Description

Technical Field

[0001] The utility model relates to the technical field of furniture equipment, in particular to a lifting table and a cable guiding device of the lifting table. Background Art

[0002] The electric lift table is a common facility in daily applications. Because it can adjust the height and prevent myopia and various occupational diseases, it is usually used as a student desk, office furniture, etc. Its main working principle is that the electric operation drives the screw mechanism to rise and fall. The motor provides power by connecting to the power cord. Because the lift table drives the power cord to move when it is raised or lowered, the power cord cannot be well stored, resulting in a messy power cord, which not only affects the overall appearance, but the power cord is also prone to scratches, causing power outages and even rupture of the insulation layer of the power cord, posing a safety hazard. Utility Model Content

[0003] The purpose to be achieved by the utility model is to provide a lifting table and a cable guiding device of the lifting table, so as to solve the problem that the cables are messy and easily damaged by external force.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: the cable guiding device of the lifting table comprises:

[0005] a first guide arm for guiding the cable;

[0006] a second guide arm for guiding the cable;

[0007] The connecting unit comprises a first connecting body, a second connecting body and an elastic body, wherein the first connecting body is connected to the first guiding arm, the second connecting body is connected to the second guiding arm, the first guiding arm and the second guiding arm are pivotally connected through the connecting unit, and rotate and open with the lifting and lowering movement of the lifting table, and the elastic body is set in a compressed pre-tightened state so that it can tension the cable guiding device in the lifting direction of the lifting table;

[0008] The first connecting body, the second connecting body and the elastic body are constructed as an integrated structure.

[0009] After adopting the above technical scheme, the utility model has the following advantages: the first guide arm, the second guide arm and the connecting unit together form a cable guide device, which can store and organize the cables of the lifting table, and solve the problem of messy cable placement; and the first connector in the connecting unit is connected to the first guide arm, and the second connector is connected to the second guide arm. When the lifting table is lifted or lowered, the elastic body integrally constructed with the first connector and the second connector always tensions the cable guide device in the lifting direction of the lifting table because it is set in a compressed pre-tightened state, and the first guide arm and the second guide arm in the tensioned state are connected to each other at the connection position with the lifting table. The cable guide device is tightly pressed against the connecting unit, and it is difficult to deflect it in the lateral direction by external force, thereby improving the stability of the entire cable guiding device; when the entire cable guiding device is hit by external force, due to the presence of the elastomer in the connecting unit, the external force can be absorbed by its elasticity, and the structure of the cable guiding device is not easily damaged; when the lifting table significantly lowers the height of the desktop, compared with the rigid structure design in the prior art, the connecting part of the first guide arm and the second guide arm in the present design can absorb the external force received by the first guide arm and the second guide arm due to the presence of the elastomer, thereby avoiding excessive bending of the connection between the first guide arm and the second guide arm to cause damage to the cable.

[0010] Furthermore, the connection unit includes:

[0011] A first sheet-like body defining the first connector;

[0012] a second sheet-like body defining the second connector;

[0013] A third sheet-like body is defined for the elastic body, the third sheet-like body is compressed to present a curved structure, and connects the first sheet-like body and the second sheet-like body at an angle.

[0014] By adopting the aforementioned technical solution, the elastic body is set as a third sheet body that is compressed and presents a bent structure. When the height of the lifting table changes, the third sheet body can adjust the connection angle of the first guide arm and the second guide arm by bending. Since the sheet structure is more easily deformed in the bending direction, it can be better bent as the lifting table is lowered, ensuring that the first guide arm and the second guide arm will not interfere with the height adjustment of the lifting table; since the elastic body is the third sheet body, the sheet structure of the third sheet body also has a certain deformation range in the lateral direction. During installation, the installation accuracy of the first guide arm and the second guide arm can be reduced, and there is no need to keep the first guide arm aligned with the second guide arm, allowing The installation error is within a certain range, or the first guide arm and the second guide arm are installed obliquely; and when the height of the lifting table changes, if the first guide arm and the second guide arm are offset laterally during this change, the presence of the third sheet body can reduce the damage to the third sheet body caused by the lateral offset of the first guide arm and the second guide arm, and because the sheet structure also has the function of automatically correcting the lateral offset, the third sheet body can also bring the first guide arm and the second guide arm back to their original horizontal positions; wherein, the first connector and the second connector are sheet structures, which can be conveniently integrated with the third sheet body, and the sheet structure can reduce the overall weight of the design to achieve a lightweight design.

[0015] Furthermore, a groove is provided on the inner surface of the third sheet-shaped body, and the groove extends in the direction of the pivot axis defined by the connecting unit, and the groove contracts or expands with the elastic deformation of the third sheet-shaped body.

[0016] By adopting the above-mentioned technical solution, the groove design on the inner surface of the third sheet body can increase the strength of the third sheet body, making it less likely to break due to bending, and allowing the third sheet body to obtain more deformation space while having higher strength and a larger bending angle. When the lifting table is adjusted to a low height, it will not cause interference.

[0017] Furthermore, the first sheet-shaped body and the second sheet-shaped body both extend straight.

[0018] By adopting the above-mentioned technical solution, a better elastic utilization rate of the third sheet body can be obtained by a straight extension compared with a first sheet body and a second sheet body that are curved and extended, so that the rebound force of the third sheet body is better reflected on the first sheet body and the second sheet body, so that the first guide arm and the second guide arm can better press against the lifting table.

[0019] Further, the first sheet-shaped body and the first guiding arm are constructed as an integral structure and / or the second sheet-shaped body and the second guiding arm are constructed as an integral structure.

[0020] By adopting the above-mentioned technical solution, the integrated structure can have better strength and durability because there are no joints between components, which can reduce performance degradation and reliability problems caused by loose or damaged connections, thereby improving the overall strength and service life.

[0021] Further, the connecting unit is configured as a torsion spring, and the torsion spring comprises:

[0022] defining a first torsion spring arm of the first connector;

[0023] defining a second torsion spring arm of the second connector;

[0024] A spiral body connected between the first torsion spring arm and the second torsion spring arm defines the elastic body.

[0025] By adopting the above-mentioned technical solution, the torsion spring has good elastic recovery after being subjected to force, and can quickly return to its original state after releasing the torsional force. The response speed of the first guide arm and the second guide arm when the height of the lifting table is repeatedly adjusted can be improved, and the torsion spring has high adjustability. The elastic coefficient and energy storage capacity of the torsion spring can be adjusted by increasing the number of windings of the middle spiral body to cope with different models of lifting tables.

[0026] Furthermore, the connection unit is configured as a double torsion spring formed by two torsion springs connected in series.

[0027] By adopting the above-mentioned technical solution, the double torsion springs connected in series can make the movement of the first guide arm and the second guide arm more stable compared to a single torsion spring as a connecting unit, and will not deviate excessively to the left or right when moving up or down.

[0028] Furthermore, the first guide arm is connected to the outer side of the first connecting body, the second guide arm is connected to the outer side of the second connecting body, the first connecting body and the second connecting body are clamped between the first guiding arm and the second guiding arm and are pressurized by both to cause the elastic body to produce elastic deformation.

[0029] By adopting the above-mentioned technical solution, the elastomer integrally formed with the first connector and the second connector can undergo elastic deformation and become bent when the first connector and the second connector are pressurized by the first guide arm and the second guide arm to absorb the pressure from the first guide arm and the second guide arm, so as to protect the cable from being damaged due to bending.

[0030] Furthermore, the first connector, the second connector and the elastic body enclose a wiring space to allow the cable to bend and transition from the first guide arm to the second guide arm in a manner that follows the opening and closing of the connecting unit.

[0031] By adopting the above-mentioned technical solution, the wiring space allows the cable to bend along the first guide arm and transition to the second guide arm. The transition is smooth without any corners, and the cable will not be damaged due to bending, thereby extending the service life of the cable.

[0032] Furthermore, the first connecting body and the second connecting body can respectively pull the elastic body to generate lateral elastic deformation, so as to compensate for the lateral misalignment of the first guiding arm and the second guiding arm.

[0033] By adopting the above-mentioned technical solution, the first connector and the second connector can respectively pull the elastic body to produce lateral elastic deformation, so that workers can allow installation errors when installing the first guide arm and the second guide arm, thereby reducing installation accuracy and improving installation efficiency.

[0034] Furthermore, the first guiding arm and / or the second guiding arm has a routing cavity for guiding cables.

[0035] By adopting the above-mentioned technical solution, the wiring cavity can guide the cables to run along the first guide arm and / or the second guide arm, which is convenient for cable management and makes the entire cable guiding device more beautiful. At the same time, the wiring cavity can protect the cables to a certain extent and prevent the cables from being squeezed and causing cable failure.

When the lifting table is lifted or lowered, the elastic body integrally constructed with the first connecting body and the second connecting body can utilize its elastic properties to always tension the cable guiding device in the lifting direction of the lifting table because it is arranged in a compressed pre-tightened state. The first guiding arm and the second guiding arm in the tensioned state are pressed against the lifting table, thereby improving the stability of the entire cable guiding device; when the entire cable guiding device is collided with external force, due to the presence of the elastic body in the connecting unit, the external force can be absorbed by its elasticity, and the structure of the cable guiding device is not easily damaged; when the lifting table significantly lowers the height of the desktop, compared with the rigid structure design in the prior art, the connecting part of the first guiding arm and the second guiding arm in this design can absorb the external force received by the first guiding arm and the second guiding arm due to the presence of the elastic body, thereby avoiding excessive bending of the connection between the first guiding arm and the second guiding arm to cause damage to the cable.

Users can adjust the height of the frame according to their own needs; at the same time, the connecting plate fixed to the two lower columns or the two table legs can be used to place items, thereby increasing the storage space for the entire lifting table.

[0040] Furthermore, the electric table frame is provided with an upper mounting position and a lower mounting position for connecting the cable guiding device, the upper mounting position is arranged on the frame, and the lower mounting position is arranged on the side wall of the lower column or on the connecting plate.

[0042] Furthermore, an upper bracket is fixed on the upper mounting position, and the first guide arm or the second guide arm located at the top is hinged to the upper bracket; and / or, a lower bracket is fixed on the lower mounting position, and the first guide arm or the second guide arm located at the bottom is hinged to the lower bracket.

The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0068] Embodiment 1:

[0069] like Figures 1 to 3As shown, the utility model provides a cable guiding device for a lifting table, comprising:

[0070] A first guiding arm 1 for guiding the cable;

[0071] A second guiding arm 2 for guiding the cable;

[0072] The connecting unit includes a first connecting body 3, a second connecting body 4 and an elastic body 5. The first connecting body 3 is connected to the first guiding arm 1, and the second connecting body 4 is connected to the second guiding arm 2. The first guiding arm 1 and the second guiding arm 2 are pivotally connected through the connecting unit and rotate and open and close with the lifting movement of the lifting table. The elastic body 5 is set in a compressed pre-tightened state so that it can tension the cable guiding device in the lifting direction of the lifting table.

[0073] The first connecting body 3, the second connecting body 4 and the elastic body 5 are constructed as an integral structure.

[0074] The utility model comprises a first guide arm 1, a second guide arm 2 and a connecting unit to form a cable guide device, which can store and organize the cables of the lifting table and solve the problem of messy cable placement; and the first connector 3 in the connecting unit is connected to the first guide arm 1, and the second connector 4 is connected to the second guide arm 2. When the lifting table is lifted or lowered, the elastic body 5 integrally constructed with the first connector 3 and the second connector 4 always tensions the cable guide device in the lifting direction of the lifting table because it is arranged in a compressed pre-tightened state. The first guide arm 1 and the second guide arm 2 in the tensioned state are pressed against each other at the connection position with the lifting table, making it difficult to pass through External force causes it to deflect in the lateral direction, thus improving the stability of the entire cable guide device; when the entire cable guide device is hit by external force, due to the presence of the elastic body 5 in the connection unit, the external force can be absorbed by its elasticity, and the structure of the cable guide device is not easily damaged; when the lifting table is greatly reduced in height, compared with the rigid structure design in the prior art, the connection part of the first guide arm 1 and the second guide arm 2 in this design can absorb the external force received by the first guide arm 1 and the second guide arm 2 due to the presence of the elastic body 5, thus avoiding the situation where the connection between the first guide arm 1 and the second guide arm 2 is excessively bent and the angle is folded, causing damage to the cable. Of course, the elastic body 5 can be rubber, a thin flexible metal sheet, a flexible plastic such as TPE, TPU, etc., and the steering of the cable guide device is achieved through elastic deformation.

[0075] In another embodiment, the elastic body 5 in the connection unit has a preset bending direction opposite to that of the elastic body 5 in the above-mentioned solution, so that the elastic body 5 maintains a pre-opened state during the lifting process of the lifting table.

[0076] Specifically, in this embodiment, the connecting unit includes: a first sheet body 31 that defines a first connecting body 3; a second sheet body 41 that defines a second connecting body 4; and a third sheet body 51 that defines an elastic body 5, wherein the third sheet body 51 is compressed to present a curved structure, and connects the first sheet body 31 and the second sheet body 41 at an angle, wherein a threaded hole is provided on one end of the first sheet body 31 and the second sheet body 41 that is not connected to the third sheet body 51, and correspondingly, the first guide arm 1 and the second guide arm 2 connected thereto are provided with the same threaded hole, and the two are connected by bolts. The elastic body 5 is set to be a third sheet-like body 51 which is compressed and presents a curved structure. When the height of the lifting table changes, the third sheet-like body 51 can adjust the connection angle of the first guide arm 1 and the second guide arm 2 by bending. Since the sheet-like structure is more easily deformed in the bending direction, it can be better bent as the lifting table is lowered, ensuring that the first guide arm 1 and the second guide arm 2 will not interfere with the height adjustment of the lifting table; since the elastic body 5 is the third sheet-like body 51, the sheet-like structure of the third sheet-like body 51 also has a certain deformation range in the lateral direction. During installation, the installation accuracy of the first guide arm 1 and the second guide arm 2 can be reduced, and the first guide arm 1 does not need to be aligned with the second guide arm 2, allowing installation errors within a certain range, or the first guide arm 1 and the second guide arm 2 can be installed obliquely, such as Figure 1 The first guide arm 1 is installed on the rear side of the table top 20, and the second guide arm 2 is installed on the table leg 12, and the table leg 12 is located in the middle of the table top 20. Therefore, the positions of the first guide arm 1 and the second guide arm 2 are not corresponding to each other, but are installed obliquely; and when the height of the lifting table changes, if the first guide arm 1 and the second guide arm 2 are offset in the lateral direction during this change, the existence of the third sheet 51 can reduce the damage to the third sheet 51 caused by the lateral offset of the first guide arm 1 and the second guide arm 2, and because the sheet structure also has the function of automatically correcting the lateral offset, the third sheet 51 can also bring the first guide arm 1 and the second guide arm 2 back to the original horizontal position; wherein, the first connecting body 3 and the second connecting body 4 are sheet structures, which can be conveniently integrated with the third sheet 51, and the sheet structure can reduce the overall weight of the design to achieve a lightweight design. Of course, the first guide arm 1 and the first sheet 31, the second guide arm 2 and the second sheet 41 can also be connected by welding, riveting, etc.

[0077] In one embodiment, the first sheet 31 and the first guide arm 1 are constructed as an integral structure, and the integral structure can have better strength and durability, because there is no joint between components, which can reduce the performance degradation and reliability problems caused by loose or damaged connections, and improve the overall strength and service life. Of course, in another embodiment, the second sheet 41 and the second guide arm 2 are constructed as an integral structure.

[0078] Or as another alternative to the above solution, the first sheet 31 and the first guide arm 1, the second sheet 41 and the second guide arm 2 are constructed as an integral structure; the entire structure has no joints, and has better form performance and higher reliability than the connection structure.

[0079] Among them, Figure 3 As shown, in this embodiment, the inner surface of the third sheet 51 is provided with a plurality of transverse grooves 6, the grooves 6 extending in the direction of the pivot axis defined by the connection unit, and the grooves 6 shrink or stretch with the elastic deformation of the third sheet 51. The structure of the grooves 6 designed on the inner surface of the third sheet 51 can increase the strength of the third sheet 51, making it less likely to break due to bending, and allowing the third sheet 51 to have more deformation space while having higher strength, and having a larger bending angle, so that the lifting table will not cause interference when it is adjusted to a low height.

[0080] In one embodiment, the inner surface of the third sheet body 51 may not be provided with the groove 6, and its strength can be enhanced by increasing the thickness of the sheet body; the inner surface of the third sheet body 51 may also be provided with a groove for guiding the routing of the cable, so that the cable can smoothly transition from the first guide arm 1 to the second guide arm 2 following the groove.

[0081] Specifically, the first sheet 31 and the second sheet 41 both extend straight; compared with the first sheet 31 and the second sheet 41 extending in a curved manner, the straight extension can obtain better elastic utilization of the third sheet 51, so that the rebound force of the third sheet 51 is better reflected on the first sheet 31 and the second sheet 41, so that the first guide arm 1 and the second guide arm 2 can better press against the lifting table.

[0082] Specifically, in this embodiment, the first guide arm 1 is connected to the outer side of the first connecting body 3, the second guide arm 2 is connected to the outer side of the second connecting body 4, the first connecting body 3 and the second connecting body 4 are clamped between the first guiding arm 1 and the second guiding arm 2 and are pressurized by the two to cause the elastomer 5 to undergo elastic deformation; the elastomer 5 integrally formed with the first connecting body 3 and the second connecting body 4 can undergo elastic deformation and become bent when the first connecting body 3 and the second connecting body 4 are pressurized by the first guiding arm 1 and the second guiding arm 2 to absorb the pressure from the first guiding arm 1 and the second guiding arm 2, so as to protect the cable from being damaged due to bending.

[0083] Of course, in another embodiment, the first guiding arm 1 may also be connected to the inner side of the first connecting body 3 , and the second guiding arm 2 may be connected to the inner side of the second connecting body 4 .

[0084] Among them, in this embodiment, the first guide arm 1 and the second guide arm 2 have a routing cavity 7 for guiding the cable; taking the first guide arm 1 as an example, the routing cavity 7 is specifically a slot on the first guide arm 1, and the routing cavity 7 can guide the cable to be routed along the first guide arm 1 and the second guide arm 2, which is convenient for the cable to be collected and makes the entire cable guiding device more beautiful. At the same time, the routing cavity 7 can play a certain protective role on the cable to prevent the cable from being squeezed and causing the cable to fail. Of course, in another embodiment, taking the first guide arm 1 as an example, the routing cavity 7 can also be a through hole that axially penetrates the entire first guide arm 1.

[0085] As a simple replacement for the above solution, the first guide arm 1 has a routing cavity 7 for guiding the cable; the routing cavity 7 can guide the cable to be routed along the first guide arm 1;
