Problems solved by technology
First of all, it is necessary to insert the bolts from the open end of the keel groove, and the bolts can only be installed in the bolt grooves, which not only makes the installation very troublesome, but also has to be disassembled when the two ends of some keels are closed. open keel
Secondly, when the nuts are screwed, the bolts are also easy to rotate, making installation difficult

The invention relates to attachment bolts, in particular to an operation room wallboard keel attachment bolt, comprising a bolt rod, bolt threads, a thread head, a first chamfer, a first raised head, a second raised head, a third raised head, a fourth raised head, a second chamfer, a fifth raised head, a sixth raised head, a wallboard keel and a bolt slot; the bolt rod and the bolt head are vertically fixedly connected; and the bolt threads are made on the bolt rod. The operation room wallboard keel attachment bolt has the advantages that the bolt can be mounted at any position of the bolt slot as the bolt head is manufactured to be square; the bolt head is provided with multiple levels of limiting raised heads, which can be adjusted according to the width in the bolt slot; and the attachment bolt is simple in making and mounting and easy for production and operation.
Description
technical field [0001] The invention relates to a connecting bolt, in particular to a connecting bolt for a wall board keel in an operating room. Background technique [0002] The bolts used now generally adopt outer hexagonal bolts. This structure has many shortcomings in the use of building the wall keel of the operating room. First of all, it is necessary to insert the bolts from the open end of the keel groove, and the bolts can only be installed in the bolt groove. Open the keel. Secondly, when the nut is screwed, the bolt is also easy to rotate, which makes installation difficult. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, adopt a kind of operating room wall panel keel connecting bolt, utilize the bolt head to make rectangular parallelepiped and install the multi-stage limit protrusion, can prevent the bolt from rotating, making and installing Simple and easy to operate. [0004] In order t...
