Abstract
The utility model discloses a composite suspended ladder. The composite suspended ladder comprises a low platform, a high platform and a suspended ladder body connected between the lower platform and the high platform. The suspended ladder body is a plastic suspended ladder body. The lower end of the plastic suspended ladder body is provided with a first locating step which is connected with a platform top of the low platform in a suspended mode and matched with the platform top of the low platform. The upper end of the plastic suspended ladder body is provided with a second locating step which is connected with a platform top of the high platform in a suspended mode and matched with the platform top of the high platform. The second locating step comprises a second upward protruding portion and a second laterally attaching portion which form an L shape. The second laterally attaching portion and the side wall of the platform top of the high platform are respectively provided with a second threaded connection hole, wherein the second threaded connection holes correspond to each other and are fixedly connected through a second fastening bolt. The composite suspended ladder has the advantages that the structural arrangement is reasonable, the supporting effect is stable and reliable, the children injuries caused by contact and collision can be reduced, and the service life is long.
Description
Technical field
The utility model relates to a kind of amusement of children facility, specifically refers to the unsettled ladder of a kind of combined type.
Background technology
Generally all supporting in existing amusement of children facility have a unsettled ladder, and the platform that unsettled ladder does not wait two height links up, and with convenient for children, walks up and down and climbs.The structure of existing unsettled ladder is all generally to adopt single-layer metal plate (being generally iron plate) panel beating to be made.Although this traditional unsettled ladder structural strength is higher, but has following shortcoming:
(1) children, in climbing process, can often occur falling down, and the unsettled ladder that the single-layer metal plate that hardness is higher is made into lacks buffering, often make children's skin occur becoming silted up blue or green because falling down contact;
(2) normal children's recreation facility is all placed in outdoorly, and this traditional unsettled ladder gets rusty easily, and application life is shorter.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provides a kind of structure to arrange rationally, and support effect is reliable and stable, and can reduce the injury of contact-impact to children, the unsettled ladder of a kind of combined type of long service life.
For achieving the above object, the technical solution of the utility model is to include low, high platform and be connected in low, unsettled ladder between high platform, described low includes low platen and low support bar, described high platform includes high platform platen and high platform support bar, described unsettled ladder is the unsettled ladders of plastics, on the bottom of the unsettled ladder of these plastics, be provided with low platen and articulate the first positioning step coordinating, this first positioning step includes mutually the first upper convex portion and the first side subsides portion that is " L " type, the first described side subsides portion is provided with the first corresponding threaded connection hole with on the sidewall of low platen, the two is fixedly connected by the first fastening bolt, on the upper end of the described unsettled ladder of plastics, be provided with high platform platen and articulate the second positioning step coordinating, this second positioning step includes mutually the second upper convex portion and the second side subsides portion that is " L " type, the second described side subsides portion is provided with the second corresponding threaded connection hole with on the sidewall of high platform platen, the two is fixedly connected by the second fastening bolt.
By this setting, unsettled ladder is adopted to the unsettled ladder of plastics, utilize elasticity and the buffer capacity of plastics itself, can avoid the injury of contact-impact to children, and long service life, in addition, this setting, upper end and bottom at the unsettled ladder of plastics all arrange the first positioning step and the second positioning step, articulated and be supported on low platen and Gao Tai platen, and then utilize fastening bolt to carry out being fixedly connected with of the unsettled ladder of plastics and high platform platen and low platen, so, the first upper convex portion and the second upper convex portion can be shared support to the longitudinal stress of fastening bolt, ensure stability and reliability that fastening bolt connects, ensured the normal use of equipment.
Further arrange is that the bottom surface of the described unsettled ladder of plastics is provided with the first bolt head embedded slot with respect to the first threaded connection hole inner end positions of the first side subsides portion.Further arrange is that the bottom surface of the described unsettled ladder of plastics is provided with the second bolt head embedded slot with respect to the second threaded connection hole inner end positions of the second side subsides portion.By this setting, the layout of the first bolt head embedded slot and the second bolt head embedded slot, not only facilitate the bolt head of fastening bolt to shelve, and bolt head is placed in this first bolt head embedded slot or the second bolt head embedded slot, can also itself carry out strength support to the unsettled ladder of plastics, improve bonding strength of the present utility model and stability.
Further arranging is to be provided with multistage unsettled halfpace rank on the described unsettled ladder of plastics, is provided with the anti-skidding protruding ball of a plurality of massages and the anti-skidding convex tendon of massage on the upper surface on these unsettled halfpace rank.By this setting, the anti-skidding protruding ball of described massage, when children walk, can be massaged children's sole, and prevents that children from slipping.
The bottom that corresponding each the unsettled halfpace rank, bottom surface that are the described unsettled ladder of plastics are further set is provided with the indent arch groove of cross section ovalisation.By this setting, this indent arch groove can effectively support unsettled halfpace rank, has improved its resistance to compression ability to bear.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
