Description

Technical Field

[0001] The utility model relates to the technical field of industrial camera equipment, in particular to a sealing cover for a camera probe. Background Art

[0002] In the prior art, the sealing cover for the camera probe, especially the sealing cover for the endoscope camera probe, and the front glass of the lens module are all exposed to the external environment, lacking effective protection measures. The lens module structure is relatively fragile, and the sealing cover for the endoscope camera probe often needs to be inserted into a narrow space during actual use. In this case, the front glass of the lens module is easily damaged by friction and collision. Once damaged, the entire sealing cover for the camera probe can only be replaced for maintenance, which not only increases the maintenance cost, but also affects the normal use of the equipment.

[0003] In addition, since the front glass of the lens module is directly exposed to the outside, impurities such as dust and dirt can easily adhere to the surface of the lens module, thereby contaminating the lens module.

[0004] Furthermore, when using the sealing cover for such camera probes to observe the inside of an object with a flowing nature, the flowing object will flow directly to the front of the lens module and stick to the lens module. However, the focal length required for observation is greater than the distance of the fluid close to the lens module, which results in blurred imaging or even no imaging, seriously affecting the observation effect of the flowing fluid.

[0005] In summary, the existing sealing cover for endoscope camera probe has many deficiencies in structural design. Utility Model Content

[0006] In view of this, the utility model proposes a sealing cover for a camera probe to prevent the front glass of a lens module from being exposed to the external environment, thereby effectively protecting the front glass of the lens module.

[0026] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0027] Example 1

[0028] See also Figure 1 The embodiment of the utility model discloses a sealing cover for a camera probe, which is suitable for industrial endoscopes and industrial dental mirrors. The sealing cover 20 is detachably arranged on the front end outer wall of the lens module 10, and at least the front end surface of the sealing cover 20 is a light-transmitting surface.

[0029] Preferably, the sealing cover 20 is a fully transparent structure, with a gap between the front end surface of the sealing cover 20 and the front end surface of the lens module 10, and the rear end inner wall of the sealing cover 20 and the front end outer wall of the lens module 10 are connected by threads or tight plug-in.

[0030] The sealing cover for a camera probe of the embodiment of the utility model can be detachably provided with a sealing cover 20 on the front end outer wall of the lens module 10, so that the front end glass of the lens module 10 can be located inside the sealing cover 20, thereby effectively avoiding direct collision and friction between the front end glass and surrounding objects when the lens module 10 passes through a narrow space, reducing the risk of damage to the front end glass of the lens module 10, and extending the service life of the lens module 10. The inner wall at the rear end of the sealing cover 20 and the front end outer wall of the lens module 10 are connected by threaded connection or tight plug-in connection, which not only ensures the stability of the connection, but also facilitates the disassembly and installation of the sealing cover 20, and is conducive to replacement when the sealing cover 20 is damaged, thereby greatly improving the convenience of use and maintenance efficiency of the sealing cover for the camera probe. At the same time, in view of the gap between the front end face of the sealing cover 20 and the front end face of the lens module 10, when observing the inside of an object with a flowing nature, the flowing object and the front end of the lens are always kept at a distance, and the fluid can be placed in a clear observation position, effectively solving the problem that the fluid is not imaged when it is attached to the front end of the lens, and greatly improving the clarity and accuracy of the imaging.

[0031] Example 2

[0032] like Figure 2 As shown, this embodiment is further improved based on Embodiment 1, and the improvement lies in that: the front end surface of the sealing cover 20 is a beveled surface, and a reflector 30 is fixedly provided on the beveled surface. The reflector 30 can be a reflective coating arranged on the front end surface of the sealing cover 20, which can realize the side shooting of the lens module 10. In specific scenes where space is limited or shooting from a special angle is required, the required image information can be easily obtained, which effectively solves the problem of limited shooting angle of the traditional lens module 10 in complex environments.

[0033] Example 3

[0034] This embodiment is similar to the first embodiment, except that a magnifying glass or a reducing glass is fixedly provided on the front end surface of the sealing cover 20, so as to realize the magnification or reduction of the imaging of the object. The magnifying glass and the reducing glass can not only flexibly adjust the size ratio of the imaging, but also accurately realize a specific imaging effect without changing the original performance of the camera, thus meeting the diversified shooting needs.

[0035] Example 4

[0036] like Figure 3 As shown, this embodiment is further improved based on the embodiment 1, and the improvement lies in that the sealing cover 20 includes a cylinder 21 and a hook body fixed to the front end edge of the cylinder 21, and the rear end of the cylinder 21 is detachably arranged on the front end outer wall of the lens module 10, and part of the measured material in the camera area can be hooked out by means of the hook body, such as rings, ropes and other ring-shaped objects.

[0037] In this embodiment, the hook body includes a long rod 22, a short rod 23 and a hollow ring 24. The hollow ring 24 is located directly in front of the cylinder 21. The front ends of the long rod 22 and the short rod 23 are fixed on a diameter of the rear end surface of the hollow ring 24. The rear end of the long rod 22 is fixed to the edge of the front end surface of the cylinder 21. There is a space between the rear end of the short rod 23 and the front end of the cylinder 21. A magnet 25 is embedded in the hollow ring 24. The magnet 25 can absorb scattered iron items (such as keys and metal buttons) in the camera area to achieve the purpose of taking out specific items, which brings great convenience to the operation.

[0038] In the embodiment of the present utility model, it should be noted that the hook body and the magnet 25 have little effect on the shooting range of the lens module 10 and do not affect the inspection of the internal structure of the object by the lens module 10.

[0039] The technical solution of the utility model is described in detail above in combination with specific embodiments, and the described specific embodiments are used to help understand the concept of the utility model. Derivations and variations made by those skilled in the art based on the specific embodiments of the utility model also fall within the protection scope of the utility model.
