Description

Technical Field

[0001] This utility model relates to the field of window screw transmission technology, specifically to a steering gear with a profile pad structure. Background Technology

[0002] Top-hung windows, also known as awning windows, are windows with hinges located at the top and can open inwards or outwards. Furthermore, based on the opening direction, top-hung windows can be divided into inward-opening and outward-opening types. They are suitable for office areas, providing more workspace and better natural light.

[0003] Since high-hung windows are often installed at a high position, an automatic opening and closing device is usually installed on the window to avoid manual climbing to open the window. However, the automatic opening and closing device requires a power source, and it is difficult to manually open and close the window when there is a power outage. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a steering gear with a profile pad structure that combines linear telescopic and rotational motion to achieve complex spatial trajectories. It not only solves the fundamental engineering problem of height matching but also significantly improves the installation accuracy, structural rigidity, and operational stability of the entire system through precise machining and ingenious connection methods, while also considering modular design and ease of maintenance.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A steering gear with a profile pad structure includes a fixed support frame, on which a telescopic assembly is mounted. A steering transmission assembly is located on the side of the telescopic assembly. The telescopic assembly includes a telescopic rod, and the steering transmission assembly includes a steering gear. An aluminum pad is located at the lower end of the steering gear. A profile pad is positioned between the aluminum pad and the steering gear, and the profile pad contains several cross-head self-tapping screws that penetrate the aluminum pad for secure connection. A transmission rod is located between the steering gear and the telescopic rod.

[0006] Preferably, the steering gear has a transmission rocker arm at the front end, and the transmission rocker arm and the steering gear have a hinge joint.

[0007] Due to the space required for the transmission rocker arm operation, the profile shim is cut to length according to the required installation height of the steering gear. The size of the profile shim can be adjusted arbitrarily according to requirements.

[0008] Preferably, the lower end face of the profile pad is provided with a plurality of cross countersunk bolts that are threadedly connected and fixed to the profile pad, and the steering gear is provided with a plurality of cross pan head bolts that are threadedly connected and fixed to the profile pad.

[0009] Preferably, the fixed support frame includes a pair of fixed seats, and a plurality of support rods are provided between the two fixed seats.

[0010] Preferably, a telescopic rotating seat is provided between the support rod and the telescopic rod, and a movable end connecting seat is provided at the other end of the telescopic rod.

[0011] This invention can achieve the following effects: This utility model provides a steering gear with a profile pad structure. Compared with existing technologies, it combines linear telescopic motion and rotational motion, enabling the realization of complex spatial trajectories. It not only solves the fundamental engineering problem of height matching, but also significantly improves the installation accuracy, structural rigidity, and operational stability of the entire system through precise machining and ingenious connection methods, while also taking into account modular design and ease of later maintenance. It has the following significant advantages: (1) Height adjustment and flexibility: Core function: The primary function of profile spacers is to elevate components. In mechanical design, it is often necessary to raise a component (such as the steering gear in this case) to a specific height to match the axis of other transmission components (such as drive rods and telescopic rods), or to make room for components below.

[0012] Standardization and customization: Profile blocks can be manufactured into a series of products with standard heights, or different heights can be easily customized as needed, greatly improving design flexibility without modifying the entire support frame.

[0013] (2) High installation accuracy: Integrated machining: The upper and lower mounting surfaces of the profile pad are precisely machined in one clamping process, ensuring extremely high parallelism and flatness.

[0014] Eliminating cumulative errors: Compared to using multiple thin shims stacked together, using a single profile shim block can eliminate the gaps and cumulative errors between shims, ensuring that the installation posture of the steering gear (12) is very accurate. This is crucial for ensuring the alignment of the transmission rod (7) and the telescopic rod (10), and can effectively reduce vibration and wear.

[0015] (3) The structure is stable and has a strong load-bearing capacity: Rigid connection: The profile pad and aluminum pad are "combined" by four self-tapping screws, and then the whole is firmly fixed to the foundation by two countersunk bolts, forming a very stable "pier"-like structure.

[0016] Stress Dispersion: The aluminum pad increases the contact area with the base platform, which can effectively disperse the vibration and torque generated during the operation of the steering gear and protect the base platform. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: Figure 1-4 As shown, a steering gear with a profile pad structure includes a fixed support frame 1, which includes a pair of fixed seats 6, with two support rods 9 between the two fixed seats 6. A telescopic assembly 5 is provided on the fixed support frame 1, which includes a telescopic rod 10. A telescopic rotating seat 8 is provided between the support rods 9 and the telescopic rod 10, and a movable end connecting seat 11 is provided at the other end of the telescopic rod 10. A steering transmission assembly 2 is provided on the side of the telescopic assembly 5, which includes a steering gear 12. A transmission rocker arm 4 is provided at the front end of the steering gear 12, and a hinge joint 3 is provided between the transmission rocker arm 4 and the steering gear 12. An aluminum pad 14 is provided at the lower end of the steering gear 12. A profile pad 13 is provided between the aluminum pad 14 and the steering gear 12. Four cross-head self-tapping screws 15 are provided inside the profile pad 13 for fixed connection through the aluminum pad 14. Two cross-head countersunk bolts 17 are provided on the lower end face of the profile pad 13 for threaded connection and fixation. Four cross-head bolts 16 are provided on the steering gear 12 for threaded connection and fixation with the profile pad 13. A transmission rod 7 is provided between the steering gear 12 and the telescopic rod 10.

[0024] Working principle: Power input: The steering gear 12 rotates through the rocker arm 4.

[0025] Power transmission: The output shaft of the steering gear 12 transmits rotational power to the telescopic rod 10 via the transmission rod 7.

[0026] Compound motion execution: Under the constraint of the telescopic rotary seat 8, the telescopic rod 10 converts a single rotational input into a compound output motion: Telescopic movement: The rotation of the transmission rod 7 is achieved through an internal screw mechanism. The telescopic rod itself is a screw, and there is a nut inside the rotating seat, which drives the telescopic rod 10 to extend or retract in a straight line along the support rod 9.

[0027] Rotational motion: Simultaneously, the telescopic rod 10 itself rotates around its own axis under the support of the bearing of the telescopic rotating seat 8.

[0028] End effect: The combined motion of the telescopic rod 10 is ultimately transmitted to the end effector through the movable end connector 11 to realize specific functions such as grasping, pushing, positioning, and turning.

[0029] In summary, this profile pad structure steering gear combines linear telescopic motion and rotational motion, enabling it to achieve complex spatial trajectories. It not only solves the fundamental engineering problem of height matching but also significantly improves the installation accuracy, structural rigidity, and operational stability of the entire system through precise machining and ingenious connection methods, while also taking into account modular design and ease of later maintenance.
