Abstract
The utility model discloses a bolt anti -disengaging structure in scaffold, scaffold include the standpipe and violently manage, outside bellied connecting portion have on the lateral wall of standpipe, first jack has on the connecting portion, violently have on the pipe with the second jack of first jack butt joint, first jack and the interpolation of second jack are equipped with the bolt, anti -disengaging structure is including the anticreep piece that is located first jack, the anticreep piece is fixed through the spring on the connecting portion, the confession has on the bolt the anticreep groove of anticreep piece embedding, the slope form that the end wall was extracted for the bolt of being convenient for under the anticreep groove, the lower extreme of bolt is described for the bolt male closed angle of being convenient for. Can prevent that the bolt breaks away from the jack owing to set up the anticreep piece, make violently the connection of pipe and standpipe more stable.
Description
Technical field
The utility model belongs to technical field of building construction, relates to latch disconnecting prevention structure in a kind of scaffold.
Background technology
Transverse tube in the existing scaffold had is connected by latch with vertical tube, but latch easily loosens disengaging, and the connection of such transverse tube and vertical tube is not just very stable, and work progress exists larger potential safety hazard.
Summary of the invention
The utility model proposes latch disconnecting prevention structure in a kind of scaffold for prior art Problems existing, and object is to prevent latch from departing from, and makes the connection of transverse tube and vertical tube more stable.
The utility model is achieved in that
Latch disconnecting prevention structure in a kind of scaffold, scaffold comprises vertical tube and transverse tube, the sidewall of described vertical tube has the connecting portion of outwardly convex, described connecting portion has the first jack, described transverse tube has the second jack with described first jack docking, latch is inserted with in described first jack and the second jack, it is characterized in that, described disconnecting prevention structure comprises the anti-drop block being positioned at the first jack, described anti-drop block is fixed on described connecting portion by spring, described latch has the anticreep groove embedded for described anti-drop block, described anticreep groove lower end wall for ease of latch extract skewed, the tip-angled shape that the lower end of described latch is inserted for ease of latch.
Preferably, described anti-drop block is square, described latch has the square holddown groove of the confession described anti-drop block embedding be communicated with described anticreep groove.
Latch disconnecting prevention structure in a kind of scaffold provided by the utility model, can prevent latch from departing from jack owing to being provided with anti-drop block, make the connection of transverse tube and vertical tube more stable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model disconnecting prevention structure.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Present embodiments provide latch disconnecting prevention structure in a kind of scaffold, as shown in Figure 1, scaffold comprises vertical tube 100 and transverse tube 200, the sidewall of described vertical tube 100 has the connecting portion 110 of outwardly convex, described connecting portion 110 has the first jack, described transverse tube 200 has the second jack with described first jack docking, latch 300 is inserted with in described first jack and the second jack, described disconnecting prevention structure comprises the anti-drop block 111 being positioned at the first jack, described anti-drop block 111 is fixed on described connecting portion 110 by spring 112, described latch 300 has the anticreep groove 310 embedded for described anti-drop block 111, described anticreep groove 310 lower end wall for ease of latch 300 extract skewed, the tip-angled shape that the lower end of described latch 300 is inserted for ease of latch 300.
Being built by a large amount of vertical tubes 100 and transverse tube 200 of scaffold.During installation, first jack and the second jack are aimed at, latch 300 is inserted the second jack until through the first jack, in insertion process, when the ends contact of latch 300 tip-angled shape is after anti-drop block 111, extruding anti-drop block 111 impels spring 112 to compress, and after latch 300 insertion puts in place, spring 112 bounce-back makes anti-drop block 111 embed anticreep groove 310.During dismounting, reverse operating.
Anti-drop block 111 can be hemispherical.Preferably, described anti-drop block 111 is square, described latch 300 has the square holddown groove 320 of confession described anti-drop block 111 embedding be communicated with described anticreep groove 310.During installation, put in place when latch 300 inserts, after anti-drop block 111 embeds anticreep groove 310, rotate latch 300, anti-drop block 111 is made to embed in holddown groove 320, because holddown groove 320 lower end wall is not skewed, when latch 300 does not rotate, latch 300 cannot be extracted under the obstruction of anti-drop block 111, further ensures the reliability and stability that latch 300 connects.During dismounting, latch 300 will be rotated, and make anti-drop block 111 enter anticreep groove 310 and then extract.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or improved, and all these increases and decreases, replacement, conversion or the technical scheme after improving, all should belong to the protection domain of the utility model claims.
Claims (2)
1. latch disconnecting prevention structure in a scaffold, scaffold comprises vertical tube and transverse tube, the sidewall of described vertical tube has the connecting portion of outwardly convex, described connecting portion has the first jack, described transverse tube has the second jack with described first jack docking, latch is inserted with in described first jack and the second jack, it is characterized in that, described disconnecting prevention structure comprises the anti-drop block being positioned at the first jack, described anti-drop block is fixed on described connecting portion by spring, described latch has the anticreep groove embedded for described anti-drop block, described anticreep groove lower end wall for ease of latch extract skewed, the tip-angled shape that the lower end of described latch is inserted for ease of latch.
2. disconnecting prevention structure according to claim 1, is characterized in that, described anti-drop block is square, described latch has the square holddown groove of the confession described anti-drop block embedding be communicated with described anticreep groove.
