[0001] This utility model belongs to the field of maintenance equipment and relates to fire protection maintenance technology, specifically a positioning device for fire protection maintenance. Background Technology

[0002] Fire protection maintenance is an important measure to ensure the normal operation of fire safety systems and to eliminate fire hazards in a timely manner. It mainly involves maintenance measures such as inspection and cleaning of fire alarm systems, emergency lighting and evacuation indicator lights and other related facilities.

[0003] The reference patent title is: A fire protection facility maintenance mechanism (patent publication number: CN220574132U). Through the setting of the cleaning mechanism, under the pushing action of the pushing mechanism, the maintenance personnel, while standing, can make the cleaning cloth move laterally and reciprocate longitudinally on the surface of the safety exit sign by holding the handle, thereby ensuring the cleaning quality of the surface of the safety exit sign without the need for maintenance personnel to bend over repeatedly for cleaning.

[0004] However, the following problems exist when implementing the above technical solutions: The above devices mainly involve placing the cleaning mechanism corresponding to the safety exit sign, and then using a higher pushing mechanism to make the cleaning cloth inside the cleaning mechanism clean the surface of the safety exit sign; however, under normal circumstances, the safety exit sign is a certain distance from the ground. During use, the above devices can only ensure that the cleaning cloth adheres to the safety exit sign under the action of the spring, making it difficult to ensure that the height of the device remains constant during use. Therefore, it is necessary to lift the device manually during use, and the structure also needs to be pulled during the lifting process. This requires one hand or one leg to support the entire device, which places high demands on the physical strength of the operator.

[0005] Therefore, this utility model proposes a positioning device for fire protection maintenance. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a positioning device for fire protection maintenance. This positioning device solves the problem that existing safety exit signs are difficult to keep in position relative to the ground during cleaning, requiring the operator to support them and placing high demands on the operator's physical strength during use.

[0007] To achieve the above objectives, a positioning device for fire protection maintenance is proposed according to an embodiment of the first aspect of this utility model, comprising a plurality of supporting rods and a plurality of supporting columns, wherein the supporting rods are all fixedly connected to the side of the U-shaped frame away from the L-shaped plate; the interior of the supporting rods is slidably connected to the surface of the supporting columns;

[0008] The cross-section of the support column is a combination of a cylinder and an isosceles trapezoid. The dimension of the support column near the support rod is smaller than the dimension away from the support rod. The surface of the support column is provided with sliding grooves, and the length of the sliding grooves is less than the length of the support column.

[0009] Each of the receiving rods is slidably connected to a sliding shaft, and the sliding shaft is adapted to the sliding groove.

[0010] An operating rod is rotatably connected inside the receiving rod. A through groove is opened inside the operating rod. A transfer rod is fixedly connected to the surface of the receiving rod. The transfer rod and the through groove are adapted to each other. The cross-section of the operating rod is teardrop-shaped. The size of the operating rod decreases in the direction of the sliding shaft. The operating rod is in contact with the sliding shaft. The distance from the center of the through groove to the edge of the operating rod is different.

[0011] Optionally, a movable shaft is fixedly connected to the surface of the sliding shaft, a movable groove is provided inside the receiving rod, the movable shaft is adapted to the movable groove, and a movable spring is fixedly connected between the movable shaft and the movable groove.

[0012] Optionally, a movable column is rotatably connected inside the support column, and a caster wheel is fixedly connected to one end of the movable column away from the receiving rod.

[0013] Optionally, a limiting groove is formed inside the support column, the cross-section of the limiting groove is arc-shaped, and the universal wheel is slidably connected to the limiting groove.

[0014] Optionally, a movable rod is slidably connected inside the support column, the movable rod passes through the support column, and the length of the movable rod is greater than the diameter of the cylindrical position of the support column and less than the length of the trapezoidal base of the support column.

[0015] Optionally, a protruding post is fixedly connected to the surface of the movable rod, and a spiral groove is formed inside the movable post, with the protruding post and the spiral groove being adapted to each other.

[0016] Optionally, a ring spring is fixedly installed inside the through groove, and the two ends of the ring spring are fixedly connected to the operating rod and the central rotating rod, respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: A receiving rod and a support column sliding inside the receiving rod are set on the side of the safety exit sign cleaning device near the ground. Thus, during cleaning, there is a structure that can support the position of the cleaning device. The receiving rod and the support column are connected by rotating a simple operating rod to make the sliding shaft and the sliding groove fit together, thereby fixing the position of the receiving rod and the support column. The position of the receiving rod and the support column can be adjusted according to different positions, so that the cleaning device has good support during use. Therefore, when cleaning the surface of the safety exit sign, only the structure that moves the cleaning cloth back and forth needs to be operated, which reduces the difficulty of operation and makes it easier to use.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1-5 As shown, a positioning device for fire protection maintenance includes several supporting rods 1 and several supporting columns 2, wherein each supporting rod 1 is fixedly connected to the side of the U-shaped frame 3 away from the L-shaped plate 4.

[0030] It should be noted that the surfaces of the U-shaped frame 3 and the L-shaped plate 4 are provided with the same structure as in the reference patent, which can enable the cleaning of dust from the surface of the safety exit sign.

[0031] The inside of the receiving rod 1 is slidably connected to the surface of the support column 2;

[0032] The cross-section of the support column 2 is a combination of a cylinder and an isosceles trapezoid. The dimension of the support column 2 near the support rod 1 is smaller than the dimension away from the support rod 1. The side of the support column 2 away from the support rod 1 is provided with a rounded corner. The rounded corner makes the surface of the support column 2 smooth and without sharp edges, so that there is no need to worry about the edges scratching the operator when the whole device is used. Moreover, the dust that falls on its surface can slide off along the edge after the rounded corner is set.

[0033] Each of the support columns 2 has a sliding groove 51 on its surface, and the length of the sliding groove 51 is less than the length of the support column 2.

[0034] Each of the support rods 1 is slidably connected to a sliding shaft 52, which is adapted to a sliding groove 51. The friction between the sliding shaft 52 and the sliding groove 51 is relatively large. By fitting the sliding shaft 52 and the sliding groove 51 together, the sliding of the support column 2 inside the support rod 1 can be restricted.

[0035] An operating rod 53 is rotatably connected inside the receiving rod 1. A through groove 54 is formed inside the operating rod 53. A central connecting rod 55 is fixedly connected to the surface of the receiving rod 1, and the central connecting rod 55 and the through groove 54 are adapted to each other. The cross-section of the operating rod 53 is teardrop-shaped, and its size decreases towards the sliding shaft 52. The operating rod 53 contacts the sliding shaft 52. The distance from the center of the through groove 54 to the edge of the operating rod 53 varies. Because the distance from the center of the through groove 54 to the edge of the operating rod 53 varies, the state between the operating rod 53 and the sliding shaft 52 differs when the operating rod 53 rotates to different positions. Consequently, the fit between the sliding shaft 52 and the sliding groove 51 is affected. When the operating rod 53 is at its smallest position and contacts the sliding shaft 52, the sliding shaft 52 and the sliding groove 51 are tightly fitted, restricting the sliding between the support column 2 and the receiving rod 1.

[0036] In practical application, this fire safety maintenance positioning device has a support rod 1 and a support column 2 that slides inside the support rod 1 on the ground side of the safety exit sign cleaning device. During cleaning, the structure can support the position of the cleaning device. The support rod 1 and the support column 2 are fixed by rotating the simple operating rod 53 to make the sliding shaft 52 and the sliding groove 51 fit together. The position of the support rod 1 and the support column 2 can be adjusted according to different positions, so that the cleaning device has good support during use. When cleaning the surface of the safety exit sign, only the structure that moves the cleaning cloth back and forth needs to be operated, which reduces the operation difficulty and makes it easier to use.

[0037] In some specific implementations, a movable shaft 61 is fixedly connected to the surface of the sliding shaft 52, and a movable groove 62 is provided inside the receiving rod 1. The movable shaft 61 is adapted to the movable groove 62, and a movable spring 63 is fixedly connected between the movable shaft 61 and the movable groove 62. When the movable spring 63 is in a relaxed state, there is a distance between the sliding shaft 52 and the sliding groove 51.

[0038] In some specific implementations, a movable column 71 is rotatably connected inside the support column 2. A caster wheel 72 is fixedly connected to one end of the movable column 71 away from the receiving rod 1. A limiting groove 73 is formed inside the support column 2. The cross-section of the limiting groove 73 is arc-shaped. The caster wheel 72 is slidably connected to the limiting groove 73. The angle of the limiting groove 73 further limits the angle that the caster wheel 72 can rotate, so that when the caster wheel 72 is perpendicular to the ground, it can drive the entire device to move and rotate to change its position.

[0039] In a further embodiment, a movable rod 74 is slidably connected inside the support column 2. The movable rod 74 passes through the support column 2, and its length is greater than the diameter of the cylindrical part of the support column 2 and less than the length of the trapezoidal base of the support column 2. A protruding column 75 is fixedly connected to the surface of the movable rod 74. A spiral groove 76 is opened inside the movable column 71, and the protruding column 75 is adapted to the spiral groove 76. Thus, one end of the movable rod 74 protrudes from the surface of the support column 2. By changing the position of the movable rod 74, the position of the movable column 71 and the universal wheel 72 can be changed. Thus, the universal wheel 72 can be rotated and retracted and used by simply pushing the support column 2 in different directions. Thus, when moving the device, the universal wheel 72 can be rotated to expose the support column 2, and the universal wheel 72 makes the movement of the device easier. When using the device to clean the surface of the safety exit sign, the movable wheel is retracted, so that the support column 2 and the receiving rod 1 can support the cleaning device.

[0040] In some specific implementations, a ring spring 81 is fixedly installed inside the through groove 54, and the two ends of the ring spring 81 are fixedly connected to the operating rod 53 and the central rotating rod 55, respectively.

[0041] The working principle of this utility model:

[0042] When moving the U-shaped frame 3, push the moving rod 74. The sliding of the moving rod 74 causes the protruding column 75 to change its position inside the moving column 71. The moving column 71 is rotated through the spiral groove 76. The rotation of the moving column 71 causes the caster wheel 72 to rotate towards the ground. When the moving rod 74 can no longer be pushed, the caster wheel 72 is parallel to the ground. At this time, push the L-shaped plate 4. Under the action of the caster wheel 72, the whole device can be quickly moved and changed position.

[0043] When cleaning the safety exit sign, first attach the cleaning cloth inside the U-shaped frame 3 to the safety exit sign. Then, rotate the operating rod 53 inside the receiving rod 1 to make the edge of the operating rod 53 that is closer to the through groove 54 contact the sliding shaft 52. At this time, the sliding shaft 52 slides away from the support column 2 under the action of the moving spring 63, and then the sliding shaft 52 and the sliding groove 51 separate. The support column 2 will slide down on its own under the action of gravity. After the support column 2 slides down to contact the ground, rotate the reset operating rod 53, and then the sliding shaft 52 and the sliding groove 51 contact, restricting the position between the receiving rod 1 and the support column 2, and supporting the position of the U-shaped frame 3.

[0044] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
