Description

A kind of sit-up device

Technical field

The utility model relates to a kind of sit-up device, belongs to the strong material field of physical culture.

Background technology

Chinese patent ZL201120025017.4 discloses a kind of sit-ups band, formed by loose-leaf, hook, band hook, sit-ups band, hook A and band hook B are installed respectively at the two ends of sit-ups band, A articulates hook A at the band hook, and hook A and loose-leaf A or bed hook are hinged, distribution loose-leaf hole A on loose-leaf A, B articulates hook B at the band hook, at loose-leaf B distribution loose-leaf hole B, at the bed hook installing hole is arranged, at the sit-ups band length adjusting button is arranged; This sit-ups band can be installed in bed, auxiliary sit-ups, however hook structure makes the sit-ups band firm inadequately with being connected of bed, and the structure of fixed leg is not easy to regulate, and causes use to make things convenient for inadequately.

The utility model content

The utility model provides a kind of sit-up device, has solved the problem that hook is not firm and the inconvenience of shank fixed band is regulated.

Technical scheme of the present invention is as described below.

A kind of sit-up device comprises that the sit-ups band of two same configuration, sit-ups band comprise that catching groove, screw, clasp, contiguous block, a mouthful word are buckled, the thread gluing fixed band; Catching groove is provided with screw hole and screw, and catching groove is connected with contiguous block by clasp, and contiguous block links by the mouth word each other and connects, and the thread gluing fixed band is connected with contiguous block by a mouthful word button.

Described catching groove is provided with on the same one side of screw hole and screw and also is provided with bail, and bail is provided with screw thread, and bail closely is connected with catching groove by screw thread.

The opposite that described catching groove is provided with screw hole and screw place face is provided with fixed cap, and fixed cap is tightened on the screw root with the ring nail and closely is connected with catching groove.

Described mouthful of word button comprises stationary pipes and buckle, and buckle injects in the stationary pipes.

Compared with prior art, the technique effect that the utility model reaches is: contiguous block of the present utility model is more convenient for regulating with dismountable mouthful of word button and is connected length, use the design of fixed cap or bail the fixing of sit-up device of being more convenient for, it is simple in structure, easy to operate, safe and reliable, be easy to carry about with one, can stably be fixed under the mattress, on bed board or the bed beam, the carrying out of effectively auxiliary sit-up movement.

The specific embodiment

In order to deepen that the utility model is understood, the present invention is described in further detail below in conjunction with embodiment, and this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.

Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the catching groove Facad structure figure of structure correspondence shown in Figure 1, and Fig. 3 is the side view of Fig. 2, and Fig. 4 is the fixed cap structural representation.As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is a kind of sit-up device, comprises that catching groove 1, screw 2, clasp 5, a mouthful word buckle 6, thread gluing connecting band 7, contiguous block 8; Catching groove 1 is provided with screw hole and screw 2, also is provided with fixed cap 4 on the catching groove 1; One end of clasp 5 passes contiguous block 8, and the other end is buckled on the fixed cap 4; Be connected by dismountable mouthful of word button 6 between contiguous block 8 and the contiguous block 8, thread gluing connecting band 7 also is connected with contiguous block 8 by a mouthful word button 6.Fig. 4 is the fixed cap structural representation, and as shown in Figure 4, fixed cap 4 closely is fastened on the catching groove 1 by screw root 12 and ring nail 13, when clasp 5 is buckled on the fixed cap 4, as long as after fixed cap 4 screwed off from screw root 12, clasp 5 is enclosed within on the ring nail 13, fixed cap 4 is screwed on get final product again.Fig. 9 is thread gluing connecting band structural representation, and as shown in Figure 9, the thread gluing fixed band is provided with thread gluing 9, fixed leg that can be firm.Figure 10 is a mouthful word buckle structure schematic diagram, as shown in figure 10, a mouthful word button 6 is made up of stationary pipes 10 and buckle 11, and buckle 11 injects in the stationary pipes 10, increase or reduce contiguous block 8 at needs and regulate when connecting length, can dismantle a mouthful word button 6 by extracting or inject buckle.When catching groove fastens under the mattress or during the bed beam, the screw 2 that can tighten catching groove 1 side fixes catching groove 1, then clasp 5 is buckled on the fixed cap 4, namely obtains of the present utility model a kind of structural representation as shown in Figure 1.
