Technical Field

[0001] This utility model relates to the field of optoelectronic frame technology, specifically an optoelectronic frame for optoelectronic sensors. Background Technology

[0002] Although existing optoelectronic brackets are constantly being innovated and developed, and basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN222544734U discloses a photoelectric frame for a photoelectric sensor, including: a mounting base, a rotating column, a U-shaped block, and a movable block arranged sequentially on the top of the mounting base; with the hinge point on the connecting strip and the hinge block as the center, several semi-circular shells are flipped to the top of the movable block, enclosing the photoelectric sensor body inside the several semi-circular shells, and the top of the photoelectric sensor body is exposed from the top of the several semi-circular shells. The several semi-circular shells are connected by the cooperation of the connectors, which achieves a comprehensive protection effect for the photoelectric sensor body, avoiding exposure to the working area or external environment, and further preventing damage to the photoelectric sensor body in the event of collision or other situations.

[0004] The aforementioned photoelectric bracket uses two semi-circular shells to cover the sensor, improving the protection of the sensor. However, its overall structure is complex and the production cost is high. In addition, there are gaps between the semi-circular shells and the sensor, which makes it easy for rainwater to seep in. Therefore, the actual protection effect is still insufficient. So, a photoelectric bracket for photoelectric sensors is needed to solve the above problems. Utility Model Content

[0011] The above technical solution allows for a large amount of space to be reserved for sensor operation.

[0012] As a further improvement to this utility model, the plastic sleeve is composed of two parts, a tail section and a transparent section, which are connected and limited by threads, and the threaded area is located on the inner surface of the transparent section.

[0013] Implementing the above technical solution facilitates the replacement of the transparent cylinder section.

[0014] As a further improvement to this utility model, a pressure ring frame that abuts against the outer wall of the sensor is connected to the inner surface of the transparent cylindrical section.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example: Referring to the accompanying drawings, this utility model provides a photoelectric sensor bracket for achieving stable installation, angle adjustment, and protection of the photoelectric sensor. Its core structure and usage process are as follows: Supporting institutions 100 Base 110 and bracket 111 The base is made of 110 cast iron and has 4 bolt holes on the surface (compatible with M6 bolts) for fixing to the load-bearing surface (such as equipment frame or workbench). Bracket 111: Made of ABS material, it can be rotatably connected to base 110 via a pivot (for easy adjustment of sensor orientation).

[0033] Plastic sleeve 112 Structural composition: It consists of a tail section 1021 (ABS material integrated with bracket 111) and a transparent section 1022 (PC material, light transmittance ≥90%) connected by threads, with the threaded area located on the inner surface of the transparent section 1022; Protection and Spacing: The Z-axis spacing between the sleeve opening and the base 110 is ≥ 2 times the length of the sensor. The inner surface of the transparent cylindrical section 1022 is connected to the pressure ring 1023 (rubber material, inner diameter is 0.5~1mm smaller than the outer diameter of the sensor) to abut against the outer wall of the sensor to achieve axial positioning.

[0034] Fixed mechanism 200 Mounting base 210 Structural design: It is symmetrically divided into two parts (semi-cylindrical), injection molded from ABS material, and spliced ​​to form a through hole (fitting the outer diameter of the sensor). The inner wall of the through hole is provided with anti-slip texture. The outer surface of the fixing seat 210 is provided with external thread, which meshes with the internal thread of the open inner wall of the plastic sleeve 112.

[0035] Knob area 212: The mounting base 210 extends toward the plastic sleeve 112 to form a hexagonal knob, which is easy to screw in manually.

[0036] Limit and locking components 213: A protruding ring on the inner wall of the plastic sleeve 112, located at the end of the thread rotation stroke, used to limit the screwing depth of the fixing seat 210 (to avoid over-tightening and damaging the sensor). The locking component 211 consists of matching protrusions and recesses, which are located on the mating surfaces of the two parts of the fixing base 210 respectively. After splicing, the protrusions are embedded in the recesses to prevent the two parts of the fixing base 210 from rotating relative to each other.

[0037] Usage process Base fixing and bracket adjustment: Secure the base 110 to the bearing surface with bolts.

[0038] Sensor mounting and mounting bracket assembly: The photoelectric sensor is placed into the through hole of the half-fixed base 210, and the sensor cable is passed out from the cable groove of the fixed base 210 and the knob area 212. Cover the other half of the fixing seat 210, so that the protrusion of the locking component 211 is aligned and fitted with the notch, and the splicing of the fixing seat 210 is completed (at this time the sensor is clamped).

[0039] Screw-in sleeve and positioning: Hold the knob area 212 and screw the fixing seat 210 into the threaded hole of the plastic sleeve 112. Rotate clockwise until the sensor rises along the inner cavity of the sleeve and abuts against the pressure ring 1023 to complete the axial positioning of the sensor.

[0040] Replacement of transparent section: If the transparent section 1022 needs to be replaced (e.g., due to wear or to a different light transmittance model), rotate the transparent section 1022 counterclockwise to disengage it from the threaded engagement with the tail section 1021, remove the old section, and then screw in the new section.
