Specific embodiment:
Round (attached drawing 1) or oval (attached drawing 2) is made in steel pipe or four sides are orthodrome, and quadrangle is small arc-shaped or obtuse angle
Square circular (attached drawing 3) outline border of the steel pipe frame (1) as wooden bed frame strung with crisscross coir ropes bed, be installed with the guy wire intersected in length and breadth on steel pipe frame (1)
(2), the tensile strength of guy wire (2) is very strong, and elongation is very low, wears again very tight, wooden bed frame strung with crisscross coir ropes bed can be made strong enough, light and handy steel pipe
Why frame (1) can bear the pulling force of taut very tight guy wire (2), we analyze the stress condition of steel pipe frame: for
Narration is convenient, and round wooden bed frame strung with crisscross coir ropes bed is divided into the right and left and upper and lower both sides as rectangular wooden bed frame strung with crisscross coir ropes bed by we, when direction
When the pulling force of guy wire (2) is applied to the right and left of steel pipe frame (1) and them is made to generate the trend to be furthered, because of steel pipe frame
(1) the right and left is each one section of opposite arc, so they generate the trend for being straightened and elongating, steel pipe frame (1) simultaneously
Both sides up and down just necessarily lead to and be shortened and push away remote trend, and at this moment both sides are also just being born from another direction up and down
The pulling force of guy wire (2) also makes them generate the trend to be furthered, they are also each one section of opposite arc, so they are also same
When generate the trend that is straightened and elongates, it is impossible to be shortened and push away it is remote, so the drawing of the guy wire of circle wooden bed frame strung with crisscross coir ropes bed both direction
Power is cancelled out each other, and is made light and handy steel pipe frame (1) that can bear the pulling force of taut very tight guy wire, is kept wooden bed frame strung with crisscross coir ropes bed strong enough.In
It is that determine the round main production quality of wooden bed frame strung with crisscross coir ropes bed is exactly how guy wire to be worn enough to tight.
Being described below after the method and guy wire for easily guy wire being worn very tight on steel pipe frame (1) with the passing of time relax makes to stretch tight
Restore tight method:
Easily the method 1 that guy wire is worn very tight: being connected to and steel pipe in the predetermined wire rope handling spot welding of steel pipe frame (1) inner ring
The perpendicular small steel pipe (10) of frame plane is used as guy line pile, and there is one section of internal screw thread (18) in the upper end of small steel pipe (10), wears guy wire
When, a tension hook is first screwed in the small steel pipe (10) of each of top and the left side, is paid attention to that bottom cannot be screwed into, to be stayed a circle spiral shell
Line surplus.
Tension hook is made of arc section (5) and its extended segment (4) and screw rod (6), the extension of arc section (5) and one end
Section (4) is made of the round steel equal with small steel pipe (10) outer diameter, surface polishing, and screw rod (6) cooperates the internal screw thread of small steel pipe (10)
(18) it is connected with the other end of arc section (5) at about 100 ° of angles, not being or not to make arc section (5) and extended segment (4) energy at an angle of 90
There is a upper uplifting angle (8).There are one surface is convex at the arc on round and smooth slope for arc section (5) and the recess portion of screw rod (6) junction
Platform (7), the interior arc radius of arc boss (7) are slightly larger than the exradius of small steel pipe (10), when screw rod (6) screw in small steel pipe
(10) when interior, arc boss (7) understands the suitable for reading of the small steel pipe of covering part (10).
Tension hook as guy line pile, following and the right can also without tension hook, directly using small steel pipe as guy line pile,
Whole guy wires are easily put on, does not have to tense energetically when wearing, then a steel pipe (9) is taken to cover on extended segment (4), with screw rod (6)
For axle center switching tension hook because there are upper uplifting angle (8), they in switching will not with steel pipe frame (1) interference, by scheming (8)
To figure (11) as it can be seen that during tension hook is by switching, guy wire is tightened up and at the same time along arc section (5) to small steel pipe (10)
Direction sliding, when tension hook is pulled to position shown in Figure 11, guy wire will slip down to small steel pipe in the guidance of arc boss (7)
(10) on, at this moment guy wire (2) oneself through being tauted, so that it may screw out tension hook, then on internal screw thread (18) screw in one it is slim
Cheese head screw is as nut cap；Every guy wire (2) are gradually tensed according to above-mentioned steps, pay attention to the guy wire of left and right directions and up and down direction
Rotation tension so that steel pipe frame (1) uniform stressed.
With the passing of time still inevitably relaxation, wooden bed frame strung with crisscross coir ropes cannot keep tight to guy wire, and the present invention, which devises, thus makes wooden bed frame strung with crisscross coir ropes bed restore tight
Taut method 1:
Upper following and left and right side the intermediate cutting of steel pipe frame (1), in end (11) machining internal thread of cutting, pay attention to
One end processes dextrorotation internal screw thread, and end on the other side will process levogyrate inner thread, and cut off for machining internal thread
Interlude not have bending, internal screw thread easy to process and assembly；Making 4 centres again is the adjusting spiral shell that two end of nut is screw
Silk (13), screw thread is matched with above-mentioned screw thread and one end dextrorotation one end is left-handed；With adjusting screw (13) 4 sections of cutting
Steel pipe is assembled into steel pipe frame and makes round wooden bed frame strung with crisscross coir ropes bed；
In this way, when with the passing of time guy wire relaxes, when wooden bed frame strung with crisscross coir ropes is not able to maintain tight, as long as rotating adjusting screw (13) with spanner,
The tight degree of wooden bed frame strung with crisscross coir ropes can arbitrarily be adjusted.
The method 2 for easily guy wire being worn very tight:
Prepare the long nut (14) with hexagon socket head and the screw (16) with wire rope handling circle according to guy wire number, long nut (14)
Length is equal to steel pipe frame (1) outer diameter and subtracts one layer of thickness of steel pipe, and the reach of screw (16) is slightly longer than the length of long nut (14)
Degree;It drills on steel pipe frame (1) according to the arrangement position of guy wire, the direction in hole is parallel with steel pipe frame (1) plane, steel pipe frame (1)
The diameter in the hole (15) of periphery is slightly larger than the outer diameter of long nut (14), and the diameter in the hole (17) of steel pipe frame (1) inner circumferential is slightly larger than spiral shell
Follow closely the outer diameter of (16);
Long nut (14) and screw (16) respectively from the hole (15) of steel pipe frame (1) periphery and the hole (17) of inner circumferential is inner is inserted into
And it is inner that screw (16) is screwed into long nut (14), it should be noted that is only screwed into a bit of screw thread, it is taut as tensing to retain one section of screw thread
The surplus of rope;
Using the wire rope handling circle of screw (16) as guy line pile, whole guy wires are easily put on, does not have to tense energetically when wearing, then use
Long nut (14) are tightened in spanner rotation, tense guy wire (2) by screw (16);
Gradually tense every guy wire (2), pay attention to the guy wire rotation of left and right directions and up and down direction tension so that steel pipe frame
(1) uniform stressed finally again continues to pass through whole wire rope handling circles with a steel wire or rope (30), to prevent guy wire to wire rope handling circle
Reverse rotational force drive screw (16) reversion, round wooden bed frame strung with crisscross coir ropes bed just carries out.
Wooden bed frame strung with crisscross coir ropes is set to restore tight method 2:
If there are also abundant surpluses for the screw thread of screw (16), is just rotated one by one with spanner and tighten long nut (14), pass through spiral shell
It follows closely (16) and tenses every guy wire (2), round wooden bed frame strung with crisscross coir ropes bed can restore tight；
If the screw thread surplus of screw (16) is insufficient, what we can be inserted into screw (16) with a rod pulls wire rope handling circle
Rotation, even if the screw thread of screw (16) does not have surplus at this time, screw (16) can also be rotated together with long nut (14), be allowed
Wire rope handling circle takes up with guy wire rotation, since guy wire rotation takes up and can shorten length, that is, has tensed guy wire, certainly also energy
Round wooden bed frame strung with crisscross coir ropes bed is set to restore tight;
The above method can be used alone or in combination, and certainly, first release steel wire or rope (30) before pulling wire rope handling circle, entirely
Guy wire rotation in portion's puts on steel wire or rope (30) around next again.
The method 3 for easily guy wire being worn very tight: (17) only are drilled by guy wire position in steel pipe frame (1) inner ring;
Again by guy wire quantity production guy wire hook (20), the upper end of guy wire hook (20) has a Duan Yuqi at the tension pile at 80 ° of angles
(19), that tension pile (19) is fully inserted into hole (17) is inner, and follow-up of also turning at 80 ° of angles, makes guy wire hook (20) and steel pipe frame
(1) inner ring can wear guy wire at 80 ° of angles, guy wire hook (20);
Whole guy wires are easily put on, does not have to tense energetically when wearing, then pulls rotation guy wire hook (20) with spanner or rod
Guy wire hook (20) is allowed to take up with guy wire rotation.Length can be shortened by being taken up due to guy wire rotation, that is, tense guy wire, at this time
Guy wire hook (20) subjects guy wire rotation around next pulling force and guy wire by postrotational reversed rotating force, tension pile (20) simultaneously
Also this two power just are subject simultaneously, tension pile (19) is closely to tie touching with steel pipe frame (1) inner wall at this time, and as steel pipe inner wall
Part with the touching of tension pile (19) knot is that longitudinal straight transverse direction is bent upwards, and it is that tension pile (19) is prevented to rotate that this, which is bent upwards,
, as long as so allow guy wire hook (20) with guy wire rotation around next longitudinal direction for allowing tension pile (19) to be parked in steel pipe inner wall, it
Guy wire can be resisted while resisting tightening force of the guy wire to guy wire hook (20) to the reverse rotational force of guy wire hook (20), to make
Round wooden bed frame strung with crisscross coir ropes bed is steadily tight.This guy wire hook (20) production is simple, but pulling force is smaller, so being suitable for the lesser list of stress
People's bed and basket cot.
Easily the method 4 that guy wire is worn very tight: be guy wire hook with the main distinction of method 3, we it be referred to as strong
There are a pulling force block (23) in guy wire hook, its coupler body (22) upper end, and length and width are both greater than hole (17), with the connection of coupler body upper end
Face (25) is made into can match with steel pipe frame (1) inner wall, i.e., longitudinal straight transverse direction is bent upwards.Strong guy wire hook dress is described below
Enter the inner method in the hole (17) of steel pipe frame (1): before threading is inner to hole (17), one of steel pipe frame closes up mouth and does not close up first,
Coupler body (22) does not also complete, and only carries out two bendings (26) of its upper section, the lower section tail portion to be bent upwards originally
(24) it is only made into great circle arc for the time being;In addition a guidance folder (28) is made, it is slightly less than coupler body (22) directly with one section of internal diameter
The flexible sheet steel pipe of diameter makes, and splits a seam in its longitudinal direction, one end processes a groove (27), and one end processes one
Threading hole (12), inner in threading hole (12) is the moderate finer wire (21) of a hardness;
It is first that guidance folder (28) is inner with finer wire (21) inserting hole (12) when assembly, continue to be sent into finer wire (21) directly
It is come out from the mouth that steel pipe frame (1) does not close up to guidance folder (28), the tail portion (24) of strong guy wire hook is clipped with guidance folder (28), slowly
Slowly it pulls back out finer wire (21), strong guy wire hook strip will be portalled (17) by guidance folder (28);With pliers or hammer great circle arc
Tail portion (24) bending close up, it is inner and make complete that strong guy wire hook just puts into hole (17);Inner load onto of all well (17) is stretched tight by force
Rope hook simultaneously makes completely, then the mouth that closes up of steel pipe frame (1) is closed up welding;Guy wire is easily put on, strong guy wire hook is then rotated,
Tense guy wire.Length can be shortened by being taken up due to guy wire rotation, that is, tense guy wire, and strong guy wire hook subjects taut simultaneously at this time
Around next pulling force and guy wire by postrotational reversed rotating force, pulling force block (23) also just subjects this two simultaneously for rope rotation
Power, pulling force block (23) is the office closely tying touching with steel pipe frame (1) inner wall, and touching as steel pipe inner wall and pulling force block (23) knot at this time
Portion is that longitudinal straight transverse direction is bent upwards, and it is that pulling force block (23) is prevented to rotate that this, which is bent upwards, as long as so allowing strong guy wire hook
Pulling force block (23) is allowed to stop coincideing with steel pipe inner wall around next with guy wire rotation, it can resist guy wire to strong guy wire hook
Guy wire is resisted while tightening force to the reverse rotational force of strong guy wire hook, to keep round wooden bed frame strung with crisscross coir ropes bed steadily tight.
