Description

Technical Field

[0001] The utility model belongs to the technical field of mouse prevention, in particular to a novel mouse-blocking board device. Background Art

[0002] At present, key areas such as substations and machine rooms mainly rely on traditional wooden or plastic rat guards to prevent rodent invasion. However, this traditional rat guard has many problems in actual use. First, patrol personnel need to frequently cross or manually lift the rat guard, which is inconvenient and inefficient. Second, in emergency situations such as fires, traditional rat guards may become obstacles to escape or rescue, increasing the difficulty of rescue. Although new types of rat guards exist on the market, their promotion is limited due to factors such as complex structure, high cost, and difficult maintenance.

[0003] Therefore, it is necessary to develop a new type of rat guard device that can effectively prevent rats and facilitate the passage of people, so as to overcome the defects of traditional rat guards and improve the practicality and efficiency of rat prevention measures. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a novel mouse guard device.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel mouse-blocking board device, comprising a frame, a U-shaped track, a spring roller blind, a pull plate, a fixed pulley, a connecting rope, a pull rope, and two limit mechanisms;

[0006] A cavity is provided in the frame, and the bottom end of the frame is fixedly connected to the U-shaped track. A spring roller blind is slidably provided in the U-shaped track, and the upper end of the spring roller blind is fixedly connected to the pull plate. Limit grooves are provided at both ends of the pull plate, and each limit groove is used in conjunction with a corresponding limit mechanism. The two limit mechanisms are symmetrically arranged and both are arranged in the cavity. The two limit mechanisms are both fixedly connected to the pull rope, and the pull rope is arranged outside the frame. The pull plate is fixedly connected to one end of the connecting rope, and the other end of the connecting rope is attached to a fixed pulley and extends outside the frame. The fixed pulley is rotatably connected to the inner wall of the cavity.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. Easy to operate: By pulling the pull rope and the connecting rope, the user can easily open and close the spring roller blinds without complicated operation process, which improves the convenience of use.

[0009] 2. Automatic limit function: The limit mechanism in this device is cleverly designed, using the wedge surface of the limit block and the rebound effect of the spring to achieve automatic limit of the pull plate. This ensures that the spring roller shutter can be firmly fixed in the required position when closed, preventing accidental opening.

[0010] 3. Compact and stable structure: The overall structure of the device is compact, and the connection relationship between the components is clear and definite, which is not only easy to manufacture and maintain, but also ensures the stability and reliability of the device.

[0011] 4. High efficiency: By using the spring and pulley system, the device can quickly retract and fix the spring roller blind, improve work efficiency, and enable users to control the opening and closing status of the channel more quickly.

[0012] 5. Wide range of applications: This new type of mouse barrier device is suitable for various occasions where small animals such as mice need to be prevented from entering, such as warehouses, factories, homes, etc., and has a wide range of application prospects.

[0013] In summary, the new mouse guard device provides users with a convenient and practical solution through its convenient operation, automatic limiting function, compact and stable structure and high efficiency, effectively preventing the invasion of small animals.

[0016] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] This embodiment describes a novel mouse-blocking device, including a frame 1, a U-shaped track 2, a spring roller blind 3, a pull plate 4, a fixed pulley 5, a connecting rope 6, a pull rope 7, and two limiting mechanisms;

[0018] A cavity is provided in the frame 1, and the bottom end of the frame 1 is fixedly connected to the U-shaped track 2. A spring roller blind 3 is slidably provided in the U-shaped track 2, and the upper end of the spring roller blind 3 is fixedly connected to the pull plate 4. Limiting grooves are provided at both ends of the pull plate 4, and each limiting groove is used in conjunction with a corresponding limiting mechanism. The two limiting mechanisms are symmetrically arranged and both are arranged in the cavity. The two limiting mechanisms are fixedly connected to the pull rope 7, and the pull rope 7 is arranged outside the frame 1. The pull plate 4 is fixedly connected to one end of the connecting rope 6, and the other end of the connecting rope 6 is attached to the fixed pulley 5 and extends outside the frame 1. The fixed pulley 5 is rotatably connected to the inner wall of the cavity.

[0019] Each of the limiting mechanisms comprises a second fixed pulley 8, a second connecting rope 9, a third fixed pulley 10, a fixing plate 11, a limiting block 12, a sliding rod 13 and a spring 14;

[0020] The inner wall of the frame 1 is provided with a sliding hole 1, which is communicated with the cavity in the frame 1, the fixed pulley 2 8 and the fixed pulley 3 10 are respectively rotatably connected to the inner wall of the cavity, one end of the connecting rope 2 9 is fixedly connected to the pull rope 7, and the other end of the connecting rope 2 9 is attached to the fixed pulley 2 8 and the fixed pulley 3 10 in sequence and is fixedly connected to one end of the sliding rod 13, the fixed plate 11 is fixedly connected to the inner wall of the cavity, the fixed plate 11 is provided with a sliding hole 2, the other end of the sliding rod 13 slides through the sliding hole 2 and is fixedly connected to the limit block 12, the spring 14 is sleeved on the sliding rod 13, one end of the spring 14 is fixedly connected to the fixed plate 11, and the other end of the spring 14 is fixedly connected to the limit block 12, the limit block 12 is slidably arranged in the sliding hole 1, and one end of the limit block 12 is a wedge-shaped surface and is used in conjunction with the corresponding limit groove.

[0021] When it is necessary to open the spring rolling curtain 3, the user will pull the pull rope 7 located outside the frame 1, and the pulling of the pull rope 7 is transmitted to each limiting mechanism through the connecting rope 2 9. The connecting rope 2 9 is attached to the fixed pulley 2 8 and the fixed pulley 3 10 in turn, so that the sliding rod 13 slides into the cavity of the frame 1 under the action of tension, and the sliding of the sliding rod 13 drives the limiting block 12 to move, so that the limiting block 12 gradually moves away from the limiting groove on the pull plate 4. Since the limiting block 12 no longer restricts the pull plate 4, the spring rolling curtain 3 is retracted downward along the U-shaped track 2 under the action of its own spring, thereby opening the channel; when it is necessary to close the spring rolling curtain 3, the user will pull one end of the connecting rope 6, and the connecting rope 6 The other end is fixedly connected to the pull plate 4, so pulling the connecting rope 6 will cause the pull plate 4 to rise. As the pull plate 4 rises, the limit groove thereon gradually aligns with the position of the limit block 12. Since one end of the limit block 12 is designed as a wedge-shaped surface, when the pull plate 4 contacts the wedge surface, the limit block 12 can temporarily move into the cavity to avoid the rising path of the pull plate 4. When the pull plate 4 continues to rise and the limit groove thereon is completely aligned with the limit block 12, due to the rebound effect of the spring 14, the limit block 12 will quickly enter the limit groove, thereby fixing the position of the pull plate 4. After the pull plate 4 is fixed, the spring roller blind 3 fixedly connected thereto is also fixed in the desired position, thereby achieving a closing effect.

[0022] Through the above working principle, the novel mouse guard device realizes the convenient opening and closing operation of the spring roller blind 3 and the effective limit function. It has an ingenious design, a compact structure, and a clear connection relationship between the components, making the device easy to manufacture and maintain. At the same time, the use of the spring and pulley system improves the operating efficiency, allowing the user to easily control the opening and closing state of the spring roller blind 3.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms of assembly without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
