Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaring device technology, specifically to a flaring device for air conditioning connecting pipes. Background Technology
[0002] An air conditioning pipe flaring device is a device used to enlarge the port of an air conditioning pipe in order to install nuts and connect indoor and outdoor units. It usually includes flaring tools and related accessories, such as flaring pressers and pipe clamps.
[0003] In existing technologies, when flaring the connecting pipe of an air conditioner, a flaring head is usually inserted inside the connecting pipe. By rotating and inserting the flaring head, the connecting pipe is flared. However, in actual use, the pipe needs to be fixed before flaring. In existing technologies, the flaring device is usually set separately from the fixing device. In use, the air conditioner connecting pipe needs to be fixed with the fixing device first, and then the flaring device needs to be connected with the fixing device before the hole position can be positioned and calibrated. Flaring can only be performed after calibration and fixation, which makes the operation inconvenient. Therefore, it is necessary to improve the air conditioner connecting pipe flaring device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an air conditioning connecting pipe flaring device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an air conditioning connecting pipe flaring device, including a fixing clamp block, a positioning hole is provided inside the fixing clamp block, a pipe clamping mechanism is provided on the front and right sides of the fixing clamp block, and a flaring mechanism is provided on the top of the fixing clamp block.
[0006] Preferably, the pipe clamping mechanism includes a rotating clamping block, which is rotatably mounted on the front of a fixed clamping block. A docking gripping block is fixedly mounted on the right side of both the fixed clamping block and the rotating clamping block. An insertion rod is fixedly mounted on the right side of the docking gripping block. A limit sleeve is provided on the outside of the insertion rod. A limit sliding strip is fixedly mounted on the back of the fixed clamping block, which facilitates the fixed clamping of the air conditioning connecting pipe by the pipe clamping mechanism.
[0007] Preferably, the limiting sleeve has a binding hole inside, and the insertion rod is slidably installed inside the binding hole inside the limiting sleeve, which facilitates the limiting of the fixed clamping block and the rotating clamping block.
[0008] Preferably, there are two limiting slide bars, and the two limiting slide bars are symmetrically distributed on the back of the fixed clamping block, which improves the stability of the sliding bracket.
[0009] Preferably, the flaring mechanism includes a sliding bracket, which is slidably mounted on the outside of the limiting slide bar. An internally threaded post is fixedly mounted on the end of the sliding bracket away from the limiting slide bar. A turning threaded rod is installed on the internal thread of the internally threaded post. A flaring head is fixedly mounted on the bottom of the turning threaded rod. A fixing plate is fixedly mounted on the inner back side of the sliding bracket. A positioning pin is slidably mounted inside the fixing plate. A pull buckle is fixedly mounted on the top of the positioning pin. A spring is fixedly mounted on the inner top side of the positioning pin, which facilitates the positioning and flaring of the air conditioning connecting pipe through the flaring mechanism.
[0010] Preferably, the spring is disposed outside the positioning post, and the end of the spring away from the positioning post is fixedly installed to the top of the fixing plate, so as to facilitate the normal insertion of the positioning post into the positioning hole.
[0011] Preferably, a groove is provided at the corresponding position of the sliding bracket and the limiting slide bar, and the limiting slide bar is slidably installed inside the groove provided inside the sliding bracket, so as to facilitate normal movement of the sliding bracket to adjust the position of the enlarged hole.
[0012] Compared with the prior art, the present invention provides an air conditioning connecting pipe flaring device, which has the following beneficial effects:
[0013] 1. This air conditioning connection pipe flaring device, through its flaring mechanism, allows the flaring head to rotate downwards by rotating the threaded rod during use, thus flaring the air conditioning connection pipe. The sliding bracket outside the limiting slide bar allows for direct adjustment and calibration without docking. Once the positioning pin is inserted into the corresponding positioning hole, the positioning calibration is locked. Furthermore, the combination of the pipe clamping mechanism and the flaring mechanism allows for quick flaring by holding the pipe with one hand while rotating the threaded rod with the other after fixing the air conditioning connection pipe. It is also portable, space-saving, and avoids the cumbersome operations of fixing, docking, positioning calibration, and post-calibration fixing, improving the portability and ease of use of the flaring device.
[0014] 2. This air conditioning connection pipe flaring device, through its clamping mechanism, uses different sized clamping slots inside the fixed clamping block and the rotating clamping block to clamp and fix the air conditioning connection pipe during use. It can be directly flared by holding the two closed mating gripping blocks by hand, or the limiting sleeve can be put on the outside of the plug rod for later processing, thus realizing the function of fixing the flared air conditioning connection pipe.

A spring 38 is fixedly mounted on the inner top side of the positioning pin 36, which facilitates the positioning and flaring of the air conditioning connecting pipe through the flaring mechanism 3.
[0026] Furthermore, the spring 38 is disposed outside the positioning pin 36, and the end of the spring 38 away from the positioning pin 36 is fixedly installed on the top of the fixing plate 35, so that the positioning pin 36 can be properly inserted into the positioning hole 4.
[0027] Furthermore, grooves are provided at corresponding positions of the sliding bracket 31 and the limiting slide 25, and the limiting slide 25 is slidably installed inside the grooves provided inside the sliding bracket 31, which facilitates normal movement of the sliding bracket 31 to adjust the position of the enlarged hole.
[0028] Example 2:
[0029] Please see Figure 4 Furthermore, in conjunction with Embodiment 1, the clamping mechanism 2 includes a rotating clamping block 21, which is rotatably mounted on the front of the fixed clamping block 1. Both the fixed clamping block 1 and the rotating clamping block 21 have docking gripping blocks 22 fixedly mounted on their right sides.
