Description

Technical Field

[0001] The utility model relates to the field of multi-way valve flexible shafts, in particular to a mounting bracket structure for a multi-way valve flexible shaft. Background Art

[0002] The multi-way valve is mainly used for hydraulic switching control of equipment such as cranes and excavators, and a multi-way valve flexible shaft needs to be connected thereto. The multi-way valve flexible shaft is mainly fixed on the mechanical equipment through a mounting bracket. However, the existing mounting brackets generally can only fix multi-way valve flexible shafts with the same diameter. When one of the flexible shafts needs to be repaired or replaced, the entire mounting bracket needs to be disassembled, which causes the remaining flexible shafts to be separated from the mounting bracket, and is not conducive to the installation and fixation of the remaining flexible shafts. Content of the Utility Model

[0003] The purpose of the utility model is to provide a mounting bracket structure for a multi-way valve flexible shaft to overcome the above-mentioned defects in the prior art.

[0004] According to the mounting bracket structure for a multi-way valve flexible shaft of the utility model, it includes a fixed seat. The fixed seat is in a "U" shape composed of a horizontal part and two vertical parts. A clamping assembly for simultaneously clamping or separately clamping multiple flexible shafts is arranged in the fixed seat. The clamping assembly includes a bottom plate, a pressing plate, a plurality of lower clamping plates and a plurality of upper clamping plates. The bottom plate is fixed on the horizontal part of the fixed seat. The pressing plate is slidably connected in the fixed seat and moves up and down. The pressing plate is arranged on the upper side of the bottom plate. A plurality of upper clamping plates are slidably connected in the pressing plate and move up and down. A plurality of limit threaded rods are in threaded connection with the upper end surface of the pressing plate, and the lower ends of the plurality of limit threaded rods abut against the upper end surfaces of the upper clamping plates. A part of the upper clamping plate 21 can slide downward out of the pressing plate 20, and the plurality of upper clamping plates are respectively aligned with the plurality of lower clamping plates one by one.

[0005] Through the above technical solution, after rotating the limit threaded rod, the adjacent upper clamping plate and the lower clamping plate cooperate with each other to clamp the multi-way valve flexible shaft, thereby fixing the multi-way valve flexible shaft. The upper clamping plate can slide in the pressing plate, so that the distance between the upper clamping plate and the lower clamping plate can be adjusted. Furthermore, the clamping assembly can clamp multi-way valve flexible shafts with different diameters. By reversing a single limit threaded rod, it can be realized that a single upper clamping plate can be adjusted to be away from the corresponding lower clamping plate on the corresponding side, thereby facilitating the disassembly of a single flexible shaft.

[0006] Furthermore, a plurality of lower clamping plate cavities are arranged in the bottom plate at equal intervals along the width direction of the fixed seat. The upper ends of the lower clamping plate cavities are open. The number of the lower clamping plate cavities is the same as the number of the lower clamping plates. The plurality of lower clamping plates are respectively slidably connected in the plurality of lower clamping plate cavities. Springs are fixed between the bottom surfaces of the lower clamping plates and the bottom walls of the lower clamping plate cavities.

[0007] With the above technical solution, under the elastic force of the spring, several lower clamping plates can cooperate with several upper clamping plates to clamp the flexible shaft at the same time, so as to fix the flexible shaft simultaneously and improve the installation efficiency of the flexible shaft.

[0008] Furthermore, several concave empty grooves that are recessed downward are formed on the upper end surface of the bottom plate, and several of the concave empty grooves penetrate several lower clamping plate cavities along the thickness direction of the bottom plate. A clamping groove that is recessed downward is formed on the upper end surface of the lower clamping plate, and the curvature of the clamping groove is smaller than that of the concave empty groove.

[0009] With the above technical solution, it is beneficial to increase the stability of the flexible shaft installation, and at the same time, the smaller curvature of the clamping groove than that of the concave empty groove is beneficial to expanding the clamping range of the lower clamping plate and the upper clamping plate for flexible shafts with different diameters.

[0010] Furthermore, a groove is formed by the downward depression on the lower end surface of the pressing plate. Two symmetrically arranged positioning blocks are fixed on the lower side surface of the upper clamping plate. A positioning cavity is formed in the bottom wall of the clamping groove, and the positioning blocks are slidably connected in the positioning cavity, and the upper clamping plate can be slidably matched with the positioning cavity.

[0011] With the above technical solution, it is beneficial to improve the clamping accuracy of the upper clamping plate and the lower clamping plate.

[0012] Furthermore, a limiting groove that penetrates along its thickness direction is formed on the pressing plate, and a limiting rod that slides in the limiting groove is fixed on the upper clamping plate.

[0013] With the above technical solution, the setting of the limiting rod can prevent the upper clamping plate from sliding out of the pressing plate and improve the convenience of clamping the flexible shaft by several upper clamping plates at the same time.

[0014] Furthermore, clamping grooves are fixedly provided on the side surfaces of the vertical parts of the fixed seats close to the pressing plate, and the two side edges of the pressing plate are respectively slidably connected in the clamping grooves on both sides.

[0015] With the above technical solution, the setting of the clamping grooves is beneficial to increasing the positioning accuracy between the pressing plate and the bottom plate.

[0016] Furthermore, threaded holes perpendicular to the vertical parts of the fixed seats are formed in the parts of the pressing plate located in the clamping grooves, through holes corresponding to the threaded holes on the pressing plate are formed in the vertical parts of the fixed seats, and positioning threaded rods that penetrate the through holes on the fixed seats are threadedly connected in the threaded holes on the pressing plate.

[0017] With the above technical solution, after the positioning threaded rod passes through the through hole on the fixed seat and is connected to the threaded hole on the pressing plate, it can ensure that the pressing plate is fixed in the fixed seat.

[0018] The beneficial effects of the present utility model are as follows: After rotating the limiting threaded rod, the adjacent upper clamping plates and lower clamping plates cooperate in pairs to clamp the multi-way valve flexible shaft, thereby fixing the multi-way valve flexible shaft. The upper clamping plate can slide on the pressure plate, so that the distance between the upper clamping plate and the lower clamping plate can be adjusted. Furthermore, the clamping assembly can clamp multi-way valve flexible shafts with different diameters. By reversing a single limiting threaded rod, it is possible to adjust a single upper clamping plate to move away from the corresponding lower clamping plate on one side, which is convenient for disassembling a single flexible shaft.

[0028] An embodiment of the present utility model:

[0029] Referring to Figures 1 - 5 , the present utility model provides a multi-way valve flexible shaft mounting bracket structure, which includes a fixed seat 10. The fixed seat 10 is in a "U" shape composed of a horizontal part and two vertical parts. A clamping assembly for simultaneously clamping or separately clamping multiple flexible shafts is arranged in the fixed seat 10. The clamping assembly includes a bottom plate 30, a pressing plate 20, a plurality of lower clamping plates 32 and a plurality of upper clamping plates 21. The bottom plate 30 is fixed on the horizontal part of the fixed seat 10. The pressing plate 20 is slidably connected in the fixed seat 10 and moves up and down. The pressing plate 20 is arranged on the upper side of the bottom plate 30. A plurality of upper clamping plates 21 are slidably connected in the pressing plate 20 and move up and down. A plurality of limit threaded rods 24 are threadedly connected to the upper end surface of the pressing plate 20, and the lower ends of the plurality of limit threaded rods 24 abut against the upper end surface of the upper clamping plate 21. A part of the upper clamping plate 21 can slide out of the pressing plate 20 downward, and the plurality of upper clamping plates 21 are respectively aligned with the plurality of lower clamping plates 32 one by one.

[0030] Referring to Figure 4 、 Figure 5 , a plurality of lower clamping plate cavities 301 are arranged in the bottom plate 30 at equal intervals along the width direction of the fixed seat 10. The upper end of the lower clamping plate cavity 301 is open, and the number of the lower clamping plate cavities 301 is the same as the number of the lower clamping plates 32. The plurality of lower clamping plates 32 are respectively slidably connected in the plurality of lower clamping plate cavities 301. A spring 31 is fixed between the bottom surface of the lower clamping plate 32 and the bottom wall of the lower clamping plate cavity 301. The spring 31 is in a wave shape made of steel and has a certain elastic deformation ability.

[0031] Referring to Figure 5 , a plurality of concave empty grooves 302 are arranged on the upper end surface of the bottom plate 30 and recess downward. The plurality of concave empty grooves 302 respectively penetrate through the plurality of lower clamping plate cavities 301 along the thickness direction of the bottom plate 30. A clamping groove 322 recesses downward is arranged on the upper end surface of the lower clamping plate 32. The curvature of the clamping groove 322 is smaller than the curvature of the concave empty groove 302.

[0032] Referring to Figure 5, a groove is formed by the downward depression of the lower end face of the pressing plate 20, and the curvature of the groove is consistent with that of the positioning cavity 321. Two symmetrically arranged positioning blocks 211 are fixed on the lower side surface of the upper clamping plate 21. A positioning cavity 321 is formed in the bottom wall of the clamping groove 322. The positioning block 211 is slidably connected in the positioning cavity 321. The upper clamping plate 21 can be slidably matched with the positioning cavity 321. An arc-shaped groove is formed by the upward depression of the lower end face of the pressing plate 20, and the curvature of the arc-shaped groove is consistent with that of the concave empty groove 302.

[0033] Refer to Figure 5 , a limiting groove 22 is formed through the pressing plate 20 along its thickness direction, and a limiting rod 23 that slides in the limiting groove 22 is fixed on the upper clamping plate 21.

[0034] Refer to Figure 2 , clamping grooves 11 are fixedly arranged on the side surfaces close to the pressing plate 20 of the vertical parts of the fixing seats 10. The two side edges of the pressing plate 20 are respectively slidably connected in the clamping grooves 11 on both sides.

[0035] Refer to Figure 2 、 Figure 4 , threaded holes perpendicular to the vertical parts of the fixing seats 10 are formed in the parts of the pressing plate 20 located in the clamping grooves 11. Through holes corresponding to the threaded holes on the pressing plate 20 are formed in the vertical parts of the fixing seats 10. Positioning threaded rods 40 that penetrate through the through holes on the fixing seats 10 are threadedly connected in the threaded holes on the pressing plate 20.

[0036] According to the diameter of the soft shaft to be clamped, rotate the limiting threaded rod 24 so that the lower end of the limiting threaded rod 24 moves downward, and then the upper clamping plate 21 moves downward.

[0037] Then place the soft shafts to be clamped on each lower clamping plate 32 respectively, and then snap the pressing plate 20 into the clamping groove 11 and slide it downward until the lower end of the positioning block 211 slides into the positioning cavity 321. Clamp the soft shafts through the upper clamping plate 21 and the lower clamping plate 32, and the spring 31 is in a compressed state.

[0038] At this time, pass the positioning threaded rod 40 through the through hole on the fixing seat 10 and connect it to the threaded hole on the pressing plate 20, so as to fix the pressing plate 20 on the fixing seat 10 and ensure the stability of the clamping assembly for clamping the soft shaft.

[0039] When it is necessary to replace and repair a certain soft shaft, reverse the limiting threaded rod 24, then the limiting threaded rod 24 moves upward, and then the upper clamping plate 21 can move upward. At this time, remove the soft shaft port from the multi-way valve. Since the upper clamping plate 21 can move away from the lower clamping plate 32 at this time, then move the upper clamping plate 21 upward so that the distance between the upper clamping plate 21 and the lower clamping plate 32 is greater than the port diameter of the soft shaft, and then the soft shaft can be pulled out from between the upper clamping plate 21 and the lower clamping plate 32, which is convenient for the repair and replacement of a single soft shaft.

[0040] Those skilled in the art can clearly understand that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present utility model. All of them fall within the protection scope of the present utility model. The protection scheme of the present utility model shall be subject to the appended claims of the present utility model.
