Description
Technical Field
The utility model belongs to the technical field of fixing device, concretely relates to sleeve pipe fixing device.
Background
Pre-burying and reserving are the beginning of the whole electromechanical installation project, and in the construction of a main structure of a building, a plurality of specialties are involved in the process of reserving a sleeve on a floor slab. The traditional construction process of the reserved sleeve needs to process a fixed part in advance, which consumes labor hour and materials, and the gas generated during processing also pollutes the ambient air environment.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a sleeve pipe fixing device, the device can conveniently realize fixed to the sheathed tube.
In order to solve the technical problem, the utility model discloses a technical scheme be:
a sleeve fixing device comprises a pressing plate and a pull rod, wherein a sleeve rod is sleeved outside the pull rod, one end of the sleeve rod is fixedly connected with the lower end of the pressing plate, a through hole is formed in the pressing plate, one end of the pull rod can penetrate through the through hole to extend out, and a nut is connected to the extending part of the pull rod in a threaded mode; a connecting rod mechanism is arranged between the other end of the pull rod and the other end of the sleeve rod, the connecting rod mechanism comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged with the pull rod, one end of the second connecting rod is hinged with the sleeve rod, and the other end of the first connecting rod is hinged with the other end of the second connecting rod.
The lower end of the pressing plate is provided with a convex edge.
The convex edge is conical.
The number of the connecting rod mechanisms is two.
Compared with the prior art, the utility model, the beneficial effect who has is:
the pull rod and the sleeve rod penetrate through the through hole at the upper end of the template, and then the pull rod is pulled upwards, so that the first connecting rod and the second connecting rod are folded, and the effect of fixing the template is achieved; and finally, the nut is screwed tightly, so that the pressing plate compresses the sleeve to play a role in fixing the sleeve. The device can conveniently and quickly fix the sleeve, and overcomes the defect of complex and inconvenient fixation in the prior art.
Drawings
Fig. 1 is a first perspective view of the present invention;
fig. 2 is a second perspective view of the present invention;
fig. 3 is a schematic view of the usage state of the present invention;
FIG. 4 is an enlarged view of a portion of FIG. 3 at A;
wherein: 1 is a pressing plate, 2 is a pull rod, 3 is a loop bar, 4 is a nut, 5 is a link mechanism, 51 is a first link, 52 is a second link, 6 is a convex edge, 7 is a sleeve and 8 is a template.
Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 4, a sleeve fixing device comprises a pressing plate 1 and a pull rod 2, a sleeve rod 3 is sleeved outside the pull rod 2, one end of the sleeve rod 3 is fixedly connected with the lower end of the pressing plate 1, a through hole is formed in the pressing plate 1, one end of the pull rod 2 can penetrate through the through hole and extend out, a nut 4 is connected to the extending portion of the pull rod 2 in a threaded mode, and the nut 4 is larger than the aperture of the through hole.
A link mechanism 5 is arranged between the other end of the pull rod 2 and the other end of the sleeve rod 3, the link mechanism 5 comprises a first link 51 and a second link 52, one end of the first link 51 is hinged with the pull rod 2, one end of the second link 52 is hinged with the sleeve rod 3, and the other end of the first link 51 is hinged with the other end of the second link 52; the change of the angle between the first link 51 and the second link 52 can be achieved by pulling the sleeve 7.
When in use, the lower ends of the loop bar 3 and the pull rod 2 pass through the through hole, and at the moment, the inner angle (about 180 degrees) between the first connecting rod 51 and the second connecting rod 52 is larger; then the pull rod 2 is pulled upwards, and under the action of the pull rod 2, the angle between the first connecting rod 51 and the second connecting rod 52 is reduced, so that the first connecting rod 51 and the second connecting rod 52 are larger than the holes in the template 8, and the effect of connecting with the template 8 is achieved; finally, the nut 4 is screwed, so that the pressing plate 1 presses the sleeve 7 for fixing.
Furthermore, the lower end of the pressing plate 1 is provided with a convex edge 6, and the convex edge 6 can be clamped into the sleeve 7 to play a positioning role.
Furthermore, the convex edge 6 is conical, so that the positioning effect can be improved, and the device can be suitable for the sleeve 7 with the aperture within a certain range.
Further, the link mechanism 5 is preferably provided in two, that is, one on the left and right, but may be provided in plural.
The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
