Description

Technical Field

[0001] This utility model relates to the field of glass door technology, and in particular to a stop bar for glass doors. Background Technology

[0002] Glass doors are a special type of door, and their characteristics are determined by the properties of the glass itself. For example, when tempered transparent glass is used, the door is transparent, while when frosted glass is used, it is semi-transparent.

[0003] Commercial freezers are used in supermarkets, beverage shops, frozen food stores, hotels, restaurants, and other commercial establishments to store items such as ice cream, beverages, dairy products, frozen foods, and food ingredients. The doors of these freezers utilize glass to allow customers and staff to view the items stored inside. To facilitate access to and storage of items, the freezer doors need to remain open at a certain angle. However, existing freezer doors cannot be secured after opening, making them prone to accidental closure and hindering access to items. Furthermore, the fixed opening angle of existing doors prevents adjustment based on actual usage scenarios, impacting usability. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a stop rod for glass doors.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a stop rod on a glass door, including a first rod, a second rod movably mounted on the first rod, a fixed seat fixedly mounted in the middle of the first rod, an adjustable adjusting plate fitted on the fixed seat, a pressure plate detachably mounted on the top of the fixed seat, a stop block fixedly mounted at the end of the adjusting plate away from the fixed seat, and a limiting block matching the stop block fixedly mounted at the end of the second rod.

[0006] Furthermore, the top of the fixed base is provided with a mounting groove, and racks are fixedly installed on both sides of the mounting groove. The side wall of the adjusting plate is provided with teeth that match the racks. Several sets of threaded holes are provided on the bottom surface of the mounting groove. Several sets of countersunk holes are provided on the top of the pressure plate. The number of countersunk holes is equal to the number of threaded holes. Fixing screws are fitted into the countersunk holes. The adjusting plate is provided with a first oblong hole that matches the fixing screws.

[0007] Furthermore, a number of first connecting platforms are fixedly installed at the bottom of the fixed base. The first connecting platforms are fixedly installed on the first pull rod, and the second pull rod is provided with a second waist-shaped hole that matches the first connecting platform.

[0008] Furthermore, the stop block has a first inclined surface at one end near the limiting block, the bottom end of the first inclined surface is inclined in a direction away from the limiting block, and a limiting groove is formed at the end of the stop block away from the limiting block. The right side wall of the limiting groove is a vertically downward limiting surface, and the left side wall of the limiting groove is a second inclined surface with its bottom end inclined in a direction close to the limiting block.

[0009] Furthermore, the slope of the second inclined surface is greater than the slope of the first inclined surface.

[0010] Furthermore, the limiting block has a cylindrical structure, and a protective ring is fitted around the periphery of the limiting block. The protective ring is made of nylon material.

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-5 As shown, a stop rod for a glass door includes a first rod 1, a second rod 2 movably mounted on the first rod 1, a fixed seat 3 fixedly mounted in the middle of the first rod 1, an adjustable adjusting plate 4 fitted on the fixed seat 3, a pressure plate 5 detachably mounted on the top of the fixed seat 3, a stop block 7 fixedly mounted at the end of the adjusting plate 4 away from the fixed seat 3, and a limiting block 8 matching the stop block 7 fixedly mounted at the end of the second rod 2.

[0023] In this embodiment, the top of the fixed base 3 is provided with a mounting groove 31, and racks 32 are fixedly installed on both sides of the mounting groove 31. The side wall of the adjusting plate 4 is provided with teeth 41 that match the racks 32. The bottom surface of the mounting groove 31 is provided with a plurality of threaded holes 33. The top of the pressure plate 5 is provided with a plurality of countersunk holes 51, the number of countersunk holes 51 being equal to the number of threaded holes 33. Fixing screws 6 are fitted into the countersunk holes 51. The adjusting plate 4 is provided with a first oblong hole 42 that matches the fixing screws 6. The adjusting plate 4 is installed in the mounting groove 31, and the teeth 41 of the adjusting plate 4 are engaged with the racks 32. With the cooperation of the teeth 41 and the racks 32, the position of the adjusting plate 4 is fixed in the mounting groove 31. The fixing screws 6 pass through the first oblong hole 42 and are fitted into the threaded holes 33. The adjusting plate 4 is clamped by the cooperation of the pressure plate 5 and the fixed base 3, preventing the adjusting plate 4 from detaching from the mounting groove 31.

[0024] In this embodiment, a number of first connecting platforms 34 are fixedly installed on the bottom of the fixed base 3. Preferably, there are two sets of first connecting platforms 34. The first connecting platforms 34 are fixedly installed on the first pull rod 1 by riveting. The second pull rod 2 has a second waist-shaped hole 21 that matches the first connecting platform 34. The first connecting platform 34 passes through the second waist-shaped hole 21 and connects to the first pull rod 1. When the second pull rod 2 moves, it avoids the first connecting platform 34 through the second waist-shaped hole 21.

[0025] In this embodiment, the stop block 7 has a first inclined surface 71 at one end near the limiting block 8. The bottom end of the first inclined surface 71 is inclined away from the limiting block 8. A limiting groove 72 is formed at the end of the stop block 7 away from the limiting block 8. The right side wall of the limiting groove 72 is a vertically downward limiting surface 73, and the left side wall of the limiting groove 72 is a second inclined surface 74 with its bottom end inclined towards the limiting block 8. When the second pull rod 2 moves outward, the limiting block 8 moves closer to the stop block 7, and the limiting block 8 abuts against the first inclined surface 71. 1. The thrust of the limiting block 8 is decomposed into an upward thrust, thereby causing the adjusting plate 4 to bend upward. The limiting block 8 passes under the stop block 7 and enters the limiting groove 72. The limiting surface 73 limits the limiting block 8, thereby limiting the second pull rod 2. The slope of the second inclined surface 74 is greater than the slope of the first inclined surface 71. Due to the increased slope of the second inclined surface 74, the thrust of the limiting block 8 on the stop block 7 needs to be increased to make the adjusting plate 4 bend upward, thereby increasing the thrust required when closing the door, and thus preventing the cabinet door from being accidentally closed.

[0026] In this embodiment, the limiting block 8 has a cylindrical structure, and a protective ring 9 is fitted around the periphery of the limiting block 8. The protective ring 9 is made of nylon material. The nylon ring protects the limiting block 8, reduces wear between the limiting block 8 and the stop block 7, and helps to extend the service life of the stop rod.

[0027] In this embodiment, the second pull rod 2 has a mounting hole 22 at one end near the limiting block 8. A second connecting platform 23 is fixedly installed in the mounting hole 22 by riveting. The first pull rod 1 has a third waist-shaped hole 11 that matches the second connecting platform 23. The bottom end of the second connecting platform 23 is provided with an anti-detachment part 231. The second connecting platform 23 is slidably installed in the third waist-shaped hole 11. The second pull rod 2 moves along the third waist-shaped hole 11 through the cooperation between the second connecting platform 23 and the third waist-shaped hole 11, and the anti-detachment part 231 prevents the second pull rod 2 from separating from the first pull rod 1.

[0028] In this embodiment, a first connecting part 12 is fixedly installed on the left end of the first pull rod 1, and the first pull rod 1 is movably connected to the door frame through the first connecting part 12. A second connecting part 24 is rotatably installed on the right end of the second pull rod 2. The second connecting part 24 is a convex piece. The middle part of the second connecting part 24 is hinged to the second pull rod 2. The two ends of the second connecting part 24 are fixedly installed on the upper end of the cabinet door by screws.

[0029] In use, the second pull rod 2 is installed on the cabinet door, and the first pull rod 1 is installed on the door frame. When the cabinet door is opened, the second pull rod 2 moves with the cabinet door. When the cabinet door is opened to its limit position, the limiting block 8 is engaged in the limiting groove 72. Through the cooperation of the limiting block 8 and the stop block 7, the cabinet door is limited while maintaining a certain opening degree, so that users can take out and store items. When closing the door, a certain pushing force is required to disengage the limiting block 8 from the limiting groove 72, thereby preventing the cabinet door from being accidentally closed. Users can adjust the position of the adjusting plate 4 on the fixed base 3 according to the usage scenario, thereby adjusting the front and rear position of the stop block 7, thus adjusting the opening angle of the cabinet door and improving the convenience of the stop pull rod in use.
