Description

Screw anti-disengaging structure

Technical Field

The utility model relates to a screw anti-disengaging structure.

Background

The screw anti-disengaging on the market at present generally adopts from the screw to start, such as root polished rod anticreep screw, pressure riveting pine do not take off the screw etc. relatively speaking the screw price is more complicated than ordinary screw technology, the price is many times higher, the structure in addition adopts the oblique angle dog, impresses the screw in corresponding position, the assembly is troublesome and the dismantlement is difficult after the dress.

Disclosure of Invention

When being less to current screw installation space, the screw can be followed by the condition that mounting structure goes up to drop and cause the assembly inconvenience in the installation, the utility model provides a convenient and reliable's solution.

The utility model provides a technical scheme as follows:

a screw retaining structure, which is used for mounting a mounted structure through a screw; the mounting surface of the mounted structure is provided with a through hole, the mounted structure is provided with two stop rods or stop blocks, and a gap between the two stop rods or the stop blocks is positioned right above the through hole; when the screw is screwed into the through hole, the head of the screw is positioned between the lower end surface of the stop rod or the stop block and the mounting surface.

The utility model discloses the utilization is located the shelves pole or the dog directly over the through-hole as the mounting hole and is carried on spacingly to the screw, prevents that the screw from deviating from.

The stop lever or the stop block is fixed on the mounted structure through an elastic structural component.

Or the stop lever or the stop block is made of elastic materials.

Utilize the elasticity of shelves pole or dog, convenient assembly, elasticity resets simultaneously and restricts the activity of screw in the within range and is unlikely to deviate from, is applicable to the multiple screw of taking the screwhead.

Furthermore, the diameter of the through hole is slightly larger than the diameter of the thread excircle of the screw, so that the screw can keep a certain relative position relative to the mounted structure and is convenient to detach.

Furthermore, the screw can be a screw with a head larger than the thread diameter of the screw, such as a hexagon socket head or a cross head.

Further, the inner side of the stopper or the stopper rod is beveled or other structures are used for designing the screw guide structure.

Further, when the mounted structure is an injection molding part, a step is arranged on the mounting surface; when the mounted structure is a sheet metal structure, a sleeve is arranged at the mounting surface; the through hole is arranged at the step or the sleeve. The axial size of the through hole is longer through the design of process or structure, and the axial movement of the screw in the through hole can be limited so that the screw is basically vertical to the mounting surface.

Compared with the prior art, the utility model has the following advantages:

1) The utility model discloses screw anti-disengaging structure, low cost, design shelves pole and step can batch production when injection mould designs, and the mould cost can be neglected, only increases a small amount of injection moulding material cost, compares the present scheme economic nature high;

2) The utility model has reliable structure scheme, utilizes the elasticity of plastic materials to limit the screw to move in the range so as not to fall off, and is suitable for various screws with screw heads;

3) The utility model discloses screw anti-disengaging structure can carry out the people for tearing down, carries out a lot of utilization, has avoided dismantling the problem of difficulty because of special problem needs the dismantlement screw, avoids the waste that unnecessary leads to.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to fig. 4, the utility model relates to a screw anti-disengaging structure, include by mounting structure 1, screw 2, there is a through-hole by the installation face of 1 bottom of mounting structure, the axial dimensions of through-hole sets up longer, if the last design of injection structure has step 5, sheet metal structure punches a hole or various modes such as installation sleeve, the diameter of through-hole is a bit bigger than external diameter of screw simultaneously, effective length according to the length adjustment through-hole of screw, two parallel shelves pole 4 have been designed above step 5, if the injection molding directly moulds plastics, perhaps the sheet metal component punching press goes out the horizontal pole, the inboard design of shelves pole 4 has the oblique angle or utilizes other structural design screw guide structure, be convenient for the screwhead to get into between two poles, guarantee the through-hole of step earlier in of screw during the high position of design shelves pole, let the screwhead extrusion shelves pole get into shelves pole below again. When the mounting is carried out, the whole mounted structure 1 and the screw 2 can be mounted as an assembly (such as mounted on the structural member 3 shown in figures 3 and 4), and if special conditions exist, such as the screw is damaged and replaced, the screw can be taken out through manually separating the gear rod and replaced without damaging the mounted part.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
