Изобретение относитс к измерительной технике в лабораторных услови х предпри тий обувной промышленности и касаетс прибора дл испытани геленочной части обуви.The invention relates to measuring equipment in the laboratory of enterprises of the footwear industry and relates to a device for testing the gelenochnaya part of shoes.

Известен прибор дл испытани изделий на изгиб, например геленочной части обуви, состо щий из приспособлени дл креплени изделий, содержащего две опоры, расположенного в стороне от оси приложени нагрузки на изделие и установленного подвижно относительно этой оси, динамометра со стрелкой и индикатора со стрелкой 1.A known device for testing articles in bending, for example, the gelenochny part of shoes, consisting of a device for fastening products, containing two supports located away from the axis of application of the load on the product and installed movably relative to this axis, a dynamometer with an arrow and an indicator with arrow 1.

Недостаток этого прибора заключаетс в том, что с его помощью может быть определена жесткость геленочной части дл одного положени без учета нагружений, возникающих в естественных услови х носки.The disadvantage of this device is that it can be used to determine the stiffness of the gelenochny part for one position without taking into account the loads that occur under natural conditions of wear.

С целью оценки жесткости геленочной части обуви при различных схемах нагружени и закреплени испытуемых образцов, а также измерени жесткости геленочной части в местах наибольших нагружений в услови х носки в предлагаемом приборе приспособление дл креплени изделий имеет зажим, шарнирно-закрепленный на одной из опор, и жестко св занный со стрелкой индикатора.In order to assess the stiffness of the gelenochnaya part of the shoe under various schemes of loading and fixing the tested samples, as well as measuring the stiffness of the gelenochnaya part in the places of the greatest loadings under the conditions of wear in the proposed device, the device for fastening products has a clamp that associated with the indicator arrow.

На фиг 1 показан предлагаемый прибор, вид спереди; на фиг. 2 - то же, вид по стрелке А на фиг. 1.Fig 1 shows the proposed device, front view; in fig. 2 is the same, view along arrow A in FIG. one.

Прибор имеет станину со столиком 1, на котором смонтировано приспособление дл креплени испытуемых изделий, содержащее две опоры 2 и 3. Опора 3 вл етс дополнительной и примен етс в случае испытани издели на двух опорах.The device has a stand with a table 1 on which a device for fastening the tested products is mounted, containing two supports 2 and 3. Support 3 is optional and is used in the case of testing the product on two supports.

Одна из опор имеет зажим 4, шарнирно-закрепленный на оси 5, вокруг которой он может быть повернут на требуемый угол испытани издели и зафиксирован болтом 6. Столик с приспособлением смонтирован на станине при помощи винтовой колонки 7 с зажимными гайками 8 дл установки его на нужной высоте.One of the supports has a clamp 4 hinged on the axis 5, around which it can be rotated to the desired angle of the product test and fixed with a bolt 6. The little table with the fixture is mounted on the frame using a screw column 7 with clamp nuts 8 to install it on the desired height.

Нагружеиие издели осуществл етс стержнем 9 со съемным наконечником 10, перемещаемым в роликовых направл ющих 11, фиксирующих стержень вдоль оси приложени нагрузки на изделие.The loading products are carried out by a rod 9 with a removable tip 10 moved in roller guides 11 fixing the rod along the axis of application of the load on the product.

Приспособление дл креплени изделий расположено в стороне от оси приложени нагрузки на изделие, дл помещени которого на заданном рассто нии от этой оси до места креплени в зажиме приспособлениеThe device for fastening the products is located away from the axis of application of the load on the product, for placing it at a given distance from this axis to the place of attachment in the clamp device

Стержень 9 подвешен к перекладине 13, контактирующей с динамометром 14, св занным с рейкой 15, наход щейс в зацеплении с шестерней 16, сид щей на валу 17, несущемThe rod 9 is suspended from the bar 13, which is in contact with the dynamometer 14 connected to the rail 15, which is engaged with the gear 16, which sits on the shaft 17, carrying

flywheel 18. The entire system is mobile, balanced by means of load 19 and block 20, mounted on the frame. The amount of movement of the rod is measured by the indicator 21. The indicator 22 measures the angle of deflection, and its arrow is rigidly connected to the hinge support. There is a dynamometer 23 for measuring the load. The device operates as follows. The test article 24 is secured in the clamp 2 in the desired position, and the platform with the fixed article is set at a predetermined distance from the axis of application of the load. Table 1 is raised to contact with the tip 10 of the rod 11. The loading of the test product is made by turning the handwheel 18 and its numerical value is counted according to the indication of the arrow 23 of the gauge. 5 10 15 20 The claims of the device for testing products for bending, for example, the gelenochnaya part of shoes, consisting of a device for fastening products, containing two supports, located away from the axis of application of the load on the product and installed movably relative to this axis, a dynamometer with an arrow of the indicator with an arrow, characterized in that, in order to determine the stiffness and strength of the gelling part of a shoe according to various loading patterns, the device for fastening products has a clip hinged on one of the pore and tightly connected with the indicator hand.
