[0029] Embodiment 1:

[0030] like Figure 1As shown, a multi-pressure source linkage device for spring rod type handle assembly comprises a base 3, a guide column 7 arranged on the base 3, a first positioning seat 2 arranged between the base 3 and the guide column 7, a second positioning seat 6 and a third positioning seat 8 slidably arranged on the guide column 7, a spindle mounting seat 1 is arranged on the first positioning seat 2, a first limiting hole 16 is arranged on the second positioning seat 6, and a second limiting hole 14 is arranged on the third positioning seat 8, a height limiting mechanism 18 and a reset mechanism 20 are arranged between the base 3 and the second positioning seat 6, a first driver 5 is arranged between the base 3 and the third positioning seat 8, and a retaining spring pressing mechanism 10 is arranged on the third positioning seat 8, the third positioning seat 8 slides up and down along the guide column 7 through the first driver 5, the second positioning seat 6 is synchronously linked and moved and pressed toward the first positioning seat 2 along the guide column 7 by the pressure of the third positioning seat 8, and the second positioning seat 6 after being released slides upward along the guide column 7 through the reset mechanism 20 and is limited and fixed by the height limiting mechanism 18.

[0031] In the whole multi-pressure source linkage device, the first positioning seat 2 is fixed on the base 3, the second positioning seat 6 and the third positioning seat 8 are slidably installed through the guide column 7, and at the same time, the third positioning seat 8 and the base 3 are connected through the first driver 5, and the first driver 5 can control the third positioning seat 8 to slide up and down along the guide column 7, and the second positioning seat 6 is pushed upward by the reset mechanism 20 and limited in the height direction by the height limiting mechanism 18, so that the first positioning seat 2, the second positioning seat 6 and the third positioning seat 8 can be spaced apart in the initial state, which is convenient for placing each hand component of the assembled spring rod type grip, and the second positioning seat The seat 6 is driven by the third positioning seat 8 to slide downward and move synchronously along the guide column 7 to the first positioning seat 2 and press it. In the process of assembling the spring rod type handle, it is only necessary to fix one end of the main shaft through the main shaft mounting seat 1, and place the preliminarily assembled pressing piece, spring piece, base inner and surface cover assembly into the first limiting hole 16. The third positioning seat 8 can be driven by the first driver 5 to move along the guide column 7 toward the second positioning seat 6. The preliminarily assembled pressing piece, spring piece, base inner and surface cover assembly is pressed down through the bottom surface of the third positioning seat 8, and the second positioning seat 6 and the third positioning seat 8 are synchronously driven toward the first positioning seat 6. By moving the positioning seat 2, the main shaft can be inserted into the base. During the process, the base assembly and the main shaft can be assembled by moving the second positioning seat 6 downward. At the same time, the clamping force of the second positioning seat 6 and the third positioning seat 8 can be used to realize the compression assembly of the base assembly, which effectively solves the problems existing in the existing base assembly and the manual installation between the base assembly and the main shaft. When assembling the retaining spring, it is only necessary to put the retaining spring into the second limiting hole 14, and by starting the retaining spring clamping mechanism 10 to move the retaining spring to be installed downward along the main shaft and tighten it, the retaining spring can be accurately installed in the groove of the retaining spring outside the main shaft, and manual labor is no longer required during the entire assembly process. The knocking and clamping assembly will not cause problems such as damaged parts and personal injury, and the assembly has high assembly accuracy, high work efficiency, and low labor intensity, which effectively solves the problem of troublesome assembly of existing spring rod handles. After assembly and the first driver 5 and the retaining spring clamping mechanism 10 are reset, the second positioning seat 6 can be reset by the reset mechanism 20 and the height is limited by the height limiting mechanism 18, so that the driving mechanism is reduced and the structure is simpler. The first positioning seat 2, the second positioning seat 6 and the third positioning seat 8 are limited by the guide column 7, which can make the entire assembly process more accurate and coaxial, and avoid the problem of misalignment in assembly.

[0032] Further improved, the retaining spring clamping mechanism 10 includes a support plate 9 arranged on the third positioning seat 8, a second driver 11 arranged on the support plate 9, and a retaining spring pressure rod 13 controlled by the second driver 11 to rise and fall, and the retaining spring pressure rod 13 is suspended above the second limiting hole 14 through the support plate 9.

[0033] When assembling the retaining spring to be installed through the retaining spring clamping mechanism 10, the second driver 11 is installed directly above the second limiting hole 14 through the support plate 9, so that a sufficient height interval is formed between the end of the retaining spring pressure rod 13 and the second limiting hole 14, and the retaining spring to be installed can be directly picked up by hand and placed in the second limiting hole 14, and then the retaining spring pressure rod 13 can be pushed to move and install and fix through the retaining spring pressure rod 13 by starting the second driver 11. The clamping depth is accurately controlled during the entire installation process, which is convenient and efficient for the installation of the retaining spring. It effectively solves the problem that the existing retaining springs need to be assembled with tools such as retaining spring pliers during installation, making the installation of the retaining spring simple and convenient, and the spindle and base assembly do not require any manual movement. While having high precision, the operation is more convenient, and one-time assembly and molding can be achieved, avoiding the problem of secondary assembly.

[0034] A further improvement is that a third limiting hole 12 is provided on the support plate 9 , and the retaining spring pressure rod 13 is a hollow tube, and one end of the retaining spring pressure rod 13 passes through the third limiting hole 12 .

[0035] The retaining spring pressure rod 13 is a hollow tube and one end thereof passes through the third limiting hole 12, so that the second driver 11 can be installed above the support plate 9, and the support plate 9 can be directly installed on the third positioning seat 8, thereby making the entire device more compact and the relative position accuracy between the support plate 9 and the third positioning seat 8 higher. It can not only avoid the problem of high difficulty in controlling the relative position accuracy between the support plate 9 and the third positioning seat 8 when the second driver 11 is installed between the support plate 9 and the third positioning seat 8, but also avoid the problem of left and right shaking of the retaining spring pressure rod 13 due to the lack of radial limitation after installation, so that the retaining spring pressure rod 13 will not deviate when assembling the retaining spring. The retaining spring pressure rod 13 adopts a hollow tube structure, and its hollow hole contour is larger than the main shaft and smaller than the outer diameter of the retaining spring, which can make its structure simpler and the production cost lower. Among them, the inner hole of the retaining spring pressure rod 13 adopts a circular hole structure, which is more convenient to obtain materials.

[0036] Further improvement is as follows: Figure 2 As shown, the spindle mounting seat 1 includes a fixing plate 25, a fixing seat 28 arranged on the fixing plate 25, and a positioning pin 26 arranged on the fixing seat 28. The bottom of the spindle to be assembled is installed and positioned by the positioning pin 26; a positioning hole 27 is provided on the fixing seat 28, and one end of the positioning pin 26 is detachably installed in the positioning hole 27.

[0037] The spindle mounting seat 1 is composed of a fixing plate 25, a fixing seat 28 and a locating pin 26, wherein the fixing plate 25 is mounted on the first locating seat 2 by fixing parts such as bolts, and the guide column 7 is fixed on the base 3 after passing through the first locating seat 2. During assembly, the relative position control between the first locating seat 2, the second locating seat 6 and the third locating seat 8 can be more convenient to avoid misalignment after assembly, and the locating pin 26 is installed on the fixing plate 25 through the fixing seat 28, which can make it more convenient to install the spindle on the mounting seat. By adding the fixing seat 28, the installation stability of the locating pin 26 can be better, the thickness of the fixing plate 25 can be made thinner, and the overall weight can be made lighter. In order to facilitate the replacement of the fixing pin, a locating hole 27 is formed on the fixing seat 28, which can facilitate the replacement of the locating pin 26. When spindles with different inner holes need to be assembled, the replacement of the locating pin 26 is convenient, making the use range of the entire device wider.

[0038] As a further improvement, a groove 15 is provided on both the front and rear sides of the third positioning seat 8 and the supporting plate 9, and the second driver 11 is supported and positioned by four pillars.

[0039] An inwardly recessed groove 15 is formed on both the front and rear sides of the third positioning seat 8 and the support plate 9, and the second limiting hole 14 is located in the middle of the two grooves 15. When the retaining spring is inserted, the buckle can be placed more accurately, avoiding the problem of the second limiting hole 14 being too far from the side and being placed outside during operation. The second driver 11 is supported and positioned by four pillars, which can not only ensure the installation stability of the second driver 11, but also avoid the problem that after the retaining spring pressure rod 13 is installed, the retaining spring pressure rod 13 is too close to the second limiting hole 14 and it is inconvenient to place the retaining spring.

[0040] As a further improvement, the height limiting mechanism 18 includes two limiting blocks 19 arranged on the fixing plate 25 , and limiting grooves 17 are arranged inside the limiting blocks 19 , and both sides of the second positioning seat 6 slide along the limiting grooves 17 .

[0041] The height limiting mechanism 18 is composed of two limiting blocks 19 whose bottoms are installed on the fixed plate 25. The inner side of the limiting block 19 is provided with a limiting groove 17, so that after the two sides of the second positioning seat 6 slide along the limiting groove 17, the height direction can be limited by the limiting block 19. The structure is simple and easy to install. In particular, when the limiting block 19 forms an L-shaped structure through the limiting groove 17, the inner top of the limiting block 19 forms an outwardly protruding hook structure, and the side surface of the second positioning seat 6 can form a surface contact with the limiting groove 17, which has better stability, is more convenient for the production of the limiting block 19, and is simpler for height limitation. Compared with other limiting structures, the structure is simpler while achieving the required function.

[0042] A further improvement is that the reset mechanism 20 includes reset springs 22 symmetrically arranged on both sides of the second limiting hole 14, the first positioning seat 2 is provided with a through hole 4 for passing the reset spring 22, and the two ends of the reset spring 22 are respectively installed on the second positioning seat 6 and the base 3.

[0043] The reset spring 22 is symmetrically installed on both sides of the second limiting hole 14. After the reset spring 22 passes through the first positioning seat 2 through the through hole 4, the two ends are respectively installed on the bottom of the second positioning seat 6 and the base 3, so that the reset spring 22 can ensure the verticality without other external limiting structures, and can also prevent the problem of detaching from the device due to bending deformation after being compressed, making the installation of the reset spring 22 simpler and more convenient. Moreover, resetting by the reset spring 22 has a simple structure and a stable reset effect, and the replacement cost is also lower, and the later maintenance is convenient and not easy to be damaged.

[0044] Further improvement is as follows: Figure 3 As shown, the first limiting hole 16 is a stepped hole, a trumpet-shaped guide hole 29 is provided at the upper end of the second limiting hole 14 , and two guide posts 7 are symmetrically arranged on the bottom plate 23 .

[0045] The first limiting hole 16 is a stepped hole, which can realize the installation limit of the base assembly and the extension of the main shaft, and the upper end of the second limiting hole 14 is a trumpet-shaped guide hole 29 design, which can make it easier to insert the retaining spring. After insertion, it can automatically guide and correct the horizontality to avoid the problem of misplacement.

[0046] As a further improvement, both the first driver 5 and the second driver 11 are cylinder structures, and both ends of the third positioning seat 8 are mounted on the piston rod of the first driver 5 .

[0047] The first driver 5 and the second driver 11 are both cylinder structures, which are simpler in structure and more convenient to control. Among them, the first driver 5 adopts two symmetrical arrangements, and the two ends of the third positioning seat 8 are symmetrically installed on the piston rod of the first driver 5. When the third positioning seat 8 is lifted and lowered, the stability is better, and the control speed and pressure are more convenient to adjust.

[0048] Further improved, the base 3 includes a bottom plate 23, a plurality of support blocks 24 arranged on the bottom plate 23, the bottom of the fixed plate 25 is arranged on the support block 24, and the height of the fixed plate 25 is fixed by the support block 24; and a plurality of hanging rings 21 are also arranged on the side of the bottom plate 23.

[0049] The fixing plate 25 is fixed by the support block 24, which can make the height position control of the fixing plate 25 more convenient. At the same time, the support block 24 adopts a multi-block design, which can make the weight of the entire base 3 lighter when the height of the fixing plate 25 is controlled. Among them, the support block 24 adopts three blocks, two of which are located at the bottom of both sides of the fixing plate 25, and the other is located directly below the fixing seat 28. During the pressing process, the stability of the fixing plate 25 can be better and will not be deformed due to the force in the middle. The entire device is basically made of metals such as stainless steel. Four lifting rings 21 are installed on the side of the bottom plate 23. When it needs to be moved, it can be lifted by the lifting ring 21, thereby solving the problem of the inconvenience of moving the entire device.

[0050] Embodiment 2:

[0051] A further improvement on the basis of Example 1 is as follows: Figure 4 As shown, a conical guide head 30 is also included, and the guide head 30 is installed on the top of the main shaft to be assembled.

[0052] When installing the retaining spring on the main shaft, since the top of the main shaft is a flat structure, it is difficult to align and sleeve the retaining spring on the outside when inserting it, and manual adjustment or slow insertion is often required, resulting in low operation efficiency and operational risks. Therefore, in order to solve this problem, the multi-pressure source linkage device also includes a conical guide head 30, and a plug rod protrudes downward from the bottom of the conical guide head 30. Before assembling the retaining spring, the conical guide head 30 is inserted into the top of the main shaft through the plug rod, so that the top of the main shaft forms a guide structure through the conical guide head 30. When assembling the retaining spring, the operator only needs to ensure that the retaining spring is aligned with the top of the conical guide head 30 and sleeved in, and then the retaining spring can be accurately sleeved on the outside of the main shaft through the conical guide head 30. When placing the retaining spring, there is no need to worry about the problem of shelving or misalignment.

[0053] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
