AI Technical Summary
The existing pneumatic support rod has only one hinge point at the bracket connection, which makes the bracket easy to rotate but difficult to position, and the center of gravity is unbalanced, resulting in poor overall effect.
A pneumatic support rod is designed, in which two gas springs are arranged between the upper bracket and the lower bracket. The gas springs are arranged in parallel and connected by a connecting rod to form two hinge points to fix the bracket, and the center of gravity is arranged in the center.
The bracket is stably positioned and installed, the center of gravity is centered, the overall function is perfect, and the use effect is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machinery, and more particularly to a pneumatic support rod. Background Art
[0002] A pneumatic strut, also known as a gas spring, typically consists of a cylinder and a push rod that extends axially relative to the cylinder. During installation, it is hinged to a bracket at each end. However, due to the single hinge point, the bracket rotates freely, making it difficult to position. Furthermore, the center of gravity of a gas spring with a bracket is biased toward the cylinder end, resulting in an imbalance and poor overall performance. Consequently, the present utility model provides a pneumatic strut. Utility Model Content
[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a pneumatic support rod.
[0004] In order to solve the above technical problems, the purpose of the present invention is achieved as follows: the pneumatic support rod involved in the present invention includes an upper bracket and a lower bracket, and a first gas spring arranged on the left and a second gas spring arranged on the right are provided between the upper bracket and the lower bracket. The second gas spring is arranged parallel to the first gas spring, and the push rod end of the first gas spring is hinged on the upper bracket and the cylinder end is hinged on the lower bracket. The cylinder end of the second gas spring is hinged on the upper bracket and the push rod end is hinged on the lower bracket.
[0005] The utility model is further configured to include a connecting rod with one end hinged to the cylinder of the first gas spring and the other end hinged to the cylinder of the second gas spring.
[0006] The utility model is further configured as follows: the connecting rod is arranged in parallel with the upper bracket and the lower bracket.
[0007] In summary, the present invention has the following beneficial effects:
[0008] 1. There are two hinge points at the connection with the bracket, which prevents it from rotating freely relative to the bracket and is easy to position and install.
[0009] 2. Use two gas springs arranged in opposite directions to keep the center of gravity in the middle. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0011] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0013] Example 1
[0014] See also Figure 1 As shown, the pneumatic support rod involved in this embodiment includes an upper bracket 1 and a lower bracket 2, and a first gas spring 3 arranged on the left and a second gas spring 4 arranged on the right are provided between the upper bracket 1 and the lower bracket 2. The second gas spring 4 is arranged parallel to the first gas spring 3, and the push rod end of the first gas spring 3 is hinged on the upper bracket 1 and the cylinder end is hinged on the lower bracket 2. The cylinder end of the second gas spring 4 is hinged on the upper bracket 1 and the push rod end is hinged on the lower bracket 2.
[0015] In this embodiment, the upper bracket 1 is hinged to one end of the first gas spring 3 and the second gas spring 4, respectively, so that they cannot rotate freely. The lower bracket 2 is hinged to the other end of the first gas spring 3 and the second gas spring 4, respectively, so that they cannot rotate freely.
[0016] Example 2
[0017] See also Figure 1 As shown, the pneumatic support rod involved in this embodiment is further configured to include a connecting rod 5 with one end hinged to the cylinder body of the first gas spring and the other end hinged to the cylinder body of the second gas spring on the basis of Example 1, and the connecting rod 5 is arranged parallel to the upper bracket 1 and the lower bracket 2.
[0018] In this embodiment, the connecting rod 5 is provided to serve as an auxiliary connection.
[0019] The pneumatic support rod of the utility model has two hinge points arranged at the connection with the bracket, so it does not rotate arbitrarily relative to the bracket and is easy to position and install; and two gas springs arranged in opposite directions are used to center the center of gravity, so that the overall function is complete and the practicality is strong.
[0020] Unless otherwise specified, in the present invention, if there are terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicating orientation or positional relationship, they are based on the orientation or positional relationship actually shown and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing orientation or positional relationship in the present invention are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, they can combine the embodiments and understand the specific meanings of the above terms according to specific circumstances.
[0021] Unless otherwise specified or limited, the terms "disposed," "connected," and "connected" in this utility model should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0022] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort.
