Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, 2 and 3, the present invention provides a locking bolt device, which comprises a base material 3, a bolt 2 connected in the base material 3, the upper surface of the base material 3 is connected with a medium pad 5, one end of the bolt 2 far away from the base material 3 is connected with a clamping nut 1, the bolt 1 can be specially made by manufacturers, the bolt 2 can be specially made by manufacturers as a matched product without limitation, the surface of one side of the medium pad 5 close to the clamping nut 1 is provided with a lock tongue hole 501, the inner diameter of the lock tongue hole 501 is larger than the outer diameter of the lock tongue 401, and the lock tongue hole 501 can be selectively formed on the cushion 5 or the substrate 3, can select according to the user demand in the in-service use the locking bolt hole 501 is provided with the locking subassembly 4 that fastens spacing and prevent that screens nut 1 is stolen to screens nut 1.

Specifically, as shown in fig. 1, 2 and 3, the retaining nut 1 includes a nut main body 101, a bolt hole 104 is opened on the nut main body 101, the bolt hole 104 is used for being screwed with the bolt 2, the bolt hole 104 is provided with a nut flange surface 102 and an annular saw tooth 103 for clamping the locking assembly 4 on one side surface close to the bolt 2, and the annular saw tooth 103 is located outside the nut flange surface 102, so as to facilitate subsequent disassembling operation of a user.

When the clamping nut 1 is used, firstly, the bolt 2 is fixed on the substrate 3 (the fixing mode can be selected to be welded or connected by screw threads), then the locking component 4 is plugged into the locking tongue hole 501 on the dielectric pad 5 or the substrate 3 (at this time, the locking tongue 401 can protrude out of the locking tongue hole 501), then, the clamping nut 1 is sleeved on the bolt 2, and then, the locking component 4 rotates again, namely, when the locking component 4 rotates, because the locking component 4 comprises the locking tongue 401, one end of the locking tongue 401 far away from the clamping nut 1 is provided with the elastic spring 402, and the side wall of the locking tongue 401 is provided with the movable insertion hole 403, once the annular saw tooth 103 on the lower surface of the clamping nut 1 contacts the locking tongue 401, the tooth tip of the first saw tooth can press the locking tongue 401 into the locking tongue hole 501, and once the first saw tooth is separated from the locking tongue 401, the elastic spring 402 can rapidly reset to enable the locking tongue 401 to be clamped between the first saw tooth and the, because of the sawtooth is the triangle-shaped structure, if user's reversal screens nut 1 this moment, screens nut 1 can be blocked by locking tongue 401 for the user can only corotation with screens nut 1 cover on bolt 2, thereby avoided not hard up and the condition of being stolen to take place, and has seted up movable jack 403 because of the lateral wall of locking tongue 401, so locking tongue 401 is stirred to tiny rod-shaped thing such as user's accessible contact pin, makes it slide into lock tongue hole 501, and breaks away from with the sawtooth, then can dismantle screens nut 1.

Furthermore, the ring-shaped saw teeth 103 include a closed ring-shaped saw tooth for preventing theft and an open ring-shaped saw tooth for preventing loosening of the clamping nut 1, in order to set the device in two forms, wherein one is a detachable device of the clamping nut 1 with the open ring-shaped saw tooth, which is used for anti-loose or anti-theft purpose and can be used repeatedly by the user, while the other is a disposable locking device of the clamping nut 1 with the closed ring-shaped saw tooth, which is specially used for anti-theft purpose, i.e. the locking tongue hole 501 on the locking tongue 401 is blocked by the closed ring-shaped saw tooth, so that the user can not insert a pin, i.e. the device can be used only once, and when the device is used, the workload and the installation difficulty can not be increased due to the locking component 4, the device can be operated as a common screw, after the device is tightened, the clamping force can, the daily maintenance of common screws is omitted, the expense is reduced, and the labor capacity is saved.

As shown in fig. 4, 5, 6 and 7, the dielectric pad 5 includes a round dielectric pad with a clamping position 505, a special-shaped clamping dielectric pad 502, a connecting dielectric pad 503 and a ring-shaped dielectric pad 504, so that a user can select the dielectric pad according to different use requirements and different economic costs.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
