Description

A kind of novel swimming pool ladder

Technical field:

The utility model relates to the sports apparatus technical field, refers in particular to a kind of novel structure, prevents to get rusty, easy accessibility, safe and reliable novel swimming pool ladder.

Background technology:

Swimming is loved by the people as a kind of motion of CRUX, plays along with more and more people come swimming pool swimming, and the various swimming equipment in the swimming pool is also well-equipped thereupon.Wherein, the swimming pool ladder can help to like the people that the dive diving of ascending a height, and has made things convenient for people to play and has played.Traditional swimming pool ladder structure is by screw pedal to be fixed between two ladders, when disassembly and assembly, needs to use Phillips screwdriver with screw-driving or unclamp, and has expended staff's regular hour; And service time one is long, and the screw on the swimming pool ladder can produce corrosion, influence attractive in appearancely, even causes fixing the becoming flexible of pedal, brings certain potential safety hazard.

Summary of the invention:

The purpose of this utility model is exactly a kind of novel structure of providing at the deficiencies in the prior art part, prevent to get rusty, easy accessibility, safe and reliable novel swimming pool ladder.

For achieving the above object; the utility model includes: two tubular ladders and several pedals; several pedals are distributed between the two tubular ladders by the body that is located at the pedal two ends is sheathed; the external cylindrical surface of tubular ladder and be set in and be provided with convex screens and the spill draw-in groove that cooperatively interacts, plays fixation between the inwall of its upper sleeve body, and on the outer circumference surface of body, also be socketed with the protective sleeve that plays the role of fastening.

After adopting said structure, body and protective sleeve can adopt nonmetals to make, and will avoid producing corrosion phenomena like this; And need not special tool when its novel structure, handsome in appearance, dismounting, efficient and convenient; The fastening structure of protective sleeve has guaranteed the safe and reliable of this new structure; Its structure has overcome many weak points of traditional swimming pool ladder.

The specific embodiment:

Shown in accompanying drawing 1～12: the utility model includes: two tubular ladder 10 and several pedals 20; body 21 sheathed are distributed in two tubular ladders 10 between of several pedals 20 by being located at pedal 20 two ends; the external cylindrical surface of tubular ladder 10 and be set in and be provided with convex screens 30 and the spill draw-in groove 40 that cooperatively interacts, plays fixation between the inwall of its upper sleeve body 21, and on the outer circumference surface of body 21, also be socketed with the protective sleeve 50 that plays the role of fastening.Described protective sleeve 50 screws on the outer circumference surface that is socketed in body 21 by screw thread.The described protective sleeve 50 that is threaded on the body 21 part outer circumference surfaces is positioned at the same circumference sectional position with the convex screens 30 and the spill draw-in groove 40 that cooperatively interact, rise fixation.Described convex screens 30 is the protruding position of several cylinders shape that is molded on body 21 inwalls, and the corresponding spill draw-in groove 40 that holds, cooperates above-mentioned circular cylindrical projection position that forms on tubular ladder 10 external cylindrical surfaces.Described convex screens 30 is for being molded over the protruding position of several cylinders shape on tubular ladder 10 external cylindrical surfaces, and correspondingly on the inwall of body 21 form the spill draw-in groove 40 described convex screens 30 of holding, cooperate above-mentioned circular cylindrical projection position for being molded on body 21 inwalls at least one the protruding position of curved annular, and correspondence forms the spill draw-in groove 40 that holds, cooperates protruding of above-mentioned annular, curved ring-type on tubular ladder 10 external cylindrical surfaces.Described convex screens 30 is for being molded on tubular ladder 10 external cylindrical surfaces at least one the protruding position of curved annular, and the corresponding spill draw-in groove 40 that holds, cooperates protruding of above-mentioned curved annular, curved ring-type that forms on body 21 inwalls.Also can be provided with support bar 60 between the described two tubular ladders 10.

When installing and using, only need are set in the body 21 at pedal 20 two ends on the outer circumference surface of two tubular ladders 10 respectively, and make the convex screens 30 and the spill draw-in groove 40 that are molded on tubular ladder 10 external cylindrical surfaces and body 21 inwalls cooperatively interact fixing, again protective sleeve 50 is threaded on the screw thread of body 21 outer circumference surfaces, promptly finish installation, convenient and swift; During dismounting, only need to get final product by above-mentioned reverse procedure.

The embodiment of the concavo-convex fixed structure of ring-type shown in Fig. 2～4, during loading and unloading, ringwise convex screens 30 cards are set on tubular ladder 10 external cylindrical surfaces fixing in the corresponding spill draw-in groove 40 in the form of a ring on the body 21 with being molded over;

And the embodiment of the concavo-convex fixed structure embodiment of the column shown in Fig. 5～7 during loading and unloading, is set to and correspondingly on tubular ladder 10 external cylindrical surfaces is fixing in the column spill draw-in groove 40 being molded over several convex screens 30 cards that are cylindricality on the body 21;

The tubular ladder figure of embodiment shown in Fig. 8～11 for another example, in the illustrated embodiment, spill draw-in groove 40 curved ring-types correspondingly on the body 21 also form identical shaped, as to cooperate above-mentioned curved annular spill draw-in groove 40 convex screens 30.

And above-mentioned spill draw-in groove 40 can be shaped to the groove of various columns, curved annular and L shaped shape as required.Protective sleeve 50 can be screwed on the excircle flank of body 21, makes between convex screens 30 and the spill screens 40 engaging firm, prevents that it is loosening.

Like this, after people set foot on the swimming pool ladder, weight bearing was delivered on the tubular ladder 10 by pedal 20 in protective sleeve 50 fastening convex screens 30 and spill screens 40, reaches safe and reliable purpose.
