Abstract
The utility model discloses a stamping scaffold fastener. The stamping scaffold fastener comprises a lower cover and is characterized by further comprising an upper cover and a screw. One end of the lower cover is connected with the bottom of the upper cover through a hinge pin. The other end of the lower cover is connected with the bottom of the screw through a hinge pin. Two clamp feet are arranged on the top of the upper cover. An opening is formed between the two clamp feet. A boss is arranged in the middle of the screw. Threads are arranged on a portion, above the boss, of the screw. The spacing of the opening is larger than the diameter of the screw and smaller than the spacing between two sides of the boss. The stamping scaffold fastener solves the problems in the prior art that the stamping scaffold fastener is long in installation time and low in efficiency, and can bring large loss due to the fact that the stamping scaffold fastener is prone to be integrally scraped. The stamping scaffold fastener is simple in structure, convenient to use, fast in installation speed and long in service life, and has a protection function.
Description
Technical field
The utility model relates to a kind of building facilities apparatus, particularly relates to a kind of punching press scaffold clasp.
Background technology
Fastener is the middle part that links that connects rail and sleeper.Its effect is that rail is fixed on sleeper, keep gauge and stop rail with respect to sleeper in length and breadth to movement.On the track of concrete sleeper, because the elasticity of concrete sleeper is relatively poor, fastener also need provide enough elasticity.For this reason, fastener must have enough intensity, durability, and certain elasticity, and effectively keep reliable link between rail and sleeper.In addition, also require the fastener system part few, install simply, be convenient to dismounting.
Present punching press scaffold clasp, screw is long, and the screw thread that arranges on screw is also more, screws by nut the time that fastener rotates so just long, causes the fastener set-up time long, and efficient is low.When simultaneously the user screws upper cover by nut, often in order to reach fastening effect preferably, nut down can be rotated with strength and screw, tend to like this cause upper cover stressed excessive, the fracture damage that causes upper cover causes scrapping of whole fastener, has brought larger loss.
The utility model content
In order to solve punching press scaffold clasp in prior art; set-up time is long; efficient is low; and whole fastener is easily scrapped, and brings the problem of greater loss, and it is a kind of simple in structure that the utility model provides; easy to use; installation rate is fast, has defencive function, the punching press scaffold clasp that application life is long.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of punching press scaffold clasp, comprise lower cover, it is characterized in that: also comprise upper cover and screw, an end of described lower cover is connected by joint pin bottom upper cover, and the other end of described lower cover is connected by joint pin bottom screw, be provided with two card bases at the top of upper cover, leave opening between two card bases, be provided with boss at the middle part of screw, be provided with screw thread on the thread part above boss, the spacing of described opening is greater than the diameter of screw, less than the spacing of boss both sides.
Aforementioned a kind of punching press scaffold clasp is characterized in that: described boss is round boss.
Aforementioned a kind of punching press scaffold clasp is characterized in that: the bottom of described lower cover is connected with one threaded connecting rod is set.
Aforementioned a kind of punching press scaffold clasp is characterized in that: the top of described two card bases is bent to form respectively flanging to the inside.The beneficial effects of the utility model are: the utility model punching press scaffold clasp has that card is held solid, safe ready tightly, interchangeability is arranged, the characteristics such as durable in use.The spacing of the utility model card base opening is greater than the diameter of screw, less than the spacing of boss both sides.After screw stretches between two card bases like this, nut can rotate on the screw thread of screw upper cover is compressed downwards, and boss can limit the card base of upper cover and continues mobile downwards, guaranteed not too deformation and damaging of upper cover, the cooperation by nut and boss simultaneously also can make fastener reach locking effect preferably.
Description of drawings
Fig. 1 is the utility model punching press scaffold clasp open mode schematic diagram.
Fig. 2 is the utility model punching press scaffold clasp buckling state schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Fig. 1-2, a kind of punching press scaffold clasp, comprise lower cover 1, upper cover 2 and screw 3, one end of lower cover 1 is connected by joint pin with upper cover 2 bottoms, the other end of lower cover 1 is connected by joint pin with screw 3 bottoms, be provided with two card bases 4 at the top of upper cover 2, leave opening 10 between two card bases 4, be provided with round boss 5 at the middle part of screw 3, be provided with screw thread 6 on screw 3 parts above round boss 5, the spacing of opening 10 is greater than the diameter of screw 3, less than the diameter of round boss 5.The bottom of lower cover 1 is connected with one threaded connecting rod 7 is set.The top of described two card bases 4 is bent to form respectively flanging 8 to the inside, and flanging 8 more is conducive to the card base 4 that round boss 5 props up upper cover 2, guarantees that fastener can be locked on steel pipe preferably.
The utility model punching press scaffold clasp fastens steel pipe by lower cover 1 and upper cover 2 in use.Then screw 3 is extend between 2 two card bases 4 of upper cover, recycling nut 9 rotates by the screw thread 6 on screw 3 upper cover 2 is compressed downwards, when the flanging 8 of two card bases 4 touches round boss 5, upper cover 2 just can not continue mobile downwards, guaranteed not too deformation and damaging of upper cover 2, the cooperation by nut 9 and round boss 5 simultaneously also can make fastener reach locking effect preferably.
The utility model lower cover 1 is taken to upper cover 2 card base 4 opening parts by screw 3 obvolvent steel pipes, thereby reaches the function of filling the span of a man's arms after fastening nut 9, realizes the purpose of holding steel pipe tightly.Boss 5 parts on the utility model screw 3 fully play locking, and position-limiting action plays rest upper cover 2 simultaneously, prevent upper cover 2 distortion, the crooked loosening effect of joint pin, thus effectively play the firm and indeformable purpose of fastener of clamping, easy to install.
Above demonstration and described basic principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
