Description

Technical Field

[0001] This invention belongs to the field of media system pipeline connection technology, and in particular relates to a plug-in plate connection structure with constraint function and its fixing device. Background Technology

[0002] In media system pipelines, quick couplings are often used to facilitate quick connection and disconnection of pipelines. Quick couplings are widely used because they are convenient and quick to connect. However, in densely packed pipeline locations with confined spaces, connecting each pipeline one by one has the disadvantages of high probability of misconnection and low connection efficiency.

[0003] To overcome the aforementioned technical shortcomings, the existing solution involves designing a plug-in plate with multiple pipeline interfaces, vertically mounting it within the slide rail of a fixing device on the base frame. This allows for easy insertion and removal, enabling quick replacement. External pipelines are connected to the pipeline interfaces on the plug-in plate. A docking plate with multiple pipeline interfaces is also vertically mounted on the equipment, connecting the equipment's pipelines to these interfaces. During horizontal installation, the pipeline interfaces on the docking plate can precisely and quickly connect to the interfaces on the plug-in plate, achieving rapid pipeline connection. However, while the plug-in plate is constrained horizontally by the slide rail, it lacks vertical constraint. This can lead to situations where the plug-in plate cannot be properly installed during pipeline connection, affecting the precise and rapid connection. Therefore, there is an urgent need to develop a plug-in plate fixing device that provides vertical constraint without hindering quick replacement. Summary of the Invention

[0004] The main objective of this invention is to propose a plug-in plate connection structure with constraint function and its fixing device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A plug-in plate connection structure with constraint function includes a locking device and a connecting plate, wherein the locking device is disposed on a base and the connecting plate is disposed on the plug-in plate;

[0007] The locking device includes a mounting plate, on the sides of which an upper base and a lower base are fixed respectively. A first elastic guide is fixed on the lower base near the mounting plate, and a closed guide plate is fixed on the top of the first elastic guide. A second elastic guide is fixed on the upper base near the closed guide plate, and a follower guide plate is fixed on the bottom of the second elastic guide. A third elastic guide is fixed on the lower base near the follower guide plate, and a baffle is fixed on the top of the third elastic guide.

[0008] The closed guide plate has a first semi-circular groove on its side and a through hole on its follower guide plate. In the initial state, the first semi-circular groove is aligned with the through hole and a steel ball is placed inside the first semi-circular groove and the through hole. The third elastic guide is in its natural state, so that the baffle covers the through hole and abuts against the steel ball. Half of the steel ball is located in the first semi-circular groove and the other half is located in the through hole. The closed guide plate and the follower guide plate are connected as a whole by the steel ball. At this time, the elastic force of the second elastic guide is greater than the elastic force of the first elastic guide, and the follower guide plate abuts against the lower base.

[0009] The connecting plate has a second semi-circular groove. When the connecting plate is connected to the locking device, the connecting plate presses the baffle vertically downward until the second semi-circular groove is aligned with the through hole. The closed guide plate moves upward under the elastic force of the first elastic guide body and pushes the steel ball to move into the second semi-circular groove. The connecting plate and the follower guide plate are connected as a whole by the steel ball. At this time, the elastic force of the second elastic guide body is greater than the elastic force of the third elastic guide body.

[0010] Preferably, the closed guide plate, the follower guide plate, and the baffle are all strip-shaped rectangular plate structures with a groove at one end. The first elastic guide, the second elastic guide, and the third elastic guide are all springs. One end of the spring is fixed to the lower base or the upper base, and the other end is fixedly connected to the bottom of the groove of the closed guide plate, the follower guide plate, and the baffle.

[0011] Preferably, the diameter of the through hole is equal to the diameter of the steel ball, and the length is equal to the radius of the steel ball.

[0012] Preferably, both the longitudinal slot and the first transverse slot are located in the exact center of the upper column.

[0013] Preferably, the length of the upper base is shorter than the length of the lower base.

[0014] A mounting plate fixing device with constraint function includes the mounting plate connecting structure described in any one of the above claims, and further includes a fixing device and a mounting plate;

[0015] The fixing device includes a base plate, and lower columns are fixed to the top of both ends of the base plate. An upper column is fixed to the top of the two lower columns. The upper column has a longitudinal slot and a first transverse slot through it, and the lower column has a second transverse slot through it. The first transverse slot and the second transverse slot are connected to each other.

[0016] Both ends of the longitudinal slot are equipped with locking devices. The mounting plate is fixedly connected to the upper column, and the lower base and the upper base are embedded in the longitudinal slot.

[0017] The insert plate includes an intermediate plate, with slide plates fixed at both ends of the intermediate plate and connecting plates fixed on both sides of the top of the slide plates. Two of the locking devices form a cross groove with the upper column for inserting the insert plate.

[0018] Preferably, the upper and lower columns are fixed with side plates.

[0019] This invention provides a plug-in plate connection structure with constraint function and its fixing device, which has the following beneficial effects;

[0020] This invention provides vertical constraint for the insert plate without affecting its rapid replacement. Attached Figure Description

[0031] Examples, such as Figure 1-2 As shown, a plug-in plate connection structure with constraint function includes a locking device 3 and a connecting plate 1.2. The locking device 3 is disposed on the fixing device 2, and the connecting plate 1.2 is disposed on the plug-in plate 1.

[0032] The locking device 3 includes a mounting plate 3.6. An upper base 3.4 and a lower base 3.5 are fixed to the sides of the mounting plate 3.6. A first elastic guide 3.3.1 is fixed to the lower base 3.5 near the mounting plate 3.6. A closed guide plate 3.3 is fixed to the top of the first elastic guide 3.3.1. A second elastic guide 3.2.1 is fixed to the upper base 3.4 near the closed guide plate 3.3. A follower guide plate 3.2 is fixed to the bottom of the second elastic guide 3.2.1. A third elastic guide 3.1.1 is fixed to the lower base 3.5 near the follower guide plate 3.2. A baffle 3.1 is fixed to the top of the third elastic guide 3.1.1.

[0033] The closed guide plate 3.3 has a first semi-circular groove 3.3.2 on its side, and the follower guide plate 3.2 has a through hole 3.2.2. In the initial state, the first semi-circular groove 3.3.2 and the through hole 3.2.2 are aligned, and a steel ball 3.2.3 is placed inside the first semi-circular groove 3.3.2 and the through hole 3.2.2. The third elastic guide 3.1.1 is in a natural state, so that the baffle 3.1 covers the through hole 3.2.2 and abuts against the steel ball 3.2.3. Half of the steel ball 3.2.3 is located in the first semi-circular groove 3.3.2, and the other half is located in the through hole 3.2.2. The closed guide plate 3.3 and the follower guide plate 3.2 are connected as a whole by the steel ball 3.2.3. At this time, the elastic force of the second elastic guide 3.2.1 is greater than the elastic force of the first elastic guide 3.3.1, and the follower guide plate 3.2 abuts against the lower base 3.5.

[0034] The connecting plate 1.2 has a second semi-circular groove 1.3. When the connecting plate 1.2 is connected to the locking device 3, the connecting plate 1.2 presses the baffle 3.1 vertically downward until the second semi-circular groove 1.3 is aligned with the through hole 3.2.2. The closed guide plate 3.3 moves upward under the elastic force of the first elastic guide 3.3.1, while pushing the steel ball 3.2.3 to move into the second semi-circular groove 1.3. The connecting plate 1.2 and the follower guide plate 3.2 are connected as a whole by the steel ball 3.2.3. At this time, the elastic force of the second elastic guide 3.2.1 is greater than the elastic force of the third elastic guide 3.1.1.

[0035] In one specific embodiment, the closed guide plate 3.3, the follower guide plate 3.2, and the baffle 3.1 are all strip-shaped rectangular plate structures with a groove at one end. The first elastic guide 3.3.1, the second elastic guide 3.2.1, and the third elastic guide 3.1.1 are all springs. One end of the spring is fixed to the lower base 3.5 or the upper base 3.4, and the other end is fixedly connected to the bottom of the groove of the closed guide plate 3.3, the follower guide plate 3.2, and the baffle 3.1.

[0036] In one specific embodiment, the diameter of the through hole 3.2.2 is equal to the diameter of the steel ball 3.2.3, and the length is equal to the radius of the steel ball 3.2.3.

[0037] In one specific embodiment, the longitudinal slot 2.5 and the first transverse slot 2.6 are both located in the middle of the upper column 2.1.

[0038] In one specific embodiment, the length of the upper base 3.4 is shorter than the length of the lower base 3.5.

[0039] A plug-in plate fixing device with constraint function includes the plug-in plate connecting structure described in any one of the above claims, and further includes fixing device 2 and plug-in plate 1;

[0040] The fixing device 2 includes a base plate 2.3, with lower columns 2.2 fixed to the top of both ends of the base plate 2.3. An upper column 2.1 is fixed to the top of the two lower columns 2.2. The upper column 2.1 has a longitudinal slot 2.5 and a first transverse slot 2.6 through it, and the lower column 2.2 has a second transverse slot 2.7 through it. The first transverse slot 2.6 and the second transverse slot 2.7 are connected to each other.

[0041] Locking devices 3 are provided at both ends of the longitudinal slot 2.5. The mounting plate 3.6 is fixedly connected to the upper column 2.1. The lower base 3.5 and the upper base 3.4 are embedded in the longitudinal slot 2.5.

[0042] The insert plate 1 includes an intermediate plate 1.4, with slide plates 1.1 fixed at both ends of the intermediate plate 1.4. Connecting plates 1.2 are fixed on both sides of the top of the slide plates 1.1. The two locking devices 3 form a cross groove with the upper column 2.1 for inserting the insert plate 1.

[0043] In one specific embodiment, side plates 2.4 are fixed to the sides of the upper column 2.1 and the lower column 2.2.

[0044] The working principle of this invention is as follows: When the insert plate 1 is inserted into the fixing device 2 from the cross slot, the connecting plate 1.2 first contacts the top of the baffle 3.1 and continues to move downward to press the baffle 3.1 until the bottom of the intermediate plate 1.4 is located on the base 2.3. At this time, the second semicircular groove 1.3 on the connecting plate 1.2 is aligned with the through hole 3.2.2. Under the elastic force of the first elastic guide 3.3.1, the closed guide plate 3.3 moves upward and pushes the steel ball 3.2.3 out of the first semicircular groove 3.3.2 and into the second semicircular groove 3.3.2. Within the groove 1.3, half of the steel ball 3.2.3 is located within the second semi-circular groove 1.3, and the other half is located within the through hole 3.2.2. The connecting plate 1.2 and the follower guide plate 3.2 are connected as a whole through the steel ball 3.2.3. Since the elastic force of the second elastic guide 3.2.1 is greater than that of the third elastic guide 3.1.1, the follower guide plate 3.2 still rests against the lower base 3.5, which plays a vertical constraint role on the connecting plate 1.2, and thus plays a vertical constraint role on the insert plate 1, so that the insert plate 1 will not easily shake.

[0045] To remove the insert plate 1, the greater elastic force of the second elastic guide 3.2.1 compared to the first elastic guide 3.3.1 must be overcome. When removing it, forcefully lift the insert plate 1 upwards. The connecting plate 1.2 and the follower guide 3.2 move upwards together. The baffle 3.1, under the action of the first elastic guide 3.3.1, also moves upwards with the connecting plate 1.2. When the through hole 3.2.2 on the follower guide 3.2 aligns with the first semi-circular groove 3.3.2 on the closed guide 3.3, the baffle 3.1, under the elastic force of the third elastic guide 3.1.1, pushes the steel ball 3.2.3 out of the second semi-circular groove 1.3 and into the first semi-circular groove 1.3. Within groove 3.3.2, half of the steel ball 3.2.3 is located within the first semi-circular groove 3.3.2, and the other half is located within the through hole 3.2.2. The closed guide plate 3.3 and the follower guide plate 3.2 are again integrated by the steel ball 3.2.3. Since the elastic force of the second elastic guide 3.2.1 is greater than that of the first elastic guide 3.3.1, the follower guide plate 3.2 and the closed guide plate 3.3 move downwards until the follower guide plate 3.2 rests against the lower base 3.5, returning to the initial state and releasing the constraint on the connecting plate 1.2. The insert plate 1 can also continue to move upwards until it detaches from the fixing device 2, without affecting the quick replacement of the insert plate 1. Therefore, this invention can provide vertical constraint for the insert plate without affecting the quick replacement of the insert plate 1.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
