Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a quick detach split bolt, including a lead screw 1, the cover is equipped with shape and the equal same first sleeve pipe 2 of size and second sleeve pipe 3 on the lead screw 1, and the internal diameter of first sleeve pipe 2 and second sleeve pipe 3 all obtains the internal diameter than lead screw 1 big, and first sleeve pipe 2 and second sleeve pipe 3 are pasted tightly towards the terminal surface of one end each other.

Referring to fig. 2 and 3, an end surface of the first sleeve 2 facing the second sleeve 3 is provided with an annular first groove 21, and an end surface of the second sleeve 3 facing the first sleeve 2 is provided with an annular second groove 31. The main screw 1 is provided with an annular push ring 11, and the push ring 11 is fixedly connected with the main screw 1 (see fig. 5). The push ring 11 is disposed in the cavity formed by the first groove 21 and the second groove 31. Both ends of the main screw rod 1 are all sleeved with annular backing plates 4, the diameter of each backing plate 4 is larger than that of the first sleeve 2 and that of the second sleeve 3, and the main screw rod 1 is perpendicular to the two backing plates 4 respectively. All be provided with nut 5 on the lateral wall that two backing plates 4 deviate from each other, two nuts 5 are twisted on main screw 1 respectively soon.

When the split bolt needs to be disassembled, a worker firstly disassembles the two nuts 5 and the two base plates 4 at the two ends of the main screw rod 1, then lightly knocks the two ends of the main screw rod 1 along the length direction of the main screw rod 1 respectively, so that the push ring 11 pushes the first sleeve 2 and the second sleeve 3 respectively, and the first sleeve 2 and the second sleeve 3 are disassembled from the wall body.

Referring to fig. 1, in order to make the first sleeve 2 and the second sleeve 3 easier to be disassembled, the diameter of the first sleeve 2 is set to gradually decrease from the end away from the second sleeve 3 to the end towards the second sleeve 3, and the diameter of the second sleeve 3 is set to decrease from the end away from the first sleeve 2 to the end towards the first sleeve 2. Therefore, when a worker knocks the main screw rod 1, the first sleeve 2 and the second sleeve 3 can be completely separated from the wall body as long as the first sleeve 2 and the second sleeve 3 move along the length direction of the main screw rod 1, and therefore the first sleeve 2 and the second sleeve 3 can be detached from the wall body more easily.

Referring to fig. 2 and 4, the two ends of the main screw 1 are both sleeved with support rings 6, the two support rings 6 are connected with the main screw 1 in a sliding manner, the two support rings 6 are respectively located in the first sleeve 2 and the second sleeve 3, and the peripheral surfaces of the two support rings 6 are respectively attached to the peripheral surfaces of the first sleeve 2 and the second sleeve 3 in a sliding manner. Two support rings 6 can support final screw 1, and then guarantee final screw 1 and first sleeve 2 and third sleeve 3's axiality to make more stability to the split bolt.

When the two support rings 6 are respectively located in the first sleeve 2 and the second sleeve 3, the support rings 6 are not easily removed, for which purpose the two support rings 6 are respectively fastened to the mutually facing side walls of the two bearing plates 4. So that the support ring 6 can follow the movement of the shim plate 4.

Referring to fig. 3, in order to increase the sealing performance between the first sleeve 2 and the second sleeve 3, a sealing tube 211 with a circular cross section is fixedly connected to the bottom wall of the first groove 21 on the first sleeve 2, and an annular first elastic pad 311 adapted to the sealing tube 211 is fixedly connected to the bottom wall of the second groove 31 on the second sleeve 3. When the facing end surfaces of the first sleeve 2 and the second sleeve 3 are attached to each other, the sealing tube 211 compresses the first elastic pad 311, thereby making the sealing between the first sleeve 2 and the second sleeve 3 better.

The bottom wall of the first groove 21 and the bottom wall of the second groove 31 are fixedly connected with annular second elastic pads 7. When the staff dismantles first sleeve pipe 2 and second sleeve pipe 3 through knocking main screw 1, the vibration degree that takes place between first sleeve pipe 2 and the second sleeve pipe 3 can be reduced as far as to second cushion 7, and then reduces the influence to the wall body.

The implementation principle of the embodiment is as follows: when dismouting split bolt, the staff at first dismantles two nuts 5 and two backing plates 4 from the lead screw 1, then uses tools such as hammers to strike lead screw 1 gently in proper order to make first sleeve pipe 2 and second sleeve pipe 3 break away from in the wall body, then with first sleeve pipe 2 and second sleeve pipe 3 follow the wall body in the dismantlement can.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
