The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The invention will be described in detail below with reference to the drawings and alternative embodiments.

As shown in fig. 1 to 8, a pull rod device is disclosed as an embodiment of the present invention. As shown in fig. 1 to 5, the drawbar device includes a drawbar assembly 100 and a locking assembly 200. The locking assembly 200 is connected to the handle assembly 100. The length of the pull rod assembly 100 can be adjusted in a telescopic manner, and the locking assembly 200 is used for locking the pull rod assembly 100. Through the locking of locking Assembly 200 subassembly to pull rod Assembly 100, accomodate the back, pull rod Assembly 100 is difficult to become flexible, accomodates effectually, easy operation.

Specifically, the locking assembly 200 includes a locking socket 210 and a locking socket 220, and the drawbar assembly 100 includes an outer cylinder 110 and a drawbar subassembly 120; the locking sleeve seat 210 is arranged at one end of the outer cylinder 110, the pull rod subassembly 120 is telescopically received in the outer cylinder 110, and the locking sleeve head 220 is arranged at one end of the pull rod subassembly 120; when the drawbar subassembly 120 is received in the outer cylinder 110, the locking socket 220 can be locked to the locking socket 210. After the pull rod subassembly 120 is received in the outer cylinder 110, the locking sleeve head 220 and the locking sleeve seat 210 are mutually matched and locked, so that the pull rod subassembly 120 is not easy to loosen after being received.

More specifically, as shown in fig. 6 and 7, a groove 230 is formed on an inner surface of the locking sleeve holder 210 near one end of the locking sleeve head 220; correspondingly, a protrusion 240 is disposed on an outer surface of one end of the locking sleeve head 220 close to the locking sleeve seat 210. The groove 230 is arc-shaped, and the surface of the protrusion 240 is arc-shaped. After the drawbar subassembly 120 is received in the outer barrel 110, the projection 240 is located in the groove 230. The locking collar 220 is locked to the locking collar 210 by rotating the lever subassembly 120 so that the protrusion 240 is misaligned with the recess 230, i.e., the protrusion 240 is clear of the recess 230 and pressed against the inner surface of the locking collar 210, thereby compressing between the locking collar 220 and the locking collar 210. At this moment, the pull rod subassembly 120 is locked inside the outer cylinder 110 due to the matching of the locking sleeve head 220 and the locking sleeve seat 210, so that the looseness is not easy to occur, the storage effect is good, and the operation is simple. When the pull rod subassembly 120 needs to be pulled, the locking sleeve 220 is rotated reversely, the protrusion 240 on the locking sleeve 220 returns to the groove 230, and the pull rod subassembly 120 is in an unlocked state and can be pulled out from the outer cylinder 110 for use.

The number of the grooves 230 may be two, and the two grooves 230 are symmetrically disposed on the inner surface of the locking sleeve holder 210 with the central point of the locking sleeve holder 210 as the symmetric center; correspondingly, the number of the protrusions 240 is two, and the two protrusions 240 are symmetrically arranged on the outer surface of the locking sleeve head 220 by taking the central point of the locking sleeve head 220 as a symmetric center. The two grooves 230 and the two protrusions 240 are symmetrically arranged, and when the locking is performed, the two centrosymmetric parts are extruded and locked at the same time, so that the locking effect is better.

The locking sleeve head 220 comprises a first sub-sleeve head 221 and at least one second sub-sleeve head 222; the tie rod subassembly 120 includes a number of tie rods 121; the first sub-sleeve head 221 and the second sub-sleeve head 222 are respectively arranged at one end of the pull rod 121; the second sub-sleeve head 222 is located between the first sub-sleeve head 221 and the locking sleeve seat 210; the pull rod 121 is sequentially sleeved and telescopically received in the outer cylinder 110. One, two or more second sub-sleeve heads 222 can be arranged as required, so that the overall extensible length of the pull rod 121 device is increased.

Specifically, a protrusion 240 is arranged on the outer surface of one end of the first sub-sleeve head 221 close to the second sub-sleeve head 222; correspondingly, a groove 230 is formed on the inner surface of one end of the second sub-sleeve head 222 close to the first sub-sleeve head 221; the second sub-sleeve head 222 is provided with a protrusion 240 on the outer surface of one end close to the locking sleeve seat 210. The user can stretch the corresponding pull rod 121 by the corresponding first sub-sleeve head 221 or the second sub-sleeve head 222 according to the requirement. For example, if a user only wants to stretch the pull rod 121 corresponding to the second sub-sleeve head 222, the second sub-sleeve head 222 is rotated to be in the unlocked state, and at this time, the pull rod 121 connected to the second sub-sleeve head 222 can be pulled out, and at this time, the pull rod 121 connected to the first sub-sleeve head 221 is still in the contracted state; the same thing is true if the user only wants to stretch the pull rod 121 of the corresponding portion of the first sub-sleeve 221. Of course, the pull rod 121 of the corresponding portions of the first sub-sleeve head 221 and the second sub-sleeve head 222 can be pulled out at the same time, so as to achieve the maximum pulling elongation of the pull rod assembly 100. When the telescopic handle is contracted, the pull rod assembly 100 is directly pushed to contract, and the first sub-sleeve head 221 and the second sub-sleeve head 222 are rotated after the telescopic handle is contracted, so that the telescopic handle can be locked, the whole telescopic process is simple and convenient, and a user can selectively stretch the corresponding first sub-sleeve head 221 or second sub-sleeve head 222 according to the length requirement of the user.

Specifically, the number of the second sub-sleeve heads 222 is two; at least one pull rod 121 is arranged between the locking sleeve seat 210 and a second sub-sleeve head 222 close to the locking sleeve seat 210; at least one pull rod 121 is arranged between the two second sub-sleeve heads 222; at least one pull rod 121 is arranged between the first sub-sleeve head 221 and the second sub-sleeve head 222 close to the first sub-sleeve head 221.

The side of the first sub-sleeve head 221 away from the second sub-sleeve head 222 is provided with a connector 300 for connection. The connector 300 is used for connecting a clamping component for clamping electronic equipment such as a mobile phone. The end of the outer cylinder 110 away from the locking sleeve holder 210 is provided with a tail cap 400. The tail cap 400 is used to seal the outer cylinder 110.

As another embodiment of the present invention, a locking device is disclosed, comprising the locking assembly 200 as described above; or include a locking sleeve mount 210 as described above; or include the locking cuff 220 described above.

The foregoing is a more detailed description of the present invention, taken in conjunction with specific alternative embodiments, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
