Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Please refer to fig. 1, fig. 1 is a schematic view of an overall structure of a conveniently installed hold-down bolt for an earthquake-proof support hanger of the present invention.
As shown in fig. 1, the utility model discloses a pressure bolt convenient to installation that antidetonation gallows was used, including U type channel-section steel 1, channel-section steel hasp 2 and hex bolts 3, channel-section steel hasp 2 is located U type channel-section steel 1, hex bolts 3 connects in channel-section steel hasp 2 soon, hex bolts 3 includes relative head end 31 and tail end 32, tail end 32 a body coupling has outer hex bolts head 33, hex bolts 3 middle part sets up through-hole 34, the extending direction of through-hole 34 is the same with hex bolts 3's extending direction, the center pin of through-hole 34 is the same with hex bolts 3's center pin, movably wear to be equipped with connecting rod 4 in the through-hole 34, wear out in the both ends outside at through-hole 34 at the both ends of connecting rod 4, connecting rod 4 is located the outer one end body coupling of head end 31 and has compressing tightly piece 5, connecting rod 4 is located the.
In one embodiment, the pressing sheet 5 is used for being clamped outside the screw rod 7, the screw rod 7 is limited below the pressing sheet 5, the screw rod 7 is prevented from sliding below the pressing bolt, the outer diameters of the pressing sheet 5 and the limiting block 6 are larger than the inner diameter of the through hole 34, so that the connecting rod 4 is ensured to be in the hexagon bolt 3, the pressing sheet 5 and the pressing bolt are ensured to be always in an integrated structure, the pressing sheet 5 and the pressing bolt can be mutually limited, and the structure is prevented from being loose; and connecting rod 4 can be at 34 internal rotations of through-hole, and pressing blade 5 and stopper 6 all with connecting rod 4 fixed connection, so, under the fixed circumstances of pressing blade 5, connecting rod 4 is also fixed with stopper 6, consequently, after pressing blade 5 seted up on lead screw 7 in U type channel-section steel 1, rotatory hex bolts 3, pressing blade 5 can not rotate this moment, so, can be under the fixed circumstances of pressing blade 5, rotatory hex bolts 3, compress tightly lead screw 7 until hex bolts 3.
In an embodiment, the length of the connecting rod 4 is greater than that of the hexagon bolt 3, so that the pressing piece 5 can be pulled upwards by pulling the limiting block 6 at the outer side under the condition that the pressing bolt is not locked, and thus the pressing piece 5 can be adjusted when the pressing bolt is not locked.
Preferably, the pressing sheet 5 is far away from the one end of the connecting rod 4 and is an inwards concave arc-shaped groove 51, so that the pressing sheet 5 can clamp the screw rod 7 more conveniently, the screw rod 7 is prevented from sliding out of the pressing sheet 5, and the pressing sheet can be suitable for screw rods 7 of different sizes.
Preferably, support plates 52 are integrally connected to both ends of the groove 51 in a horizontal arrangement. The setting of backup pad 52 for support in lead screw 7 both sides when lead screw 7 is thinner, prevent that clamp bolt from excessively flattening lead screw 7, provide the appearance space for lead screw 7, at this moment, the diameter of lead screw 7 that clamp bolt is suitable for needs to be greater than the hunch height of recess 51, so can guarantee that clamp plate 5 compresses tightly lead screw 7 smoothly.
Preferably, the joint of the lower surface of the support plate 52 and the lower surface of the groove 51 of the pressing piece 5 is provided with a round corner 53. The connection is ensured to be smooth, and the outer side surface of the screw rod 7 is prevented from being scratched.
Preferably, one side that compressing tablet 5 and connecting rod 4 are connected is horizontal plane 54, and horizontal plane 54 butts against with head end 31, guarantees that compressing tablet 5 is enough big with the head end 31 area of contact of hex bolts 3, and the atress is more even, and it is more compact to press.
Preferably, the stopper 6 has a cylindrical shape so that the outer surface thereof is smooth, thereby facilitating the rotation of the hexagon bolt 3.
Preferably, the outer diameter of the stopper 6 is smaller than the diameter of the inscribed circle of the external hexagonal screw head 33, so that the stopper 6 is prevented from greatly hindering the rotation of the hexagonal bolt 3.
When the utility model is used, the hold-down bolt is firstly installed in the U-shaped channel steel 1, then the inner bent edge of the U-shaped channel steel 1 is embedded in the groove on the channel steel lock catch 2, then the hexagon bolt 3 is rotated, at the moment, under the action of gravity, the hold-down piece 5 drives the connecting pipe to be suspended below the hexagon bolt 3, the limiting block 6 is pressed above the hexagon bolt 3, thereby preventing the hold-down piece 5 and the connecting rod 4 from dropping, until the hold-down piece 5 contacts with the lead screw 7 to be pressed and fixed, at the moment, the limiting block 6 is rotated to drive the hold-down piece 5 to rotate until the groove 51 of the hold-down piece 5 is arranged above the lead screw 7, then the limiting block 6 is pressed down to enable the limiting block 6 to abut against the tail end 32 of the hexagon bolt 3, then the hexagon bolt 3 is continuously screwed, at the moment, because of the mutual limiting function of the lead screw 7 and the, so operate, screw until hex bolts 3, firmly press on the upper surface of holding down piece 5, make holding down piece 5 tightly pressed from both sides tightly between hex bolts 3 and lead screw 7, lead screw 7 is firmly crowded in the centre by the bottom surface of holding down piece 5 and U type channel steel 1 again, realizes effectively fixing of lead screw 7, and can prevent that lead screw 7 surface from being frayed.
From the above, the utility model discloses a pressing bolt convenient to install for antidetonation gallows, the setting of compact heap, can utilize the compact heap to clamp in the lead screw outside when mutual installation between lead screw, channel-section steel and pressing bolt, thereby prevent the lead screw from sliding, then rotatory hexagon bolt, when hexagon bolt compresses tightly, it is directly compressed tightly on the compact heap, and when hexagon bolt screwed, the compact heap clamps in the lead screw outside, the connecting rod links firmly with the stopper, therefore, can not drive the connecting rod rotation when hexagon bolt rotates, thereby guarantee that can not produce relative movement between compact heap and the lead screw, effectively protect the lead screw, therefore, hexagon bolt only produces the friction with the compact heap, thereby can effectively protect the lead screw surface not damaged, the life of extension lead screw; the pressing piece is arc-shaped and is covered on the screw rod, so that the screw rod can be prevented from sliding under pressure, and the fixation is better; the upper surface of compressing tightly the piece has effectively increased the area of contact of hex bolts with compressing tightly the piece for the plane to make the pressurized more even. Therefore, the utility model has the characteristics of the installation of being convenient for avoids the lead screw to skid, and can effectively protect the lead screw not by the scratch, extension lead screw life and the cyclic utilization of being convenient for.
