Description

Technical Field

[0001] The present invention relates to the technical field of architectural design, and particularly to a portable drawing outdoor display device for architectural design. Background Art

[0002] Before building a building, people usually design a construction drawing first to facilitate the construction implementation during construction. Therefore, the display of the drawing is very important. In the prior art, the patent publication number is CN210989178U, and a Chinese utility model patent discloses a building design drawing display rack for architectural design, including a base body. Universal wheels are provided at the four corners of the bottom of the base body. A slope is installed on the top of the base body. A first gear rotating shaft is installed at the center position near the bottom of the slope. The first gear rotating shaft is installed at one joint of the movable bracket. A second gear rotating shaft is installed at the other joint of the movable bracket. A third gear rotating shaft is installed at the midpoint of the second gear rotating shaft. By setting the movable gear joint bracket in the present invention, the height of the display rack can be freely and flexibly adjusted. At the same time, the combination between the slope and the bracket also takes into account the aesthetics of the design. The vertical gear rotating shaft on the back of the display panel enables the display panel to adjust the left and right display angles. In addition, since the vertical gear rotating shaft is fixed on the horizontal gear rotating shaft, the display panel can adjust the up and down angles.

[0003] However, the above display rack has a complex structure and is overall heavy. Many times during outdoor construction, when it is necessary to conduct surveys, confirm details, or involve on-site collaboration, dynamic adjustment, or designs with strong environmental relevance by referring to the drawings, outdoor carrying of drawing displays is essential. However, the existing architectural design display racks are not easy to carry, have a complex structure, a relatively large overall weight, and are inconvenient to disassemble and assemble. For example, on high slopes or mountaintops, they cannot be carried and used according to the usage environment at any time.

[0004] Therefore, how to improve the portability of architectural design drawing display devices is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to overcome the deficiencies in the prior art and provide a portable drawing outdoor display device for architectural design to improve the portability of architectural design drawing display devices.

[0006] To achieve the above-mentioned purpose, the present invention provides a portable outdoor display device for architectural design drawings, comprising a storage and fixing component, a drawing fixing component and a support component. The storage and fixing component is a cylindrical structure, comprising a left half cylinder and a right half cylinder that are detachably connected, and a circle of grooves and nesting protrusions are respectively provided on the opposite sides of the left half cylinder and the right half cylinder, and the nesting protrusions are nested and matched with the grooves. The drawing fixing components are respectively arranged at the inner central position of the left half cylinder and the right half cylinder, and the support component comprises two support rods, and the lower ends of the left half cylinder and the right half cylinder are each provided with a fixing sleeve, one end of the support rod is sleeved in the fixing sleeve, and the other end of the support rod is provided with a fixing piece for connecting to the ground.

[0007] The working process and principle of the above structure are as follows:

[0008] When not in use, the supporting assembly is stored in the storing and fixing assembly. Only the storing and fixing assembly needs to be carried. When the drawings need to be displayed, the two supporting rods are respectively inserted into the fixing sleeves of the left half cylinder and the right half cylinder, and the supporting rods are fixed to the ground by the fixing parts. The two vertical sides of the drawings are clamped by the drawing fixing assembly, and the distance between the left half cylinder and the right half cylinder is pulled apart to ensure that the drawings can be stretched and unfolded. The drawings can be unfolded for display. The left half cylinder and the right half cylinder are used as carrying tools, which are lighter and more compact, and the size and weight of various display boards and supporting structures are eliminated. It is more suitable for various environments and is convenient for outdoor drawing display operations.

[0009] Furthermore, the drawing fixing assembly includes an intermediate fixing plate and a clamping plate, the clamping plate includes a support plate and a magnet strip and a first silicone strip arranged on the surface of the support plate, the intermediate fixing plate includes an adsorption plate and a second silicone strip, the adsorption plate is a magnetic metal plate, a push-pull handle is arranged on the upper end of the support plate, the second silicone strip is arranged on the adsorption plate, and the positions of the first silicone strip and the second silicone strip correspond.

[0010] The cooperation between the magnet strip and the adsorption plate provides the main pressing force on the drawing, while the cooperation between the first silicone strip and the second silicone strip increases the friction between the drawing and the clamping plate and the middle fixed plate, thereby preventing the drawing from slipping due to force.

[0011] Furthermore, the first silicone strip has the same length as the magnet strip and the support plate, the thickness of the first silicone strip is 1-2 mm greater than the thickness of the magnet strip, a slot for setting the second silicone strip is formed on the adsorption plate, the second silicone strip is set in the slot, and the plane of the second silicone strip is flush with the plane of the adsorption plate.

[0012] The thickness of the first silicone strip is greater than that of the magnet strip, which helps the first silicone strip to deform under the pressure provided by the magnet strip and the support plate when in contact with the second silicone strip, thereby further increasing the friction between the first silicone strip and the second silicone strip.

[0013] Further, two clamping plates are provided, and the two clamping plates are respectively arranged on both sides of the middle fixing plate. Two second silicone strips are arranged on the adsorption plate, and the two second silicone strips are respectively arranged on both sides of the adsorption plate at positions corresponding to the two first silicone strips. The transverse cross-sectional profile of the adsorption plate is convex-shaped.

[0014] The arrangement of the two clamping plates facilitates the fixing of two drawings or the support and protection structure for fixing a drawing with one of the clamping plates, preventing the drawing from being torn or damaged when subjected to external forces.

[0015] Further, raised balls are uniformly arranged in a rectangular array on the opposite side surfaces of the first silicone strip and the second silicone strip.

[0016] The arrangement of the raised balls further increases the friction between the first silicone strip and the second silicone strip, and increases the clamping force of the clamping plate and the middle fixing plate on the drawing.

[0017] Further, internal threads are provided inside the fixed sleeve. The support rod includes an outer sleeve and a telescopic rod. The lower end of the telescopic rod is slidably connected to the upper end of the outer sleeve. A fixing member is arranged at the lower end of the outer sleeve. External threads are provided at the upper end of the telescopic rod. The telescopic rod is threadedly connected to the fixed sleeve. Two vertical tightening openings are provided at the top end of the side wall of the outer sleeve. The tightening openings are symmetrically arranged on the outer sleeve. External threads are provided on the upper outer surface of the outer sleeve. A tapered sleeve is sleeved on the telescopic rod. A circular through-hole is provided along the axis of the tapered sleeve. The tapered sleeve is sleeved on the telescopic rod through the circular through-hole. One side of the tapered sleeve is disconnected to form a break. A locking nut is sleeved outside the tapered sleeve. The locking nut includes a pressing portion and a threaded portion. Internal threads are provided inside the threaded portion. The inside of the pressing portion is in a tapered structure and fits with the outer surface of the tapered sleeve. The threaded portion of the locking nut is threadedly connected to the outer sleeve.

[0018] First, adjust the telescopic rod to the required extended length. Then, sleeve the tapered sleeve at the position of the tightening opening of the outer sleeve. When screwing the locking nut, the pressing portion of the locking nut gives the tapered sleeve a squeezing force, causing the tapered sleeve to drive the upper part of the outer sleeve to contract inward, thereby clamping the telescopic rod and realizing the fixation of the telescopic rod.

[0019] Furthermore, the fixing member includes an intermediate connecting column and a plurality of supporting legs arranged on the peripheral side of the intermediate connecting column, the supporting legs are in the form of an arc-shaped plate structure, and the plurality of supporting legs are combined to form a cylindrical structure, the top of the supporting leg is hinged to the top of the intermediate connecting column, and a connecting rod is hinged to the middle inner side of each supporting leg, the connecting rod is in the form of an I-shaped structure, and the two horizontal sections protruding outward at both ends of the connecting rod are both cylindrical structures, and a sliding groove is provided on the side surface of the intermediate connecting column corresponding to each connecting rod along the axial direction of the intermediate connecting column, the lower end of the sliding groove is through, and the cross-sectional profile of the sliding groove is T-shaped, the lower end of each supporting leg is in the form of a triangle, the length of the supporting leg is greater than the length of the intermediate connecting column, and the lower end of the intermediate connecting column is in the form of a cone.

[0020] When the ground is harder or there is no need to insert the support legs into the ground, all the support legs are unfolded. The setting of the connecting rod ensures that the support legs are fixed at a certain angle. The setting of the slide groove facilitates the sliding of the connecting rod, and cooperates with the expansion or contraction of the support legs. Through the expansion of multiple support legs, a support base is formed, thereby fixing the support rod and the left half cylinder or the right half cylinder; the connecting rod and the support leg are connected in a detachable hinged manner, and an articulated seat is provided at the hinge of the support leg. The cross-section of the articulated seat on the support leg is C-shaped, and the articulated end of the connecting rod can be removed from the articulated seat of the support leg; when the fixing part needs to be inserted into a softer ground, the supporting leg can be retracted, and then the triangular structure of the supporting leg is used to insert it into the ground. When the insertion structure of the supporting leg is not sufficient to support the fixation, the connecting rod can also be removed, the supporting leg can be lifted up, and directly inserted into the ground through the conical structure of the middle connecting column, so that the fixation is more firm.

[0021] Furthermore, a supporting protective cloth is connected between the left half cylinder and the right half cylinder via a drawing fixing assembly, and both side edges of the supporting protective cloth are fixed by a clamping plate and a middle fixing plate.

[0022] When the wind is slightly stronger, the supporting protective cloth can not only protect the drawings and share the tension and wind impact on the drawings, but also play a shading role to prevent the drawings from being transparent and affecting viewing. At the same time, it can also support the drawings to prevent them from shaking. The clamping plate and the middle fixed plate can also fix some thinner hard boards to provide the same protection. Of course, when the wind is particularly strong, the drawings will definitely not be displayed through this equipment at this time.

[0023] Furthermore, a C-shaped clamp is provided in both the left half cylinder and the right half cylinder, and the support rod is clamped on the C-shaped clamp.

[0024] The C-shaped clamp is mainly provided to facilitate the limiting and fixing of the support rod, so as to prevent the support rod from rolling freely in the storage and fixing assembly during carrying.

[0025] Further, a first connecting ring is provided at the top of the left half cylinder, and a second connecting ring is provided at the lower part of the right half cylinder. A shoulder strap is detachably connected between the first connecting ring and the second connecting ring, and a storage bag is arranged on the shoulder strap.

[0026] Through the cooperation of the first connecting ring, the second connecting ring and the shoulder strap, the storage and fixing component is carried on the back, making it more convenient to carry.

[0027] When using the portable drawing outdoor display device for architectural design of the present invention, when not in use, the support component is stored in the storage and fixing component, and only the storage and fixing component needs to be carried. When it is necessary to display the drawing, the two support rods are respectively sleeved into the fixing sleeves of the left half cylinder and the right half cylinder, and the support rods are fixed to the ground through the fixing parts. The two vertical sides of the drawing are clamped by the drawing fixing component, the distance between the left half cylinder and the right half cylinder is pulled open, and the drawing is unfolded, then the display can be carried out. By using the left half cylinder and the right half cylinder as the carrying tools, it is more lightweight and compact, saving the size and weight of various display boards and support structures, being more suitable for various environments and facilitating the outdoor drawing display operation.

Detailed implementation manners

[0043] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0044] The core of the present invention is to provide a portable drawing outdoor display device for architectural design to improve the effective load of the portable drawing outdoor display device for architectural design.

[0045] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Please refer to Figures 1 to 10 , a portable drawing outdoor display device for architectural design disclosed by the present invention includes a storage and fixing component 1, a drawing fixing component 2 and a support component 3. The storage and fixing component 1 includes a left half cylinder 101 and a right half cylinder 102 which are detachably connected. The left half cylinder 101 and the right half cylinder 102 are fixedly connected by a buckle or an elastic fastening ring. Both of them are conventional existing structures and will not be elaborated here. Storage boxes are provided on the outer sides of the left half cylinder 101 and the right half cylinder 102 for placing drawings and other parts. A circle of grooves 103 and nested protrusions 104 are respectively provided on the opposite sides of the left half cylinder 101 and the right half cylinder 102. The nested protrusions 104 are nested and matched with the grooves 103. The grooves 103 on the left half cylinder 101 and the nested protrusions 104 on the right half cylinder 102 can also play a role in connection and fixation, and at the same time can also play a sealing role to prevent water and dust from entering the storage and fixing component 1. The drawing fixing component 2 is respectively arranged at the central positions inside the left half cylinder 101 and the right half cylinder 102. The connection manner between the drawing fixing component 2 and the left half cylinder 101 or the right half cylinder 102 is bolt connection, bonding or the same material and integrally formed. The connection manner adopted in this embodiment is that the drawing fixing component 2 and the left half cylinder 101 or the right half cylinder 102 are of the same material and integrally formed. The support component 3 includes two support rods 301. A fixing sleeve 105 is provided at the lower end of each of the left half cylinder 101 and the right half cylinder 102. One end of the support rod 301 is sleeved inside the fixing sleeve 105, and a fixing member 302 for connecting to the ground is provided at the lower end of the support rod 301.

[0047] The working process and principle of the above structure are as follows:

[0048] When not in use, the support component 3 is stored in the storage and fixing component 1, and only the storage and fixing component 1 needs to be carried. When it is necessary to display the drawing 5, the two support rods 301 are respectively sleeved into the fixing sleeves 105 of the left half cylinder 101 and the right half cylinder 102, and the support rods 301 are fixed to the ground through the fixing parts 302. The two vertical sides of the drawing 5 are clamped by the drawing fixing component 2. The distance between the left half cylinder 101 and the right half cylinder 102 is pulled apart to ensure that the drawing 5 can be tightly unfolded. The drawing 5 is unfolded, and then the display can be carried out. Using the left half cylinder 101 and the right half cylinder 102 as the carrying tools, it is more portable and compact, saving the size and weight of various display boards and support structures, and being more suitable for various environments and facilitating the outdoor drawing 5 display operation.

[0049] In another embodiment of the present invention, as Figure 5 , Figure 6 and Figure 11 and Figure 12 shown, the drawing fixing component 2 includes an intermediate fixing plate 201 and a clamping plate 202. The clamping plate 202 includes a support plate 2021, a magnet strip 2022 and a first silicone strip 2023 arranged on the surface of the support plate 2021. The intermediate fixing plate 201 includes an adsorption plate 2011 and a second silicone strip 2012. The adsorption plate 2011 is a magnetic metal plate. A push-pull handle 2024 is arranged at the upper end of the support plate 2021. The arrangement of the push-pull handle 2024 helps to place the clamping plate 202 on the intermediate fixing plate 201 and separate the clamping plate 202 from the intermediate fixing plate 201. The second silicone strip 2012 is arranged on the adsorption plate 2011, and the positions of the first silicone strip 2023 and the second silicone strip 2012 correspond.

[0050] Through the cooperation of the magnet strip 2022 and the adsorption plate, a main pressing force is applied to the drawing 5, while the cooperation of the first silicone strip 2023 and the second silicone strip 2012 increases the friction between the drawing 5 and the clamping plate 202 and the intermediate fixing plate 201, avoiding the drawing 5 from slipping off due to force.

[0051] In another embodiment of the present invention, as Figure 6 shown, the first silicone strip 2023 has the same length as the magnet strip 2022 and the support plate 2021. The thickness of the first silicone strip 2023 is 1-2 mm larger than the thickness of the magnet strip 2022. A groove 2013 for arranging the second silicone strip 2012 is formed on the adsorption plate 2011. The second silicone strip 2012 is arranged in the groove 2013, and the plane of the second silicone strip 2012 is flush with the plane of the adsorption plate 2011.

[0052] The thickness of the first silicone strip 2023 is greater than that of the magnet strip 2022, which helps the first silicone strip 2023 to deform under the pressure provided by the magnet strip 2022 and the support plate 2021 when it contacts the second silicone strip 2012, further increasing the friction between the first silicone strip 2023 and the second silicone strip 2012.

[0053] In another embodiment of the present invention, as Figure 5 , Figure 6 , Figure 11 and Figure 12 shown, there are two clamping plates 202, and the two clamping plates 202 are respectively arranged on both sides of the middle fixing plate 201. There are two second silicone strips 2012 on the adsorption plate, and the two second silicone strips 2012 are respectively arranged on both sides of the adsorption plate 2011 at positions corresponding to the two first silicone strips 2023. The transverse cross-sectional profile of the adsorption plate 2011 is convex. A limiting top plate 2014 is horizontally extended at one end of the adsorption plate 2011 close to the fixed sleeve 105. The lower end of the clamping plate 202 abuts against the limiting top plate 2014. When the clamping plate 202 is fixed, the clamping plate 202 directly abuts against the limiting top plate 2014 for quick positioning, avoiding the situation that the clamping plate 202 is misaligned with the middle fixing plate 201.

[0054] The setting of the two clamping plates 202 facilitates the fixing of the two drawings 5 or the support protection structure for fixing the drawing 5 by one of the clamping plates 202, preventing the drawing 5 from being torn or damaged when subjected to external forces.

[0055] In another embodiment of the present invention, as Figure 6 shown, raised balls 203 arranged in a rectangular array are evenly distributed on the opposite side surfaces of the first silicone strip 2023 and the second silicone strip 2012, and the raised balls 203 on the first silicone strip 2023 and the second silicone strip 2012 are arranged in a staggered manner.

[0056] The setting of the raised balls further increases the friction between the first silicone strip 2023 and the second silicone strip 2012, and increases the clamping force of the clamping plate 202 and the middle fixing plate 201 on the drawing 5.

[0057] In another embodiment of the present invention, as Figure 7As shown, an internal thread is provided inside the fixed sleeve 105. The support rod 301 includes a cylindrical outer sleeve 3011 and a telescopic rod 3012. The lower end of the telescopic rod 3012 is slidably connected to the upper end of the outer sleeve 3011. A fixing member 302 is provided at the lower end of the outer sleeve 3011. An external thread is provided at the upper end of the telescopic rod 3012. The telescopic rod 3012 is threadedly connected to the fixed sleeve 105. Two vertical tightening openings 3013 are provided at the top of the side wall of the outer sleeve 3011. A flexible friction pad, such as a rubber pad, is provided on the inner side of the outer sleeve 3011 at the height position corresponding to the tightening openings 3013. The tightening openings 3013 are symmetrically arranged on the outer sleeve 3011. An external thread is provided at the upper end of the outer surface of the outer sleeve 3011. A tapered sleeve 3014 is sleeved on the telescopic rod 3012. A circular through-hole is provided along the axis of the tapered sleeve 3014. The tapered sleeve 3014 is sleeved on the telescopic rod 3012 through the circular through-hole. One side of the tapered sleeve 3014 is disconnected to form a long strip-shaped break. A locking nut 3015 is sleeved outside the tapered sleeve 3014. The locking nut 3015 includes a pressing portion 3016 and a threaded portion 3017. An internal thread is provided inside the threaded portion 3017. The inside of the pressing portion 3016 is in a tapered structure and fits with the outer surface of the tapered sleeve 3014. The threaded portion 3017 of the locking nut 3015 is threadedly connected to the outer sleeve 3011.

[0058] First, adjust the telescopic rod 3012 to the required extended length. Then, sleeve the tapered sleeve 3014 at the position of the tightening openings 3013 of the outer sleeve 3011. When the locking nut 3015 is screwed, the pressing portion 3016 of the locking nut 3015 gives a squeezing force to the tapered sleeve 3014, causing the upper part of the outer sleeve 3011 driven by the tapered sleeve 3014 to contract inward, thereby clamping the telescopic rod 3012 and realizing the fixation of the telescopic rod 3012.

[0059] In another embodiment of the present invention, as Figure 8 and Figure 9 shown, the fixing member 302 includes an intermediate connecting column 3021 and a plurality of support legs 3022 arranged on the periphery of the intermediate connecting column 3021. The support legs 3022 are in an arc-shaped plate structure. The plurality of support legs 3022 are combined to form a cylindrical structure. The top of the support legs 3022 is hinged to the top of the intermediate connecting column 3021. A connecting rod 3023 is hinged in the middle of the inner side of each support leg 3022. The connecting rod 3023 is in an I-shaped structure. The two horizontal sections protruding outward at both ends of the connecting rod 3023 are both cylindrical structures. A sliding groove 3024 is provided on the side surface of the intermediate connecting column 3021 along the axis direction of the intermediate connecting column 3021 corresponding to each connecting rod 3023. The lower end of the sliding groove 3024 is penetrated. The cross-sectional profile of the sliding groove 3024 is T-shaped. The lower end of each support leg 3022 is triangular. The length of the support leg 3022 is greater than the length of the intermediate connecting column 3021. The lower end of the intermediate connecting column 3021 is in a tapered structure.

[0060] When on a harder ground or when there is no need to insert into the ground, all the support legs 3022 are unfolded. The setting of the connecting rod 3023 ensures that the support legs 3022 are fixed at a certain angle. The setting of the sliding groove 3024 facilitates the sliding of the connecting rod 3023, and cooperates with the unfolding or contraction of the support legs 3022. By unfolding multiple support legs 3022, a support base is formed, thereby fixing the support rod 301 and the left half cylinder 101 or the right half cylinder 102; the connecting rod 3023 and the support legs 3022 are connected by a detachable hinge method. A hinge seat is provided at the hinge of the support legs 3022. The cross-section of the hinge seat on the support legs 3022 is C-shaped, and the hinge end of the connecting rod 3023 can be taken off from the hinge seat of the support legs 3022; when it is necessary to insert the fixing member 302 into a softer ground, the support legs 3022 can be contracted, and then the triangular structure of the support legs 3022 is used to insert into the ground. When the insertion structure of the support legs 3022 is not sufficient to support and fix, the connecting rod 3023 can also be removed, the support legs 3022 can be lifted, and the conical structure of the middle connecting column 3021 is directly inserted into the ground, making the fixation more firm.

[0061] In another embodiment of the present invention, as Figure 2 shown, a support protection cloth 4 is connected between the left half cylinder 101 and the right half cylinder 102 through a drawing fixing component 2. Both side edges of the support protection cloth 4 are fixed by a clamping plate 202 and a middle fixing plate 201. The support protection cloth 4 can be placed in the storage bag 601 or the storage boxes on both sides of the storage and fixing component 1, or can be rolled into a cylindrical shape and placed in the storage and fixing component 1.

[0062] When the wind is slightly strong, through the setting of the support protection cloth 4, it can not only protect the drawing 5, share the tensile force and the influence of the wind received by the drawing 5, but also play a role in shading, avoiding the drawing 5 from transmitting light and affecting the viewing, and at the same time can also play a supporting role for the drawing 5 to avoid the drawing 5 from shaking. Moreover, the clamping plate 202 and the middle fixing plate 201 can also cooperate to fix some hard boards with a relatively thin thickness, and also provide a protective effect. Of course, when the wind is extremely strong, it is certainly not possible to display the drawing 5 through this equipment at this time.

[0063] In another embodiment of the present invention, as Figure 5 shown, C-shaped clamps 106 are provided in both the left half cylinder 101 and the right half cylinder 102, and the support rod 301 is clamped on the C-shaped clamps 106. Four C-shaped clamps 106 are provided in the left half cylinder 101. The four C-shaped clamps 106 are divided into two groups, and are respectively located on both sides of the drawing fixing component 2.
