Description

Technical Field

[0001] The utility model belongs to the technical field of sensor protection devices, and in particular relates to a sensor transmitting end protection device and a laser sensor. Background Art

[0002] Laser sensors utilize laser technology for measurement. Laser sensors emit laser light from the transmitter, enabling contactless, long-distance measurement. They offer high speed, high accuracy, a wide range, and strong resistance to interference from light and electricity. Laser sensors are typically sealed to protect their internal components, while the transmitter is typically exposed to the air to facilitate laser transmission. Some laser sensors also incorporate transparent glass to seal the transmitter.

[0003] The existing laser sensor transmitter protection devices on the market have the following disadvantages: usually, a protective cover made of transparent glass is directly used to protect the top of the laser sensor during use. The protective cover cannot be removed during use. During long-term protection, the protective cover is prone to a large amount of debris being attached, affecting the accuracy of the laser sensor, making it inconvenient to use.

[0004] After searching, the existing patent (publication number: CN217818784U) discloses a laser sensor emitting end protection device, including a laser emitting end and a protection component, which is movably installed on the outside of the laser emitting end. The protection component is specifically composed of a slide rail, an L-shaped slot, a protective cover, an L-shaped slider, a limit spring and a base plate. The laser emitting end is inserted into the protective cover, and L-shaped sliders are installed on both sides of the bottom end of the protective cover and connected to the base plate through the limit spring. The L-shaped slider is slid longitudinally in the slide rail and inserted into the L-shaped slot, so that the laser emitting end can be protected by the protective cover and the laser emitting end can be easily popped out of the protective cover for use.

[0005] However, there are still some shortcomings in the above structure. The protective component on the protective device of the laser sensor transmitting end is exposed, which is inconvenient to use. In addition, the shape of the protective component is relatively complex, and it is easy to get stuck when it is inserted into the L-shaped slot, making it difficult to operate.

[0006] Therefore, it is necessary to provide a new sensor transmitting end protection device and laser sensor to solve the above technical problems. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a sensor transmitting end protection device and a laser sensor which can protect the transmitting end and are easy to operate.

[0008] In order to solve the above technical problems, the sensor transmitting end protection device provided by the present invention includes: a protection shell and a cover shell, and the protection shell is provided with a protection mechanism:

[0009] The protective mechanism includes four positioning blocks, each of which is fixedly connected to the outer wall of the cover shell, a transmitting end body is fixedly installed in the protective shell, a movable groove corresponding to the four positioning blocks is provided on the protective shell, a slot corresponding to the four positioning blocks is provided on the inner wall of the protective shell, four slide grooves are provided on the inner wall of the protective shell, a movable column is slidably installed in the slide groove, the corresponding four movable columns are fixedly connected to a top ring, a fixed ring tube is slidably sleeved on the movable column, one side surface of the fixed ring tube is fixedly connected to the inner wall of the protective shell, a spring is sleeved on the movable column, one end of the spring is fixedly connected to the other side surface of the fixed ring tube, the other end of the spring is fixedly connected to one side surface of the top ring, and the rear end of the protective shell is fixedly connected to a connecting line:

[0010] As a further solution of the present invention, the sliding sleeve on the cover shell is provided with a collar, and a sealing plate adapted to the four movable grooves is fixedly connected to a surface of one side of the collar.

[0011] As a further solution of the present invention, circular sliding grooves corresponding to the four movable grooves are provided on the cover shell, and sliding columns adapted to the four circular sliding grooves are fixedly connected to the inner surface of the ring, and the sliding columns are slidably connected to the circular sliding grooves.

[0012] As a further solution of the present invention, both side surfaces of the positioning block are inclined surfaces, and the size of the card slot is adapted to the size of the positioning block.

[0013] As a further solution of the present invention, the position of the top ring corresponds to the position of the cover shell, and the size of the top ring is smaller than the size of the cover shell.

[0014] The utility model also provides a laser sensor, comprising: a laser sensor body, a mounting hole being provided on the laser sensor body, a transmission line being fixedly connected to the rear surface of the laser sensor body, two mounting grooves being provided on the laser sensor body, and mounting ears being fixedly connected to the mounting grooves by screws.

[0015] Compared with related technologies, the sensor transmitting end protection device and laser sensor provided by the present invention have the following beneficial effects:

[0017] 2. The utility model sets a sealing plate. After the positioning block is inserted into the card slot, the sealing plate is moved into the movable slot to seal the movable slot and prevent dust from entering the movable slot. The sealing plate can be conveniently inserted into the movable slot through the setting of the circular slide groove and the slide column. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the sensor transmitter protection device provided by the utility model; Figure 2 A schematic diagram of the internal structure of the protective shell of the sensor transmitting end protection device provided by the present invention; Figure 3 This is a schematic diagram of the top ring structure of the sensor transmitting end protection device provided by the utility model; Figure 4This is a schematic diagram of the main structure of the laser sensor provided by the utility model. The sensor transmitting end protection device includes: a protective shell 1 and a cover shell 2, and the protective shell 1 is provided with a protective mechanism:

[0025] The protective mechanism includes four positioning blocks 3, which are fixedly connected to the outer wall of the cover shell 2. A transmitting end body 4 is fixedly installed in the protective shell 1. A movable groove 5 corresponding to the four positioning blocks 3 is provided on the protective shell 1. A slot 6 corresponding to the four positioning blocks 3 is provided on the inner wall of the protective shell 1. Four slide grooves 7 are provided on the inner wall of the protective shell 1. A movable column 8 is slidably installed in the slide groove 7. The corresponding four movable columns 8 are fixedly connected to a top ring 9. A fixed ring tube 10 is slidably sleeved on the movable column 8. One side surface of the fixed ring tube 10 is fixedly connected to the inner wall of the protective shell 1. A spring 11 is sleeved on the movable column 8. One end of the spring 11 is fixedly connected to the other side surface of the fixed ring tube 10, and the other end of the spring 11 is fixedly connected to one side surface of the top ring 9. The rear end of the protective shell 1 is fixedly connected to a connecting line 12.

[0026] like Figure 2 As shown, a collar 13 is provided on the cover shell 2 for sliding, and a sealing plate 14 adapted to the four movable grooves 5 is fixedly connected to one side surface of the collar 13;

[0027] By providing the sealing plate 14 , after the positioning block 3 is inserted into the card slot 6 , the sealing plate 14 is moved into the movable slot 5 , thereby sealing the movable slot 5 and preventing dust from entering the movable slot 5 .

[0028] like Figure 2 As shown, the cover shell 2 is provided with circular chute 15 corresponding to the four movable grooves 5, and the inner surface of the collar 13 is fixedly connected with a slide post 16 adapted to the four circular chute 15, and the slide post 16 is slidably connected to the circular chute 15;

[0029] By setting the circular slide groove 15 and the slide column 16, the sealing plate 14 can be positioned, so that after the positioning block 3 is inserted into the slot 6, the sealing plate 14 can automatically align with the position of the movable slot 5 following the rotation of the cover shell 2, and then the ring 13 is slid toward the protective shell 1 to drive the sealing plate 14 to be inserted into the movable slot 5 to complete the sealing work.

[0030] like Figure 2 As shown, both side surfaces of the positioning block 3 are inclined surfaces, and the size of the slot 6 is adapted to the size of the positioning block 3;

[0031] By setting the positioning block 3, after the cover shell 2 is inserted into the movable slot 5, the cover shell 2 is rotated to move the positioning block 3 to the position of the slot 6, and then the cover shell 2 is released. The cover shell 2 pushes the positioning block 3 into the slot 6 under the rebound of the spring 11. During this period, if the position of the positioning block 3 is not completely aligned with the slot 6, the inclined surface of the positioning block 3 contacts the positioning block 3, thereby guiding the positioning block 3 so that the position of the positioning block 3 can be smoothly inserted into the slot 6 even with a certain error, thereby reducing the difficulty of installing the cover shell 2 and facilitating operation by users.

[0032] like Figure 2 As shown, the position of the top ring 9 corresponds to the position of the cover shell 2, and the size of the top ring 9 is smaller than the size of the cover shell 2;

[0033] By setting the size of the top ring 9 to be smaller than the size of the cover shell 2, the top ring 9 will not contact the inner wall of the protective shell 1 when it rebounds, thereby avoiding the top ring 9 from getting stuck.

[0034] The working principle of the sensor transmitting end protection device provided by the utility model is as follows:

[0035] First, align the positioning block 3 with the movable groove 5, insert the cover shell 2 into the movable groove 5, and after the positioning block 3 hits the top ring 9, continue to press inward to move, driving the movable column 8 to move in the slide groove 7 while compressing the spring 11. Then, after the positioning block 3 reaches the innermost part, rotate the cover shell 2, move the positioning block 3 to the position of the slot 6, and release the cover shell 2. The cover shell 2 pushes the positioning block 3 into the slot 6 under the rebound of the spring 11. During this period, if the position of the positioning block 3 is not completely aligned with the slot 6, the inclined surface of the positioning block 3 and the positioning block 3 will be in contact with each other. The positioning block 3 contacts the positioning block 3, thereby guiding the positioning block 3, so that the positioning block 3 can be smoothly inserted into the card slot 6 even with a certain error, reducing the installation difficulty of the cover shell 2, and at the same time protecting the transmitter body 4. The transmitter body 4 exposed to the outside can also be protected by the cover shell 2. When the positioning block 3 is inserted into the card slot 6, the sealing plate 14 follows the rotation of the cover shell 2 to move to the position corresponding to the movable groove 5, and then the ring 13 is moved to drive the sealing plate 14 to be inserted into the movable groove 5 to seal the movable groove 5.

[0036] The present utility model also provides a laser sensor, comprising: a laser sensor body 17, a mounting hole 18 being provided on the laser sensor body 17, a transmission line 19 being fixedly connected to the rear surface of the laser sensor body 17, two mounting grooves 21 being provided on the laser sensor body 17, and mounting ears 20 being fixedly connected to the mounting grooves 21 by screws.

[0037] The working principle of the laser sensor provided by this utility model is as follows:

[0038] First, align the mounting ear 20 with the mounting slot 21, insert the protective shell 1 into the mounting hole 18, and then screw the screw into the mounting ear 20 to fix the mounting ear 20 on the mounting slot 21, thereby completing the installation of the protective shell 1. Conversely, the protective shell 1 can be removed from the laser sensor body 17, which facilitates the maintenance and installation of the protective shell 1.
