Description

TECHNICAL FIELD

[0001] The present application relates to the field of connectors, in particular to a multifunctional engineering connector and an engineering system thereof. BACKGROUND

[0002] As a core basic component in the field of building structure, equipment assembly, etc., the engineering connector needs to consider the stability and fixation of the connection part and the practical function in different scenarios, and the pressing block accessory, installation process and structural design of the connector directly determine the installation efficiency, operation and maintenance cost and service life of the whole project. In the actual application of the current engineering connector, there are still the following outstanding problems around the pressing block accessory, installation process and function adaptability.

[0003] The existing engineering connector is exposed to outdoor or humid environment for a long time (such as building outer wall connection, outdoor equipment fixation), and needs to frequently deal with liquid erosion such as rain and dew. However, the existing pressing block accessory is not specially designed for sealing and drainage requirements: the fitting surface of the pressing block, the water guide groove and the connecting branch plate lacks special sealing structure and flow guide channel, and liquid is easy to penetrate into the gap between the pressing block and the water guide groove, forming local water accumulation; long-term retention of water accumulation can accelerate the corrosion of the metal parts of the connector, leading to a decrease in connection strength and an increase in the frequency and cost of later maintenance.

[0004] The existing engineering connector does not design a reinforcing structure according to the stress characteristics of different scenarios (such as vibration caused by equipment operation, outdoor wind load, bearing pressure of building structure): part of the main body of the connector is not provided with reinforcing ribs, which leads to weak stress in the middle part, and when the connecting branch plate is subjected to the self-weight or external force for a long time, deformation such as middle part depression and edge warping is easy to occur; even during the installation stage, the structure is not strong enough to cause deformation when tightening the fasteners (such as bolts), at which time a new connector needs to be replaced or corrected by pulling, hammering, etc., which not only reduces the structural strength of the connector itself, but also significantly prolongs the installation time and affects the overall project progress.

[0005] The installation of the existing engineering connector needs to follow the fixing sequence of "water guide groove → connecting branch plate → pressing block accessory → fastener", but the design defects of the key components lead to complicated processing and installation process: the nut of the connector is often fixed on the bracket by welding process, and each bracket needs to be welded with a nut separately, which is redundant and easy to cause deformation of the bracket due to welding temperature and precision error; at the same time, the nut lacks positioning and limiting structure after pressing, which is easy to deviate in subsequent operation, and when the bolt is installed, the coaxiality of the bolt and the nut needs to be adjusted repeatedly, even if the electric tool is used to tighten, the tool is often idle or the bolt is loose due to misalignment, which significantly prolongs the installation time of a single set of connector and reduces the overall construction efficiency.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in connection with the specific embodiments.

[0038] In one embodiment, please refer to the drawings attached Figures 1-4As shown in 9-10, the multifunctional engineering connector of the application comprises a plurality of connecting plates 1, a first connector 2 and a second connector 3 for supporting the connecting plates 1, a buckle cover plate 4 is arranged at the connecting position of the connecting plates 1, and the buckle cover plate 4 is used for sealing the gap between the connecting plates 1; a support assembly 6 is arranged above the second connector 3, the support assembly 6 is used for connecting the second connector 3, a middle pressing cover plate 5 is arranged above the support assembly 6, the middle pressing cover plate 5 is used for pressing the connecting plates 1, a bolt 7 is arranged on the middle pressing cover plate 5, a nut 8 is installed on the support assembly 6, and the bolt 7 and the nut 8 are connected through threads; and the buckle cover plate 4 is covered above the middle pressing cover plate 5.

[0039] The multifunctional connector is a new connector device integrating efficient support, sealing protection and convenient installation, and its core structure is developed around the stable fixation and efficient operation of the connecting plates, mainly comprising a plurality of connecting plates 1, a first connector 2, a second connector 3, a buckle cover plate 4, a middle pressing cover plate 5, a support assembly 6, a bolt 7, a nut 8 and a purlin 10, and each component cooperates to ensure the stable operation and efficient power generation of the connector. The first connector 2 and the second connector 3 are water guide grooves for draining water. The connecting plates 1 are connected by a plurality of plates, and edge pressing square tubes 101 are arranged at both ends of the connecting plates 1, which are connected with a shed or a wall. The connecting plates 1 are prior art, and will not be described here.

[0040] Please refer to the drawings in the specification Figures 1-8 As shown in the drawings, the connecting plates 1 serve as the core power generation components, and their arrangement and connection stability directly affect the overall power generation efficiency. To achieve reliable support of the connecting plates 1, the support assembly 6 is arranged above the first connector 2 and the second connector 3, which not only bears the weight of the connecting plates 1, but also quickly drains rainwater in rainy weather to avoid corrosion and damage to the connecting plates 1 and the support components. The second connector 3 has a unique cross-sectional structure, which has a larger water drainage capacity and a stronger structural strength than the traditional water guide groove, and can adapt to different rainfall intensities and wind loads in different regions.

[0041] A buckle cover plate 4 is specially arranged at the connecting position of the connecting plates 1 to prevent too much water from flowing into the interior of the second connector 3, thereby reducing the amount of water drained during the pressing of the connecting plates 1 and ensuring that the discharge capacity of the second connector 3 is sufficient to completely drain the water entering its interior. The buckle cover plate 4 seals the edges of the battery plates on the connecting plates 1, which significantly reduces the amount of water entering the interior of the second connector 3.

[0042] The cover plate 4 is made of aluminum alloy material, which is perfectly matched with the connecting gap of the connecting branch plate 1. It can effectively seal the gap between the connecting branch plates 1, prevent impurities such as rainwater and dust from entering the gap and eroding the module frame and terminal, and also has a certain buffering effect, which can reduce the mutual extrusion damage of the connecting branch plates 1 caused by thermal expansion and contraction or vibration under temperature change or external force, and improve the appearance neatness of the whole array of connecting branch plates 1.

[0043] Please refer to the drawings in the description Figure 3 、 5 As shown in the drawings, the middle cover plate 5 includes a pressing block 51, and a bolt hole is formed in the middle of the pressing block 51 for the bolt 7 to pass through; the two sides of the pressing block 51 are provided with a pressing plate 52, which is used to fit on the frame of the connecting branch plate 1, and the lower surface of the pressing plate 52 is provided with a plurality of friction strips 53; the pressing plate 52 is in U-shaped groove structure, and two inwardly protruding clamping strips 54 are arranged on the inner wall of the pressing plate 52, which are clamped with the clamping blocks on the cover plate 4, so that the cover plate 4 is fixed.

[0044] The middle cover plate 5 is a key component to realize the stable fixation of the connecting branch plate 1, and its structure design fully considers the fixation reliability, installation convenience and protection of the connecting branch plate 1, mainly composed of the pressing block 51, the pressing plate 52, the friction strip 53 and the clamping strip 54. Since the middle cover plate 5 is covered on the connecting branch plate 1, if there is no cooperation of the cover plate 4 and the middle cover plate 5, when the internal water of the second connecting piece 3 is too much, the water will overflow from the two sides of the second connecting piece 3. The pressing block 51, as the main structure of the middle cover plate 5, is integrally formed by high-strength aluminum alloy material, which has excellent bearing capacity and corrosion resistance. In the middle of the pressing block 51, a bolt hole matching the size of the bolt 7 is accurately formed, and the inner wall of the bolt hole is precisely processed to ensure the smoothness when the bolt 7 passes through, and to avoid the installation shaking caused by the too large gap between the bolt 7 and the hole wall.

[0045] The two sides of the pressing block 51 are symmetrically provided with the pressing plate 52, which is an integrated structure with the pressing block 51, and its length is matched with the width of the frame of the connecting branch plate 1, so that the pressing plate 52 can be completely fitted on the frame of the connecting branch plate 1. To further improve the fixation stability between the pressing plate 52 and the frame of the connecting branch plate 1, a plurality of friction strips 53 are uniformly arranged on the lower surface of the pressing plate 52. These friction strips 53 are long strip-shaped protrusions integrally formed with the pressing plate 52, and have anti-slip texture on the surface. When the pressing plate 52 presses the frame of the connecting branch plate 1, the friction strips 53 can be tightly fitted on the surface of the frame of the connecting branch plate 1, greatly increasing the friction between them, effectively preventing the displacement of the connecting branch plate 1 under the action of external forces such as wind and earthquake, and the elastic material can also avoid the hard extrusion damage of the frame of the connecting branch plate 1 caused by the pressing plate 52.

[0046] In addition, the pressing plate 52 is designed as a U-shaped groove structure, which not only reduces the overall weight of the pressing plate 52 and the load of the support assembly 6, but also facilitates the setting of functional structures on the inner wall of the U-shaped groove. Two inwardly protruding clamping strips 54 are symmetrically arranged on the inner wall of the U-shaped groove of the pressing plate 52. The clamping strips 54 are integrally formed with the pressing plate 52, and the protruding height thereof is accurately matched with the size of the clamping blocks on the cover plate 4. When the cover plate 4 is covered on the middle pressing plate 5, the clamping blocks on the cover plate 4 can be perfectly clamped with the clamping strips 54 on the inner wall of the pressing plate 52. Through the limiting action of the clamping strips 54 on the clamping blocks, the cover plate 4 is firmly fixed, preventing the cover plate 4 from falling off or shifting due to the influence of external environmental factors, and ensuring the long-term stability of the sealing effect.

[0047] Please refer to the drawings in the description Figure 3 and 5 As shown in FIG. 9, the support assembly 6 is provided with a through groove 61 and a blocking block 62 arranged on both sides of the through groove 61. The through groove 61 is used for installing a nut 8, and when the bolt 7 is tightened, the nut 8 is clamped on the inner wall of the through groove 61. The middle part of the support assembly 6 is provided with a positioning hole 67 for the bolt 7 to pass through. The two sides of the support assembly 6 are provided with clamping plates 63 which are clamped with the second connecting piece 3. The clamping plates 63 are provided with mounting holes 64, and screws connected to the second connecting piece 3 are mounted on the mounting holes 64.

[0048] The support assembly 6 further comprises guiding ribs 65 arranged on the inner wall of the through groove 61. The nut 8 slides along the guiding ribs 65 inside the through groove 61. The end of the guiding rib 65 is provided with an elastic sheet 66 which is in an arc structure. When the nut 8 slides to the arc surface of the elastic sheet 66 from the guiding rib 65, multiple elastic sheets 66 support the nut 8 together. The lower part of the elastic sheet 66 is provided with a supporting block 68, and the end of the supporting block 68 is connected to the inner wall of the support assembly 6. The inclined edge of the elastic sheet 66 is parallel to the side of the nut 8, and two sides of the nut 8 are parallel to the inner wall of the through groove 61. Multiple elastic sheets 66 are used to abut against the nut 8 to position it. The axis of the nut 8 is coaxial with the axis of the bolt 7, making it easy for the bolt 7 to be screwed into the interior of the nut 8.

[0049] The support assembly 6 is a core transition component connecting the second connecting piece 3 and the middle pressing plate 5. Its structural design is carried out around the convenient installation, accurate positioning and structural reinforcement, mainly including the through groove 61, the blocking block 62, the positioning hole 67, the clamping plate 63, the guiding rib 65, the elastic sheet 66 and the supporting block 68. Each structure cooperates with each other to realize the dual improvement of the installation efficiency and the structural stability of the support assembly 6.

[0050] In the middle of the support assembly 6, a through groove 61 for installing the nut 8 is opened, the cross-sectional size of the through groove 61 is matched with the shape of the nut 8, which ensures that the nut 8 can be smoothly put into the through groove 61, and when the bolt 7 is tightened, the nut 8 can be tightly clamped on the inner wall of the through groove 61, avoiding the nut 8 rotating with the bolt 7. The blocking block 62 is used to limit the position of the connecting support plate 1, and a positioning hole 67 is also provided in the middle of the support assembly 6, which is coaxially aligned with the bolt hole on the pressing block 51, and the hole diameter is slightly larger than the diameter of the bolt 7, which can not only ensure that the bolt 7 can pass through smoothly, but also can accurately position the bolt 7, avoiding the bolt 7 from deviating during installation, and ensuring that the bolt 7 can accurately butt joint with the nut 8 in the through groove 61.

[0051] Please refer to the drawings Figures 5-10 As shown in the drawings, the support assembly 6 is symmetrically provided with a clamping plate 63 on both sides, the clamping plate 63 is integrally formed with the support assembly 6, and the shape is matched with the notch structure of the second connecting piece 3, which can quickly realize the clamping connection with the second connecting piece 3, and preliminarily realize the positioning of the support assembly 6 on the second connecting piece 3. In order to further strengthen the connection stability of the support assembly 6 and the second connecting piece 3, an installation hole 64 is also opened on the clamping plate 63, the position of the installation hole 64 accurately corresponds to the pre-installed position on the second connecting piece 3, and the clamping plate 63 and the second connecting piece 3 are firmly connected by installing a screw in the installation hole 64, so as to realize the stable fixation of the support assembly 6 on the second connecting piece 3. Compared with the existing technology, the screw is fixed into the second connecting piece 3 from the top of the support assembly 6, the operation space is larger, the installer does not need to operate in the narrow side space, which greatly reduces the installation difficulty and improves the installation efficiency.

[0052] The cross-sectional opening of the second connecting piece 3 is designed as a drainage groove, and the M-shaped cross-section forms three guide channels. The support assembly 6 is provided with two water guide openings, which further improve the drainage effect of the support assembly 6. After the rainwater falls on the surface of the battery panel of the connecting support plate 1, it flows along the edge of the battery panel to the drainage groove, and then quickly flows to the end of the drainage groove through the design of the drainage groove, and there is no accumulation in the whole process. At the same time, the several water guide openings opened on the front of the support assembly 6 can quickly drain the rainwater falling on the surface of the support assembly 6 into the second connecting piece 3 below, avoiding the accumulation of rainwater on the support assembly 6. Moreover, the design of the water guide opening not only has the effect of drainage, but also realizes the lightweight design of the support assembly 6, reducing the overall weight of the support assembly 6.

[0053] The cooperation of the middle pressure cover plate 5, the nut 8, the bolt 7 and the support assembly 6 realizes the effect of pressing and fixing the connecting support plate 1, and the locking process is simpler. The middle pressure cover plate 5 plays a protective and waterproof effect on the nut 8 and the bolt 7.

[0054] The design sets the through slot 61, the guide rib 65 and the elastic sheet 66 on the support assembly 6, which not only avoids the structural defects caused by the welding process, but also enhances the overall structural strength of the support assembly 6 through the guide rib 65, effectively prevents the support assembly 6 from deforming during installation and use, ensures that the nut 8 is always in a precise positioning state, and guarantees the reliable butt joint of the bolt 7 and the nut 8.

[0055] The positioning hole 67 is opened on the support assembly 6, and the nut 8 is precisely positioned through the guide rib 65 and the elastic sheet 66, so that the axis of the nut 8 and the axis of the bolt 7 always remain coaxial. The installer only needs to insert the end of the bolt 7 into the corresponding positioning hole 67 inside to realize the precise butt joint of the bolt 7 and the nut 8, without the need to find the nut position additionally, which greatly simplifies the installation operation and improves the positioning accuracy.

[0056] To solve the problems of difficult nut positioning and easy rotation in the prior art, the guide rib 65 is arranged on the inner wall of the through slot 61 of the support assembly 6. The guide rib 65 is inclined, which facilitates the sliding of the nut 8. The guide rib 65 is integrally formed with the support assembly 6, and its height is adapted to the thickness of the nut 8. When the nut 8 is installed, the nut 8 can smoothly slide along the guide rib 65 inside the through slot 61. The guide rib 65 has two functions here. One is that the guide rib 65 not only provides a precise guide path for the nut 8, avoiding the nut 8 from deviating during installation, and the other is that the guide rib 65 greatly enhances the overall structural strength of the support assembly 6, plays the role of a reinforcing rib, and improves the bending resistance and deformation resistance of the support assembly 6, effectively solving the problem of easy deformation of the inverted U-shaped existing support 100 during installation.

[0057] At the end of the guide rib 65, an elastic sheet 66 is arranged, which is made of a metal material with high elasticity and wear resistance and has an arc structure. The inclined edge of the elastic sheet 66 is parallel to the edge of the nut 8. When the nut 8 slides along the guide rib 65 and passes through the elastic sheet 66, the elastic sheet 66 will be elastically deformed under the extrusion of the nut 8. After the nut 8 slides to the arc surface of the elastic sheet 66, the elastic sheet 66 has an upward elastic force. At this time, the plurality of elastic sheets 66 jointly abut and position the nut 8, so as to ensure that the axis of the nut 8 is coaxial with the axis of the bolt 7. It is easier to be contacted by the bottom of the bolt 7, so as to facilitate the bolt 7 to be screwed into the inside of the nut, so that the bolt 7 can be easily screwed into the inside of the nut 8. When the nut 8 is limited on the elastic sheet 66, the stroke of the upward movement of the bolt 7 is shortened, and the bolt 7 will not have a sluggish feeling during the upward movement after being positioned. A shorter bolt 7 can be used to complete the process of tightening the bolt 7. During the process of tightening the bolt 7, the nut 8 does not need to be slowly moved upward from the lowest end to above the through groove 61. At the same time, the inner wall of the through groove 61 can limit the rotation of the nut 8. Even if the elastic sheet 66 is extruded and deformed during the process of tightening the bolt 7, the two sides of the nut 8 will still abut on the inner wall of the through groove 61, so as to avoid the nut 8 from rotating with the bolt 7. It is not necessary for the installer to additionally position the nut 8 by fingers or tools, so as to completely solve the problem that the bolt 7 cannot be tightened due to the rotation of the nut 8, and significantly simplify the installation process. When the bolt 7 is tightened, the pressing block 51 and the support assembly 6 are close to each other, so as to further strengthen the fixation and limitation of the support assembly 6 and improve the stability of the overall structure.

[0058] The nut 8 is pushed into the accommodation groove formed by the surfaces of the four elastic sheets 66 from the side of the support assembly 6 along the guide rib 65. The accommodation groove effectively limits the nut 8, and the inner wall of the through groove 61 can limit the rotation of the nut 8. Even if the elastic sheet 66 is extruded and deformed during the process of tightening the bolt 7, the two sides of the nut 8 will still abut on the inner wall of the through groove 61, so as to ensure that the nut 8 will not rotate with the bolt 7. It is not necessary for the installer to additionally position the nut 8, so as to realize the smooth tightening of the bolt 7, significantly improve the installation efficiency and fixation effect.

[0059] Please refer to the accompanying drawings Figure 10 As shown in the drawings, the cover plate 4 has a π-shaped structure, and elastic pads are arranged at the ends of the cover plate 4 extending outward on both sides. When the cover plate 4 is closed on the middle pressing plate 5, the elastic pads are extruded and sealed at the connection between the cover plate 4 and the middle pressing plate 5.

[0060] The two ends of the cover plate 4 extending outward are provided with elastic pads which can be made of rubber. During the process of closing the cover plate 4 downward, the elastic pads are extruded and deformed at the contact position with the middle pressing plate 5, and the connection between the cover plate 4 and the middle pressing plate 5 is in a sealed state.

[0061] Please refer to the accompanying drawings Figure 10As shown, the second connecting piece 3 is provided with a purlin 10 fixed on the bottom of the second connecting piece 3 by two groups of screws for supporting the second connecting piece 3.

[0062] The purlin 10 as the bottom supporting component of the second connecting piece 3 is made of high-strength steel material, and has excellent load-bearing capacity and bending resistance due to the optimized design of the cross-sectional structure. The purlin 10 is fixed on the bottom of the second connecting piece 3 by two groups of screws symmetrically distributed to ensure that the second connecting piece 3 is uniformly stressed on the purlin 10, avoiding deformation of the second connecting piece 3 or the purlin 10 due to stress concentration. The purlin 10 not only provides stable support for the second connecting piece 3 and uniformly transmits the weight of the second connecting piece 3 and the connecting support plate 1 above to the foundation structure, but also adjusts the installation height and levelness of the second connecting piece 3 to a certain extent, ensuring the installation precision of the entire array of connecting support plates 1 and providing reliable guarantee for the stability of the connecting support plate 1.

[0063] The landscape guide groove 9 can guide the climbing or arrangement of decorative light strips of vine plants according to the installation scene requirements, realizing the landscape decoration function of the connecting piece.

[0064] In another aspect, the present application also provides an engineering system comprising the multifunctional engineering connecting piece according to any one of the above.

[0065] Installation process: Compared with the existing bracket 100 side, the screw is more easily installed from the top of the bracket assembly 6 into the interior of the second connecting piece 3; the existing one is that the nut 8 is welded in the middle of the existing bracket 100 (see the attached drawings of the specification) Figure 11The existing support 100 is prone to deformation during installation (as shown in the figure); the positioning hole 67 is arranged on the support assembly 6, which facilitates positioning of the bolt 7, and during installation, the nut 8 is aligned with the positioning hole 67, thereby avoiding the need to position the nut 8 during installation, and only the end of the bolt 7 needs to be inserted into the corresponding positioning hole 67; the nut 8 is pushed into the storage groove from the side of the support assembly 6 along the position of the guide rib 65, and the storage groove is a nut 8 placement formed on the surface of the four elastic pieces 66, and the four surfaces of the nut 8 are attached to the corresponding elastic pieces 66; so that the nut 8 is limited in the storage groove. The guide rib 65 not only plays a guiding role for the nut 8, but also strengthens the strength of the support as a whole; it has the additional function of a reinforcing rib; the storage groove supports the nut 8 at the same time, so that the bolt 7 does not need to move the nut upward from the bottom of the through groove 61 after entering the nut 8, shortening the stroke of the bolt 7, avoiding the wear of the inner wall of the through groove 61 caused by the movement of the nut in the through groove 61 during installation, and also avoiding the need for additional fingers or tools to position the nut 8, preventing the nut 8 from rotating with the bolt 7 during tightening of the bolt 7, thereby making the installation process simpler. If this method is not used, when the nut 8 is located at the bottom of the through groove 61, the bolt 7 is aligned with the nut 8 when the bolt 7 is rotated, and due to the limitation of the through groove 61 on the nut 8, the nut 8 is limited to rotate by a certain angle, and the nut 8 cannot rotate, and when the bolt 7 continues to rotate, the corners of the nut 8 are pressed against the inner wall of the through groove 61, and due to the screwing action of the bolt 7 and the limiting action of the through groove 61, the nut 8 will continuously move upward during tightening of the bolt 7, and during tightening of the bolt 7, a clear feeling of hesitation will occur; the upward moving bolt 7 will also wear the inner wall of the through groove 61; when this method is used, after the nut 8 enters the through groove 61, the through groove 61 will limit the rotation of the nut 8, even during tightening of the bolt 7, the elastic pieces 66 are pressed and deformed, and the two ends of the elastic pieces 66 are not connected to the through groove 61, and bend downward when pressed by the nut 8; because the lower part of the elastic piece 66 is provided with a support block 68, the support block 68 can support the elastic piece 66 from serious deformation, prevent the nut 8 from pressing the elastic piece 66 too much and falling downward from between the elastic pieces 66; because the two sides of the nut 8 will abut against the inner wall of the through groove 61, the nut 8 will not rotate and move upward during tightening, and will not cause wear to the inner wall of the through groove 61, thereby enabling the bolt 7 to tighten the nut 8, and during tightening of the nut 8, the pressing block 51 and the support assembly 6 will move closer to each other, thereby achieving the effect of limiting the support assembly 6; when the nut 8 needs to be disassembled, a tool can be inserted through the through groove 61 to abut against the nut 8, pushing the nut 8 onto the guide rib 65, thereby facilitating removal of the nut 8, or a tool can be used to push the nut 8 to move onto the guide rib 65 and slide downward to be discharged from the inside of the through groove 61 according to actual needs.
