Description
本发明涉及固定构件技术领域，具体为一种固定件。The invention relates to the technical field of fixing components, in particular to a fixing piece.
常见的固定构件有螺栓、螺钉、销轴或者铆钉等结构，而针对螺栓又衍生出诸如膨胀螺栓等种类。现有技术中，此类构件以标准件的形式被广泛应用在机械领域中。Common fixing members include structures such as bolts, screws, pins, or rivets, and types such as expansion bolts are derived for bolts. In the prior art, such components are widely used in the mechanical field in the form of standard parts.
作为标准件的应用中，以上固定件均有着自身所具备的优势以及应用场景，比如膨胀螺栓多用于墙体安装或者干挂结构上，铆钉多用于热加工工艺上，螺栓多用于可拆卸装配上，基于此类产品本身而言无疑是均是成功的设计。但是其产品本身又无法形成一个关联性高的产品模式，如采用螺栓那么只能实现固定，采用铆钉，难以拆卸。In the application of standard parts, the above fixing parts have their own advantages and application scenarios. For example, expansion bolts are mostly used for wall installation or dry-hanging structures, rivets are mostly used for thermal processing, and bolts are mostly used for detachable assembly. , Based on this type of product itself, it is undoubtedly a successful design. However, the product itself cannot form a highly relevant product model. If bolts are used, it can only be fixed, while rivets are difficult to disassemble.
所以申请人基于通用性、安装便利性以及稳定性上开发出一款新的固定件，从而形成一整套的产品模式，小如玩具、家具的装配，大如建筑钢结构的连接。并且其本身的连接并不需要适配的结构，只需要对应安装孔即可。不同于螺栓的连接需要螺纹，铆钉的连接需要冲压设备。Therefore, the applicant developed a new fixing piece based on versatility, installation convenience and stability, thus forming a complete set of product models, such as the assembly of toys and furniture, and the connection of building steel structures. And the connection itself does not require an adapted structure, only the corresponding mounting holes are required. Unlike bolted connections that require threads, rivet connections require stamping equipment.

为了便于使用，本发明实施例提供了一种固定件。下面将结合本发明实例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。For ease of use, an embodiment of the present invention provides a fixing piece. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the examples of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本实施例提供了一种固定件，首先参照图7，本实施例最初步应用的场景如图中所示的两个带孔部件进行过孔连接，带孔部件可以是连杆件或者板块。This embodiment provides a fixing member. Referring first to FIG. 7 , the initial application scenario of this embodiment is as shown in the figure, where two parts with holes are connected through holes, and the parts with holes can be connecting rods or plates.
固定件本身，设置至少两个膨胀块，此处“膨胀块”数量可根据实际情况中连接部位的大小布局进行设定；而至少为“两个”，并不是对其的具体限定，旨在说明膨胀块并非是一体式结构，属于分体结构。The fixture itself is provided with at least two expansion blocks, where the number of "expansion blocks" can be set according to the size and layout of the connection parts in the actual situation; and at least "two" is not a specific limit to it, it is intended to It shows that the expansion block is not a one-piece structure, but a split structure.
接着参照图1以及图2，此处仅以“两个膨胀块”的最简约单元进行详细说明。两个膨胀块分别是第一膨胀块2以及第二膨胀块3；定好膨胀块的数量之后，需要对膨胀块的轮廓结构进行设计，此结构设计时基于安装孔的结构，以图7的圆孔为例，膨胀块在使用时，需要周面抵接在孔壁上，所以为了手里均匀，提高固定效果，将膨胀块的周面设计成与圆孔孔壁轮廓曲率相近或者相等的弧形结构。若是方形孔也是同理，膨胀块用于抵接孔壁的周面与孔壁适配即可。Next, referring to Fig. 1 and Fig. 2, only the simplest unit of "two expansion blocks" will be described in detail here. The two expansion blocks are the first expansion block 2 and the second expansion block 3 respectively; after the number of expansion blocks is determined, it is necessary to design the outline structure of the expansion block, which is based on the structure of the installation hole. Take the hole as an example. When the expansion block is used, the peripheral surface needs to be in contact with the hole wall. Therefore, in order to make the hand uniform and improve the fixing effect, the peripheral surface of the expansion block is designed to be an arc that is similar to or equal to the curvature of the hole wall contour. shaped structure. The same is true for square holes, and the peripheral surface of the expansion block used to abut against the hole wall can be adapted to the hole wall.
最后是嵌入块1，嵌入块1是容置于膨胀块之间的部件，所以嵌入块1的结构设计应当基于膨胀块的数量以及分布而定的。The last is the embedded block 1, which is a component accommodated between the expansion blocks, so the structural design of the embedded block 1 should be based on the number and distribution of the expansion blocks.
参照图3以及图4，膨胀块为左右对称的两个时，两个膨胀块相对面之间嵌入块1只需具有两个侧面与膨胀块相对即可；膨胀块若是两个以上，呈中心对称分布，则嵌入块1在每个膨胀块相对面之间均设置侧面与之对应(其原理以及作用在本实施例后续中一一叙述)。参照图3的情况，四个膨胀块 对应的是截面为十字形的嵌入块1。Referring to Figure 3 and Figure 4, when there are two symmetrical expansion blocks, the embedded block 1 between the opposite faces of the two expansion blocks only needs to have two sides opposite to the expansion block; if there are more than two expansion blocks, the center Symmetrically distributed, the embedding block 1 is provided with a corresponding side between the opposite faces of each expansion block (its principle and function will be described one by one in the follow-up of this embodiment). With reference to the situation of Fig. 3, the four expansion blocks correspond to cross-section embedded blocks 1.
膨胀块在安装状态下具有相互排斥的力，从而使其能够预固定在图7所示的孔中，最后再***嵌入块1进行功能性安装。The expansion block has mutually repulsive forces in the installed state, so that it can be pre-fixed in the hole shown in Figure 7, and finally inserted into the insert block 1 for functional installation.
此处所称的“功能性安装”是指被连接的两个部件相对此固定件所要实现的功能，其中包括固定以及滑动。The "functional installation" referred to here refers to the functions to be realized by the two connected parts relative to the fixing member, including fixing and sliding.
在本发明的一个优选实施例中，采用磁性部件实现相斥力，即在膨胀块的想对面上设置两块磁铁从而实现相互排斥。In a preferred embodiment of the present invention, magnetic components are used to achieve repulsion, that is, two magnets are arranged on opposite sides of the expansion block to achieve mutual repulsion.
以图1和图2为例，具体的结构为：将第二膨胀块3以及第一膨胀块2设计成圆弧形外侧面结构，内侧面设置成平面结构，同时将嵌入块1设计成双平面侧壁的结构(具体参照图中所示)。为了方便生产以及装配，可将第二膨胀部3以及第一膨胀块2设置成相同的标准件结构。在该部分内嵌入磁性部，磁性部可采用永磁体或者电磁体(本实施例仅以永磁体为例)。同时在嵌入块1内同样嵌设磁性部(图中的14以及16)，第二膨胀块3/第一膨胀块2的磁性部与嵌入块1内的磁性部位置上相互对应，籍以形成如图2所示的状态，实现相邻部件之间的相吸或者相斥。另外设有的导向部参照图2所示，为导轨结构4，导轨结构4贯穿嵌入块1，连接第二膨胀块3和第一膨胀块2.在本实施例中，第二膨胀块3作为导轨的固定端，同时基于导轨的路径在嵌入块1上开设有避让孔15(同时作为导轨的引导槽)，同样的在第一膨胀块2上也开设了与导轨滑动连接的引导槽。值得一提的是，导轨的路径在两个磁性部的中间，可从图中嵌入块1的结构中明确看出(15位于167和14中间的位置)，而且导轨的延伸方向与磁性的相斥/相吸方向平行。Taking Fig. 1 and Fig. 2 as an example, the specific structure is as follows: the second expansion block 3 and the first expansion block 2 are designed as a circular arc-shaped outer side structure, the inner side is set as a planar structure, and the embedded block 1 is designed as a double The structure of the plane side wall (specifically refer to the figure shown). In order to facilitate production and assembly, the second expansion part 3 and the first expansion block 2 can be provided with the same standard structure. A magnetic part is embedded in this part, and the magnetic part can be a permanent magnet or an electromagnet (this embodiment only takes a permanent magnet as an example). Simultaneously, magnetic parts (14 and 16 among the figures) are also embedded in the embedding block 1, and the magnetic parts of the second expansion block 3/first expansion block 2 correspond to each other on the position of the magnetic parts in the embedding block 1, thereby forming In the state shown in Figure 2, mutual attraction or mutual repulsion between adjacent components is realized. In addition, as shown in Fig. 2, the guide part provided is a guide rail structure 4. The guide rail structure 4 runs through the embedded block 1 and connects the second expansion block 3 and the first expansion block 2. In this embodiment, the second expansion block 3 serves as At the fixed end of the guide rail, an avoidance hole 15 (simultaneously as a guide groove of the guide rail) is provided on the embedded block 1 based on the path of the guide rail, and a guide groove slidably connected with the guide rail is also provided on the first expansion block 2 similarly. It is worth mentioning that the path of the guide rail is in the middle of the two magnetic parts, which can be clearly seen from the structure of the embedded block 1 in the figure (15 is located in the middle of 167 and 14), and the extending direction of the guide rail is in line with the magnetism. The repulsion/attraction directions are parallel.
值得一提的是，膨胀块之间的相斥可以采用弹簧或者弹片等接触式安装的部件实现，具体参照图9和图10。图中的A是弹簧，B是弹片。It is worth mentioning that the mutual repulsion between the expansion blocks can be realized by contact-installed components such as springs or shrapnel, specifically refer to FIG. 9 and FIG. 10 . A in the figure is a spring, and B is a shrapnel.
此处值得一提的是，上述中所称的膨胀块优选为相同的配件结构，参照图3，即每个膨胀块的形状结构是相同的，相当于一个整体(相对于一个自身 结构对称的孔而言)，等分出几块作为膨胀块，此方案为本发明的优选方案。但是理论上也可以是不等分的，即每个膨胀块的是不相等的。如图4所示的情况，其中的1a区域既可以视作是膨胀块也可以作为嵌入块的部分。换而言之，嵌入块经过分体设计之后也可以实现膨胀块的功能，但是其分体设计相对于相邻的膨胀块之间也可以实现嵌入块自身的功能。具体到图4，1a区域与中心区域是相斥的用于抵接在孔壁上，但是1a区域与膨胀块之间可以是相斥的也可以是相吸的。It is worth mentioning here that the expansion blocks mentioned above are preferably the same accessory structure, referring to Figure 3, that is, the shape and structure of each expansion block are the same, which is equivalent to a whole (with respect to a symmetrical structure of its own. Hole), several pieces are equally divided as expansion blocks, this scheme is the preferred scheme of the present invention. But in theory, it can also be unequal, that is, each expansion block is not equal. As shown in Figure 4, the area 1a can be regarded as either an expansion block or a part of an embedded block. In other words, the embedded block can also realize the function of the expansion block after the split design, but the split design can also realize the function of the embedded block itself with respect to the adjacent expansion blocks. Referring specifically to Fig. 4, the area 1a and the central area repel each other to abut against the wall of the hole, but the area 1a and the expansion block may repel or attract each other.
另外，在第一膨胀块2以及第二膨胀块3的***周侧与连接孔对接的位置(如果嵌入块自身为分体结构用于抵接连接孔其***也应当设置该结构)，设置有抵接结构用于防脱(参照图中的X)，图1中采用的是开槽的方式籍以适配连接孔的内壁，连接时，将两个不见的连接孔内壁置于槽内，籍以实现防脱与稳定。在本发明的另外一些优选实施例中还可以通过设置外凸的凸点结构或者嵌设胶圈结构，其目的是为了增大此处摩擦，防止脱落。In addition, at the position where the outer periphery of the first expansion block 2 and the second expansion block 3 abuts with the connection hole (if the embedded block itself is a split structure for abutting against the connection hole, its periphery should also be provided with this structure), a The abutment structure is used to prevent falling off (refer to X in the figure). In Figure 1, the slotting method is used to fit the inner wall of the connection hole. When connecting, place the two invisible inner walls of the connection hole in the groove. In order to realize anti-off and stability. In some other preferred embodiments of the present invention, a protruding bump structure or an embedded rubber ring structure can also be provided to increase the friction here and prevent falling off.
关于“功能性安装”的设计，主要分为两种功能，一是固定功能，二是滑动功能。Regarding the design of "functional installation", it is mainly divided into two functions, one is fixed function and the other is sliding function.
包含了以下设计：嵌入块1采用过盈的方式容置在膨胀块内，进一步将膨胀块抵紧在孔壁上。The following design is included: the embedding block 1 is accommodated in the expansion block in an interference manner, and the expansion block is further pressed against the hole wall.
嵌入块1与膨胀块均为相吸结构，以此处的磁性部为例，嵌入块1与膨胀块相对的面上设置成磁性部相吸(可以是采用钢铁材料，也可以是另外安装磁铁与膨胀块的磁铁相吸)。此处值得一提的是，相吸的方案中，两个膨胀部依旧是抵住孔壁的，且至少是限位孔壁在轴向上的位移，防止脱落。此方案的优点在于，其固定效果明显，但是也具备一定的滑动效果，可将嵌入块1视为一个较长的滑轨，膨胀块带着被安装部件可以在该滑轨的任意位置实现滑动停留。The embedding block 1 and the expansion block both have a mutual attraction structure. Taking the magnetic part here as an example, the surface opposite to the embedding block 1 and the expansion block is set so that the magnetic part attracts each other (it can be made of steel, or a magnet can be installed separately. Attract the magnet of the expansion block). It is worth mentioning here that in the solution of mutual suction, the two expansion parts are still against the hole wall, and at least limit the displacement of the hole wall in the axial direction to prevent falling off. The advantage of this solution is that its fixing effect is obvious, but it also has a certain sliding effect. The embedded block 1 can be regarded as a longer slide rail, and the expansion block can slide at any position on the slide rail with the installed parts stay.
嵌入块1与部分的膨胀块相吸与另一部分的膨胀块相斥，以图1所示的 情况为例，嵌入块1与第一膨胀块2相吸，与第二膨胀块3相斥，那么基于上述中全部相吸的方案，该方案同样是可实现相对明显的固定效果，但是也具备滑动的能力，并且相对于上述，该方案滑动的摩擦力较小。The embedded block 1 attracts part of the expansion block and repels the other part of the expansion block. Taking the situation shown in Figure 1 as an example, the embedded block 1 attracts the first expansion block 2 and repels the second expansion block 3. Then, based on the above-mentioned schemes that all attract each other, this scheme can also achieve a relatively obvious fixing effect, but it also has the ability to slide, and compared with the above-mentioned scheme, the sliding friction of this scheme is smaller.
嵌入块1与所有的膨胀块都相斥，形成类似与磁悬浮的滑动结构。The embedded block 1 repels all the expansion blocks, forming a sliding structure similar to magnetic levitation.
综上，使用者可以采用如上的方案实现特定应用场景的作用。值得一提的是，本发明中的嵌入块1的轴向长度不需要限定的，也就是说，在嵌入块1上可同时允许上述的方案共存。例如在一段嵌入块上，可设置全相吸段，全相斥段或者半相吸半相斥段。To sum up, users can use the above solution to realize the function of specific application scenarios. It is worth mentioning that the axial length of the embedded block 1 in the present invention does not need to be limited, that is to say, the above solutions can coexist on the embedded block 1 at the same time. For example, on a section of embedded block, a full-attraction section, a full-repulsion section or a half-attraction and half-repulsion section can be set.
此处值得一提的是，分体的嵌入块(参照图4以及图5)，相互之间形成倾斜方向的斥力(图5中的箭头为力的方向)，由于分体嵌入块位于膨胀块之间，所以该倾斜的斥力形成两个分力，其中一个分力将分体嵌入块1a抵紧在孔壁上，另一个分力使得分体嵌入块1a挤压倾斜方向的膨胀块。从提高固定件与孔壁的适配成都。此处嵌入块之间的斥力同样可以采用磁性部件。弹簧或者弹片来实现。It is worth mentioning here that the split embedding blocks (refer to Figure 4 and Figure 5) form a repulsive force in an oblique direction (the arrow in Figure 5 is the direction of force), because the split embedding block is located on the expansion block Therefore, the inclined repulsive force forms two component forces, one of which presses the split embedding block 1a against the hole wall, and the other force makes the split embedding block 1a press the expansion block in the inclined direction. From improving the fit between the fixing part and the hole wall. Magnetic components can also be used for the repulsion between the embedded blocks here. Spring or shrapnel to achieve.
关于安装，基于上述固定件的结构设计，整个安装过程对于固定件本身来说实际上是两个形变过程，从压缩到膨胀。Regarding the installation, based on the structural design of the above-mentioned fixture, the entire installation process is actually two deformation processes for the fixture itself, from compression to expansion.
以图8的安装场景为例，以图7的安装场景为例，该图上的安装位置完全显露于外部。可以直接手持固定件压缩，再置入安装孔中释放得以膨胀固定。为了方便操作，可以在固定件上设置几个用于夹持的着力点。其中一个着力点必然放在膨胀部2上，另一个着力点放在定位部3或者基准部1上。安装前控制两个着力点相互靠近从而实现压缩状态，进入安装位置后释放，从而膨胀。Taking the installation scene in Figure 8 as an example, and the installation scene in Figure 7 as an example, the installation position in the figure is completely exposed to the outside. You can directly hold the fixing piece to compress it, and then put it into the installation hole to release it to expand and fix it. In order to facilitate operation, several force points for clamping can be set on the fixing piece. One of the focus points must be placed on the expansion part 2 , and the other focus point is placed on the positioning part 3 or the reference part 1 . Before installation, control the two points of force to approach each other to achieve a compressed state, and release it after entering the installation position to expand.
“着力点”如何设置：本实施例中采用的是开孔的方式，而类似于图8的安装场景，可以直接手指捏住孔的位置进行压缩或者释放。除了采用开孔的方式之外，从其本体端部上延伸出一个台阶得以实现着力的功能也是一样 的。How to set the "focus point": In this embodiment, the method of opening holes is adopted, and similar to the installation scene in Figure 8, you can directly pinch the position of the hole with your fingers to compress or release. In addition to adopting the method of opening, the function of extending a step from the end of the body to realize the force is also the same.
再参照图9，在图9的安装场景内，需要安装的部位在内部(图中的G处)，无法采用上述中直接手工的操作完成安装，但是安装的构思还是相同的，只需要将固定件完成压缩-膨胀的过程即可。Referring to Figure 9 again, in the installation scene shown in Figure 9, the part to be installed is inside (at G in the figure), and the above-mentioned direct manual operation cannot be used to complete the installation, but the concept of installation is still the same, only need to fix the The piece completes the compression-expansion process.
手工不能操作可以采用辅助器。该辅助器需要实现向前伸出的功能，所以其本体需要一个刚性的杆状物结构，同时杆状物与固定件的连接必须是可拆卸连接，其目的是为了在完成安装后将辅助器取回。另外，该可拆卸连接的操作端必然是位于手持端。以图2以及图5-6为例，在固定件上开设有若干螺纹孔(图中的21、11、31)，也可以同时开设无螺纹的孔(图中的12和13)用于临时的定位(如安装完毕之后的微调，可直接***定位杆进行)，或者用于过盈的定位，杆状物采用螺纹连接的方式与之实现“可拆卸”。具体的，至少需要两根螺纹杆，其一与膨胀部连接，另外一个与定位部2或者基准部1连接(也可以是三根杆，分别于这三块连接)，在连接后，捏紧杆状物的前端，使得膨胀部2压缩，而后送入安装位置，松开刚状物，使得膨胀部2完成膨胀。接着旋转杆状物将其取出。在此基础上，为了更加方便操作，在中部的基准部1的螺纹孔两侧还可设计两个孔，再用于***两根杆，使得压缩时膨胀部2与基准部1形成三角挤压结构，受力更加稳定，也就是图5以及图6所述的状态。再次回到安装结构上，通过本实施例的描述。其必要实现，应该具备如下条件：可前伸出的杆状物，杆状物与固定件的可拆卸连接。所以，基于该构思，本领域技术人员其他可想象的实现方案均在本发明的保护范围之内，包括但不限于：可拆卸连接采用孔的过盈，采用可解锁的卡扣结构，采用机械爪的夹持结构等等。Auxiliaries can be used for manual operation. The auxiliary device needs to achieve the function of protruding forward, so its body needs a rigid rod structure, and the connection between the rod and the fixing part must be detachable, the purpose of which is to remove the auxiliary device after installation retrieve. In addition, the operating end of the detachable connection must be located at the hand-held end. Taking Figure 2 and Figure 5-6 as an example, several threaded holes (21, 11, 31 in the figure) are opened on the fixing piece, and unthreaded holes (12 and 13 in the figure) can also be provided at the same time for temporary Positioning (such as fine-tuning after installation, can be directly inserted into the positioning rod), or for positioning of interference, the rod is connected with it by thread to achieve "detachable". Specifically, at least two threaded rods are required, one of which is connected to the expansion part, and the other is connected to the positioning part 2 or the reference part 1 (it can also be three rods, respectively connected to these three pieces), after the connection, pinch the rod The front end of the bar makes the expansion part 2 compress, and then it is sent to the installation position, and the rigid part is released, so that the expansion part 2 completes the expansion. Then rotate the rod to remove it. On this basis, in order to be more convenient to operate, two holes can be designed on both sides of the threaded hole of the reference part 1 in the middle, and then used to insert two rods, so that the expansion part 2 and the reference part 1 form a triangular extrusion during compression structure, the force is more stable, which is the state described in Figure 5 and Figure 6. Back to the installation structure again, through the description of this embodiment. Its necessary realization should meet the following conditions: a rod-shaped object that can be extended forward, and a detachable connection between the rod-shaped object and the fixing piece. Therefore, based on this idea, other conceivable implementations by those skilled in the art are within the scope of protection of the present invention, including but not limited to: the detachable connection adopts the interference of the hole, adopts the unlockable buckle structure, adopts the mechanical The clamping structure of the claw and so on.
此处值得一提的是，如上所述的采用孔(包括螺纹孔或者过盈孔的结构)作为“可拆卸结构”的着力方案，可选择单侧开孔的方式，使得固定件的安装结构只能从单侧进行卸下。应用在一些特殊场景中还具有防盗，防拆的效 果。It is worth mentioning here that, as mentioned above, using holes (including the structure of threaded holes or interference holes) as the "detachable structure" focus scheme, you can choose the way of opening holes on one side, so that the installation structure of the fixing parts Removal is only possible from one side. It also has the effect of anti-theft and anti-demolition in some special scenarios.
基于以上辅助器，为了节约成本，在膨胀块相斥的实现中可以依靠辅助器实现。在本发明的另一个优选实施例中，在辅助器的杆状物靠近固定件的一段安装可实现膨胀块排斥的部件，如磁性部件、弹簧或者弹片等等。此处提出一种采用磁性部件的结构：在杆状物上设置电磁铁结构，通过电流方向来单独控制每个杆状物上电磁铁的磁性，从而实现相邻刚状物相吸或者相斥，那么与刚状物连接的膨胀块或者分体的嵌入块也实现了相吸或者相斥。从而实现上述的安装以及稳定。Based on the above auxiliary devices, in order to save costs, the mutual repulsion of the expansion blocks can be realized by means of auxiliary devices. In another preferred embodiment of the present invention, components that can realize the repelling of the expansion block, such as magnetic components, springs or shrapnel, etc., are installed on a section of the rod of the auxiliary device that is close to the fixing member. A structure using magnetic components is proposed here: an electromagnet structure is set on the rods, and the magnetism of the electromagnets on each rod is individually controlled through the direction of the current, so that adjacent rigid objects attract or repel each other , then the expansion block or the split embedded block connected with the rigid object also realizes mutual attraction or mutual repulsion. Thereby, the above-mentioned installation and stabilization are realized.
