CN2804286Y - Hack lever of tent with arch top - Google Patents

Abstract

The utility model discloses a hack lever of a tent with an arch-shaped top, which is mainly composed of upright posts, a side rod group and a top rod group, wherein one end of the top rod group is pivoted on the tops of the upright posts, the other end is pivoted together, the side rod group is pivoted between two adjacent upright posts and is composed of at least four S-shaped bend rods which are crossed and pivoted, each upper bend rod and each lower bend rod which are corresponding are arranged symmetrically, the middle of the upper bend rod and the lower bend rod is pivoted together, and the heads and the tails of a left bend rod and a right bend rod which are adjacent are pivoted together. The structure can make the top of the tent smooth further, makes support more firm and avoids the generation of the phenomena of the damage and the collapse of the top of the tent caused by centralized stress.

Description

The hack lever of the tent of arc top

Technical field

The utility model relates to the technical field of tent, and is especially relevant with the hack lever structure of the tent of arc top.

Background technology

In the prior art, the structure of tent is varied, roughly be made up of column 1 ', side lever group 2 ' and push rod group 3 ', top, the other end that an end of push rod group 3 ' is articulated in column 1 ' then are articulated, and side lever group 2 ' is articulated between the two adjacent root posts 1 '.Wherein, a kind of tent is arranged as shown in Figure 1, because of its side lever group 2 ' is formed by straight-bar 21 ' the eccentric pivot joint, so side lever group 2 ' is low, the middle high shape in both sides, the side of top then slightly is the arc that upwards arches upward.The side lever group 2 ' of this structure has not only promoted the top space of tent, gives the comfortable sensation of people, and, the arc top, outward appearance is new and original, further promotes product quality, is subjected to user's favor.

But, this eccentric side lever group 2 ' that articulates obviously is overshooting shape on the top that straight-bar 21 ' intersects pivot joint, cause the top of tent bracket to be uneven, when enclosing cloth and cover on the tent, be subjected to the straight-bar 21 ' apical support of projection promptly to form the top of uneven (not slick and sly), the top side just rises and falls, the weight of whole top is concentrated on these several protruding points, unbalance stress appears easily, the top disrepair phenomenon, and, if desire improves the camber of top, the then essential eccentric degree that articulates that strengthens, this not only increases the rough degree of top, and it is insecure that pivot joint is supported, even cause the top phenomenon of collapsing.

The utility model content

The purpose of this utility model is the hack lever that is to provide a kind of tent of arc top, so that top is more slick and sly, supports more firmly, avoids stressed and concentrates the top disrepair phenomenon that causes and the top phenomenon of collapsing takes place.

In order to achieve the above object, solution of the present utility model is:

The hack lever of the tent of arc top, mainly form by column, side lever group and push rod group, top, the other end that one end of push rod group is articulated in column then are articulated, the side lever group is articulated between the two adjacent root posts, the side lever group is articulated by four " S " type knees intersections at least and forms, wherein, every two corresponding up and down knees are the symmetry shape setting and the centre is articulated, and two adjacent knees of the left and right sides are articulated from beginning to end.

Above-mentioned push rod group is articulated by two " S " type knees intersections at least and forms middle being articulated of every two corresponding up and down knees.

Above-mentioned push rod group is articulated by " S " type knee intersection more than eight and forms, is articulated in the middle of every two corresponding up and down knees, and the four piece knee ends of four knee ends above the top center is positioned at below being articulated, being positioned at are articulated.

After adopting said structure, the utility model articulates by knee, can make the side of top be the arc that upwards arches upward equally, has promoted the top space of tent, gives the comfortable sensation of people, and the arc top, and outward appearance is new and original.Simultaneously, the utility model is owing to changed the shape that constitutes the unit rod member of side lever group, change straight-bar of the prior art into " S " type knee, so, be slick and sly butt joint on the top that knee articulates, but not overshooting shape of the prior art when enclosing cloth and cover on the tent, promptly forms the more slick and sly arc top of side, the weight fraction of whole top is dispersed on the side lever group of arc, avoided stressed concentration phenomenon, and, if desire improves the camber of top, then only need to increase knee, top still keeps slick and sly arc, and pivot joint is supported more firm, determines and does not have the top phenomenon of collapsing.

Description of drawings

Fig. 1 is the structural representation of tent side lever group in the prior art;

Fig. 2 is the structural representation in the utility model side lever group utilization tent.

The specific embodiment

As shown in Figure 2, the utility model has disclosed the hack lever of the tent of arc top, mainly is made up of column 1, side lever group 2 and push rod group 3.Top, the other end that one end of push rod group 3 is articulated in column 1 then are articulated, and side lever group 2 is articulated between the two adjacent root posts 1.

Key of the present utility model is that side lever group 2 is formed by the 21 intersection pivot joints of four " S " type knees at least.It is fixed that the radical of knee 21 is come by the size of tent, but all be the even numbers root.The side lever group 2 of tent shown in present embodiment Fig. 2 is to be intersected to articulate by the six roots of sensation " S " type knee 21 to form, and wherein, every two corresponding up and down knees 21 are the symmetry shape setting and the centre is articulated, and adjacent two knees, 21 head and the tail in the left and right sides are articulated.As for four or knee 21 more than the six roots of sensation, its pivot joint mode is similar to present embodiment, does not do at this and gives unnecessary details.

This structural change constitute the shape of the unit rod member of side lever group 2, change straight-bar 21 ' of the prior art into " S " type knee 21, so, be slick and sly butt joint on the top that knee 21 articulates, but not overshooting shape of the prior art, when enclosing cloth and cover on the tent, promptly form the more slick and sly arc top of side, the weight fraction of whole top is dispersed on the side lever group 2 of arc, has avoided stressed concentration phenomenon, and, if desire improves the camber of top, then only needing increases knee 21, and top still keeps slick and sly arc, it is more firm to articulate support, determines and does not have the top phenomenon of collapsing.

The unit member structure of the utility model side lever group 3 also can apply in the push rod group 3, and its structure is similar to side lever group 3, and this paper does not give diagram.Such push rod group 3 is articulated by two " S " type knees intersections at least and forms, form as intersecting to articulate by " S " type knee more than eight, it is fixed that the radical of knee is also come by the size of tent, be articulated in the middle of every two corresponding up and down knees, and four knee ends above the top center is positioned at are articulated, four knee ends that are positioned at the below are articulated, by changing the shape of the unit rod member that constitutes push rod group 3, change straight-bar of the prior art into knee, make and articulate that the limit is arc shaped on the push rod group 3 form, when enclosing cloth and cover on the tent, supported by arc shaped push rod group 3 and side lever group 2, whole top all forms arc, has more aesthetic utility.

This case is applicable to various tents, can be used for substituting side lever group 2 and push rod group 3 in the existing tent, thereby forms the arc top, is not subjected to the restriction of present embodiment diagram as for the concrete structure of tent.
