Description
Technical Field
The utility model relates to a valve gland ha fu formula telescopic joint that takes precautions against earthquakes belongs to telescopic joint technical field.
Background
According to the valve gland type shockproof expansion piece shown by the retrieved Chinese publication No. CN201320014459.8, the upper cover and the lower cover of the expansion piece are designed in a split mode and are fixed together only when being installed, so that the upper cover and the lower cover are possibly disordered during transportation, the upper cover and the lower cover with different diameters are not matched during installation, fixing bolts need to be symmetrically locked at two sides during installation of the expansion piece, a plurality of nuts and matched bolts are used, time is consumed for installation and removal, and the working efficiency is low.
Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: the utility model provides a valve gland ha fu type telescopic joint that takes precautions against earthquakes, it has solved upper cover and lower cover and can appear depositing the confusion to installation and demolish all harder problem.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
valve gland huff formula telescopic joint that takes precautions against earthquakes, including flange, lower cover and upper cover, the coaxial fixed connection of terminal surface of flange and lower cover, the both sides end of lower cover and upper cover is equallyd divide first connecting block of fixedly connected with and second connecting block, two a plurality of screws, two have all been seted up on the first connecting block the second connecting block passes through the hinge and rotates the connection, one of them fixedly connected with latch segment, another on the closed terminal surface of second connecting block the draw-in groove has been seted up on the closed terminal surface of second connecting block, works as when lower cover and upper cover are closed, the latch segment inserts in the draw-in groove.
As a preferred example, the inner walls of the lower cover and the upper cover are fixedly connected with a plurality of semicircular hoops, and when the lower cover and the upper cover are closed, two groups of semicircular hoops are combined into a circular hoop.
As a preferred example, the number of the semicircular clips in each group is at least three.
As a preferred example, a reinforcing rib is fixedly connected between one group of the first connecting block and the lower cover, and a reinforcing rib is fixedly connected between the other group of the first connecting block and the upper cover.
The utility model has the advantages that:
1. the utility model discloses adopt the integral type design with upper cover and lower cover, make upper cover and lower cover can not appear depositing the confusion and lead to the size to mismatch in the transportation through the installation form of hinge.
2. Because the one end of this telescopic joint passes through hinged joint, only need can realize the fixed of this telescopic joint and seal at the other end installation fixing bolt of hinge, relative traditional telescopic joint, can reduce half installation or demolish the time.
3. Hinge spare is when closing, because the restriction of self structure, has slit or two and rotates and do not have pressure in hinge department, the utility model discloses a setting of latch segment and draw-in groove compresses tightly the sealed pad of follow-up installation for this telescopic joint is good at the leakproofness of hinge department.
Drawings
Fig. 1 is a perspective view of the present invention;
FIG. 2 is a schematic structural view of portion A of FIG. 1;
fig. 3 is a front view of the present invention.
In the figure: flange 1, first connecting block 2, lower cover 3, semicircle clamp 4, upper cover 5, latch segment 6, second connecting block 7, draw-in groove 8.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-3, shockproof telescopic joint of valve gland huff formula, including flange 1, lower cover 3 and upper cover 5, the coaxial fixed connection of terminal surface of flange 1 and lower cover 3, first connecting block 2 of difference fixedly connected with and second connecting block 7 are equallyd divide to the both sides end of lower cover 3 and upper cover 5, a plurality of screws have all been seted up on two first connecting blocks 2, two second connecting blocks 7 rotate through the hinge and connect, fixedly connected with latch segment 6 on the closed terminal surface of one of them second connecting block 7, draw-in groove 8 has been seted up on the closed terminal surface of another second connecting block 7, when lower cover 3 and upper cover 5 are closed, latch segment 6 inserts in the draw-in groove 8.
Adopt above-mentioned scheme, lower cover 3 and flange 1 are fixed, rotate through the hinge connection between lower cover 3 and the upper cover 5 simultaneously for this telescopic joint convenient to carry, and can reduce the installation and demolish the time of using, holistic leakproofness is good simultaneously.
The equal a plurality of semicircle clamps 4 of the equal fixedly connected with of inner wall of lower cover 3 and upper cover 5, when lower cover 3 and upper cover 5 closed, two sets of semicircle clamps 4 make up into circular clamp, and the quantity of every group semicircle clamp 4 is three at least.
By adopting the scheme, the sealing rings are embedded between the semicircular hoops 4, so that the sealing rings are stable to mount, cannot deviate and have good sealing performance.
Fixedly connected with strengthening rib between one set of first connecting block 2 and second connecting block 7 and lower cover 3, also fixedly connected with strengthening rib between another set of first connecting block 2 and second connecting block 7 and upper cover 5.
By adopting the scheme, the mechanical strength of the lower cover 3 and the upper cover 5 can be effectively increased.
The working principle is as follows: when using, select the telescopic joint of adaptation size, flange 1 is installed on the exit of equipment or water pump, the inner wall of lower cover 3 and upper cover 5 all is provided with sealed the pad, lower cover 3 cup joints on the water pipe this moment, then directly upset upper cover 5, make upper cover 5 also cup joint on the water pipe, lower cover 3 and upper cover 5 make up into circular sleeve pipe this moment, utilize fixing bolt locking lower cover 3 and upper cover 5, latch segment 6 inserts in draw-in groove 8 along with the removal of upper cover 5, and go into in draw-in groove 8 with sealed pad card, make the leakproofness between the two halves sealed pad good.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above.
