Description

Technical Field

[0001] This utility model relates to the field of glove box technology, specifically to a glove fixing mechanism for a glove box. Background Technology

[0002] Traditional glove boxes typically use bolts or simple ring clamps to achieve a seal when securing gloves. These traditional technologies generally suffer from the following drawbacks: (1) They rely on multiple sets of bolts for point-to-point tightening, resulting in low installation efficiency; (2) They lack a dedicated positioning structure for rolled-up gloves, which can easily cause the rolled-up gloves to slip off under negative pressure conditions in the box; (3) Existing clamping devices cannot adaptively adjust the clamping force, and gaps can form due to material deformation after long-term use; (4) Replacing gloves requires complete disassembly of the fixing mechanism, which is complex and damages the sealing environment.

[0003] Therefore, we propose a glove fixing mechanism for a glove box. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides a glove fixing mechanism for a glove box, which overcomes the shortcomings of the prior art. It is reasonably designed, easy to use, and solves the technical problems of low glove changing efficiency, easy glove slippage, and poor installation reliability of traditional glove boxes.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A glove fixing mechanism for a glove box, characterized in that it includes an inner pressure ring, an outer pressure ring, a locking sleeve, and a flange opening structure;

[0009] The inner pressure ring includes a first sleeve body and a first radially outward flange coaxially connected to the rear end of the first sleeve body and extending radially outward;

[0010] The outer pressure ring includes a second sleeve body and a second radially outward flange coaxially connected to the rear end of the second sleeve body and extending radially outward;

[0011] The first sleeve body and the second sleeve body are coaxially arranged and threaded together, and the first radial outer flange and the second radial outer flange cooperate to clamp the side plate of the glove box;

[0012] The second sleeve body is provided with an annular groove that is recessed inward along the radial direction, and the annular groove can accommodate the rolled edge of the glove tail.

[0013] The flange opening structure includes a pressure strip, a drive sleeve, an elastic element, and a locking sleeve;

[0014] Several pressure strips are arranged in an annular groove and distributed in a ring around the second sleeve body. Each pressure strip is slidably arranged along the radial direction of the annular groove, and the rear end of each pressure strip is provided with an inner conical surface.

[0015] The drive sleeve is fitted into the groove, and the front end of the drive sleeve is provided with an outer conical surface that mates with the inner conical surface;

[0016] The elastic element is disposed between the drive sleeve and the rear sidewall of the annular groove. The elastic element is used to drive the drive sleeve to slide towards the pressure strip. The outer conical surface of the drive sleeve and the inner conical surface of the pressure strip cooperate to drive the pressure strip to move outward along the radial direction of the annular groove.

[0017] The locking sleeve is fitted outside the outer pressure ring and threadedly connected to the outer pressure ring. The inner sidewall of the locking sleeve covers the outer opening of the annular groove to prevent the rolled edge from coming off. The locking sleeve moves toward the rear side of the outer pressure ring, causing the drive sleeve to overcome the action of the elastic element and slide away from the pressure bar.

[0018] Furthermore, the locking sleeve includes a third front sleeve portion, a third middle sleeve portion, and a third rear sleeve portion connected sequentially along the axial direction with increasing inner diameters. The gap between the third front sleeve portion and the second sleeve body is smaller than the size of the rolled edge at the end of the glove, the gap between the third middle sleeve portion and the second sleeve body is larger than the size of the rolled edge at the end of the glove, and the third rear sleeve portion is threadedly connected to the second radial flange.

[0019] Furthermore, the outer pressure ring includes an inner conical locking part coaxially connected to the front end of the second sleeve body and contracting radially inward, and the locking sleeve includes an outer conical locking part coaxially connected to the front end of the third front sleeve part and contracting radially inward. The outer conical locking part and the inner conical locking part cooperate to clamp the glove.

[0020] Furthermore, the front sidewall of the annular groove is provided with a front guide groove corresponding to each pressure strip. A guide post is inserted in the front guide groove. Both the front guide groove and the guide post extend radially along the annular groove. A first spring is sleeved on the guide post. The pressure strip includes an arc-shaped strip body and a sliding part extending outward from the front end of the strip body. The sliding part is inserted into the front guide groove and sleeved on the outside of the guide post. Under the action of the first spring, the sliding part slides radially inward along the annular groove. An inner conical surface is provided on the radially inner side of the rear side of the strip body.

[0021] Furthermore, the rear end of the tapered sleeve body of the drive sleeve is coaxially connected to a press-fit flange extending radially outward, and the stepped portion between the third front sleeve portion and the third middle sleeve portion fits against the press-fit flange.

[0022] Furthermore, the rear end of the press-fit flange is coaxially connected to a sleeve guide, which is sleeved on the outside of the second sleeve body.

[0023] (III) Beneficial Effects

[0024] This utility model embodiment provides a glove fixing mechanism for a glove box. It has the following features:

[0025] Beneficial effects:

[0026] 1. Self-adjusting clamping design: The conical mating pressure bar-drive sleeve structure automatically opens the rolled edge of the glove under the action of the elastic element, making it easy for the glove to be quickly removed. The inner conical locking part-outer conical locking part structure clamps the glove, making it easy for the glove to be quickly put on and pressed to seal.

[0027] 2. The rolled edge positioning structure design tightens and accommodates the rolled edge in the annular groove. The locking sleeve is threaded and covers the outer opening of the annular groove to prevent the rolled edge from coming off. The inner conical locking part-outer conical locking part structure clamps the glove at the front end of the rolled edge, reducing the axial pulling force transmitted to one side of the rolled edge during operation, further preventing the rolled edge from coming off.

[0028] 3. Dual adjustment design: The locking sleeve-outer pressure ring threaded connection realizes the adjustment of axial preload, and the locking sleeve stroke controls the radial clamping range, which can be used to adapt to gloves of different thicknesses.

[0029] 4. Quick-release operation design: simply twist the locking sleeve forward to simultaneously open the pressure strip and release the groove seal, completing the glove change in a single action. No tools are required throughout the process, making it convenient and quick. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0067] See attached document Figure 1-6 A glove fixing mechanism for a glove box includes an inner pressure ring 1, an outer pressure ring 2, a locking sleeve 3, and a flange opening structure 4.

[0068] The inner pressure ring 1 includes a first sleeve body 11 and a first radial flange 12 coaxially connected to the rear end of the first sleeve body 11 and extending radially outward;

[0069] The outer pressure ring 2 includes a second sleeve body 21 and a second radial flange 22 coaxially connected to the rear end of the second sleeve body 21 and extending radially outward;

[0070] The first sleeve body 11 and the second sleeve body 21 are coaxially arranged and threaded together. The first radial flange 12 and the second radial flange 22 cooperate to clamp the side plate of the glove box. Preferably, the first sleeve body 11 is provided with external threads, and the second sleeve body 21 is provided with a stepped hole. The large-diameter end of the stepped hole is provided with internal threads. After the first sleeve body 11 and the second sleeve body 21 are threaded together, the small-diameter end of the stepped hole is flush with or basically flush with the hole wall of the first sleeve body 11. In addition, a sealing ring can be embedded in the outer side wall of the first sleeve body 11 and the second sleeve body 21 where they fit with the side plate of the glove box, and a sealing ring can be embedded in the end face of the stepped hole to improve the corresponding sealing effect.

[0071] The outer wall of the second sleeve body 21 is provided with an annular groove 211 that surrounds the surface and extends radially inward, and the annular groove 211 can accommodate the rolled edge of the glove tail.

[0072] The flange opening structure 4 includes a pressure strip 41, a drive sleeve 44, an elastic element, and a locking sleeve 3;

[0073] A plurality of pressure strips 41 are disposed in an annular groove 211 and are distributed in an annular shape around the second sleeve body 21. Each pressure strip 41 is slidably disposed along the radial direction of the annular groove 211. An inner conical surface 4111 is provided on the inner side of the rear end of each pressure strip 41.

[0074] The drive sleeve 44 is fitted in the groove, and the front end of the drive sleeve 44 is provided with an outer conical surface 4411 that mates with the inner conical surface 4111.

[0075] The elastic element is disposed between the drive sleeve 44 and the rear side wall of the annular groove 211. The elastic element is used to drive the drive sleeve 44 to slide towards the pressure strip 41. The outer conical surface 4411 of the drive sleeve 44 and the inner conical surface 4111 of the pressure strip 41 cooperate. When the drive sleeve 44 moves forward along the axial direction, it drives the pressure strip 41 to move outward along the radial direction of the annular groove 211.

[0076] The locking sleeve 3 is sleeved outside the outer pressure ring 2 and threadedly connected to the outer pressure ring 2. The inner sidewall of the locking sleeve 3 covers the outer opening of the annular groove 211 to prevent the rolled edge from coming off. The locking sleeve 3 moves toward the rear side of the outer pressure ring 2, causing the drive sleeve 44 to overcome the action of the elastic element and slide away from the pressure bar 41.

[0077] In this embodiment, the locking sleeve 3 includes a third front sleeve portion 31, a third middle sleeve portion 32, and a third rear sleeve portion 33 connected sequentially along the axial direction with increasing inner diameters. The adjacent portions of the third front sleeve portion 31 and the third middle sleeve portion 32, and the adjacent portions of the third middle sleeve portion 32 and the third rear sleeve portion 33, are connected by a stepped portion or a radial flange, respectively. The gap between the third front sleeve portion 31 and the second sleeve body 21 is smaller than the size of the rolled edge at the end of the glove to prevent the rolled edge from coming off the annular groove 211. The gap between the third middle sleeve portion 32 and the second sleeve body 21 is larger than the size of the rolled edge at the end of the glove. The third rear sleeve portion 33 is threadedly connected to the second radial flange 22. When the locking sleeve 3 is threadedly tightened to the outer pressure ring 2, that is, when the third rear sleeve portion 33 is threadedly tightened to the second radial flange 22, the third front sleeve portion 31 covers part of the opening area of ​​the annular groove 211, further preventing the rolled edge of the glove from coming off.

[0078] In this embodiment, the outer pressure ring 2 includes an inner conical locking part 23 coaxially connected to the front end of the second sleeve body 21 and radially contracting inward. The locking sleeve 3 includes an outer conical locking part 34 coaxially connected to the front end of the third front sleeve part 31 and radially contracting inward. That is, the inner conical locking part 23 and the outer conical locking part 34 are conical structures with a smaller front and larger rear. The outer conical surface of the outer conical locking part 34 and the inner conical surface of the inner conical locking part 23 cooperate to clamp the glove. Specifically, when the locking sleeve 3 moves towards the rear of the outer pressure ring 2 during thread tightening, the gap between the outer conical surface and the inner conical surface 4111 decreases to clamp the glove. Additionally, a silicone layer can be applied to the outer conical surface and the inner conical surface 4111 as needed to prevent the glove from being crushed.

[0079] In this embodiment, the front sidewall of the annular groove 211 is provided with a front guide groove 2111 corresponding to each pressure strip 41. A guide post 42 is inserted into the front guide groove 2111. The guide post 42 passes through the outer top wall of the front guide groove 2111 and is threaded to the inner bottom wall (the end of the guide post 42 can be provided with an internal hexagonal notch for easy screwing). The front guide groove 2111 and the guide post 42 both extend radially along the annular groove 211. A first spring 43 is sleeved on the guide post 42. The strip 41 includes an arc-shaped main body 411 and a sliding part 412 extending outward from the front end of the main body 411. The sliding part 412 is inserted into the front guide groove 2111 and sleeved on the outside of the guide post 42. The two ends of the first spring 43 abut against the top wall of the front guide groove 2111 and the sliding part 412, respectively. Under the action of the first spring 43, the sliding part 412 slides radially inward along the annular groove 211. The radially inner side of the rear part of the strip-shaped main body 411 is provided with an inner conical surface 4111.

[0080] In this embodiment, the rear end of the tapered sleeve body 441 of the drive sleeve 44 is coaxially connected to a press-fit flange 442 extending radially outward, and the stepped portion between the third front sleeve portion 31 and the third middle sleeve portion 32 fits against the press-fit flange 442. Furthermore, the rear end of the press-fit flange 442 is coaxially connected to a sleeve guide portion 443, which is sleeved outside the second sleeve body 21.

[0081] In this embodiment, the elastic element is a second spring 45. The rear end face of the conical sleeve body 441 has an annular front spring groove 4412, and the rear sidewall of the annular groove 211 has an annular rear spring groove 2112. The second spring 45 is sleeved on the second sleeve body 21 and located in the region of the annular groove 211. Both ends of the second spring 45 extend into the front spring groove 4412 and the rear spring groove 2112, respectively. To facilitate the assembly of the drive sleeve 44 and the second spring 45, the outer pressure ring 2 is radially cut into two segments from the rear sidewall of the annular groove 211 and connected as a whole with a single bolt. In other embodiments, if the outer pressure ring 2 is not cut, the drive sleeve 44 can also be axially cut into two halves of a ring and joined together with two pairs of bolts. Correspondingly, multiple second springs 45, front spring grooves 4412, and rear spring grooves 2112 should be provided, arranged in an annular pattern.
