SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a rod locking and connecting mechanism, which aims to solve the technical problems that: the traditional rod connecting structure is complex in structure and inconvenient in modular assembly.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a pole locking coupling mechanism, includes female pole to and movable lock connects the son pole on female pole, be provided with on the female pole and supply the son pole to insert and lock the locking inner chamber of usefulness, one side that the son pole is close to female pole is equipped with the screw, and the spiro union has locking screw on the screw, has cup jointed the locking rubber ring between locking screw and the screw, thereby the locking rubber ring can hold tightly locking screw and realize the inflation with son pole locking in the locking inner chamber through locking screw's the tightening effect when the son pole inserts the locking inner chamber of female pole.
Furthermore, the outer diameter of the locking rubber ring is larger than the inner diameter of the locking inner cavity, and the outer diameter of the sub-rod is smaller than the inner diameter of the locking inner cavity.
Furthermore, a locking groove for the screw connection of the locking screw is further formed in the locking inner cavity, an inner ring of the locking groove is provided with an internal thread, and an outer ring of the nut of the locking screw is provided with an external thread.
Compared with the prior art, the utility model has the beneficial effects that:
(1) through setting up locking rubber ring and locking screw and locking inner chamber, just can lock the son pole in female pole through simple rotation, when needing the unblock, only need reverse twist out just can, it is very convenient.
(2) Through setting up the locking groove to set up internal thread and locking screw in the locking groove and set up the external screw thread, prevent sometimes that the locking rubber ring from holding tightly the locking screw and skidding and locking effect is not good.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
FIG. 2 is a second schematic view of the overall structure of the present invention.
FIG. 3 is a schematic view of the locking cavity and the locking groove of the female rod of the present invention.
In the figure: a female rod-1, a sub-rod-2, a locking cavity-3, a screw hole-4, a locking screw-5, a locking rubber ring-6 and a locking groove-7.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Referring to fig. 1 to 3, a rod locking and connecting mechanism comprises a female rod 1 and a male rod 2, wherein the male rod 2 is movably locked on the female rod 1, a locking cavity 3 for inserting and locking the male rod 2 is arranged on the female rod 1, the locking cavity 3 is a cylindrical cavity and extends from an upper opening of the female rod 1 to the inside of the female rod 1, the diameter of the locking cavity 3 is larger than that of the male rod 2, a screw hole 4 is arranged on one side of the male rod 2 close to the female rod 1, a locking screw 5 is screwed on the screw hole 4, a locking rubber ring 6 is sleeved between the locking screw 5 and the screw hole 4, specifically, the locking screw 5 is only partially screwed into the screw hole 4, an annular groove is formed between the left part and the end of the male rod 2, the locking rubber ring 6 is sleeved on the annular groove, after the locking rubber ring 6 is sleeved on the annular groove, the locking rubber ring 6 just surrounds the locking screw 5, and the locking screw 5 is a nut, so can not lock rubber ring 6 and can not drop, just block between nut and sub-pole 2 tip, as one of them preferred embodiment, the outside diameter of locking rubber ring 6 is greater than the inside diameter of locking inner chamber 3, the outside diameter of sub-pole 2 is less than the inside diameter of locking inner chamber 3, so alright with better messenger locking rubber ring 6 along with sub-pole 2 get into locking inner chamber 3 better hold tightly locking screw 5, because there is the extrusion effect.
As the third embodiment of this patent, still be provided with the locking groove 7 that supplies 5 spiro unions of locking screw on the locking inner chamber 3, locking groove 7 inner circle sets up the internal thread, the nut outer lane of locking screw 5 sets up the external screw thread, this kind of embodiment can be when locking rubber ring is not successfully hugged tightly locking screw 5, insert the pole on the locking groove 7 of the bottom of locking inner chamber with the son, let the external screw thread of locking screw 5 and the internal thread of locking groove 7 just block, as other implementation schemes, set up the arch on the outer edge of locking screw 5 nut, set up in protruding complex shrinkage pool in locking groove 7 and also can realize the screens effect, set up locking groove 7 alright prevent sometimes that locking rubber ring 6 from hugging tightly locking screw 5 skids and the locking effect is not good.
The utility model has wide application range, can be used for ordinary hand beats and poles, can realize the modular assembly of the beats or the poles by using the structure, and has the effects of more convenience, rapidness and stability compared with the traditional pole connecting mechanism.
The working principle of the utility model is as follows:
firstly, the locking screw is only partially screwed on the screw hole of the sub-rod, the part which is not screwed in is left, the locking screw and the sub-rod just form an annular groove, the locking rubber ring can be just sleeved, after the locking rubber ring is sleeved on the locking screw, the outer diameter of the locking rubber ring is larger than the inner diameter of the locking inner cavity, and the diameter of the sub-rod is far smaller than the diameter of the locking inner cavity, so that after the sub-rod drives the locking rubber ring to enter the inner cavity, the locking rubber ring can clasp the locking screw due to the extrusion effect, when the bottom of the locking inner cavity is reached, the rotor rod is rotated clockwise or the female rod is rotated anticlockwise, the locking rubber ring drives the screw hole of the screw rod to be screwed, thereby reducing the screw pitch (namely, the screw can be screwed towards the sub-rod, so that the length of the annular groove is shorter and shorter), thereby compressing the locking rubber ring, expanding the locking rubber ring, finally clamping the sub-rod in the locking inner cavity, when the unlocking is needed, the secondary rod only needs to be rotated anticlockwise or the primary rod only needs to be rotated clockwise, the locking screw can be unscrewed at the moment, the expansion of the locking rubber ring is gradually reduced, and finally the secondary rod can be pulled out.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
