Description

One kind is sealed to roll button

Technical field

The utility model be related to it is sealed roll button technical field, more particularly, to can prevent switch error operate it is a kind of sealed Roll button.

Background technology

It is sealed to roll the open and close that button is generally used for pipeline in the clinical practice of medicine equipment.But, actually facing In bed application, the pipeline for only needing to close without unlatching can be sometimes run into.

The existing sealed button that rolls is easily caused the mistake of operating personnel due to possessing the bidirectional operation function of opening and closing Operation, i.e., pipeline need closing when, it is sealed roll button be opened and so that pipeline is unlocked.Therefore, in order to prevent operating personnel For the sealed faulty operation for rolling button, it is necessary to research and develop it is a kind of can only functionally close and can not open it is sealed roll button, and It is traditional it is sealed roll to be buckled in structure be unable to reach this purpose.

Utility model content

The technical problems to be solved in the utility model is：The problem of existing for prior art there is provided it is a kind of functionally What can only be closed and can not open a kind of sealed rolls button.

The technical problems to be solved in the utility model is realized using following technical scheme：One kind is sealed to roll button, including rolls Body is detained, the button body that rolls takes the shape of the letter U hatch frame, latch hook is fixedly connected with U-shaped opening end side, at U-shaped opening end The opposite side formation locked groove relative with latch hook, and after latch hook grafting enters locked groove, the latch hook forms back-off structure simultaneously with locked groove It is mutually locked.

Preferably, the T-shaped structure of the latch hook, its inserted terminal formation pyramidal structure, the T-shaped structure of described locked groove, and The head sizes of latch hook inserted terminal are less than locked groove inlet portion size, and the tail dimension of latch hook inserted terminal is more than locked groove export department chi It is very little.

Preferably, described roll opens up the first slug hole and/or the 3rd slug hole on button body.

Preferably, first slug hole and/or the 3rd slug hole rolled on button body is triangle through hole.

Preferably, described roll opens up the second slug hole on button body.

Preferably, the bottom for rolling button body opens up the 4th slug hole.

Preferably, described roll sets the first anti-skidding convex tendon and/or the second anti-skidding convex tendon on button body outer surface.

Preferably, the first described anti-skidding convex tendon and/or the second anti-skidding convex tendon and roll button body between be integral chemical conversion Type structure.

Preferably, described latch hook and roll button body between be integrated molding structure.

Compared with prior art, the beneficial effects of the utility model are：Take the shape of the letter U hatch frame, make due to rolling button body Button body must be rolled and possess certain elastic deformation ability, when making the latch hook grafting of U-shaped opening end side in the presence of external force After into the U-shaped opening end opposite side locked groove relative with latch hook, latch hook and locked groove formation back-off structure are simultaneously mutually locked, so that It is sealed roll to be buckled in functionally can only close and can not open, therefore, effectively prevent the faulty operation of operating personnel.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with the accompanying drawings and specifically The utility model is described in detail embodiment.It should be appreciated that specific embodiment described herein is only to explain this Utility model, is not used to limit the utility model.

As shown in Figure 1, Figure 2, Figure 3 shows sealed rolls button, including rolls button body 1, and the described button body 1 that rolls takes the shape of the letter U out Mouth structure, the latch hook 4 of T-shaped structure is fixedly connected with U-shaped opening end side；Preferably, the latch hook 4 is with rolling button body 1 Between be integrated molding structure.Relative with latch hook 4 and T-shaped knot is formed in the U-shaped opening end opposite side for rolling button body 1 The locked groove 3 of structure, forms after the tail end of latch hook 4 is snapped fit onto in locked groove 3 under external force, between the latch hook 4 and locked groove 3 Buckle structure is simultaneously mutually locked, so as to so that it is sealed roll to be buckled in can only functionally close and can not open, effectively prevent behaviour Make the faulty operation of personnel.

Further, as shown in Fig. 2 the described T-shaped structure of latch hook 4, its inserted terminal formation pyramidal structure, described lock The T-shaped structure of groove 3, the head sizes L2 of the inserted terminal of latch hook 4 is less than the inlet portion size L3 of locked groove 3, the tail of the inserted terminal of latch hook 4 Portion size L1 is more than the export department size L4 of locked groove 3.Using such structure design, the inserted terminal of latch hook 4 is not only set to be used in outer masterpiece Under more easily grafting enter in locked groove 3, and after latch hook 4 and the clamping in place of locked groove 3, institute between the latch hook 4 and locked groove 3 The back-off structure of formation is relatively reliable, and between the two it is mutual it is locked more stablize, it is reliable, it is ensured that sealed roll is buckled in work( It can only close and can not open on energy, so as to be more effectively prevented from the faulty operation of operating personnel.

As shown in Figure 1 and Figure 2, the He of the second slug hole 5 is opened up in the same side branch at U-shaped opening end for rolling button body 1 3rd slug hole 7, opens up relative with the 3rd slug hole 7 the in the other side branch at U-shaped opening end for rolling button body 1 One slug hole 2, meanwhile, open up the 4th slug hole 8 in the bottom for rolling button body 1.Preferably, the first described slug hole 2, Three slug holes 7 use triangle through hole.By setting the first slug hole 2, the second slug hole 5, the 3rd slug hole 7 and the 4th to escape material Hole 8, can make the sealed Thickness Distribution for rolling button more uniform, when the sealed injection molding for rolling button is produced, can also make injection When stream it is more uniform, be conducive to improving the sealed integral molded plastic Forming Quality and elasticity for rolling button.

As shown in Figure 1, Figure 2, Figure 3 shows, it can be set on the outer surface of the side branch at the U-shaped opening end for rolling button body 1 The first anti-skidding convex tendon 6 is put, meanwhile, set second on the outer surface of the other side branch at the U-shaped opening end for rolling button body 1 Anti-skidding convex tendon 9；Described the first anti-skidding convex tendon 6, the second anti-skidding convex tendon 9 are with rolling between button body 1 preferably using integrated Molding structure, to reduce the sealed production cost for rolling button, and the connection of the first anti-skidding convex tendon 6 of guarantee, the second anti-skidding convex tendon 9 is reliable Property.Further, the first described anti-skidding convex tendon 6, the second anti-skidding convex tendon 9 can set some be parallel to each other respectively.It is logical The first anti-skidding convex tendon 6 of setting, the second anti-skidding convex tendon 9 are crossed, the sealed skin-friction force for rolling button body 1 can be increased, with convenient Operating personnel's firmly operates.

Preferred embodiment of the present utility model is the foregoing is only, not to limit the utility model, should be referred to Go out, all any modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc. all should be included Within protection domain of the present utility model.
