The housing 10 further has a sliding groove 14, the sliding groove 14 being located between the first and second ends 12, 13 and being in communication with the first and second longitudinal notches 121, 131, the sliding groove 14 having an opening 141.
As shown in fig. 2 and 3, the housing 10 further has a cover 15, two opposite ends of the cover 15 have a pulling piece 16, and the cover 15 further has a plug portion 17 between the pulling pieces 16, and the plug portion 17 is sleeved with a sealing ring 18. In actual assembly, the cover 15 is inserted into the first and second longitudinal notches 121 and 131 of the base 11 by the respective lugs 16, and the opening 141 of the sliding groove 14 is closed by the plug 17 of the cover 15, so that the cover 15 is fixed to the base 11 and provides a better sealing effect by the seal ring 18 (as shown in fig. 4).
As shown in fig. 4, one end of the first sleeve T1 is inserted into a first circular hole 122 fixed to the first end portion 12 of the base 11, and one end of the second sleeve T2 is inserted into a second circular hole 132 fixed to the second end portion 13 of the base 11.
As shown in fig. 2 to 4, the first wire connecting member 20 has a fixing base 20A, the fixing base 20A is slidably received in the sliding groove 14 of the base 11, the fixing base 20A has a fixing portion 21, a bearing recess 25, and a receiving groove 26 between the fixing portion 21 and the bearing recess 25, and the fixing portion 21 has an axial through hole 22 and a radial screw hole 23 (as shown in fig. 4) communicating with the axial through hole 22. The first wire connecting piece 20 further has a tightening screw 24, as shown in fig. 4, where the tightening screw 24 is locked in the radial screw hole 23.
As shown in fig. 2 to 4, the second wire connecting member 30 has a diagonal groove 31 inclined from the upper left to the lower right on opposite sides thereof, and the second wire connecting member 30 also has a screw hole 32 (shown in fig. 4) penetrating in the axial direction, and a seating groove 33 communicating with the screw hole 32. The second wire connector 30 is slidably received in the sliding groove 14 of the base 11.
As shown in fig. 2 to 4, the return spring 40 is a coil spring in this embodiment, one end of the return spring 40 is accommodated in the accommodating groove 33 of the second wire connecting member 30 and abuts against the second wire connecting member 30, and the other end of the return spring 40 abuts against the second end 13 of the base 11, so that the return spring 40 provides an elastic restoring force acting on the second wire connecting member 30.
As shown in fig. 2 to 4, the spacing adjusting member 50 has a head portion 51 and a screw 54 connected to the head portion 51, and the outer peripheral surface of the head portion 51 has a plurality of operation grooves 52 arranged at intervals. The spacing adjustment member 50 is rotatably accommodated in the accommodating groove 26 of the first wire connecting member 20 by the head 51 on one hand, and the spacing adjustment member 50 is supported by the supporting recess 25 of the fixing base 20A of the first wire connecting member 20 by the screw 54 and is locked in the screw hole 32 of the second wire connecting member 30 on the other hand, so that the spacing adjustment member 50 is connected between the first and second wire connecting members 20, 30, and the first and second wire connecting members 20, 30 are spaced apart from each other.
The above is the structural feature of the cable connector 1 of the present utility model, and the following further describes the usage and the effects of the cable connector 1 of the present utility model.
As shown in fig. 5, one end of a first cable 60 is inserted into the first sleeve T1, so that the first cable 60 is inserted into the axial through hole 22 of the fixing seat 20A of the first cable connector 20 from the first end 12 of the base 11, and the first cable 60 is fixedly connected to the first cable connector 20 by tightening the first cable 60 with the tightening screw 24, and the other end of the first cable 60 is connected to a telescopic seat tube (not shown). On the other hand, one end of a second cable 70 is threaded into the second sleeve T2, so that the second cable 70 enters the sliding groove 14 from the second end 13 of the base 11, and since the second cable 70 is a flexible wire, the user can thread the second cable 70 through the chute 31 on one side of the second cable connector 30, wind the second cable around the other side of the second cable connector 30 and thread the second cable into the other chute 31, and then tie a knot 72 to fix the second cable 70, so that the second cable 70 is fixedly connected to the second cable connector 30, and the other end of the second cable 70 is connected to a lever (not shown) of the bicycle handle. It should be noted that, when the first and second cables 60 and 70 are fastened to the first and second wire connectors 20 and 30, the first cable 60 and the second cable 70 are both in a tensioned state.
When the user wants to adjust the tension of the second cable 70, the user only needs to detach the cover 15 from the base 11 as shown in fig. 6, and insert one of the paddles 16 of the cover 15 into one of the operation grooves 52 of the spacing adjustment member 50 to rotate the head 51 of the spacing adjustment member 50, so that the head 51 rotates relative to the first wire connecting member 20, and the second wire connecting member 30 is far away from the first connecting member 20 (as shown in fig. 6) or the second wire connecting member 30 is close to the first connecting member 20 (as shown in fig. 7). That is, the purpose of adjusting the spacing adjustment member 50 is to ensure that the two ends of the second cable 70 are in a tensioned state again, so that the first cable 60 can be smoothly pulled to open the valve (not shown) of the telescopic seat tube when the second cable 70 pulls the second wire connector 30, the spacing adjustment member 50 and the first wire connector 20.
When the user wants to adjust the height of the telescopic seat tube, a force is applied to the shift lever to pull the second cable 70 by an external force to drive the second wire connector 30 to move from a first position P1 shown in fig. 8 to a second position P2 shown in fig. 9, and the second wire connector 30, the spacing adjusting member 50 and the first wire connector 20 slide together with respect to the base 11, so that the return spring 40 is compressed by the second wire connector 30 to accumulate elastic restoring force, and the first cable 60 is pulled to open the valve of the telescopic seat tube, thereby adjusting the height of the telescopic seat tube. Once the telescopic seat tube is adjusted to a proper height, the force applied to the shift lever can be released, and at this time, the elastic restoring force released by the restoring spring 40 acts on the second wire connecting piece 30, so that the second wire connecting piece 30 returns to the first position P1 shown in fig. 8 from the second position P2 shown in fig. 9, and the first wire connecting piece 20 returns to the original position, so that the first cable 60 does not pull the valve of the telescopic seat tube any more to close the valve, and thus, the height of the telescopic seat tube is not changed any more, and the height adjustment of the telescopic seat tube can be completed.
In summary, the cable connector 1 of the present utility model seals the opening 141 of the sliding groove 14 of the base 11 by the cover 15, so that the cable connector 1 of the present utility model has good sealing performance, and the sealed housing 10 can protect the first wire connector 20, the second wire connector 30 and the spacing adjustment member 50 contained in the sliding groove 14 from foreign matters (such as rainwater, dust or sand), thereby reducing damage to the internal components of the housing 10.
While the foregoing is directed to embodiments of the present utility model, other and further details of the utility model may be had by the present utility model, it should be understood that the foregoing description is merely illustrative of the present utility model and that no limitations are intended to the scope of the utility model, except insofar as modifications, equivalents, improvements or modifications are within the spirit and principles of the utility model.
