The specific embodiment
Below be specific embodiments of the invention and in conjunction with the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As depicted in figs. 1 and 2, tent comprises umbrella cover 2, stake bar 1, center-pole 5, tent frame 3.
Specifically, a stake bar 1 has four and arrange and to be square; Center-pole 5 is positioned at foursquare center, and tent frame 3 connects per two adjacent stake bars 1 and is connected a bar 1 and center-pole 5, and umbrella cover 2 is fixed on the tent frame 3.On center-pole 5, be provided with two adapter sleeves 4, i.e. adapter sleeve 1 and adapter sleeve 4 two, tent frame 3 is hinged on the adapter sleeve 4, and wherein adapter sleeve 1 is fixed on the lower end of center-pole 5, and adapter sleeve 4 two can move axially along center-pole 5.
Embodiment one
As shown in Figures 2 and 3, this umbrella cover of tent 2 slack adjusters comprise center-pole 5, push rod 6, elevating mechanism, self-locking mechanism.
Specifically, center-pole 5 in a tubular form, push rod 6 is positioned at center-pole 5 and can moves axially along push rod 6 inwalls, the upper end of push rod 6 passes the top of center-pole 5 and leans with umbrella cover 2.
Elevating mechanism is positioned at center-pole 5 and drives this mechanism and can make push rod 6 liftings, it comprises the power rail 8 that is positioned at center-pole 5, one end of power rail 8 passes the bottom of center-pole 5 and passes adapter sleeve 1 and be connected with handle 7, being provided with on power rail 8 can axially movable driving member, and an end of driving member links to each other with the following of push rod 6.
The circumferentially fixing and handle 7 of handle 7 and power rail 8 is fixed on the lower surface of power rail 8 by screw 11.Handle 7 comprises the handle body 71 and the handgrip 72 of handing-over at handle body 71 that is connected mutually with power rail 8, and handle body 71 is resisted against on the adapter sleeve 1, and this handle 7 can make things convenient for rotational power bar 8.
As shown in Figure 3 and Figure 4, power rail 8 adopt plastic materials make and its lateral surface on have a helical arc groove 82.Above-mentioned driving member is a helical spring 9, helical spring 9 axially is set on the power rail 8 and spring body embeds in the groove 82, the spiral coefficient of helical spring 9 is identical with the spiral coefficient of power rail 8 further groove 82, thereby helical spring 9 can be complementary with groove 82 closely.Be fixed with locking plate 10 in upper end at helical spring 9, the circumferentially fixing and end face of locking plate 10 and the lower surface of push rod 6 lean with center-pole 5 for locking plate 10, this locking plate 10 adopts plastics or metal material is made and its end face is the plane, so this locking plate 10 has the effect that can prevent that promptly helical spring 9 from circumferentially rotating, and has made things convenient for spring to be connected with push rod 6 again.Power rail 8 is circumferentially rotated and helical spring 9 is moved axially when shaking handle 7, helical spring 9 drives vertical rods and does and rise or descending motion, thereby has made things convenient for the elasticity of regulating umbrella cover 2.
Helical spring 9 adopts metal material to make and itself has elasticity, and metal and plastics are in contact with one another, and frictional force is big between the two for it, makes between helical spring 9 and the power rail 8 and can produce self-locking; Helical spring 9 can make push rod 6 produce certain buffering when umbrella cover 2 is subjected to external force suddenly, thereby can reduce the stressed of tent frame 3 parts such as grade, effectively raises the safety of tent.
Though helical spring 9 and power rail 8 can produce self-locking, in order further to improve the safety of this device, on the center-pole 5 of this device, also be provided with the self-locking mechanism that can prevent that push rod 6 from descending automatically.Self-locking mechanism comprises the adapter sleeve 1 that is fixed on the center-pole 5, the free end of above-mentioned handle 7 handgrips 72 can embed adapter sleeve 1 and be fixed on the adapter sleeve 1, at this moment, because the free end of hand handgrip 72 is fixed, so making handle 7 integral body can't rotate, thereby reach the purpose that prevents that power rail 8 from rotating, realize the self-locking of this device.
As shown in Figure 5, as the another kind of scheme of such scheme, driving member is that drive link 12 and drive link 12 circumferentially are fixed in the center-pole 5.The lower end of drive link 12 is set on the power rail 8 and drive link 12 and power rail 8 are movably connected by screw thread connects, and the lower end of the upper end of drive link 12 and push rod 6 leans.Between drive link 12 and push rod 6, be provided with spring 13, the two ends of spring 13 are resisted against respectively on the end face of drive link 12 and push rod 6, spring 13 can make push rod 6 produce certain buffering when umbrella cover 2 is subjected to external force suddenly, thereby reduce the stressed of tent frame 3 parts such as grade, effectively raise the safety of tent.
Embodiment two
As shown in Figure 6, present embodiment is basic identical with structure and the principle of embodiment one, different place is: elevating mechanism comprises the power rail 8 that is positioned at center-pole 5, one end of power rail 8 passes the bottom of center-pole 5 and is connected with handle 7, push rod 6 circumferentially is fixed in the center-pole 5, and the lower end of push rod 6 is set on the power rail 8 and push rod 6 and power rail 8 are connected by screw thread.Shake handle 7, power rail 8 circumferentially rotates, and push rod 6 moves axially, and has promptly regulated push rod 6 upper ends to the distance between center-pole 5 lower ends, thus the elasticity that realizes regulating umbrella cover 2.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used stake bar 1 morely; Umbrella cover 2; Tent frame 3; Adapter sleeve 4; Adapter sleeve 1; Center-pole 5; Push rod 6; Handle 7; Handle body 71; Handgrip 72; Power rail 8; Annular convex ring 81; Groove 82; Helical spring 9; Locking plate 10; Screw 11; Drive link 12; Spring 13 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
