Description
Technical Field
[0001] This utility model belongs to the field of insulating cover technology, and in particular relates to an insulating cover with a tenon joint structure. Background Technology
[0002] In today's power systems, safe and stable operation is a crucial core element. Protecting the live parts of electrical equipment, such as transformer terminals and cable grounding boxes, has become a key aspect of ensuring the reliable operation of the power system. Insulating covers, as an important protective device, have emerged to address this need. Their main function is to effectively prevent accidental contact by humans, small animals, or debris, thereby avoiding power outages and electric shock accidents, and providing a solid guarantee for the stable operation of the power system.
[0003] However, the existing insulating protective covers are all fixed, which makes it inconvenient for staff to disassemble them when they need to be replaced, and needs to be improved. Utility Model Content
[0004] The purpose of this utility model is to provide an insulating cover with a tenon joint structure. Through the squeezing force of the clamping block, the components such as the fixing block, the slot, the connecting plate, the hollow tube, the connecting spring, the sliding rod, and the fixing plate cooperate with each other, so as to pull the push handle fixed on the side of the rectangular block, thereby causing the rectangular block to be pushed downward, thus solving the existing problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an insulating cover with a tenon joint structure, comprising a first insulating cover and a second insulating cover. The second insulating cover is disposed on the side of the first insulating cover. A tenon and mortise mechanism is provided on the top of the first insulating cover. The tenon and mortise mechanism includes a fixing block, which is fixedly connected to the top of the first insulating cover. A slot is provided on the front side of the fixing block. A connecting plate is fixedly connected to the top of the second insulating cover. A hollow tube is fixedly connected to the rear side of the connecting plate. A connecting spring is fixedly connected to the inner wall of the hollow tube. A sliding rod is fixedly connected to the end of the connecting spring away from the hollow tube. A fixing plate is fixedly connected to the end of the sliding rod away from the hollow tube. A locking block is fixedly connected to the rear side of the fixing plate. A rectangular block is fixedly connected to the circumferential surface of the sliding rod. A push handle is fixedly connected to the side of the rectangular block.
[0006] Furthermore, a concave plate is fixedly connected to the bottom of the second insulating cover, and an insert plate is fixedly connected to the bottom of the first insulating cover. The design of the insert plate and the concave plate helps to enhance the adhesion between the first insulating cover and the second insulating cover.
[0007] Furthermore, the side cross-section of the fixing block is set to a trapezoidal shape, and the card block is engaged with the inner wall of the card slot. The trapezoidal side cross-section of the fixing block facilitates the card block to squeeze it.
[0008] Furthermore, the side cross-section of the card block is set to an arc shape, and the sliding rod is slidably connected to the inner wall of the hollow tube. The arc shape of the side cross-section of the card block facilitates the compression of the fixed block.
[0009] Furthermore, the insert plate is snapped into the inner wall of the concave plate, and the initial state of the connecting spring is set to a relaxed state. The design of the connecting spring is beneficial to drive the sliding rod to reset when the connecting spring is no longer subjected to compressive force, so that the locking block enters the slot.
[0010] Furthermore, a protective mechanism is provided inside the first insulating cover. The protective mechanism includes a shock-absorbing spring, and a protective disc is fixedly connected to the end of the shock-absorbing spring away from the first insulating cover. The design of the protective mechanism is beneficial for protecting the power equipment and preventing damage when it is dropped or squeezed.
[0011] Furthermore, the protective mechanism is configured in two sets, with the other set of protective mechanisms located on the inner side wall of the second insulating cover. The provision of two sets of protective mechanisms is beneficial for better protection of the power equipment.
[0012] This utility model has the following beneficial effects: This invention utilizes the squeezing force of the locking block to drive the components such as the fixing block, locking groove, connecting plate, hollow tube, connecting spring, sliding rod, and fixing plate to work together. This enables the push handle fixed to the side of the rectangular block to be pulled, thereby giving the rectangular block a downward pushing force. When the rectangular block is given a downward pushing force, the sliding rod sliding on the inner wall of the hollow tube slides towards the inner wall of the hollow tube. The sliding rod drives the locking block to move and disengage from the inner wall of the locking groove. When the protective cover needs to be replaced, it is convenient for the staff to disassemble and replace it.
[0013] This invention utilizes components such as shock-absorbing springs and protective discs to achieve downward concavity of the first and second insulating covers under pressure. This causes the shock-absorbing springs and protective discs to move downwards and contact the surface of the electrical equipment. As the pressure increases, the shock-absorbing springs, under pressure, are in a taut state and reduce the transmission of pressure based on their elasticity. When the insulating covers are compressed, this invention can protect the product and prevent it from suffering significant damage.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5As shown, this utility model is an insulating cover with a tenon joint structure, including a first insulating cover 1 and a second insulating cover 2. The second insulating cover 2 is disposed on the side of the first insulating cover 1. The top of the first insulating cover 1 is provided with a tenon and mortise mechanism 3, which includes a fixing block 31. The fixing block 31 is fixedly connected to the top of the first insulating cover 1. A slot 32 is opened on the front side of the fixing block 31. The top of the second insulating cover 2 is fixedly connected to a connecting plate 33. A hollow tube 34 is fixedly connected to the rear side of the connecting plate 33. A connecting spring 35 is fixedly connected to the inner wall of the hollow tube 34. A sliding rod 36 is fixedly connected to the end of the connecting spring 35 away from the hollow tube 34. A fixing plate 37 is fixedly connected to the end of the sliding rod 36 away from the hollow tube 34. A locking block 38 is fixedly connected to the rear side of the fixing plate 37. A rectangular block 39 is fixedly connected to the circumferential surface of the sliding rod 36. A push handle 310 is fixedly connected to the side of the rectangular block 39.
[0020] As shown in the figure, the bottom of the second insulating cover 2 is fixedly connected to a concave plate 311, and the bottom of the first insulating cover 1 is fixedly connected to an insert plate 312. The design of the insert plate 312 and the concave plate 311 helps to enhance the adhesion between the first insulating cover 1 and the second insulating cover 2.
[0021] As shown in the figure, the side cross section of the fixing block 31 is set as a trapezoid, and the locking block 38 is locked into the inner wall of the slot 32. The trapezoidal side cross section of the fixing block 31 facilitates the locking block 38 to squeeze it.
[0022] As shown in the figure, the side cross-section of the locking block 38 is set to an arc shape, and the sliding rod 36 is slidably connected to the inner wall of the hollow tube 34. The side cross-section of the locking block 38 is set to an arc shape to facilitate the compression of the fixing block 31.
[0023] As shown in the figure, the insert plate 312 is snapped into the inner wall of the concave plate 311. The initial state of the connecting spring 35 is set to a relaxed state. The design of the connecting spring 35 is conducive to driving the sliding rod 36 to reset when the connecting spring 35 is no longer subjected to the squeezing force, so that the locking block 38 enters the locking groove 32.
[0024] As shown in the figure, the first insulating cover 1 is equipped with a protective mechanism 4 inside. The protective mechanism 4 includes a shock-absorbing spring 41. The end of the shock-absorbing spring 41 away from the first insulating cover 1 is fixedly connected to a protective plate 42. The design of the protective mechanism 4 is conducive to protecting the power equipment and avoiding damage when it is dropped or squeezed.
[0025] As shown in the figure, the protective mechanism 4 is set in two sets, and the other set of protective mechanism 4 is set on the inner side wall of the second insulating cover 2. Setting two sets of protective mechanisms 4 is beneficial to better protect the power equipment.
[0026] A specific application of this embodiment is as follows: When it is necessary to replace the first insulating cover 1 and the second insulating cover 2, the worker pulls the push handle 310 fixed to the side of the rectangular block 39, thereby causing the rectangular block 39 to be pushed downward. When the rectangular block 39 is pushed downward, the sliding rod 36 sliding on the inner wall of the hollow tube 34 slides towards the inner wall of the hollow tube 34. The sliding rod 36 drives the locking block 38 to move away from the inner wall of the locking slot 32. At the same time, the worker holds the first insulating cover 1 and the second insulating cover 2, and then pulls the first insulating cover 1 with force. The first insulating cover 1 and the second insulating cover 2 are installed so that the plug plate 312 is separated from the inner wall of the concave plate 311, making it easy to replace. Finally, when the first insulating cover 1 and the second insulating cover 2 are squeezed, the squeezed surfaces of the first insulating cover 1 and the second insulating cover 2 are concave downwards, thereby driving the shock-absorbing spring 41 and the protective plate 42 to move downwards to contact the surface of the power equipment. As the squeezing force increases, the shock-absorbing spring 41 is in a taut state when squeezed by the squeezing force, and reduces the transmission of the squeezing force according to its own elasticity, thereby protecting the power product.
