Abstract
The utility model proposes the pig house door improving bolt mechanism, comprise Frame door, bolt mechanism, the structure of bolt mechanism is: the outside of Frame door is welded with fairlead, T-shaped latch is installed by fairlead, outside Frame door, be welded with fixed head, eccentric wheel type knocker is arranged on fixed head; The handle of T-shaped latch is welded with transverse bar, forms inserted pin special; Transverse bar snaps in eccentric wheel type knocker, realizes inserted pin special locking.The utility model, under the prerequisite not changing traditional pig house door thematic structure, increases eccentric wheel type knocker and transverse bar, realizes the positive lock of inserted pin special, and under ensureing pig house door closure state, pig cannot be plowed, and realizes the reliable closedown of pig house door; Only have artificial rotating eccentricity to take turns, just can untie the locking of inserted pin special; The utility model small investment, easy to operate, safe and reliable.
Description
Technical field
The utility model relates to pig house, especially improves the pig house door of bolt mechanism.
Background technology
Tradition pig house door adopts steel bar welding to be connected into Frame door more, Frame door is welded with fairlead, fairlead installs T-shaped latch additional, jack is arranged on cement door pillar, and T-shaped latch is inserted in jack, realize the closedown of pig house door, because door air space ratio is comparatively large, the mobility of pig, and snoot is tapering, often circle door bolt is plowed and run away, bring very big hidden danger to safety in production.
Summary of the invention
In order to pig under ensureing pig house door closure state cannot be plowed, realize the reliable closedown of pig house door, the utility model proposes the pig house door improving bolt mechanism, comprise Frame door, bolt mechanism, the structure of bolt mechanism is: the outside of Frame door is welded with fairlead, T-shaped latch is installed by fairlead, it is characterized in that being welded with fixed head outside Frame door, and eccentric wheel type knocker is arranged on fixed head; The handle of T-shaped latch is welded with transverse bar, forms inserted pin special; Transverse bar snaps in eccentric wheel type knocker, realizes inserted pin special locking.
Beneficial effect: the utility model, under the prerequisite not changing traditional pig house door thematic structure, increases eccentric wheel type knocker and transverse bar, realizes the positive lock of inserted pin special, and under ensureing pig house door closure state, pig cannot be plowed, and realizes the reliable closedown of pig house door; Only have artificial rotating eccentricity to take turns, just can untie the locking of inserted pin special; The utility model small investment, easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the front view of eccentric wheel type knocker.
Fig. 3 is the lateral view of eccentric wheel type knocker.
Fig. 4 is special latch structure figure in the utility model.
Detailed description of the invention
As Figure 1 and Figure 4, further describe the utility model as follows: the pig house door improving bolt mechanism, comprise Frame door 1, bolt mechanism, the structure of bolt mechanism is: the outside of Frame door is welded with fairlead 2, T-shaped latch 3 is installed by fairlead 2, outside Frame door, be welded with fixed head 4, eccentric wheel type knocker 5 (being welded and fixed) is arranged on fixed head 4; The handle of T-shaped latch 3 is welded with transverse bar 6, forms inserted pin special (T-shaped latch 3, transverse bar 6); Transverse bar snaps in eccentric wheel type knocker 5, realizes inserted pin special locking.
As shown in Figure 2 and Figure 3, be the structure of eccentric wheel type knocker 5, be specially: be provided with draw-in groove 505 at the center of knocker body 1, on the upside of knocker body 1, be provided with eccentric wheel installation cavity 504, eccentric wheel 502 is installed by steady pin 503, and knocker body 1 realizes installing by installed surface 506; When rotating counterclockwise eccentric wheel 502, eccentric wheel 502 shutoff at the opening of draw-in groove 505, by eccentric throw, Action of Gravity Field hold mode; Only rotate clockwise eccentric wheel 502, eccentric wheel 502 is away from draw-in groove 505, and draw-in groove 505 opens wide, and shown in composition graphs 1, transverse bar 6 could depart from draw-in groove 505, opens inserted pin special.
