Abstract

The utility model relates to a middle part positioning structure of a folding bed frame. The folding bed frame comprises bed frame support legs, a left vertical rod and a right vertical rod, wherein the bed frame support legs are formed by multiple groups of cross rod groups; the left vertical rod and the right vertical rod are pivoted at the tops of the bed frame support legs and are used for being matched with the bed surface; each vertical rod is formed by the pivoting of at least two rod members through a pivoting piece; the pivoting piece of each rod member of at least one vertical rod is provided with a locking device; the locking device comprises a button, a locking block and a locking seat; the locking block elastically extends into the pivoting piece and the rod member; the locking seat is matched with the button on the locking block; and the button is movably matched in the locking seat and is in contact with the locking block. By arranging the locking devices at the pivoting pieces of the left and right vertical rods matched with the bed surface in the bed frame, the rod members forming the vertical rods can not rotate or waggle relative to the pivoting pieces in the bed frame unfolding process, thereby achieving the support stability after the bed frame is unfolded, and simultaneously ensuring the unfolding integrity of the bed frame so as to facilitate moving or carrying.

Description

Folding bedstead middle part location structure

Technical field

The utility model relates to a kind of folding bedstead, refers to a kind of folding bedstead middle part location structure especially.

Background technology

Having now and folding bedstead is to cooperate the bed surface that can fold to constitute by the leg that can fold, and mostly the leg that can fold is to adopt plural groups crossbar fabric to become, or short strut direct and that bed surface formation articulates constitutes; And mostly the bed surface that can fold is to be formed by at least two unidirectional pivot joints of unit bed surface, and then realize to launch and folding function, and bed surface is to rely on to be positioned at a longitudinal holding pole of body both sides and to cooperate unidirectional articulated part to realize cooperating.Usually this unidirectional articulated part only is to play the effect that articulates longitudinal holding pole, and bedstead the problem that supports shakiness can occur rocking and exist in actual use.Even when the bedstead that launches moved, also can cause a problem of body central region sinking, make troubles to use.

The utility model content

The purpose of this utility model is to provide a kind of assurance bedstead ease of use, improves the folding bedstead middle part location structure that bedstead supports steadiness.

For achieving the above object, solution of the present utility model is:

A kind of folding bedstead middle part location structure, wherein should comprise the bedstead leg that plural groups crossbar group forms by folding bedstead, and bedstead leg top being used for of articulating cooperate bed surface about two vertical poles, each vertical pole is to be articulated by pin-jointing piece by at least two pole spares to constitute; Wherein: the pin-jointing piece place at least one each pole spare of vertical pole is provided with a locking device, this locking device comprises button, lock dog and a lock, flexible the stretching of this lock dog places pin-jointing piece and rod member, lock is matched with on button and the lock dog, and wherein being matched with in the lock and with lock dog of button activity contacts.

Described lock dog is to be set to two, and it cooperates back-moving spring respectively and places two rod members.

The outer end of described lock dog is to form arcwall face.

Arrange on the described pin-jointing piece for lock dog and stretch the lockhole of putting.

Described button rear portion forms push plate, and its length is greater than the length between two lock dogs, and the button front end forms the press section.

Described lock cover places outside the pin-jointing piece, and its middle part is provided with mating holes and protrudes out for the splenium that connects of button, and the push plate of button is to place lock to contact with two lock dogs.

After adopting said structure, folding bed of the present utility model middle part location structure, pin-jointing piece place by two vertical poles about cooperation bed surface in bedstead arranges locking device, when making bedstead launch, the rod member that constitutes vertical pole can not rotate or rock relative to pin-jointing piece, and then the steadiness of realization bedstead expansion back support, guarantee the globality that bedstead launches simultaneously so that move or move.

The specific embodiment

Extremely shown in Figure 5 as Fig. 1, the utility model has disclosed a kind of folding bedstead middle part location structure, wherein should comprise the bedstead leg that plural groups crossbar group 1 forms by folding bedstead, and bedstead leg top being used for of articulating cooperate bed surface about two vertical poles 2, each vertical pole 2 is to be articulated by pin-jointing piece 3 by at least two pole spares 21 to constitute;

Key of the present utility model is: pin-jointing piece 3 places at least one vertical pole 2 each pole spare 21 are provided with a locking device 4, this locking device 4 comprises button 41, lock dog 42 and a lock 43, these lock dog 42 flexible stretching place pin-jointing piece 3 and rod member 21, lock 43 is matched with on button 41 and the lock dog 42, and wherein being matched with in the lock 43 and with lock dog 42 of button 41 activities contacts.

Cooperate shown in Fig. 2,4, lock dog 42 in the present embodiment is to be set to two, it cooperates the back-moving spring (not shown) respectively and places two rod members 21, lock dog 42 is that flexible stretching places outside the rod member 21, the outer end of this lock dog 42 is to form arcwall face, in order to be extruded retraction smoothly from the side of pin-jointing piece 3; Corresponding two lock dogs 42 arrange lockhole 31 at pin-jointing piece 3; Described button 41 rear portions form push plate 411, and its length is greater than the length between two lock dogs 42, and button 41 front ends form press section 412; Lock 43 is that cover places outside the pin-jointing piece 3, and its middle part is provided with mating holes 431 and protrudes out for the splenium 412 that connects of button 41, and the push plate 411 of button 41 is to place lock 43 to contact with two lock dogs 42.

Shown in Fig. 2,3, when folding bed launch to use, each pole spare 21 of vertical pole 2 was in the same horizontal plane, and the lock dog 42 on each rod member 21 is just stretched the lockhole 31 that places pin-jointing piece 3, each rod member 21 of this moment is to be in locked state, and namely rod member 21 can't rotate relative to pin-jointing piece 3; Meanwhile connect button 41 also by lock dog 42 pushing tows.Because each rod member 21 at bedstead middle part all has two or more points of engagement with pin-jointing piece 3, so can realize more firm cooperation between the two, can guarantee that so bedstead launches the stability that back rod member 21 cooperates, and improves the support steadiness of bedstead.

Shown in Fig. 4,5, when folding bed is carried out folding, press button 41 and can promote lock dog 42 retraction in the rod member 21, each rod member 21 of the application of force folds relatively simultaneously again, the cooperation that can make lock dog 42 break away from the lockhole 31 of pin-jointing piece 3 is to realize the function that folds of bedstead.

For further improving the steadiness of bedstead, can about bedstead, locking device 4 all be set pin-jointing piece 3 places of two vertical poles 2, realize bedstead middle part preferred positioning function.In addition, for ease of implementation and operation, this locking device 4 is provided in a side of the outer fix of bedstead.

In sum, folding bed of the present utility model middle part location structure, pin-jointing piece 3 places by two vertical poles 2 about cooperation bed surface in bedstead arrange locking device, when making bedstead launch, the rod member 21 that constitutes vertical pole 2 can not rotate or rock relative to pin-jointing piece 3, and then the steadiness of realization bedstead expansion back support, guarantee the globality that bedstead launches simultaneously so that move or move.
