Description

Technical Field

[0001] The utility model relates to the technical field of deburring brushes, in particular to an adjustable heat sink deburring brush. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. For example, a CPU (Central Processing Unit) in a computer requires a quite large heat sink, and power tubes, line tubes in a TV set, and power amplifier tubes in a power amplifier all require heat sinks. Generally, a layer of thermal grease needs to be applied on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink.

[0003] When manufacturing and processing heat sinks, the process steps include deburring. During the deburring process step, it is difficult for machine equipment to fully contact the grooved surface of the heat sink. Therefore, some burrs will remain at the bottom of the groove or in the groove, and then it is necessary to manually clean them with a deburring brush. However, the traditional deburring brush is not convenient for adjusting the protruding length of the bristles and the distribution gap between each row of bristles. Therefore, it is difficult to apply heat sinks with different groove depths and spacings, resulting in an increase in usage costs and a decrease in cleaning efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the traditional deburring brush is difficult to apply heat sinks with different groove depths and spacings, and provide an adjustable heat sink deburring brush.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] The utility model provides an adjustable heat sink deburring brush, including

[0007] A limit holding plate, with a number of limit card slots opened under the limit holding plate;

[0008] A mounting frame, which is installed on one side close to the limit card slot. The mounting frame is hinged to the proximal end of the limit holding plate, and the distal ends of the mounting frame and the limit holding plate are movably connected by connecting screws;

[0009] A bristle plate, which is movably penetrated through the mounting frame by mounting screws. The upper end of the bristle plate is inserted into the limit card slot; the lower end of the bristle plate is slidably connected with bristles up and down.

[0010] Further, the opening direction of the limit card slot is the same as the length direction of the bristle plate.

[0011] Furthermore, the mounting frame is in a "U"-shaped structure, the brush plate is mounted on the inner side of the mounting frame, and the open end of the mounting frame is hinged to the limiting handheld plate.

[0012] Furthermore, a rotating rod is fixedly connected to the open end of the mounting frame, and a hinge seat is provided under the limit handheld plate.

[0013] The hinge seat is provided with a through hole, and the rotating rod is rotationally matched with the through hole.

[0014] Furthermore, the bristle plate includes a penetration connecting plate, the upper end of the penetration connecting plate is penetrated on the penetration screw, the lower end of the penetration connecting plate is vertically opened with a slide groove, a sliding adjustment plate is connected in the slide groove for up and down sliding, and the bristles are arranged on the bottom of the sliding adjustment plate; the sliding adjustment plate and the slide groove are connected by an adjustment locking mechanism.

[0015] Furthermore, the adjustment locking mechanism includes a push-on pin; a pin slide groove is provided on the side wall of the sliding adjustment plate, the push-on pin is slidably passed through the pin slide groove, the bottom of the pin slide groove is connected to one end of the push-on pin through a spring, and a plurality of pin slots are provided on the slide groove for the push-on pin to pass through.

[0016] The beneficial effects of the utility model are:

[0017] 1. By sliding the brush plate onto the mounting screw, the distance between the two brush plates can be adjusted by sliding, so that they can be placed in the grooves of the heat sinks with different distances. In addition, the threaded connection design of the screws realizes the detachable function, so that the excess brush plates can be removed, thereby preventing too many brush plates from piling up on one side and affecting their use. After adjusting the distance between several brush plates, the limit handheld plate is closed, and the limit slot on the limit handheld plate clamps the upper end of the brush plate in the slot, thereby playing a fixed limit role, preventing it from sliding again on its own, and facilitating subsequent use.

[0018] 2. By dividing the structure of the brush plate into two plates that slide against each other, and the two plates are connected by an adjustable locking mechanism, on the one hand, not only can the distance between the bristles and the limiting handheld plate be adjusted, but the brush plate can also be extended to the bottom of grooves of different groove depths for deburring, thereby improving the deburring cleaning efficiency and expanding the scope of application. On the other hand, the pop-up push-pin pin also makes it easier to fix the extended length of the sliding adjustment plate to prevent rebound during use and ensure stability in use. In addition, the relative position of the sliding adjustment plate can be further adjusted by pressing it lightly, which is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Through this solution, the insertion connecting plate 31 can be slidably inserted on the insertion screw 21 to facilitate the adjustment of the spacing, making it more suitable for heat sinks with different groove spacings; and then through the transition cooperation with the limit card slot 11, when used with the hinge structure, the limit handheld plate 1 and the mounting frame 2 can be combined together to achieve fixed limit of several insertion connecting plates 31, preventing them from sliding by themselves during use and affecting use.

[0038] A slide groove 312 is vertically opened at the lower end of the wearing connecting plate 31 , and the sliding adjustment plate 32 is slidably arranged in the slide groove 312 and connected through the adjustment locking mechanism 4 , and bristles 33 are arranged at the bottom thereof.

[0039] Specifically, the adjustment locking mechanism 4 includes a push-on pin 321; a pin slide groove 323 is provided on the side wall of the sliding adjustment plate 32, and the push-on pin 321 slides through the pin slide groove 323. The bottom of the pin slide groove 323 is connected to one end of the push-on pin 321 through a spring 322, and a plurality of pin slots 311 are provided on the slide groove 312 for the push-on pin 321 to pass through.

[0040] Through this solution, the sliding connection can adjust the depth position of the bristles 33, which is suitable for heat sinks with different groove depths and has a better cleaning effect; by popping out the pressing pin 321, the sliding adjustment plate 32 is prevented from sliding freely, ensuring safety and effectiveness of use; and by pressing the pressing pin 321, the sliding adjustment plate 32 can continue to slide freely to achieve the function of adjusting the height, which is simple and convenient to use.

[0041] The working mode of this device:
