Description

Technical Field

[0001] The utility model belongs to the technical field of connecting fittings, and particularly relates to an air-conditioning pipe joint. Background Art

[0002] When an air-conditioning pipe is connected through a pipe joint, an insulating layer is usually wound around the pipe and its joint to reduce heat and cold loss. However, since the pipe joint needs to be electrified, its design usually includes a plug-in part protruding outwards to facilitate the insertion of a plug and achieve power-on.

[0003] The current design is to install a terminal post inside this plug-in part, and the front end of the plug bites with the terminal post to complete the circuit connection. Such a design results in a relatively high protrusion of the plug-in part relative to the surface of the pipe joint. When winding the insulating layer, a large cavity will be formed when transitioning from the circumferential surface of the pipe joint to the plug-in part, thus affecting the heat preservation effect of this part. Content of the Utility Model

[0004] The utility model aims at the above problems existing in the prior art, and provides an air-conditioning pipe joint that can improve the heat preservation effect after winding an insulating tape.

[0005] The utility model can be realized by the following technical solutions:

[0006] A joint body, whose side wall has a protruding sheath, and the sheath has a through hole opened along its axial direction and is communicated with the inner cavity of the joint body through the through hole;

[0007] A terminal head, which is installed in the through hole of the sheath, and the terminal head has a jack and is used for being plugged with an external plug to be electrified. Among them,

[0008] the height of the sheath does not exceed 4 mm, and the height of the terminal head does not exceed the height of the sheath.

[0009] As a further improvement of the utility model, the joint body needs to be wound with an insulating layer to cover the area where the sheath is located. When winding the insulating layer, the insulating layer will break away from the surface of the joint body and extend to the outer end face of the sheath for winding. At this time, the joint body has a first point where the insulating layer just breaks away from its surface, and the sheath has a second point where the insulating layer first contacts its surface. The connection line between the first point and the second point forms an angle α with the height direction of the sheath, and the angle α≥50°.

[0010] As a further improvement of the utility model, the through hole of the sheath has a stepped surface.

[0011] As a further improvement of the utility model, the terminal head is composed of an inserted part and a limiting part connected integrally and is arranged in a T-shaped structure.

[0012] As a further improvement of the present utility model, the insertion part is inserted along the through hole of the sheath, and the limiting part can abut against the step surface.

[0013] As a further improvement of the present utility model, the outer end surface of the limiting part does not exceed the opening position of the outer end surface of the sheath.

[0014] As a further improvement of the present utility model, at least one annular groove is formed on the circumferential surface of the insertion part, and the annular groove is used for installing a sealing ring.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] For the air-conditioning pipe joint of the present application, by adjusting the height of the sheath and the structure of the wiring head, the included angle formed by the connection line of the first point and the second point and the height direction of the sheath can be expanded to ≥50°, thereby greatly reducing the cavity formed after winding the heat-insulating tape at this position, and further achieving the purpose of improving the heat-insulating effect.

[0028] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical methods of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] As Figure 1-7 shown, the present invention provides an air-conditioning pipe joint, including:

[0030] The joint body 100 is provided with a through cavity along the central axis direction, and at the same time, the side wall of the joint body 100 has a convex sheath 110 outward. The sheath 110 has a through hole opened along its axis direction and is communicated with the inner cavity through the through hole;

[0031] The terminal 120 is installed in the through hole of the sheath 110. The terminal 120 has a jack 121 and is used for being plugged with an external plug 200 to be electrified. The outer end face of the terminal 120 does not exceed the outer end face of the sheath 110. Among them,

[0032] the height of the sheath 110 does not exceed 4 mm, and the height of the terminal 120 does not exceed the height of the sheath 110.

[0033] It should be noted that the joint body 100 needs to be wound with a heat-insulating tape to cover the area where the sheath 110 is located. When winding the heat-insulating tape, the heat-insulating tape will break away from the surface of the joint body 100 and extend to the outer end face of the sheath 110 for winding. At this time, the joint body 100 has a first point 101 where the heat-insulating tape just breaks away from its surface, and the sheath 110 has a second point 111 where the heat-insulating tape first contacts its surface. The connection line between the first point 101 and the second point 111 forms an angle α with the height direction of the sheath 110. When the height of the sheath 110 does not exceed 4 mm, the angle α≥50°.

[0034] Among them, the higher the protruding height of the sheath 110, the smaller the angle formed by the connection line between the first point 101 and the second point 111 and the height direction of the sheath 110, and the larger the cavity formed after winding the heat-insulating tape at this position;

[0035] For example, in the commonly used air-conditioning pipe joints at present, since terminal posts (equivalent to the above-mentioned terminal head 120) are installed inside the insertion part, the height of the entire insertion part (equivalent to the sheath 110 and the terminal head 120) is relatively high, and the included angle α formed by the connection line between the first point 101 and the second point 111 and the height direction of the sheath 110 is between 30° and 40°. This results in an overly large cavity formed after winding the thermal insulation tape at this position, affecting the thermal insulation effect of this part;

[0036] In contrast, for the air-conditioning pipe joint of the present application, by adjusting the height of the sheath 110 and the structure of the terminal head 120, the included angle formed by the connection line between the first point 101 and the second point 111 and the height direction of the sheath 110 can be expanded to ≥50°. Thereby, the cavity formed after winding the thermal insulation tape at this position is significantly reduced, and further the purpose of improving the thermal insulation effect is achieved.

[0037] Preferably, there is a step surface 112 in the through hole of the sheath 110.

[0038] Preferably, the terminal head 120 is composed of an insertion part 122 and a limiting part 123 which are integrally connected and is arranged in a T-shaped structure. Among them, the insertion part 122 is inserted along the through hole of the sheath 110, and the setting of the limiting part 123 plays a limiting role through cooperation with the step surface 112 to prevent the terminal head 120 from being inserted excessively.

[0039] Preferably, the outer end surface of the limiting part 123 does not exceed the opening position of the outer end surface of the sheath 110, so as to ensure that after winding the thermal insulation tape, the terminal head 120 will not protrude outward from the opening of the sheath 110, resulting in a bulge of the thermal insulation tape at this position, and improving the thermal insulation effect after winding the thermal insulation tape.

[0040] Preferably, at least one annular groove 1221 is formed on the circumferential surface of the insertion part 122. The annular groove 1221 is used for installing a sealing ring to improve the connection tightness between the terminal head 120 and the sheath 110 and prevent the terminal head 120 from loosening.

[0041] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is the specific implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will also change accordingly.

[0043] In addition, in the present utility model, descriptions such as "first", "second", "one", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0044] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0045] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
