[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-5 This utility model embodiment provides an integrated small photoelectric switch, which includes: a photoelectric switch body 1 and a fixed shell 2. A push-off component 6 is provided on the back of the fixed shell 2, a clamping and fixing component 4 is provided on the fixed shell 2, a through groove 3 is provided at the bottom of the fixed shell 2, and a tail wire protection component 5 is provided at the bottom of the fixed shell 2.

[0028] In the integrated miniature photoelectric switch of this utility model, the clamping and fixing component 4 ensures that the components will not shift within the fixing shell 2 through double fixing in both vertical and horizontal directions, thus guaranteeing the stability of the photoelectric switch during operation and preventing the detection accuracy and normal operation of the photoelectric switch from being affected by loose components. The push-off component 6 simplifies the disassembly process of the components and improves the convenience of operation. When it is necessary to maintain the photoelectric switch or replace components, the internal components can be quickly and easily removed. The tail wire protection component 5 ensures the stability of the signal transmission of the photoelectric switch. The fixing shell 2, as the carrier of the entire photoelectric switch, provides the installation foundation and support structure for the photoelectric switch body 1, as well as the clamping and fixing component 4, the push-off component 6, the tail wire protection component 5, etc.

[0029] The clamping and fixing assembly 4 includes an upper pressure plate 41 and a side pressure plate 47. A vertical rod 42 is fixedly installed at the bottom of the upper pressure plate 41, and a tension spring 43 is fixedly installed at the bottom end of the vertical rod 42. A vertical rod mounting groove 44 is opened at the top of the fixing shell 2. The tension spring 43 is fixedly installed inside the vertical rod mounting groove 44. The inner wall of the vertical rod mounting groove 44 is slidably connected to the vertical rod 42. A first compression spring 46 is fixedly installed on the outer wall of the side pressure plate 47. Clamping plate mounting grooves 45 are opened on the inner walls of both sides of the fixing shell 2. The other end of the first compression spring 46 is fixedly installed on the inner wall of the clamping plate mounting groove 45.

[0030] In the integrated miniature photoelectric switch of this utility model, when the photoelectric switch needs to be fixed, the upper pressure plate 41 is moved upward by an external force. Since the vertical rod 42 is slidably connected to the inner wall of the vertical rod mounting groove 44, the upper pressure plate 41 drives the vertical rod 42 to slide upward in the vertical rod mounting groove 44. During this process, the tension spring 43 is stretched. The tension spring 43 has a tendency to return to its original shape and will generate an upward pulling force. This pulling force allows the upper pressure plate 41 to automatically reset after losing the external force. At the same time, it can also apply a downward pressure to the object placed below it, playing a fixing role. As for the side pressure plate 47, when there is When an object is placed inside the fixed housing 2 and needs to be fixed, the object presses against the side pressure plate 47. Under the pressure of the object, the side pressure plate 47 moves into the clamping plate mounting groove 45, causing the first compression spring 46 to be compressed. After the first compression spring 46 is compressed, it will generate a reverse elastic force. This elastic force pushes the side pressure plate 47 to press towards the object, thereby clamping and fixing the object in the horizontal direction. Through the synergistic action of the upper pressure plate 41 and the side pressure plate 47, the object is fixed from the vertical and horizontal directions respectively, which can stably fix the object inside the fixed housing 2 and realize the clamping and fixing function of the photoelectric switch.

[0031] The push-off assembly 6 includes a push plate 61, a connecting rod 63 fixedly installed on the outer wall of the push plate 61, the other end of the connecting rod 63 fixedly installed on the press plate 65, a third compression spring 64 fitted on the outer wall of the connecting rod 63, a groove 62 is provided on the inner wall of the back of the fixing shell 2, the connecting rod 63 passes through the through hole provided on the inner wall of the groove 62, one end of the third compression spring 64 is fixedly installed on the outer wall of the back of the fixing shell 2, and the other end of the third compression spring 64 is fixedly installed on the outer wall of the press plate 65.

[0032] In the integrated miniature photoelectric switch of this utility model, when it is necessary to push out an object fixed inside the fixed housing 2, an external force presses the button plate 65. After the button plate 65 is subjected to force, it drives the connecting rod 63 fixedly connected to it, causing the connecting rod 63 to move into the fixed housing 2 along the through hole on the inner wall of the groove 62. During this process, the third compression spring 64, which is fitted on the outer wall of the connecting rod 63, is compressed. One end of the third compression spring 64 is fixed to the outer wall of the back of the fixed housing 2, and the other end is connected to the button plate 65. When compressed, it generates a reverse elastic force. As the connecting rod 63 moves, the push plate 61, which is fixed to the other end of the connecting rod 63, also moves in the same direction. The push plate 61 pushes the object inside the fixed shell 2 into the interior of the fixed shell 2. After the object is pushed out, the external force acting on the push plate 65 is removed. Due to the characteristic of the third compression spring 64 to return to its original shape, the elastic potential energy stored in it is converted into kinetic energy. The resulting elastic force pushes the push plate 65 outward. The push plate 65 drives the push plate 61 to reset through the connecting rod 63, so that the push plate 61 returns to its initial position and waits for the next push-unloading operation. In this way, through the coordinated operation of the push plate 65, the connecting rod 63, the push plate 61 and the third compression spring 64, the function of conveniently pushing and unloading objects inside the fixed shell 2 is realized.

[0033] The tail wire protection assembly 5 includes a baffle 52 and a second protective plate 54. A second compression spring 56 is fixedly installed on one side of the baffle 52, and an insert block 57 is fixedly installed on the other side of the baffle 52. A first protective plate 53 is fixedly installed on the lower surface of the baffle 52. The second protective plate 54 is fixedly installed on the outer wall of the bottom of the fixed shell 2. Protective sponge 55 is provided on the outer walls of the first protective plate 53 and the second protective plate 54. One end of the baffle 52 is provided with an arc, and one end of the insert block 57 is provided with a slope. The arc and the slope are connected. A sliding groove 51 is opened on one side of the through groove 3. The other end of the second compression spring 56 is fixedly installed on the inner wall of the sliding groove 51. A slot 58 is opened on the sliding groove 51, and an insertion port is opened on the other side of the through groove 3.

[0034] In the integrated miniature photoelectric switch of this utility model, when the tail wire needs to be installed or passed through the through slot 3, the tail wire squeezes the end of the baffle 52 with an arc. Since the arc is connected to the inclined surface of the insert 57, under the compression of the tail wire, the baffle 52 is forced to move into the slide groove 51, and the second compression spring 56 is compressed. At this time, the insert 57 is withdrawn from the socket, the through slot 3 is opened, and the tail wire can pass through the through slot 3 smoothly. After the tail wire passes through, under the elastic force of the second compression spring 56 to restore its original state, the baffle 52 moves back to the through slot 3, and the insert 57 is reset. The insertion port closes the through slot 3. The first protective plate 53 moves with the baffle 52, and the second protective plate 54 is fixed to the bottom of the fixed shell 2. The two form an upper and lower clamping space. The protective sponge 55 covers the outer walls of both and directly wraps the tail wire. The soft material prevents the wire from being worn or broken, and prevents the tail wire from accidentally slipping out or being pulled by the outside. This design not only protects the tail wire, but also ensures the stability and reliability of the tail wire during use, effectively extends the service life of the tail wire, and reduces the risk of photoelectric switch failure due to loose or damaged tail wire.

[0035] Working principle: The photoelectric switch body 1 is pushed into the fixed shell 2 for installation. The side wall of the photoelectric switch body 1 presses against the side pressure plate 47, which in turn presses against the first compression spring 46, compressing it. The elastic force generated by the first compression spring 46 pushes the side pressure plate 47 to press against both sides of the photoelectric switch body 1. The top of the photoelectric switch body 1 simultaneously presses against the upper pressure plate 41, causing the upper pressure plate 41 to move upward. The upper pressure plate 41 drives the tension spring 43 to stretch via the vertical rod 42, causing the tension spring 43 to stretch. The elastic force generated by the tension spring 43 forces the upper pressure plate 41 downward via the vertical rod 42, thus pressurizing the top of the photoelectric switch body 1. The tail wire at the bottom of the photoelectric switch body 1 presses against the baffle 52, causing the baffle 52 to retract into the slide groove 51. The baffle 52 simultaneously compresses the second compression spring 56, causing the second compression spring 56 to be in a compressed state. The baffle 52 drives the first protective plate 53 to move into the slot 58. When the tail wire moves to the innermost part of the through slot 3, the tail wire no longer compresses the baffle 52. The baffle 52 is reset by the elastic force of the second compression spring 56. The insert 57 is reinserted into the slot opened on the other side of the through slot 3. The first protective plate 53 and the second protective plate 54 wrap the tail wire. When disassembly is required, simply press the button 65. The button 65 drives the push plate 61 to move through the connecting rod 63. The push plate 61 is removed from the groove 62. The push plate 61 pushes the photoelectric switch body 1 and simultaneously presses the baffle 52, causing the baffle 52 to retract into the slide groove 51. The first protective plate 53 and the second protective plate 54 are separated, allowing the photoelectric switch body 1 to be removed from the fixed shell 2, completing the disassembly.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
