Description

Technical Field

[0001] This utility model relates to the field of gun drill housing improvement technology, specifically to a gun drill housing mechanism. Background Technology

[0002] Currently used gun drill housings consist of two symmetrically arranged left and right halves, which are bolted together. The outer surfaces of both halves are smooth and flat. The gun drill's logo is either directly affixed to the left or right half, or printed on it. Because the left and right halves are molded as a single piece, this logo placement means each housing can only use one logo. When different logos need to be applied to the same gun drill, the entire housing must be replaced, which is inconvenient. Utility Model Content

[0003] The technical problem this invention aims to solve is that the existing gun drill housing design is inconvenient for changing logo labels, and this invention provides a new type of gun drill housing mechanism.

[0004] The technical solution of this utility model is as follows: a gun drill housing mechanism, comprising two symmetrically arranged left and right half-shells, a first slot is provided on the left and / or right half-shells, a first cover is snapped and fixed on the first slot, the first cover includes a first side plate and a second side plate, and an intermediate plate connecting the first and second side plates, a first snap is provided on the edge of the first side plate, a second snap is provided on the edge of the second side plate, a first retaining ring and a second retaining ring are provided on both sides of the first slot, the first retaining ring is adapted to the first snap and snapped, the second retaining ring is adapted to the second snap and snapped, an intermediate snap is provided at one end of the intermediate plate, and an intermediate retaining ring adapted to the intermediate snap is provided at one end of the first slot.

[0005] In the above solution, a first slot is provided on the existing drill housing—the left half housing and / or the right half housing, and a first cover is provided in conjunction with it. The marking slot on the first cover can be used to attach markings or inkjet print markings. When the markings need to be replaced, the entire first cover can be replaced without reconfiguring the left half housing and / or the right half housing, making replacement convenient.

[0006] In one possible implementation, the intermediate plate is recessed to provide a labeling groove. The recessed design better accommodates the label compared to a flat or raised design. The segmented design facilitates the fabrication of the labeling groove.

[0007] In one possible implementation, the shape of the label groove is consistent with the shape of the intermediate plate. Here, "consistent shape" refers to the same external shape, not the same size.

[0008] In one possible implementation, both the intermediate buckle and the intermediate retaining ring are located at the end of the intermediate plate near the drill bit of the gun drill. This position is designed to accommodate the structural feature of the first cover, which is composed of the first side plate, the second side plate, and the intermediate plate, having an open end away from the drill bit, thus enabling better fastening and installation of the first cover.

[0009] In one possible implementation, the first cover, composed of the first side plate, the second side plate, and the intermediate plate, has an opening at the end furthest from the drill bit. This opening at the end furthest from the drill bit allows for timely heat dissipation.

[0010] In one possible implementation, both the first side plate and the second side plate are provided with heat dissipation holes. These holes are used to dissipate heat from the internal moving parts at the drill bit tip.

[0011] In one possible implementation, both the left and right halves of the housing are provided with a first slot, and each first slot is provided with a first cover. The two first slots are symmetrically arranged, allowing two logos to be attached.

[0012] In one possible implementation, the middle plate is raised relative to the first side plate and the second side plate. The raised middle plate gives the first cover a more three-dimensional feel, making the design more aesthetically pleasing.

[0013] In one possible implementation, the first and second side plates extend obliquely from both sides of the intermediate plate to form an unfolded structure that can cover a larger area of ​​the drill surface.

[0014] In one possible implementation, the first cover is integrally molded by injection molding. The first cover is a thin-walled structural component with suitable elasticity and shape stability. The injection molding process ensures high overall dimensional accuracy and stable spatial shape.

[0015] The beneficial effects of this utility model are as follows: By separately creating a first slot on the left or right half of the original gun drill housing, and simultaneously adding a first cover, the design logo is separated from the main housing body. This allows for easy replacement of the logo by simply replacing the first cover, without altering the main housing structure. Furthermore, the first cover can be changed in color or shape to suit different design styles, enriching the product's aesthetic appeal. Attached Figure Description

Detailed Implementation

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] This utility model relates to a gun drill housing mechanism, mainly designed to facilitate logo design on the gun drill housing. In existing gun drill housings, the mechanism comprises two symmetrically arranged left half-housing 1 and right half-housing 2, which are connected and fixed by screws. In this application, a first slot 3 is provided on the left half-housing 1 and / or right half-housing 2. A first cover 4 is snap-fitted onto the first slot 3, and a labeling groove 408 is provided on the first cover 4. The labeling groove 408 is located on a middle plate 403 and is recessed to accommodate stickers for different products, ensuring a high degree of sticker adhesion. The shape of the labeling groove 408 is consistent with the shape of the middle plate 403, meaning it is recessed along the edge arc of the middle plate 403. For aesthetic purposes and enhanced functionality, both the left half-shell 1 and the right half-shell 2 are provided with a first slot 3, and each first slot 3 is provided with a first cover 4.

[0020] Specifically, the first cover 4 includes a first side plate 401 and a second side plate 402, and an intermediate plate 403 connecting the first side plate 401 and the second side plate 402. The edges of the first side plate 401 and the second side plate 402 are respectively provided with a first buckle 404 and a second buckle 405. The two sides of the first slot 3 are respectively provided with a first retaining ring 301 and a second retaining ring 302 adapted to the first buckle 404 and the second buckle 405. One end of the intermediate plate 403 is provided with an intermediate buckle 406, and one end of the first slot 3 is provided with an intermediate retaining ring 303 adapted to the intermediate buckle 406. Thus, through the cooperation of the first buckle 404 and the first retaining ring 301, the second buckle 405 and the second retaining ring 302, and the intermediate buckle 406 and the intermediate retaining ring 303, the first cover 4 can be installed and fixed on the left half-shell 1 and the right half-shell 2.

[0021] In addition, the middle plate 403 is raised relative to the first side plate 401 and the second side plate 402. The raised middle plate 403 makes the first cover 4 more three-dimensional, and this design is more aesthetically pleasing.

[0022] The left and right halves of the housing 1 and 2 contain the drive components for the gun drill bit. During operation, these components rotate at high speeds, generating significant heat. Therefore, the end of the first cover 4, composed of the first side plate 401, the second side plate 402, and the middle plate 403, furthest from the drill bit, is open to allow for heat dissipation. Correspondingly, the middle latch 406 and the middle retaining ring 303 are both located at the end of the middle plate 403 closest to the drill bit. Furthermore, to enhance heat dissipation, ventilation holes 407 are provided on both the first and second side plates 401 and 402.
