Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric induction devices, and specifically relates to a square photoelectric induction device. Background Technique

[0002] A photoelectric induction device is a sensor device that uses the photoelectric effect to detect the presence of an object or measure the characteristics of an object. The photoelectric induction device mainly consists of two components: a light emitter and a light receiver. The light emitter is responsible for emitting light, and usually uses a general light bulb, a red LED, a green LED, an infrared LED, etc. as the light source; the light receiver is responsible for receiving the light emitted by the light emitter and converting it into an electrical signal. The main component of the light receiver is a photoelectric element, such as a photodiode, etc.

[0003] The working principle of the photoelectric induction device is based on the photoelectric effect, that is, when light irradiates the surface of a substance, the phenomenon that the substance releases electrons. When the light emitted by the light emitter is blocked or reflected by an object, the light signal received by the light receiver will change, and then an electrical signal is generated. This electrical signal can be further processed to achieve various automatic control functions. The shapes of photoelectric induction devices are diverse, such as square photoelectric induction devices, etc. Due to their characteristics such as high sensitivity, fast response, and non-contact measurement, photoelectric induction devices are widely used in various fields.

[0004] Currently, when using a square photoelectric induction device, it is usually necessary to select a suitable position for installation according to actual needs to ensure that it is aligned with the target to be detected, and then wire and power the square photoelectric induction device, and simultaneously conduct a simple test on it to ensure the normal operation of the device, then the square photoelectric induction device can be used.

[0005] Since the square photoelectric induction device needs to be aligned with the target to be detected after being fixedly installed, if it is found that it is not aligned, the device needs to be disassembled and reinstalled, which is rather troublesome and likely to affect work efficiency. Content of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide a square photoelectric induction device to solve the technical problem that after the square photoelectric induction device is fixedly installed, it is necessary to align it with the target to be detected. If it is found that it is not aligned, the device needs to be disassembled and reinstalled, which is rather troublesome and likely to affect work efficiency.

[0007] To achieve the above object, the present utility model provides the following technical solution: A square photoelectric induction device, including a bottom plate, a set of fixed blocks are fixedly connected to one side of the bottom plate, each fixed block is provided with a first chute, and a first slider that fits the first chute is slidably connected in each first chute. The top of a set of the first sliders is fixedly connected to a connecting block, a second chute is provided on the top of the connecting block, and a second slider that fits the second chute is slidably connected in the second chute. One side of the second slider is connected to the photoelectric induction device body at the bottom. Rack bars are fixedly connected to both sides of each of the first chute and the second chute, a pressing block is slidably connected to one side of each of the first slider and the second slider, an active block is fixedly connected to the bottom of each pressing block, and a set of symmetric elastic blocks are fixedly connected to one side of each of the first slider and the second slider close to the pressing block. Each active block slides between a corresponding set of elastic blocks, and a number of tooth blocks that fit the rack bars are fixedly connected to one side of each elastic block.

[0008] By adopting the above technical solution, after the installation of the photoelectric induction device body is completed and it is found that its position is not aligned with the target to be detected, the pressing block and the corresponding active block can be slid to move until the active block no longer supports a set of elastic blocks, thereby driving the first slider to slide in the first chute and the second slider to slide in the second chute, so that the rack bar squeezes the corresponding tooth blocks and elastic blocks, causing the elastic blocks to deform and thus changing the position of the tooth blocks, enabling the adjustment of the positions of the first slider and the second slider, and thus realizing the adjustment of the position of the photoelectric induction device body. When fixing the position of the photoelectric induction device body, the corresponding pressing block and active block can be slid so that the active block is located between a corresponding set of elastic blocks, thereby supporting the set of elastic blocks and preventing them from deforming due to external forces. Moreover, the tooth blocks on the outer surface of the elastic blocks fit the corresponding rack bars, enabling the fixation of the positions of the first slider and the second slider, and thus fixing the position of the photoelectric induction device body. This structure can accurately adjust the position of the photoelectric induction device body after installation, and the operation is simple and convenient to improve the effect.

[0009] The present utility model is further configured such that a set of grooves are provided on one side of each of the first slider and the second slider, a slide bar that fits the groove is slidably connected in each groove, each slide bar is of a "T" - shaped structure, and one end of each set of slide bars is fixedly connected to the corresponding pressing block.

[0010] By adopting the above technical solution, the position of the slide bar and the pressing block during sliding can be limited by the groove. At the same time, due to the high degree of fit between the groove and the slide bar, the position of the slider can be accurately controlled, thereby better driving the active block to move.

[0011] The present utility model is further configured such that a plurality of bumps are fixedly connected to the top of the pressing block, and a handle is installed on one side of the pressing block.

[0012] By adopting the above technical solution, the setting of the bumps can increase the area of contact between the pressing block and the contact surface, thereby increasing the friction force. Therefore, the pressing block can be better pushed to move. At the same time, the setting of the handle enables the operator to pull the pressing block to move through it, facilitating the improvement of the operation convenience.

[0013] The present utility model is further configured such that positioning holes are provided at the four corners of the bottom plate, and a rubber pad is provided on the side of the bottom plate away from the photoelectric induction device body.

[0014] By adopting the above technical solution, fixing parts such as bolts can be installed in the positioning holes to complete the fixation of the bottom plate, facilitating the rapid installation of the photoelectric induction device body. At the same time, the rubber pad can make the bottom plate fit tightly with the contact surface, contributing to a more firm connection.

[0015] The present utility model is further configured such that a receiving groove is provided on one side of each of the first slider and the second slider close to the pressing block, and the receiving groove is fitted with the movable block.

[0016] By adopting the above technical solution, the movable block can be embedded in the receiving groove, thereby playing a role in receiving the movable block and preventing the movable block from being located between a group of elastic blocks, thus affecting the deformation of the elastic blocks.

[0017] The present utility model is further configured such that each of the elastic blocks is of an "L" - shaped structure.

[0018] By adopting the above technical solution, the position of the movable block can be limited, so that it will not slide out from the middle of a group of elastic blocks. Then, the movable block can play a supporting role for a group of elastic blocks, preventing the elastic blocks from deforming.

[0019] The present utility model is further configured such that scale lines are provided on the tops of a group of the fixing blocks and the connecting blocks.

[0020] By adopting the above technical solution, it is convenient for the operator to more accurately adjust the position of the photoelectric induction device body, thereby improving the accuracy of the position of the photoelectric induction device body.

[0021] In summary, the present utility model mainly has the following beneficial effects:

[0022] In the present utility model, a pressing block is slidably connected to the first slider, and a movable block is fixedly connected to the bottom of the pressing block. Therefore, when the pressing block drives the movable block to move to a position where it does not support the elastic block, the first slider and the second slider can move. At this time, the racks in the first chute and the second chute squeeze the corresponding gear blocks and elastic blocks, causing the elastic blocks to deform and thus changing the positions of the gear blocks. Then, the positions of the first slider and the second slider can be adjusted, thereby adjusting the position of the photoelectric induction device body. And when the pressing block drives the movable block to move between a corresponding group of elastic blocks, the movable block can support a group of elastic blocks, preventing the elastic blocks from deforming due to external forces, and making the gear blocks on the outer surfaces of the elastic blocks fit with the racks. Therefore, the positions of the first slider and the second slider can be fixed, thereby fixing the position of the photoelectric induction device body. This device can accurately adjust the position of the photoelectric induction device body after installation, and the operation is simple, which is convenient for improving work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] A square photoelectric induction device, such as Figures 1-5 shown, includes a bottom plate 1. Positioning holes 2 are provided at the four corners of the bottom plate 1. The installation of the bottom plate 1 can be completed by arranging fixing parts, such as bolts, in the positioning holes 2. A rubber pad 3 is provided on the side of the bottom plate 1 away from the photoelectric induction device body 19, which can make the bottom plate 1 fit tightly with the contact surface and help to make the connection more firm.

[0032] Then, a group of fixing blocks 4 are fixedly connected to one side of the bottom plate 1. A first sliding groove 5 is provided in each fixing block 4. A first sliding block 6 that fits with the first sliding groove 5 is slidably connected in each first sliding groove 5. The tops of a group of first sliding blocks 6 are fixedly connected to a connecting block 18. By sliding the first sliding block 6 in the corresponding first sliding groove 5, the position of the connecting block 18 can be adjusted. A second sliding groove 16 is provided at the top of the connecting block 18. A second sliding block 17 that fits with the second sliding groove 16 is slidably connected in the second sliding groove 16. One side of the second sliding block 17 is connected to the photoelectric induction device body 19. Then, the position of the photoelectric induction device body 19 can be changed by sliding the second sliding block 17 in the second sliding groove 16. Therefore, the position of the photoelectric induction device body 19 in the vertical and horizontal directions can be changed through the first sliding groove 5 and the first sliding block 6, and the second sliding groove 16 and the second sliding block 17, so that it can be accurately aligned with the target to be detected.

[0033] Meanwhile, racks 7 are fixedly connected to both sides inside each of the first sliding grooves 5 and the second sliding grooves 16. A pressing block 12 is slidably connected to one side of each of the first sliding blocks 6 and the second sliding blocks 17. An active block 13 is fixedly connected to the bottom of each pressing block 12. Thus, the active block 13 can be driven to move by the pressing block 12. A set of symmetric elastic blocks 8 are fixedly connected to one side of each of the first sliding blocks 6 and the second sliding blocks 17 close to the pressing block 12. Each active block 13 slides between a corresponding set of elastic blocks 8. A number of tooth blocks 9 that fit with the racks 7 are fixedly connected to one side of each elastic block 8. Therefore, when the pressing block 12 drives the active block 13 to move to the middle of a corresponding set of elastic blocks 8, the active block 13 can support a set of elastic blocks 8, preventing the elastic blocks 8 from deforming due to external forces, so that the tooth blocks 9 mesh with the racks 7, making the corresponding first sliding block 6 or second sliding block 17 unable to move, thereby fixing the position of the photoelectric induction device body 19. When the active block 13 moves to a position where it does not support the elastic block 8, the sliding of the first sliding block 6 or the second sliding block 17 causes the rack 7 to squeeze the tooth block 9 and the corresponding elastic block 8, causing the elastic block 8 to deform, thereby driving the tooth block 9 to move. Therefore, it does not affect the movement of the first sliding block 6 or the second sliding block 17, and thus the position of the photoelectric induction device body 19 can be adjusted. This structure can accurately adjust the position of the photoelectric induction device body 19 after installation, and the operation is simple, facilitating the improvement of work efficiency.

[0034] Furthermore, a set of grooves 10 are provided on one side of each of the first sliding blocks 6 and the second sliding blocks 17. A sliding rod 11 that fits with the groove 10 is slidably connected inside each groove 10. One end of each set of sliding rods 11 is fixedly connected to the corresponding pressing block 12. Then, when the sliding rod 11 slides in the groove 10, the corresponding pressing block 12 can be driven to move synchronously. Each sliding rod 11 is set in a "T" - shaped structure, which can increase the stability of the sliding of the sliding rod 11 and limit the movement direction of the sliding rod 11. At the same time, a damping structure is provided between the groove 10 and the sliding rod 11. Therefore, when the external force is small, the sliding rod 11 cannot be driven to move, avoiding affecting the use of the device.

[0035] Among them, a storage groove 14 is provided on one side of each of the first sliding blocks 6 and the second sliding blocks 17 close to the pressing block 12. The storage groove 14 fits with the active block 13. The active block 13 can be embedded into the storage groove 14, thus realizing the storage of the active block 13, preventing the active block 13 from supporting a corresponding set of elastic blocks 8. Each elastic block 8 is set in an "L" - shaped structure, which can limit the position of the active block 13, preventing it from sliding out from the middle of a corresponding set of elastic blocks 8 and affecting the use, and facilitating the active block 13 to better support a corresponding set of elastic blocks 8.

[0036] In this embodiment, several bumps 21 are fixedly connected to the top of the pressing block 12, so that the area of contact between the pressing block 12 and the contact surface can be increased, thereby increasing the friction between the two. Therefore, the pressing block 12 can be better pushed to move. A handle 15 is installed on one side of the pressing block 12, enabling the operator to pull the handle 15 to drive the pressing block 12 to move, which is convenient for improving the operation convenience. At the same time, scale lines 20 are provided on the tops of a set of fixed blocks 4 and connecting blocks 18, which can more accurately adjust the position of the photoelectric induction device body 19, so that the photoelectric induction device body 19 is aligned with the object to be detected, facilitating better use of the device.

[0037] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention and not a limitation thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
