Fig. 2 shows the assembling condition schematic representation of the tamper discharge pipe connections of Fig. 1;
Fig. 3 shows the structural representation of operation unit of the tamper discharge pipe connections of Fig. 1; And
Fig. 4 shows the structural representation of connector portions of the tamper discharge pipe connections of Fig. 1.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
As depicted in figs. 1 and 2, the tamper discharge pipe connections of present embodiment comprises operation unit 10 and connector portions 20; Connector portions 20 has threaded ends; Wherein operation unit 10 is connected through safety pin 13 with connector portions 20.
When the tamper discharge pipe connections is installed and used, earlier operation unit 10 is applied moment of torsion, the union nut that makes operation unit 10 drive connector portions 20 rotations and air conditioner assembles; Connector portions 20 and union nut are closely cooperated, continue operation unit 10 is applied moment of torsion, cooperate the closelyst until connector portions 20 with union nut, coolant leakage can not take place; At last, operation unit 10 selectively disassembles; Wherein the intensity of safety pin 13 is set according to the concrete needs of assembling.The tamper discharge pipe connections of the utility model is simple in structure, easily assembling.
Like Fig. 3 and shown in Figure 4, the operation unit 10 of the tamper discharge pipe connections of present embodiment also comprises the stressed shell of column 17 and double-screw bolt section 15 that has stress surface; Double-screw bolt section 15 extends axially along stressed shell of column 17 from the end face of stressed shell of column 17, and double-screw bolt section 15 has outside thread, and the end face of the stressed dorsad shell of column 17 of double-screw bolt section 15 is provided with safety pin 13.Be provided with like this, operation unit 10 can be screwed onto on the union nut according to concrete needs, is easy for installation and removal.Preferably, also have on the end face of flange 25 along connector portions 20 axially extended abutment sleeves 27; Abutment sleeve 27 has the through hole of penetrator portion 20; The position of corresponding abutment sleeve 27 has endoporus 19 on the double-screw bolt section 15.Abutment sleeve 27 cooperates with endoporus 19; In assembly process, make operation unit 10 and connector portions 20 not produce the relative depature of position; Avoid safety pin 13 unbalance stress; Wherein the through hole of connector portions 20 and endoporus 19 are used for placing adapter, make two adapters dock or place an adapter through pipe joint.
