Description

Technical Field

[0001] This utility model relates to the technical field of mechanical manufacturing, and in particular to a folding storage and transportation fixture for the sliding door of a railway passenger car compartment. Background Technology

[0002] A door refers to the entrance or exit of a building, or a device installed at the entrance or exit that can be opened and closed. A door is a physical entity that divides a limited space; its function is to connect and close the entrance or exit of two or more spaces. The sliding door of a railway passenger car compartment is a type of door commonly used in railway passenger cars. During the opening and closing process, there is a sliding action, and when closed, the outside of the door is flush with the outer skin of the car body; when open, the door overlaps with the car body. When assembling compartment sliding doors, storage and transportation fixtures are usually required.

[0003] Existing transfer fixtures are welded frame fixtures that occupy a lot of space when not in use. Based on this, we propose a folding storage and transport fixture for the sliding doors of railway passenger car compartments. Utility Model Content

[0004] To address the issue of existing transfer fixtures using welded frame structures that occupy significant space when idle, this invention provides a folding storage and transport fixture for the sliding doors of railway passenger car compartments.

[0005] This utility model provides a folding storage and transportation fixture for the sliding door of a railway passenger car compartment, adopting the following technical solution:

[0006] A folding storage and transportation fixture for a railway passenger car compartment sliding door includes a chassis bracket. Side rails are installed at both the front and rear ends of the top of the chassis bracket. Several hinges are provided at the connection between the chassis bracket and the side rails. A grid is installed at the right end of the top of the chassis bracket, and the grid is located between two sets of side rails. Several pivots are provided at the connection between the grid and the chassis bracket. A locking assembly is provided between the grid and the side rails.

[0007] By adopting the above technical solution, when folding, the locking component releases the fixing effect on the side guards and the partition. Then, the partition is placed flat on the chassis bracket via the pivot, and the side guards are placed flat on the chassis bracket via the hinge. This makes the tooling easy to fold when it is not in use during transport, reducing the space occupied and making it easier to store.

[0008] Optionally, the two sets of side guards are symmetrically distributed about the center of the chassis bracket, and the two sets of side guards have the same structure.

[0009] By adopting the above technical solution, it is possible to block the front and rear ends of an object using two sets of side guards.

[0010] Optionally, the side guard includes a mounting plate, which is connected to the chassis bracket via several hinges. Several square tubes and round tubes are connected to the top of the mounting plate, with the square tubes located on both sides of the round tubes. All of the square tubes and round tubes are configured as hollow structures.

[0011] By adopting the above technical solution, the items on the tooling can be blocked more comprehensively through the cooperation of several square tubes and mounting plates. In addition, the hollow structure reduces the manufacturing cost of square tubes and mounting plates, and also makes square tubes and mounting plates lighter and easier to handle.

[0012] Optionally, a rubber pad is connected to the bottom of the chassis bracket.

[0013] By adopting the above technical solution, the bottom of the chassis bracket becomes more wear-resistant, preventing wear and tear during long-term use.

[0014] Optionally, the locking assembly includes an L-shaped support plate, which is installed at both ends of the inner top wall of the grid. A movable rod is inserted through the inside of the L-shaped support plate. The movable rod passes through the grid on the side opposite to the center of the grid and is fitted with a protrusion. A reserved hole is opened inside the square tube to engage with the protrusion.

[0015] By adopting the above technical solution, the movable rod moves and drives the protrusion to move until the protrusion is inserted into the reserved hole, thereby fixing the position of the side guard and hinge after they are unfolded.

[0016] Optionally, a pull ring is connected to the surface of the movable rod, and a partition is installed at intervals between the L-shaped support plate and the inner sidewall of the grid.

[0017] By adopting the above technical solution, it is convenient for the operator to hold the pull ring and drive the movable rod to move. When the protrusion is inserted into the reserved hole, the partition will engage the inner side of the pull ring, thereby fixing the movable rod.

[0018] In summary, this utility model has at least one of the following beneficial effects:

[0019] By using a combination of chassis bracket, side guards, hinges, dividers, and pivots, when folding, the dividers are placed flat on the chassis bracket via the pivot, and the side guards are placed flat on the chassis bracket via the hinges. This makes the tooling easy to fold when not in use, reducing the space occupied and making it easier to store.

[0020] The tooling is designed with a movable rod, an L-shaped support plate, a pull ring, a partition, a protrusion, and a pre-drilled hole. When the tooling is needed, the pull ring is held to move the movable rod. The movement of the movable rod causes the protrusion to be inserted into the pre-drilled hole, thereby fixing the side guard and hinge for easy use later. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 This utility model provides an embodiment of a folding storage and transportation fixture for a railway passenger car compartment sliding door, including a chassis bracket 1 with a rubber pad fixedly connected to the bottom of the chassis bracket 1. This makes the bottom of the chassis bracket 1 more wear-resistant and prevents wear and tear over long-term use. Side blocks 2 are installed at both the front and rear ends of the top of the chassis bracket 1. The two sets of side blocks 2 are symmetrically distributed about the center of the chassis bracket 1, and the two sets of side blocks 2 have the same structure. This allows the two sets of side blocks 2 to block the front and rear ends of items.

[0031] The side block 2 includes a mounting plate 203, which is rotatably connected to the chassis bracket 1 via several hinges 3. Several square tubes 201 and round tubes 202 are fixedly connected to the top of the mounting plate 203, with the square tubes 201 located on both sides of the round tubes 202. All the square tubes 201 and round tubes 202 are hollow. Through the cooperation of the square tubes 201 and the mounting plate 203, items on the tooling can be more comprehensively blocked. Furthermore, the hollow structure reduces the manufacturing cost of the square tubes 201 and the mounting plate 203, making them lighter and easier to handle.

[0032] Several hinges 3 are provided at the connection between the chassis bracket 1 and the side guard 2. A guard 4 is installed at the right end of the top of the chassis bracket 1, and the guard 4 is located between the two sets of side guards 2. Several pivots 5 are provided at the connection between the guard 4 and the chassis bracket 1. A locking assembly 6 is provided between the guard 4 and the side guard 2.

[0033] The locking assembly 6 includes an L-shaped support plate 602, which is fixedly installed at both ends of the inner top wall of the partition 4. A movable rod 601 is slidably inserted inside the L-shaped support plate 602. The movable rod 601 passes through the partition 4 on the side opposite to the center of the partition 4 and is fixedly installed with a protrusion 605. A reserved hole 606 is opened inside the square tube 201 to engage with the protrusion 605. The movement of the movable rod 601 drives the protrusion 605 to move until the protrusion 605 is inserted into the reserved hole 606, thereby fixing the position of the side block 2 and the hinge 3 after they are unfolded.

[0034] A pull ring 603 is fixedly connected to the surface of the movable rod 601. A partition 604 is installed between the L-shaped support plate 602 and the inner side wall of the grid 4. This allows the operator to hold the pull ring 603 and move the movable rod 601. When the protrusion 605 is inserted into the reserved hole 606, the partition 604 engages with the inner side of the pull ring 603, thereby fixing the movable rod 601.

[0035] Working principle: During use, the side guard 2 rotates along the chassis bracket 1 via the hinge 3 until the side guard 2 is unfolded. At the same time, the guard 4 rotates along the chassis bracket 1 via the rotating shaft 5 until the guard 4 is unfolded. Then, the operator holds the pull ring 603 and pulls the pull ring 603 to move the movable rod 601. The movement of the movable rod 601 moves the protrusion 605 until the protrusion 605 is inserted into the reserved hole 606, thereby fixing the side guard 2 and the hinge 3 and preventing the side guard 2 and the hinge 3 from rotating during use.

[0036] When it is necessary to fold the side guard 2 and hinge 3, pull the pull ring 603 again to separate the protrusion 605 from the reserved hole 606, thereby releasing the fixing effect on the side guard 2 and hinge 3. Then, place the guard 4 flat on the chassis bracket 1 through the pivot 5, and then place the side guard 2 flat on the chassis bracket 1 through the hinge 3. This makes the tool easy to fold when it is not in use during transportation, reducing the space occupied and making it easier to store.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
