Description

Technical Field

[0001] The utility model relates to the technical field of laser sensors, in particular to a dustproof laser sensor. Background Art

[0002] Laser sensor is a sensor that uses laser technology for measurement. It is based on the principle of optical measurement and obtains information about the target object by emitting a laser beam and detecting its reflected or scattered light. Laser sensors have the characteristics of high precision, high speed, and non-contact measurement, and are widely used in various fields.

[0003] Publication No. CN212721472U discloses a laser sensor with high-temperature protection, including a laser sensor body, wherein the laser sensor body includes a first functional layer, a base layer, a strengthening layer and a tungsten alloy layer, wherein the first functional layer includes a high-temperature alloy layer, a titanium alloy layer and a nickel-tungsten alloy layer, wherein the high-temperature alloy layer is located on the top of the titanium alloy layer and is fixedly connected, wherein the top of the nickel-tungsten alloy layer is fixedly connected to the bottom of the titanium alloy layer, wherein the thickness of the high-temperature alloy layer is greater than the thickness of the titanium alloy layer, and the thickness of the nickel-tungsten alloy layer is greater than the thickness of the high-temperature alloy layer.

In addition, since the surface of the laser head will still retain a certain residual temperature after stopping, it is also easy to attract some insects to enter the laser head, thereby affecting the subsequent use of the laser head.

The upper end of the first screw rod 602 rotates and extends into the inner side of the second mounting groove 605 to be fixedly installed with a first bevel gear 604. The first bevel gear 604 is meshedly connected to one end of a transmission member 606, and the other end of the transmission member 606 is meshedly connected to the linkage mechanism 8.

[0033] See also Figure 3 A slide groove 9 is symmetrically provided on the inner side of the first mounting groove 601, one end of the rod body 603 is slidably connected to the inner side of the first mounting groove 601 through the slide groove 9, a nut sleeve 10 is fixedly installed on the inner side of the upper end of the rod body 603, one end of the first screw rod 602 is threadedly connected to the inner side of the nut sleeve 10, and the first screw rod 602 is rotated at the first mounting groove 601, so that the lower end of the first screw rod 602 is threadedly connected to the rod body 603 with the nut sleeve 10, and the rod body 603 slides vertically up and down at the slide groove 9 of the first mounting groove 601.

[0034] See also Figure 8 The upper end of the mounting frame 701 is symmetrically fixedly connected with a connecting block 13, and the end of the connecting block 13 away from the mounting frame 701 is plugged and connected with the lower end of the rod body 603. A screw hole 14 is provided on the inner side of the connecting block 13, and the lower end of the rod body 603 is fixedly installed by screws and screw holes 14. When the mounting frame 701 is connected to the rod body 603, the connecting block 13 at the upper end of the mounting frame 701 is plugged into the connecting groove at the lower end of the rod body 603, and then the screws are extended from the outside of the rod body 603 into the connecting groove and the screw hole 14 on the mounting frame 701 for installation, thereby facilitating the connection and installation of the dustproof part 7 and the telescopic rod 6 structure.

[0035] The working principle of the utility model is as follows: when in use, the laser sensor body 1 can be conveniently installed on a designated device through the mounting plate 3 with mounting holes 4 on the laser sensor body 1. During use, when the laser sensor body 1 is stopped, first, the output end of the first drive motor 707 drives the second screw 703 to rotate at the through hole 702 in the mounting frame 701. Due to the rotation of the second screw 703, the dustproof head 705 connected with the outer thread slides to the right below the laser head 5;

[0036] Then, the output end of the second driving motor 801 is used to drive the second shaft rod 802 to rotate inside the through groove 803, and the rotation of the second shaft rod 802 allows the second bevel gear 804 on the outside to synchronously mesh with the transmission bevel gear 6063 on one end of the first shaft rod 6062 to rotate synchronously. At the same time, the transmission bevel gear 6063 on the other end of the first shaft rod 6062 meshes with the transmission first bevel gear 604, and the rotation of the first bevel gear 604 allows the connected first screw rod 602 to rotate at the first mounting groove 601. Due to the rotation of the first screw rod 602, the rod body 603 connected with the outer thread slides at the first mounting groove 601, and the rod body 603 drives the mounting frame 701 to move toward the direction of the laser head 5, and at the same time, the dustproof slot 704 with the sponge block 706 on the dustproof head 705 can be plugged into the lower end of the laser head 5 for protection;

[0037] On the contrary, when the laser sensor body 1 is used, the second drive motor 801 first runs in reverse, indirectly causing the rod body 603 to drive the mounting bracket 701 away from the laser head 5. Then, the output end of the first drive motor 707 drives the second screw 703 to run in reverse. At this time, the dustproof head 705 threadedly connected to the outer side of the second screw 703 is moved away from directly below the laser head 5. Subsequently, the rod body 603 drives the mounting bracket 701 to rise, so that the lower end of the laser head 5 extends into the through hole 702 of the mounting bracket 701. At this time, the laser head 5 can be used normally.
