Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a monitoring camera device. Background Art

[0002] A surveillance camera is a device used to monitor and record video, usually consisting of a lens, image sensor, processor, and transmission medium. Its working principle is mainly to convert light signals into electrical signals through photosensitive devices and image processing devices, and transmit images and sounds to the monitoring center or storage device through transmission media (such as wired network, wireless network, etc.).

[0003] At present, the zoom structure of surveillance cameras generally adopts a single-sided drive to drive the lens to move back and forth. Since the driving force of the single-sided drive lens is not uniform and the support for the lens is limited, after long-term use, the lens moves back and forth repeatedly, which will cause the lens to tilt and shift easily, resulting in unclear monitoring images. Utility Model Content

[0004] The utility model aims to provide a monitoring camera device. The utility model can wrap the sliding member through the guide member, and provide the sliding member with 360-degree support and limit when sliding, so as to avoid the sliding member driving the movable lens to slide forward and backward and produce deviation and tilt, ensure the stability of the movable lens, and extend the service life of the monitoring camera device.

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0065] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0066] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0067] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0068] Reference Figure 1-7 A monitoring camera device 100 includes: a monitoring body 101, a fixing sleeve 102, a fixed lens 103, a guide member 104, a driving member 105, a sliding member 106, a movable lens 107, and a rotation-stopping member 108; the monitoring body 101 has an installation space; the fixing sleeve 102 is fixed in the installation space, and the fixing sleeve 102 is composed of two half sleeves, so that the lens and other parts can be installed in the fixing sleeve 102; the fixed lens 103 is fixed in the fixing sleeve 102, and a fixing groove 102a for fixing the fixed lens 103 is provided on the inner wall of the fixing sleeve 102, and the fixed lens 103 is embedded in the fixing groove 102a.

[0069] The guide member 104 is rotatably arranged in the fixed sleeve 102 through a bearing. The guide member 104 is provided with a circular hole 104a, and a guide groove 104b is provided on the inner wall of the circular hole 104a, and the guide groove 104b is spiral; the driving member 105 is fixed in the fixed sleeve 102, and the driving member 105 adopts a stepping motor; the sliding member 106 is in the shape of a circular ring sleeve, and an embedding strip 109 is integrally formed on the outer wall of the sliding member 106, and the embedding strip 109 is constructed as a spiral strip, which is the same as the trajectory of the guide groove 104b and is embedded in the guide groove 104b; the movable lens 107 is fixed in the sliding member 106; the stop member 108 passes through the sliding member 106 along the axis of the sliding member 106, and the two ends of the stop member 108 are fixed on the fixed sleeve 102, and the stop member 108 has a pair of stop members 108, which are located at the upper and lower ends of the sliding member 106.

[0070] When zooming, the driving member 105 starts to drive the guide member 104 to rotate, and the guide member 104 drives the sliding member 106 to rotate. However, due to the anti-rotation effect of the anti-rotation member 108, the sliding member 106 cannot rotate. Under the action of the guide groove 104b and the embedded strip 109, the rotation of the guide member 104 is converted into the forward and backward movement of the sliding member 106, driving the fixed lens 103 to move forward and backward to achieve zooming.

[0071] Since the guide member 104 is wrapped around the sliding member 106, it supports and limits the sliding member 106 360 degrees, making it difficult for the sliding member 106 to deviate and tilt when sliding, thereby making the zoom of the monitoring camera device 100 stable. Even if the monitoring camera device 100 is zoomed for a long time and multiple times, the movable lens 107 can be stable and not deviate during the process of moving back and forth, thereby ensuring the clarity of the monitoring.

[0072] The fixed lens 103 includes: a first fixed mirror 103a, a second fixed mirror 103b, a third fixed mirror 103c, and a fourth fixed mirror 103d; the first fixed mirror 103a is fixed at the front end of the fixed sleeve 102; the second fixed mirror 103b is located at one side of the first fixed mirror 103a; the third fixed mirror 103c is located at a side of the second fixed mirror 103b away from the first fixed mirror 103a; the third fixed mirror 103c is located at a side of the second fixed mirror 103b away from the first fixed mirror 103a; the fourth fixed mirror 103d is located at a side of the third fixed mirror 103c away from the second fixed mirror 103b; and the movable lens 107 is located between the second fixed mirror 103b and the third fixed mirror 103c.

[0073] The sliding member 106 is composed of a sleeve body 106a and a cover body 106b. The sleeve body 106a is a circular ring sleeve. A portion of the end surface of the sleeve body 106a is concave to form a placement groove 106c for placing the movable lens 107. An internal thread is provided on the inner wall of the sleeve body 106a at one end close to the placement groove 106c. The cover body 106b is in a circular ring shape. An external thread is provided on the outer wall of the cover body 106b, which is threadedly connected to the internal thread. The movable lens 107 is clamped between the cover body 106b and the sleeve body 106a. The sleeve body 106a and the cover body 106b have rubber rings on the surface of the movable lens 107 to buffer the pressure and prevent the movable lens 107 from being crushed by the sleeve body 106a and the cover body 106b.

[0074] When installing the movable lens 107 on the sliding member 106 , the movable lens 107 is first placed in the placement groove 106 c , and then the cover 106 b is screwed onto the sleeve 106 a to clamp the movable lens 107 and fix the movable lens 107 .

[0075] By clamping the bottom surface of the placement groove 106c and the end surface of the cover body 106b, it is ensured that the movable lens 107 is perpendicular to the axis of the sleeve body 106a after installation, reducing the risk of the movable lens 107 being offset during installation.

[0076] A rotating shaft 110 is transmission-connected to the output end of the driving member 105, and a gear 111 is provided at one end of the rotating shaft 110; a tooth groove 104c is provided on the outer wall of the guide member 104, and the tooth groove 104c surrounds the outer wall of the guide member 104 with the axis of the guide member 104 and meshes with the gear 111, so that the rotation of the gear 111 drives the guide member 104 to rotate.

[0077] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
