Technical Field
[0001] The utility model relates to the field of elevators, in particular to an elevator toe guard. Background Art
[0002] An elevator toe guard, also known as an elevator sill guard, is a device used to protect the elevator door sill. Commonly used toe guards are fixed metal plates installed at the bottom of the elevator door. Their purpose is to prevent passengers' feet or other objects from being caught in the elevator door, while also protecting the door sill from wear and damage.
[0003] However, although the conventional toe guard structure using fixed metal plates can meet basic usage requirements, it is often simple in structure and is prone to friction with the pit wall during the up and down movement of the elevator. On the one hand, the deformation of the toe guard is likely to cause large operating noise and is inconvenient to repair; on the other hand, the conventional toe guard structure is usually relatively simple in function, and abnormal conditions of the toe guard during the operation of the elevator cannot be discovered in time, further increasing the operating risk of the elevator and the potential dangers of the passengers on it. Utility Model Content
[0004] The purpose of the utility model is to provide an elevator toe board, which can give an alarm in time for abnormal situations occurring thereon, and the overall structure has a certain strength and can ensure the functional stability of the toe board.
[0005] The technical solution adopted by the present invention to solve the above problems is:
[0006] An elevator toe guard comprises a mounting frame provided at a corresponding position on the bottom of the elevator and a toe guard body mounted on a corresponding position on the bottom of the ground through the mounting frame. The toe guard body comprises a first plate body mounted on the mounting frame through a detachable structure and a second plate body connected thereto through multiple sets of compression springs and of an adaptive size. A rib is provided along the edge of the second plate body around the edge of the first plate body. A pin is provided on the second plate body and the corresponding pin is passed through a through hole opened at a corresponding position on the first plate body and is connected to a locking ring. A sensor is installed at the position of the through hole opened on the first plate body.
[0007] Furthermore: the mounting frame includes multiple groups of channel steels arranged horizontally and vertically and arranged in different sizes and connected by bolts, and the corresponding connecting surfaces of the channel steels connected to the second plate body and the multiple groups of channel steels arranged horizontally and vertically are all provided with sliding grooves.
[0008] Furthermore: the second plate body is surrounded by a retaining edge, and an opening structure is provided at a position corresponding to the contact with the bottom of the elevator along the installation direction of the toe guard body.
[0009] Furthermore: a matching third plate structure can be detachably mounted on the corresponding retaining edge of the second plate.
[0010] Furthermore: a second compression spring is sleeved on the corresponding pin rod of the second plate body.
[0011] Furthermore: the compression spring and the second compression spring are both installed at corresponding positions on the plate surface of the first plate body through a detachable structure.
[0012] Compared with the prior art, the present invention has the following advantages and effects:
[0013] The utility model discloses an elevator toe guard. The structure of the elevator toe guard body is arranged in accordance with the connection mode of the first plate body and the second plate body. The second plate body is provided with a plurality of compression springs between the first plate body and the second plate body, so that the elevator can slide in the corresponding direction in response to abnormal conditions such as bulges on the pit wall during operation, and play a certain buffering role. It can further reduce the degree of wear of the toe guard body and the stability of its overall structure. The setting of the retaining edge on the second plate body can effectively reduce the entry of internal dust. At the same time, when the elevator is running and passengers go up and down, in the event of foreign objects falling, the foreign objects slide downward along the elevator door gap and are correspondingly stuck on the bottom toe guard body, the second plate body can Under the action of multiple groups of compression springs, a corresponding movement distance is generated in the direction approaching the first plate body, and the corresponding pin rod and locking ring arranged thereon are driven to move in the corresponding direction on one side of the first plate body. At the same time, when the pin rod and locking ring move to the detection range of the sensor at the corresponding through-hole position on the second plate body, the corresponding sensor is triggered and sends an alarm signal to the elevator main control circuit through the signal line, thereby stopping the elevator from running. Timely alarm can be issued for abnormal conditions of the toe guard plate body, reducing the operation risk of the elevator and ensuring the safety of passengers during operation. In addition, the connection structure between the toe guard plate body and the mounting frame is also relatively simple, which is convenient for daily inspection and subsequent maintenance operations, and improves the convenience and flexibility of the installation process.

DETAILED DESCRIPTION
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0021] See also Figure 1-4 , this embodiment relates to an elevator toe guard, including a mounting frame 101 provided at a corresponding position on the bottom of an elevator 100 and a toe guard body 1 installed at a corresponding position on the bottom of a ground body through the mounting frame 101, the toe guard body 1 includes a first plate body 11 mounted on the mounting frame 101 through a detachable structure and a second plate body 12 connected thereto by multiple groups of compression springs 13 and of an adaptive size, the edge of the second plate body 12 is provided with a rib 121 around the edge of the first plate body 11, the second plate body 12 is provided with a pin rod 122 and the corresponding pin rod 122 passes through a through hole 111 opened at a corresponding position on the first plate body 11 and is connected to a locking ring 123, and a sensor 112 is installed at the position of the through hole 111 opened on the first plate body 11.
[0022] Specifically in this embodiment, Figure 1 The bottom of the elevator 100 is installed by the installation frame 101, and the elevator 100 footboard body 1 can also be seen. Figure 2 The connection between the mounting bracket 101 and the footboard body 1 is shown in FIG. , and the specific installation process can be referred to Figure 3 As shown, the mounting bracket 101 is mounted on the corresponding position of the bottom of the elevator 100 by means of a bolt 110, and the toe guard body 1 can be passed through the corresponding mounting bracket 101 by means of a threaded rod 113 provided on the corresponding position of the first plate body 11 and locked by means of a corresponding nut 114, so that the toe guard body 1 is fixed on the mounting bracket 101, completing the installation process of the toe guard body 1. In addition, in the early stage of the installation of the toe guard body 1, the corresponding structures of the first plate body 11 and the second plate body 12 can be pre-assembled, as shown in FIG. Figure 4As shown, the corresponding plate surfaces of the first plate body 11 are correspondingly equipped with multiple groups of compression springs 13, and the second plate body 12 is placed on one side of the multiple groups of springs on the first plate body 11 and is correspondingly penetrated into the through holes 111 opened at the corresponding positions of the first plate body 11 through the pin rods 122 provided thereon, so that the second plate body 12 is placed at the corresponding position on one side of the first plate body 11, and the second plate body 12 is locked in the corresponding position relative to the first plate body 11 through the locking ring 123. The pin rod 122 and the locking ring 123 can be adaptively connected with an adaptive threaded connection structure, so that the relative position adjustment of the second plate body 12 on the first plate body 11 is realized through the rotation process of the locking ring 123 on the corresponding pin rod 122, and the corresponding adjustment of the locking ring 123 makes the retaining edge 121 surrounding the edge of the second plate body 12 block the edge of the first plate body 11. At the same time, after the second plate body 12 is installed, the The sensor 112 is correspondingly installed at the position of the corresponding through hole 111 on the second plate body 12, and the detection direction of the sensor 112 is in the corresponding movement direction of the pin rod 122 when the second plate body 12 slides relative to the first plate body 11, completing the assembly process of the toe guard body 1, and then when the toe guard body 1 is fixed on the mounting frame 101, according to the installation requirements and the corresponding installation position of the toe guard body 1 compared to the bottom of the elevator 100, the corresponding position of the second plate body 12 can be appropriately adjusted by rotating the lock ring 123 so that it is flush with the corresponding installation surface of the elevator 100. At the same time, by adjusting the installation position of the corresponding sensor 112 on the first plate body 11, when the second plate body 12 is subjected to force, the pin rod 122 on it has an appropriate detection distance along the corresponding moving direction of the through hole 111, and the circuit of the sensor 112 can be connected to the main control circuit of the elevator 100, completing the overall installation and connection process of the toe guard body 1.The structural setting of the elevator 100 toe guard board body 1 is combined with the connection method of the first plate body 11 and the second plate body 12. The second plate body 12 can slide in the corresponding direction in response to abnormal conditions such as bulges on the pit wall during operation of the elevator 100 through the setting of multiple sets of compression springs 13 between the second plate body 12 and the first plate body 11, and play a certain buffering role, which can further reduce the wear of the toe guard board body 1 and the stability of its overall structure. The setting of the retaining edge 121 on the second plate body 12 can effectively reduce the entry of internal dust. At the same time, when the elevator 100 is running and passengers are going up and down, if foreign objects fall, the foreign objects slide downward along the door gap of the elevator 100 and are correspondingly stuck on the bottom toe guard board body 1. The second plate body 12 can slide along the door gap under the action of multiple sets of compression springs 13. A corresponding moving distance is generated in the direction approaching the first plate body 11, and the corresponding pin rod 122 and lock ring 123 arranged thereon are driven to move in the corresponding direction on one side of the first plate body 11. At the same time, when the pin rod 122 and the lock ring 123 move to the detection range of the sensor 112 at the position of the corresponding through hole 111 on the second plate body 12, the corresponding sensor 112 is triggered and sends an alarm signal to the main control line of the elevator 100 through the signal line, so that the elevator 100 can stop running. An abnormal situation of the toe guard body 1 can be promptly reported, thereby reducing the operating risk of the elevator 100 and ensuring the safety of passengers during operation. In addition, the connection structure between this toe guard body 1 and the mounting frame 101 is also relatively simple, which is convenient for daily inspection and subsequent maintenance operations, and improves the convenience and flexibility of the installation process.
[0023] like Figure 2 or Figure 3 As shown, the mounting frame 101 includes multiple groups of channel steels arranged horizontally and vertically and of different sizes and connected by bolts 110. The corresponding channel steels connected to the second plate body 12 and the corresponding connecting surfaces between the multiple groups of channel steels arranged horizontally and vertically are provided with slide grooves 1011. The mounting frame 101 structure composed of the multiple groups of channel steels arranged in this way can, on the one hand, further improve the structural strength and supporting effect of the mounting frame 101, and also facilitate the installation and disassembly process; on the other hand, the adaptive slide grooves 1011 provided on the corresponding channel steels can also facilitate the adjustment and fixation of the corresponding connection positions between the multiple groups of channel steels for the structure of the toe guard body 1, and can also facilitate the installation position of the toe guard body 1 on the mounting frame 101, and cooperate with the corresponding structure at the bottom of the elevator 100 to perform the corresponding height adjustment process, further improving the convenience and efficiency of the installation process, and meeting different installation requirements.
[0024] See also Figure 4The second plate body 12 is surrounded by a retaining edge 121, and an open structure is set in the contact position with the bottom of the elevator 100 corresponding to the installation direction of the toe guard body 1. The opening structure corresponding to the retaining edge 121 on the second plate body 12 can ensure the structural stability of the second plate body 12 while further reducing the resistance of the second plate body 12 when it moves relative to the first plate body 11 due to external force, thereby improving the alarm sensitivity of this toe guard body 1 for abnormal situations and its effect. In addition, the second plate body 12 structure set with this structure also facilitates the connection process with the bottom of the elevator 100, reducing unnecessary limitations during the installation process.
[0025] The corresponding retaining edge 121 of the second plate 12 can also be detachably mounted with an adapted third plate 1211 structure, such as Figure 4 As shown in the figure, the third plate body 1211 is installed on the corresponding position of the retaining edge 121 on the second plate body 12 by the bolt member 110. The addition of the third plate body 1211 structure can further improve the connection stability between the second plate body 12 and the first plate body 11, and can cooperate with the locking ring 123 to enhance the corresponding position limiting effect of the second plate body 12 along the moving direction away from the first plate body 11, thereby improving the structural compactness of this toe guard body 1 and its overall strength stability.
[0026] The second plate 12 is also provided with a second compression spring 14 on the corresponding pin 122. Figure 5 As shown, the addition of the second compression spring 14 corresponding to the pin rod 122 can further improve the stability of the pin rod 122 during movement, further improve the stability of the second plate body 12 during movement relative to the first plate body 11, improve the shock-absorbing effect of the second plate body 12 and correspondingly improve the detection effect and detection stability of the sensor 112 used for detecting the moving position of the pin rod 122.
[0027] like Figure 5 As shown, the compression spring 13 and the second compression spring 14 are both installed at corresponding positions on the board surface of the first plate body 11 through a detachable structure, and the compression spring 13 and the second compression spring 14 are correspondingly clamped by multiple sets of snap structures 115 arranged around the corresponding positions on the board surface of the first plate body 11, thereby facilitating the installation, disassembly and replacement of the compression spring 13 and the second compression spring 14, further improving the disassembly and assembly efficiency of this toe guard body 1.
