Abstract

The utility model relates to a spring mattress with spring tension-adjustable function. One end of a draw hook is bent backwards into a hook shape hooks side cabinet steel wire which is connected with reticular spring, and the other end is provided with a section of screw thread which is matched with screw nuts which are embedded on the holes of the bed frame. The spring mesh can be tightly pulled through rotating the draw hook. The utility model not only can adjust the tension of the spring mattress according to people's requirement but also can avoid that the bed body collapses after the spring mattress is used for a period of time. The service life of the mattress is prolonged, and the external shape is kept unchanged.

Description

The adjustable mattress of spring degree of tightness

The adjustable mattress of spring degree of tightness relates to the net like sping mattress, belongs to furniture manufacturing industry mattress technical field.

Existing net like sping mattress, whole spring net are all consolidated extremely on bed frame, cannot adjust its spring degree of tightness.Even it is good again that its weak point is spring-mass, metal federation fatigue, time one length also can be out of shape, and presentation quality will be subsided, both influenced to spring mattress bed one distortion, also causes the inconvenience in the use.

The utility model has netted sping mattress above shortcomings part now in order to overcome just, and a kind of mattress of adjustable springs degree of tightness is provided.

The utility model is achieved by the following technical solution:

One end back bending of drag hook is become hook-shaped, hook the frame steel wire, make the netted spring that is connected with the frame steel wire be pine or be tight because of drag hook power size, the other end tapping of drag hook has one section screw thread, this thread segment cooperates with nut on being embedded in the bed frame hole, by the turn-knob drag hook, make the moving whole shape tensioned of throwing the net of border steel silk ribbon, satisfy people and require the degree of tightness state that reaches.

Further specify content of the present utility model below in conjunction with Figure of description and embodiment.

See Figure of description, wherein:

Fig. 1 is the partial sectional view of the utility model structure

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

The label of annotating is on the accompanying drawing: 1-spring, 2-frame steel wire, 3-drag hook, 4-bed frame, 5-nut.

The utility model embodiment adopts angle steel as bed frame (4), is drilled with some holes in that angle steel one side is uniform in advance, is used for inserted num (5).Netted sping mattress is by after spring wire is rolled into the spring shape one by one, two being wrapped in frame steel wire (2) respectively tightens again, the frame steel wire generally bends to rectangle, horizontal spring wire two is fixed on the rectangle broadside, and perpendicular spring wire two is fixed on rectangular narrow limit, forms a spring net (1) according to the demand of density.Netted spring places in the bed frame (4), collapses tightly by drag hook (3).Drag hook (3) one end back bending become hook-shaped, hook frame steel wire (2), other end tapping has one section screw thread, and this thread segment cooperates with nut (5) on being embedded in bed frame (4), by the rotation drag hook can make the border steel silk near bed frame, reach the purpose that collapses tight spring (1).Because drag hook all hooks four limits of frame steel wire, four limits simultaneously tightly or only tight two limits of width can make spring net collapse tightly.The internal thread hole of nut (5) is a through hole, and drag hook (2) rotates by self can stretch out nut bore.Usually, if found the spring net pine or too tightly collapse, can adopt instrument such as wrench to adjust drag hook, drag hook also can be made the shape that cross section is a rectangle, instrument turn-knob easy to use near thread segment.

The utility model is compared with existing sping mattress, and it is arbitrarily adjustable to have degree of tightness Advantage, the lathe bed that the what spring fatigue is caused subsides or spring collapses too tightly not enough easyproly Suitable, can do corresponding adjustment, can prolong the service life of sping mattress, Keep the face shaping of mattress, satisfy the different degree of tightness requirement of user.

Claims

1. the adjustable mattress of spring degree of tightness, form by spring (1), frame steel wire (2), drag hook (3), bed frame (4), it is characterized in that: an end back bending of drag hook (3) becomes hook-shaped, hook frame steel wire (2), other end tapping has one section screw thread, cooperates with nut (5) on being embedded in bed frame (4) hole.
