Description

Technical Field

[0001] The utility model relates to the technical field of monitoring camera housings, and specifically relates to a structure of a screw for preventing loosening and detachment of a moving platform of a monitoring camera housing. Background Technique

[0002] The monitoring camera housing is a commonly used protection structure for monitoring cameras at present. The monitoring camera is installed in the housing for protection. An internally movable mounting platform needs to be installed inside the monitoring camera housing. The camera is fixed on the mounting platform and can be moved and adjusted in position along with the mounting platform. At present, the mounting platform and the sliding rod are connected by screws, and the problem of screw loosening is likely to occur during use. After loosening, the monitoring camera will automatically move back and forth when rotating, resulting in changes in the monitoring screen. Content of the Utility Model

[0003] The utility model provides a structure of a screw for preventing loosening and detachment of a moving platform of a monitoring camera housing, which can solve the problem that the locking screws of the internally movable mounting platform in the monitoring camera housing are likely to loosen during use.

[0004] To achieve the above object, the utility model provides the following technical solution: A structure of a screw for preventing loosening and detachment of a moving platform of a monitoring camera housing, including a housing main body. A translatable mounting platform is arranged on the inner bottom surface of the housing main body. A sliding groove is arranged at the bottom of the housing main body. A slidable sliding rod is installed in the sliding groove. The mounting platform is connected to a screw hole on the sliding rod through at least one anti-detachment screw. The anti-detachment screw includes a nut main body and a screw rod arranged inside the nut main body. The screw rod and the nut main body are in anti-rotation fit. A threaded portion is arranged on the outer side of the lower part of the screw rod. A step is arranged at the top of the screw rod. A spring is sleeved on the outer side of the screw rod. The upper end of the spring abuts against the step, and the lower end of the spring abuts against the nut main body.

[0005] Preferably, a plurality of anti-rotation ribs are arranged along the axial direction on the side wall of the screw rod, and the anti-rotation ribs are embedded in grooves on the inner side wall of the nut main body and slide.

[0006] Preferably, a detachable top cover is arranged in the middle of the top of the nut main body, and the size of the top cover is not less than the size of the step.

[0007] Preferably, a tool groove is arranged in the middle of the top of the top cover.

[0008] Preferably, the top cover is threadedly connected to the nut main body.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The structure is simple. By arranging a spring and an axially movable screw rod inside the anti-loosening screw, during the locking process of the screw rod and the sliding rod, the nut body can press the installation platform and maintain the pressed state under the action of the spring, without loosening, thus avoiding the self-movement of the installation platform during use.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] As Figures 1-4 shown, the present utility model provides a structure of a tightening and anti-loosening screw for a moving platform of a monitoring camera housing, including a housing main body 1. On the inner bottom surface of the housing main body 1, a translatable installation platform 2 is provided. At the bottom of the housing main body 1, a sliding groove is provided, and a slidable sliding rod 4 is installed in the sliding groove. The installation platform 2 is connected to a threaded hole on the sliding rod 4 through at least one anti-loosening screw 3. The anti-loosening screw 3 includes a nut body 31 and a screw rod 34 arranged inside the nut body 31. The screw rod 34 and the nut body 31 are in anti-rotation cooperation. A threaded portion 37 is provided on the outer side of the lower part of the screw rod 34, a step 35 is provided at the top of the screw rod 34, and a spring 33 is sleeved on the outer side of the screw rod 34. The upper end of the spring 33 abuts against the step 35, and the lower end of the spring 33 abuts against the nut body 31.

[0017] Specifically, three threaded holes are provided on the sliding rod 4, which can be connected to three anti-loosening screws 3 on the installation platform 2. If in order to improve the installation speed, only one anti-loosening screw 3 can be installed to meet the requirements. When in use, the rotation of the nut body 31 will drive the screw rod 34 to rotate together. At the same time, with the cooperation of the threaded portion 37 of the screw rod 34 and the threaded hole on the sliding rod 4, the screw rod 34 axially moves towards the sliding rod 4. At the same time, by compressing the spring 33, the nut body 31 can always be pressed against the installation platform 2 and is not easy to loosen.

[0018] To prevent the rotation of the screw rod 34, a plurality of anti-rotation ribs 36 are axially arranged on the side wall of the screw rod 34, and the anti-rotation ribs 36 are embedded in the grooves on the inner side wall of the nut body 31 and slide therein.

[0019] To facilitate the installation of the screw rod 34, a detachable top cover 32 is centrally arranged at the top of the nut body 31, and the size of the top cover 32 is not less than that of the step 35. At the same time, a tool groove 38 is centrally arranged at the top of the top cover 32. The tool groove 38 can be a cross groove or a flat groove, which is convenient for using a screwdriver to rotate the nut body 31. The top cover 32 is threadedly connected to the nut body 31, which is convenient for installation.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0021] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0022] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
