基于气弹簧原理的外接储气缸或罐联动同步升降桌Synchronous lifting table with external cylinder or tank linkage based on gas spring principle 技术领域Technical field
本发明涉及一种家俱，尤其是一种能确保同步升降的外接储气缸(罐)联动气弹簧同步升降桌，具体地说是一种基于气弹簧原理的外接储气缸或罐联动同步升降桌。The invention relates to a piece of furniture, in particular to an external air storage cylinder (tank) linkage gas spring synchronous lifting table capable of ensuring synchronous lifting, in particular to an external air storage cylinder or tank linkage synchronization lifting table based on the gas spring principle.
背景技术Background technique
人们办公和学***稳的问题，加大了用户的操作难度；市场上的双气动伸缩杆调节高度的办公桌会出现因各气弹簧相互独立，无法协调两根气杆(气弹簧)同步伸缩和负载不均的问题，导致桌面倾斜，出现卡阻现象，同样没有很好的用户体验，同时由于空间限制，传统气弹簧直径和长度不可以造的很大，制约了气弹簧内部高压气体或者油气混合物的封存体积，特别是负载较大时，造成了上升时力量较轻松，下降时力量巨大，使用者非常吃力的情况。People use a variety of desks when working and studying. Long-term use of ordinary traditional desks can easily cause cervical, lumbar diseases and other diseases in the process of sitting and studying. Properly changing the posture of standing and using the table can effectively prevent the cervical spine. The occurrence of diseases, lumbar spondylosis, etc., scientific research has shown that the harmfulness of sitting for a long time is even greater than the harm caused by smoking, and standing office for a long time can consume a certain amount of extra calories, maintain the body and weight, and contribute to the overall health of the body. In order to suit users of different body heights, the existing lifting desks have designed various hand-cranked, double or even multi-motor electric height adjustment desks and single and double air rods (gas springs) adjustable height desks. The manual lifting adopts the principle of mechanical gear transmission. It is completely dependent on the manual shaking of the handle to lift the desktop and the load through the gear structure transmission. When the desktop rises, the hand feels heavy, and the load is too heavy, which can easily cause the situation that ordinary users cannot use it. The large force causes the rocker arm to deform, the transmission gear and other devices are damaged, and the service life is not long; and the double or even multi-motor electric height adjustment desk needs to install multiple sets of motors and electrical and mechanical drive systems, and double or even multi-motor electric adjustment In order to keep each motor synchronized during high use, a multi-motor synchronization controller is required. Therefore, it is noisy and has a high failure rate. It must also be used in an area with a power socket. The area is limited and cannot be moved freely. Moreover, the price of dual or even multi-motor and mechanical drive system is not close to the people, so that the double or even multi-motor electric lifting desk can not be promoted in a large area; single and double air rods (gas spring) adjustable height desks do not need power supply, and can be operated by manpower. , Green and environmental protection, the use area is not limited, and you can move around freely, but the ordinary single pneumatic telescopic rod adjustable height desk only supports a gas rod (gas spring) and pillar in the middle of the desktop, and there is a problem of unstable installation of the table body. It increases the difficulty of the user’s operation; the desks with dual pneumatic telescopic rods on the market that adjust the height will have problems that the air springs are independent of each other and cannot coordinate the simultaneous expansion of the two air rods (gas springs) and uneven load, resulting in the desktop Tilting, jamming occurs, and there is also no good user experience. At the same time, due to space constraints, the diameter and length of traditional gas springs cannot be made too large, which restricts the storage volume of high-pressure gas or oil-gas mixture inside the gas spring, especially the load When it is larger, the power is easier when ascending, and the power is huge when descending, and the user is very strenuous.

本发明的有益效果：The beneficial effects of the present invention:
由于气弹簧传动方便快捷，无需电源，还原和蓄能效率高，其具有高效、安全和稳定特性，数十年以来已经用于生产和生活的方方面面，只要放置两个或数个完全相同的气弹簧和外接储气罐(缸)，两个或数个气弹簧通过管道与各个相对应的外接储气罐(缸)一对一完全对接，还可以同步传导甚至高于99％以上的位移，同时辅以换向阀或截止阀及闸阀等阀门控制驱动活塞杆77在气弹簧中的移动和锁定，同时外接储气罐(缸)的应用极大地降低了使用者的体力要求，这样的动力传导效率和位移效率完全满足日常办公和学习的需求，特别也满足了妇女儿童及老人的使用要求，没有了电源线的羁绊，移动使用方便安全，极具方便性和人性化。Because the gas spring drive is convenient and fast, does not require power supply, it has high recovery and energy storage efficiency. It has the characteristics of high efficiency, safety and stability. It has been used in all aspects of production and life for decades, as long as two or more identical gas is placed The spring and the external gas storage tank (cylinder), two or several gas springs are fully connected to each corresponding external gas storage tank (cylinder) through the pipeline, and can also transmit even more than 99% of the displacement simultaneously. At the same time, it is supplemented by valves such as reversing valve or stop valve and gate valve to control the movement and locking of the driving piston rod 77 in the gas spring. At the same time, the application of an external gas storage tank (cylinder) greatly reduces the user's physical requirements. The conduction efficiency and displacement efficiency fully meet the needs of daily office and study, especially the use requirements of women, children and the elderly. Without the fetters of the power cord, it is convenient and safe to move and use, and it is very convenient and user-friendly.
根据这一特性，用气弹簧作为动力源，通过2个或多个外接储气缸(罐)联动气弹簧组成的联动件就可以实现两个甚至两个以上的升降腿同时同向做相同力量的同量位移运动，彻底解决了单一单动力源不能使所有桌脚同步和多个动力源容易产生相互干涉造成***不协 调甚至卡阻问题，在所有桌脚负载不均时不会出现桌面倾斜、卡阻现象，具有操作方便、承载力大、同步性好，反应速度快、性能稳定可靠，不因为重物放在桌子一端而引起在升降过程中桌面倾斜，有很好的用户体验；外接储气缸(罐)的应用极大地降低了使用者的体力要求，满足了妇女儿童及老人的使用要求。同时传导***可使用柔性管道，满足桌子在升高和降低的位移中的位移要求而不会损坏，且由于管道柔性伸缩的特性，同一套装置可以满足不同尺寸的桌面的办公桌***使用普通的气弹簧***具有高效稳定，结构简单，价格低廉，使用寿命长久的特点，一般的气弹簧***全寿命一般达到几万甚至十几万次往复运动，按正常升降办公桌每天30次升降使用计算，正常使用条件下可以达到甚至超过10年以上使用寿命，况且可以其使用高压氮气、高压空气等高压气体或者油气混合物传导介质，绿色环保，取材方便价格低廉，维护方便，不受恶劣天气影响。According to this feature, using a gas spring as the power source, two or more external accumulators (tanks) linked to the gas spring can achieve two or more lifting legs simultaneously doing the same force in the same direction. The same amount of displacement movement completely solves the problem that a single power source cannot synchronize all table legs and multiple power sources easily interfere with each other, causing system incoordination or even jamming. When all table legs are loaded unevenly, the desktop will not tilt, Jamming phenomenon, convenient operation, large bearing capacity, good synchronization, fast response speed, stable and reliable performance, does not cause the desktop to tilt during the lifting process due to heavy objects on one end of the table, and has a good user experience; external storage The application of the cylinder (tank) greatly reduces the user's physical requirements and meets the requirements of women, children and the elderly. At the same time, the conduction system can use flexible pipes to meet the table’s displacement requirements during elevated and lowered displacements without damage, and due to the flexible expansion and contraction characteristics of the pipes, the same set of devices can meet the requirements of desk systems with different sizes of desks. The gas spring system has the characteristics of high efficiency and stability, simple structure, low price, and long service life. The full life of a general gas spring system generally reaches tens of thousands or even hundreds of thousands of reciprocating movements. It is calculated according to the normal lifting desk 30 times a day. Under normal conditions of use, the service life can reach or exceed 10 years. Moreover, it can use high-pressure nitrogen, high-pressure air and other high-pressure gas or oil-gas mixture conduction media, which is green and environmentally friendly, convenient to obtain materials, low price, easy to maintain, and not affected by bad weather.

It includes a table top 1 and a base 4. The table top 1 has at least two (this embodiment takes two as an example for illustration, multiple connections can be (See Figure 9) The lifting leg 3 made on the basis of the gas spring principle is mounted on the base 4. The lifting leg 3 is composed of a piston rod 77, a cylinder 33 and a power cylinder or tank 57. A cylinder 33 has a rod cavity It communicates with the rodless cavity of the other cylinder 33 and also communicates with the storage cavity 88 of the power cylinder or tank 57 as the driving power. The rod cavity of the last cylinder 33 and the rodless cavity of the first cylinder 33 The chamber communicates with the storage chamber 88 of the last power cylinder or tank 57. The high-pressure gas or gas-liquid mixture in the power chamber 99 of the power cylinder or tank 57 provides power for the desktop lifting. The gas-liquid mixture compresses energy storage. In Figure 1 (retracted state), the rodless end of the cylinder 3 is fixedly connected to the base 4, and the piston rod 77 is connected to the desktop 1 through the extended arm support 5. As shown in Figure 1, the lifting leg 3 is installed in the telescopic assembly In the sleeve forming the table leg 2, the rod cavity of the first cylinder 33 is connected to the rodless cavity of the second cylinder 33 through the flexible pipe 6, and the rod cavity of the second cylinder 33 passes through the flexible pipe 6. Connected to the rodless cavity of the first cylinder block 33; meanwhile, the rod cavity of each cylinder block is connected to a pipe one to one to a separate power cylinder or tank (that is, an external gas storage tank (cylinder), the same below ) 57, in order to facilitate the up and down movement of the piston rod 77, the medium (one of gas, oil, oil-water, water, aqueous solution, oil and gas mixture) is in the cylinder 33 (part with the piston rod 77) of the gas spring and the external gas storage tank (cylinder) ) 57, each gas spring cylinder 33 (part with piston rod 77) is connected to the storage cavity 88 (used to store the same medium as the cylinder) of each external gas storage tank (cylinder) 57 through a pipeline. For one-to-one connection, the gas spring cylinder 33 (part with piston rod 77) no longer stores high-pressure gas or oil and gas mixture, but instead stores it in an external gas storage tank (cylinder) 57, and each external gas storage tank (cylinder) ) 57 can be connected rigidly in the same direction (Figure 6) or not connected (Figure 5); when the valve (A) is opened by operating the switch 18, the cylinder 33 of each gas spring is due to the pressure of the rod cavity and the rodless cavity The difference causes the piston rod 77 to generate upward thrust. The upward thrust of each piston rod 77 subtracts the weight of the table 1 and the moving parts and the movement friction is the difference F1, and the valve (A) has been opened at this time, when F1 is a positive value, at the same time Push the piston rod 77 of the gas spring 3 on the left and right sides to move upward.
在图6的原理图中我们看到，左、右两侧的气弹簧为内部及外观结构完全相同的型号、与其相对应连接的两个外接储气罐(缸)57亦是内部及外观结构完全相同的型号，在此时图6的右侧的初始状态下，通过柔性管道6的连接，两组封闭状态下的介质((油液、水、水溶液、气、气液混合物))的总体体积S是相同的，分别是各个气弹簧的无杆腔体积E(e)加上另一个气弹簧的有杆腔体积d(D)加上对应的外接储气罐(缸)57b(B)(由于柔性管道6中的介质((油液、水、水溶液、气、气液混合物))体积一直充满不变，是一个恒定值，所以可以在讨论各个变量的公式中可以忽略不记)In the schematic diagram of Figure 6, we can see that the gas springs on the left and right sides have the same internal and external structure. The two external gas storage tanks (cylinders) 57 connected to them are also internal and external. Exactly the same model, in the initial state on the right side of Figure 6 at this time, through the connection of the flexible pipe 6, the totality of the two closed state media ((oil, water, aqueous solution, gas, gas-liquid mixture)) The volume S is the same, which are the rodless cavity volume E(e) of each gas spring plus the rod cavity volume d(D) of another gas spring plus the corresponding external gas storage tank (cylinder) 57b(B) (Because the volume of the medium ((oil, water, aqueous solution, gas, gas-liquid mixture)) in the flexible pipe 6 is always full and constant, it is a constant value, so it can be ignored in the formula for discussing each variable)
即图6右侧的初始状态下：That is, in the initial state on the right side of Figure 6:
E+d+b＝e+D+B＝SE+d+b=e+D+B=S
又由于两个外接储气缸(罐)是刚性同向相连接，所以任何情况下：Because the two external storage cylinders (tanks) are rigidly connected in the same direction, in any case:
b＝Bb=B
又由于左、右两侧的气弹簧为内部及外观结构完全相同的型号And because the gas springs on the left and right sides are identical in internal and external structure
所以两气弹簧的内部体积相同：So the internal volume of the two gas springs is the same:
E+D＝e+dE+D=e+d
所以以上公式演变为：So the above formula evolved into:
E+d＝e+DE+d=e+D
E+D＝e+dE+D=e+d
则：then:
E＝eE=e
D＝dD=d
就是说，无论活塞杆77向上运动和向下运动到何种状态下，左、右两侧的气弹簧的缸体有杆腔和无杆腔的对应体积都是相同的，就是说左、右两侧的气弹簧的活塞杆77都是在同样高度的位置，同时辅以换向阀或截止阀及闸阀等阀门A控制驱动活塞杆77在气弹簧中的移动和锁定,就可以带动桌面1平稳水平平稳上升、下降和锁定任意位置。That is to say, no matter what state the piston rod 77 moves up and down, the corresponding volumes of the rod cavity and rodless cavity of the gas spring cylinders on the left and right sides are the same, that is, the left and right The piston rods 77 of the gas springs on both sides are at the same height position. At the same time, the valve A, such as a reversing valve, a shut-off valve, and a gate valve, controls the movement and locking of the driving piston rod 77 in the gas spring, which can drive the desktop 1 Stable level rise, fall and lock any position steadily.
左、右两侧的气弹簧的无杆腔容积变大，有杆腔容积变小时，与其相对应连接的外接储气罐(缸)57的存储腔88中的介质(油液、水、水溶液、气、气液混合物)通过柔性管道6挤入左、右两侧气弹簧无杆腔中作为无杆腔和有杆腔同等位移量时体积差的补充，使其对应的外接储气罐(缸)57的存储腔88容积变小，同时推动刚性同向相连接的另一个外接储气罐(缸)57的存储腔88容积同相同体积变小，通过柔性管道6使右侧气弹簧缸体33 (以下简称气弹簧)的有杆腔内的介质(油液、水、水溶液、气、气液混合物)补充过来，使另一侧气弹簧3有杆腔中介质(油液、水、水溶液、气、气液混合物)体积变小，带动各气弹簧的活塞杆77伸长，左右气弹簧型号相同时，各气弹簧有杆腔和无杆腔直径和体积相同，各活塞杆77长度和直径亦相同时，此时各弹簧的活塞杆77运动速度和位移相同，带动桌面1平稳水平上升；操控开关18带动阀门(A)关闭时，各气弹簧虽然有杆腔和无杆腔压力差使活塞杆77向上产生推力F1，但此时阀门(A)已关闭，左侧气弹簧有杆腔中的介质(油液、水、水溶液、气、气液混合物)不可以向右侧气弹簧的无杆腔中移动，右侧气弹簧有杆腔中的介质(油液、水、水溶液、气、气液混合物)亦不可以向左侧气弹簧的无杆腔中移动，此时各气弹簧的活塞杆77锁定，促使桌面1高度锁定；桌面1上升后；如图2所示，当操控开关18带动阀门(A)打开时，同时向桌面1上施加向下的力F2，F2大于F1时，且此时阀门(A)已打开，迫使右侧气弹簧的无杆腔的介质(油液、水、水溶液、气、气液混合物)向左侧气弹簧有杆腔中移动，同时左侧气弹簧无杆腔中的介质(油液、水、水溶液、气、气液混合物)向右侧气弹簧的有杆腔中移动，带动各气弹簧的活塞杆77缩短，左右气弹簧型号相同时，各气弹簧有杆腔和无杆腔直径和体积相同，各活塞杆77长度和直径亦相同时，此时各弹簧的活塞杆77运动速度和位移相同，带动桌面1平稳水平下降；操控开关18带动阀门(A)关闭时，虽然向桌面1上施加向下的力F2，且F2大于F1，但此时阀门(A)已关闭，各气弹簧各腔中的介质(油液、水、水溶液、气、气液混合物)不可以向别的气弹簧腔中移动，此时各气弹簧的活塞杆77锁定，促使桌面1高度锁定。其原理图如图9、10所示，采用图9的原理图右侧摆放时，各个气弹簧的无杆端均固定在底座4(或桌面1上)上，各个活塞杆77的端部均通过一个加长臂托5与桌面1固定相连，也可以采用图9的原理图左侧摆放，各个气弹簧的无杆端均通过加长臂托5固定在桌面1上，各个活塞杆77的端部固定在底座1一；采用图10的原理图时，一个气弹簧的无杆端固定在底座，另一个气弹簧的无杆端通过加长臂托5固定在桌面1上。The volume of the rodless cavity of the gas spring on the left and right sides becomes larger, and the volume of the rod cavity becomes smaller. The medium (oil, water, aqueous solution) in the storage cavity 88 of the external gas storage tank (cylinder) 57 connected to it correspondingly , Gas, gas-liquid mixture) through the flexible pipe 6 squeezed into the left and right side gas spring rodless cavity as a supplement for the volume difference when the rodless cavity and the rod cavity have the same displacement, so that the corresponding external gas storage tank ( The volume of the storage chamber 88 of the cylinder 57 becomes smaller, and at the same time, the volume of the storage chamber 88 of another external gas storage tank (cylinder) 57 that is rigidly connected in the same direction is reduced with the same volume, and the right gas spring cylinder is made through the flexible pipe 6 The medium (oil, water, aqueous solution, gas, and gas-liquid mixture) in the rod cavity of the body 33 (hereinafter referred to as gas spring) is replenished so that the gas spring 3 on the other side has the medium (oil, water, The volume of the water solution, gas, gas-liquid mixture) becomes smaller, which drives the piston rod 77 of each gas spring to extend. When the left and right gas springs are of the same model, each gas spring has a rod cavity and a rodless cavity with the same diameter and volume, and each piston rod 77 length When the diameter is the same, the movement speed and displacement of the piston rod 77 of each spring are the same, which drives the table top 1 to rise steadily and horizontally; when the valve (A) is closed by the control switch 18, although each gas spring has a rod cavity and a rodless cavity pressure The difference causes the piston rod 77 to generate a thrust F1 upwards, but at this time the valve (A) has been closed, and the left gas spring has the medium (oil, water, aqueous solution, gas, gas and liquid mixture) in the rod cavity and cannot move to the right gas spring The rodless cavity of the gas spring on the right side (oil, water, aqueous solution, gas, gas and liquid mixture) in the rod cavity cannot move to the rodless cavity of the left gas spring. The piston rod 77 is locked to cause the table top 1 to be locked in height; after the table top 1 rises; as shown in Figure 2, when the valve (A) is opened by the control switch 18, a downward force F2 is simultaneously applied to the table top 1, and when F2 is greater than F1 , And the valve (A) has been opened at this time, forcing the medium (oil, water, aqueous solution, gas, gas and liquid mixture) in the rodless cavity of the gas spring on the right to move to the rod cavity of the gas spring on the left, and at the same time The medium (oil, water, aqueous solution, gas, gas-liquid mixture) in the spring rodless cavity moves to the rod cavity of the right gas spring, driving the piston rod 77 of each gas spring to shorten. When the left and right gas springs are of the same model, each When the gas spring has the same diameter and volume as the rod cavity and the rodless cavity, and the length and diameter of each piston rod 77 are also the same, at this time the movement speed and displacement of the piston rod 77 of each spring are the same, driving the table top 1 to drop smoothly and horizontally; the control switch 18 drives When the valve (A) is closed, although the downward force F2 is applied to the desktop 1 and F2 is greater than F1, the valve (A) is closed at this time, and the medium (oil, water, aqueous solution, The gas, gas-liquid mixture) cannot move to other gas spring chambers. At this time, the piston rod 77 of each gas spring is locked, which promotes the height of the table top 1 to lock. The principle diagrams are shown in Figures 9 and 10. When the principle diagram of Figure 9 is placed on the right side, the rodless ends of each gas spring are fixed on the base 4 (or the desktop 1), and the ends of each piston rod 77 They are all fixedly connected to the desktop 1 through an extended arm support 5, or they can be placed on the left side of the schematic diagram of FIG. 9, the rodless ends of each gas spring are fixed on the desktop 1 through the extended arm support 5, and the piston rod 77 The end is fixed on the base 1; when the principle diagram of FIG. 10 is used, the rodless end of one gas spring is fixed on the base, and the rodless end of the other gas spring is fixed on the desktop 1 through the extended arm support 5.
具体实施时，当桌面的长度较长或带动转弯结构时，需要三根或以上的升降腿进行支撑时，为了操作方便，也可以为第一个气弹簧的有杆腔与第二个气弹簧的无杆腔相连通，第二个气弹簧的有杆腔与第三个气弹簧的无杆腔相连通，第三个气弹簧的有杆腔与第四个气弹簧的无杆腔相连通，以此类推，最后一个气弹簧的有杆腔与第一个气弹簧的无杆腔相连通；同时各气弹簧的有杆腔处外接一根管道一对一到一个单独的外接储气罐(缸)57上，以方便活塞杆77上下运动时介质((油液、水、水溶液、气、气液混合物))在气弹簧(带活塞杆77部分)和外接储气罐(缸)57之间流动，各个气弹簧(带活塞杆77部分)通过管道 与各个外接储气罐(缸)57单独一对一对应相连接，气弹簧(带活塞杆77部分)不再存储介质((油液、水、水溶液、气、气液混合物))，而是改存到外接储气罐(缸)57内部，各外接储气罐(缸)57最好是如图6一样采用刚性同向相连接，采用图5所示的非刚性连接也可使桌面水平使用，但下压时需要使二个活塞杆受力相当。In specific implementation, when the length of the desktop is long or the turning structure is driven, when three or more lifting legs are required for support, for easy operation, it can also be the rod cavity of the first gas spring and the second gas spring. The rodless cavity is connected, the rod cavity of the second gas spring is connected to the rodless cavity of the third gas spring, and the rod cavity of the third gas spring is connected to the rodless cavity of the fourth gas spring. By analogy, the rod cavity of the last gas spring is connected to the rodless cavity of the first gas spring; at the same time, the rod cavity of each gas spring is connected to a pipe one to one to a separate external gas storage tank ( Cylinder) 57 to facilitate the medium ((oil, water, aqueous solution, gas, gas-liquid mixture)) when the piston rod 77 moves up and down between the gas spring (part with piston rod 77) and the external gas storage tank (cylinder) 57 Each gas spring (part 77 with piston rod) is connected to each external gas storage tank (cylinder) 57 individually one-to-one correspondence through pipes, and the gas spring (part 77 with piston rod) no longer stores the medium ((oil) , Water, aqueous solution, gas, gas-liquid mixture)), but stored in the external gas storage tank (cylinder) 57, each external gas storage tank (cylinder) 57 is preferably connected in the same direction as shown in Figure 6. , The non-rigid connection shown in Figure 5 can also be used to make the desktop horizontal, but the two piston rods need to be equally stressed when pressing down.
如果桌面有两块以上组成，且要调节每块桌面的升降高度时，可采用增大或缩小支撑对应桌面的气弹簧的容积、改变活塞杆77长度等措施来加以实现。If the table top is composed of more than two pieces, and the height of each table top needs to be adjusted, measures such as increasing or reducing the volume of the gas spring supporting the corresponding table top and changing the length of the piston rod 77 can be adopted to achieve this.
具体实施时亦可以在每一条柔性管道6上装上阀门(A)，通过1个或数个操控开关18来控制阀门(A)的打开或闭合，以达到控制桌面1的升降和位置锁定。During specific implementation, a valve (A) can also be installed on each flexible pipe 6, and one or more control switches 18 can be used to control the opening or closing of the valve (A), so as to control the lifting and position locking of the table top 1.
