It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0029] The following will be further described in detail with reference to the attached Figures 1 - 6 This embodiment will be further described in detail.

[0030] Combined with Figures 1 - 6 As shown, a lens protective cover in this embodiment includes a protective cover 100 covering the lens of an industrial camera 10. One end of the protective cover 100 is provided with a transparent plate 250, and a detachable cleaning assembly for cleaning the transparent plate 250 is provided outside the protective cover 100; the cleaning assembly includes a cleaning cover 110. One end of the cleaning cover 110 is provided with a rotatable cleaning member for rotatably cleaning the transparent plate 250. The cleaning member includes a mounting plate 120 rotatably arranged in the cleaning cover 110. A sponge pad 310 is arranged on one side of the mounting plate 120. The rotation of the mounting plate 120 is used to make the sponge pad 310 wipe the transparent plate 250 rotationally. The cleaning cover 110 is detachably mounted outside the protective cover 100 through a fixing assembly.

[0031] In actual use of this embodiment, both ends of the protective cover 100 are open. The transparent plate 250 is fixedly installed at the opening at one end of the protective cover 100. The other end of the protective cover 100 is fixedly covered outside the lens of the industrial camera 10. The transparent plate 250 is made of a transparent material, so that the protective cover 100 can play a certain protective role for the lens of the industrial camera 10, avoiding dust from falling on the lens of the industrial camera 10. At the same time, the lens of the industrial camera 10 can work through the transparent plate 250;

[0032] In this embodiment, during the use of the industrial camera 10, it is not necessary to disassemble the protective cover 100, so that dust will not directly fall on the lens of the industrial camera 10. However, due to the use of the protective cover 100, dust will fall on the transparent plate 250, affecting the actual use of the transparent plate 250. Among them, through the setting of the cleaning component, when the cleaning cover 110 covers the outside of the protective cover 100, the cleaning member can clean the transparent plate 250, thereby better avoiding dust adhering to the transparent plate 250 and affecting the actual use of the industrial camera 10.

[0033] Among them, in order to prevent the cleaning cover 110 and the cleaning member from interfering with the use of the transparent plate 250, the cleaning cover 110 is detachably installed outside the protective cover 100 through a fixing component.

[0034] In its actual use, both ends of the cleaning cover 110 are open, the cleaning member is arranged at one end opening thereof, and the other end opening of the cleaning cover 110 covers the outside of the protective cover 100. When the cleaning cover 110 covers the outside of the protective cover 100, the cleaning member can fit the outside of the transparent plate 250, so that the cleaning member can rotate and wipe the transparent plate 250, thereby being able to better wipe the transparent plate 250.

[0035] Among them, through the setting of the mounting plate 120 and the sponge pad 310, the sponge pad 310 can be installed on one side surface of the mounting plate 120 by pasting. The sponge pad 310 fits the outside of the transparent plate 250, and the size of the sponge pad 310 is adapted to that of the transparent plate 250. Thus, rotating the mounting plate 120 can drive the sponge pad 310 to rotate, so that the sponge pad 310 can rotate and wipe the transparent plate 250.

[0036] In this embodiment, as shown in Figure 3 a circular groove 300 is provided on the outer side wall of the mounting plate 120 along its circumference, and a convex block 400 that is snapped into the circular groove 300 and slides is provided on the inner side wall of the cleaning cover 110 through screws.

[0037] In this embodiment, through the setting of the circular groove 300 and the convex block 400, when the convex block 400 is snapped into the circular groove 300, the mounting plate 120 can be rotated around the convex block 400. In actual installation, the convex block 400 is in two sections, which are butt - installed in the circular groove 300. Then, the sponge pad 310 is oriented towards the transparent plate 250, and the mounting plate 120 is inserted into the cleaning cover 110 from one end opening. Then, screws are passed through the cleaning cover 110 and screwed into the convex block 400, so as to fix the convex block 400 inside the cleaning cover 110, thereby enabling the mounting plate 120 to be rotatably installed at one end opening of the cleaning cover 110.

[0038] Among them, in order to facilitate the operator to rotate the mounting plate 120, a knob 130 is installed on the other side wall of the mounting plate 120 by bonding. Through the setting of the knob 130, the operator can easily rotate the mounting plate 120 to drive the sponge pad 310 to rotate and wipe the transparent plate 250, thereby improving its practicality.

[0039] Combination Figures 2 - 5 As shown, in this embodiment, a placement cavity 420 is relatively provided on the outer wall of the protective cover 100; the fixing component includes a pin 210 arranged in the placement cavity 420 through a spring 510, and the spring 510 is used to push the pin 210 to move upward so that its upper end extends out of the protective cover 100, and a slope 220 is provided on the protruding end of the pin 210, and a positioning hole 600 for the corresponding pin 210 to extend into is provided on the outer wall of the cleaning cover 110. When the cleaning cover 110 is slidably sleeved on the outside of the protective cover 100, the end of the cleaning cover 110 squeezes the slope 220 to realize the automatic insertion of the pin 210 into the corresponding positioning hole 600.

[0040] In actual use, if Figure 5 As shown, the upper end of the placement cavity 420 is open. In order to install the pin 210 in the placement cavity 420, the side wall of the placement cavity 420 is relatively provided with a cavity 430 along its extension direction. The outer side wall of the pin 210 is provided with a limit rod 440 extending into the corresponding cavity 430 for sliding. A step groove 500 is provided at the opening position of the cavity 430. A sealing plate 200 is installed in the step groove 500 by screws. Through the setting of the sealing plate 200, the sealing plate 200 can block the cavity 430, so that the limit rod 440 will not be separated from the cavity 430, so that the pin 210 is installed in the placement cavity 420 through the spring 510.

[0041] The limiting rod 440 and the cavity 430 are adapted to each other, so that the limiting rod 440 will not rotate in the cavity 430, and the pin 210 will not shake, so that the inclined surface 220 can always face the cleaning cover 110.

[0042] In the process of the cleaning cover 110 slidingly installed outside the protective cover 100 along the outer wall of the protective cover 100, the end of the cleaning cover 110 can abut against the inclined surface 220, so that the cleaning cover 110 can press the inclined surface 220 to move downward, driving the pin 210 to retract into the placement cavity 420. When the cleaning cover 110 continues to move, driving the positioning hole 600 to slide to the opening position of the placement cavity 420, the spring 510 can push the pin 210 to move upward and pass through the positioning hole 600, so that the cleaning cover 110 can be fixedly installed on the protective cover 100.

[0043] In actual use, in order to better align the positioning hole 600 with the pin 210, a guide groove 230 is provided on the outer wall of the protective cover 100 along its length direction, and a guide block for sliding into the guide groove 230 is provided on the inner wall of the cleaning cover 110;

[0044] The pin 210 is adapted to the placement cavity 420 so that the pin 210 does not shake in the placement cavity 420, thereby allowing the spring 510 to drive the pin 210 to better extend into the positioning hole 600;

[0045] Among them, the pin 210 is adapted to the positioning hole 600, so that the outer wall of the pin 210 can fit with the side wall of the positioning hole 600, so that the pin 210 will not shake in the positioning hole 600, so that the cleaning cover 110 will not shake outside the protective cover 100, so that the cleaning cover 110 can be better fixed on the protective cover 100.

[0046] Combination Figure 6 As shown, in this embodiment, a positioning column 140 is slidably provided in the positioning hole 600, a sliding groove 610 with an opening toward the cleaning cover 110 is relatively provided on the side wall of the positioning hole 600, a blocking block 620 is provided at the opening of the sliding groove 610, a sliding block 450 extending into the sliding groove 610 and sliding is relatively provided on the side wall of the positioning column 140, and a push column 630 is provided at the lower end of the positioning column 140. The downward movement of the positioning column 140 is used to enable the push column 630 to squeeze the upper end of the pin 210 to make it disengage from the positioning hole 600.

[0047] In this embodiment, the positioning column 140, the sliding groove 610 and the slider 450 are arranged so that the positioning column 140 can move up and down in the positioning hole 600. The upper end of the push column 630 is connected to the lower end surface of the positioning column 140 by welding. The lower end surface of the push column 630 is adapted to the upper end of the pin 210, so that the positioning column 140 can push the push column 630 to move downward, so that the push column 630 can squeeze the upper end of the pin 210 extending into the positioning hole 600, thereby making the pin 210 disengage from the positioning hole 600 and retract into the placement cavity 420, thereby releasing the fixation of the cleaning cover 110.

[0048] The opening of the sliding groove 610 faces the inside of the cleaning cover 110, so that the slider 450 can be slidably installed in the sliding groove 610, thereby realizing the installation of the positioning column 140 in the positioning hole 600, and a blocking block 620 for blocking the sliding groove 610 is provided at the opening position thereof. The blocking block 620 is connected to the opening position of the sliding groove 610 by adhesion, and limits the slider 450 sliding into the sliding groove 610, thereby realizing the sliding installation of the positioning column 140;

[0049] Among them, through the settings of the blocking block 620 and the slider 450, when the blocking block 620 is installed at the opening of the sliding groove 610, the downward movement of the slider 450 can abut against the blocking block 620, so that the slider 450 cannot continue to move downward. At this time, the lower end surface of the push rod 630 will not protrude from the positioning hole 600, thus avoiding its interference with the insertion and extraction of the cleaning cover 110 outside the protective cover 100.

[0050] Working principle: Fix the protective cover 100 outside the lens of the industrial camera 10. Slide the guiding block into the guiding groove 230 from the opening of the guiding groove 230 and slide along the guiding groove 230, so that the cleaning cover 110 can slide along the outer side wall of the protective cover 100. When the cleaning cover 110 slides along the outer side wall of the protective cover 100, its end can abut against the inclined surface 220, so that the cleaning cover 110 can squeeze the inclined surface 220 downward, and the bolt 210 can retract into the placement cavity 420. When the cleaning cover 110 drives the positioning hole 600 to slide to the opening position of the placement cavity 420, the spring 510 can push the bolt 210 upward, so that the bolt 210 can push the push rod 630 to drive the positioning column 140 upward, thus completing the fixed installation of the cleaning cover 110 on the protective cover 100; When the transparent plate 250 needs to be cleaned, rotate the knob 130 so that the sponge pad 310 rotates to wipe the transparent plate 250. After wiping, pressing the positioning column 140 downward can push the push rod 630 downward, so that the push rod 630 can disengage from the positioning hole 600 of the bolt 210 and retract into the placement cavity 420, thus releasing the fixation of the cleaning cover 110, and the cleaning cover 110 can be removed.
