Description

Technical Field

[0001] This utility model relates to the field of installation tooling technology for air conditioning components of rail transit vehicles, and in particular to an air conditioning hose clamping device. Background Technology

[0002] During the production and processing of the air conditioning system hose connection joint for high-speed trains, it is necessary to crimp the metal pipe fitting into the hose to achieve the connection between the hose and the metal pipe fitting, and then crimp the fitting to fix it.

[0003] The original method of fixing hoses was push-type crimping. The pusher was controlled by a handle to move the pressure rod, thereby moving the metal pipe fitting. The metal pipe fitting and hose were then crimped together. During the push-type process, after multiple fixings, the device fixing the hose was prone to deformation and wear. The deformation of the device caused the crimping deformation. Moreover, the assembly required two people to work together, which easily led to poor crimping of the pipe fitting, thus affecting the hose's sealing performance and completion efficiency. Secondly, if the force was uneven when pushing the pusher by hand during the assembly of the crimping, it was also easy to cause poor crimping between the hose and the metal pipe fitting, thus affecting the airtightness of the pipeline. In addition, this crimping process required a lot of manpower and physical strength, increasing the amount of material loss. The original push-type crimping method was prone to personnel injury during manual push-type crimping, and had certain defects and shortcomings.

[0004] Therefore, in view of the above problems, it is necessary for this utility model to provide an air conditioning hose clamping device that is simple in structure, easy to operate, and has good connection sealing. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] See Figure 1 As shown;

[0029] A utility model discloses an air conditioning hose clamping device, comprising:

[0030] Base plate 1, with a fixed base 2 fixedly connected to the base plate 1;

[0031] The propulsion component includes a screw 3 that is helically driven by a fixed base 2, and a propulsion plate 8 disposed on the upper part of the screw 3 and rotatably connected to the screw 3. One end of the propulsion plate 8 is fixedly connected to a carrier 9 for supporting a metal pipe joint. Limiting protrusions 6 are provided on both sides of the propulsion plate 8. Limiting wheels 7 that roll in contact with the limiting protrusions 6 are installed on both sides of the top of the fixed base 2, so that the propulsion plate 8 is held on the upper part of the screw 3 and drives the carrier 9 to move back and forth parallel to the screw 3. The setting of the limiting protrusions 6 and the limiting wheels 7 can realize the guiding and limiting functions when the propulsion plate 8 moves. When the screw 3 rotates and controls the propulsion plate 8 to move, the limiting protrusions 6 on both sides of the propulsion plate 8 are adapted to the corresponding limiting wheels 7 to realize the limiting function of the propulsion plate 8.

[0032] The device also includes a fixing component 10 fixed to one end of the base plate 1. The fixing component 10 has a protective frame 1001. The protective frame 1001 has a positioning area that can be sleeved on the outside of the hose. A clamp that can extend and clamp the hose to keep the hose coaxial with the metal pipe joint is installed in the positioning area.

[0033] The clamp includes a lower fixing block 1003 and an upper fixing block 1004 that can extend and retract vertically;

[0034] A support rod 1002 is fixedly connected to the inner wall of the protective frame 1001. A lower fixing block 1003 with a V-shaped structure is fixedly connected to the top of the support rod 1002. The lower fixing block 1003 is used to support and place the hose part. The lower fixing block 1003 and the carrier 9 are on the same horizontal plane, so that the hose and the metal pipe joint can be tightly connected after docking.

[0035] A support 1006 is fixedly connected to the top of the protective frame 1001. A telescopic rod 1005 is slidably connected to the support 1006 and the protective frame 1001. An upper fixing block 1004 is fixed to the lower end of the telescopic rod 1005. Rotating arms 1007 are rotatably connected to both sides of the support 1006. A lower pressing handle 1008 is rotatably connected to the two rotating arms 1007. Two driving arms 1009 are integrally formed on one side of the lower pressing handle 1008. The side of the two driving arms 1009 away from the lower pressing handle 1008 is rotatably connected to the telescopic rod 1005. In this structure, when the telescopic rod 1005 moves downward, it can drive the upper fixing block 1004 to move downward. The upper fixing block 1004 and the lower fixing block 1003 cooperate to clamp the hose part, and then connect the hose and the metal pipe joint.

[0036] The rotating arm 1007, the lower pressure handle 1008, and the drive arm 1009 in this structure can be used to control the extension and retraction of the telescopic rod 1005. In use, the hose part is placed on the lower fixed block 1003, and the lower pressure handle 1008 is rotated to make the drive arm 1009 rotate. At this time, the rotating arm 1007 rotates, and the drive arm 1009 controls the telescopic rod 1005 to move down, thereby realizing the movement control of the upper fixed block 1004 and clamping the hose part on the lower fixed block 1003.

[0037] In the preferred embodiment, vertical plates 5 are fixedly connected to both ends of the push plate 8. The vertical plates 5 are rotatably connected to the screw 3. When the screw 3 rotates, it can drive the push plate 8 and the carrier 9 to move, connecting the metal pipe joints and hoses. It should be noted that the base plate 1 is the bottom support part of the device. The fixed seat 2 is provided with screw holes. The screw 3 is threaded into the screw holes of the fixed seat 2 and can move telescopically when rotating. By rotatably connecting two vertical plates 5 to the screw 3 and fixing the push plate 8 to the top of the two vertical plates 5, when the screw 3 rotates... The vertical plate 5 and the push plate 8 can be moved. Since the vertical plate 5 is rotatably connected to the screw 3, the vertical plate 5 and the push plate 8 will not rotate when the screw 3 rotates. By fixing a carrier 9 on one side of the push plate 8, the carrier 9 is used to load the metal pipe fitting. When the screw 3 rotates, it can drive the push plate 8 and the carrier 9 to move, so that the metal pipe fitting moves closer to the hose and is embedded into the hose, realizing the crimping and forming of the ferrule. This method is convenient, can ensure the tightness of the crimping, and has a good effect.

[0038] like Figure 1 As shown, a handwheel 4 is fixedly connected to one end of the screw 3. The handwheel 4 can control the rotation of the screw 3, thereby enabling the extension and retraction of the push plate 8 and the carrier 9.

[0039] In the above technical solution, the air conditioning hose clamping device provided by this utility model has the following advantages:

[0040] This utility model designs an air conditioning hose clamp crimping device. A fixed base 2 is fixed on a base plate 1, and a screw 3 is threadedly connected to the fixed base 2. When the screw 3 rotates, the push plate 8 moves along the limit wheel 7, driving the carrier 9 to move. This causes the metal pipe joint on the carrier 9 to move closer to the hose, and the hose is fixed to the fixed component 10, thus achieving a tight connection between the hose and the metal pipe joint. The metal pipe joint and the hose form the clamping part, realizing the assembly and docking of the clamp. This forming method ensures the tightness of the clamp crimping and prevents air leakage. Furthermore, this method is easy to operate; simply turning the handwheel controls the movement of the push plate and the metal pipe joint, offering convenience and saving labor costs. This utility model is easy to use and can quickly perform clamp crimping.

[0041] In addition, by installing a fixing component 10 on one side of the base plate 1, the fixing component 10 can fix the hose part, thereby achieving the connection between the hose and the metal pipe joint. The fixing component 10 is easy to use. Simply control the rotation of the pressing handle to control the telescopic rod to move down, so that the upper and lower fixing blocks come together, thereby achieving the clamping of the hose part.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
