Description

A kind of Portable hammock that expansion locks certainly

Technical field

The utility model relates to travel or camp appliances, it is related to hammock and hammock expanding unit, espespecially a kind of expansion is self-locking Dead Portable hammock.

Background technique

Traditional hammock is divided into simple soft hammock from form, and rigid support formula hammock type and multi link formula foldable structure are hung Bed.

Simple soft hammock is only applicable to open air, often hangs hammock both ends long rope on trees, in urban environment, out In the requirement to protect trees, mostly forbid hanging hammock in the environment such as park on trees.Rigid support hammock is using rigidity knot Structure body simulates a fixed spacing trees, and hammock hangs on two rigid links, or have basket-hanging suspension bed structure structure by chain, Chain etc. is connected in rigid hanger structure, and such structural volume quality is larger, mobile inconvenient, is usually used in fixed place and is used. Multi link formula foldable structure hammock constitutes hammock hanger body by the expansion of connecting rod, then by additional locking-type structure, such as with Under link in be exactly such structure：

Or geometry self-locking structure, the structure as being exactly in link below：

（https://detail.tmall.com/item.htm id=18866625177&_u=t2dmg8j26111）

Reach the stabilization of hanger body.

Geometry self-locking is by moving to dead-centre position during mechanism part expansion, or reaches hinge travel limit and come pair Structure after expansion is locked（If the toggle joint type Gunlock structure in glug pistol is locked by dead point, closed cartridge chamber）, this Structure to the stress of single direction have it is preferable resist effect, but other directions can destroy the steady of structure small power It is qualitative.

By spring holder, the dedicated locking device that marble screw etc. is docked with fixed notch comes to knot component self-locking Structure is locked, and be common are child's scooter handrail at vehicle body and is opened hinge design fastly, spring is fixed when passing through mechanism deploying Position pin slides into buckle under pressure to locked handrail.Due to increasing dedicated locking device, the complexity of mechanism and Unlocking complexity all effected.

Additional locking-type is deployed into behind predetermined position by structure is added connecting rod or plug-in type positioning pin to lock to structure Extremely, in general, it is preferable to lock effect, but dismounts more inconvenience.

Summary of the invention

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of Portable suspensions that expansion locks certainly Bed.Make the functional parts of foldable structure while expansion, undertake the function of locking mechanism component, additional lock is carried out to mechanism Extremely, it is intended to which the portability for making hammock fold frame structure is enhanced, and the longer time can be provided when having and rocking demand Shake, the practicability of Portable hammock gets a promotion.

Technical solution adopted by the utility model to solve its technical problems is：It is portable from what is locked to provide a kind of expansion Hammock, it is characterised in that：Including self-locking folding Portable support device and hammock body, the self-locking folding Portable support device Connect including two lateral bottom bars, two longitudinal bottom bars, four vertical waist bars, a mandril, four center link blocks, two mandrils Spindle and two articulated shafts are picked up, two lateral bottom bars and two longitudinal bottom bars are two sections of bar structures, and two sections of bodies of rod pass through Articulated shaft three or articulated shaft five are hinged, and two lateral bottom bar both ends are affixed with two center link blocks respectively, two longitudinal bottom bars Both ends are hinged with four vertical waist bar bottom ends respectively, form revolute pair with four center link blocks by four vertical waist bars and connect Relationship, forms rectangular seats by four center link blocks and two lateral bottom bars when expansion, and four vertical waist bar bottom ends are divided It is not hinged with four center link blocks of rectangular seat, with two vertical waist bars for one group, two groups of vertical waist bar top difference Hinged by mandril connecting shaft, two vertical waist bars and a longitudinal bottom bar collectively constitute triangle support frame, mandril when expansion Both ends pass through two Quick Release pocket sets respectively and connect axis connection with two mandrils；The hammock body includes erecting by overhang and hammock, The erecting by overhang includes supporting mass, hanging body, and supporting mass is fixed in mandril connecting shaft, and hanging body is rotationally placed on bearing In vitro, hammock is hung on hanging body.

The Quick Release pocket set includes the first connecting portion with slot and the second connecting portion with convex bamboo shoot, and convex bamboo shoot are injected In slot, first connecting portion connect axis connection with mandril, and second connecting portion is connect with mandril.

The supporting mass both ends are positioned with axle sleeve and are fastened.

The utility model has the beneficial effects that：Effect fruit more than one for sufficiently having used mechanism part, using 3 conduct of connecting rod Space folding structure locks component, and having reached outer plus locking-type structure in the case where not increasing dedicated locked component can bear Multidirectional stressed advantage, while number of parts is reduced, while connecting rod 3 reaches locking position while mechanism deploying acts, Simplify locked operation.And designing has the fast hanging point of bearing-type hammock, increases the practicability of Portable hammock.
