Description
Technical Field
[0001] The utility model belongs to the technical field of automobile air conditioners, and more specifically relates to a clamp structure for automobile air conditioner pipelines. Background Art
[0002] Automobile air conditioning systems need to provide cooling and heating functions to adjust the comfort of the cab. Air conditioning pipes are one of the components of automobile air conditioning systems. They are used to connect the main components of the air conditioning system and ensure the circulation of refrigerant within the system. In order to conveniently, quickly and effectively complete the production line assembly of air conditioning pipes, it is necessary to install a fixing device in the pipe to prevent the pipe from shaking and causing wear during the driving of the car. Existing air conditioning pipe clamps generally consist of two curved metal strips, which are fixed together by bolts or other connecting parts to complete the connection of the air conditioning pipes. This type of structural clamp often requires the use of other tools to assist in the installation operation, and its operation is relatively cumbersome; especially when working in a small space, it is even more inconvenient. Therefore, designing a clamp structure that is simple to operate and suitable for working in a small space has important production practical significance.
[0003] A search revealed patent CN216479337U, which discloses a novel pipe clamp installation structure for automotive air conditioning pipes. This application includes a sheet metal pipe clamp, bushings A, and bushings B. The clamp comprises a pipe sleeve A, a fixing portion, and a pipe sleeve B, which are connected in sequence to form a single unit. The fixing portion has a fixing hole in the center. The pipe sleeves A and B have circular cross-sections and are respectively secured to the bushings A and B in a circular fashion. The integrated double-pipe sleeve structure, combined with the double bushings, provides a stable fixation for the twin aluminum pipes. Utility Model Content

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.
[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] The present invention will be further described below in conjunction with specific embodiments.
[0033] like Figure 1 、 Figure 2 As shown in the figure, this embodiment of a clamp structure for automobile air conditioning pipes includes a detachably connected first body 1 and a second body 2. The first body 1 is used to fit over the connection between two pipes and perform a clamping connection operation; the second body 2 is used to control the expansion and contraction state of the first body 1.
[0034] Specifically, if Figure 3 As shown, the first body 1 includes an annular clamp body 11, and the two ends of the clamp body 11 are respectively formed with a first end 12 and a second end 13. At the same time, an avoidance groove 111 is opened on the clamp body 11 near the second end 13. After the first end 12 passes through the avoidance groove 111, it is arranged crosswise with the second end 13, and the first end 12 can slide in the avoidance groove 111. When there is no external force, the first end 12 and the second end 13 are away from each other; at this time, the clamp body 11 is in a tightened state. When the first end 12 and the second end 13 are subjected to opposite external forces, the first end 12 slides in the sliding groove and approaches the second end 13, so that the clamp body 11 is in an expanded state.
[0035] Preferably, a plurality of weight-reducing grooves 112 are provided along the circumferential direction of the clamp body 11. By providing the weight-reducing grooves 112, on the one hand, the deadweight can be reduced and material costs can be saved; on the other hand, the squeezing and approaching operation of the two ends of the clamp body 11 can be made more labor-saving. At the same time, the first body 1 is made of elastic material, and the second body 2 is made of plastic material. The elastic material and plastic material here are both existing technologies and are not listed here one by one. Specifically in this embodiment, the first body 1 is made of 51CrV4 (high-grade spring steel); the second body 2 is made of PA66 (thermoplastic resin).
[0036] like Figure 4 As shown, the second body 2 has a limiting notch 21, with limiting surfaces 211 formed on either side of the opening of the limiting notch 21. When the two ends of the clamp body 11 are inserted into the limiting notch 21, the limiting surfaces 211 squeeze and limit the ends, respectively, keeping the clamp body 11 in an expanded state. When the second body 2 is removed, the restraining force on the first and second ends 12, 13 is released. Under the elastic force of the clamp body 11, the first and second ends 12, 13 move away from each other, returning to a tightened and locked state.
[0037] To facilitate removal of the second body 2 from the first body 1, a grip portion 22 is provided on the second body 2. Preferably, the grip portion 22 is a through hole. As long as the operator's finger can enter the through hole, the second body 2 can be removed, thereby effectively reducing the operating space requirement.
[0038] Furthermore, at least one of the two limiting surfaces 211 is an inwardly inclined surface. Preferably, the angle of the inclined surface is 5-25°, for example, 10°, 15°, or 20°. In this embodiment, the inclined design of the limiting surface 211 effectively prevents the end of the clamp body 11 from falling out of the limiting notch 21. Furthermore, the limiting surface 211 is connected to a guide surface 212 that is tilted outward to facilitate the insertion of the end of the clamp body 11.
[0039] The clamp structure for automobile air-conditioning pipes of this embodiment has the following operation process: pinch the first end 12 and the second end 13 of the clamp body 11 so that the two are close to each other; then the two ends are clamped into the limiting groove 21, and the two limiting surfaces 211 respectively squeeze and limit the two ends so that the clamp body 11 is in an expanded state; then the clamp body 11 is sleeved on the connection between the two pipes, and the pre-connection between the clamp body 11 and the pipes can be completed by providing adhesive or glue on the inner side of the clamp body 11; then, hold the holding part 22 to pull or rotate, so that the two ends of the clamp body 11 are separated from the opening or both sides of the limiting groove 21; at this time, after the first end 12 and the second end 13 lose the constraint of the limiting groove 21, the two ends move away from each other under the action of the restoring force of the clamp body 11 itself, and the pipe is clamped. Compared with traditional clamps, the clamp structure for automobile air-conditioning pipes in this embodiment can complete the locking operation without the assistance of additional tools. It is not only convenient and quick to operate, but also greatly reduces the requirements for operating space, so it can be used for connection operations in some narrow spaces.
[0040] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
