[0001] The present invention relates to the technical field of disassembly and assembly of fixtures, and particularly to a disassembly and assembly tool for a cover-type fixture. Background Art

[0002] As a main transmission medium for the communication system in the tunnel of the rail transit field, the leaky cable must ensure that the leaky cable remains immovable in the face of any sudden variables in the tunnel to guarantee the train operation safety.

[0003] Among them, the cover-type fixture is the most widely used type of fixture. Through the closed structure of the cover and the base, it effectively prevents the destructive impact of the high-pressure wind formed by the train running in the tunnel on the leaky cable fixing device; the cover-type fixture includes: a base and a cover; the base and the cover are hinged through a connecting bearing; one side of the cover is provided with a shaft connection buckle, and the other side is provided with a buckle; one side of the base is provided with a bearing connection seat, and the other side is provided with a buckle receiving cavity; the buckle is engaged and clamped with the buckle receiving cavity in a matching manner.

[0004] However, during the installation process of the cover-type fixture, it is necessary to manually press and engage the upper cover and the lower base. And during the fixing process of the leaky cable, a fixture needs to be installed every one meter, and the workload is extremely large. At the same time, since the cover of the fixture is relatively fragile and cannot be installed by gravity hammering, during the installation process, manual installation is laborious and inefficient. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that manual installation is laborious and inefficient in the prior art during the installation process of the fixture, so as to provide a disassembly and assembly tool for a cover-type fixture.

[0036] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] A disassembly and assembly tool for a cover-type fixture provided in this embodiment, as Figure 1 shown, has an installation structure for installing a cover 12-type fixture; the installation structure includes: a pressing plate 1 and a hanging plate 2; after the hanging part of the hanging plate 2 is hooked to the fixture, the pressing surface of the pressing plate 1 abuts against the upper surface of the cover 12 of the fixture, forming a lever fulcrum. By pressing the other end of the pressing plate 1 downward, using the lever principle, a smaller force can be used to achieve the buckling of the base 11 and the cover 12 in the fixture. During the buckling process, it saves labor for the operator, improves the installation efficiency, can ensure that the fixture can be installed in place, and avoids damage to the fixture caused by hammering.

[0038] One of the fixtures targeted by the disassembly and assembly tool provided in this embodiment, as Figure 2 、 3 shown, the fixture includes a cover 12 and a base 11, and the base 11 and the cover 12 are hinged through a connecting bearing; one side of the cover 12 is provided with a shaft connection buckle, and the other side is provided with a buckle 13; one side of the base 11 is provided with a bearing connection seat 15, and the other side is provided with a buckle receiving cavity 14; the buckle 13 is adaptively engaged and snapped with the buckle receiving cavity 14. Of course, the disassembly and assembly tool can be used for any fixture with a basic structure.

[0039] As Figure 4As shown, the pressing plate 1 is in the shape of a flat plate. The pressing plate 1 has a pressing surface, and the pressing surface abuts against the upper surface of the cover plate 12; one end of the pressing plate 1 is provided with a first ear plate 3; anti-slip baffles 4 are oppositely arranged on both sides of the middle position of the pressing plate 1. During the pressing process, the anti-slip baffles 4 are on both sides of the cover plate 12, which can limit the sliding of the pressing plate 1 and facilitate applying force to the cover plate 12.

[0040] As Figure 5 shown, it is a schematic three-dimensional structure diagram of the hanging plate 2. One end of the hanging plate 2 has a hanging end 5 arranged at an angle. The hanging end 5 is embedded inside the base 11 of the fixture to form a first stress point; the other end of the hanging plate 2 is provided with a second ear plate 6;

[0041] The pressing plate 1 and the hanging plate 2 are rotationally connected by passing a screw 7 through the mounting holes between the first ear plate 3 and the second ear plate 6. A pre-tightening nut 8 is screwed at one end of the screw 7. When the disassembly and assembly tool is not in use, the pressing plate 1 and the hanging plate 2 can be buckled, and then the pre-tightening nut 8 is tightened to temporarily fix the pressing plate 1 and the hanging plate 2, which is convenient for carrying.

[0042] One end of the pressing plate 1 away from the hanging plate 2 extends to form a plug-in plate 9, and a butting protrusion 10 is arranged on the plug-in plate 9;

[0043] As an alternative implementation, the plug-in plate 9 can also be separately provided and slidably arranged with the pressing plate 1.

[0044] Usage method and principle

[0045] The disassembly and assembly tool provided in this embodiment assists the fixture locking process as follows:

[0046] Rotate the hanging plate 2 so that the hanging plate 2 and the pressing plate 1 are placed at a right angle or other angles. The hanging end 5 of the hanging plate 2 fits with one or more positions of the base 11 to form a first stress point; specifically, the hanging end 5 can abut against the lower end of the bearing connecting seat 15;

[0047] The pressing plate 1 is aligned with the upper part of the cover plate 12. The cover plate 12 of the applicable fixture can be in the shape of an arc, a flat plate, etc., and forms a lever fulcrum. The two anti-slip baffles 4 of the pressing plate 1 can limit the left and right sliding of the handle, making it more convenient to apply force to the pressing plate 1.

[0048] Press the pressing plate 1 towards the base 11 of the fixture. Using the lever principle, the force received by the cover plate 12 is greater than the force applied by our hand to the pressing plate 1, so that the buckle of the cover plate 12 enters the buckle receiving cavity 14 of the base 11, that is, there is a "click" sound, realizing the engagement of the cover plate 12 and the base 11, indicating that the locking installation process of the fixture is completed.

[0049] The disassembly tool provided in this embodiment assists in the disassembly of the fixture as follows:

[0050] Open the folded disassembly structure, insert the insertion plate 9 into the space between the buckle and the lower end of the buckle receiving cavity 14. The abutting protrusion 10 on the insertion plate 9 abuts against the buckle of the fixture cover plate 12. With the top end of the insertion plate 9 as the fulcrum, rotate the insertion plate 9 towards the direction of the fixture cover plate 12, so that the abutting protrusion 10 forms a thrust on the buckle, causing the buckle to pop out of the buckle receiving cavity 14, indicating that the fixture cover plate 12 has been opened.

[0051] The disassembly and assembly tool provided in this embodiment can ensure the installation efficiency of the fixture, save labor and improve efficiency when the installation workload of the fixture is huge. Moreover, it can ensure the installation meshing quality and proper installation of the fixture, and there will be no problems such as loose buckles and insufficient meshing due to a large number of repeated snap buttons, and it can also avoid damage to the fixture caused by hammering. At the same time, it has the function of disassembling the fixture, and can solve the problem of inability to disassemble when the cover plate 12 type fixture needs to be adjusted and disassembled after meshing.

[0052] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
