Abstract
The utility model belongs to the technical field of fasteners, and particularly relates to a locking screw for concrete wall pouring. The screw comprises a screw body and a nut, the screw body is provided with tooth screws, the nut comprises a nut body, a locking baffle is arranged in the nut body, and the lower portion of the locking baffle is connected to reverse tooth screws; a pulling bar penetrates the nut body to connect to the upper portion of the locking baffle, and a spring sleeves the pulling rod between the nut body and the locking baffle. The locking screw has the advantages of convenience in assembling and disassembling and low production cost.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of concrete wall and builds and use engaging screw mandrel.
Background technology
At present, when concreting body of wall or post, all need shuttering, between plate in template, need to be connected to form and to build chamber by screw mandrel, traditional screw mandrel, be to be fixed with silk cap, by rotating wire cap, to certain position, fix object, this method mostly completes by manual operations, twisting silk cap will take a long time, and can not increase work efficiency.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, and the concrete wall that easy installation and removal and cost of production are low is built and used engaging screw mandrel.
The purpose of this utility model is achieved like this: this screw mandrel comprises screw mandrel and silk cap, on screw mandrel, be provided with tooth silk, described silk cap comprises cap body, in cap body, be provided with locked catch, the bottom of locked catch is connected with reverse tooth silk, pull-up bar is connected with the top of locked catch through cap body, on the pull-up bar between cap body and locked catch, is set with spring.
Tooth silk on described screw rod is right-angled triangle, and limit of right-angled triangle and screw mandrel are at an angle of 90.The height of described tooth silk is not higher than the height of screw mandrel.Described locked catch is structure as a whole with reverse tooth silk.Described tooth silk is suitable with the tooth of reverse tooth silk.Described locked catch and pull-up bar are structure as a whole.
The utlity model has simple in structure, the advantage that easy installation and removal and cost of production are low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model screw mandrel;
Fig. 2 is the structural representation of the utility model silk cap.
The specific embodiment
As shown in Figure 1, 2, the utility model is that concrete wall is built and used engaging screw mandrel, this screw mandrel comprises screw mandrel 1 and silk cap, on screw mandrel 1, be provided with tooth silk 2, described silk cap comprises cap body 3, is provided with locked catch 4 in cap body 3, and the bottom of locked catch 4 is connected with reverse tooth silk 5, pull-up bar 6 is connected with the top of locked catch 4 through cap body 3, on the pull-up bar 6 between cap body 3 and locked catch 4, is set with spring 7.
Tooth silk 2 on described screw mandrel 1 is right-angled triangle.The height of described tooth silk 2 is not higher than the height of screw mandrel 1.Described locked catch 4 is structure as a whole with reverse tooth silk 5.Described tooth silk 2 is suitable with the tooth of reverse tooth silk 5.Described locked catch 4 and pull-up bar 6 are structure as a whole.
In use, by 6 pull-ups of pull-up bar, spring 7 is in contraction state for the utility model, silk cap sleeve is contained in to required fixing position on screw mandrel 1, and guarantees that tooth silk 2 is suitable with reverse tooth silk 5, now, put down pull-up bar 6, spring 7 stretches a cap is fixed on screw mandrel 1.Tooth silk 2 is designed to rectangular triangle, prevents back skating, and this kind of method saved the time of stubborn silk cap, can greatly increase work efficiency.
