Description

Technical Field

[0001] This utility model relates to the field of drawing table technology, and in particular to a multifunctional drawing table. Background Technology

[0002] With the development of information technology, drawing has seen rapid advancements in art creation, computer art, and engineering drawing. In practical work, computers have gradually replaced traditional hand-drawing, offering advantages such as simplicity, efficiency, and practicality. However, hand-drawing, as one of the essential basic skills for designers, cannot be ignored; the adjustment, recognition, and proportioning of colors still rely on hand-drawing. Simply put, a drawing table is a tool used by drafters to hold drawing paper and smoothly complete drawing operations. Drafting courses are a key focus for students in engineering majors, especially mechanical engineering, civil engineering, and architecture. Through practical drawing exercises in drafting courses, students develop the skills to read and draw blueprints.

[0003] Existing drawing tables generally have fixed height and angle, and the tabletop height and angle cannot be effectively adjusted. This makes it impossible to customize the drawing table to suit different people, making it difficult to achieve one-to-many tasks. People of different heights and builds will find it inconvenient to use. The drawing table has limited functions and cannot well adapt to different work needs. Therefore, this application provides a multifunctional drawing table to meet the needs. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a multifunctional drawing table to address the issues of existing drawing tables, which generally have fixed height and angle, cannot effectively adjust the table height and angle, cannot be customized to suit different people, are difficult to achieve one-to-many tasks, cause inconvenience for people of different heights and builds, and have limited functionality, failing to adequately meet diverse work needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A multifunctional drawing table includes a receiving box, a base at the bottom of the receiving box, a support rod fixed between the base and the receiving box, an installation cavity at the top of the receiving box, a receiving plate inside the installation cavity, a hinge plate hinged at the top of the receiving plate, and a sliding cavity at the bottom of the installation cavity, with a support component for assisting in adjusting the height of the receiving plate inside the sliding cavity.

[0007] The support assembly includes a threaded rod rotatably disposed within a sliding cavity, a sliding plate symmetrically disposed on the threaded rod, two threads with opposite helical directions symmetrically disposed on the threaded rod, the sliding plate and the threaded rod being threadedly engaged, an X-shaped hinge frame hingedly mounted at the top of the sliding plate, and a hinge seat hingedly mounted at the top of the hinge frame, the hinge seat being slidably embedded at the bottom of the receiving plate.

[0008] Optionally, one end of the threaded rod extends out of the sliding cavity, and a knob is fixed to the end of the threaded rod extending out of the sliding cavity.

[0009] Optionally, guide grooves are symmetrically provided on the top of the mounting cavity and on both sides corresponding to the sliding cavity. A guide rod is fixed laterally in the guide groove. A guide block is symmetrically protruding at the bottom of the slide plate. The guide block is sleeved on the guide rod.

[0010] Optionally, the hinge plate has symmetrical sliding cavities on both sides, and a support assembly for assisting in adjusting the position of the hinge plate is provided between the sliding cavities and the side of the receiving plate.

[0011] Optionally, the supporting assembly includes a sliding column slidably disposed in the sliding cavity, and a support rod is hinged between the sliding column and the receiving plate.

[0012] Optionally, a positioning hole is provided on the inner side of the sliding cavity, and a positioning component that cooperates with the positioning hole is provided inside the sliding column.

[0013] Optionally, the positioning component includes an insert block rotatably mounted in a slide column, one end of the insert block is fixed with a lead screw, a positioning pin is sleeved on the lead screw, the lead screw and the positioning pin are threadedly engaged, and the positioning pin and the positioning hole are threadedly engaged.

[0014] Optionally, a plurality of positioning holes are provided, and the plurality of positioning holes are equally spaced in the sliding cavity.

[0015] Optionally, a protruding strip is fixedly protruding from the top of the hinge plate at the hinge end, and a clamping cavity is provided at the end of the hinge plate away from the protruding strip, and a clamping assembly for assisting in clamping the drawing board is provided in the clamping cavity.

[0016] Optionally, the clamping assembly includes a slide rod slidably disposed in the clamping cavity and a C-shaped clamping block, one end of the slide rod being fixed to the clamping block, and an elastic pressure plate protruding from the clamping block.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by using a support component set at the top of the receiving box, rotating the knob drives the threaded rod to rotate. The threaded rod engages with the sliding plate, causing the sliding plate to move and the hinge frame to unfold. This allows the overall height of the receiving plate to be adjusted to accommodate the needs of people of different heights and avoids problems such as the inability to effectively adjust the desktop height, which affects the use of the staff.

[0019] By cooperating with the supporting components and positioning components, when the angle of the hinge plate needs to be adjusted, the hinge plate is pre-rotated to the specified angle. At this time, the slide column moves along the slide cavity, reverses the embedded block, and drives the lead screw to rotate when the embedded block rotates. The lead screw and the positioning pin are threaded together, so that the positioning pin is inserted into the positioning hole, thereby completing the overall adjustment of the position of the slide column.

[0020] By coordinating the clamping components, the slide can be directly snapped into the clamping block before drawing, and the elastic pressure plate can provide elastic auxiliary clamping to the drawing board. At this point, the drawing paper can be placed on the drawing board. Attached Figure Description

[0034] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a multifunctional drawing table, including a receiving box 1. A base 19 is provided at the bottom of the receiving box 1, and a support rod 20 is fixed between the base 19 and the receiving box 1. An installation cavity is provided at the top of the receiving box 1, and a receiving plate 2 is provided in the installation cavity. A hinge plate 3 is hingedly installed at the top of the receiving plate 2. A sliding cavity is provided at the bottom of the installation cavity, and a support component 4 for assisting in the height adjustment of the receiving plate 2 is provided in the sliding cavity. The support component 4 includes a threaded rod 7 rotatably disposed in the sliding cavity. One end of the threaded rod 7 extends out of the sliding cavity, and a knob 71 is fixed at the end of the threaded rod 7 extending out of the sliding cavity. A sliding plate 5 is symmetrically disposed on the threaded rod 7. Two threads with opposite helical directions are symmetrically disposed on the threaded rod 7. The sliding plate 5 and the threaded rod 7 are threadedly engaged. An X-shaped hinge frame 6 is hingedly installed at the top of the sliding plate 5, and a hinge seat is hingedly installed at the top of the hinge frame 6. The hinge seat is slidably embedded in the bottom of the receiving plate 2.

[0035] By rotating the knob 71 through the support component 4 located at the top of the housing box 1, the knob 71 rotates, causing the threaded rod 7 to rotate. The threaded rod 7 and the slide plate 5 are threadedly engaged, thereby moving the slide plate 5 and unfolding the hinge frame 6. This allows the overall height of the receiving plate 2 to be adjusted to meet the needs of people of different heights.

[0036] The top of the mounting cavity and the two sides corresponding to the sliding cavity are symmetrically provided with guide grooves. A guide rod 8 is fixed horizontally in the guide groove. A guide block 51 is symmetrically protruding at the bottom of the slide plate 5. The guide block 51 is sleeved on the guide rod 8. Through the cooperation between the guide block 51 and the guide rod 8, the slide plate 5 will not be misaligned when it is adjusted.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, the hinge plate 3 has symmetrical sliding cavities on both sides. A support assembly 9 for adjusting the position of the hinge plate 3 is provided between the sliding cavity and the side of the receiving plate 2. The support assembly 9 includes a sliding column 32 slidably disposed in the sliding cavity. A support rod 10 is hingedly installed between the sliding column 32 and the receiving plate 2. A positioning hole 11 is provided on the inner side of the sliding cavity. Several positioning holes 11 are provided and are equidistantly arranged in the sliding cavity. A positioning assembly 12 is provided in the sliding column 32 to cooperate with the positioning hole 11 for positioning. The positioning assembly 12 includes an embedding block 13 rotatably embedded in the sliding column 32. A screw rod 14 is fixed to one end of the embedding block 13. A positioning pin 15 is sleeved on the screw rod 14. The screw rod 14 and the positioning pin 15 are threadedly engaged. The positioning pin 15 and the positioning hole 11 are threadedly engaged.

[0038] Through the cooperation between the supporting component 9 and the positioning component 12, when the angle of the hinge plate 3 needs to be adjusted, the hinge plate 3 is pre-rotated to the specified angle. At this time, the sliding column 32 moves along the sliding cavity, and the reverse-mounted insert block 13 rotates. When the insert block 13 rotates, it drives the lead screw 14 to rotate. The lead screw 14 and the positioning pin 15 are threaded together, so that the positioning pin 15 is inserted into the positioning hole 11, thereby completing the overall adjustment of the position of the sliding column 32. This effectively determines the tilt angle of the hinge plate 3, so that the hinge plate 3 can maintain a tilt state with different tilt degrees to adapt to different working requirements.

[0039] The hinge plate 3 has a protruding strip 31 fixed at the top corresponding to the hinge end. The end of the hinge plate 3 away from the protruding strip 31 is provided with a clamping cavity. The clamping cavity is provided with a clamping assembly 16 for assisting in clamping the drawing board. The clamping assembly 16 includes a slide rod 18 slidably disposed in the clamping cavity and a C-shaped clamping block 17. One end of the slide rod 18 is fixed on the clamping block 17. An elastic pressure plate 171 is protruding on the clamping block 17.

[0040] By cooperating with the clamping components 16, the drawing board can be directly snapped into the clamping block 17 before drawing, and the elastic pressure plate 171 can provide elastic auxiliary clamping treatment for the drawing board. At this time, the drawing paper can be placed on the drawing board.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] When it is necessary to unfold the entire receiving plate 2, turn the knob 71. When the knob 71 is turned, it drives the threaded rod 7 to rotate. The threaded rod 7 and the sliding plate 5 are threaded together, thereby moving the sliding plate 5 and unfolding the hinge frame 6, thereby adjusting the overall height of the receiving plate 2.

[0043] After the pre-hinged plate 3 is rotated to the specified angle, the sliding column 32 moves along the sliding cavity and reverses the embedded block 13. When the embedded block 13 rotates, it drives the lead screw 14 to rotate. The lead screw 14 and the positioning pin 15 are threaded together, so that the positioning pin 15 is inserted into the positioning hole 11, thereby completing the overall adjustment of the position of the sliding column 32 and effectively determining the tilt angle of the hinged plate 3.

[0044] Before drawing, the drawing board is directly snapped into the clamping block 17, and the elastic pressure plate 171 provides elastic auxiliary clamping for the drawing board. At this time, the drawing paper can be placed on the drawing board.

[0045] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
