地板锁扣技术领域本实用新型涉及一种板类之间的联结结构，特别是指一种地板锁扣。 Floor lock Technical Field The present invention relates to a coupling structure between the plate type, and particularly to a floor lock. 背景技术现有的通过榫头水平卡入卡槽的方式进行内固定的地板，在拼装到边缘时安装困难，即使勉强安装完成，以后维修时也难以取出。 BACKGROUND ART Conventional horizontal Ka Ruka tenon groove by way fixed floors, installation difficulties when assembled to the edge, even if we manage to complete the installation, maintenance and repair when it is difficult to remove. 专利03259766. 5 公开了一种连环锁扣地板，它提了一种解决方式，由地板板体上部侧向延伸构成向下凸起的榫头及相邻的卡沟，在与其平行的另一个侧面方向，由地板板体下部侧向延伸构成向上凸起的榫头及相邻的卡沟， 一侧的榫头和卡沟分别与相邻地板的另一侧的卡沟和榫头配合，构成连环结构。 Patent No. 03259766.5 discloses a floor chain latch, provide a solution which, extending from the upper lateral floor plate body downwardly projecting tenon and groove adjacent to the card, the other side surface parallel thereto directions, by the lower lateral floor plate extending upwardly convex configuration of tenon and groove adjacent to the card, and the card side of the tenon and groove are adjacent to the other side of the floor of the groove and tenon mating card, constituting a chain structure. 但是，在不太平整的地面使用现有的地板锁扣时，不管是水平或者角度卡接还是上下竖直卡接，由于榫头无法形变，表面会由于挤压出现翻边，或者在表面出现缝隙，影响地板美观及寿命。 However, when using existing floor lock in the not too flat on the ground, either horizontally or vertically up and down angle or snap-snap, because the tenon can not deformation, the surface will be, or appear on the surface due to the squeeze gap appears flanging , floor and beautiful life. 同时在不够平整的地面上地板表面在受到外力时会产生震动，由于榫头无法相应的做出形变，地板锁扣在震动中容易松脱。 At the same time not enough on flat ground floor surface when subjected to external forces will vibrate, due to the tenon can not make a corresponding deformation, easy to loose floor lock in the shock. 发明内容为了克服上述的不足，提供一种地板锁扣，使得结合后地板的板体表面接缝紧密，板体之间结合牢固，当板体受外力发生震动时锁扣也不易松脱。 SUMMARY OF THE INVENTION To overcome the above shortcomings, there is provided a floor lock, so that upon binding the surface of the floor board tight joints, strong binding between the plate member, the plate member when the external force is less likely to vibrate loose latch. 本实用新型采用的技术方案是： 一种地板锁扣，在板体的一边设置榫头， 另一边上开有卡槽，卡槽与榫头互相匹配，在榫头上开有容许榫头发生弹性形变的槽，在榫头和卡槽结合处设置有可使榫头和卡槽相互锁定的锁紧机构。 The present invention uses the technical solution is: A floor lock, tenon disposed on one side of the plate, the other side is opened slot, slot and tenon match each other, the tenon is opened allowing elastic deformation of the grooves on the tenons , the slot and the tenon can bind with a locking mechanism is provided at the tenon and the slot interlocked. 在一般的长条形强化地板上，在长度方向上设置这样的一对榫头和卡槽， 在宽度方向上同样设置这样一对榫头和卡槽。 In a general elongated reinforcing the floor is provided a pair of such slots and tenon in the longitudinal direction, and also arranged so that one pair of tenons and slots in the width direction. 榫头和卡槽方向相对于地板的板体平面分为水平设置和竖直设置。 Tenon and the slot direction relative to the floor plate and the vertical plane is divided into horizontally disposed. 设计竖直方向设置榫头和卡槽是因为当地板拼装到边缘时，水平卡入的地板锁扣安装困难，所以设计一种板体上的榫头和卡槽竖直方向卡入咬合。 Design of the vertical direction because the tenon and slot are local to the edge plate when assembled, the floor snap lock mounting difficulty levels, so the design of the tenon and the slot in the vertical direction on a card plate into engagement. 为了减少加工面积，同时防止安装工人的误安装，榫头的一个榫面小于另一个榫面，与榫头配合的卡槽的相应缘短于另一个缘。 To reduce the processing area, while preventing erroneous mounting installers, a tenon is smaller than the other surface of the tongue surface tenon, and assembled with the corresponding edge of the slot is shorter than the other edge. 榫头和卡槽上的锁紧机构为在榫头的至少一个榫面上设置的至少一个锁定凸起或凹进和在卡槽的相对应处设置的与该锁定凸起或凹进相匹配的凹进或凸起。 A locking mechanism on the tenon and slot provided in at least one tongue surface at least one locking tenon projections or recesses and arranged in the slot at a position corresponding to the locking convex or concave recess matches or into the projection. 为了进一步完善这种联结结构，在板体的侧边由表面向下、向内倒一斜角，使拼接后相邻的板体间的表面接缝下形成一条倒v型槽。 In order to further improve this coupling structure, the side plate downwardly inwardly from the surface at an oblique angle down, the surface of the seam between adjacent splice rear plate formed at an inverted v-groove. 在联接过程中可以在倒v型槽中使用胶粘剂或防水胶，进一步提高联结力和防水功能，倒V型槽的顶角P为3〜5度。 During coupling may be used in an inverted v-groove waterproof glue or adhesive, to further enhance the coupling force and water resistance, inverted V-shaped groove vertex angle P is 3 to 5 degrees. 并且为了使板体在安装和热胀冷縮时留有余地，也为了使表面安装后接缝紧密，在板体的侧边由底面向内开一槽口，使拼接后相邻板体间的底部形成一条工艺槽。 And in order to leave room for the plate during installation and thermal expansion and contraction, and to close the seam after installation of the surface, a notch opening facing the side of the bottom plate, so that after the splicing between adjacent plates the process of forming a groove bottom. 本实用新型的有益效果是：在榫头卡入卡槽时，榫头受卡槽两侧挤压， 使榫头依靠槽发生可还原性形变，在到达锁紧机构的咬合点后榫头还原，达到锁紧目的，由于榫头内的槽，安装面的髙低对表面产生的挤压力或缝隙都能在榫头的槽中抵消，从而达到表面平整、紧密。 The beneficial effects of the present invention is: when the tenon groove Ka Ruka, by tenons on both sides of the extrusion slot, relying on that the tenon groove can occur reducing deformation tenon reduction after reaching the nip point of the locking mechanism, to lock object, because the tenon groove, or slot Gao low pressing force is generated on the surface of the mounting face can be offset in the groove of the peg, so as to achieve smooth surface, closely. 更重要的是在咬合后，锁扣不易受外力影响而发生松脱，尤其是表面受冲击靂动时效果更为明显。 More importantly, in the nip, the latch loosened easily affected by external force occurs, particularly when the impact receiving surface of the movable clap effect more visible. 附图说明下面结合附图和实施例对本实用新型进一步说明。 BRIEF DESCRIPTION The present invention is further described in conjunction with the accompanying drawings and embodiments pair.
