Description

A pintle subassembly that is arranged in sofa snake spring to install

Technical Field

The utility model relates to a sofa installation accessory field especially relates to a pintle subassembly that is arranged in sofa snake spring installation.

Background

The sofa is a chair with cushions. In order to ensure the comfort of the sofa, a spring is arranged in the sofa, and then a flexible sponge is arranged on the spring. The spring used in the sofa is generally a serpentine spring, which is an important component in the sofa structure, and the serpentine spring is also called an S spring or a tension spring, and is generally called a serpentine spring because it is shaped like a letter S and has a tensile property.

When the sofa is installed with the serpentine spring on site, the fastening nails are gradually installed on the sofa frame, and then the two ends of the serpentine spring are respectively hooked on the fastening nails. When sofa furniture is purchased in the existing market, the sofa is usually transported in a split state in order to facilitate the transportation of the sofa. When transported to the home of a purchaser, the sofa is assembled and practical at home. In the installation process, the fasteners are in a bulk state, so that the distance between the fasteners is difficult to hold, and the bulk fasteners are easy to be lacked during packaging and lost during field installation. Accordingly, there is room for improvement in prior art fastener packaging arrangements.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a pintle subassembly for installation of snake spring in sofa, the installation of pintle on the sofa frame of can being convenient for can avoid the pintle to lack or the problem of losing again.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the connecting belt comprises a connecting belt and a plurality of cramps which are arranged along the length direction of the connecting belt and are inserted on the connecting belt;

the clasp nail is provided with a hook groove for hooking the end of the snake spring and a plug-in sheet which passes through the connecting belt and can be installed in the sofa frame.

Preferably, the utility model discloses set up further as, the cell wall of hook groove turns over outwards and forms spacing limit.

Preferably, the utility model discloses set up further as, the inserted sheet is located the notch department of hook groove to the root of inserted sheet sets up to the top of inserted sheet outwards bending gradually.

Preferably, the utility model discloses further set up to, hook groove and inserted sheet are integrated into one piece structure.

As preferred, the utility model discloses further set up to, the connecting band is the paper tape.

Compared with the prior art, the utility model has the advantages that: the fastening nails are all inserted into the connecting belt, so that the field installation of the fastening nail assembly is facilitated, and the problem that the fastening nails are absent or lost can be avoided.

fig. 2 is a side view of the present embodiment of the present invention showing a cleat assembly for mounting a serpentine spring in a sofa.

Detailed Description

The buckle pin assembly for installing the serpentine spring in the sofa according to the present invention will be further described with reference to fig. 1 to 2.

The utility model provides a pintle subassembly that is arranged in sofa snake spring to install which characterized in that: comprises a connecting belt 2 and a plurality of cramps 1 which are arranged and inserted on the connecting belt 2 along the length direction of the connecting belt 2. Normally, the distance between every two adjacent fasteners 1 on the connecting belt 2 is the same, except for other requirements. The clasp 1 has a hook slot 12 for hooking the end of the serpentine spring and a tab 11 passing through the connecting strap 2 and able to be inserted into the sofa frame.

As a preferred embodiment, the present embodiment is further configured that the insert 11 has two pieces and is located at the notch of the hook groove 12, and the root of the insert 11 to the top of the insert 11 are gradually bent outward. After the insertion pieces 11 are bent outwards, the fastening nails 1 can be prevented from falling off from the connecting bands 2, and the strength of the fastening nails 1 inserted into the sofa frame can be improved.

In a preferred embodiment, the groove wall of the hook groove 12 at the notch is further folded outwards to form a limiting edge 121. The limiting edge 121 can limit the insertion depth of the insertion sheet 11 on the connecting band 2 so as to ensure the assembly regularity of the plurality of fasteners 1 on the connecting band 2; on the other hand, after the fastening nail 1 is inserted into the sofa frame through the insertion piece 11, the limiting edge 121 can also play a limiting role to limit the insertion depth of the fastening nail 1, so as to ensure the neatness of the fastening nail 1 on the sofa frame.

As a preferred embodiment, the present embodiment is further configured such that the hook slot 12 and the insert 11 are formed integrally, so as to facilitate the integrally formed production of the fastening nail 1.

As a preferred embodiment, the present embodiment is further configured that the connecting strip 2 is a paper strip. The paper tape is not only low in cost, but also convenient to use, namely, when the paper tape is used on site, a user can tear the paper tape conveniently to select the mesh belt with the corresponding size.

As a preferred embodiment, the present embodiment is further configured such that the width of the paper tape is smaller than the width formed by the two position-limiting edges 121, and this structure can hide the paper tape.

When the utility model is produced, the cramp 1 is inserted onto the paper tape by mechanical equipment or manpower, and then the inserting piece 11 is bent by a mechanical tool; when the length of the paper tape is selected, the length of the side where the cramp 1 needs to be inserted on the sofa frame is selected. When the on-site installation, the sofa frame need the limit of installation cramp 1 directly select to correspond length and be equipped with the connecting band 2 of cramp 1, then pack into the edge that the sofa frame corresponds with cramp 1 on the connecting band 2, carry out this operation in proper order, can correspond the edge with the sofa frame and install the utility model discloses, have easy operation's characteristics, need not to consider the interval between cramp 1 promptly, can also avoid cramp 1 to lack or be the problem of loss simultaneously.

In order to further promote the installation convenience, the sofa frame is provided with the spout that extends along this length of side degree direction on the edge that corresponds the installation cramp, and the installation can be accomplished in the direct tip notch that slides in from the spout of cramp subassembly.

Unless otherwise specified, in the present invention, if the terms "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, rather than to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, the terms describing orientation or positional relationship in the present invention are used for illustrative purposes only, and should not be construed as limiting the present patent, specific meanings of the above terms can be understood by those of ordinary skill in the art in light of the specific circumstances in conjunction with the accompanying drawings.
