Description

Technical Field

[0001] The present invention relates to the technical field of land and resources display devices, and specifically relates to a display device for national land space planning and layout. Background Art

[0002] Land and resources are the material basis for a country and its residents to survive, and are a material entity composed of natural resources and social and economic resources. Narrowly defined, land and resources only include natural resources such as land, rivers, lakes and seas, minerals, organisms, and climate. Broadly defined, land and resources also include population resources and social and economic resources. In the process of promoting land and resources management, it is necessary to use display devices to display the national land space planning and layout.

[0003] The prior art discloses an invention technical solution of a planar display device for national land space planning and layout, and the authorization announcement number is: CN113598553B. This invention can move two translation frames towards or away from each other through the provided translation adjustment mechanism. The translation frame drives the clamping assembly to straighten the drawing used for national land space planning and layout, so as to fully display the planning content in the drawing. The specific structure of this invention includes a moving frame. A vertically arranged bearing frame is installed on the moving frame through a height adjustment mechanism. Two relatively arranged translation frames are slidably installed on the bearing frame. A guide plate is installed on the translation frame, and an extension sleeve is slidably sleeved on the guide plate. One end of the extension sleeve away from the translation frame is installed with a clamping assembly for fixing the edge of the drawing. A protective cover is installed on the bearing frame, and a translation adjustment mechanism for driving the two translation frames to move towards or away from each other is arranged in the protective cover. A locking mechanism is installed on the extension sleeve, and the locking mechanism is used to lock and fix the guide plate and the extension sleeve. An unlocking mechanism is arranged on the bearing frame, and the unlocking mechanism is used to trigger the separation of the locking mechanism and the guide plate.

[0004] Although the current technical solution can move two translation frames towards or away from each other through the translation adjustment mechanism to straighten the drawing used for national land space planning and layout, so as to fully display the planning content in the drawing, there are still a series of technical problems to be solved. Specifically, 1. The manual translation adjustment mechanism constructed by gears and racks has a complex and heavy structure, a large thickness dimension, is laborious to adjust, and has no self-locking ability. 2. The structures of the two translation frames need to be additionally provided with a locking mechanism to lock the specific position after adjustment, which significantly increases the operation complexity of the user, and the locking mechanism increases the weight of the extension sleeve, resulting in a sagging problem. 3. When the two translation frames move away from each other to expand the size, it relies on the mutual telescopic sliding structure between the extension sleeve and the guide plate. Then, as the size expands, the overlapping part between the extension sleeve and the guide plate becomes less, resulting in insufficient support of the guide plate for the extension sleeve, and the part where the extension sleeve is located will sag, which is not conducive to drawing display. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a display device for the layout of territorial space planning, which helps to overcome the problems of the prior art.

[0006] The technical solution of the present invention is: a display device for the layout of territorial space planning, including a bracket and a back frame, and also including a front panel. The front panel is connected to the back frame to form a sandwich layer, which is supported by the bracket, and a moving structure is arranged inside the sandwich layer.

[0007] The moving structure includes a left frame and a right frame symmetrically arranged on the left and right. An electric motor is arranged between the left frame and the right frame. A first vertical side rod is arranged on the left side of the electric motor on the left frame, and a second vertical side rod is arranged on the right side of the electric motor on the right frame. The first vertical side rod is provided with a first nut and a first lead screw, and the second vertical side rod is provided with a second nut and a second lead screw.

[0008] The left frame further includes a first cross bar and a second cross bar sequentially arranged up and down along the first vertical side rod. The first cross bar connects a first sliding support and a second sliding support, and the second cross bar connects a third sliding support and a fourth sliding support. The right frame further includes a third cross bar and a fourth cross bar sequentially arranged up and down along the second vertical side rod. The third cross bar connects a fifth sliding support and a sixth sliding support, and the fourth cross bar connects a seventh sliding support and an eighth sliding support.

[0009] The electric motor is used to drive the first lead screw and the second lead screw to rotate simultaneously, so as to drive the left frame and the right frame to move towards or away from each other left and right at the same time.

[0010] The first cross bar and the second cross bar are connected with a left holding part, and the third cross bar and the fourth cross bar are connected with a right holding part. The front panel is provided with a left slot and a right slot. The left holding part moves left and right through cooperation with the left slot, and the right holding part moves left and right through cooperation with the right slot.

[0011] After adopting the above structure, the present invention has the following advantages:

[0012] Through improvements, the present disclosure achieves a hidden design through a sandwich design. In addition, the first crossbar is slidably supported by a first sliding support and a second sliding support, and the second crossbar is slidably supported by a third sliding support and a fourth sliding support. Therefore, the left frame is slidably supported by the first sliding support, the second sliding support, the third sliding support, and the fourth sliding support, and good support is obtained throughout the adjustment stroke, and it is not easy to sag. Similarly, the right frame is slidably supported by a fifth sliding support, a sixth sliding support, a seventh sliding support, and an eighth sliding support, and good support is obtained throughout the adjustment stroke, and it is not easy to sag. In this way, both the left frame and the right frame are well supported. Moreover, an electric motor is provided between the left frame and the right frame, and the electric motor drives the first lead screw and the second lead screw to rotate simultaneously, thereby driving the left frame and the right frame to move towards / away from each other left and right at the same time. The present disclosure accommodates the structure in the sandwich layer, on the one hand, significantly reducing the thickness, avoiding complex and bulky structures, large thickness dimensions, and laborious adjustment. On the other hand, by utilizing the self-locking ability of the cooperation between the lead screw and the nut, the locking mechanism in the prior art can be cancelled, avoiding weight gain and enabling more precise adjustment. On the third hand, adopting the sliding support scheme is beneficial to more stable support and avoids the problem of sagging in the prior art.

[0013] In some embodiments, the first sliding support, the second sliding support, the third sliding support, the fourth sliding support, the fifth sliding support, the sixth sliding support, the seventh sliding support, and the eighth sliding support are all fixed on the back frame, the back frame is fixed on the bracket, and the front panel is detachably connected to the back frame to form a sandwich layer.

[0014] In some embodiments, the back frame is provided with hooks, the front panel is hung on the hooks in the up-down direction, and the left slot and the right slot are both provided with the opening width for hanging in the up-down direction.

[0015] In some embodiments, the left frame further includes a left vertical side bar, the left vertical side bar is respectively connected to the first crossbar and the second crossbar, and left holding parts are sequentially arranged on the left vertical side bar in the vertical direction. The right frame further includes a right vertical side bar, the right vertical side bar is respectively connected to the third crossbar and the fourth crossbar, and right holding parts are sequentially arranged on the right vertical side bar in the vertical direction.

[0016] In some embodiments, both the left holding part and the right holding part adopt magnetic holding parts. The magnetic holding part includes a front part and a rear part, and the front part and the rear part are magnetically attracted to each other front and back, and the clamping surface between the front part and the rear part serves as the clamping part.

[0017] In some embodiments, left slots and right slots are respectively arranged at the four corners of the front panel, and the left holding parts and the right holding parts are also correspondingly arranged at the four corners of the front panel, and the inner part of the front panel serves as a writing area.

Detailed Embodiments

[0026] In order to better understand the present application, more detailed descriptions of various aspects of the present application will be made with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of the exemplary embodiments of the present application and do not limit the scope of the present application in any way.

[0027] As Figures 1 to 5 shown, a national land space planning and layout display device is disclosed, which includes a bracket 1 and a back frame 2, and further includes a front panel 3. The front panel 3 is connected to the back frame 2 to form a sandwich layer, which is supported by the bracket 1, and a moving structure is arranged inside the sandwich layer.

[0028] In this example, the backrest 2 is set as a back panel, and both the back panel and the front panel 3 are rectangular plates. Then, the sandwich layer forms a rectangular space. Since there is occlusion on both the front and the back, the moving structure is well protected within the sandwich layer. At the same time, it is not easy for the user to touch the internal structure and cause injury.

[0029] Particularly, due to the setting of the front panel 3, the drawing can be supported flat on the front panel 3, with better support. In addition, due to the formation of the sandwich structure, the integrity of the overall structure is also better, which is also beneficial for better manufacturing of the appearance.

[0030] As Figure 1 shown, the moving structure includes a left side frame 4 and a right side frame 5 which are symmetrically arranged left and right. An electric motor 6 is arranged between the left side frame 4 and the right side frame 5. A first vertical side rod 7 is arranged on the left side of the electric motor 6 on the left side frame 4, and a second vertical side rod 8 is arranged on the right side of the electric motor 6 on the right side frame 5. A first nut 9 and a first lead screw 10 are arranged on the first vertical side rod 7, and a second nut 11 and a second lead screw 12 are arranged on the second vertical side rod 8.

[0031] The left side frame 4 further includes a first cross bar 13 and a second cross bar 14 which are sequentially arranged up and down along the first vertical side rod 7. The first cross bar 13 connects a first sliding support 15 and a second sliding support 16, and the second cross bar 14 connects a third sliding support 17 and a fourth sliding support 18. The right side frame 5 further includes a third cross bar 19 and a fourth cross bar 20 which are sequentially arranged up and down along the second vertical side rod 8. The third cross bar 19 connects a fifth sliding support 21 and a sixth sliding support 22, and the fourth cross bar 20 connects a seventh sliding support 23 and an eighth sliding support 24.

[0032] The electric motor 6 is used to drive the first lead screw 10 and the second lead screw 12 to rotate simultaneously, so as to drive the left side frame 4 and the right side frame 5 to move left and right towards each other / away from each other simultaneously.

[0033] The first cross bar 13 and the second cross bar 14 are connected with a left holding part 25, and the third cross bar 19 and the fourth cross bar 20 are connected with a right holding part 26. The front panel 3 is provided with a left slot 27 and a right slot 28. The left holding part 25 moves left and right through cooperation with the left slot 27, and the right holding part 26 moves left and right through cooperation with the right slot 28.

[0034] As Figure 1 shown, the first cross bar 13 and the second cross bar 14 are arranged parallel to each other up and down, and the third cross bar 19 and the fourth cross bar 20 are also arranged parallel to each other up and down. Although the first cross bar 13 is supported by two sliding supports, the number of sliding supports can be three or more. Such a setting is also applicable to the second cross bar 14, the third cross bar 19, and the fourth cross bar 20.

[0035] The setting of the sliding supports also brings additional advantages. That is, the first cross bar 13, the second cross bar 14, the third cross bar 19, and the fourth cross bar 20 are all supported by their respective sliding supports, avoiding large vertical forces on the first vertical side bar 7 and the second vertical side bar 8. Therefore, the first lead screw 10 connected to the first vertical side bar 7 and the second lead screw 12 connected to the second vertical side bar 8 are subject to smaller radial forces, and can more smoothly push the first vertical side bar 7 and the second vertical side bar 8 to move left and right, thereby improving the reliability of the present disclosure, as well as the smoothness and accuracy of the movement.

[0036] To further provide good rotational support for the first lead screw 10 and the second lead screw 12, as Figure 1 shown, the first lead screw 10 is further connected to a left rotating support 33, and the second lead screw 12 is further connected to a right rotating support 34.

[0037] To further simplify the structure, the electric motor 6 is a double-output shaft electric motor 6, that is, the left output shaft of the electric motor 6 is connected to the first lead screw 10, and the right output shaft of the electric motor 6 is connected to the second lead screw 12. The first mating thread between the first nut 9 and the first lead screw 10 and the second mating thread between the second nut 11 and the second lead screw 12 are just opposite. In this way, when the electric motor 6 rotates, it can synchronously drive the left side frame 4 and the right side frame 5 to move towards or away from each other left and right, thereby providing better control accuracy, and the structure is compact, which is beneficial to controlling the weight and thickness dimensions.

[0038] In some embodiments, for the convenience of assembly and later maintenance, as Figure 1 、 3 shown, the first sliding support 15, the second sliding support 16, the third sliding support 17, the fourth sliding support 18, the fifth sliding support 21, the sixth sliding support 22, the seventh sliding support 23, and the eighth sliding support 24 are all fixed on the back frame 2, the back frame 2 is fixed on the bracket 1, and the front panel 3 is detachably connected to the back frame 2 to form a sandwich. In this way, the moving structure can be installed on the back frame 2 first, and then the front panel 3 is processed separately, and then the front panel 3 is detachably connected to the back frame 2 to form a sandwich, thus completing the assembly. When maintenance is required, as long as the front panel 3 is removed, the entire moving structure is exposed, which provides great convenience for maintenance.

[0039] Furthermore, for the convenience of disassembly and assembly, as Figure 1 shown, the back frame 2 is provided with hooks 29, and the front panel 3 is hung on the hooks 29 in the vertical direction. The left slot 27 and the right slot 28 are both provided with an opening width for hanging in the vertical direction. In this example, the hooks 29 are arranged on the upper and lower sides of the back frame 2, so as to avoid affecting the moving structure. For the specific number of settings, in this example, as Figure 1As shown, there are three groups of left, middle and right in the left - right direction on the upper side edge, with two in each group. Correspondingly, there are also three groups of left, middle and right in the left - right direction on the lower side edge, with two in each group, thus providing reliable support for the front panel 3. In order to avoid interference during hanging, the width dimensions of the left slot 27 and the right slot 28 in the up - down direction are both set to be larger than the width dimensions of the left holding part 25 and the right holding part 26 in the up - down direction, thus forming a space for up - down hanging connection.

[0040] In some embodiments, as Figure 1 shown, the left frame 4 further includes a left vertical side rod 30. The left vertical side rod 30 is respectively connected to the first cross - bar 13 and the second cross - bar 14. The left holding part 25 is sequentially arranged on the left vertical side rod 30 along the vertical direction. The right frame 5 further includes a right vertical side rod 31. The right vertical side rod 31 is respectively connected to the third cross - bar 19 and the fourth cross - bar 20. The right holding part 26 is sequentially arranged on the right vertical side rod 31 along the vertical direction. In this way, on the one hand, the left vertical side rod 30 and the first vertical side rod 7 are arranged parallel to each other left - right. The left vertical side rod 30, the first vertical side rod 7, the first cross - bar 13 and the second cross - bar 14 form a stable frame structure in the shape of a rectangle. Similarly, the right vertical side rod 31 and the second vertical side rod 8 are arranged parallel to each other left - right. The right vertical side rod 31, the second vertical side rod 8, the third cross - bar 19 and the fourth cross - bar 20 also form a stable frame structure in the shape of a rectangle. On the other hand, the left vertical side rod 30 is also used to set the left holding part 25, and the right vertical side rod 31 is used to set the right holding part 26, thus facilitating the layout of the left holding part 25 and the right holding part 26. At the same time, the left holding part 25 and the right holding part 26 also obtain stable basic support. In particular, the left vertical side rod 30 is extended at the upper and lower ends, and the right vertical side rod 31 can also be extended at the upper and lower ends. Then the left holding part 25 and the right holding part 26 can be closer to the four corners, thus providing a structural basis for the multi - function setting of the present disclosure.

[0041] Furthermore, both the left holding part 25 and the right holding part 26 adopt magnetic holding parts. The magnetic holding part includes a front part and a rear part, and the front part and the rear part are magnetically attracted to each other front - rear. The clamping surface between the front part and the rear part serves as the clamping part. In this way, on the one hand, it is convenient to install the drawing. On the other hand, when the drawing is pulled tightly, the drawing can adaptively loosen, thus avoiding tearing the drawing.

[0042] The innovation of the present disclosure also lies in providing a multi - functional display device for national land space planning layout. Specifically, as Figure 3 、 4 、5 shown, left slots 27 and right slots 28 are respectively arranged at the four corners of the front panel 3. The left holding part 25 and the right holding part 26 are also correspondingly arranged at the four corners of the front panel 3. The inner part of the front panel 3 serves as a writing area 35. In this way, based on the sandwich design and the four - corner design of the left holding part 25 and the right holding part 26, the front panel 3 is not only used to support the drawing, but also the inner part of the front panel 3 serves as a writing area 35.

[0043] Since the moving structures are all installed on the back frame 2 and the front panel 3 is basically not stressed, the front panel 3 can be set as a whiteboard suitable for writing. However, the structure of the whiteboard needs to be adjusted, that is, left slots 27 and right slots 28 are cut out on the whiteboard.

[0044] In particular, as shown in Figure 3 、 4 、5, the front panel 3 is further provided with a temporary storage portion 32, and the temporary storage portion 32 is arranged on the left side and / or the right side of the front panel 3. In this example, the temporary storage portions 32 are arranged on both the left side and the right side of the front panel 3. In this way, when displaying drawings, one end of the drawing can be removed and folded towards the other end of the drawing, and then pressed by the temporary storage portion 32 to achieve temporary storage. At this time, the front panel 3 can be used for writing, and the drawing display and writing demonstration can be flexibly switched to better serve the needs of the national territorial space planning layout display.

[0045] Furthermore, the temporary storage portion 32 adopts a magnetic pressing block, and the pressing block can press the drawing and store it on the front panel 3. This is beneficial for more convenient use.

[0046] The above are only the exemplary embodiments of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the protection scope of the present invention are included in the protection scope of the present invention.
