Description
Technical field
This utility model belongs to the technical field of fastening of refrigerating equipment heavy type cabinet door, concrete a kind of refrigeration plant heavy door locking device.
Background technology
In order to ensure to seal preferably cold storage effect, large-scale refrigeration, the cabinet door of refrigerating equipment or storehouse door are typically all heavy door. the feature of heavy door is that quality is big, it is necessary to bigger power is turned on and off, and especially heavy door is when locking, it is necessary to apply bigger external force, and locking is had strict requirement, therefore, the locking device of locking heavy door is had strict requirement. locking device is varied, more common has spring locking device, hydraulic locking apparatus, eccentric locking device, screw-threaded coupling device, spring locking device locking state of spring in the process used is unstable, long-time use rear spring fatiguability needs to change, increase use cost, and the structure of hydraulic lock device is loaded down with trivial details, with high costs, eccentric locking device needs to apply bigger external force, and lock instability, long-time use abrasion is bigger, the still screw thread locking mechanism employed up to, locking is stable, reliably, cost is low, but existing screw thread locking mechanism is when locking, locking nut directly contacts with cabinet door mostly, the resistance of friction is big, need to apply bigger external force, plus comparatively heavy heavy door, higher requirement is had for operator, therefore, urgently can be employed with the device of the heavy cabinet door of less external force quick locking refrigeration plant.
Utility model content
Technical problem to be solved in the utility model is for drawbacks described above, it is provided that a kind of refrigeration plant heavy door locking device, simple in construction, during locking, externally applied forces is greatly reduced, and reduces the requirement to user, improves the efficiency of locking.
The technical scheme that this utility model solves the employing of its technical problem is as follows:
A kind of refrigeration plant heavy door locking device, including check lock lever, lock sleeve, described check lock lever and lock sleeve threaded engagement, lock sleeve is provided with the pressure head of activity near the front end of check lock lever, coordinate with plane bearing between pressure head with lock sleeve, locking backing stop structure it is provided with between plane bearing and pressure head, turn lock sleeve, lock sleeve is to check lock lever one side shifting, by heavy type cabinet door locking, when lock sleeve rotates, the pressure head of its front end contacts with heavy cabinet door, lock sleeve keeps relative rotation with pressure head, lock sleeve does not contact with cabinet door and greatly reduces frictional force, the external force being applied on lock sleeve is made to reduce, reduce the requirement to operator, improve the efficiency of locking.
Further, lock sleeve is provided with force handle away from the rear end of check lock lever.
Preferably, described force handle is Y type handle, and symmetrical Y type handle is easy to operator's operation, and the arm of force is long, reduces externally applied forces further.
Further, check lock lever is provided with external screw thread near lock sleeve one end, lock sleeve front end is provided with the female thread coordinated with check lock lever external screw thread, the check lock lever other end is attachment structure, rotation lock set, and the rotation of circumference is converted into axial motion by threaded engagement, to reach the purpose of locking, Efficient Conversion, only needs the less external force that circumferentially rotates just to obtain axially bigger thrust, reliable lock.
Further, described attachment structure is adapter sleeve, and adapter sleeve is fixed on refrigerating equipment and cabinet door relative position.
Further, described plane bearing is fixing with lock sleeve front end to be connected, and locking backing stop structure is inclined-plane backing stop structure, and plane bearing outer peripheral face is the conical surface, the less one end of the conical surface is forward, corresponding pressure head and plane bearing mating surface are the conical surface, and plane bearing increases contact area, makes the connection between pressure head and lock sleeve more reliable, both keep relatively rotating preferably simultaneously, cone match, it is possible to prevent the pressure head when locking to be moved rearwards by, it is ensured that the pressure head pressure to cabinet door.
The beneficial effects of the utility model are: adopt such scheme, lock sleeve and check lock lever threaded engagement, circumferentially rotate the purpose changing into axially-movable to reach locking, pressure head is in lock sleeve front end, avoid and contact between lock sleeve with cabinet door, greatly reduce the resistance of friction, so that the external force being applied on lock sleeve is greatly reduced, Y type handle increase the arm of force, promote that further externally applied forces reduces, reduce the requirement to operator, only need less external force turning handle, just the pressure head pressure to cabinet door it is converted into, it is achieved compress reliably, improve efficiency.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, this utility model is aforesaid be will become clear from other purpose, feature and advantage.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram in I portion in Fig. 1.
Wherein: 1 is check lock lever, 2 is lock sleeve, and 3 is pressure head, and 4 is plane bearing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
A kind of refrigeration plant heavy door locking device, including check lock lever 1, lock sleeve 2, check lock lever 1 lock sleeve 2 threaded engagement, check lock lever 1 is provided with external screw thread near one end of lock sleeve 2, lock sleeve 2 is provided with the female thread coordinated with check lock lever 1 external screw thread near the front end of check lock lever 1, the other end of check lock lever 1 is adapter sleeve, adapter sleeve connects on refrigeration plant, adapter sleeve is easy to quick installation, to improve efficiency, lock sleeve 2 front end is provided with the pressure head 3 of activity, pressure head 3 coordinates with plane bearing 4 with lock sleeve 2 front end, coordinate with conical surface thrust structure between plane bearing 4 with pressure head 3, plane bearing 4 is fixing with the front end of lock sleeve 1 to be connected, the outer peripheral face of plane bearing 4 one end on rear side of check lock lever 2 is the conical surface, the less one end of the conical surface is forward, plane bearing 4 front end is consistent with the front end of lock sleeve 2, corresponding pressure head 3 and the mating surface of plane bearing 4 are the conical surface, the rear end of lock sleeve 2 is symmetrical Y type hands handle, turn Y type handle locking set 2 rotation, due to threaded engagement, circumferentially rotating of lock sleeve 2 is changed into the axial linear movement near check lock lever 1 by screw thread, pressure head 3 front end contacts with cabinet door, when lock sleeve 2 rotates under the effect of plane bearing 4, pressure head 3 only keeps moving axially to compress cabinet door, do not contact between lock sleeve 2 with cabinet door, resistance is greatly reduced, so that the power being applied on lock sleeve 2 is substantially reduced, only need to apply less external force and just can make the cabinet door locking of heavy type, the Y type handle arm of force is long, further reduce externally applied forces, reduce the requirement to operator, improve the efficiency of reduction, during locking, lock sleeve 2 promotes pressure head 3 to advance, conical surface thrust structure moves after being prevented from pressure head 3, to ensure that axial thrust is delivered to cabinet goalkeeper's cabinet door locking completely, ensure the effect of locking.
The above; it it is only preferred embodiment of the present utility model; not this utility model is done any pro forma restriction, every according to any simple modification in technical spirit of the present utility model, above example made, equivalent variations, each fall within protection domain of the present utility model.
