DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 2 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0021] Figure 1 This is a structural diagram of an embodiment of a lifting table with a wire handle of the present invention; Figure 2 FIG. 1 is a structural diagram of a handle of a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, the lifting table with a wire handle provided in this embodiment includes: a base frame 1, table legs 2, a desktop 3, a working cylinder and a handle 5. At this time, the table legs 2 are installed on the base frame 1, the desktop 3 is installed on the table legs 2, and the working cylinder is installed between the table legs 2 and the desktop 3 or between the table legs 2 and the base frame 1. The desktop 3 is driven to rise and fall relative to the table legs 2 by the working cylinder, and the working cylinder has a control switch, and the control switch is connected to a steel wire 4. The control switch is pulled by the steel wire 4 to control the movement of the working cylinder, thereby meeting the lifting and lowering control requirements of the desktop 3. It is worth pointing out that the table legs 2 can be a scissor-type structure or a telescopic structure. There are many related structures on the market, and they can meet the lifting requirements. Therefore, its specific structure and the connection structure between the base frame 1 and the desktop 3 will not be repeated here.

[0022] Specifically, a handle 5 is also provided on the table leg 2 or at the bottom of the table top 3, and the handle 5 is hidden under the table top 3, which is convenient for the user to operate the handle 5. At this time, the handle 5 includes a fixed box 51 and a pull plate 52, and the fixed box 51 has an inner cavity, which provides space for the installation and movement of subsequent structures such as the pull plate 52. In addition, both ends of the fixed box 51 are respectively provided with a wire entry hole 5111 and a pull hole 5121 connected to the inner cavity. At the same time, the pull plate 52 is inserted into the pull hole 5121 and one end extends into the inner cavity, so that the subsequent user can pull the pull plate 52 and the length of the pull plate 52 extending into the inner cavity can change, which provides conditions for the subsequent pull plate 52 to pull the steel wire 4 to move. In addition, one end of the steel wire 4 passes through the wire entry hole 5111 and is connected to the end of the pull plate 52 extending into the inner cavity, so that the other end of the steel wire 4 connected to the control switch of the working cylinder can be connected to the pull plate 52, so that when the subsequent user pulls the pull plate 52, the steel wire 4 can pull the control switch to operate, thereby realizing control of the working cylinder. At the same time, a slide groove 513 is provided on the fixed box 51 and along the connecting direction from the wire entry hole 5111 to the pulling hole 5121, and one end of the pull plate 52 extending into the inner cavity is bent to form a limiting portion 521, and the limiting portion 521 extends into the slide groove 513, that is, when the user pulls the pull plate 52, the pull plate 52 can move between the pulling hole 5121 and the wire entry hole 5111 under the action of its limiting portion 521 and the slide groove 513, thereby ensuring the stability and reliability of the movement of the pull plate 52, and the pull plate 52 needs to be manually pulled to drive the steel wire 4 to move. Compared with the existing structure that uses a turning handle to control by lifting or pressing down, it is less likely to cause accidental contact, and effectively avoids the problem of accidental contact causing the working cylinder to unload force and causing the support of the desktop 3 to fail, and has higher safety assurance.

[0023] More specifically, a reset spring 53 is also provided between the fixed box 51 and the pull plate 52, and the reset spring 53 provides a condition for the pull plate 52 to automatically reset after being pulled. At this time, the reset spring 53 is sleeved on a guide rod 54, and the guide rod 54 provides a mounting base for the reset spring 53, thereby ensuring the installation position of the reset spring 53 and the position stability during the deformation process. In addition, one end of the guide rod 54 is fixed to one end of the fixed box 51 provided with the wire entry hole 5111, so that the guide rod 54 is fixedly installed on the fixed box 51, and the installation stability of the guide rod 54 is ensured. At the same time, the other end of the guide rod 54 extends toward one end of the pull hole 5121 and passes through the pull plate 52, so that the arrangement of the guide rod 54 will not interfere with the pulling of the pull plate 52, and can also provide guidance for the movement of the pull plate 52. In addition, a limiting boss 541 is provided at one end of the guide rod 54 passing through the pull plate 52, and two ends of the reset spring 53 respectively abut against the limiting portion 521 and the limiting boss 541, that is, the reset spring 53 is located between the limiting boss 541 of the guide rod 54 and the limiting portion 521 of the pull plate 52, that is, when the pull plate 52 is pulled, the limiting portion 521 moves toward the limiting boss 541, so that the reset spring 53 is compressed. When the user releases the pull plate 52, the compressed reset spring 53 automatically recovers, thereby pushing the limiting portion 521 away from the limiting boss 541, thereby realizing automatic reset of the pull plate 52, which is convenient for the next operation.

[0024] More specifically, a limiting member 55 is also provided on the pull plate 52. At this time, a hanging opening is opened on the limiting portion 521, and a pulling head 41 is provided at the end of one end where the steel wire 4 is connected to the pull plate 52. When the steel wire 4 is connected to the pull plate 52, the steel wire 4 is embedded in the hanging opening, and the pulling head 41 abuts against the side of the limiting portion 521 away from the wire entry hole 5111, that is, the steel wire 4 is limited to the pull plate 52 by the pulling head 41, so that the pull plate 52 can pull the steel wire 4 to move. The limiting member 55 is arranged on the side of the limiting portion 521 away from the wire entry hole 5111. At the same time, one end of the limiting member 55 is sleeved on the limiting portion 521, so that the limiting member 55 is installed on the limiting portion 521, so that the limiting member 55 can move with the limiting portion 521, and the other end of the limiting member 55 is bent and abuts against the side of the pull head 41 away from the limiting portion 521, that is, the pull head 41 is limited in the gap between the limiting member 55 and the limiting portion 521 by the limiting member 55, which effectively prevents the pull head 41 and the steel wire 4 from falling off, and the structure is more reliable.

[0025] More specifically, the fixing box 51 for installing the pull plate 52 includes a fixing seat 511 and a cover plate 512. The fixing seat 511 and the cover plate 512 are both plate-like structures. Both ends of the fixing seat 511 are bent toward the same side to form two edges, so that the fixing seat 511 forms a "U"-shaped structure on one side, which provides conditions for forming an inner cavity. At this time, the wire entry hole 5111 and the pull-out hole 5121 are respectively located on the two edges, that is, the edge wrapping provides a processing carrier for the wire entry hole 5111 and the pull-out hole 5121, and also provides conditions for the subsequent wire entry hole 5111 and the pull-out hole 5121 to connect to the inner cavity. At the same time, one end of the cover plate 512 is plug-connected with a rim, and the other end of the cover plate 512 is bent and fit with another rim and locked by a threaded fastener, that is, the two ends of the cover plate 512 and the two rims of the fixing seat 511 are matched and connected to form an inner cavity, and at the same time, the cover plate 512 and the fixing seat 511 are detachably connected, which is more convenient to use. In addition, the pull plate 52 and the limiter 55 are both plate-like structures. At the same time, the end of the pull plate 52 away from the limiter 521 is bent to form a handle 522, which is convenient for the user to pull the pull plate 52. In addition, by adopting a plate-like structure design for the fixing seat 511 and the cover plate 512 of the fixing box 51, as well as the pull plate 52 and the limiter 55, they can be bent and stamped, and the processing technology is simpler, the processing is more convenient, and the cost is lower.

[0026] More specifically, the handle 5 further includes a wire entry sleeve 56, which is arranged at one end of the fixing box 51 provided with the wire entry hole 5111, providing convenience for the steel wire 4 to pass through the wire entry hole 5111. In addition, the wire entry sleeve 56 further includes a sleeve rod 561 and a locking nut 562. At this time, the sleeve rod 561 is arranged as a hollow rod, and one end of the steel wire 4 passing through the wire entry hole 5111 is inserted into the sleeve rod 561, that is, the hollowness of the sleeve rod 561 provides conditions for the steel wire 4 to pass through the wire entry hole 5111. Furthermore, one end of the sleeve rod 561 is a threaded end and is inserted into the wire entry hole 5111, and locking nuts 562 are provided on the threaded end and on both sides of the edging, that is, the connection method between the sleeve rod 561 and the fixing box 51 is threaded locking, and the installation position of the sleeve rod 561 on the fixing box 51 is adjusted by adjusting the position of the locking nuts 562 on both sides. In addition, a sleeve is provided between the non-threaded end of the sleeve rod 561 and the control switch of the working cylinder, and the end of the sleeve is against the sleeve rod 561, so that when the position of the sleeve rod 561 is adjusted later, the length of the sleeve between the fixing box 51 and the control switch can change, thereby meeting the adjustment demand for the tightness of the steel wire 4, and the structural design is more reasonable.

[0027] More specifically, the handle 5 provided in this embodiment is also equipped with a safety lock assembly 6. At this time, the safety lock assembly 6 is arranged on the fixed box 51 and is located between the fixed seat 511 and the pull plate 52. That is, the movement of the pull plate 52 on the fixed seat 511 is locked and unlocked by the safety lock assembly 6, which can not only further prevent the safety problem of failure of the support of the desktop 3 caused by misoperation, but also ensure the use requirements when the desktop 3 needs to be lowered, with higher safety protection.

[0028] More specifically, the safety lock assembly 6 includes a lock tongue 61, a spring 62, a cable 63, a swing rod 64 and a button 65. At this time, guide grooves 5112 are provided on the edges of both ends of the fixed seat 511, and the guide grooves 5112 are strip grooves and the length direction is perpendicular to the direction of the slide groove 513, that is, the guide grooves 5112 have a certain length. At the same time, the movement direction of the guide grooves 5112 is the direction away from or close to the pull plate 52, which provides conditions for the subsequent guidance and unlocking of the pull plate 52 through the guide grooves 5112. At the same time, the lock tongue 61 is a plate-like structure and the two ends are respectively slidably arranged in the guide grooves 5112 at the two ends, so that the installation of the lock tongue 61 on the fixed seat 511 is realized, and the movement of the lock tongue 61 is also guided by the guide grooves 5112, which ensures the stability of the movement of the lock tongue 61. In addition, the lock tongue 61 is arranged close to the pull plate 52, which provides conditions for the subsequent lock tongue 61 and the pull plate 52 to cooperate to meet the locking and unlocking requirements. Furthermore, the locking tongue 61 is located between the pull plate 52 and the fixing seat 511, which provides conditions for the subsequent locking tongue 61 to cooperate with the pull plate 52 to achieve locking and unlocking, and the locking tongue 61 to cooperate with the fixing seat 511 to achieve the tightening of the locking tongue 61. In addition, a first matching tooth 611 is provided on the locking tongue 61 facing the pull plate 52, and a second matching tooth 523 corresponding to the first matching tooth 611 is provided on the pull plate 52 facing the locking tongue 61, that is, when the locking tongue 61 is close to the pull plate 52, the first matching tooth 611 and the second matching tooth 523 are engaged, thereby limiting the movement of the pull plate 52 and locking the pull plate 52, further preventing the pull plate 52 from accidentally moving and causing the lifting table to accidentally lose support. When the locking tongue 61 is away from the pull plate 52, the first matching tooth 611 and the second matching tooth 523 are separated, and the pull plate 52 can be smoothly pulled out, meeting the user's need to control the lifting table. At this time, the pressing spring 62 is arranged between the locking tongue 61 and the fixing seat 511, and the two ends are pressed against the locking tongue 61 and the fixing seat 511 respectively, that is, the locking tongue 61 is pressed against the pull plate 52 by the pressing spring 62, so that the locking tongue 61 can limit the movement of the pull plate 52, and the limit between the locking tongue 61 and the pull plate 52 has a certain buffer space, that is, when the external force is large, the first matching tooth 611 and the second matching tooth 523 will slide against each other, effectively avoiding the problem of structural damage caused by large external force. In addition, one end of the cable 63 is connected to the side of the locking tongue 61 away from the pull plate 52, that is, when the cable 63 is pulled, the locking tongue 61 can compress the pressing spring 62, so that the locking tongue 61 is away from the pull plate 52, so as to separate the first matching tooth 611 and the second matching tooth 523, and meet the pulling and pulling requirements of the pull plate 52.In addition, the other end of the cable 63 extends outside the fixed box 51 and is connected to one end of the rocker arm 64, that is, the cable 63 is moved by pulling the rocker arm 64. At the same time, the middle part of the rocker arm 64 is rotatably installed on the fixed box 51, and the button 65 is installed on the fixed box 51 and is located on the edge provided with the pulling hole 5121. At the same time, the button 65 is pressed against the other end of the rocker arm 64, that is, when the user presses the button 65, the rocker arm 64 swings around its middle, so that the other end of the rocker arm 64 can pull the cable 63 to move, and the lock tongue 61 is pulled away from the pull plate 52 by the cable 63, so as to unlock the pull plate 52, thereby meeting the normal pulling and pulling requirements. In addition, since the button 65 is arranged on the edge of the fixed box 51 with the pull-out hole 5121, the button 65 and the handle 522 of the pull plate 52 are at the same end of the fixed box 51, so that it is convenient for the user to press the button 65 with the thumb while pulling the pull plate 52 with other fingers, meeting the need for one-handed operation, and the structural design is more reasonable. It is worth pointing out that after the pulling is completed, the user only needs to keep pressing the button 65, and the pull plate 52 will automatically reset under the action of the reset spring 53. After the pull plate 52 is reset, the user can release the button 65 to complete the re-locking of the pull plate 52, which is more convenient to use.

[0029] In addition, in order to improve the safety of the lifting table during lifting, the present embodiment also provides a structure in which a monitoring component 7 is set on the desktop 3. At this time, the monitoring component 7 is set at the bottom of the desktop 3, so that the monitoring component 7 is hidden. In addition, since the items on the desktop 3 can be easily found within the user's field of vision during the lifting process, and the items under the desktop 3 are easily ignored by the user's field of vision, the monitoring component 7 is set at the bottom of the desktop 3 to better meet the monitoring needs during the lifting process of the lifting table. In addition, the monitoring component 7 includes a monitoring sensor and a controller. The controller is installed on the bottom surface of the desktop 3, which also hides the controller and improves the aesthetics. At the same time, a number of monitoring sensors are set, and the monitoring sensors are evenly distributed on the bottom surface of the desktop 3 and arranged toward the bottom surface, that is, a number of monitoring sensors are used to achieve full-range monitoring of the bottom space of the desktop 3, and the monitoring range is wider, which effectively prevents the problem of collision during the lifting process, and the safety guarantee is higher. At the same time, each monitoring sensor is connected to the controller in communication, that is, the signal detected by each monitoring sensor can be transmitted to the controller, and processed by the controller, which provides conditions for subsequent anti-collision prompts.

[0030] More specifically, a plurality of sockets are provided on the bottom surface of the desktop 3, and a monitoring sensor is disposed in each socket, that is, the socket provides an installation space for the monitoring sensor, so that the monitoring sensor is hidden on the bottom surface of the desktop 3. At the same time, each monitoring sensor is electrically connected to a transmitting module. Preferably, the transmitting module is embedded in the socket where the corresponding monitoring sensor is located, that is, the signal detected by the monitoring sensor can be transmitted to the transmitting module through a wire and transmitted through the transmitting module. At the same time, the transmitting module has a built-in power supply to realize self-power supply. In addition, a receiving module that communicates with the transmitting module is provided in the controller, and the transmitting module and the receiving module are wirelessly connected, that is, the signal transmitted by the transmitting module can be received by the receiving module, thereby meeting the monitoring signal transmission requirements, and also avoiding the problem of excessive wiring at the bottom of the desktop 3 affecting the aesthetics, and the structural design is more reasonable.

[0031] More specifically, the controller is also electrically connected to an alarm, preferably, the alarm is a speaker, which can emit a prompt sound, providing conditions for the user to obtain anti-collision information in time. At the same time, the controller has a built-in power supply, which provides power for the operation of the alarm, the information processing of the controller, and the communication between the controller and the monitoring sensor.

[0032] As a preferred embodiment, the monitoring sensor is a millimeter wave radar sensor, which has strong anti-interference ability, accurate detection, and can be directly purchased with low operating cost.

[0033] The lifting table with a wire handle provided in the present embodiment comprises a handle 5 with a fixed box 51 and a pull plate 52; one end of the wire 4 connected to the control switch of the working rod is connected to the pull plate 52, and one end of the pull plate 52 is extended into the inner cavity of the fixed box 51, and the pull plate 52 is installed through the fixed box 51 and serves as a guide for pulling and pulling the pull plate 52, so that the user can drive the wire 4 to move by pulling and pulling the pull plate 52, thereby realizing control of the working cylinder. Compared with the structure of the traditional handle that needs to be lifted or pressed down to control, it not only meets the lifting and lowering requirements of the lifting table, but also enables the control of the lifting table to be changed from the original lifting or pressing down to a pulling type, and the possibility of preventing accidental collision and causing the support failure of the desktop 3 is smaller, the safety guarantee is higher, and it is conducive to the use of the lifting table.

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.
