Известно соединение деталей с помощью угловой арматуры с загнутыми концами, которые вводятся в наружные пазы, выполненные вдоль внешних граней соединяемых деталей и внутренней осевой шпонки [1].It is known to connect parts using angular reinforcement with bent ends that are inserted into external grooves made along the outer faces of the parts to be joined and the internal axial key [1].

Однако данное соединение неудобно в ' эксплуатации, так как из-за раздельности крепежных элементов операция сборки трудоемка.However, this connection is inconvenient in operation because the assembly operation is laborious due to the separability of the fasteners.

Наиболее близким к предлагаемому по технической сущности и достигаемому эффек- ,5 ту является зажим для углового соединения деталей, преимущественно для деталей мебели, выполненный в виде пластины, на одном конце которой расположена головка, а · на другом — соединительный узел [2].Closest to the proposed technical essence and the achieved effect is the 5th clamp for the angular connection of parts, mainly for furniture parts, made in the form of a plate with a head at one end and a connecting unit at the other [2].

Однако и это соединение неудобно в эк- ²⁰сплуатации, так как операция сборки трудоемка из-за того, что соединение деталей с зажимом осуществляется с помощью крепежных элементов, например скрепок.However, this compound is inconvenient in ek- spluatatsii ^20, since the assembling operation is laborious due to the fact that the connection parts with a clip by means of fastening elements, for example staples.

Целью изобретения является улучшение условий эксплуатации за счет сокращения времени сборки.The aim of the invention is to improve operating conditions by reducing assembly time.

Указанная цель достигается тем, что, в зажиме, выполненном в виде пластины, на одном конце которой расположена головка, а на другом — соединительный узел, пластина по обе стороны снабжена ребрами, а соединительный узел выполнен в виде упругого элемента, причем ребра и упругий элемент снабжены фиксирующими выступами для соединения деталей.This goal is achieved by the fact that, in the clamp, made in the form of a plate, on one end of which there is a head, and on the other - a connecting unit, the plate is provided with ribs on both sides, and the connecting unit is made in the form of an elastic element, and the ribs and elastic element equipped with locking tabs for connecting parts.

На фиг. 1 изображен предлагаемый зажим; на фиг. 2 — возможные варианты выполнения зажима.In FIG. 1 shows the proposed clip; in FIG. 2 - possible embodiments of the clamp.

Зажим содержит пластину 1, на одном конце которой выполнена головка 2, а на другом — зажимной узел в виде упругого элемента 3. На пластине 1 по обе ее стороны выполнены ребра 4, снабженные фиксирующими выступами 5 и компенсатором натяга 6. Концы упругого элемента 3 снабжены фиксирующими ножевидными выступами 7, зацепами 8 и компенсаторами натяга 9. В соединяемых деталях 10 и 11 выполнены пазы 12 под концы упругого элемента и пазы 13 под ребра 4.The clamp comprises a plate 1, on one end of which a head 2 is made, and on the other a clamping unit in the form of an elastic element 3. On the plate 1, ribs 4 are provided on both sides thereof, provided with fixing protrusions 5 and an interference fitting 6. The ends of the elastic element 3 are provided locking knife-shaped protrusions 7, hooks 8 and interference compensators 9. In the connected parts 10 and 11, grooves 12 are made for the ends of the elastic element and grooves 13 for the ribs 4.

Зажим работает следующим образом.The clamp works as follows.

При сборке деталей 10 и 11 концы упругого элемента 3 вводят в пазы 12, после чего в пазы 13 вводят ребра 4. Ребра 4 и концы упругого элемента 3 удерживаются ₅в пазах 12 и 13 за счет фиксирующих выступов 5 и 7, а также зацепов 8, врезающихся в тело деталей 10 и 11.When assembling parts 10 and 11, the ends of the elastic element 3 are introduced into the grooves 12, after which the ribs 4 are introduced into the grooves 4. The ribs 4 and the ends of the elastic element 3 are held ₅ in the grooves 12 and 13 due to the fixing protrusions 5 and 7, as well as the hooks 8 crashing into the body of parts 10 and 11.

При введении ребер 4 в пазы 13 упругий элемент 3 деформируется. Возникшие при этом упругие силы плотно прижимают ю детали 10 и 11 к пластине 1, обеспечивая тем самым надежное соединение. Разъединение деталей происходит в обратном направлении.With the introduction of the ribs 4 into the grooves 13, the elastic element 3 is deformed. The resulting elastic forces tightly press the parts 10 and 11 to the plate 1, thereby ensuring a reliable connection. Separation of parts occurs in the opposite direction.

Применение изобретения в промышленности позволяет получить значительный эко- 15 номический эффект за счет высокой технологичности изготовления зажима и сокращения времени на операцию сборки.The application of the invention in industry makes it possible to obtain a significant economic effect due to the high manufacturability of the clamp and the reduction of time for the assembly operation.
