Abstract
The utility model discloses a kind of inner locking type buckle press joint assembly, it belongs to engineering machinery field.It mainly includes the joint core body and sleeve cooperated, and the joint core body is provided with joint core external tooth, and sleeve Inner Front End is provided with sleeve internal tooth, and joint core external tooth and sleeve internal tooth are staggered；The joint core external tooth and sleeve internal tooth are trapezium structure.The utility model is simple in construction, easy to make, effectively improves the pressure-resistant performance of hose assembly, can substantially reduce fault ratio of hydraulic pressure system, improves whole machine operating efficiency, reduces maintenance cost.The utility model is mainly used in excavator or loading machine.
Description
Technical field
The utility model belongs to engineering machinery field, specifically, more particularly to a kind of inner locking type buckle press joint assembly.
Background technology
With engineering machinery hydraulic technology continue to develop and Construction Machinery Market competition it is increasingly fierce.Client is to digging
Requirement more and more higher in terms of the operating efficiency of the engineering machinery such as pick machine, loading machine, job stability, security.To realize
Whole machine high intensity is continuously worked, as the hose assembly of connection, and performance that its is pressure-resistant, which is required, to be improved.Therefore, it is guarantee system
System smooth working, improves the pressure-resistant performance of hose assembly and is necessary.
Existing hose assembly uses common fastened structure, and steel wire floor, which is not withheld, strengthens, and pressure-resistant performance is no more than
40Mpa, pulse is less than 400,000 times, and the phenomenon of pull-off, oil leak occurs in use, easily in hose assembly, so as to cause flexible pipe
Assembly failure, causes fault ratio of hydraulic pressure system to rise, stability reduction, has a strong impact on the operating efficiency of engineering machinery, adds
Whole machine maintenance cost and whole machine downtime.Meanwhile, hose assembly is pressure-resistant, and performance is too low, limits carrying for hydraulic system pressure
It is high, it is impossible to meet the market demand.
The content of the invention
The purpose of this utility model is to overcome drawbacks described above there is provided a kind of inner locking type buckle press joint assembly, and its structure is simple
It is single, it is easy to make, the pressure-resistant performance of hose assembly is effectively improved, fault ratio of hydraulic pressure system can be substantially reduced, whole machine work is improved
Efficiency, reduces maintenance cost.
Described inner locking type buckle press joint assembly, includes the joint core body and sleeve of mutual cooperation, the joint core sheet
Body is provided with joint core external tooth, and sleeve Inner Front End is provided with sleeve internal tooth, and joint core external tooth and sleeve internal tooth are staggered.
Further, the joint core external tooth and sleeve internal tooth are trapezium structure.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is handed over by setting up sleeve internal tooth and joint core external tooth, and by joint core external tooth and sleeve internal tooth
Mistake is set, and strengthens and steel wire floor on hose assembly is withheld, it is to avoid pull-off that hose assembly occurs in use, oil leak
Phenomenon, substantially increases the stability of hose assembly；
2nd, this practicality newly effectively increases the pressure-resistant performance of hose assembly, can substantially reduce fault ratio of hydraulic pressure system, improves
Whole machine operating efficiency, reduces maintenance cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state of the present utility model with reference to figure.
In figure, 1, joint core body；2nd, sleeve；3rd, sleeve internal tooth；4th, joint core external tooth；5th, steel wire floor；6th, hose assembly.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, inner locking type buckle press joint assembly, includes the joint core body 1 and sleeve 2 of mutual cooperation, it is described to connect
Head core body 1 is provided with joint core external tooth 4, and the Inner Front End of sleeve 2 is provided with sleeve internal tooth 3, and joint core external tooth 4 and sleeve internal tooth 3 are handed over
Mistake is set；The joint core external tooth 4 and sleeve internal tooth 3 are trapezium structure.
As shown in Fig. 2 the utility model is when in use, hose assembly 6 is sleeved on joint core body 1, steel wire floor 5 will
Hose assembly 6 is fixed, and last sleeve 2 is connected with joint core body 1, and hose assembly 6 is withheld, and the flexible pipe under this structure is total
1,000,000 subpulses can be carried out under high pressure 55Mpa into 6 without exception, substantially increase the stress-bearing capability of hose assembly 6, Jin Erti
The high overall pressure-resistant performance of hose assembly 6.
