[0001] The present application relates to the technical field of furniture, in particular to a table. BACKGROUND

[0002] The working table is also called a learning table, a desk, etc. The structure thereof comprises a table board, a crossbeam assembly, a table leg and a base. The upper end of the table leg is connected with the crossbeam assembly, the lower end of the table leg is connected with the base, and the table board is installed on the top of the crossbeam assembly. In order to better meet the needs of users of different heights and different age groups, most of the existing working tables are set as lifting tables, that is, the height of the working table can be adjusted according to the height, sitting posture and standing posture of the person, so as to meet the pursuit of people for the healthy office mode.

[0003] In order to make the length of the crossbeam assembly adapt to the length of the table board of different sizes, and to facilitate the user to purchase and assemble, and to save the cost of transportation and packaging, the crossbeam assembly of the related art working table is set as a telescopic type. For example, the crossbeam assembly used in the lifting table of the prior application of the present application with the announcement number CN209711979U, CN210870326U or CN219306224U comprises two crossbeam bodies which can be relatively moved to adjust the length, a first crossbeam body and a second crossbeam body. A connecting seat is arranged at the bottom between the first crossbeam body and the second crossbeam body, and the connecting seat is detachably connected with the bottom of the first crossbeam body and the bottom of the second crossbeam body through screws. The length of the crossbeam assembly is adjusted by adjusting the fixed position of the first crossbeam body and the second crossbeam body in the length direction of the connecting seat. Alternatively, a connecting rod is arranged between the first crossbeam body and the second crossbeam body. One end of the connecting rod is arranged in the inner hole of the first crossbeam body, and the other end of the connecting rod is arranged in the inner hole of the second crossbeam body. After the spacing between the two crossbeam bodies is adjusted, the two ends of the connecting rod are locked on the two crossbeam bodies by the locking screws.

[0004] The crossbeam assembly of the above-mentioned related art working table generally has some deficiencies in the actual assembly process. After the length of the crossbeam assembly is adjusted, a plurality of screws are needed to fix the two crossbeam bodies and the connecting seat or the connecting rod between the two crossbeam bodies, and a hand tool or a power tool must be used to tighten and fix the screws. Moreover, due to the limited installation level of the user, the length of the crossbeam assembly cannot be adjusted at one time, and the length of the crossbeam assembly needs to be measured or corrected multiple times. Therefore, the length adjustment operation of the crossbeam assembly is relatively troublesome, time-consuming and laborious. In addition, the table leg and the support plate of the above-mentioned related art working table also need to be installed by using screws, so that the assembly efficiency of the whole working table is low, and the user experience is poor.

[0046] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Referring to FIGS. 1-4, the embodiment of the application discloses a crossbeam assembly which can be used in furniture such as worktable, lifting table or supporting platform, installed at the bottom of table board or table top, playing a supporting role. The crossbeam assembly comprises two crossbeam bodies: a first crossbeam body 200 and a second crossbeam body 201. Both the first crossbeam body 200 and the second crossbeam body 201 are long-shaped members, arranged in sequence along the length direction of the crossbeam assembly 2 and movable relative to each other to adjust the length of the crossbeam assembly 2. In this embodiment, both the crossbeam bodies are integrally formed by bending a metal plate, which has simple structure, light weight, convenient transportation and low cost.

[0048] In some embodiments, the crossbeam body can also be formed by welding two square metal tubes arranged in parallel.

[0049] In some embodiments, in order to facilitate the adjustment of the distance between the first crossbeam body 200 and the second crossbeam body 201, i.e. the length of the crossbeam assembly 2, a first joint surface 206 is arranged on the first crossbeam body 200 along the length direction, and a second joint surface 207 is arranged on the second crossbeam body 201 along the length direction. It is not difficult to understand that the first joint surface 206 and the second joint surface 207 are planes in the same horizontal plane, i.e. the outer surfaces of the two crossbeam bodies. A connecting plate 7 is arranged between the two crossbeam bodies, as shown in FIGS. 1 and 2. The connecting plate 7 is a long-shaped plate member arranged along the length direction of the crossbeam assembly 2. The bottom of the connecting plate 7 is also a plane and is in sliding fit with the first joint surface 206 and the second joint surface 207 respectively. That is, the bottom surface of the connecting plate 7 simultaneously fits and contacts the first joint surface 206 and the second joint surface 207 of the two crossbeam bodies, and the two crossbeam bodies are slidable relative to the connecting plate 7 along the length direction of the crossbeam assembly 2.

[0050] It is not difficult to understand that when the two crossbeam bodies move relative to the connecting plate 7 along the length direction of the crossbeam assembly 2 to adjust the length of the crossbeam assembly 2, uneven force may cause the connecting plate 7 to disengage or fall off, thereby affecting the length adjustment of the crossbeam assembly 2. In the present application, as shown in FIG. 2, the crossbeam assembly 2 further comprises two pressure wheel assemblies 8, which are connected to the two crossbeam bodies respectively, and the pressure wheels 801 of the two pressure wheel assemblies 8 are in pressure contact with the connecting plate 7, for generating a pre-tightening pressure of the connecting plate 7 on the first joint surface 206 and the second joint surface 207. The pre-tightening pressure is configured to press the connecting plate 7 against the first joint surface 206 and the second joint surface 207 respectively, and to enable any crossbeam body to slide along the length direction relative to the connecting plate 7 under the action of external force.

[0051] As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the top of each beam body is provided with a downwardly recessed accommodating groove 208 formed with an opening on the top of the beam body in the length direction. Specifically, the beam body of the present application is integrally formed by bending a metal plate, and thus the accommodating groove 208 is formed by bending the metal plate. The inner bottom wall of the accommodating groove 208 of each beam body forms a first joint surface 206 and a second joint surface 207, respectively. A connecting plate 7 is sleeved in the accommodating groove 208 of each beam body, and the bottom of the connecting plate 7 is attached to the first joint surface 206 and the second joint surface 207, respectively. Two pressing wheel assemblies 8 are connected to the top of the first beam body 200 and the second beam body 201, respectively, and the two pressing wheel assemblies 8 are located at the inner ends of the two beam bodies, respectively.

[0052] It can be understood that the pressing wheels 801 of the pressing wheel assemblies 8 are pressed against the connecting plate 7, and the connecting plate 7 is pre-tightened against the first joint surface 206 and the second joint surface 207. That is, when the pressing wheel assemblies 8 are installed, the pressing wheels 801 of the pressing wheel assemblies 8 are interference-fitted in the accommodating grooves 208 and abut against the side of the connecting plate 7 away from the joint surfaces, so that the first joint surface 206 and the connecting plate 7 and the second joint surface 207 and the connecting plate 7 have a large frictional force. The frictional force can ensure that the beam assembly 2 is fixed or locked in a natural state or a free state. If the pulling force applied to the first beam body 200 and / or the second beam body 201 is greater than the frictional force, the beam body can slide relative to the connecting plate 7.

[0053] In some embodiments, the crossbeam assembly comprises a connecting plate 7, two crossbeam bodies and two pressing wheel assemblies 8, the two pressing wheel assemblies 8 are connected to the two crossbeam bodies respectively, and the pressing wheels 801 of the two pressing wheel assemblies 8 are pressed against the connecting plate 7 respectively, so as to generate a pre-tightening pressure on the first and second joint surfaces 206 and 207 of the two crossbeam bodies, under the pre-tightening pressure, the connecting plate 7 is pressed against the first and second joint surfaces 206 and 207 respectively, so that the two crossbeam bodies are positionally fixed in a natural state, and when the user adjusts the length of the crossbeam assembly 2, only needs to exert an external force on any crossbeam body in the length direction of the crossbeam, so as to make the crossbeam body slide out or retract in the length direction relative to the connecting plate 7. Therefore, when the user adjusts the length of the crossbeam assembly 2, only needs to pull any crossbeam body outward or inward to adjust the distance between the two crossbeam bodies, so as to adjust the length of the crossbeam assembly 2. Furthermore, the pre-tightening pressure exerted by the pressing wheel assembly 8 on the connecting plate 7 generates a friction force between the connecting plate 7 and the first and second joint surfaces 206 and 207, so that the two crossbeam bodies and the connecting plate 7 are positionally fixed in a natural state under the action of the friction force. Therefore, when the length of the crossbeam assembly 2 is adjusted, any crossbeam body can be pulled out outward without using any manual or electric tool, only needs to overcome the friction force between the connecting plate 7 and the joint surfaces, the operation is simple, labor-saving and fast, saves the installation time of the table, and meets the needs of the user for rapid assembly.

[0054] The pressing wheel 801 in the present application can be made of an elastic material, such as rubber, and has a certain elastic deformation capacity when it is in interference fit with the connecting plate 7, so that the connecting plate 7 is pressed against the first and second joint surfaces 206 and 207 more tightly.

[0055] In some embodiments, as shown in FIGS. 2 and 4, under the premise of ensuring that the connecting plate 7 is pressed against the first and second joint surfaces 206 and 207, in order to make the length adjustment of the crossbeam assembly 2 more convenient and labor-saving, each pressing wheel assembly 8 comprises a bracket 800 connected to the crossbeam body, and at least one pressing wheel 801 is rotatably connected to the top plate of the bracket 800, and the axis of the pressing wheel 801 is perpendicular to the length direction of the connecting plate 7. The pressing wheel 801 can rotate automatically with the movement of the crossbeam body during the length adjustment of the crossbeam assembly 2, so as to facilitate the movement of the crossbeam body and make the operation more labor-saving.

[0056] In some embodiments, a telescopic rod with a compression spring can also be used to connect the rolling shaft of the pressing wheel and the top plate of the bracket, so that the connecting plate 7 is pressed against the first and second joint surfaces 206 and 207 more tightly.

[0057] For example, as shown in FIG. 2, FIG. 3 and FIG. 4, the bracket 800 of each compression wheel assembly 8 is rotatably connected with two compression wheels 801 distributed along the length direction of the connecting plate 7, and the axes of the two compression wheels 801 are parallel. The bracket 800 of the compression wheel assembly 8 is connected to the opening of the accommodating groove 208 of the beam body by screws, and the mounting end of the bracket 800 for mounting the compression wheel 801 extends downward into the accommodating groove 208, so that the compression wheel 801 mounted on the mounting end of the bracket 800 is in interference fit or compression fit with the connecting plate 7. In some embodiments, the number of compression wheels in the compression wheel assembly 8 can be adjusted according to actual needs, and the number of compression wheels in the two compression wheel assemblies 8 can be the same or different, that is, the bracket 800 of at least one compression wheel assembly 8 is rotatably connected with two or more compression wheels 801 distributed along the length direction of the connecting plate 7.

[0058] In some embodiments, at least one compression wheel assembly can include one or more groups of compression wheels distributed along the length direction of the connecting plate. Specifically, each group of compression wheels includes a plurality of coaxial and spaced narrow compression wheels, and the width of the narrow compression wheel is much smaller than the width of the beam assembly, so the beam assembly can accommodate a plurality of coaxial and spaced narrow compression wheels. Further, in order to improve the stability of the movement of the beam body relative to the connecting plate, a track adapted to the narrow compression wheel can also be provided on the connecting plate, wherein the track can be one or more.

[0059] In some embodiments, as shown in FIG. 2, the connecting plate 7 is also integrally bent and formed from a metal plate, and its shape is adapted to the shape of the accommodating groove 208 of the beam body, avoiding the displacement of the connecting plate 7 during the movement of the beam body; the two sides of the connecting plate 7 are respectively provided with side plates which are in sliding fit with the inner side walls of the two sides of the accommodating groove 208. In this way, the connecting plate 7 and the beam body are more compactly matched, and the friction between the connecting plate 7 and the beam body is further improved, realizing the self-locking of the positions of the two beam bodies in the natural state.

[0060] In some embodiments, as shown in FIG. 2, the two ends of the connecting plate 7 are respectively provided with anti-falling limiting parts 700 which abut against the bracket 800 to prevent the connecting plate 7 from falling off, and the anti-falling limiting part 700 is a protrusion formed on the connecting plate 7 and extending into the accommodating groove 208. Specifically, the end portions of the side plates on both sides of the connecting plate 7 are respectively provided with two protrusions which extend into the accommodating groove 208. When the beam body moves outward relative to the connecting plate to the limit position, the bracket 800 of the compression wheel assembly 8 on the beam body abuts against the protrusions on the end portions of the connecting plate 7 to prevent the connecting plate 7 from disengaging from the beam body, which is good in safety of use.

[0061] The application also discloses a table, which comprises a table board 1, a beam assembly 2, a support plate 5, a table leg 3 and a base 4, wherein the beam assembly 2 is the beam assembly of any one of the above embodiments. The table leg 3 is two and is connected at two ends of the beam assembly 2 respectively, and the lower end of the table leg 3 is connected with the base 4. The table can also be a common work table, i.e. a work table without lifting function; or can be an electric or manual lifting table with lifting function. The table adopts the beam assembly of the above embodiments, and when the length of the beam assembly is adjusted to be suitable for the table board 1, only one of the beam bodies is pulled out to a suitable position by force under the cooperation of the pressing wheel assembly 8 and the connecting plate 7. When the length of the beam assembly 2 is adjusted, any manual or electric tool is not needed, the operation is simple, labor-saving and fast, the installation time of the table is saved, and the assembly efficiency of the table is improved.

[0062] In some embodiments, the table of the application can be an electric lifting table, as shown in Figs. 5-12. The end of the first beam body 200 and the second beam body 201 of the beam assembly 2 of the table is provided with a mounting space 202 along the length direction, i.e. the beam assembly 2 comprises two horizontally parallel and spaced beam bodies, i.e. the first beam body 200 and the second beam body 201, and the mounting space 202 is formed between the side walls of the beam assembly. The top end of the table leg body 300 of the table leg 3 is connected with a motor housing 301, and the motor housing 301 is at least partially accommodated in the mounting space 202.

The support plate 5 is provided with a plug-in part 500 which is plugged into the end of the beam assembly 2, and the free end of the plug-in part 500 is plugged into the plug-in hole 303 of the motor housing 301. Specifically, as shown in Fig. 5, the motor housing 301 has a first end close to the support plate 5 and a second end away from the support plate 5. The two sides of the first end of the motor housing 301 are respectively connected with horizontally arranged baffles 302 which are limited by the bottom of the beam assembly 2 when the motor housing 301 is accommodated in the mounting space 202 of the beam assembly 2, and the plug-in hole 303 is arranged on each baffle 302 in the vertical direction. The motor housing 301 is connected with a driving motor. The table leg body 300 is a telescopic table leg body 300 composed of a plurality of pipe fittings which are nested with each other. A linear driving mechanism is connected in the table leg body 300, and the input end of the linear driving mechanism is in transmission connection with the output end of the driving motor. The table can comprise two support plates 5 which are respectively connected at the two ends of the beam assembly 2 and are connected with the bottom of the table board 1, for supporting the table board 1 and making the connection of the table board 1 more stable. In order to facilitate the connection of the motor housing 301 of the table leg 3, the support plate 5 and the beam assembly 2, no fasteners such as screws, nuts or bolts are used in the whole connection process, and no manual or electric tool is needed

[0063] The linear drive mechanism of the embodiment is a product component of mature technology in the prior art, which is also called a screw-nut pair; the extension and retraction of the linear drive mechanism can drive the expansion or contraction of the pipe of the table leg body 300, so that the table leg body 300 can be driven to extend and retract through the linear drive mechanism under the driving of the driving motor; in the embodiment, the table is essentially an electric lifting table with double motors.

[0064] Further, as shown in FIGS. 6 and 7, the support plate 5 is a metal plate bending piece, including an integrally bent horizontal portion and a vertical shielding portion, the horizontal portion is arranged on the top plane of the end portion of the cross beam assembly 2, and the shielding portion is used to shield the end portion of the cross beam assembly 2; two vertical downwardly arranged insertion plates corresponding to the end portions of the cross beam bodies of the cross beam assembly 2 are arranged in the middle of the support plate 5, and the two insertion plates form a support insertion part 500; similarly, the end portions of the cross beam assembly 2 are respectively provided with insertion slots 203 penetrating through the top wall and the bottom wall of the cross beam assembly 2 in the vertical direction; the two insertion plates of the insertion part 500 of the support plate 5 are respectively inserted into the two insertion slots 203 of the cross beam assembly 2, and the free ends of the two insertion plates extend downwardly beyond the bottom of the cross beam assembly 2 and are respectively inserted into the insertion holes 303 of the baffle plates 302 on the two sides of the motor housing 301.

[0065] It can be understood that, in order to facilitate the user to assemble the table by himself after purchase, the table top 1, the cross beam assembly 2, the support plate 5, the table leg 3 and the base 4 are independent components, that is, the table top 1, the cross beam assembly 2, the support plate 5, the table leg 3 and the base 4 form independent installation modules when the product is shipped, and each module itself does not need to be assembled by the user.

[0066] In some embodiments, the table further comprises a locking mechanism 6 mounted on the beam assembly 2, the locking mechanism 6 is connected to the beam assembly 2, and the locking mechanism 6 is detachably connected to the motor housing 301. The locking mechanism 6 comprises a handle part 601 rotatably connected to the beam assembly 2, and a traction part 600 rotatably connected to the handle part 601 and hung with the hanging part 304 of the motor housing 301. The locking mechanism 6 is used to drive the motor housing 301 to move away from the side of the support plate 5 and reach the locking position. When in the locking position, the locking mechanism 6 exerts a pressing force on the motor housing 301 and the plug-in part 500, so that the motor housing 301 is fixed in the mounting space 202 and the support plate 5 is fixed on the beam assembly 2. Therefore, when assembling the table, the motor housing 301 of the table leg 3 is first accommodated in the mounting space 202 of the beam assembly 2 from bottom to top, then the two plug-in plates of the plug-in part 500 of the support plate 5 are respectively plugged into the insertion slot 203 at the end of the beam assembly 2 and the free end of the plug-in part 500 is plugged into the plug-in hole 303 of the motor housing 301, and then the locking mechanism 6 is hung with the hanging part 304 of the motor housing 301. The locking mechanism 6 drives the motor housing 301 and the plug-in part 500 to move away from the support plate 5 along the length direction of the beam assembly 2, and the motor housing 301 reaches the locking position. The pressing force or traction force exerted by the locking mechanism 6 on the motor housing 301 and the plug-in part 500 simultaneously completes the fixation of the motor housing 301 and the support plate 5.

[0067] When the table legs 3 and the support plate 5 are installed, no manual or electric tools are needed, so that the assembly of the table legs 3 and the support plate 5 is more simple, convenient, fast and efficient, meeting the needs of users for quick assembly. Specifically, the use of the locking mechanism 6 completes the installation of the support plate 5 at the end of the beam assembly 2 while installing the table legs 3, so that the overall installation of the table is more efficient. Furthermore, the plug-in part 500 of the support plate 5 is inserted into the plug-in hole 303 of the motor housing 301, and the locking mechanism 6 simultaneously locks the plug-in part 500 and the motor housing 301. Therefore, when the table legs 3 and the support plate 5 are installed, no manual or electric tools are needed, so that the assembly of the table legs 3 and the support plate 5 is more simple, convenient, fast and efficient, meeting the needs of users for quick assembly. Furthermore, the locking mechanism 6 simultaneously locks the plug-in part 500 and the motor housing 301 on the beam assembly 2, which makes the locking force of the plug-in part 500 and the motor housing 301 the best locking or pressing force that has been debugged during production. Therefore, the user can ensure the best installation accuracy of the table legs 3 and the support plate 5 during assembly.

[0068] In order to avoid the disengagement of the insertion hole 303 of the motor housing 301 from the insertion part 500 of the support plate 5 when the locking mechanism 6 is locking the movement of the motor housing 301 away from the support plate 5, a clamping groove 501 is arranged at the free end of the insertion part 500, and the clamping groove 501 is clamped with the insertion hole 303 of the baffle 302 of the motor housing 301; that is, the free end of the two insertion plates of the insertion part 500 is respectively provided with a horizontal clamping groove 501 with an opening facing away from the locking mechanism 6, and the free end of the insertion part 500 is inserted into the insertion hole 303, and as the motor housing 301 is pulled by the locking mechanism 6, the clamping groove 501 is clamped on the insertion hole 303, thereby avoiding the disengagement of the two.

[0069] In some embodiments, the free end of the insertion part can also be provided with an L-shaped or hook-shaped structure, or a horizontal limiting protrusion is arranged at the free end of the insertion part to prevent the disengagement of the insertion part from the insertion hole.

[0070] Similarly, in order to avoid the deviation or inclination of the end of the motor housing 301 being pulled by the locking mechanism 6 when the locking mechanism 6 is locking the movement of the motor housing 301 away from the support plate 5, a top plate 204 is connected to the crossbeam assembly 2 at the top of the installation space 202, and the top plate 204 can abut against the top of the motor housing 301. It is not difficult to understand that the limiting effect of the top plate 204 on the top of the motor housing 301 and the limiting effect of the baffle 302 of the motor housing 301 on the bottom of the crossbeam assembly 2, so that when the locking mechanism 6 pulls the motor housing 301, the motor housing 301 can not be inclined, and the movement of the motor housing 301 in the installation space 202 of the crossbeam assembly 2 is a horizontal straight line.

[0071] The locking mechanism 6 and the motor housing 301 are detachably connected to drive the motor housing 301 to move away from the support plate 5 and reach the locking position. Referring to FIGS. 7 and 8, the locking mechanism 6 includes a pulling member 600 and a handle part 601 rotatably connected to the crossbeam assembly 2, one end of the pulling member 600 is detachably connected to the motor housing 301, that is, the one end of the pulling member 600 is hung on the hanging part 304 of the motor housing 301, and the other end of the pulling member 600 is rotatably connected to the handle part 601; the handle part 601 rotates around an axis to switch between the locking position and the release position, when the handle part 601 is driven to the locking position, the pulling member 600 drives the motor housing 301 to move to the locking position; when the handle part 601 is driven to the release position, the locking mechanism 6 releases the extrusion force applied to the motor housing 301 and the insertion part 500, and the pulling member 600 can be detached from the motor housing 301.

[0072] The locking position of the embodiment is the limit position of the motor housing 301 moving away from the support plate 5, at which position the motor housing 301 is kept locked under the extrusion or traction force of the locking mechanism 6, and the motor housing 301 applies the extrusion or traction force to the plug-in part 500 of the support plate 5 to keep the support plate 5 locked on the beam assembly 2.

[0073] It is not difficult to understand that the traction member 600 is rotatably connected with the handle part 601, i.e. the end of the traction member 600 is rotatably connected with the middle part of the handle part 601, when the handle part 601 is pulled in the direction away from the support plate 5, the handle part 601 forms a lever with its rotation center as the fulcrum, drives the traction member 600 to move away from the support plate 5, so that the locking of the locking mechanism 6 is more labor-saving. Moreover, in the embodiment, when the handle part 601 is driven to the locking position, the handle part 601 abuts against the bottom of the beam assembly 2 to limit; and the release position is that the handle part 601 is driven to the disengagement position in the direction close to the support plate 5.

[0074] In order to keep the handle part 601 of the locking mechanism 6 in the locking position without being accidentally opened or rotated to unlock, referring to FIG. 7 and FIG. 8, a guide hole 606 extending along the length direction is arranged on the beam assembly 2, a rotating shaft 602 is slidably connected in the guide hole 606, the handle part 601 is connected with the rotating shaft 602, and the handle part 601 can rotate around the circumferential direction of the rotating shaft 602; the locking mechanism 6 further comprises a resilient member 604, which can be a tension spring, in order to provide sufficient and symmetrical elastic force, the resilient member 604 can be specifically provided as two or more parallel arranged tension springs, one end of the two tension springs is connected with the rotating shaft 602, and the other end is connected with a positioning rod 605 in the beam assembly 2, for keeping the rotating shaft 602 always having a movement trend away from the support plate 5. That is, when the handle part 601 is rotated to the locking position, under the elastic force of the resilient member 604, the rotating shaft 602 always has a movement trend away from the support plate 5, the elastic force of the resilient member 604 is converted into the pulling force on the motor housing 301 through the handle part 601 and the traction member 600, so that the motor housing 301 is connected more firmly and stably at the locking position, and the support plate 5 is also combined more firmly with the end of the beam assembly 2. In addition, the elastic force of the resilient member 604 always applies the elastic force away from the support plate 5 to the handle part 601, avoiding the handle part 601 from rotating in the direction close to the support plate 5, so that the handle part 601 can stay or remain at the locking position, improving the safety of use. In addition, the sliding cooperation of the rotating shaft 602 and the guide hole 606, when the handle part 601 is rotated to unlock, the rotating shaft 602 of the handle part 601 moves in the direction close to the motor housing 301 to overcome the elastic force of the resilient member 604, so as to avoid the interference caused by the rotation of the traction member 600, and make the unlocking operation more labor-saving.

[0075] As shown in FIG. 7 and FIG. 8, the locking mechanism 6 is detachably connected with the motor housing 301, that is, one end of the traction member 600 is detachably connected with the motor housing 301. Specifically, the motor housing 301 is provided with a hanging part 304, and the traction member 600 is hung with the hanging part 304. The hanging part 304 is arranged at the second end of the motor housing 301, that is, the end of the motor housing 301 away from the support plate 5. The hanging part 304 on the motor housing 301 is a hook arranged at the second end of the motor housing 301, and the hook is two and is respectively located at the two sides of the second end of the motor housing 301. The traction member 600 has a hanging rod 603 matched with the two hooks for hanging. The hanging rod 603 is hung on the two hooks, and when the handle part 601 of the locking mechanism 6 is rotated to the locking position, the hanging rod 603 pulls the motor housing 301 to move and is locked through the hook. The hanging of the hanging rod 603 of the traction member 600 with the hook of the hanging part 304 makes the locking operation of the motor housing 301 more simple and convenient; and when the handle part 601 is rotated to the release position, the motor housing 301 is also convenient to be separated from the locking mechanism 6.

[0076] It is not difficult to understand that when the handle part 601 drives the motor housing 301 to move to the locking position, because the hanging rod 603 of the traction member 600 is hung with the hook of the hanging part 304, in order to keep the second end of the motor housing 301, that is, the hook end stable, avoid the hanging rod 603 swing in the height direction of the table leg 3, make the motor housing 301 connection unstable, as shown in FIG. 3 and FIG. 8, a limiting groove 205 extending along the length direction is arranged on the cross beam assembly 2, and the opening of the limiting groove 205 penetrates the bottom wall or the top wall of the cross beam assembly 2; when the handle part 601 is driven to the locking position, the hanging rod 603 is clamped in the limiting groove 205 through the opening. The limiting groove 205 plays a limiting role in the longitudinal or height direction of the hanging rod 603, so that the motor housing 301 is more stable and firm in connection.

[0077] In some embodiments, the detachable structure of the second end of the motor housing and the traction member can also be arranged as connecting a rod member at the second end of the motor housing, and replacing the hanging rod of the traction member with two hooks or clamping grooves, which is also convenient for the detachable connection of the two.

[0078] In some embodiments, the locking mechanism can also adopt the following ways, such as cam rotation locking, that is, a cam is rotationally connected on the cross beam assembly, the cam is connected with the second end of the motor housing through a pull rod, the cam is rotated away from the support plate to generate a traction force, so that the motor housing moves to the locking position, and similarly, the cam is rotated to approach the support plate to eliminate the traction force to release the motor housing. Or through the pull rod with spring, that is, one end of the pull rod is connected with the second end of the motor housing, the other end of the pull rod is connected with the spring, the spring is connected with the cross beam assembly, and the spring force is used to make the motor housing move to the locking position and be fixed.

[0079] In some embodiments, for example, the table does not include a motor, or the table includes a motor only in a single table leg, or the table includes a motor in each table leg, the locking mechanism can also be detachably connected with the table leg body, that is, the insertion hole and the hanging part are arranged on the table leg body.
