Description

Technical Field

[0001] The utility model belongs to the technical field of chassis, and in particular relates to a chassis with a locking structure. Background Art

[0002] As a part of computer accessories, the main function of the chassis is to place and fix various computer accessories, and to play a supporting and protective role. For example, the Chinese utility model patent authorized with announcement number CN220105635U is a computer chassis with a shell locking structure. The computer chassis with this structural design has a chassis bayonet clamped by a mounting plate, and no screws are required to tighten it, so that the mounting plate is firmly closed to the right side of the chassis. Therefore, it can be seen that the existing clamping device basically meets people's practical needs, but the following problems still exist.

[0003] When the operator is separating the case body and the cover of the chassis, the operator no longer needs to tighten the bolts to separate or lock the case body and the cover, but the operator may need to pull the buckles set on the cover at the same time, so that the two sets of buckles no longer fix the cover and the case body, thereby separating or locking the case body and the cover. When the operator does not pull the buckles at the same time, the buckles on either side may be stuck on the lock tongue, which may make it impossible to separate the case body and the cover. For this reason, we propose a chassis with a locking structure. Utility Model Content

[0004] The utility model provides a chassis with a locking structure. After the gear rotates, the gear drives the teeth to move through the push plate, so that the teeth pull the lock tongue to separate from the lock groove. When the operator separates the cover plate and the chassis body, it is no longer necessary to pull the buckles on both sides at the same time, thereby improving the convenience of the operator to disassemble or lock the chassis body and the cover plate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chassis with a locking structure, comprising a chassis body and a cover plate, the cover plate being inserted into the opening of the chassis body, and a traction sleeve being fixed in the middle of the cover plate, a gear and teeth being respectively arranged in the middle of the traction sleeve, and the teeth being arranged on both sides of the gear, and the gear passing through the middle of the traction sleeve, a push plate being arranged on one side where the teeth and the gear are in contact with each other and meshing with the gear, a turning handle being inserted into a turning groove being fixed on the surface of the gear, the turning groove being arranged on the cover plate, a lock tongue being fixed at the end of the teeth, and a lock groove being arranged on the surface of the lock tongue.

[0006] Furthermore, the cover plate surface is symmetrically fixed with storage grooves, and a support frame is inserted in the middle of the storage grooves, the ends of the support frames are penetrated by a rotating shaft fixed on the inner wall of the storage groove, a limiting mechanism is arranged between the rotating shaft and the support frame, and a support rod is fixed to the end of the support frame away from the rotating shaft.

[0007] Furthermore, the limiting mechanism includes a limiting groove and a limiting block, the middle of the rotating shaft is provided with a limiting groove, and the middle of the limiting groove is inserted with a limiting block fixed on the inner wall of the support frame.

[0008] Furthermore, the support frames are all configured as rectangular blocks, and the storage slots are all configured as rectangular grooves, and the rectangular grooves configured in the storage slots match the rectangular blocks configured in the support frames.

[0009] Furthermore, a traction rod is passed through the middle of the teeth, and the traction rod is fixed on the inner wall of the traction sleeve, and a waist-shaped hole matching the traction rod is opened on one side of the teeth passed through by the traction rod.

[0010] Furthermore, the surface of the handle is provided with a plurality of groups of wave-shaped grooves.

[0011] The beneficial effects of the utility model are:

[0012] 1. The chassis with a locking structure is provided with a turning handle, a gear, a push plate, teeth, a lock tongue and a lock groove. After the operator turns the turning handle, the turning handle drives the gear to rotate in the traction sleeve, so that the gear drives the teeth to slide in the traction sleeve through the push plate, and when the teeth slide in the traction sleeve, the teeth drive the lock tongue to move, so that the lock tongue is separated from the lock groove, which is convenient for the operator to separate the two groups of lock tongues from the lock grooves at the same time, and it is no longer necessary to pull the buckles on both sides at the same time, thereby improving the convenience of the operator to disassemble or lock the chassis body and the cover.

[0013] 2. The chassis with a locking structure is provided with a support frame, a storage slot and a rotating shaft. After the operator pulls the support frame to move, the support frame rotates in the storage slot through the rotating shaft, and the support frame and the cover plate are placed on the ground. The cover plate is supported by the support frame so that the support frame and the cover plate form a triangle, and the cover plate is placed upright on the ground. This prevents the operator from scratching the surface of the cover plate with debris on the ground when the operator pulls the cover plate after placing the cover plate flat on the ground, thereby improving the safety of the cover plate placed on the ground.

[0028] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] See also Figure 1 - Fig.12A chassis with a locking structure includes a chassis body 1 and a cover plate 2, the cover plate 2 is inserted into the opening of the chassis body 1, and a traction sleeve 3 is fixed in the middle of the cover plate 2, a gear 14 and a tooth 5 are respectively arranged in the middle of the traction sleeve 3, and the tooth 5 is arranged on both sides of the gear 14, and the gear 14 passes through the middle of the traction sleeve 3, and the tooth 5 and the gear 14 are in contact with each other. A push plate 4 that meshes with the gear 14 is opened on one side, and a turning handle 13 inserted in a turning groove 12 is fixed on the surface of the gear 14, and the turning groove 12 is opened on the cover plate 2, and a lock tongue 6 is fixed at the end of the tooth 5, and the surface of the lock tongue 6 is sleeved with a lock groove 7 opened on the inner wall of the chassis body 1. When the operator needs to remove the cover plate 2 from the chassis body 1, the operator holds his hand on the surface of the turning handle 13, and then operates The operator rotates the handle 13 to rotate the handle 13 in the groove 12, and when the handle 13 rotates in the groove 12, the handle 13 drives the gear 14 to rotate in the traction sleeve 3. When the gear 14 rotates, the gear 14 and the push plate 4 engage with each other, so that the gear 14 pulls the teeth 5 through the push plate 4 to slide in the traction sleeve 3, and when the teeth 5 move in the traction sleeve 3, the teeth 5 drive the locking tongue 6 to move, so that the locking tongue 6 moves out of the locking groove 7. When the locking tongue 6 moves out of the locking groove 7, the locking tongue 6 and the locking groove 7 no longer fix the chassis body 1 and the cover plate 2. The operator pulls the cover plate 2 to take the cover plate 2 out of the chassis body 1. When the operator separates the chassis body 1 and the cover plate 2, it is no longer necessary to tighten the bolts and press them multiple times.

[0031] In other embodiments, the cover plate 2 is symmetrically fixed with storage grooves 10, and the middle of the storage grooves 10 is inserted with a support frame 11, and the ends of the support frames 11 are penetrated by a rotating shaft 17 fixed on the inner wall of the storage groove 10, and a limiting mechanism is arranged between the rotating shaft 17 and the support frame 11, and the limiting mechanism includes a limiting groove 15 and a limiting block 16, and the middle of the rotating shaft 17 is provided with a limiting groove 15, and the middle of the limiting groove 15 is inserted with a limiting block 16 fixed on the inner wall of the support frame 11, and the end of the support frame 11 away from the rotating shaft 17 is fixed with a push rod 9. When the cover plate 2 is removed from the chassis body 1, when the cover plate 2 needs to be placed separately, since the push rod 9 is connected to the two groups of support frames 11, after the operator pulls the push rod 9, the push rod 9 drives the two groups of support frames 11 to move together, and the support frame 1 The circular through hole opened on one side of the end portion of the rotating shaft 17 is rotated on the surface of the rotating shaft 17, so that the support frame 11 is rotated in the storage groove 10. The support frame 11 is taken out of the storage groove 10. When the support frame 11 is rotated on the surface of the rotating shaft 17, the limit block 16 fixed on the inner wall of the circular hole opened on one side of the rotating shaft 17 of the support frame 11 slides in the limit groove 15. When the limit block 16 moves to the inner wall on the other side of the limit groove 15, the limit block 16 limits the limit groove 15 to fix the position of the support frame 11. Then the operator places the cover plate 2 and the support rod 9 on the ground, so that the cover plate 2 and the support frame 11 form a triangle with the ground, so that the support frame 11 supports the cover plate 2, which is convenient for the operator to place the cover plate 2 and avoids the cover plate 2 from being damaged after it is placed later.

[0032] In other embodiments, the support frame 11 is configured as a rectangular block, and the storage slot 10 is configured as a rectangular groove. The rectangular groove provided in the storage slot 10 matches the rectangular block provided in the support frame 11. When the rectangular block provided in the support frame 11 matches the rectangular groove provided in the storage slot 10, the surface of the rectangular block provided in the support frame 11 fits with the inner wall of the rectangular groove provided in the storage slot 10, thereby increasing the friction force of the support frame 11 when inserted into the storage slot 10, and facilitating the support frame 11 to be restricted in the storage slot 10.

[0033] In other embodiments, the middle of the teeth 5 is penetrated by a traction rod 8, and the traction rod 8 is fixed on the inner wall of the traction sleeve 3. The side of the teeth 5 penetrated by the traction rod 8 is provided with a waist-shaped hole matching the traction rod 8. When the gear 14 rotates, the gear 14 and the push plate 4 are meshed with each other, and the gear 14 drives the teeth 5 to slide in the traction sleeve 3 through the push plate 4. The waist-shaped hole opened on the side of the teeth 5 penetrated by the traction rod 8 slides on the surface of the traction rod 8, and because the waist-shaped hole opened on the side of the teeth 5 penetrated by the traction rod 8 It matches the traction rod 8. When the tooth 5 drives the waist-shaped hole to slide on the surface of the traction rod 8, the surface of the traction rod 8 and the inner wall of the waist-shaped hole fit together, thereby increasing the stability of the waist-shaped hole sliding on the surface of the traction rod 8, and the waist-shaped hole opened by the tooth 5 slides on the surface of the traction rod 8, so that the traction rod 8 and the waist-shaped hole pull the moving direction of the tooth 5 in the traction sleeve 3, so that when the tooth 5 moves in the traction sleeve 3, the tooth 5 will not shake at will, thereby improving the stability of the tooth 5 sliding in the traction sleeve 3.

[0034] In other embodiments, a plurality of groups of wavy grooves are provided on the surface of the turning handle 13. When the operator pulls the turning handle 13 to rotate in the turning groove 12, after the operator's hand is gripped on the surface of the turning handle 13, the operator's hand and the plurality of groups of wavy grooves on the surface of the turning handle 13 fit together, so that the plurality of groups of wavy grooves on the surface of the turning handle 13 increase the friction force of the operator's hand gripping the surface of the turning handle 13, thereby improving the stability of the operator pulling the turning handle 13 to rotate in the turning groove 12.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
