Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology for engineering machinery buckets, and in particular to a loader cylinder ruler fixing device. Background Technology

[0002] The main function of the loader bucket cylinder is to provide power and help the bucket complete various actions. When the operator controls the bucket in the cab, it is not easy to observe the extension and retraction of the cylinder, which can easily lead to the bucket suddenly rising, falling, or tilting excessively. In addition, during the movement of the bucket, loose material inside the bucket can easily spill out. If the spilled material adheres to or scratches the piston rod of the cylinder, it can easily cause oil leakage in the cylinder, resulting in the bucket not moving as intended. Utility Model Content

[0003] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a loader cylinder gauge fixing device.

[0004] Technical solution: To achieve the above objective, this utility model discloses a loader cylinder gauge fixing device, which includes a cylinder rod seat connected to the end of the cylinder piston rod, a gauge and a support seat. The two ends of the support seat are detachably connected to the cylinder rod seat and the gauge, respectively. One end of the gauge extends and covers the cylinder piston rod.

[0005] Preferably, the oil rod seat has at least one threaded hole on the side near the support seat.

[0006] Preferably, the support base is provided with a through hole adapted to the threaded hole, the through hole penetrating the support base body for bolt passage.

[0007] Preferably, the scale has a circular hole that matches the through hole, and the scale, support base, and oil rod base are connected by bolts.

[0008] Preferably, the oil rod seat has at least one first positioning hole on the side near the support seat.

[0009] Preferably, the support base has a first protrusion on the side near the oil rod seat that is embedded in the first positioning hole and whose diameter is adapted to the hole.

[0010] Preferably, the support base has a second protrusion on the side near the scale, and the scale has a second positioning hole for the second protrusion to pass through and which is adapted to the shape of the second protrusion.

[0011] Preferably, the support base is made of plastic and the scale is made of stainless steel.

[0012] The beneficial effects of this utility model are:

[0013] 1. This device improves the structure of the hydraulic cylinder's piston rod seat, allowing the support seat and scale to be detachably connected to the piston rod seat. When the operator controls the bucket in the cab, this device extends and retracts along with the hydraulic cylinder piston rod. By observing the scale and using it as a reference, the operator can more accurately control the bucket's movement speed, avoiding sudden rises, falls, or excessive tilting of the bucket due to the sudden large extension and retraction of the hydraulic cylinder piston rod.

[0014] 2. The scale extends above the piston rod of the hydraulic cylinder. When bulk materials spill, it can protect the piston rod of the hydraulic cylinder to prevent the piston rod from sticking to the bulk materials or being scratched, which could cause oil leakage inside the hydraulic cylinder.

[0015] 3. This device adopts a detachable structure, and supports of different heights and scales of different lengths and widths can be replaced for different cylinders, making it more versatile and reducing manufacturing and replacement costs compared to an integrated structure.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0022] A loader cylinder dipstick fixing device, such as Figures 1-4 As shown, the device includes a rod seat 4 connected to the end of the piston rod 5 of the hydraulic cylinder, a scale 1, and a support base 3. One end of the scale 1 extends and covers the top of the piston rod 5 of the hydraulic cylinder, and the scale 1 can protect the piston rod 5 of the hydraulic cylinder. The two end faces of the support base 3 are detachably connected to the rod seat 4 and the scale 1, respectively.

[0023] Furthermore, to achieve a detachable connection between the scale 1, support base 3, and oil rod seat 4, the oil rod seat 4 has at least one threaded hole 7 on the side near the support base 3. The support base 3 has a through hole 8 that matches the threaded hole 7, and the through hole 8 passes through the body of the support base 3 for the bolt 2 to pass through. The scale 1 has a round hole 9 that matches the through hole 8. The scale 1, support base 3, and oil rod seat 4 are connected by bolts 2. In this embodiment, there are two threaded holes 7 and two through holes 8, and one round hole 9. The bolt 2 passes through the scale 1 and support base 3 in sequence and engages with the threaded hole 7 to achieve fastening. The number of threaded holes 7, through holes 8, and round holes 9 can be set by those skilled in the art according to actual needs. Of course, the detachable connection method of the scale 1, support base 3, and oil rod seat 4 is not limited to fastening with bolts 2. It can also be achieved by setting connecting pins or connecting threads, or other techniques commonly used by those skilled in the art, as long as the disassembly and assembly requirements are met.

[0024] Furthermore, in order to prevent the bolt 2 from loosening due to external force during use, and to ensure the accuracy of the installation position and increase the connection strength, the oil rod seat 4 is provided with at least one first positioning hole 10 on the side near the support seat 3, the support seat 3 is provided with a first protrusion 11 that is embedded in the first positioning hole 10 and matches its hole diameter on the side near the oil rod seat 4, the support seat 3 is provided with a second protrusion 6 on the side near the scale 1, and the scale 1 is provided with a second positioning hole 12 for the second protrusion 6 to pass through and match the shape of the second protrusion 6. In this embodiment, the number of the first protrusion 11 and the second protrusion 6 is one.

[0025] Furthermore, to reduce the weight of the device, the support base 3 is made of plastic and is stamped. The scale 1 is made of stainless steel. In practical applications, the support base 3 can be replaced with different height specifications to avoid interference with the cylinder. At the same time, the scale 1 can be replaced with different lengths and widths. This device is connected to the end of the hydraulic cylinder piston rod 5 through the hydraulic rod seat 4. When the operator operates the bucket in the cab, this device moves along with the hydraulic cylinder piston rod 5. By observing the scale 1 and using it as a reference, the operator can more accurately control the movement speed of the bucket and efficiently adjust the bucket to the appropriate position. This avoids the bucket from suddenly rising, falling, or tilting excessively due to the sudden large extension and retraction of the hydraulic cylinder piston rod 5, which could cause material spillage. At the same time, the scale 1 extends above the hydraulic cylinder piston rod 5, which can protect the hydraulic cylinder piston rod 5 when loose material spills, preventing the hydraulic cylinder piston rod from being stuck with loose material or scratched, thus preventing oil leakage from the cylinder.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
