Abstract

The utility model discloses a safety plug pin which comprises a pin base, wherein the pin base is correspondingly welded on the edge of a pin hole of a fixed device, a longitudinal groove is formed in the wall of the pin base, a horizontal clamping groove is formed in each of the two ends of the longitudinal groove, a pin is arranged in the pin base and is provided with a handle, and the handle is clamped into the upper horizontal clamping groove or into the lower horizontal clamping groove when in a working state or in a non-working state respectively. According to the safety plug pin, the structure of an original plugging device is not changed, plugging is reliable, the structure is novel, manufacturing is simple, the number of processes is small, replacement is easy to achieve, the using method is simple, accidents can not happen easily, and then production efficiency can be improved and economic effectiveness is improved.

Description

Safety pin

Technical field

The utility model belongs to mechanical equipment technical field, relates to a kind of safety pin.

Background technique

In metallurgical equipment, latch is a widget that frequency of utilization is very high, existing latch is all to weld chainlet on bearing pin, insert pin-and-hole during use, the used time does not extract and inserts on special-purpose key seat from pin-and-hole, or hangs on chainlet, when being used, this kind of latch waste time and energy, during manufacture, operation is many and take material, is difficult for replacing, affects the work of miscellaneous part in easily forgetting the insertion key seat in used time not in production and causes having an accident.

The model utility content

The purpose of this utility model is to provide a kind of safety pin, solved when safety pin of the prior art is used and wasted time and energy, during manufacture, operation is many and take material, is difficult for replacing, affects the work of miscellaneous part in easily forgetting the insertion key seat in used time not in production and causes having an accident.

The technological scheme that the utility model adopts is, a kind of safety pin, comprise key seat, and the key seat correspondence is welded on the pin-and-hole opening's edge of fixed equipment, on the wall of key seat, has cannelure, and the two ends of cannelure are respectively arranged with a horizontal draw-in groove; Be provided with pin in key seat, pin is equipped with handle.

Safety pin of the present utility model, its characteristics also are:

Handle by threading path to the upper end that is connected to pin.

The beneficial effects of the utility model are, do not change the structure of former docking device, peg graft reliable, and novel structure, manufacture succinctly, and operation is few, easily changes; Using method is simple, is difficult for having an accident, thereby can enhances productivity, and increases economic benefit.

In figure, 1. key seat, 2. handle, 3. pin, 4. fixed equipment, 5. vehicular equipment, 6. cannelure.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Figure 1, the structure of the utility model safety pin is, comprises key seat 1, and key seat 1 correspondence is welded on the pin-and-hole opening's edge of fixed equipment 4, has cannelure 6 on the wall of key seat 1, and the two ends of cannelure 6 are respectively arranged with a horizontal draw-in groove; Be provided with pin 3 in key seat 1, pin 3 is equipped with handle 2.Handle 2, according to working state or off working state, snaps in respectively in the horizontal draw-in groove of lower end or upper end.

In embodiment, handle 2 by threading path to the upper end that is connected to pin 3.

As shown in Figure 2 and Figure 3, when vehicular equipment 5 needs pin 3 and fixed equipment 4 positions fixedly, by the pin-and-hole centering on the jack on vehicular equipment 5 and fixed equipment 4, then in jack pin 3 inserted on vehicular equipment 5, handle 2 is inserted in the horizontal draw-in groove in lower end of key seat 1 simultaneously, realize the insurance location, now safety pin is in running order.

As shown in Figure 4, Figure 5, when vehicular equipment 5 does not need fixed position, handle 2 is shifted out from key seat 1 lower end draw-in groove, pin 3 is outwards screwed out, handle 2 is inserted in the horizontal draw-in groove in upper end of key seat 1, vehicular equipment 5 is in free movement state again, and safety pin is in the idle state.

Existing latch is provided with chainlet, is with special-purpose key seat, and chainlet generally carries out erection welding, operation more complicated; The safety latch can directly weld when making equipment, does not need the assembling weldering, and operation is simple.When existing latch inserts, waste time and energy, the safety latch assigns in equipment all the time, during insertion, saves time and strength.Existing latch is welded on key seat with chainlet all the time, and the pin of safety latch and key seat, for the not welding that is threaded, are changed more convenient; The safety latch not the used time do not need to insert specially key seat, can not affect the work of miscellaneous part, effectively reduced the generation of production accident, improved manufacturing efficiency.
