Abstract
The utility model discloses an assembling tool for an O-shaped seal ring. The assembling tool for the O-shaped seal ring is characterized by comprising an integrally formed outer diameter expansion section, a connecting rod section, and a guide section, wherein the outer diameter expansion section is that the outer diameter is gradually increased and the end of the outer diameter expansion section is toward to the direction of the connecting rod section, and the outer diameter of the end of the outer diameter expansion section is smaller than the inner diameter of the O-shaped seal ring. The connecting rod section is arranged at the front end of the outer diameter expansion section, the outer diameter of the connecting rod section is greater than the inner diameter of the O-shaped seal ring and greater than or equal to the outer diameter of a joint to be mounted. The guide section is arranged at the front end of the connecting rod section and the outer diameter of the guide section is smaller than that of the connecting rod section, so that the guide section is inserted into the joint to be mounted. The end of the assembly tool with a small diameter is pushed into the sealing ring until a part of a big diameter so as to expand the O-shaped seal ring and be convenient to assemble on the joint to be mounted, so that labor intensity is reduced, and assembly efficiency is improved. The sealing ring is not easy to scratch, service life is prolonged, and a seal effect after assembly is ensured.
Description
Technical field
The utility model relates to a kind of assembly tool, especially a kind of fast assembly of tools of O RunddichtringO.
Background technology
In the engineering machinery of chemical industry, petrochemical industry, electromechanical engineering, oil circuit, hydraulic pressure etc., when relating in particular to some sealing devices, need in the seal channel of some circular part, embed the O RunddichtringO, guarantee the sealing property of pipeline.Such as leather pipe joint, one is outer silk, and one connects leather hose, tracheae, oil pipe etc.Excircle at leather pipe joint offers groove, the O RunddichtringO need to be fitted in the groove, in order to play the effect of sealed pipe fittings.
When assembling O RunddichtringO, the existing practice normally by manually with the hand sealing ring of taking, then sealing ring is aimed at leather pipe joint, pack into again in the groove of leather pipe joint after sealing ring is pulled open.But because the sealing ring shape is less, there is again oiling on the surface, so manual operations is relatively more difficult, and efficient is very low.And sealing ring is easy to affected inevitably the sealing effectiveness of sealing ring by the scuffings such as corner angle of leather pipe joint in installation process, has reduced the service life of sealing ring, has increased cost, and has caused the hidden danger of leaking.
The utility model content
Technical problem to be solved in the utility model provides that a kind of efficiency of assembling is high, the O RunddichtringO assembly tool of good seal performance after the assembling.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of O RunddichtringO assembly tool, it is characterized in that, comprise integrated external diameter expanding reach, connecting rod section and guide section, described external diameter expanding reach is increased towards described connecting rod section direction external diameter gradually by end, and the external diameter of described external diameter expanding reach end is less than the internal diameter of described O RunddichtringO; Described connecting rod section is positioned at the front end of described external diameter expanding reach, and the external diameter of described connecting rod section is greater than the internal diameter of described O RunddichtringO and more than or equal to the external diameter of joint to be installed; Described guide section is positioned at the front end of described connecting rod section and external diameter less than the external diameter of described connecting rod section, in order to be inserted in the described joint to be installed.
Preferably, the end of described external diameter expanding reach is pointed shape, the pushing of the sealing ring of being more convenient for.
Compared with prior art, the utility model has the advantage of: by pushing sealing ring from the little end of the external diameter of assembly tool until to the larger part of external diameter with the expansion sealing ring so that it is convenient to be assembled to joint to be installed, reduce labour intensity, improved efficiency of assembling; Sealing ring is not easy to be scratched, and long service life has been guaranteed the sealing effectiveness after the assembling.
Description of drawings
Fig. 1 is the structural representation of assembly tool of the present utility model and joint to be installed;
Fig. 2 is the cutaway view of assembly tool of the present utility model and joint to be installed.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of O RunddichtringO assembly tool, comprise integrated external diameter expanding reach 11, connecting rod section 12 and guide section 13, external diameter expanding reach 11 namely increases to connecting rod section 12 direction external diameters gradually by holding endwise, and its terminal external diameter is less than the internal diameter of O RunddichtringO 2, preferably, end is pointed shape.
Connecting rod section 12 is positioned at the front end of external diameter expanding reach 11, and its external diameter is greater than the internal diameter of O RunddichtringO 2, so that expansion O RunddichtringO 2.Guide section 13 is positioned at the front end of connecting rod section 12, and external diameter is less than the external diameter of connecting rod section 12, in order to cooperate with joint 3 to be installed.
Joint 3 to be installed has endoporus 31, and guide section 13 can be inserted in this endoporus 31, and the external diameter of joint 3 to be installed is less than or equal to the external diameter of connecting rod section 12, and its end is connected to the front end of connecting rod section 12.Offer the groove 32 of annular on the periphery wall of joint 3 to be installed, be used for assembling O RunddichtringO.
When assembling, the endoporus 31 that guide section 13 is inserted into joint 3 to be installed is interior until the front end butt of the end of joint 3 to be installed and connecting rod section 12; Then, O RunddichtringO 2 pushed away along the tip forward end of external diameter expanding reach 11 until shift onto on the connecting rod section 12, the internal diameter of O RunddichtringO 2 enlarges thus, can disposable a plurality of O RunddichtringOs 2 be shifted onto on the connecting rod section 12; Then, foremost O RunddichtringO 2 is continued to push away forward, because the external diameter of joint 3 to be installed is less than or equal to the external diameter of connecting rod section 12, O RunddichtringO 2 can promote forward comparatively easily, until snap onto in the groove 32, finishes thus assembling.
The above only is preferred embodiment of the present utility model; should be pointed out that for the ordinary skill in the art, do not breaking away under the principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
