Detailed description of the invention
Understandable for enabling the above-mentioned purpose of invention, feature and advantage to become apparent from, below the specific embodiment of the present invention is described in detail.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention can also adopt other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization when without prejudice to intension of the present invention, and therefore the present invention is not by the restriction of following public specific embodiment.
As shown in Figures 2 to 4, joint 1 provided by the invention includes joint body 11 and neck bush 12, described joint body 11 is connected with the first connector, and the endoporus 121 of described neck bush 12 matches with the second connector, and neck bush 12 can be connected by fit systems such as interference fit with the second connector；Described joint body 11 is provided with the pilot hole 111 suitable with the outer surface of described neck bush 12；Two ends on the axial direction of described neck bush 12 are provided with the first limiting section and the second limiting section, the first limiting section and the second limiting section and match with joint body 11, to limit described neck bush 12 play in described pilot hole 111.
During assembling, joint body 11 and the first connector can be linked together by mode well known in the art, such as welding or injection moulding integrated molding etc., neck bush 12 is spacing in the pilot hole 111 of joint body 11 by the first limiting section and the second limiting section, again the second connector is inserted in the endoporus 121 of neck bush 12, namely the purpose that the first connector and the second connector are connected has been reached by joint 1, to those skilled in the art, joint disclosed by the invention can be applied in any two parts according to demand needs in the structure connected.
First limiting section disclosed in this invention can be flange or the various structures such as buckle or boss, preparation for the ease of neck bush 12, described first limiting section includes the flange 122 being positioned at one end of described neck bush 12, described flange 122 matches with the edge of described pilot hole 111, and the concrete size of flange 122 is arranged according to the actual requirements.
In a preferred embodiment of the invention, described second limiting section includes at least two claw 123, and in Fig. 2 the disclosed embodiments, the second limiting section includes six claws 123, and six claws 123 are symmetrical arranged；One end of described claw 123 is fixing with described neck bush 12 to be connected, the other end of described claw 123 is provided with restriction protrusion 1232 and auxiliary section, described restriction protrusion 1232 matches with described pilot hole 111 to limit described neck bush 12 play in described pilot hole 111, described auxiliary section matches with the second connector to limit described second connector play in the endoporus 121 of described neck bush 12, so by restriction protrusion 1232 and auxiliary section by spacing for the position of neck bush 12 and the second connector, it is to avoid the second connector and other parts collisions and produce abnormal sound.
In another preferred embodiment of the invention, it is provided with gap 1231 between two adjacent described claws 123, described neck bush 12 is provided with gap 124, described gap 124 is connected with described gap 1231, so when neck bush 12 plugging in fitting hole 111, claw 123 has bigger deformation space, so that neck bush 12 is assembled together with the pilot hole 111 of joint body 11 more easily.It is highly preferred that in order to make, claw 123 is deformable has bigger intensity simultaneously, extends the service life of claw 123, and described gap 124 and described gap 1231 height along described neck bush 12 axial direction is equal.Additionally, for the limit effect ensureing restriction protrusion 1232, the outer wall of described restriction protrusion 1232 and described neck bush 12 forms the angle of 130 degree to 140 degree, namely in Fig. 4 α angle range for 130 degree to 140 degree.
In the another preferred embodiment of the present invention, described auxiliary section includes fitting projection 1233, described fitting projection 1233 matches with the draw-in groove on the second connector to limit the second connector play in the endoporus 121 of described neck bush 12, in addition, fitting projection 1233 also can with the second connector interference fit, effectively to limit the opposite direction play that the second connector inserts along the second connector through described pilot hole 111.
For the limit effect improving between neck bush 12 and pilot hole 111 and between fitting projection 1233 and the second connector, the outer wall of described restriction protrusion 1232 and described neck bush 12 forms the angle of 130 degree to 140 degree, the inwall of described fitting projection 1233 and described neck bush 12 forms the angle of 130 degree to 140 degree, and the face that described restriction protrusion 1232 and the outer wall of described neck bush 12 form the face of angle and the inwall formation angle of described fitting projection 1233 and described neck bush 12 is perpendicular.For Fig. 4, the angle that the outer wall of restriction protrusion 1232 and neck bush 12 is formed is α, the angle that the inwall of fitting projection 1233 and neck bush 12 is formed is β, the angle that the face of the face of the outer wall formation angle of restriction protrusion 1232 and neck bush 12 and the inwall formation angle of fitting projection 1233 and neck bush 12 constructs is γ, γ angle is the angle that the face on same claw 123 is formed, above-mentioned α angle and β angle range for 130 degree to 140 degree, γ angle is 90 degree, the power formed when the edge of restriction protrusion 1232 with pilot hole 111 can be coordinated by the claw 123 of this structure is effectively transferred to fitting projection 1233, so that neck bush 12 is tightr with coordinating of the second connector, thus more efficiently preventing from abnormal sound.
Present invention also offers a kind of pulling cable connecting mechanism, including shifting rocking arm 2, dragline pin 3, drag-line bar 4 and joint 1 disclosed above, those skilled in the art can be readily apparent that, joint 1 is not limited only in pulling cable connecting mechanism to use, it is possible to being applied to two parts needs in other structure connected.Described dragline pin 3 and the fixing connection of described shifting rocking arm 2, described joint body 11 is fixing with described drag-line bar 4 to be connected, and described dragline pin 3 matches with the endoporus 121 of described neck bush 12.In the present invention, dragline pin 3 and shifting rocking arm 2, joint body 11 and drag-line bar 4 all pass through the fixing connection of mode of quadric injection mould.
The material of neck bush 12 can be metal or plastics etc., it is preferable that described neck bush 12 can be made up of thermoplastic elastomer (TPE), to play damping noise reduction, decay is delivered to the effect of the vibratory output of shifting rocking arm 2 from drag-line bar 4, it is more preferred to, can be selected for TPEE or TEEE or TPVC.
Embodiment in Fig. 5 and Fig. 6, first drag-line bar 4 and joint body 11, shifting rocking arm 2 and zip pin 3 quadric injection mould are fixed, neck bush 12 inserts in the pilot hole 111 of joint body 11 along the one end with the second limiting section, restriction protrusion 1232 on the claw 123 of neck bush 12 limits the direction play that neck bush 12 inserts along neck bush, and flange 122 limits the opposite direction play that neck bush 12 inserts along neck bush；Inserting in neck bush 12 by zip pin 3 again, the fitting projection 1233 on the claw 123 of neck bush 12 coordinates, with the draw-in groove 31 on zip pin 3, the play limiting zip pin 3 in endoporus 121.This pulling cable connecting mechanism is not only easy for installation, and connection reliability is high, relative to the noise that original mode fixing by lock pin reduces, it is to avoid abnormal sound, and comfort is high.
Although the present invention is described in conjunction with above example, but the present invention is not limited to above-described embodiment, and it being only limited by the restriction of claims, it easily can be modified and change by those of ordinary skill in the art, but and without departing from the essential idea of the present invention and scope.
