Abstract
The utility model provides a safety quick adaptor, which is characterized in that a safety rope is connected on the safety quick adaptor; on another end of the safety rope, a hook is connected. The front-end side wall of the safety quick adaptor is provided with a fixing ring; the safety rope and the connection end of the safety quick adaptor are connected with a fixing rod, the length of which is bigger than the max. inner diameter of the fixing ring of the safety quick adaptor. When an operator is checking the leakage of any hi-pressure gas, the safety hook is hooked on a U elbow of a heat exchanger of an air conditioner or other part that can hang the safety hook, so that the operator can be guaranteed to be safe because the safety hook and safety rope can pull the quick adaptor in case the quick adaptor bursts out due to the hi-pressure gas.
Description
Technical field
The utility model belongs to the air-conditioning production technical field, and relate to a kind of heat exchanger of air condition and fill pressurized gas leak detection rapid pipe joint, be a kind of joint safely and fast specifically.
Background technique
Heat exchanger is the vitals in the air-conditioning, and the quality of heat exchanger is the key that guarantees the air conditioner proper functioning, if leaking appears in heat exchanger, can directly have influence on the air conditioner proper functioning, even can't use.Therefore, in course of working,, need increase to fill pressurized gas leak detection operation for guaranteeing that heat exchanger does not leak.When detecting, rapid pipe joint is stuck on the cylindrical of heat exchanger of air condition inlet tube, outer pipe, and the joint by the high pressure nitrogen charging equipment is connected with rapid pipe joint and charges into gas (generally filling 3.0MPa nitrogen) and hunt leak.Because gas pressure is very big, in case clamping is not tight, rapid pipe joint will occurs and collapse and the operator's that injures problem.Therefore, how to solve rapid pipe joint and collapse and the operator's that injures problem, this has become problem demanding prompt solution in the air-conditioning production.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art and a kind of joint safely and fast is provided, and solves the common rapid pipe joint meeting operator's problem of injuring.
The purpose of this utility model is achieved through the following technical solutions: a kind of joint safely and fast is characterized in that: connect a safety rope on the described joint safely and fast, connect a hook on the other end of safety rope.The operator is carrying out pressurized gas when operation leak detection, hook is hooked in heat exchanger of air condition U elbow or other can tangle the parts of safety hook.
On the described front end side wall of joint safely and fast a retaining ring is set, safety rope is connected a fixing rod with joint connecting end safely and fast, and fixing rod length is greater than the retaining ring maximum inner diameter of joint safely and fast.
Described safety rope is a ring-type with the hook connecting end, and the hook rear portion is circular, and the annulus of hook interlocks with the looped end of safety rope.
The utility model compared with prior art has many advantages and good effect:
The utility model increases safety rope and hook in rapid pipe joint.The operator is when carrying out pressurized gas leak detection operation, safety hook is hooked in heat exchanger of air condition U elbow or other can tangle on the parts of hook, the rapid pipe joint of making provision against emergencies collapses under the pressurized gas effect, can hold rapid pipe joint by hook and safety rope, guarantees operator's safety.It is simple in structure, and is easy to make, and hook and safety rope easy installation and removal can be transformed existing rapid pipe joint, help applying.
Description of drawings
Fig. 1 is the utility model rapid pipe joint user mode figure.
Embodiment
Referring to Fig. 1, the embodiment of a kind of joint safely and fast of the utility model: welding one retaining ring on joint 4 distolateral walls safely and fast, have to connect a fixing rod on safety rope 3 one ends, fixing rod length is greater than the maximum inner diameter of joint 4 retaining rings safely and fast.Safety rope 3 penetrates from the retaining ring of joint 4 safely and fast, and fixing rod plays safety rope 3 is connected to effect on the joint 4 safely and fast.The other end of safety rope 3 is a ring-type, and it is circular that the rear portion of a hook 2 is arranged, and the annulus of hook 2 interlocks with the looped end of safety rope 3 and is connected.
The operator is carrying out pressurized gas when operation leak detection, hook 2 is hooked in heat exchanger of air condition U elbow or other can tangle on the parts of safety hook.When joint 4 will collapse safely and fast under the pressurized gas effect, can hold rapid pipe joint 4 by hook 2 and safety rope 3, prevent that joint 4 collapses safely and fast, can guarantee operator's safety.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (3)
1, a kind of joint safely and fast is characterized in that: connect a safety rope on the described joint safely and fast, connect a hook on the other end of safety rope.
2, according to the described joint safely and fast of claim 1, it is characterized in that: on the described front end side wall of joint safely and fast a retaining ring is set, safety rope is connected a fixing rod with joint connecting end safely and fast, and fixing rod length is greater than the retaining ring maximum inner diameter of joint safely and fast.
3, according to claim 1 or 2 described joints safely and fast, it is characterized in that: described safety rope is a ring-type with the hook connecting end, and the hook rear portion is circular, and the annulus of hook interlocks with the looped end of safety rope.
