Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt equipment, in particular to an anchor bolt for installing a basement. Background Art

[0002] Anchor bolts are the most common type of fasteners. They are mainly composed of expansion pieces and expansion sleeves. They rely on the friction generated by the expansion or the mechanical locking effect to connect the insulation system and the base wall. However, the existing basement anchor bolts have insufficient overall seismic resistance when fixing the walls, and are prone to loosening after being vibrated. Therefore, there is an urgent need for a basement installation anchor bolt to solve the above-mentioned problems. Utility Model Content

[0006] Preferably, the limiting device includes a fixed slide, a threaded sleeve is fixedly arranged at the center of the upper end surface of the fixed slide, six groups of guide grooves are equidistantly arranged on the side end surface of the fixed slide, and six groups of limiting clamps are equidistantly arranged on the lower end surface of the fixed slide.

[0007] Preferably, the buffer device comprises a guide slip ring, and six groups of connecting blocks are equidistantly arranged on the side end surface of the guide slip ring, and six groups of spring clamps are equidistantly arranged on the upper end surface of the guide slip ring.

[0008] Preferably, the threaded guide shaft is threadedly connected to the threaded sleeve, which can improve the stability of subsequent locking and limiting.

[0009] Preferably, the guide slip ring is slidably engaged with the fixed slide seat via the guide slot, the top end surface of the spring clamp ring is fixedly connected to the inside of the guide slot, and the guide slot can provide a sufficient guiding basis for the guide slip ring, thereby improving the stability of the subsequent upward and downward sliding displacement of the buffer device inside the fixed slide seat.

[0010] Preferably, the conical clamping shaft is fitted and connected to the limiting clamping plate, so as to facilitate the subsequent stable limiting of the limiting clamping plate inside the mounting hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides a limit device and a buffer device. When performing a locking operation, the connecting block can cooperate with the external connecting piece to perform positioning and locking. At the same time, the six sets of spring clamps can cooperate with the guide sliding ring to slide up and down inside the fixed slide, which is convenient for providing a sufficient up and down displacement basis for the fixed slide in a vibrating state, thereby improving the stability of the subsequent limit card plate in limiting the position inside the building.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a basement installation anchor bolt, including a hexagonal rotating plate, a threaded guide shaft, a tapered clamping shaft, a limiting device and a buffer device.

[0020] The inner end face of the limiting device is threadedly connected to a threaded guide shaft for limiting, and a hexagonal rotating plate is fixedly arranged at the center of the upper end face of the threaded guide shaft, a conical clamping shaft is fixedly arranged at the center of the lower end face of the threaded guide shaft, and a buffer device is arranged near the top of the outer end face of the limiting device.

[0021] Preferably, the limiting device includes a fixed slide, a threaded sleeve is fixedly arranged at the center of the upper end surface of the fixed slide, six groups of guide grooves are equidistantly arranged on the side end surface of the fixed slide, and six groups of limiting clamps are equidistantly arranged on the lower end surface of the fixed slide.

[0022] Preferably, the buffer device comprises a guide slip ring, and six groups of connecting blocks are equidistantly arranged on the side end surface of the guide slip ring, and six groups of spring clamps are equidistantly arranged on the upper end surface of the guide slip ring.

[0023] Preferably, the threaded guide shaft is threadedly connected to the threaded sleeve, which can improve the stability of subsequent locking and limiting.

[0024] Preferably, the guide slip ring is slidably engaged with the fixed slide seat via the guide slot, the top end surface of the spring clamp ring is fixedly connected to the inside of the guide slot, and the guide slot can provide a sufficient guiding basis for the guide slip ring, thereby improving the stability of the subsequent upward and downward sliding displacement of the buffer device inside the fixed slide seat.

[0025] Preferably, the conical clamping shaft is fitted and connected to the limiting clamping plate, so as to facilitate the subsequent stable limiting of the limiting clamping plate inside the mounting hole.

[0026] Working principle: Before use, the user can insert the limit card plate and the threaded guide shaft into the positioning hole to facilitate subsequent installation operations. Then the user can position the guide slip ring to the external mounting plate, and then insert the external connecting piece into the connecting card block until the guide slip ring is connected to the mounting plate. When tightening, the user can insert the external tool into the hexagonal swivel plate and then rotate it. The hexagonal swivel plate can drive the conical card shaft to retract through the threaded guide shaft, and then the conical card shaft can synchronously drive the four groups of limit card plates to move outward, so that the four groups of limit card plates can be locked in the mounting holes. When the buffer device and the limit device vibrate, the six groups of spring clamps can cooperate with the guide slip ring to slide up and down inside the fixed slide, which is convenient for the subsequent provision of sufficient up and down displacement basis for the fixed slide in a vibrating state to prevent the limit device inside the mounting hole from falling off and affecting the stability of the limit.
