Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The embodiment discloses an electronic sight hole lamp, as shown in fig. 1 and 2, including protection frame 1, equipment box 2 and connecting plate 3, protection frame 1 is served to one towards connecting plate 3 and is fixed and is provided with a plurality of blocks 4 that insert that are the whole column of circumference and distribute, connecting plate 3 is served to one towards protection frame 1 and is fixed and be provided with and insert the arrangement piece 5 that blocks 4 correspond the setting, all open on a plurality of arrangement pieces 5 and supply to insert blocks 4 and correspond and insert arrangement groove 6.

As shown in fig. 2 and 3, the insertion block 4 is provided with a first connection hole 7, the installation block 5 is provided with a second connection hole 8 communicated with the installation groove 6, and when the insertion block 4 is inserted into the installation groove 6, the first connection hole 7 is aligned with the second connection hole 8, so as to facilitate the subsequent fixed connection between the protection frame 1 and the connection plate 3. One side of the connecting plate 3 close to the protective frame 1 is fixedly provided with a fixing block 9 corresponding to the mounting block 5, the fixing block 9 is provided with a sliding groove 10, a fixing strip 13 is positioned in the sliding groove 10, one end of the fixing block 9 far away from the connecting plate 3 is provided with a transverse groove 11 for conducting the sliding groove 10, and one end of the fixing strip 13 facing the transverse groove 11 is integrally formed with a handle 12 penetrating through the transverse groove 11. By providing the handle 12 to facilitate a worker to apply force to the fixing strip 13, there is an effect of facilitating pulling of the fixing strip 13. Sliding tray 10 internal fixation is provided with extension spring 15, extension spring 15's one end and fixed block 9 fixed connection, extension spring 15's the other end and fixed strip 13 fixed connection, when pulling handle 12 to the direction that is close to settling groove 6, extension spring 15 will drive fixed strip 13 and remove to the direction that is close to settling block 5 owing to reseing, make fixed strip 13 pass first connecting hole 7 and second connecting hole 8 automatically, extension spring 15's design has the effect that makes things convenient for the workman to operate, fixed strip 13 passes first connecting hole 7 and second connecting hole 8 in proper order to realize the preliminary fixed between protection frame 1 and the connecting plate 3. The end of the fixing strip 13 inserted into the first connecting hole 7 first is an arc end 16, which has the effect of guiding the fixing strip 13 to be inserted into the first connecting hole 7.

As shown in fig. 2 and 4, a spring plate 20 is fixedly disposed at an end of the fixing block 9 close to the transverse slot 11, and when the protection frame 1 needs to be separated from the connecting plate 3, the handle 12 is pulled toward an end far from the mounting block 5, and the handle 12 drives the fixing block 9 to move toward a direction far from the mounting block 5. Until the fixing strip 13 is pulled to one end of the spring piece 20 far away from the placing groove 6, at the moment, the fixing strip 13 is abutted to one end of the spring piece 20 far away from the placing groove 6, and the fixing strip 13 is subjected to certain elasticity under the action of the spring piece 20, so that the fixing strip 13 is not inserted into the first connecting hole 7 and the second connecting hole 8 any more and is limited by the spring piece 20 so as to conveniently move the protection frame 1 out of the connecting plate 3.

As shown in fig. 3 and 5, a storage groove 17 communicating with the first connection hole 7 is dug in the insertion block 4, a limiting spring 18 is fixedly arranged in the storage groove 17, and a spring plate 19 is fixedly arranged at the other end of the limiting spring 18. The part of the fixing strip 13 inserted into the storage slot 17 is physically opened with a concave slot 25 for inserting the spring plate 19. When the fixing strip 13 passes through the storage slot 17, the limiting spring 18 applies a force towards the direction of the protection frame 1 to the spring plate 19, the limiting spring 18 drives the spring plate 19 to move, the spring plate 19 is inserted into the concave slot 25, one end of the fixing strip 13 is abutted against the spring plate 19, the other end of the fixing strip 13 is abutted against the slot bottom of one end, close to the protection frame 1, of the storage slot 17, and the fixing strip 13 is fixed in the storage slot 17. When spring plate 19 inserts in sunken groove 25, spring plate 19 and fixed strip 13 butt each other, prevent under the effect of external force, and fixed strip 13 breaks away from in first connecting hole 7 and the second connecting hole 8, has the effect of the stability of being connected between increase protection frame 1 and the connecting plate 3. The movement of the fixing bar 13 is further restricted so that the fixing bar 13 is not easily moved.

As shown in fig. 2 and 3, a handle 21 is integrally formed on a side of the spring plate 19 away from the connecting plate 3, a first communication hole 22 communicating with the storage slot 17 is formed on an end of the mounting block 5 away from the connecting plate 3, a second communication hole 23 aligned with the first communication hole 22 is formed on the insertion block 4, the handle 21 is inserted into the second communication hole 23 through the first communication hole 22, and a part of the handle 21 is extended out of the mounting slot 6. The handle 21 is designed to facilitate a worker's control of the movement of the spring plate 19 through the handle 21 so that the fixing bar 13 can be taken out of the storage slot 17 by pulling the handle 21 for multiple uses. The grip 21 is provided with the stripe 24 for increasing friction, and since the solid portion of the grip 21 protruding out of the button placement groove 6 is short, by providing the stripe 24 on the grip 21 so that a worker can abut the stripe 24 through the fingernail or the skin of the finger to increase friction, when pulling the grip 21, it is not difficult to pull the grip 21 due to slipping.

The following describes the effects of the present embodiment with reference to the working conditions:

when needs are fixed protection frame 1 on connecting plate 3, insert piece 4 earlier and insert to corresponding arrangement groove 6 that sets up, first connecting hole 7 aligns with second connecting hole 8 this moment, remove fixed strip 13 to the direction that is close to arrangement piece 5 again, make fixed strip 13 pass first connecting hole 7 and second connecting hole 8 in proper order, this moment because restriction spring 18 drives spring plate 19 and removes to the direction that is close to protection frame 1, and say that spring plate 19 inserts to the depressed groove 25 in, with the removal of restriction fixed strip 13, further restrict the removal of protection frame 1, make protection frame 1 relatively fixed in on connecting plate 3, be convenient for the workman fix connecting plate 3 and protection frame 1, the effect that has convenient explosion-proof audible-visual annunciator installation. When the protection frame 1 needs to be detached from the connecting plate 3, the spring plate 19 is separated from the concave groove 25 by pulling the handle 21, then the handle 12 is pulled to enable one end of the fixing strip 13 to be abutted against one end, far away from the mounting block 5, of the spring piece 20 so as to limit the fixing block 9 to rebound back to the storage groove 17 again, and when all the fixing strips 13 are moved out of the storage groove 17, the protection frame 1 is lifted towards the direction far away from the connecting plate 3, so that the protection frame 1 is lifted; the connecting plate 3 is separated from the protective frame 1.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
