Abstract
The invention discloses plastic lock catches, which relate to plastic lock catches for assembling floors, and comprise floors and plastic frames arranged around the floors, wherein guide rail faces which contract inwards are arranged on the lower parts of the outer sides of the plastic frames; locking convex strips which are distributed at intervals and plastic sliding blocks of which the outer ends extend out of the guide rail faces are arranged on the guide rail faces; and guide grooves matched of the locking convex strips on corresponding assembled floors are formed on the plastic sliding blocks. The outer sides of the guide grooves of the plastic sliding blocks have a 15 to 25-degree slide-in angles; and reinforcing bars are arranged at the bottom of the plastic sliding blocks. After the slide-in angles reduce, the contact area between the guide grooves and the locking convex strips of other floors is increased, friction is increased and unlocking is avoided; and the reinforcing bars are arranged, so the strength of the plastic sliding blocks is improved and cracking is avoided radically.
Description
Technical field
The present invention relates to plastic rubber lock catch, specially refer to plastic rubber lock catch as assembled floor.
Background technology
Before the present invention proposes, nearly all wood floors, the tongue-and-groove form is all adopted in the assembly unit of composite floor board or consolidated floor.By machining, on the both sides, long limit on floor or corresponding position, process tenon shape or flute profile all around.Tenon shape and flute profile match, and each floor is connected with each other forms a smooth scene.The connection of adopting plastic lock catch to replace the tongue-and-groove form was once arranged, this plastic rubber lock catch, comprise the floor and the plastic cement frame is set around the floor, the guide pass of inside contraction is set in the bottom in the plastic cement frame outside, locking raised line and outer end are set on guide pass stretch out the plastic cement slide block of guide pass, the direction recess that the top setting of plastic cement slide block matches with locking raised line on the corresponding assembled floor.But planar design is adopted in the bottom of the plastic cement slide block in this plastic rubber lock catch, and strength deficiency in ground injustice or installation process are installed makes the plastic cement slide block very easily produce cracking, and it is loosening that the good floor of assembly unit is taken place.Making the angle of slipping into of the locking raised line insertion of another floor in addition on the plastic cement slide block is 30～60 °, and this angle is excessive, in use easily produces the dropout phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is to overcome deficiency of the prior art, a kind of plastic rubber lock catch, and the intensity of raising plastic cement slide block is avoided cracking phenomena; Strengthen the contact area of locking raised line and plastic cement slide block, avoid the phenomenon of threading off.
The present invention is achieved by the following technical measures.A kind of plastic rubber lock catch, comprise the floor and the plastic cement frame is set around the floor, the guide pass of inside contraction is set in the bottom in the plastic cement frame outside, locking raised line and outer end are set on guide pass stretch out the plastic cement slide block of guide pass, the direction recess that the top setting of plastic cement slide block matches with locking raised line on the corresponding assembled floor.There is the angle of slipping into that the locking raised line supplied with on the corresponding assembled floor slips into smoothly in the outside of the direction recess of described plastic cement slide block.The described angle of slipping into is 15～25 °; Bottom at the plastic cement slide block is provided with reinforcing rib.
The described angle of slipping into is 20 °.
Two reinforcing ribs are arranged in the bottom of described plastic cement slide block.
After the present invention adopts abovementioned technology,, strengthened the contact area of the locking raised line of direction recess and other plate, improved frictional force, avoided the dropout phenomenon slipping into after the angle reduces of the outside of the direction recess of plastic cement slide block; Bottom at the plastic cement slide block is provided with reinforcing rib, has improved the intensity of plastic cement slide block, has thoroughly avoided cracking phenomena; Guarantee the planeness and long-term use the on floor, reduced the maintenance work on floor.
Description of drawings
Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.
Among the figure: 1 is the floor, and 2 is the plastic cement frame, and 3 is guide pass, and 4 are the locking raised line, and 5 is the plastic cement slide block, and 6 is direction recess, and 7 for slipping into the angle, and 8 is reinforcing rib.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment: as shown in drawings, a kind of plastic rubber lock catch, comprise floor 1 and the plastic cement frame 2 that around the floor, is provided with, the guide pass 3 of inside contraction is set in the bottom in plastic cement frame 2 outsides, the locking raised line 4 of interruption distribution and the plastic cement slide block 5 that guide pass 3 is stretched out in the outer end are set on guide pass 3, plastic cement slide block 5 is positioned at the middle part of locking raised line 4, the direction recess 6 that the top setting of plastic cement slide block 5 matches with locking raised line on the corresponding assembled floor.The outside of the direction recess 6 of plastic cement slide block 5 has that the locking raised line supplied with on the corresponding assembled floor slips into smoothly slips into angle 7, and slipping into the angle is 20 °.Be provided with two reinforcing ribs 8 in 5 bottoms of plastic cement slide block.
When carrying out the floor assembly unit, lay first floor earlier, when laying second floor, earlier second floor is laterally moved, described plastic cement slide block 6 on second floor is slipped into the discontinuities of the described locking raised line 4 on described first floor, described locking raised line 4 on described first floor slides again, make described locking raised line 4 on described first floor slide into direction recess 6 above the described plastic cement slide block 5 on second floor, till the described plastic cement slide block 5 on second floor and the described plastic cement slide block 5 on first floor are run into mutually.By that analogy, row's floor assembly unit finishes, and also can follow the prescribed rules in the end on floor, and the floor of whole decorative cover all assembly unit finishes.
Above-described only is preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
Claims (3)
