Description

Technical Field

[0001] The utility model relates to the field of signal generating devices, in particular to an analog signal generating device. Background Art

[0002] An analog signal generating device is an electronic device used to generate various types of analog signals, such as sine waves, square waves, sawtooth waves, triangular waves, noise signals, etc. These signals are widely used in fields such as scientific research, engineering testing, education, industrial control, communication, and calibration and testing of audio equipment.

[0003] In the design of traditional signal generators, the focus is often on functionality and performance stability, neglecting portability. This results in the fact that in on-site tests outside the laboratory, teaching demonstrations, or emergency mobile situations, the bulky signal generators are difficult to carry quickly and safely, affecting the flexibility and efficiency of use.

[0004] Therefore, it is necessary to provide a new analog signal generating device to solve the above technical problems. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides an analog signal generating device.

[0006] The analog signal generating device provided by the utility model includes a signal generator body. A protective outer frame and a fixed bracket are fixedly connected to the top of the signal generator body. A connecting rod is rotatably connected to the fixed bracket. A lifting handle is fixedly connected to the outside of the connecting rod at the fixed bracket. The lifting handle is located inside the protective outer frame. A fixing component is arranged inside the connecting rod at the fixed bracket. A limiting member is slidably connected to the fixed bracket, and an elastic member is arranged on the limiting member.

[0007] Further, a semi-circular bracket is fixedly connected inside the fixed bracket. Annular grooves are opened at both ends of the semi-circular bracket. The connecting rod is placed in the annular groove of the semi-circular bracket and can rotate along its side wall.

[0008] A connecting bracket is fixedly connected to one side of the semi-circular bracket. A rectangular through groove is opened on the connecting bracket.

[0009] Further, the fixing component includes two connecting ratchets. The two connecting ratchets are fixedly connected to the outer surface of the connecting rod, and the rotation directions of the two connecting ratchets are opposite.

[0010] Further, the limiting member includes a rectangular sliding rod. The rectangular sliding rod is slidably connected in the rectangular through groove opened on the connecting bracket. A pulling rod is fixedly connected to one end of the rectangular sliding rod. Two connecting ratchet blocks are fixedly connected to the side of the rectangular sliding rod away from the pulling rod.

[0011] Further, the shapes and structures of the two connecting ratchet blocks are adapted to the two connecting ratchets with opposite helix directions.

[0012] Further, the elastic member is a telescopic spring, and the telescopic spring is disposed outside the rectangular sliding rod. The two ends of the telescopic spring are fixedly connected to the outer side wall of the fixed bracket and the side wall of the lifting handle respectively.

[0013] Compared with the related art, the analog signal generating device provided by the present utility model has the following beneficial effects:

[0014] When the lifting handle of the analog signal generating device is in the use state, the user can easily operate the limiting member to disengage from the fixing assembly, thereby canceling the angle locking of the connecting rod and the lifting handle, and allowing the user to adjust the inclination angle of the device according to the actual use scenario or personal preference, improving the flexibility of use.

[0015] When the lifting handle of the analog signal generating device is in the non-use state, it is adjusted to be flush with the signal generator body by the disengagement of the limiting member, reducing the occupied space and facilitating storage and carrying.

[0016] The protective outer frame and the fixed bracket provide physical protection for the signal generator body, reducing the damage to the precision instrument caused by external factors. The fixed bracket provides a support point for the rotation of the connecting rod and serves as the installation basis for the subsequent adjustment assembly. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0025] As Figures 1 to 6 shown, the analog signal generation device provided by the present utility model includes a signal generator body 1, which is responsible for generating the required analog signal. A protective outer frame 2 and a fixed bracket 3 are fixedly connected to the top of the signal generator body 1. A connecting rod 6 is rotatably connected to the fixed bracket 3. A lifting handle 7 is fixedly connected to the outside of the fixed bracket 3. The lifting handle 7 is located inside the protective outer frame 2. A fixing component is arranged inside the fixed bracket 3 for the connecting rod 6. A limiting member is slidably connected to the fixed bracket 3. The limiting member can be separated from the fixing component when the connecting rod 6 rotates and adjusts to a specified angle, and is combined with the fixing component before and after the adjustment of the connecting rod 6, so as to limit the rotation angle of the connecting rod 6. And an elastic member is arranged on the limiting member, and the elastic member provides a reset function when the limiting member moves;

[0026] The protective outer frame 2 and the fixed bracket 3 provide physical protection for the signal generator body 1 and serve as the installation basis for subsequent adjustment components. The protective outer frame can reduce the damage of external factors to precision instruments, and the fixed bracket 3 provides a support point for the rotation of the connecting rod 6;

[0027] The connecting rod 6 is connected to the fixed bracket 3 by rotation. The setting of the lifting handle 7 facilitates the user to manually operate and adjust the angle of the connecting rod 6. The lifting handle 7 is located inside the protective outer frame 2 to ensure operation safety and not affect the appearance neatness at the same time;

[0028] The fixing component is located inside the connecting rod 6 and interacts with the limiting member. The limiting member is slidably connected to the fixed bracket 3 and can be combined with or separated from the fixing component as needed, and the angle of the connecting rod 6 can be freely adjusted within a certain range. When the preset position is reached or fixation is required, the limiting member is tightly combined with the fixing component to limit further rotation;

[0029] The elastic member assembled on the limiting member provides the necessary resilience during the movement of the limiting member, ensuring that it can automatically return to its original position or a predetermined position after release, simplifying the operation process, making the adjustment smoother, and at the same time improving the overall stability and durability of the device.

[0030] Before adjustment, the limiting member and the fixing component are pre - combined to restrict the initial position of the connecting rod 6. During adjustment, the user rotates the connecting rod 6 by pulling the handle 7. When the angle needs to be changed, the limiting member and the fixing component are temporarily separated, allowing free rotation to the target angle. After adjustment, when the specified angle is reached, the limiting member and the fixing component are re - combined. With the assistance of the elastic member, it is automatically locked and maintains the new position, ensuring that the angle of the signal generator remains stable during use.

[0031] Inside the fixed bracket 3, a semi - circular bracket 4 is fixedly connected. At both ends of the semi - circular bracket 4, annular grooves are provided. The connecting rod 6 is placed in the annular groove of the semi - circular bracket 4 and can rotate along its side wall. On one side of the semi - circular bracket 4, a connecting bracket 5 is fixedly connected. A rectangular through - slot is provided on the connecting bracket 5. The fixing component includes two connecting ratchets 8. The two connecting ratchets 8 are fixedly connected to the outer surface of the connecting rod 6, and the rotation directions of the two connecting ratchets 8 are opposite.

[0032] The limiting member includes a rectangular sliding rod 10. The rectangular sliding rod 10 is slidably connected to the rectangular through - slot provided on the connecting bracket 5. At one end of the rectangular sliding rod 10, a lifting rod 9 is fixedly connected. On the side of the rectangular sliding rod 10 away from the lifting rod 9, two connecting ratchet blocks 12 are fixedly connected. The shapes and structures of the two connecting ratchet blocks 12 are adapted to the two connecting ratchets 8 with opposite rotation directions. The elastic member is a telescopic spring 11. The telescopic spring 11 is placed outside the rectangular sliding rod 10, and both ends of the telescopic spring 11 are fixedly connected to the outer side wall of the fixed bracket 3 and the side wall of the lifting handle 7 respectively.

[0033] The semi - circular bracket 4 is not only fixed inside the fixed bracket 3, but also the annular grooves at both ends enable the connecting rod 6 to rotate smoothly on a semi - circular track, thus meeting the multi - angle adjustment requirements, ensuring the smoothness of rotation, and at the same time restricting the movement range of the connecting rod 6.

[0034] The two connecting ratchets 8 are fixed on the outer surface of the connecting rod 6, and their rotation directions are opposite. During the locking process, the angles of both connecting ratchets 8 are restricted. Through their special tooth - shaped structures, they engage with the connecting ratchet blocks 12 to ensure the stability after angle adjustment.

[0035] The rectangular sliding rod 10 is slidably connected to the rectangular through - slot of the connecting bracket 5 and can move smoothly along a specific path. By pulling the lifting rod 9, the user can control the movement of the sliding rod and the connecting ratchet blocks 12, making the connecting ratchet blocks 12 engage with or disengage from the connecting ratchets 8, thereby realizing the limiting function.

[0036] The telescopic spring 11 is arranged outside the rectangular sliding rod 10 and is fixed between the outer side wall of the fixed bracket 3 and the side wall of the lifting handle 7. After the lifting rod 9 is released, it uses its elastic force to push the sliding rod back to the initial position, ensuring the automatic return function of the device and improving the convenience and reliability of use.

[0037] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
