In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
See also Fig. 1 and Fig. 2, the modular cable gland of the present embodiment comprises pedestal 1, locknut 2, clamping ring 3, clamping element 4.Clamping ring 3 and clamping element 4 are fabricated structure, make cable fixing head become modular cable gland.
Clamping ring 3 is assembled in pedestal 1, and locknut 2 to be screwed on pedestal 1 and by spacing for clamping ring 3 in pedestal 1.Clamping ring 3 can axially extend locknut 2, such locknut 2 can pressure holding on clamping ring 3, make, by the spacing clamping ring 3 in pedestal 1 of locknut 2, be there is preferably stability.
Clamping element 4 comprises flexible cylindrical shell 41, is fixed on the ring flange 42 of cylindrical shell 41 one end.Cylindrical shell 41 other end is inserted in clamping ring 3 by elastic deformation, and the spacing cylindrical shell 41 that makes outside clamping ring 3 of ring flange 42 is fixed with detachable mode and clamping ring 3.The external diameter of cylindrical shell 41 can be more than or equal to the internal diameter of clamping ring 3, when cylindrical shell 41 is inserted in clamping ring 3, needs the elastic deformation that cylindrical shell 41 is suitable.Be inserted in the cylindrical shell 41 in clamping ring 3 by elastic deformation, itself and clamping ring 3 fixing more stable, be not easy to loosen.When clamping element 4 disassembles from clamping ring 3 by needs, only need to operate ring flange 42.
By increasing the clamping element 4 with flange arrangement, the span scope of cable significantly increases, and the flange arrangement (i.e. ring flange 42) had also is convenient to the dismounting of cylindrical shell 41, and structure is simple, easy to operate.In the operation site of reality, if the cable selected 61 is comparatively thin, clip retention gripping members 4 installation enforcement can be carried out, as shown in Figure 3; If the cable selected is comparatively thick, clamping element 4 can be removed, the installation of large span cable diameter can be realized.
Clamping element 4 can be silicone rubber member, and clamping element 4 also can be integrated formed structure.Do not affecting under the prerequisite that cable passes through, not only the shape of ring flange 42 can arbitrarily be arranged, and ring flange 42 also can be arranged to the mode that be connected coaxial with cylindrical shell 41.Ring flange 42 can axially extend outside locknut 2, facilitates the disassembling section of clamping element 4.
Embodiment 2
See also Fig. 4 and Fig. 5, the modular cable gland of the present embodiment comprises pedestal 1, locknut 2, clamping ring 3, at least two clamping elements being plugged in together successively in detachable mode.Clamping ring 3 and at least two clamping elements are fabricated structure, make cable fixing head become modular cable gland.
Clamping ring 3 is assembled in pedestal 1, and locknut 2 to be screwed on pedestal 1 and by spacing for clamping ring 3 in pedestal 1.Clamping ring 3 can axially extend locknut 2, such locknut 2 can pressure holding on clamping ring 3, make, by the spacing clamping ring 3 in pedestal 1 of locknut 2, be there is preferably stability.
Each clamping element comprises flexible cylindrical shell, is fixed on the ring flange of described cylindrical shell one end; The cylindrical shell other end being positioned at the clamping element of outermost is inserted in clamping ring 3 by elastic deformation, and respective flange dish is spacing outside clamping ring 3, make corresponding cylindrical shell fix with detachable mode and clamping ring 3.
In the present embodiment, the quantity of clamping element is illustrated for two, i.e. clamping element 4, clamping element 5.Clamping element 4 comprises flexible cylindrical shell 41, is fixed on the ring flange 42 of cylindrical shell 41 one end; Clamping element 5 comprises flexible cylindrical shell 51, is fixed on the ring flange 52 of cylindrical shell 51 one end.
The clamping element being positioned at outermost refers to clamping element 4 in the present embodiment, and cylindrical shell 41 other end is inserted in clamping ring 3 by elastic deformation, and the spacing cylindrical shell 41 that makes outside clamping ring 3 of ring flange 42 is fixed with detachable mode and clamping ring 3.The external diameter of cylindrical shell 41 can be more than or equal to the internal diameter of clamping ring 3, when cylindrical shell 41 is inserted in clamping ring 3, needs the elastic deformation that cylindrical shell 41 is suitable.Be inserted in the cylindrical shell 41 in clamping ring 3 by elastic deformation, itself and clamping ring 3 fixing more stable, be not easy to loosen.When clamping element 4 disassembles from clamping ring 3 by needs, only need to operate ring flange 42.
Between adjacent two clamping elements, in the present embodiment, show as between clamping element 4 and clamping element 5.Cylindrical shell 51 other end being positioned at the clamping element 5 enclosed is inserted in the cylindrical shell 41 being positioned at peripheral clamping element 4 by elastic deformation, and outside the spacing ring flange 42 being positioned at peripheral clamping element 4 of the ring flange 52 being positioned at the clamping element 5 enclosed, the cylindrical shell 51 being positioned at the clamping element 5 enclosed is fixed with detachable mode and the clamping element 4 being positioned at periphery.
Have the clamping element 4 of flange arrangement and the quantity of clamping element 5 by increasing, the span scope of cable significantly increases, and the flange arrangement (i.e. ring flange) had also is convenient to the dismounting of clamping element, and structure is simple, easy to operate.In the operation site of reality, if the cable selected 62 is comparatively thin, clip retention gripping members 4 and clamping element 5 installations enforcement can be carried out, as shown in Figure 6; If the cable selected 61 is comparatively thick, clamping element 5 can be removed, a clip retention gripping members 4 is carried out installation and is implemented, as shown in Figure 3; If the cable selected is thicker, clamping element 4 and clamping element 5 all can be removed, the installation of cable realizing more large scale diameter.When clamping element size Selection is suitable, the installation of large span cable diameter can be realized.
Each clamping element can be silicone rubber member, and each clamping element also can be integrated formed structure.Do not affecting under the prerequisite that cable passes through, not only the shape of ring flange can arbitrarily be arranged, and ring flange also can be arranged to the mode that be connected coaxial with cylindrical shell.The ring flange 42 being positioned at outermost can axially extend outside locknut 2, facilitate the disassembling section of clamping element 4, by that analogy, between adjacent two clamping elements, be positioned at the ring flange 52 enclosed axially to extend and be positioned at outside peripheral ring flange 42, facilitate the disassembling section of clamping element 5.
In the present embodiment; just be enumerated the embodiment with two clamping elements; but this modular cable gland; be not limited to the above-mentioned scheme provided; a variety of mutation can be had; every those skilled in the art, not paying the mutation scheme of gained on new performing creative labour basis, all belong to protection range of the present utility model.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
