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

[0025] The following will Figures 1-6 further explain this embodiment in detail.

[0026] Please refer to Figures 1-6 , an industrial camera lens structure in this embodiment includes a lens barrel 1. A lens body 2 is provided inside the lens barrel 1. A lens cap 3 is provided at the end of the lens barrel 1. Arc-shaped card slots 4 are oppositely provided on the surface of the lens barrel 1. A groove body 5 corresponding to the arc-shaped card slots 4 is provided inside the lens cap 3. A card block 6 that can be telescopic and can be inserted into the arc-shaped card slots 4 is provided inside the groove body 5. A driving assembly for driving the card block 6 to be inserted into the arc-shaped card slots 4 is provided inside the groove body 5. A sliding column 7 with one end extending out of the groove body 5 and used for driving the card block 6 to disengage from the arc-shaped card slots 4 is provided on the card block 6. A control assembly for driving the sliding column 7 to slide is provided on the lens cap 3.

[0027] In this embodiment, through the settings of the lens barrel 1, the lens body 2 and the lens cap 3, the lens body 2 is installed inside the lens barrel 1, and the lens cap 3 is detachably connected to the lens barrel 1 for protecting the lens body 2, so as to prevent dust from adhering to the lens of the industrial camera lens when the industrial camera lens is not in use, which affects the use effect of the industrial camera lens.

[0028] In this embodiment, through the settings of the arc-shaped card slot 4, the slot body 5, the card block 6 and the driving component, the arc-shaped card slot 4 is opened on the outer wall of the lens barrel 1 near the lens of the lens body 2. When the lens body 2 needs to be fixed in the lens barrel 1 for protection, the card block 6 is retracted into the slot body 5, and then the lens cap 3 is buckled outside the lens barrel 1 so that the inner wall of the lens cap 3 fits with the outer wall of the lens barrel 1. At the same time, the slot body 5 is aligned with the arc-shaped card slot 4, and then the card block 6 is driven by the driving component to be snapped into the arc-shaped card slot 4, and the fixing of the lens cap 3 on the lens barrel 1 can be completed.

[0029] In this embodiment, through the settings of the sliding column 7 and the control component, one end of the sliding column 7 is fixedly connected to the central part of the card block 6, and the other end extends out of the outer wall of the lens cap 3 through the slot body 5. The penetrating part between the sliding column 7 and the lens cap 3 is slidably connected. When the lens cap 3 needs to be removed, the sliding column 7 is driven to slide through the control component, and the sliding of the sliding column 7 can drive the card block 6 to disengage from the arc-shaped card slot 4. After the card block 6 disengages from the arc-shaped card slot 4, the lens cap 3 can be directly removed.

[0030] Please refer to Figures 1-6 , in this embodiment, the driving component includes columns 100 that are oppositely arranged on the top wall of the slot body 5 and one end of which extends out of the slot body 5. The columns 100 are arranged in the same direction as the sliding column 7. An installation cavity 101 with an opening facing the slot body 5 is provided in the column 100. A sliding rod 102 is provided in the installation cavity 101. A hollow cylinder 103 that can slide along the sliding rod 102 and the bottom end of which is connected to the card block 6 is provided on the sliding rod 102. A spring 104 for pushing the card block 6 into the arc-shaped card slot 4 is provided in the installation cavity 101. One end of the spring 104 is connected to the top wall of the installation cavity 101, and the other end is connected to the top end of the hollow cylinder 103.

[0031] In this embodiment, through the arrangement of the upright column 100, the installation cavity 101, the sliding rod 102 and the hollow cylinder 103, the upright column 100 and the sliding column 7 are arranged parallel and vertically on both sides of the groove body 5. The installation cavity 101 inside it is arranged along the extending direction of the sliding column 7. The sliding rod 102 is fixedly connected to the center of the installation cavity 101. The bottom end of the hollow cylinder 103 is fixedly connected to the clamping block 6. By sliding the hollow cylinder 103 on the sliding rod 102, the clamping block 6 can be driven to extend out of the groove body 5 or retract into the groove body 5. When the hollow cylinder 103 completely slides into the installation cavity 101, the clamping block 6 can be driven to completely retract into the groove body 5. At this time, the lens cap 3 can be directly buckled on the lens barrel 1, so that the clamping block 6 does not affect the sleeving of the lens cap 3 on the lens barrel 1.

[0032] In this embodiment, through the arrangement of the spring 104, one end of the spring 104 is fixedly connected to the top wall of the installation cavity 101, and the other end is fixedly connected to the top end of the hollow cylinder 103. When the lens cap 3 is fixed on the lens barrel 1, the spring 104 can push the hollow cylinder 103 to slide on the sliding rod 102, thereby driving the clamping block 6 connected to the hollow cylinder 103 to extend out of the groove body 5 until it is completely clamped into the arc-shaped clamping groove 4. At the same time, under the action of the spring 104, the clamping block 6 is clamped tightly with the arc-shaped clamping groove 4, thereby completing the fixation of the lens cap 3 on the lens barrel 1.

[0033] It should be noted that, in order to realize the expansion and contraction of the clamping block 6 along the radial direction of the lens cap 3 in the groove body 5, there is a certain gap between the two ends of the clamping block 6 and the end wall of the groove body 5. At the same time, there are also certain gaps between the side wall of the hollow cylinder 103 and the installation cavity 101 and between the sliding rod 102 and the hollow cylinder 103. Thus, the expansion and contraction movement of the clamping block 6 along the radial direction of the lens cap 3 in the groove body 5 is satisfied.

[0034] Please refer to Figures 1-6 , in this embodiment, a ring body 200 is arranged on the outer side wall of the lens cap 3 and extends axially outward. A cavity 201 is formed between the ring body 200 and the lens cap 3. A limiting frame 202 is arranged in the cavity 201. The control assembly includes a connecting rod 203 arranged on the sliding column 7. A push rod 204 is arranged on the connecting rod 203, and one end of the push rod 204 penetrates through the ring body 200 and extends into the limiting frame 202. A block 205 that can slide and is used to drive the push rod 204 to move up and down is arranged in the limiting frame 202.

[0035] In this embodiment, through the arrangement of the ring body 200, the cavity 201, the limiting frame 202, the connecting rod 203, the push rod 204 and the block 205, the limiting frame 202 is fixedly connected to the center of the cavity 201. The connecting rod 203 is fixedly connected to the sliding column 7, the push rod 204 is fixedly connected to the connecting rod 203, the push rod 204 is slidably connected to the part between the ring body 200 and the limiting frame 202 that it penetrates through, and the block 205 is slidably connected to the limiting frame 202. By driving the block 205 to move, the two push rods 204 are driven to move. The push rod 204 drives the connecting rod 203 to move, and the connecting rod 203 can drive the sliding column 7 to slide. The sliding of the sliding column 7 can drive the clamping block 6 to compress the spring 104 through the hollow cylinder 103, so that the hollow cylinder 103 slides on the sliding rod 102 and retracts into the installation cavity 101, thereby driving the clamping block 6 to retract into the groove body 5, so that the lens cover 3 can be conveniently buckled on the lens barrel 1 or removed from the lens barrel 1.

[0036] Please refer to Figures 1-6 , in this embodiment, on both sides of the block 205, there are respectively provided abutting low planes 206 for the bottom ends of the corresponding push rods 204 to abut against, on both sides of the block 205, there are provided guiding inclined planes 207 connected to the abutting low planes 206 and used for driving the push rods 204 to move upward, and on both sides of the block 205, there are provided abutting high planes 208 abutting against the bottom ends of the push rods 204.

[0037] In this embodiment, through the arrangement of the abutting low planes 206, the guiding inclined planes 207 and the abutting high planes 208, the bottom of the push rod 204 is set to be arc-shaped, so that the push rod 204 is more stable when abutting against the abutting low planes 206, the guiding inclined planes 207 and the abutting high planes 208. When the lens cover 3 is fixed to the lens barrel 1, the bottom end of the push rod 204 is located on the abutting low plane 206. At this time, the clamping block 6 is clamped in the arc-shaped clamping groove 4; when it is necessary to remove the lens cover 3, the sliding block 205 is moved towards the push rod 204, thereby driving the bottom end of the push rod 204 to slide along the guiding inclined plane 207 towards the abutting high plane 208, so as to drive the push rod 204 to move. The push rod 204 drives the connecting rod 203 to move, and further the connecting rod 203 drives the sliding column 7 to slide. When the push rod 204 slides out of the guiding inclined plane 207 to the abutting high plane 208, the sliding column 7 drives the clamping block 6 to disengage from the arc-shaped clamping groove 4 and retract into the groove body 5, and the lens cover 3 can be removed.

[0038] Please refer to Figures 1-6 , in this embodiment, on the ring body 200, there is a circular plate 209 threadedly connected to the ring body 200 for blocking the cavity 201 and the limiting frame 202. A moving groove 210 is formed on the circular plate 209, and on the block 205, there is a dial rod 211 extending out of the moving groove 210 for pushing the block 205 to slide.

[0039] In this embodiment, by setting the circular plate 209, the movable groove 210 and the lever 211, the circular plate 209 and the ring body 200 are threadedly connected to facilitate the installation of the circular plate 209 and the components in the cavity 201. The circular plate 209 can block the limit frame 202 but does not affect the sliding of the block 205. The lever 211 is fixedly connected to the block 205, and the lever 211 is slidably connected to the movable groove 210. The lever 211 can drive the block 205 to slide, and the block 205 drives the push rod 204 to move, thereby controlling the card block 6 to be clamped in the arc card groove 4, or to be disengaged from the arc card groove 4 and retracted into the groove body 5. The user only needs to turn the lever 211 to better complete the fixing and removal of the lens cover 3 and the lens barrel 1, and the operation is simple.

[0040] In this embodiment, the movement of the lever 211 in the movable groove 210 allows the bottom end of the push rod 204 to be located just in contact with the low plane 206 or the high plane 208 when the lever 211 completely slides from one side to the other side. At the same time, under the action of the spring 104, the push rod 204 can be squeezed against the block 205, so that the block 205 can move under the action of external force.

[0041] See also Figures 1-6 In this embodiment, positioning blocks 300 are symmetrically arranged on the surface of the lens barrel 1 , and a slot 301 matching with the positioning blocks 300 is opened on the lens cover 3 .

[0042] In this embodiment, by setting the positioning block 300 and the slot 301, the positioning block 300 is fixedly connected to the outer wall of the lens barrel 1, and the slot 301 is slidably connected to the positioning block 300. When the lens cover 3 is buckled on the lens barrel 1, it can slide on the positioning block 300 through the slot 301 so that the lens cover 3 is buckled on the lens barrel 1. When the lens cover 3 slides on the positioning block 300 through the slot 301 and is buckled on the lens barrel 1, the groove body 5 and the arc-shaped slot 4 can be aligned, so that the block 6 can be accurately inserted into the arc-shaped slot 4, thereby completing the fixation of the lens cover 3 on the lens barrel 1.

[0043] Working principle: When the industrial camera lens structure is in use, the lever 211 is pushed to drive the card block 6 to retract into the groove body 5, so that the lens cover 3 can be directly buckled on the lens barrel 1, and then the lens cover 3 is buckled on the lens barrel 1 by sliding on the positioning block 300 through the slot 301, and the lever 211 is pushed again to drive the card block 6 to be stuck in the arc-shaped card groove 4, and the lens cover 3 can be fixed. When the lens cover 3 needs to be removed, the lever 211 is pushed to drive the card block 6 to disengage from the arc-shaped card groove 4 and retract into the groove body 5, and the lens cover 3 can be directly removed.

[0044] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
