Detailed Description
As shown in figure 1, the novel ceiling bolt fastening device comprises an expansion link 1, and a fastening piece 2 is installed at the top end of the expansion link 1.
As shown in fig. 2 to 4, the telescopic rod 1 includes a first hollow tube 1.1 and a second hollow tube 1.2, and the first hollow tube 1.1 and the second hollow tube 1.2 are both tubular structures with regular hexagonal cross sections. Because the first hollow pipe 1.1 and the second hollow pipe 1.2 are both in a regular hexagon tube structure, the first hollow pipe 1.1 and the second hollow pipe 1.2 cannot rotate circumferentially relatively. The outer diameters of the first hollow pipe 1.1 and the second hollow pipe 1.2 are not more than 6cm, and the wall thickness is not more than 1cm. The second hollow tube 1.2 is sleeved with the first hollow tube 1.1 and keeps a sliding fit relation. A clamping mechanism 1.3 is fixed on the second hollow pipe 1.2, a plurality of grooves are correspondingly arranged on the side wall of the corresponding first hollow pipe 1.1 at intervals along the axial direction, and after the first hollow pipe 1.1 moves up and down relative to the second hollow pipe 1.2 to be in place, the clamping mechanism 1.3 is clamped in the corresponding groove.
As shown in fig. 2-3, the clamping mechanism 1.3 includes a locking sleeve 1.3.1, the outer side wall of the locking sleeve 1.3.1 is provided with a thread, and the locking sleeve 1.3.1 is in threaded connection with the corresponding transverse through hole 1.3.2 on the second hollow tube 1.2 through the external thread. A pressure spring 1.3.3 is arranged in the locking sleeve 1.3.1, the other end of the pressure spring 1.3.3 is connected with a clamping ball 1.3.4, and the clamping ball 1.3.4 is clamped into a groove 1.3.5 of the first hollow pipe 1.1.
As shown in fig. 2, when the upper and lower positions are adjusted, the ball 1.3.4 is disengaged from the groove 1.3.5, the ball 1.3.4 and the compression spring 1.3.3 are pressed into the transverse through hole 1.3.2, and the compression spring 1.3.3 is in a compressed state. As shown in fig. 4, after the up-down adjustment is in place, the locking ball 1.3.4 is locked with the groove 1.3.5, and the pressure spring 1.3.3 extends out to reset and tightly pushes the locking ball 1.3.4.
As shown in fig. 5, the fastening member 2 includes a fastening body 2.1, the fastening body 2.1 is also a tubular structure with a cross section being a regular hexagon, and the fastening body 2.1 is sleeved with the first hollow tube 1.1 and is clamped by a clamping mechanism 1.3. The structure and the principle of the clamping mechanism 1.3 are the same as those of the clamping mechanism 1.3 on the telescopic rod 1. The top end of the fastening main body 2.1 is provided with a positioning flat plate 2.2, and the positioning flat plate 2.2 can be attached to a ceiling to realize vertical positioning of the telescopic rod 1. The center of the fastening main body 2.1 is provided with a clamping groove 2.3, the cross section of the clamping groove 2.3 is in a regular hexagon shape, and the size of the clamping groove 2.3 is matched with the corresponding ceiling bolt 3.
Preferably, as shown in fig. 6, the top end of the fastening body 2.1 at the clamping groove 2.3 is smoothly transited to a tapered counterbore 2.4. Because people operate on the ground, the observation is difficult, the end face of the clamping groove 2.3 is flat, the cross section is regular hexagon, and the state that each side of the clamping groove 2.3 is parallel to and right against each side of the suspended ceiling bolt 3 is difficult to adjust. Through setting up a taper hole 2.4, taper hole 2.4 is great relatively and for the toper, can make in furred ceiling bolt 3 stretches into taper hole 2.4 fast, can make draw-in groove 2.3 just right with furred ceiling bolt 3 through adjusting telescopic link 1 to vertical state, through rotatory telescopic link 1 and slightly upwards the application of force, can block into simple and convenient fast when draw-in groove 2.3 each limit is parallel with furred ceiling bolt 3 each limit.
As shown in fig. 9, a handle 1.4 is installed at the bottom of the telescopic rod 1, and the handle 1.4 is cross-shaped. Thereby facilitating manual operation.
The working principle and the process are as follows:
step1: firstly, a proper fastener 2 is selected to be inserted into the top of the telescopic rod 1, locking can be completed through the clamping mechanism 1.3, and then the length of the telescopic rod 1 is adjusted according to the height of the suspended ceiling in a construction site.
Step2: the telescopic rod 1 is adjusted to be in a vertical state, the clamping groove 2.3 on the fastener 2 is aligned with the ceiling bolt 3 on the ceiling, the clamping groove 2.3 is sleeved in the ceiling bolt 3, and the positioning flat plate 2.2 is basically contacted with the ceiling.
Step3: and then, the handle 1.4 is rotated by hand, the ceiling bolt 3 is gradually screwed, after the ceiling bolt is screwed in place, the screwing condition of the ceiling bolt 3 is checked, the device is shifted to the next ceiling bolt 3 to be screwed after the confirmation of no error, and the operation is repeated.
