Abstract

The utility model relates to a spring-adjustable mattress. An inner frame structure is arranged between a spring steel wire and the outer frame of the mattress, the steel wire is connected with the inner frame, and the inner frame is connected with the outer frame through a screw bolt. The screw bolt is rotated, the inner frame can approach or leave the outer frame, and thereby, the spring of the steel wire can be adjusted.

Description

Spring-adjustable mattress

The utility model belongs to furniture manufacturing industry, the capable product of mattress technical field.

Existing mattress construction technology that can the regulating spring degree of tightness is that application number is 93203351.1 and is called the utility application of " the adjustable mattress of spring degree of tightness ", each spring of this technology is connected with bolt, make spring collapse purpose tight or that loosen for reaching, need to adjust the bolt that each and spring join.And the net that existing sping mattress polyembryony hand braided steel wire becomes, horizontal and vertical steel wire all has many heads, also just need bolt of each connection, bolt of every in other words adjustment just can make a steel wire collapse tight or loosen, this can result in hand cramps to the user, and the degree varies that screws of each bolt causes, and also can cause degree of tightness to differ, and also influences the service life of mattress.

There is above-mentioned weak point in the utility model and provides the several bolts of a kind of public adjustment just can make whole steel wire be tight or loose new structure technology simultaneously in order to overcome the existing mattress that can adjust the spring degree of tightness just.

The utility model is realized by following technology:

Also being provided with an inner frame between outside framework and spring or steel wire, fixedlys connected with inner frame in spring or steel wire termination.Inner frame connects with outside framework by bolt again, and screw thread has been attacked in the inner frame hole that cooperates with bolt, and when left-handed or dextrorotation bolt, variation has taken place the distance of inner frame and outside framework, thereby makes the spring of fixedlying connected with inner frame collapse tight or loosen.

Further set forth the utility model content below in conjunction with Figure of description and embodiment.

Fig. 1 is the utility model schematic diagram;

The cross sectional view that Fig. 2 connects for the utility model internal and external frame.

Shown by reference numeral is: 1-outside framework, 2-inner frame, 3-spring, locking nut in the 4-bolt, 5-, 6-outer locking nut.

Outside framework (1) is selected angle bar for use in an embodiment with inner frame (2), the steel wire that spring (3) normally forms with braided steel wire, the skeleton structure of whole mattress is looked the mode that the utility model is chosen, inner frame (2) can be arranged on 1～4 direction on outside framework (1) plane, promptly, both can unidirectionally adjust, also can symmetry adjust or the three-dimensional adjustment, perhaps four direction adjustment, decide according to user's needs, but no matter adopt the adjustment of several directions, the cross section of its draw bail is as shown in Figure 2, spring (3) is fixedly connected with inner frame (2), punching, and welding all can, and inner frame (2) is to connect by bolt (3) with outside framework (1), attack the screw thread that matches with bolt (3) on the angle bar of inner frame, screw in then in the bolt hole of inner frame in the boring of bolt (3) elder generation's insertion outside framework (1), also be provided with interior locking nut (5) and outer locking nut (6) in the inboard of inner frame and outside framework and play anti-stripped thread effect.

The steel wire of being made up of spring (3) is the main functional parts that padding for spring bed supports the user, if the user wish the simmons spring tight a bit or pine a bit, need only with screwdriver rotating bolt (3) make inner frame (2) near or leave outside framework (1) and just can meet the demands, though simmons has face shield to cover each mattress side, but need only be in the face shield side correspondingly stamp several holes, with becket fixing hole edge, the head of bolt (3) has just exposed by the hole.

The utility model has overcome the defective that bolt of every accent can only a spring wire of degree of tightness, compared with the prior art by adjusting several limited bolts, make whole inner frame parallel, it is tight or loosen to drive whole spring steel wire mesh, has improved efficient, has guaranteed that also the spring degree is consistent.

Claims

1, a kind of mattress of adjusting the spring degree of tightness, the spring that makes mattress that screws or unscrew by bolt is the state tight or that loosen that collapses, it is characterized in that: between housing (1) and spring (3), also be provided with an inner frame (2), fixedly connected with inner frame in the termination of spring, inner frame connects with outside framework (1) by bolt (4).

2, mattress according to claim 1 is characterized in that attacking on the inner frame (2) screw thread that matches with bolt (3).
