Abstract
Description
Technical Field
[0001] This utility model relates to the field of water rockets, specifically a mechanism for a water rocket launch base. Background Technology
[0002] A water rocket is a science education and entertainment model that uses water and compressed air as a power source. Its launch pad is an important component of the water rocket system, primarily used to support the rocket body and control the launch angle.
[0003] Existing technologies include some launch bases with angle adjustment functions. For example, multiple positioning holes are set on the bracket, and the angle is changed by changing the connection between the launch tube and different positioning holes. However, this adjustment method is step-by-step and jump-like, and cannot achieve stepless fine adjustment. It is difficult to accurately set to a specific angle, and the structure is relatively complex. The adjustment process is cumbersome, requiring disassembly and reinstallation of components, making operation inconvenient.
[0004] In summary, existing water rocket launch bases suffer from drawbacks such as inconvenient and inaccurate angle adjustment, lack of horizontal calibration function, and insufficient safety.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The support arm has a second mounting hole, and the ear portion has an arc-shaped groove. A fastening screw passes through the second mounting hole and the arc-shaped groove. The tilt angle of the launch platform is locked or unlocked by tightening or loosening the fastening screw.
[0008] As a further embodiment of this utility model: the support arm is also provided with a third mounting hole and a fourth mounting hole, the first mounting hole, the third mounting hole and / or the fourth mounting hole are located at different heights, and are used to cooperate with the mounting column to change the initial tilt angle of the launch platform.
[0009] As a further embodiment of this invention, the launch platform is equipped with a level.
[0010] This utility model has the following beneficial effects:
[0011] (1) Through the hinged engagement between the mounting column and the first mounting hole and the sliding locking structure of the fastening screw and the arc-shaped groove, the operator can continuously and smoothly adjust the launch platform to any angle.
[0012] (2) When adjusting the angle, only one fastening screw needs to be tightened or loosened, which eliminates the tedious steps of disassembly, changing the hole position and reinstallation in the traditional method. Attached Figure Description

[0023] Example 1:
[0024] like Figures 1 to 2 As shown, the present invention provides a water rocket launch base mechanism, which mainly includes a bracket 1, a launch platform 2, and fastening screws 3.
[0025] The support 1 is typically made of metal or high-strength plastic, and its bottom has a base 11 for stable support. In this embodiment, the base 11 has a rectangular frame structure to increase stability. Extending upwards from the base 11, a pair of symmetrical support arms 12 are provided on both sides. The support arms 12 have four mounting holes, from top to bottom: a first mounting hole 13, a second mounting hole 14, a third mounting hole 15, and a fourth mounting hole 16. Among them, the first mounting hole 13 is used to realize a rotatable connection with the launch platform 2.
[0026] The launch platform 2 is used to carry and fix water rockets (not shown in the figure), and mainly includes a platform section 21 for placing the rockets. The platform section 21 is connected to a pair of lugs 22, which correspond to a pair of support arms 12 of the bracket 1. Each lug 22 has an outwardly protruding mounting post 23 on its inner side. By inserting the mounting post 23 into the first mounting hole 13 on the support arm 12, the launch platform 2 is connected to the bracket 1, so that the launch platform 2 can rotate relative to the bracket 1 with its mounting post 23 as the axis, thereby adjusting the launch angle.
[0027] An arc-shaped groove 24 is also provided on each ear 22. The position of the second mounting hole 14 on the bracket 1 corresponds to the position of the arc-shaped groove 24 when the launch platform 2 is at a specific angle. During assembly, the fastening screw 3 passes through the second mounting hole 14 on the support arm 12 and the arc-shaped groove 24 on the ear 22 in sequence, and is tightened at the end with the fastening screw 3.
[0028] Furthermore, the third mounting hole 15 on the support arm 12 provides an additional fixing point. For example, when a larger fixed launch angle is required, the mounting post 23 of the launch platform 2 can be removed from the first mounting hole 13 and inserted into the lower third mounting hole 15, and then connected to the ear 22. This provides a different initial angle reference, which, combined with the arc-shaped slide 24 for fine-tuning, expands the adjustable range of the launch angle.
[0029] The adjustment process is as follows:
[0030] When adjusting the launch angle, first loosen the nut on the fastening screw 3. At this time, the launch platform 2 can rotate freely around the mounting column 23. The operator can lift or lower the free end of the launch platform 2, and the arc-shaped slide groove 24 on the ear 22 will slide relative to the fastening screw 3. Observe the scale 26 on the ear 22, rotate it to the required angle (e.g., 30° or 45°), and then tighten the nut on the fastening screw 3 again to firmly lock the launch platform 2 and the bracket 1 at that angle, thus completing the stepless fine adjustment of the launch angle.
[0031] Example 2:
[0032] The scheme of this embodiment is largely the same as that of Embodiment 1, except that, in order to meet the requirements for vertical launch of the water rocket, a level 25 is also installed on the platform section 21 of the launch platform 2 to observe whether the bubble of the level 25 is centered, so as to ensure that the platform section 21 itself is in a horizontal state. The water rocket is then launched vertically in this state.
[0033] To further enhance safety, a safety mechanism 27 is also provided at the rear of the launch platform 2. This safety mechanism 27 includes a sliding latch. During the inflation preparation process of the water rocket, the latch can be slid down below the launch trigger to prevent accidental activation and avoid accidental launch; once ready, the latch can be slid open to allow for normal launch operation.
[0034] Working principle:
[0035] In use, first level the entire launch base using the level 25. Then, install the water rocket on the launch platform 2 and connect the air pump. Before launch, place the locking pin of the safety mechanism 27 in the safe position to prevent accidental triggering. After inflation, based on the target distance and referring to the scale 26, complete the angle setting by loosening the fastening screw 3, rotating the launch platform 2 to the predetermined angle, and then tightening the fastening screw 3 again. Finally, slide open the safety mechanism 27 to prepare for launch. This invention is simple to operate, precise to adjust, safe, and reliable, making it ideal for teaching and outdoor activities.
[0036] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
