Description

Technical Field

[0001] The present invention relates to the technical field of display cabinet sealing, and in particular to a movable sealing device for a display cabinet. Background Art

[0002] Display cabinets are often used to display valuable items that cannot be exposed to air for extended periods or handled casually, such as expensive jewelry or precious artifacts. Due to their unique nature, these valuable items must be completely isolated from the outside world during display. To address this issue, most display cabinets feature sealing strips around the doors.

[0003] For rotating cabinet doors, the design of the sealing strip does not affect the opening and closing of the cabinet door or the sealing performance of the sealing strip. However, for sliding cabinet doors, the sealing strip needs to be fixed to the cabinet body or the sliding cabinet door. Not only is the sliding door's sliding smoothness affected by the sealing strip, but the sliding cabinet door itself and the sealing strip, or the sealing strip and the cabinet body, will repeatedly rub against each other during opening and closing. Over time, the sealing strip will be worn to varying degrees, and the sealing effect will be reduced or even lost. As a result, valuable items cannot be completely isolated from the outside world during display. Outside air can enter the display cabinet along the damaged sealing strip, corroding the valuables. During long-term display, the value of the valuables will be affected. For precious cultural relics, air erosion can even cause irreparable damage. Summary of the Invention

[0004] The purpose of the present invention is to provide a movable sealing device for display cabinets, which can increase the distance between the sliding cabinet door and the sealing strip during the sliding process of the sliding cabinet door to prevent relative friction between the sliding cabinet door and the sealing strip.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A movable sealing device for a display cabinet, the display cabinet includes a base and a sliding cabinet door, the movable sealing device for the display cabinet includes a side sealing assembly, which includes a guide rail slidably connected to the base and a side movable plate movably connected to the guide rail, a guide block protruding from the guide rail, a curved guide bend groove provided on the side movable plate, the guide block is stuck in the guide bend groove and is slidably connected to the side movable plate; a side sealing strip is fixed to the side movable plate, the side sealing strip faces the sliding cabinet door and is located at the edge of the base; the guide rail drives the guide block to move in the same direction as the sliding cabinet door, the guide block slides relative to the guide bend groove, and the side movable plate moves relative to the guide block in a direction close to or away from the sliding cabinet door.

[0007] Preferably, a side elastic member is further connected between the guide rail and the base, and the elastic force direction of the side elastic member is parallel to the moving direction of the guide rail.

[0008] Preferably, the side sealing assembly further comprises a side sealing plate fixed on the side movable plate, the side sealing plate moves synchronously with the side movable plate, and the side sealing strip is fixed on the edge of the side sealing plate.

[0009] Preferably, the side sealing assembly also includes a limit block fixed on the base, and a limit slot adapted for the limit block is opened on the guide rail. The limit block is inserted into the limit slot and slidably connected to the guide rail, and the length direction of the limit slot is the same as the moving direction of the guide rail.

[0010] Preferably, the sliding cabinet door is L-shaped, the side sealing assembly faces the long side of the sliding cabinet door, and when the sliding cabinet door moves, its short side contacts the movable guide rail; when the side elastic member is originally long, the end of the guide rail close to the sliding cabinet door protrudes from the base.

[0011] Preferably, the movable sealing device for the display cabinet also includes a positive sealing component facing the short side of the sliding cabinet door, which includes a positive movable plate slidably connected to the base, and its sliding direction is the same as the moving direction of the sliding cabinet door. A positive sealing strip facing the short side of the sliding cabinet door is fixed on the positive movable plate, and the positive sealing strip is located at the edge of the base.

[0012] Preferably, the positive sealing assembly also includes a positive positioning block fixed on the base, a positive elastic member arranged on the positive positioning block, and a positive sliding block connected to the positive positioning block through the positive elastic member; when the positive elastic member is at its original length, the side of the positive movable plate close to the short side of the sliding cabinet door protrudes from the base; the positive movable plate moves in the direction of approaching or moving away from the short side of the sliding cabinet door.

[0013] Preferably, the positive sealing assembly further comprises a positive sealing plate fixed on the positive movable plate, and the positive sealing strip is fixed on an edge of the positive sealing plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: when the sliding cabinet door slides open, the guide rail and the sliding cabinet door move in the same direction at the same time, driving the guide block to move synchronously, the guide block slides relative to the guide bend groove, and the side movable plate drives the side sealing strip to move in the direction away from the sliding cabinet door. At this time, a gap is formed between the sliding cabinet door and the side sealing strip, and the subsequent sliding cabinet door will not generate friction with the side sealing strip during the continued sliding of the sliding cabinet door; when the sliding cabinet door slides closed, the side sealing strip always forms a gap with the sliding cabinet door, and the two will not generate friction. When the sliding cabinet door slides to a state about to be closed, the guide rail and the sliding cabinet door move in the same direction at the same time, driving the guide block to move synchronously, the guide block slides relative to the guide bend groove, and the side movable plate drives the side sealing strip to move in the direction close to the sliding cabinet door until the side sealing strip is tightly sealed with the sliding cabinet door. During the entire process of the sliding cabinet door sliding open or closed, the side sealing strip and the sliding cabinet door will not rub repeatedly, and the side sealing strip will not be worn out, resulting in a decrease in the sealing effect or even a direct loss of the sealing effect. Ensure that valuables are always completely isolated from the outside world during the display process, and the outside air will not enter the display cabinet and corrode the valuables, thus ensuring the value of the valuables.

DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please see Figures 1 to 3 A movable sealing device for a display cabinet, the display cabinet includes a base 9 and an L-shaped sliding cabinet door, the sliding cabinet door moves in the longitudinal direction of the long side. The movable sealing device for the display cabinet includes a side sealing assembly 1, which includes a straight guide rail 101 slidably connected to the base 9 and arranged horizontally, and a side movable plate 102 movably connected to the guide rail 101 and arranged horizontally. A guide block 1011 protrudes vertically upward on the guide rail 101, and a curved guide groove 1021 is formed on the side movable plate 102, which is curved and adapted to the guide block 1011. The guide block 1011 is inserted into the guide groove 1021 and is slidably connected to the side movable plate 102, that is, the guide block 1011 can slide relative to the guide groove 1021; a side sealing strip is fixed to the side movable plate 102 along the longitudinal direction, and the side sealing strip is opposite to the long side of the sliding cabinet door and is located at the edge of the base 9. The moving direction of the guide rail 101 is the same as the moving direction of the sliding cabinet door. The moving direction of the guide rail 101 is the moving direction of the guide block 1011. The guide block 1011 moves relative to the guide curved groove 1021, and the side movable plate 102 moves toward or away from the long side direction of the sliding cabinet door and perpendicular to the guide rail 101. The sum of the moving trajectories of the simultaneous movement of the guide block 1011 and the side movable plate is the shape of the guide curved groove 1021.

[0028] Please see Figure 4 、 Figure 5 Furthermore, the guide rail 101 is fixedly connected to a connector 103, which is slidably connected to a fixed rod 104 and fixedly connected to a side elastic member 105. The side elastic member 105 is sleeved on the fixed rod 104 without the two contacting each other. The fixed rod 104 is used to limit the movement direction of the side elastic member 105. The side elastic member 105 is also aligned with a fixed block 106 fixed to the base 9. The side elastic member 105 is driven by the guide rail 101 to move toward the fixed block 106 until it contacts the fixed block 106 and is compressed. The side elastic member 105 is a spring, and its elastic force direction is parallel to the movement direction of the guide rail 101. The original length of the side elastic member 105 is less than the length of the guide bend 1021. When the guide rail 101 moves forward, it compresses the side elastic member 105, causing the side movable plate 102 to move toward the long side of the sliding door until it presses against the long side of the sliding guide rail 101, achieving a seal. When the guide rail 101 moves backward, the side elastic member 105 returns to its original length, causing the side movable plate 102 to spring away from the long side of the sliding door, creating a gap between the sealing strip and the long side of the sliding door. When the side elastic member 105 is at its original length, the end of the guide rail 101 closest to the sliding door protrudes beyond the base 9, facilitating the application of force to push the guide rail 101.

[0029] Please see Figure 3Furthermore, the side sealing assembly 1 further includes a side sealing plate 107 fixed to the side movable plate 102. The side sealing plate 107 moves synchronously with the side movable plate 102, and the side sealing strip is fixed to the edge of the side sealing plate 107. This facilitates direct replacement of the side sealing plate 107 when the side sealing strip is damaged.

[0030] Please see Figure 5 Furthermore, the side seal assembly 1 further includes a stopper 108 fixed to the base 9. The guide rail 101 is provided with a stopper slot 1012 adapted to fit within the stopper 108. The stopper 108 engages with the stopper slot 1012 and is slidably connected to the guide rail 101. The length of the stopper slot 1012 is the same as the direction of movement of the guide rail 101. The stopper 108 and the stopper slot 1012 cooperate to limit the direction of movement of the guide rail 101 and serve as one embodiment of the slidable connection between the guide rail 101 and the base 9.

[0031] Please see Figure 6 Furthermore, the side seal assembly 1 further includes a side positioning block 109 fixed to the base 9, a side positioning rod 110 provided on the side positioning block 109, and a side sliding block 111 slidably connected to the side positioning rod 110. The length direction of the side positioning rod 110 is perpendicular to the moving direction of the guide rail 101. The side sliding block 111 moves along the length direction of the side positioning rod 110. The side sliding block 111 is fixedly connected to the side movable plate 102. The side positioning block 109, the side positioning rod 110, and the side sliding block 111 cooperate to limit the moving direction of the side movable plate 102. Please refer to Figure 1 、 Figure 2 Furthermore, the side sealing assembly 1 is one or more arranged horizontally along the length direction, the guide rails 101 of all the side sealing assemblies 1 are integrated, and all the side sealing assemblies 1 form a group of side sealing assemblies 1, and the length of a group of side sealing assemblies 1 is adapted to the length of the base 9.

[0032] Please see Figure 1 、 Figure 2 、 Figure 7 Furthermore, the movable sealing device for the display cabinet also includes a positive sealing component 2 facing the short side of the sliding cabinet door, which includes a positive movable plate 201 slidably connected to the base 9 and horizontally arranged, and its moving direction is the same as the moving direction of the sliding cabinet door. A positive sealing strip facing the short side of the sliding cabinet door is fixed on the positive movable plate 201 along the length direction, and the positive sealing strip is located at the edge of the base 9.

[0033] Please see Figures 7 and 8Furthermore, the positive sealing assembly 2 also includes a positive positioning block 202 fixed to the base 9, a positive elastic member 203 disposed on the positive positioning block 202, a positive sliding block 204 connected to the positive positioning block 202 via the positive elastic member 203, and a positive positioning rod 205 slidably connected to the positive sliding block 204. The positive elastic member 203 is a spring. When in its original length, the side of the positive movable plate 201 near the short side of the sliding door protrudes from the base 9, facilitating the application of pressure to the positive movable plate 201 to propel it forward. The positive sliding block 204 slides relative to the positive positioning rod 205, causing the positive movable plate 201 to move toward or away from the short side of the sliding door.

[0034] Please see Figure 7 Furthermore, the positive sealing assembly 2 further includes a positive sealing plate 206 fixed on the positive movable plate 201, and a positive sealing strip is fixed to the edge of the positive sealing plate 206. It is convenient to directly replace the positive sealing plate 206 when the positive sealing strip is damaged.

[0035] Please see Figure 1 Furthermore, the base 9 is a rectangular parallelepiped, and the long sides and short sides of the sliding doors and the base 9 are opposite each other. The sliding doors are two identical triangular prisms that are offset and open opposite each other. The long side of each sliding door faces a set of side seal assemblies 1, and the short side faces a positive seal assembly 2. That is, a set of side seal assemblies 1 is provided on each of the two opposite long sides of the base 9, and a positive seal assembly 2 is provided on each of the two opposite short sides.

[0036] The working principle of this device is:

[0037] 1. When the sliding door is closed:

[0038] Apply force to push the sliding cabinet door, and the short side of the sliding cabinet door moves toward the base 9 until it contacts one end of the guide rail 101 and one side of the positive movable plate 201. The sliding cabinet door continues to move in the same direction, driving the guide rail 101 and the positive sealing plate 206 to move forward.

[0039] Working principle of the side sealing assembly 1: the limit block 108 is fixed relative to the base 9 and moves relative to the limit long groove 1012; the guide rail 101 compresses the side elastic member 105 after moving a certain distance, and drives the guide block 1011 to move in the same direction; the guide block 1011 slides relative to the guide curved groove 1021, driving the side movable plate 102 to move toward the long side of the sliding cabinet door, and the side movable plate 102 drives the side sliding block 111 to move along the side positioning rod 110. At the same time, the side movable plate 102 drives the side sealing plate 107 to move, and the side sealing plate 107 drives the side sealing strip to move toward the long side of the sliding cabinet door until it is tightly pressed against the long side of the sliding cabinet door to achieve sealing.

[0040] The working principle of the positive sealing assembly 2: the short side of the sliding cabinet door contacts the positive sealing strip on the positive sealing plate 206, the positive sealing plate 206 drives the positive movable plate 201 to move, the positive movable plate 201 drives the positive sliding block 204 to slide along the positive positioning rod 205, and the positive sliding block 204 compresses the positive elastic part 203 until the positive sealing strip presses against the short side of the sliding cabinet door to achieve sealing.

[0041] 2. When the sliding door slides open:

[0042] Apply force to open the sliding door, and the short side of the sliding door moves away from the base 9.

[0043] Working principle of the side sealing assembly 1: the limit block 108 is fixed relative to the base 9, and moves rapidly relative to the limit long groove 1012; the side elastic member 105 loses pressure and quickly recovers its original length; the guide rail 101 moves rapidly in the direction of the guide block 1011, and drives the guide block 1011 to move rapidly in the same direction; the guide block 1011 slides rapidly relative to the guide bend groove 1021, driving the side movable plate 102 to move rapidly away from the long side of the sliding cabinet door, and the side movable plate drives the side sliding block 111 to move rapidly along the side positioning rod 110. At the same time, the side movable plate drives the side sealing plate 107 to move rapidly, and the side sealing plate 107 drives the side sealing strip to bounce away from the long side of the sliding cabinet door.

[0044] Working principle of the positive sealing assembly 2: the positive elastic member 203 gradually returns to its original length, and under the elastic force of the positive elastic member 203, the positive sealing plate 206 moves synchronously with the short side of the sliding cabinet door, driving the positive movable plate 201 to move synchronously, and the positive movable plate 201 drives the positive sliding block 204 to slide along the positive positioning rod 205 until the positive elastic member 203 completely returns to its original length, and the positive sealing assembly 2 is fixed; the short side of the sliding cabinet door continues to move away from the base 9, and the positive sealing strip separates from the short side of the sliding cabinet door.
