Description

Technical Field

[0001] This utility model relates to the field of instrument panels, specifically an instrument panel that is easy to disassemble. Background Technology

[0002] Existing instrument dials are directly and completely fixed to the instrument housing, which makes it difficult to repair and replace them when they are damaged. If the instrument components malfunction, parts need to be replaced or repaired, and disassembly and installation are quite complicated. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an instrument dial that is easy to disassemble, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an easily detachable instrument dial, comprising an instrument housing, the instrument housing being a cylindrical shell, a retaining ring fixedly disposed in the middle of the inner sidewall of the instrument housing, the retaining ring having four semi-circular notches arranged in a circumferential array on its inner edge, bushings fixedly disposed on the left and right sides of the bottom center of the instrument housing, fixing ears fixedly disposed on the bottom center and the rear edge of the instrument housing, and a clamping assembly fitted inside the front and rear fixing ears, the clamping assembly comprising an H-shaped top that is movably inserted into the left and right bushings at its left and right ends respectively. The H-shaped top clamping pin has a first spring fitted on the bushings on both sides. The front and rear fixed ears have movable insert top rods. The front end and one-third of the rear side of the top rod are respectively fixedly connected to vertical rods. The upper ends of the front and rear vertical rods are respectively fixedly connected to the front and rear ends of the lower side of the pressure block. The lower front end of the pressure block is a platform, and the rear side of the platform is an inclined surface. The top rod at the rear of the rear fixed ear is fitted with a second spring. The top rod at the rear of the second spring is fixedly fitted with a spring retaining ring. The upper opening of the instrument housing is secured to the dial assembly through the retaining ring.

[0005] Furthermore, a through hole is provided on the rear side wall of the housing directly opposite the top rod.

[0006] Furthermore, the dial assembly includes a top cover that matches the upper opening of the instrument housing. The dial is embedded in the upper surface of the top cover. A fixing ring is fixedly connected to the circumferential edge of the lower surface of the dial. A chuck is fixedly connected to the lower end of the fixing ring. Four semi-circular protrusions are arranged in a circumferential array on the circumferential edge of the chuck. Two insertion holes are symmetrically opened on the lower part of the chuck, directly opposite the center of the circumference of both ends of the H-shaped top clamping pin.

[0007] Furthermore, the semi-circular protrusion matches the semi-circular notch.

[0008] Furthermore, the insertion holes on both sides are not on the center line connecting the two semi-circular protrusions that are symmetrical about any axis, and the insertion holes match the insertion posts at both ends of the H-shaped tightening pin. This design of the insertion holes can prevent the dial assembly from being stuck and unable to rotate when it is inserted through the semi-circular notch of the corresponding retaining ring of the semi-circular protrusion.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By inserting the chuck of the dial assembly into the instrument housing and rotating the dial assembly, the four semi-circular protrusions on the edge of the chuck rotate to the semi-circular notches of the retaining ring inside the instrument housing. Pressing the dial assembly downwards positions the semi-circular protrusions under the retaining ring, and rotating it further causes the pins at both ends of the H-shaped locking pin of the clamping assembly to be inserted into the corresponding holes on the chuck. This achieves quick clamping and fixing between the dial assembly and the instrument housing. When disassembling and repairing the dial assembly, only a pin needs to be inserted. Push the push rod forward through the through hole on the rear side of the instrument housing. The push rod moves the pressure block forward, causing the inclined surface of the pressure block to push the middle crossbar of the H-shaped clamping pin downward. This causes the two end posts of the H-shaped clamping pin to be pulled out of their corresponding holes. Rotate the dial assembly again, causing the four semi-circular protrusions on the edge of the chuck to rotate to the semi-circular notch of the retaining ring inside the instrument housing. Release the push rod, and under the action of the second spring and the first spring, the H-shaped clamping pin pushes the chuck out of the retaining ring, thus completing the disassembly of the dial assembly and improving the disassembly efficiency of the dial assembly.

Through hole 14, clamping assembly 2 is installed inside the front and rear fixing ears 13. The clamping assembly 2 includes H-shaped clamping pins 21 that are movably inserted into the left and right bushings 12 at their left and right ends respectively. First springs 22 are installed on the bushings on the left and right sides of the H-shaped clamping pins 21. Push rods 23 are movably inserted into the front and rear fixing ears 13. The front end and one-third of the rear side of the push rods 23 are respectively fixedly connected to vertical rods 24. The upper ends of the front and rear vertical rods 24 are respectively fixedly connected to the front and rear ends of the lower side of the pressure block 25. The lower front end of the pressure-stopping block 25 is a platform, and the rear side of the platform is an inclined surface. A second spring 26 is fitted onto the top rod at the rear of the fixing lug 13. A spring fixing ring 27 is fixedly fitted onto the top rod at the rear of the second spring 26. The upper opening of the instrument housing 1 is secured to the dial assembly 3 via the retaining ring 11. The dial assembly 3 includes a top cover 31 that matches the upper opening of the instrument housing 1. The upper surface of the top cover 31 is embedded with a dial 32, and the lower circumferential edge of the dial 32 is fixedly connected to it. Ring 33, the lower end of the fixed ring 33 is fixedly connected to chuck 34, the circumferential edge of the chuck 34 is arranged with 4 semi-circular protrusions 341, the semi-circular protrusions 341 match the semi-circular notch 111, the lower part of the chuck 34 is symmetrically opened with two insertion holes 342 on the circumference of the two ends of the H-shaped tightening pin 21, the insertion holes 342 on both sides are not on the line connecting the center of the two semi-circular protrusions 341 that are symmetrical about any axis, and the insertion holes 342 match the insertion posts at both ends of the H-shaped tightening pin 21.

[0016] In use: Insert the chuck 34 of the dial assembly 3 into the instrument housing 1, rotate the dial assembly 3 so that the four semi-circular protrusions 341 on the edge of the chuck 34 rotate to the semi-circular notches 111 of the retaining ring 11 inside the instrument housing 1, press the dial assembly 3 down so that the semi-circular protrusions 341 are placed under the retaining ring 11, and rotate again so that the pins at both ends of the H-shaped locking pin 21 of the clamping assembly 2 are inserted into the corresponding insertion holes 342 on the chuck 34, thereby achieving quick clamping and fixing between the dial assembly 3 and the instrument housing 1. When disassembling and repairing the dial assembly 3, simply insert the push pin into the through hole 14 on the rear side of the instrument housing 1, push the push rod 23 forward, and push... Rod 23 moves the pressure block 25 forward, causing the inclined surface of the pressure block 25 to push the middle crossbar of the H-shaped clamping pin 21 downward, thereby causing the two end posts of the H-shaped clamping pin 21 to be pulled out from the corresponding insertion holes 342.
