Technical Field
[0001] This utility model relates to the technical field of water pipe fixing devices, and in particular to a fixing device for cooling water pipes of laser equipment. Background Technology
[0002] In the field of laser processing equipment, the cooling system is a core component ensuring stable equipment operation. Currently, the industry commonly uses threaded connections to fix the cooling water pipes to the equipment interface. For example, threaded joints made of metal or engineering plastics are tightened to create a seal. This structure relies on the mechanical engagement of the threads to form a sealing interface, and has advantages such as convenient installation and low initial cost.
[0003] However, long-term practice has shown that such threaded connection devices have significant defects: First, under conditions such as high-frequency vibration of equipment, periodic thermal expansion and contraction, and repeated disassembly and assembly, the thread contact surface is prone to wear, leading to stripping and sealing failure. Therefore, the entire threaded connection device needs to be replaced, resulting in increased costs. To address these issues, we propose a laser equipment cooling water pipe fixing device. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a laser equipment cooling water pipe fixing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A laser equipment cooling water pipe fixing device includes a first water pipe, a connecting assembly, and a second water pipe. The first water pipe and the second water pipe are connected by the connecting assembly. A second flange is fixedly connected to the left side of the first water pipe. A fixing sleeve is sleeved on the right side surface of the connecting assembly, and a first fixing ring is inserted into the inner wall of the fixing sleeve. The first fixing ring is fixedly connected to the inner wall of the fixing sleeve.
[0007] Preferably, a third water pipe is fixedly connected to the left side of the second water pipe, and the third water pipe is inserted inside the first fixing ring. The inner ring of the first fixing ring has an internal thread, and the outer ring of the third water pipe has an external thread. The first fixing ring and the third water pipe form a threaded fixed connection.
[0008] Preferably, the inner ring of the fixing sleeve has an internal thread, and the outer ring on the right side of the connecting assembly has an external thread, and the fixing sleeve and the connecting assembly are threadedly connected.
[0009] Preferably, a second fixing ring is inserted inside the connecting component, and a third fixing ring is sleeved on the outer ring of the second fixing ring. The inner wall of the connecting component has an internal thread, and the outer ring of the third fixing ring has an external thread that matches the internal thread of the inner wall of the connecting component.
[0010] Preferably, a circular groove is provided at the center of the second fixing ring, and a sealing rubber ball is inserted inside the circular groove. A spring is fixedly connected to the right side of the sealing rubber ball, and a first fixing ring is fixedly connected to the right side of the second fixing ring. The right side of the spring is fixedly connected to the inner wall of the first fixing cover.
[0011] Preferably, two sets of fixing brackets are symmetrically connected to the left side of the second fixing ring, and a funnel is fixedly connected to the left side of the fixing brackets.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. By rotating the fixed sleeve, the severely worn first fixed ring can be quickly replaced, thus solving the problem of stripping of the first fixed ring after long-term use. By replacing the first fixed ring, the cost of replacing the entire device can be reduced, greatly increasing the practicality of the device.
[0014] 2. In this device, the sealing rubber ball is pushed by a spring to achieve the sealing effect of the second fixing ring, thereby solving the problem that dust and impurities enter the device through the water outlet when the device is not in use. The funnel can increase the impact force of the water flow, which makes it easier to move the sealing rubber ball and open the notch of the fixing cover to facilitate the discharge of water.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 A laser equipment cooling water pipe fixing device includes a first water pipe 1, a connecting component 2, and a second water pipe 3. The first water pipe 1 and the second water pipe 3 are connected by the connecting component 2. A second flange 5 is fixedly connected to the left side of the first water pipe 1. A fixing sleeve 4 is sleeved on the right side surface of the connecting component 2, and a first fixing ring 6 is inserted into the inner wall of the fixing sleeve 4. The first fixing ring 6 is fixedly connected to the inner wall of the fixing sleeve 4.
[0022] Furthermore, refer to Figure 2 It can be seen that the third water pipe 7 is fixedly connected to the left side of the second water pipe 3, and the third water pipe 7 is inserted into the first fixing ring 6. The inner ring of the first fixing ring 6 has an internal thread, and the outer ring of the third water pipe 7 has an external thread. The first fixing ring 6 and the third water pipe 7 form a threaded fixed connection.
[0023] Furthermore, refer to Figure 2 It can be seen that the inner ring of the fixing sleeve 4 has an internal thread, and the outer ring on the right side of the connecting component 2 has an external thread. The fixing sleeve 4 and the connecting component 2 are threadedly connected. During use, the first fixing ring 6 can be quickly replaced by using the internal and external threads of the connecting component 2 and the fixing sleeve 4 together.
[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the connecting component 2 has a second fixing ring 11 inserted inside, and the outer ring of the second fixing ring 11 is fitted with a third fixing ring 12. The inner wall of the connecting component 2 has an internal thread, and the outer ring of the third fixing ring 12 has an external thread that matches the internal thread of the inner wall of the connecting component 2.
[0025] Furthermore, refer to Figure 4 It can be seen that a circular groove is provided at the center of the second fixing ring 11, and a sealing rubber ball 13 is inserted inside the circular groove. A groove is provided on the left side of the sealing rubber ball 13, which facilitates better concentration of water flow during use. A spring 14 is fixedly connected to the right side of the sealing rubber ball 13, and a first fixing ring 6 is fixedly connected to the right side of the second fixing ring 11. The right side of the spring 14 is fixedly connected to the inner wall of the first fixing cover 8.
[0026] Furthermore, refer to Figure 4It can be seen that two sets of fixing brackets 10 are symmetrically connected to the left side of the second fixing ring 11, and a funnel 9 is fixedly connected to the left side of the fixing bracket 10. The diameter of the left side of the funnel 9 is adapted to the diameter of the first water pipe 1, which facilitates the contact to achieve a seal and prevents water leakage. During use, the funnel 9 reduces the cross-sectional area of the outlet, thereby increasing the impact force of the water flow and facilitating the concentration of water flow to contact the sealing rubber ball 13, thus facilitating the movement of the sealing rubber ball 13 to the right and facilitating drainage.
[0027] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the first water pipe 1 is fixedly connected to the outlet of the equipment. During installation, the second flange 5 needs to be aligned with the first flange at the outlet. After alignment, the two flanges are fixed. After installation, the third water pipe 7 is inserted into the first fixing ring 6 and rotated to achieve a fixed connection, which facilitates the fixing of the second water pipe 3.
[0028] After prolonged use, repeated friction between the first fixing ring 6 and the third water pipe 7 causes wear on the inner thread of the first fixing ring 6, resulting in stripping. At this time, the operator rotates the fixing sleeve 4 to remove the first fixing ring 6 from the connecting assembly 2. After that, a new set of fixing sleeves 4 and the first fixing ring 6 are installed, which solves the problem of stripping. The operation is completed. The above is the complete working principle of this utility model.
