Description

Technical Field

[0001] This utility model belongs to the field of glyph installation technology and relates to a glyph pressing structure. Background Technology

[0002] A Glyd ring consists of a rubber O-ring and a PTFE ring. The O-ring applies force, while the Glyd ring provides a double-acting piston seal. During installation, the Glyd ring needs to be soaked in hot water for a period of time to allow it to expand before installation. This method is relatively safe, but the heating speed may be slow, and the soaking time needs to be carefully controlled according to specific circumstances. Therefore, a Glyd ring press-in structure is required.

[0003] A gearbox sealing glyph installation device disclosed in Chinese patent CN222003277U includes a connecting sleeve, a connecting seat fixedly connected to the connecting sleeve, and multiple movable plates hinged at equal intervals in a ring on the connecting seat. The multiple movable plates are arranged in a frustum-shaped structure. A limit frame is fixedly connected to one side of the connecting sleeve, and a connecting ring is slidably connected inside the limit frame. Multiple support rods are hinged to the connecting ring, and one end of the support rod is hinged to the movable plate. A driving rod is movably connected to the connecting ring. When the driving rod abuts against the connecting ring, it can cause the multiple movable plates to rotate synchronously.

[0004] The Glyd ring installation device uses a movable plate to expand the outer ring, allowing it to slide and retract along the inclined surface of the guide ring towards the connecting sleeve. However, the Glyd ring is in an expanded state on the guide ring, which can cause it to get stuck when sliding. This requires manual assistance to push the Glyd ring, making it inconvenient to use.

[0005] To address the aforementioned problems, this invention proposes a Grady ring press-fit structure. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a Glydeck press-in structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a bushing, a tightening ring is movably sleeved at the bottom of the bushing, a guide post is movably engaged at the top of the bushing, the outer surface of the guide post is an inclined second slope, a Gladger ring is movably arranged on the second slope, and the Gladger ring is movably sleeved on the bushing.

[0008] A spreading pressure ring is provided above the guide post. The spreading pressure ring is movably set on the top of the glyph. A fixing ring is movably sleeved on the outside of the top of the spreading pressure ring. Two return hook posts are symmetrically and fixedly connected to the bottom surface of the fixing ring. The bottom end of the return hook post is movably engaged with the tightening ring.

[0009] Furthermore, the bottom end of the bushing is provided with a positioning groove, and the bottom end of the tightening ring is movably disposed in the positioning groove, with the inner wall of the bottom end of the tightening ring slidingly engaged with the outer surface of the top of the bushing.

[0010] Furthermore, the bushing has a mounting groove at its top, and the Glyd ring is movably disposed inside the mounting groove; the inner wall of the top of the tightening ring is an inclined first slope, which abuts against the Glyd ring.

[0011] Furthermore, the top end of the expanding pressure ring is annular, the outer surface of the top end of the expanding pressure ring is provided with external threads, and the inner wall of the fixing ring is provided with internal threads that are compatible with the external threads.

[0012] Furthermore, the bottom end of the expanding pressure ring consists of several spaced elastic plates, which are arranged at an angle. The bottom ends of the elastic plates slide against the second inclined surface and are in contact with the Gladley ring.

[0013] Furthermore, the outer surface of the tightening ring has two symmetrical slots, and the tightening ring has a slot between the two slots;

[0014] Both of the hook posts have hook-shaped bottom ends. The hook posts are made of elastic material and are movably engaged in the slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The glyph pressing structure is equipped with a fixing ring. The bottom surface of the fixing ring is symmetrically and fixedly connected to two hook posts. After the glyph is placed on the second inclined surface, the fixing ring can be pushed down to make the elastic plate slide on the second inclined surface. Due to the compression of the second inclined surface, the elastic plate opens and pushes the glyph downward to facilitate the glyph sliding on the second inclined surface until the glyph is pushed into the mounting groove. No operator assistance is required to move the glyph, making it convenient to use.

[0017] 2. The glyph pressing structure is equipped with a tightening ring. Before installing the glyph, the tightening ring is first placed on the bottom of the bushing. When the elastic plate pushes the glyph downward, the bottom of the hook post will be engaged in the slot. When the elastic plate is moved upward, the hook post will drive the tightening ring upward. The first inclined surface of the tightening ring will squeeze the glyph and tighten it. This allows the glyph to be installed and retracted in one integrated process, resulting in higher work efficiency.

[0018] 3. The glyph pressing structure has a slot and a groove on the tightening ring. By inserting the bottom end of the return hook into the slot, the tightening ring can be removed from the bushing. After removal, by rotating the fixing ring, the bottom end of the return hook can be rotated into the groove, thereby separating the tightening ring from the return hook, which is convenient for continued operation. The structure is simple and can be used with simple assembly. Attached Figure Description

[0026] 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.

[0027] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: a glyph press-in structure, including a bushing 1, and a tightening ring 2 is movably sleeved at the bottom of the bushing 1.

[0028] The bottom end of the bushing 1 has a positioning groove 101, and the bottom end of the tightening ring 2 is movably disposed within the positioning groove 101. The tightening ring 2 is positioned on the bushing 1 by the support of the positioning groove 101, so that the tightening ring 2 can only slide upwards in the positioning groove 101. The inner wall of the bottom end of the tightening ring 2 is in sliding engagement with the outer surface of the top of the bushing 1.

[0029] The top of the bushing 1 is movably engaged with a guide post 6, the outer surface of which is an inclined second slope 601. This makes the top of the guide post 6 conical, and the diameter of the bottom of the guide post 6 equal to the diameter of the outer surface of the bushing 1.

[0030] A Grady ring 3 is movably mounted on the second inclined surface 601, and the Grady ring 3 is movably fitted onto the bushing 1. The second inclined surface 601 facilitates the smooth sliding of the Grady ring 3 onto the bushing 1.

[0031] The bushing 1 has a mounting groove 102 at its top, and the glyph 3 is movably disposed inside the mounting groove 102.

[0032] A spreading pressure ring 5 is provided above the guide post 6, and the spreading pressure ring 5 is movably positioned on top of the glyph 3. This allows the spreading pressure ring 5 to push the glyph 3 and press it into the bushing 1.

[0033] The top of the pressure ring 5 is annular. The bottom of the pressure ring 5 consists of several spaced elastic plates 501, which are arranged at an angle. The bottom of the elastic plates 501 slides and abuts against the second inclined surface 601, and also abuts against the Glyd ring 3. This allows the elastic plates 501 to move onto the bushing 1 together with the Glyd ring 3 when it is pressed into the Glyd ring 3.

[0034] A retaining ring 4 is movably fitted onto the top of the expansion ring 5. The outer surface of the top of the expansion ring 5 is provided with external threads, and the inner wall of the retaining ring 4 is provided with internal threads that match the external threads. This threaded connection facilitates the connection between the expansion ring 5 and the retaining ring 4, making assembly and disassembly easy.

[0035] The bottom surface of the fixed ring 4 is symmetrically and fixedly connected to two return hook posts 401, and the bottom end of the return hook post 401 is movably engaged with the tightening ring 2.

[0036] Two slots 201 are symmetrically formed on the outer surface of the tightening ring 2, and a slot 202 is formed between the two slots 201. Each slot 202 is located between the two slots 201, and the top of the slot 202 is unobstructed, while the top of the slot 201 is obstructed.

[0037] Both hook posts 401 have hook-shaped bottom ends, and the shape of the bottom ends of the hook posts 401 is adapted to the slots 201. The hook posts 401 are made of elastic material, and the bottom ends of the hook posts 401 are movably engaged in the slots 201. This allows the hook posts 401 to drive the tightening ring 2 to move together through the slots 201.

[0038] The inner wall of the top of the tightening ring 2 is an inclined first slope 203, which abuts against the glyph 3. When the hook post 401 drives the tightening ring 2 to move upward, the first slope 203 will squeeze the glyph 3, tightening the glyph 3.

[0039] Working principle:

[0040] In use, the tightening ring 2 is fitted onto the bushing 1, with the bottom of the tightening ring 2 positioned within the positioning groove 101. The bottom end of the guide post 6 is inserted into the bushing 1, and the glyph 3 is fitted onto the second inclined surface 601. The spreading pressure ring 5 is rotated into the fixing ring 4, so that several elastic plates 501 are positioned between the two return hook posts 401.

[0041] Move the elastic plate 501 directly above the guide post 6, so that the hook post 401 and the slot 201 are aligned vertically. Press down to open the pressure ring 5, so that the bottom end of the elastic plate 501 moves onto the second inclined surface 601.

[0042] The bottom end of the elastic plate 501 presses down on the Glyd ring 3, causing the Glyd ring 3 to slide onto the outer surface of the bushing 1. As the Glyd ring 3 slides downwards, it expands, and as the elastic plate 501 moves downwards, it opens outwards, meaning the bottom ends of the elastic plates 501 move away from each other. This continues until the Glyd ring 3 slides down into the mounting groove 102, at which point it tightens and moves into the mounting groove 102.

[0043] Since the hook post 401 is made of elastic material, when the hook post 401 moves downward, the tightening ring 2 will also open the hook post 401, causing the bottom end of the hook post 401 to open outward.

[0044] When the elastic plate 501 pushes the glyph 3 into the mounting groove 102, the bottom end of the hook post 401 returns to its original state and thus locks into the slot 201.

[0045] Pulling the fixing ring 4 upwards causes the elastic plate 501 and the return hook column 401 to move upwards. The return hook column 401 then moves the tightening ring 2 upwards together through the slot 201.

[0046] When the tightening ring 2 moves upward, the first inclined surface 203 will squeeze the glyph 3, tightening the glyph 3.

[0047] After removing the tightening ring 2 from the guide post 6, the pressure ring 5 is opened and returned to its original state. The fixing ring 4 is rotated horizontally to rotate the bottom end of the hook post 401 from the slot 201 into the slot 202, thus separating the tightening ring 2 from the hook post 401.

[0048] Hold the fixing ring 4 and rotate the spreading pressure ring 5 to separate the fixing ring 4 from the spreading pressure ring 5.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
