Abstract
The utility model discloses a guard bar connecting device for safety paling of bouncing bed, belonging to the manufacturing technology field of the bouncing bed component of the exercise apparatus. The guard bar connecting device for safety paling of bouncing bed mainly comprises a guard bar (1), a peripherical frame (6) with a short branch pipe (6) at the lower part, a foot rack (2) inserted in the short branch pipe (5). The foot rack (2) and the guard bar (1) are respectively provided with 2-4 anchor holes, and the anchor holes are fixedly connected by 2-4 anchor bolts. The connecting point of each anchor bolt (3) between the foot rack (2) and the guard bar (1) is also provided with a heel block (4). The utility model makes the guard bar of the bouncing bed and the foot rack be combined rapidly and firmly by adopting the 2-4 anchor bolts. The design is reasonable, and the combined strength of the guard bar for safety paling of bouncing bed can be improved effectively. The safety paling can be positioned better, and the installation and manufacture is made quicker and more convenient. At the same time, a heel block is increased between the guard bar and the foot rack, the point stress is changed to the surface stress, and therefore, the stress surface is increased. The combined force of the guard bar and the foot rack is improved further.
Description
Technical field
The utility model relates to a kind of trampoline safety fences guard bar jockey, belongs to the manufacturing technology field of trampoline assembly in the sports apparatus.
Background technology
Trampoline places a plurality of flexible members of circular frame inside to tighten the formations such as spring face that the back is formed generally by the synthetic circular frame of a plurality of steel pipe, and spring face constitutes a location height by a plurality of foot rests.In order to ensure use that can safety, the general safe fences that is higher than trampoline that is provided with in the neighboring, this fences comprises guard bar and the protection network that circumferentially twines.The user can arbitrarily bounce like this, avoids unexpected bullet to fall, and damages.
Have guard bar now and mainly contain the U-shaped folder being connected of foot rest and be welded to connect two kinds of versions.United States Patent (USP) provides a kind of safe fences of trampoline for 6261207B1 number, is to adopt a plurality of U-shaped folders that the joint of fender rod, foot rest, peripheral frame is connected, and its joint construction quite expends man-hour, cost; And the direction of engagement of fender rod and foot rest be subjected to force direction very undesirable, conjugation grade is obviously not enough; Simultaneously can't be with the firm location of guard bar, be easy to generate and rock, skid or make the impaired phenomenon in junction.Chinese patent provides a kind of trampoline safety fences guard bar joint construction for No. 2571421, be that peripheral frame, foot rest and guard bar are welded to connect, because fender rod, foot rest, peripheral frame all are hollow tube, therefore the problem of burning appears in the joint construction of welding easily in manufacturing process, produce the impaired or material in junction and scrap, also influenced the intensity that engages simultaneously greatly.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the bond strength of trampoline safety fences guard bar, better the safety fences is positioned, and makes it that making trampoline safety fences guard bar jockey more fast and easily is installed.
The utility model is a trampoline safety fences guard bar jockey, comprise guard bar, the peripheral frame of the short arm of bottom band is embedded in the foot rest of short arm bottom, it is characterized in that offering 2～4 anchor hole respectively on foot rest and the guard bar and fixedlying connected with 2～4 crab-bolts.
Junction in the per pass crab-bolt between described foot rest and the guard bar also can be provided with cushion block, to guarantee the bond strength between foot rest and the guard bar.
Described peripheral frame, foot rest, guard bar can be the hollow circular tube of deciding diameter.Described foot rest can be U-shaped, W shape or V-arrangement pipe.
Described cushion block can adopt materials such as aluminium alloy, cast iron or plastic, rubber.
2～4 crab-bolts of the utility model employing make the guard bar and foot rest firm the engaging fast of trampoline, and are reasonable in design, can effectively improve the bond strength of trampoline safety fences guard bar, better the safety fences positioned, and make its installation make more efficient and convenient.Avoided the loaded down with trivial details operation of U type folder, and be easy to generate and rock, skid or make the impaired phenomenon in junction; Also overcome to be welded to connect and easily burnt and the junction is impaired or material is scrapped problem.Simultaneously, increase by a cushion block between guard bar and the foot rest, stressedly transfer face to by point and increase stress surface, further improved the engaging force of guard bar and foot rest thereby make.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the decomposition chart of the utility model connecting portion.
Among the figure, 1 is guard bar, and 2 is foot rest, and 3 is crab-bolt, and 4 is cushion block, and 5 are short arm, and 6 is peripheral frame, and 7 are spring face frame, and 8 are spring face, and 9 is flexible member.
The specific embodiment
The utility model is mainly by guard bar 1, the peripheral frame 6 of the short arm 5 of bottom band, be embedded in foot rest 2 formations such as grade of short arm 5 bottoms, offer 2～4 anchor hole on foot rest 2 and the guard bar 1 respectively and fixedly connected with 2～4 crab-bolts 3, the junction in per pass crab-bolt 3 between foot rest 2 and the guard bar 1 also is provided with cushion block 4.
During installation, earlier with 8 peripheral frame 6 chimeric circles that connect into that have short arm 5, foot rest 2 is embedded in short arm 5 bottoms, spread the spring face 8 of band spring face frame 7 then out, with flexible member 9 peripheral frame 6 is connected with spring face frame 7, on flexible member 9, lay protection pad, promptly constitute trampoline with location height spring face 8.Guard bar 1 is fixedlyed connected with cushion block 4 with crab-bolt 3, the required safe fences of height winding according to guard bar 1 can use.
Claims (5)
1, a kind of trampoline safety fences guard bar jockey, comprise guard bar (1), the peripheral frame (6) of the short arm of bottom band (5), be embedded in the foot rest (2) of short arm (5) bottom, it is characterized in that offering 2～4 anchor hole on foot rest (2) and the guard bar (1) respectively and fixedlying connected with 2～4 crab-bolts (3).
