Description
Technical Field
The utility model relates to a draw the round pin, especially relate to a draw round pin with locking function.
Background
At present, the traditional pull pin does not have a locking and positioning structure design, and the pull pin is always kept in a state of being clamped in a pin hole due to the action of a spring when the traditional pull pin is used, so that the traditional pull pin cannot be fixed in a locked or unlocked state. When more than two pull pins need to be pulled open simultaneously, the pull pins cannot be fixed in an unlocking state one by one in sequence, and the operation by one person is very inconvenient; meanwhile, the existing pull pin cannot fix the pull pin in a locked state, and the condition of accidental slipping often occurs in the use process, so that an accidental condition is generated. Therefore, it is an urgent problem for those skilled in the art to develop a pull pin with a locking function.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned not enough, provide a draw round pin with locking function.
The above object of the present invention is achieved by the following technical solutions: a pull pin with a locking function comprises an outer sleeve, an inner rod, a spring and a knob, wherein a spring limiting necking part is arranged at the upper end of the outer sleeve, a spring clamping part is arranged on the inner rod, the spring is sleeved on the inner rod and is inserted into the outer sleeve together with the inner rod, one end of the spring is abutted against the spring limiting necking part, and the other end of the spring is abutted against the spring clamping part; the outer side end of the inner rod is connected with the knob, and the inner side end of the inner rod is provided with a clamping head.
Furthermore, the spring limiting necking part is a threaded hole, and the inner rod is provided with an external thread fixed on the spring limiting necking part at the inner side end, so that the clamping head of the inner rod cannot be easily separated from the spring limiting necking part due to external force.
Furthermore, the middle part of the inner rod is provided with a middle thread, and the spring limiting necking part is provided with a necking part internal thread matched with the middle part thread of the inner rod, so that the spring limiting necking part can be fixed in a shrinking state when the pull pin is pulled out.
Furthermore, the outer part of the outer sleeve is provided with a sleeve external thread which is matched and connected with the internal thread cylinder.
The utility model discloses an operation assembly and dismantlement process: under the locking state, under the action of the spring, the inner rod clamping head is clamped into the spring limiting necking part, and the knob is rotated to enable the external thread on the inner side of the inner rod to be locked into the spring limiting necking part, so that the pull pin can be fixed in the locking state. And under the unlocking state, the knob is rotated, the inner rod locked in the limiting necking part of the spring is loosened, the inner rod is pulled out, the clamping head is withdrawn, the middle thread is locked on the internal thread of the necking part, and the pull pin can be fixed in the unlocking state.
Compared with the prior art, the utility model the advantage be: the utility model discloses a locking function that the split pin can realize the unblock state is convenient for open the zip operation more than two simultaneously, also can fix the split pin at the state of locking, effectively prevents unexpected slippage.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a pull pin with a locking function comprises an outer sleeve 1, an inner rod 2, a spring 3 and a knob 4, wherein a spring limiting necking part 5 is arranged at the upper end of the outer sleeve 1, a spring clamping part 6 is arranged on the inner rod 2, the spring 3 is sleeved on the inner rod 2 and is inserted into the outer sleeve 1 together with the inner rod 2, so that one end of the spring 3 abuts against the spring limiting necking part 5, and the other end abuts against the spring clamping part 6; the outer side end of the inner rod 2 is connected with a knob 4, and the inner side end of the inner rod 2 is provided with a clamping head 7.
Furthermore, the spring limiting necking part 5 is a threaded hole, and the inner end of the inner rod 2 is provided with an external thread 8 fixed on the spring limiting necking part 5, so that the clamping head 7 of the inner rod 2 cannot be easily separated from the spring limiting necking part 5 due to external force.
Further, the middle of the inner rod 2 is provided with a middle thread 9, the spring limiting necking part 5 is provided with a necking part internal thread 10 matched with the inner rod middle thread 9, and therefore when the pull pin 6 is pulled out, the spring limiting necking part can be fixed in a shrinking state.
Further, the outer part of the outer sleeve 1 is provided with a sleeve external thread 11 which is matched and connected with the internal thread cylinder 5.
The utility model discloses an operation assembly and dismantlement process: under the locking state, under the action of the spring 3, the inner rod clamping head 7 is clamped into the spring limiting necking part, and the knob 4 is rotated to enable the external thread 8 on the inner side of the inner rod 2 to be locked into the spring limiting necking part, so that the pull pin can be fixed in the locking state. In the unlocking state, the knob 4 is rotated, the inner rod 2 locked in the limiting necking part 5 of the spring is loosened, the inner rod 2 is pulled out, the clamping head 7 is withdrawn, the middle thread 9 is locked on the internal thread 10 in the necking part, and the pull pin can be fixed in the unlocking state.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
