Abstract

The invention relates to the technical field of rotary arm locking and provides a rotary arm device with a locking function. A rotary arm (1) is hinged to a fixed arm (2). A sliding groove is formed in one side of the rotary arm (1). A row of locking holes are formed in the position, opposite to an opening of the sliding groove, of the interior of the sliding groove. A sliding block (4) is mounted in the sliding groove of the rotary arm (1) and can slide freely along the sliding groove. One end of a supporting rod (3) is hinged to the fixed arm (2). The other end of the supporting rod (3) is hinged to the sliding block (4). A horizontal through unthreaded hole is formed in the sliding block (4). The head of a locking pin (5) is sleeved with a spring (6), penetrates through the unthreaded hole of the sliding block (4) and is in pin connection with one locking hole of the sliding groove. According to the rotary arm device with the locking function, the rotary arm is locked and assembled in one simple device, so that cost is reduced, the reliability is high, and locking of the rotary arm is realized. The rotary arm device with the locking function is simple and firm in structure, high in reliability, convenient to use and free of external condition restraints.

Description

A kind of rotating beam apparatus with lock function

Technical field

The present invention relates to spiral arm lock-in techniques field, particularly relate to a kind of rotating beam apparatus with lock function.

Background technology

In spiral arm locking, there is much version both at home and abroad, be generally adopted and spiral arm fixed form is locked, so causing that spiral arm stress is bad, it is convenient not to operate, and service efficiency is low, cost is higher, less economical, and is easily subject to external condition restriction.

Summary of the invention

It is an object of the invention to:

The present invention provides a kind of rotating beam apparatus with lock function, provides a simple and practical device for spiral arm locking, is applicable to spiral arm locking.

The technical scheme is that

A kind of rotating beam apparatus with lock function, including turning arm [1], fixed arm [2], support bar [3], slide block [4], stop pin [5], spring [6];

Wherein, turning arm [1] and fixed arm [2] are hinged, chute is had inside turning arm [1] side, in chute, the position relative with opening is provided with row's lock hole, slide block [4] is arranged in the chute of turning arm [1], and slide block [4] can along chute slidably, and support bar [3] one end is hinged with fixed arm [2], support bar [3] other end is hinged with slide block [4], and slide block [4] is provided with the stepped hole that horizontal direction is through; Stop pin [5] head is through stepped hole socket spring [6] of slide block [4], and then pin joint is in certain lock hole of chute, and spring [6] one end is stuck on the step of stepped hole, and spring [6] other end nut is spacing; During use, stop pin [5] is extracted from lock hole, rotate turning arm [1] to specified angle, slide block [4] moves to certain position along chute, decontrol stop pin [5], stop pin [5] recoils in another lock hole by spring [6], and slide block [4] is fixed, and turning arm [2] is locked at specified angle.

The invention has the beneficial effects as follows:

Spiral arm locking is integrated in a simple device by the present invention, reduces cost, and reliability is high, it is achieved spiral arm locks. Mechanism is simple, and firmly, reliability is high, easy to use, is not limited by external condition.
