Abstract
The utility model discloses a bolt device special for a classroom door. The bolt device comprises a bolt and insertion holes, wherein the bolt is arranged on the door and the insertion holes are formed in positions on a door frame and corresponding to the position of the bolt; the bolt device further comprises a support plate which is arranged on a position on the door frame and corresponding to the position of the bolt; the support plate is capable of rotating in all the directions on the door frame; a plurality of insertion holes are formed in the support plate in rows; a returning device is arranged on the door frame; when the device is not used, the support plate is fixed on the side surface of the door frame through the returning device. Due to the design that the plurality of insertion holes are formed in the support plate, the openness of a gap of the door is controlled by inserting the bolt in the different insertion holes; after the device is used, the support plate is returned to the position on the side surface of the door frame through the returning device, the normal use can not be affected and students can not be scratched; besides, the bolt device special for the classroom door is simple in structure, convenient to use, and capable of ensuring the circulation of indoor air in cold winter and keeping the room warm and comfortable.
Description
Technical field
The utility model relates to the improvement of door body structure, specifically a kind of classroom door inserted pin special device.
Background technology
Classroom is the place of students study, ventilates very important, and ventilation well just can make in classroom with fresh air, is conducive to student and better learns.But winter, the door and window in classroom was all closed due to cold weather, although indoor warm, but cause room air not circulate, affect Students ' Learning, the words that window is opened, window is directly in the face of outdoor, interior temperature certainly will decline very fast, have plenty of the door in classroom is opened, but the gap that can not open is again too large, suitable gap should be 10 centimeters of left and right, but such folding angle cannot be controlled at present.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of classroom door inserted pin special device, can control the gap that classroom door is opened, and guarantees room ventilation, and circulation of air, makes student at a home from home learning.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of classroom door inserted pin special device, comprise latch and jack, it is upper that described latch is arranged at door, and jack is arranged at position corresponding with latch on doorframe, and this bolt device also comprises gripper shoe, described gripper shoe is arranged at position corresponding with latch on doorframe, described gripper shoe all directions on doorframe are rotated, and are disposed with a plurality of jacks in described gripper shoe, are provided with resetting means on doorframe, not the used time, described gripper shoe is fixed on the side of doorframe by resetting means.
Described gripper shoe adopts the material of inhaling mutually with magnet to make, and described resetting means is set to magnet, and described magnet is fixed on position corresponding to gripper shoe end, doorframe side.
Described gripper shoe adopts plastic material to make, described resetting means is set to retainer ring and elastic rope, described retainer ring is fixedly installed on the below of doorframe side gripper shoe end correspondence position, and described elastic rope one end is fixed on retainer ring, the other end gripper shoe that removably connects.
The utility model is by a plurality of jacks in design gripper shoe, by latch, insert the gap size that the mode control gate body of jack is opened, with finishing, by resetting means, gripper shoe is resetted in doorframe side, do not affect normal use, can scratch student, simple in structure, easy to use, guarantee at cold room air circulation in winter, snugness.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of another embodiment of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
1 is a specific embodiment of the present utility model as shown in Figure 1, this classroom door inserted pin special device, comprise latch 1 and jack 2, described latch 1 is arranged on door, jack 2 is arranged at position corresponding with latch 1 on doorframe, this bolt device also comprises gripper shoe 3, described gripper shoe 3 is arranged at position corresponding with latch 1 on doorframe, described gripper shoe 3 all directions on doorframe are rotated, in described gripper shoe 3, be disposed with a plurality of jacks 2, on doorframe, be provided with resetting means 4, not the used time, described gripper shoe 3 is fixed on the side of doorframe by resetting means 4.
The syndeton of described gripper shoe 3 and doorframe, adopts and existingly can realize that it is a bit fixing and can all directions rotate in doorframe side.In the present embodiment, doorframe side is fixedly installed a spherical shape connector 31, described gripper shoe 3 one end arrange circular-arc breach, suitable with spherical shape connector 31, the circular-arc breach of described gripper shoe 3 wraps spherical shape connector 31 and it can be rotated along spherical shape connector 31 to all directions.
As a kind of embodiment of resetting means 4, as shown in Figure 1, described gripper shoe 3 adopts the material of inhaling mutually with magnet to make, and described resetting means 4 is set to magnet, and described magnet is fixed on position corresponding to gripper shoe 3 ends, doorframe side.
During use, gripper shoe 3 is pulled out, by latch 1, insert the gap that suitable jack 2 control gates are opened, with finishing, after gripper shoe 3 is decontroled, gripper shoe 3 is rotated downwards by gravity, by magnet adsorption on doorframe side.
Another embodiment as resetting means 4, as shown in Figure 2, described gripper shoe 3 adopts plastic material to make, described resetting means 4 is set to retainer ring 41 and elastic rope 42, described retainer ring 41 is fixedly installed on the below of doorframe side gripper shoe 3 end correspondence positions, described elastic rope 42 one end are fixed on retainer ring 41, and the other end is removably connected on the hole of gripper shoe 3 ends.During use, the other end of elastic rope 42 ties up on the hole of gripper shoe 3 ends, gripper shoe 3 is pulled out, by latch 1, insert jack 2, the gap that control gate is opened, with finishing, the elastic reaction by elastic rope 42 retracts doorframe side by gripper shoe 3, elastic rope 42 is got off from the end solution of gripper shoe 3, gripper shoe 3 and retainer ring 41 are fixed together by elastic rope 42.Certain this mode will be by manually realizing, and the reset mode of magnet, slightly more complex relatively, is not to facilitate so.According to the needs of service condition, resetting means 4 also can adopt other structure, as long as can realize, gripper shoe 3 is reset to doorframe side and resets.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
