Abstract

The utility model discloses an interlocking mechanism for vertical antenna poles, and relates to a locking device between joint pipes of vertical antenna poles in the field of wireless communication, measuring and control equipments. The utility model consists of an upper hook, a middle hook and a lower hook, a pressure spring, a damping ring, a sliding block, an axis of rotation and a bracket and so on. The utility model adopts the relative movement between the upper hook, the middle hook and the lower hook to automatically lock or unlock the joint pipes of the vertical antenna poles and to interlock rising and falling of joint pipes of the vertical antenna poles. The utility model has the advantages of simple structure, being convenient to be processed and installed, stable and reliable locking, locking or unlocking according to rising and falling operation sequence, long performance life and esthetic appearance and so on. The utility model is an automatically locking fixing device particularly applicable for sleeves which move in a linear way.

Description

Vertical antenna bar interlock

Technical field

The utility model relates to the interlock between each pipe joint of vertical antenna bar in a kind of radio communication, the measuring and controlling equipment field, be specially adapted to various have between the mutual rectilinear motion sleeve pipe make the auto lock fixture.

Background technology

Chinese patent, the patent No. are the multi-functional geometrical clamp that discloses a kind of Pneumatic elevation mast in 92232518.9 the patent, its employing eccentric mechanism of this multi-functional geometrical clamp reaches locking and respectively saves the vertical antenna bar, though can lock reliable and stable, but the lifting locking of its each joint needs operation manually, use trouble inconvenient, complex structure is made difficulty, and cost is higher.

Summary of the invention

The purpose of this utility model is to avoid the weak point in the above-mentioned background technology and a kind of vertical antenna bar interlock that can lock automatically or open is provided, and the utlity model has simple in structure, reliable and stable, the characteristics such as the descending operation process is locked in order or opened, long service life, good looking appearance of locking.

The purpose of this utility model is achieved in that it is by rotating shaft 1, shelves ring 2, slide block 3, middle hook 4, rise to the bait 5, following hook 6, mounting 7, stage clip 8,9 constitute, its shaft 1 two ends are movably arranged on the mounting 7 both sides deckle boards, middle hook 4 upper end axis holes, rise to the bait 5 intermediate shaft hole movable sets on rotating shaft 1 axostylus axostyle, middle hook 4, rise to the bait and 5 be installed in mounting 7 frames, stage clip 8 one end hooks are lived in hook 5 upper ends, elasticity is fitted in the mounting 7, hook 4 upper ends during stage clip 9 one end hooks are lived, elasticity is fitted in the mounting 7, slide block 3 is slidingly mounted between middle hook 4 and mounting 7 inwalls, following hook 6 usefulness securing members are fixedly mounted on mounting 7 upper frame, shelves ring 2 usefulness securing members are fixed on the mast tube wall, and mounting 7 is screwed in each joint mast pipe upper end.

The utility model is compared background technology following advantage:

1 the utility model is provided with the mutual locking member of upper, middle and lower hooks, can realize the vertical antenna bar each the joint between auto lock or open, reach vertical antenna bar lifting purpose.

2 the utility model interlocking members are few, simple in structure, and process and assemble is convenient, lock reliable and stable, no wear-out part, long service life, good looking appearance.

3 the utility model can lock or open by the descending operation procedural order of mast, joint day spool on mast rises locking the most earlier, when descending, open the most following joint day spool earlier, can not axially move mutually after rising or decline put in place, suitable work has the auto lock fixture between the mutual rectilinear motion sleeve pipe.

Embodiment

With reference to Fig. 1, the utility model by rotating shaft 1, shelves ring 2, slide block 3, middle hook 4, rise to the bait 5, hook 6, mounting 7, stage clip 8,9 constitute down.Its shaft 1 two ends are movably arranged on the mounting 7 both sides deckle boards, hook 4 in the work, 5 the rotation axis of rising to the bait, and embodiment adopts steel pole materials processing to form.Mounting 7 is used for installing and fixing each interlocking member, and embodiment adopts steel plate materials to be processed into the rectangle box structure, is screwed in each joint mast pipe upper end.In hook 4 the upper end axis hole and rise to the bait 5 intermediate shaft hole movable set on rotating shaft 1 axostylus axostyle, be installed in mounting 7 frames, structure 4, the 5 usefulness steel plate materialses of rising to the bait are processed into sheet upper and lower side hook type structure among the embodiment, as the interlocking Lock Part.Elasticity is fitted in the mounting 7 after pressing bullet 8 one end hooks to live in hook 5 upper ends, elasticity was fitted in the mounting 7 after stage clip 9 one end hooks were lived middle hook 4 upper ends, make and rise to the bait 5, middle hook 4 can do to move clockwise or counterclockwise under the elastic acting force of stage clip 8,9, hook or open day spool and carry out interlocking.Embodiment stage clip 8,9 adopts the spring steel wire coiling to be processed into the stage clip structure.Between hook 4 and mounting 7 inwalls, slide block 3 is slided up and down under middle hook 4 active forces during the utility model slide block 3 is slidingly mounted on, simultaneously also as in hook 4 move left and right positioning actions, embodiment adopts steel plate materials to be processed into rectangle bulk structure.Following hook 6 usefulness securing members are fixed on mounting 7 upper frame, make mast interlocking Lock Part, and embodiment adopts steel plate materials to be processed into sheet hook type structure.Shelves rings 8 usefulness fasten on the mast tube wall, and embodiment processes with steel plate materials, as rise to the bait 5, the lock in place parts of middle hook 4.Embodiment installs an interlock at each pitch circle Guan Shangjun of vertical antenna bar, guarantees respectively to save the locking of day spool or open, and the utility model is also made interlock applicable to having between the mutual rectilinear motion sleeve pipe simultaneously.

The utility model course of work is as follows: when mast rises, shelves ring 8 is pushed down 5 the last end hook of rising to the bait, making rises to the bait 5 rotates around the axis, 5 rotations of rising to the bait make end hook disengagement on its following hook 6 that descends end hook and outer pipe, and pipe can rise, and following hook 6 descends relatively, 1 rotation around the shaft of middle hook 4, its following end hook clockwise rotate, when the internal layer pipe rose to desired location, middle hook 4 hooked shelves ring 8 lower ends under stage clip 9 effects, the internal layer pipe can not be descended be locked.When mast descends, following hook 6 upwards promotes slide block 3, hook 41 rotates around the shaft in making, end hook rotates counterclockwise under it, 4 times end hooks of hook are thrown off with shelves ring 2 in making, rising to the bait simultaneously 5 also rotates counterclockwise, and makes that end hook hooks engagement on rise to the bait 5 times end hooks 6 and the following hook, and inner layer pipe and outer tube no longer slide-and-lock are fixed.
