Abstract

The utility model belongs to the technical field of fixing structures of small and medium devices, particularly relates to a spring type locking device, and solves the problem that an existing locking device is complicated in structure, high in production cost and complicated to operate and needs to have the aid of other dismounting tools sometimes; or is narrow in application field and not high in generality. The spring type locking device comprises a threaded sleeve, external threads are arranged on the outer wall of the threaded sleeve, the threaded sleeve is connected with a locking plate through the external threads, an axial through hole is arranged on the threaded sleeve, a boss I is arranged on the upper portion of the through hole, a boss II is arranged on the lower portion of a locking shaft, the locking shaft is arranged in the axial through hole of the threaded sleeve in a penetrating mode, a compression spring is sleeved on the locking shaft, a through hole is further arranged at the position of a fixed base corresponding to the locking shaft, and a cylindrical pin vertically arranged corresponding to the locking shaft is arranged on the upper portion of the locking shaft in a penetrating mode. The spring type locking device has the advantages of reducing production cost, and being rapid and simple in operation, high in generality and wide in practical application field. The spring type locking device does not need to have the aid of other removing tools.

Description

The spring locking device

Technical field

The utility model belongs to the technical field of medium and small sized unit fixed structure, is specifically related to a kind of spring locking device.

Background technique

There is following problem in existing locking device: complex structure, cost of production height; Complex operation, sometimes need be by other extracting tools; Perhaps application is narrow, versatility is not high.

Summary of the invention

The goal of the invention of the utility model:

1, guaranteeing under the situation that locking requires, adopting easy manufacturing, component that interchangeability is strong, thereby simplified structure, reducing production costs.

2, fitting operation mechanism in locking device is used for lock operation.

3, the parts in the locking device can carry out size adjusting according to actual conditions, to adapt to the lock function of specific device under specific environment.

The utility model adopts following technological scheme to realize:

A kind of spring locking device is characterized in that comprising the fixed base that is arranged on the fixed block I, is arranged at the lockplate on the fixture II, locking nut, pressure spring, swivel nut and lock shaft; Described swivel nut outer wall is provided with outside thread, and swivel nut is connected with lockplate through outside thread, and is locked by locking nut; Have axial hole on the swivel nut, the top of through hole is provided with the boss I, and the bottom of lock shaft is provided with the boss II; Lock shaft is arranged in the axial hole of swivel nut; Be with pressure spring on the lock shaft, the upper end of pressure spring is connected on the boss I, and the lower end of pressure spring is connected on the boss II on the lock shaft; The position of the corresponding lock shaft of fixed base also has through hole, and lock shaft top is equipped with its vertically disposed straight pin relatively.

Another preferred version of the utility model: the top of swivel nut has the elongated slot of perforation, and the straight pin correspondence is installed within the elongated slot.

Another preferred version of the utility model: the lock shaft top is connected with draw ring.

The utlity model has following beneficial effect:

1, adopted easy manufacturing, component that interchangeability is strong, parts are brief, simple in structure, guaranteeing farthest to have reduced cost of production under the locking reliable conditions.

2, operating device has been installed, has been used for lock operation, swift to operate, simple, need be by other extracting tools.

3, only need simply adjust part component in the locking device, can adapt to the locking requirement under the multiple situation, highly versatile, practical application area are extensive.

Description of drawings

Fig. 1 is the structural representation of the utility model

Among the figure: 1-draw ring, 2-straight pin, 3-swivel nut, 4-pressure spring, 5-locking nut, 6-lockplate, 7-lock shaft, 8-fixed base.

Embodiment

The spring locking device comprises the fixed base 8 that is arranged on the fixed block I, is arranged at the lockplate 6 on the fixture II, locking nut 5, pressure spring 4, swivel nut 3 and lock shaft 7; Described swivel nut 3 outer walls are provided with outside thread, and swivel nut 3 is connected with lockplate 6 through outside thread, and by locking nut 5 lockings; Have axial hole on the swivel nut 3, the top of axial hole is provided with the boss I, and the bottom of lock shaft 7 is provided with the boss II; Lock shaft 7 is arranged in the axial hole of swivel nut 3; Be with pressure spring 4 on the lock shaft 7, the upper end of pressure spring 4 is connected on the boss I, and the lower end of pressure spring 4 is connected on the boss II on the lock shaft 7; The position of fixed base 8 corresponding lock shaft 7 also has through hole, and lock shaft 7 tops are equipped with its vertically disposed straight pin 2 relatively.The top of swivel nut 3 has the elongated slot of perforation, and straight pin 2 correspondences are installed within the elongated slot.Lock shaft 7 tops are connected with draw ring 1.

The working principle of the utility model is to utilize the impacting force of pressure spring to realize locking.Pressure spring 4 is put into the axial hole of swivel nut 3, insert lock shaft 7; Again swivel nut 4 is screwed in respectively in locking nut 5, the lockplate 6, and adjust to suitable position (lock shaft 7 need fall into fixed base 8 through holes), tighten locking nut 5 at last, insert straight pin 2.

Lock shaft 7 laterally penetrate draw ring 1, during lock operation, only need a pull-up draw ring 1 state that just can unlock.

Except must processing the internal thread that cooperates with swivel nut 3, its structure can design (need guarantee be locked device reliably be connected) according to actual conditions on the lockplate 6; Lock shaft 7 length also can be adjusted according to lockplate 6 mounting points and fixed base 8 forms; According to the weight that is locked device, the reliability of operating mode of living in (transportation, vibration etc.) adjustment pressure spring parameter to realize locking.
