Abstract
The utility model provides a connecting structure for a quick coupling, which comprises a quick coupling, a connecting pipe assembly and an outdoor unit valve body. A female coupling of the quick coupling is connected with the connecting pipe assembly. A male coupling of the quick coupling is in threaded connection with the outdoor unit valve body which is provided with a valve body thread connecting portion. Locking clamp teeth are arranged below the valve body thread connecting portion, and a clamp groove matched with the locking clamp teeth is arranged on the end face of the male coupling. The connecting structure for the quick coupling can prevent the male coupling from being mistakenly screwed by users to lead loosening or the male coupling from moving along with a spanner in assembly and disassembly to cause the loosening, thereby resolving the problem of preparation leakage.
Description
Technical field
The utility model belongs to field of air conditioning, relates in particular to a kind of rapid pipe joint linkage structure of field of air conditioning.
Background technique
The existing connecting head major part that is used for the connection between the pipeline all is to connect through the mode that is threaded, this structure that connects through the spiral shell mosquito separately, and misoperation is easy to occur seal for pipe joints property problem, brings a lot of inconvenience to the user.According to selling to external rapid pipe joint air conditioner user feedback over nearly 3 years; Installing an air-conditioner device or when moving dress and with spanner negative joint being connected or separating with male connector during air conditioner; Be installed on the air-conditioning stop valve male connector also can along with spanner in the process of turning and loosening phenomenon occurs, cause freezing medium leakage.And the air conditioner major part all is to adopt R22 as refrigeration agent at present, and the R22 refrigeration agent can damage ozonosphere, and price is relatively costly.If leak in the middle of the environment, not only destroyed environment, and the waste resource.In order to overcome this problem points; It is quite necessary that the linkage structure of male connector and air-conditioning stop valve is carried out design improvement; Improved rapid pipe joint guarantees that male connector and air-conditioning stop valve can only be screwed into to a direction rotation; The latch bar contacts with the draw-in groove of male connector when twisting in the other direction, latch sheet and male connector interlock under the effect of spring force and stuck.Therefore can solve the problem that causes freezing medium leakage because of misoperation well.
The model utility content
The main purpose of the utility model is to provide a kind of rapid pipe joint linkage structure, gets loose or when installing with dismounting, follows spanner in succession moving and the phenomenon that occurs getting loose causes the preparation leakage problem in order to prevent that positive rapid pipe joint from being twisted causing by user mistake.
To achieve these goals; The utility model provides a kind of rapid pipe joint linkage structure, comprises rapid pipe joint, connecting tube assembly, outdoor unit valve body, and the negative joint of said rapid pipe joint is connected with the connecting tube assembly; The male connector of said rapid pipe joint is threaded with the outdoor unit valve body; It is characterized in that: on the outdoor unit valve body, be provided with the valve body threaded joints, below said valve body threaded joints, be provided with the locking latch, on the end face of male connector, be provided with and lock the suitable draw-in groove of latch.
Above-mentioned rapid pipe joint linkage structure, said locking latch comprises latch bar and elastomer, elastomer is located at the below of latch bar.
Above-mentioned rapid pipe joint linkage structure, said elastomer is a metal spring.
Above-mentioned rapid pipe joint linkage structure, the bottom surface of said metal spring is fixed on the outdoor unit valve body.
Above-mentioned rapid pipe joint linkage structure, the latch bar is welded on the end face of metal spring.
The invention has the beneficial effects as follows: the utility model is provided with the valve body threaded joints on the outdoor unit valve body; Be provided with the latch bar below the valve body threaded joints, latch bar below is provided with spring, on the end face of male connector, is provided with and the suitable draw-in groove of latch bar; Thereby make valve body and male connector interlock; When rapid pipe joint during in installation or removal, male connector can not get loose from valve body, thereby avoids the phenomenon of freezing medium leakage.

Fig. 2 is the utility model male connector structural representation;
Fig. 3 is the structural representation of the outdoor valve body joint of the utility model;
Fig. 4 is the A portion enlarged view of Fig. 2;
Fig. 5 is the latch bar partial enlarged drawing on the utility model outdoor unit valve body.
Embodiment
A kind of rapid pipe joint linkage structure as shown in Figure 1; Comprise rapid pipe joint, connecting tube assembly 1, outdoor unit valve body 4; The negative joint 2 of rapid pipe joint is connected with connecting tube assembly 1, and the male connector 3 of rapid pipe joint is threaded with outdoor unit valve body 4, on outdoor unit valve body 4, is provided with valve body threaded joints 41; Below valve body threaded joints 41, be provided with the locking latch, on the end face of male connector 3, be provided with and lock the suitable draw-in groove of latch 31.The Placement of rapid pipe joint and air conditioner is such: an end of rapid pipe joint connecting tube assembly 1 and the inflow and outflow pipe 11 of indoor machine of air-conditioner are welded to connect; The other end is connected with negative joint 2; Negative joint 2 and male connector 3 socket connections, male connector 3 carries out screw thread with the outdoor unit valve body 4 of air conditioner and is connected.
To shown in Figure 5,4 are provided with valve body threaded joints 41 on the outdoor unit valve body in conjunction with Fig. 2, are provided with latch bar 42 below the valve body threaded joints 41, and latch bar 42 belows are provided with spring 43, on the end face of male connector 3, are provided with the draw-in groove 31 suitable with latch bar 42.During being connected of outdoor unit valve body 4 and male connector 3, when the bottom of male connector 3 contact latch bar 42, the latch on the latch bar 42 inserts with the downward propelling of male connector 3 in the draw-in groove 31 of male connector 3 and forms interlocks.When needs dismounting male connector 3, as long as press latch bar 42 downwards, oppositely twist male connector 3 again and get final product, operation is very easy.
When reverse misoperation; Because of latch bar 42 and male connector 3 interlocks; On the end face 421 that opposite force acts on latch bar 42 and 311 two contacted end faces of end face of draw-in groove 31,, can not produce component obliquely because end face is almost vertical (like Fig. 4, shown in Figure 5); Thereby latch bar and draw-in groove are broken away from, make male connector and valve body keep closely being connected.
