Description

Technical Field

[0001] The utility model relates to the technical field related to a locking auxiliary tool for a train compartment door, in particular to a locking auxiliary tool for a train compartment door which is easy to position. Background Art

[0002] When the train is moving, the compartment door must be kept in a normally closed state. In order to lock the compartment door, it is necessary to manually close the door frequently. However, the door is heavy and difficult to close, and there is no special auxiliary equipment. Therefore, the labor intensity of the operator is extremely high, and closing the door is time-consuming and laborious. In addition, when the operator closes the door, it is easy to operate improperly, which may cause safety hazards such as being hit or squeezed.

[0003] In order to overcome the above defects, prior art 1 (Chinese patent with application number 202120909558.7 and application date 2021-04-29) is a special tool for closing the door of a train carriage, including a pressure rod and a door closing device; the door closing device includes a top pressure block, a support arm and a caliper, the top pressure block is arranged at one end of the pressure rod, and the end of the pressure rod away from the top pressure block is provided with an anti-slip sleeve, and the anti-slip sleeve is made of rubber; the support arm is provided with a self-lubricating bearing at the end away from the pressure rod, and a connecting shaft is installed between the support arms through the self-lubricating bearing; the caliper is hinged between the support arms through the connecting shaft, the operator holds the pressure rod, hooks the caliper with the carriage, and then presses the top pressure block against the door, and then lifts up with the help of the pressure rod to close the door tightly;

[0004] Although the existing technology can close the car door, during the operation, a caliper is hinged between the support arms through a connecting shaft, and the door closing operation is performed by using the cooperation of the caliper and the top pressure block. The connecting shaft easily causes the caliper to rotate, resulting in poor stability in the connection between the caliper and the bottom of the car, which causes slipping during operation, making the overall door closing operation more complicated, time-consuming and labor-intensive, reducing the door closing efficiency, and easily injuring the operator by mistake.

[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original train compartment door locking auxiliary tool that is easy to locate. Therefore, we propose a train compartment door locking auxiliary tool that is easy to locate and can solve the above problems well. Utility Model Content

[0006] The purpose of the present utility model is to provide an auxiliary tool for locking the train carriage door that is convenient for positioning, so as to solve the problems mentioned in the above background technology. At present, on the market, a caliper is hinged between support arms through a connecting shaft, and the caliper and a pressing block are used in cooperation for closing the door. Among them, the connecting shaft easily causes the caliper to rotate, resulting in poor connection stability between the caliper and the bottom of the carriage, thereby causing slipping during the operation process, making the overall door closing operation more complex, time-consuming and laborious, reducing the door closing efficiency, and being prone to accidentally injuring the operator.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: An auxiliary tool for locking the train carriage door that is convenient for positioning, including a set pressing rod, and a pressing block is welded on the pressing rod;

[0008] A first through groove is opened on the pressing block, a first rotating block is connected to the side end of the pressing block, a second through groove is opened on the first rotating block, and the inside of the second through groove is connected to the inside of the first through groove through a rotating shaft. A caliper is welded to the side end of the first rotating block. The rotating shaft is passed through the second through groove of the first rotating block and clamped inside the first through groove of the pressing block, so that the caliper welded on the first rotating block is convenient to use. Since the first rotating block is welded to the caliper, the caliper can be moved to the bottom of the carriage, which is convenient for later borrowing force operation. The caliper can be quickly positioned and fixed, reducing the problem of poor overall stability caused by rotational connection. The first rotating block is rotated through the rotating shaft, which is convenient for the first rotating block to move to the position of the door bolt. At this time, the operator holds the pressing rod, stabilizes the overall structure through the cooperation of the first rotating block and the caliper, and uses the lever principle to borrow force to lift the pressing rod to close the door tightly, reducing the problem of accidental injury caused by slipping.

[0009] Preferably, the caliper is arc-shaped, a first anti-slip layer is installed on the inner side of the caliper, and a reinforcement layer is arranged on the inner side of the caliper. The caliper is arc-shaped, and the first anti-slip layer on the inner arc makes the contact between the caliper and the bottom of the carriage more stable, increasing the friction force on the contact surface between the caliper and the bottom of the carriage, improving the convenience of the overall operation. The arranged reinforcement layer increases the durability of the caliper, reducing the problem of reduced service life caused by wear during the use of the caliper.

[0010] Preferably, a second anti-slip layer is arranged on the surface of the pressing block, a buffer layer is installed inside the second anti-slip layer, and a support layer is arranged inside the buffer layer. The surface of the pressing block increases the friction force on the contact surface with the position of the door bolt through the second anti-slip layer, avoiding the problem of reduced door closing efficiency caused by displacement during the operation process. The buffer layer is convenient for dispersing the pressure applied on the pressing block, reducing the impact force on the carriage door. The arranged support layer can provide structural support and stability, reducing the deformation problem caused by long-term use.

[0011] Preferably, a hand-held sleeve is sleeved outside the pressure rod, and a storage groove is formed inside the hand-held sleeve.

[0012] Preferably, a clamping groove is formed at the end of the hand-held sleeve, and the clamping groove communicates with the storage groove.

[0013] Preferably, a rubber block is installed inside the storage groove. The rubber block is adapted to the groove. The groove is formed on the surface of the pressure rod. The pressure rod is penetrated through the clamping groove of the hand-held sleeve, and the rubber block inside the storage groove is clamped inside the groove formed on the surface of the pressure rod, so that the hand-held sleeve is stably connected to the pressure rod. The hand-held sleeve not only makes the operation feel more comfortable, but also can protect the surface of the pressure rod from wear and corrosion, thereby prolonging the service life of the tool.

[0014] Preferably, a through pipe is formed inside the pressure rod, a threaded pipe is installed at the bottom of the through pipe, and a sealing block is threadedly connected inside the threaded pipe.

[0015] Preferably, a second rotating block is connected to the sealing block. The second rotating block is installed inside the card slot. The card slot is formed at the bottom end of the pressure rod. The second rotating block inside the card slot is rotated, so that the sealing block is rotated out of the threaded pipe, which is convenient for the user to pour counterweight particles into the through pipe according to the required weight, so that the overall weight of the tool can be conveniently adjusted, and the formed through pipe makes the whole more light, so as to facilitate the overall carrying of the tool.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: for the auxiliary tool for locking the train carriage door which is convenient for positioning, the rotating shaft is clamped inside the first through groove of the top pressing block through the second through groove of the first rotating block, the caliper is moved to the bottom of the carriage, and the first rotating block is rotated through the rotating shaft, which is convenient for the first rotating block to move to the position of the door bolt. The operator holds the pressure rod, and the overall structure is stabilized through the cooperation of the first rotating block and the caliper. The pressure rod is lifted by leveraging the lever principle, and the carriage door is closed tightly, reducing the problem of accidental injury caused by slipping. The specific content is as follows:

[0017] (1) Since the first rotating block and the caliper are welded, moving the caliper to the bottom of the carriage is convenient for subsequent leveraging operations, reducing the problem of poor overall stability caused by rotational connection, improving the efficiency of closing the door, and reducing the problem of accidental injury caused by slipping;

[0018] (2) The first anti-slip layer on the inner side of the arc makes the contact between the caliper and the bottom of the carriage more stable, reducing the problem of potential safety hazards caused by the sliding of the caliper. The provided reinforcement layer increases the durability of the caliper, reducing the problem of reduced service life caused by wear of the caliper during use;

[0019] (3) The second anti-slip layer on the surface of the top pressure block increases the friction between the contact surface with the door latch position, avoiding the problem of displacement during operation that leads to reduced door closing efficiency. The support layer can provide structural support and stability, thereby increasing the overall service life;

[0020] (4) The rubber block inside the storage slot is clamped into the groove on the surface of the pressure rod, so that the hand-held cover is stably connected to the pressure rod. The hand-held cover makes the hand feel more comfortable during operation, and reduces the problem of the hand-held cover being easily removed during later use due to being put on the outside of the pressure rod;

[0021] (5) By rotating the second rotating block, the sealing block is rotated out from the inside of the threaded tube, which makes it convenient for the user to pour out the weight particles inside the through tube, making the whole tool lighter, thereby facilitating the carrying of the tool as a whole and improving the overall practicality.

DETAILED DESCRIPTION

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1:

[0031] In this embodiment, in order to improve the overall stability, the top pressing block 2 is used in conjunction with the caliper 7. The purpose is to reduce the problem of poor overall stability caused by rotational connection. For example Figures 1-3 As shown in the technical solution, it includes a set pressing rod 1. A top pressing block 2 is welded on the pressing rod 1. A first through groove 3 is opened on the top pressing block 2. A first rotating block 4 is connected to the side end of the top pressing block 2. A second through groove 5 is opened on it. The inside of the second through groove 5 is connected to the inside of the first through groove 3 through a rotating shaft 6. A caliper 7 is welded to the side end of the first rotating block 4. The pressing rod 1 is convenient to be welded with the top pressing block 2. Therefore, the length of the pressing rod 1 can be adjusted according to the required length, greatly improving the overall practicability and facilitating the operation and use by the user. The problem of inconvenient use caused by the fixed length of the pressing rod 1 is reduced. The rotating shaft 6 is passed through the second through groove 5 of the first rotating block 4 and clamped inside the first through groove 3 of the top pressing block 2, making the caliper 7 welded on the first rotating block 4 convenient to use. Since the first rotating block 4 is welded to the caliper 7, the caliper 7 is moved to the bottom of the carriage, facilitating the subsequent borrowing of force for operation. The caliper 7 is convenient for quick positioning and fixing, reducing the problem of poor overall stability caused by rotational connection, resulting in simple overall operation, improving the efficiency of closing the door, and rotating the first rotating block 4 through the rotating shaft 6, facilitating the first rotating block 4 to move to the position of the door bolt. At this time, the operator holds the pressing rod 1, stabilizes the overall structure through the cooperation of the first rotating block 4 and the caliper 7, and uses the lever principle to borrow force to lift the pressing rod 1 to close the door tightly, reducing the problem of accidental injury caused by slipping. Embodiment 2:

[0032] In this embodiment, in order to improve the overall service life, a reinforcing layer 9 is used. The purpose is to reduce the problem of reduced service life caused by wear of the caliper 7 during use. Specifically, as Figures 1-4As shown, the caliper 7 is arranged in an arc shape. A first anti-slip layer 8 is installed on the inner side of the caliper 7, and a reinforcement layer 9 is provided on the inner side of the caliper 7. A second anti-slip layer 10 is provided on the surface of the pressing block 2. A buffer layer 11 is installed inside the second anti-slip layer 10, and a support layer 12 is provided inside the buffer layer 11. The caliper 7 is arranged in an arc shape. The first anti-slip layer 8 on the inner side of the arc makes the contact between the caliper 7 and the bottom of the carriage more stable, increases the friction force between the contact surface of the caliper 7 and the bottom of the carriage, reduces the problem of potential safety hazards caused by the sliding of the caliper 7, improves the convenience of the overall operation. The provided reinforcement layer 9 increases the durability of the caliper 7, provides additional structural support, and reduces the problem of reduced service life caused by wear during the use of the caliper 7. The surface of the pressing block 2 increases the friction force with the contact surface of the door bolt position through the second anti-slip layer 10, prevents sliding when applying pressure, ensures that the pressing block 2 is stably fixed on the door, and avoids the problem of reduced closing efficiency caused by displacement during the operation. The buffer layer 11 facilitates the dispersion of the pressure applied to the pressing block 2, reduces the impact force on the carriage door, makes the overall pressure distribution uniform, and facilitates the closing operation. The provided support layer 12 can provide structural support and stability, ensure that the pressing block 2 can maintain its shape when applying pressure, reduce the deformation problem caused by long-term use, and improve the overall service life. Embodiment Three:

[0033] In this embodiment, in order to improve the overall portability, it is used through the provided through pipe 18. The opened through pipe 18 makes the whole more lightweight, thus facilitating the overall carrying of the tool, specifically as Figures 5-7As shown, a hand-held sleeve 13 is sleeved outside the pressure rod 1. An object placement groove 14 is formed inside the hand-held sleeve 13. A clamping groove 15 is formed at the end of the hand-held sleeve 13. The clamping groove 15 communicates with the object placement groove 14. A rubber block 17 is installed inside the object placement groove 14. The rubber block 17 is adapted to the groove 16. The groove 16 is formed on the surface of the pressure rod 1. A through pipe 18 is formed inside the pressure rod 1. A threaded pipe 19 is installed at the bottom of the through pipe 18. A sealing block 22 is threadedly connected inside the threaded pipe 19. The sealing block 22 is connected with a second rotating block 21. The second rotating block 21 is installed inside the clamping groove 20. The clamping groove 20 is formed at the bottom end of the pressure rod 1. The pressure rod 1 is penetrated through the clamping groove 15 of the hand-held sleeve 13, and the rubber block 17 inside the object placement groove 14 is clamped inside the groove 16 formed on the surface of the pressure rod 1, so that the hand-held sleeve 13 is stably connected with the pressure rod 1. The hand-held sleeve 13 makes the operation feel more comfortable, reducing the problem that it is easy to fall off during later use when the hand-held sleeve 13 is sleeved outside the pressure rod 1. Using the pressure rod 1 through the hand-held sleeve 13 not only improves the overall operation stability, but also the hand-held sleeve 13 can protect the surface of the pressure rod 1 from wear and corrosion, thereby extending the service life of the tool. Rotating the second rotating block 21 inside the clamping groove 20 makes the sealing block 22 rotate out of the threaded pipe 19, facilitating the user to pour counterweight particles into the through pipe 18 according to the required weight, so that the overall weight of the tool can be conveniently adjusted, resulting in greatly improved overall practicality. The formed through pipe 18 makes the whole more lightweight, thus facilitating the overall carrying of the tool.
