Description
The technical field is as follows:
the utility model relates to a switch door stop device, in particular to press rope formula inspection door opening stopper belongs to transportation technical field.
Background art:
when the inspection door is opened to overhaul electrical equipment in the rail transit, the maximum opening degree of the door needs to be limited, and the door is prevented from being opened too much and colliding with other parts. At present, after the connecting rod type stopper commonly used is used for a period of time, the check door sinks due to overlarge manufacturing clearance and insufficient lubrication of a lock shaft and a connecting rod or deformation of a door hinge, and the stopper often generates abnormal sound and even noise.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: the pressure rope type check valve opening limiter overcomes the defects of the prior art, and is simple in structure, convenient to use and easy to install.
The utility model discloses a technical scheme who solves technical problem and take is:
the rope pressing type opening limiter for the inspection door comprises two fixing blocks, a pin shaft, a limiting rope and two fixing blocks, wherein the middle parts of two side edges of each fixing block are respectively provided with a groove, the limiting rope consists of a middle part, a fixing part and cylindrical holes, the number of the cylindrical holes is two, and a matched pin shaft is inserted into each cylindrical hole; the upper end and the lower end of the front surface of each fixed block are respectively provided with a bolt hole; one end of the limiting rope sequentially penetrates through the two bolt holes formed in one fixing block through bolts and is fixedly connected with the door panel, and the other end of the limiting rope sequentially penetrates through the two bolt holes formed in the other fixing block through bolts and is fixedly connected with the door frame.
The middle part, the fixing part and the cylindrical hole are of an integrated structure, the two ends of the limiting rope form the cylindrical hole in a flanging sewing mode, and the middle part of the limiting rope forms an overlapped structure in a flanging sewing mode.
The size of the fixed parts at the two ends of the limiting rope is matched with the size between the grooves on the two side edges of the fixed block.
The fixing parts of the limiting ropes respectively penetrate through the bolt holes through bolts to be fixed with the corresponding door frames and the corresponding door plates, and the middle parts of the limiting ropes are distributed in a U shape.
The utility model discloses an actively beneficial effect is:
1. the utility model discloses simple structure, the maintenance rate is low, replaces the stopper of original connecting rod formula, avoids in the use because lock axle and connecting rod make the clearance too big, lubricated not enough, and hinge deformation leads to the inspection door to sink, and the stopper sends the condition of abnormal sound, and the preparation is convenient, easily installs.
2. The utility model is used for on the inspection door on the track traffic, adopt the bolt to pass the bolt hole on the fixed block and be connected the both ends of spacing rope with the door plant or the door frame that correspond, replace lock axle and connecting rod with spacing rope and fixed block, when avoiding traditional stopper trouble, because lock axle or connecting rod cause the damage to electrical equipment, door plant, door frame too hard.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an exploded view of FIG. 1;
FIG. 3 is one of the usage state diagrams of the utility model;
fig. 4 is a second usage state diagram of the utility model.
The specific implementation mode is as follows:
the invention will be further explained and explained with reference to the drawings, in which:
referring to fig. 1-4, a rope pressing type opening limit device for an inspection door comprises pin shafts 1, limiting ropes 2 and fixing blocks 3, wherein the number of the fixing blocks 3 is two, the middle parts of two side edges of each fixing block 3 are respectively provided with a groove 3-2, each limiting rope 2 consists of a middle part 2-2, a fixing part 2-3 and a cylindrical hole 2-1, the number of the cylindrical holes 2-1 is two, and a matched pin shaft 1 is respectively inserted into each cylindrical hole 2-1; the upper end and the lower end of the front surface of each fixed block 3 are respectively provided with a bolt hole 3-1; one end of the limiting rope 2 sequentially penetrates through two bolt holes (3-1) arranged on one fixing block 3 through bolts 4 and is fixedly connected with the door plate 6, and the other end of the limiting rope 2 sequentially penetrates through two bolt holes 3-1 arranged on the other fixing block 3 through bolts 4 and is fixedly connected with the door frame 5; wherein: the middle part 2-2, the fixing part 2-3 and the cylindrical hole 2-1 are of an integrated structure, two ends of the limiting rope 2 form the cylindrical hole 2-1 in a flanging sewing mode, and the middle part 2-2 of the limiting rope 2 forms an overlapped structure in a flanging sewing mode; the sizes of the fixing parts 2-3 arranged at the two ends of the limiting rope 2 are matched with the sizes of the grooves 3-2 arranged on the two side edges of the fixing block 3; the fixing parts 2-3 of the limiting rope 2 respectively pass through bolt holes through bolts to be fixed with the corresponding door frame 5 and the corresponding door panel 6, and the middle parts 2-2 of the limiting rope 2 are distributed in a U shape.
Fig. 3 is a view showing a state where the door panel is not opened (closed), and fig. 4 is a view showing a state where the door panel is opened.
When the utility model is used, two sets of rope pressing type check door opening position limiters are respectively arranged on the upper part and the lower part of each door plate and each door frame; the method comprises the following steps that cylindrical holes at two ends of a limiting rope are respectively inserted with a pin shaft, then the middle parts of two sides of the limiting rope are respectively inserted into bolt holes in fixed blocks through bolts and are fixed with a corresponding door plate and a corresponding door frame, the two fixed blocks are fixed on the door plate and the door frame which are measured in advance in a parallel mode, after installation is completed, the middle part of the limiting rope is in a U shape, and the pin shaft arranged in the cylindrical holes plays a role in limiting the fixed blocks; when the door plate is opened, as shown in the fourth drawing, the two ends of the limiting rope are fixed and cannot move through the pin shaft, and the length of the limiting rope is set in advance, so that when the door plate is opened to a certain angle, the limiting rope can limit the inspection door.
Attention is paid in the actual installation, the size of door plant and door frame aperture is relevant with "U" type degree of spacing rope middle part, so before the staff installation, will be according to the length of spacing rope, measure two fixed positions in advance, if the distance between two fixed blocks is too big, the radian undersize of spacing rope middle part can appear, the aperture of door also can the undersize then, if the distance undersize between two fixed blocks, the radian of spacing rope middle part can appear is too big, the door plant aperture can appear too big, other equipment can be touched to the door plant.
The utility model discloses rational in infrastructure, simple manufacture easily installs, can not produce the abnormal sound in the use, has improved holistic comfort level, and with low costs and occupation space are little, has fine social practical value, easily promotes.
