Description

Technical Field

[0001] The present application relates to the technical field of electric office furniture, and in particular to a quick-install lifting table. Background Art

[0002] A lifting table is an office desk with adjustable height, which can be adjusted according to a person's height, sitting posture and standing posture. It generally includes an electric lifting table and a manual lifting table. The electric lifting table of the prior art, especially the electric lifting table driven by a dual motor, has a structure including a table top, a base, a crossbeam and two liftable table legs. The table top is connected to the top of the crossbeam, the upper ends of the two table legs are connected to the crossbeam, and the lower ends of the two table legs are connected to the base; the top of each table leg is connected to a motor housing, a driving motor is installed in the motor housing, and the rotating shaft of the driving motor is connected to the screw lifting mechanism in the table leg for driving the screw lifting mechanism to rotate so as to raise and lower the table leg; in order to make the connection between the table leg and the table top stable and maintain the stability of the table top during the lifting process, the connection between the table leg and the crossbeam of the electric lifting table of the prior art is generally bolted, that is, a plurality of mounting holes are provided on both sides of the bottom plate of the motor housing, and a plurality of connecting holes corresponding to the mounting holes are provided on the crossbeam, and a locking bolt is connected in the mounting hole, and the locking bolt is threadedly connected in the connecting hole on the crossbeam to achieve the connection between the table leg and the crossbeam. For example, the prior application of the applicant of this case with the publication number CN210184885U and the name of the lifting table. There are at least two mounting holes on both sides of the bottom plate of the motor housing. When the motor housing of the table legs is assembled with the crossbeam, each table leg is connected to the crossbeam by at least four locking bolts, and the installation of the table legs is relatively troublesome; especially when the user buys it for assembly, at least eight screws are required to assemble the two table legs, which takes a long time and is slow to assemble. Moreover, tools must be used, which is relatively troublesome to assemble.

[0003] Another example is the patent application for a lifting table with announcement number CN211722218U and name, which was previously applied by the applicant of this case. The first end of the motor housing in the width direction is rotatably connected to the two inner side walls of the beam assembly through a rotating shaft. Two threaded holes are provided on the two outer side walls of the second end in the width direction of the housing, and two fasteners are threadedly connected to the two threaded holes. The outer ends of the two fasteners are both protruding and arranged on the outside of the housing. The outer ends of the two fasteners are both provided with radially protruding limit column heads. The beam assembly is provided with two clamping holes for the outer ends of the fasteners to be inserted into, and the outer diameter of the limit column heads is larger than the aperture size of the clamping holes. When installing the legs of the lifting table, the outer ends of the fasteners on the two outer side walls of the second end of the driving motor housing are inserted into the clamping holes of the beam, and the second end of the driving motor housing can be fixed to the beam by tightening the two fasteners with a tool.

[0004] The table legs of the electric lift table in the above-mentioned related technology generally have some shortcomings in the actual assembly process: the driving motor housing on the table leg is connected and fixed to the crossbeam by fasteners such as screws or bolts. When assembling the table legs, the user must use manual tools or electric tools to tighten and fix the driving motor housing to the crossbeam, so the assembly is troublesome, slow and laborious; in addition, the degree of tightening of the fasteners determines the assembly accuracy of the driving motor housing, and the degree of tightening of the fasteners needs to be accurately grasped by professional installers. Therefore, when ordinary users assemble the table legs, the assembly accuracy of the table legs is often low, especially after long-term use of the lift table, the fasteners on one side of the table legs are loose, resulting in a poor user experience. Summary of the invention

[0011] In some embodiments, the quick-release lifting table also includes two support plates, which are respectively arranged at both ends of the beam assembly, and each support plate is connected to two connecting columns; the two beams at the ends of the beam assembly are respectively provided with hanging holes corresponding to the two connecting columns, and when the cam assembly rotates to the locking position, the two beams move toward each other so that the two hanging holes squeeze inward and lock the two connecting columns, so that the support plates are fixedly connected to the ends of the beam assembly.

[0012] In some embodiments, the end of the beam is provided with a slot extending along the length direction of the beam and the outer end of which passes through the end surface of the beam, and the width of the slot is larger than the outer diameter of the connecting column; the hanging hole is arranged on the side wall of the slot away from the center of the beam assembly.

[0013] In some embodiments, the connecting column includes a first connecting member vertically connected to the support plate and a second connecting member threadedly connected to the first connecting member, the lower end of the second connecting member is provided with an anti-slip column head with an outer diameter larger than the aperture size of the hanging hole, and the outer side wall of the second connecting member is set to a conical surface with a smaller top and a larger bottom.

[0014] In some embodiments, there are two locking rods, and the two locking rods are respectively connected to the cam assembly; the motor housing is provided with two groups of slots that are respectively matched with the two locking rods for positioning; when the motor housing is accommodated in the installation space, the two groups of slots are respectively engaged with the two locking rods.

[0015] In some embodiments, two opposite side walls of the motor housing are respectively connected with a clamping plate, and two groups of the clamping slots are respectively arranged on the two clamping plates, and the openings of the clamping slots are arranged upward.

[0016] In some embodiments, a first positioning structure is provided on the inner walls of the two beams of the installation space, and a second positioning structure is provided on the clamping plates on both sides of the motor housing. The first positioning structure and the second positioning structure are matched and plugged in to limit the rotation of the table legs relative to the beam assembly.

[0017] In some embodiments, the first positioning structure is a socket disposed on the inner wall of the beam, and the second positioning structure is a plug disposed on the clamping plate and plugged into the socket.

[0018] In some embodiments, a main shaft is connected inside the cam assembly, and the main shaft is rotatably connected to the two locking rods respectively.

[0019] In some embodiments, the cam assembly is provided with a handle portion for driving the cam assembly to rotate, and the handle portion is provided with a limiting plane for abutting against the bottom plane of the beam assembly when the cam assembly is rotated to a locking position, so as to make up for the gap between the locking rod and the beam.

[0020] In some embodiments, the cam assembly is provided with a handle portion for driving the cam assembly to rotate, the handle portion is connected to a buckle, and the free end of the buckle is provided with a buckle head; when the cam assembly is rotated to a locking position, the buckle is located below the beam assembly and the buckle head is buckled onto the first beam.

[0021] In summary, compared with the related art, the quick-install lifting table of the present application has the following advantages: the two beams of the quick-install lifting table beam assembly can move relative to each other, so that the spacing of the installation space formed between the two beams can be changed; and the quick-install lifting table also includes a locking mechanism connected to the beam assembly, the locking mechanism consists of a locking rod and a cam assembly, and the cam assembly is rotated. Under the action of the locking rod, the cam portion of the cam assembly can squeeze the second beam inwardly, so that the two beams move toward each other to press the motor housing in the installation space, and when unlocking, it is only necessary to rotate the cam assembly in the opposite direction, and the cam portion releases the squeezing of the second beam, so that the two beams release the motor housing in the installation space; therefore, when installing the lifting table legs of the quick-install lifting table, it is only necessary to insert the motor housing at the top of the lifting table leg into the installation space between the two beams, and then rotate the cam assembly so that the two beams press the motor housing in the installation space inwardly to complete the installation of the lifting table legs. The entire installation process does not require the use of any manual or electric tools, so that the assembly of the lifting table legs is simpler, more convenient and faster, meeting the user's needs for quick assembly. Furthermore, the locking mechanism composed of the cam assembly and the locking rod can press the crossbeam to the optimal pressing force that has been debugged during production, so the user can ensure the optimal installation accuracy of the lifting table legs during assembly.

[0022] In addition, the two support plates at both ends of the beam assembly can make the two connecting columns on the support plates be respectively hung in the hanging holes at the ends of the two beams when installing the lifting table legs; when the cam assembly is rotated to make the two beams move inward to press the motor housing in the installation space, the two hanging holes on the two beams simultaneously squeeze inward and lock the two connecting columns to complete the installation of the support plates; therefore, when the installation of the lifting table legs is completed, the two support plates under the table board for connecting the table board are also installed synchronously, thereby making the overall installation of the lifting table faster; similarly, the installation of the two support plates does not require the use of any manual or electric tools, thereby making the installation of the lifting table simpler and more convenient, and improving the installation efficiency of the lifting table.

DETAILED DESCRIPTION

[0035] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0036] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0037] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] See also Figures 1 to 9 As shown; the embodiment of the present application discloses a quick-install lifting table, whose structure includes a table top 1, a beam assembly 2 and a lifting table leg 3. Specifically in this embodiment, there are two lifting table legs 3 and they are respectively connected at the two ends of the beam assembly 2. Each lifting table leg 3 includes a table leg body 300 and a motor housing 301 connected to the top of the table leg body 300. A driving motor is connected in the motor housing 301. The table leg body 300 is a retractable table leg body 300 composed of a plurality of pipe fittings nested in each other. A linear driving mechanism is connected in the table leg body 300, and the input end of the linear driving mechanism is transmission-connected to the output end of the driving motor; the linear driving mechanism of this embodiment is a product component of the mature technology of the prior art, which is also called a screw nut pair; the extension and retraction of the linear driving mechanism can drive the expansion or contraction of the table leg body 300 pipe fittings, so under the drive of the driving motor, the table leg body 300 can be driven to extend and retract through the linear driving mechanism; in this embodiment, the lifting table is essentially an electric lifting table with dual motors, which also includes a base (not shown in the figure), which is connected to the lower end of the table leg body 300.

[0040] In this embodiment, the motor housing 301 at the top of the lifting table leg 3 is connected to the beam assembly 2. Specifically, in this embodiment, in order to facilitate the connection between the motor housing 301 of the lifting table leg 3 and the beam assembly 2, no fasteners such as screws, bolts or bolts are used during the entire connection process, and no manual or electric tools are required; see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the beam assembly 2 includes two beams spaced apart in the horizontal direction: a first beam 200 and a second beam 201. The two beams can move relative to each other to make the spacing of the installation space 202 formed between the two beams adjustable; that is, in the present embodiment, the two beams are independent of each other and can move relative to each other to change the spacing therebetween; the motor housing 301 at the top end of the lifting table leg 3 is accommodated in the installation space 202 between the first beam 200 and the second beam 201.

[0041] Further in the present embodiment, the quick-install lifting table further comprises a locking mechanism 5. In the present embodiment, since there are two lifting table legs 3, two locking mechanisms 5 are also provided and are respectively provided corresponding to the two lifting table legs 3. Each locking mechanism 5 comprises a locking rod 500 and a rotatable cam assembly 501. The cam assembly 501 has an eccentric cam portion 502. One end of the locking rod 500 is connected to the first beam 200. The other end of the locking rod 500 passes through the second beam 201 and is connected to the cam assembly 501. The cam portion 502 abuts against the outer side wall of the second beam 201. It is not difficult to understand It is understood that when the cam assembly 501 is rotated, because the cam portion 502 is eccentrically arranged, when the cam portion 502 is rotated to abut and squeeze the outer side wall of the second cross beam 201, the cam assembly 501 drives the locking rod 500 to be pulled outward, thereby reducing the distance between the two cross beams; when the cam assembly 501 is rotated in the opposite direction, the low position of the cam assembly 501, that is, the low position side opposite to the cam portion 502, can abut against the outer side wall of the second cross beam 201, thereby loosening the locking rod 500 and increasing the distance between the two cross beams; therefore, when the cam assembly 501 is rotated to the locking position, see Figure 3 In the position shown, the cam portion 502 presses the second beam 201 inwardly, so that the two beams move toward each other to press the motor housing 301 in the installation space 202; when the cam assembly 501 rotates to the unlocking position, see Figure 4 In the position shown, the cam portion 502 releases the squeezing of the second crossbeam 201 , so that the two crossbeams release the motor housing 301 in the installation space 202 .

[0042] In the above embodiment, the locking rod 500 is a cylindrical rod, which is arranged in a horizontal direction perpendicular to the beam assembly 2. The locking rod 500 passes through the coaxial mounting holes on the first beam 200 and the second beam 201 in sequence transversely, and is connected to the outer side of the first beam 200 with a head 504. The outer diameter of the head 504 is larger than the aperture size of the mounting hole. Therefore, when the other end of the locking rod 500 is rotated and tightened by the cam assembly 501, the locking rod 500 can simultaneously drive the two beams to move inward at the same time.

[0043] Further in the above embodiment, the locking mechanism 5 is composed of a locking rod 500 and a cam assembly 501. The cam assembly 501 is rotated, and under the action of the locking rod 500, the cam portion 502 of the cam assembly 501 can press the second cross beam 201 inwardly, so that the two cross beams move toward each other to press the motor housing 301 in the installation space 202. When unlocking, it is only necessary to rotate the cam assembly 501 in the opposite direction, and the cam portion 502 releases the squeezing of the second cross beam 201, so that the two cross beams release the motor housing 301 in the installation space 202. 1; Therefore, when installing the lifting table legs 3 of the quick-install lifting table, it is only necessary to insert the motor housings 301 at the top of the two lifting table legs 3 into the installation space 202 between the two beams, and then rotate the two cam assemblies 501 in turn, so that the two beams press the motor housings 301 in the installation space 202 inward to complete the installation of the two lifting table legs 3. The entire installation process does not require the use of any manual or electric tools, so that the assembly of the lifting table legs 3 is simpler, more convenient and faster, meeting the user's needs for quick assembly. Furthermore, the locking mechanism 5 composed of the cam assembly 501 and the locking rod 500 has the best pressing force that has been debugged during production to press the beams, so the user can ensure the best installation accuracy of the lifting table legs 3 during assembly.

[0044] Further in this embodiment, the quick-install lifting table also includes two support plates 4, which are bent into an L-shape as a whole and include a horizontal portion and a vertical portion, and the horizontal portion is covered on the top of the end of the beam assembly 2; see Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, two support plates 4 are respectively arranged at the two ends of the crossbeam assembly 2, and the two support plates 4 are used to be fixedly connected to the bottom of the table board 1, and two connecting columns 400 are connected to the horizontal part of each support plate 4. Both connecting columns 400 extend downward to the bottom of the horizontal part of the support plate 4; the two crossbeams at the end of the crossbeam assembly 2 are respectively provided with hanging holes 204 corresponding to the two connecting columns 400. When the cam assembly 501 rotates to the locking position, the two crossbeams move toward each other so that the two hanging holes 204 press inward and lock the two connecting columns 400, so that the support plate 4 is fixedly connected to the end of the crossbeam assembly 2. When the user is installing the lifting table legs 3, the two connecting columns 400 on the support plate 4 can be respectively hung in the hanging holes 204 at the ends of the two beams; when the cam assembly 501 is rotated to make the two beams move inward to press the motor housing 301 in the installation space 202, the two hanging holes 204 on the two beams simultaneously squeeze and lock the two connecting columns 400 inward to complete the installation of the support plate 4; therefore, when the installation of the lifting table legs 3 is completed, the two support plates 4 under the table board 1 for connecting the table board 1 are also installed synchronously, thereby making the overall installation of the lifting table faster; similarly, the installation of the two support plates 4 does not require the use of any manual or electric tools, thereby making the installation of the lifting table simpler and more convenient, and improving the installation efficiency of the lifting table.

[0045] In the above embodiment, in order to facilitate the positioning and assembly of the support plate 4. Figure 7 and Figure 8 As shown, a slot 205 extending along the length direction of the beam and penetrating the end surface of the beam at the outer end is provided at the end of the beam, and the width of the slot 205 is greater than the outer diameter of the connecting column 400; the hanging hole 204 is provided on the side wall of the slot 205 away from the center of the beam assembly 2. When assembling the support plate 4, first align the two connecting columns 400 on the support plate 4 with the two slots 205 at the ends of the two beams, and then press the support plate 4 toward the beam assembly 2, so that the connecting column 400 on the support plate 4 can enter the hanging hole 204 through the slot 205, thereby making the assembly of the support plate 4 easier.

[0046] It is not difficult to understand that in this embodiment, the hanging hole 204 is arranged on the side wall of the slot 205 away from the center of the beam assembly 2. Therefore, after the two beams move toward each other to make the two hanging holes 204 lock the connecting column 400, the connecting column 400 and the support plate 4 are limited on the beam assembly 2, and can effectively prevent the support plate 4 from detaching from the beam assembly 2.

[0047] Further, the connecting column 400 can be a connecting rod connected to the support plate 4 and having a column head at the free end to prevent it from being separated from the hanging hole 204. In this embodiment, see Fig. 9As shown, the connecting column 400 includes a first connecting member 401 vertically connected to the support plate 4 and a second connecting member 402 threadedly connected to the first connecting member 401, the lower end of the second connecting member 402 is provided with an anti-slip column head 403 whose outer diameter is larger than the diameter of the hanging hole 204, and the outer side wall of the second connecting member 402 is set as a tapered surface 404 with a small top and a large bottom; a hanging portion for the hanging hole 204 of the beam to be hung is formed between the anti-slip column head 403 and the support plate 4. When the hanging hole 204 of the beam is hung on the second connecting member 402 between the anti-slip column head 403 and the support plate 4, because the outer side wall of the second connecting member 402 is set as a tapered surface 404 with a small top and a large bottom, when the two beams move toward each other, the top of the beam and the horizontal part of the support plate 4 are pressed more and more tightly, so that the connection between the support plate 4 and the beam is more stable and firm.

[0048] In this embodiment, in order to make the motor housing 301 at the top of the lifting table leg 3 more accurately positioned in the installation space 202, further improve the convenience of connecting the lifting table leg 3, and make the motor housing 301 in the installation space 202 locked more firmly and stably; see Figure 6 and Figure 7 As shown, the locking mechanism 5 has two locking rods 500, and the two locking rods 500 are respectively connected to the cam assembly 501; specifically, a main shaft 505 is connected inside the cam assembly 501, and the main shaft 505 is respectively connected to the two locking rods 500, so that the two locking rods 500 can be locked or unlocked synchronously. The motor housing 301 is provided with two groups of card slots 303 that are respectively matched with the two locking rods 500 for positioning. When the motor housing 301 is accommodated in the installation space 202, the two groups of card slots 303 are respectively connected to the two locking rods 500, so that the position positioning of the motor housing 301 in the installation space 202 is more convenient and accurate, and the provision of the two locking rods 500 makes the locking of the motor housing 301 in the installation space 202 more stable. Therefore, when assembling the lifting table leg 3, the user only needs to make the two groups of slots 303 of the motor housing 301 correspondingly connected to the two locking rods 500, so that the positioning of the motor housing 301 in the installation space 202 is more convenient.

[0049] In the above embodiment, the two opposite side walls of the motor housing 301 are connected with the clamping plates 302 by screws, and the two sets of clamping slots 303 are respectively arranged on the two clamping plates 302, and the openings of the clamping slots 303 are arranged upward. The arrangement of the clamping plates 302 can not only protect the motor housing 301 from being squeezed by the crossbeam and deformed or damaged, but also the vertical arrangement of the clamping slots 303 on the clamping plates 302 also facilitates the user to clamp the clamping slots 303 on the clamping plates 302 on the locking rod 500.

[0050] It is not difficult to understand that when the table top 1 bears a large load or the load center of the table top 1 is deviated from the center of the table top 1 for a long time, or when it is subjected to an unexpectedly large pressure, the lifting table leg 3 may rotate relative to the crossbeam assembly 2, resulting in different heights of the two lifting table legs 3 of the lifting table; or, when the lifting table leg 3 is pre-connected with the crossbeam assembly 2, because the locking mechanism 5 is in a semi-locked state, if the force is uneven or the lifting table leg 3 is accidentally touched, it is easy to cause the lifting table leg 3 to rotate relative to the crossbeam assembly 2, causing the lifting table leg 3 to tilt. For this reason, in this embodiment, a first positioning structure is provided on the inner side walls of the two crossbeams of the installation space 202, and a second positioning structure is provided on the clamping plates 302 on both sides of the motor housing 301. The first positioning structure and the second positioning structure are matched and plugged in to limit the rotation of the table leg relative to the crossbeam assembly 2. This arrangement not only makes the connection between the lifting table leg 3 and the crossbeam assembly 2 more stable and firm, but also effectively prevents the table leg from rotating and tilting.

[0051] For example, see Figure 6 and Figure 7 As shown, the first positioning structure is a plurality of sockets 203 arranged on the inner walls of the two beams. Specifically, three sockets 203 are sequentially arranged on the inner wall of the first beam 200 and the inner wall of the second beam 201 along the length direction; the second positioning structure is a plug-in column 304 arranged on the clamping plate 302 and matched with the sockets 203. Specifically, three plug-in columns 304 corresponding to the sockets 203 are respectively arranged on the clamping plates 302 on both sides of the motor housing 301. When the cam assembly 501 is rotated to the locking position, the plug-in columns 304 are plugged into the sockets 203 on the beams in a one-to-one correspondence.

[0052] In other embodiments, the first positioning structure and the second positioning structure may also be toothed engaging structures, etc.; or the first positioning structure is a protrusion arranged on the inner side wall of the beam and extending along the length direction of the beam, and the second positioning structure is a groove adapted to be snapped therewith.

[0053] In some embodiments, see Figure 3 and Figure 4As shown, in order to facilitate the rotation of the cam assembly 501 and make the rotation of the cam assembly 501 more labor-saving, a handle portion 503 for driving the cam assembly 501 to rotate is provided on the cam assembly 501. In addition, a limiting plane 506 is provided on the handle portion 503 for abutting against the bottom plane of the beam assembly 2 when the cam assembly 501 rotates to the locking position, and is used to make up the gap between the locking rod 500 and the beam. The handle portion 503 extends outward in an inclined straight plate shape, and can abut against the bottom plane of the beam assembly 2 when in the locking position. It is not difficult to understand that the locking rod 500 is inserted into the mounting hole of the beam, and there is a certain gap between the locking rod 500 and the inner wall of the mounting hole of the beam, and when the cam assembly 501 rotates downward to the locking position, it is inevitable to drive the locking rod 500 to deflect downward by a certain angle. If the lifting table leg 3 is subjected to a large force, the locking rod 500 will move upward to the mounting hole, causing the lifting table leg 3 to be uneven and shake. In the present embodiment, the limiting plane 506 of the handle portion 503 is limited against the bottom plane of the beam assembly 2 when the handle portion 503 is rotated to the locking position, thereby preventing the locking rod 500 from moving upwards to the mounting hole, thereby compensating for the gap error between the locking rod 500 and the mounting hole; furthermore, in other words, the load-bearing capacity of the lifting table can be improved.

[0054] In some embodiments, see Fig.10 As shown, in order to prevent the cam assembly 501 from accidentally rotating and opening, a buckle 507 is connected to the handle portion 503 of the cam assembly 501, and a buckle head 508 is provided at the free end of the buckle 507; when the cam assembly 501 rotates to the locking position, the buckle 507 is located below the beam assembly 2 and the buckle head is buckled on the first beam 201. When the locking mechanism 5 is in the locking state, the buckle 507 spans the beam assembly 2 along the width direction of the beam assembly 2, and the buckle head 508 at the free end is buckled with the outer side wall of the first beam 201, which not only ensures the locking stability of the cam assembly 501, but also makes the clamping of the two beams more firm and stable.
