The utility model comprises an upper handle and a lower handle which can be connected in a pivoting mode by a pivot shaft, wherein one end of the upper handle adjacent to the pivot shaft forms a fork shape; a furcation at one side forms a push rod, and the furcation at the other side is connected with a roller; one end of the lower handle adjacent to the pivot shaft forms a clamping head seat; the bottom part of the lower handle adjacent to the end forms a clamping head sheath; the bottom part of the lower handle behind the clamping head sheath forms a guide face; the utility model also comprises a clamping head; the clamping head is arranged in the clamping head sheath, and can be moved along axial direction in the clamping head sheath; one end of the clamping head aligns the clamping head seat, and the other end of the clamping head aligns the roller, wherein one end of the clamping head aligning the clamping head seat forms a sharp corner, the end part of one end of the clamping head aligning the roller forms a push plate and the push rod can be abutted to the push plate. The apparatus has the advantages of small volume, convenient carrying and simple operation in use. The operation of the fastening apparatus is finished only by a mechanical structure so that electrical energy is not required, and the utility model is particularly suitable for the condition of no power in a construction site.

Description

No screw interlock fastener

Technical field

The utility model relate to a kind of in interior architecture decoration construction, be used to connect the keel partition wall do not have screw interlock fastener energetically, relate to a kind of in interior architecture decoration engineering especially, when carrying out partition wall, centre keel and world keel intersect and to use joint portion that this device extend into both in addition interlock and fastening device when being connected together.

Background technology

At present, at home and abroad build, decorate in the construction work, the connection of being carried out when the use keel are made partition wall all needs the fastening mode of screw is adopted in keel boring again, its efficient is low, cost is high, operation easier is big during connection, surface dislocation, not straight and even, and screw loosening takes place easily, defective such as come off.

Summary of the invention

The purpose of this utility model is to provide a kind of no screw interlock fastener, this device volume is little, easy to carry, simple to operate during use, and the operation of this fastener only finished by frame for movement and need not utilize electric energy, is particularly useful for the power free situation in job site.

For achieving the above object, the utility model provides a kind of no screw interlock fastener, it is characterized in that, comprise the upper handle and the lower handle that link together pivotly by pivot, one end of the close described pivot of described upper handle forms forked, one side bifurcated forms push rod, and the opposite side branch is stuck and connected a roller; Described lower handle forms base of the carrier head near an end of described pivot, forms a chuck cover in the described lower handle bottom near this end, and a spigot surface is formed on the described lower handle bottom at described chuck cover rear; Also comprise a chuck, described chuck is arranged in described chuck cover and can moves vertically therein, one end of described chuck is aimed at described base of the carrier head, the other end of described chuck is aimed at described roller, the end that wherein said chuck is aimed at described base of the carrier head forms wedge angle, the end end that described chuck is aimed at described roller forms push pedal, and described push rod can be against described push pedal.

Nationality is by said apparatus, the high efficiency of fastening keel sheet, the fast 2-3 of speed that bores construction than common employing screw doubly, simultaneously because the keel sheet is to be interlocked after the distortion and not need screw, therefore the defective that does not also exist screw to get loose is particularly suitable for the steel plate of fastening 5 millimeter thickness.In addition, the chuck that the utility model fastener is adopted can be changed easily, so fastener has very long service life.

Description of drawings

Fig. 1 is the structural representation that the utility model does not have screw interlock fastener, and chuck is not worked;

Fig. 2 is an interlock fastener embodiment illustrated in fig. 1, and wherein chuck is in running order;

Fig. 3 be embodiment illustrated in fig. 1 in used chuck stereogram.

The specific embodiment

As shown in Figure 1 and Figure 2, no screw interlock fastener profile of the present utility model is similar to a clamp, comprise the upper handle 2 and the lower handle 3 that link together pivotly by pivot 1, one end of the close pivot 1 of upper handle 2 forms forked, one side bifurcated forms push rod 21, and the opposite side branch is stuck and connected a roller 22; Simultaneously, lower handle 3 forms base of the carrier head 31 near an end of pivot 1, and forms chuck cover 32 in the bottom near this end, and a spigot surface 33 is formed on lower handle 3 bottoms that this chuck overlaps 32 rears.One chuck 4 passes chuck cover 32 and can overlap in 32 at chuck and axially move, one end of chuck 4 is aimed at base of the carrier head 31 and is movable to chuck end portion and is arranged in base of the carrier head 31, the other end of chuck 4 is aimed at roller 22, roller 22 can roll on the spigot surface 33 of lower handle bottom, when upper handle when pressing down, roller 22 can be moved to the left to promote chuck and move to base of the carrier head 31.

Again referring to shown in Figure 3, as seen an end of chuck 4 aligning base of the carrier head 31 forms sharp keen wedge angle 41, the end end that chuck 4 is aimed at roller 22 is formed with push pedal 42, and one section near push pedal 42 on the chuck 4 is that a planar section 43 moves with the push rod 21 that guides upper handle 2, and push rod 21 can leave base of the carrier head 31 to promote chuck 4 against push pedal 42.

Below careful the course of work that the utility model does not have screw interlock fastener described.As shown in Figure 1, fastener wherein is in not duty, and at this moment, chuck 4 is arranged in chuck cover 32 but leaves base of the carrier head 31 segment distance, and upper handle 2 and lower handle 3 are in open configuration.As shown in Figure 2, when needs are fixed together two keel sheet A, make the keel partition wall earlier between chuck wedge angle 41 and base of the carrier head 31, close up upper and lower handle, at this moment, upper handle 2 drives roller 22 and rolls left along the spigot surface 33 on the lower handle 3, and roller 22 is supporting the push pedal 42 of chuck end simultaneously and chuck is promoted to base of the carrier head 31 directions.Along with chuck 4 is moved to the left in chuck cover 32, chuck wedge angle 41 pushes keel partition wall A gradually until keel being headed in the base of the carrier head 31, and this moment, wedge angle 41 pierced through keel and push superimposed keel sheet tightly is interlocked.

Subsequently, upper and lower handle is opened, the push rod 21 of upper handle 2 is supporting the push pedal 42 on the chuck 4 at this moment, along with upper and lower handle further opens, push rod 21 is pushing away push pedal 42 and is moving right, thereby be with chuck 4 to leave base of the carrier head 31, the most whole interlock fastener is withdrawn from the keel sheet, and the interlock of finishing superimposed keel sheet is fixed.

By the foregoing description as can be known, this device volume is little, easy to carry, and is simple to operate during use, and the operation of this fastener only finished by frame for movement and need not utilize electric energy, is particularly useful for the power free situation in job site.In addition, this fastener high efficiency, the fast 2-3 of speed that bores construction than common employing screw doubly, simultaneously because the keel sheet is to be interlocked after the distortion and not need screw, the therefore defective that does not also exist screw to get loose.In addition, the chuck that the utility model fastener is adopted can be changed easily, so fastener has very long service life.
