the diversity of industrial equipment structures, it is often encountered that the installation angle of the projector and the light receiver cannot be used normally after the L-shaped bracket provided by the manufacturer is connected to the industrial equipment. It is necessary to process a bracket of a special shape before use. It is also often encountered that the photoelectric sensors at different positions on the same industrial equipment require different bracket structures, and it is necessary to design and process brackets of various shapes to meet the use.

[0024] like Figure 1-Figure 7As shown, the utility model is a photoelectric sensor angle adjustment bracket including a mounting seat 1, a support plate 2, an adjustment bolt 5 and a spring 6. The mounting seat 1 includes a top plate 101 and a vertical plate 102. Two vertical plates 102 are provided. One top plate 101 and two vertical plates 102 form an n shape. The mounting seat 1 includes two bottom plates 103. The bottom plates 103 are respectively fixedly connected to one end of the two vertical plates 102 away from the top plate 101. Two through holes Ⅰ106 are provided on each bottom plate 103. The through holes Ⅰ106 are connected with fixing bolts 4. Screw holes connected with the fixing bolts 4 are provided on the industrial equipment. The fixing bolts 4 pass through the through holes Ⅰ106 and are connected to the screw holes on the industrial equipment. A mounting hole Ⅰ105 is provided in the center of the top plate 101. Three screw holes 104 are provided on the top plate 101. The three screw holes 104 are all provided with Outside the mounting hole Ⅰ105, three screw holes 104 form a triangle, a mounting hole Ⅱ202 is provided in the center of the support plate 2, three through holes Ⅱ201 are provided on the support plate 2, the three through holes Ⅱ201 are all provided outside the mounting hole Ⅱ202, and the three through holes Ⅱ201 form a triangle, the support plate 2 is provided above the top plate 101, the three through holes Ⅱ201 correspond to the three screw holes 104 one by one, and the three through holes Ⅱ201 are all connected with adjusting bolts 5, and the front end of each adjusting bolt 5 passes through the through hole Ⅱ201 and is connected to the screw hole 104, and each adjusting bolt 5 is sleeved with a spring 6, and the two ends of the spring 6 are respectively connected to the top surface of the top plate 101 and the bottom surface of the support plate 2, the photoelectric sensor 3 passes through the mounting hole Ⅱ202 and the mounting hole Ⅰ105, and the support plate 2 is clamped between the two mounting nuts of the photoelectric sensor 3.

[0025] When the utility model is in use, the mounting base 1 is fixedly connected to the industrial equipment through the fixing bolt 4 in the through hole Ⅰ106, and then the wire at the tail of the photoelectric sensor 3 is passed through the mounting hole Ⅱ202 and the mounting hole Ⅰ105, and then the two mounting nuts of the photoelectric sensor 3 are connected to the support plate 2. After the photoelectric sensor 3 and the support plate 2 are connected in place, the adjusting bolt 5 and the spring 6 are installed. After the installation is in place, the angle of the support plate 2 can be adjusted by rotating any adjusting bolt 5. The change of the angle of the support plate 2 drives the change of the angle of the photoelectric sensor 3, so that the angle adjustment of the photoelectric sensor 3 is realized. The photoelectric sensor 3 can be finally adjusted to a suitable angle through the adjustment and cooperation of the three adjusting bolts 5.

[0026] It should be noted that, since the function of the spring 6 is to lift the support plate 2 and keep it stable, the selection of the spring 6 should take into account that the spring 6 has a certain amount of compression in the initial position before adjustment, so as to ensure that the support plate 2 is always lifted by the spring 6 during adjustment. In addition, since the relative position of the adjusting bolt 5 and the through hole II 201 is inclined when the angle of the support plate 2 changes, the inner diameter of the through hole II 201 should be larger than the outer diameter of the adjusting bolt 5 than the conventional setting, so as to ensure that the adjusting bolt 5 and the through hole II 201 are not stuck within a reasonable angle adjustment range.

[0027] According to different structures of industrial equipment, the connection method between the base plate 103 and the through hole Ⅰ106 and the industrial equipment may be other than the connection using the fixing bolts 4 as described in this embodiment, and other connection methods such as welding may also be used. It is even possible that the mounting base 1 does not have a base plate 103 but directly welds the industrial equipment to the vertical plate 102. However, through practice, since the angles of the support plate 2 and the photoelectric sensor 3 in the utility model are adjustable, the method of connecting the base plate 103 and the industrial equipment through the fixing bolts 4 in the through hole Ⅰ106 as described in this embodiment can meet most usage scenarios.

[0028] The mounting hole I 105 and the mounting hole II 202 are both trapezoidal. Two of the three screw holes 104 are arranged outside the longer bottom edge of the trapezoidal mounting hole I 105, and another of the three screw holes 104 is arranged outside the shorter bottom edge of the trapezoidal mounting hole I 105. Two of the three through holes II 201 are arranged outside the longer bottom edge of the trapezoidal mounting hole II 202, and another of the three through holes II 201 is arranged outside the shorter bottom edge of the trapezoidal mounting hole II 202.

[0029] Furthermore, the mounting hole I 105 and the mounting hole II 202 are both isosceles trapezoids, the triangle formed by the three screw holes 104 is an isosceles triangle, and the triangle formed by the three through holes II 201 is an isosceles triangle. The line connection of the two base centers of the mounting hole I 105 of the isosceles trapezoid coincides with the center line of the triangle formed by the three screw holes 104. The line connection of the two base centers of the mounting hole II 202 of the isosceles trapezoid coincides with the center line of the triangle formed by the three through holes II 201.

[0030] This embodiment is described by using a photoelectric sensor 3 that is cylindrical and provided with external threads and is installed using two mounting nuts. The isosceles trapezoidal mounting holes I105 and mounting holes II202 are provided in directions suitable for photoelectric sensors 3 of different outer diameters. The mounting holes II202 are mainly used to connect the photoelectric sensor 3, while the mounting holes I105 are used to provide mounting space for the rear of the photoelectric sensor 3. The triangle formed by the three screw holes 104 and the triangle formed by the three through holes II201 are both isosceles triangles, so that the deflection of the support plate 2 is more flexible when the three adjustment bolts 5 are rotated, and the structure is always stable.

[0031] In addition to the isosceles trapezoidal mounting holes I105 and II202 described in the present embodiment, which are suitable for photoelectric sensors 3 of different outer diameters, mounting holes I105 and II202 of different shapes may also be provided according to the connection methods of other photoelectric sensors 3. For example, for a square photoelectric sensor 3 having a connecting hole on the side, mounting hole II202 may be provided as a waist-shaped hole for matching. For some photoelectric sensors 3 that do not need to consider the rear holding space, mounting hole I105 may not be provided, or mounting hole I105 may be provided as a conventional circular through hole for the passage of the rear wire of the photoelectric sensor 3.

[0032] The utility model has simple and convenient connection, reasonable structural arrangement, is easy to connect the photoelectric sensor 3, is convenient to adjust the angle of the photoelectric sensor 3, has stable connection of the photoelectric sensor 3, and can be used for photoelectric sensors 3 of different types and sizes, and has promotion value.
