The utility model drives the racks to move as so to drive the gear pin-jointed with the fulcrum bars to rotate through meshed gear racks and the elastic apparatus, thus realizing functions of automatically extending and retracting the fulcrum bars, therefore, the utility model has fewer rod pieces and simpler structure compared with the conventional articles; in addition, the elastic apparatus can be arranged in the fixed seat so as to have the protecting and water-proof functions, and the service life of the utility model is longer.

Description

The tent top folding device

Technical field

The utility model relates to the parts of tourism or camp appliances, is meant a kind of tent top folding device especially.

Background technology

In the prior art, the top folding device structure that a kind of break camp arranged as shown in Figure 1, 2, be to connect a collapsible pole 1 ' of cover and secondary pole 5 ' and constitute tent bracket, mainly be made up of holder 2 ', spring 3 ', spread frame 4 ' and baffle plate 6 ', support bar 2 ' top is provided with the connection nest 21 ' that articulates each pole 1 '; Spring 3 ', spread frame 4 ' are placed on the support bone 22 ' that extends holder 2 ' bottom successively, baffle plate 6 ' is that the exhibition of being fixed on is protected a support bone 22 ' of frame 4 ' bottom upward so that spread frame 4 ' is had a position-limiting action, and an end of each secondary pole 5 ' is to be articulated on each pole 1 ', and the other end is articulated in the pivot joint nest 41 ' of spread frame 4 '.When folding after the combination, spring 3 ' is to be in the compress energy storage state, secondary pole 5 ' and pole 1 ' be closing together, and spread frame 4 ' is to be positioned at support bone a 22 ' nearly upper position; When launching tent, only need the application of force of pine oil to pole 1 ', spread frame 4 ' props up support bone 22 ' in the effect lower edge of spring 3 ' reset force and is displaced downwardly to baffle plate 6 ' position, meanwhile secondary pole 5 ' can be shored out each pole 1 ' under the drive of spread frame 4 ', therefore realizes the expansion function of whole tent.

But but there is following defective in the tent folding device of this structure:

1, need the secondary pole pair pole of a cover to support, thereby required rod member is more;

2, spring exposes, and is subjected to the rainwater etch in long-term the use and influences its application life.

The utility model content

The purpose of this utility model is to provide the tent top folding device of less relatively, the simple in structure and long service life of a kind of rod member.

For achieving the above object, solution of the present utility model is: a kind of tent top folding device, mainly having the holder connection one cover pole that articulates nest by one constitutes, wherein: each pole is that the nest that respectively articulates by pin joint seat and holder is articulated, and the inboard of this pin joint seat forms gear, and a sliding sleeve with tooth bar is to be fixed on the elastic device, and this elastic device is to be fixed on the holder, the sliding sleeve upper rack just and the gears engaged of each pin joint seat together.

Described holder is a sleeve, its outer wall periphery is provided with the pivot joint nest, each articulates and forms fluting on the sleeve wall in the nest so that the gear of pin joint seat is stretched puts wherein, and being nested with elastic device, sliding sleeve places this sleeve, the upper end of elastic device is fixed on the top of sleeve, and its underpart is to stretch to place this sliding sleeve, and the lower end is fixed in the sliding sleeve.

The inboard formative gear of described pin joint seat, and the outside forms fixed cover, an end of pole is to be fixed in this fixed cover.

Described elastic device is spring or telescopic cylinder.

After adopting such scheme, because tent top folding device of the present utility model is by the rack-and-pinion that is meshing with each other, drive moving of tooth bar by elastic device again and drive the gear rotation that articulates pole, realize the function that pole is launched and folded automatically with this, therefore commonly using product relatively the utlity model has following advantage:

1, rod member is few, simple in structure, only needs a cover pole can realize the expansion supporting role of tent, and the product of commonly using have relatively saved the secondary pole of supporting each pole;

2, elastic device can be built in the holder, to its function with a protection waterproof, makes its longer service life with this.

The specific embodiment

As Fig. 3 and cooperate shown in Figure 10ly, tent top folding device of the present utility model comprises one group of pole 1, a holder 2, an elastic device 3, a sliding sleeve 4 and one group of pin joint seat 5;

Holder 2 is a sleeve, and its outer wall periphery is provided with and articulates nest 21, and each articulates on the sleeve wall in the nest 21 and forms fluting 22;

Elastic device 3 is that the flexible gas that an inside and

outside loop bar

31,32 forms lacks (or being a spring);

The number of corresponding pole 1 vertically is provided with one group of tooth bar 41 on sliding sleeve 4 outer walls;

The inboard formative gear 51 of pin joint seat 5, and the outside forms fixed cover 52, an end of pole 1 is to be fixed in this fixed cover 52 by locking part 11.

Cooperate again shown in 4,5, elastic device 3 is placed in the sliding sleeve 4 during combination, lower end of loop bar 31 is fixed on the bottom of sliding sleeve 4 in it, sliding sleeve 4 and elastic device 3 place the sleeve of holder 2 in the lump, and the upper end of the outer loop bar 32 of elastic device 3 is fixed on the top of holder 2, the gear 51 that connects the pin joint seat 5 of pole 1 is to stretch through the fluting 22 of holder 2 to place sleeve and tooth bar 41 lucky and on the sliding sleeve 4 to be meshed, and the middle part of pin joint seat 5 is articulated in it on pivot joint nest 21 of holder 2 by pivot 6, finishes the combination of whole device with this.

Extremely shown in Figure 10 as Fig. 8, when tent is in folding, external force imposes on the pole 1, make each pole 1 be in concentrated collapse state, this moment, elastic device 3 was in the compress energy storage state, loop bar 31 is to close in the outer loop bar 32 promptly, and meanwhile, the drive of loop bar 31 reaches down the top that is positioned at holder 2 under the promotion of gear 51 in sliding over.

Cooperate Fig. 4 to shown in Figure 7 again, pine oil is to the application of force of pole, under the elastic force effect of elastic device 3, the outer relatively loop bar 32 of interior loop bar 31 stretches out, meanwhile drive sliding sleeve 4 relative fixed seats 2 and move down, then promptly can to drive the gear 51 by pin joint seat 5 be that the axle center rotates with it with the pivoting point that articulates nest 21 to the tooth bar 41 on the sliding sleeve 4, and then the fixed cover of pin joint seat 5 just moves up and tent pole 1 can be launched, and whole tent is launched, finish the function of opening tent automatically.

Otherwise, forcing in each pole 1 and make it concentrate when folding, the gear 51 of pin joint seat 5 can drive sliding sleeve 4 relative fixed seats 2 and move up, and elasticity of compression device 3 makes it be in the compress energy storage state to demand the expansion of tent urgently simultaneously.

To sum up, the utility model is by pitch wheel 51 tooth bars 41, drive mobile gear 51 rotations that drive pivot joint pole 1 of tooth bar 41 again by elastic device 3, realize the function that pole 1 is launched and folded automatically with this, so it is few, simple in structure to commonly use the product rod member relatively; Elastic device 3 can be built in the holder 2 in addition, to its function with a protection waterproof, makes its longer service life with this.
