Technical Field

The utility model relates to the technical field of screw rods, in particular to an improved screw rod fixing structure.

Background

When motor and lead screw lug connection, then use the shaft coupling, the fixed mode of present lead screw is: the screw rod input end is processed with screw threads, the screw rod passes through the two space rings and the screw rod supporting seat, the screw threads of the screw rod are locked with a fastening nut, one end of the fastening nut is leaned against the end surface of the space ring after being fixed, and a fastening screw hole is arranged in the fastening nut and used for preventing the fastening nut from loosening after the fastening screw is screwed down; this kind of fixed mode need be processed on the lead screw and have the opening for screw up fastening nut after inserting the spanner, and the installation is inconvenient, and fastening nut has the risk that becomes flexible and drop.

Accordingly, one skilled in the art provides an improved lead screw fixing structure to solve the problems set forth in the background art.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an improved high-voltage wire dividing groove with a screw rod fixing structure, which aims to solve the problems in the background technology.

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

the utility model provides an improved generation lead screw fixed knot constructs, includes the base, the internally mounted of base has the lead screw main part, and the inside equidistance rigid coupling of base has the space ring, and the wedge ring has been cup jointed to the surface of lead screw main part, and the internally mounted of base has the clamping ring, and the shaft coupling is installed to the one end of lead screw main part, and the surface mounting of base has the lead screw fixing base, and the lead screw supporting seat is still installed on the surface of base.

As a still further scheme of the utility model: the number of space ring is two, and all runs through and install the surface at the lead screw main part.

As a still further scheme of the utility model: the quantity of clamping ring is two, and the clamping ring is semi-circular, and the surface of clamping ring runs through and installs the screw.

As a still further scheme of the utility model: the lead screw main body is installed in the inside of lead screw fixing base and lead screw supporting seat all runs through.

As a still further scheme of the utility model: the interior of the wedge-shaped ring is conical, and the outer surface of the pressing ring is conical.

As a still further scheme of the utility model: the surface of the screw rod main body is provided with a clamping groove.

Compared with the prior art, the utility model has the beneficial effects that:

1. this practicality type, through setting up wedge ring and clamping ring, when wedge ring and clamping ring are the contact of toper face, and the draw-in groove on the lead screw with clamping ring rigidity, the clamping ring can not be to the reverse direction removal of wedge ring, therefore the lead screw is fixed not have not had not hard up possibility, has strengthened stability, has strengthened the practicality.

In the figure: 1. a base; 2. a screw rod fixing seat; 3. a screw rod supporting seat; 4. a lead screw body; 5. a coupling; 6. a wedge ring; 7. pressing a ring; 8. and a space ring.

Detailed Description

Example 1

As shown in fig. 1, 2 and 3, an improved lead screw fixing structure comprises a base 1, a lead screw main body 4 is installed inside the base 1, a clamping groove is formed in the surface of the lead screw main body 4, spacer rings 8 are fixedly connected to the inside of the base 1 at equal intervals, the number of the spacer rings 8 is two, and the spacer rings are installed on the outer surface of the lead screw main body 4 in a penetrating manner, a wedge-shaped ring 6 is sleeved on the outer surface of the lead screw main body 4, a pressing ring 7 is installed inside the base 1, the number of the pressing rings 7 is two, the pressing rings 7 are semicircular, the inside of the wedge-shaped ring 6 is conical, the outer surface of the pressing ring 7 is conical, a screw is installed on the outer surface of the pressing ring 7 in a penetrating manner, a coupler 5 is installed at one end of the lead screw main body 4, a lead screw fixing seat 2 is installed on the surface of the base 1, a lead screw supporting seat 3 is also installed on the surface of the base 1, the lead screw fixing seat 2 and the lead screw main body 4 is installed in a penetrating manner inside of the lead screw supporting seat 3, this practicality type, through setting up wedge ring 6 and clamping ring 7, when the conical surface contact of wedge ring 6 and clamping ring 7, and the draw-in groove on the lead screw main part 4 with clamping ring 7 rigidity, clamping ring 7 can not be to the reverse direction removal of wedge ring 6, therefore lead screw main part 4 is fixed not to have not had not hard up possibility, has strengthened stability, has strengthened the practicality.

The working principle of the utility model is as follows: when the lead screw is installed, the input end of the lead screw main body 4 passes through the lead screw supporting seat 3 and the inner centers of the two spacing rings 8, the lead screw main body 4 is fixed to be installed through the clamping groove on the lead screw main body 4, the pressing ring 7 and the wedge-shaped ring 6, when the lead screw is fixed, the wedge-shaped ring 6 passes through the input end of the lead screw main body 4 and is close to the spacing rings 8, the inner conical surfaces of the two semicircular pressing rings 7 are contacted with the conical surfaces on the wedge-shaped ring 6, the pressing ring 7 can automatically place the blocking edge into the clamping groove on the lead screw main body 4, the screws on the two pressing rings 7 are locked, the wedge-shaped ring 6 is automatically pressed with the spacing rings 8 under the action of the pressing ring 7, and the lead screw main body 4 is fixed, through the arrangement of the wedge-shaped ring 6 and the pressing ring 7, when the wedge-shaped ring 6 is contacted with the conical surfaces of the pressing ring 7, the position of the pressing ring 7 is fixed, and the pressing ring 7 can not move towards the opposite direction of the wedge-shaped ring 6, therefore, the lead screw main body 4 is fixed without looseness, the stability is enhanced, and the practicability is enhanced.

The foregoing shows and describes the general principles, principal features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, and such changes and modifications are within the scope of the utility model as claimed.
