Description

Press device and lifting drive and same table

Technical field

The utility model relates to press device and lifting drive and same tables.

Background technique

House should have been arrived more and more by acting on lifting device with the spring that fluid (such as gas or liquid) is resisting medium In tool, such as Publication No. CN106308039A discloses a kind of lifting device, and in the lifting device, one end of spring is located at It is fixed in first sleeve and with one end of first sleeve；The control assembly of control spring closure or openness, which is drivingly connected component, makes bullet The valve of spring forms closure or openness, and control assembly is connect with connection component.Control assembly includes: activation lever, support, drawing Line, one end of activation lever are equipped with the casing for receiving bracing wire traction head, and the end face of activation lever setting casing is equipped with Arc groove, in the another equipped with handle of activation lever, which protrudes from the surface of activation lever.

When specific operation, the hand of operator buttresses activation lever from the adaptation groove in activation lever, adds to activation lever rotation Active force, activation lever around the hinge joint of connecting column and the first connecting column rotate, activation lever during rotation, guiding parts Activation lever is oriented to, activation lever drives bracing wire to carry out folding and unfolding along the circumferencial direction of casing, and bracing wire drives bracing wire to connect Fitting rotation, bracing wire connector pushes the displacement of spool control-rod, thus make the valve opening of spring, inside shape of the fluid in spring At flowing, active force is being applied to the piston rod of spring by another hand or other objects, so as to so that piston rod is gone up and down, And then spring fastenings and the second casing is successively driven to go up and down.

Above-mentioned control assembly is mounted on the lower surface of desktop, i.e., the control assembly of this structure cannot be mounted on first set The inside of pipe, otherwise operator can not open or close spring to rotational control assemblies, to also just cannot achieve control table The purpose of face lifting.That is control assembly can be only installed at outside first sleeve or on other parts, however, due to control Component need to be attached by bracing wire and spring, in this way, control assembly and a part of bracing wire are exposed outside first sleeve, Influence is produced so as to cause the appearance on product.

Summary of the invention

The purpose of this utility model is to provide one kind can be embedded into the object used formed with the object it is integrated Press device.

The technical solution for solving above-mentioned technical problem is as follows:

Press device, comprising:

Shell, one end of shell are equipped with the accommodating chamber axially arranged along the shell, and the circumferential surface of shell is equipped with along this The mounting hole that shell is radially arranged, shell are equipped with the first hinge member and the second hinge member being located in accommodating chamber；

A part of pressing component, the pressing component is entered in the accommodating chamber of shell by the mounting hole, press section One end of part is flexibly connected with the first hinge member, the other end of the pressing component and inner wall of shell is supported or press section The other end of part is connected by the inner wall of extensible member and shell；

Lever in accommodating chamber, the middle part of lever and the second hinge member are hinged, the first end of lever and pressing Component is supported, and the second end of lever is load connecting pin, when applying active force by first end of the pressing component to lever, Lever makes the second end generate active force to load around the rotation of the second hinge member.

The press device of the utility model is made of shell, pressing component and lever, and the press device of this structure exists In use, lever is around second when generating active force by applying pressing active force to pressing component with the first end to lever Hinge member rotation makes the second end generate active force to load, and therefore, the utility model can be directly embedded into the object used One is formed with the object (such as lifting drive) in body, and the object for avoiding and using is separated into two parts, due to Press device can integrally be embedded into the object used, both make to melt for an entirety, therefore, from the appearance for, more Beauty, and after combining together with the object used, it is needed without as existing control assembly from desktop when carrying On disassemble (installation of existing control assembly on the table, by bracing wire and the gas spring output end that is arranged in table leg Connection component connection, therefore, if individually carrying table leg, needs to disassemble control assembly from desktop).

The another object of the utility model is to provide a kind of compact-sized lifting drive.

The technical solution for solving above-mentioned technical problem is as follows:

Lifting drive, including outer tube, gas spring, gas spring top rod driving component, bracing wire component, gas spring are located at outer It further include end cap and press device in pipe, one end of gas spring top rod driving component is located at cover internal and fixes with end cap Connection, the other end of gas spring top rod driving component are located in outer tube and are fixedly connected with outer tube, set in the piston rod of gas spring There is the mandril for opening gas spring, after the piston rod of gas spring is fixedly connected with gas spring top rod driving component, in the piston rod Mandril supported with gas spring top rod driving component, one end of the bracing wire component is connect with gas spring top rod driving component, draw The second end of the lever of the other end and press device of line component connects, and the circumferential surface on the outer tube is equipped with mounting hole, presses Pressure device is located in the mounting hole.

The lifting drive of the utility model, since press device to be embedded into outer tube, bracing wire component is hidden in outer In pipe, therefore, bracing wire component can't see in the outside of lifting drive, and pressure is applied to pressing component when in use, Pressing component is gone up and down together in company with the components such as outer tube, therefore, the utility model by press device be embedded into outer tube with Afterwards, it does not have an impact in use not only, it is also more compact, reasonable in structure.

A further object of the utility model is to provide a kind of simple same table of structure.

The technical solution for solving above-mentioned technical problem is as follows:

A kind of same table, including pedestal, desktop, further include support member and lifting drive, and the gas spring is solid It is scheduled on pedestal, the support member is equipped with hole, and support member covers in gas spring, the shell of support member and press device It is fixedly connected, desktop is clamped between outer tube and support member.

The same table of this structure, since desktop is clamped between outer tube and support member, when lifting drive liter When drop, desktop and support member are gone up and down together with outer tube, therefore, structurally, only need a lifting device The lifting of desktop can be driven in driving device, and not only structure is simple, and can save cost.
