This will cause the operator's thumb to be more laborious due to continuous force application for rolling, and in actual installation, it is difficult to ensure that the force applied by the operator to the seat body remains constant all the time, which easily causes the depth of the seal strip pressed into the sealing groove on the installation plate to be uneven, and there is a situation where a part of the seal strip is not completely pressed into the installation groove. The uneven installation of the seal strip results in a poor sealing effect. Content of the Utility Model

[0022] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0023] When installing the sealing strip, it is often necessary for workers to press it in by hand or use a wooden hammer to knock it in. However, installing by hand is time-consuming and laborious, and when using a wooden hammer to knock, it is easy to damage the sealing strip. The prior art cited in the background art discloses a tool for installing the sealing strip of a switch cabinet door. When installing the sealing strip, the sealing strip passes through the bottom of the rolling wheel, and the sealing strip that is not connected to the mounting plate extends out from the upper end of the guiding channel. When the rolling wheel is used to roll the sealing strip, the sealing strip is connected to the mounting plate on the cabinet door. However, during the entire installation process of the sealing strip, in order to ensure that the installation depth of the sealing strip is uniform, it is especially necessary for the operator to roll the sealing strip above the seat body with a uniform force, which is not only laborious, but also difficult to ensure that the force applied by the operator to roll the seat body remains constant during actual installation, easily resulting in uneven installation depth of the sealing strip. That is, after the sealing strip is installed, the distance between the top of the sealing strip and the bottom of the mounting plate is not uniform, and the sealing effect is difficult to guarantee.

[0024] The present invention provides a sealing strip installation tool improved on the basis of the prior art to solve the problems existing in the prior art described above. Moreover, the sealing strip installation tool provided by the present invention is particularly suitable for installing the sealing strips of various electrical equipment such as high and low voltage switch cabinets and box-type substations, so as to ensure that the sealing strip is completely pressed into the installation groove, thereby reliably guaranteeing the sealing effect, and further enabling the sealing state of the electrical equipment to meet the corresponding protection level and be safely used.

[0025] The overall design concept of the sealing strip installation tool provided by the present invention is as follows: As Figures 1 - 3 shown, a sealing strip installation tool includes a mounting frame 8. Oppositely arranged rolling members and backing members are mounted on the mounting frame 8. A space between the rolling members and the backing members is used for the sealing strip 9 and the mounting plate 10 to pass through. The backing member is used to move along the side of the mounting plate facing away from the installation groove. The rolling member is a rolling wheel located on the side facing the installation groove and used to roll the sealing strip into the installation groove. The distance between the surface of the backing member in contact with the installation groove and the rolling surface of the rolling wheel satisfies the requirement of completely pressing the sealing strip into the installation groove.

[0026] During use, the operator first presses one end of the sealing strip 9 into the installation groove of the mounting plate 10 so that the sealing strip 9 and the mounting plate 10 can be inserted between the backing member and the rolling member. Then, the mounting frame 8 is pushed towards the other end of the sealing strip 9 and the mounting plate 10. During the process of the backing member moving along the mounting plate 10, the rolling member rolls along the sealing strip 9 and rolls the sealing strip 9, so as to gradually roll the sealing strip 9 into the installation groove on the mounting plate 10, thereby completing the installation of the sealing strip 9.

[0027] Compared with the prior art that requires the operator to always press on the seat body, which is not only laborious but also difficult to ensure that the force is always applied evenly, easily leading to uneven installation of the sealing strip, the sealing strip installation tool provided by the present utility model defines the distance between the top of the sealing strip 9 and the bottom of the mounting plate 10 after installation through the distance between the surface of the backrest member in contact with the installation groove and the rolling surface of the rolling wheel. During the overall installation process, the operator only needs to push the sealing strip installation tool along the extension direction of the sealing strip 9 and the mounting plate 10, which can ensure that the sealing strip 9 is evenly and smoothly pressed into the sealing groove completely, effectively ensuring the installation quality of the sealing strip 9, reducing the labor intensity of the operator, and improving the installation efficiency of the sealing strip 9.

[0028] Based on the above overall introduction of the present utility model, a more specific embodiment is provided on the basis of the overall introduction as follows:

[0029] This embodiment focuses on a detailed description of the rolling member and the backrest member.

[0030] During the process of the operator pushing the sealing strip installation tool along the extension direction of the sealing strip 9 and the mounting plate 10, the backrest member moves along the mounting plate 10. The backrest member is a fixing plate fixedly installed on the mounting frame 8, and the fixing plate is perpendicular to the mounting frame 8 and is a flat plate. Thus, during the process of pushing the mounting frame 8 to move, the fixing plate translates along the mounting plate 10. Of course, in other embodiments, the backrest member is a fixing rod fixedly arranged on the mounting frame 8, which can reduce the friction during the movement to a certain extent and reduce the labor intensity of the operator.

[0031] The rolling member rolls and presses the sealing strip 9 during its rolling process. The rolling member is a rolling wheel rotatably installed on the mounting frame 8 through a rotating shaft. Setting the rolling member as a roller can reduce the manufacturing difficulty of the sealing strip installation tool and save the manufacturing cost.

[0032] To further improve the installation efficiency of the sealing strip, the backrest member is a rolling wheel rotatably installed on the mounting frame. At this time, during the process of the operator pushing the mounting frame 8, the rolling wheel and the rolling wheel rotate in the opposite direction and synchronously to roll the sealing strip 9 into the installation groove.

[0033] Preferably, in this embodiment, the rolling wheel is a grooved wheel 7 with annular grooves formed on its wheel surface. The bottom annular surface of the annular groove constitutes the rolling surface, and the two side edges of the annular groove are used to guide the sealing strip into the annular groove. The grooved wheel 7 has a guiding effect on the sealing strip 9, avoiding the situation where the sealing strip 9 is misaligned during installation and requires manual handling by the operator. It can ensure that the sealing strip 9 is restricted between the two side edges of the annular groove during the rotation of the grooved wheel 7. Then, during the rotation of the grooved wheel 7, the rolling surface formed by the bottom of its annular groove rolls on the sealing strip 9 to accurately and reliably press the sealing strip 9 into the installation groove. Further, the two side walls of the annular groove are used to be stuck on the outer sides of the two side walls of the installation groove and constitute the guiding groove walls that cooperate with the side walls of the installation groove. Thus, through the guiding cooperation between the installation groove and the grooved wheel 7, when the operator pushes the installation frame 8 to move, the path of the grooved wheel 7 is more accurate and the rolling effect on the sealing strip 9 is better.

[0034] To further improve the installation effect of the sealing strip, the rolling linear speed of the rolling wheel is set to be equal to the rolling linear speed of the rolling wheel, so as to reduce the friction on the surface of the sealing strip and avoid the situation where one moves too slowly on the sealing strip and the installation plate while the other rotates multiple times in the same place due to too fast a speed, thereby causing wear to the surface of the sealing strip. The rolling wheel and the rolling wheel are set as rollers of equal size, which is not only beneficial to the installation of the sealing strip but also convenient for the manufacture of the sealing strip installation tool. Of course, in other embodiments, the rolling wheel and the rolling wheel can also be set as rolling wheels of unequal size. The smaller-sized roller rolls faster, and the larger-sized roller rolls slower to roll the sealing strip and the installation plate.

[0035] A driving gear 1 is installed on the installation frame through a rotating shaft. The other end of the rotating shaft is installed with a crank for the operator to operate to rotate the driving gear 1. The rotating shaft of the driving gear constitutes the rotational input end to drive the rolling wheel to rotate. The rotational input end and the rolling wheel are connected by gear meshing transmission. Specifically, a rolling shaft is rotatably installed on the installation frame 8. Gear teeth 4 are circumferentially arranged at the root of the rolling shaft to form a rolling wheel with a shaft gear structure. Through the cooperation between the gear teeth 4 and the driving gear 1, the rolling wheel can be driven to rotate by rotating the crank. In other embodiments, a mating gear 6 meshing with the driving gear can also be fixed on the rolling wheel, so that the rotational input end drives the mating gear 6 to rotate through the driving gear 1, thereby driving the rolling wheel to rotate. Operating the crank to rotate the driving gear, the rolling wheel can be rotated through the gear teeth or the mating gear. During the movement of the sealing strip installation tool, the backrest moves on the installation plate 10, so that the rolling wheel rolls the sealing strip during the rolling process to install the sealing strip. Of course, when the backrest is a rolling wheel, the rolling wheel can also be driven to rotate through the rotational input end, which is the same as the setting of driving the rolling wheel to rotate through the rotational input end described above and will not be elaborated here.

[0036] In order to further ensure the uniform installation of the sealing strip 9, it is set that the rotation of the input end can drive the rolling wheel and the rolling press wheel to rotate in opposite directions simultaneously. The input end of rotation is meshed and driven with the rolling wheel or the rolling press wheel through a speed increasing gear set. A reversing gear 5 is also installed on the mounting bracket 8 to achieve the reverse rotation of the rolling wheel and the rolling press wheel. The reversing gear can be meshed and connected with the rolling press wheel or the rolling wheel with a shaft gear structure, or a mating gear can be fixedly fitted on the rolling member or the rolling press wheel and meshed with the reversing gear. Thus, when the crank is rotated, on the one hand, the driving gear directly drives the rolling press wheel or the rolling wheel with a shaft gear structure to rotate, or the driving gear drives the rolling press wheel or the rolling wheel to rotate through the mating gear; on the other hand, the other roller rotates in the opposite direction through the speed increasing gear set including the driving gear and the reversing gear. At this time, the rolling wheel and the rolling press wheel roll along the extending direction of the sealing strip 9 and the mounting plate 10 driven by the input end of rotation. Compared with the situation where the operator pushes the rolling member of the sealing strip 9 installation tool to make it roll, the friction on the surface of the sealing strip 9 is reduced, effectively avoiding the wear on the surface of the sealing strip 9 and affecting the appearance.

[0037] Specifically, as Figures 1 - 3 shown, taking the grooved wheel 7 as the rolling press wheel as an example, a mating gear 6 meshed and connected with the reversing gear 5 is provided on the grooved wheel 7. The reversing gear 5 is simultaneously meshed and connected with the driving gear 1, and the driving gear 1 is meshed and driven with the teeth 4 on the rolling shaft. At this time, the rolling wheel has a gear shaft structure. When the crank is rotated to make the driving gear 1 rotate, the driving gear 1 directly drives the rolling wheel to rotate, and the grooved wheel 7 rotates in the opposite direction relative to the rolling wheel through the reversing gear 5, so that the rolling wheel rolls along the mounting plate 10, and the grooved wheel 7 rolls along the sealing strip 9 to press the sealing strip 9 into the mounting groove on the mounting plate 10.

[0038] Based on the above overall introduction of the present utility model, a more specific embodiment is provided on the basis of the overall introduction as follows:

[0039] As Figures 1 - 2 shown, the mounting bracket includes a main board body. Two opposite rolling members are arranged on one side of the main board body. A crank is connected to the input end of rotation, and the crank is on the other side of the main board body. A handle 2 for the operator to hold is provided on the main board body on the side where the crank is located. The operator can rotate the handle 2 to make the rolling member rotate through the input end of rotation.

[0040] A holding part 3 is arranged at the bottom of the mounting bracket 8. The operator can hold the holding part 3 to facilitate the stable grasping of the sealing strip 9 installation tool. Specifically, the holding part 3 is a handle integrally formed with the mounting bracket 8 for the operator to hold, or it can also be fixedly connected to the mounting bracket 8 through bolts.

[0041] The edges and corners of the main board body of the mounting bracket 8 are rounded structures, which are safer during use, avoiding scratching the operators, and are also convenient for storage and arrangement. They can be stored together with the unsealed sealing strip 9 without wearing the sealing strip 9.

[0042] To further facilitate operation, the part of the crank handle for the operator to hold is a cylinder, which is beneficial for the operator to hold and rotate the rotary input end 1.

[0043] It should be noted that, among the various specific technical features described in the above specific embodiments, without contradiction, they can be combined in any appropriate way. To avoid unnecessary repetition, the present utility model does not separately describe various possible combination methods.

[0044] In addition, any combination can be made between various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, it should also be regarded as the content disclosed by the present utility model.

[0045] The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model. The patent protection scope of the present utility model is subject to the claims. All equivalent structural changes made by using the description and drawings of the present utility model should be included in the protection scope of the present utility model by the same token.
