[0030] As is known from the background art, during the installation of gas springs, it is usually necessary to use an installation fixture to compress the total length of the gas spring from its free length to a preset length. After the gas spring is installed, the installation structure is removed so that the gas spring can function properly. The above operations not only make the gas spring installation process cumbersome, but also require the additional design of installation fixtures to assist in the gas spring installation.
[0031] To solve the above-mentioned technical problems, this utility model provides a gas spring mounting structure for connecting a gas spring to an opening and closing mechanism. The first end of the gas spring is connected to the housing of the opening and closing mechanism. The gas spring mounting structure includes: a first support member having a first end face and a first hole therein, which is used to connect to the second end of the gas spring; a second support member having a second end face opposite to the first end face and a second hole corresponding to the first hole therein, which is used to connect to the cover of the opening and closing mechanism; and a first threaded fastener embedded in the second and first support members through the second and first holes, for disassembling and locking the first and second support members. The first threaded fastener increases the gap between the second and first support members during disassembly and decreases the gap during locking.
[0032] The gas spring mounting structure disclosed in this embodiment includes a first threaded fastener, which is embedded in the second support member and the first support member through the second hole and the first hole. The first threaded fastener is used to disassemble and lock the first and second support members. It also increases the gap between the second and first support members during disassembly and decreases the gap during locking. Because the first threaded fastener increases the gap between the second and first support members during disassembly and decreases the gap during locking, the gas spring can be gradually pre-tightened during installation onto the opening / closing mechanism until the preset pre-tightening force requirement is met. Furthermore, since the gas spring and the gas spring mounting structure are integrated, no additional gas spring mounting fixture is needed. This avoids the need to pre-tighten the gas spring before installation, thus preventing the impact of the tolerances of the gas spring mounting fixture and the gas spring on the installation accuracy, thereby improving installation accuracy and reducing assembly complexity.
[0033] To make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] Figure 1 This is a schematic diagram of one embodiment of the gas spring mounting structure of this utility model. Figure 2 This is a schematic diagram of the gas spring mounting structure of this utility model in the retracted state. Figure 3 This is a schematic diagram of one embodiment of the gas spring connection structure of this utility model. Figure 4 This is a schematic diagram of the gas spring of the gas spring connection structure of this utility model.
[0035] refer to Figures 1 to 4 and in conjunction with references Figures 5 to 6 In this embodiment, the gas spring mounting structure 100 is used to connect the gas spring 200 and the opening / closing mechanism 10. The first end 201 of the gas spring 200 is used to connect to the housing 11 of the opening / closing mechanism 10. The gas spring mounting structure includes: a first support member 110, which has a first end face 111 and a first hole (not shown) in the first end face 111, and is used to connect to the second end 202 of the gas spring 200; and a second support member 120, which has a second end face 121, which is opposite to the first end face 111, and has a hole in the second end face 121 that connects to the second end 202 of the gas spring 200. The second hole (not shown) is corresponding to the first hole. The second support member 120 is used to connect with the cover 12 of the opening and closing mechanism 10. The first threaded fastener 130 is embedded in the second support member 120 and the first support member 110 through the second hole and the first hole. It is used to realize the disassembly and locking of the first support member 110 and the second support member 120. The first threaded fastener 130 is used to increase the gap 140 between the second support member 120 and the first support member 110 during disassembly and to reduce the gap 140 between the second support member 120 and the first support member 110 during locking.
[0036] It should be noted that, in order to clearly show the gas spring mounting structure, Figure 3 The third hole is omitted.
[0037] The first support member is used to connect to the second end 202 of the gas spring 200 so that the gas spring mounting structure 100 is connected to the gas spring 200.
[0038] As an example, the first support member 110 is in the shape of a cuboid. In other embodiments, the first support member may also be in the shape of a cylinder or other suitable shape.
[0039] As another example, the first support member 110 is a stainless steel first support member.
[0040] The first hole provides space for setting the first threaded fastener 130.
[0041] In this embodiment, one of the first hole and the second hole is a threaded hole, and the other is a smooth hole.
[0042] The threaded hole is used to mate with the first threaded fastener 130.
[0043] The aperture is used for the first threaded fastener 130 to pass through so that the first threaded fastener 130 mates with the threaded hole; it is understood that the aperture is a through hole.
[0044] Specifically, the threaded hole is a blind hole. 。
[0045] It should be noted that the first hole is a threaded hole; correspondingly, the first threaded fastener 130 is inserted into the first hole via the second hole.
[0046] In this embodiment, the number of the first hole is at least three, and the second hole and the first threaded fastener 130 correspond one-to-one with the first hole.
[0047] It is understandable that the number of the second hole and the first threaded fastener 130 is at least three, which helps to reduce the force on a single first threaded fastener 130 during the locking process, thereby making the first threaded fastener 130 more stable when locked.
[0048] As an example, the number of the first holes is four. Correspondingly, the number of the second holes and the first threaded fastener 130 is also four. In other embodiments, the number of the first holes may also be five, six, etc.
[0049] Specifically, the projections of the multiple first holes on the first end face 111 are distributed in an equal-angle ring around the center of the first end face 111. Correspondingly, the projection patterns of the first threaded fasteners 130 on the first end face 111 are also distributed in an equal-angle ring around the center of the first end face 111. This makes the force required to rotate each of the first threaded fasteners more consistent during the locking process, thereby helping to reduce the difficulty of locking each of the first threaded fasteners 130.
[0050] In this embodiment, the second end 202 of the gas spring 200 has a connector 203 (such as...). Figure 6 (As shown); the first support member 110 has an interface on its side that is adapted to the connector, the interface being used to connect with the connector 203 so that the first support member 110 is connected to the second end 202 of the gas spring 200, which helps to reduce the difficulty of connecting the first support member 110 to the second end 202 of the gas spring 200.
[0051] The side of the first support member 110 refers to the surface of the first support member 110 that is perpendicular to the first end face 111.
[0052] As an example, the connector 203 is a screw portion. Correspondingly, the interface is a threaded hole. In another embodiment, the connector 203 is a rod portion. Correspondingly, the interface is a through hole, and the rod portion is interference-fitted with the through hole. In other embodiments, the connector and interface may also be other suitable connection methods.
[0053] The second support member 120 is used to connect with the cover 12 of the opening and closing mechanism 10 so that the gas spring mounting structure 100 is connected to the opening and closing mechanism 10.
[0054] As an example, the second support member 120 is a stainless steel second support member.
[0055] In this embodiment, a groove 128 is provided in the side wall of the second support member 120 near the second end face 121. The groove 128 communicates with the second hole so that the first threaded fastener 130 passes through the groove 128 and through the second hole.
[0056] The groove 128 is used to provide space for the head of the first threaded fastener 130.
[0057] In this embodiment, the second support member 120 includes a first fixing part 123, a second fixing part 124, and a connecting part 125 connecting the first fixing part 123 and the second fixing part 124; the first fixing part 123 has a second end face 121; the second fixing part 124 is used to connect with the lid 12 of the opening and closing mechanism 10; the cross-sectional area of the connecting part 125 near the first fixing part 123 is smaller than the cross-sectional area of the first fixing part 123, and the cross-sectional area of the connecting part 125 near the second fixing part 124 is smaller than the cross-sectional area of the second fixing part 124, which helps to reduce the volume of the connecting part 125, and correspondingly helps to save the material required to manufacture the connecting part 125, thereby helping to save the material of the second support member 120.
[0058] In this embodiment, as Figure 3 As shown, at least one sidewall of the connecting portion 125 is stepped. The stepped sidewall includes a first vertical portion 1251, a second vertical portion 1252, and a horizontal portion 1253 connecting the first vertical portion 1251 and the second vertical portion 1252. The first vertical portion 1251 and the second vertical portion 1252 extend along the length direction of the connecting portion 125, and the first vertical portion 1251 is recessed inward relative to the second vertical portion 1252.
[0059] It is understood that the inwardly recessed first vertical portion 1251, the horizontal portion 1253, and the first fixing portion 123 can form a groove 128, or the inwardly recessed first vertical portion 1251, the horizontal portion 1253, and the second fixing portion 124 can form a groove 128.
[0060] At least one sidewall of the connecting portion 125 is stepped to facilitate the installation of the first threaded fastener 130.
[0061] As an example, when the connecting part 125 is a cuboid with a groove, one side wall of the connecting part 125 may be stepped, or two side walls of the connecting part 125 may be stepped, or three side walls of the connecting part 125 may be stepped, or all four side walls of the connecting part 125 may be stepped.
[0062] As another example, when the connecting part is a cylinder with a groove, some of the sidewalls of the connecting part are stepped, or all of the sidewalls of the connecting part are stepped.
[0063] In this embodiment, the second support member further includes a reinforcing rib 126. One end of the reinforcing rib 126 is connected to the horizontal portion 1253, and the other end is connected to the first fixing portion 123 or the second fixing portion 124 facing the horizontal portion 1253. The sidewall of the reinforcing rib 126 is connected to the first vertical portion 1251. This helps to save material on the connecting portion 125 while improving the firmness between the first fixing portion 123 and the second fixing portion 124, thereby also improving the firmness of the second support member 120 and correspondingly improving the reliability of the second support member 120.
[0064] In other embodiments, the other end of the reinforcing rib is connected to a second fixing part facing the horizontal portion.
[0065] When the connecting part 125 is a cuboid with a groove, the reinforcing rib is a cuboid and the side of the reinforcing rib is rectangular.
[0066] When the connecting part is a cylinder with a groove, the reinforcing rib can be a cuboid or a fan-shaped ring; correspondingly, the side of the reinforcing rib is a rectangle or an arc-shaped surface.
[0067] As an example, the number of the reinforcing ribs 126 is one.
[0068] As another example, the number of reinforcing ribs can also be multiple. On a projection plane parallel to the second end face, multiple reinforcing ribs are arranged around the center of the connecting portion. Specifically, on a projection plane parallel to the second end face, multiple reinforcing ribs are distributed in a ring at equal angles around the center of the connecting portion.
[0069] In this embodiment, the second fixing part 124 exposed by the connecting part 125 is provided with a third hole (not shown in the figure). The third hole is a mounting hole for connecting the second support member 120 and the box cover 12, so that the second support member 120 and the box cover 12 can be detachably connected by the second threaded fastener 300 passing through the third hole.
[0070] The third hole serves as the first mounting hole.
[0071] As an example, the third hole is a smooth hole. In other embodiments, the third hole is a threaded hole.
[0072] In other embodiments, the second support member and the box cover can also be connected by a non-removable connection method, such as welding.
[0073] Since the first threaded fastener 130 is used to increase the gap 140 between the second support member 120 and the first support member 110 during disassembly and to reduce the gap between the second support member 120 and the first support member 110 during locking, the gas spring 200 can be gradually pre-tightened during the process of installing the gas spring 200 onto the opening and closing mechanism 10 until the preset pre-tightening force requirement is reached. Moreover, since the connection structure formed by the gas spring and the gas spring mounting structure is an integral design, no additional gas spring mounting fixture is required. Therefore, the operation of pre-tightening the gas spring before installation is avoided, which also avoids the impact of the superposition of tolerances between the gas spring mounting fixture and the gas spring on the installation accuracy. This improves the installation accuracy and reduces the assembly complexity.
[0074] like Figure 4 As shown, the length of the gas spring 200 satisfies:
[0075] x = L × sinθ;
[0076] (x2+x1)=(L N -Δ)×sinθ;
[0077] x2 = L × sinθ - x1;
[0078] x2=(L N -Δ)×sinθ-x1;
[0079] Where L is the length of the gas spring, x is the effective horizontal distance between the gas spring and the connection point A of the first support member 110, x1 is the effective horizontal distance of the second support member 120, x2 is the horizontal distance from the connection point A of the first support member 110 to the second support member 120, and θ is the angle between the gas spring and the vertical direction. N Δ is the free length of the gas spring, that is, the length of the gas spring in its uncompressed state, and Δ is the compression of the gas spring.
[0080] Here, the horizontal direction refers to the direction parallel to the extension direction of the second support member, and the vertical direction refers to the direction perpendicular to the horizontal direction.
[0081] From the above relationship and Figure 4 As can be seen, when x2 decreases, that is, when the effective distance from the connection point A of the first support member 110 to the second support member 120 in the horizontal direction decreases, that is, when the gap between the second support member 120 and the first support member 110 decreases, the compression amount Δ of the gas spring will increase accordingly, and the length L of the gas spring will decrease accordingly, thereby maintaining a stable structure between the gas spring mounting structure 100 and the gas spring 200.
[0082] Therefore, the gap between the second support member 120 and the first support member 110 can be reduced during the locking process by the first fastener 130, thereby gradually pre-tightening the gas spring 200 until the preset pre-tightening force requirement is reached.
[0083] In this embodiment, one of the first hole and the second hole is a threaded hole, and the other is a smooth hole. Correspondingly, the first threaded fastener 130 is a screw, which is inserted into the threaded hole through the smooth hole. The threaded engagement has high reliability and is not prone to loosening, thereby improving the reliability of the mechanical connection between the first support member 110 and the second support member 120.
[0084] In other embodiments, the first threaded fastener may further include a bolt and a nut. Accordingly, both the first and second holes are smooth holes.
[0085] In this embodiment, the first threaded fastener 130 includes a head (not shown) and a threaded portion (not shown). The head is disposed in the groove 128, and the threaded portion passes through the groove, penetrates the second hole, and is threadedly connected to the first hole, which helps to reduce the difficulty of connecting the threaded portion to the threaded first hole (i.e., the threaded hole).
[0086] In other embodiments, the first support member further has a third end face disposed opposite to the first end face, and the head may also be disposed on the third end face.
[0087] Figure 5 This is a schematic diagram of one embodiment of the gas spring connection structure of this utility model. Figure 6 This is a schematic diagram of the gas spring of the gas spring connection structure of this utility model.
[0088] refer to Figure 5 and Figure 6 and in conjunction with references Figures 1 to 2 In this embodiment, the gas spring connection structure 20 is used to connect the housing 11 and the cover 12 of the opening and closing mechanism 10. The gas spring connection structure 20 includes: a gas spring 200, the first end 201 of which is connected to the housing 11 of the opening and closing mechanism 10; and a gas spring mounting structure 100, the first support member 110 of which is connected to the second end 202 of the gas spring 200, and the second support member 120 of which is connected to the cover 12.
[0089] Since the first threaded fastener 130 of the gas spring mounting structure 100 is used to increase the gap 140 between the second support member 120 and the first support member 110 during disassembly, and to reduce the gap between the second support member 120 and the first support member 110 during locking, the gas spring 200 can be gradually pre-tightened during the process of installing the gas spring 200 onto the opening and closing mechanism 10, that is, during the connection process between the gas spring connecting structure 20 and the opening and closing mechanism 10, until the preset pre-tightening force requirement is reached; moreover, since the gas spring and the gas spring mounting structure constitute the gas spring connecting structure 20 as an integral design, no additional gas spring mounting fixture is required, thus avoiding the operation of pre-tightening the gas spring before installation, thereby avoiding the influence of the superposition of tolerances between the gas spring mounting fixture and the gas spring on the installation accuracy, thereby improving the installation accuracy and correspondingly reducing the assembly complexity.
[0090] Furthermore, the gas spring connection structure 20 includes the gas spring 200 and the gas spring mounting structure 100. Compared with the operation of pre-tightening the gas spring before installation, it is beneficial to avoid the inability to install, replace or repair the gas spring 200 due to the lack of a jig for compressing the gas spring when installing, replacing or repairing the gas spring 200, thereby improving the convenience of installing and maintaining the gas spring connection structure 20.
[0091] In this embodiment, when the gas spring 200 is in a pre-tensioned state, the first end face 111 and the second end face 121 are in contact, and the first end face 111 and the second end face 121 can limit each other, thereby enabling the first support member 110 and the second support member 120 to be tightly connected.
[0092] In this embodiment, the second end 202 of the gas spring 200 has a connector 203 (such as...). Figure 6 (as shown); the first support member 110 has an interface (not shown) on its side that is adapted to the connector. The interface is used to connect with the connector 203 so that the first support member 110 can be connected to the second end 202 of the gas spring 200, which helps to reduce the difficulty of connecting the first support member 110 to the second end 202 of the gas spring 200.
[0093] The side of the first support member 110 refers to the surface of the first support member 110 that is perpendicular to the first end face 111.
[0094] As an example, the connector 203 is a threaded portion. Correspondingly, the interface is a threaded hole. In another embodiment, the connector is a smooth portion. Correspondingly, the interface is a smooth hole, and the smooth portion and the smooth hole are interference-fitted. In other embodiments, the connector and interface may also be other suitable connection methods.
[0095] It should be noted that the first end 201 of the gas spring 200 also has a connector 203.
[0096] In this embodiment, the gas spring 200 includes a nitrogen spring or an air spring.
[0097] It should be noted that the steps for installing the gas spring connection structure 20 include: Step 1: Connecting the connector 203 of the first end 201 of the gas spring 200, i.e., the screw portion of the first end 201, to the housing 11. Step 2: Connecting the second fixing portion 124 of the second support member 120 to the housing cover 12, for example, by using the second threaded fastener 300 to connect the second fixing portion 124 to the housing cover 12. Step 3: Connecting the connector 203 of the second end 202 of the gas spring 200 to the first support member 110. Step 4: With the first support member 110 connected to the connector of the second end 202 of the gas spring 200, and with the second fixing portion 124 of the second support member 120 connected to the housing cover 12, opening the housing cover 12 so that the housing cover 12 and the housing 11 form a certain angle, aligning the first hole with the second hole, thereby allowing the first threaded fastener 130 to connect the first support member 110 and the second support member 120. Step 5: Tighten the first threaded fastener 130 one by one in sequence to lock the first threaded fastener 130.
[0098] Understandably, the order of execution of steps 1, 2, and 3 can be adjusted as needed. For example, after executing step 1, execute step 2 first and then step 3, or after executing step 1, execute step 3 first and then step 2, or after executing step 2, execute step 1 first and then step 3, or after executing step 2, execute step 3 first and then step 1, etc.
[0099] As an example, when there are four first threaded fasteners 130, the steps of gradually tightening the first threaded fasteners 130 sequentially include: rotating one of the first threaded fasteners 130 to a preset number of turns, that is, rotating the first first threaded fastener 130 to a preset number of turns, first rotating the second first threaded fastener 130, which is diagonally opposite to the first first threaded fastener 130, to a preset number of turns, then rotating any one of the remaining two first threaded fasteners 130 to a preset number of turns, and finally rotating the fourth first threaded fastener 130 to a preset number of turns. After completing the above operation, the above steps are repeated until all four first threaded fasteners 130 are completely tightened.
[0100] Specifically, with all four first threaded fasteners 130 fully locked, the first end face 111 is in contact with the second end face.
[0101] It should be noted that for a detailed description of the gas spring mounting structure, please refer to the detailed description of the foregoing embodiments, which will not be repeated in this embodiment.
[0102] Accordingly, this utility model also provides a device with an opening and closing mechanism. Figure 7 This is a schematic diagram of an embodiment of the device with an opening and closing mechanism of this utility model in the open state. Figure 8 This is a schematic diagram of the structure of an embodiment of the device with an opening and closing mechanism in the closed state.
[0103] In this embodiment, the device 1 with the opening and closing mechanism includes: an opening and closing mechanism 10, which includes a housing 11 and a cover 12 rotatably connected; and a gas spring connection structure 20 of the present invention, wherein the first end 201 of the gas spring 200 is connected to the housing 11, and the second support member 120 is connected to the cover 12.
[0104] The lid 12 is rotatably connected to the body 11 to enable the opening and closing of the opening and closing mechanism 10.
[0105] Since the first threaded fastener 130 of the gas spring mounting structure 100 is used to increase the gap 140 between the second support member 120 and the first support member 110 during disassembly, and to reduce the gap between the second support member 120 and the first support member 110 during locking, the gas spring 200 can be gradually pre-tightened during the process of installing the gas spring 200 onto the opening and closing mechanism 10, that is, during the connection process between the gas spring connecting structure 20 and the opening and closing mechanism 10, until the preset pre-tightening force requirement is reached; moreover, since the gas spring and the gas spring mounting structure constitute the gas spring connecting structure 20 as an integral design, no additional gas spring mounting fixture is required, thus avoiding the operation of pre-tightening the gas spring before installation, thereby avoiding the influence of the superposition of tolerances between the gas spring mounting fixture and the gas spring on the installation accuracy, thereby improving the installation accuracy and correspondingly reducing the assembly complexity.
[0106] Furthermore, the gas spring connection structure 20 includes the gas spring 200 and the gas spring mounting structure 100. Compared with the operation of pre-tightening the gas spring before installation, it is beneficial to avoid the inability to install, replace or repair the gas spring 200 due to the lack of a jig for compressing the gas spring when installing, replacing or repairing the gas spring 200, thereby improving the convenience of installing and maintaining the gas spring connection structure 20.
[0107] In this embodiment, the second support member 120 includes a first fixing part 123, a second fixing part 124, and a connecting part 125 connecting the first fixing part 123 and the second fixing part 124; the first fixing part 123 has a second end face 121; the second fixing part 124 is used to connect with the lid 12 of the opening and closing mechanism 10; the cross-sectional area of the connecting part 125 near the first fixing part 123 is smaller than the cross-sectional area of the first fixing part 123, and the cross-sectional area of the connecting part 125 near the second fixing part 124 is smaller than the cross-sectional area of the second fixing part 124; a third hole (not shown) is provided in the second fixing part 124 exposed by the connecting part 125; the third hole is a first mounting hole for realizing the connection between the second support member 120 and the lid 12. The cover 12 is provided with a fourth hole (not shown); the fourth hole is a second mounting hole for connecting the second support member 120 and the cover 12; the device 1 further includes a second threaded fastener 300, which is embedded in the second fixing part 124 and the cover 12 through the third hole and the fourth hole, so that the second support member 120 is connected to the cover 12.
[0108] The second fixing part 124 is provided with a third hole, and the box cover 12 is provided with a fourth hole. The second threaded fastener 300 is embedded in the second fixing part 124 and the box cover 12 through the third hole and the fourth hole, so as to facilitate the detachable connection between the second support member 120 and the box cover 12.
[0109] Specifically, the fourth hole is a threaded hole, the third hole is a smooth hole and a through hole, and the second threaded fastener 300 is a screw, which is inserted into the fourth hole through the third hole.
[0110] More specifically, the fourth hole is a blind hole.
[0111] In other embodiments, the third hole is a threaded hole, the fourth hole is a smooth hole, and the second threaded fastener (screw) is inserted into the third hole via the fourth hole.
[0112] In other embodiments, the second threaded fastener may also include a bolt and a nut. Accordingly, the third and fourth holes are both smooth holes.
[0113] It should be noted that for a detailed description of the gas spring connection structure, please refer to the detailed description of the foregoing embodiments, which will not be repeated in this embodiment.
[0114] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
