Description

Technical Field

[0001] The utility model relates to a field, and particularly relates to a connector based on an ultrasonic therapeutic apparatus. Background Art

[0002] The ultrasonic therapeutic apparatus includes a device body and a handle, and the handle is connected to the device body through a connecting plug. Usually, the ultrasonic therapeutic apparatus plug contains an ultrasonic circuit, an inlet passage and a return passage for circulating cooling water. The plug connectors of the two cooling water pipes and the ultrasonic plug are integrated into one plug. The plug connectors of the two cooling water pipes of the integrated plug are female heads, and the ultrasonic therapeutic apparatus has mating male heads. In a relatively small plug size, it is necessary to achieve electrical and water isolation and ensure no water leakage after repeated plugging and unplugging for a long time, which results in an overly complex structure of the integrated plug. After multiple pluggings and unpluggings, a small amount of water will seep out, affecting the safety of the device. The main reason for water seepage is that after the integrated plug has been plugged and unplugged for a long time, the locking valve of the circulating water path will be slightly damaged, resulting in water seepage and overflow.

[0003] Since the plug is of an integrated structure, when the locking valve is damaged, the entire connecting pipeline needs to be replaced, bringing a relatively high cost to the user unit. The complex structure of the integrated plug will make the integrated plug work unstably.

[0004] Therefore, in order to effectively solve: 1. The complex structure of the integrated plug of the ultrasonic therapeutic apparatus and the high replacement cost; 2. The defect that the integrated plug is prone to water seepage, the utility model proposes a new solution. Summary of the Utility Model

[0036] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0037] As Figures 1 to 6 shown, a connector based on an ultrasonic therapeutic apparatus includes: a connecting sleeve 1 with a hollow structure, a fixed head 2 connected to the cooling circulation system of the ultrasonic therapeutic apparatus, and a plug connector 4 connected to the cooling circulation system of the ultrasonic therapeutic apparatus handle; the connecting sleeve 1, the fixed head 2, and the plug connector 4 all have a hollow structure, and this hollow structure is used for transmitting the flow of the coolant in the cooling circulation system. The main component of the coolant is water.

[0038] The first connection end 11 at one end of the connecting sleeve 1 and the fixed head 2 are detachably connected. Specifically, the fixed head 2 and the connecting sleeve 1 are threadedly connected, which is convenient for installation and disassembly; a first sealing ring 3 is provided between the first connection end 11 and the fixed head 2 for sealing. The material of the sealing ring can be a sealing ring made of ordinary rubber material.

[0039] The central through hole of the second connection end 12 at the other end of the connecting sleeve 1 is a conical structure, and the large diameter end of the conical structure faces outward, and the small diameter end faces the center of the connecting sleeve 1; the conical structure is mainly used for mutual engagement to achieve fixation and sealing.

[0040] One end of the socket 4 is connected to the cooling circulation system, and the outer surface of the other end is provided with a conical surface; the end of the other end of the socket 4 is a card slot 41 with a "Z"-shaped ring structure, and a second sealing ring 43 is also assembled at the end; the thickness of the second sealing ring 43 gradually thins from the center to the edge; the purpose of the "Z"-shaped structure of the card slot 41 is: if the circumferential pressure at the conical surface is too large, it is very difficult to pull out the socket 4 from the connecting sleeve 1. At this time, due to the structural design similar to a platform of the second sealing ring 43, the second sealing ring 43 will directly separate from the socket 4 to reduce the pulling resistance.

[0041] On the outer surface of the socket 4, in the direction from the small-diameter end to the large-diameter end of the conical surface, there are successively arranged: a second sealing ring 43, a third sealing ring 44 made of water-swellable rubber material, and a fourth sealing ring 45; the third sealing ring 44 is installed on the card slot 41 close to the second sealing ring 43. The expansion rate of the water-swellable rubber can be selected with a low expansion coefficient.

[0042] In order to both reduce the taper pressure between the connecting sleeve 1 and the socket 4 and at the same time utilize the taper pressure to connect the connecting sleeve 1 and the socket 4 together, multiple taper rings 42 with the same taper as the conical structure are provided on the conical surface; specifically, the number of taper rings 42 is two, and the fourth sealing ring 45 is arranged between the two taper rings 42.

[0043] In order to enable the socket 4 and the taper ring 42 to have a stable contact pressure, a pressing structure for pressing the socket 4 into the conical structure is also provided on the socket 4. The pressing structure can be a clamp containing a spring structure, or as Figure 7 shown, one end of the socket 4 is provided with multiple through first mounting holes 51, and two first mounting holes 51 are selected in this scheme; one end of the connecting sleeve 1 is provided with multiple through second mounting holes 52, and two second mounting holes 52 are selected in this scheme; the first mounting holes 51 and the second mounting holes 52 are all isolated from each other from the cooling circulation pipeline; the first mounting holes 51 and the second mounting holes 52 are detachably connected by a pin 6. After the socket 4 is inserted into the connecting sleeve 1, keep the first mounting holes 51 and the second mounting holes 52 aligned, and then pass the pin 6 through the first mounting holes 51 and the second mounting holes 52.

[0044] As Figure 5 shown, Figure 6It is a full sectional view. The installation grooves of the third sealing ring 44 and the fourth sealing ring 45 are both flat on the side facing the clamping groove 41, and the cross-section is close to a "Z" - shaped structure. If it is a three - dimensional view, the sides of the installation grooves of the third sealing ring 44 and the fourth sealing ring 45 facing the clamping groove 41 are flush with the axis of the plug - connector 4; that is: there are no recessed obstacles in the installation grooves on the side facing the small - diameter end of the plug - connector 4. When the plug - connector 4 is pulled out from the connecting sleeve 1, the third sealing ring 44 and the fourth sealing ring 45 can be separated from the plug - connector 4, and it is not difficult to pull out the plug - connector 4 due to excessive internal pressure.

[0045] The advantage of such a design is that: in the case of water leakage, the water - swelling gasket will expand towards the surroundings on the "Z" - shaped platform to play a sealing role; when it is necessary to pull out the plug - connector 4, the platform will not hinder the pulling out of the plug - connector 4 due to the expansion of the sealing plug.

[0046] Working principle: Both ends of the connecting sleeve 1 in the present utility model are female - head structures, and the plugs of the handle and on the ultrasonic therapy instrument body are male - heads. The advantages of the male - head are: simple structure, the components on the male - head are all gaskets, convenient to replace, and low cost; using water - absorbing and expanding rubber for sealing is beneficial to sealing and plugging. At the same time, combined with the conical structure design, it can not only achieve rapid sealing but also plugging; in the present utility model, the second sealing ring 43 and the third sealing ring 44 cooperate with each other. If the second sealing ring 43 leaks water, the third sealing ring 44 absorbs water and expands to increase the expansion pressure on the second sealing ring 43, further assisting the second sealing ring 43 in sealing, and the third sealing ring 44 itself can also independently achieve expansion sealing.

[0047] For the connection structure of this application on the ultrasonic therapy instrument, two are required, one for the cold water inlet of the thermal cycle and the other for the hot water outlet of the thermal cycle. After integrating the two plug - connectors 4 and the ultrasonic current of the ultrasonic therapy instrument into an integrated plug, compared with the previous integrated plug with an embedded female - head, this plug has a very high usage and sales.

[0048] In this solution, the taper ring 42 can also be set to an intermittent taper structure. The intermittent design is mainly to avoid the influence on the pulling - out effect if there is air pressure between multiple taper rings 42 when the plug - connector 4 is pulled out, and the intermittent structure can keep the internal and external air pressures the same.
