Description

Technical Field

[0001] This utility model relates to the field of inductive switches, and more particularly to a photoelectric inductive switch. Background Technology

[0002] Photoelectric sensor switches utilize the ability of a rolling steel ball to block a light beam to trigger the switch. Typically, the steel ball is placed inside a housing, with transmitting and receiving components, used for transmitting and receiving signals respectively, mounted on either side of the housing. When the switch is laid flat, the steel ball inside the housing blocks the light-transmitting hole, preventing the receiving component from receiving the signal from the transmitting component. When the switch is tilted, the steel ball no longer blocks the light-transmitting hole, thus triggering the switch.

[0003] In existing photoelectric sensor switches, the housing containing the steel ball is usually fixed in an inner core, and the inner core containing the complete unit is then fixed in the outer casing to achieve assembly. However, in this assembly process, the inner core is a dispensable component that only serves to strengthen the fixation. The presence of the inner core not only wastes resources and increases costs, but also further complicates the assembly and installation process. Utility Model Content

[0009] Preferably, the receiving component has a second protrusion on its side wall, and the second protrusion and the second light-transmitting through hole cooperate to block each other.

[0010] Preferably, the ball compartment support and the ball compartment cover support are formed by injection molding.

[0011] Preferably, the inner wall of the ball groove is funnel-shaped, expanding from the inside out, and the inner wall of the ball groove is provided with several ribs to prevent the steel ball from sticking and not rolling. The ribs are arranged circumferentially around the central axis of the ball chamber support.

[0012] Preferably, the ball compartment cover bracket has a protruding ring on the side near the ball compartment bracket that engages with the outer edge of the ball groove.

[0013] Preferably, the switching unit includes a ball chamber bracket and a ball chamber cover bracket that covers the ball chamber bracket, with the ball chamber bracket and the ball chamber cover bracket arranged vertically.

Example 1

[0025] like Figures 1 to 3 As shown, this utility model provides a photoelectric sensor switch, including a housing 1 and a switch unit integrated within the housing 1; specifically, the switch unit includes a ball chamber bracket 2 and a ball chamber cover bracket 3 covering the side of the ball chamber bracket 2, the ball chamber bracket 2 and the ball chamber cover bracket 3 are arranged side by side; a transmitting element 4 is installed inside the ball chamber bracket 2, and a receiving element 5 is installed inside the ball chamber cover bracket 3; a ball groove 6 is provided inside the ball chamber bracket 2, and a steel ball 7 is rolled inside the ball groove 6.

[0026] The ball chamber support 2 has a first mounting cavity 8 on its side, and the transmitting component 4 is installed and fixed in the first mounting cavity 8; specifically, the inner wall of the first mounting cavity 8 has a first light-transmitting hole 9, which is connected to the ball groove 6.

[0027] The side wall of the transmitting element 4 has a first protrusion 10, which cooperates with the first light-transmitting hole 9 to block it.

[0028] The ball compartment cover bracket 3 has a second mounting cavity 11 on its side. The receiving component 5 is installed and fixed in the second mounting cavity 11. The inner wall of the second mounting cavity 11 has a second light-transmitting hole 12. The second light-transmitting hole 12 passes through the ball compartment cover bracket 3 and communicates with the ball groove 6. Specifically, when the steel ball 7 is blocked between the first light-transmitting hole 9 and the second light-transmitting hole 12, the receiving component 5 does not receive the signal emitted by the transmitting component 4.

[0029] The receiving component 5 has a second protrusion 13 on its side wall, and the second protrusion 13 and the second light-transmitting hole 12 cooperate to block each other.

[0030] The ball compartment support 2 and the ball compartment cover support 3 are formed by injection molding.

[0031] The inner wall of the ball groove 6 is funnel-shaped, expanding from the inside out. The inner wall of the ball groove 6 is provided with several ribs 14 to prevent the steel ball 7 from sticking and not rolling. Specifically, the ribs 14 are arranged circumferentially around the central axis of the ball chamber support 2.

[0032] The ball compartment cover bracket 3 has a protruding retaining ring 15 on the side near the ball compartment bracket 2, which engages with the outer edge of the ball groove 6.

[0033] The electrical inductive connection between the transmitting element 4 and the receiving element 5 and the principle of their operation are commonly used and easily understood by those skilled in the art, and therefore will not be elaborated upon further.

[0034] The assembly principle of this utility model is as follows: The transmitting element 4 is installed and fixed in the first mounting cavity 8, so that the first protrusion 10 on the transmitting element 4 abuts and cooperates with the first light-transmitting hole 9 in the first mounting cavity 8 to block it; the receiving element 5 is installed and fixed in the second mounting cavity 11, so that the second protrusion 13 on the receiving element 5 abuts and cooperates with the second light-transmitting hole 12 in the second mounting cavity 11 to block it; then the steel ball 7 is placed into the ball groove 6 in the ball compartment bracket 2, so that the steel ball 7 rolls freely in the ball groove 6, and the retaining ring 15 protruding on the inner wall of the ball compartment cover bracket 3 and the outer edge of the ball groove 6 cooperate to engage, so that the ball compartment cover bracket 3 and the ball compartment bracket 2 are engaged and fixed; finally, the outer shell 1 is placed on the outside of the ball compartment bracket 2 and the ball compartment cover bracket 3 for final fixation.

[0035] The working principle of this utility model is as follows: When the photoelectric sensor switch is laid flat, the steel ball 7 blocks the first light-transmitting hole 9 and the second light-transmitting hole 12, so that the transmitting element 4 and the receiving element 5 cannot send light transmission signals through the first light-transmitting hole 9 and the second light-transmitting hole 12. Therefore, the receiving element 5 cannot receive the light signal emitted by the transmitting element 4.

[0036] When the photoelectric sensor switch is tilted to a certain angle, the steel ball 7 rolls freely in the ball groove 6. When the steel ball 7 rolls until it no longer blocks the space between the first light-transmitting hole 9 and the second light-transmitting hole 12, the light signal emitted by the transmitting element 4 can be received by the receiving element 5, thereby realizing the induction trigger.

[0037] The advantages of this utility model are: by eliminating the inner core structure in the existing photoelectric sensor switch, the housing containing the steel ball 7 can be directly installed inside the outer shell 1, saving resources, reducing costs, and improving the assembly and installation efficiency of the whole machine.

The ball chamber bracket 2 and the ball chamber cover bracket 3 are arranged vertically. By changing the assembly position of the ball chamber bracket 2 and the ball chamber cover bracket 3, a different assembly method than that in Embodiment 1 is achieved, but the assembly principle, composition structure, and working principle are the same as in Embodiment 1. Other structures are the same as in Embodiment 1.
