Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting machines, specifically a sealing structure for a box-type shot blasting machine. Background Technology
[0002] One existing type of shot blasting machine is the box-type shot blasting machine, also known as the hook-type shot blasting machine, such as... Figure 1 As shown in the partial structure, the machine includes a housing. One side of the housing's top plate has a rectangular notch for inserting a hook. Corner-shaped baffles are fixed to the top plates on both sides below the rectangular notch, with gaps between the baffles. The main function of the baffles is to block the high-speed shot from the shot blasting machine during operation, preventing it from being ejected through the rectangular notch. However, in practical application, a defect has been found: the gap between the lower edges of the two baffles is still relatively large, resulting in poor sealing. A small amount of shot and dust can still escape, which is detrimental to maintaining a clean workshop environment. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this utility model provides a sealing structure for a box-type shot blasting machine. This structure can seal the rectangular opening at the top of the box-type shot blasting machine, preventing shot and dust from flying out, thus helping to maintain the workshop environment and effectively solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a box-type shot blasting machine, comprising a rectangular notch for a hook to be inserted into, located on one side of the top plate of the box; corner baffles fixed on both sides of the top plate below the rectangular notch; gaps between the baffles; a sealing element fixed on the inner side of the baffle; the sealing element comprising a fixing plate; the fixing plate being fixed to the upper surface of the lower half of the baffle; a horizontal connecting part fixed at the lower end of the fixing plate; a fixing block fixed at the inner end of the connecting part; a first rectangular groove embedded in the inner side of the fixing block; and a flexible silicone block being adhered and fixed in the first rectangular groove.
[0005] As a preferred technical solution, the inner surfaces of the silicone blocks at the inner ends of the connecting parts are in contact with each other.
[0006] As a preferred technical solution, the fixing plate is fixedly connected to the lower half of the baffle by bolts.
[0007] As a preferred technical solution, the connecting part has an axially penetrating baffle.
[0008] As a preferred technical solution, the first rectangular groove axially passes through the fixing block.
[0009] As a preferred technical solution, the silicone block is in the shape of a cuboid, and the outer side is fixed with a plug block that mates with the first rectangular groove.
[0010] As a preferred technical solution, the inner ends of the front face of the silicone block are inclined toward the inside of the rectangular notch, so that the front face of the silicone block is a sloping surface.
[0011] As a preferred technical solution, the silicone block has a second rectangular groove that extends axially through the center of its inner surface.
[0012] Compared with the prior art, this utility model provides a sealing structure for a box-type shot blasting machine, which has the following beneficial effects:
[0013] 1. This utility model has a horizontal connecting part fixed at the lower end of the fixed plate, and a fixing block is fixed at the inner end of the connecting part. The inner side of the fixing block is embedded with a first rectangular groove. A flexible silicone block is glued and fixed in the first rectangular groove. When in use, the two flexible silicone blocks are in contact with each other. When the hook enters, the silicone blocks can be squeezed apart to both sides where the hook passes. After the hook passes, the silicone blocks return to the squeezed and sealed state. There is only a very small gap at the location of the hook, which can effectively reduce the rate of shot and dust flying out and help maintain the workshop environment.
[0014] 2. This utility model uses a fixing plate to be fixedly connected to the lower half of the baffle by bolts. During use, the fixing plate can be disassembled by bolts, which is convenient for later inspection and maintenance.
[0015] 3. In this utility model, the inner end of the front face of the silicone block is inclined towards the inside of the rectangular notch, so that the front face of the silicone block is inclined. When in use, the inclined surface can guide the hook at the outer port, which is conducive to the insertion of the hook.
[0016] 4. This utility model features a second rectangular groove that extends axially through the center of the inner surface of the silicone block. In use, the second rectangular groove reduces the strength of the silicone block, which facilitates the hook to press the silicone block to both sides and thus facilitates inward sliding.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] like Figures 2 to 4 As shown, a sealing structure for a box-type shot blasting machine includes a rectangular notch 11 for a hook to be inserted into, located on one side of the top plate of the box body 1. Corner baffles 2 are fixedly installed on the top plates of the box body 1 on both sides below the rectangular notch 11. A gap is provided between the baffles 2. A sealing element 3 is fixedly installed on the inner side of the baffles 2. The sealing element 3 includes a fixing plate 31, which is fixed to the upper surface of the lower half of the baffle 2. A horizontal connecting part 33 is fixedly installed at the lower end of the fixing plate 31. A fixing block 34 is fixedly installed at the inner end of the connecting part 33. A first rectangular groove 35 is embedded in the inner side of the fixing block 34. A flexible silicone block 36 is bonded and fixedly installed in the first rectangular groove 35.
[0026] The inner surfaces of the silicone blocks 36 at the inner end of the connecting part 33 are in contact with each other.
[0027] The fixing plate 31 is fixedly connected to the lower half of the baffle 2 by bolts 32 (with front and rear intervals).
[0028] Connecting part 33 axially penetrating baffle 2.
[0029] The first rectangular groove 35 axially passes through the fixing block 34.
[0030] The silicone block 36 is rectangular in shape, and the outer side is fixed with plug-in blocks 361 that mate with the first rectangular groove 35.
[0031] The inner ends of the front face of silicone block 361 are inclined toward the inside of the rectangular notch, making the front face of silicone block 361 beveled.
[0032] In use, two flexible silicone blocks 361 contact each other. When the hook enters, the silicone blocks 361 are squeezed apart to the sides where the hook passes. After the hook passes, the silicone blocks 361 return to a squeezed-to-seal state, with only a very small gap at the location of the hook. This effectively reduces the rate of shot and dust ejection, which is beneficial for maintaining a clean workshop environment. The fixing plate 31 can be removed via bolts 32, facilitating later inspection and maintenance. The inclined surface 362 guides the hook at the outer end, facilitating hook insertion. Example 2
[0033] like Figure 5 As shown, a second rectangular groove 363 is provided at the center of the inner surface of the silicone block 36, which is axially penetrating.
[0034] In use, the second rectangular groove 363 can reduce the strength of the silicone block 36, which is conducive to the hook squeezing the silicone block 36 to both sides and thus facilitating inward sliding.
