Problems solved by technology

The compression device with this structure needs to add pads with the same height as the sample when used, but the commonly used pads are often difficult to meet the needs of samples with different heights, so the applicability is low; The compression positioning is achieved through the surface contact between the bottom surface of one end and the upper surface of the sample. Therefore, it is necessary to increase the tightening torque of the compression nut to meet the positioning requirements of the sample, and the upper surface of the sample is an uneven surface. It is easy to loosen; in addition, if the tightening torque of the compression nut is too large, it is easy to cause the T-shaped screw to break, thereby reducing the reliability of the pressure plate.

Abstract

The invention discloses a toothed nail compressing device in a building engineering construction device. The toothed nail compressing device comprises a spring fixing base, a compressing device shell,a compressing device spring, a compressing device spring stabilizing column and an inverted U-shaped plate. The inverted U-shaped plate is positioned on the upper portion of a lantern ring lock nailand is fixedly connected with a center shaft of a toothed nail on the top of an adjusting mechanism; the spring fixing base is arranged on the upper portion of the inverted U-shaped plate, the bottomof the spring fixing base is fixedly connected with the inverted U-shaped plate, and the upper portion of the spring fixing base is fixedly connected with the compressing device spring; the upper endof the compressing device spring is fixedly connected with a spiral push rod of the toothed nail; the compressing device spring stabilizing column is arranged inside the compressing device spring, andthe diameter of the compressing device spring stabilizing column is smaller than that of the compressing device spring. The toothed nail compressing device has the advantages that the toothed nail compressing device is reasonable and compact in structure, low in application cost and convenient to adjust; the toothed nail compressing device is high in practicality, and fixing effects can be firmlyand quickly realized by the toothed nail compressing device; different construction devices can be fixed by the aid of the toothed nail compressing device, and accordingly the toothed nail compressing device is high in applicability.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a tooth nail pressing device in a construction device. Background technique [0002] In the current construction process of construction projects, it is usually necessary to use a pressing device to fix the construction device. At present, most of the commonly used pressing devices are pressing plates. The pressing plate generally includes a T-shaped screw arranged on the workbench, a flat-shaped pressing plate set on the T-shaped screw, and a flat plate set on the T-shaped screw and located above the pressing plate. compression nut. When in use, press one end of the pressure plate on the upper surface of the sample that is also placed on the workbench, add a pad under the other end of the pressure plate with the same height as the sample, and finally tighten the compression nut to compress the pressure plate . The compression device with this structure needs to...
