Bracing or strutting arrangement

Technical field

The utility model relates to a kind of bracing or strutting arrangement, and this bracing or strutting arrangement mainly is to be used to be combined into Foldable scaffold or fold-away stairway etc.

Background technology

Owing to combination, the dismounting of Foldable scaffold or fold-away stairway are very convenient, people often use when ascend operation.The Foldable scaffold or the fold-away stairway overwhelming majority utilize bracing or strutting arrangement to be combined to form at present, this support device structure is: two parallel standpipes are arranged, between two standpipes, be connected with the transverse tube that is parallel to each other, be connected for rotating shaft between the termination of transverse tube and the standpipe, between two standpipes, be connected with inclined tube, be connected for rotating shaft between the two ends of inclined tube and the standpipe, for the integrated support device can be folded, the joint is installed on inclined tube, the inclined tube that is the both sides, joint can rotate folding with respect to joint, cause two standpipes to merging together, each transverse tube two ends rotates with respect to standpipe simultaneously, makes the bracing or strutting arrangement foldable integral.The bracing or strutting arrangement of this structure, following shortcoming is arranged: owing on the inclined tube joint is installed, the effect in joint is when whole inclined tube is in the straight tube state, and the joint is in the block state, promptly keep the inclined tube of both sides, joint to be on the same straight line, supporting standpipe and each transverse tube of launching; When folding, manually remove the backstop state in joint, inclined tube just can be transferred at joint, makes the integrated support device reach folding purpose to merging together; Shared space, joint has increased the distance between inclined tube and each transverse tube, and promptly inclined tube can not rely on transverse tube, has influenced the stability of whole bracing or strutting arrangement, facts have proved, the big more bracing or strutting arrangement of the distance between inclined tube and the transverse tube is unstable more.

Summary of the invention

The purpose of this utility model provides a kind of gap between inclined tube and the transverse tube, bracing or strutting arrangement of increase resistance to overturning eliminated, and overcomes the deficiencies in the prior art.

Bracing or strutting arrangement of the present utility model, it comprises two standpipes, between two standpipes, be connected with the transverse tube that is parallel to each other, be connected for rotating shaft between the termination of transverse tube and the standpipe, between two standpipes, be connected with inclined tube, one end of described inclined tube is connected with wherein a standpipe rotating shaft, is connected for hook between the other end of inclined tube and another root standpipe.

Bracing or strutting arrangement of the present utility model, wherein said hook is connected to: be fixedly connected with bearing pin on the side of standpipe, the termination of described inclined tube is fixedly connected with hook; Described hook comprises that being fixedly connected with endoporus with the inclined tube termination is half poroid stay hook, stay hook is a double-layer structure, be provided with swivel hook in the gap in the middle of it, be rotationally connected by rotating shaft between one end of swivel hook and the stay hook, press spring and the catch pawl on the other end of swivel hook is pressed against on the port inside wall of inclined tube being provided with on the turning cylinder, the endoporus that swivel hook and stay hook are constituted is between whole hole and half hole, is connected to paw on the swivel hook.

Bracing or strutting arrangement of the present utility model, the termination of wherein said turning cylinder is provided with baffle ring.

Bracing or strutting arrangement of the present utility model, owing to be connected for rotating shaft between an end of inclined tube and the standpipe, be connected for hook between the other end of inclined tube and another standpipe, when folding bracing or strutting arrangement as needs, can remove being connected between inclined tube and the standpipe at the hook place, inclined tube is rotated along the other end to be overlapped with standpipe, finally reach the purpose of folding bracing or strutting arrangement, on inclined tube, there is not the joint, can make inclined tube rely on transverse tube, eliminate the gap that exists between the inclined tube and transverse tube in the prior art, improved the resistance to overturning of bracing or strutting arrangement, utilized this device to be combined into scaffold or staircase is safer reliable.

Fig. 1 is that bracing or strutting arrangement launches schematic diagram in the utility model specific embodiment;

Fig. 2 is the folding schematic diagram of bracing or strutting arrangement in the utility model specific embodiment;

Fig. 3 is the structural representation of hook shown in Figure 1;

Fig. 4 is an A-A sectional schematic diagram shown in Figure 3.

The specific embodiment

As shown in Figure 1, 2: 1 is standpipe, two standpipes 1 be arranged in parallel, the transverse tube 2 that is parallel to each other is arranged between two standpipes 1, be connected for rotary shaft between the two ends of transverse tube 2 and the standpipe 1, concrete structure is to be welded with on standpipe 1, termination at transverse tube is welded with, and is processed with pin-and-hole and is installed with on standpipe 1 joint and the transverse tube connector to be connected bearing pin, makes transverse tube 2 rotatable with respect to standpipe 1.

3 is inclined tube, one end of inclined tube 3 with wherein between standpipe 1 rotating shaft be connected, promptly on the side of standpipe 1, be welded with the inclined tube connecting axle, the termination of inclined tube 3 is welded with the connector of band pin-and-hole and is enclosed within on the inclined tube connecting axle, in order to prevent to come off, be welded with baffle ring in the termination of inclined tube connecting axle.

Shown in Fig. 1,2,3,4: the other end at inclined tube 3 is connected to hook 4, and concrete structure is to be welded with stay hook 7 in the end of inclined tube 3, and the endoporus of stay hook 7 is partly poroid.Stay hook 7 is a double-layer structure, be provided with swivel hook 6 in the gap in the middle of it, be connected by rotating shaft 9 between the front end of swivel hook 6 and the stay hook 7, be connected with catch pawl 10 and the paw 11 that is integrative-structure with swivel hook 6 at the other end of swivel hook 6, catch pawl 10 is positioned at inclined tube 3 port inboards.Torque spring 8 is housed in rotating shaft 9, and torque spring 8 presses swivel hook 6, and the catch pawl 10 on the swivel hook 6 is relied on the inside wall of inclined tube 3 ports, and swivel hook 6 is in many semicircle shapes with the endoporus 12 that stay hook 7 forms, and promptly leaves opening 13.On the side of standpipe 1, be welded with bearing pin 5 and match, be welded with baffle ring, prevent to link up with 4 axially coming off along bearing pin 5 in the termination of bearing pin 5 with many semicircle shapes endoporus 12.
