Description

Carpet spreader with adjustable needle plate depth

technical field

The utility model relates to the decoration industry and belongs to carpet installation and laying tools.

Background technique

A carpet spreader, also known as a carpet spreader, is used to prevent wrinkles and bumps when carpet is laid. Due to the unreasonable structure of the traditional carpet spreader, the needle depth adjustment dial adopts the ordinary disc knob method, and the adjustment angle needs to be 360° to achieve the maximum adjustment length of the needle, and the operation is time-consuming and labor-saving.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a carpet spreader with adjustable needle plate depth, which saves time and labor when adjusting.

The purpose of this utility model is achieved in this way: the carpet spreader with adjustable needle plate depth includes a handle, the front end of the handle is provided with a head, the lower surface of the head is connected with a small needle plate, and the lower surface of the small needle plate is fixed For small needles, a rectangular installation groove is arranged in the head, and a rectangular large needle plate is arranged in the rectangular installation groove. Set the thread, the threaded section of the lifting shaft is threaded to connect the lifting shaft nut, the lifting shaft nut is connected with the large needle plate, the upper part of the lifting shaft extends out of the head and the handle, and then connects the gear adjustment wrench, and connects the spring column on the gear adjustment wrench Plug; a plurality of limit holes are set on the upper surface of the head, and the limit holes are used for positioning the telescopic end of the spring plunger.

As an improvement of the utility model, a scale label is provided on the upper surface of the head, and the scale label is arranged correspondingly to a plurality of limit holes.

As a further improvement of the utility model, a plurality of limiting holes are arranged in an arc of 180 degrees.

As a further improvement of the utility model, a wave washer is arranged on the lifting shaft between the head and the handle.

When adjusting, operate the spring plunger, the telescopic end of the spring plunger is out of the limit of the limit hole, and the gear position adjustment wrench is moved to drive the lifting shaft to rotate, so that the large needle plate is displaced on the lifting shaft to realize the movement of the large needle plate. Depth adjustment. The adjustment angle only needs to be 180 degrees to achieve the maximum adjustment length of the needle. The adjustment principle is that the lifting shaft adopts an 8-wire threaded shaft to realize the lifting of the needle plate. This adjustment method saves time and effort, and is convenient and quick.
